Description

  The present invention relates to a member for attaching a safety belt or the like so that work on a roof can be performed safely.

  In recent years, measures to promote longer life of ordinary houses are being promoted. With this measure, it is possible to extend the life of the house by continuously conducting inspections and repairs, and to continue to be a house that can live for a long period of time. Among the houses, the roof part is affected by the external environment for a long time and directly, so the deterioration progresses faster than the indoor space, and the degree of necessity for inspection and repair is high. On the other hand, since the roof is generally at a high position, there is a danger in inspection and repair. Therefore, it is desirable that a specialized worker performs it after adjusting safety equipment.

  In order to perform work safely on the roof, many facilities, members, methods and the like for the purpose of safe work are known. As an example of a metal fitting attached to a ridge for the purpose of safety work, there is an invention of Patent Document 1. According to the invention of this Patent Document 1, as shown in FIG. 41, a substantially mountain-shaped plate-like body 93 that includes a rope 91 and a guide ring 92 for fixing a lifeline 90 and is fixed across both sides of a roof ridge. And a pair of left and right slide plates 94 that are inserted and attached so as to be freely slidable on the left and right side pieces, and the slide plates are inserted into and hooked on the back side of the ridge roof component 95. It has.

  As a result, it is not necessary to use nails or screws, and the roof surface is not damaged, and the lifeline can be easily fixed to the rope.

  Moreover, there exists patent document 2 invention as a metal fitting of the same objective. According to the invention of this Patent Document 2, as shown in FIG. 42, a plurality of attachment portions 101 of the safety device 100 are fixed to an arbitrary roof surface with a fixture 102, and a connecting portion 103 and a safety cable integrally formed with the attachment portion are provided. The locking portion 104 is used to hook a carabiner or the like of a safety belt worn by the worker so as to make the worker safe.

  As a result, the mounting is relatively easy and the brackets are evenly attached to the roof, so it is easy to change the carabiner from one bracket to another when moving on the roof. Since the non-connected state during the change is short, it is possible to provide a safer environment for the worker.

JP2000-160792 JP-A-2005-273417

  However, in the invention of Patent Document 1, the metal fitting is large and the structure is complicated, and the number of parts is large. Further, since it is installed above the roofing material, there is a risk that the appearance of the roof will be noticeable or the deterioration will be accelerated because it is exposed to the outdoor environment. Moreover, in patent document 2 invention, since it fixes only on the single side | surface of a roof, ie, only in one direction, when a heavy load is applied, a safety implement will fall out by the fall of fastening strength and the retention strength of a roof surface. There was a possibility.

  In view of the above, the object of the present invention is a member having a safety function for work on the roof without making it conspicuous in appearance, and can be firmly fixed to the roof surface and stored outside when not required. The object is to provide a member that is not exposed to the environment and can be removed when necessary.

In order to solve the above-mentioned problems, the roof safety member of the present invention is a roof safety member 1 for safely performing work on the roof, and is attached to the field ground 61 across the roof ridge. And a connecting portion 4 in which at least one or more loops 41 are formed. The connecting portion is locked in a locking space formed by the fixing portion and the field ground 61. to adopt a configuration that are. Important is, is fixed to the sheathing roof board of the fixed part is in two roof surfaces constituting the roof, that it can be readily lock the connecting portion to the fixed portion fixed to the sheathing. In other words, since the fixing part is fixed from two directions, it can exhibit high fixing strength against the operator's sliding, which is pulling from one direction, and the connecting part even in a slight space composed of the base plate and the fixing part. Can be locked.

Further, as another means for solving the above-described problem, the roof safety member 1 for safely performing work on the roof, which is fixed to a substantially mountain shape that is attached to the field ground 61 across the roof ridge. Part 2 and a connecting part 4 in which at least one or more loops 41 are formed, and a purlin receiving part 5 is provided above the top of the fixing part 2, and the connecting part 4 is the fixing part or the purlin receiving The structure of being locked to the part is adopted. By employ | adopting this structure, a connection part can be easily latched to a fixing | fixed part or a purlin receiving part.

In order to more effectively exhibit the means for solving the above-described problems, the present invention adopts the following configuration.

First, one end of the connecting portion 4 is locked from above to a bent portion composed of the leg portion and the purlin receiving portion, and the other end hangs on the opposite side of the leg portion. Adopt the configuration. By adopting this configuration, the connecting part is locked by two different bent parts, so the leg part or purlin receiving part when a strong force is applied to the connecting part compared to that on a single surface The deformation of becomes difficult to occur.

Next, the connection portion 4 is exposed on the surface of the roof tile when in use, and is stored in the storage space 74 when not in use and is not exposed on the surface of the roof tile. By adopting this configuration, when necessary, the connecting portion is exposed on the surface of the roof tile and used to exert its effect. Since it is housed in the connecting portion, it is not unnecessarily exposed to the tile surface. That is, the connecting portion stored in the storage space can be taken out and used only when necessary, and can be stored in the storage space when it is no longer needed and held without deterioration until the next time it is necessary. In addition, since the connecting portion is not always exposed, it does not occur that the connecting portion flutters in a strong wind and hits the roof material.

  Further, in the storage space according to the present invention, the storage space 74 is a space constituted by the bottom side surface of the roof tile 71 and the head side rear surface of the upper roof tile 72 that is placed one step above the roof tile. adopt. By adopting this configuration, particularly in the case of roofing tiles, the roof tiles can be stored in vertically overlapping portions, and the storage operation of the connecting portion can be completed on the roof surface.

  Then, in this invention, the structure by which the accommodation position mark is provided in the loop 41 which is not latched in any of the said connection parts is employ | adopted. By adopting this configuration, even if the connecting portion is stored in the storage space in the above, the storage position mark remains on the roof tile surface, and therefore it is possible to specify without losing sight of the location of the storage space storing the connecting portion. As a premise, even if the connecting portion is stored in the storage space, the storage position mark is preferably sized so as to be always exposed on the tile surface.

On the other hand, with respect to the basic configuration of the present invention, a locking portion 3 is provided at or near the tip of the fixing portion 2, and the connecting portion is associated with any of the fixing portion, the locking portion, and the purlin receiving portion. By adopting the configuration of being stopped, it is possible to lock the connecting portion to a locking portion provided at the tip of the leg portion .

  The roof safety member of the present invention has a simple structure, can be easily and firmly fixed to the roof, and the entire range of the roof safety member is not exposed on the surface of the roof. Degradation can be greatly suppressed. As a result, the roof safety member is more inconspicuous due to the appearance of the roof.

  Examples of the present invention will be described in detail below. The roof in the present invention refers to a cover at the top of a building that has an inclined surface regardless of whether it is steep or gentle, and the inclined surface is covered with a roofing material. The roofing material is a building material that covers the roof, and is generally covered with the roof, and has a role of protecting the roof or the indoor environment against the outside environment. Roof materials include clay tiles, cement tiles and the like. The exposure on the surface of the roof tile refers to a range that can be visually recognized in the appearance when the roof tile is installed. Therefore, in this case, there is a portion that is not exposed due to the overlapping of the tiles even on the surface of the roof tile. The term “safety” used here refers to any work on the roof, such as inspections or repairs. Even if an accident such as sliding off the surface of the roof occurs, the worker should be able to work on the roof, such as the ground or the roof. It means that it can be kept on the roof without dropping from the surface.

  Next, the structure of the roof safety member 1 of the present invention will be described. The roof safety member 1 of the present invention is based on the fixed portion 2 and the connecting portion 4, and the locking portion 3 is provided at the tip (or near the tip) of the fixed portion, and the purse receiving portion 5 is provided at the top 23 of the fixed portion. Each is provided. For convenience, the fixing portion, the locking portion, and the purlin receiving portion may be collectively referred to as a main body.

  As shown in FIGS. 1 to 3, the shape of the fixing portion 2 is a cross-sectional view in the flow direction and a substantially mountain shape so that the fixing portion 2 can be fixed to two roof surfaces constituting the ridge. With this mountain shape, the two field grounds 61 can be mounted across. Then, the fixing part 2 can be fixed to the field ground 61 from two directions. As a result, even if a heavy load is applied to the roof safety member 1 when the operator 8 on the roof slides down from the roof surface, the roof safety member 1 is fixed to the field ground 61 from two directions. The pull-out strength is sufficiently obtained and the safety of the worker 8 is ensured. Furthermore, by attaching the surface to the ground surface 61 and attaching it directly, the fixing portion 2 itself is not easily bent or bent, and can be easily fastened.

In addition, in a state where the roof safety member is attached to the top of the ridge, the cross-sectional view of the fixed portion 2 is preferably such that the vicinity of the top 23 protrudes upward. More specifically, the vicinity of the top of the fixed portion 2 protrudes in a substantially U-shape opened downward, and the protruding height is preferably about 3 mm to 10 mm from the ridge core at the top of the field ground 61 (high The lower limit of the thickness is preferably higher than the thickness of the connecting portion described later). By this protrusion, it is possible to provide a locking space 27 surrounded by the two field grounds 61 and the fixed portion 2 constituting the roof. In this locking space 27, one end of a loop 41 of the connecting portion 4 to be described later is fitted. After the loop 41 is passed through the leg portions 28 at both ends of the fixing portion 2 to reach the locking space 27 , the fixing space 2 is fixed to the field ground 61 while maintaining the state. The loop 41 is locked to the locking space 27 as a non-moving space having no opening. That is, the loop 41 is not detached from the locking space 27 and is locked in a movable state within the locking space. As a result, even if the worker on the roof surface works at a position that is inclined with respect to the safety member for the roof, the connecting portion can change the direction to the operator side. The power is not added.

  Moreover, if the fixing | fixed part 2 is elongate in the flow direction by planar view at the time of attachment to the field ground 61, it will rarely be fixed to the edge part vicinity of a field board, and it will be firmly fixed to a roof surface. Further, as shown in FIGS. 2 and 3, several nail holes 21 are provided in the left and right leg portions 28 straddling the ridge. As an example, the nail holes 21 are provided on the left and right legs respectively in about 2 to 8, in particular, about 4 to 5, and further provided in two or more rows in the flow direction. And it is desirable to fix at least two or more of the nail holes. By arranging the nail holes 21 in two or more rows or setting a large number of nail holes 21, there are nail holes that cannot be fastened or are not suitable for fastening due to the circumstances of the base (field board or rafter). Even if there is, there is an alternative nail hole at the time of fixing the fixing portion, so it is flexible. In addition, it is desirable to use a screw for fastening the fixing portion. Since a screw having a screw thread is generally superior in pulling strength compared to a nail, the fixing portion can be fixed more strongly. The above-mentioned screw, especially if it is a so-called full screw that is provided without interruption to the screw head, even if the screw works only on the ground plate, the pullout strength compared to the case of the nail Is excellent.

  By the way, since the fixing | fixed part 2 is also the only site | part which fixes the safety member 1 for roofs to the field ground 61, the fixing strength of the member itself is also requested | required so that it can endure at the time of an emergency on the roof operator 8. . As an example, the plate thickness of the fixed portion 2 is desirably about 1.0 mm to 2.0 mm. If the plate thickness of the fixing part 2 is too thick, a part that interferes with the fixing part floats when the pier 62 is constructed, and it is necessary to process the pier to avoid the part. The length of the fixed portion 2 is preferably about 50 mm to 100 mm, and particularly preferably about 70 mm. The width of one fixing portion 2 is preferably about 20 mm to 40 mm, and particularly preferably about 25 mm to 30 mm.

  As shown in FIGS. 4 to 7, the locking portion 3 is arranged in the direction of the ridge or so as to cover the tip of the fixing portion 2 or the vicinity of the tip in the fixed state of the fixing portion 2 as described above. 61 is bent vertically upward. Depending on the bent shape of the locking part 3, it can be divided into two cases. First, as shown in FIGS. 4 to 5, the cross-sectional view includes a substantially L shape (or a substantially inverted L shape), a substantially inverted V shape, and the like. In addition to the bending process of these shapes, by providing a locking hole 31 at a predetermined location, for example, one end of the connecting portion 4 is passed through the locking hole 31 and a loop 41 is formed, and then at a portion close to one end of the wire. By closing with the caulking 42 or the like, the locking portion 3 and the connecting portion 4 can be connected. The connection described above is performed in advance at the manufacturing stage, so that the work at the site can be completed only by fastening the safety member 1 for roof to the field ground 61.

  As shown in FIGS. 6 to 7, the second pattern of the bent shape is a shape in which the connecting portion 4 is folded back toward the ridge top side, such as substantially U-shaped or substantially V-shaped in cross-sectional view. The advantage of this shape is that if the fixed part 2 and the locking part 3 that are integrally formed and the connecting part 4 as shown in FIG. 8 are prepared in advance as separate parts, the connecting part 4 can be easily hooked in the field. This is a possible point. The shape may be any shape as long as the connecting portion 4 can be easily locked and the opening 32 can be closed. In addition, the effect which can store and manage the safety member 1 for roof itself compactly can also be anticipated by making the fixing | fixed part 2, the connection part 4, and the latching | locking part 3 into separate parts.

  Taking the wire (wire material) as an example, the connecting portion 4 first forms a loop 41 in which both ends of the wire are closed in advance by caulking 42 or the like. As shown in FIG. 8, one end of the loop 41 is locked to the locking portion 3 or the locking space 27, and the loop 41 at the other end is exposed on the roof surface on which the roof tiles are sown in use. As shown in FIG. 9, a carabiner 83 provided on a rope 82 of a safety belt 81 worn by the operator 8 is hooked. Thereby, the fixing | fixed part 2 fixed to the field ground 61 and the operator 8 are connected via the connection part 4, the rope 82, and the carabiner 83. FIG. Even in the unlikely event of an operator's sliding down, if the rope is of an appropriate length, the operator can be kept on the roof surface without dropping from the roof surface during work such as a shed or the ground. Safety can be ensured.

  The fixing method of the locking portion 3 and the connecting portion 4 in the second pattern of the bent shape described above is that the fixing portion 2 is fixed at a desired position of the field ground 61 and the loop 41 at one end of the connecting portion 4 is built. The hook 3 is hooked so as to pass through from the side, and the hook 3 is fixed to the ground with the screw 22 after the hook. Thereby, the connection part 4 can be easily made into the state which cannot detach | leave from the latching | locking part 3 by attachment on the spot. In addition, as shown in FIG. 7, a warping claw 34 is provided at the most part of the folded portion of the locking portion 3, and the entrance of the locking portion is opened to a larger size, so that the locking portion of the connecting portion 4 can be opened. This is a desirable shape because it can be easily hooked to 3.

If the connecting portion 4 is formed from a plate material, as shown in FIG. 10 as an example, the connection portion between the fixed portion 2 and the connecting portion 4 by forming a hinge structure 33, the thickness and shape of the roofing The angle can be changed accordingly. The cross-sectional shape of the connecting portion 4 can also be changed as appropriate according to the thickness and shape of the roofing material, and a locking hole 31 is provided near the tip of the connecting portion 4 on the side not connected to the fixed portion 2 side (as an example) FIG. 11). The said locking hole has a structure connected with the carabiner 83 etc. of the safety belt | band | zone 81 similarly to the loop 41 when the connection part 4 is comprised with the wire. That is, in the case of a plate material, the connecting portion 4 and the eaves-side tip portion of the fixed portion 2 are directly connected via the hinge structure 33. In addition, although the board thickness of the connection part 4 connected by the hinge structure is made into the same thickness as a fixing | fixed part etc. as an example, it does not specifically limit and is changed suitably.

  As a development of the present invention, as shown in FIG. 12, the roof safety member 1 is used at predetermined intervals, and when connecting on the roof, the connecting portion 4 is exposed from the storage space 74 on the tile surface, The master rope 45 may be passed through the loop 41 of the connecting portion, and the carabiner 83 of the safety belt 81 worn by the operator 8 may be hooked at an arbitrary position of the master rope so that the work can be performed. Of course, since the master rope is fixed in a state where it does not come off the connecting portion, even if the operator 8 accidentally slides off the roof surface, the master rope is locked to the connecting portion 4 via the master rope 45. Therefore, the safety of the worker can be improved. On the other hand, when the work on the roof is finished, the master rope fixed to the connecting portion 4 is unwound and the connecting portion 4 is stored in the storage space 74, and the appearance of the roof is not disturbed. By putting in and out the storage space of the connecting portion 4, it is possible to construct a roof safety member using a master rope for each work on the roof.

  As shown in FIG. 13 and FIG. 14, for example, the purlin receiving portion 5 includes a support portion 51 formed upward from the vicinity of the top portion 23 of the fixing portion 2 described above, and a further upper portion from the upper end of the support portion. It is comprised with the receiving part 52 formed. The height of the support portion is set to a predetermined height depending on which ridge portion of the roof is constructed or the shape of the roof tile. The receiving portion 52 has a substantially U-shape with an opening in the upper side in a side view, and can support a purlin 64 to which the roof tile 73 can be fixed as will be described later. In addition, the receiving portion is provided with about 2 to 4 receiving portion nail holes 53 penetrating in a substantially horizontal direction in the construction state of the roof safety member, and the purlin is fixed using screws, nails or the like. Can do. Further, the integrally formed main body (fixing portion 2, locking portion 3, purlin receiving portion 5) is pivoted about the substantially central portion of the support portion 51 that is substantially S-shaped in plan view when attached to the field ground 61. It is a rotational symmetry.

  On the other hand, as shown in FIG. 15, a bent portion 24 (strictly speaking, between the leg portion 28 and the rising surface 25 of the fixed portion 2) composed of the fixed portion 2 and the purlin receiving portion 5. A rib 26 may be provided on the bent portion. The shape of the rib is such that, when the fixing portion 2 is attached to the field ground 61, it is pushed out in a convex arc shape outward from the locking space 27 side or the uppermost end of the leg in contact with the field ground. It has a shape. In a state where the roof safety member is attached to the ridge, the purlin 64 and several ridge tiles 73 are placed on the receiving portion of the roof safety member. On the other hand, since the roof safety member 1 is formed of a thin plate as described above, there is anxiety in terms of strength with respect to a force (for example, wind load) received from a direction perpendicular to the ridge core. . Therefore, by providing the ribs in order to give strength even to a thin plate, the bent portion 24 and its periphery have a three-dimensional shape rather than a simple thin plate. That is, since it does not easily deform with respect to the above-described force or the like, wobble or the like of the ridge can be reduced.

  The rib 26 described above exhibits strength against a force received from a direction perpendicular to the ridge core by having a certain size. As an example, the width of the rib 26 is desirably about 5 mm to 15 mm, and particularly preferably about 10 mm to 12 mm, with respect to a fixed portion having a width of 25 mm. Further, the height of the rib (the farthest point from the leg or the rising surface to the rib surface when the state before the rib is formed as a reference) is preferably about 1 mm to 3 mm, particularly about 2 mm to 2.5 mm. Is desirable. In addition, the rib is not so long toward the lower end side of the leg portion 28 so as not to interfere with the crosspiece 62 to be constructed near the building.

  Here, the locking method of the connecting portion with respect to the fixing portion (and the purlin receiving portion) is to lock one end of the connecting portion 4 to the bent portion from above. The above-mentioned “from above” refers to a state in which a loop is passed from the tip of the leg so that the caulking 42 of the connecting part is below the leg 28. Specifically, one end of the loop is locked from the smaller angle side of the two angles existing in the bent portion 24 constituted by the leg portion 28 and the rising portion 25, and the side not locked by the bent portion 24 The locking position of the connecting portion 4 is determined so that the loop of the loop hangs down toward the opposite leg portion. Thereby, even if a strong load is applied to the loop side to be connected to the worker side, the direction of the load is a direction that does not deviate from the bent portion, so that the hooking strength of the connecting portion 4 to the fixed portion is increased.

  As described above, when the connecting portion 4 is locked to the bent portion 24 and is installed so as to hang down in the leg direction, depending on the tensile strength, the connecting portion enters between the base plate and the leg portion 28 while floating. There is a risk that it will not be stopped and safety will not be perfect. Therefore, by locking the bent portion from above as described above, the wire is not detached from the main body even when a load is applied, and can contribute to safety work.

  The roof safety member 1 of the present invention is a member necessary for long-term inspection and repair for the purpose of prolonging the life of a house, and since it is a work that ensures safety, The durability of the member itself is required. The roof safety member 1 is preferably made of steel or synthetic resin, and particularly steel, especially stainless steel, is excellent in workability and durability and is also suitable as a material for the connecting portion. Moreover, when the material which concerns on the safety member 1 for roofs of this invention is a metal, it is possible to prevent deterioration by dissimilar metal contact corrosion, and also the fall of safety by making all into the same or equivalent material. It is.

  As shown in FIG. 8, the connecting portion 4 of the present invention is mainly composed of a wire (here, referred to as a wire), and provided with loops 41 closed by caulking 42 at both ends. As for the size of the loop, the inner diameter from the loop side end portion of the caulking portion to the farthest point of the loop is somewhat larger than at least the width of the fixing portion 2, and the loop 41 can be passed through the fixing portion 2. It is like that. For example, the thickness of the wire constituting the connecting portion is preferably about 1.5 mm to 4 mm, and particularly about 3 mm. The length between the loops at both ends of the connecting portion 4 is such that at least the locking space 27 or the portion where the one end of the loop 41 is locked to the locking portion 3, the other end of the loop 41 is closest to the upper roof tile 72. The length until it appears on the roof surface of the roof tile 71 laid down one step is desirable. More specifically, when one end of the connecting portion 4 is locked in the locking space 74, and the uppermost roof tile 72 at the ridge is housed in the real thing (the roof tile when it is placed as it is without adjusting the length). Assuming that the total length of the roof tile 71 is 350 mm and the distance between the top of the ridge and the pier at the ridge is 20 mm, the desired wire length is preferably about 400 mm to 650 mm, and particularly preferably about 450 mm to 550 mm. Of course, if the upper roof tile 72 at the ridge is a half-finished product (the one that does not fit neatly, the bottom side of the roof tile is cut to the required length), the required wire length will be shortened, as described below. Since the wire is stored in the storage space when not in use, the direction in which the wire becomes longer than the required length is not particularly limited, and it is desirable to adopt the best length from the viewpoint of cost, construction, and the like. In short, the loop 41 of the connecting part 4 appears firmly on the surface of the roof tile 71 that is wound one step below the building, and the safety belt 81 worn by the operator 8 can be connected without difficulty and is not used. Sometimes it is desirable to be able to keep the design of the roof housed in the storage space and tiled.

  Here, the material of the connecting portion 4 made of a wire is preferably made of SUS316 as an example. The connecting portion 4 is configured to be stored in the storage space as described above, but even if stored in the storage space, the connection portion 4 is not completely blocked from the outdoor environment, and naturally touches rainwater, outside air, and the like. There is. In the connecting portion of the present invention, the material is made of SUS316 that is more durable than SUS304, thereby ensuring safety over a long period of time. It was confirmed that SUS304 is easily rusted because the wire itself becomes magnetic due to the processing in manufacturing the wire. Actually, in order to verify the durability by the corrosion acceleration test, when a wire made of SUS304 was tested with a testing machine (salt water tester STP-V90 manufactured by Suga Test Instruments Co., Ltd.), red rust was generated after about 60 hours. On the other hand, SUS316 was unable to confirm the state of corrosion. Therefore, it is desirable to select SUS316 as the wire material.

  A part of the connecting portion 4 is exposed to the surface of the roof tile 71 when in use, but if exposed even when not in use, a certain degree of deterioration is inevitable even if a highly durable material is selected. . The timing of using the roof safety member 1 is generally only for a limited time such as inspection / repair of the roof or replacement work, and most of the other times are not used. Accordingly, the roof safety member 1 according to the present invention has a bottom side surface of the roof tile 71 and a top side rear surface of the top roof 72 that is placed one step above the roof tile when not in use. In this case, the connecting portion 4 is stored in a storage space 74 including a ridge-side portion and a head in the installed state. Specifically, the storage space 74 is an overlapping portion of the roof tiles 71, and the back surface on the head side of the roof tiles that are installed most recently and the bottom side surface of the roof tiles that are placed one step below. Is to be stored in. In particular, when the roofing material is clay tile, a relatively wide space exists in the overlapping portion between the roof tiles, and on the other hand, it is a stable roofing material that has excellent durability and does not deform or collapse over a long period of time. The storage space is almost unchanged. Therefore, by storing the connecting portion 4 exposed to the roof surface in the storage space, the connecting portion 4 is not directly exposed and the progress of deterioration can be largely suppressed. In addition, the space in which actual storage is possible is not only the overlap of the tiles as described above, but also the range surrounded by the field ground 61 continuous with the storage space 74, the bottom end surface of the roof tile 71, and the back surface of the upper roof tile 72. (Space) can also be included.

  A storage position mark 43 is connected to the loop 41 of the connecting portion 4 as shown in FIG. As described above, in the state where the connecting portion is stored in the storage space 74, it may not be noticeable in appearance, but when trying to take out the connecting portion 4 when necessary, where is the roof tile storing the connecting portion 4 just by looking at the entire roof? I can't determine if it exists. Therefore, the storage position mark 43 is connected to the loop 41 on the side exposed on the tile surface during use, and is always exposed on the surface of the roof tile 71. That is, even when the connecting portion 4 is stored in the storage space 74, the storage position of the connecting portion can be visually confirmed by the storage position mark that is always exposed. Further, since the storage position mark is small with respect to the connecting portion 4, it does not stand out in appearance. The storage position mark may be attached only to the side exposed to the roof tile surface of the two loops 41 in the connecting portion 4, and it is natural that the other loop has no place for attachment. Therefore, it is unnecessary. Since the storage position mark is a member that does not directly affect the safety, which is the original function of the roof safety member 1, the storage position mark may be always exposed.

As shown in FIGS. 16 to 17 c, the storage position mark is preferably a wire material or a plate material, and is made of the same material as the fixing portion 2 and the connecting portion 4 made of stainless steel or the like. In addition, the storage position mark 43 may be connected to the connecting portion in advance, or may be attached to the loop 41 later at the installation site of the roof safety member 1 (in the construction examples to be described later, an example attached in advance). Is shown). Furthermore, by being connected to the loop 41 in a movable state, the degree of freedom increases between the connecting portion 4 (or the loop 41) and the storage position mark 43, and the storage space 74 of the connecting portion 4 is moved to. It becomes easy to put in and out regardless of the storage state. The length of the storage position mark 43 is preferably about 20 mm to 80 mm from the point where it is connected to one end of the connecting part 4 to the tip most drooped to the eaves side, particularly about 50 mm. The point is that the storage position mark 43 is connected to the loop 41 so that the storage location of the connection portion 4 is not conspicuous and the position can be confirmed.

In addition, by providing a pull-out claw 44 at the end of the storage position mark that is not connected to the loop 41, a finger is used to expose the connection portion 4 stored in the storage space 74 to the roof surface. The connection part can be easily and smoothly taken out by pinching with ease. The shape of the storage position mark 43 is preferably, for example, a protrusion or a hook-like shape (for example, FIG. 17 c), is a shape that can be hooked with a finger, and there is no possibility of mistaking the carabiner 83. In addition, since the storage position mark is sandwiched between tiles on the side connected to the loop, the storage position mark does not flutter on the roofing material in strong winds, and no noise is generated due to the roof material and the storage position mark colliding. .

[Construction Example 1]
As the first embodiment, the roof safety member 1 is composed of the fixed portion 2, the locking portion 3, and the connecting portion 4 as shown in FIG. 6, and the shape of the locking portion 3 is the above-described folding pattern. The second shape having a substantially U shape in cross-sectional view is provided with a warping claw 34 as shown in FIG. The construction procedure will be described in detail with reference to FIGS. The roof safety member 1 is attached to a general roof having a ridge (particularly a large ridge) such as a gable roof or a dormitory roof tiled with clay tiles.

  After finishing the upper building and the roof is formed with the field board, a waterproof roofing (not shown) is put up. Next, as shown in FIG. 18, the roof safety member 1 of the present invention is constructed in a large building. Here, the attachment interval of the safety member for the roof will be described, and there is no particular limitation. When the roof safety member is used as a substitute for the conventional ridge bracket, a part of the conventional ridge bracket may be replaced with the roof safety member and arranged in a balanced manner. In other words, if the roof safety member has a shape that does not play the same role as the ridge bracket, it can be attached to the desired position with a certain degree of balance and attachment position regardless of the arrangement of the conventional ridge bracket. If the roof safety member also needs to play the role of a conventional ridge bracket, the roof safety member may be constructed in place of the ridge bracket that is originally attached. Examples of the attachment interval include 910 mm, 600 mm, and 455 mm, but are not necessarily limited to this, and can be determined as appropriate in consideration of the length of the large ridge of the roof and the balance with other ridge fittings. In addition, if it is attached on a rafter (not shown) that constitutes the roof, the field plate and rafter are sufficiently fixed with screws, which is a more desirable state.

  The fixing member 2 is fixed to the field ground 61 by straddling the roof safety member 1 over the main building, and then the loop 41 at one end of the connecting portion 4 is hooked on the locking portion 3 as shown in FIG. At this time, since the warping claw 34 of the locking part is provided so as to warp in the direction opposite to the leg part, the entrance of the opening 32 becomes wide and the connecting part 4 is clogged with the entrance of the locking part 3. It can be hooked smoothly without any problems. When the hook is completed, it can withstand a load in the eaves direction to a certain extent. However, as shown in FIG. To do. In this fixing, since the roof safety member 1 is generally formed of a thin plate, the opening 32 having a substantially U shape in cross section of the locking portion 3 is slightly deformed by the force applied when the screw 22 or the like is driven. Accordingly, the opening 32 can be closed. Therefore, the connection part 4 can be made detachable from the connection part 4 as long as the caulking 42 part is unraveled, the loop 41 is broken, or the screw 22 or the like does not come out of the field plate 61.

  When the installation of the safety member 1 for the roof is completed, a vertical residue (not shown) is applied if necessary, and subsequently, a crosspiece 62 is applied in accordance with the working length of the roof tile 71 as shown in FIG. Furthermore, the ridgeline 62 at the ridge is constructed on the safety member 1 for roof. At this time, if the locking portion 3 and the crosspiece 62 interfere with each other, the portion of the crosspiece 62 that interferes with the locking portion 3 is cut out or is avoided so as not to interfere with the locking portion 3. . This completes the construction of the groundwork. In addition, in the above process, if the locking portion 3 is attached first, there is a risk that the connecting portion 4 will be laid under the construction of the pier. May be.

  When the groundwork is completed as described above, the roof tiles 71 are sequentially spread on the field surface 61. As shown in FIG. 22, the roof tiles are lifted up to the vicinity of the building without any difference from the conventional construction, but when the roof tile one step lower than the building is rolled up, there is a slight difference between the construction and the conventional construction. Generally, since the roof tile 71 comes directly above the connecting portion 4 hanging from the field ground 61, the position of the connecting portion 4 is adjusted to be on the front side of the roof tile 71, and as shown in FIG. The side that is not locked and the side that is not locked is protruded from the surface of the roof tile 71, and the upper roof tile 72 near the ridge is further spread. At this time, if the connecting portion 4 is in the gap in the width direction of the roof tile, it can be constructed as it is without shaving the roof tile depending on the case. When the gap between the roof tiles is wide, the lower part on the head side of the upper roof tile 72 can be slightly shaved as necessary to secure a space for the locking portion. The point is that there is a work that does not exist in the conventional roof tiles, the operation of putting the connecting portion 4 on the surface of the roof tile 71, and a measure not to generate a gap that does not occur in the original roof tile when the connecting portion is exposed on the roof tile surface. That's what it means.

  When the upper roof 72 is finished, the remaining work steps may be the same as before. As the finishing of the ridge, for example, as shown in FIG. 24 (not shown the ridge bracket), the ridge rafter 64 is fixed to the receiving portion 52, and the ridge is waterproofed using a Nanban plaster 63 or the like at the ridge, If the roof tile 73 is rolled and fixed to the roof rafter 64, the construction of the roof is completed. Finally, the connecting portion 4 is stored in the storage space 74, and a part of the storage position mark 43 is exposed on the tile surface. In addition, when the building is housed with half-finished roof tiles, the connecting portion may be exposed from the gap between the roof tile and the half-finished roof tile (upper roof tile) as shown in FIG. Further, in this case, the length of the connecting portion may be set shorter than the length of the connecting portion in the case of the real thing.

By the construction as described above, the fixing portion 2 of the roof safety member 1 is directly fixed to the roof surface, and the locking portion 3 and the connecting portion 4 are accommodated inside the roof surface and the upper roof tile 72 and the roof tile 73. , Never exposed. Moreover, since only the storage position mark is exposed on the tile surface, it does not stand out in appearance on the roof. After completion of the construction, the storage position mark 43 can be used to confirm the storage position of the connecting portion 4 when it is next used.

[Construction Example 2]
As a second embodiment, a construction method for locking the connecting portion 4 to the locking space 27 will be described in detail with reference to FIGS. The roof safety member 1 in this construction example 2 includes a fixing portion 2, a connecting portion 4, and a purlin receiving portion 5 as shown in FIGS. 8 and 14, and the connecting portion 4 is engaged with the locking space 27. Use one that has stopped. Other conditions and the like are the same as in the construction example 1. In addition, the safety member 1 for roof in this construction example has a function for supporting a purlin such as a so-called ridge metal fitting or a strong ridge, and a safety work connected to a carabiner 83 of the safety belt 81 worn by the operator 8 or the like. It combines the function of a member for use. That is, the above-described two functions can be performed simultaneously with one member.

  First, as shown in FIG. 26, the loop 41 of the connecting portion 4 is passed through the leg portion 28 of the fixed portion 2 to reach the locking space 27. As described above, the roof safety member 1 according to the present invention is rotationally symmetric about the central portion of the support portion 51, so that the loop 41 similarly reaches the locking space 27 on the other leg portion 28. (FIG. 27). Further, the fixing portion 2 is temporarily placed at a desired position of the field ground 61 so that the connecting portion 4 is not sandwiched between the leg portion 28 and the field plate 61, and the screw 22 is fastened to the nail hole 21 to fix the fixing portion 2. Is fixed to the field ground 61 (FIG. 28). At this time, it is preferable to confirm whether or not the connecting portion 4 is movable in the locking space.

  Subsequently, as shown in FIG. 29, the piers 62 are constructed in the same manner as in the construction example 1, and the roof tiles are staggered or streaked from the eaves side, leaving two ridges. As shown in the construction example 1, when the second stage is rolled from the ridge, it is whispered while adjusting the position of the connecting portion so that the existing connecting portion 4 is surely exposed on the surface of the roof tile 71 (FIG. 30). In addition, the upper roof tile 72 near the building is sown. At this time, when spreading the roof tile where the connecting portion 4 is located, an adjustment is made so that the connecting portion 4 can be stored in the storage space 74 (FIG. 31). Specifically, after temporarily laying up to the roof tile at the side of the building, the position of the roof tile may be adjusted after the connecting portion 4 is stored in the storage space 74, or the connecting portion 4 is deformed into an S-shape or the like. However, the roof tiles may be sown and stored. The most important thing is not to put the storage position mark 43 together in the storage space at the time of construction, but to surely expose it to the surface of the roof tile so that the storage position can be confirmed from the appearance of the entire roof.

  Once the flat part of the roof is completed, as in the first embodiment, the purlin 64 is attached to the purlin receiving part 5 or the purlin 64 is attached to the purlin receiving part 5 in advance and the ridge is finished before construction. It is completed (for example, FIG. 32). When the building is half-finished, it may be stored using a short connecting portion 4 as shown in FIG. 33. However, the length of the connecting portion 4 is stored when not in use. A long one may be used. After completion of the construction, it is desirable to confirm whether the connecting portion 4 can be taken out and stored from the storage space 74 using the storage position mark 43. In this construction example 2, it is only necessary to add the connection part 4 and adjust the position, compared with the conventional construction work that used only a so-called strong building such as a building bracket for the building. It is possible to construct a member having both the function of the strong building and the safety function for the worker without greatly degrading the performance.

[Construction Example 3]
As a third example, the construction method is not the construction method in which the connecting portion 4 is locked to the locking space 27 as in the construction example 2, but one end of the loop 41 of the connecting portion is locked to the bent portion 24 and the other end is fixed. The construction method hung on the leg part opposite to the leg part 28 constituting the locked bent part 24 will be described with reference to FIGS. Different from the second embodiment in that the connecting portion is locked to the bent portion and fixed to the base plate, the subsequent procedure is the same.

  As shown in FIG. 34, the loop 42 of the connecting portion is passed from the tip of the leg portion, and at this time, the caulking portion is passed while maintaining a state below the leg portion. Alternatively, as in the construction example 2, the loop 42 is passed through the leg portion while keeping the crimped portion above the leg portion to reach the locking space, and then the loop on the other end side is supported by the support portion 51. May be reversed in the horizontal direction around the axis so as to come to the leg side opposite to the leg part constituting the bent part where the loop on the other end side is locked.

  Then, as shown in FIG. 35, the leg portion 28 constituting the bent portion that locks the loop 41 at one end of the connecting portion 4 to the bent portions 24 on both sides and the loop at the other end of the connecting portion, respectively. The fixing portion 2 is fixed to the base plate 61 so as not to sandwich the connecting portion 4 as shown in FIG. Thereafter, as shown in FIG. 37, the building part is completed as in the second construction example. In this embodiment, since the loop of the connecting portion 4 is directly locked to the bent portion 24, the fixing portion and the base plate are used rather than the loop 42 of the connecting portion 4 being locked to the locking space as in the construction example 2. In such a case, the connecting portion can be more securely and safely locked to the fixed portion. Furthermore, as in the case of a conventional ridge bracket, the ridge tile can be fixed by supporting and fixing the ridge tree.

[Storage structure of the connecting part when not in use or required]
Here, with reference to FIGS. 38 to 40, a method of taking out and storing the connecting portion 4 will be described. Here, it is assumed that the roof safety member 1 and the roof tile are both in a construction completed state, and the connecting portion 4 is stored in the storage space 74. After climbing the roof, when going up to the roof for periodic inspections or repairs, it may be dangerous for the worker to work without any connection to any fixed object on the roof because there is a case where only a stepladder etc. is built without building a scaffold. . For this reason, the carabiner 83 or the like of the safety belt 81 worn by the operator himself / herself is connected to the roof safety member 1 fixed to the roof ridge, and the safety of the operator is ensured.

First, as shown in FIG. 38, the storage position mark 43 is searched from the roofed roof surface, and the storage location of the connecting portion 4 is registered. When the connecting portion 4 is stored, the storage position mark 43 is exposed on the surface of the roof tile 71. Subsequently, the drawer pawl 44 of the storage position mark 43 is grasped and pulled out (naturally, the place to grab is not limited to the drawer pawl, but considers ease of taking out). Normally, (gap portion where桟瓦to each other are overlapped in particular vertical position) gap桟瓦that constitute the storage space 74 only because of the order 0～3Mm, pulls in One simply pulled out pawl 44 Man Then, it is difficult to pull the connecting portion 4 to the roof surface. Therefore, as shown in FIG. 39, the problem is solved by artificially providing a gap that allows the connecting portion 4 to be taken out by slightly lifting the upper roof tile 72 using a flat-pointed tool such as a flat-blade screwdriver. it can. Then, when all the connecting portions 4 are taken out as shown in FIG. 40, the carabiner 83 connected to the safety belt 81 worn by the operator 8 is connected to the loop 41. Thereby, the connection part 4 can be taken out when necessary, and operations such as inspection and repair on the roof can be performed safely.

  After the work on the roof is finished, when the connecting portion 4 is not used, the connecting portion 4 is stored in the storage space 74 by a procedure reverse to the method of taking out the connecting portion 4 described above. Specifically, when the connection portion 4 is pushed from the roof surface side to the storage space 74 side by pinching the loop 41 or the storage position mark 43, the connection portion has flexibility, so that The storage space 74 can be stored while drawing a curve in the left-right direction. The storage space 74 is generally continuous with a portion constituted by the roof tiles 71 adjacent to each other in the width direction and the upper roof tile 72, or the bottom edge surface of the roof tile 71, the field plate, and the upper roof tile 72 that is placed one step higher. Since there is also a storage space in the place composed of the back surface, the connecting part 4 can be kept inside the roof without exceeding the storage capacity in the storage space (mainly the back surface of the roof tile that has been tiled with the field floor) And can enter the space). Finally, when all of the connecting portions 4 are stored in the storage space 74 while leaving a part of the storage position mark 43 on the roof surface, the storage is completed. It is the same for the connecting portion 4 to be stored in the storage space 74 after the construction of the roof safety member 1.

  As described above, after the roof safety member 1 is attached, the roof safety member 1 is stored in the storage space 74 in the roof tile and is not exposed to the tile surface. In the case of not in use), only the storage position mark 43 is exposed on the roof surface, so that the effect of making it less noticeable than when a part of the connecting portion 4 is exposed is exhibited.

  Although the structure and construction method of the safety member 1 for roof of the present invention and the method for storing and taking out the connecting portion 4 have been specifically described, the present invention is not limited to the above-mentioned preferred examples, and the fundamental technical concept thereof. It can change suitably in the range which does not deviate from. The technical idea of the present invention is generally characterized in that important parts are not exposed when not needed. As another structural example of the safety member 1 for a roof, for example, in the state where the purlin receiving portion 5 is not provided, and the mountain-shaped top portion 23 of the fixing portion 2 has a hinge structure, the angle of the right and left fixing portions 2 can be freely set. It can be changed and can handle any gradient with a single member. In addition, it is possible to cope with the case where the two roof surfaces forming the ridge have different inclination angles. A single-flow roof is also possible (for example, FIG. 41). In addition, if the length of the locking part 3 is set to about two types, the roof tiles at the building will be half-finished tiles (in this case, when the size of the building at the edge of the building is too large to fit, The connecting portion 4 does not appear greatly on the appearance when it is stored with a short cut tile. Furthermore, by shortening one end of the fixed portion 2 and changing the length of the left and right sides, the flow of the roof is extremely short on one side of the gable roof. For example, the flow length is about one piece of roof tile. Etc.). In addition, SUS316 is desirable for the material of the connecting portion. However, as long as durability is sufficiently ensured even if it is made of SUS304 or other materials (not limited to metal) by technical improvement, the cost is lowered and appropriate. The material is changed.

  In the work on the roof, the technical idea of “accommodating” the connecting portion for locking the lifeline as a mounting bracket for a safety belt (lifeline) used for ensuring the safety of the work is provided. Therefore, it can be widely used as a lifeline mounting bracket for various work as well as the roof.
