Description

  The present invention relates to a roof safety member for connecting a safety belt or the like so as to be constructed on a roof ridge and to be able to safely perform work on the roof.

  In recent years, there has been a tendency to extend the life of houses and the like, and accordingly, opportunities for carrying out regular inspections and repairs on the roof have increased. In addition, there are many opportunities to work on the roof, such as installing solar power generation devices and solar water heaters that are effective in reducing environmental impact, repairing antennas, and lowering the roof in heavy snow areas. . On the other hand, the roof is generally inclined and has many high places, and it is difficult to work on the roof with the danger that it always slides down. Sex is emphasized. Therefore, a temporary scaffold may be installed to perform work at a high altitude, but there are many cases where the scaffold is not installed or cannot be installed when there is a need for immediacy such as a small area, a small amount of work, or disaster recovery. It was.

  Various things and means are considered as safety measures for the roof. As an example, according to the invention of Patent Document 1, as shown in FIG. 28, a safety band attachment 8 used for locking a safety band worn by an operator when working on a roof, Each side part is placed on the top edge of the tile near the ridge in the section, and is formed so as to cover the ridge, and is attached to the roof together with the roof tile by a roof tile. A hook portion 83 projecting upward from the upper surface of each support portion 82 of the attachment main body portion so that a connector attached to a safety belt worn by an operator is locked. There is a configuration in which the attachment main body portion is covered with a ridge wrap 84 except for the side portion to which the hook portion is attached.

  With this configuration, the roof and the roof are firmly attached without impairing the design and structure of the roof and the ridge. Moreover, since the tiles in the roof portion are not damaged, an effect that there is no risk of rain leakage or the like in the house is exhibited.

  Similarly, there is a safety member for roof described in Patent Document 2. According to the invention described in Patent Document 2, a pair of wooden purlins (not shown) are mounted in the longitudinal direction of the ridge through the ridge top portion 92 on the ridge portion of the roof covered with the roof tile 91 as shown in FIG. At the same time, the wrapping 93 is attached so as to cover the purlin, and the safety metal fitting 9 having the hook portions 94 on both ends and extending in the width direction of the wrapping is placed on the wrapping, and the safety wrapping is carried out from the safety metal fitting. There is a configuration characterized in that a fixing tool 95 such as a screw or a nail is driven into the purlin and a safety fitting is attached with the fixing tool.

  With this configuration, safety metal fittings can be attached to the roof ridge using a purlin, allowing safer work in the roof ridge that is safer than the eaves, and on the wrapping in the ridge. It can be installed just by driving in the fixing tool along the way, and it is easy to install the safety bracket. In addition, since the safety bracket is attached to the roof ridge, it can be left inconspicuously even if it is not removed after the roof work is completed, so there is no need to remove the safety bracket and the next roof work Demonstrate that it can be used.

  However, the invention in Patent Document 1 has room for further improvement. First, as a major premise, parts for safely performing work on the roof are the parts that are most important for locking with the worker's safety belt and the like, and are the parts that influence the safety of the work. However, in patent document 1, although the attachment main-body part currently fixed to the roof surface with the roof tile together with the roof material is covered with the wrapping except the hook part, the hook part is not covered with the wrapping material. Therefore, the hook portion is likely to deteriorate. That is, since the hook portion connected to the safety belt is always exposed, it is directly affected by the outdoor environment such as solar radiation, acid rain, wind and snow, and dust. As a result, the deterioration of the connection portion progresses at a relatively early stage, and depending on the deterioration, in the worst case, the hook portion may break during use and the original function of protecting the roof operator may not be achieved. . Further, in the invention described in Patent Document 2, there is the same fear, and since the plate-like hook portion always protrudes from the ridge wrap to the eaves side slightly upward, it is conspicuous in the appearance of the roof, and the design is not the best. There was a problem.

  In view of the above, the problem of the present invention is that the design is good, and when not in use, the connecting part is present on the roof so that it is not directly exposed to the outdoor environment. An object of the present invention is to provide a roof safety member that is exposed on the surface and is used for safety measures during roof work.

  In order to solve the above-described problems, the roof safety member of the present invention is a roof ridge in which a headboard is fixed to a roof top of the roof on which the roofing material is spread, and the headboard is covered and fixed with a wrapping material. A safety member for a roof for safely performing work on a roof, which is attached to a section, and is connected to a main body metal part fixed at a ridge part, a fixing material for fixing the main body metal part, and the main body metal part. The main body metal fitting and the connection part are accommodated in a storage space when not in use.

  By adopting this configuration, most of the period when the roof safety member is not used is not directly exposed to the outdoor environment, so it is possible to suppress the aging deterioration of the metal fittings and connecting parts that are responsible for the safety function. It is possible to use a roof safety member that can prolong their life and maintain safety performance for a long period of time.

In the storage space described above, a wing wrap material and a headboard in a general ridge storage are partially omitted, and the storage space is used as the storage space. Specifically, it is comprised by the cover body and the one part cut-off part provided in the coping . In this configuration, the cover member covers the portion of the ridge wrapping adjacent the ridge direction, is construction to the lid to ridge wrapping the edge is cut around the storage space.

  A metal frame made of a thin plate is installed in a part of the headboard constituting the storage space, and a screw hole is provided in the metal frame. This screw hole matches the position of the through hole provided in the cover body, and the two members of the metal frame and the cover body can be fixed integrally by using a screw or the like from the through hole. By adopting this configuration, if the roof safety member is attached to the ridge in advance on the roof, it can be prepared in the roof ridge when stored in the storage space when not in use, and fixed when in use. The connecting part can be taken out by loosening the screw or the like and removing the cover body. In addition, since the cover body is separate from the wrapping material, the presence of the cover body itself can be seen in the appearance, but by providing the cover body with a storage position mark, the roof safety member exists in the roof ridge. It is also possible to make it easier to confirm this.

  As a structure that enhances waterproofness and workability of the safety member for roofs, a waterproof sheet is fixed in a state that can be repeatedly opened and closed (turned and returned) to one side of the headboard adjacent to the storage space, and at least the waterproof sheet is stored A structure that covers the space is adopted. By adopting that configuration, it is possible to prevent the intrusion of rainwater etc. into the roof from the part where the roof safety member is attached, and to exhibit more complete waterproof performance in combination with the water-stopping member described above it can.

  Here, since both ends of the connecting portion of the present invention are configured by loops, and one end of the connecting portion is locked to the main body fitting, the locking to the main body fitting and the safety band are locked by one connecting portion. It can be performed. In other words, if there is a carabiner or the like of a safety belt, the roof surface and the operator can be connected via the connecting portion attached to the main body metal fitting.

  The roof safety member of the present invention does not impair the design of the roof, it can be made difficult to deteriorate while being attached to the roof ridge, so it can be used when needed for a long period of time. And the effect that the safety member for roofs holding sufficient intensity | strength can be provided is exhibited.

  Hereinafter, the basic configuration and examples of the roof safety member 1 of the present invention will be described in detail. The roof material in the present invention is exemplified by a particularly thin roof material such as a decorative slate or sheet metal.

  First, the structure of the roof safety member of the present invention will be described. The structure which becomes the nucleus of the safety member for roofs of this invention is mainly comprised by the main body metal fitting 2 and the connection part 3. FIG. In addition, the building in this application shall represent both a land building (large building) and a corner building unless otherwise indicated.

  As shown in FIG. 1 to FIG. 4, the main body 2 has a leg portion 21 having a substantially chevron shape in front view so that it can be fixed across two roof surfaces constituting the ridge core (FIG. 2). A leg portion fixed to the base plate 73 and a rising surface 23 that is raised via the bent portion 22 are formed at the upper end of the leg portion. The two leg portions 21 fixed to the two roof surfaces are not collinear with respect to the ridge core, and a connecting plate 24 is provided so as to connect the two rising surfaces 23 to each other. Two leg portions 21 are integrated by a connecting plate 24. That is, it is formed by punching and bending a single steel plate. Here, the connecting plate 24 is not provided at the full height with respect to the rising surface 23, and the lower end side (leg side) is shorter than the rising surface 23 by about 3 mm to 10 mm. This is a space 27 in which one end of the connecting portion can be hooked on the metal fitting (FIGS. 2 and 4). In other words, this space is configured by being surrounded by the base plate 73, the rising surface 23, and the lower end of the connecting plate 24 in a state where the main body fitting is fixed to the ridge, and at least two connecting portions 3 described later are provided. You can get stuck. As shown in FIGS. 1 and 3, the main body fitting 2 as a whole is, for example, a substantially rotationally symmetric body with the center of the connecting plate as the vertical axis, and the leg portions 21 are staggered across the ridge core. It is fixed to the roof surface (the upper side is substantially S-shaped or substantially inverted S-shaped).

  The leg portion 21 of the main metal fitting is provided with several nail holes 25 for fixing the main metal fitting 2 to a field plate 73 (not shown, but also includes a rafter supporting the field plate in this case). Yes. As an example, about 2 to 6 nail holes are provided in each leg, and two or more rows are provided in the length direction of the legs. And it is desirable to fix at least two leg portions of the nail hole. By arranging the nail holes in two or more rows or setting a large number of nail holes 25, for reasons of the roof base, it cannot be fastened, or the nail holes are not suitable for fastening. However, since there is an alternative nail hole when fixing the metal fittings, it is easy to be flexible. In addition, it is desirable to use a screw as a fixing material used for fixing the main body metal fitting 2, and the screw having a larger number of threads per unit length is further provided to the head as much as possible. It is more preferable (so-called full screw) because it has excellent fastening strength to the base plate 73 and rafters.

Further, the thickness of the main body metal fitting 2 is preferably about 1.0 to 2.0 mm. If it is a fixing method that fixes directly from the top of the roofing material 74 toward the base plate 73, it is not necessary to worry about the floating of the roofing material due to the thickness of the main body bracket, but the safety member for roofing is attached from above the roofing material. If attached, the fixing material 3 will penetrate the roof material 74, and there is anxiety in a waterproof surface. Therefore, in the present invention, a method of directly fixing to the base plate 73 is adopted. At this time, if the roof safety member 1 is constructed below the roof material 74, a slight step due to the thickness of the main body metal fitting is produced in the case of a thin roof material such as a decorative slate. In this state, if the roofing material is constructed from above, there is a risk of cracking when a load is applied. On the other hand, there is no problem if the plate width of the leg portion and the rising surface is about 20 to 40 mm, but there is no particular limitation regarding the widening, and an optimal plate width is appropriately selected in consideration of strength and cost. adopt. The length of the leg is also preferably about 50 to 100 mm, particularly about 70 mm, but may be a length that can sufficiently secure the base plate 73.

  Further, as shown in FIG. 2 and the like, a rib 26 protrudes from a bent portion 22 constituted by the leg portion 21 and the rising surface 23. The shape of the rib is such that the bent portion 22 protrudes outward (approximately on the acute angle side of the corner formed by the leg portion 21 and the rising surface 23) when the main body 1 is fixed to the base plate 73. It is shaped like an arc. By this convex arc-shaped rib, the bent portion 22 has a three-dimensional shape rather than a mere bent thin plate, and can exhibit sufficient strength such that it is less likely to break when the connecting portion is pulled.

  Next, the structure of the connection part 3 is explained in full detail. As shown in FIG. 5, the basic configuration of the connecting portion 3 of the present invention is composed of a wire (wire). By adopting a flexible wire, the storage in the storage space S and the removal from the storage space are performed smoothly, and when moving to various places on the roof surface during work on the roof, Since the trunk | drum 33 bends toward the moving direction, there also exists an advantage that an excessive load is not applied to a main body metal fitting or the connection part itself.

  Further, both ends of the connecting portion 3 form a loop 31 closed by caulking 32 (which can be ice-price processing), one end is locked to the body fitting 2, and the other end is stored in the storage space S when not in use. However, when it is used, it is exposed on the surface of the roofing material 74 and can be connected to a carabiner or the like of a safety belt worn by an operator on the roof. Further, in the connecting portion 3 of the present invention, the size (inner diameter) of the loop 31 is at least larger than the width of the leg portion 21 of the main body metal, and the thickness of the connecting portion 3 is, for example, 2.0 mm to 5.0 mm. The degree is good, and in particular, about 3.0 mm to 4.0 mm is desirable. The length between the loops at both ends of the connecting portion (the length of the body portion 33) may be such that at least the loop 31 on the other end side is exposed in the entire range from the storage space S when in use. It is good that it is largely exposed on the roofing material. For example, the body length is about 100 mm to 300 mm. Here, since the connecting portion 3 is taken out during use and stored in the storage space S when not in use, the length is not particularly limited as long as the length of the connecting portion 3 is at least, but the cost, construction surface, It is desirable to adopt the best length from the viewpoint of storage workability.

  And the material of the connection part 3 employ | adopts the thing made from SUS316 which has high durability as an example in consideration that the safety | security of the worker on a roof is the most important performance. The connecting part 3 is basically stored in the storage space S as described above, and is exposed when the roof is used for maintenance or for installation work such as solar panels, solar water heaters, and antennas on the roof. Although it is limited, even if it is stored in the storage space when not in use, it is not completely cut off from the outdoor environment, and it naturally touches moisture and outside air. Therefore, in the connection part of the present invention, safety is ensured over a long period of time by selecting a material made of SUS316 that is more durable than a general material of SUS304. It was confirmed that the product made of SUS304 was rusted because the wire itself became magnetic due to the processing when 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, no abnormality such as red rust was observed in SUS316. For this reason, it is desirable to select SUS316 as the material of the connecting portion because it can ensure stable quality for a long period of time.

Roof safety member 1 of the present invention, ridge portion by the connecting portion 3 and the metallic body member 2 as described above is configured, by fixing the roofboard 7 3 Toitadaki part using a fixed member, on the roof Safe work is possible. Subsequently, the metal frame 4, the waterproof sheet 51, and the cover body 6 that constitute the peripheral portion of the roof safety member 1 are used to exhibit the effect of being stored in the storage space S when not in use and being taken out from the storage space S when in use. Is described below.

  In a ridge structure of a thin roof material such as a decorative slate, a headboard (roof headboard) 71 is generally constructed in the vicinity of the roof top portion of the roof material so that the wrapping material 72 can be fixed on the roof material 74. . The headboard is constructed so as to be paired with the same length as that of the roof ridgeline and straddling the ridgeline, and the fixing position or size of the headboard 71 is determined in accordance with the width dimension of the wrapping material 72. Therefore, only a small gap is generated in the ridge after the ridge wrapping material is fixed to the headboard, and there is no space for storing the connecting portion 3. Therefore, with respect to the headboard 71 that is constructed over substantially the entire length of the ridge, a cutout portion is provided by partially cutting out the headboard so that the storage space S of the connecting portion 3 can be secured. Instead, a configuration in which the metal frame 4 is fixed is adopted.

  As shown in FIGS. 6 to 9A, the metal frame 4 is formed by punching and bending a single steel plate, and has a “L” shape or an “inverted L” shape in cross section. . Of the two surfaces, the surface that contacts the roof material 74 is the frame base 41, which is wide and has a substantially “U” shape in a plan view in which a part including one side becomes a notch 45. Further, a finding surface 42 that rises perpendicularly to the frame base 41 is configured from the side facing the side cut by the notch 45 of the frame base. The frame base is provided with a base nail hole 43 so that it can be fixed to a roofing material or a ground plate using a fixing material, and a cover body 6 that covers the metal frame 4 from above is provided on the finding surface 42. A screw hole 44 is provided for fixing. Since this screw hole is provided in a thin metal frame obtained by processing a steel plate having a thickness of about 1 mm to 2 mm, it is formed by burring so as to ensure the length of the threaded portion as long as possible. By providing the screw holes in the mounting surface as described above, when removing the cover body from the metal frame, it becomes difficult to damage the screw holes even if the screw and bolt tightening work is repeated. As compared with the case where screw fixing is repeatedly performed on wood such as, a fixed fixing force can be secured over a long period of time. The headboard may be a metal frame itself instead of wood, and a screw hole may be provided in the metal frame portion only where the cover body is attached.

  The width of the metal base (flow direction) of the metal frame is substantially the same as that of the headboard, and the length is at least sufficiently larger than the plate width of the main body fitting, so that all the connecting portions can be accommodated. As an example, the width of the frame base is preferably about 50 mm to 120 mm, and the length is preferably about 100 mm to 300 mm, but can be appropriately selected in consideration of the length of the connecting portion and the cost of the metal frame. Moreover, the height of a finding surface should just be substantially the same as the height (thickness) of a headboard, and about 15 mm is good as an example.

  Since the metal frame 4 is formed of a thin plate having a substantially L-shaped or substantially inverted L-shaped cross section as described above, the metal frame 4 has a smaller cross-sectional area than the adjacent headboard 71 in the ridge core direction, and on one side ( The eaves side. When the ridge wrapping material 72 and the metal frame 4 are covered with the cover body 6 from above, the ridge wrapping material 72 covers the portion of the headboard with almost no gap, but when the metal frame portion is covered with the cover body from above, Since the cross-sectional area is small compared to the headboard, a lot of space remains. In other words, place the metal frame around the site where the metal fittings were installed, adjust the dimensions so that the height and width of the metal frame are the same as the headboard, and place the metal frame By constructing the headboard on the top of the building other than, it looks like there is a headboard for the entire length of the top of the building, and the metal frame part is a space (storage space S by fixing the building wrapping material and the cover body described later. ), The connecting portion can be stored.

  As shown in FIG. 9B, the shape of the metal frame is a configuration in which an upper surface portion 46 that is further folded back toward the frame base 41 side from the upper end of the finding surface 42 is provided (substantially U-shaped in a cross-sectional view). Good to be. The upper surface portion 46 prevents rainwater from entering through the screw holes 65 of the cover body more reliably, and stores the connection portion 3 by bending it (winding in a tangle) when the connection portion 3 is stored in the storage space S. It can be used for the purpose of restraining or catching against the strong restoring force of the connecting portion that works when making it. Therefore, the storage workability of the connecting portion 3 to the storage space S can be improved by further providing the upper surface portion from the upper end of the finding surface 42.

  As shown in FIG. 10, the waterproof sheet 51 covers the connection portion 3 from above after being accommodated in the metal frame 4, and further functions as a secondary waterproof of the cover body 6 covered from above. The waterproof sheet is made of a non-woven fabric as an example, and not only does not allow water that has entered from between a cover body and a wrapping material, which will be described later, to pass through the connecting portion 3 when the roof safety member 1 is used. It is desirable to have such a property that it is temporarily turned so that it can be taken out from the storage space S and can be returned to its original state after use. The term “flexible” as used herein refers to a property such that when the waterproof sheet 51 is turned, a crease is formed around the fixed portion, and then the crease is not torn by repeating return and turning. A specific use state of the waterproof sheet is that after the metal frame 4 and the headboard 71 are installed on the ridge 7, the waterproof sheet 5 is fixed to only one side of the headboard 71 adjacent to the metal frame 4 in the ridge core direction. 4 and the other side 71 are not fixed but are covered from above. When the connecting portion 3 is taken out from the storage space S, the other side is turned to one side so that the connecting portion 3 can be easily taken out from the storage space S. In other words, the waterproof sheet 51 is temporarily turned over in accordance with the occasion of taking out the connecting portion 3, but is not completely removed, and the metal is used in accordance with the opportunity for storing the connecting portion in the storage position. The frame and the other side can be covered, and they can be repeated.

  The width of the waterproof sheet 51 is approximately the same as the width of the eaves side edge of the headboard 71 installed in the ridge 7 to the side edge of the eaves of the opposite side across the core, and is slightly wider than that. It is set so as not to protrude from the material 72 and the cover body 6. In addition, the length covers the entire metal frame part, and the side fixed to the headboard is polymerized by 30 mm to 100 mm on the wing wrapping material, and the side not fixed is polymerized about 30 mm to 100 mm on the wing wrapping material. A length that does not protrude is desirable. The fixing of the waterproof sheet to the headboard is, for example, stapling using a tool such as a tucker as in the method of fixing the underlaying material of the roof.

  As shown in FIGS. 11 to 13, the basic structure of the cover body 6 is constructed on the roof ridge, and is inclined toward the eaves of the roof from the top of the ridge 61 that is the top of the cover 6. The inclined surface 62 that extends while the side surface 63 is bent vertically downward from the tip of the inclined surface or in the plate thickness direction of the headboard 71, and further inclined toward the eaves direction or the roof material surface direction from the lower end of the side surface portion. It is comprised by the draining part 64 extended in the same direction as a surface direction. The cross-sectional shape of the cover body 6 is substantially the same shape as the wrapping material 72 generally constructed in the ridge, but the width dimension is outside the wrapping material (the end of the wrapping material is Since it is constructed so as to cover, the thickness of the wing wrapping material is increased by one or two sheets (about one size larger than the wing wrapping material) in consideration of the clearance. Moreover, the length of the cover body 6 is good enough to cover at least the waterproof sheet 51, the headboard 71 and the wrapping material 72 at both ends facing the metal frame. The range of polymerization of the cover body with the wrapping material is, for example, about 50 mm to 100 mm at both ends.

  A through hole 65 is provided in the side surface portion 63 of the cover body so as to be fixed to the metal frame 4. Two or more through-holes are provided on one side, and the positions thereof coincide with the positions of the screw holes 44 in a state where the metal frame is fixed to the ridge. In addition, it is desirable that the through hole 65 is formed of a long hole so that the cover body can be aligned with the screw hole 44 of the metal frame even if the position of the cover body is slightly back and forth in the ridgeline direction.

  Further, the cover body 6 is constructed so as to cover both ends of the wrapping material 72 constructed up to the portion where the metal frame 4 exists, but the wing wrapping material 72 and the cover body 6 have substantially the same cross-sectional shape. Some gaps occur because they do not completely coincide when polymerized. Since this gap can cause water intrusion during wind and rain, a water-stopping member 52 (for example, FIG. 25) such as an EPDM sealer is sandwiched between the overlapping portions of the wing wrapping material 72 and the cover body 6, so that rainwater Etc. can be prevented. In particular, when used in a corner building, since there is an inclination, water is likely to enter, particularly on the water side of the overlapped portion of the building wrapping material and the cover body, so that the water-stop member 52 is necessary.

  As another example of the cover body described above, a configuration provided with a storage position mark will be described. The storage position mark is a mark that makes it easy to confirm where on the roof the connecting portion stored in the storage space is inconspicuous in appearance. As shown in FIG. 14, a substantially box-shaped protruding portion that protrudes upward in a front view and has an opening on the lower side is provided. This protrusion may be long in the direction of the ridge core or may have a height in the vertical direction, but the ridge core as in the former is considered in consideration of the design characteristics of the roof and the strength against strong winds. It is desirable to have a shape that is long in the direction (lateral direction) and low in height. If it is such a shape, it will have an appearance that is inferior to the building ventilation members that are generally projected on the ridges in thin roofing materials, without greatly impairing the design, and without providing a cutout in the headboard However, storage space can be secured in the building. As for the size of the protruding portion, for example, the entire ridge top portion 61 and the inclined surface 62 or only the central portion of the ridge top portion and the inclined surface protrudes about 10 mm to 50 mm as compared with a normal cover body. However, these sizes are appropriately determined according to the length of the cover body and the thickness and length of the connecting portion. If the cover body is configured as described above, a part of the cover body protrudes from the wing wrapping material 72, so that the cover body itself serves as a storage position mark. In addition to the display of the storage position mark by shape, the cover body may be changed in color tone with the adjacent building wrapping material 72 or a pattern may be put on the cover body itself.

  Although the structure of the roof safety member 1 of the present invention and the ridge structure using the same have been described above, examples using these structures will be described in detail below, following the construction procedure.

[First embodiment]
As a first example, an example in which the roof safety member 1 of the present invention is attached to a ridge portion 7 of a sloped roof as shown in FIGS. 15 to 23 will be described below. In this example, the construction process to be attached to the ridge part of the roof is shown, and an example in which two connecting parts are attached to one main metal fitting is given. Further, the metal frame 4 employs the example shown in FIG.

  As shown in FIG. 15, an underlaying material is applied to the upper building base plate 73 (roof foundation), and further, as shown in FIG. 16, the loop 31 at one end of the two connecting portions is connected to the main body 2. Pass through the end of each leg 21 and extend the loop at the other end to the opposite side of the leg through the loop at one end, and mount the main body 2 on the top of the ridge 7 while maintaining this state. And fix to the roof base with fixing material. By this fixing, one end of the connecting portion 3 is locked to the space 27 in a state where it cannot be detached, and the other end of the connecting bracket hangs down on the roof surface so that a carabiner or the like of a safety belt can be locked. At this time, the fixing position of the body fitting 2 is preferably such that the rafters are present under the field board because the fastening strength with the fixing material is sufficiently secured.

  Subsequently, as shown in FIG. 17, the roofing material 74 is sequentially arranged from the eaves side to the ridge side, and the roofing material is constructed so that the portion of the main body metal 2 also covers the leg portion 21 at the ridgeside. At this time, if the gap between the interference portions of the main body 2 and the roof material 74 is conspicuous, a countermeasure such as cutting the back surface of the roof material is performed. When the roofing is finished, as shown in FIG. 18, the metal frame 4 is constructed at the site where the main body fitting 2 is constructed. The cutout 45 of the metal frame is arranged so as to match the rising surface 23 of the main body metal 2, and is fixed to the roof material 74 and the base plate 73 with a fixing material from the base nail hole 43. Although the metal frame 4 is similarly constructed on the opposite side across the ridge core, it is desirable that the metal frame be constructed in a line-symmetrical position with the ridge core as an axis because of the construction of the waterproof sheet 51. When the metal frame 4 can be constructed, as shown in FIG. 19, the headboard 71 is constructed in the ridge except the place where the metal frame is constructed. In addition, a caulking material (not shown) or the like is applied to the portion where the roof material 74 and the metal frame 4 and the roof material 74 and the headboard 71 are engaged to prevent water from entering the building. .

  Further, as shown in FIGS. 20 and 21, a waterproof sheet 51 is applied so as to cover the metal frame 4. It fixes using the tools, such as a tucker, to the edge part of the one side of the ridge core direction which faces the metal frame 4 among the coping 71 fixed to the ridge part 7 at the said process. Further, the wrapping material 72 is fixed so as to cover the headboard 71, and the wrapping material 72 is similarly fixed to the headboard 71 on the opposite side with the waterproof sheet 51 turned over. In this state, since the waterproof sheet 51 is fixed only on one side and further covered with the wrapping material 72, the fixed portion is a kind of fulcrum and can be turned and returned to the ridgeline direction. . When the construction work other than the roof safety member 1 is completed in the state in which the waterproof sheet is turned over, the connecting portion 3 is wound in a round shape and stored in the storage space S (in the metal frame 4). Cover the ends of the stretched metal frame 4 and the other side wrapping material 72. If necessary, the waterproof sheet 51 is pressed by hand to adjust to the shape of the metal frame 4 or the wrapping material 72. By constructing this waterproof sheet 51, it functions as a secondary waterproof to prevent water from entering the ridge 7.

  Then, as shown in FIG. 22, the cover body 6 is covered from above so as to cover a part of the wrapping material 72 near the metal frame 4 and the waterproof sheet 51, and the screw hole 44 of the metal frame and the side surface portion of the cover body. The positions of the provided through holes 65 are aligned, and the metal frame 4 and the cover body 6 are fixed with a dedicated screw. By this process, the construction of the roof safety member 1 is completed (FIG. 23), and the cover body 6 functions as a primary waterproof, that is, prevents water from entering the ridge 7. At this time, the overlapping portion between the wing wrapping material 72 or the waterproof sheet 51 and the cover body 6 is not completely waterproof when a gap is generated. Therefore, for example, an EPDM sealer or the like is formed on the wing wrapping material 72 or the waterproof sheet 51. It is possible to prevent further water from entering by sandwiching the water-stop member 52.

[Second Example]
In the above example, the roof land building (large building) has been described, but the roof safety member 1 of the present invention can be applied not only to the land building but also to the corner building. Since the basic construction is as described in the above embodiment, the difference in construction from the land building in the corner building will be mainly described below.

The same is for the construction of the lower roofing material, working position of the metal body 2, whether pre-roofing material is applied by what intervals leave check, the roofing material of the upper lower when applying a metal frame In the same manner as in the procedure of FIG. The roofing material 74, the metal frame 4 and applying a coping 71 in the order similar to the first embodiment.

  Subsequently, the waterproof sheet 51 is constructed. This embodiment is different from the first embodiment in the construction process of the waterproof sheet 51 compared to the first embodiment. As shown in FIG. 24, the waterproof sheet 51 is always fixed on the large building side (water upper side) to the headboard 71 facing the metal frame 4, and then the upper and lower building wrapping materials 72 are placed with the waterproof sheet 51 half-turned. Install. The connecting portion 3 is stored in the storage space S (in the metal frame), and the waterproof sheet 51 is covered from above the metal frame 4. The corner ridge is also called a descending ridge and is inclined from the ridge side to the eave side in the horizontal direction. Therefore, when rainwater flowing down the wrapping material 72 on the upper side of the water reaches the roof safety member 1 during wind and rain. The water wrapping material 72 covers the waterproof sheet 51 from above the water wrapping material 72, so that water hardly enters between the waterproof sheet 51 and the wrapping material 72. However, if the waterproof sheet is fixed on the opposite side, the waterproof sheet is covered from above the waterside wrapping material, and rainwater that has flowed down from the waterside wrapping material enters the backside of the waterproof sheet and leaks water. Cause. The construction is different from the first embodiment in that the waterproof sheet 51 is fixed on the water side, unlike the construction in the large building where the waterproof sheet is fixed in any direction.

  After the construction of the waterproof sheet 51, the cover body 6 is put on the metal frame 4 to complete the construction (FIG. 26). Also in the case of the corner ridge, since the end portions of the ridge wrapping material 72 on both sides facing the metal frame 4 are covered from the top, the intrusion of water particularly in the overlapping portion between the cover body 6 and the ridge wrapping material on the water side A sufficient water-stopping member 52 such as an EPDM sealer is provided (for example, FIG. 25). In the configuration of the first and second embodiments, since the cover body 6 has substantially the same shape as the building wrapping material 71, the portion where the roof safety member 1 is constructed is as if the building wrapping material 72 is continuous. It is possible to make the presence of the cover body, and thus the presence of the safety member 1 for the roof, inconspicuous.

[Third embodiment]
In a present Example, when a connection part is accommodated in the ridge part of a roof, the thing which can confirm the storage place of a connection part is mentioned as an example. Although the basic structure is the same as that of the first and second embodiments, an example in which a cover body provided with the projection 66 as described above is constructed will be described below. In this embodiment, the construction of the waterproof sheet 51 is omitted.

  As in the first embodiment, after the construction from the underlaying material to the roofing material, the metal frame 4 (optional) and the headboard 71 are constructed. Subsequently, the wrapping material 72 is constructed and the cover body 6 is constructed. Before the cover body is constructed, the two connecting portions 3 are collected and the connecting body 3 is inserted into the protruding portion 66 of the cover body 6. And put it on the top of the building. In accordance with the state of storage of the connecting portion inside the cover body, the storage state of the connecting portion 3 is adjusted using a tool or the like, and the protruding portion 66 stores the cover portion. Fixing to the metal frame 4 or the headboard 71 completes. At this time, the metal frame or headboard is preferably fixed with screws so that the connecting portion can be easily taken out when it is used again.

  That is, the metal frame 4 is constructed in place of the headboard 71, and the connecting portion 3 is not accommodated with the space between the metal frame and the cover body 6 as the accommodation space S, but the construction of the metal frame 4 is optional. By providing the protruding portion 66 on itself, the connecting portion 3 can be stored with the space formed by the protruding portion as the storage space S (FIG. 27). At this time, the headboard 71 does not need to be provided with a cut-out portion as in the first and second embodiments, and can be formed as a storage space with the protruding portion of the cover body. Therefore, by adjusting the fixing position of the cover body to the headboard, A configuration that can greatly reduce the number of points is possible.

  Although the structure and construction method of the safety member 1 for roof of the present invention have been specifically described, the present invention is not limited to the above-mentioned preferred examples, and may be appropriately changed without departing from the fundamental technical idea thereof. Can do. For example, in the shape of the metal frame, the position of the notch 45 is provided not on the center side of the frame base 41 but on the end side, and the notch on the end side is aligned with the position of the body fitting 2 to store the connecting portion 3. It is also possible to shift to the one side of the ridgeline direction with respect to the main body metal fitting 2. In addition, a horizontal plane extending horizontally to the respective leg portions is provided on the upper portion of the main body bracket 2, and the connection portion is fixed to the main body bracket from the leg portion by setting a large loop of the connection portion. Instead of this, the horizontal surface can be hooked from above the metal fitting so that the horizontal surface has a function of retaining.

  INDUSTRIAL APPLICABILITY The present invention can be widely used for improving safety when working on a roof and for performing safety work at various high places.
