Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a technique for constructing a roof in, for example, a wooden house, and more particularly to a technique for fixing rafters and trusses that receive the roof while arranging them on head joints and eaves girders that form the upper part of an outer wall structure.
[0002]
[Prior art]
In general, when constructing a roof of a wooden house, it is necessary to attach a plurality of rafters and trusses for receiving a roof base in a predetermined position of a head joint or eaves girder.
Conventionally, in the rafter attachment work, the position where the rafter is to be attached is marked with ink in the head joint, and after the rafter is attached to the head joint, the clasps are attached to each of the rafters one by one. The rafters are prevented from twisting or falling by being fitted and fixed with nails or the like (see Non-Patent Documents 1 and 2).
[0003]
In addition, a tilting bracket is attached between the rafter or truss and the head joint, but it is difficult to tie the rafter and the head joint directly, such as the rising dimension from the eaves of the rafter or truss is large. In such a case, the rafters are prevented from being blown up by pasting a band plywood between the respective stoppers and the head joints to integrally connect the respective stoppers and the head joints.

[Problems to be solved by the invention]
However, in such conventional rafter installation, the work period is extended because the inking operation, the anti-rolling attachment operation, and the belt plywood attachment operation are performed individually, which causes the work period to be extended. It was. In addition, since each of these operations must be performed at a high place and a place with poor scaffolding, there is a problem in the safety of workers.
[0006]
Accordingly, an object of the present invention is to provide a anti-roll band structure that can shorten the construction period by improving workability and can ensure the safety of the operator.
[0007]
[Means for Solving the Problems]
The present invention comprises a predetermined number of rolling stoppers that prevent the roof construction diagonal members from falling over the girders, and a belt-like plate body that is integrally connected in series with the rolling stoppers. Is set to an arrangement interval at which the roof constituting diagonal member is to be arranged, and an interval between the adjacent other anti-rolling members is set to a fitting interval that can be fitted to the roof constituting oblique member, and the belt-like plate The object is provided by providing the anti-slip belt structure which is protruded by a predetermined amount to be connected to the girders in the direction orthogonal to the series direction of the anti-skids with respect to the anti-skid.

DETAILED DESCRIPTION OF THE INVENTION
A preferred embodiment (first embodiment) of a locking band structure according to the present invention will be described below with reference to the drawings.
[0010]
As shown in FIG. 1 or FIG. 2, the first embodiment includes a predetermined number of locking stoppers 11 that prevent falls on the rafters or truss 2 (the roof construction diagonal) on the head joint 3 or eaves girder (girder). It consists of a band plywood 12 (strip-shaped plate body) in which the stoppers 11 are connected in series.
Further, the stopper 11 has a length L set to an arrangement interval at which the rafter or truss 2 is to be arranged, and a distance d between the other stoppers 11 adjacent to the rafter or the truss 2 can be fitted. The interval is set. On the other hand, the band plywood 12 protrudes from the stopper 11 by a predetermined amount to be connected to the head joint 3 in a direction orthogonal to the series direction of the stopper 11. Hereinafter, the details of the anti-roll band structure 1 will be described.
[0011]
The anti-roll band structure 1 of the present embodiment is attached to a roof base having the same shape and size on a rectangular shape with a simple horizontal cross section of the outer wall structure such as a gable roof or a single-flow roof, for example. In this case, the length L and the interval d of the stopper 11 are prepared in a relatively small number.
[0012]
As shown in FIG. 1, the anti-roller 11 is a square member having a rectangular cross section of width W (for example, 38 mm) × height H (for example, 140 mm). In the case of this embodiment, the length L of the anti-roll is one type of L1 (for example, 415 mm) corresponding to the interval and the number of rafters or trusses 2 to be arranged.
[0013]
The band plywood 12 is a plate material having a rectangular cross section of thickness Wp (for example, 9 mm) × height Hp (for example, 100 mm). The height Hp of the band plywood is set within a range sufficient to connect the stopper 11 and the head joint 3 in the vertical direction. The length Lp of the band plywood is a value obtained by dividing the length in the longitudinal direction of the head joint 3 into a predetermined number (for example, 1820 mm) in consideration of the number of the stoppers 11 (for example, four) and the distance d of the stoppers. Is set to
[0014]
The anti-roller 11 is fixed by nailing with the upper and lower surfaces thereof aligned and arranged on the band plywood 12 with an interval d (for example, 40 mm). For the portion in the height direction of the band plywood 12, a surplus protrusion margin (for example, 35 mm) used for the connection with the stopper 11 is used for the connection with the head joint 3.
[0015]
The left end surface 12a of the band plywood 12 protrudes by an amount of protrusion δ1 (65 mm) obtained by adding an adjustment amount X (for example, 25 mm) to the interval d of the anti-locking 11 with respect to the left end surface of the anti-locking 11 disposed at the left end. Are arranged.
On the other hand, the right end surface 12b of the band plywood 12 is disposed so as to be retracted by an amount of retraction δ2 (25 mm) equal to the adjustment amount X with respect to the right end surface of the stopper 11 disposed at the right end.
[0016]
Thereby, when the end surfaces of the adjacent band plywood 12 are joined and arranged in a plurality, the anti-slip band structure 1 is the same as the interval d of the anti-slip 11 between the anti-locks 11 between the ends. An interval is formed.
[0017]
Hereinafter, the usage mode of the anti-roll band structure 1 of the present embodiment will be described.
As shown in FIG. 1 or FIG. 2, when the roof is constructed, an outer wall structure having the head joint 3 as the uppermost horizontal member is assembled beforehand, and the rafter or the truss 2 is attached to all the head joints 3 to which the rafter or truss 2 is to be attached. The stopband structure 1 is stretched over.
[0018]
In this case, with respect to a method for attaching the anti-slip belt structure 1 to the head joint 3, the lower surface of each anti-slip 11 is placed on the top surface of the head joint 3, and the back surface of the protruding margin portion of the belt plywood 12 is connected to the head 3. , The anti-roll band structure 1 is fixed to the head joint 3 by nailing to the protruding margin portion of the band plywood 12. Moreover, about the adjacent anti-roll belt | band | zone structure 1, the end surfaces of the both sides of each band plywood 12 are put together.
[0019]
As a result, on the head joint 3, the anti-roll 11 having a length L between which the rafters or trusses 2 are to be disposed is fixed integrally with a distance d corresponding to the thickness of the rafters or trusses 2. The
Here, with regard to the positional relationship between the head joint 3 and the rafter or truss 2, for example, the end face of the belt joint board 12 and the end face of the head joint 3 are attached while changing the adjustment amount X of the belt ply board 12 in the locking band structure 1. By matching, the interval at which the rafters or truss 2 should be arranged on the head joint 3 is appropriately formed.
[0020]
And it mounts by dropping while adhering the rafter or the truss 2 between the adjacent locking stoppers 11 respectively. Thereafter, a roof base is constructed on the rafter or truss 2 to construct a roof structure.
[0021]
As described above, according to the present embodiment, the anti-roll band structure 1 is fixed at a predetermined position of the head joint 3, and the rafter or the truss 2 is simply attached between the anti-rotation 11 so far. Since all of the marking out work, the anti-slip mounting work, and the belt plywood mounting work are not required, workability can be improved and the construction period can be shortened.
In particular, in this case, since the work to be performed at the construction site is reduced by manufacturing the anti-roll band structure 1 at the factory, the construction period can be further shortened.
[0022]
Further, according to the present embodiment, as the work required for attaching the rafters or truss 2 is only the attachment of the anti-roll band structure 1 is performed on the head joint 3, it is possible at a high place and a place where the scaffolding is poor. As a result of performing less work than before, it is easy to ensure the safety of the worker.
[0023]
Furthermore, according to the present embodiment, the anti-roll band structure 1 prevents the twisting or rolling of the rafters or trusses 2 by connecting adjacent rafters or trusses 2 in the horizontal direction, which the anti-roller 11 has. In addition, the band plywood 12 has the action of preventing the rafter or truss 2 from being blown up by connecting each of the stoppers 11 and the head joint 3, so that the rafter or truss 2 is integrated more firmly. It becomes easy to make it.
[0024]
In particular, in this case, since the protruding amount δ1 and the retracted amount δ2 of the band plywood 12 of the locking band structure 1 adjacent to each other are set so as to sandwich the rafter or truss 2, the locking band structure 1 is Even if it divides | segments with respect to the head connection 3, the space | interval which should arrange | position the rafter or the truss 2 can be formed continuously, without losing the integrity of the band plywood 12.
[0025]
Further, according to the present embodiment, a rafter or a truss is formed on the head joint 3 simply by bringing the end face of the band plywood 12 and the end face of the head joint 3 together while changing the adjustment amount X of the anti-roll band structure 1 appropriately. 2 can be secured.
[0026]
Hereinafter, another preferred embodiment (second embodiment) of the anti-roll band structure according to the present invention will be described with reference to the drawings.
The anti-roller band structure 10 of the second embodiment includes a portion in which the outer wall is displaced by combining rectangles having different horizontal cross sections of the outer wall structure, such as an L-shaped gable roof and an L-shaped dormitory roof, for example. This is applied when a roof base having a different shape and size is attached, and a plurality of lengths L and intervals d of the anti-rolling 11 are prepared.
[0027]
As shown in FIG. 3, in constructing a U-shaped dormitory roof, after dividing the horizontal section of the outer wall structure into a roof construction area A (for example, A1 to A4) for applying a roof base for each single rectangle, The anti-roll band structure 10 of this embodiment is applied. Hereinafter, regarding the anti-roll band structure 10 of the present embodiment, the same reference numerals are given to the portions corresponding to the first embodiment, and different points will be mainly described.
[0028]
As shown to Fig.4 (a), the attachment information which should attach the anti-roll belt structure 10 to the outer surface of the band plywood 12 of the anti-roll belt structure 10 of this embodiment in the roof construction area | region A, respectively. It is attached. This attachment information includes factory attachment information when attaching to the head joint 3 etc. in advance at the factory, and on-site attachment information when attaching to the head joint 3 etc. at the construction site.
[0029]
Factory mounting information includes a unit number, mounting position number, total length, and end shape value. The unit number indicates the number of the unit obtained by further dividing the roof construction area A into a plurality of units (not shown). The mounting position number is independent of the roof construction area A, and after dividing the outer wall structure into a plurality of mounting surfaces, the base number sequentially assigned to each mounting surface in the eastward direction from the mounting surface on the north side, and the mounting surface number It consists of a branch number with an order. The total length is the entire length of the first anti-roll band structure 10A.
As shown in FIG. 4 (b), the end shape values are as follows: each end of the band plywood 12 is a: end face alignment, b: exit corner (via the corner tree 21), c: entry corner (tani 22). D): a value indicating which of the gable exit corners (contacts the gable wall 5), and there are a right end shape value and a left end shape value when viewed from the outside. Based on the end shape value, the length of the band plywood 12 that protrudes from the stopper 11 is determined.
On the other hand, the on-site mounting information is the same as the factory mounting information except that the floor number indicating the floor to be attached is included instead of the unit number (see FIG. 4A).
[0030]
In consideration of different factors such as the load applied to the roof, the anti-roller 11 is adjacent to the roof construction area A in addition to two types of L1 (415 mm) and L2 (for example, 375 mm). A plurality of items having L3 (remaining various numerical values) for adjustment at the corner portion are prepared.
[0031]
The length Lp of the band plywood 12 is a head connection included in a unit unit in which the roof construction area A is further divided in consideration of the number (for example, 3 to 5) of the stoppers 11 and the distance d of the stoppers 11. 3 is set to a value obtained by dividing the section length La into a predetermined number (for example, 900 mm to 2300 mm). Here, the interval d of the stopper 11 includes an interval d1 (40 mm) for sandwiching only one rafter or truss 2 and an interval d2 (80 mm) for sandwiching both the rafter or truss 2 and the ceiling joist 4. There are a distance d3 (120 mm) between which the rafters or truss 2 are sandwiched between the ceiling joists 4 and a distance d4 (90 mm) that fits closely with the small end wall 5.
[0032]
For example, in the roof construction area A1, with respect to the head joint 3 having the section length La, the first to third anti-rotation belt structures 10A to 10C composed of the anti-rotation 11 and the band plywood 12 are in the longitudinal direction. The anti-roll band connecting structure 20 configured so as to be connectable to each other is used.
[0033]
The first locking band structure 10A (upper side in FIG. 3) includes five locking blocks 11 having lengths L3 and L2 arranged at an interval d2, and the left end surface of the band plywood 12 is positioned at the left end. The right end surface of the band plywood 12 is flush with the right end surface of the anti-slip 11 disposed at the right end while the distance d4 of the small end wall 5 protrudes from the left end surface of the anti-slip 11 disposed at the portion. It is arranged to be.
Among the above-mentioned mounting information, the mounting position number is 1-7 (seventh on the north mounting surface), the end shape value is the left end shape value d (gable corner), and the right end shape The value is a (end face alignment) (see also FIGS. 4A and 4B).
[0034]
The second locking band structure 10B adjacent to the first locking band structure 10A is provided with four locking blocks 11 having a length L2 at intervals d1 and d3. The right end surface protrudes from the right end surface of the stopper 11 disposed at the right end portion by the distance d1 of the rafter or truss 2, while the left end surface of the band plywood 12 is the left end of the stopper 11 disposed at the left end portion. It arrange | positions so that only the space | interval d1 of the rafter or truss 2 may protrude with respect to a surface.
[0035]
Thereby, when the end surfaces of the respective band plywood 12 of the first and second anti-locking band structures 10A and 10B are brought together, the anti-locking 11 at the left end of the first anti-locking band structure 10A, A gap d1 between the rafters or the truss 2 is formed between the anti-roller 11 at the right end of the anti-roller band structure 10B.
Here, the adjustment amount X of the first embodiment is zero.
[0036]
The third locking band structure 10C adjacent to the second locking band structure 10B has the same configuration as that of the first and second locking band structures 10A and 10B. The anti-roll band connecting structure 20 used in the roof construction areas A2 to A4 also has the same configuration as the anti-lock band connecting structure 20, and the description thereof is omitted.
[0037]
As described above, according to the present embodiment, even when the roof construction is different for each roof construction area A, such as forming a hut assembly using the wife wall 5 or interposing the ceiling joists 4. Since the structure of the anti-slip belt structure 10 is divided for each roof construction area A, the structure of the anti-skid belt structure 10 itself can be simplified, and the anti-skid belt structure 10 can be shared. Can also be planned. Such a point is particularly advantageous when adopting a frame wall construction method using square members having the same cross section (2 inches × 4 inches).
[0038]
In addition, according to the present embodiment, since the on-site mounting information or the factory mounting information is attached to the anti-slip belt structure, respectively, when the on-site mounting information is attached, the anti-slip belt structure at the construction site. After marking out only the 10 joints (joint joints of the plywood strips), the workability and safety can be improved by attaching the anti-roller belt structure 10 in a procedural manner, with factory installation information. In such a case, workability and safety can be improved by assembling various units, to which the anti-roller belt structure 10 is attached in advance in the factory, at a construction site. On the other hand, it becomes easy to manage parts of various anti-roll band structures on the basis of on-site mounting information or factory mounting information.
Since other configurations and operational effects are the same as those of the first embodiment, description thereof is omitted.
[0039]
The present invention is not limited to the first and second embodiments, and various changes can be made.
For example, it is possible to attach a plurality of anti-roll band structures 1, 10 to the rafters or trusses 2 or the head joints 3 or eaves girders orthogonal to the end wall 5.
[0040]
Further, in the anti-slip band structures 1 and 10, two band plywood 12 are connected so as to sandwich the anti-slip 11, and such a anti-slip band structure is sandwiched between the head ply 3 and the band plywood 12. It is also possible to fix in a state.
[0041]
Furthermore, in the first embodiment, even when the horizontal cross section of the outer wall structure is a single rectangular shape, for example, when the spacing and thickness of the rafters or trusses 2 are different, or the length of the head joint 3 is equally divided In the case where a surplus length is generated without using it, the anti-roll band structure 10 shown in the second embodiment can be used.
[0042]
Furthermore, in the first embodiment, a plurality of anti-roll band structures 10 divided with respect to the length of the head joint 3 are used, and in the second embodiment, the head joint included in the roof construction area A is used. Although a plurality of anti-slip belt structures 10 divided with respect to the section length La are used, the belt plywood 12 is made of steel, for example, to make it rigid, and the anti-roller 11 is made hollow so as not to impair its strength. As a result, it is also possible to arrange a larger number of the stoppers 11 and make the stopper band structures 1 and 10 themselves longer.
[0043]
In addition, in the second embodiment, the attachment information is attached to the anti-slip belt structure 10. However, the attachment information is attached to the anti-roll belt structure 10 having a relatively simple configuration shown in the first embodiment. Is also effective.
