In order to make this building panel 1 an outer wall and an inner wall of a building such as a house, a plurality of the panels are arranged so as to have a predetermined structure, and a frame member 1a of the adjacent building panel 1 is provided.
These are tightly connected to each other via a plurality of bolts and nuts. When the building panel 1 forms an outer wall of a building, an exterior material 1c is provided on an outer surface thereof, and a plaster board 1d and wallpaper 1e are provided on an inner surface thereof in advance in a factory. Then, after a building is formed by combining the building panels 1 in the factory, the building is disassembled into a size that can be loaded on a transport truck, transported to a building site, and assembled at the building site to form a building.

A flanged nut 3a, which is an embedding nut constituting the fastening mechanism 3, is embedded at a predetermined position of, for example, the lateral frame 1a of the building panel 1 constituting the outer wall. In the case of constructing an architectural scaffold for construction of a two-story building roof or the like, a concave portion 1f for burying the flanged nut 3a is provided with a building panel 1 constituting an outer wall of the second floor. The recess 1 is provided on the inner surface side of the lower and upper horizontal frame members 1a.
A through hole 1g is formed from f to open on the outer surface of the exterior material 1c of the building panel 1. As described above, when the concave portions 1f are provided at the upper and lower portions, each of the concave portions 1f is provided on the same straight line in the vertical direction. The position of the concave portion 1f is not limited to the horizontal frame member 1a, but may be provided in the vertical frame member depending on the fastening position. Further, the depth of the concave portion 1f is at least
a may be slightly deeper than it can be stored, but when the male screw body 3b is stored in the building panel 1 when not in use, for example, it is deepened to about 1/2 of the depth dimension of the frame material 1a. Then, the male screw 3b is connected to the building panel 1 to the extent that the rear end of the male screw 3b contacts the plaster board 1d.
What is necessary is just to be comprised so that it may be immersed in.

The flanged nut 3a is fixed to the recess 1f using a nail. That is, the flange portion 3a of the flanged nut 3a
In a, two through holes 3ab for vertically inserting a nail as a fastening tool are formed vertically. And the fixed flanged nut 3
A male screw 3b constituting the fastening mechanism 3 inserted into the through hole 1g from the outside is screwed into a. This male screw body 3b
For example, the length is substantially equal to the thickness of the building panel 1, and a male screw is formed over substantially the entire length of the outer peripheral surface. The rear end is screwed into the flanged nut 3a, and the front end is formed through the through hole 1g. Exposed to the outside of the object panel 1,
It supports the scaffold member 2. An annular groove 3d in which no external thread is formed is formed at a position separated from the front end of the external thread body 3b by a predetermined distance, for example, a distance corresponding to a length enough to screw the nut 3c sufficiently. A groove 3e into which a driver or the like for rotating the male screw body 3b is inserted is formed on the distal end surface.

The male screw body 3b is screwed to a flanged nut 3a when shipped from a factory, and a nut for fixing the mounting plate portion 2a of the scaffold member 2 to the outer front end of the building panel 1. 3c may be screwed together. Alternatively, male screw body 3b
May be screwed with the cap nut 4 to cover the front end of the cap. Such a cap nut 4 can be screwed into the male screw body 3b when the male screw body 3b is housed in the building panel 1 after the construction is completed, so that the through hole 1
Since g is closed and serves as a mark, when the scaffold member 2 is fastened again when repairing a building or the like, the fastening position can be easily specified, and the work can be speeded up. . When using the cap nut 4, the through hole 1
Needless to say, packing and the like are performed to prevent water from entering the g.

The scaffold member 2 includes a mounting plate portion 21 which is in close contact with the outer wall of the building panel 1, and a scaffold main body portion 22 which fixes at least the base end 22m to the mounting plate portion 21. The mounting plate portion 21 is a rectangular iron plate. In this embodiment, there are two upper and lower portions, each having a mounting hole 21a through which the male screw body 3b penetrates in the upper half portion, and a tread plate in the lower half portion. The scaffold main body part 22 on which the like is placed is fixed.

The scaffold main body 22 is made of a metal pipe material, and has a lower mounting pipe 22b whose one end is welded to the mounting plate 21 and an upper mounting pipe 22c which is welded to the upper mounting plate 21. Outer vertical pipe 22d to be welded to the ends of pipes 22b and 22c, and both mounting pipes 22b and 22c
Are welded to a surface of the outer vertical pipe 22d opposed to the inner vertical pipe 22e, an inner vertical pipe 22e welded to a substantially central portion of the inner vertical pipe 22e, a lateral pipe 22f connecting the outer and inner vertical pipes 22d, 22e at a substantially central portion thereof. And a support portion 22g formed of an L-shaped support fitting. The outer vertical pipe 22d extends above the upper attachment pipe 22c, and projects above the eaves when fastened. In addition, support part 22g
Is formed with a screw hole 22ga in the horizontal direction, so that the plate material 6 can be sandwiched by screwing the bolts 5 together.

In such a configuration, the building panel 1 is temporarily assembled in a factory to form a building, and then the building panel 1 is transported to a building site as a block having a combination of sizes that can be loaded on a truck. . At the construction site, the building is assembled by assembling the blocks brought in. After this,
A scaffold for construction is constructed at a predetermined position on the second floor for joint treatment of the second floor, installation of gutters, roofing work, painting of eaves lining, and the like. In this case, the scaffolding member 2 is fixed to the building panel 1 by the fastening mechanism 3 while the building panel 1 on the second floor for fastening the scaffolding member 2 or the block including the building panel 1 is on the ground. Then, the building panel 1 or block is fixed to the second floor.

First, the driver is engaged with the groove 3e at the tip of the male screw body 3b so that the annular groove 3d protrudes until it reaches a position substantially the same as the outer surface of the building panel 1. Adjust the length. Next, the mounting hole 21a of the mounting plate 21 of the scaffold member 2 is engaged with the annular groove 3d. In the case of this embodiment, since the mounting plate portion 21 is located up and down, by engaging each mounting hole 21a with the annular groove 3d,
A scaffolding member 2 attaches to the outer surface of the building panel 1. In this state, the nut 3c is fastened, the mounting plate 21 is brought into close contact with the outer surface of the building panel 1, and the scaffold member 2 is fixed. In this case, in order to prevent the exterior material 1c from being damaged, the thin cushion material 7 is placed between the mounting plate 21 and the exterior material 1c.
May be interposed.

A complete architectural scaffold is obtained by bridging the treads 8 and handrails to the plurality of scaffold members 2 fixed as described above. The tread plate 8 includes mounting pipes 22b and 22c between the outer vertical pipe 22d and the inner vertical pipe 22e.
If the width dimension is made to correspond to the distance between the facing surfaces of the outer and inner vertical pipes 22d and 22e, it is fixed because it is sandwiched between the vertical pipes 22d and 22e. At least it will not fall in this direction. On the other hand, since there is nothing prohibiting movement in the longitudinal direction of the tread 8, the tread 8 may move when an external force greater than the frictional force between the tread 8 and the scaffold member 2 acts. Therefore, a member for prohibiting movement is fixed on the back surface of the tread plate 8 so as to sandwich the attachment pipes 22b, 22c and the horizontal pipe 22f, thereby preventing falling. In addition, if the long narrow plate member 6 is fixed to the support portion 22g with the bolt 5, a handrail can be realized. In addition, treads 8
By sandwiching the same long plate as the handrail between the vertical pipes and the two vertical pipes 22d and 22e, it is possible to effectively prevent the object placed on the tread plate 8 from falling.

As described above, since the scaffolding member 2 is directly fixed to the outer surface of the building panel 1, it may become unstable due to the unevenness of the surface of the ground as in the case of standing on the ground. In addition, it can be stably installed even in a narrow place, and a problem such as collapse due to insufficient coupling with a building can be solved. In addition, mounting can be performed only by fastening the nut 3c of the fastening mechanism 3, and removal can be performed by loosening the nut 3c. Therefore, the operation is easy, no skill is required, and the operation time can be reduced. Furthermore, by using two mounting plate portions 21, the scaffold member 2 can be firmly fastened without rotating when fastening. After removal, the external thread 3
If b is stored in the building panel 1 and the cap nut 4 is screwed to the end to close the through hole 1g, the building can be quickly repaired at a later date when the building is repaired. Can build a scaffold.

The present invention is not limited to the embodiment described above. In the above-described embodiment, the fixing mechanism 3 is provided at two positions in the upper and lower directions. However, the present invention is not limited to the two positions, and may be only one position on the upper side. It may be provided in the middle and lower three places. When the fastening mechanism 3 has only one upper position, the adjacent scaffold members 2 may be reinforced by connecting them with braces, diagonal braces, or handrails. Even in the case where the fastening mechanism 3 is provided in one place, the mounting plate 21 of the scaffolding member 2 is provided in two upper and lower places in order to secure stability when abutting against the building panel 1. It may be provided.

In the above embodiment, the male screw body 3b is used for the fastening mechanism 3, but as the fastening mechanism 3, as shown in FIG. It may be composed of a flanged nut 103a and a bolt 103m. Such a flanged nut 103
In the case of a, the screwed portion with the 103 m bolt becomes long, so that it can be firmly fastened. In this example,
After removing the scaffold member 2, the through hole 1 is formed using the cap nut 4.
Since g cannot be closed, the opening is closed with a lid member, a caulking material or the like after the bolt 103m is pulled out from the through hole 1g. Even in this example,
Since the flanged nut 103a remains buried in the building panel 1, it can be easily constructed when a building scaffold is required for repair or the like, as in the above embodiment. In the case of a concrete building panel, the embedding nut may be constituted by an insert nut previously embedded in the panel.

Further, as the supporting metal, a flat metal fitting 122g having through-holes 122gb formed near both ends of a strip-shaped member as shown in FIG. 7 is used instead of the L-shaped supporting metal as in the above embodiment. It may be welded to the outside or inside of the outer vertical pipe 22d. In the case of such a flat metal fitting 122g, if the diagonal braces or the like are connected to the through holes 122gb with bolts or turnbuckles, it becomes easy to connect the adjacent scaffold members 2. Also,
If a pipe material having connecting portions at both ends is attached with a fastener such as a bolt, a handrail can be constructed between the adjacent scaffold members 2. Further, a brace, a diagonal brace, and the like and a pipe material for a handrail bridging in the horizontal direction are connected to the through-hole
If they are connected and fixed together at 2 gb, the safety of construction personnel can be improved and the scaffold member 2 can be reinforced.

In addition to this, the pipe material for the handrail
If it is configured to include a pipe and a connecting member such as a hinge or a universal joint for rotatably connecting the pipes to each other, the pipe can be bent, for example, at a central portion in the length direction. By preparing the pipe material having such a configuration, when the scaffold members 2 are respectively attached to the wall surfaces formed at an angle, for example, the front wall surface and the side wall surface of the building, the scaffold members 2 Can be easily connected, and the construction of the handrail is facilitated. In this case, the lengths of the two pipes may be equal or different.

The building panel 1 may be a panel in which plywood is provided on one side in the two-by-four construction method, in addition to the above-mentioned flash structure. Further, it may be a concrete panel. In addition, the configuration of each unit is not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention.

[0027]

As described above, according to the present invention, the scaffolding member is directly detachably fastened to the building panel by the fastening mechanism, so that it is not affected by the installation place and the assembly work. , Can be built in a strong state at all times. Moreover, even if it is removed when it is no longer needed, the scaffolding member can be easily attached again because a part of the fastening mechanism is embedded in the building panel.
