In this way, the wall body 2 and the shed member 1 are tightly connected.

In order to combine the roof structural member 1 with the wall 2 in this way to construct a house structural member, the panels 20, 21 and the roof structural member 1 are once made into desired shapes at the factory. After being assembled and connected with the bolts 14 and the nut members 15, the connection is released to the maximum size that can be carried, and the reduced product is carried to the site. On the spot,
The panels 20 and 21 and the roof structural member 1 are reassembled into a desired shape, and the panels 20 and 21 are tightly connected to each other by the above-described connecting method. As shown in FIG. 11, the outer wall material 22 is previously attached to the plywood 19 on the side forming the outer wall, so that the sealing material 29 is injected into the panel joint portion and sealing is performed to complete the outer surface finish. As shown in FIG. 11, a fireproof plasterboard 30 is attached to the plywood 18 which is a part of the inner wall. In the plaster board 30, a circular opening 31 having a diameter larger than that of the opening 23 of the plywood 18 and concentric with the opening 23 is formed in a portion overlapping the opening 23 formed in the plywood 18. The openings 23 and 31 formed in the plywood 18 and plasterboard 30 are closed by fitting a closing member 32. As shown in a cross section in FIG. 11, the closing member 32 is formed in the center of a disc having substantially the same diameter as the opening 31 of the plaster board 30 and the same thickness as the plaster board 30, and the opening of the plywood 18 concentric with the disc. It has a shape in which a disk having a diameter substantially the same as that of 23 is placed. If the closing member 32 is formed in the above-described shape, the closing member 32 is opened.
It is possible to easily close the openings 23 and 31 and form a flat surface without dropping or misalignment when fitting into the parts 3 and 31. An inner wall is formed by attaching a cloth 33, which is an interior material, to the surface thus formed.

In the case of such a construction, the beam 5 has the plywood 4 attached to both sides of the frame member 3, so that the beam 5 has a high resistance against the load for deforming the frame member 3 into a parallelogram. And the plywoods 4 on both sides are not deformed unless they are shear fractured at the same time. Further, when the plywood 4 is present on both surfaces, high strength against torsion is exerted. In addition, since the inside is hollow, it is light and convenient to handle.

Further, the bundle 6 is formed by inserting the base end side 6a into the beam 5 and holding it by the vertical frame member 9 so that the tip end side 6b extends above the beam 5. So beam 5
It is possible to increase the bonding strength between the bundle 6 and the bundle 6. As a result, the rigidity of the rooftop structural member 1 is increased.

Further, such a beam 5 can be formed by joining plywood 4 on both sides of the frame member 3 at the factory, and the bundle 6 is also inserted into the beam 5 with the base end side 6a. Since the beam 5 and the bundle 6 can be formed at the same time as the beam 5 in a factory in this state, the accuracy of the beam 5 and the bundle 6 can be significantly improved as compared with the one in the field. Therefore, coupled with the difficulty of deformation,
It is possible to construct high-precision beams 5 and bundles 6 without distortion.

The structure of each part is not limited to the illustrated embodiment, and for example, vertical frame members other than the vertical frame member 9 holding the base end side 6a of the bundle 6 may be omitted, and It may be diagonally arranged diagonally.

Besides, various modifications can be made without departing from the present invention.

[0032]

Since the present invention is as described above, since the beam has a flash structure in which plate members are abutted on both sides of the frame member and has a space inside, the frame member is deformed into a parallelogram. It has a high resistance against the load to be applied, and it does not deform unless the plate materials on both sides are simultaneously sheared and broken.

Furthermore, by inserting the base end side of the bundle into the beam and holding it between the plate materials, and extending the tip end side above the beam to form a bundle, the bundle is one of the flash structures of the beam. Since it is a component, the beam and the bundle have high bond strength. As a result, the rigidity of the entire shed member becomes high.

Further, such a beam can be formed by affixing plate members on both sides of the frame member at the factory, and also a bundle can be formed.
Since the base end side can be inserted into the beam and the beam can be formed at the factory at the same time as the beam, the accuracy of the beam and the bundle can be remarkably improved as compared with the on-site construction. Therefore, coupled with the difficulty of deformation, it is possible to construct a high-precision beam and bundle without distortion.
