Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a mounting structure for a building trunk section consisting of a lower floor wall panel, an upper floor panel, and an upper floor wall panel.
More specifically, a support plate is laid on the lower floor wall panel, a bolt is erected on the lower floor wall panel through this support plate, and the lower piece of the joint metal fittings having a Z-shaped cross section is tightened. The upper floor wall panel and the lower floor wall panel are fastened together via the joint hardware with body-difference bolts by nailing the trunk to the side end surface of the floor panel and the upper piece of the joining hardware to the top surface of the floor panel. The present invention relates to a mounting structure for a torso difference part, characterized by:

(Prior Art) Conventionally, the main structural materials constituting buildings have been made of substantially the same material. For example, in buildings constructed using wood-based panels, the wood-based panel body is the main structural material, and in wall-type PC structures and the like, precast concrete plates are the main structural material.

In other words, it is customary for buildings to be constructed using homogeneous main structural materials, and buildings have not been constructed using a mixture of different structural materials such as wood panels and precast concrete plates. The reason why it was not possible to construct a single building by mixing dissimilar constituent materials in this way is that there was no appropriate means of attachment to attach these dissimilar constituent materials to each other, and the rigidity of the attached parts was insufficient. This is because they were unable to secure it.

In particular, it is easy to obtain a mounting structure in which the upper floor wall panel is firmly attached to the floor panel and the lower floor wall panel in the building trunk section, and the vertical load from the upper floor wall panel is dispersed to the foundation ground via the floor panel. Therefore, it was not possible to actively mix and use different constructs.

(Object of the Invention) Therefore, in view of the above points, the present invention constructs a building with excellent structure, strength, durability, etc. by using different constituent materials in the right places.

That is, in a trunk difference where a precast concrete panel is used as the outer peripheral wall of a building structure and a wooden panel is used as a floor panel of the structure, the two dissimilar components are joined to the support plate and the joint metal fittings and the trunk are formed to have a Z-shaped cross section. This provides a mounting structure for fixing onto the lower floor wall panel via differential bolts.

With this mounting structure, the upper and lower wall panels and floor panels are firmly fixed, and the vertical load from the upper floor wall panels can be smoothly transmitted to the foundation ground via the floor panels and lower floor wall panels. can provide the following.

(Example) Hereinafter, the attachment structure of the trunk difference portion of the present invention will be explained in detail with reference to the drawings.

The joining hardware 1 shown in FIGS. 1 and 2 above,
The mounting structure of the trunk difference part using the support plate 2 and the trunk difference bolt 3 is shown in the exploded perspective view of main parts in FIG.
This will be explained with reference to the longitudinal cross-sectional view in the figure.

The main components in Figures 3 and 4 are the lower floor wall panel 4.
This is a trunk section of a building consisting of an upper floor panel 5 and an upper floor wall panel 6. At the upper end of this lower floor wall panel 4, a number of embedded metal fittings 41 necessary for strength bonding are fixed in advance at appropriate intervals. The embedded metal fitting 41 is provided with a screw hole 41a for vertically installing the barrel difference bolt 3, and screw holes 41b, 41c are provided at the same intervals as the bolt holes 15, 15 of the joining metal fitting 1 and the bolt holes 21a, 21b of the support plate 2. is provided.

To explain the installation construction of the above-mentioned main structure, first, the screw holes 41b, 41c and the bolt holes 21a, 21b are aligned on the embedded metal fitting 41, and the support plate 2 is
, and insert the lower end screw part of the bolt 3 through the insertion hole 23 of the support plate 2.
screw into the screw hole 41a. Then, it is tightened via the fixing nut 31. The fixing nut 31 may be formed integrally with the barrel bolt 3, or may be formed separately and screwed together. Furthermore, a notch 53 is provided in the side end surface 51 of the upper floor panel 5 where the barrel difference bolt 3 is provided to allow the barrel difference bolt 3 to escape.

Next, the upper floor panel 5 is placed on the upper end of the lower wall panel 4, the upper end of the barrel bolt 3 is inserted into the insertion hole 14 of the joining hardware 1, and the lower piece 13 is inserted into the support plate 2.
Put it on top. At this time, the bolt hole 15 of the metal joint 1,
15 and bolt holes 21a, 21b of support plate 2
When aligned, bolt holes 15, 15, 21a, 2
1b and the screw holes 41b and 41c of the embedded metal fittings 41
both communicate. That is, when the fixing bolts 7, 7 are inserted into the bolt holes 15, 15 and 21a, 21b and screwed into the screw holes 41b, 41c, the support plate 2 is fixed on the embedded metal fitting 41, and the joining metal fitting 1 is fixed thereon. becomes. In addition, nails are driven into the side end surfaces 51 and top surface 52 of the upper floor panel 5 through the nail holes 17, 17 and 18, 18, . Secure by nailing to the bottom of the frame.

Then, the upper wall panel 6 is joined to the upper piece 12 of the hardware 1.
Place it on top.

A box-shaped metal fitting 62 with one side open is fixed to a predetermined position in the lower part of the upper floor wall panel 6 by bolts 8 through a block member 61 joined to a reinforcing frame inside the panel. An insertion hole 63 is bored in the lower side of this box hardware 62, and the threaded end of the bolt 3 is inserted into the insertion hole 63, and the threaded end of the bolt 3 is inserted into the upper floor wall panel 6. Place the
A washer 64 is fitted into the threaded end portion protruding inside the box-shaped metal fitting 62, and a fixing nut 65 is screwed into it.

Therefore, the upper floor wall panel 6 is integrally fixed to the lower floor wall panel 4 and the upper floor panel 5 via the box-shaped hardware 62 and the bolts 3. As a result, the external force applied to the lower floor wall panel 6 is received by the joining hardware 1 and the bolt 3 and is directly transmitted to the lower floor wall panel 4 and the upper floor panel 5. In particular, the vertical force applied to the upper floor wall panel 6 is directly transmitted to the lower floor wall panel 4 via the joining hardware 1 and diffused into the foundation ground.

If the reinforcing rib 16 in the shape of a square is fixed to the body 11 of the metal joint 1, the deformation buckling resistance of the metal joint 1 itself can be further increased.

FIG. 5 is an exploded perspective view illustrating the main structure of the trunk section in which upper wall panels 6a and 6b are placed on adjacent upper floor panels 5a and 5b.

In this trunk difference part, upper floor panels 5a and 5
In order to integrally connect the upper floor panels 5a to the joining hardware 1-1 and the support plate 2-1, respectively.
This forms a part to which the upper floor wall panel 6a is attached, and a part to which the upper floor panel 5b and the upper floor wall panel 6b are attached.

That is, each part is attached in the same manner as described above, and the difference is that in order to integrally join the adjacent upper floor panels 5a and 5b, the joining hardware 1-1 and the support plate 2- 1, the two mounting parts are connected.

Therefore, even in the trunk difference portion where the upper floor panels 5a, 5b and the upper floor wall panels 6a, 6b are adjacent to each other,
The external force applied to each upper floor wall panel 6a, 6b is applied to the upper floor panel 5a, 5b via the joining hardware 1-1, the bolts 3-1, 3-2, and the support plate 2-1.
It is transmitted to the lower floor wall panels 4 (4a, 4b), and the adjacent upper and lower floor wall panels and upper floor panels can be integrally fixed to each other.

In the above explanation of construction, the joining hardware 1 is attached after the upper floor panel 5 is laid, but the joining hardware 1 may be attached to the required position of the upper floor panel 5 in advance. Furthermore, the fixing nut 31 and the barrel difference bolt 3 formed separately are embedded in the metal fitting 4 in advance.
1, the fixing nuts 31 are screwed together after the support plate 2 is inserted, and then the connecting hardware 1 is inserted into the barrel difference bolts 3 to attach them.

(Effects) As explained above, the mounting structure of the body difference part of the present invention fixes the upper piece and the body part of the joining hardware to the upper floor panel, and the lower piece is tightly connected to the lower floor wall panel.
Furthermore, since the upper and lower floor wall panels are integrally connected by bolts, the external force applied to the upper floor wall panel made of precast concrete is transferred to the upper floor panel made of wood panels and the lower floor wall panel made of precast concrete. can be communicated smoothly.

Furthermore, the vertical force from the upper floor wall panel can be directly transmitted to the lower floor wall panel, resulting in an extremely good mounting structure for the trunk section. Furthermore, since the shape of the joining hardware itself is extremely simple, the construction is simple and the overall cost of construction is extremely low.
