Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a joint structure between a trunk difference in a building, a so-called upper floor panel, and upper and lower floor wall panels, and more specifically relates to a joint structure between an upper floor panel and upper and lower floor wall panels made of different materials. The present invention relates to a joint structure suitable for joining a floor panel and upper and lower floor wall panels.

<Prior art and its problems> When constructing a building, structural members made of the same material are usually used for basic structural parts.

For example, when building a building with wood panels, the wood panels are used as the structural material, and in PC board structures, concrete PC boards are used as the main structural material. The reason for building with structural members of the same material instead of using structural members of different materials is that if the materials are different, it is difficult to join the structural members together, and furthermore, it is not possible to ensure sufficient rigidity at the joint. It is. For this reason, problems such as not being able to use constituent members appropriate for each part of the building and not being able to obtain the expected livability were presented.

<Means for Solving the Problems> The present invention has been made in view of the above points, and in particular uses wooden panels as the upper floor panels, and uses lightweight aerated concrete as the upper and lower floor wall panels. In the body difference part using panels, the joining hardware attached to the upper floor panel and the embedded metal fittings fixed to the upper and lower floor wall panels are brought into contact with each other, and the above-mentioned embedded metal fittings are connected via the body difference bolts. The above-mentioned joining hardware is joined in a clamped state.

<Function> In other words, the embedded metal fittings fixed to the upper and lower wall panels are brought into contact with each other above and below the joining metal fittings attached to the upper floor panel, and are joined in a clamped state by the body difference bolts. The upper floor wall panel and the lower floor wall panel are joined with sufficient rigidity with the upper floor panel in between.

<Example> The joining structure of the present invention will be explained in detail below with reference to the drawings.

FIG. 1 is a partially cutaway perspective view illustrating a lightweight cellular concrete wall panel common to the upper and lower floors.
In addition, the lower floor wall panel 1 is constructed by assembling steel reinforcements 11 such as channel steel and angle iron in the vertical and horizontal directions, and is embedded above and below the steel reinforcements 11, 11, etc. arranged in the vertical direction. The metal fittings 2, 2 are the openings (see Figure 3)
It is fixed in the position facing indoors. Lightweight aerated concrete 12 is poured into the framework, and the two are integrated to form a panel. Steps 13 and 14 are formed at the upper and lower parts of the upper and lower floor wall panels 1, and the embedded metal fittings 2 are mounted on these steps 13 and 14.
The outer flange is exposed.

As shown in the example in the figure, if the mesh reinforcement 15 is stretched over the steel reinforcement 11, 11..., the adhesion force of the lightweight aerated concrete to the steel reinforcement 11, 11... will be increased, and the strength of the upper and lower floor wall panels will also be increased. do.

FIG. 2 is a partially cutaway perspective view of the upper floor panel 3.

This floor panel 3 is constructed by assembling wooden frame members 31 and 32 forming the side surfaces of the panel into a rectangular shape, and a wooden plywood 33 is stretched over the upper surface thereof.

FIG. 3 shows the steps 13 of the upper and lower floor wall panels 1,
14 is a perspective view of the embedded metal fitting 2 embedded in a state where the outer flange is exposed. The embedded fitting 2 has a substantially U-shaped side surface formed by the web 21 and inner and outer flanges 22 and 23, and reinforcing plates 24 and 24 are provided between the inner and outer flanges 23 to form an opening 25 as a whole. It has a box-like shape. The inner flange 22 is located inside the panel and is connected to the steel reinforcement 11.
The outer flange 23 is located outside the panel and exposed to the step portions 13 and 14. The reinforcing plates 24 and 24 are respectively attached to the web 2.

Further, bolt holes 2 bored in the inner flange 22
It is bolted to the steel reinforcement 11 of the wall panel 1 via 6 and 26. Further, the outer flange 23 is provided with bolt holes 27 and guide pin receiving holes 28, respectively.

As described above, since the outer flange 23 is exposed to each step 13, 14 of the wall panel 1, the bolt holes 27 and guide receivers 28 are also exposed to the steps 13, 14.

FIG. 4 is a perspective view of the joining hardware 4 attached over the entire length of the frame material of the upper floor panel 3, and FIG. 5 is a side view of the same. The joining hardware 4 has a long side surface portion 41 and upper and lower gripping portions 42 and 43, and has a generally U-shaped side surface. Usually the upper grip part 42 has an abbreviated shape on the side.
and a lower grip part 43 of the same shape are attached by bolts V and integrated. Moreover, the upper grip part 4 can adjust the vertical distance between the upper grip part 42 and the lower grip part 43 according to the thickness of the floor panel 3.
2 or the lower grip part 43 is formed into a vertically elongated hole, and the width can be adjusted in a sliding manner.

On the other hand, a box-shaped bulge portion 44 is formed on the outer surface of the side surface portion 41 .

An abutting piece 45 is attached to the box-shaped bulge 44 and the upper grip 42, and similarly the box-shaped bulge 4
4 and the lower grip part 43, another contact piece 46 is attached. That is, an abutment piece 45 and another abutment piece 46 are provided above and below the box-shaped bulge 44 in the center. Further, the abutment piece 45 abuts the outer flange 23 of the embedded metal fitting 2 of the upper floor wall panel, and the other abutment piece 46 abuts the outer flange 23 of the embedded metal fitting 2 of the lower floor wall panel. For this purpose, a bolt hole 47 is formed in the contact piece 45, and a guide pin 48 is provided protruding near the bolt hole 47.

Similarly, a bolt hole 47' is formed in the other abutting piece 46, and a guide pin 48' is provided protrudingly near the bolt hole 47'. The bolt holes 47, 47' are aligned with the bolt holes 27 of the embedded fitting 2, and the guide pins 48, 48'
are fit into each guide pin receiving hole 28. Therefore, the box-shaped bulging portion 44 is provided at the same pitch as the respective embedded fittings 2, 2 of the wall panel 1.

FIG. 6 is a partially omitted perspective view showing a state in which the joining hardware 4 of the above structure is fixed to the upper floor panel 1.
In other words, the inner surface of the side surface portion 41 is placed in contact with the surface 34 of the frame member 31 . Then, the upper and lower end surfaces 35 and 36 of the frame member 31 are sandwiched between the upper gripping part 42 and the lower gripping part 43. In this case, as described above, loosen the bolt V and move the upper grip part 42 and lower grip part 43 up and down to adjust the width.
