Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a joint structure of a trunk difference made of a W1 wall panel, an upper floor panel, and an upper floor wall panel, and more specifically, a joint structure between a lower floor wall panel and a second floor wall panel. A connecting hardware is placed in the area, a floor panel is placed between the upper and lower plates of this connecting metal, and an upper floor wall panel and a lower floor wall panel are placed in contact with the outer surface of the upper and lower plates of this connecting metal, and each is connected to a port. The present invention relates to a joint structure for a building, characterized in that the joint is made through a joint.

Conventionally, the main structural members constituting a single building did not use different types of materials. For example, in a wood panel structure, wood panel materials became the main structural material.
In addition, PC board materials are the main structural material in wall 2 PC structures and the like.

In other words, it has not been the case that one building has been constructed by combining wood panel materials and PC board materials. This is because a rational joining means for joining dissimilar materials has not been available, and there have been problems such as insufficient rigidity of the joined portion.

Moreover, in buildings made of a mixture of these different structural materials, it is not easy to transmit each vertical load and horizontal load to the ground in a well-balanced manner.

The present invention has been made in view of the above points, and in particular uses lightweight cellular concrete acid panel material as the outer peripheral wall of a building.
On the other hand, we proposed a joint structure in which wood-based panel materials are used as floor panels laid indoors and both are joined together, and this joint structure transmits the vertical 1U load and the water mower load in a well-balanced manner. This provides a bonded structure for buildings that is extremely useful in terms of workability and maintenance of the bonding work.

Hereinafter, the joint structure of a building according to the present invention will be explained in detail with reference to the drawings.

FIG. 1 is an exploded view illustrating the joining structure of the present invention.

The main components of this joint structure include a lower floor wall panel 1, a floor panel 2, a connecting hardware 3, a corner wall panel 4, and a curtain board 5.

The floor wall panel 1 is constructed in the form of a flat plate by pouring lightweight aerated concrete material 13 into a frame made by welding mesh reinforcements 12 to one side of an angle frame material 11 constructed in a substantially rectangular shape. .

On the other hand, the floor panel 2 is constructed by extending a surface material 22 made of hardboard or the like onto the upper surface of a wooden panel frame material 21 assembled into a substantially rectangular shape.

Furthermore, as shown in the perspective view of FIG. 2, the connecting hardware 3 is made of a so-called C-shaped steel 31 having a substantially U-shaped cross section as a base. With the upper plate 33. A lower plate 34 is provided respectively. In addition, in order to connect using ports, the plate and flange must be integrally drilled and the appropriate number of bolt holes 35, 35...
is provided.

On the other hand, in the upper floor wall panel 4, a mesh reinforcement 42 is welded to an angle frame member 41 having a substantially rectangular shape similar to the lower floor wall panel 1, and a mesh reinforcement 42 is welded to form a rib. It is made into a substantially flat plate by pouring it.

First, the lower floor wall panel 1, the floor panel 2, and the second floor wall panel 4 are fixed via the connecting hardware 3.
The peripheral edge part 23 is fitted between the -1- plate 33 and the lower plate 34 of the joining hardware 3.

In this state, the outer surface 34a of the lower plate 34 is placed in contact with the end surface 14 of the lower floor wall panel l.

Similarly, the end surface 44 of the upper wall panel 4 is placed on the outer surface 33a of the upper plate 33.

Furthermore, the curtain plate 5 is arranged from the outside of the groove portion 32 of the joining hardware 3.

This curtain plate 5 is constructed by pouring lightweight cellular concrete 6 into small-diameter joints 51, and has a length approximately equal to that of the joining hardware 3.

Furthermore, a mounting bracket 7 is fixed to this inner surface side.

The take-off metal fitting 7 is joined with anchor pieces 71 and 71 protruding from the web portion of the take-off metal fitting 7 being bitten into the lightweight aerated concrete 6.

Also, a latching piece 72 is attached to the flange portion of the mounting bracket 7.
72 is formed, and the hooking pieces 72, 72 are fitted into the grooves 32 of the joint hardware 3, so that the curtain plate 5 is attached to the joint hardware 3.

FIG. 3 is a cross-sectional view of the metal fittings attachment joint section joined by each component shown in the above exploded view.

That is, the peripheral edge portion 23 of the floor panel 2 is placed between the upper plate 32 and the lower plate 34 of the joining hardware 3 and joined.

This joining method involves inserting bolts V,
Insert and connect the joint part 3 of the joint part 3 and the panel frame material 21.
With the washer plates 8.8 in contact with each of them, they are screwed together with nuts.

Further, nails N are driven into the panel frame material 21 through the nail holes drilled in the nib plate 33.

In such a state, the outer surface 34a of the lower plate 34 of the joining hardware 3 is brought into contact with the end surface 14 of the lower wall panel 1, and the end surface 44 of the upper wall panel 4 is placed on the upper surface 33a of the upper plate 33. .

The curtain plate 5 is disposed in the groove portion 32 opened toward the outside of the joint metal fitting 3 via the mounting fitting 7.

Furthermore, caulking material is embedded in each joint between the lower floor wall panel 1 and the curtain plate 5 and between the upper floor wall panel 4 and the curtain plate 5 as necessary.

FIG. 4 is a cross-sectional view of a bolt joint where the floor panel 2 is fixed between the lower floor wall panel 1 and the upper floor wall panel 4 using long bolts and long nuts.

In the lower floor wall panel l, a bag body 15 containing nuts 16 is fixed to the inner surface of a fixing plate 14 which is joined to an angle frame member 11 etc. in advance, and lightweight aerated concrete 13 is poured in this state. be.

Since the Nando 16 is in a sealed state with the fixing plate 14 and the bag body 15, even when the lightweight cellular concrete '13 is poured, the lightweight cellular concrete will not enter the cap part.

The long bolts 17 passing through the fixing plate 14 and the lower plate 34 on the groove 32 side of the metal joint 3 are screwed together with the nuts 16.

Similarly, in the upper floor wall panel 4, the groove 3 of the metal fitting 3
The long port 47 is screwed onto the nut 46 inside the bag body 45 from the second side.

Then, by screwing these long ports 17 and 47 together with the long nuts 9, the two wall panels 1.4 are drawn together by screwing the two long ports 17 and 47 together using a so-called turn-and-turn method. can be joined to the state.

By rotating this long nut 9, the lower floor wall panel l, the upper floor wall panel 4, and the floor panel 2 are joined, and the curtain plate 5 is disposed from the outside of the groove 32 of the joining hardware 3 in the same manner as described above. Fill the joints with caulking material if necessary.

FIG. 5 is a cross-sectional view of a portion bearing horizontal proof stress, a so-called bolt joint for shear proof stress.

First, the port 18 is screwed into the nut 16 in the bag 15 of the lower floor wall panel 1 from the groove 32 side of the coupling hardware 3.

In this case, even if the lower plate 34 and the angle frame member 11 are tightened with the bolts 18, the lightweight aerated concrete 13
A block 18 is interposed between the lower plate 34 and the angle frame member 11 to prevent crushing.

Similarly, in the upper floor wall panel 4, the nut 4 inside the bag body 45 is
The port 48 is inserted into the groove 32 from the groove 32 side and screwed into the port 48.

Moreover, a block 48 is similarly inserted between the angle frame member 41 and the upper plate 33.

In this way, in the water joint, the lower floor wall panel 1 and the joining hardware 3 are joined together, and the upper floor wall panel 4 and the joining hardware 3 are joined separately and independently.

Even if the joints are separate and independent, the peripheral edge 23 of the floor panel 2 comes into contact with the opposite direction of the groove of the joint hardware 3 and is joined.
In this case, an integrated joining structure is formed by the joining metal fittings 3.

Further, similarly to the above, the curtain plate 5 is fitted so as to close the groove portion 32 of the joint metal fitting 3, and caulking material is embedded in the joint portions thereof.

As described below, in the joint structure of the present invention, the peripheral edge of the floor panel is arranged between the upper and lower plates of the joint hardware, and the -h floor stiff wall panel and the lower floor wall panel are attached to the outer surfaces of the upper plate and the lower plate of the joint hardware. Since each end surface is in contact with each other, the vertical load on the upper part is smoothly transmitted from the second floor wall panel to the lower floor wall panel.Moreover, it is a joint structure in which the structural members are mainly butted against each other. Therefore, it is easy to connect dissimilar structural materials without requiring complicated metal fittings.

In addition, the arrangement of the curtain plate simplifies the fit in the trunk section, resulting in a good external design.

Furthermore, ground inspection of wall panels and floor panels is also possible by removing this curtain plate and releasing the threaded connections of nuts and bolts to release this connection. Furthermore, the space within the groove of the bonded metal can be used as a wiring or piping duct, making it an extremely effective building bonding structure from both a practical and technical standpoint.
