Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a joint structure between a lower floor wall panel, an upper floor panel, and an upper floor wall panel, and more specifically relates to a joint structure between a lower floor wall panel and an upper floor wall panel. Arrange the joint hardware, place a floor panel between the upper and lower plates of the joint metal, place the upper floor wall panel and the lower floor wall panel in contact with the outer surfaces of the upper and lower plates of the joint hardware, and connect each with bolts. The present invention relates to a joint structure for a building, characterized in that the joints are joined together.

Traditionally, the main structural members constituting a single building did not use different types of materials; for example, in wood panel structures, wood panel materials became the main structural material, and in wall-type PC structures, etc. PC board is the main structural material.

In other words, a single building was never 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 types of structural materials, it is not easy to transmit vertical loads and horizontal loads to the ground in a well-balanced manner.

The present invention has been made in view of the above points, and in particular uses panel materials made of lightweight aerated concrete as the outer peripheral wall of a building, and on the other hand, uses wood-based panel materials as floor panels laid indoors. We propose a joint structure that integrally joins together, and this joint structure transmits vertical and horizontal loads in a well-balanced manner, and provides a building joint structure that is extremely useful in terms of workability and maintenance of the joint work. It is something.

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, an upper floor wall panel 4, and a curtain board 5.

The lower floor wall panel 1 is constructed in the form of a flat plate by pouring a lightweight cellular concrete material 13 onto a skeleton 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, and the C-shaped steel 31 is stretched on the upper and lower flange surfaces in the opposite direction to the groove 32. In this state, an upper plate 33 and a lower plate 34 are respectively provided. Further, in order to connect them using bolts, the plate and flange are integrally bored and an appropriate number of bolt holes 35, 35, . . . are provided.

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

To fix the lower floor wall panel 1, the floor panel 2, and the upper floor wall panel 4 via the joining hardware 3, first, the peripheral edge 23 of the floor panel 2 is connected between the upper plate 33 and the lower plate 34 of the joining hardware 3. Insert.

In such a state, the outer surface 3 of the lower plate 34
4a is placed in contact with the end surface 14 of the lower floor wall panel 1.

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.

The curtain plate 5 is constructed by pouring lightweight cellular concrete 6 onto small-diameter reinforcing bars 51, and has a length approximately equal to that of the metal fitting 3.

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

The mounting bracket 7 is joined with anchor pieces 71, 71 protruding from the web portion of the mounting bracket 7 being bitten into the lightweight cellular concrete 6.

Further, the flange portion of this mounting bracket 7 is formed with locking pieces 72, 72, and these locking pieces 72, 72
The curtain plate 5 is attached to the joining hardware 3 by being fitted into the groove 32 of the joining hardware 3.

FIG. 3 is a cross-sectional view of the floor hardware attachment joint section joined by the constituent members 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.

As for this joining method, bolts v, v are inserted into bolt holes provided to communicate the web part of the joint metal part 3 and the panel frame material 21, and washers are attached to the web part of the joint metal part 3 and the panel frame material 21, respectively. With the plates 8, 8 in contact with each other, they are screwed together with a nut.

Further, a nail N is driven into the panel frame material 21 through a nail hole formed in the upper plate 33.

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

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.

Further, 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 shows the floor panel 2 connected between the lower floor wall panel 1 and the upper floor wall panel 4 using long bolts and long nuts.
FIG.

In the lower floor wall panel 1, attach the angle frame material 1 in advance.
A nut 16 is attached to the inner surface of the fixed plate 14 joined to the
The bag body 15 containing the water is fixed, and lightweight cellular concrete 13 is poured in this state.

Since the nut 16 is sealed by the fixing plate 14 and the bag body 15, even when the lightweight cellular concrete 13 is cast, the lightweight cellular concrete does not enter the threaded portion.

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 connecting hardware 3
The long bolt 47 is screwed into the nut 46 inside the bag body 45 from the groove 32 side.

Then, by screwing these long bolts 17 and 47 together with the long nuts 9, both wall panels 1 and 4 are pulled together by screwing both long bolts 17 and 47 together using a so-called turnbuckle system. can be joined to the state.

By rotating this long nut 9, the lower floor wall panel 1, the upper floor wall panel 4, and the floor panel 2 are joined, and the curtain plate 5 is placed from the outside of the groove 32 of the joining hardware 3 in the same manner as described above. Then, embed caulking material into the joints as 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 nut 1 inside the bag 15 of the lower floor wall panel 1
6, the bolt 18 is screwed into the joint metal fitting 3 from the groove 32 side.

In this case, the lower plate 34 and the angle frame material 11
A block 1 is installed between the lower plate 34 and the angle frame member 11 so that the lightweight aerated concrete 13 will not be crushed even if they are tightened with the bolts 18.
9 is inserted.

Similarly, in the upper floor wall panel 4, a bolt 48 is inserted into a nut 46 in the bag body 45 from the groove 32 side and screwed into the nut 46.

Furthermore, a block 49 is similarly inserted between the angle frame member 41 and the upper plate 33.

In this manner, in this joint portion, 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 is in contact with the opposite direction of the groove of the joint hardware 3, so the lower floor wall panel 1 and the floor panel 2 are joined together.
The upper wall panel 4 and the upper floor wall panel 4 constitute an integral joint structure by the joining metal fittings 3.

Further, in the same manner as described 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 these joint portions.

As described above, 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 upper 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, respectively. Since the end faces are in contact with each other, vertical loads from the upper part can be smoothly transmitted from the upper floor wall panel to the lower floor wall panel, and the structure is joined mainly by butting the structural members 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, by removing the curtain plate and unscrewing the nuts and bolts to release the joint, the wall panel or floor panel can be replaced. 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.
