Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a building bonding structure in which a floor panel and a wall panel are fixed to a foundation via a bonding metal fitting. A plate having a joint structure in which a wall panel is erected on top of a wall panel, in which the web surface on the opposite side of the groove of the joint metal made of C-shaped steel is in contact with the outer frame surface of the floor panel, and the plate projects on the side opposite to the opening of the groove. The back side of the plate is placed on the top surface of the panel face material, the plate is nailed to the panel frame, and a wall panel is erected on the top surface of the plate.

Traditionally, different types of main structural members were not used to make up a building;
For example, in a wood-based panel structure, the wood-based panel body is the main structural member, and in a wall-type PC structure, etc., the PC board is the main structural material.

In other words, the reason that buildings are not constructed by combining wood panels and PC boards is that there was no suitable means of joining these dissimilar materials together, and that the joints were not sufficiently rigid. This is due to reasons such as not being able to secure the required amount.

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, which is not desirable from the viewpoint of the overall structure of the building.

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 structure, while wooden panels are laid indoors and used as floor panels of the structure. We provide a joint structure that fixes both of these on the foundation, and this joint structure allows vertical and horizontal loads to be transmitted in a well-balanced manner, and is an extremely useful building joint structure from the viewpoint of ease of construction of the joint work. It provides:

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

FIG. 1 is an exploded sectional view showing the main components in order to explain the joint structure of the present invention.

The main components of this joint structure are a cloth foundation 1, an architrave 2 placed on the top surface of the foundation, a floor panel 3, and a joint hardware 4 disposed on the outer frame surface of the floor panel 3.
It consists of a wall panel 5 erected on the plate of the joint hardware 4.

The cloth foundation 1 is a foundation structure provided directly under the outer peripheral wall of a building, and although not shown, a footing portion is provided at the bottom thereof for transmitting a vertical load to the ground.

On the other hand, the top surface of the cloth foundation 1 is leveled to ensure the levelness of the building.

A flat architrave 2 is placed on the top surface of the cloth foundation 1 whose top has been leveled.

The floor panel 3 has panel frames 31, 3 in a substantially rectangular shape.
1... and a face material 32 is stretched on the upper surface thereof, and reinforcing bars are provided inside as necessary.

Further, the joint hardware 4 is mainly composed of a C-shaped steel 41, and as shown in the perspective view of FIG. 2, the C-shaped steel 4
A plate 43 is fixed onto the upper flange 4a of the groove 42 so as to protrude in a direction opposite to the opening of the groove 42.

Furthermore, bolt holes 44, 44, . . ., which pass through the upper and lower flanges 4a, 4b, are bored in the plate 43 at substantially the same pitch as the anchor bolts on the cloth foundation 1, which will be described later.

The wall panel 5 is made of an angle frame material 51 assembled into a substantially rectangular shape with mesh reinforcements 52 stretched to form a skeleton.
Lightweight cellular concrete 53 is poured into this frame.

That is, according to the exploded sectional view shown in FIG. 1, the structure is such that a wooden floor panel 3 is connected between a cloth foundation 1 made of concrete and a wall panel 5 made of lightweight cellular concrete.

A joining hardware 4 is arranged as a hardware for joining the cloth foundation 1 to the floor panel 3 and wall panel 5.

FIG. 3 is a sectional view of a portion in which the main components in FIG. 1 are combined as a floor hardware attachment portion.

An architrave 2 is placed on the top surface 1a of the cloth foundation 1,
A floor panel 3 is placed on the cloth foundation 1 via the architrave 2. Then, the groove 42 of the joint 4 is directed toward the outside of the building, and the web surface 4c on the opposite side of the groove 42 is brought into contact with the outer frame surface 33 of the floor panel 3. Moreover, at this time, the back surface 43a of the plate 43 fixed to the upper flange 4a is placed on the upper surface of the face material 32.

In this state, the joint 4 is fixed to the panel frame material 31 with screws a, a through the screw holes (not shown) provided in the web 4d, and the nail holes (not shown) in the plate 43 are fixed. Drive nail b through the hole.

Also, at this time, the lower flange 4b of the metal joint 4 is placed on the architrave 2.

Next, the lower end surface 5a of the wall panel 5 is placed on the plate 43 of the joining hardware 4, and is erected.

On the other hand, since the groove 42 of the metal joint 4 is open toward the outside of the building, if it is necessary to close the groove 42, the cover plate 6 is fitted from the outside.

This cover plate 6 serves as a partition plate between the cloth foundation 1 and the wall panel 5, and is required to be durable, so it is usually constructed by bending a patterned PVC steel plate or the like into a substantially U-shaped cross section. There is. Moreover, the structure is such that the U-shaped opening faces the opening of the joint metal fitting 4 and is fitted into the metal fitting 4.

Further, caulking material 7 is embedded in the boundary surface between the lower end surface of the wall panel 5 and the cover plate 6 to completely drain water.

FIG. 4 is a sectional view showing a portion integrally connected via an anchor bolt or the like in the above connection structure.

According to this sectional view, anchor bolts 11 protruding from the cloth foundation 1 and fixing plates 5 in the wall panel 5 are shown.
A joint bolt 12 is screwed into a nut 15 in a bag body 14 fixed to the bag body 4, and a long nut 13 is used to screw the joint bolt 12 into the nut 15.

With this structure, when the long nut 13 is rotated in a certain direction, the cloth foundation 1 is rotated through the lower flange 4b of the C-shaped steel 41 of the joint 4, and the same flange 4
The wall panels 5 are respectively screwed through the holes a.

Moreover, the long nut 13 is connected to the C-shaped steel 4 of the joint metal 4.
Since it is housed in the groove 42 of the anchor bolt 11, it can be easily rotated from the outdoor direction, and if necessary, the threaded connection between the anchor bolt 11 and the joint bolt 12 can be released by rotating it in the opposite direction. At the very least, it becomes easy to release this bond.

The above-mentioned connection structure using the anchor bolt 11, joint bolt 12, and long nut 13 may be provided at a predetermined location on the cloth foundation 1, and the arrangement interval,
The so-called pitch is predetermined by the position of the building's wall panels.

The nuts 15 in the wall panel 5 are housed in a bag body 14 fixed to a fixed plate 54 which is fixed integrally with the vertical angle frame member 51, so that they remain outside even after the lightweight aerated concrete 53 is cast. It has a structure that allows it to be screwed together with the bolt 12.

FIG. 5 shows a cross section of a portion where the floor panel 3 and wall panel 5 are connected by bolts 56 for shear strength.

This joint structure is different from the structure shown in FIG. 4 in order to bear horizontal loads, and is integrated with the horizontal angle frame member 51 of the wall panel 5 at a predetermined pitch at a position where the anchor bolt 11 is not erected on the cloth foundation 1. A block 55 is provided in particular, and a bolt 56 passes through this block 55 and is screwed into the nut 15 in the bag body 14 from within the groove 42 of the metal fitting 4.

In other respects, the connection between the metal fittings 4 and the floor panel 3 is the same as that shown in FIG. 4.

Moreover, in either case, the groove portion 42 of the joining hardware 4
By fitting a cover plate 6 made of a PVC steel plate or the like so as to cover the area, the separation between the cloth foundation 1 and the wall panel 5 is improved, and the external design is maintained well.

Furthermore, since the openings of the groove portion 42 and the cover plate 6 face each other, a space portion 61 is formed. Therefore, this space 61 can also be used as a wiring or piping duct around the outside of the building.

Bring the web surface opposite the groove of the joining hardware into contact with the outer frame surface of the floor panel, place the back side of the plate fixed to the upper flange on the top surface of the floor panel face material, and nail the plate and the floor panel frame material together. Since it is fixed, the metal fittings on the foundation and the floor panel are integrated, and the vertical load from the wall panel erected on the top of this plate is applied to the plate, the panel frame, and even the metal fittings (C-shaped steel web). This provides sufficient support, making it a suitable structure for joining dissimilar structural materials.
