Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a joint structure of a building in which a floor panel is placed on a foundation and a wall panel is erected, and more specifically, the present invention relates to a joint structure of a building in which a floor panel is placed on a foundation and a wall panel is erected. , relates to a joint structure for a building, characterized in that a joint metal fitting having a Z-shaped cross section is disposed at the end of the body, an upper piece, and a lower piece.

(Prior Art) Conventionally, the main structural materials used to construct buildings are made of substantially the same material. For example, in a building with a wood panel structure, the wood panel body is the main structural material, and in a PC wall structure, etc., a precast concrete panel is the main structural material. In other words, the main structural materials for buildings are usually made of the same material.
Buildings were rarely constructed using a mixture of wood panels and precast concrete panels.

The reason why it was not possible to form a single building by mixing different types of structural materials is that there was no suitable joining means to join these different types of structural materials together, and the joints This is because sufficient rigidity could not be ensured.

In particular, it was not possible to easily obtain a joint structure that transmitted and dispersed the load applied to the wall surface to the floor surface, so it was not possible to transmit the vertical and horizontal loads of the building to the ground in a well-balanced manner, and the mixed use of different types of structural materials were reluctant.

(Objective and Summary of the Invention) Therefore, in view of the above points, the present invention aims to actively utilize different types of constituent materials, and in particular uses precast concrete panels as the outer peripheral wall of the building structure, while wood panels are used as the floor panels of the structure. The present invention provides a joining structure in which two dissimilar constituent materials are fixed on a foundation using a joining hardware formed with a Z-shaped cross section. This joint structure allows the vertical and horizontal loads applied to the exterior wall panels to be transmitted to the entire floor panel in a well-balanced manner, and ultimately to the ground via the foundation.

(Example) The joint structure of a building according to the present invention will be explained in detail below with reference to the drawings.

FIG. 1 is a perspective view of a joining metal fitting 1 used in the joining structure of the present invention.

The joining hardware 1 has an upper piece 12 that extends from the upper side of the body part 11 in a direction perpendicular to the body part 11, and also has a lower piece 13 extending from the upper side of the body part 11 in the direction perpendicular to the side opposite to the upper piece 12. The cross section is formed into a substantially Z-shape. The height of the body portion 11 is approximately equal to the thickness of the floor panel, as will be described later. Further, an anchor insertion hole 14 is bored approximately in the center of the upper piece 12.
A mouth-shaped reinforcing rib 15 is provided on the surface of the body 11. Furthermore, nail holes 16..., 17... are bored in the body portion 11 and the upper piece 12 at required positions, respectively.

FIG. 2 is an exploded perspective view showing the main components of the joint structure.

This main structure includes a cloth foundation 2, an architrave 21 placed on the top surface of the foundation, an anchor bolt 3 planted on the cloth foundation z, and a floor panel 4 placed on the architrave 21. , consists of a wall panel 5 erected on the top surface of the end of this floor panel 4.

The cloth foundation 2 is a foundation structure provided directly under the outer peripheral wall of a building, and although not shown in the drawings, a connecting part for transmitting the load to the ground is provided at its lower part.

The upper surface of the cloth foundation 2 is leveled at the top to ensure the levelness of the building, and a long flat architrave 21 is placed on the leveled upper surface.

Further, anchor bolts 3, 3, . . . are installed at required positions on the upper surface of the cloth foundation 2, passing through the architrave 21. The one-way panel 4 is constructed by assembling a panel frame material 41 in a substantially rectangular shape, and a panel material 42 is attached to the upper surface of the panel frame material 41, and reinforcing bars are provided inside as required. Moreover, anchor bolt 3 is
The contacting side end surfaces 43 are provided with cutouts 44, 44, . . . into which anchor bolts are fitted.

Moreover, the wall panel 5 is made of an angle frame material 51 assembled into a substantially rectangular shape.
Mesh reinforcement 52 is pasted on the bone to form a bone rest, and lightweight aerated concrete 53 is poured into this bone rest. In addition, a box-shaped metal fitting 55 (hereinafter referred to as box metal fitting) is fixed at a required position at the lower end of the wall panel 5 with a block material 54 interposed therebetween by bolts 56. The box hardware 55 has an opening on one side of the indoor side of the wall panel 4, and a spanner or the like is inserted into this opening to screw the fixing nut of the anchor bolt 3 as described later.

Next, the joint structure of the present invention will be explained with reference to the joint cross-sectional view of FIG. 3 along with its construction procedure.

First, the floor panel 4 is placed on the cloth foundation 2. At this time, cutouts 44, 44... are provided in advance in the floor panel 4,
Anchor bolts 3.3 are inserted into these notches 44, 44...
Place it so that it is fitted. Then, insert the tip of the anchor bolt 3 into the anchor insertion hole 14 of the joining hardware l,
The upper piece 12 is placed on the upper surface 42 of the end of the floor panel 4, and the lower piece 13 is placed on the cloth foundation 2, and the body 11 is brought into contact with the side edge 43 of the floor panel 4, and each It sticks.

Note that the construction is not limited to the above procedure; for example, the upper piece 12 and body part 11 of the joining hardware 1 are placed and abutted on the upper surface 42 and side edge 43 of the floor panel 4 in advance, and then lowered with nails attached. The piece 12 may be placed on the cloth foundation 2.

In such a state, the nail holes 1B in the body portion 11 and the upper piece 12.

16...and 1? , 1? . . . Drive the required nails to fix the joining hardware 1 and floor panel 4 together. Next, hang the wall panel 5 and insert the tip of the anchor port 3 into the bolt hole provided in the lower piece of the box hardware 53. is inserted and placed on the upper piece 12 of the joining hardware 1. Then, screw the fixing nut 32 through the washer 31 from the opening on the interior surface of the floor panel 4.
A wall panel 5 is fixed on top. As a result, the floor panel 4 is fixed on the foundation 2 while being pressed by the upper piece 12 of the joining hardware l, and the wall panel 5 is fixed on the foundation 2 with the floor panel 4 held between the joining hardware l. Fixed.

Therefore, an external load, such as a shearing force, applied to the wall panel 5 can be smoothly transmitted to the floor panel 4 via the joining hardware l.

In addition, if a mouth-shaped reinforcing rib 15 is fixed to the body 11 of the joining hardware l, the joining hardware l will be removed by an external load from the wall panel 5.
However, the fixing nut 32 can be screwed onto the anchor port 3 with sufficient torque without deformation, buckling, etc.

FIG. 4 is an exploded perspective view showing the main structure of the floor panels 4a and 4b joined to the wall panel 5 in abutted state.

This joining structure differs from the joining structure explained in FIG. 2 in that the butt portions of the floor panels 4a and 4b are not fixed to the foundation, but only the floor panels 4a and 4b and the wall panel 5 are joined to each other. It is something.

First, the floor panels 4a and 4b are placed at required positions on the cloth foundation 2, facing each other. Then, place the upper piece 12 of the joining hardware 1 on both sides panels 4a and 4b so that the frame is passed, and
1 are brought into contact with the side end surfaces 41a and 43b of both panels and nailed, respectively. As a result, the floor panels 4a, 4b are connected to the upper end surfaces 42a, 42b by the upper piece 12, and the side end surfaces 43a,
43b is in a state where it is joined by the body portion 11.

In such a state, the wall panel 5 is hung and the joining hardware 1 is
The anchor insertion hole 14 provided in the upper piece 12 and the box hardware 5
The bolt holes provided in the lower piece 3 are aligned, and the fixing port 57 is screwed onto the fixing nut 18 welded to the back surface of the upper piece 12.

By chamfering the upper part of the protruding corner at the abutting part of the floor panels 4a and 4b, the fixing nut 18 welded to the back surface of the upper piece 12 will fit into the recess formed by these chamfered parts, and the joining hardware l will be fixed. It will be placed smoothly.

Therefore, as shown in the joining cross-sectional view of FIG. 5, the floor panels 4a and 4b are integrally joined to the wall panel 5 via the joining hardware l at the butt part of the floor panels, so the wall panel 5 The external stress from the floor panels 4a, 4b is evenly distributed and transmitted to the floor panels 4a, 4b.

(Effects of the Invention) As explained above, the floor panel 4 and the wall panel 5 are firmly fixed as one body through the joining hardware l, and the floor panel and wall panel are each integrally connected by the anchor port. and fixed on the foundation. Furthermore, if joint hardware l is used at the butt portions of the floor panels, the floor panels 4,
4 can be firmly joined not only to each other but also to the wall panel 5.

Therefore, in a building using the joint structure of the present invention, external stress from the wall panels made of precast concrete is smoothly transmitted to the floor panels made of wood panels.

In particular, the shearing force from the wall panel is distributed throughout the floor panel, resulting in extremely good stress transmission. Moreover, although the shape of the joining hardware itself is extremely simple, it is made strong by the reinforcing ribs, the joining work is simple, and the overall construction cost is extremely low.
