Therefore, the bent portion 3c may be expanded and deformed by the load. Therefore, the wall thickness of the fixed plates 3m and 3b should be increased, or other reinforcing plywood should be added. There must be. Therefore, the beam holder had a problem in terms of an increase in the product cost of the hardware 3.

In addition, the conventional beam support uses hardware 3 and the wall panel 1% l
When assembling the floor panel 9 onto the upper part of the floor panel 9, as shown in FIG. It is necessary to form a notch 10 for this purpose, and this work takes time and effort, creating a problem in that shortening of the construction period cannot be expected.

The present invention has been made in view of the above circumstances, and provides a beam holder that can support a beam with high yield strength, and a beam holder that can efficiently carry out the construction of a section. Uke is intended to provide structure.

[Means for Solving the Problems] The structure of the beam support according to the present invention is such that reinforcing plywood is pasted on the upper surface of the wall panels that are arranged facing each other and that constitute the wall of the building.
A fixing plate is formed by bending the plate material at right angles to the reinforcing plywood so that it comes into contact with the upper end and front surface of the reinforcing plywood, and a beam support is formed by protruding from the surface of the fixing plate that comes into contact with the front of the reinforcing plywood. The beam holder is a structure that bridges the beam by placing the end of the beam on the inside of the bent part of the plate that fixes the hardware. Ribs are formed to connect the fixed plates to each other, and a notched groove is formed on the upper end surface of the reinforcing plywood into which the other fixed plate is inserted, and a rib is inserted into the bottom of this notched groove. It is characterized by having a slit formed therein.

[Function] According to the structure of the beam support of this invention, reinforcing plywood with cutout grooves and slits is pasted on the upper part of the wall panel constituting the wall, and the wall panel is placed in a state where the reinforcing plywood faces each other. The ribs of the metal fittings are inserted into the slits of the reinforcing plywood, and the beam supports are placed in contact with the upper ends of the reinforcing plywood, and the metal fittings are fixed with screw nails. The end of the beam is placed on the beam support, and the beam is fixed by nailing the end of the beam to the reinforcing plywood with screw nails. Furthermore, the floor panel is assembled by connecting the floor panel in parallel to the beam without forming a rib relief notch in the upper end surface of the wall panel over which the beam is spanned.

[Embodiment] Hereinafter, an embodiment of the structure of the beam support of the present invention will be described with reference to FIGS. 1 to 3. Components that are the same as those shown in FIGS. 4 and 5 are designated by the same reference numerals and their explanations will be omitted.

A feature of the present invention is that the beam support used is such that the metal fittings 11 are placed inside a bent portion 11c formed by bending a plate material so that the fixing plates 11a and llb are orthogonal to each other.

A plate-shaped rib 12 is formed to connect the ttb, and the upper end surface 13a of the reinforcing plywood 13 is provided with a cutout groove 1 into which one of the fixing plates 11a is inserted and abutted.
4 is formed, and furthermore, on the bottom surface 14a of this notch groove 14, a rib! 2 is formed with a slit 15 into which it is inserted.

That is, as shown in FIG. 1, the beam support used in this embodiment has a metal fitting 11 that covers the bent portions 11b on both sides of fixed plates 11a and 11b formed by bending plate materials at right angles. A triangular plate-shaped rib 12 extending from one fixing plate 11a to the other fixing plate +ib is fixed. As a result, even if the beam support fixed to the reinforcing plywood 13 is subjected to the load of the weight 7 on the hardware 11, the two fixing plates 11g are still attached to the inside of the bent portion lie.

The ribs 13 connecting the fixing plates 11b serve as sufficient reinforcement to maintain the right angle shape of the fixing plates 11a and llb. Furthermore, as shown in FIGS. 1 and 2, a cutout groove 14 is formed in the upper end surface 13a of the reinforcing plywood 13 to which the metal fitting 11 is fixed. The radius T of this notched groove 14 is wider than the width of one of the fixed plates 11a that abuts, and the depth L thereof is set to be small (both are set to be equal to or greater than the wall thickness of the fixed plate 11a).

Further, on the bottom surface 14m of the notched groove 14, a rib 12 formed on both sides of the two fixing plates 11a and 11b is slightly wider at the top and is cut diagonally downward toward the surface 13b of the reinforcing plywood 13. A slit 15 is formed.

Next, a construction example will be described in which the beam supports fixed to the reinforcing plywood 13 having the above-mentioned structure use the hardware 11 and the beam 7 is spanned between them.

First, in a factory or the like, on the top of the wall panel 1 that makes up the wall,
A reinforcing plywood 13 in which notched grooves 14 and slits 15 are formed is pasted. Then, the wall panel 1 is transported to a construction site for a house or the like, and the reinforcing plywood boards 13 and 13 are placed facing each other so as to form a predetermined wall body. Then, the metal fittings 11 for the beam supports are attached to the upper ends 13a, 13a of the reinforcing plywood 13.13 attached to the wall panels 1.1 with fixing needles 4.
Fix it with.

At this time, the beam holder is fixed to the reinforcing plywood 13 and the metal fittings il are brought into contact with one of the fixed plates 11m inside the notch groove 14 of the reinforcing plywood 13 with the rib 12 inserted into the slit 15, so the beam holder is fixed to the reinforcing plywood 13. The hardware 11 is constructed so that it does not protrude from the upper end of the reinforcing plywood 13. Next, as shown in FIG. 3, the ends 7a of the beams 7 are placed on the beam supports 5.5 of the hardware 11.11 facing each other, and the ends 7a are reinforced with screw nails 8. The rice cake 7 is fixed by being nailed to the plywood 13. In addition, the upper end surface of the wall panel 1.1 on which the beam 7 is spanned has a conventional rib relief notch l.
A floor panel 9 is installed parallel to the casing 7 without forming an O.

As can be easily understood from the above description, in the beam support of this embodiment, the metal fittings 11 have plate-shaped ribs 12 on the inside of the bent portions 11c of the fixed plates 11a and llb.
By simply forming this, it is possible to create a structure that can sufficiently support the load of the katana 7, so that the cost for manufacturing the metal fittings 11 can be significantly reduced.

Furthermore, one of the fixing plates 11a of the hardware 11 of the beam holder fits into the cutout groove 14 formed on the upper end surface 13a of the reinforcing plywood 13, so that the metal 11 of the beam holder does not protrude from the top of the reinforcing plywood 13. Therefore, there is no need to form a notch 10 for rib escape in the floor panel 9 connected to the upper end surface of the wall panel 1.1 over which the beam 7 is spanned, as in the conventional case, and it saves time and effort. The floor panel 9 can be easily incorporated into the wall panel 1.1, the construction period can be shortened, and the construction cost can be significantly reduced.

Note that the beam support used in this embodiment has a structure in which the ribs 12 formed on the hardware 11 are provided on both sides of the fixed plates 11a and 11b, and the bent portion between these ribs 12 is Even if other ribs are provided inside the beam support, the strength of the hardware 11 can be further increased. At that time, a slit 15 formed at the bottom of the notch groove 14 of the reinforcing plywood 13 is used.
must be further formed.

[Effects of the Invention] As explained above, according to the structure of the beam support of the present invention, simply forming ribs on the inside of the bent part of the fixed plate formed by bending the plate material is enough to support the load of the beam. Since it can be made into a needleable structure, the beam holder can significantly reduce the cost of manufacturing hardware.

In addition, the other fixing plate of the beam holder hardware fits into the notch groove formed on the upper end surface of the reinforcing plywood, and the beam holder has a structure in which the hardware does not protrude from the top of the reinforcing plywood, so unlike conventional A floor panel can be easily connected to a wall panel without forming a rib escape notch in the floor panel connected to the upper end surface of the wall panel over which the beam is spanned, without taking much time and effort. It is possible to shorten the construction period, and furthermore, it is possible to significantly reduce construction costs.
