Example of Invention

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a state where a composite beam 2 is attached to a pillar 1, and a groove is formed on each adjacent surface of the pillar 1 having a predetermined width.
1a is formed with an appropriate depth, and the end face of the composite beam 2 having the same width as the predetermined width is attached to each surface. Further, an elongated hole 1a2 communicating with the floor 1a1 at the bottom of the groove 1a and extending in the direction of the core of the pillar 1 is formed. In addition, the composite beam 2 is a long horizontal member 2a and the horizontal member 2a.
The horizontal members 2a and the horizontal members 2b are integrated with each other by bolts and nuts. At the end of the composite beam 2 configured in this way, a projection 2c that fits into the groove 1a of the beam 1 is formed. In addition, a T-shaped groove 1b is formed on the top surface of the pillar 1, and a linear groove 2d communicating with the groove 1b of the pillar 1 is formed on the top surface of the composite beam 2 to form the groove 1b. It becomes a T-shaped groove due to 2d.

4 is formed of a T-shaped hard metal plate in a plan view, and a T-shaped reinforcing piece 4a is fixed to the lower surface by welding or the like to form a mounting metal fitting, and a bolt is inserted from the reinforcing piece 4a to the tip side. The hole 4b is formed.

Reference numeral 5 is a support metal fitting composed of a horizontal plate-shaped portion 5a, a vertical plate-shaped portion 5b and a reinforcing member 5c, and the vertical plate-shaped portion 5b is connected to the horizontal plate-shaped portion 5a. A long portion and a short portion are formed in the horizontal plate-shaped portion 5a by fixing them at a right angle in the vicinity of the end portion of the horizontal plate-shaped portion 5a, and the long portion and the vertical plate-shaped portion of the horizontal plate-shaped portion 5a are formed. A triangular reinforcing material 5c is fixed between the 5b by means such as welding. Therefore, the short portion has a shape as a projecting piece in the structure of the support fitting. Further, a bolt insertion hole 5a1 is formed on the tip side of the horizontal plate-like portion 5a, and a plurality of small holes 5a2 for inserting nails are formed, and a small portion for inserting nails is also formed in the vertical portion 5b. Hole 5b
Many 1 are formed. In addition, the length of the short portion of the horizontal plate-like portion 5a projecting from the fixing portion of the vertical plate-like portion 5b to the horizontal plate-like portion 5a, that is, the protruding piece portion 5a3 is the floor portion 1 of the groove 1a of the pillar 1.
The length is formed to be approximately the same as the sum of the depth of a1 and the depth of the hole 1a2 communicating with the floor 1a1.

Reference numeral 6 is an L-shaped fixing metal fitting for fixing to the side surfaces of the composite beams 2 orthogonal to each other with a nail.

Next, the composite beam 2 is attached using the mounting bracket 4 and the supporting bracket 5.
A construction method for attaching the to the pillar 1 will be described.

First, as shown in FIG. 3, the floor of the groove 1a formed in the pillar 1
From 1a1, the short part of the support fitting 5, that is, the tip of the projecting piece 5a3 is made into a long hole.
The short portion is placed on the floor portion 1a by inserting it into the inside of 1a1, and the nail is driven through the small hole 5b1 of the vertical plate portion 5b shown in FIG. This support fitting 5
Is fixed to all the surfaces to which the composite beam 2 is attached by the same method as described above.

Next, the pillar 1 is erected on a base (not shown), and the supporting metal fitting 5 is placed on the bottom 1a1 of the groove 1a and the short portion thereof, that is, the tip of the projecting piece 5a3 is inserted into the long hole 1a2. As a result, the projection 2c of the composite beam 2 is fitted into the groove 1a of the column 1 with the end portion of the composite beam 2 placed thereon. As a result, the projection 2c can be easily fitted into the groove 1a even if the composite beam 2 has a large weight, and the horizontal plate-shaped portion 5a of the support fitting 5 is not protruded.
Since 3 is inserted up to the long hole 1a2 of the pillar 1, the support fitting 5 does not come off from the pillar 1 even if a vertical load is applied to the horizontal plate portion 5a.

In this way, in the state where the projection 2c of the composite beam 2 is fitted in the groove 1a of the pillar 1, the reinforcing piece of the mounting member 4 is fitted into the grooves 1b and 2d formed on the top surface of the pillar 1 and the top surface of the composite beam 2. 4a is fitted, and a bolt is inserted from the bolt insertion hole 4b of the mounting bracket 4 through the bolt insertion hole 2e of the composite beam 2 to the bolt insertion hole 5a1 of the support bracket 5.
And fix with nuts. Further, by nailing the nails through the small holes 5a1 of the horizontal plate-like portion 5a of the support fitting 5 to fix the composite beam 2 to the pillar 1, the projection 2c and the groove 1a are not affected by the vertical load applied to the composite beam 2. It is supported by the fitting and support fitting 5, and is supported by bolts and nails for horizontal load.

In addition, the composite beam 2 fixed to two adjacent surfaces of the pillar 1
By fixing the L-shaped fixing metal fittings 6 with nails, the corners between them are more firmly fixed to the pillar 1 because the composite beams 2 are integrated with each other.

〔The invention's effect〕

According to the present invention, as described above, through the groove into which the projection of the beam having the projecting piece projecting from one end of the horizontal plate-like portion of the support fitting is fitted, the elongated hole communicating with this groove is provided. Since it is inserted and fixed, the end of the beam is supported when the projection of the beam is fitted in the groove, so the work of fitting the beam is very easy, shortening the construction period and lowering the wage. Since the projecting piece of the horizontal plate-shaped portion of the support fitting is inserted into the elongated hole communicating with the floor of the groove of the pillar, the support fitting is removed from the pillar even if a vertical load acts on the support fitting. The beam can be surely supported without coming off, and the columns are fixed to each other by using the support fittings, so that the beam can be firmly fixed to the column. . Furthermore, since the columns and beams have almost the same size, L-shaped fixing brackets can be used at the corners formed by the composite beams that are fixed to the two adjacent faces of the columns, and the fixation between the composite beams can be performed firmly. It is possible to obtain an extremely large effect that the strength of the entire column and beam frame structure is dramatically increased due to the integration.
