Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a frame structure in which beams or foundations are attached to columns in a wooden house.

[Conventional technology]

In the conventional framework structure, a groove is bored in the part of the column where the beam or the base is attached, and a protrusion is formed on the end face of the beam or the base to fit into the groove of the column or the base. The beam or foundation was fixed to the pillar by fitting into the groove of the pillar and inserting nails or bolts into the pillar from the beam or foundation side.

[Problem to be solved by the invention] By the way, in the conventional frame structure described above,
After fitting the beam or the protrusion of the foundation into the groove of the column, the two are only fixed with nails or bolts, which causes problems in terms of strength because the fixing force between the column and the beam or the foundation is weak.

The present invention aims to solve the above-mentioned problems, and its purpose is to fix an abbreviated support fitting to the column in advance in the groove part formed in the column, and to use this support fitting. Since the protrusion of the beam or foundation fits into the groove of the column, it is very easy to fit the beam or foundation to the column, shortening the construction period, and it is also easy to fix the beam or foundation to the column. In addition, since the beams or foundations are fixed using fixing fittings with bolts inserted in one piece, the columns and beams or foundations can be more firmly fixed by the cooperation with the supporting fittings. It is also an object of the present invention to provide a framework structure that allows for easy attachment of fixing fittings to beams or foundations.

(Means for Solving the Problems) The present invention relates to a frame structure for achieving the above-mentioned object, and the means includes forming a groove on the surface of the column on which the beam or the base is attached, and on the other hand, the end surface of the beam or the base In a framework structure in which a protrusion is formed to fit into the groove, and the protrusion is fitted into the groove to fix the beam or foundation to the column, the horizontal and vertical members are connected at right angles through reinforcing materials. An L-shape in which the vertical member of the fixed support fitting is fixed to the column, a beam or a base is fixed to the horizontal member, a bolt is fixed to one part, and a bolt insertion hole is formed in the other part. The bolts of the shaped fixing fittings are formed in a thread or a base and inserted into the holes, and the bolts are inserted into holes in the beam or base arranged at right angles to the beam or base from the bolt insertion holes of the other piece, respectively. The gist is that the bolts and nuts are tightened to secure the base or base to the pillar.

[Function] In the framework structure of the present invention, the vertical members of the support fittings are attached close to the grooves of the columns, the beams or foundations are attached to the horizontal members of the support fittings, and then the vertical members of the support fittings are attached to the horizontal members of the support fittings. Insert the bolt of the fixing fitting into one side, and insert the bolt into the other beam or foundation through the bolt insertion hole of the fixing fitting,
By screwing nuts onto each bolt and tightening them, the beams or foundations are fixed to the pillars, and the beams and the foundations are also secured to each other.

[Embodiments of the invention]

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

Figure 1 is a perspective view showing the state in which the composite beam 2 is attached to the column 1, and the flat part of the column 1 where the end face of the composite beam 2 is attached has a groove 1.
a is formed at an appropriate depth.

Further, the composite beam 2 is composed of long horizontal members 2a and square members 2b interposed at desired intervals between the horizontal members 2a, and the horizontal members 2a and the square members 2b are integrated by bolts and nuts 3. . A projection 2C that fits into the groove 1a of the pillar 1 is formed at the end of the composite beam 2 configured in this way.

Reference numeral 4 denotes a support metal fitting composed of a horizontal member 4a, a vertical member 4b, and a reinforcing member 4c, and the vertical member 4b is perpendicular to the horizontal member 4a at a position slightly shifted from the end of the horizontal member 4a. It is fixed by means such as welding, and triangular reinforcing members 4C are fixed at the corners by means such as welding. Further, a bolt insertion hole 4a+ is formed on the tip side of the horizontal member 4a, and a large number of small holes 4az for inserting nails are formed, and a small hole 4b for inserting a nail is also formed in the vertical member 4b. , are formed in large numbers. Note that the length of the projecting piece 4a3 of the horizontal member 4a that protrudes from the vertical member 4b is the length of the pillar 1.
The length is approximately the same as the depth of the groove 1a.

Reference numeral 5 denotes an L-shaped fixing fitting for fixing to the sides of the orthogonal composite beams 2 with bolts and nuts; a bolt 5a is fixed to one piece by means such as welding, and the other piece is used to insert the bolt. A bolt insertion hole 5b is formed.

Next, using the support metal fittings 4 and the fixing metal fittings 5, the composite beam 2
The construction method for attaching it to pillar 1 will be explained.

First, the projecting piece 4az of the support metal fitting 4 is inserted and placed on the lower surface of the groove 1a formed in the column 1, and the support metal fitting 4 is fixed to the pillar 1 by driving a nail through the small hole 4b+ of the vertical member 4b. This support metal fitting 4 is fixed to all the surfaces on which the composite beam 2 is attached by the same method as described above. Next, the protrusion 2C of the composite beam 2 is fitted into the groove 1a of the column 1 with the end of the composite beam 2 placed on the support metal fitting 4 as a support. Thereby, even if the composite beam 2 is heavy, the projection 2C can be easily fitted into the groove la.

In this way, with the protrusion 2C of the composite beam 2 fitted into the groove 1a of the column 1, the bolt 3 is inserted into the bolt insertion hole 4a of the support fitting 4 through the bolt insertion hole 2d formed in the composite beam 2.
+ and secure with a nut. Furthermore, the support metal fittings 4
Drive a nail into the small hole 4a of the horizontal member 4a to form the composite beam 2.
By fixing it to the column l, the vertical load applied to the composite beam 2 is supported by the fitting between the protrusion 2C and the groove 1a and the support metal fitting 4, and the horizontal load is supported by bolts and nails. Although it is supported, the strength is insufficient if it is supported only by this support metal fitting 4.

Therefore, in the present invention, the composite beams 2 are fixed with a metal fitting 5.
By connecting them, we aim to strengthen the strength against horizontal loads.

That is, the bolt 5a of the fixture 5 is inserted into the bolt insertion hole 2e of one of the adjacent composite beams 2 fixed to the column 1, and the NAND is screwed and fixed, and then the bolt 5a of the other composite beam 2 is inserted into the bolt insertion hole 2e of the other composite beam 2. Then, insert the bolt 3 through the bolt insertion hole 5b of the fixing fitting 5, and screw the nut to fix it. With this configuration, attachment of the fixture 5 to the composite beam 2 becomes very easy, and since the composite beams 2 are connected to each other, the strength against horizontal loads is increased.

FIG. 2 is a perspective view showing how the column 1 is attached to the base 6. Like the composite beam 2 in the above embodiment, the base 6 is also composed of horizontal members 6a and square members 6b, and the column 1 and the composite base A supporting metal fitting 4 is installed between the composite bases 6, and a fixing metal fitting 5 is installed between the composite foundations 6.
Since the configuration is substantially the same as that of the embodiment shown in FIG. 1 described above, the explanation will be omitted.

〔Effect of the invention〕

As described above, in the present invention, an abbreviated support fitting is fixed to the column in advance in the groove part formed in the column, and the projection of the beam or the base is fitted into the groove of the column using this support fitting. This makes it very easy to fit the beam or foundation to the column, the beam or foundation is securely fixed to the column, and the bolts can be inserted in one piece between the beams or the foundation. Since it was fixed using the fixing metal fittings, the column and the beam or the foundation could be more firmly fixed by the cooperation with the supporting metal fittings, and the work of attaching the fixing metal fittings to the beam or the foundation was very easy. This has the advantage of being able to shorten the construction period by attaching via the support metal fittings.
