Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for connecting a beam to a column, and more particularly to a method for stably attaching and fixing a beam to a cross-shaped stud. It relates to a method of connecting pillars.

<Prior Art> Conventional beams or such beam connecting methods are disclosed in, for example, JP-A-63-55235 (first known technique), JP-A-63-83339 (second known technique), and No. 62-175107 (No. 3
Known techniques) and JP-A-62-175108 (fourth known technique) are known.

Among the above known techniques, a first known technique is a technique of attaching a flat splice plate to an end of a beam and attaching the beam to a connecting piece of a cross-shaped stud through the splice plate.

A second known technique is a technique of a method of bolting a T-shaped joint having a projecting portion to a flange portion to upper and lower flanges of a beam, and then contacting the flange portion to a flange of a stud.

In the third and fourth known techniques, a flat connecting plate is fixed to the end web of the beam, and this connecting plate is bolted to a connecting piece of a cross-shaped column, or is previously attached to each side surface of the stud. In this method, a connecting piece is protruded, and an end web of a beam is brought into contact with the connecting piece and bolted.

<Problems to be Solved by the Invention> However, in the above-mentioned conventional known technology, the beams and the beams or the beams and the studs are connected to each other in a flat manner via a connecting plate or the like so as to be connected. However, there is a problem that the structure is unstable and the strength is weak.

The present invention relates to a completely new technique developed in view of the above-mentioned conventional problems.

<Means for Solving the Problems> The method for connecting a beam and a column according to the present invention is a technology that fundamentally improves the above-described conventional problems, and the gist of the present invention is to provide an H-shaped beam for a cross-shaped stud. In the connecting method, an L-shaped cross-section connecting member is protruded from an end of the H-shaped beam so as to be fixed, and the L-shaped cross-section connecting member is in contact with two wall surfaces of the cross-shaped stud and bolted. Thereby connecting the H-shaped beam to the cross stud in cross section, wherein one of the bolt head or the nut is inserted into a large-diameter hole provided in another adjacent L-shaped connecting member in cross section. And how to connect the pillars.

<Operation> As described above, the method of connecting a beam and a column according to the present invention is such that an L-shaped cross-section connecting member protrudes from an end web of an H-shaped beam, and this L-shaped cross-section connecting member is a cross stud 2 Since the H-shaped beam is in contact with the wall surface, the direction and positioning of the H-shaped beam can be accurately and easily determined, and the H-shaped beam can be firmly fixed in a stable state.

<Example> A method for connecting a beam and a column according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective explanatory view showing a configuration of a method for connecting a beam and a column according to the present invention, and FIG. (B) is a front view, FIG. (C) is a side view, FIG. 3 (A) is a plan view of a beam, FIG. (B) is a side view thereof, and FIG. FIG. 4 is a horizontal sectional explanatory view showing a state in which a beam is attached to a stud.

In FIGS. 1 and 2 (A), (B), (C),
Reference numeral 1 denotes a cross-shaped stud, which is formed by joining four connecting pieces 1a in a cross-shaped cross-section, and integrally connecting upper and lower plates 2, 3 above and below these connecting pieces 1a, respectively. Have been. Each pillar 4 is connected to the lower surface of the cross-shaped stud 1.

Next, in FIGS. 1 and 3 (A), (B) and (C), reference numeral 5 denotes an H-shaped beam, which connects horizontal flanges 7 and 8 integrally on a vertical web 6. It is constituted by that. L-shaped connecting members 9 are fixed to the end webs 6 at both ends of the H-shaped beam 5 so as to project in opposite directions to each other. The L-shaped cross-section connecting member 9 has a tip panel 9b bent in a direction perpendicular to the axis of the H-shaped beam 5 integrally connected to the tip of a base panel 9a parallel to the axis of the H-shaped beam 5 in a key shape. It is constituted by.

Bolt holes 10 are respectively formed at predetermined positions of the connecting pieces 1a of the cross-shaped stud 1 and the end panel 9b of the L-shaped connecting member 9, and a predetermined position of the base panel 9a of the L-shaped connecting member 6 is also provided. Is provided with a large-diameter hole 11 into which a nut or bolt head can be inserted.

Next, when attaching the H-shaped beam 5 to the above-mentioned cross-shaped stud 1, in particular, as shown in FIGS. 1 and 4, an L-shaped cross-section connecting member projecting from an end web 6 of the H-shaped beam 5. 9, the base 9a and the end panel 9b are in contact with the wall surfaces of the two connecting pieces 1a of the cross stud 1 in cross section, respectively.
Insert the bolt 12 into the bolt hole 10
The H-shaped beams 5 can be bolted to the cross-shaped studs 1 in cross section, respectively.

Each of the plurality of H-shaped beams 5 is in stable contact with the two connecting pieces 1a of the cross-shaped stud sub-section 1 via the L-shaped cross-section connecting member 9 in the same manner as in the above-described embodiment. I can do it.

In mounting and fixing the plurality of H-shaped beams 5 side by side to the cross-shaped stud 1 via the L-shaped cross-section connecting member 9, the area of the bolt 12 or the nut 13 previously attached to the cross-shaped stud 1 is used. As shown in FIG.
It can be inserted into the large-diameter hole 11 of the base panel 9a of another adjacent cross-section L-shaped connecting member 9.

Therefore, when a plurality of H-shaped beams 5 are connected side by side to the cross studs 1 in cross section, they can be connected without interfering with each other, whereby the order of mounting the H-shaped beams 5 can be made freely. I can do it.

<Effect of the Invention> Since the method for connecting a beam and a column according to the present invention has the above-described structure and operation, the ends of the plurality of beams are respectively connected to the cross-shaped studs through an L-shaped cross-section connecting member. While being in contact with two surfaces, it can be easily positioned and attached and fixed in a firm and stable state.

Further, between the cross-shaped cross sections, up to four H-shaped beams can be connected to the column side by side with an extremely simple identical shape.

Further, according to the present invention, since one of the bolt head or the nut of the bolt used for bolting can be inserted into the large-diameter hole provided in the L-shaped cross-section connecting member and adjacent thereto, the concentrated L-shaped cross-section connecting member is concentrated. It is possible to avoid the mutual interference of the bolts that fix the bolts and to carry out the work efficiently. Therefore, the mounting procedure of each H-shaped beam can be made freely. Furthermore, such good workability has a feature that can be similarly exhibited even when the connection between the pillar and the beam is partially disconnected in a remodeling or extension of a building.
