Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a mounting structure for fixing a horizontal member such as a beam or a girder to a column in an assembled house such as a garage or a warehouse.

[Conventional technology]

As a structure for mounting the horizontal members on the columns, there is a joint system in which the horizontal members are fastened to the joint fittings that are assembled to the columns with bolts, and the horizontal members and a part of the columns are joint walls, and the intersections of the two are bolted. There is a direct method of concluding with.

Of these, the present invention belongs to the latter direct method. As one of the conventional techniques, the form shown in FIG. 10 is known (literature unknown). Here, a vertical groove 22 for joining is formed in the upper end of the pillar 21, and a horizontal member 23 is dropped into the vertical groove 22 from above to engage the pillar 21 and the horizontal member 23 with each other. Bolt 24
It is concluded with.

[Problems to be solved by the device]

In the assembled house, after temporarily assembling the frameworks such as columns and horizontal members, the inclination and distortion of each member are corrected and finally bolted.

Therefore, in the mounting structure of the horizontal member 23 as described above, when one of the members is fitted into the vertical groove 22 and the other is incorporated into another column, the horizontal member 23 is likely to slip out from the vertical groove 22, and There was a problem in that it was difficult to do the work alone.

Further, since the column 21 and the horizontal member 23 are connected only by the bolts 24 and there is no surface-joint portion unlike the joint method, rattling is likely to occur even after the final tightening. In particular, a shear load is concentrated on the bolt 24 with respect to an external force along the longitudinal direction of the horizontal member 23, which is disadvantageous in that the robustness is not sufficiently obtained.

The present invention has been proposed in order to solve the above conventional problems, and its purpose is to improve the workability of assembling the horizontal members by improving the mounting structure of the horizontal members, and at the same time, to improve the structure of the frame structure. To improve the robustness of.

[Means for solving the problem]

FIG. 1 and FIG. 2 explain the principle of the present invention in principle. For connecting and fixing the horizontal member 2 to the hollow pillar 1, the mounting wall 10 of the pillar 1 to which the horizontal member 2 is joined is fixed. A bottomed groove 11 is formed in the vertical direction, and a connecting piece 7 that fits into the bottomed groove 11 is formed at the end of the vertical wall 5 of the horizontal member 2 and a retaining piece that fits into the pillar 1. It is a requirement that the joint portion 8 fixed by 1. is integrally formed continuously.

More specifically, the joint portion 8 is connected to the connecting piece 7 and is in contact with the inner wall surface of the column 1 so that the horizontal member 2 has the bottomed groove.

That is, the joint portion 8 includes a retaining piece 12 that is connected to the connecting piece 7 in an orthogonal state, and joining pieces 13 and 14 that are connected to the retaining piece 12 and are bolted to the inner surface of the column 1 in a surface contact state. Become.

[Action]

When the connecting piece 7 is dropped into the bottomed groove 11 and engaged, the joint portion 8 on the tip side of the connecting piece 7 fits into the column 1. Even if an external force in the longitudinal direction acts on the horizontal member 2 in this temporarily assembled state, the joint portion 8, specifically, the retaining piece 12 contacts the inner surface of the column 1 and opposes the external force. 2 can be prevented from falling off the pillar 1.

Then, the pillar 1 and the joint portion 8 fitted to the pillar 1 are bolted to each other.
Use this to fix the book. Specifically, the joint pieces 13 and 14 of the joint portion 8
Is joined to the inner surface of the pillar 1 in a surface contact state, and is fully tightened by the bolt 18 without backlash.

(First Embodiment) FIGS. 3 to 6 show a first embodiment in which the present invention is applied to a warehouse.

FIG. 3 shows the frame structure of the warehouse, which is a hollow pillar 1 erected on the foundation and the upper and lower ends of each pillar 1,
The skeleton is composed of the upper and lower upper frames 9 and 9 which are one of the horizontal members and the middle girder 2 and the left and right beams 3 which are the other horizontal members which are passed between the upper and lower ends of each pillar 1. There is. Each of the columns 1 is made of a hollow metal material having a rectangular cross section, and the lower end thereof is temporarily fixed to the anchor plate 4 with a bolt (not shown). The mounting structure of the present invention is applied to each of the connecting portions P1 and P2 of the girder 2 and the pillar 1. Hereinafter, the relevant girder 2 will be described by reading it as a horizontal member.

In FIG. 4 and FIG. 5, the horizontal member 2 in the figures is composed of a pair of front and rear channel members 2a and 2b having a C-shaped cross section, and the vertical walls 5 and 5 of the respective channel members 2a and 2b are joined back to back, The joints are integrated by fastening them with bolts 6.

Joint portions 8 are integrally formed on both ends of each vertical wall 5 of the respective channel members 2a and 2b via connecting pieces 7.

A vertical bottomed groove 11 is formed on the mounting wall 10 of the pillar 1 to which the horizontal member 2 is joined, starting from the opening upper end of the pillar 1, and the connecting piece 7 is placed above the bottomed groove 11. The basic specifications are such that the entire fitting portion 8 is fitted into the pillar 1 when the fitting is dropped into the pillar 1.

The connecting piece 7 is formed by directly extending the vertical wall 5 with a margin length larger than the thickness of the mounting wall 10 on the side of the pillar 1.

The joint portion 8 is a retaining piece 12 that is connected to the connecting piece 7 in an orthogonal state.
And the two joining pieces 13 and 14 are bent and formed in a U shape in a plan view.

In the connecting portion P1 at the left and right ends, as shown in FIG. 4, the left-to-right distance between the retaining piece 12 and the joining piece 14 opposed thereto is set to be smaller than the left-to-right facing distance on the inner surface of the pillar 1, and Screw holes 15 are provided at two positions above and below 13 and 14. Also, on the wall surface of the pillar 1 corresponding to both joint pieces 13 and 14, screw holes
A bolt hole 16 is provided in a penetrating manner corresponding to 15.

In order to position the screw hole 15 and the bolt hole 16, the fifth
As shown in the figure, a positioning groove 17 is formed in the lower end of the connecting piece 7. That is, when the connecting piece 7 is dropped into the bottomed groove 11 and the positioning groove 17 is fitted in the bottom of the bottomed groove 11, the centers of the fastening holes 15 and 16 are aligned. However, the positioning groove 17 may be omitted, and the centers of the fastening holes 15 and 16 may be aligned with each other with the joining piece 14 in contact with the corresponding inner wall surface of the column 1.

At the intermediate connecting portion P2, as shown in FIG.
Horizontal members 2 are connected in a straight line on the left and right sides of. for that reason,
The corresponding pillar 1 has a rectangular cross section with left and right sides, and has bottomed grooves 11 and 11 on its left and right walls, respectively, and has screw holes 15 so that the retaining pieces 12 of each joint part 8 can be used as joint pieces. The retaining piece 12 is also formed, and corresponding bolt holes 16 are provided in the left and right mounting walls 10, 10.

Next, a procedure for assembling the horizontal member 2 with respect to the pillar 1 will be described.
The front and rear channel members 2a and 2b are integrally fastened with bolts 6 prior to the assembly of the horizontal member 2.

First, connect the connecting piece 7 on one end side of the horizontal member 2 to the pillars 1 on the left and right end sides.
Hook the bottomed groove 11 from above. At that time, since the whole of the horizontal member 2 is obliquely inclined, only a part of the lower end of the joint portion 8 fits inside the pillar 1, and the lower end surface of the retaining piece 12 contacts the inner surface of the mounting wall 10. Hitting When the other end of the horizontal member 2 is lifted in this state, the joint portion 8 gradually slides into the column 1 due to the fitting guide action of the bottomed groove 11 and the connecting piece 7.

When the other end of the horizontal member 2 is lifted and operated, the horizontal member 2
The force that tends to come off toward the side of the middle pillar 1 acts on this, but after the connecting piece 7 is hooked on the bottomed groove 11,
12 does not come into contact with the inner wall surface of the pillar 1 and the horizontal member 2 does not fall off the pillar 1 at the end. Of course, even when a tensile force is applied by the worker, this hooked state is maintained.

When the connecting piece 7 is dropped into the bottomed groove 11 of the middle pillar 1, and then slightly moved to the pillar 1 side at the entire end of the horizontal member 2, the positioning groove 17 at the bottom of the connecting piece 7 is closed. It fits into the groove bottom of 11 and has a screw hole 15 and a bolt hole at the end connection P1.
The 16 hole centers coincide. In this state, bolts 18 are screwed into the screw holes 15 from the outer surface of the column 1 through the bolt holes 16 as needed to temporarily fix the joint portion 8 to the column 1. Similarly, at the intermediate connecting portion P2, the joint portion 8 is temporarily fixed to the column 1. In this state, the pillar 1 and the horizontal member 2 will not come off even if the bolt 18 is not temporarily fixed.
In FIG. 3, the right end of the right cross member 2 is also connected to the right pillar 1 with the same specifications so that the right end is also symmetrical.

Thus, all the horizontal members (the upper frame 9 and the girder 2) are mounted between the left and right columns, and are mounted between the columns 1 before and after the beam 3 in a predetermined manner and temporarily tightened. After the skeleton has been assembled, the brace is attached and the turnbuckle is tightened to optimize the assembling postures of the pillar 1, the girder 2 and the beam 3, and all the bolts 18 are fully tightened to complete the skeleton.

In this fully tightened state, the horizontal member 2 and the pillar 1 are joined pieces.
Surface contact is made via 13 and 14, and these surface contact portions are fastened by bolts 18. Therefore, even when an external force along the longitudinal direction acts on the horizontal member 2, there is no backlash between the horizontal member 2 and the pillar 1.

[Second Embodiment] Fig. 7 shows a second embodiment of the present invention. In this case, the horizontal member 2 has the lower edge 7a of the connecting piece 7 extending from the vertical wall 5 to the joint portion 8.
And the end 19a of the upper L-shaped reinforcing piece 19 bent and extended from the upper end of the vertical wall 5 is formed so as to increase the cross-sectional area of the connecting piece 7, and the end 19a of the lower L-shaped reinforcing piece is formed. 19
It is made closer to the side of the retaining piece 12 than that, so that the strength of the connecting piece 7 is improved and the joint portion 8 can be smoothly slid into the column 1 at the time of assembling by the lower edge 7a.

[Third Embodiment] FIG. 8 shows a third embodiment of the present invention, in which a connecting piece 7 is extended and formed, and a retaining piece 12 bent and bent at a right angle is bolted at the same time. Joining piece 14
Thus, the joint portion 8 is constituted only by the retaining pieces 12.

[Fourth Embodiment] FIG. 9 shows a fourth embodiment of the present invention, in which two joining pieces 13 and 14 are continuously connected to the connecting piece 7 by bending them into an L-shape. The joining piece 13 has a structure which also serves as the retaining piece 12. Further, the pillar 1 is made of a channel material having a C-shaped cross section.

[Another embodiment example]

In addition to the above, the horizontal member 2 may be formed of a single channel member as shown in FIG. 1, the sectional shape including the vertical wall 5 is not limited, and the positioning groove 17 can be omitted.

It goes without saying that the present invention can be applied to a case where a beam is attached to a column as a horizontal member.

The bottomed groove 11 can also be formed in the middle of the pillar 1. In this case, an opening for inserting the joint portion 8 into the column 1 may be continuously provided above the bottomed groove 11. The pillar 1 is also not particularly limited to have a circular cross section or a semicircular cross section. Column 1 and joint 8
The spots may be fixed by spot welding or the like.

[Effect of device]

As described above, in the present invention, the connecting piece 7 and the joint portion 8 are formed at the end of the horizontal member 2, and the connecting piece 7 is provided with the bottomed groove of the column 1.
Since the joint portion 8 is fitted into the inner surface of the pillar 1 to be received and supported by being dropped into 11, the joint portion 8 can be supported even when the horizontal member 2 receives an external force along the longitudinal direction during assembly. 8 can be received by the inner wall surface of the pillar 1, and the horizontal member 2 can be reliably eliminated from falling off from the pillar 1. Therefore, the horizontal member 2 can be easily and surely assembled to the pillar 1, and the assembling workability can be improved. In particular, even when the skeleton is constructed by one worker, the horizontal member 2 can be assembled accurately and quickly, and the horizontal member 2 does not fall out even in the temporarily assembled state, which is advantageous in terms of safety.

Further, the connecting piece 7 and the joint portion 8 are provided at the end of the vertical wall 5 of the horizontal member 2.
Since and are integrally formed, unlike the formation in which the connecting piece 7 and the joint portion 8 are separately formed and subsequently attached, the number of members and the number of assembling steps can be suppressed to a necessary minimum.
Inexpensive and easy to construct.

When the joint pieces 13 and 14 are provided on the joint portion 8 and the inner wall surfaces of the pillar 1 are brought into surface contact with each other and fastened with the bolts 18, the pillars of the joint portion 8 are added in addition to the tightening force of the bolts 18. The total force of the frictional resistance with 1 and the mechanical structural deformation resistance can resist a large external force, which is advantageous in eliminating rattling at the connection portion and improving the robustness of the assembled house.
