Abstract

(57) [Summary] [Purpose] A brace mounting structure that does not require the use of a lattice beam to attach a brace and that tension is not applied to the lattice beam. [Structure] The brace attachment hardware 7 is fixed to the outer surface of the pillar 1. A brace mounting hole 7 is provided on the brace mounting hardware 7 and a brace mounting hole 9 is provided on the mounting flange 8. The end of the lattice beam 4 is attached to the outer surface of the pillar 1 on the upper side of the brace attachment hardware 7. One end of the brace 2 is joined to the brace mounting hole 9 of the brace mounting hardware 7. It is not necessary to attach the brace 2 using a lattice beam. Make sure that no tension acts on the lattice beam 4.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a brace mounting structure for a column in a steel frame building.

[0002]

[Prior art]

 A pillar 1 of a steel frame structure is formed by a steel pipe, and a brace 2 is used to increase the strength of the structure between the pillars 1. As shown in FIG. 3, the structure in which the brace 2 is attached to the outer surface of the pillar 1 is such that the end plate 3 is provided at one end of the lattice beam 4 and is attached to the outer surface of the pillar 1, and the flange 14 protruding from the end plate 3 is provided with a hole. It was formed by mounting one end of the brace 2 provided with the plate 6 in this hole 5 with the plate 5.

[0003]

[Problems to be solved by the device]

 However, the hole 5 provided in the flange 14 protruding from the end plate 3 of the lattice beam 4 may be used for other purposes such as attaching a bundle, and in that case, the braces 2 cannot be attached. was there. There is also a problem that the tension of the brace 2 acts on the lattice beam 4, so that an unreasonable force may be applied to the lattice beam 4.

The present invention has been made in view of the above points, and provides a brace mounting structure in which it is not necessary to attach a brace using a lattice beam, and tension is not applied to the lattice beam. That is the purpose.

[0005]

[Means for Solving the Problems]

 In the brace mounting structure according to the present invention, the brace mounting hardware 7 is fixed to the outer surface of the pillar 1, the mounting flange 8 is provided on the brace mounting hardware 7, and the brace mounting hole 9 is provided in the mounting flange 8. It is characterized in that the end of the lattice beam 4 is attached to the outer surface of the pillar 1 on the upper side of the mounting hardware 7, and one end of the brace 2 is connected to the brace mounting hole 9 of the brace mounting hardware 7. is there.

[0006]

[Action]

 Brace provided on the mounting flange 8 of the brace mounting hardware 7 fixed to the pillar 1 By connecting the brace 2 provided with the plate 6 to the mounting hole 9 it is possible to directly attach the brace 2 to the pillar 1 with the brace mounting hardware 7. .

[0007]

【Example】

 Hereinafter, the present invention will be described in detail with reference to embodiments. The brace mounting hardware 7 is formed of a metal piece having an L-shaped fixing piece 10 in plan view and a mounting flange 8 horizontally protruding from the upper end thereof. The length of one side of the fixing piece 10 is approximately the same as the width of one side of the column 1, and the brace mounting hole 9 is formed in the L-shaped corner portion of the mounting flange 8.

The lattice beam 4 is formed of a pair of upper and lower chord members 11 and a web member between the chord members 11. An end plate 3 provided with a flange 14 is attached to one end of the lattice beam 4. The brace 2 is formed of a round steel 13 and a turnbuckle 12, and a plate 6 is provided at the end thereof. The turnbuckle 12 is provided in the middle of the brace 2, and the length of the brace 2 can be adjusted by rotating the turnbuckle 12.

When mounting the brace mounting hardware 7, as shown in FIG. 2, a fixing piece 10 is provided so as to project the mounting flange 8 at a right angle from the surface of the pillar 1 and to straddle two sides of the outer surface of the pillar 1. Then, a bolt (not shown) is screwed into the pillar 1 from the through hole 17 of the fixing piece 10 so that the pillar 1 is firmly fixed. The lattice beam 4 can be mounted by butt-fitting the pillar 1 at a right angle and temporarily placing it on the mounting flange 8 of the brace mounting hardware 7, and driving the bolt 15 from the end plate 3 to the pillar 1.

When the brace 2 is attached, the brace attachment hole 16 of the plate 6 attached to one end of the brace 2 as shown in FIG. 1 is provided in the attachment flange 8 of the brace attachment metal 7 fixed to the pillar 1. The braces 2 can be directly attached to the columns 1 by the brace attachment hardware 7 by connecting the brace attachment holes 9 with bolts and nuts (not shown).

[0011]

[Effect of device]

 As described above, according to the present invention, the brace mounting hardware is fixed to the outer surface of the pillar, the mounting flange is provided by projecting on the brace mounting hardware, and the brace mounting hole is provided on the mounting flange, and the brace mounting hardware is provided above the brace mounting hardware. Since the end of the lattice beam was attached to the outer surface and one end of the brace was connected to the brace mounting hole of the above brace mounting hardware, the brace can be directly attached to the pillar with the brace mounting hardware, and the brace can be used with the lattice beam. It is not necessary to attach it to the lattice beam, and it is possible to prevent tension from acting on the lattice beam. In addition, by temporarily placing the lattice beam on the brace mounting hardware, it is possible to easily attach the lattice beam to the column using the brace mounting hardware.
