Abstract

(57) [Summary] [Purpose] Construct a joint between an SRC column or RC column and a steel beam so that it is easy to place column concrete and the concrete fits well. [Structure] A double beam A is constructed by placing two channel steels 1 back to back. With these two channel steels 1, SRC
(Steel reinforced concrete) Double beam A is joined to column B with column B sandwiched between them. Double beams A' are joined in a parallel cross pattern so as to be orthogonal to double beam A.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention applies to columns and beams, especially RC (reinforced concrete) columns or SRC (steel-framed steel columns). Concerning the structure of the joint between reinforced concrete (reinforced concrete) columns and steel beams.

0002

[Conventional technology]

As shown in Figure 4, the structure of the joint between a conventional SRC column and a steel beam is as follows: The beam steel frame D was integrally welded to the steel frame C. In this way, in the conventional structure, Figure 5 As is clear from the figure, a part of the beam steel frame D has entered the column formwork 6, so the column When pouring concrete, this beam steel frame D will get in the way of concrete filling. It is difficult to pour the concrete, and the concrete is not well-contained, and the horizontal position of the steel column C. There were problems such as the stiffener 7 preventing concrete filling.

0003

[Problem that the idea aims to solve]

This invention was devised to solve the above conventional problems, and its purpose is to Places where it is easy to place column concrete, and the concrete is placed very tightly. The object of the present invention is to provide a column-beam joint structure that can be improved.

0004

[Means to solve the problem]

The column-beam joint structure of this invention consists of double beams assembled back-to-back. The special feature is that the SRC column or RC column is joined in a sandwiched state by two channel steels of the column. be a sign. In addition, an intermediate stiffener is attached to the outer surface of the groove steel web at the above joint, Studs are installed on the inner surface of the channel steel web at the joint, and then fixed in the concrete of the column. It is also characterized by being dressed up.

[0005]

【Example】

An embodiment of the present invention will be described below with reference to the drawings. In Fig. 1, 1 is a channel steel, and two of these are placed back to back to form a double bead. It constitutes the system A. B is an SRC (steel reinforced concrete) column, which is a steel column. It is constructed by pouring reinforced concrete 3 around 2. double beam A and S At the joint with RC column B, SRC column B is sandwiched between two channel steels 1 of double beam A. It's a scramble. At the joint, there is a double beam perpendicular to the double beam A. Beam A' is joined in a grid pattern, and two sets of double beams A and A' take SRC column B. It is assembled integrally so as to surround it.

[0006] As is clear from FIGS. 2 and 3, the outer surface of the web of the channel steel 1 at the joint section is The intermediate stiffener 4 is integrally welded. 5 is a stud, which connects the The reinforced concrete 3 of the SRC column B is planted on the inner surface of the web of the channel steel 1 at the joint. The double beams A and A' are integrally connected to the SRC column B. Ru.

[0007] In the above embodiment, the connection between the SRC column and the double beam was explained, but in this case, The proposal is not limited to this, but includes RC (reinforced concrete) columns and double beams. It may also be a bonded structure with a rubber band. In addition, the cross-sectional shape of the pillar is limited to the square mentioned above. It can be any shape, such as a rectangle, polygon, circle, etc.

[0008]

[Effect of the idea]

1) Since there is no reinforcing steel for the beam inside the column, it is easier to place concrete for the column. It fits well. 2) Easy construction and cost reduction. 3) The space between the double beams can be used as a space for equipment piping.
