Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated building walls, in particular to a connecting structure between a green steel structure prefabricated building wall and a column. Background Art

[0002] In traditional prefabricated building walls, since the load-bearing columns are mostly concrete-cast columns with simple surface shapes, after pouring concrete later, the gripping force between the concrete and the load-bearing columns and the walls is small, and there are often problems such as insecure connection and easy cracking, which affect the overall safety and durability of the building. In the prior art, although there have been some improvement schemes, such as using anchor bars or reinforcing bars, etc., due to the requirements of assembly and installation construction, the length of the anchor bars is fixed, and the biting of the poured concrete is less, and there are still problems such as unsatisfactory connection effect. Content of the Utility Model

[0003] The purpose of the utility model is to provide a connecting structure between a green steel structure prefabricated building wall and a column in order to solve the above problems.

[0004] The utility model realizes the above purpose through the following technical solutions:

[0005] A connecting structure between a green steel structure prefabricated building wall and a column, comprising a column, a first wall, a second wall and a third wall. The column is an I-beam, and anchor bars are fixedly installed on the peripheral side surfaces of the I-beam. The first wall and the second wall are respectively butted on the left and right sides of the column, the third wall is butted on the side of the column close to the indoor side. The first wall and the second wall extend and connect with each other on the side close to the outdoor side, and the first wall, the second wall and the third wall enclose a closed space; the gaps between the column and the first wall, the second wall and the third wall are filled with concrete.

[0006] Preferably: an outer decorative layer is provided on the side surfaces of the first wall and the second wall close to the outdoor side, and a fastener is fixed at the butt joint seam position of the first wall and the second wall.

[0007] Preferably: the outer decorative layer includes an adhesive layer, a thermal insulation layer, a plastering layer and a decorative layer.

[0008] Preferably: the fastener is a decorative part.

[0009] Preferably: a first wall pouring groove is opened at the position of the first wall corresponding to the column, a second wall pouring groove is opened at the position of the second wall corresponding to the column, a third wall pouring groove is opened at the position of the third wall corresponding to the column, and the space formed by the first wall pouring groove, the second wall pouring groove and the third wall pouring groove is filled with concrete.

[0010] Preferably, anchor tie bars are also provided in the first wall casting groove, the second wall casting groove, and the third wall casting groove. One end of the anchor tie bar is embedded in the wall body, and the other end is exposed. The anchor tie bars in the first wall casting groove, the second wall casting groove, and the second wall casting groove do not extend out of the groove.

[0011] Preferably, the column is an I-beam or a square steel.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. By wrapping the load-bearing columns on the outer sides of the first wall and the second wall, the connection structure is protected from the external environment, extending its service life.

[0014] 2. By using an I-beam structure for the column, after pouring concrete, the concrete wraps the column and is connected to each wall through the cooperation of the anchor tie bars and each casting groove, greatly improving the connection strength between the wall and the column, and effectively preventing problems such as cracks caused by insecure connection.

[0015] 3. Fixing decorative parts at the joint positions on the outer sides of the first wall and the second wall not only beautifies the building appearance but also effectively covers the defects at the joints, improving the overall aesthetics.

[0016] 4. The steel structure has benefits such as not requiring rust removal, fireproof coatings, and hot and cold bridge avoidance systems. BRIEF DESCRIPTION OF THE DRAWINGS
