Connection structure of construction curtain wall cross beam and pillar

Abstract

A join structure between the transverse beam and the vertical column for the curtain wall of building features that a joining part with particular shape, two or more slot openings with same direction on its one surface and a boss on the root of its another surface is fixed to vertical column via screws, the transverse beam has the slot opening the its internal cavity and with the direction different from that of the slot opening on joining part for matching them with each other, and the fastener is respectively arranged on said boss of joining part and the side wall in the internal cavity of transverse beam.

Description

Technical field: [0001] The invention relates to a building curtain wall, in particular to a connection structure between a building curtain wall beam and a column. Background technique: [0002] The connection between the crossbeam and the column of the building curtain wall in the prior art is to install the crossbeam ferrule on the pillar through screws, and the crossbeam and the ferrule are plugged in. At the same time, the convex side is cut on the crossbeam, and a hole is opened on it. The upper part of the hole is connected with the column screw (as shown in Figure 1). The disadvantage of the above structure is that the installation and processing are complicated and inconvenient. When installing the column, it must be installed with the beam at the same time; Corner code, on the crossbeam, be provided with the notch (as shown in Figure 2) of opposite direction, corner code is inserted in the slot opening and fixes; Adopt the defective of above-mentioned structure to ...

Problems solved by technology

[0002] The connection between the crossbeam and the column of the building curtain wall in the prior art is to install the crossbeam ferrule on the pillar through screws, and the crossbeam and the ferrule are plugged in. At the same time, the convex side is cut on the crossbeam, and a hole is opened on it. The upper part of the hole is connected with the column screw (as shown in Figure 1). The disadvantage of the above structure is that the installation and processing are complicated and inconvenient. When installing the column, it must be installed with the beam at the same time; Corner code, on the crossbeam, be provided with the notch (as shown in Figure 2) of opposite direction, corner code is inserted in the slot opening and fixes; Adopt the defective of above-mentioned structure to be: 1, the corner code should be cut during installation, and will be relatively accurate; 2. Before the corner code is inserted into the notch, the notches at both ends of the beam must be milled, and a part not less than the thickness of the corner code must be milled out; 3. When the corner code and the column are installed, the corner code must first be inserted into the notch of the beam together with the beam Installation, due to the limitations of the space in the inner cavity of the beam, the operation is limited when the corner bracket is connected to the column, which is inconvenient and difficult to install accurately, and it is also not easy to adjust the deviation; 4. Poor torsion resistance

There is also a way that the corner code is connected to the beam without a notch by screws. This connection method has the above-mentioned defects at the same time, and in order to meet the thermal expansion and contraction of the beam, it is necessary to mill the connecting screw holes of the beam or corner code. Long rows of holes; and corner codes and beams need to be drilled multiple times; processing and installation are more inconvenient

There is also a structure that adopts the above-mentioned corner codes and nut grooves on the crossbeam. By opening holes on the corner codes, the structure that connects the corner codes and the beam through screws and nuts is realized. This structure also has corner codes. The defects of poor torsion resistance and inconvenient installation also require multiple drillings on the corners, increasing the cross-sectional area of ​​the aluminum material, relatively increasing the cost, and inconvenient installation and adjustment.
