A large-area curtain wall steel keel installation method

Abstract

The invention discloses a large-area curtain wall steel keel installation method, comprising the following steps: preparing several main pipes, several surface layer steel keels, several corner codes and several bolts, and a long strip-shaped adjustment hole is arranged in the center of the horizontal side and the adjustment hole is vertical The connecting line on the vertical and horizontal sides; then open a connection hole on the upper side or / and lower side of the main pipe corresponding to each fixed point; fix the corner code on the main pipe, and ensure that the vertical side of the corner code is facing outward And the inner surface of the vertical side is far away from the main pipe for a certain distance, and then the main pipe is fixed on the wall surface; the surface steel keel is welded to the outer surface of the vertical side of the corner code, and then the total station is used to detect that the surface steel keel is located at the position of the corresponding main pipe The coordinates of each point; if the error between the point coordinates and the design point coordinates is greater than 5mm, then screw the corresponding angle code to drive the surface steel keel to move to adjust the coordinates of each point, and then tighten the bolts. The method can adjust the radian error of the steel keel on the surface layer of the curtain wall, and improve the installation accuracy of the steel keel on the surface layer of the curtain wall.

Description

technical field [0001] The invention belongs to the technical field of building steel structure construction, and in particular relates to a large-area curtain wall steel keel installation method. Background technique [0002] Large-area curtain walls are generally standard equipment for large venues, theaters and other buildings, and their structures are generally steel structures. Large-area curtain walls include main frames, surface steel keels and LED displays, and the main frame and surface steel keels constitute the curtain wall. Steel keel. Generally, the main frame is welded and fixed on the steel structure wall of the building, the surface steel keel is welded and fixed on the main frame, and the LED is fixed on the surface of the surface steel keel. The main frame is generally made of H-shaped steel, channel steel and other materials, and the surface steel keel is made of thin-walled square tube or rectangular tube. The main frame is generally composed of several ...

Problems solved by technology

However, since the steel is easy to deform after welding, especially the steel keel on the surface layer requires thin-walled square tubes, it is prone to concave-convex deformation after welding, which greatly affects the forming accuracy of the surface wall surface layer. If the surface layer of the curtain wall is in a flat shape, it is easy to cause the curtain wall The surface layer is uneven; if the surface layer of the curtain wall is a curved shape, it is easy to cause changes in curvature, uneven radians, or even waves, which will affect the quality and appearance of the project
