Curtain wall metal structure vertical keel and vertical keel and transverse keel connecting structure

Abstract

The invention provides a curtain wall metal structure vertical keel. The vertical keel is a square-pipe keel. The vertical keel is characterized in that one end of the vertical keel is extruded into a joint square pipe shape, the surface of the joint square pipe shape is provided with a vertical bulge to form a plugging part of which the upper and lower cross-sectional overall sizes are consistent and which has a heat-expansion and cold-contraction compressive function and is integrated with a square-pipe keel. The plugging part can be matched with the other end of the square-pipe keel in size, so that the plugging part of a vertical keel can be plugged into the other end of a square-pipe keel through interference or transition fit. The end of the plugging part is an anti-cutting plug head. By adopting a connecting structure provided by the invention, during connection of a vertical keel and a transverse keel, the positions can be adjusted quickly and conveniently, the keels can be installed accurately, the transverse keel can adapt to heat-expansion and cold-contraction and does not shift after installation, the keels are installed firmly and never loosen, and no welding is needed.

Description

technical field [0001] The invention relates to the vertical keel of the metal structure of the curtain wall and the connection structure of the vertical keel and the horizontal keel, which is suitable for the connection of prefabricated integrated building stone, ceramics, microcrystalline stone, glass, aluminum plate, and other curtain wall keels, especially for multiple typhoons , many earthquakes, and crowded subways, stations, airports, tunnels, schools, and high-rise buildings. Background technique [0002] At present, there is no unified method for the connection between the vertical keels of the metal structure of the curtain wall. They all use a certain length of steel plate and angle steel to be inserted into the vertical keel tube at one end and connected by welding, so that the profiles outside the tube form a thermal expansion of the vertical keel. Plug for cold shrinkage; with this structure, the size of the plug is not standardized, the error is large, the dif...

Problems solved by technology

[0005] Welding is the main cause of construction fires in high-rise buildings, and in actual construction, due to the high construction intensity and harsh environment, there has been a shortage of skilled welders, and the quality of welding during installation is also a hidden danger to the quality of curtain wall buildings

With the above-mentioned keel connection structure, there is still welding construction. Due to the deformation caused by the release of welding stress, the number of accessories is increased, and the number of bolts is large, and some of the large deformations have to be reversed with oxyacetylene and then watered. The cost rises, the labor is laborious, the life is shortened, the lack of a complete set of quick installation solutions, and serious safety and fire hazards

[0006] In order to solve the frictional resistance between the wall cavities, the existing plug-in technology for round pipes adopts large-scale plug-in connections that are first wider and then tighter. The columns of the curtain wall need to be suitable for the linear expansion of the daily temperature difference. The resistance cannot be too large and cannot be loosened, and it must bear the twisting force against wind pressure, so these technologies cannot be applied to the thermal expansion and contraction of curtain wall columns and the needs of wind pressure resistance

[0007] There are two ways to process the existing column structure. After the workshop is completed, a vertical long hole is drilled on the main column. The horizontal error of the column is adjusted through the long hole, but it will loosen and slide down due to fatigue, causing the plate to fall

The other is on-site welding and on-site drilling, but the processing is rough and precise, and there are many hidden dangers
