Description
Technical Field
The invention relates to the technical field of constructional engineering, in particular to a connecting structure of a curtain wall.
Background
At present, the connection of transverse and vertical keels in curtain walls in the market mainly comprises two modes of splicing and welding. Wherein, the splicing is divided into two types: one is a sub-unit sequential installation mode, namely, a first vertical keel is installed firstly, and then transverse keels and vertical keels are installed on the side face of the first vertical keel in sequence alternately until the installation of the whole curtain wall is completed; the other is a mode of transverse keel post-mounting, namely, all vertical keels of the curtain wall are mounted according to a set interval size, and then the transverse keels between the adjacent vertical keels are mounted. The former installation method has the disadvantage that once an error occurs after the installation of the curtain wall or other factors require replacement of the keels, all keels after the replacement position need to be detached, otherwise the keels cannot be taken out, and accumulated errors are easy to occur when the sub units are installed in sequence, so that larger deviation is easy to occur in the separation dimension between the last installed vertical keels, for example, 50 separation is easy to occur from left to right installed curtain walls, if the length of each transverse keel is reduced by 3mm, each separation dimension (the distance between adjacent vertical keels) is also reduced by 3mm, and the final error accumulation can reach 150mm. The later installation mode is to install the transverse keels among the vertical keels after all the vertical keels are installed, and only the keels which need to be replaced are needed to be correspondingly disassembled and assembled when any keels are replaced, and the installation mode can not have accumulated errors.
However, the existing curtain wall technology of the transverse keel post-mounting is not mature enough, and has the following defects:
1. the connecting pieces and the screws between the keels are difficult to conceal, and most of the connecting pieces and the screws are exposed outside, so that the installation of the curtain wall plate is affected, and the appearance of the curtain wall after the curtain wall is installed is not concise and exquisite enough;
2. the required connecting piece of connection and screw quantity are many between the fossil fragments, lead to the dismouting degree of difficulty big, inefficiency to still need set up a large amount of fastening mounting holes on the fossil fragments, can cause the influence to the intensity of fossil fragments, also can reduce the rust-resistant performance of fossil fragments.
3. The force transmission is carried out through the direct fastening of screw between fossil fragments and the connecting piece, has that joint strength is difficult to guarantee, easy not hard up inefficacy and security low scheduling problem, and the screw is connected on the lateral wall of fossil fragments, and stress balance nature and stability are poor, and the lateral wall of tubular fossil fragments also warp and damage easily, and this is just high to the wall thickness requirement of fossil fragments, has increased fossil fragments weight and overall cost.
