Description
Technical Field
The invention relates to the technical field of constructional engineering, in particular to an internal connection type curtain wall keel duplex connection structure.
Background
At present, the connection of horizontal keel and vertical keel in the curtain wall in the market is mainly splicing and welding. Wherein, the concatenation is divided into two kinds again: one is a sub-unit sequential installation mode, namely, a first vertical keel is installed at first, and then a transverse keel and a vertical keel are alternately installed on the side surface of the first vertical keel in sequence until the installation of the whole curtain wall is completed; the other mode is a transverse keel after-loading mode, namely all the vertical keels of the curtain wall are installed according to the set interval size, and then the transverse keels between the adjacent vertical keels are installed. The former mounting method has a disadvantage that once an error occurs after the installation of the curtain wall or once other factors need to replace the keel, all the keels after the replacement position need to be disassembled, otherwise the keels cannot be taken out, and accumulated errors easily occur in the sequential installation of the units, which causes a large deviation of the separation size between the vertical keels installed at last, for example, 50 partitions exist in the curtain wall installed from left to right, if the length of each transverse keel is reduced by 3mm, each separation size (the distance between adjacent vertical keels) is also reduced by 3mm, and the final error accumulation can reach 150mm. The horizontal keel between the vertical keels is installed again after the whole installation of the vertical keels is completed in the latter installation mode, the keels needing to be replaced only by corresponding dismounting during replacement of any keel are needed, and accumulated errors cannot occur in the installation mode.
However, the existing curtain wall technology after installing the cross keel is not mature enough, and has the following defects:
1. connecting pieces and screws between the keels are difficult to hide, most of the connecting pieces and the screws are exposed outside, so that the installation of the curtain wall plate is influenced, and the appearance of the curtain wall after installation is not concise and exquisite;
2. the required connecting piece of connection and screw between the fossil fragments are in large quantity, 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 transmission of power is carried out through the direct fastening of screw between fossil fragments and the connecting piece, has the difficult assurance of joint strength, easily becomes flexible inefficacy and security low scheduling problem, and the screw all is connected on the lateral wall of fossil fragments, and force balance nature and poor stability, and the lateral wall of tubular fossil fragments also is easy to be out of shape and damaged, and this just requires highly to the wall thickness of fossil fragments, has increased fossil fragments weight and overall cost.
