Description

Curtain wall keel connecting structure based on internal expanding groove

The application is a divisional application of a curtain wall keel connecting structure based on an internal expansion groove, the application date of the original application is 28/04 in 2017, and the application number is 201710296162.8.

Technical Field

The invention relates to the technical field of constructional engineering, in particular to a curtain wall keel connecting structure based on an internal expanding groove.

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 the disadvantage that once an error occurs after the installation of the curtain wall or 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 during the sequential installation of the sub-units, which causes the separation size between the finally installed vertical keels to easily generate large deviation, 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 partition size (the distance between the adjacent vertical keels) is also reduced by 3mm, and the final error accumulation can reach 150 mm. 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. Carry out the transmission of power through the direct fastening of screw between fossil fragments and the connecting piece, have that joint strength is difficult to be guaranteed, easily become 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, the lateral wall of tubular fossil fragments also is easy to warp and damaged, and this is high with regard to the wall thickness requirement of fossil fragments, has increased fossil fragments weight and overall cost.
