Description
(the application is a divisional application of a keel connecting structure of a curtain wall, the application date of the original application is 28.04.2017, the application number is 201710294886.9, and the invention is named as the keel connecting structure of the curtain wall.)
Technical Field
The invention relates to the technical field of constructional engineering, in particular to a keel connecting structure of a curtain wall.
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 150mm. And then a mounting means is because with the horizontal keel between the complete back of installing vertical keel is installed again, only need corresponding dismouting need change when changing wherein any fossil fragments can to cumulative error can not appear in this kind of mounting means.
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;
