The invention discloses a cable tensioning method for a large-span cable glass curtain wall, comprising: establishing a mechanical analysis model of the curtain wall, designing the cables to be stretched to be symmetrically arranged on both sides of the curtain wall along the length direction of the curtain wall, Apply a test load to the model to obtain the force analysis results of each cable under the test load; measure and set out the line at the construction site to determine the positioning points of the top support and the bottom support for installing the cables, and place the top support It is designed in one-to-one correspondence with the bottom support; according to the positioning point, install the top support on the top beam of the curtain wall symmetrically along the length direction of the curtain wall and install the bottom plate support on the curtain wall foundation symmetrically arranged on both sides of the curtain wall; at the corresponding A cable is installed between the top support and the bottom support; according to the force analysis results, the cable is tensioned. The invention provides a basis for the construction process control through the force analysis of the model, so as to meet the basic design principles of the project and ensure the safety of the structure during the stretching process.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a cable tensioning method for a large-span cable-cable glass curtain wall. Background technique [0002] At present, newly-built large-scale public and civil buildings, especially large-space and long-span buildings, must carry out cable tensioning construction of large-span cable-stayed glass curtain walls. However, due to the large span of the curtain wall and the large number of cables, the conventional curtain wall cable tensioning method is not suitable for the cable tensioning construction of the large-span cable-stayed glass curtain wall. Therefore, it is necessary to develop a new cable tensioning construction suitable for large-span cable-stayed glass curtain walls. Contents of the invention [0003] In view of the above problems, the present invention provides a cable tensioning method for a large-span cable-stayed glass curtain wall, comprising: [00...
