Problems solved by technology
Tie rods usually have a length of about 1 to 2m, and the entire roof system is equipped with a large number of tie rods. Due to the thin wall of the purlins and many connection points with the roof beams, and the thinner diameter of the tie rods (usually about 12mm in diameter), it is difficult to carry out installation after ground assembly. The installation method of piece hoisting
The conventional engineering method is to install the tie rods one by one. Since the installation of the tie rods is a high-altitude operation, the hoisting and installation of the tie rods in place and installation at each connection point must be repeated once more, and the safety rope needs to be untied and reinstalled every time it is moved. Setting, resulting in relatively low construction efficiency, the construction period will be extended, and the construction cost will increase

Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings.
[0023] In the figure, the method for installing a plurality of evenly distributed thin tie rods on a large-span roof of the present invention includes the following construction steps:
[0024] Step one as figure 1 , 2 As shown, roof purlin inspection; according to the design requirements, check the installation process and quality of roof beam 1 and roof purlin 2;
[0025] Step two as image 3 , 4 As shown in the figure, set up the rod roof transportation device; the longitudinal distance between the roof purlins 2 is 1~2m, and the weight of a single rod 6 is about 1~2kg. In the longitudinal direction of the four roof purlins 2 on the roof and perpendicular to the longitudinal centerline of the roof purlins 2, the groove of the cable bridge is upward and the openings at both ends are welded and sealed with steel plates to form a roof transportation device 3 with a...

The invention discloses an installation method of multiple uniform-distributed thin praline pull rods on a large-span roof. The installation method comprises the construction steps of: (1) roof praline checking; (2) arrangement of a pull rod roof transportation device; (3) arrangement of a safety belt; and (4) transportation and installation of the pull rods. The installation method has the advantages of realizing quick installation of the pull rods, improving the construction efficiency, enhancing the working efficiency of transporting and installing the pull rods and reducing the construction cost.
Description
technical field [0001] The invention relates to a building construction method, in particular to a method for installing a plurality of uniformly distributed purlin thin tie rods on a large-span roof. Background technique [0002] At present, in order to increase the support strength of the roof purlins in the construction of steel structure roofs, two to four tie rods are arranged vertically and equidistantly between every two purlins. Fix with nuts, and form two or two purlins into a whole. Tie rods usually have a length of about 1 to 2m, and the entire roof system is equipped with a large number of tie rods. Due to the thin wall of the purlins and many connection points with the roof beams, and the thinner diameter of the tie rods (usually about 12mm in diameter), it is difficult to carry out installation after ground assembly. The installation method of slice hoisting. The conventional engineering method is to install the tie rods one by one. Since the installation of ...
