Z-shaped purlins are usually fixed on the purlin seats left by the roof beams and bolts are used to make the two firmly connected. Color tiles are laid and fixed on the Z-shaped purlins and fixed with rivets or bolts. Usually the distance between the purlins is 1500mm, and the Z-shaped configuration of the entire roof system There are a large number of purlins. Due to the thin wall of the purlins (usually the wall thickness is about 2mm), it is difficult to realize the assembly of the purlins on the ground with the roof beams, and then lift them into place in pieces.
The conventional engineering method is to install the purlins one by one, because the installation of purlins is a high-altitude operation, and the construction personnel need to untie and reset the safety rope every time they are moved, resulting in low construction efficiency, prolonged construction period, and high construction costs.

Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings.
[0024] In the figure, the roof thin-walled Z-shaped purlin installation method of the present invention includes the following construction steps:
[0025] Step 1 Movable security device settings:
[0026] At the ends of the lower ends of the roof beam I1 and the roof beam II2, use a fixed steel wire rope 3 to firmly install a fall arrester I4 and a fall arrester II5;
[0027] Step 2 Roof Beam Installation:
[0028] According to the size of the design drawings, the roof beam I1, roof beam II2 and other roof beams are installed to ensure that the installation accuracy of the purlin support 8 on the roof beam meets the technical requirements of the design document;
[0029] Step 3 Roof transportation and installation of purlins:
[0030] The roof purlins are constructed one by one. Before the transportation and installation of purlin I6 and purlin II7, install anti-fa...

Abstract
The invention discloses a mounting method of a roof thin-wall Z-shaped purline. The method comprises the following construction steps of firstly, arrangement of a movable safety guarantee device, secondly, mounting of a roof beam, and thirdly, roof transportation and mounting of the purline. The method has the advantages that construction safety control and the construction speed of the roof purline similarly of steel structure are improved, the construction period of engineering is saved, and the construction efficiency is improved.
Description
technical field [0001] The invention relates to a building construction installation method, more specifically, relates to a roof thin-walled Z-shaped purlin installation method. Background technique [0002] At present, in the construction of steel structure roofs, it is often encountered that in order to increase the support strength of roof tiles, Z-shaped purlins are arranged vertically and equidistantly between every two roof beams. Z-shaped purlins are usually fixed on the purlin seats left by the roof beams and bolts are used to make the two firmly connected. Color tiles are laid and fixed on the Z-shaped purlins and fixed with rivets or bolts. Usually the distance between the purlins is 1500mm, and the Z-shaped configuration of the entire roof system There are a large number of profiled purlins. Due to the thin wall of the purlins (usually the wall thickness is about 2mm), it is difficult to assemble the purlins with the roof beams on the ground, and then lift them i...
