[0002] During the reconstruction of old station buildings, the existing operation line will be open to traffic normally, and the roof truss assembly construction cannot be carried out on the upper part. To solve this problem, the method of overall hoisting and installation of the roof in this area is usually adopted, which can maintain the existing operation. Lines are not disturbed, but the lifting requirements are high, and it is difficult to locate large-span roof trusses

Abstract
The invention relates to a roof steel truss slipping rail and a dismounting and installing method thereof. The rail mainly comprises a rail truss, a steel channel rail, a rail truss inclined strut, a rail truss vertical support, a cross shaped steel column, a structure plate, a rail truss top chord, a rail truss lower chord, a rail truss web member, a longitudinal horizontal support beam, a transverse horizontal support beam, a rail baffle, a steel pipe inclined strut, a steel pipe horizontal support, a column end stiffening plate, a column end prewelding beam, an electric block, an inhaul cable, a roof steel truss lower chord and a rail truss unit. The main dismounting and installing method comprises the following steps of (1) making of the rail truss, (2) installing of the rail truss, (3) vertical support installing of the rail truss, (4) installing of the rail truss inclined strut, (5) installing of the steel pipe inclined strut, (7) installing of the steel channel rail and (8) dismounting of the rail truss. The roof steel truss slipping rail and the dismounting and installing method thereof belong to the field of constructional engineering, and a large roof truss is placed on the rail to slide so as to solve the problem that the large roof truss is difficult to move.
Description
technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a roof steel truss sliding track and a disassembly method for roof steel truss sliding construction. Background technique [0002] During the reconstruction of old station buildings, the existing operation line will be open to traffic normally, and the roof truss assembly construction cannot be carried out on the upper part. To solve this problem, the method of overall hoisting and installation of the roof in this area is usually adopted, which can maintain the existing operation. The line is not disturbed, but the lifting requirements are high, and it is difficult to locate the long-span roof truss. Contents of the invention [0003] In view of the above-mentioned problems existing in the prior art, the object of the present invention is to provide a roof steel truss sliding track and disassembly method for roof steel truss sliding construction. T...
