The support structure and construction method used in the sliding construction of arch rib roof truss

Abstract

The invention discloses a supporting structure and a construction method for arch-rib roof truss sliding construction, and relates to the technical field of arch-rib roof truss installation. The supporting structure is characterized in that horizontal pulling rods are arranged on the same horizontal plane in parallel at equal distance, and two ends of each horizontal pulling rod are respectively connected with an arch-rib roof truss; supporting rods are vertically and fixedly arranged on the ground and are symmetrically arranged relative to a longitudinal axis of the arch-rib roof truss, supporting rods in each pair are respectively arranged at two ends of one horizontal pulling rod, the same horizontal position of each supporting rod is provided with a detachable flange section, and the horizontal pulling rod between each pair of supporting rods is located between the detachable flange sections of the pair of supporting rods. The construction method is characterized by comprising the steps of firstly removing one detachable flange section which is located at the front ends of each pair of supporting rods in the sliding direction, sliding the arch-rib roof truss, and installing the removed detachable flange section; then removing the other detachable flange section, and sliding the arch-rib roof truss; repeatedly carrying out the above steps until the horizontal pulling rods pass through all the supporting rods. According to the supporting structure disclosed by the invention, the structure is simple, the supporting structure is prevented from being removed during a construction process, and the construction safety is ensured.

Description

technical field [0001] The invention relates to the technical field of arch-rib roof truss installation, in particular to a support structure and a construction method for sliding construction of arch-rib roof trusses. Background technique [0002] During the construction of arch-rib roof truss, the weight of the entire arch-rib roof truss is borne by the supporting structure. Before the arch-rib roof truss slides, the arch-rib roof truss needs to be separated from the support structure. Bearing, the arch feet at both ends are not fixed during sliding construction, and because of their arched structure, the arch feet at both ends will generate great external tension, which will affect the construction quality and even cause safety accidents. In order to solve the problem of the external tension of the arch-rib roof truss, the traditional sliding construction of the arch-rib roof truss adopts the method of limiting the outside with tooling or slideways. The use of tooling an...

[0002] During the construction of arch rib truss, the weight of the entire arch rib roof truss is borne by the supporting structure. Before the arch rib roof truss slides, the arch rib roof truss needs to be separated from the supporting structure. Bearing, the arch feet at both ends are not fixed during sliding construction, and because of their arched structure, the arch feet at both ends will generate great external tension, which will affect the construction quality and even cause safety accidents

In order to solve the problem of the external tension of the arch-rib roof truss, the traditional sliding construction of the arch-rib roof truss adopts the method of limiting the outside with tooling or slideways. The use of tooling and foundations increases, and the amount of tooling and foundations to be dismantled after construction is completed
