Construction method of multi-layer steel truss building

Abstract

The invention discloses a construction method of a multi-layer steel truss building. The method comprises the following steps: arranging a plurality of reinforced concrete pedestals on the ground in the area corresponding to the steel truss to be arranged; arranging a support frame for bearing the load of the steel truss on the reinforced concrete pedestals, wherein the support frame extends upwards to the bottom of the bottom steel truss; sequentially mounting the steel trusses from the bottom layer to the top layer on the support frame, and integrally connecting the steel trusses with the main body frames on the two sides of the steel trusses; and constructing the main body frames on the two sides of the steel trusses from bottom to top before or while the steel trusses are arranged. According to the method, the support frame is arranged at the lower part of the steel truss and is capable of supporting the steel trusses to be constructed, so that the middle steel truss of the building can be mounted while the main body frames on the two sides are constructed, thereby increasing the construction speed, reducing the construction period and ensuring smooth delivery of the building.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a multi-layer steel truss building construction method. Background technique [0002] In the construction of buildings with multi-layer long-span steel trusses, the traditional steel truss construction methods include high-altitude bulk method, sliding method, and integral hoisting method, but these construction methods need to be carried out under the premise that the structures on both sides of the truss form an integral frame To meet the load requirements of the truss, there are problems such as long construction period, large required site, uneven force and poor stability of the steel truss, and difficulty in docking the steel truss with the main bodies on both sides.

Problems solved by technology

[0002] In the construction of buildings with multi-layer long-span steel trusses, the traditional steel truss construction methods include high-altitude bulk method, sliding method, and integral hoisting method, but these construction methods need to be carried out under the premise that the structures on both sides of the truss form an integral frame To meet the load requirements of the truss, there are problems such as long construction period, large required site, uneven stress and poor stability of the steel truss, and difficulty in docking the steel truss with the main body on both sides.

[0003] In an actual project, the steel structure of the target building has ten floors, a landscape river crosses the middle of the steel structure, and a suspended steel truss with a width of 45m and a total of 7 floors is designed in the middle of the steel structure; the existing design scheme adopts the sliding method The installation of the steel trusses is to give priority to the construction of the main structures on both sides. After the main structures reach the design strength, the installation of the middle river-crossing trusses will be carried out. This scheme cannot be interspersed with processes, and the construction period is long, which is restricted by external factors. The river-crossing truss must be completed before the flood season, and the current plan cannot achieve the expected goal

[0004] Therefore how to solve problems such as the long construction period of multi-storey steel truss buildings is a technical problem that those skilled in the art need to solve at present
