Problems solved by technology

The disadvantage of this construction method is that such buildings usually have large spans and high heights, and the workload of scaffolding is very large, and the relevant regulations require that the height of ordinary fastener-type steel pipe scaffolding should not exceed 40 meters, and those exceeding 40 meters Other steel support frames should be used as the operating platform to ensure the safety of construction, resulting in high construction costs and low construction efficiency; therefore, it is necessary to improve

Embodiment 1

[0044] refer to Figure 1 to Figure 8 , a steel structure string truss system roof suspended ceiling structure, comprising a string truss system, a roof 2 and a ceiling frame.

[0045] specific reference figure 1 and figure 2 , the string truss system includes several string trusses 1 and purlins 16, the string truss 1 is composed of upper string beams, lower string cables 12, steel columns 13, struts 14 and diagonal stay rods 15 connected to form, The upper string beam is a double-box structure formed by connecting two arc-shaped steel beams 11. The two ends of the upper string beam are respectively supported by two steel columns 13, and the two lower string cables 12 are respectively connected to the two curved steel beams of the upper string beam. At both ends of the steel beam 11, there are struts 14 and oblique rods 15 between the lower string cables 12 and the curved steel beams 11 to connect the upper string beams and the lower string cables 12 in tension; several pu...

Embodiment 2

[0056] refer to Figure 9 to Figure 12 , the construction method of the steel structure string truss system roof suspended ceiling structure of embodiment 1, specifically set up the ceiling frame on the string truss system, it comprises the following steps:

[0057] Step 1, refer to Figure 9 , the two arc-shaped steel beams 11 of the upper chord beam in the string truss system are marked with the installation positions of the suspender connectors, and the installation positions of the suspender connectors are located within 0.5 meters of the upper nodes of the struts; The work platform is used as a personnel operation platform, and the davit connector and davit 4 are installed sequentially on the upper chord of the tension truss system, and several electric hoists are installed on the upper chord of the tension truss system corresponding to the installation position of the ceiling truss unit 3.

[0058] Step 2, refer to Figure 9 , according to the installation position of ...

Abstract

The invention provides a steel-structure string truss system roof ceiling structure. The steel-structure string truss system roof ceiling structure comprises a string truss system, a roof and a ceiling frame. Particularly, the ceiling frame is mounted on the lower portions of upper string beams of the string truss system through a plurality of hanging columns; the top ends of the multiple hanging columns are vertically connected to the two sides of the upper string beams of the string truss system through hanging column connecting pieces; ceiling connecting pieces are arranged at the lower ends of the hanging columns; the ceiling frame comprises a plurality of ceiling truss units; and the edges of the ceiling truss units are connected with the ceiling connecting pieces of the hanging columns. The roof ceiling structure has the characteristics of being simple in structure, firm and easy to construct. The invention further provides a construction method of the roof ceiling structure. The construction method comprises the steps that 1 the hanging column connecting pieces, the hanging columns and electric hoists are mounted; 2 the ceiling truss units are lifted up; 3 a fan, a ventilation pipe and a fire water monitor are laid; 4 a ceiling is laid; 5 the ceiling truss units are hoisted; 6 the ceiling truss units and the hanging columns are connected; and 7 the steps from 2 to 6 are repeated. The construction method has the characteristics of convenient, rapid and safe construction.

Description

technical field [0001] The invention relates to the field of building construction, in particular to the structure and construction method of a suspended ceiling in a steel structure tension truss system building. Background technique [0002] The applicant earlier applied for a long-span double-box girder double-cable tension truss system, the application number is 201520282803.0, which includes a number of tension trusses, and the tension truss is composed of lower string cables and upper string girder connections The upper string beam is composed of two arc-shaped steel beams connected by steel beam connectors. The two ends of the upper string beam are respectively supported by two steel columns. The chord trusses are sequentially connected at intervals. The construction method of the suspended ceiling in this kind of building is usually: set up scaffolding in the building, send the suspended ceiling piece by piece to the bottom of the upper string beam through the lifti...
