Problems solved by technology

[0003] Aiming at the problem in the above-mentioned prior art that there are no pillars and large construction projects with a span of more than 100 meters cannot use rigid bar combinations as a fully enclosed supporting platform for the roof, the present invention proposes a platform that can be used without pillars and with a span of 100 meters. A support platform for large mid-span buildings over 100 meters to achieve roof support and fully enclosed construction, ensure project quality, reduce project cost, and improve project earthquake resistance

Embodiment Construction

[0026] One, in figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 In the construction project, a truss 1 is set around the construction project. The truss is formed of steel materials or reinforced concrete columns with sufficient strength and rigidity. The span of the truss is 270 meters in the X direction and 207 meters in the Y direction, which is 270 meters × 207. There are no pillars within meters. Lightweight beam 3 adopts I63C# aluminum alloy I-beam. Of course, light beams made of other light alloys can also be used. The distance between the light beams in the X and Y directions is 9 meters. There are 30 pitches and 23 pitches in the Y direction, that is, there are 30 light beams in the X direction and 23 light beams in the Y direction. The aluminum alloy I-beams are staggered and fixedly connected to form a framework of 270 meters × 207 meters. The strength and rigidity of the truss should be designed and constructed to ensure that it can with...

Abstract

The invention discloses a supporting platform for sealing large-span building roofs, which comprises a framework body and a steel cable net, wherein the framework body is formed by light beams (3) which are fixed and connected alternately and at intervals; the periphery of the framework body is supported and fixed on a girder (1); the steel cable net is formed by steel cables which pass through the light beams and are spaced, interlaced and extended; and clamping devices for integrating the steel cable net and the framework body are arranged on two sides of the steel cables passing through the light beams. With a flexible structure, the supporting platform has low mutual dependency and high strength and rigidity and can improve the earthquake resistance and safety coefficient of large-span building projects. The supporting platform is convenient to construct. The construction cost of the supporting platform is as low as less than 5,000 Yuan per square meter, which is much lower than the construction cost (40,000 Yuan / m<2>) of the conventional building project supporting platform with a span of 100 meters. The invention is mainly characterized by providing the supporting platform for supporting roof load and for use in roof construction in the sealing of large-span building project roofs and by solving the problem that the roofs of prop-free building projects with a large span of more than 100 meters cannot be sealed fully is solved.

Description

Technical field [0001] The present invention relates to building components, in particular to a supporting platform used for roof closure of large-span buildings. Background technique [0002] At present, in construction projects, for small and medium-sized construction projects without pillars and spans within 100 meters, most of the small and medium-sized construction projects adopt steel structure, grid structure, suspension structure or thin shell structure, etc., with rigid material rod combination as a fully enclosed roof. Supporting platform, and for large construction projects with no pillars and spans of more than 100 meters (such as stadiums, cultural and entertainment centers, ports, large aircraft manufacturing and parking areas, etc.), the spans of the above large construction projects are generally 100 meters Above, for this kind of large-span construction project, the roof must have a supporting platform when it is closed, otherwise it will be difficult to realize ...
