Arc-shaped sloping roof contour plate construction structure and construction method thereof

Abstract

The invention discloses an arc-shaped sloping roof contour plate construction structure and a construction method thereof, and belongs to the technical field of building construction. The arc-shaped sloping roof contour plate construction structure comprises an H-shaped steel beam, a contour plate assembly, a short L-shaped folded plate and a long L-shaped folded plate, the contour plate assemblyis arranged on the upper portion of the H-shaped steel beam, and the H-shaped steel beam and the contour plate assembly are connected through the short L-shaped folded plate and the long L-shaped folded plate; and the contour plate assembly comprises an obliquely-arranged contour steel plate, a plurality of sets of longitudinal truss ribs, a plurality of longitudinal bottom ribs and a bidirectional reinforcing mesh arranged on the upper portions of the longitudinal truss ribs. According to the arc-shaped sloping roof contour plate construction structure, the contour steel plate is tightly andfirmly fixed to the H-shaped steel beam in a slope environment, so that the construction safety is ensured; after a roof cast-in-place slab is poured, the contour steel plate and a concrete structureare stressed to work together, and the consumption of concrete between the steel beam can be reduced; and finally, the purposes of using the concrete as a cast-in-place slab bottom mold in the slope environment, shortening the construction period, reducing the construction cost and increasing the benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a construction structure and a construction method of a profiled plate for an arc-shaped sloping roof. Background technique [0002] In buildings with steel structures as the main body, profiled steel plates are often used as a non-dismantling bottom formwork for cast-in-place slabs on flat floors. Profiled steel plates are usually placed on horizontal floor steel beams for use, and there is no special requirement for the production and fixing of profiled steel plates. Requirements; the main environmental feature of this process is that it is used on a horizontal floor plane, and this process is not suitable for arc-shaped sloping roof structures. [0003] When the profiled steel plate is used on the arc-shaped sloping roof structure with steel structure as the main body, the following technical difficulties need to be solved: [0004] One is the fixing...

AI Technical Summary

Problems solved by technology

[0004] One is the fixing of the upper and lower ends of the profiled steel plate on the H-shaped steel beam: on the slope, when the upper and lower ends of the profiled steel plate intersect with the inclined plane of the H-shaped steel beam and the level, the profiled steel plate cannot be fixed tightly to the steel plate at the top of the steel beam , resulting in problems such as loose fixation, concrete grout leakage, and changes in the stress of steel beams

[0005] Second, it is not possible to increase the thickness of the concrete roof slab due to the use of inclined profiled steel plates, which will greatly increase the load on the steel beams and affect the use of the structure: if the profiled steel plates are fixed on the flange or axis of the H-shaped steel beams, the distance between the steel beams will be additionally increased. The thickness of the inter-cast-in-place slab increases the load; if the continuous profiled steel plate is used on the multi-span steel girder, the stress point of the steel girder is transferred to the edge of the steel girder flange plate, which changes the force design of the steel girder axis. original intention

[0006] If the above situation is not resolved and the ordinary wooden formwork support technology is adopted, the construction period will be greatly extended and various costs will be greatly increased
