Construction method of special-shaped curved surface concrete roof

Abstract

The invention relates to a construction method of a special-shaped curved surface concrete roof, which comprises the following steps of: dividing arc-shaped sections of the roof, namely dividing the sections of the roof into a plurality of arc-shaped surfaces in the transverse and longitudinal directions on the arc-shaped roof according to a design drawing; performing computer pre-arranging, positioning the whole arc-shaped surface according to the divided arc-shaped surfaces and the four points of each arc-shaped surface, and modeling the arc-shaped roof; positioning and paying off: positioning the arc-shaped roof by adopting a three-dimensional horizontal projection method; positioning and erecting the support frames, namely positioning the support frames on the lower-layer structure surface in a longitudinal and transverse arrangement line manner according to the positioning result of the computer, and marking the positioning coordinates and height of each support point on the lower-layer structure surface; mounting a template and reinforcing steel bars; pouring concrete; maintaining; and removing the template. The construction method of the special-shaped curved surface concrete roof has the effect of improving the quality of the special-shaped curved surface concrete roof.

Description

Technical field [0001] The application relates to the field of construction methods of concrete roofs, in particular to a construction method of special-shaped curved concrete roofs. technical background [0002] At present, most roofs are mainly flat roofs, but with people's demand for diversified choices of architectural shapes, more and more special-shaped curved roofs with various curves are accepted and loved by the public. [0003] In view of the above-mentioned related technologies, it is difficult to construct special-shaped curved surfaces in the process of construction because of their respective arcs in both vertical and horizontal directions. Conventional construction methods applied to flat roofs are easy to cause quality problems such as concrete collapse, holes and cracks. Inventive content [0004] In order to improve the quality of special-shaped curved concrete roof, this application provides a construction method of special-shaped curved concrete roof. [0005...

AI Technical Summary

Problems solved by technology

[0003] In view of the above-mentioned related technologies, the special-shaped curved surface forms arcs in both vertical and horizontal directions, so it is difficult to construct during the construction process. Conventional construction methods applied to flat roofs are likely to cause quality problems such as concrete slump, holes and cracks.
