Embodiment Construction

[0039] The present invention is further described in conjunction with the following examples.

[0040] The roof measurement and control construction method created by the invention needs to quickly and accurately measure the axis elevation of the curved surface of the curved concrete roof before building the construction bottom formwork. The invention uses the coordinate grid measurement and positioning method to project the spatial curved surface horizontally. The axis elevation measurement specifically includes the following steps:

[0041] A. Curved concrete roof such as figure 1As shown, by using the finite element analysis software, it is projected in three directions, namely projecting the curved concrete roof to the horizontal plane along the vertical direction, projecting the curved concrete roof to the rear and projecting the curved concrete roof to the left side projection.

[0042] B. The curved concrete roof is projected on the horizontal plane to form the first ...

Abstract

The invention relates to the technical field of building construction, in particular to a measurement, control and construction method for a curved roof formwork system. Projection division is carried out on a curved surface of a concrete roof in measurement location, and the space elevation of any point on the curved surface can be accurately calculated through the coordinate plane conversion calculation formula. With the axis as the basis, the horizontal projection of the curved surface is divided into a plurality of small-specification grids, then the elevation of the grid nodes of the grids is calculated for carrying out measurement and location, and finally the grids are connected to form a smooth spatial curved surface for serving as the basis of setting up the curved roof formwork system. According to the elevation, back purlins are cut in a lofting mode, common formworks and bamboo clamp plates are used cooperatively for forming a bottom formwork of the curved roof formwork system, steel pipe cross rods are set up to support the bottom formwork, and bent steel bars are laid on the bottom formwork which is set up. According to the invention, the measurement difficulty and the construction labor intensity are lowered, the construction progress is accelerated and the construction quality is improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a measurement and control construction method for a curved roof formwork system. Background technique [0002] The pre-construction preparation of the curved concrete roof requires the elevation of the curved roof, and then the elevations are connected to form a curved surface as the basis of the curved roof formwork system. In related technologies, the elevation of curved concrete roofs is generally measured directly with equal cross-sections. Since curved concrete roofs are three-dimensional curved surfaces in space, it is difficult to measure directly and the operation is cumbersome. Inaccurate positioning will occur, resulting in inaccurate final curved roof formwork system, thus affecting the construction quality of curved concrete roofs. Contents of the invention [0003] The purpose of the present invention is to avoid the above-mentioned deficiencies in t...
