Problems solved by technology

Using this method to construct the curved surface must manufacture the back frame (keel) with different curvatures in sections, so not only the construction operation is complicated and difficult, but also the keel material is difficult to reuse after completion

Embodiment 1

[0028] The saddle-shaped hyperboloid concrete slab construction method of the present embodiment is carried out as follows:

[0029] The first step is to measure and set off the line - because the saddle-shaped hyperboloid is a part of the hyperboloid, and the hyperboloid has the geometric characteristics that any point on it can extend out of two intersecting straight lines on the hyperboloid, so it can be drawn with the help of a computer and other drawing tools (This embodiment uses solidworks three-dimensional software) to form the three-dimensional geometric model of the saddle-shaped hyperboloid concrete slab to be constructed, and establish a space grid composed of intersecting spatial straight lines on it according to a predetermined accuracy, and then the space grid is vertically The projection to the plane is a plane grid formed by intersecting plane lines, and the spatial intersection points in the space grid correspond to the projection intersection points in the pl...

Abstract

The invention relates to a saddle-shaped hyperboloidal concrete slab construction method, and belongs to the technical field of building construction. The method includes the steps of surveying and lining, upright rod erecting, support system construction, fillet mounting, formwork set up, reinforcement assembling, cover plate building, concrete pouring and the like. The method ingenuously utilizes the hyperboloid geometric characteristic that any point on a hyperboloid can extend to form two intersection straight lines positioned on the hyperboloid, and building materials of all supports and formwork supports are kept straight. Therefore, compared with the prior art, the method has the advantages that common traditional building materials such as steel pipes, reinforcements and wood boards are needed only, complex curves need not to be drawn, manufacturing of bent members is completely unnecessary, construction is quite convenient, requirements on skills of operators are low, good concrete structure forming impression is guaranteed easily, and detached building materials can be recycled after completion.

Description

technical field [0001] The invention relates to a construction method, in particular to a construction method for a saddle-shaped hyperboloid concrete slab, and belongs to the technical field of building construction. Background technique [0002] It can be seen from space geometry that a hyperbola can be formed by rotating around an ellipse. For example, the ellipse equation at the zero point of the z-axis is: [0003] x 2 a 2 + y 2 b 2 = 1 [0004] The hyperbolic equation at the zero point of the y-axis is: [0005] x 2 a 2 - z 2 c 2 = ...
