Problems solved by technology

The production of curved support components not only has high technical requirements for construction operators, it is difficult to guarantee the construction quality, but also the work efficiency is extremely low, which cannot meet the requirements of modern construction progress.
The Chinese patent application No. 201210145845.0 discloses a method for aligning the center of the reinforced concrete hyperboloid cooling tower construction cylinder wall, although a beneficial innovation has been made in the construction of the hyperboloid cylinder, but it does not solve the above problems

Embodiment 1

[0030] The construction method of the concrete hyperboloid thin shell cylinder of the present embodiment is carried out according to the following steps:

[0031] The first step, design the construction line——establish a mesh construction line surrounding and located on the hyperboloid cylinder on the three-dimensional geometric figure of the hyperboloid cylinder to be built, distributed at predetermined intervals, and formed by two sets of spatial straight lines with different inclination directions (see Image 6 ). The basis of this step is that each point on the cylinder wall of the hyperboloid cylinder has a straight line passing through this point and located on the hyperboloid surface. With the help of 3D mechanical drawing software such as solidworks, a simulation 3D model of the hyperboloid cylinder can be established and determined. The direction of the straight line on the cylinder, thus forming the textured construction line as the basis for the construction settin...

Abstract

The invention relates to a concrete double-curved-surface thin shell cylinder construction method, and belongs to the technical field of building construction. The method comprises the steps of pay-off measuring, annular pattern plate manufacturing and positioning, cylinder inner support installing, cylinder inner wall pattern plate installing, cylinder steel rib binding, cylinder outer wall pattern plate installing, cylinder outer support installing, double-curved-surface cylinder hoop ridge installing and concrete pouring. According to the concrete double-curved-surface thin shell cylinder construction method, only common traditional building materials such as steel pipes, reinforcing steel bars and pattern plates are needed, requirements for technologies of operating workers are not high, construction is simple and convenient to conduct, concrete structure forming appearance is good, and therefore the method is practicable.

Description

technical field [0001] The invention relates to a construction method, in particular to a construction method for a concrete hyperboloid thin shell cylinder, belonging to the technical field of building construction. Background technique [0002] In order to meet the needs of modern architectural functions and architectural styles, hyperbolic cylindrical structures have been increasingly widely used. The construction method of the traditional concrete hyperboloid cylinder can be referred to the Chinese patent application No. 94117449.2, which needs to make the pouring formwork supported by the curved support member according to the shape of the hyperboloid. The production of curved support components not only has high technical requirements for construction operators, it is difficult to guarantee the construction quality, but also the work efficiency is extremely low, which cannot meet the requirements of modern construction progress. The Chinese patent application number 2...
