Problems solved by technology

Advantages and disadvantages, the support speed is fast, the cost is high, the appearance is good, it can achieve the effect of dry wall, and it cannot be used repeatedly
[0008] Looking at the above four construction methods, for the construction of three-dimensional curved reinforced concrete structure walls, either the construction cost is low but the construction difficulty is high and the construction effect is poor, or the construction effect is good but the cost is high and cannot be repeated. use, waste

Embodiment 1

[0047] Taking the wall as a three-dimensional curved wall as an example, the elevation is +0.5~+5.5; +5.5~+9.7, to the parapet wall, there are wall 1, wall 2, wall 3, wall 4, wall 5, wall 9, and the wall thickness is 300-400mm, three-dimensional curved walls with different heights and different radii. This is a major feature of the project's artistic requirements, and it is also the biggest difficulty of the concrete formwork.

[0048] In view of the above characteristics, it was decided to use the technology of "wall reinforced plywood large formwork" for combined design, equipped with related components and support control system, to solve the changes of different curvatures in three-dimensional space, to ensure simple dismantling of formwork, high work efficiency, and can be used in different The height of the floor can be casted to meet the requirements of the clear water surface wall. There are 12 three-dimensional walls in this project, and the formwork makes a total of...

Abstract

A method for constructing 3D curved reinforced concrete wall by splicing the large formworks to obtain a greater hyperbolic formwork is disclosed. Its advantages are high shaping effect, high construction speed, and low cost.

Description

technical field [0001] The invention belongs to a processing method for a concrete wall with a special shape, and in particular relates to a three-dimensional curved reinforced concrete structure template and a construction method. Background technique [0002] Hyperbolic wall, the shape of the wall is a surface formed by drawing an arc with the space radius and running around the horizontal radius. The wall is a cast-in-place concrete wall; the construction quality of the wall meets the requirements of fair-faced concrete, that is, no decoration is required for one-time molding The surface of the standard concrete should be flat and smooth, the color uniform, the construction joints should be arranged regularly, and the flatness, verticality, and cross-sectional size of the concrete should meet the requirements of the specification, and there should be no honeycomb pockmarks. Please refer to Figure 1 for the specific shape. [0003] There are currently several methods for ...
