preparation example Construction

[0030] The preparation method of the TRC formwork reinforced concrete column of the present invention, the specific steps are as follows:

[0031] a. The fiber woven net with high tensile strength and good corrosion resistance is used, and the fiber woven net is dipped or reinforced with steel wire mesh; the fiber woven net adopts carbon fiber, aramid fiber, and alkali-resistant glass fiber , Basalt fiber, polyvinyl alcohol fiber, or polyethylene fiber weaving, or weaving with two different fibers according to the weaving radial and weft directions. The described dipping process: first impregnate with epoxy resin, and perform sandblasting treatment before impregnating the fiber woven net with epoxy resin before curing, wherein the mass ratio of the epoxy resin, curing agent, and diluent impregnated with the fiber woven net is 65 ~70: 60~80: 30~35, silica sand is generally used for sand;

[0043] Example 1, such as figure 1 As shown,

[0044] 1. Fiber woven net dipped or steel wire net lining fixed fiber woven net

[0045] The fiber woven net is knitted by fiber coarse sand. It is a high-performance soft fabric. The untreated fiber woven net is not easy to be laid on the concrete member independently. It is dipped to harden the fiber woven net, or the steel wire net is used. To fix the untreated fiber woven net. The dipping can make the inner and outer fibers uniformly stressed, and can connect the organic thread and roving used for the stitched fiber woven net to increase the adhesion and mechanical occlusion, and form a protective layer on the surface of the fiber woven net, which is effective Avoid the erosion of the lye in the concrete to the fiber woven net and enhance the durability of the permanent formwork. The specific production method is as follows: first impregnate with epoxy resin, and perform sandblasting treatment before impregnating the fiber woven ...

Abstract

A preparation method for a TRC formwork reinforced concrete column comprises the following steps that a fiber woven mesh with high tensile resist strength and good decay resistance is adopted, and the fiber woven mesh is dipped into glue or strengthened through a steel wire mesh liner; an inner mould is mounted, shear resistant hooks are mounted in drill holes of the inner mould in an inserting mode, and the fiber woven mesh is fixed to the outer side of the inner mould; an outer mould is built on the outer side of the fiber woven mesh, prepared high-performance concrete is slowly poured into space formed by the inner mould, the fiber woven mesh and the outer mould, and manufacturing of a TRC formwork is finished; and after a TRC formwork layer reaches the set strength, formwork disassembling is carried out, the concrete is poured into the TRC formwork, and preparing of the TRC formwork reinforced concrete column is finished. Compared with the prior art, time and labor are saved, the cost is reduced, and the construction efficiency is improved; the bearing capacity and ductility of the reinforced concrete column are improved, and the durability of components in severe environments such as a cold environment and an alkalinity environment is improved; and strengthening of a building is more efficient, simpler, cheaper and more environmentally friendly.

Description

Technical field [0001] The invention relates to a preparation method of a reinforced concrete column, in particular to a preparation method of a new type TRC template reinforced concrete column suitable for the construction of a reinforced concrete structure, and belongs to the technical field of concrete reinforcement. [0002] technical background [0003] The cast-in-place concrete formwork is a necessary construction tool for the construction of reinforced concrete structures with a large amount of use and a wide area. According to relevant statistics, the amount of formwork used in the cast-in-place concrete project per square meter is as high as 4 to 5 square meters, the formwork engineering cost accounts for 30% to 35% of the entire project cost, and the labor cost accounts for 40% to 50% of the total labor cost of the entire project. , The construction period accounts for 50% of the entire project period. It can be seen that the formwork project occupies an extremely impor...
