preparation example Construction

[0029] The preparation method of TRC formwork reinforced concrete column of the present invention, concrete steps are as follows:

[0030] a. adopt high tensile strength and good corrosion resistance fiber braided net, impregnate the fiber braided net or reinforce the fiber braided net with steel mesh lining; described fiber braided net adopts carbon fiber, aramid fiber, alkali-resistant glass fiber , basalt fiber, polyvinyl alcohol fiber, or polyethylene fiber weaving, or weaving with two different fibers according to the radial and weft directions of weaving. The impregnation process: first impregnate with epoxy resin, and perform sandblasting before impregnating the fiber woven mesh with epoxy resin and before curing, wherein the mass ratio of epoxy resin, curing agent and diluent for impregnating the fiber woven mesh is 65 ~70: 60~80: 30~35, the sand is generally made of silica sand;

[0031] b. Install the inner mold, the square column uses thin wood as the mold, and the...

Embodiment 1

[0042] Embodiment 1, as figure 1 as shown,

[0043] 1. The fiber woven mesh is dipped in glue or the steel wire mesh is lined to fix the fiber woven mesh

[0044] The fiber woven mesh is woven from fiber coarse sand seams, which is a high-performance soft fabric. The untreated fiber woven mesh is not easy to be laid vertically in the concrete member independently, and the fiber woven mesh is hardened by dipping, or steel wire mesh is used. To fix untreated fiber woven mesh. Dipping can make the inner and outer layers of fibers bear even force, and can connect the organic thread and roving used for stitching the fiber woven net into one, which can increase the bonding and mechanical interlocking, and form a protective layer on the surface of the fiber woven net, which can effectively Avoid the erosion of lye in the concrete to the fiber woven mesh and enhance the durability of the permanent formwork. The specific production method is as follows: first impregnate with epoxy r...

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 method for preparing a reinforced concrete column, in particular to a method for preparing a novel TRC formwork reinforced concrete column suitable for construction of reinforced concrete structures, and belongs to the technical field of concrete reinforcement. technical background [0002] Cast-in-place concrete formwork is an essential construction tool that is widely used in the construction of reinforced concrete structures. According to relevant statistics, the amount of formwork used in each square meter of cast-in-place concrete project is as high as 4 to 5 square meters, the cost of formwork 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 construction period. It can be seen that the formwork project occupies an extremely important weight and position in the ent...
