Embodiment 1

[0049] Embodiment 1: TRC inner wall grid type permanent formwork manufacturing method, comprising the following steps:

[0050] Step 1, fiber woven mesh surface dipping and sandblasting;

[0051] Step 2. Install the internal mold required for the grid-type inner wall of the TRC permanent formwork;

[0052] Step 3, outer mold installation;

[0053] Step 4, placing the fiber woven net;

[0054] Step 5, pouring high-performance fine concrete and curing;

[0055] Step 6, demoulding.

[0056] The steps of step 1, surface dipping and sandblasting of the fiber woven mesh are as follows:

[0057] (1) The implementation method of impregnating the fiber woven mesh; first weave the fiber woven mesh, and then fix it to the PVC plastic sheet according to the required template shape to form the required fiber woven mesh shape; then brush the configured epoxy The resin coating solution is evenly applied on the fiber woven mesh, and the whole process should be careful not to cause knots ...

Abstract

The invention relates to a manufacturing method for a TRC inner wall grating type permanent formwork, and belongs to manufacturing methods for reinforced concrete construction formworks. The manufacturing method for the TRC inner wall grating type permanent formwork comprises the following steps that (1) the fibrage net surface is subject to gum dipping and sand blasting; (2) an inner formwork needed by the TRC permanent formwork grating type inner wall is installed; (3) an outer formwork is installed; (4) a fibrage net is installed; (5) pouring of high-performance fine concrete and maintenance are carried out; and (6) demolding is carried out. After the above steps are completed, the surface of the inner wall of the formwork has a grating type characteristic, and the TRC inner wall grating type permanent formwork is formed. By means of the formwork, the superficial area of the joint of cast-in-place concrete and the formwork is increased, the adhesive property of the two parts after pouring can be guaranteed, the interface position is not prone to generating shearing peeling damage, the weight of a traditional permanent formwork can be reduced, and the light and high strength effects are achieved in the construction process.

Description

technical field [0001] The invention relates to a method for manufacturing a reinforced concrete construction template, in particular to a method for manufacturing a TRC inner wall grid type permanent template. Background technique [0002] Nowadays, formwork engineering has been developed for a long time in the reinforced concrete engineering widely used all over the world, and the materials used have gradually developed from the initial single material to the direction of new composite materials. Formwork engineering is one of the necessary The indispensable link plays a vital role in the construction process. In cast-in-place concrete structure engineering, the amount of formwork used per cubic meter of concrete engineering is as high as 4m 2 ~5m 2 , Formwork engineering generally accounts for 30% to 35% of the total construction cost, 40% to 50% of the total labor, and half of the construction period. It can be seen that the formwork project affects the construction p...
