A method of using degradable plastic film to prevent leakage of slurry

Abstract

A method for preventing slurry leakage by using a degradable plastic film, comprising the following steps: 1. coating a template (1) with a proper amount of edible oil, and flatly spreading a plastic film on one side of the template (1) so that each side of the plastic film is wider a part than the template (1); 2. winding the excessive plastic around the template (1) by using cross bars (4) and bonding to the contact surface of the template (1) by using an adhesive; 3. placing the template (1), and horizontally and vertically fixing the template (1) by using horizontal fixing rods (2) and vertical fixing rods (3), the bottom and top ends of the vertical fixing rods (3) being respectively fixed to the cross bars (4) at the bottom and top of the template (1); 4. pouring concrete into the space defined by the template (1); 5. after the concrete of a wall surface is solidified, removing the horizontal fixing rods and the vertical fixing rods on the outer surface of the template (1) to disassemble the template (1); 6. and coating the contact surface of the cross bars (4) and the template (1) and the contact surface of the plastic and the template (1) with a proper amount of a viscosity remover, so that the plastic is separated from the template (1). According to the method, slurry leakage during pouring is avoided and labor is saved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a method for preventing slurry leakage by using a degradable plastic film. Background technique [0002] Concrete pouring construction includes wall construction, column construction, etc. The construction process is to build steel bars first, then build formwork, fix the formwork, and then pour concrete. [0003] The reasons for grout leakage in the formwork during the construction process are: the material of the formwork does not meet the requirements; the adjacent formwork is uneven and the splicing is not strict; the vertical and horizontal support is not firm, and it cannot withstand the pressure measurement during concrete pouring, resulting in external expansion and runaway phenomena; The concrete is too thin; the vibration time of the vibrating rod is too long in the local area; the slump of the concrete is relatively large; the ground is uneven...

AI Technical Summary

Problems solved by technology

[0005] It can be seen that the damage of grout leakage in the building pouring process is very large, and the existing preventive measures waste labor and materials. If the properties of the concrete are changed, the quality of the building wall will be changed.

[0006] In addition, in the concrete construction of construction projects, after the concrete pouring is completed, a large amount of mortar will remain on the formwork, and the mortar is close to the surface of the formwork, which is difficult to clean

Under normal circumstances, construction personnel use a putty knife to clean the mortar on the surface of the formwork, but the formwork after partial cleaning cannot meet the requirements, resulting in a great waste of human resources; for the prepared formwork with a smooth surface, the adhesion between it and the concrete formwork The resultant force will also cause the concrete form to stick to the concrete
