Garage abrasion-proof concrete pavement terrace crack control method

Abstract

The invention relates to a terrace construction method, in particular to method for controlling a crack of a garage abrasion-resistant concrete pavement terrace. The method comprises the following: a step of layout of isolation joints, which is to arrange the ground isolation joints along the axial line of a building without spanning the center line, to arrange an isolation joint at a distance of 200 millimeters from the wall along the direction of the wall, to arrange a closed quadrangular isolation joint on a position of a structural column at a distance of 200 millimeters from four sides of the column, and to cut off the isolation joints when the isolation joints along the axial line encounter dilatation joints of the foot of the wall or the column without the necessity of cutting the isolation joints to the foot of the column or the wall; a step of cutting construction, which is to snap a line on the ground according to the isolation joint layout designed in advance and then to cut the isolation joints along the snapline by a street cutter with a joint cutting depth 50 millimeters; and a step of caulking, which is to use a high-pressure air pump to blow and wash along the joints and wash clean plastering float in the joints after the isolation joints are cut, and then to use flexible sealing materials to compactly and evenly fill up the isolation joints. The method not only improves the construction speed of the whole ground but also achieves the aim of effective control of ground cracks; and even a small number of cracks exist, the cracks are generated in an isolated lattice, thereby large-area repair can not be caused.

Description

Technical field: [0001] The invention relates to a floor construction method, in particular to a method for controlling floor cracks in a wear-resistant concrete surface layer of a garage. Background technique: [0002] At present, the wear-resistant concrete surface is widely used in the garage floor of large public buildings, and the floor surface cracks caused by temperature changes and the shrinkage and deformation of the concrete itself have become one of the common problems of the garage floor. Therefore, in the process of garage floor construction, how to take effective measures to minimize surface cracks has become an important issue in controlling the quality of floor construction. At present, the main measures to control cracks are: strengthening the maintenance of the surface layer after the construction is completed, such as covering straw curtains, regularly sprinkling water and brushing curing fluid; subdivided and segmented construction; setting separation joi...

AI Technical Summary

Problems solved by technology

[0003] ①Large-area floor concrete cannot be continuously constructed, which will affect the construction progress

[0004] ②Generally, separation joints cannot be reserved in places where cracks are likely to occur, such as walls and column roots.

[0005] ③It is difficult to calender at the separation seam, and the straightness is poor, which affects the appearance

[0006] ④ The materials used for separation cannot be turned over, resulting in a certain waste of materials
