Storied building top surface crack preventing method

Abstract

The invention relates to a construction method for preventing cracks on the top surface of a building. During the process from the construction of the top surface of the building to the pouring of concrete, lay the bamboo reinforcement mesh in the concrete twice, so that the two layers of bamboo reinforcement mesh are finally sealed in the concrete, and the upper layer of bamboo reinforcement mesh is 3-5mm away from the upper surface of the concrete. The distance between the upper and lower layers of bamboo reinforcement mesh is 8-10mm, the cross-sectional area of ​​a single bamboo wire constituting the upper layer of bamboo reinforcement mesh is 2-3mm2, and the holes of the upper layer of bamboo reinforcement mesh are squares with a side length of 10mm, forming the lower layer of bamboo reinforcement mesh The cross-sectional area of ​​bamboo strips is 15-20mm2, and the holes are squares with a side length of 3cm. The periphery and corners of the roof of the building are still treated according to conventional waterproof measures.

Description

(1) Technical field [0001] The invention relates to a construction method for preventing cracks on the top surface of a building. (2) Background technology [0002] Due to the temperature difference between winter and summer and day and night, the top surface of the building is prone to cracks under the action of repeated thermal expansion and contraction, resulting in leakage of roof rainwater. Since some small cracks are difficult to find with the naked eye, repair It is both very troublesome and the effect is not good. Adopting full waterproof measures on the roof of the building can solve this problem better, but the investment and construction costs are very high. (3) Contents of the invention [0003] The purpose of the present invention is to provide a construction method for preventing cracks on the roof of a building, so as to prevent water leakage from the cracks on the roof of the building, and at the same time greatly reduce the investment in the waterproofing...
