Construction and measurement method to ensure levelness of cast-in-place structure roof

Abstract

The invention discloses a construction and measurement method for ensuring the levelness of the roof of a cast-in-place structure. According to the structural design drawings and the positions of the shear walls and beams, the method selects the camber values ​​of different material templates and strictly controls the error; Check the flatness of the formwork system before pouring, and check the flatness of the formwork system again before the concrete is initially set during the pouring process. If there is an error, correct it in time to ensure that the flatness of the formwork system meets the flatness of the cast-in-place structure roof The flatness requirements of the cast-in-place structure roof shall be measured after the formwork is removed to ensure the flatness requirements of the cast-in-place structure roof. The method overcomes the defects of the traditional cast-in-place structural roof construction, ensures that the flatness of the support system meets the flatness requirements of the structural roof, improves the qualified rate of the flatness of the structural roof, saves construction costs, and improves construction efficiency and quality.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a construction and measurement method for ensuring the levelness of a cast-in-place structure roof. Background technique [0002] The roof of the cast-in-place structure is the roof that is manufactured after setting up formwork, tying steel bars, pouring concrete, curing, and removing the formwork at the site according to the design position. The roof of the cast-in-place structure forms an integral structure with the building, which has the characteristics of good earthquake resistance, firmness, durability, good fire resistance, low cost, and a longer service life. The construction quality of the roof of the cast-in-place structure plays a vital role in the quality of the house delivered in the later period. For example, because the roof is too large, the putty on the roof will be scraped unevenly or the headroom size will be affected if it is too thick. Due to the f...

The construction quality of the roof of the cast-in-place structure plays a vital role in the quality of the house delivered in the later period. For example, because the roof is too large, the putty on the roof will be scraped unevenly or the headroom size will be affected if it is too thick. Due to the formwork and construction The pass rate of the flatness of the cast-in-place structural roof is low, and a large number of repair and painting operations are often required in the later stage, which seriously affects the construction efficiency and construction cost
