Oblique adjustable supporting and reinforcing method for cantilever structure

Abstract

The invention discloses an oblique adjustable supporting and reinforcing method for a cantilever structure. The method comprises the following steps that 1, an adjustable supporting and reinforcing structure is determined; 2, the oblique live load of the adjustable supporting and reinforcing structure is calculated; 3, a stable inclination angle of an adjusting supporting rod is determined; 4, an axial force load bearing interval of the oblique support of the adjusting supporting rod is calculated; 5, the length of the adjusting supporting rod is determined; 6, selecting basic parameters of the adjusting supporting rod and looking up a table to obtain a stability coefficient of an axis compression member of the adjusting supporting rod; 7, stability and compression resistance checking calculation is conducted on the adjusting supporting rod; 8, a vertical shaping plate and a non-vertical shaping plate are welded; and 9, the cantilever structure is obliquely supported and reinforced. According to the oblique adjustable supporting and reinforcing method, by the adoption of a telescopic adjusting rod, the construction distance from a cornice to a frame body can be reduced to the maximum extent, safety risks caused by roof cornice construction are reduced, the strength and rigidity of a formwork at the line position of the cornice are guaranteed, it is guaranteed that concrete internal corners are straight and external corners are square, and concrete appearance quality defects are reduced.

Description

technical field [0001] The invention belongs to the technical field of obliquely adjustable support and reinforcement of a cantilever structure, and in particular relates to a method for reinforcing a cantilever structure with an obliquely adjustable support. Background technique [0002] The traditional method of support and reinforcement of cantilevered structures is spliced ​​by loose formwork. The appearance quality of concrete constructed with loose formwork and cantilevered frames is not straight, and the external corners are not square, and there are quality defects. Bulk formwork is often spliced ​​in place and difficult to control, resulting in damage to the inner and outer corners and poor concrete appearance quality. For this reason, there is an urgent need for a new type of formwork support tool suitable for cantilevered structures, and to meet the requirements of cantilevered structure support, reinforcement stability and compression resistance. The required met...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide an obliquely adjustable support reinforcement method for a cantilevered structure in view of the deficiencies in the above-mentioned prior art, which can solve the problem of internal and external corner damage and poor concrete appearance quality caused by improper splicing of bulk formwork At the same time, in the support of the cantilever frame body, the telescopic adjustment rod is used, which can minimize the construction distance from the cornice to the frame body, reduce the safety risk caused by the construction of the roof cornice, and ensure the correctness of the formwork at the cornice line. Strength and rigidity, to ensure that the concrete inner corners are straight and the outer corners are square, reduce the appearance quality defects of concrete, and facilitate popularization and use
