Induced joint structure for basement joint control and construction method

Abstract

The invention discloses an induced joint structure for basement joint control. A plurality of outer side horizontal bars, a plurality of inner side horizontal bars and a plurality of vertical bars arearranged inside a concrete main body; induced joints are arranged on the inner side of the inner side horizontal bars; the inner side horizontal bars break off on the two sides of the induced joints;the induced joints adopt a semi-arc structure extending vertically; an inwards concave induced joint groove is arranged at the arc midpoint of the semi-arc structure, so that under the action of theinduced joints, shrinkage cracks of the concrete main body occur according to preset traces; the vertical section where the shrinkage cracks exist is vertical to the length direction of the inner sidehorizontal bars; waterstop rings are arranged on the positions of the outer side horizontal bars on the two sides of the induced joints; a plurality of later injection pipes are vertically arranged at the vertical section wherein the induced joints are arranged. According to the invention, the technical problems that irregular cracks are generated, joint positions are uncontrollable in the basement, leakage is likely caused at the later joints and sealing is not easy to carry out, and leaked water cannot be collected, are solved.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to an induced joint structure and a construction method for basement crack control. Background technique [0002] In recent years, large-scale buildings have continuously emerged in my country, and a large part of them are ultra-long structures. Cracks are common especially in basement concrete structures due to the long length of the concrete structure. Super-long concrete structures are prone to cracking due to the dual effects of temperature stress and shrinkage stress. The temperature shrinkage cracks that are prone to appear in super-long concrete structures tend to increase gradually, and usually such cracks are irregular in shape. If the foundation is unstable, Unfavorable factors such as structural settlement, cracks will further expand, and structural water leakage will occur, which is extremely unfavorable to the service life of the underground structure,...
