The invention discloses an induced joint structure for crack control in a basement. The concrete main body is provided with: several outer horizontal bars, several inner horizontal bars and several vertical steel bars, the inner horizontal bar has an induced joint inside, and the inner horizontal bar is on both sides of the induced joint Disconnected, the induced joint is a semi-arc structure extending longitudinally, and the midpoint of the semi-arc structure has an inwardly recessed guide joint groove, so that the shrinkage crack of the concrete main body follows a predetermined track under the action of the induced joint Formation, the vertical section where the shrinkage crack is located is perpendicular to the length direction of the inner horizontal bar, the outer horizontal bar is located on both sides of the shrinkage crack, and water-stop rings are installed, and the vertical section where the shrinkage crack is located is provided with a number of late-stage grouting from top to bottom The tube solves the technical problems of many irregular cracks in the basement and uncontrollable crack positions in the above-mentioned prior art, leakage may occur at the induced cracks in the later stage and it is not easy to seal, and at the same time, the technical problems that the leaking water cannot be collected.
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,...
