Induced crack used for basement outer wall

Abstract

The invention discloses an induced crack used for a basement outer wall. The induced crack comprises an induced crack body, wherein a waterproof layer is arranged on the side surface of the induced crack body; a reinforcing layer is arranged on the side surface of the waterproof layer; a crack filling plate is arranged in the induced crack body and is internally provided with a steel shearing pin; the steel shearing pin is connected with the inner wall of the induced crack body; the induced crack further comprises a water stopping belt, a steel bar and a structure beam; the water stopping belt and the steel bar penetrate through the crack filling plate; the structure beam is connected with the inner wall of the induced crack body. The induced crack used for the basement outer wall has good connection structure performance, has waterproof and water-stopping functions, strong corrosion resistance and good anti-cracking effect, and can effectively prevent the outer wall from being damaged.

Description

technical field [0001] The invention relates to an induced joint, in particular to an induced joint used for basement exterior walls. Background technique [0002] With the progress of social development and technological progress, a large number of high-rise, super high-rise buildings and large public buildings have emerged in major cities across the country. With limited urban land resources, in order to meet the needs of parking spaces, civil air defense projects and transportation, underground buildings occupy an area of The area is getting larger and deeper, and the outer walls of underground buildings are getting longer and longer. In the super-long structure of the basement, cracks often appear on the reinforced concrete outer walls, although concrete expansion agents are used in most projects at present. Measures such as formulating shrinkage-compensating concrete and post-casting tape to control the cracks of the exterior wall, but still cannot better suppress the c...

[0002] With the progress of social development and technological progress, a large number of high-rise, super high-rise buildings and large public buildings have emerged in major cities across the country. With limited urban land resources, in order to meet the needs of parking spaces, civil air defense projects and transportation, underground buildings occupy an area of The area is getting larger and deeper, and the outer walls of underground buildings are getting longer and longer. In the super-long structure of the basement, cracks often appear on the reinforced concrete outer walls, although concrete expansion agents are used in most projects at present. Measures such as formulating shrinkage-compensating concrete and post-casting strips to control the cracks of the external wall, but still cannot better suppress the cracking and leakage of the external wall, resulting in higher costs for later compensation for cracks
