Abstract
The utility model relates to an expansion water stop belt for a basement construction joint, which comprises a rubber main body and a plurality of expansion water stop units, wherein the expansion water stop units are arranged on the upper side surface of the rubber main body, each expansion water stop unit comprises a flexible steel groove and a water absorption expansion strip, the bottom of each flexible steel groove is fixedly connected to the rubber main body, the upper-end notch of each flexible steel groove is turned inwards and clamps the water absorption expansion strip, and the bottom surface of each water absorption expansion strip is higher than the bottom of each flexible steel groove. Utilize flexible steel channel increase water swelling strip's inflation deformation space in, can let the inlet opening with the bottom of water infiltration water swelling strip, increase the contact surface of water swelling strip and water to increase its inflation speed, and set up the wash port at the downside of rubber main part, under water swelling strip inflation state, the wash port is by the elastic extrusion, under anhydrous state, the wash port resumes, ensures the quick dry state that resumes of water swelling strip department.
Description
Technical Field
The utility model relates to an expansion water stop for a basement construction joint.
Background
With the popularization of automobiles in recent years, various related civil buildings have higher and higher requirements on parking spaces, basements need to be constructed in the construction process of various projects to meet the parking requirements, various construction technical problems of the basements can be met in the construction process of many projects at present, particularly the waterproof problem of the construction joints of the basements is solved, the construction joints of the basements generally adopt a steel plate water stop belt or a water-swelling water stop strip mode at present, the steel plate water stop belt has the problems of poor metal compression deformation capability and more metal welding seams, a new defect is easy to form between interfaces when a concrete component deforms, the water-swelling water stop strip has the problems of large compression rebound of water-swelling rubber, small compression denaturation capability, poor sealing for filling small gaps and the like. The expansion strip expands in the presence of water. But this does not occur immediately but slowly over several hours after contact with water.
Disclosure of Invention
The utility model aims to solve the problems and provides an expansion water stop for a basement construction joint, which is realized by the following technical scheme:
the utility model provides a basement construction joint expansion waterstop, includes rubber main part and a plurality of inflation stagnant water unit, inflation stagnant water unit sets up the side of going up of rubber main part, inflation stagnant water unit includes flexible steel groove and the inflation strip that absorbs water, and flexible steel groove bottom fixed connection is in rubber main part, and the upper end notch of flexible steel groove turns over inwards and the centre gripping the inflation strip that absorbs water, the bottom surface of the inflation strip that absorbs water is higher than the tank bottom of flexible steel groove.
The expansion water stop belt for the basement construction joint is further designed in that a drain hole opposite to the expansion water stop unit is formed in the lower side of the rubber main body, and a water permeable hole communicated with the drain hole is formed in the bottom of the flexible steel groove.
The expansion water stop for the basement construction joint is further designed in a manner that a connecting hole is longitudinally arranged in the middle of the rubber main body in a penetrating mode.
The expansion water stop for the basement construction joint is further designed in that a water inlet hole is formed in the side wall of the flexible steel groove.
The utility model has the beneficial effects that:
utilize flexible steel channel increase water swelling strip's inflation deformation space in, can let the inlet opening with the bottom of water infiltration water swelling strip, increase the contact surface of water swelling strip and water to increase its inflation speed, and set up the wash port at the downside of rubber main part, under water swelling strip inflation state, the wash port is by the elastic extrusion, under anhydrous state, the wash port resumes, ensures the quick dry state that resumes of water swelling strip department.
Drawings
Fig. 1 is a schematic view of the overall structure of the embodiment of the present invention.
Fig. 2 is a schematic structural diagram of an expansion water stop unit.
Detailed Description
The utility model is further illustrated by the following figures and examples in conjunction with the description:
as shown in the figure, basement construction joint expansion waterstop, including rubber subject 1 and a plurality of inflation stagnant water unit 2, inflation stagnant water unit sets up the side of going up of rubber subject, inflation stagnant water unit 2 includes flexible steel groove 21 and the inflation strip that absorbs water 22, and flexible steel groove bottom fixed connection is in rubber subject, and the upper end notch in flexible steel groove turns over inwards and the centre gripping the inflation strip that absorbs water, the bottom surface of inflation strip that absorbs water is higher than the tank bottom in flexible steel groove.
The space that the flexible steel groove of this embodiment is located water absorption expansion strip bottom side can increase water absorption expansion strip's expansion deformation space and elasticity expansibility to have better inflation stagnant water effect, and because the space in flexible steel groove, avoid the water absorption expansion strip and the concrete between the inflation extrusion produce the phenomenon of ulcerate.
The lower side of the rubber main body is provided with a drain hole 11 opposite to the expansion water stop unit, and the bottom of the flexible steel groove is provided with a water permeable hole 12 communicated with the drain hole. And the middle part of the rubber main body is longitudinally provided with a connecting hole 3 in a through manner. Can let the inlet opening with the bottom of water infiltration water swelling strip, the increase water swelling strip and the contact surface of water to increase its inflation speed.
The water inlet 4 is formed in the side wall of the flexible steel groove, the drain hole is formed in the lower side of the rubber main body, the drain hole is elastically extruded in the expansion state of the water absorption expansion strip, and the drain hole is recovered in the anhydrous state, so that the water absorption expansion strip is enabled to recover to the dry state quickly.
Claims (4)
1. The utility model provides a basement construction joint inflation waterstop, its characterized in that includes rubber main part and a plurality of inflation stagnant water unit, inflation stagnant water unit sets up the side of going up of rubber main part, inflation stagnant water unit includes flexible steel groove and the inflation strip that absorbs water, and flexible steel bottom of the groove portion fixed connection is in rubber main part, and the upper end notch in flexible steel groove turns over inwards and the centre gripping the inflation strip that absorbs water, the bottom surface of the inflation strip that absorbs water is higher than the tank bottom in flexible steel groove.
