Detailed Description
In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, a water stop connection structure passing through a connection of a structure according to the present invention will now be described. A water stop connection structure across a structure joint, comprising: left connecting portion 1, right connecting portion 2, sealing member 5 and compressing member 7. The left connecting portion 1 is used to be buried in a left concrete structure 3. The right connecting part 2 is used for being buried in a right concrete structure 4; the sealing element 5 is an elastic part which is fixedly connected with the left connecting part 1 and the right connecting part 2 respectively; an accommodating cavity is formed in the sealing element 5; the outer wall of the sealing member 5 is adapted to abut against the supporting grooves 6 of the left concrete structure 3 and the right concrete structure 4 located at the upper and lower sides of the sealing member 5. The pressing piece 7 is a flexible piece and is located in the accommodating cavity, the pressing piece 7 is used for pressing the sealing piece 5 on the bearing bracket 6, and then the expansion joint between the left concrete structure 3 and the right concrete structure 4 is sealed by the sealing piece 5.
The utility model provides a pass through stagnant water connection structure of structure junction beneficial effect lies in, compares with prior art, the utility model discloses there is the expansion joint between left concrete structure 3 and the right concrete structure 4 in the stagnant water connection structure of passing through the structure junction. Sealing member 5 respectively with left connecting portion 1 and right connecting portion 2 fixed connection, sealing member 5 is used for the liquid of isolated expansion joint both sides. Bearing brackets 6 are arranged at the abutting positions of the left concrete structure 3 and the right concrete structure 4 and the sealing element 5. The support groove 6 can be formed by avoiding the sealing element 5 during pouring, and can also be formed by post processing. The supporting grooves 6 are distributed on the upper side and the lower side of the sealing element 5. The pressure piece 7 is arranged in a receiving chamber inside the seal 5. When the liquid pressure of expansion joint one side is great, the liquid of the great side of pressure can extrude the corresponding outer wall of sealing member 5, promotes by sealing member 5 and compresses tightly 7 to the opposite side motion, until compressing member 7 with the extrusion of sealing member 5 on the bearing groove 6 of opposite side, and then the shutoff expansion joint to pressure difference is big more, compresses tightly sealing member 7 can be inseparabler and compresses tightly sealing member 5. Since the sealing member 5 is supported by means of the left concrete structure 3 and the right concrete structure 4, the present application can be applied to a place where a pressure difference is large, compared with the case where the liquid pressure is resisted by the strength of the sealing member 5 itself.
As a specific embodiment of the water-stopping connection structure passing through the connection portion of the structure provided by the present invention, please refer to fig. 5, the upper and lower ends of the sealing member 5 have a recessed portion recessed toward the interior of the accommodating cavity; the upper end and the lower end of the pressing piece 7 are provided with grooves 14, and the grooves 14 are used for accommodating the concave parts on the corresponding sides. The right concrete structure 4 is disposed opposite to the left concrete structure 3. The seal 5 is located at the expansion joint. Both left and right ends of the sealing member 5 extend to the inside of the left concrete structure 3 and the right concrete structure 4. Because thereby need dodge sealing member 5 and form bearing groove 6 when the pouring concrete, bearing groove 6 also can form through the post processing. The bearing slots 6 may be seen as being distributed on both sides of the seal 5. Taking the case that the pressure of the liquid on the upper side of the expansion joint is large as an example, the liquid on the upper side of the expansion joint presses the sealing member 5 on the upper side, and the sealing member 5 and the pressing member 7 are only flexible members. The outer wall of the upper side of the sealing element 5 is pressed to the accommodating cavity to shrink, the pressing element 7 is pressed in the shrinking process of the sealing element 5, and then the pressing element 7 is pushed to move downwards until the pressing element 7 tightly presses the sealing element 5 on the bearing bracket 6. Because the effect of holding groove 6 has prevented compressing tightly 7 and has continued the downstream, under the effect of upside liquid, sealing member 5 closely laminates on holding groove 6 to with the shutoff of expansion joint. Because the sealing element 5 has strong ductility, the upper end and the lower end of the sealing element 5 can be provided with a concave body matched with the groove 14, and when the pressure of the liquid on the upper side is high, the concave body moves into the groove 14 and pushes the pressing element 7 to move. The purpose of the groove 14 is to stably support the end of the sealing element 5, avoiding damage due to stress concentrations when the sealing element 5 is pressed against the pressure element 7.
As a specific embodiment of the water-stopping connection structure for passing through the structure joint provided by the present invention, please refer to fig. 1, the left and right sides of the sealing member 5 are the outer convex surfaces 15 of the butt, and the outer convex surfaces 15 of the butt are used for abutting against the bearing groove 6.
