Technical Field
[0001] The utility model relates to the field of basement anti-leakage structures, in particular to a basement anti-leakage structure. Background Art
[0002] A basement is a room whose floor is lower than the outdoor ground level by more than half of the room's net height. Multi-story and high-rise buildings require a deeper foundation. To utilize this height, a basement is built under the ground floor of the building, which can increase the usable area and save the backfill soil in the center of the house. At the same time, building a basement below the ground floor of the house can improve the efficiency of building land use.
[0003] As an indispensable part of basement construction, expansion joints not only play a role in regulating temperature and humidity, but also bear the responsibility of bearing the weight of the building itself. However, due to problems in the design, construction, and materials of expansion joints, leakage is likely to occur. In order to solve the above problems, plastic waterstops are often preset in the expansion joints and locked with integrated external fixings. When the expansion joints are slightly deformed due to large external temperature differences or concrete settlement, the integrated external fixings are easily damaged under stress. At the same time, traditional waterstops are one-way sealed to prevent leakage, and the overall sealing effect is poor. Utility Model Content
[0004] Aiming at the problems in the prior art that the integrated external fixing parts are easy to deform and the overall sealing effect is poor, the utility model provides a basement anti-leakage structure.
[0005] The technical solution adopted by the utility model to solve the technical problem is: a basement anti-leakage structure, comprising:
[0006] A water stop member, wherein the water stop member retains a transverse water stop strip and a longitudinal water stop strip, the transverse water stop strip is horizontally pre-buried in the concrete wall, the longitudinal water stop strip is symmetrically arranged at the center position of the transverse water stop strip, and the longitudinal water stop strip is located in the expansion joint;
[0007] A positioning member, wherein the positioning member comprises a positioning plate, a connecting plate, a circular groove and a cylindrical block.

A connecting plate is arranged at the inclined surface of each positioning plate. A circular groove is provided on the end surface of one of the connecting plates at the same side. A cylindrical block is arranged at the end surface of the other connecting plate at the same side. The cylindrical block and the circular groove cooperate with each other. The inclined surfaces of the positioning plate and the connecting plate are in conflict with each other and are fixed by bolts.
[0008] The cylindrical block and the circular groove gap are combined to form a positioning seam, and a first sealing strip is connected to the center of the end of the longitudinal water stop strip, and the first sealing strip is located in the positioning seam.
[0009] Specifically, the end of the longitudinal water stop strip is symmetrically connected to the second sealing strip, and the second sealing strip is located between the positioning plate and the concrete wall.
[0010] Specifically, a third sealing strip is fixedly connected to the end of the longitudinal water stop strip and is located between the first sealing strip and the second sealing strip, and the third sealing strip is located at the contact surface between the positioning plate and the connecting plate.
[0011] Specifically, the contact surfaces of the positioning plate and the connecting plate are respectively provided with a first semicircular groove and a second semicircular groove, a limiting block is installed in the second semicircular groove, and a partial area of the third sealing strip is located between the first semicircular groove and the limiting block.

[0015] Beneficial effects of the utility model:
[0016] The utility model discloses a basement anti-leakage structure. Compared with the traditional integrated external fixation, the utility model adopts a spliced positioning piece. When the external temperature changes and causes the wall to expand and contract, settle and the like, the two connecting plates on the same side can be relatively deflected. Specifically, the cylindrical block rotates on the inner wall of the circular groove. During the relative deflection of the two, the first sealing strip is always in the positioning seam. In this way, it can be ensured that the positioning piece will not be deformed and damaged when the above phenomenon occurs.
[0017] The utility model describes a basement anti-leakage structure. The water stop of the utility model is of special-shaped design.

DETAILED DESCRIPTION
[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0025] In addition, the terms used below are defined based on the functions of the present invention and may differ depending on the intention or custom of the user or operator. Therefore, these terms are defined based on the entire contents of this specification.
[0026] See also Figure 1-4 The utility model discloses a basement anti-leakage structure, comprising a water stop member 1 and a positioning member 2. The water stop member 1 retains a transverse water stop strip 11 and a longitudinal water stop strip 12. The transverse water stop strip 11 is horizontally pre-buried in the concrete wall, that is, the transverse water stop strip 11 is placed inside during the cast-in-place process of the basement wall. The longitudinal water stop strip 12 is symmetrically arranged at the center of the transverse water stop strip 11. The longitudinal water stop strip 12 is located in the expansion joint. This method performs a cross-seal on the expansion joint, and the overall anti-leakage effect is better.
[0027] The positioning member 2 includes a positioning plate 21, a connecting plate 22, a circular groove 23 and a cylindrical block 24. The positioning member 2 is used to lock and fix the water stop member 1. In this way, the overall sealing of the water stop member 1 relative to the expansion joint can be ensured, thereby improving the anti-leakage effect;
[0028] The positioning plate 21 is fixedly installed on one side of the concrete wall by expansion bolts. The cross section of the positioning plate 21 is a right-angle trapezoid. A connecting plate 22 is arranged at the inclined surface of each positioning plate 21. A circular groove 23 is opened at the end surface of one of the connecting plates 22 on the same side. A cylindrical block 24 is arranged at the end surface of the other connecting plate 22 on the same side. The cylindrical block 24 and the circular groove 23 cooperate with each other. The inclined surfaces of the positioning plate 21 and the connecting plate 22 are in contact and fixed by bolts. The gap between the cylindrical block 24 and the circular groove 23 is combined. A positioning joint is formed, and a first sealing strip 13 is connected to the center of the end of the longitudinal water stop strip 12, and the first sealing strip 13 is located in the positioning joint. When the external temperature changes and causes the wall to expand and contract, settle, and the like, the two connecting plates 22 on the same side can be deflected relative to each other. Specifically, the cylindrical block 24 rotates on the inner wall of the circular groove 23. During the relative deflection of the two, the first sealing strip 13 is always in the positioning joint. This method can ensure that when the above-mentioned phenomenon occurs, the positioning member 2 will not be deformed and damaged.
[0029] See also Figure 1 and Figure 2 The end of the longitudinal water stop strip 12 is symmetrically connected with a second sealing strip 14, and the second sealing strip 14 is located between the positioning plate 21 and the concrete wall. The second sealing strip 14 increases the tightness of the connection between the positioning plate 21 and the concrete wall, and the second sealing strip 14 can be regarded as a primary anti-leakage cushion layer, which increases the path length of foreign matter entering the expansion joint, further improving the sealing effect.
[0030] See also Figure 1-Figure 3 A third sealing strip 15 is fixedly connected to the end of the longitudinal water stop strip 12 and is located between the first sealing strip 13 and the second sealing strip 14, and the third sealing strip 15 is located at the contact surface of the positioning plate 21 and the connecting plate 22. The third sealing strip 15 can be regarded as a secondary anti-leakage cushion layer, and the water stop member 1, the first sealing strip 13, the second sealing strip 14 and the third sealing strip 15 are an integral part, which are synthesized through high-temperature melting. The third sealing strip 15 further increases the path length of foreign matter entering the expansion joint, and the anti-leakage effect of the expansion joint is further improved.
[0031] See also Figure 1-Figure 3 The contact surfaces of the positioning plate 21 and the connecting plate 22 are respectively provided with a first semicircular groove 211 and a second semicircular groove 212, a limiting block 213 is installed in the second semicircular groove 212, and a partial area of the third sealing strip 15 is located between the first semicircular groove 211 and the limiting block 213. The third sealing strip 15 is pressed tightly into the first semicircular groove 211 by the limiting block 213, thereby increasing the fixing tightness of the third sealing strip 15 and ensuring that the third sealing strip 15 will not loosen. At the same time, the sealing between the third sealing strip 15 and the positioning plate 21 and the connecting plate 22 can be increased.
[0032] See also Figure 1 and Figure 4 The outer wall of the transverse water stop strip 11 is provided with protrusions 111 at equal intervals on both sides. The contact area between the transverse water stop strip 11 and the concrete wall is increased by the protrusions 111, thereby increasing the embedded firmness of the transverse water stop strip 11.
[0033] See also Figure 1-Figure 3 , an inner groove 221 is provided in a partial area of the outer wall of the circular groove 23, and a partial area of the first sealing strip 13 is closely attached to the inner groove 221, and a supporting sponge 222 is bonded to the position of the circular groove 23 facing the inner groove 221, and the outer side of the supporting sponge 222 is closely attached to the outer wall of the first sealing strip 13. In the initial state, the first sealing strip 13 located in the inner groove 221 can be understood as a relaxed state. When the cylindrical block 24 is relatively deflected relative to the circular groove 23, the first sealing strip 13 moves synchronously with the relative deflection of the cylindrical block 24 under the action of friction. At this time, the first sealing strip 13 located in the inner groove 221 is partially stretched, so that the first sealing strip 13 located in the positioning seam will not be deformed, thereby ensuring that the first sealing strip 13 will not be damaged by excessive deformation. The supporting sponge 222 shrinks synchronously after the first sealing strip 13 is stretched, and completely fills the space between the first sealing strip 13 and the circular groove 23, and the position is sealed.
[0034] See also Figure 2 A sealing sponge 223 is installed at the connection between the circular groove 23 and the cylindrical block 24. Under the condition that the circular groove 23 and the cylindrical block 24 can be relatively deflected, the sealing sponge 223 is used to seal the circular groove 23 and the cylindrical block 24.
