Description

FIELD OF THE DISCLOSURE

The present disclosure relates to the technical filed of building waterproof structures, and more particularly to a building deformation joint waterproofing system with a bonding-type built-in water stop structure, and a method based thereon.

BACKGROUND OF THE DISCLOSURE

The “deformation joint” is the general term for an expansion joint, a settlement joint, and a seismic joint. Buildings are often deformed due to external factors, leading to cracking or even damage. In view of this situation, the deformation joints are reserved as construction joints. The national standard GB50108 “Technical Code for Waterproofing of Underground Works” has clear provisions for the waterproofing construction of deformation joints in underground engineering, and it is mandatorily stipulated that the buried water stop is a waterproof measure that must be adopted in the deformation joint. The water stop, coupled with waterproof measures for front and back water surfaces, forms a deformation joint waterproofing system. Such a practice has been implemented in our country for more than half a century, and is also a common practice internationally.

As the most difficult waterproof problem in detail construction, waterproofing for the deformation joints is realized by closely attaching the water stop to the concrete in the prior art. However, such a waterproofing solution has a big problem that there are moving gaps between the water stop and the concrete. Under the external pressure, water enters the interior through the gaps between the rubber-plastic water stop and the concrete, resulting in a low success rate of a building deformation joint waterproofing project. Thus, it is said that “Nine out of ten seams leak”. Moreover, once the building deformation joint waterproofing project is leaked, maintenance is rather difficult and the project cannot be fully repaired. Therefore, it is in urgent need to develop a stable and reliable building deformation joint waterproofing system which has a good waterproof effect and is easy in maintenance.

SUMMARY OF THE DISCLOSURE

In view of the shortcomings and deficiencies in the prior art, the present disclosure aims to provide a building deformation joint waterproofing system with a bonding-type built-in water stop structure, which bonds the water stop structure to the two inner wall sides of a building deformation joint with an adhesive to form a seamless waterproof construction, thus greatly improving the waterproof ability of the building deformation joint. Moreover, the system designs a protection structure on a concrete structure, so that the building deformation joint can resist a high water pressure and further can prevent foreign matters from entering the water stop structure, thus having the advantages of a stable waterproof structure, a good waterproof effect, a wide range of application, strong waterproof reliability, a simple structure, easy implementation and operation, easy maintenance, and a long service life.

To achieve the foregoing objective, the present disclosure adopts the following technical solutions:

A building deformation joint waterproofing system with a bonding-type built-in water stop structure is provided, which includes: a concrete structure, on which a building deformation joint is disposed; a water stop structure, which is elastic or stretchable, and disposed in the building deformation joint; and a first bonding layer, disposed between the water stop structure and an inner wall of the building deformation joint.

Preferably, the water stop structure includes: an elastic supporter; and a high polymer roll material which is elastic and disposed in the supporter, where during bonding between the water stop structure and the inner sidewalls of the deformation joint, the water stop structure is pressed against the inner sidewalls of the building deformation joint under the elastic effect of the supporter and the high polymer roll material.

Preferably, the high polymer roll material has an M-shaped or W-shaped cross section.

Preferably, at least the face close to the concrete structure among all faces of the high polymer roll material is designed into a concave and convex face, and the concave and convex face can enhance the strength of connection with the first bonding layer.

Preferably, mutually close sides on the high polymer roll materials of a plurality of adjacent water stop structures are all provided with protruding parts; and a connector which matches the shape of the cross section of the high polymer roll material is fixedly connected to wide surfaces of the protruding parts of the multiple high polymer roll materials, so as to realize connection between two adjacent water stop structures.

Preferably, the connector is connected to the protruding parts of the multiple high polymer roll materials by means of sweat soldering.

Preferably, the connector and the protruding parts of the multiple high polymer roll materials are connected via a second bonding layer.

Preferably, the connector is cross-shaped or T-shaped, or a right-angle shape.

Preferably, the supporter is made from memory foam.

Preferably, the two sidewalls of the building deformation joint on the concrete structure are both provided with recesses; and during bonding between the water stop structure and the building deformation joint, the recesses are filled with an adhesive, and the adhesive is integrally formed with the first bonding layer to serve as snags of the first bonding layer.

Preferably, the building deformation joint waterproofing system further includes: a protection structure; and the protection structure is disposed on an outer wall of the concrete structure, located at the two sides of the building deformation joint, and configured to resist the water pressure and protect the water stop structure.

Preferably, the concrete structure is provided with a fastening hole; and the protection structure includes: a high polymer roll material isolation layer, adhering to the sidewall of the concrete structure; a protection layer, adhering to a side of the high polymer roll material isolation layer away from the concrete structure; and a fastener, passing through the protection layer and the high polymer roll material isolation layer successively to be engaged with the fastening hole.

Preferably, the concrete structure is provided with a groove for accommodating the protection structure, the groove is filled with a concrete layer, and a sealing layer is disposed between sidewalls of the groove and the concrete layer.

Preferably, the protection layer is a steel plate and has a thickness of 8 mm. The present disclosure achieves the following beneficial effects by using the foregoing technical solution:

1. The water stop structure and the building deformation joint are bonded with an adhesive, to form a seamless waterproof construction, thus greatly improving the waterproof ability and reliability of the building deformation joint and further facilitating maintenance. The maintenance and refurbishment can be performed after debonding with hot wind.

2. Transverse recesses are made on the sidewalls of the building deformation joint, and are filled with the adhesive. The adhesive in the recesses is integrated with the first bonding layer after curing and enables the first bonding layer to be embedded in the concrete structure, thus improving the stability and reliability of the waterproof structure.

3. The protection structure is disposed on the concrete structure. On one hand, the protection layer on the protection structure is configured to resist the water pressure, thus greatly improving the resistance of the waterproofing system to the water pressure and further widening the scope of application of the waterproofing system. On the other hand, the design of the high polymer roll material isolation layer separates the exterior space from the interior space of the building deformation joint, thus preventing entering of foreign matters and prolonging the service life of the waterproofing system.

4. Joints between the multiple high polymer roll materials are easily damaged in a connection manner in the prior art, significantly reducing the tolerance of the water stop structure to the water pressure; and a remedy (Drainage, instead of waterproofing, is adopted, and is implemented in the underground project) to this problem further causes damage to the concrete. Thus, the present disclosure adopts sweat soldering or bonding to connect the multiple water stop structures, which solves the foregoing problems in the prior art; and further, achieves high strength at the connecting ends and is able to tolerate a large degree of deformation, thus being more applicable to the underground project.

In view of the shortcomings and deficiencies in the prior art, the second objective of the present disclosure is to provide a method which is configured to construct the foregoing waterproofing system; and the method has the advantages of a simple construction process, easy operation, little interference from the environment, and few construction procedures.

The construction of the building deformation joint waterproofing system by using the foregoing method is conducted after the concrete structure is completely solidified, thus avoiding cross-operation with other types of work and disturbance caused by humid operation. Moreover, this construction method is rather simple and has low requirements on an operator, thus reducing the influence of human factors on the construction quality and further saving the labor cost. In addition, the construction method of the waterproofing system has few procedures and is easily monitored, thus greatly shortening the construction period. The method has the advantages of little interference from the environment, a low labor cost, few construction procedures, a short construction period, and a simple construction process.

In view of the shortcomings and deficiencies in the prior art, the third objective of the present disclosure is to provide a method which is configured to construct the foregoing waterproofing system and aims to set up two waterproof structures respectively on a front water surface and a back water surface.

Those skilled in the art can make modifications without any creative contribution to this embodiment as needed after reading the specification. As long as the modifications fall within the scope of the claims of the present disclosure, they are all protected by the patent law.

This embodiment relates to a building deformation joint waterproofing system with a bonding-type built-in water stop structure, which, as shown in FIGS. 1 to 5, includes: a concrete structure 100, a water stop structure 200, and a first bonding layer 300.

Specifically, a building deformation joint is disposed on the concrete structure 100. The water stop structure 200 is elastic and disposed in the building deformation joint. The first bonding layer 300 is disposed between the water stop structure 200 and an inner wall of the building deformation joint.

Further, as shown in FIGS. 1 and 2, the water stop structure 200 includes a supporter 210, and a high polymer roll material 220 disposed in the supporter 210. The high polymer roll material 220 and the supporter 210 are both elastic. During bonding between the water stop structure 200 and the inner sidewalls of the deformation joint, the water stop structure is pressed against the inner sidewalls of the building deformation joint under the elastic effect of the supporter 210 and the high polymer roll material 220.

Preferably, the high polymer roll material 220 has an M-shaped or W-shaped cross section. The supporter 210 is provided with a deformation groove 201, so that the supporter 210 easily has elastic deformation.

It should be noted that, the M-shaped or W-shaped high polymer roll material 220 has high elasticity due to its structural design. When the high polymer roll material 220 is compressed to contract, the deformation groove 201 is also compressed to contract under the effect of the high polymer roll material 220. In this case, sidewalls of the deformation groove 201 get close or even adhere to each other, and restore to the original shape after the deformation. Such designed deformation groove 201 makes it easy for a filling layer to deform with the deformation of the high polymer roll material 220, thus facilitating installation of the water stop structure 200.

In this embodiment, the high polymer roll material 220 is a PVC roll material with a long service life, the first bonding layer 300 is a modified epoxy adhesive, and the supporter is made from memory foam. On the premise of achieving support to maintain the shape of the high polymer roll material 220, the use of the memory foam as the material of the supporter further achieves good elasticity and makes it unnecessary to use a clamp to hold and deform the water stop structure 200 and stuff it into the building deformation joint, thus simplifying construction steps and reducing the construction difficulty.

As shown in FIG. 4, preferably, at least the face close to the concrete structure 100 among all faces of the high polymer roll material 220 is designed into a concave and convex face 221, and the concave and convex face 221 can enhance the strength of connection with the first bonding layer. The concave and convex face 221 has a serrated or wavy cross section. In this embodiment, the wide surface of the high polymer roll material 220 is uniformly provided with the concave and convex face 221 which has a serrated cross section.

Further, mutually close sides on the high polymer roll materials 220 of a plurality of adjacent water stop structures 200 are provided with protruding parts. A connector which matches the shape of the cross section of the high polymer roll material 220 is uniformly and fixedly connected to wide surfaces of the protruding parts of the multiple high polymer roll materials 220, so as to realize connection between two adjacent water stop structures 200. Preferably, the connector is an M-shaped or W-shaped PVC roll material.

Joints between the multiple high polymer roll materials 220 are easily damaged in a connection manner in the prior art, significantly reducing the tolerance of the water stop structure 200 to the water pressure; and a remedy (Drainage, instead of waterproofing, is adopted, and is implemented in the underground project) to this problem further causes damage to the concrete. Thus, the connection structure of the present disclosure solves the foregoing problems in the prior art; and further, achieves high strength at the connecting ends and is able to tolerate a large degree of deformation, thus being more applicable to the underground project.

In this embodiment, as shown in FIG. 6, the connector is connected to the protruding parts of the multiple high polymer roll materials 220 by means of sweat soldering.

In other embodiments, as shown in FIG. 7, the connector and the protruding parts of the multiple high polymer roll materials 220 are connected via a second bonding layer, where the second bonding layer has a thickness less than or equal to 0.1 mm.

As shown in FIGS. 8 to 12, the connector is cross-shaped or T-shaped, or a right-angle shape.

Preferably, as shown in FIGS. 1 and 2, the two sidewalls of the building deformation joint on the concrete structure 100 are both provided with recesses 102. During bonding between the water stop structure 200 and the building deformation joint, the recesses 102 are filled with an adhesive, and the adhesive in the recesses 102 is integrally formed with the first bonding layer 300 to serve as snags 400 of the first bonding layer 300. After curing, the adhesive in the recesses 102 is integrated with the first bonding layer 300, and the snags 400 are embedded in the concrete structure 100, thus effectively preventing sand from being stripped off the surface of the concrete structure 100 and firmly bonding the water stop structure 200 in the building deformation joint.

Further, as shown in FIG. 2, the building deformation joint waterproofing system further includes a protection structure 500 which is disposed on an outer wall of the concrete structure 100 and is located at the two sides of the building deformation joint. The protection structure 500 is configured to resist the water pressure and protect the water stop structure 200.

Specifically, as shown in FIG. 2, the concrete structure 100 is provided with a fastening hole 101. The protection structure 500 includes a high polymer roll material isolation layer 520, a protection layer 510, and a fastener 530. The high polymer roll material isolation layer 520 adheres to the sidewall of the concrete structure 100, the protection layer 510 adheres to a side of the high polymer roll material isolation layer 520 away from the concrete structure 100, and the fastener 530 passes through the protection layer 510 and the high polymer roll material isolation layer 520 successively and is engaged with the fastening hole 101.

In this embodiment, the protection layer 510 is a steel plate and has a thickness of 8 mm. The fastening hole 101 is a threaded hole, the fastener 530 is an M12 internal expansion bolt, and a gasket is disposed between the bolt and the protection layer 510.

Preferably, the concrete structure 100 is provided with a groove for accommodating the protection structure 500, the groove is filled with a concrete layer, and a sealing layer is disposed between sidewalls of the groove and the concrete layer. Preferably, the sealing layer is formed after solidification of polysulfide sealing paste.

A design principle of this embodiment is roughly described as follows: The water stop structure 200 and the building deformation joint are bonded by using an adhesive, to form a seamless waterproof construction, thus greatly improving the waterproof ability of the building deformation joint. Moreover, the design of the protection structure 500 on the concrete structure 100 enables the building deformation joint to resist a high water pressure and further can prevent foreign matters from entering the water stop structure 200, thus having the advantages of a stable waterproof structure, a good waterproof effect, a wide range of application, strong waterproof reliability, a simple structure, easy implementation and operation, and a long service life.

Based on the foregoing technical solution, this embodiment further provides a method which is configured to construct the foregoing waterproofing system and aims to install a water stop structure 200. The method has the advantages of a simple construction process, easy operation, little interference from the environment, and few construction procedures. The method includes the following steps:

S11: building the concrete structure 100 and pre-mounting the filling plate; and preparing the water stop structure 200, a diamond saw blade, perforating equipment, a measuring tool, and an adhesive; S12: cutting recesses 102 on one side of the concrete structure 100 by using the diamond saw blade, and using a measuring tool to enable the recesses 102 to be distributed on the sidewalls of the building deformation joint at equal intervals and to ensure the recesses 102 to have identical sizes;

S13: removing part of the filling plate at the end of the building deformation joint, stuffing the water stop structure 200 into the building deformation joint, and pressing one side of the water stop structure 200; and coating the inner wall of the building deformation joint with the adhesive and further coating the other side of the water stop structure 200 with the adhesive in the same manner;

S14: under the elastic effect of the supporter 210 and the high polymer roll material 220, the water stop structure 200 being tightly pressed against the inner wall of the building deformation joint, till the water stop structure 200 is bonded to the inner wall of the building deformation joint, to form the first bonding layer 300;

S15: filling the recesses 102 with the adhesive to make the adhesive adhere to the first bonding layer 300, till the adhesive in the recesses 102 is cured to form snags 400 of the first bonding layer 300 which are embedded in the concrete structure 100;

S16: checking the first bonding layer 300 and the snags 400 and adding the adhesive to missed areas;

S17: making the fastening hole 101 on the concrete structure 100 by using the perforating equipment, adhering an isolation layer of the high polymer roll material 220 to the sidewall of the concrete structure 100, then adhering the protection layer 510 to the sidewall of the isolation layer of the high polymer roll material 220, and finally, passing the fastener 530 through the protection layer 510 and the isolation layer of the high polymer roll material 220 successively to be engaged with the fastening hole 101, as shown in FIG. 13, thus completing building of a top plate and sidewalls in the building deformation joint waterproof structure;

The construction of the building deformation joint waterproofing system by using the foregoing method is conducted after the concrete structure 100 is completely solidified, thus avoiding cross-operation with other types of work and disturbance caused by humid operation. Moreover, this construction method is rather simple and has low requirements on an operator, thus reducing the influence of human factors on the construction quality and further saving the labor cost. In addition, the construction method of the waterproofing system has few procedures and is easily monitored, thus greatly shortening the construction period. The method has the advantages of little interference from the environment, a low labor cost, few construction procedures, a short construction period, and a simple construction process.

Based on the foregoing technical solution, this embodiment further provides another method which is configured to construct the foregoing waterproofing system and aims to set up two waterproof structures respectively on a front water surface and a back water surface. This method has the advantages of a strong waterproof effect, a simple construction process, easy operation, little interference from the environment, and few construction procedures.

S22: cutting recesses 102 on one side of the concrete structure 100 by using the diamond saw blade, and using a measuring tool to enable the recesses 102 to be distributed on the sidewalls of the building deformation joint at equal intervals and to ensure the recesses 102 to have identical sizes;
