The traditional method of pre-water-stopping and post-pouring concrete structure construction has long dominated, but its drawbacks have become increasingly prominent in practice.

[0003] The existing pre-sealing and post-casting construction of basement floor slabs using concrete structures has many drawbacks. Before the post-casting strip is sealed, the construction joint roughened by chiseling is difficult to clean, affecting the effective thickness of the floor slab structure and the thickness of the bottom reinforcement protective layer, which is not conducive to the structural stress and increases the risk of leakage. At the same time, in actual construction, the deformation space reserved for pre-sealing is easily filled with concrete, affecting the structural expansion and contraction deformation, increasing the probability of crack formation and leakage risk. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a U-shaped steel plate pre-water-stop post-pouring strip structure, which has the advantage of stable water-proofing. It solves the problems of existing pre-water-stop post-pouring structures for basement floor slabs using concrete construction, which have many drawbacks. For example, after the construction joint is roughened before the post-pouring strip is closed, the concrete residue is difficult to clean, affecting the effective thickness of the floor slab structure and the thickness of the bottom reinforcement protective layer, which is not conducive to the structural stress and increases the risk of leakage. At the same time, in actual construction, the deformation space reserved for pre-water-stop is easily filled with concrete, affecting the structural expansion and contraction deformation, increasing the probability of crack formation and leakage risk.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a U-shaped steel plate pre-water-stop post-pouring strip structure, comprising a retractable and deformable U-shaped steel plate, the bottom of which is coated with a waterproof layer, a gasket is installed at the bottom of which is a waterproof layer, and a water-stop filter assembly is installed at the top of which is a retractable and deformable U-shaped steel plate.

[0009] As a preferred embodiment of this utility model, the gasket is made of rubber, and an anti-slip groove is provided on the outer side of the gasket.

[0010] As a preferred embodiment of this utility model, the outer sides of the waterstop steel plate and the bending plate are coated with an anti-corrosion layer, and the outer sides of the comb-shaped template are equipped with reinforcing ribs.

[0011] As a preferred embodiment of this utility model, a waterstop strip is installed on the top of the waterstop steel plate, and a plurality of waterstop strips are provided, with the plurality of waterstop strips arranged at equal intervals.

[0012] As a preferred embodiment of this invention, the outer side of the bottom of the retractable U-shaped steel plate is arc-shaped.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model achieves stable filtration and seepage prevention by setting up a retractable and deformable U-shaped steel plate in conjunction with a waterproof layer, gaskets, and water-stop filter components. It solves the many drawbacks of the existing pre-water-stopping and post-cast concrete structure construction of basement floor slabs, which has many drawbacks. Before the post-cast strip is closed, the construction joint roughened by chiseling is difficult to clean the concrete residue, which affects the effective thickness of the floor slab structure and the thickness of the bottom reinforcement protective layer, which is not conducive to the structural stress and increases the risk of leakage. At the same time, in actual construction, the deformation space reserved for pre-water-stopping is easily filled with concrete, which affects the structural expansion and contraction deformation, increases the probability of crack formation and leakage risk, and achieves a stable seepage prevention effect.

[0015] 2. This utility model, by setting up a water-stop filter component, effectively blocks concrete debris from entering the key water-stopping area with a comb-shaped template, ensuring the cleanliness of the environment around the water-stopping steel plate and improving the water-stopping effect. At the same time, its special shape design facilitates the flow and vibration of concrete during the pouring process, ensuring the density of the concrete, enhancing the overall structure, reducing the risk of leakage caused by the non-dense concrete at the construction joint, and improving the construction quality. As a key water-stopping component, the water-stopping steel plate, with its tight structure, can effectively block the seepage path of groundwater. Compared with traditional water-stopping methods, it forms a stable water barrier after the concrete is poured due to its rigidity and integrity.

[0016] 3. This utility model, by setting up a slag-cleaning trough and a roughening trough, provides a channel for centralized collection and cleaning of concrete slag, while the roughening trough significantly enhances the friction and interlocking force between the extensible deformable U-shaped steel plate and the concrete, ensuring that the extensible deformable U-shaped steel plate can be firmly bonded to the concrete during structural stress and deformation, maintaining the stability of the water-stop structure, and effectively preventing leakage problems caused by displacement of the extensible deformable U-shaped steel plate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, the present invention provides a U-shaped steel plate pre-water-stop post-pouring strip structure, including a retractable U-shaped steel plate 1, a waterproof layer 2 sprayed on the bottom of the retractable U-shaped steel plate 1, a gasket 3 installed at the bottom of the waterproof layer 2, and a water-stop filter assembly 4 installed on the top of the retractable U-shaped steel plate 1.

[0023] refer to Figure 2 The water-stop filter assembly 4 includes a comb-shaped template 41, and a water-stop steel plate 42 is installed on the top of the comb-shaped template 41.

[0024] As a technical optimization of this utility model, by setting the water-stop filter component 4, the comb-shaped template 41 effectively blocks concrete debris from entering the key water-stop area, ensuring the cleanliness of the environment around the water-stop steel plate 42 and improving the water-stop effect. At the same time, its special shape design facilitates the flow and vibration of concrete during the pouring process, ensuring the density of concrete, enhancing the integrity of the structure, reducing the risk of leakage caused by the non-dense concrete at the construction joint, and improving the construction quality. As a key water-stop component, the water-stop steel plate 42, with its tight structure, can effectively block the seepage path of groundwater. Compared with traditional water-stopping methods, it forms a stable water barrier after the concrete is poured due to its rigidity and integrity.

[0025] refer to Figure 2The top of the telescopic deformable U-shaped steel plate 1 is provided with a slag cleaning groove 5, and the outer side of the telescopic deformable U-shaped steel plate 1 is provided with a roughening groove 6.

[0026] As a technical optimization of this utility model, by setting up a slag cleaning trough 5 and a roughening trough 6, the slag cleaning trough 5 provides a channel for centralized collection and cleaning of concrete slag, while the roughening trough 6 significantly enhances the friction and interlocking force between the extensible deformable U-shaped steel plate 1 and the concrete, ensuring that the extensible deformable U-shaped steel plate 1 can be stably bonded to the concrete during structural stress and deformation, maintaining the stability of the water-stop structure, and effectively preventing leakage problems caused by the displacement of the extensible deformable U-shaped steel plate 1.

[0027] refer to Figure 2 The internal nozzles of the slag cleaning tank 5 have an anti-stick coating 7, and the outer side of the water-stop steel plate 42 is equipped with a bent plate 8.

[0028] As a technical optimization of this utility model, by setting an anti-stick coating 7 and a bending plate 8, the anti-stick coating 7 makes it easy to remove concrete slag in the slag removal trough 5, keeping the slag removal trough 5 unobstructed, and avoiding the impact of slag accumulation on subsequent construction and structural performance. The bending plate 8 further changes the water flow path on the outside of the water-stop steel plate 42, increasing the difficulty and length of water infiltration. Working together with the water-stop steel plate 42, it forms a more rigorous water-stopping defense line, greatly enhancing the reliability of water-stopping, effectively reducing the risk of groundwater leakage into the building interior, and ensuring a dry environment in the building's underground space.

[0029] refer to Figure 3 The pad 3 is made of rubber, and the outer side of the pad 3 has an anti-slip groove 9.

[0030] As a technical optimization of this utility model, by setting a gasket 3 and an anti-slip groove 9, the rubber gasket 3 has good elasticity and cushioning performance, which can effectively absorb and disperse various impact forces and vibrations that the extensible deformable U-shaped steel plate 1 is subjected to during use, protecting the structure from damage. The anti-slip groove 9 on the outer side of the gasket 3 significantly increases the friction between the gasket 3 and the installation part, ensuring the stability of the position of the extensible deformable U-shaped steel plate 1 and related components during construction and long-term use, avoiding the impact of displacement on the water stop and structural function, and improving the reliability and durability of the entire structure.

[0031] refer to Figure 2 The outer sides of the waterstop steel plate 42 and the bending plate 8 are coated with an anti-corrosion layer 10, and the outer sides of the comb-shaped template 41 are equipped with reinforcing ribs 11.

[0032] As a technical optimization of this utility model, by setting the anti-corrosion layer 10 and the reinforcing ribs 11, the anti-corrosion layer 10 forms a protective film on the outside of the waterstop steel plate 42 and the bending plate 8, which effectively resists the erosion of groundwater, corrosive substances in the soil and humid environment, slows down the corrosion rate of metal parts, extends their service life, reduces the risk of waterstop performance degradation and structural damage caused by corrosion, and reduces the cost of later maintenance and replacement. The reinforcing ribs 11 on the outside of the comb-shaped template 41 enhance the strength and rigidity of the template, enabling it to withstand greater concrete pouring pressure and impact, preventing deformation and damage of the comb-shaped template 41, ensuring the stability and reusability of the comb-shaped template 41 during construction, and ensuring construction quality and efficiency.

[0033] refer to Figure 2 A waterstop strip 12 is installed on the top of the waterstop steel plate 42. Several waterstop strips 12 are provided, and the several waterstop strips 12 are arranged at equal intervals.

[0034] As a technical optimization of this utility model, by setting waterstop strips 12, multiple waterstop strips 12 set at equal intervals form multiple defense lines on the top of the waterstop steel plate 42, further preventing possible leakage of water, enhancing the water-stopping effect, improving the waterproof redundancy of the entire post-pouring strip structure, and providing more reliable waterproof protection for the underground structure of the building.

[0035] refer to Figure 1 The outer side of the bottom of the retractable U-shaped steel plate 1 is arc-shaped.

[0036] As a technical optimization of this utility model, by setting up a retractable deformable U-shaped steel plate 1, the arc design of the retractable deformable U-shaped steel plate 1 can better disperse stress, reduce stress concentration points, improve the load-bearing capacity and fatigue resistance of the retractable deformable U-shaped steel plate 1, ensure that the retractable deformable U-shaped steel plate 1 can work stably under long-term complex stress environment, maintain the effectiveness of the post-cast strip structure, and ensure the safety and stability of the building structure.

[0037] The working principle and usage process of this utility model are as follows: During the construction process, the expandable and deformable U-shaped steel plate 1 is first installed at the predetermined post-pouring strip position. The arc-shaped design at its bottom can automatically adjust the contact shape according to the actual stress situation when in contact with the cushion layer and surrounding structure, effectively dispersing the pressure from the upper structure and the stress caused by foundation settlement, temperature changes, etc. When the structure undergoes slight deformation, the expandable and deformable U-shaped steel plate 1 can flexibly expand and contract within a certain range due to its good elastic modulus and yield strength, avoiding structural damage or cracks caused by rigid resistance, maintaining the stability of the overall structure, and ensuring the structural safety of the post-pouring strip.

[0038] The gasket 3 installed at the bottom of the expandable and deformable U-shaped steel plate 1 utilizes the elasticity and cushioning properties of rubber to further reduce the impact of external impact on the steel plate and structure. The anti-slip groove 9 on the outer side of the gasket 3 keeps it tightly fixed in the installation position, preventing displacement due to vibration or other factors during construction and use. This ensures the accuracy and stability of the U-shaped steel plate position and lays the foundation for the subsequent water-stopping and structural functions.

[0039] The water-stop filter assembly 4 on top of the expandable and deformable U-shaped steel plate 1 plays a crucial role in water-stopping and assisting in concrete pouring. Before concrete pouring, the comb-shaped template 41, with its special toothed structure, effectively prevents concrete debris generated during construction from entering the critical water-stopping area, avoiding debris accumulation that could affect the water-stopping effect. During concrete pouring, the shape design of the comb-shaped template 41 facilitates uniform concrete flow and thorough vibration, ensuring the compactness of the concrete at construction joints, enhancing the overall structural integrity, and reducing the risk of leakage. The water-stop steel plate 42, installed on top of the comb-shaped template 41, becomes an important barrier against groundwater seepage due to its rigidity and tight structure. The water-stop steel plate 42 works closely with the expandable and deformable U-shaped steel plate 1 to form a continuous water-stopping defense line. The outer bending plate 8 changes the water flow path, increasing the difficulty and length of water seepage. Working in conjunction with the water-stop steel plate 42, it effectively reduces the risk of groundwater leakage into the building. The multiple water-stop strips 12 set at equal intervals on the top of the water-stop steel plate 42 can fill the gaps in time if there are any small gaps or local defects in the water-stop steel plate 42, further enhancing the water-stopping effect and improving the waterproof redundancy of the entire post-cast strip structure.

[0040] The slag-cleaning groove 5 at the top of the expandable and deformable U-shaped steel plate 1 provides a centralized channel for cleaning concrete slag. The anti-stick coating 7 inside the slag-cleaning groove 5 reduces the adhesion between the concrete slag and the groove wall, making it easy for construction personnel to clean the slag during construction or subsequent maintenance, keeping the slag-cleaning groove 5 unobstructed, and avoiding the impact of slag residue on structural performance and subsequent construction. The rough groove 6 on the outside of the expandable and deformable U-shaped steel plate 1 significantly enhances the friction and interlocking force between the steel plate and the concrete after the concrete is poured, ensuring that the expandable and deformable U-shaped steel plate 1 can be firmly bonded to the concrete during structural stress and deformation, maintaining the stability of the water-stop structure, and effectively preventing leakage problems caused by steel plate displacement.

[0041] The anti-corrosion layer 10 sprayed on the outside of the waterstop steel plate 42 and the bent plate 8 can effectively isolate the metal parts from groundwater, corrosive substances in the soil, and humid environments. By forming a protective film, it slows down the corrosion rate of the metal, extends the service life of the waterstop components, reduces the risk of waterstop performance degradation and structural damage caused by corrosion, reduces the cost of later maintenance and replacement, and ensures the continuous effectiveness of the waterstop function during the long-term use of the building. The reinforcing ribs 11 installed on the outside of the comb-shaped template 41 enhance the strength and rigidity of the template, enabling it to withstand greater concrete pouring pressure and impact, preventing the template from deforming and being damaged during construction, ensuring the stability and reusability of the template during construction, and ensuring construction quality and efficiency.

[0042] In summary, this U-shaped steel plate pre-water-stop post-pouring strip structure, through the use of a retractable U-shaped steel plate 1 in conjunction with a waterproof layer 2, gasket 3, and water-stop filter assembly 4, provides stable filtration and seepage prevention. This solves the numerous drawbacks of existing pre-water-stop post-pouring structures for basement slabs constructed with concrete. For example, before the post-pouring strip is sealed, the construction joint roughened by chiseling makes it difficult to clean the concrete residue, affecting the effective thickness of the slab structure and the thickness of the bottom reinforcement protective layer, which is detrimental to structural stress and increases the risk of leakage. Furthermore, in actual construction, the pre-water-stop deformation space is easily filled with concrete, affecting structural expansion and contraction, increasing the probability of crack formation and leakage risk.
