Description

Technical Field

[0001] This utility model relates to the field of waterproof structure technology, and in particular to a waterproof structure for basement floor slabs. Background Technology

[0002] When basement floor slabs crack and leak, existing sealing techniques involve injecting resin into the cracks. However, relying solely on resin is unreliable; for example, insufficient resin filling or voids within the cracks can affect the sealing effect, potentially leading to recurring leaks. Therefore, it is necessary to propose a waterproof structure to improve the reliability of the sealing process. Utility Model Content

[0003] To address the shortcomings of existing leak-sealing methods in terms of reliability, this invention proposes a waterproof structure that improves the reliability of leak sealing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A waterproof structure for basement floor slabs is disclosed for sealing cracks in the floor slab. The floor slab has a grinding groove on the upper side of the crack, with the upper ends of the groove walls on both sides sloping inwards. The waterproof structure includes resin, a steel plate, a waterproof coating, a support shaft, and elastic elements. The resin fills the crack, and the steel plate is adhered to the bottom of the grinding groove through the waterproof coating. The support shaft is slidably connected to the upper sides of the left and right ends of the steel plate. The elastic elements apply elastic force to the support shaft, which is in a supported state. In this supported state, the ends of the support shaft at both ends of the steel plate are respectively supported on the groove walls on the left and right sides of the grinding groove. Concrete is poured onto the upper side of the steel plate.

[0006] With the above setup, the resin acts as a water-blocking agent, and the waterproof coating acts as a water-retaining agent, preventing water from seeping upwards after it emerges from the cracks, thus achieving a secondary water-blocking effect. The inward-sloping opening of the grinding groove makes it difficult for the concrete to come out of the grinding groove after it has hardened, preventing the steel plate from floating and ensuring that the waterproof coating always adheres to the bottom of the grinding groove, thereby improving the water-retaining effect. The support shaft supports the left and right sides of the grinding groove, further preventing the steel plate from floating.

[0007] Furthermore, the waterproof structure also includes a guide sleeve, which is fixedly connected to the upper side of the steel plate, and a support shaft passes through the guide sleeve and is slidably connected to the guide sleeve.

[0008] The above settings improve the stability of the support shaft movement.

[0009] Furthermore, the elastic element includes a movable plate, a fixed plate, and a spring. The movable plate is fixedly connected to the inner end of the support shaft, the fixed plate is located on the side of the movable plate away from the support shaft, and the spring is installed between the fixed plate and the movable plate.

[0010] Furthermore, the elastic element also includes a guide shaft, which is parallel to the support shaft. One end of the guide shaft is fixedly connected to the movable plate, the guide shaft passes through the fixed plate, and is slidably connected to the fixed plate. A spring is sleeved on the guide shaft.

[0011] With the above configuration, the guide shaft can support the spring and prevent the spring from bending.

[0012] Furthermore, a first slot is provided on the steel plate, and a second slot is provided at the end of the guide shaft away from the movable plate. The waterproof structure also includes a pin, and the support shaft also has an inward retraction state. In the inward retraction state, when the pin is inserted into the first slot through the second slot, the outer end of the support shaft is flush with the edge of the steel plate.

[0013] The above settings make it easy to load the steel plate into the grinding groove.

[0014] Furthermore, the included angle between the left and right sides of the grinding groove and the bottom of the groove is α, which is 60°. <a<80°。

[0015] Furthermore, the lateral width of the grinding groove is w1, and the lateral width of the steel plate is w2, where w1 > w2, and w1 > w2, 10mm. <w1-w2<20mm。

[0016] The above settings make it easy to place the steel plate into the grinding groove. Attached Figure Description

[0021] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0022] like Figures 1 to 4A waterproof structure for a basement floor slab is provided for sealing cracks 4 on the floor slab 3. A grinding groove is provided on the upper side of the crack 4 on the floor slab 3. The upper ends of the groove walls on both sides of the grinding groove are inclined inward. The waterproof structure includes resin 5, steel plate 6, waterproof coating 7, support shaft 8 and elastic element 9. Resin 5 fills the crack 4. The steel plate 6 is attached to the bottom of the grinding groove through the waterproof coating 7. The support shaft 8 is slidably connected to the upper sides of the left and right ends of the steel plate 6. The elastic element 9 applies elastic force to the support shaft 8. The support shaft 8 is in a supported state. In the supported state, the ends of the support shaft 8 at the left and right ends of the steel plate 6 are respectively supported on the groove walls on the left and right sides of the grinding groove. Concrete 10 is poured on the upper side of the steel plate 6.

[0023] With the above setup, resin 5 acts as a water-blocking agent, and waterproof coating 7 acts as a water-blocking agent, preventing water from continuing to seep upwards after it comes out of crack 4, thus achieving a secondary water-blocking effect. The groove opening of the grinding groove is narrowed inwards, making it difficult for concrete 10 to come out of the grinding groove after it has cured, preventing steel plate 6 from floating up, ensuring that waterproof coating 7 is always adhered to the bottom of the grinding groove, and improving the water-blocking effect. Support shaft 8 supports the left and right sides of the grinding groove, further preventing steel plate 6 from floating up.

[0024] During construction, a rectangular grinding groove with a horizontal bottom is first ground out at crack 4 using a grinder. The left and right sides of the grinding groove are then cut using a cutting machine to form inclined groove walls on both sides. Resin 5 is pressed into crack 4. After the resin 5 has cured, the steel plate 6 is bonded to the bottom of the groove through a waterproof coating 7. The steel plate 6 is fitted to the grinding groove and is rectangular. Two support shafts 8 are set on both sides of the steel plate 6. The support shafts 8 extend in the left and right directions. Under the action of the elastic element 9, the left support shaft 8 moves to the left and the left end abuts against the left side of the grinding groove. The right support shaft 8 moves to the right and the right end abuts against the right side of the grinding groove. The support shafts 8 are in a supported state. Concrete 10 is poured on the upper side of the steel plate 6. The upper side of the concrete 10 is flush with the upper side of the steel plate 6. After the concrete 10 has solidified, it prevents the support shafts 8 from moving left and right and also prevents the steel plate 6 from floating.

[0025] As one implementation method, the waterproof structure also includes a guide sleeve 11, which is fixedly connected to the upper side of the steel plate 6, and the support shaft 8 passes through the guide sleeve 11 and is slidably connected to the guide sleeve 11.

[0026] The above settings improve the stability of the movement of the support shaft 8.

[0027] The guide sleeve 11 of this application is basically a circular tube structure. The lower side of the guide sleeve 11 is welded to the steel plate 6. The support shaft 8 is slidably connected to the guide sleeve 11 on the same axis. The outer wall of the support shaft 8 is in contact with the inner wall of the guide sleeve 11, so that the support shaft 8 can move axially in a stable manner.

[0028] As an implementation, the elastic member 9 includes a movable plate 91, a fixed plate 92 and a spring 93. The movable plate 91 is fixedly connected to the inner end of the support shaft 8. The fixed plate 92 is arranged on the side of the movable plate 91 away from the support shaft 8. The spring 93 is installed between the fixed plate 92 and the movable plate 91.

[0029] In the present application, the movable plate 91 of the present application is vertically and fixedly connected to the inner end of the support shaft 8. The fixed plate 92 and the movable plate 91 have substantially the same shape, are arranged inside the movable plate 91, and are fixedly connected to the steel plate 6. The spring 93 is in a compressed state and is installed between the fixed plate 92 and the movable plate 91, and provides an elastic force to the support shaft 8 through the movable plate 91.

[0030] As an implementation, the elastic member 9 further includes a guide shaft 94. The guide shaft 94 is parallel to the support shaft 8. One end of the guide shaft 94 is fixedly connected to the movable plate 91. The guide shaft 94 passes through the fixed plate 92 and is slidably connected to the fixed plate 92. The spring 93 is sleeved on the guide shaft 94.

[0031] Through the above settings, the guide shaft 94 can support the spring 93 and prevent the spring 93 from bending.

[0032] As an implementation, a first slot 12 is provided on the steel plate 6. A second slot 13 is provided at one end of the guide shaft 94 away from the movable plate 91. The waterproof structure further includes a pin 95. The support shaft 8 further has a retracted state. In the retracted state, when the pin 95 passes through the second slot 13 and is inserted into the first slot 12, the outer end of the support shaft 8 is flush with the edge of the steel plate 6.

[0033] Through the above settings, it is convenient to install the steel plate 6 into the grinding groove.

[0034] Specifically, before the steel plate 6 is installed into the grinding groove, the pin 95 passes through the second slot 13 and is inserted into the first slot 12, as Figure 4 , the support shaft 8 is in a retracted state, which is convenient to put the steel plate 6 into the grinding groove. After the lower side of the steel plate 6 is bonded to the bottom of the groove through the waterproof coating 7, the pin 95 is pulled out upward, the spring 93 extends, the support shaft 8 moves outward, and the end of the support shaft 8 automatically abuts against the groove wall of the grinding groove.

[0035] As an implementation, the included angle between the groove walls on the left and right sides of the grinding groove and the bottom of the groove is a, 60° < a < 80°.

[0036] In the present application, the larger the included angle between the groove wall and the bottom of the groove, the closer the groove wall is to the vertical plane, the smaller the frictional force between the support shaft 8 and the groove wall, and the worse the effect of resisting the floating of the steel plate 6. The smaller the included angle, the more inclined the groove wall. Although the effect of resisting the floating of the steel plate 6 is better, the space between the groove wall and the bottom of the groove is smaller, and it is more difficult to pour the concrete 10; when 60° < a < 80°, the convenience of pouring the concrete 10 and the anti-floating effect are taken into account.

[0037] As one implementation method, the lateral width of the grinding groove is w1, and the lateral width of the steel plate 6 is w2, where w1 > w2, and w1 > w2, 10mm. <w1-w2<20mm。

[0038] The above settings make it easy to place the steel plate 6 into the grinding groove.

[0039] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
