Description

Technical Field

[0001] The present invention relates to the technical field of basement settlement waterproofing, and in particular to a basement settlement joint waterproofing structure and a construction method. Background Art

[0002] Settlement joints are vertical joints designed to prevent damage to a building due to uneven foundation settlement. When adjacent parts of a building differ significantly in height, load, and structural form, and the foundation is weak, the building may experience uneven settlement, causing cracks in certain weak areas. To this end, settlement joints should be installed at appropriate locations, such as at complex planes or transitions, at height changes, and where there are significant differences in load, foundation compressibility, or foundation treatment methods. When leakage occurs in a settlement joint, water can seep into the building through the joint, causing internal seepage. Long-term seepage can also lead to corrosion of the internal structure, so waterproofing measures are generally required for settlement joints.

[0003] Waterproofing generally falls into two categories: flexible waterproofing, such as waterstops and waterstop strips, and rigid waterproofing, such as waterproof mortar and waterstop steel plates. Existing settlement joints are typically waterproofed with waterstops. The sidewalls of the waterstop are glued to the inner wall of the settlement joint to seal the joint and act as a barrier. However, these waterstops are difficult to remove after installation, making leaks difficult to remedy. When used, water flowing into the settlement joint will settle on the waterstop, making it difficult to penetrate the joint and enter the ground. These solutions, due to long-term settlement, deformation, and aging, are bound to cause seepage and leakage over a period of several years. Furthermore, waterstops typically only provide waterproofing, but are inconvenient for diverting and draining water.

[0004] Therefore, the current waterproofing measures for basement settlement joint waterproofing structures still have many deficiencies, and the waterproofing structure is still unsatisfactory. In view of the defects of existing waterproofing structures and methods, it is necessary to explore new basement settlement joint waterproofing structures and construction methods to meet the needs of building construction, so as to achieve good waterproofing effects and simple construction operations. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that water flow deposited on the waterstop easily causes aging and water seepage, and it is inconvenient to replace the waterstop after it is damaged.

[0006] To solve the above technical problems, the present invention provides a technical solution: a basement settlement joint waterproof structure, comprising a buried rubber waterstop located between two basement exterior walls and a detachable rubber waterstop located between the two basement exterior walls and behind the buried rubber waterstop, wherein the lower end of the buried rubber waterstop is inclined and connected to a detachable base;

[0007] The lower end of the embedded rubber waterstop is provided with a connecting block, the area of the connecting block is smaller than the area of the embedded rubber waterstop, the base is sleeved on the outside of the connecting block, and the area is larger than the area of the embedded rubber waterstop, and the side wall of the base is plugged with a limiting rod passing through the connecting block;

[0008] The outer cover of the limit rod is connected to a rubber ring connected to the base;

[0009] The lower end of the base is connected to a Chinese-shaped plate, and the lower end of the Chinese-shaped plate is horizontal;

[0010] The middle part of the cross-section of the buried rubber waterstop is a circular ring, and the two ends are trapezoidal with the long bottom surface located on the outside, with a well-shaped structure in between. The middle part and the two ends of the cross-section of the detachable rubber waterstop are elliptical, and are connected by a rectangle with a width less than the radius of the ellipse. A groove matching the cross-sectional shape is provided on the top of the detachable rubber waterstop.

[0011] The construction method of the basement settlement joint waterproof structure comprises the following steps:

[0012] Step 1: Select the corresponding length of embedded rubber waterstop and detachable rubber waterstop according to the design requirements of the project;

[0013] Step 2: Connect the embedded rubber waterstop to the base, and insert the limit rod between the base and the connecting block to fix it;

[0014] Step 3: Place the base on the concrete, tilt it downwards towards the side away from the basement, and fix it by pouring concrete in its U-shaped plate, so that the embedded rubber waterstop is in a vertical state, and the detachable rubber waterstop is located at the back and in a vertical state, and then pour concrete on top in sequence, leaving settlement joints between them;

[0015] Step 4: Fill the settlement joint between the embedded rubber waterstop and the detachable rubber waterstop with caulking material to achieve waterproofing.

[0016] The present invention has the following advantages:

[0017] 1. Compared with the waterstop in the existing technology that will accumulate water, the bottom of the buried rubber waterstop is tilted, and the connected base is tilted, which can prevent water from accumulating on the waterstop and instead drain it into the ground, avoiding erosion of the waterstop;

[0018] 2. A detachable rubber waterstop is provided on the rear side of the buried rubber waterstop to further waterproof the water, so that the buried rubber waterstop can still play a protective role even if it is damaged;

[0019] 3. The detachable rubber waterstop is replaceable and can be used continuously when the buried rubber waterstop leaks only in a small area, making replacement more convenient.

[0020] 4. The construction of buried rubber waterstop and detachable rubber waterstop is simple. It is achieved by first pouring the base and then keeping the buried rubber waterstop in a vertical state. The detachable rubber waterstop is located at the back and in a vertical state, and then pouring concrete on top. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention is further described in detail below with reference to the embodiments.

[0029] Example 1, combined with the attached Figure 1-6

[0030] A basement settlement joint waterproofing structure comprises a buried rubber waterstop 1 located between two basement outer walls and a detachable rubber waterstop 2 located between the two basement outer walls and at the rear side of the buried rubber waterstop 1. The lower end of the buried rubber waterstop 1 is inclined and is connected to a detachable base 3.

[0031] Through the above structure, the bottom of the buried rubber waterstop 1 is tilted, which can prevent water from accumulating on the waterstop, but drain it into the ground. Combined with the detachable rubber waterstop 2, double waterproofing is achieved, with good waterproof effect.

[0032] The middle part of the cross-section of the buried rubber waterstop 1 is a circular ring, and the two ends are trapezoidal with the long bottom surface located on the outside, with a well-shaped structure in between. The middle part and the two ends of the cross-section of the detachable rubber waterstop 2 are elliptical, and are connected by a rectangle with a width less than the radius of the ellipse. A groove 8 matching the cross-sectional shape is provided above the detachable rubber waterstop 2.

[0033] Through the above structure, the buried rubber waterstop 1 and the detachable rubber waterstop 2 will not be offset in the wall, and the rubber shape can be deformed without cracking when the basement settles differently. The detachable rubber waterstop 2 can be pulled out of the concrete and replaced by reducing its volume after the air is extracted. When the buried rubber waterstop 1 only leaks in a small area, it can be continuously replaced and used, making replacement more convenient.

[0034] The lower end of the embedded rubber waterstop 1 is provided with a connecting block 4, the area of the connecting block 4 is smaller than the area of the embedded rubber waterstop 1, the base 3 is sleeved on the outside of the connecting block 4, and the area is larger than the area of the embedded rubber waterstop 1, and the side wall of the base 3 is plugged with a limiting rod 5 passing through the connecting block 4; the outer surface of the limiting rod 5 is connected to a rubber ring 6 connected to the base 3; the lower end of the base 3 is connected to a Chinese-shaped plate 7, and the lower end of the Chinese-shaped plate 7 is horizontal.

[0035] Through the above structure, the base 3 and the connecting block 4 are connected to the lower end of the buried rubber waterstop 1, so that water will not penetrate from the connection gap, and the waterproof effect is better. The base 3 and the connecting block 4 are connected by a limiting rod 5, so that the connection between the two is convenient and firm. At the same time, the earth-shaped plate 7 below facilitates the pouring of concrete to fix the position of the base 3.

[0036] The construction method of the basement settlement joint waterproof structure comprises the following steps:

[0037] Step 1: Select the embedded rubber waterstop 1 and the detachable rubber waterstop 2 of corresponding length according to the design requirements of the project;

[0038] Step 2: Connect the embedded rubber waterstop 1 to the base 3, and insert the limit rod 5 between the base 3 and the connecting block 4 to fix them;

[0039] Step 3: Place the base 3 on the concrete first, tilt it downward toward the side away from the interior of the basement, and fix it by pouring concrete in its earth-shaped plate 7, so that the buried rubber waterstop 1 is in a vertical state, and the detachable rubber waterstop 2 is located at the rear side and in a vertical state, and pour concrete on top in sequence, leaving a settlement joint between them;

[0040] Step 4: Fill the settlement joint between the embedded rubber waterstop 1 and the detachable rubber waterstop 2 with caulking material to achieve waterproofing.

[0041] When the present invention is implemented, the bottom of the buried rubber waterstop 1 is tilted, and the connected base 3 is tilted, so that water will not accumulate on the waterstop, but will be discharged into the ground. The detachable rubber waterstop 2 is arranged on the rear side of the buried rubber waterstop 1 to further waterproof the water, so that the buried rubber waterstop 1 can play a protective role after being damaged. The detachable rubber waterstop 2 can be pulled out of the concrete and replaced by reducing the volume after the air therein is extracted. When the buried rubber waterstop 1 only leaks in a small range, it can be continuously replaced and used, and replacement is more convenient.

[0042] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications and improvements may be made based on the present invention. Therefore, such modifications and improvements, which do not depart from the spirit of the present invention, are intended to be within the scope of protection claimed herein.
