Technical Field

[0001] This utility model relates to the field of steel plate waterstops, and in particular to a steel plate waterstop that can be installed on a waterproof sleeve for a water tank. Background Technology

[0002] Steel plate waterstop, also known as waterstop steel plate, is a waterproof building material commonly used in construction projects.

[0003] Most existing steel plate waterstops are single-piece plate structures that are integrally formed and cannot be lengthened. Furthermore, when additional structures are needed, welding is usually required, which makes them inconvenient to use during disassembly and assembly.

[0004] Therefore, since most of the existing plate structures are individually molded, it is inconvenient to add structures and make adjustments. A steel plate waterstop that can be installed with a waterproof sleeve for the water tank can be designed to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing steel plate waterstops, which are mostly individual plate structures and are integrally formed, and which require welding when adding other structures, resulting in inconvenience during disassembly and assembly, and the inability to change the length of the integral structure.

[0006] The technical solution of this utility model is as follows: a steel plate waterstop that can be installed with a waterproof sleeve for a water tank, comprising a hollow steel plate waterstop on the sides, a solid steel plate waterstop in the center, fixing rings, connecting shafts, a pressing friction belt, a tightening block, a hollow waterproof sleeve on the sides, a sliding groove, a slider, and a hollow waterproof sleeve in the center. A solid steel plate waterstop is provided between the hollow steel plate waterstops on the sides. Fixing rings are provided on both sides of the upper end of the hollow steel plate waterstops on the sides. A connecting shaft is provided on the fixing rings. A pressing friction belt is provided between the connecting shafts. A tightening block is provided on the pressing friction belt. A hollow waterproof sleeve on the sides is provided at the lower end of the pressing friction belt. The inner side of the water jacket is provided with a sliding groove, on which a slider is slidably connected. Inside the slider is a central hollow waterproof sleeve. The side hollow waterproof sleeve and the central hollow waterproof sleeve can be fixed to the side hollow steel plate waterstop and the central solid steel plate waterstop by a fixing ring, a connecting shaft, a pressing friction belt, and a tightening block, thus realizing the installation work. At the same time, the tightening block can be adjusted on the pressing friction belt to realize the tightening and loosening. It can fix waterproof sleeves of water tanks with different diameters. The slider can be moved into the side hollow waterproof sleeve, and the central solid steel plate waterstop can be moved into the side hollow steel plate waterstop, thus realizing the adjustment of the installation length for convenient use.

[0007] Preferably, the retractable plate and pipe structure facilitates adjustment and use, while the binding structure provides fixation.

[0008] Preferably, the side hollow steel plate waterstop and the central solid steel plate waterstop are configured as an open U-shape.

[0009] Preferably, two hollow steel plate waterstops are provided on the sides, respectively located at the front and rear ends, with a central solid steel plate waterstop slidably connected between them.

[0010] Preferably, the fixing ring is set at the upper end of the side hollow steel plate waterstop, and the connecting shaft is set on the fixing ring. The four fixing rings, two connecting shafts, one pressing friction belt and one tightening block are set as a group, and a total of four groups are set. Two groups are set on one side hollow steel plate waterstop, and one side hollow steel plate waterstop and two groups of four fixing rings, two connecting shafts, one pressing friction belt and one tightening block are set as a whole. A total of two wholes are set, and the two wholes are connected by the central solid steel plate waterstop.

[0011] Preferably, both the side hollow waterproof sleeve and the central hollow waterproof sleeve are designed as hollow cylinders.

[0012] Preferably, the inner side of the hollow waterproof sleeve is provided with four grooves, and each groove has a corresponding sliding block.

[0013] Preferably, a side hollow waterproof sleeve and four sliding grooves are configured as a whole, and a central hollow waterproof sleeve and eight sliders are configured as another whole, with the sliders sliding on the sliding grooves.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting a central solid steel plate waterstop, displacement can be achieved within the side hollow steel plate waterstops, enabling length adjustment. The side hollow steel plate waterstops are then externally fixed for easy use. Simultaneously, a connecting shaft connects to a fixing ring, and a tightening friction belt is used for retraction and extension via a tightening block. This facilitates the clamping and fixing of side hollow waterproof sleeves of different diameters, enabling installation. A slider slides within a groove, causing displacement of the central hollow waterproof sleeve, further adjusting its length for convenient adjustable use. This overcomes the shortcomings of existing steel plate waterstops, which are mostly single-piece plate structures, integrally molded, and often require welding when adding other structures, leading to inconvenience during assembly and disassembly, and the inability to adjust the length of the integral structure.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Among the currently discovered feasible technologies, steel plate waterstops, also known as waterstop steel plates, are a type of waterproof building material commonly used in construction projects. The following is a detailed introduction to them:

[0023] Material and Specifications

[0024] Material: Cold-rolled steel sheet is generally used as the base material because its uniform thickness makes it more suitable for making waterstops compared to hot-rolled steel sheet. In addition, there are waterstops made of galvanized steel sheet, stainless steel sheet, etc. Galvanized steel sheet waterstops can effectively change the water seepage path and enhance corrosion resistance, making them suitable for construction environments where leaking water may contain corrosive components; stainless steel sheet waterstops have better corrosion resistance and durability.

[0025] Specifications: Common thicknesses are 2mm and 3mm, widths are 200mm, 300mm, 350mm, 400mm, etc., and lengths are generally processed to be 3 meters or 6 meters long, with 3-meter lengths being more convenient for transportation.

[0026] Working principle

[0027] Steel plate waterstops are primarily used to address waterproofing issues at construction joints. In concrete structures such as box foundations or basements, the concrete for the base slab, exterior wall panels, and roof slab is typically poured separately. When the construction joint is located below the groundwater level, water seepage is likely to occur. Steel plate waterstops are pre-embedded during the pouring of the lower layer of concrete, with 10-15cm of the upper portion exposed. This exposed portion is then poured into the next layer of concrete, effectively cutting off the water seepage path. Even if water seeps along the gap between the waterstop plate and the concrete, the width of the steel plate extends the seepage path, preventing external pressurized water from penetrating.

[0028] Construction key points

[0029] Installation Location: Efforts should be made to ensure the waterstop steel plate is aligned with the centerline of the wall to guarantee its waterproofing effect. If the installation location is off-center, the concrete coverage on one side of the waterstop steel plate may be insufficient, affecting its waterproofing performance.

[0030] Welding requirements: The weld between the two steel plates must be full and double-sided, with an overlap of at least 20mm. The weld must be tight and leak-free to prevent water from seeping in. Additionally, when welding the supports for the waterstop steel plates, small reinforcing bars can be spot-welded to the main reinforcement bars, but care must be taken to avoid damaging the main reinforcement bars.

[0031] Corner treatment: Water-stop steel plates at wall corners can be treated by bending a whole steel plate, T-shaped welding, or L-shaped welding to ensure the waterproof effect at the corner.

[0032] Passing through column stirrups: When the waterstop steel plate passes through the column stirrups, the stirrups that pass through can be broken to make open stirrups, which are then welded to the steel plate.

[0033] Opening direction: The "opening" of the waterstop steel plate should face the water-facing side, that is, the direction with water. If there is water in both directions, the opening should face the direction with more water. This increases the difficulty for water to seep around the waterstop in the construction joint, thus better fulfilling its waterproofing function.

[0034] Scope of application

[0035] Steel plate waterstops are suitable for structures with groundwater, such as water tanks, basements, underground parking lots, and other water-bearing buildings, as well as for horizontal and vertical construction joints buried below the ground level. In water conservancy and hydropower projects, tunnels, subways, and other infrastructure construction, steel plate waterstops are also frequently used to prevent water seepage at construction joints with high anti-seepage requirements.

[0036] Difference from rubber waterstop

[0037] Material properties: Steel plate waterstops are metal waterstops with high strength and hardness, and are not easily deformed, but they are relatively less flexible; rubber waterstops are made of highly elastic rubber material, which can produce elastic deformation under construction loads, thus sealing tightly. They have good elasticity and flexibility and can adapt to a certain degree of deformation and vibration.

[0038] Applications: Generally, steel plate waterstops are more commonly used for horizontal construction joints, while rubber waterstops are more frequently used for vertical construction joints. In addition, rubber waterstops are also commonly used in areas with post-cast strips, as well as in areas with large settlement deformations such as construction joints, post-cast strips, settlement joints, and expansion joints in slab / wall structures.

[0039] Further research reveals the following information about a steel plate waterstop that can be installed on a waterproof sleeve for water tanks:

[0040] I. Product Overview

[0041] This special steel plate waterstop is specifically designed based on the traditional steel plate waterstop, so that it can be better used in conjunction with the waterproof sleeve of the water tank, and meet the dual needs of waterproofing and sleeve installation for special water-related building structures such as water tanks.

[0042] II. Structural Features

[0043] Pre-drilled mounting holes: These holes are pre-set on the steel plate to precisely match the outer diameter of the waterproof sleeve in the water tank, allowing the sleeve to pass accurately through the waterstop for installation. The edges of these holes are typically treated specially, such as by smoothing or rust prevention, to prevent scratching the sleeve during installation or causing potential leaks due to rough edges.

[0044] Reinforcing rib design: To withstand the weight of the waterproof sleeve and potential external forces (such as water pressure, operating forces during installation), reinforcing ribs are installed around the waterstop or near the installation holes. These ribs can be formed by welding additional steel strips, effectively enhancing the structural strength of the waterstop in these areas and ensuring it does not deform under stress during use, thus guaranteeing its waterproofing effect.

[0045] Integrated Waterstop Wing Ring: Some of these waterstops integrate the waterstop wing ring with the main body of the waterstop. The waterstop wing ring is located around the part where the sleeve passes through the waterstop. Its function is to further extend the water penetration path. When water attempts to penetrate along the gap between the sleeve and the waterstop, the waterstop wing ring can provide additional blocking effect, just like the waterstop principle of traditional waterstops, reducing the possibility of water seepage by increasing the penetration distance.

[0046] III. Material Selection

[0047] Steel plate material: Similar to ordinary steel plate waterstops, high-quality cold-rolled steel plates are often used as the base material to ensure uniform thickness and reliable strength. For water tank environments with high requirements for corrosion resistance, such as industrial water tanks containing chemicals, galvanized steel plates or stainless steel plates, which have better corrosion resistance, are also used.

[0048] Sealing materials: Appropriate sealing materials are used at the joints with the waterproof sleeve and at the seams of the waterstop itself (if any). Common examples include rubber sealing rings, which have good elasticity and sealing performance, and can fill any tiny gaps that may exist, preventing water from seeping in from these areas. Additionally, sealant or other materials are sometimes used for auxiliary sealing. Sealant can be applied to key joints after installation to further enhance the waterproofing effect.

[0049] IV. Key Points of Construction

[0050] Sleeve Installation and Coordination: When installing the waterproof sleeve for the water tank, ensure that the sleeve accurately passes through the pre-drilled holes in the waterstop. Care must be taken during installation to avoid damage to the waterstop due to excessive force, especially protecting the treatment layer at the edge of the holes and the waterstop's flanges.

[0051] Waterstop fixing: After the waterproof sleeve is installed, the steel plate waterstop must be properly fixed. Generally, it can be connected to the steel reinforcement structure or pool wall formwork by welding or using special fasteners to ensure that the waterstop will not shift during concrete pouring and to ensure that it is in the correct position to achieve the best waterproofing effect.

[0052] Sealing Inspection: After the installation of the sleeve and waterstop is completed, the sealing condition of each part should be carefully inspected. For rubber sealing rings, it should be confirmed that they are installed in place and that there is no twisting or damage. For areas where sealant is used, it should be checked that the sealant is applied evenly and that there are no missed areas or gaps that are not filled. If any problems are found, they should be dealt with in a timely manner.

[0053] V. Scope of Application

[0054] This type of steel plate waterstop, which can be used to install waterproof sleeves for water tanks, is mainly suitable for various types of water tank construction, including but not limited to domestic water tanks, fire water tanks, industrial cooling water tanks, and sewage treatment tanks. When waterproof sleeves (such as inlet / outlet pipe sleeves, overflow pipe sleeves, etc.) are required on the tank walls and bottom of these tanks, and a good waterproofing effect is required, it can play a unique advantage, effectively preventing water leakage from the construction joint between the sleeve and the tank wall.

[0055] Please see Figures 1-4This utility model provides an embodiment: a steel plate waterstop that can be installed with a waterproof sleeve for a water tank, comprising a hollow steel plate waterstop 1, a solid steel plate waterstop 2, fixing rings 3, connecting shafts 4, a pressing friction belt 5, a tightening block 6, a hollow waterproof sleeve 7, a sliding groove 8, a slider 9, and a hollow waterproof sleeve 10.

The side hollow waterproof sleeve 7 and the central hollow waterproof sleeve 10 can be fixed to the side hollow steel plate waterstop 1 and the central solid steel plate waterstop 2 via a fixing ring 3, a connecting shaft 4, a pressing friction belt 5, and a tightening block 6, thus completing the installation. Simultaneously, the tightening block 6 can be adjusted on the pressing friction belt 5 to achieve retraction and expansion, allowing for the fixing of waterproof sleeves for water tanks of different diameters. The slider 9 can move into the side hollow waterproof sleeve 7, and the central solid steel plate waterstop 2 can move into the side hollow steel plate waterstop 1, allowing for adjustment of the installation length for ease of use. The side hollow steel plate waterstop 1 and the central solid steel plate waterstop 2 are designed with an open U-shape. There are two side hollow steel plate waterstops 1, located at the front and rear ends respectively, with the central solid steel plate waterstop 2 slidably connected between them. The fixing ring 3 is located at the upper end of the side hollow steel plate waterstop 1, and the connecting shaft 4 is located on the fixing ring 3.

One side hollow waterproof sleeve 7 and four sliding grooves 8 are set as a whole, and one central hollow waterproof sleeve 10 and eight sliders 9 are set as another whole, with the sliders 9 sliding on the sliding grooves 8.

[0056] During operation, the central solid steel plate waterstop 2 can be displaced within the side hollow steel plate waterstop 1 to achieve length adjustment. The side hollow steel plate waterstop 1 is then fixed externally for easy use. Simultaneously, the connecting shaft 4 connects to the fixing ring 3, and the pressure friction belt 5 is tightened and released via the tightening block 6, facilitating the clamping and fixing of side hollow waterproof sleeves 7 of different diameters for installation. The slider 9 slides within the slide groove 8, which can drive the central hollow waterproof sleeve 10 to move, achieving length adjustment for adjustable use, thus completing all the work.

[0057] Through the above steps, the central solid steel plate waterstop 2 can be displaced within the side hollow steel plate waterstop 1, achieving length adjustment. The side hollow steel plate waterstop 1 is then externally fixed for easy use. Simultaneously, the connecting shaft 4 connects to the fixing ring 3, and the pressure friction belt 5 is tightened and released via the tightening block 6, facilitating the clamping and fixing of side hollow waterproof sleeves 7 of different diameters for installation. The slider 9 slides within the groove 8, causing the central hollow waterproof sleeve 10 to shift, achieving length adjustment for adjustable use. This overcomes the shortcomings of existing steel plate waterstops, which are mostly individual plate structures, integrally formed, and often require welding when adding other structures, leading to inconvenience during assembly and disassembly, and the inability to change the length of the integral structure.
