Description

Technical Field

[0001] The utility model relates to the technical field of water tanks, in particular to an assembled prefabricated high-strength anti-seepage reinforced concrete module and a concrete steel structure water tank. Background Art

[0002] Integral cast-in-place concrete water tanks, carbon steel plate welded water tanks, FRP water tanks, BDF composite water tanks and stainless steel flat plate welded water tanks are some of the most commonly used water tanks in existing construction projects. However, the above water storage containers all have some disadvantages: 1. Integral cast-in-place concrete water tanks have a long construction period, require a lot of labor, and have very high requirements for construction technology and techniques. In addition, human factors have a great impact on the quality during the pouring process. For example, problems such as water seepage and leakage are difficult to repair. 2. Carbon steel plate welding has very high technical requirements for welders, and the density of the weld is not easy to control. It is easy to rust, resulting in a short life of the water tank, affecting the service life of the equipment. The rusty water and yellow water will breed bacteria and cause secondary pollution of the water body. 3. The FRP water tank is a kind of industrial-grade resin material combined with glass fiber synthesis. The product is made of stainless steel and steel plates, with low overall compressive bearing capacity. It is easy to deform when the volume is too large, and the sand-included process causes water leakage. The material itself is difficult to degrade and pollutes the environment. 4. BDF composite water tank, which is made of stainless steel and steel plates. It has low positive pressure and lateral pressure bearing capacity. The support of the grid structure has a small support force surface. As the material ages, there is a risk of collapse. 5. Stainless steel flat plate welded water tank, the raw materials are affected by the prices of nickel and chromium, the cost is high, and the workers' construction technology level is very high. The welding points are prone to leakage and rust. The water containing salt and chlorine is easy to fall off at the welding points, causing the overall collapse of the water tank.

[0003] At present, the replacement product of the above-mentioned water tank is the commercial concrete plate assembled water tank. The commercial concrete plate assembled water tank is generally made of concrete plates. The water tank is mainly composed of steel bars, concrete, and steel pipes. The interior is supported by a grid-type steel pipe. The prefabricated product is formed by setting U-shaped steel between adjacent composite plates, and then pulling them together and then grouting them for the second time.

[0004] However, in the process of assembling the commercial concrete panels into concrete water tanks, there are the main panels' tension connection and secondary grouting processes, which are complicated and inefficient to construct. The secondary grouting of the joints is difficult to be completely dense and the joints with the original panels are prone to cracking, resulting in leakage. When used as a wastewater pool, the leaked wastewater can easily pollute the surrounding soil and surface water sources. Moreover, the grid structure has low seismic strength and does not meet the design requirements of some areas that require a seismic resistance of no less than 6.8. The grid structure commercial concrete slab water tank cannot be built under fire passages and parking spaces. Due to the location of the space, it has to be built under fire passages and parking spaces, and structural columns and top plates are required, which increases construction costs. Utility Model Content

[0005] Based on the above technical problems, the present application provides an assembled prefabricated reinforced concrete module and a concrete steel structure water tank, which adopts a set of prefabricated modules in the factory and is assembled as a whole on the construction site. The construction process is simple, the construction efficiency is high, the construction is easy on site, and no technical workers are required for construction.

[0006] In a first aspect, the present application provides an assembled prefabricated high-strength and anti-seepage reinforced concrete module, which adopts the following technical solution:

[0007] An assembled prefabricated high-strength and waterproof reinforced concrete module includes a module body, wherein the module body includes a prefabricated panel and a frame connector integrally formed with the prefabricated panel, wherein the frame connector is bent laterally along the prefabricated panel and is provided with a connection hole, and a clamping member is passed through the connection hole to clamp the frame connector so that the panels are fixedly connected.

[0008] By adopting the above-mentioned technical scheme, the frame connector of the present application is integrally formed with the prefabricated panel, that is, the prefabrication process in the factory is increased, the assembly process at the construction site is simplified, and the frame connector is directly clamped by the clamping parts, thereby avoiding process steps such as secondary grouting, and facilitating prefabricated installation, while greatly shortening the on-site assembly time; in addition, because the secondary grouting process is reduced, the overall performance of the one-time assembly is better, the anti-leakage ability is stronger, the plate assembly has greater flexibility, and the high-strength and anti-seepage reinforced concrete module has a stronger resistance to positive pressure and lateral pressure.

[0009] In some specific possible implementation schemes, the frame connector is a flange plate, and the frame connectors on adjacent prefabricated panels are parallel to each other.

[0010] By adopting the above technical solution, the frame connector is limited to a flange plate, which is more convenient for installation and construction than the prior art that uses additional U-shaped steel for fixed connection and secondary pouring. Therefore, for a water reservoir of the same volume, labor can be saved to the greatest extent and potential safety hazards during construction can be reduced. In addition, the flange plate is arranged to protrude along the side of the prefabricated plate, and the angle between the frame connector and the prefabricated plate is not specifically limited, which increases the yield of the frame connector and can be applied to different application requirements.

[0011] In some specific implementation schemes, the frame connector is arranged at an angle of 85-95° to the prefabricated panel.

[0012] By adopting the above technical solution, a certain angle can be formed between the frame connector and the prefabricated panel, but parallel lines are formed between adjacent frame connectors. If the angle is too large, stress concentration bending is likely to occur when the two sides are pulled together, resulting in breakage and other adverse conditions.

[0013] In some specific implementation schemes, the frame connector is arranged at 90° to the prefabricated panel.

[0014] By adopting the above technical solution, a 90° angle is preferably formed between the frame connector and the prefabricated panel, which facilitates tightening the clamping member and helps to improve the regularity and stability of the two adjacent prefabricated panels after alignment.

[0015] In some specific implementation schemes, the clamping member is a high-strength bolt and nut splicing assembly made of hot-dip galvanized material.

[0016] By adopting the above technical solution, in order to tighten the 90° angle, the present application matches a high-strength bolt and nut splicing assembly made of hot-dip galvanized material, which helps to improve the corrosion resistance of the bolts and nuts and prevent the water tank from rusting after a period of use.

[0017] In some specific possible implementation schemes, a high-strength, corrosion-resistant, and aging-resistant sealing and waterproof rubber strip is filled between two frame connectors connected to adjacent prefabricated panels.

[0018] By adopting the above technical solution, the splicing of the water tank main body enclosure panels is changed from a fully rigid combination to a flexible combination, which makes the connection between the panels tighter and the anti-penetration performance of the joints better, and more effectively improves the anti-penetration performance of the concrete steel structure water tank composed of this type of product.

[0019] In a second aspect, the present application provides a concrete steel structure water tank assembled using the above-mentioned high-strength anti-seepage reinforced concrete modules, comprising:

[0020] High-strength, impermeable reinforced concrete modules are used to enclose and form the main body of the water tank;

[0021] Steel columns are used to support the interior of the concrete module, and the steel columns are connected to the embedded parts in the cast-in-place base plate;

[0022] A steel beam, used to bear load pressure, wherein the steel beam is connected to the steel column and the side wall of the concrete module;

[0023] The top plate, the steel beams and steel columns are assembled into a supporting frame, the top plate is covered on the supporting frame, the top plate is a high-strength anti-seepage reinforced concrete module, the long side of the top plate module is inclined at a certain angle, and there is no flange plate, which is convenient for the top plate surface to be connected and the seam processing.

[0024] By adopting the above technical scheme, the main body of the assembled high-strength and anti-seepage reinforced concrete water tank is assembled by adopting the high-strength and anti-seepage reinforced concrete modules of the present application. The various parts are easy to connect and the on-site assembly speed is significantly improved. At the same time, through the cooperation between the steel columns and the steel beams, compared with the galvanized pipes (galvanized pipes with stainless steel sleeves) in the prior art, it helps to improve the compressive strength, seismic strength and overall stability of the water tank.

[0025] In some specific possible implementation schemes, the steel columns are connected to the embedded parts in the cast-in-place base plate through studs; and the steel beams are connected to the steel columns through welding or studs.

[0026] By adopting the above technical solution, the connection between the steel column and the cast-in-place base plate, and between the steel beam and the steel column is simple and efficient, which improves the assembly efficiency at the construction site and saves a lot of labor.

[0027] In some specific implementation schemes, the distribution density of the steel columns is 10-18m 2 / pieces, and the distribution density of the steel beams is 4-6m / track.

[0028] By adopting the above technical solution, the interior of the water tank of the present application is more spacious, which is convenient for later repair and maintenance; at the same time, the steel columns and steel beams themselves have higher compressive strength and seismic resistance level. Compared with the high-density distribution of galvanized pipes in the prior art, the sparse distribution of the present application can also achieve better compression and seismic resistance effects; in addition, the sparse distribution can also improve the construction safety and construction efficiency of the assembly site;

[0029] In summary, the utility model has at least one of the following technical effects:

[0030] 1. It simplifies the assembly process at the construction site, saves the process steps such as secondary grouting, and is formed in one step, which is more convenient for prefabricated installation and greatly shortens the assembly time on site;

[0031] 2. Compared with the separate U-shaped steel and secondary grouting technology in the prior art, the flange-shaped integrated frame connector is more convenient to install, has better overall performance and sealing performance, can greatly reduce labor, save construction time, and improve work efficiency;

[0032] 3. Compared with the existing grid support system, the assembled high-strength and anti-seepage reinforced concrete water tank of this application has a more spacious internal space and is easier to clean and maintain; and the distribution spacing between the steel columns and the steel beams is large, which improves the construction safety of the assembly site;

[0033] 4. The assembled high-strength and impermeable reinforced concrete water tank of the present application has high compressive resistance. For sites with small footprint, it can be built in parking lots and fire passages, and has greater flexibility;

[0034] 5. The assembled high-strength and anti-seepage reinforced concrete water tank of the present application has stronger corrosion resistance and a wide range of uses. It can be applied to various types of water storage tanks such as rainwater collection tanks, fire protection tanks, regulating tanks, ecological filter tanks, septic tanks, grease traps, sewage collection and treatment tanks, emergency tanks, etc. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that the various aspects, features, implementation methods and advantages described in the present application can be compatible and / or can be combined together.

[0042] Example 1

[0043] This embodiment relates to an assembled prefabricated high-strength anti-seepage reinforced concrete module. Figure 1-2 , including a module body 1, which can be installed on the cast-in-place bottom surface. A pre-buried groove is reserved on the cast-in-place bottom surface, and the bottom end of the module body 1 is installed in the pre-buried groove to ensure the regularity of the construction effect; the module body 1 includes a prefabricated panel 2 and a frame connector 3 integrally formed with the prefabricated panel 2, and the frame connectors 3 on adjacent prefabricated panels 2 are connected by clamping members 5.

[0044] refer to Figure 1 The precast panel 2 is a high-strength and impermeable reinforced concrete precast panel 2. The internal steel bars constitute the skeleton part of the precast panel 2. The shear resistance and bending resistance of the precast panel 2 depend on the content and arrangement of the steel bars in the precast panel 2. Concrete is the main part of the precast panel 2 and is also the main receptor for the compression of the precast panel 2. The compressive strength of the precast panel 2 itself is related to the strength grade of the concrete used. Considering that it is mainly used in the storage of various water bodies, this embodiment uses impermeable high-strength concrete.

[0045] refer to Figure 1-2In this embodiment, the frame connector 3 is a flange plate, which is connected to the steel bars in the prefabricated panel as a whole. The plane where the frame connector 3 is located is perpendicular to the plane where the prefabricated panel 2 is located or there is an angle of 85-95°. If there is an angle of 85-95° between the two, the two flange plates are connected by screws between the frame connector 3 and the prefabricated panel 2. In this embodiment, the angle formed by the two is preferably 90°, which helps to facilitate the alignment and clamping of adjacent prefabricated panels 2.

[0046] refer to Figure 1-2 As shown, the clamping member 5 includes a bolt and nut made of hot-dip galvanized material, which is not easy to rust. A plurality of connection holes 4 are provided on the flange plate along its own length direction. The number of connection holes 4 is determined according to the anti-seepage requirements. In this embodiment, 6 holes are arranged. The bolts pass through the connection holes 4, and then the nuts are threadedly connected with the bolts to clamp the two adjacent flange plates, thereby aligning the two adjacent prefabricated panels 2. In addition, before the bolts and nuts are threadedly connected, a high-strength and corrosion-resistant sealing strip 6 can be filled between the two frame connectors 3 connected on the adjacent prefabricated panels 2, which helps to improve the waterproof and anti-seepage performance of the water tank.

[0047] After the precast panel 2 is formed, a layer of corrosion-resistant anti-seepage membrane is precast on the surface of the precast panel 2 to further improve the corrosion resistance and anti-seepage properties of the high-strength anti-seepage reinforced concrete module.

[0048] In order to facilitate the lifting and transportation of the high-strength anti-seepage reinforced concrete module, during the prefabrication process of the prefabricated panel 2, a lifting ring is added to the prefabricated panel 2 and connected to the main steel bars inside the module for easy lifting, so that the prefabricated panel 2 can be lifted conveniently.

The steel beam 8 and the steel column 7 are assembled into a support frame, and the top plate is laid on the support frame. The steel column 7 is fixed to the embedded part in the cast-in-place bottom plate by bolt connection, and the steel beam 8 and the steel column 7 are connected or welded by studs in this embodiment.

The distribution density of the steel columns 7 can be 10-18m 2 / pcs, the distribution density of the steel beams 8 can be 4-6m / track. In this embodiment, the distribution density of the steel columns 7 is preferably 12m2 / piece, the distribution density of the steel beam 8 is preferably 5m / track. In the prior art, galvanized pipes are used as supporting beams, and the distribution density of galvanized pipes is relatively large, and the compression resistance effect is not as good as the steel beam 8 and the steel column 7 in this embodiment.

[0052] A fully automatic water tank self-cleaning device can also be installed in the concrete steel structure water tank in this embodiment to automatically flush the water tank regularly; and a water tank flow guider can be installed to prevent insufficient flow during the water pumping process.
