Description

Technical Field

[0001] This invention relates to the construction of a water storage tank, and more particularly to a method for assembling the entire water storage tank structure on-site using prefabricated materials. Background Technology

[0002] Currently, domestic fire protection projects mainly rely on traditional fire pump stations. These stations use concrete-lined water tanks, and the fire protection systems are assembled using a modular, piecemeal approach. Furthermore, the technical skill levels of construction and installation teams vary considerably. This leads to the following significant problems in practical implementation:

[0003] First, it occupies a large area. The large area is mainly reflected in the fire pump room. Traditional fire pump rooms are assembled on-site using individual equipment in a modular fashion, resulting in very poor product integration. Considering the limitations of later inspections, maintenance, and traditional civil construction techniques, fire pump rooms often occupy a relatively large area.

[0004] Second, the construction period is long. Traditional fire pump stations, whether for fire water tanks or fire pump rooms, use concrete masonry walls, requiring multiple processes such as excavation, foundation compaction, steel reinforcement binding, initial concrete pouring, concrete setting, secondary concrete pouring, and further setting. This results in a very long construction period. Furthermore, if affected by weather conditions (rain), temperature, or other environmental factors, the construction period will be further extended, and project progress cannot be guaranteed.

[0005] Third, high cost. Traditional concrete-lined water tanks are bulky and cumbersome due to technological requirements and thickness, resulting in higher costs. Furthermore, the large footprint mentioned earlier increases civil engineering costs, and the long construction period and rising labor costs further exacerbate the problem. Therefore, traditional fire pump stations are expensive.

[0006] Fourth, traditional concrete water tanks are prone to leaks and seepage. Even with waterproofing, they are highly susceptible to leaks and seepage if not regularly maintained and waterproofed. Regular waterproofing is costly, while neglecting it makes leaks and seepage extremely easy. Leaks and seepage in fire-fighting water tanks have a fundamental impact on the entire fire protection system, and maintenance is also inconvenient. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides a construction and building method for a prefabricated fire pump station water tank that can be assembled on-site. The fire pump station water tank constructed using this method has good sealing performance, is easy to install and maintain, and has a short construction period.

[0008] To achieve the above-mentioned objectives, the present invention provides a construction and building method for a prefabricated fire pump station water tank, comprising the following steps:

[0009] S1: At the location where the water tank 11 needs to be installed, pour concrete to form the valve base plate 1 of the required size, and pre-embed several pre-embedded anchor bolts 43;

[0010] S2: A flat, hollow, rectangular metal shell 14 is made according to the required size for each piece, and steel bars 12 are arranged horizontally and vertically inside the metal shell 14. Then, concrete 13 is poured in and allowed to solidify and stabilize to form the plate 11.

[0011] S3: Cut a T-shaped profile body 200 and an inner sealing pressure plate 25 to an appropriate length so as to form a slot 211 on the two sides of the T-shaped profile body 200 to accommodate the side 111 of the plate 11;

[0012] S4: An installation groove 100 is opened on the surface of the valve base plate 1 at the corresponding position of the side wall 5 of the water tank to be installed;

[0013] S5: Place the pre-embedded foundation plate 42 at the bottom of the mounting groove 100, and fix the pre-embedded foundation plate 42 to the pre-embedded anchor screw 43 with screws;

[0014] S6: Fix the bottom of the steel frame 21 to the embedded foundation plate 42;

[0015] S7: Fill the installation groove 100 with concrete and let it solidify;

[0016] S8: After the concrete in the mounting groove 100 has solidified, insert the plate 11 into the T-shaped profile body 200 between the two steel frames 21. The side 111 of the plate 11 is embedded in the slot 211, and external sealing gaskets 23 are respectively placed between the outer wall surface 149 and the two inner surfaces of the end plate 201 of the T-shaped profile body 200. Simultaneously, an inner sealing gasket 24 is placed between the inner surface of the inner sealing pressure plate 25 and the inner wall surface 142. The inner sealing pressure plate 25 is fixed to the inner wall surface 142 of the plate 11 by two fastening screws 28, and simultaneously fixed to the end plate 201 of the T-shaped profile body 200 by screws 26. Thus, the side wall 5 is installed.

[0017] S9: Apply a sealing layer 340 to the surface of the valve base plate 1 within the inner range of the side wall 5.

[0018] Furthermore, in step S6, the bottom of the steel frame 21 is first welded and fixed to the fixed plate 48, and then the fixed plate 48 is fixed to the embedded foundation plate 42 by fixing screws 41, wherein the fixing screws 41 pass through the fixing screw holes 420 on the embedded foundation plate 42.

[0019] Furthermore, the diameter of the fixing screw hole 420 is larger than the diameter of the fixing screw 41 so that the alignment of the fixing plate 48 and the embedded base plate 42 can be adjusted by the gap between the fixing screw hole 420 and the fixing screw 41.

[0020] Furthermore, the metal casing 14 adopts the shape of the plate 11 to be manufactured. An opening 140 for pouring concrete is provided on the outer wall surface 149. In addition to the opening 140, a sealing surface 141 of a certain length is provided on the outer wall surface 149 near the two sides 111. This length is equivalent to the horizontal depth of the groove 211, but is usually greater than this depth so that the outer sealing gasket 23 provided between the sealing surface 141 of the plate 11 and the inner surface of the groove 211 can form a stable seal.

[0021] Furthermore, the metal casing 14 is made of stainless steel.

[0022] The present invention provides a construction and building method for a prefabricated fire pump station water tank. By creating an installation groove 100 on the valve base plate 1 at the corresponding position of the side wall 5 of the water tank, and placing a pre-embedded foundation plate 42 at the bottom of the installation groove 100, the pre-embedded foundation plate 42 is fixed to the pre-embedded anchor screws 43. This not only improves construction accuracy but also significantly shortens the construction cycle and reduces construction costs. The product boasts high precision, fast construction cycle, strong load-bearing capacity, and anti-buoyancy and anti-vibration properties. Furthermore, the water tank's panels 11 form a double-sealed structure, providing excellent leak-proof performance. In particular, even if leakage occurs in special circumstances, the fire pump station water tank constructed using the method provided by the present invention only requires identifying the leakage point, loosening the fastening screws 28 and 26, opening the inner sealing pressure plate 25, and replacing the inner sealing gasket 24. This not only ensures sealing performance and extends service life but also facilitates easy replacement, installation, and maintenance. Attached Figure Description

[0027] The preferred embodiments of the invention are given below with reference to the accompanying drawings to illustrate the technical solution of the present invention in detail.

[0028] See Figures 1 to 4 The present invention provides a construction and building method for a prefabricated fire pump station water tank, comprising the following steps:

[0029] S1: At the location where the water tank 11 needs to be installed, pour concrete to form the valve base plate 1 of the required size, and pre-embed several anchor bolts 43;

[0030] S2: A flat, hollow, rectangular metal shell 14 is made according to the required size for each piece, and steel bars 12 are arranged horizontally and vertically inside the metal shell 14. Then, concrete 13 is poured inside and allowed to solidify and stabilize to form the plate 11.

[0031] S3: Cut a T-shaped profile body 200 and an inner sealing pressure plate 25 to an appropriate length so as to form a slot 211 on the two sides of the T-shaped profile body 200 to accommodate the side 111 of the plate 11;

[0032] S4: An installation groove 100 is opened on the surface of the valve base plate 1 at the corresponding position of the side wall 5 of the water tank to be installed;

[0033] S5: Place the pre-embedded foundation plate 42 at the bottom of the mounting groove 100, and fix the pre-embedded foundation plate 42 to the pre-embedded anchor screws 43 with screws.

[0034] S6: Secure the bottom of the steel frame 21;

[0035] S7: Then fill the mounting slot 100 with concrete and let it solidify.

[0036] S8: After the concrete in the installation groove 100 has solidified, insert the plate 11 into the T-shaped profile body 200 between the two steel frames 21, and respectively set the outer sealing gasket 23 between the outer wall surface 149 and the two inner surfaces of the end plate 201 of the T-shaped profile body 200. At the same time, set the inner sealing gasket 24 between the inner surface of the inner sealing pressure plate 25 and the inner wall surface 142, and fix the inner sealing pressure plate 25 to the inner wall surface 142 of the plate 11 with two fastening screws 28, and fix it to the end plate 201 of the T-shaped profile body 200 with screws 26. Thus, the side wall 5 is installed; and

[0037] S9: Apply a sealing layer 340 to the surface of the valve base plate 1 within the inner range of the side wall 5, where there is leakage or seepage at the bottom of the water tank.

[0038] In this embodiment, step S6 involves first welding the bottom of the steel frame 21 to the fixed plate 48, and then fixing the fixed plate 48 to the embedded base plate 42 using fixing screws 41 passing through fixing screw holes 420 on the embedded base plate 42. The fixing screws 41 pass through the fixing screw holes 420 on the embedded base plate 42. Furthermore, the diameter of the fixing screw hole 420 is larger than the diameter of the fixing screw 41 so that the alignment of the fixed plate 48 and the embedded base plate 42 is adjusted by the gap between the fixing screw hole 420 and the fixing screw 41 (see [link]). Figure 4 ).

[0039] In addition, in this embodiment, the metal shell 14 adopts the shape of the plate 11 to be manufactured. An opening 140 for filling concrete is provided on the outer wall surface 149. In addition to the opening 140, a sealing surface 141 of a certain length is provided on the outer wall surface 149 near the two sides 111. The length is equivalent to the horizontal depth of the slot 211, but is usually greater than the depth so that the outer sealing gasket 23 provided between the sealing surface 141 of the plate 11 and the inner surface of the slot 211 can form a stable seal.

[0040] Thus, see Figures 1 to 3 The water tank constructed by the method of the present invention has four side walls 5 installed on the valve base plate 1 located at the bottom. Each side wall 5 is composed of several equally spaced vertically arranged steel frames 21 and several plates 11. Each steel frame 21 has slots 211 on two sides to accommodate the side edges 111 of the plates 11. Each plate 11 is disposed between two steel frames 21, with its two side edges 111 respectively embedded into the opposing slots 211 of the two steel frames 21 for fixation. A sealing element is provided between the side edges 111 and the slots 211 to form a sealed connection. In this embodiment, the steel frame 21 is integrally formed into an I-shaped profile frame by a T-shaped profile body 200 and an inner sealing pressure plate 25. The T-shaped profile body 200 and the inner sealing pressure plate 25 can be fixed by screws 26. This structure facilitates the installation of a seal between the steel frame 21 and the plates 11 (described below). The pool can also be equipped with a cover 500 to ensure safety and prevent impurities or debris from falling in. The cover 500 can be made of metal materials such as stainless steel or aluminum alloy, or non-metallic materials such as plastic. The end plate 201 of the T-shaped profile body 200 is fixed to the T-shaped profile body 200 by the first fixing screw 22.

[0041] See also Figure 4In this embodiment, the bottom end 291 of the steel frame 21 can be directly fixed to the fixing plate 48 by welding or other methods. Then, the fixing plate 48 of the bottom end 291 of the steel frame 21 is fixed to the embedded foundation plate 42 by fixing screws 41. In this way, the bottom end 291 of the steel frame 21 of the present invention is fixed to the embedded foundation plate 42 and then embedded in the concrete of the valve bottom plate 1 for a certain length below it so as to be fixed to the valve bottom plate 1. The surface of the embedded foundation plate 42 is nearly parallel to the bottom surface, and the several embedded anchor screws 43 previously embedded in the valve bottom plate 1 are further embedded in the concrete of the valve bottom plate 1. This not only facilitates the subsequent fixing of the fixing plate 48 and the embedded foundation plate 42, but also further reinforces the embedded foundation plate 42 and the entire steel frame 21 after the installation groove 100 is poured with concrete and solidifies. This is one of the significant features of the present invention, which ensures the stability of the side wall 5 of the constructed water tank.

[0042] See Figure 1 , Figure 2 The slab 11 constructed in step S2 is made of SLRC material. Its main body consists of longitudinal and transverse reinforcing bars 12, concrete 13, and a hollow metal shell 14, which is formed by concrete pouring. In this embodiment, the metal shell 14 is made of stainless steel. Therefore, the slab 11 possesses the excellent load-bearing capacity, earthquake resistance, and fire resistance of reinforced concrete, while also having the corrosion resistance and impermeability of stainless steel. The inner wall surface 142 of the slab 11, which is in contact with water, is entirely made of stainless steel, making it less prone to microbial growth compared to traditional concrete. The metal shell 14 adopts the shape of the slab 11 to be manufactured, and has an opening 140 for pouring concrete on its outer wall surface 149. In addition to the opening 140, the outer wall surface 149 also has a sealing surface 141 of a certain length near the two sides 111. This length is comparable to the horizontal depth of the slot 211, but is typically greater than this depth so that the outer sealing gasket 23 disposed between the sealing surface 141 of the plate 11 and the inner surface of the slot 211 can form a stable seal (see...). Figure 3 Therefore, it can be seen that setting an opening 140 on the outer wall surface 149 of the metal shell 14 ensures the convenience of concrete pouring and the quality of concrete pouring, while not affecting the installation of the outer sealing gasket 23 or the strength of the entire plate 11, which is a unique technical solution.

[0043] Based on the above description, the construction and building method of the prefabricated fire pump station water tank provided by the present invention not only improves the construction accuracy but also greatly shortens the construction cycle and reduces the construction cost. This method involves opening an installation groove 100 on the valve base plate 1 at the corresponding position of the side wall 5 of the water tank, and placing a pre-embedded foundation plate 42 at the bottom of the installation groove 100. The pre-embedded foundation plate 42 is then fixed to the pre-embedded anchor screws 43 by screws. The product boasts high precision, a fast construction cycle, strong load-bearing capacity, and anti-buoyancy and anti-vibration properties. Furthermore, the water tank's panels 11 form a double-sealed structure, providing excellent leak-proof performance. In particular, even if leakage occurs in the fire pump station water tank constructed using the method provided by the present invention under special circumstances, it is only necessary to identify the leakage point, loosen the fastening screws 28 and 26, open the inner sealing pressure plate 25, and replace the inner sealing gasket 24. This not only ensures the sealing effect and extends the service life but also facilitates easy replacement, installation, and maintenance.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
