Description

Technical Field

[0001] The present invention relates to the technical field of the design and construction of prefabricated water tanks, and particularly to a prefabricated water tank. Background Art

[0002] Under the background of the transformation and upgrading of the manufacturing industry, prefabrication technology has been widely used in the construction industry due to its many advantages. Currently, prefabrication technology is most widely used in the field of building construction, and the construction technology system is becoming increasingly mature. In recent years, many explorations have been carried out on the application of reinforced concrete prefabrication technology in the municipal field, such as bridge projects, pipe gallery projects, subway underground stations, and tunnel projects. Water purification and sewage treatment plants in the municipal field are an important part of infrastructure construction and occupy a large share in the construction market.

[0003] Currently, the water tank structures in projects such as water plants are generally of reinforced concrete structure, which is a traditional on-site full-cast-in-place structure. The development process of its prefabricated construction method is in its infancy. The existing prefabricated technology for reinforced concrete water tanks generally conducts working condition analysis according to the overall force of the water tank, and splits the pool wall into solid precast components according to the conventional prefabricated building idea. The joints of the components are connected by wet methods to achieve the design concept equivalent to cast-in-place.

[0004] However, the existing technology does not fully consider the force principle of the water tank structure, and splits the components according to different parts, resulting in a large number of component types. Even if the component sizes are deliberately merged, the forces at different positions and parts of the water tank are different, and the reinforcement is also different, which does not conform to the design concepts of prefabricated standardization and modularization. In addition, the component sizes are not optimized according to the force mode. The water tank components themselves are large in size, and the rectangular cross-section components waste materials and are restricted in construction. To ensure the assembly effect, conventional prefabrication has high precision requirements for the finished components, especially the joints, and the production and manufacturing are difficult.

[0005] In addition, in the existing technology, to ensure the integrity of the water tank, the joints of the components are connected by wet methods. The wet connection is similar to cast-in-place, which requires grouting and curing processes, prolonging the construction period and failing to reflect the advantages of prefabrication in terms of construction period; it requires multi-sided reinforcement, the component production is more troublesome, and the steel bar connection construction is inconvenient; there are many forms, and if the node structure is unreasonable, this position is likely to become a weak area for force and waterproofing; it is not easy to realize the transformation of the pool body and the replacement of components.

[0043] The following will describe the embodiments of the present invention in detail with reference to the drawings.

[0044] As Figure 1As shown in the figure, this embodiment provides a prefabricated pool, which includes a number of standard precast components 1, a number of corner precast components 2 and connection components. The pool wall of the pool is assembled by a number of standard precast components 1 and a number of corner precast components 2, and is connected by the connection components.

[0045] Specifically, the standard precast component 1 includes a pool wall main body 11 and buttress rib plates 3 arranged at the left and right ends of the pool wall main body 11. The buttress rib plates 3 are arranged towards the outside of the pool.

[0046] The corner precast component 2 includes a corner main body 21 and buttress rib plates 3 arranged at the left and right ends of the corner main body 21. The planes where the two buttress rib plates 3 of the corner precast component 2 are located have a certain included angle to adapt to the corner angle of the pool wall. When the pool has a right-angle corner, the planes where the two buttress rib plates 3 of the corner precast component 2 are located are perpendicular planes.

[0047] The connection component plays a role in connecting and fastening.

[0048] Among them, a number of standard precast components 1 and a number of corner precast components 2 are combined and assembled according to the design requirements of the pool to form the pool wall. Between adjacent standard precast components 1, between adjacent standard precast components 1 and corner precast components 2, and between adjacent corner precast components 2, they are butted through the buttress rib plates 3. A joint is formed between adjacent buttress rib plates 3 (i.e., the butted buttress rib plates 3), and is connected and fixed by the connection components.

[0049] One implementation is, as Figures 1 to 5 shown, the contact between adjacent buttress rib plates 3 is a vertical single-plane contact, that is, the contact surface (end face) of the buttress rib plate 3 is a flat plane, and the formed joint is a single-plane joint.

[0050] Another implementation is that the contact between adjacent said buttress rib plates 3 can be vertical fitting contact (not shown in the figure). That is, the contact surfaces (end faces) of adjacent buttress rib plates 3 are non-single planes that cooperate with each other, and can be provided with matching vertical joints and vertical ribs, which plays a role in further extending the joint and making the assembly positioning more accurate.

[0051] As Figures 1 to 5 shown, the buttress rib plate 3 is an enlarged end at the end of the pool wall main body 11 and the corner main body 21. In one implementation, the buttress rib plate 3 is arranged towards the outside of the pool to adapt to the internal water condition. The buttress rib plate 3 is designed on the outside of the pool, which is convenient for connection construction from the outside after assembly. The cross-section of the buttress rib plate 3 at the end is wider at the bottom and narrower at the top, that is, the rib top is small and the rib bottom is large, and the upper and lower thicknesses of the buttress rib plate 3 are the same. Obviously, to adapt to the external soil condition (retaining wall), the position of the buttress rib plate 3 can be adjusted to the inside of the pool wall; or in the case of internal water and external soil conditions, the buttress rib plate 3 can be arranged on both sides and can extend towards the inside and the outside at the same time.

[0052] In one embodiment, the main body 11 of the pool wall and the main body 21 of the corner are pool walls with an inner inclined and / or outer inclined variable cross-section, and the wall thickness is a structure that is thicker at the bottom and thinner at the top. The top thickness of the main body 11 of the pool wall and the main body 21 of the corner is not less than 300 mm. Alternatively, the wall thickness of the pool wall is 1 / 20 to 1 / 10 of the height of the pool wall.

[0053] In another embodiment, the cross-sectional thickness dimensions of the main body 11 of the pool wall and the main body 21 of the corner are the same up and down, but the internal steel reinforcement is adjusted, and the reinforcement ratio at the lower part is higher than that at the upper part. And the wall thickness of the pool wall is within the range of 1 / 20 to 1 / 10 of the height of the pool wall to adapt to the stress model of the water pool.

[0054] The connecting assembly includes a bolt member 4 and / or a hinge member 5, etc. The bolt member 4 is preferably a straight bolt member, including a screw rod and a nut, etc. The hinge member 5 includes two side wing plates and a middle rotating shaft.

[0055] As Figure 1 shown, the buttress rib plate 3 in this embodiment extends to the outside of the water pool. The buttress rib plate 3 is provided with bolt holes at the outside part of the water pool. The screw rod passes through the bolt holes and is fixedly connected at both ends through nuts. The bolt holes are arranged at 1 / 3 of the outstretched length of the buttress rib plate 3 (near the outside), and a plurality of them are arranged at intervals up and down. A water-swelling rubber gasket is also provided. The water-swelling rubber gasket is arranged at both ends of the screw rod and is adapted to the screw rod, the bolt hole and the nut to achieve the purpose of waterproofing the bolt hole.

[0056] The buttress rib plate 3 is flush with the pool wall on the inner side of the water pool. Adjacent buttress rib plates 3 are connected through a hinge member 5 on the inner side of the water pool. Specifically, steel bars or steel plates are embedded on the inner side of the buttress rib plate 3. The wing plates of the hinge member 5 are welded and fixed to the embedded steel bars or steel plates. The two side wing plates are rotatably connected around the middle rotating shaft, and the middle rotating shaft corresponds to the joint between adjacent buttress rib plates 3. Through the connection of the hinge member 5, it can adapt to the small deformation between adjacent precast components and has a certain compensation effect. The embedded steel bars or steel plates are exposed embedded parts and should be recessed into the surface of the precast component, and the recessed depth is greater than or equal to 10 mm to ensure that the hinge member 5 is installed more stably and reliably.

[0057] As Figure 2 and Figure 4 shown, a force transmission gasket 31 is pasted on the contact surface of the buttress rib plate 3. When the precast components are assembled, the force transmission gasket 31 is located in the joint and plays a buffering role when stress is concentrated. The force transmission gasket 31 can be continuously arranged through up and down; it can also be divided into several pieces and arranged intermittently up and down. The thickness of the force transmission gasket 31 is greater than or equal to 3 mm, and it can be a nitrile rubber cork gasket, which is bonded to the concrete contact surface of the buttress rib plate 3 through a one-component chloroprene-phenolic adhesive. By setting the force transmission gasket 31, the concentrated stress can be weakened through the flexible gasket, and the flatness of the contact surface of the precast component (buttress rib plate 3) can be compensated.

[0058] As shown Figures 1 to 3 in FIG. 1, a bottom plate overhang 12 and a bottom plate inlay 13 are provided at the lower part of the standard precast member 1. The bottom plate overhang 12 is an overhang part extending outward in full size, that is, its width is the same as the width of the standard precast member 1, and it is adapted to the bottom of the buttress rib plate 3 and the main body 11 of the pool wall at the outer side of the bottom of the standard precast member 1. The setting of the bottom plate overhang 12 enhances the structural strength of the standard precast member 1, facilitates installation construction, and makes the structure more stable. The bottom plate inlay 13 is an inlay part extending inward in partial size. As shown Figure 2 in FIG. 2, the bottom plate inlay 13 extends centering towards the inner side of the pool at the bottom of the main body 11 of the pool wall, and the widths of both ends are smaller than the width of the main body 11 of the pool wall. Reinforcing bars 6 are provided on both end sides of the bottom plate inlay 13 and on the side facing the inside of the pool, and a water stop steel plate 131 is also embedded on the side of the bottom plate inlay 13 facing the inside of the pool. The length of the bottom plate inlay 13 extending towards the inside of the pool is 500 mm, which is used for splicing with the bottom plate of the pool. The setting of the bottom plate inlay 13 makes the horizontal joint of the pool located in the bottom plate area, and there is only a vertical joint for the vertical pool wall, which can effectively ensure the integrity of the pool wall and the bottom plate in the adjacent area, and is convenient for improving the overall construction quality of the pool.

[0059] As shown Figure 4 and Figure 5 in FIGS. 3 and 4, an overhang is also provided on the outer side of the lower part of the corner precast member 2, which is adapted to the bottom of the corner main body 21 and the buttress rib plate 3; there is no inlay on the inner side of the lower part of the corner precast member 2, but reinforcing bars 6 are provided. The reinforcing bars 6 on the bottom plate inlay 13 on the inner side of the lower part of the standard precast member 1 and the reinforcing bars 6 on the inner side of the lower part of the corner precast member 2 are both double-layer and bidirectional stressed steel bars. The water stop steel plate 131 is horizontally arranged on the side of the bottom plate inlay 13 facing the inside of the pool and is located between the double-layer reinforcing bars 6.

[0060] The surfaces of the standard precast member 1 and the corner precast member 2 are both coated with a waterproof coating or a waterproof coiled material. The waterproof coating and the waterproof coiled material are both processed when the precast member is produced in the factory, which can effectively reduce the on-site operation time and improve the quality of the waterproof practice.

[0061] As shown Figure 6 and Figure 7 in FIGS. 5 and 6, at least two longitudinally penetrating sealing grooves 32 are provided on the contact surface of the buttress rib plate 3, and a continuous water-swellable rubber strip 321 is provided in the sealing grooves 32. By forming multiple waterproof lines in the joints between the precast members, the effect of joint waterproofing is achieved.

[0062] The load transfer gasket 31 is arranged at the position between the two sealing grooves 32 to prevent the load transfer gasket 31 from affecting the continuity of the sealing grooves 32 and the water-swellable rubber strip 321 and ensure the waterproof effect.

[0063] It also includes a pool bottom slab (not shown in the figure), which is used to cover the inner bottom area of the pool.

[0064] In one implementation, the pool bottom slab is a cast-in-place concrete bottom slab, which is wet-connected to the inner lower parts of the standard precast member 1 and the corner precast member 2.

[0065] In another implementation, the pool bottom slab is a precast bottom slab, which is produced in the factory and dry-assembled and connected to the lower parts of the standard precast member 1 and the corner precast member 2. When the pool bottom slab is a precast bottom slab, transverse continuous sealing grooves 32, water-swelling rubber strips 321 and load-transfer pads 31 are provided on the inner side of the bottom slab overhang 13 of the standard precast member 1 and the inner lower part of the corner precast member 2, and the reinforcing bars 6 are no longer provided. Corresponding sealing grooves 32 and water-swelling rubber strips 321 are also provided on the side of the corresponding precast bottom slab to ensure good waterproof effect at the joints of the precast bottom slab. Of course, when the pool bottom slab is a precast bottom slab, the bottom slab overhang 13 extending inwards may not be provided, that is, the precast bottom slab is directly spliced with the inner bottom wall of the standard precast member 1.

[0066] Waterproof coiled materials are attached to the joint surfaces between the standard precast member 1, the corner precast member 2 and the precast bottom slab to further ensure the waterproof effect.

[0067] In one implementation, it also includes a cover plate covering the upper opening of the pool. The cover plate is a precast cover plate, and several precast cover plates are spliced to be suitable for the opening of the pool to close the opening of the pool.

[0068] In the prefabricated pool of this embodiment, the pool wall is assembled by several standard precast members 1 and several corner precast members 2, and the buttress rib plates 3 are used for corresponding contact. It creatively adopts dry flexible connection to form a new construction mode of prefabricated pool, reduces the number of reinforcing bars on the side of precast members, makes production and transportation more convenient, and has the advantages of water saving, material saving, energy saving, environmental protection and construction period saving in prefabricated projects, and is convenient for later replacement and maintenance.

[0069] The buttress rib plates 3 are spliced, and their force-bearing mode is reasonable. The force-bearing conditions of each part are similar. The precast members can realize the unification of size and reinforcement, which conforms to the characteristics of prefabricated standardization and modularization, can spread the marginal production cost, and improve the installation and construction efficiency. And the change of the pool size can be adapted by adjusting the number of precast members, which has strong practicability.

[0070] The buttress rib plates 3 are arranged with variable cross-sections and spliced at the enlarged ends, combining the force-bearing structure and the waterproof structure, expanding the contact surface area, realizing multiple and multi-channel waterproof measures, increasing the anti-seepage path, and forming an ideal waterproof joint.

[0071] Adopt dry connection and set a force transfer gasket 31 on the contact surface, which not only compensates for the precision of precast components but also improves the construction quality at the joint.

[0072] In summary, the prefabricated pool of the present invention realizes standardized and modular design, comprehensively considers all aspects of design, production, and construction, establishes a solid technical system, forms a complete set of implementation plans for prefabricated pools, and is easy to promote and apply.
