Description

Technical Field

[0001] The present invention relates to the technical field of the design and construction of prefabricated buildings, and particularly relates to a prefabricated wall component, a prefabricated water tank and an assembly method of the 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. At present, 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 of the construction market.

[0003] At present, 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 prefabrication technology for reinforced concrete water tanks generally has a long construction period and poor construction feasibility. According to the overall stress of the water tank for working condition analysis, the pool wall is split into solid precast components according to the conventional prefabricated building idea, and the joints of the components are connected by wet connection to achieve the design concept equivalent to cast-in-place.

[0004] However, the existing technology does not fully consider the stress principle of the water tank structure, and splits the components according to different parts, and there are many types of components. Even if the component sizes are deliberately merged, the stress and reinforcement are different at different positions and parts of the water tank, which does not conform to the design concepts of prefabrication standardization and modularization. In addition, the component sizes are not optimized according to the stress mode, and the water tank components themselves are large in volume, which limits 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 order to ensure the integrity of the water tank in the existing technology, the joints of the components are connected by wet connection. 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. The components need to have multi-sided steel bars, the production is more troublesome, and the steel bar connection construction is inconvenient. There are many types of components. If the joint structure is unreasonable, this position is likely to become a weak area for stress and waterproofing, and it is not easy to realize the transformation of the pool body and the replacement of components.

Detailed description of the specific implementation

[0047] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Embodiment

[0048] This embodiment provides an assembled wall component, which is applicable to building retaining walls, pool walls, etc. The assembled wall component includes several main wall precast components 1 and connecting parts, etc.

[0049] As Figure 1 and Figure 2 shown, the main wall precast component 1 includes a main wall body 11 that constitutes the main part of the wall. Vertical buttress rib plates 3 are provided on the left and right ends of the main wall body 11.

[0050] The connecting parts play a connecting role and mainly include bolt parts 4 and hinge parts 5, etc.

[0051] The assembled wall is formed by successively assembling several main wall precast components 1 at the ends to form a front wall. The ends of the buttress rib plates 3 of adjacent main wall precast components 1 are correspondingly abutted to form a joint. The connecting parts connect adjacent main wall precast components 1 and their end buttress rib plates 3 to achieve dry and non-rigid connection between the main wall precast components 1.

[0052] The prefabricated wall component may further include a corner prefabricated member 2, such as Figure 3 and Figure 4 shown. The corner prefabricated member 2 includes a corner main body 21, and buttress rib plates 3 are also provided on both end sides of the corner main body 21. The planes where the buttress rib plates 3 are located on both sides of the corner prefabricated member 2 have a certain included angle. The corner prefabricated member 2 is used for the corner part of the wall, and the size of the included angle between the planes where the buttress rib plates 3 are located on both sides can be designed according to the corner angle. Usually, when a right-angle corner is required for the wall, the planes where the buttress rib plates 3 on the corner prefabricated member 2 are located form a 90° included angle. The height of the corner main body 21 is the same as that of the main wall main body 11, which is the height of the wall. The buttress rib plates 3 on the corner prefabricated member 2 are adapted to the shape and size of the buttress rib plates 3 on the main wall prefabricated member 1 and can be correspondingly butted during assembly.

[0053] In one embodiment, one side of the buttress rib plate 3 vertically extends towards one side surface of the main wall main body 11, and the other side of the buttress rib plate 3 is flush with the other side surface of the main wall main body 11, that is, in the same plane. The end cross-section of the buttress rib plate 3 has a shape that is wider at the lower part and narrower at the upper part, and the thickness of the part extending from one side of the main wall main body 11 is the same up and down.

[0054] Correspondingly, the buttress rib plates 3 on the corner prefabricated member 2 also extend from one side of the corner main body 21, the other side of the buttress rib plates 3 is flush with the inner side of the corner main body 21, and the thickness of the extended part of the buttress rib plates 3 is the same up and down.

[0055] Such as Figure 5 shown. During the assembly of the wall, the main wall prefabricated members 1 are sequentially butted at the ends, and the corner prefabricated member 2 is used to assemble with the main wall prefabricated members 1 at the corner part to realize the corner of the wall. The buttress rib plates 3 on adjacent prefabricated members are located on both sides of the joint. Bolt holes are provided on the extended parts of the buttress rib plates 3, and the bolt holes on adjacent buttress rib plates 3 correspond to each other. The bolt member 4 passes through the bolt holes for connection and fixation. The bolt member 4 includes a straight screw rod, a nut and a water-swellable rubber washer. The straight screw rod passes through the bolt holes on adjacent buttress rib plates 3, water-swellable rubber washers are sleeved at both ends, and the nut is tightened from both ends to realize fixed connection and waterproofing. The bolt holes are preferably provided at the outer 1 / 3 of the extended part of the buttress rib plate for easy installation and to ensure stability.

[0056] One side of the buttress rib plate 3 flush with the main wall body 11 / corner body 21 is connected via a hinge member 5. Specifically, the hinge member 5 includes a central rotating shaft and two wing plates rotatably connected to the central rotating shaft; hinge mounting steel plates are embedded at corresponding positions on the buttress rib plate 3 or the main wall body 11 or the corner body 21, and the concave depth at the embedded hinge steel plate is greater than or equal to 10 mm. The wing plates of the hinge member 5 are welded to the embedded hinge mounting steel plates to achieve flexible connection, which can adapt to the small deformation and displacement between adjacent components.

[0057] In another embodiment, the buttress rib plates 3 can extend vertically from both sides of the main wall body 11 (not shown in the figure). When adjacent main wall precast components 1 are assembled, the adjacent buttress rib plates 3 are connected and fixed by bolt members 4 at the extending parts on both sides. Correspondingly, the buttress rib plates 3 on the corner precast components 2 can also extend out on both sides to adapt to the buttress rib plates 3 on the main wall precast components 1.

[0058] As Figure 2 and Figure 4 shown, a force - transmitting gasket 31 is pasted on the butt - joint surface of the buttress rib plate 3. The force - transmitting gasket 31 is a flexible gasket, which can be made of nitrile rubber cork and is bonded to the contact surface of the buttress rib plate 3 using a one - component chloroprene - phenolic adhesive; the thickness of the force - transmitting gasket 31 is controlled at about 3 mm. When the precast components are assembled, the force - transmitting gasket 31 is located in the joint between adjacent buttress rib plates 3, which plays a role in weakening the concentrated stress and can compensate for the flatness of the contact surface of the components.

[0059] A bottom plate overhang 12 is provided at the lower part of the main wall precast component 1 and the corner precast component 2. The bottom plate overhang 12 is preferably an overhanging part extending outward in full size, and the extension length should not be less than the width of the lower end of the buttress rib plate 3. Setting the bottom plate overhang 12 enlarges the bottom end face area of the precast component, and at the same time serves as a base to increase the strength of the bottom, making the precast component easier to install, with better installation stability and stronger force - bearing structure.

[0060] The prefabricated wall component of this embodiment can be assembled and constructed into retaining walls, pool walls, etc. It has few component types, a simple structure, no reinforcement protruding from the side of the components, and is connected by dry methods using connecting pieces, reducing the time for steel bar binding and in - situ concrete pouring and curing. The installation construction is convenient and fast, and the construction period is short. Embodiment

[0061] This embodiment provides a prefabricated pool, which is assembled by using the wall component described in Embodiment 1.

[0062] Specifically, according to the design of the pool size and shape, select the corresponding number of main wall precast components 1 and the corresponding number of corner precast components 2 and assemble them in a certain order in sequence to form a circular closed pool wall; and connect and fix the joints between adjacent main wall precast components 1 and / or corner precast components 2 via connecting pieces.

[0063] As Figure 6 shown, the buttress rib plate 3 extends towards the outside of the pool on both the main wall body 11 and the corner body 21, that is, the buttress rib plate 3 extends towards the outside of the pool. When the connecting piece makes a dry connection to the joint, the bolt piece 4 connects the adjacent buttress rib plates 3 on the outside of the pool, and the hinge piece 5 connects the adjacent precast components on the inner side wall of the pool, which is the case of the assembled pool using the internal water condition.

[0064] As Figure 1 , Figure 3 and Figure 6 shown, the outer sides of the lower parts of the main wall precast component 1 and the corner precast component 2 are both provided with a bottom plate overhang 12. The bottom plate overhang 12 is an overhang part extending outwards in full size, and the extension length is not less than the width of the lower end of the buttress rib plate 3. Preferably, the extension length of the bottom plate overhang 12 is adapted to the width of the lower end of the buttress rib plate 3. The setting of the bottom plate overhang 12, in cooperation with the buttress rib plate 3, enhances the overall stress structure of the precast component, is more adaptable to the stress mode of the pool, and while meeting the stress requirements, can save the materials used for the precast component, and the solid volume of the precast component becomes smaller and the weight is lighter.

[0065] As Figure 2 and Figure 8 shown, the inner side of the lower part of the main wall precast component 1 is also provided with a bottom plate inlay 13. The bottom plate inlay 13 extends inwards in a partial size, and reinforcing bars 6 are arranged on the side surface of the bottom plate inlay 13 and a water stop steel plate 7 is embedded. The reinforcing bars 6 on the side surface of the bottom plate inlay 13 are double-layer and double-way stress-bearing steel bars arranged parallel up and down; the water stop steel plate 7 is embedded on the inner-facing side of the bottom plate inlay 13 and is horizontally centered between the double-layer reinforcing bars 6.

[0066] As Figure 4 shown, the inner side of the lower part of the corner precast component 2 is provided with reinforcing bars 6 extending inwards. The reinforcing bars 6 are also double-layer and double-way stress-bearing steel bars arranged parallel up and down.

[0067] In one implementation, the pool further includes a plurality of precast bottom plates (not shown in the figure). The peripheral side surfaces of the precast bottom plates are provided with reinforcing bars 6 and water stop steel plates 7. The reinforcing bars 6 and water stop steel plates 7 on the side surfaces of the precast bottom plates are correspondingly adapted to the reinforcing bars 6 and water stop steel plates 7 on the bottom plate inlay 13. After the assembly connection of the pool wall is completed, the precast bottom plates are assembled and cast for curing to complete the construction of the pool bottom. The pool bottom is cast and wet-connected using precast bottom plates, which can effectively reduce wet operations, increase the precast rate, and at the same time ensure the reliability of the joint connection of the pool bottom.

[0068] Another implementation method is that no precast bottom slab is set, and the entire bottom slab of the pool is constructed by in-situ casting. The bottom slab steel bars are tied and connected to the steel bars protruding from the inner side of the 13-sided inner projection of the bottom slab and the lower inner side of the corner precast member 2, and then concrete pouring and curing are carried out. Constructing the bottom of the pool with an in-situ cast bottom slab can effectively ensure the flatness of the bottom of the pool and the overall performance of the pool body.

[0069] The 13-sided inner projection of the bottom slab is set to be spliced with the precast bottom slab or the in-situ cast bottom slab, so that the horizontal joint is located in the bottom area of the pool, and there is only a vertical joint in the vertical pool wall, ensuring the integrity of the pool wall and the bottom slab in the adjacent area. The construction of the pool wall is more convenient, and the accuracy is easier to control. Moreover, the joint position is reasonable. This shape takes into account the practical operation of various links such as design, production, and transportation, and has strong feasibility.

[0070] As Figure 2 and Figure 4 shown, a force transfer gasket 31 is provided on the splicing end face (i.e., the joint docking face) of the buttress rib plate 3, which is used to compensate for the flatness of the splicing end face of the component and play a role in weakening the concentrated stress, making it easy to control the installation accuracy of the pool and easier to meet the construction requirements. The force transfer gasket 31 can be continuously arranged or intermittently arranged by several pieces.

[0071] This prefabricated pool takes both waterproofing and anti-corrosion into consideration. The precast components are based on self-waterproofing, with joint waterproofing as the key point, supplemented by waterproof treatment of special parts, forming a complete waterproof system. Specifically, the surfaces of the main wall precast member 1 and the corner precast member 2 are coated with waterproof paint or waterproof coiled material during factory production, that is, the surfaces of the main wall precast member 1 and the corner precast member 2 are covered with a complete waterproof layer. This can reduce the on-site operation time and improve the waterproofing and anti-corrosion quality.

[0072] Joint waterproofing is the key point. As Figure 2 、 Figure 4 and Figure 7 shown, vertical through-sealed grooves 32 are provided on the splicing end face of the buttress rib plate 3. The number of the sealed grooves 32 is not less than two, and a continuous water-swelling rubber strip is provided in the sealed grooves 32. The sealed grooves 32 on adjacent buttress rib plates 3 correspond to each other. During assembly, the sealed grooves 32 correspond to each other, and the water-swelling rubber strips therein abut against each other to achieve multi-channel waterproof sealing of the joint. The bolt holes are opened between the two side sealed grooves 32, and the bolts 4 installed on the bolt holes are provided with water-swelling rubber washers, which play the role of multi-channel waterproof lines and various forms of waterproofing. The force transfer gasket 31 is also located between the two side sealed grooves 32, avoiding the corrosion of the force transfer gasket 31 and at the same time avoiding the influence of the setting of the force transfer gasket 31 on the continuity of the joint seal.

[0073] After the full water test, according to the waterproof test situation, waterproof coiled material can also be attached to the surface of the joint to further ensure the waterproof performance of the joint.

[0074] For the prefabricated pool of this embodiment, its pool wall is assembled by a number of main wall precast members 1 and a number of corner precast members 2. The buttress rib plates 3 provided at both ends of the main wall precast members 1 and the corner precast members 2 are in corresponding contact to form a joint. The adjacent buttress rib plates 3 are tightly connected through connectors, realizing the dry connection between the precast members. The structure of this prefabricated pool is decomposed into modular precast components, with few types of precast components and a simple structure, which is convenient for standardized design, manufacturing and assembly construction; the buttress rib plates 3 are designed on both sides of the joint part, optimizing the stress condition of the pool precast components. The joint adopts a dry connection method with the cooperation of connectors and the buttress rib plates 3, eliminating the in-situ casting and curing links of the joint, improving the construction efficiency, and providing the possibility for the replacement and maintenance of the pool components in the later stage; and reducing the multi-sided reinforcement of the precast components. The main wall precast members 1 and the corner precast members 2 are only provided with reinforcement bars 6 on the inner side of the lower part, which is convenient for manufacturing and transportation. The surface of the precast components is covered with a complete waterproof layer, and the joint adopts multiple waterproof lines for waterproofing, and the anti-corrosion and waterproof performance of the pool is good. Embodiment

[0075] This embodiment provides an assembly method for a prefabricated pool, which is applicable to the assembly construction of the prefabricated pool described in Embodiment 2.

[0076] The assembly method of this prefabricated pool includes the following steps:

[0077] Step S100: Lay a concrete cushion as the base for the pool assembly.

[0078] According to the design requirements such as the size and shape of the pool, lay a concrete cushion, and use it as the base for the pool assembly after curing to meet the requirements.

[0079] Step S200: According to the design size and shape requirements of the pool, prepare the corresponding number of main wall precast members 1 and corner precast members 2 to adapt to the length of the pool wall and the number of corners; mark the assembly positions of the main wall precast members 1 and the corner precast members 2 on the base, and hoist the corresponding precast members to the marked positioning positions; adjust the positions of the precast members so that the contact surfaces of the buttress rib plates 3 of the adjacent precast members are in corresponding abutment, and the bolt holes, sealing grooves 32 and water-swelling rubber strips on them are in corresponding abutment, providing conditions for subsequent tight connection and waterproof sealing.

[0080] There are at least two positioning holes on the buttress rib plate 3. When adjusting the position of the precast member, a straight screw rod can be inserted into the positioning hole for auxiliary positioning correspondence.

[0081] Step S300: For the precast components with adjusted positions, on the extended parts outside the adjacent retaining wall rib plates 3, bolt components 4 are used for connection. The straight screw rods of the bolt components 4 pass through the bolt holes, and both ends are tightened with nuts to realize the tight connection of the two-side precast components by pulling them together; the joints are connected by hinge components 5 on the inner side of the pool wall. The wing plates on both sides of the hinge components 5 are welded to the movable hinge installation steel plates embedded in the precast components to realize the flexible connection on the inner side. After all the main wall precast components 1 and corner precast components 2 are connected in sequence, a circular and closed pool wall is formed.

[0082] Step S400: When the pool bottom slab is composed of multiple precast bottom slabs, mark the positioning positions of the precast bottom slabs on the base layer, hoist the precast bottom slabs to the positioning positions. After all the precast bottom slabs are hoisted to the positioning positions, check the splicing situation, and then perform full-weld connection on the water-stop steel plates 7 between the precast bottom slabs and between the precast bottom slabs and the inner projection 13 of the bottom slab, tie the out-of-bar 6, and perform cast-in-place concrete curing on the joints. The integrity of the pool is good, the curing time is short, and the construction period is saved.

[0083] When the precast bottom slab is not provided for the pool bottom slab, bind the steel bars at the inner bottom of the pool, and bind and connect them with the inner projection 13 of the bottom slab and the out-of-bar 6 at the lower inner side of the corner precast component 2. After the binding is completed, perform overall cast-in-place concrete curing to obtain a pool bottom slab with good flatness and integrity.

[0084] The assembly method of this embodiment is based on the structure of the prefabricated pool for assembly construction. The construction operation steps are few, the precast components are positioned and installed, and the construction accuracy is easy to control. The pool wall is constructed by dry connection, with a short construction period and convenient and fast operation; first, the pool wall is assembled, and then the precast bottom slab is assembled or the cast-in-place bottom slab is poured. The construction operation is convenient, and it is easy to control the installation accuracy, waterproof performance and flatness of the bottom slab of the pool wall. The integrity of the bottom structure of the pool body is good.

[0085] Although the embodiments of the present invention have been shown and described above, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
