Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to a removable composite plate. In addition, the present application also relates to a water treatment device comprising the removable composite plate. Background Art

[0002] The water tanks of traditional water treatment devices are usually built with concrete structures. During the construction of concrete structures, the on-site workload of reinforced concrete structures is large, the civil construction period is long, and a large amount of dust, noise, sewage, construction waste and other environmental pollution are generated during the construction process. In addition, high requirements are placed on professional and technical workers such as reinforcement workers and carpenters. At the same time, construction waste pollution will be brought about during the transformation and removal of concrete structures.

[0003] For example, Chinese patent application number 201911122954.9 discloses a removable trapezoidal corrugated tank body, which is formed by combining multiple trapezoidal corrugated plates to form a removable wall panel. Curved structural designs like those in the aforementioned patent are not conducive to structural reinforcement and equipment fixation within the tank body, as well as fixed connection to its base plate. Therefore, removable wall panels with similar structural designs have certain drawbacks. For example, when only trapezoidal corrugated plates are used as the wall plates of the pool body, due to the wall plate structure formed by grooves and protrusions, the inner wall of the pool body cannot achieve the smooth wall surface required by our common normal pool body, which is not conducive to strengthening the internal structure and fixing the equipment. In addition, the connection strength and sealing performance between multiple trapezoidal corrugated plates, especially when using bolt-clamped skid-mounted installation, the connection parts of adjacent trapezoidal corrugated plates are in a disconnected state, which will cause the force strength here to be weakened. Even with rubber plates or other sealing measures, it is difficult to avoid deformation due to insufficient strength and single sealing measures, which will lead to water leakage at the connection or bolt hole, and the lower port is curved, which is particularly not conducive to achieving bolt-skid-mounted sealing connection with its bottom plate.

[0004] Therefore, in response to the above technical problems, how to provide a removable composite panel with higher connection strength, better sealing performance and smooth wall surface is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this application is to provide a removable composite panel, which is composed of multiple removable prefabricated panels. By using the bonding method of the bent edges, multiple seals are achieved between two adjacent prefabricated panels under the joint action of the special sealing connector of the present invention, so that its sealing performance is higher. At the same time, by connecting this backboard with the corrugated board, while reducing the overall thickness and weight of the board, the strength of the composite panel can be increased to a certain extent, preventing the composite panels from deforming due to force when disconnected, thereby causing water leakage. It can also simultaneously achieve a smooth wall surface for the inner wall of the pool body, which is beneficial to the structural reinforcement and equipment fixation inside the pool body, as well as to achieve a removable bolt-pry sealed connection with its bottom plate.

[0006] To achieve the above-mentioned object, the present application provides a removable composite panel, comprising a plurality of groups of fixedly connected prefabricated panels, wherein any group of the prefabricated panels comprises:

[0007] corrugated sheet with raised features on both sides;

[0008] A back panel is fitted with the raised feature on one side of the corrugated board, and the four sides of the back panel are bent 90 degrees away from the corrugated board to form bent edges, wherein the orthographic projection of the bent back panel in the direction of the corrugated board is a rectangle, and the rectangle can at least cover the corrugated board;

[0009] Among them, the two bent edges of the two adjacent prefabricated panels are fitted together and fixed by a first bolt passing through the two bent edges, and a connecting piece for connecting the two adjacent prefabricated panels is provided at the fitting position, and the connecting piece is fixedly connected to the corrugated board and the backboard.

[0010] Preferably, the corrugated board and the back plate are welded to form an integral piece, or the corrugated board is pressed onto the back plate via the connecting piece.

[0011] Preferably, the connector is a T-shaped connector, and the T-shaped connector includes:

[0012] A connecting plate is used to connect two adjacent prefabricated plates, wherein the back plate, the corrugated plate and the connecting plate have an overlapping portion, and a second bolt is passed through the overlapping portion to press the corrugated plate onto the back plate;

[0013] The vertical plate is arranged perpendicular to the connecting plate and extends in a direction away from the back plate.

[0014] Preferably, the extended vertical plate is fixed on a vertical column, or the extended vertical plate is fixed to the foundation.

[0015] Preferably, the end of the extending end of the vertical plate is flush with the plane where the outer edge of the raised feature is located, so that the raised feature abuts against the column, or the raised feature abuts against the foundation.

[0016] Preferably, the back plate is arranged facing the interior of the pool body.

[0017] Preferably, evenly distributed protrusions are provided on the back plate in areas not in contact with the protruding features.

[0018] Preferably, the corrugated board has a horizontal extension direction of the corrugations.

[0019] Preferably, a rubber gasket or sealant is provided at the joint and / or overlapping portion of the two bent edges.

[0020] A water treatment device comprises any of the above-mentioned removable composite panels used as wall panels and / or bottom panels.

[0021] Compared to the aforementioned background technology, the removable composite panel of the present application comprises multiple groups of interconnected prefabricated panels. Adjacent prefabricated panels are removably connected, with a high degree of sealing at the joints, thereby ensuring a tight seal between the prefabricated panels. Furthermore, the connection between the back panel and the corrugated board not only enhances the connection strength of the corrugated board, but also reduces the thickness of the back panel while ensuring the designed strength of the back panel, thanks to the support of the corrugated board, thereby reducing waste of consumables.

[0022] Specifically, each set of precast panels consists of a corrugated sheet and a backing sheet. The corrugated sheet has raised features, and the backing sheet aligns with the raised features on one side of the corrugated sheet, providing support. The backing sheet has a flat surface on the other side. Therefore, when used as a tank wall or floor, it facilitates internal structural reinforcement, equipment fixation, and bolted, skid-type sealing connections between the wall and floor, resulting in excellent performance.

[0023] The four edges of the back panel are bent 90° away from the corrugated board to form a bent edge. When two adjacent prefabricated panels are assembled, the two adjacent bent edges fit together and are clamped together by a first bolt, forming a first seal. The provision of the bent edge enhances the stress strength around the back panel and improves the overall connection strength of adjacent back panels. At the same time, the bent edge has a certain length. When water seepage occurs, the degree of water seepage will gradually decrease as the length of the bent edge increases, thereby strengthening the seal. In addition, a connector for connecting the two prefabricated panels is provided at the point where the bent edges fit together. While ensuring the strength of the disconnection point between the two prefabricated panels, the connector's design, which overlaps with the four surfaces of the prefabricated panels, further enhances the structural strength of the prefabricated panels at their edges during assembly. This ensures that even if water seeps out of the gap between the bent edges, it will be suppressed again by the connector, forming a second seal to prevent further leakage. Compared with the design without a backboard, this provides an additional sealing measure and further enhances the structural strength of the edges of the prefabricated panels during assembly, preventing water seepage caused by deformation during skid-mounted connections.

[0024] Furthermore, when used as a tank wall or floor, the composite panels are connected by combining multiple prefabricated panels and sealed with connectors. This reduces investment costs while meeting strength requirements, replacing concrete tank or steel structure wall and floor panels, and enabling factory prefabrication. The design approach of this application solves the problem of factory prefabrication of water treatment reactors, reducing transportation costs and shortening the construction period, as well as reducing the reliance on specialized technicians on the construction site.

[0032] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] It should be noted that in this embodiment, the directions or positional relationships indicated by "upper," "lower," "front," and "back" are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this application and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction. Therefore, they should not be construed as limitations on this application. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0035] like Figure 1 As shown, in this embodiment, a removable composite panel is provided, which is composed of a plurality of fixedly connected prefabricated panels. Of course, the fixed connection here is a removable connection. Through this design method, the prefabricated panels can be prefabricated in advance, reducing transportation costs and shortening the construction period, as well as reducing the construction site's dependence on professional technicians.

[0036] Specifically, the prefabricated board includes a corrugated board 1 and a backboard 2. Figure 2 The prefabricated panels have raised features on both sides, forming a corrugated flute structure. The back panel 2 aligns with the raised features on one side of the corrugated panel 1 and is securely connected, resulting in a prefabricated panel structure with high strength. Furthermore, the clamping of the corrugated panel 1 minimizes the thickness of the back panel 2 while maintaining high strength, thus reducing waste of consumables.

[0037] It should be noted that one side of the back panel 2 aligns with the raised features of the corrugated board 1, while the other side has a flat surface, which is generally oriented toward the interior of the tank. Whether the prefabricated panel is used as a wall panel or floor panel, it can maintain the flatness of the tank's inner wall. Therefore, when used as a tank wall panel or floor panel, it can achieve all the technical advantages of a smooth inner wall. Compared with existing technologies, it can further enhance structural strength and sealing performance, achieving better application results.

[0038] In addition, the four sides of the back plate 2 have bent edges 22 that are bent 90 degrees away from the corrugated board 1. Figure 4 , and the orthographic projection of the bent backsheet 2 in the direction of the corrugated board 1 is a rectangle that covers the corrugated board 1. Generally speaking, in a prefabricated board structure, all raised features on the same side can mate with the backsheet 2, and a portion of the raised features at the edge can mate with the backsheet 2. That is, there is a certain overlap between the raised features and the backsheet 2. This overlap can then be used to achieve a fixed connection between the backsheet 2 and the corrugated board 1. Specifically, the fixed connection can be achieved by welding or bolt clamping, which will not be detailed here.

[0039] When two adjacent prefabricated panels are removably connected, the two adjacent bent edges 22 of the two prefabricated panels fit together, and the two bent edges 22 are fixed by a bolt-clamping prying method formed by a first bolt 23 running through them. Furthermore, a connector 3 is added at the fitting point of the two bent edges 22. The connector 3 can further connect the two prefabricated panels by bolt-clamping prying and cover the gap at the fitting point. Since the connector 3 has a certain overlap with both prefabricated panels, the thickness of the prefabricated panels is further increased, thereby further enhancing the structural strength of the outer edges of the two prefabricated panels. It should be noted that the connector 3 is located at the overlapping portion of the aforementioned raised features and the back panel 2, and the back panel 2, corrugated panel 1, and connector 3 are arranged in sequence, so that the back panel 2, corrugated panel 1, and connector 3 are fixedly connected.

[0040] It should be pointed out that, since the joints of the two prefabricated panels are subjected to the greatest stress when connected, a connector design structure with a higher stress-bearing strength is required. In the present application, the stress on all sides of the back panel 2 is strengthened by the bent edge 22 structure of the back panel 2, and at the same time, connectors 3 are added. Connectors 3 have a certain plate thickness and strength, thereby ensuring the structural strength of the joints of the prefabricated panels. Therefore, compared to other parts, since connectors 3 have the strongest plate thickness and strength, the strength of the joints between the two prefabricated panels can be guaranteed. At the same time, since connectors 3 overlap with the edges of each prefabricated panel by a certain width, when the prefabricated panels are assembled, it is equivalent to thickening the outer edges of the prefabricated panels again, thereby further enhancing the strength of the outer edges of the prefabricated panels, thereby achieving the multiple reinforcement of the structural strength of the weak parts required by the present invention.

[0041] Furthermore, since the bent edge 22 has a certain length, when water seepage occurs, the degree of water seepage gradually decreases as the length of the bent edge 22 increases, thereby serving as the first sealing function when connecting the prefabricated panels of the pool body of the present invention. Since a connector 3 for connecting the two prefabricated panels is also provided at the joint of the bent edge 22, even if water seeps out from the gap formed by the bent edge 22, it will be suppressed by the connector 3. This is equivalent to an additional anti-water seepage sealing measure compared to a design without a back panel 2, thereby achieving the multi-reinforced and multi-anti-water seepage sealing effect required by the present invention.

[0042] Compared to the configuration without a backboard 2, the present invention has four bent edges 22 on all four sides, making it very easy to achieve bolt-on clamping and skidding of the bent edges 22 while maintaining the sealing effect and structural strength of the clamping. If only corrugated board 1 or corrugated board is used, the two sides parallel to the corrugated channel can achieve bolt-on clamping and skidding, but the upper and lower ends of the channel are curved, making it difficult to achieve a similar bolt-on clamping and skidding installation as described above, and the sealing connection effect after bolt-on skidding cannot be guaranteed.

[0043] It should be noted that the above points out that the corrugated board 1 can be connected to the backboard 2 by welding, or by bolt clamping and prying; after the backboard 2 and the corrugated board 1 are welded, the two form a whole. If two prefabricated boards are connected, they still need to be connected through the connecting piece 3, and the connecting piece 3 connects the two prefabricated boards by bolt clamping and prying.

[0044] If the back panel 2 and the corrugated board 1 are assembled by bolt clamping, the clamping and assembly of the back panel 2 and the corrugated board 1 can be completed simultaneously through the connecting piece 3; that is, the bolts can penetrate the back panel 2, the corrugated board 1 and the connecting piece 3 at the same time, and the back panel 2 and the corrugated board 1 on the two prefabricated boards are fixed and clamped on the connecting piece 3, thereby completing the clamping and assembly.

[0045] In other words, the present application has at least two bolt-clamped skid-mounted parts, one is the bolt-clamped skid-mounted parts of the bent edge 22, and the other is the bolt-clamped skid-mounted parts of the connector 3, the back panel 2, and the corrugated board 1. Among them, in the bolt-clamped skid-mounted parts of the connector 3, the back panel 2, and the corrugated board 1, there are two ways. One is that the back panel 2 is welded to the corrugated board 1 and then clamped and skid-mounted with the connecting plate 31, so that the two prefabricated boards are fixedly connected together, and the back panel 2, the corrugated board 1, and the connector 3 are kept fixedly connected; the other is that the back panel 2, the corrugated board 1, and the connecting plate 31 are connected together by bolt-clamped skid-mounted parts, and the back panel 2, the corrugated board 1, and the connector 3 are also fixedly connected under the premise that the two prefabricated boards are fixedly connected. It should be noted that the structural form of the connector 3 here can be of various types, as long as it can realize the bolt-clamped skid-mounted parts and the fixed connection of the two prefabricated boards, which will not be described in detail here.

[0046] Based on the above embodiment, the connector 3 of the present application is preferably a T-shaped connector, which includes a connecting plate 31 and a vertical plate 32. The connecting plate 31 is used to connect two adjacent prefabricated panels. Specifically, the back panel 2, the corrugated board 1, and the connecting plate 31 have overlapping portions. After the second bolt 24 penetrates the overlapping portion, the corrugated board 1 is pressed against the back panel 2, thereby forming a bolt-clamping skid assembly. Of course, if the back panel 2 and the corrugated board 1 are connected by welding, the connecting plate 31 only needs to be skid-assembled with the integral bolt-clamping skid assembly formed by the back panel 2 and the corrugated board 1.

[0047] The vertical panels 32 are arranged perpendicular to the connecting panels 31 and extend away from the back panel 2. There are two situations: when the precast panel is used as a wall panel or a bottom panel. When the precast panel is used as a wall panel, the extended vertical panels 32 are fixed to the vertical columns 4, which are fixed to the concrete foundation, thereby forming a stable support. When the precast panel is used as a bottom panel, the vertical panels 32 can be fixed to the foundation, thereby ensuring a fixed bottom panel.

[0048] On this basis, the end of the extended end of the vertical plate 32 is flush with the plane where the outer edge of the raised feature is located, so that the raised feature is abutted against the column 4 and fixed to the column 4 by welding, or the raised feature is abutted against the foundation and fixed to the foundation by embedded parts, etc., which will not be described in detail here.

[0049] It should be noted that, no matter the prefabricated panels are used as wall panels or bottom panels, their back panels 2 are arranged facing the interior of the pool body.

[0050] In addition, please refer to Figure 2 and Figure 5Evenly distributed protrusions 21 are provided on the back sheet 2 in areas not aligned with the raised features. These protrusions 21 enhance the strength of the back sheet 2 while also reducing its thickness. This reduces the thickness of the back sheet 2 while maintaining its strength, saving on consumables. Similarly, the configuration of the corrugated board 1 achieves the same effect, reducing the thickness of the back sheet 2 while maintaining its strength.

[0051] To further enhance the support provided by the corrugated board 1, the present application arranges the corrugations of the corrugated board 1 to extend horizontally, thereby ensuring that the raised features can mate with the uprights 4 and provide a certain degree of support. Of course, the corrugations can also extend vertically, but this approach offers a certain degree of strength disadvantage compared to a horizontal approach. This will not be discussed in detail here, as all such approaches fall within the scope of protection provided by the present application.

[0052] In addition, in order to further enhance the sealing effect of the prefabricated panel joints, rubber gaskets or sealants are provided at the joints and / or overlapping portions of the two bent edges 22 to ensure that water does not seep in there.

[0053] It should be emphasized that before each independent prefabricated board of the present invention is connected to each other, the corrugated board 1 and the backboard 2 must be tightly adhered together in advance to form an organism, that is, a prefabricated board. Between each two prefabricated boards, a second bolt 24 that matches the T-shaped connector is preferably selected, and the bolts 24 are clamped and pried together using the planar openings that overlap with the T-shaped connector, and are sealed by rubber gaskets or structural adhesives.

[0054] On the outside of the prefabricated panels, vertical columns 4 and the vertical plates 32 of the T-shaped connectors are welded or bolted together to form a single unit. Thus, the wall panels or bottom panels of the water treatment device of the present invention are formed by sealingly connecting the two prefabricated panels together using the T-shaped connectors. The vertical plates 32 of the T-shaped connectors then serve as lateral reinforcements for the wall panels, while the columns 4 serve as vertical supports for the wall panels of the present invention. This interweaving of the vertical and horizontal reinforcements ensures that the composite panels of the present invention can be assembled in a removable, skid-mounted manner when clamped with bolts.

[0055] In addition, the present application also provides a water treatment device, which includes any of the above-mentioned removable composite panels used as wall panels and / or bottom panels. Therefore, the water treatment device can also meet the future requirements of factory-based prefabrication of water treatment device pools, on-site bolt clamping, and removable on-site assembly.

[0056] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0057] This document uses specific examples to illustrate the principles and implementation methods of this application. The description of the above examples is only intended to help understand the method and core ideas of this application. It should be noted that for those skilled in the art, without departing from the principles of this application, various improvements and modifications can be made to this application, and such improvements and modifications also fall within the scope of protection of the claims of this application.
