Description

Technical Field

[0001] The present invention relates to the technical field of pool wall formwork and construction technology, and particularly to a general formwork for water treatment structures. Background Art

[0002] Conventionally, cast-in-place water treatment structures usually adopt wooden formwork or combined steel formwork. Large machinery is required during the process of moving, installing, and disassembling. Not only is the installation and disassembly complex, but the target cost for customization according to the on-site size is high, and the one-time investment cost is high. Moreover, it does not have the value of being reused multiple times for other water treatment structures of the same category but different sizes. Traditional wooden formwork is often difficult to apply to small-sized circular water treatment structures. Standard wooden formwork is difficult to meet the requirements of small radius shapes at the customized thickness, and its applicability and flexibility for different sizes are relatively small. In view of this, if a set of formwork can achieve any shape and radius for water treatment structures and has high applicability, it is of great significance for improving the formwork turnover efficiency and economy of water treatment structures. Summary of the Invention

[0003] To solve the above technical problems, a general formwork for water treatment structures of the present invention only requires a set of formwork for water treatment structures with different shapes and radii, and has high turnover efficiency, good economic benefits, and application value.

[0004] To solve the above technical problems, the present invention provides a general formwork for water treatment structures, including:

[0005] Splicing formwork. Among multiple splicing formworks, adjacent two splicing formworks can be inserted into each other at their respective lateral ends to form a closed annular structure. The splicing formwork includes an inner side and an outer side arranged oppositely;

[0006] Roundness fixator. The roundness fixator includes a connecting seat connected to the inner side of the splicing formwork and two connecting arms extending along the connecting seat and arranged at an angle. Each connecting arm is provided with an adjusting socket, and the two connecting arms are symmetrically arranged along the longitudinal section of the splicing formwork;

[0007] Roundness adjusting rod. The roundness adjusting rod passes through the adjusting socket and is connected to the connecting arm. One axial end of the roundness adjusting rod is provided with a contact portion that abuts against the inner side of the plate body. By adjusting the different lengths of the contact portion extending out of the adjusting socket, the force exerted by the contact portion on the inner side of the plate body can be adjusted, thereby adapting to different bending angles of the splicing formwork;

[0008] Connecting rod. When there are multiple layers of the closed annular structure arranged longitudinally, the axial two ends of the connecting rod are used to connect the connecting seats on two adjacent splicing formworks in the longitudinal direction.

[0009] In an embodiment of the present invention, two connecting columns symmetrically arranged along the longitudinal section of the splicing template are rotatably connected to the connecting seat. The connecting columns are provided with connecting sockets radially penetrating the surface of the connecting columns and cooperatively connected to the connecting rod. The axis of the connecting column is perpendicular to the inner side surface of the splicing template.

[0010] In an embodiment of the present invention, a first adjusting thread band cooperating with the adjusting socket is axially provided on the outer surface of the roundness adjusting rod. The contact portion is a partial spherical structure. A rotating handle is provided at the other axial end of the roundness adjusting rod.

[0011] In an embodiment of the present invention, the connecting rod includes a rod body. One axial end of the rod body can be cooperatively connected to the connecting socket. A sleeve is sleeved on the other axial end of the rod body. A second adjusting thread band is axially provided on the outer surface of the rod body close to the sleeve. The second adjusting thread band is threadedly connected to an adjusting ring.

[0012] In an embodiment of the present invention, a fixed insertion block is connected to the inner side surface of the splicing template. The fixed insertion block is provided with a fixed socket penetrating along the longitudinal direction of the splicing template and a pin hole penetrating along the transverse direction of the splicing template. The connecting seat is provided with an insertion bar block cooperating with the fixed socket.

[0013] In an embodiment of the present invention, when multiple layers of the closed annular structure are longitudinally provided, two adjacent fixed insertion blocks in the longitudinal direction are spaced apart by a preset distance in the transverse direction.

[0014] In an embodiment of the present invention, first slots and first insertion blocks longitudinally distributed along the splicing template are respectively provided at the transverse two ends of the splicing template. Sealing splicing pieces respectively extend along the transverse two ends of the outer side surface of the splicing template. A sealing groove is formed between the sealing splicing piece and the outer side surface of the splicing template. The first slots and first insertion blocks between two adjacent splicing templates, and between the sealing splicing pieces and the sealing grooves can be inserted into each other.

[0015] In an embodiment of the present invention, a fixed length adjuster is further included. The fixed length adjuster includes an adjusting plate. Second slots adapted to the first insertion blocks and second insertion blocks adapted to the first slots are respectively provided at the transverse two ends of the adjusting plate.

[0016] In an embodiment of the present invention, it further includes an adjustable length adjuster. The adjustable length adjuster includes at least two adjustment units. Each adjustment unit includes a first adjustment block and a second adjustment block. A connecting spring is provided between one lateral end of the first adjustment block and one lateral end of the second adjustment block. On the other lateral end of the first adjustment block, there are third slots respectively adapted to a first insertion block and a second insertion block. On the other lateral end of the second adjustment block, there are third insertion blocks respectively adapted to a first slot and a second slot. A telescopic connector is connected between the longitudinal ends of the second adjustment blocks of the two adjustment units.

[0017] In an embodiment of the present invention, the first slot, the second slot, and the third slot are all concave circular structures, and the first insertion block, the second insertion block, and the third insertion block are convex circular structures.

[0018] The above technical solution of the present invention has the following advantages compared with the prior art:

[0019] For the general formwork of water treatment structures of the present invention, only one set of formwork is required for water treatment structures with different shapes and radii, which has a high turnover efficiency, good economic benefits and application value.

[0048] Referring to Figures 1 to 8 As shown, a general formwork for a water treatment structure of the present invention includes:

[0049] Splicing formwork 1. Among multiple splicing formworks 1, the adjacent lateral ends of two adjacent splicing formworks 1 can be inserted into each other to form a closed annular structure. The splicing formwork 1 includes an inner side and an outer side arranged oppositely;

[0050] Roundness fixer 2. The roundness fixer 2 includes a connecting seat 21 connected to the inner side of the splicing formwork 1 and two connecting arms 22 extending along the connecting seat 21 and arranged at an angle. Each connecting arm 22 is provided with an adjusting socket 23, and the two connecting arms 22 are symmetrically arranged along the longitudinal section of the splicing formwork 1;

[0051] Roundness adjustment rod 3, the roundness adjustment rod 3 passes through the adjustment socket 23 and is connected to the connecting arm 22. One axial end of the roundness adjustment rod 3 is provided with a contact portion 31 that abuts against the inner side surface of the plate body. By adjusting the different lengths of the contact portion 31 protruding from the adjustment socket 23, the force exerted by the contact portion 31 on the inner side surface of the plate body can be adjusted, thereby adapting to different bending angles of the splicing template 1;

[0052] Connecting rod 4. When there are multiple layers of the closed annular structure arranged longitudinally, both axial ends of the connecting rod 4 are used to connect the respective connecting seats 21 on two adjacent splicing templates 1 in the longitudinal direction.

[0053] Specifically, referring to Figure 3 As shown, two connecting columns 24 symmetrically arranged along the longitudinal section of the splicing template 1 are rotatably connected to the connecting seat 21. The connecting columns 24 are provided with connecting sockets 25 that radially penetrate the surface of the connecting columns 24 and are cooperatively connected with the connecting rod 4. The axis of the connecting column 24 is perpendicular to the inner side surface of the splicing template 1. Through the above setting, the angle of the connecting socket 25 can be rotated to adjust the connecting angle of the connecting rod 4.

[0054] Specifically, referring to Figure 4 As shown, a first adjustment thread band 32 that cooperates with the adjustment socket 23 is axially provided on the outer surface of the roundness adjustment rod 3. The contact portion 31 is a partial spherical structure. A rotary handle 33 is provided at the other axial end of the roundness adjustment rod 3, and the adjustment of the roundness adjustment rod 3 can be realized manually or mechanically.

[0055] Specifically, referring to Figure 5 As shown, the connecting rod 4 includes a rod body 41. One axial end of the rod body 41 can be cooperatively connected with the connecting socket 25. A sleeve 42 is sleeved on the other axial end of the rod body 41. A second adjustment thread band 43 is axially provided on the outer surface of the rod body 41 near the sleeve 42. The second adjustment thread band 43 is threadedly connected with an adjustment ring 44. In this embodiment, one axial end of the rod body 41 and the connecting socket 25 are threadedly connected. During use, the two rod bodies 41 are respectively screwed into the roundness fixators 2 with adjacent bevel angles. The sleeve 42 is sleeved on one of the rod bodies 41. After aligning the two rod bodies 41 in the same straight line, the sleeve 42 is sleeved on the other rod body 41, and then the adjustment ring 44 is rotated to abut against both ends of the sleeve 42 to realize the fixed connection of the two rod bodies 41. Through the above setting, the connection between adjacent roundness fixators 2 is enhanced, and the overall roundness can be adjusted better.

[0056] Specifically, referring to Figure 6As shown, a fixed insert block 5 is connected to the inner side surface of the splicing template 1. The fixed insert block 5 is provided with a fixed socket 51 penetrating along the longitudinal direction of the splicing template 1 and a pin hole 52 penetrating along the transverse direction of the splicing template 1. The connecting seat 21 is provided with a strip block 26 adapted to the fixed socket 51. In this embodiment, the strip block 26 is an arc-shaped block, and the fixed socket 51 is an arc-shaped opening. After the strip block 26 is inserted into the fixed socket 51, fixation is achieved by inserting a pin into the pin hole 52.

[0057] Specifically, referring to Figure 1 As shown, when there are multiple layers of the closed annular structure longitudinally, the two adjacent fixed insert blocks 5 in the longitudinal direction are spaced a preset distance in the transverse direction.

[0058] Specifically, referring to Figure 2 As shown, first slots 11 and first insert blocks 12 distributed longitudinally along the splicing template 1 are respectively provided at the transverse two ends of the splicing template 1. Sealing splicing pieces 13 respectively extend along the transverse two ends of the outer side surface of the splicing template 1. A sealing groove is formed between the sealing splicing pieces 13 and the outer side surface of the splicing template 1. The first slots 11 and the first insert blocks 12 between two adjacent splicing templates 1, and between the sealing splicing pieces 13 and the sealing groove can be inserted into each other. Through the above settings, multiple splicing templates 1 can be inserted into each other to form a closed loop.

[0059] Specifically, referring to Figure 7 As shown, in order to adjust the length of the splicing template 1, a fixed length adjuster 6 is further provided. The fixed length adjuster 6 includes an adjusting plate 61. Second slots 62 adapted to the first insert blocks 12 and second insert blocks 63 adapted to the first slots 11 are respectively provided at the transverse two ends of the adjusting plate 61, so as to realize the length adjustment of the splicing template 1 with a fixed length.

[0060] Specifically, referring to Figure 8As shown, when the length range of the splicing template 1 cannot be adjusted by the fixed-length adjuster 6, an adjustable-length adjuster 7 is also provided. The adjustable-length adjuster 7 includes at least two adjustment units 71. Each adjustment unit includes a first adjustment block 72 and a second adjustment block 73. A connecting spring 74 is provided between one lateral end of the first adjustment block 72 and one lateral end of the second adjustment block 73. On the other lateral end of the first adjustment block 72, there are third slots 721 respectively adapted to the first insert block 12 and the second insert block 63. On the other lateral end of the second adjustment block 73, there are third insert blocks 731 respectively adapted to the first slot 11 and the second slot 62. A telescopic connector 75 is connected between the longitudinal ends of the second adjustment blocks 73 in the two adjustment units. The telescopic connector 75 can flexibly allocate the number of adjusters for the length adjustment section and adapt to splicing sections of various lengths. When the length range of the splicing template 1 cannot be adjusted by the fixed-length adjuster 6, the length of the template can be adjusted through the connecting spring 74 at the assembly opening.

[0061] Specifically, the first slot 11, the second slot 62, and the third slot 721 are all concave circular structures, and the first insert block 12, the second insert block 63, and the third insert block 731 are convex circular structures.

[0062] Referring to Figures 9 - 12 As shown, since most water treatment structures are circular or rectangular, for a small number of structures with unconventional shapes, the following describes the case where the roundness fixer 2 bends the splicing template 1 from 0° to 135°. Any angle between 0 and 135° will not be specifically elaborated.

[0063] When the bending angle is 135°, due to the large bending angle, two shorter roundness adjustment rods 3 are needed for small-range adjustment and fixation; when the bending angle is 0°, since the bending angle is nearly in a straight state, two longer roundness adjustment rods 3 are needed for adjustment and fixation. The longer roundness adjustment rods 3 can be screwed in from the side of the connecting arm 22 close to the inner side of the splicing template 1. Embodiment 2

[0064] This embodiment takes the assembly of a circular water tank as an example to introduce the usage method of the general template in Embodiment 1.

[0065] The diameter of the circular water tank is 6 meters (inner diameter), the height is 3 meters, and the thickness of the pool wall is 0.3 meters. The length (lateral) of the splicing template 1 is 2 meters, the height (longitudinal) is 1 meter, and the thickness is 1.5 cm.

[0066] The inner circumference of the circular pool is about 18.84 meters, and the outer circumference is about 20.72 meters. A total of 9 universal splicing templates 1 are used, totaling 18 meters. Every 3 splicing templates 1 form a 6-meter-long template, leaving 3 gaps around. The length of the part that does not make up an integer can be adjusted by the fixed length adjuster 6 and the adjustable length adjuster 7.

[0067] The installation steps are as follows:

[0068] (1) Draw lines on the cushion layer, including the inner mold contour line and the outer mold contour line;

[0069] (2) Each three splicing templates 1 can be plugged into each other through the first slots 11 and the first plug-in blocks 12, and between the sealing splicing pieces 13 and the sealing grooves to form a closed annular structure;

[0070] (3) At the bottom 1 meter, place the assembled 6-meter universal splicing template 1 at the elastic line, adjust the roundness fixer 2 to ensure that the template will not deform, insert the insert block 26 of the roundness fixer 2 into the fixed insert of the fixed insert block 5 of the splicing template 1, and fix it by inserting the pin in the pin hole 52. Figure 13 Shown

[0071] (4) Installation of the length adjuster of the universal splicing template 1 at the joint

[0072] This embodiment is provided with three splicing interfaces, and only one installation is used for illustration, and the rest are similar.

[0073] Reference Figure 15 As shown, the joint interface is composed of a fixed length adjuster 6 and an adjustable length adjuster 7 which are plugged into each other, wherein the fixed length adjuster 6 is the main component with the largest number, and the adjustable length adjuster 7 is only provided at a small range where adjustment is required, and the non-fixed length is adjusted by connecting a spring 74, and the outer side of the inner mold (i.e., the side in contact with the concrete) is nested and sealed by a sealing assembly piece.

[0074] (5) Set up brackets and scaffolding, install the roundness fixture 2 of the previous layer and connect two adjacent roundness fixtures 2 through the connecting rod 4. After the roundness fixture 2 of the previous layer is fixed in position, screw the two rod bodies 41 into the adjacent roundness fixtures 2 corresponding to the bevel angle respectively, and put the sleeve 42 on one of the rod bodies 41. After aligning the two rod bodies 41 on the same straight line, put the sleeve 42 into the other rod body 41, and then rotate the adjustment ring 44 to abut against the two ends of the sleeve 42 to achieve fixed connection between the two rod bodies 41. Through the above arrangement, the connection between adjacent roundness fixtures 2 is enhanced, and the overall roundness can be better adjusted. The method of connecting all roundness fixtures 2 to each other is as described above.

[0075] (6) Reference Figure 14As shown, the first layer of inner mold is now installed. Starting from the first layer, first install the roundness fixture 2 connecting rod 4 on the roundness fixture 2 at the upper part of the first layer, and then install the universal splicing template 1 and the roundness fixture 2. The rest of the installation method is the same.

[0076] (7) The installation of the outer mold is the same as that of the inner mold. There is no need to install the roundness fixture 2 on the outside of the outer mold.

[0077] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
