Description

Technical Field

[0001] The present invention relates to the technical field of bridge engineering, in particular to a special-shaped bridge template and a manufacturing method thereof. Background Art

[0002] Due to the different topography, construction requirements, planning and design institutes, and design styles of different design masters in the process of bridge construction, the concrete columns, beams, and various auxiliary structures in bridge construction are different, especially some special bridge structures, which require very different structures. This requires that the forming molds of these concrete components must also adapt to these changes and requirements. However, there is no unified national standard for existing bridge formwork. The formwork design is now a typical non-standard design. Different types of products cannot be used interchangeably and cannot be recycled. In order to ensure the flatness, smoothness, and easy demoulding of the formwork surface, most existing formworks use larger overall structures, which take up a lot of space and affect transportation. Therefore, this application provides special-shaped bridge formwork and its manufacturing method to meet the needs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a special-shaped bridge template and a manufacturing method thereof to solve the problems that different types of existing templates are not interchangeable, cannot be recycled, and occupy a large volume, which affects transportation.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0005] A special-shaped bridge template comprises a plurality of base plates and auxiliary connection units for connecting the base plates, wherein the auxiliary connection units are used to fix two adjacent base plates together;

[0006] The auxiliary connecting unit includes a first tooth groove opened on both sides of the substrate, and the two adjacent substrates are meshed and connected through the first tooth groove, and through holes are opened on both sides of the substrate near the first tooth groove, and a connecting shaft is inserted in the through hole, and the two connecting shafts on the two adjacent substrates are fixedly connected with the same connecting block, and a limiting rod is provided between the two first tooth grooves that are meshed with each other, and a second tooth groove is opened on the limiting rod, and the second tooth groove is respectively meshed and connected with the two first tooth grooves, and one end of the limiting rod is fixedly connected to a mounting plate, and a plurality of through threaded holes are opened on the substrate, and screws are threadedly connected in the threaded holes. An iron sheet is provided on one side of the substrate, and a plurality of threaded sleeves are fixedly connected to the iron sheet, and the threaded sleeves are inserted in the threaded holes, and one end of the screw passes through the threaded hole and is threadedly connected to the threaded sleeve.

[0007] Preferably, a handle is fixedly connected to the mounting plate.

[0008] Preferably, a mark is provided on a side of the mounting plate corresponding to the handle.

[0009] Preferably, the substrate includes flat plates and curved plates, and a plurality of flat plates are connected to form a planar structure or a polygonal column structure, and a plurality of curved plates are connected to form a cylindrical structure.

[0010] Preferably, the number of the screws and the number of the threaded sleeves are both several, and the number of the screws and the number of the threaded sleeves are the same.

[0011] Preferably, the connecting shaft and the connecting block are connected via threads.

[0012] A method for manufacturing a special-shaped bridge template includes the following steps: first, selecting a template, and selecting a corresponding base plate according to the shape of the special-shaped bridge pier column;

[0013] Step 2: Assemble the base plates. Connect multiple base plates according to the pier shape to form a polygonal column or cylindrical structure with two through ends, which is used to adapt to the shape of the special-shaped bridge pier. Engage the first tooth grooves between two adjacent base plates. Then insert the connecting shaft into the through hole. Connect the two adjacent connecting shafts through the connecting block. Then rotate the two adjacent base plates to achieve the appropriate rotation angle and adapt to the shape of the special-shaped bridge pier. Finally, connect the first and last base plates through the connecting shaft and the connecting block to form a polygonal column or cylindrical structure.

[0014] Step 3: Fix the limit. After the base plate is assembled, use the handle to insert the limit rod between each of the two mutually meshed first tooth grooves, push the limit rod until the mounting plate contacts the top of the base plate, and the second tooth groove on the limit rod engages with the two first tooth grooves respectively to form a limit structure to prevent the two adjacent base plates from rotating, thereby achieving fixed positioning after the base plate assembly is assembled;

[0015] Step 4: Install the iron sheet, then bend the iron sheet into a polygonal columnar structure or cylindrical structure surrounded by multiple substrates in step 2, then insert the multiple threaded sleeves of the iron sheet into the corresponding threaded holes, and fix the substrate and the iron sheet with screws to ensure that the iron sheet fits tightly to the inner wall of the polygonal columnar structure or cylindrical structure, and ensures the flatness and smoothness of the inner wall of the polygonal columnar structure or cylindrical structure. In this way, the assembly and preparation of the special-shaped bridge formwork structure are completed. When in use, concrete is poured into the polygonal columnar structure or cylindrical structure surrounded by the substrate, and the quality of the concrete after forming is ensured by fitting the iron sheet to the concrete.

[0016] Preferably, in step 1, when it is a polygonal column pier structure, a flat plate is selected, and when it is a cylindrical structure, an arcuate plate is selected, and appropriate flat plates and arcuate plates are selected according to corresponding identifications.

[0017] Preferably, in step 4, after the iron sheet is bent into a polygonal columnar structure or a cylindrical structure that fits the substrate, the head and tail connection positions of the iron sheet are welded.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] In the above scheme, by setting up auxiliary connection units and using them in conjunction with multiple base plates, a modular structure is formed. Different template structures can be assembled according to different shapes of special-shaped bridges, thereby improving the versatility of the template and making it recyclable. After disassembly, it can be stacked to reduce space occupancy and facilitate transportation.

[0020] Multiple base plates are fixedly connected by auxiliary connection units to form a modular splicing structure, so that the multiple base plates are surrounded by stable polygonal column structures and cylindrical structures, which can be adapted to piers of different shapes and improve practicality. Iron sheets are arranged on the inner walls of the polygonal column structure and the cylindrical structure, and the iron sheets are bonded to the concrete to ensure the smoothness and flatness of the concrete molding, improve the quality of the piers, and improve practicality. At the same time, only the iron sheets of the template structure cannot be recycled, and the other structures can be modularly assembled and disassembled and recycled. After the concrete is poured, when it is not completely solidified, the structure except the iron sheets can be dismantled, and the dismantled structure and the new iron sheet structure can be assembled into a new pier template structure. Under limited cost, the progress of bridge construction is improved and the practicality is further improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] like Figure 1As shown, an embodiment of the present invention provides a special-shaped bridge formwork, including multiple substrates 1 and auxiliary connection units 2 connected between the multiple substrates 1, the auxiliary connection unit 2 is used to fix the connection between two adjacent substrates 1, and through the setting of the auxiliary connection unit 2, it is used in conjunction with the multiple substrates 1 to form a modular structure. It can be assembled into different template structures according to special-shaped bridges of different shapes, thereby improving the versatility of the template, being recyclable, and being stackable after disassembly, thereby reducing space occupancy and facilitating transportation.

[0040] like Figure 1-11 As shown, the auxiliary connection unit 2 includes a first tooth groove 3 provided on both sides of the base plate 1, and the two adjacent base plates 1 are meshed and connected through the first tooth groove 3. A through hole 4 is provided on both sides of the base plate 1 near the first tooth groove 3, and a connecting shaft 5 is inserted into the through hole 4. The two connecting shafts 5 on the two adjacent base plates 1 are fixedly connected with the same connecting block 6. The connecting shaft 5 and the connecting block 6 are connected by a thread. A limiting rod 7 is provided between the two first tooth grooves 3 that are meshed with each other. A second tooth groove 8 is provided on the limiting rod 7, and the second tooth groove 8 is respectively meshed and connected with the two first tooth grooves 3. One end of the limiting rod 7 is fixedly connected to a mounting plate 9, and a handle is fixedly connected to the mounting plate 9 10. A logo 11 is provided on one side of the mounting plate 9 corresponding to the handle 10. A plurality of through threaded holes are provided on the base plate 1, and screws 12 are threadedly connected to the threaded holes. An iron sheet 13 is provided on one side of the base plate 1, and a plurality of threaded sleeves 14 are fixedly connected to the iron sheet 13, and the threaded sleeves 14 are inserted into the threaded holes. One end of the screw 12 passes through the threaded hole and is threadedly connected to the threaded sleeve 14. The number of screws 12 and threaded sleeves 14 is several, and the number of screws 12 and threaded sleeves 14 is the same. The base plate 1 includes a flat plate 15 and an arc-shaped plate 16. A planar structure or a polygonal columnar structure is formed by connecting a plurality of flat plates 15, and a cylindrical structure is formed by connecting a plurality of arc-shaped plates 16.

[0041] The multiple base plates 1 are fixedly connected by the auxiliary connection unit 2, so that the multiple base plates 1 form a stable polygonal column structure and a cylindrical structure, which can be adapted to piers of different shapes and improve practicality. The iron sheet 13 is set on the inner wall of the polygonal column structure and the cylindrical structure, and the iron sheet 13 is fitted with the concrete to ensure the smoothness and flatness of the concrete molding, improve the quality of the pier and improve practicality. At the same time, only the iron sheet 13 of the template structure cannot be recycled, and the other structures can be modularly assembled and disassembled and can be recycled. After the concrete is poured, when it is not completely solidified, the structure except the iron sheet 13 can be dismantled, and the dismantled structure and the new iron sheet 13 structure can be assembled into a new pier template structure. Under limited cost, the progress of bridge construction is improved and the practicality is further improved.

[0042] like Figure 12As shown, a method for manufacturing a special-shaped bridge formwork includes the following steps: 1. Formwork selection: selecting a corresponding base plate 1 according to the shape of the special-shaped bridge pier column to form a polygonal column structure or a cylindrical structure with two ends connected, which is used to adapt to the shape of the special-shaped bridge pier column; when it is a polygonal column pier structure, selecting a flat plate 15; when it is a cylindrical structure, selecting a curved plate 16; selecting appropriate flat plates 15 and curved plates 16 according to corresponding identifiers 11; and combining multiple flat plates 15 with auxiliary connecting units 2 to form planar formwork structures of different sizes and polygonal column structures of different sizes; and combining multiple curved plates 16 with auxiliary connecting units 2 to form cylindrical structures of different sizes. This improves the adaptability of the formwork, facilitates recycling, and has high practicality;

[0043] Step 2: Assemble the base plates. Connect multiple base plates 1 according to the shape of the pier column. Engage the first tooth grooves 3 between two adjacent base plates 1. Then insert the connecting shaft 5 into the through hole 4. Connect the two adjacent connecting shafts 5 via the connecting block 6. Then rotate the two adjacent base plates 1 to a suitable angle to match the shape of the special-shaped pier column. Finally, connect the first and last base plates 1 via the connecting shaft 5 and the connecting block 6 to form a polygonal column structure or a cylindrical structure. The combination of multiple base plates 1 to form a polygonal column structure or a cylindrical structure with two connected ends and four closed sides can be used to manufacture pier columns of different sizes and shapes.

[0044] Step 3: Fixed limit. After the assembly of the base plate 1 is completed, the limit rod 7 is inserted into the position between each of the two mutually meshed first tooth grooves 3 through the handle 10, and the limit rod 7 is pushed until the mounting plate 9 conflicts with the top of the base plate 1. The second tooth grooves 8 on the limit rod 7 are respectively engaged with the two first tooth grooves 3 to form a limit structure to prevent the two adjacent base plates 1 from rotating, thereby achieving the fixed positioning of the base plates 1 after assembly. The polygonal column structure or cylindrical structure surrounded by the base plates 1 is used for shaping and fixing, providing greater support force for the later concrete pouring to prevent the concrete from expanding and causing deformation of the combined formwork;

[0045] Step 4, the iron sheet is installed, and then the iron sheet 13 is bent into a polygonal columnar structure or cylindrical structure surrounded by multiple substrates 1 in step 2, and then the multiple threaded sleeves 14 of the iron sheet 13 are inserted into the corresponding threaded holes, and the substrate 1 and the iron sheet 13 are fixed by screws 12 to ensure that the iron sheet 13 is tightly fitted to the inner wall of the polygonal columnar structure or cylindrical structure, and the flatness and smoothness of the inner wall of the polygonal columnar structure or cylindrical structure are ensured. When the iron sheet 13 is bent into a polygonal columnar structure or cylindrical structure that fits the substrate 1, the head and tail connection positions of the iron sheet 13 are welded to complete the assembly preparation of the special-shaped bridge formwork structure. When in use, concrete is poured into the polygonal columnar structure or cylindrical structure surrounded by the substrate 1, and the quality of the concrete after molding is ensured by fitting the iron sheet 13 with the concrete. By setting the iron sheet 13, only the iron sheet 13 is in contact with the concrete, which can ensure the flatness and smoothness of the pier column, and is conducive to mold opening and convenient to use.

[0046] The present invention encompasses any alternatives, modifications, equivalents, and solutions that fall within the spirit and scope of the present invention. To provide a thorough understanding of the present invention, specific details are described in detail below in connection with the preferred embodiments of the present invention, but those skilled in the art will be able to fully understand the present invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.
