Description
Technical Field
[0001] This application relates to the field of building technology, and in particular to a concrete formwork for road surface overhaul. Background Technology
[0002] Currently, when installing concrete formwork, construction workers generally first fix one concrete formwork to the ground, then place another concrete formwork next to it. Next, they measure the height of the two formworks and compare the results to determine if the height difference is within acceptable limits. Then, they drill threaded holes at corresponding positions on the two formworks and use bolts and nuts to secure them. Finally, they pour concrete into the gap between the two formworks, and then install and fix multiple concrete formworks in sequence.
[0003] However, when installing concrete formwork, construction workers need to drill threaded holes in the concrete formwork and then use bolts and nuts to fix the two concrete formworks. This is labor-intensive for construction workers, and the angle between the two concrete formworks cannot be adjusted in the existing technology. In actual road repair projects, the inability to adjust the angle of the concrete formwork makes it difficult to match the actual terrain, resulting in difficulties in formwork installation and inability to accurately pour concrete according to design requirements, which affects the construction progress and quality. Utility Model Content
[0004] To address the issue of using bolts and nuts to fix concrete formwork and the inability to adjust the angle of the concrete formwork, this application provides a concrete formwork for road surface repair.
[0005] This application provides a concrete formwork for road surface overhaul using the following technical solution:
[0006] A concrete formwork for road surface repair includes a formwork body one and a formwork body two.
[0007] Both template body one and template body two are provided with a connection mechanism for template connection;
[0008] An auxiliary mechanism for adjusting the angle between the two templates is provided between the template body one and the template body two;
[0009] The template body one and template body two are connected end-to-end with the auxiliary mechanism through a connecting mechanism.
[0010] By adopting the above technical solution, template body one and template body two constitute the template body, which directly contacts the concrete and determines the geometric accuracy of the forming surface. The connecting mechanism is used to realize the reliable connection between template body one and template body two, ensuring the stability and sealing of the overall template structure during concrete pouring. The auxiliary mechanism is mainly used to adjust and fix the angle between template body one and template body two to meet the needs of different road surface overhaul projects.
[0011] Preferably, a fixing column is fixedly connected to the top surface of the template body one, a foaming strip is fixedly provided on the side of the template body one away from the fixing column, and a sliding groove is provided on both sides of the template body one, with a sealing strip inserted into the inside of the sliding groove.
[0012] By adopting the above technical solution, the arc-shaped groove of the fixed column and the auxiliary plate cooperate to achieve guiding positioning during angle adjustment. The foam strip is used to contact the road surface to prevent grout leakage. The sliding groove is used to insert the sealing strip and keep the sealing strip fixed. The sealing strip is used to prevent concrete from seeping into the interior of the connecting mechanism.
[0013] Preferably, the connecting mechanism includes a splicing block one fixedly connected to the template body one near the fixed column, an auxiliary groove is provided through one side of the surface of the splicing block one, and a baffle is fixedly connected inside the auxiliary groove.
[0014] By adopting the above technical solution, splicing block one is fixed on template body one and template body two, serving as the core component for connection. It cooperates with splicing block two to provide an installation base for other connecting components, achieving the initial docking of the two templates. The auxiliary groove provides installation space for internal components such as half gears, and the baffle acts as a limit to prevent the foam strip from entering the auxiliary groove during movement, ensuring the stability of the structure.
[0015] Preferably, the top of the splicing block one is provided with a circular hole one, both ends of the splicing block one are fixedly connected with snap-fit blocks, and the inner circumference of the auxiliary groove is provided with a plurality of insertion holes one.
[0016] By adopting the above technical solution, the first round hole is used to insert the rotating shaft, providing a basis for adjusting the angle between the two templates. The snap-fit block is compatible with the rotating disk. When the templates are connected, the rotating disk and the snap-fit block cooperate with each other, increasing the contact area and friction of the connection, improving the stability and reliability of the connection, and preventing the templates from loosening during the concrete pouring process. The first insertion hole is used to fix the angle between the two templates, preventing them from shifting after the angle is confirmed.
[0017] Preferably, a second splicing block is fixedly connected to the side of the template body away from the first splicing block. A second circular hole is opened through the top of the second splicing block. A rotating shaft is inserted into the second circular hole and the first circular hole. A second insertion hole is symmetrically opened on the top of the second splicing block. A rotating disk adapted to the insertion of the snap-fit block is symmetrically rotatably connected inside the second splicing block. A connecting post adapted to the insertion of the second insertion hole is fixed on the top of the rotating shaft.
[0018] By adopting the above technical solution, after the two templates are connected, the relative positions of the two templates are further fixed by inserting the rotating shaft into the second round hole and the inside of the snap-fit block, which enhances the overall stability of the templates. The stability of the rotating shaft is ensured by inserting the connecting post into the second insertion hole.
[0019] Preferably, the top surface of the second splicing block is provided with an auxiliary plate, and the outer surface of the auxiliary plate is provided with an arc-shaped groove that is adapted to the sliding of the fixed column.
[0020] By adopting the above technical solution, when adjusting the template angle, the fixed column slides in the arc groove, which plays an auxiliary positioning and guiding role, making the angle adjustment more accurate and smooth.
[0021] Preferably, the auxiliary mechanism includes a fixing plate 1 fixedly connected to the inner wall of the splicing block 1, and the fixing plate 1 is located inside the baffle and the auxiliary groove. A half gear 1 is fixedly connected to the side of the fixing plate 1 away from the splicing block 1. The fixing plate 2 is fixedly connected to the side of the splicing block 2 close to the splicing block 1. A half gear 2 that meshes with the half gear 1 is fixedly provided on the side of the fixing plate 2 close to the splicing block 1, and the half gear 2 is located inside the baffle and the auxiliary groove.
[0022] By adopting the above technical solution, fixing plate one and fixing plate two provide installation bases for half gear one and half gear two, respectively, to ensure stable installation and operation of the gears. Through the meshing transmission of the two half gears, when one of the templates is rotated, the other template can be driven to rotate relative to it, thereby realizing precise adjustment of the angle between the two templates.
[0023] Preferably, both ends of the second half gear and the first half gear are hinged with connecting plates, the rotating shaft is inserted through the inside of the second half gear, and the inside of the first half gear has a plug that is compatible with the insertion hole.
[0024] By adopting the above technical solution, the connecting plate serves to connect and support the two half gears, keeping them in a relatively stable position during transmission, while allowing the half gears to rotate to ensure smooth transmission. The rotating shaft provides the rotation axis for the second half gear, ensuring that the second half gear can rotate smoothly and achieve meshing transmission with the first half gear, thereby adjusting the template angle. The insert is used to lock the meshing position of the two half gears, further fixing the angle between the two templates, preventing the angle from changing during the pouring process, and ensuring the accuracy and quality of concrete pouring.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] 1. By using the rotating disc and the snap-fit block in conjunction, the contact area and friction of the connection are increased, which improves the stability and reliability of the connection and prevents the formwork from loosening during the concrete pouring process. Furthermore, by inserting the connecting column into the second insertion hole, the relative position of the two formworks is further fixed, which enhances the overall stability of the formwork.
[0027] 2. By utilizing the meshing transmission of half-gear one and half-gear two, rotating one template can drive the other template to rotate relative to it, thereby achieving precise adjustment of the angle between the two templates. The fixed column slides in the arc groove, playing an auxiliary positioning and guiding role, making the angle adjustment more accurate and smooth. Furthermore, by using the rotating shaft to insert into the round hole two and the snap-fit block, the splicing block two can rotate relative to the splicing block one around the rotating shaft, providing a basis for adjusting the angle between the two templates.

[0036] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.
[0037] This application discloses a concrete formwork for road surface overhaul.
[0038] Reference Figure 1 , Figure 2 A concrete formwork for road surface repair includes a formwork body 1 and a formwork body 2. The formwork body 1 and the formwork body 2 are made of the same material, shape and size. The formwork body 1 and the formwork body 2 are connected end to end to an auxiliary mechanism through a connecting mechanism. The top left side of the formwork body 1 is fixedly connected to a fixed column 3. One side of the formwork body 1 is fixedly attached to a foam strip 5. The foam strip 5 is located on the side away from the fixed column 3 and is made of ethylene propylene diene monomer (EPDM) rubber foam strip to ensure the sealing of the side of the formwork in contact with the road surface. The two ends of one side of the formwork body 1 are provided with grooves 4, which are T-shaped and used to insert sealing strips 6 and ensure that the sealing strips 6 will not fall off. The inner wall of the grooves 4 is adapted to the sealing strips 6, and the sealing strips 6 are thermoplastic elastomer (TPE) sealing strips.
[0039] During use, workers fix the foam strip 5 to the bottom of the concrete formwork using polyurethane structural adhesive. Then, the formwork body 1 and formwork body 2 are connected end to end through the connecting mechanism and auxiliary mechanism. The sealing strip 6 is inserted into the groove 4 that is close to the formwork body 1 and formwork body 2, and the sealing strip 6 ensures that the connection between the formwork body 1 and formwork body 2 is sealed.
[0040] Reference Figure 3 , Figure 4Both sides of the template body 1 and template body 2 are fixedly connected with connecting mechanisms. The connecting mechanisms include splicing block 71, which is fixedly connected to one side of template body 1 by welding. The splicing block 71 is located on the side closer to the fixed column 3. The side of the splicing block 71 away from template body 1 is circumferential to facilitate the adjustment of the template angle. An auxiliary groove 73 is opened through one side of the outer surface of the middle part of the splicing block 71. The inner wall of the auxiliary groove 73 is fixedly connected to the baffle 74. A rectangular groove is opened on the side of the baffle 74 away from the baffle 74 to facilitate the adjustment of the angle between the templates after the template is installed. A round hole 76 is opened on the top of the splicing block 71, and the round hole 76 is located on the side away from template body 1. Both ends of the splicing block 71 are fixedly connected to the snap-fit block 77. Several insertion holes 75 are opened on the circumference of the bottom surface of the inner wall of the auxiliary groove 73.
[0041] When in use, align the splicing block 71 of template body 2 with the splicing block 72 of template body 1 to connect the ends of template body 1 and template body 2. Then, align the snap-fit block 77 with the position of the rotating disk 710 and ensure that the snap-fit block 77 can be inserted into the interior of the rotating disk 710.
[0042] One side of the template body 1 is fixedly connected to the splicing block 2 72 by welding. The side of the splicing block 2 72 away from the template body 1 is circumferentially shaped. The splicing block 2 72 is located on the side away from the splicing block 1 71. A circular hole 2 79 is formed through the center of the top surface of the splicing block 2 72.

The rotating shaft 712 is inserted into the interior of the splicing block 1 71 and the splicing block 2 72. A socket 2 78 is symmetrically formed on the top surface of the splicing block 2 72. The depth of the socket 2 78 is above the rotating disk 710, so it will not affect the rotation of the rotating disk 710. 8 is located on both sides of the second round hole 79. The inner wall of the second splicing block 72 is rotatably connected to the rotating disk 710. The rotating disk 710 is located on the upper and lower sides of the inner wall of the second splicing block 72. The rotating disk 710 is plugged into the snap-fit block 77. The top arc surface of the rotating shaft 712 is fixedly connected to the connecting column 713. The connecting column 713 is plugged into the second insertion hole 78. The top surface of the second splicing block 72 is snapped into the auxiliary plate 711. The auxiliary plate 711 has a slot hole 1 inside that is plugged into the rotating shaft 712 and the connecting column 713. The outer surface of the auxiliary plate 711 has an arc groove 714. The arc groove 714 is slidably adapted to the fixed column 3.
[0043] As described above, the splicing block 71 of template body 2 is aligned with the splicing block 72 of template body 1, the snap-fit block 77 is inserted into the rotating disk 710, and the round hole 79 is aligned with the round hole 76. Then, the auxiliary plate 711 is placed on the top surface of the splicing block 72, and the fixing post 3 is located inside the arc groove 714. The slot hole 1 of the auxiliary plate 711 is aligned with the insertion hole 78 and the round hole 79. Then, the rotating shaft 712 is inserted into the insertion hole 78 and the round hole 79 through the slot hole 1 of the auxiliary plate 711, thereby fixing the auxiliary plate 711 on the top surface of the splicing block 72, thus completing the connection between template body 1 and template body 2.
[0044] Reference Figure 5 An auxiliary mechanism is fixed between template body 1 and template body 2. The auxiliary mechanism includes a fixing plate 81 fixedly connected to the middle of the inner wall of splicing block 71 by bolts. The fixing plate 81 is located inside the baffle 74 and the auxiliary groove 73. One side of the fixing plate 81 is fixedly connected to a half gear 82, which is located away from splicing block 71. One side of splicing block 72 is fixedly connected to fixing plate 86 by bolts. The fixing plate 86 is located on the side closer to splicing block 71. Half gear 2 84 is fixed on one side, and half gear 2 84 is located on the side close to splicing block 1 71. Half gear 2 84 meshes with half gear 1 82, and half gear 2 84 and half gear 1 82 are located inside baffle 74 and auxiliary groove 73. Both ends of half gear 2 84 and half gear 1 82 are hinged to connecting plate 83. The inner wall of half gear 2 84 is provided with slot 2 that is adapted to be inserted into shaft 712. The center of half gear 1 82 is inserted through post 87, and post 87 is adapted to be inserted into hole 1 75.
[0045] As described above, after aligning and connecting splicing block 1 71 with splicing block 2 72, the worker fixes fixing plate 1 81 to the middle of the inner wall of splicing block 1 71 with bolts. Then, fixing plate 2 86 is fixed to the side of splicing block 2 72 near splicing block 1 71 with bolts, and fixing plate 2 86 is parallel to fixing plate 1 81, and the slot 2 of half gear 2 84 is aligned with the round hole 2 79 to ensure that the rotating shaft 712 can be inserted into the slot 2. After installation, the worker pulls the insert post 87 upward to prevent the insert post 87 from being inserted into the insert hole 1 75. Then, according to the needs, the template body 2 2 is pushed. After being pushed to the required angle, the insert post 87 is inserted into the insert hole 1 75 to ensure the fixation of the template body 2 2, thereby achieving angle adjustment.
[0046] The implementation principle of a concrete formwork for road surface overhaul in this application embodiment is as follows:
[0047] During use, workers fix the foam strip 5 to the bottom surface of the concrete formwork using polyurethane structural adhesive. Then, they align the snap-fit block 77 of the formwork body 2 with the rotating disk 710 of the formwork body 1 and insert it, ensuring that the second round hole 79 coincides with the first round hole 76. Next, they fix the first fixing plate 81 and the second fixing plate 86 to the inner walls of the splicing block 2 72 and the splicing block 1 71 using bolts, ensuring that the second fixing plate 86 is parallel to the first fixing plate 81 and that the slot 2 of the half-gear 2 84 coincides with the second round hole 79. Then, they place the auxiliary plate 711 on the top surface of the splicing block 2 72, positioning the fixing post 3 inside the arc groove 714, with the slot 1 of the auxiliary plate 711 coinciding with the insertion hole 78 and the second round hole 79. Finally, they insert the rotating shaft 712 through the slot 1 of the auxiliary plate 711 into the insertion hole 78, the second round hole 79, and the slot 2. The auxiliary plate 711 is fixed to the top surface of the splicing block 72, thus completing the connection between the template body 1 and the template body 2. The template body 1 and the template body 2 are connected end to end, and the rotating shaft 712 provides the rotation axis for the half gear 84, ensuring that the half gear 84 can rotate smoothly and realize the meshing transmission with the half gear 82, thereby adjusting the template angle. Then, the sealing strip 6 is inserted into the sliding groove 4 near the template body 1 and the template body 2, and the sealing strip 6 ensures that the connection between the template body 1 and the template body 2 is in a sealed state. After the installation is completed, the staff pulls the insert post 87 upward to prevent the insert post 87 from being inserted into the insertion hole 75. Then, according to the needs, the template body 2 is pushed. After being pushed to the required angle, the insert post 87 is inserted into the insertion hole 75 to ensure the fixation of the template body 2, thereby realizing the angle adjustment.
