Description

Technical Field

[0001] This utility model relates to the field of highway construction technology, and more specifically, to a highway construction template that is easy to install. Background Technology

[0002] During highway construction, to ensure the concrete pavement has precise width, thickness, and flatness, steel formwork is typically laid on both sides of the road to support and shape the poured concrete. Existing steel formwork for highway construction mostly adopts a segmented structure, with each formwork unit assembled on-site using bolts. Specifically, adjacent steel formwork sections have aligned connection holes at their ends. During installation, the two formwork sections are aligned, bolts are inserted sequentially, and nuts are tightened to secure them.

[0003] However, this traditional bolted connection method has many shortcomings. First, when facing large-scale highway construction, a large number of steel formwork panels need to be installed. The connection between each formwork panel requires multiple bolt insertion, alignment, and tightening operations. Frequent use of wrenches and other tools to tighten the bolts is labor-intensive, increases the workload of workers, and the whole process is cumbersome and time-consuming, resulting in low overall installation efficiency and making it difficult to meet the needs of rapid construction. Furthermore, relying solely on bolted connections to tighten the surface often results in poor sealing at the formwork joints, making it prone to grout leakage during concrete pouring. This not only wastes materials but also creates honeycomb defects or rough edges after demolding, affecting the appearance quality and structural integrity of the road surface.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a highway construction template that is easy to install, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A type of formwork for highway construction that is easy to install includes a steel formwork body. One end of the steel formwork body has a splicing groove, and the other end is connected to a positioning plate. The positioning plate cooperates with the splicing groove. Limiting grooves are opened on both sides of the splicing groove. Limiting plates are connected to both sides of the positioning plate. The limiting plates cooperate with the limiting grooves. A quick loading and unloading mechanism is provided on one side of the inner wall of the splicing groove. An expansion groove is opened on one side of the limiting groove. A sealing mechanism is provided inside the expansion groove.

[0008] Furthermore, in order to achieve rapid locking after the adjacent steel formwork bodies are spliced, the quick loading and unloading mechanism includes a shrinkage groove on one side of the splicing groove, a return spring connected to one side inside the shrinkage groove, a telescopic block connected to one end of the return spring, a pressure-bearing inclined surface on one side of the telescopic block, and the telescopic block is slidably installed in the shrinkage groove.

[0009] Furthermore, in order to improve the sealing effect when the steel formwork body is spliced, the sealing mechanism includes an extrusion plate that is slidably installed in the expansion groove. One side of the extrusion plate is connected to a sealing strip, and the other side is connected to a transmission inclined block. Limit strips are connected to both sides inside the expansion groove.

[0010] Furthermore, in order to achieve closed protection of the top of the splicing groove and the limiting groove after splicing, sliding grooves are opened on both sides of the top of the steel formwork body, and protective covers are slidably installed inside the sliding grooves.

[0011] Furthermore, in order to facilitate the fixing and embedding of the steel formwork body on both sides of the road, a support plate is provided on one side of the steel formwork body, and an insert plate is connected to the bottom surface of the support plate. A connecting groove is opened on the surface of the steel formwork body, and the connecting groove cooperates with the insert plate.

[0012] Furthermore, to facilitate the disassembly of the assembled steel template body, a transmission groove is opened at the top of the shrinkage groove, and a push rod is connected to the top of the telescopic block. The push rod is slidably installed in the transmission groove.

[0013] Furthermore, to facilitate the removal of the insert plate at the bottom of the support plate during demolding, a lifting ring is connected to the surface of the support plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Through the cooperation of positioning plates and splicing grooves, as well as limiting plates and limiting grooves, the two ends of adjacent steel formwork bodies can be quickly spliced. During splicing, the positioning plate is slidably pressed into the splicing groove. Through the quick loading and unloading mechanism, the positioning plate after splicing and installation is limited, thereby realizing the quick locking of adjacent formwork after splicing and installation. There is no need to repeatedly tighten multiple bolts, which greatly reduces the formwork assembly time and improves construction efficiency. It is especially suitable for large-scale, continuous highway projects and effectively reduces the labor intensity of workers.

[0016] 2. Through the sealing mechanism, when adjacent steel formwork bodies are connected to each other, the transmission inclined block is squeezed, causing the transmission inclined block to drive the extrusion plate to move to one side of the expansion groove. This allows the sealing strip in the expansion groove to tightly adhere to one end of the steel formwork body it is splicing with after being compressed, effectively improving the sealing effect of the splicing gap, preventing concrete slurry from leaking from the joint, and ensuring the forming quality of the concrete road edge.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] According to an embodiment of the present invention, a template for highway construction that is easy to install is provided.

[0031] Example 1:

[0032] like Figures 1-7 As shown, a highway construction template that is easy to install according to an embodiment of the present invention includes a steel template body 1. One end of the steel template body 1 has a splicing groove 2, and the other end is connected to a positioning plate 3. The positioning plate 3 cooperates with the splicing groove 2. Limiting grooves 4 are opened on both sides of the splicing groove 2. Limiting plates 5 are connected to both sides of the positioning plate 3. The limiting plates 5 cooperate with the limiting grooves 4. When adjacent steel template bodies 1 need to be installed and connected, the positioning plate 3 and the limiting plates 5 on both sides are slidably installed in the splicing groove 2 and the limiting grooves 4, so as to realize the quick splicing of two steel template bodies 1. A quick loading and unloading mechanism 6 is provided on one side of the inner wall of the splicing groove 2, which is used to lock the two steel template bodies 1 after splicing to make them securely connected. A telescopic groove 7 is opened on one side of the limiting groove 4, and a sealing mechanism 8 is provided inside the telescopic groove 7, which is used to improve the sealing of the connection gap after the two steel template bodies 1 are spliced.

[0033] like Figures 1-9As shown, the quick loading and unloading mechanism 6 includes a shrinkage groove 601 on one side of the splicing groove 2. A return spring 602 is connected to one side of the shrinkage groove 601. One end of the return spring 602 is connected to a telescopic block 603. A pressure-receiving slope 604 is provided on one side of the telescopic block 603. The telescopic block 603 is slidably installed in the shrinkage groove 601. When the positioning plates 3 at one end of two adjacent steel template bodies 1 are installed in the splicing groove 2, pressing down on the positioning plates 3 can cause the sliding positioning plates 3 to press the pressure-receiving slope 604 on one side of the telescopic block 603, pushing the telescopic block 603 to slide into the shrinkage groove 601. When the positioning plates 3 are fully installed in the splicing groove 2... When the top of the positioning plate 3 passes through the contraction groove 601, the return spring 602 can quickly push the telescopic block 603 back to its original position through its own elastic force, thus limiting the top of the installed positioning plate 3 and achieving rapid locking after the two steel template bodies 1 are spliced ​​together. The sealing mechanism 8 includes a pressing plate 801 that is slidably installed in the telescopic groove 7. One side of the pressing plate 801 is connected to a sealing strip 802, and the other side is connected to a transmission inclined block 803. Limiting strips 804 are connected to both sides inside the telescopic groove 7. When the positioning plate 3 is slidably installed into the splicing groove 2, it can press and push the transmission inclined block 803, causing the transmission inclined block 803 to push the pressing plate 801. The expansion joint moves to one side of the expansion groove 7, causing the extrusion plate 801 to press the sealing strip 802 on one side to one end of the steel formwork body 1 to be spliced ​​with it, achieving a sealed fit and improving the sealing effect of the splicing gap; the top two sides of the steel formwork body 1 have sliding grooves 9, and protective covers 10 are slidably installed inside the sliding grooves 9. When two steel formwork bodies 1 are spliced ​​and installed, the protective covers 10 are installed in the sliding grooves 9, which can seal and protect the top of the splicing groove 2 and the limiting groove 4, preventing concrete from entering the grooves during pouring; a support plate 11 is provided on one side of the steel formwork body 1, and an insert plate 12 is connected to the bottom surface of the support plate 11. The surface of the support plate 11 has a connecting groove 13, which cooperates with the insert plate 12 to facilitate the fixed insertion of the steel template body 1 on both sides of the road; the top of the shrinkage groove 601 has a transmission groove 14, and the top of the telescopic block 603 is connected to a push rod 15. The push rod 15 is slidably installed in the transmission groove 14. When disassembling the two connected steel template bodies 1, the push rod 15 causes the telescopic block 603 to slide back into the shrinkage groove 601, which facilitates the sliding of the positioning plate 3 out of the splicing groove 2; the surface of the support plate 11 is connected to a lifting ring 16, which is used to easily pull out the insert plate 12 at the bottom of the support plate 11 when disassembling the formwork.

[0034] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0035] In summary, with the help of the above-mentioned technical solution of this utility model, in actual use, when splicing and installing steel formwork, firstly, align the positioning plate 3 at one end of a steel formwork body 1 with the splicing groove 2 at the other end of the adjacent steel formwork body 1, and align the limiting plates 5 on both sides of the positioning plate 3 with the limiting groove 4. Then, slide the positioning plate 3 and the limiting plates 5 into the direction of the splicing groove 2 and the limiting groove 4. During the insertion process, the lower surface of the positioning plate 3 gradually presses the pressure inclined surface 604 on one side of the telescopic block 603, forcing the telescopic block 603 to overcome the elastic force of the return spring 602 and retract into the contraction groove 601; at the same time, the side wall of the rear part of the positioning plate 3 will also push the transmission inclined block 803 in the sealing mechanism 8, causing it to slide along the limiting strip 804, driving the extrusion plate 801 to move towards one side of the telescopic groove 7, thereby pushing the sealing strip 802 connected to the extrusion plate 801 outward and tightly pressing it against the side of the adjacent formwork end, realizing the pre-compression seal at the joint. When the positioning plate 3 is fully inserted into the splicing groove 2 and its top passes through the contraction groove 601, the return spring 602 loses external pressure and immediately releases its elastic potential energy, pushing the telescopic block 603 to quickly return to its original position, causing it to protrude into the contraction groove 601. This locks the top of the positioning plate 3, effectively limiting its position and completing the rapid locking between the two steel template bodies 1 without the need for bolt tightening. At this time, the sealing strip 802 is continuously pressed and adhered under the action of the transmission inclined block 803, effectively filling the splicing gap between the templates and significantly improving the sealing performance of the connection, preventing grout leakage during concrete pouring. When the template needs to be removed after construction, the push rod 15 in the transmission groove 14 is pushed manually or with a tool to retract the telescopic block 603 back into the contraction groove 601, releasing the limitation on the top of the positioning plate 3. Then, the positioning plate 3 can be easily slid out of the splicing groove 2, achieving rapid separation of the steel template.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
