Abstract
Description
Technical Field
[0001] The invention relates to the technical field of building construction, in particular to a road and bridge template. Background Art
[0002] In road and bridge construction, the formwork is one of the key components to ensure the accuracy of the structure shape and surface quality. In order to improve the rigidity and durability of the formwork, reinforcement ribs are usually installed on the back of the formwork. In the existing reinforcement rib design, most of them are one-piece components arranged along the long side of the formwork, while along the wide side, they are composed of multiple steel plates spliced together. The connection between these steel plates is mainly achieved by welding. Specifically, not only the steel plates need to be welded in the horizontal direction, but also additional welding operations need to be performed in the vertical direction to ensure the stability of the structure.
[0003] However, during the welding process in the vertical direction (the so-called "vertical welding"), the change in the material properties of the welding heat-affected zone can easily lead to prestress inside the steel plate. The existence of this prestress, especially in large formworks, may cause structural deformation, which in turn affects the overall flatness of the formwork. Therefore, in order to eliminate these prestresses, the existing reinforcement ribs usually need to be tempered after welding to remove the internal stress generated during the welding process. Although this method can solve the problem to a certain extent, it increases production costs and process complexity, and also prolongs the production cycle. Summary of the invention
[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a road and bridge template, which can improve the strength and rigidity of the template as a whole.
[0005] In addition, the present invention also provides a method for manufacturing a road and bridge template.
[0006] A road and bridge formwork according to an embodiment of the first aspect of the present invention comprises: a panel, one side of the panel being a casting surface and the other side being a reinforcement surface; A reinforcement component is arranged on the reinforcement surface, and the reinforcement component includes a transverse reinforcement rib, a vertical reinforcement rib and a rectangular outer frame. The transverse reinforcement rib is provided with a first bite portion, and the vertical reinforcement rib is provided with a second bite portion. The first bite portion and the second bite portion are adapted to each other. The rectangular outer frame is provided with a plurality of connecting holes. The two ends of the transverse reinforcement rib are abutted against the rectangular outer frame, and the two ends of the vertical reinforcement rib are abutted against the rectangular outer frame. The rectangular outer frame is provided with a plurality of connecting holes, and the connecting holes are arranged to avoid the transverse reinforcement rib and the vertical reinforcement rib.
[0007] A road and bridge formwork according to an embodiment of the present invention has at least the following beneficial effects: the prestress problem caused by heat treatment in the traditional welding process is effectively avoided through the bite design between the transverse reinforcing ribs and the vertical reinforcing ribs. This design reduces the risk of material deformation at high temperatures and ensures the dimensional accuracy and structural integrity of the formwork; the mutual bite and welding connection of the transverse reinforcing ribs and the vertical reinforcing ribs form a solid grid structure, which significantly improves the overall rigidity and stability of the formwork. This stable design not only enhances the ability of the formwork to withstand external pressure, but also ensures that the formwork will not deform or shift during the pouring process; the design allows the use of a robotic arm to efficiently weld the transverse reinforcing ribs and the vertical reinforcing ribs. Automated welding not only greatly improves production efficiency, but also ensures the consistency of welding quality, reduces quality fluctuations caused by human factors, and improves product reliability; the leveling process before and after welding and the optimization of the bite design ensure the flatness of the formwork in large sizes, and even in large projects, it can meet high standards and provide a more uniform and flat casting surface, thereby improving the quality of the project.
[0008] According to some embodiments of the present invention, the first engaging portion includes a first slot and a second slot, the first slot and the second slot are extended toward the panel, a connecting plate is provided between the first slot and the second slot, the second engaging portion is provided with a third slot and a fourth slot, the transverse reinforcing rib is clamped to the vertical reinforcing rib through the second engaging portion, and the vertical reinforcing rib is clamped to the transverse reinforcing rib through the first engaging portion. The cooperation of the first slot, the second slot and the third slot, the fourth slot ensures that the transverse reinforcing rib and the vertical reinforcing rib can be accurately clamped together, which not only improves the installation accuracy, but also ensures the close cooperation between the components, and reduces the problems caused by position deviation.
[0009] According to some embodiments of the present invention, the top of the connecting plate is provided with an arc transition treatment. The arc transition treatment simplifies the assembly process between the transverse reinforcement ribs and the vertical reinforcement ribs, making the clamping operation smoother and more stable. This design helps to improve the assembly accuracy, ensure that each component can be accurately aligned and fixed, and reduce installation errors.
[0010] According to some embodiments of the present invention, the depth of the first slot and the height of the transverse reinforcing rib are A, satisfying 0.4≤A≤0.6, and the depth of the second slot and the height of the vertical reinforcing rib are B, satisfying 0.4≤B≤0.6. The matching design of the slot depth and the reinforcing rib height within the proportional range ensures the firmness of the connection while avoiding the damage to the structural integrity of the reinforcing rib caused by the slot being too deep or too shallow. This not only enhances the overall rigidity and stability of the formwork system, but also effectively prevents local deformation or fracture caused by stress concentration.
[0011] According to some embodiments of the present invention, the vertical reinforcing ribs are clamped to the roots of the first slot and the second slot, and the transverse reinforcing ribs are clamped to the roots of the third slot and the fourth slot. The design of clamping to the slot roots enables stress to be effectively transferred from the reinforcing ribs to the panel, reducing local stress concentration, thereby improving the durability and reliability of the entire system. This design helps to evenly distribute external loads and prevent material fatigue and deformation caused by stress concentration.
[0012] According to some embodiments of the present invention, the widths of the first slot and the second slot are adapted to the thickness of the vertical reinforcing rib, and the widths of the third slot and the fourth slot are adapted to the thickness of the transverse reinforcing rib. This design enables the reinforcing rib to be fully embedded in the corresponding slot, significantly enhancing the overall rigidity and pressure resistance of the formwork system. This design not only improves the ability of the formwork to withstand external pressure, but also prevents deformation or displacement caused by loose connections.
[0013] According to some embodiments of the present invention, the transverse reinforcing rib and the vertical reinforcing rib are square tubes, the transverse reinforcing rib is provided with four first bite parts, and the four first bite parts are arranged at intervals along the extension direction of the transverse reinforcing rib, and the vertical reinforcing rib is provided with four second bite parts, and the four second bite parts are arranged at intervals along the extension direction of the vertical reinforcing rib. The design of multiple bite parts increases the number of contact points between the transverse reinforcing rib and the vertical reinforcing rib, and significantly enhances the connection strength. Each bite part can provide additional support and fixation, ensure the close fit between the reinforcing ribs, prevent loosening or displacement, and improve the overall performance of the formwork system.
[0014] According to some embodiments of the present invention, the first bite portion is provided with two first grooves, and the two first grooves are respectively arranged opposite to the side walls of the transverse reinforcement rib, the first bite portion is provided with two second grooves, and the two second grooves are respectively arranged opposite to the side walls of the transverse reinforcement rib, the second bite portion is provided with two third grooves, and the two third grooves are respectively arranged opposite to the side walls of the vertical reinforcement rib, and the second bite portion is provided with two fourth grooves, and the two fourth grooves are respectively arranged opposite to the side walls of the vertical reinforcement rib.
[0015] According to some embodiments of the present invention, the transverse reinforcing ribs and the vertical reinforcing ribs are in a tic-tac-toe structure. A stable grid-like frame is formed by staggered transverse reinforcing ribs and vertical reinforcing ribs, which significantly improves the overall rigidity and compressive resistance of the formwork system. The tic-tac-toe structure can effectively resist external loads and ensure that the formwork will not deform or shift during construction.
[0016] The method for making a road and bridge template according to the second embodiment of the present invention includes the road and bridge template according to the first embodiment of the present invention, and the specific steps are as follows: a. Cutting: using a cutting machine, cut the entire square tube into the required lengths of the transverse reinforcement ribs and the vertical reinforcement ribs, process the first bite portion on the transverse reinforcement ribs, and process the second bite portion on the vertical reinforcement ribs; b. Molding, aligning the first bite portion and the second bite portion, inserting the vertical reinforcement rib into the transverse reinforcement rib, and welding the transverse reinforcement rib and the vertical reinforcement rib together using vertical welding, and then installing the welded transverse reinforcement rib and the vertical reinforcement rib together with the rectangular outer frame; c. Leveling: put the welded reinforcement components into the leveling machine for leveling; d. Final assembly: fit the reinforcement components to the reinforcement surface of the panel, fix the reinforcement components and the panel by welding, and complete the assembly of the entire road and bridge formwork.
[0017] According to the method for making a road and bridge formwork according to the second embodiment of the present invention, there are at least the following beneficial effects: by aligning the first bite portion and the second bite portion, inserting the vertical reinforcement rib into the transverse reinforcement rib, and then using the vertical welding process to firmly weld them together, a stable well-shaped structure is formed. This design not only enhances the strength of the connection part, but also ensures the close fit between the transverse reinforcement rib and the vertical reinforcement rib to prevent loosening or displacement, greatly improving the overall stability and reliability of the formwork system; the reinforcement component is installed separately, and there is no need to perform vertical welding on the panel. This design avoids the influence of thermal stress on the panel caused by high temperature during welding, and significantly reduces the deformation of the panel. In the traditional method, welding directly on the panel may cause uneven heating of the panel locally, thereby causing warping or distortion, while this method effectively avoids these problems by concentrating the welding process on the reinforcement component; due to the reduction of the influence of welding on the panel, the panel can maintain a higher flatness, which not only improves the surface quality of the concrete after pouring, but also reduces the workload of subsequent finishing. The high-flatness panel ensures the stability of the formwork system during construction and improves the quality standard of the final project.

The transverse reinforcement rib 110 is provided with a first bite portion 160, and the vertical reinforcement rib 120 is provided with a second bite portion 170. The first bite portion 160 and the second bite portion 170 are adapted to each other. The rectangular outer frame 130 is provided with a plurality of connecting holes 200. The two ends of the transverse reinforcement rib 110 abut against the rectangular outer frame 130, and the two ends of the vertical reinforcement rib 120 abut against the rectangular outer frame 130. The rectangular outer frame 130 is provided with a plurality of connecting holes 200, and the connecting holes 200 are arranged to avoid the transverse reinforcement rib 110 and the vertical reinforcement rib 120.
[0026] The interlocking design between the transverse reinforcing ribs 110 and the vertical reinforcing ribs 120 effectively avoids the prestressing problem caused by heat treatment in the traditional welding process. This design reduces the risk of material deformation at high temperatures and ensures the dimensional accuracy and structural integrity of the template. The interlocking and welding connection between the transverse reinforcing ribs 110 and the vertical reinforcing ribs 120 forms a solid grid structure, which significantly improves the overall rigidity and stability of the template. This stable design not only enhances the ability of the template to withstand external pressure, but also ensures that the template will not deform or shift during the pouring process. The design allows the use of a robotic arm to efficiently weld the transverse reinforcing ribs 110 and the vertical reinforcing ribs 120. Automated welding not only greatly improves production efficiency, but also ensures the consistency of welding quality, reduces quality fluctuations caused by human factors, and improves product reliability. The leveling process before and after welding and the optimization of the interlocking design ensure the flatness of the template in large sizes. Even in large projects, it can meet high standards and provide a more uniform and flat casting surface, thereby improving the quality of the project.
[0027] The first engaging portion 160 includes a first slot 130 and a second slot 140, the first slot 130 and the second slot 140 are extended toward the panel 100, a connecting plate 150 is arranged between the first slot 130 and the second slot 140, the second engaging portion 170 is provided with a third slot 180 and a fourth slot 190, the transverse reinforcing rib 110 is clamped to the vertical reinforcing rib 120 through the second engaging portion 170, and the vertical reinforcing rib 120 is clamped to the transverse reinforcing rib 110 through the first engaging portion 160. The cooperation of the first slot 130, the second slot 140 and the third slot 180, the fourth slot 190 ensures that the transverse reinforcing rib 110 and the vertical reinforcing rib 120 can be clamped together accurately, which not only improves the installation accuracy, but also ensures the close cooperation between the components, and reduces the problems caused by position deviation.
[0028] The top of the connecting plate 150 is provided with an arc transition treatment. The arc transition treatment simplifies the assembly process between the transverse reinforcing ribs 110 and the vertical reinforcing ribs 120, making the clamping operation smoother and more stable. This design helps to improve the assembly accuracy, ensure that each component can be accurately aligned and fixed, and reduce installation errors.
[0029] The depth of the first slot 130 and the height of the transverse reinforcing rib 110 are A, satisfying 0.4≤A≤0.6, and the depth of the second slot 140 and the height of the vertical reinforcing rib 120 are B, satisfying 0.4≤B≤0.6. The matching design of the slot depth and the reinforcing rib height within the proportional range ensures the firmness of the connection while avoiding the damage to the structural integrity of the reinforcing rib caused by the slot being too deep or too shallow. This not only enhances the overall rigidity and stability of the formwork system, but also effectively prevents local deformation or fracture caused by stress concentration.
[0030] The vertical reinforcing rib 120 is clamped at the root of the first slot 130 and the second slot 140, and the transverse reinforcing rib 110 is clamped at the root of the third slot 180 and the fourth slot 190. The design of clamping at the root of the slot enables the stress to be effectively transferred from the reinforcing rib to the panel 100, reducing local stress concentration, thereby improving the durability and reliability of the entire system. This design helps to evenly distribute external loads and prevent material fatigue and deformation caused by stress concentration.
[0031] The widths of the first slot 130 and the second slot 140 are adapted to the thickness of the vertical reinforcing rib 120, and the widths of the third slot 180 and the fourth slot 190 are adapted to the thickness of the transverse reinforcing rib 110. This design enables the reinforcing ribs to be fully embedded in the corresponding slots, significantly enhancing the overall rigidity and pressure resistance of the formwork system. This design not only improves the ability of the formwork to withstand external pressure, but also prevents deformation or displacement caused by loose connections.
[0032] The transverse reinforcing rib 110 and the vertical reinforcing rib 120 are square tubes. The transverse reinforcing rib 110 is provided with four first bite parts 160, which are arranged at intervals along the extension direction of the transverse reinforcing rib 110. The vertical reinforcing rib 120 is provided with four second bite parts 170, which are arranged at intervals along the extension direction of the vertical reinforcing rib 120. The design of multiple bite parts increases the number of contact points between the transverse reinforcing rib 110 and the vertical reinforcing rib 120, significantly enhancing the connection strength. Each bite part can provide additional support and fixation, ensuring the close fit between the reinforcing ribs, preventing loosening or displacement, and improving the overall performance of the formwork system.
[0033] The first bite portion 160 is provided with two first grooves 130, and the two first grooves 130 are respectively arranged on the side walls of the transverse reinforcement rib 110; the first bite portion 160 is provided with two second grooves 140, and the two second grooves 140 are respectively arranged on the side walls of the transverse reinforcement rib 110; the second bite portion 170 is provided with two third grooves 180, and the two third grooves 180 are respectively arranged on the side walls of the vertical reinforcement rib 120; the second bite portion 170 is provided with two fourth grooves 190, and the two fourth grooves 190 are respectively arranged on the side walls of the vertical reinforcement rib 120.
[0034] The transverse reinforcing ribs 110 and the vertical reinforcing ribs 120 are arranged in a tic-tac-toe pattern. The staggered arrangement of the transverse reinforcing ribs 110 and the vertical reinforcing ribs 120 forms a stable grid-like frame, which significantly improves the overall rigidity and compressive strength of the formwork system. The tic-tac-toe pattern can effectively resist external loads and ensure that the formwork will not deform or shift during construction.
[0035] This embodiment provides a formwork system for road and bridge construction, which aims to improve the overall rigidity, assembly convenience and casting quality of the formwork through optimized structural design. The formwork is particularly suitable for concrete pouring projects, which can ensure high-quality construction results and extend service life. One side of the panel 100 is used as a casting surface, directly in contact with concrete, and is made of high-strength material to ensure that it can withstand greater pressure during the pouring process. The other side of the panel 100 is a reinforced surface, which is provided with a reinforcement component to enhance the overall rigidity and stability of the formwork.
[0036] The reinforcement assembly is arranged on the reinforcement surface of the panel 100, and specifically includes the following parts: the transverse reinforcement rib 110 is made of a square tube to ensure that it has sufficient compressive and bending strength. Each transverse reinforcement rib 110 is provided with four first bite portions 160, which are spaced apart along the extension direction thereof. Each first bite portion 160 includes two first slots 130 arranged opposite to each other and two second slots 140 arranged opposite to each other, which are used for clamping with the vertical reinforcement rib 120.
[0037] The vertical reinforcing ribs 120 are also made of square tubes to ensure their structural strength. Each vertical reinforcing rib 120 is provided with four second bite portions 170, which are spaced apart along the extending direction thereof. Each second bite portion 170 includes two third slots 180 arranged opposite to each other and two fourth slots 190 arranged opposite to each other, which are used for clamping with the transverse reinforcing rib 110.
[0038] The rectangular outer frame 130 is in contact with both ends of the transverse reinforcing ribs 110 and the vertical reinforcing ribs 120, and is provided with a plurality of connection holes 200. These connection holes 200 avoid the positions of the transverse reinforcing ribs 110 and the vertical reinforcing ribs 120 to ensure the flexibility and stability of the connection, while avoiding damage to the structural integrity of the reinforcing ribs. The first bite portion 160 of the transverse reinforcing ribs 110 and the second bite portion 170 of the vertical reinforcing ribs 120 are adapted to each other to form a solid well-shaped structure. This design not only enhances the connection strength, but also reduces stress concentration, thereby improving the overall stability and durability of the formwork system.
[0039] The top of the connecting plate 150 disposed between the first slot 130 and the second slot 140 is subjected to arc transition treatment, which optimizes stress distribution, reduces the risk of local stress concentration, and improves the reliability and durability of the connection part. The transverse reinforcing ribs 110 and the vertical reinforcing ribs 120 are arranged in a tic-tac-toe structure to form a stable grid-like frame. This layout significantly improves the overall rigidity and compressive resistance of the formwork system, ensuring that no deformation or displacement occurs during the construction process.
[0040] This design can reduce the deformation of the panel 100, strengthen the separate installation of components, eliminate the need for vertical welding on the panel 100, avoid the influence of welding thermal stress on the panel 100, significantly reduce the deformation of the panel 100, and improve the flatness of the panel 100. The high-precision slotting and bite design ensures the close fit between the components, reduces installation errors, ensures the overall consistency and stability of the formwork system, and improves the quality standards of the final project. The modular design makes the assembly process simple and fast, saves time and labor costs, and improves construction efficiency.
[0041] The method for making a road and bridge template according to the second embodiment of the present invention includes the road and bridge template according to the first embodiment of the present invention, and the specific steps are as follows: a. Cutting: using a cutting machine, cut the entire square tube into the required lengths of the transverse reinforcing ribs 110 and the vertical reinforcing ribs 120, and process the first bite portion 160 on the transverse reinforcing ribs 110 and the second bite portion 170 on the vertical reinforcing ribs 120; b. Molding, aligning the first bite portion 160 and the second bite portion 170, and then inserting the vertical reinforcing rib 120 into the transverse reinforcing rib 110, and welding the transverse reinforcing rib 110 and the vertical reinforcing rib 120 together using vertical welding, and then installing the welded transverse reinforcing rib 110 and the vertical reinforcing rib 120 together with the rectangular outer frame 130; c. Leveling: put the welded reinforcement components into the leveling machine for leveling; d. Final assembly: fit the reinforcement component to the reinforcement surface of the panel 100, fix the reinforcement component and the panel 100 by welding, and complete the assembly of the entire road and bridge formwork.
[0042] The method for making a road and bridge formwork according to the second embodiment of the present invention has at least the following beneficial effects: by aligning the first bite portion 160 and the second bite portion 170, plugging the vertical reinforcing rib 120 into the transverse reinforcing rib 110, and then firmly welding them together using a vertical welding process, a stable tic-tac-toe structure is formed. This design not only enhances the strength of the connection part, but also ensures the tight fit between the transverse reinforcing rib 110 and the vertical reinforcing rib 120, prevents loosening or displacement, and greatly improves the overall stability and reliability of the formwork system; the reinforcing components are installed separately, and there is no need to perform vertical welding operations on the panel 100. This design avoids the thermal stress caused by high temperature during welding on the panel 100, and significantly reduces the deformation of the panel 100. In the traditional method, welding directly on the panel 100 may cause uneven heating of the panel 100, which in turn causes warping or distortion. This method effectively avoids these problems by concentrating the welding process on the reinforcement components. Since the impact of welding on the panel 100 is reduced, the panel 100 can maintain a higher flatness, which not only improves the surface quality of the concrete after pouring, but also reduces the workload of subsequent finishing. The high-flatness panel 100 ensures the stability of the formwork system during construction and improves the quality standard of the final project.
[0043] In the second aspect of the present invention, a method for manufacturing a road and bridge formwork is provided, which is intended to ensure high quality and high efficiency production of the formwork system through accurate cutting, reliable connection, fine leveling and efficient assembly. This method is applicable to the road and bridge formwork of the first aspect of the present invention.
[0044] First, high-strength square tubes are selected as the raw materials for the transverse reinforcing ribs 110 and the vertical reinforcing ribs 120, and a high-precision cutting machine is used to accurately cut the entire square tube into the required length to ensure that the size is accurate. Four first bite parts 160 are processed on the transverse reinforcing ribs 110, each of which includes two first slots 130 arranged opposite to each other and two second slots 140 arranged opposite to each other. Four second bite parts 170 are processed on the vertical reinforcing ribs 120, each of which includes two third slots 180 arranged opposite to each other and two fourth slots 190 arranged opposite to each other. High-precision cutting and processing improves material utilization and reduces waste generation. Accurate size control provides a solid foundation for subsequent assembly and ensures the adaptability between various components.
[0045] The processed first bite portion 160 and the second bite portion 170 are accurately aligned to ensure that the transverse reinforcement rib 110 and the vertical reinforcement rib 120 can be smoothly snapped in. Insert the vertical reinforcement rib 120 into the first bite portion 160 of the transverse reinforcement rib 110 so that the two fit tightly. Use the vertical welding process to firmly weld the transverse reinforcement rib 110 and the vertical reinforcement rib 120 together to form a stable tic-tac-toe structure. Assemble the welded transverse reinforcement rib 110 and vertical reinforcement rib 120 assembly with the rectangular outer frame 130 to form a complete reinforcement assembly to ensure that the connection between all components is tight and stable. The reliable bite design and vertical welding process enhance the strength of the connection part to prevent loosening or displacement. The tic-tac-toe structure significantly improves the overall rigidity and stability of the formwork system and adapts to complex construction environments.
[0046] Place the welded reinforcement components into the leveling machine for fine leveling. Through the leveling operation, ensure that all components are in the same plane, improve the overall flatness of the formwork, and fine leveling ensures the surface quality of the concrete after pouring and reduces the workload of subsequent finishing. Improve the flatness and stability of the formwork system and ensure reliability and consistency during the construction process.
[0047] The leveled reinforcement assembly is installed separately on the reinforcement surface of the panel 100, and there is no need to perform vertical welding on the panel 100. The reinforcement assembly and the panel 100 are fixed by horizontal welding, which avoids the influence of the thermal stress of the vertical welding on the panel 100, reduces the risk of deformation of the panel 100, and improves the flatness of the panel 100.
[0048] This welding method can not only realize automated welding through robots and support batch prefabrication, but also specially optimizes the welding process: horizontal welding is used between the reinforcement component and the panel 100 to ensure the stability of the connection; and when assembling the reinforcement component, split vertical welding is used to avoid vertical welding operations directly on the panel 100, thereby effectively preventing deformation of the panel 100 caused by vertical welding and ensuring the flatness of the panel 100.
[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
