Description

Technical Field

[0001] This utility model relates to the field of culvert wall casting technology, and more specifically, to a construction mold for continuous culvert wall casting. Background Technology

[0002] The culvert wall is the core load-bearing and protective component of the culvert structure. It primarily encloses the internal passageway, withstands soil lateral pressure and water flow impact, and also isolates external sediment, ensuring stable passage or drainage within the culvert. It is widely used in infrastructure construction such as highways, railways, and water conservancy projects. Because culverts are mostly located underground or beneath roadbeds, they are subjected to complex geological and hydrological environments over long periods. Their structural strength, sealing performance, and dimensional accuracy directly affect the overall safety and service life of the project. Therefore, culvert walls must be constructed using a pouring process to achieve a stable shape and reliable performance, ensuring the culvert meets long-term service requirements. There are two key problems in the existing culvert wall pouring construction: 1. Traditional molds lack precise adjustment and fixing structures, making it difficult to control the spacing between molds between culverts. Moreover, after the molds are positioned, they are prone to displacement during the pouring process due to insecure fixing, which in turn leads to quality problems such as uneven culvert wall thickness and appearance deformation. At the same time, the hoisting and installation of the molds rely on large hoisting equipment. The connection structure during disassembly and assembly is complex, the operation is difficult, and a lot of manpower is consumed, which seriously affects the convenience of construction and the stability of quality. 2. Traditional molds are mostly integral fixed structures. After the pouring of a section of culvert wall is completed, the mold needs to be disassembled, transported to the next construction position, and reassembled. This process is time-consuming, resulting in poor continuity of culvert wall pouring construction, low overall construction efficiency, and difficulty in meeting the needs of large-scale and high-efficiency infrastructure construction.

[0003] Therefore, there is an urgent need for continuous culvert wall casting construction molds to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a construction mold for continuous culvert wall casting, so as to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The formwork for continuous culvert wall casting includes guide rails and also includes: The base is slidably connected to the top wall of the guide rail and is symmetrically distributed about the guide rail; Support columns are evenly and fixedly connected to the top of the base; A crossbeam frame is fixedly connected to the top wall of the support column, and the crossbeam frame is connected to the templates through a hoisting assembly. The hoisting assembly is symmetrically distributed about the crossbeam frame, and the symmetrical templates are connected by evenly distributed connecting rods. Connection adjustment components, including: The side-rotating seat is fixedly connected to the side wall of the support column; Adjusting screw A is rotatably connected to the inner wall of the side rotating seat, and an adjusting cylinder is threadedly connected to the outer wall of the adjusting screw A; Adjusting screw B is threaded to the inner wall of the adjusting cylinder, and the thread direction of adjusting screw B is opposite to that of adjusting screw A; The limiting rod is slidably connected to the end of the adjusting screw B away from the adjusting cylinder; The docking component, located on the outer wall of the adjusting screw B, is used to connect the adjusting component and the template.

[0006] As a preferred technical solution of this application, the hoisting assembly includes: Lifting pulleys are installed on the outer wall of the crossbeam frame; The pull rope is wound around the outer wall of the hoisting pulley; A fixed pulley is connected to the end of the pull rope furthest from the hoisting pulley; The top rotating seat is rotatably connected to the outer wall of the fixed pulley, and the bottom of the top rotating seat is fixedly connected to the template.

[0007] As a preferred technical solution of this application, the docking component includes: A docking post is sleeved on the outer wall of the adjusting screw B, and the outer wall of the docking post is provided with limiting grooves symmetrically distributed about the docking post, and the limiting grooves cooperate with the limiting rod. The docking groove is formed on the outer wall of the docking column; Fixed screw B is uniformly fixed to the side wall of the template, and the fixed screw B is located on the inner wall of the docking groove.

[0008] As a preferred technical solution of this application, the outer wall of the template is fixedly connected with uniformly distributed fixing screws A, and the outer walls of both fixing screws A and fixing screws B are threadedly connected with fixing plates, and the side wall of the fixing plate abuts against the side wall of the docking column.

[0009] As a preferred technical solution of this application, a transverse connecting frame is provided between the template and the docking column, and the side wall of the transverse connecting frame abuts against the side wall of the fixing plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. The connection adjustment components enable precise adjustment of the template spacing. Combined with the positioning function of the limiting rod and limiting groove, and the reinforcement function of the fixing screws A and B and the fixing plate, this ensures that the template maintains stable verticality and positional accuracy throughout the pouring process. This effectively avoids problems such as uneven culvert wall thickness and appearance deformation caused by template offset, guaranteeing the quality of culvert wall pouring. Furthermore, the hoisting components simplify the template hoisting and installation process, eliminating the need for large and complex hoisting equipment. The simple connection between the docking components and the connection adjustment components, through limiting engagement and screw fixing, allows for easy disassembly by simply loosening the fixing plate and separating the limiting structure. This significantly reduces the operational difficulty for construction personnel, decreases labor costs, and achieves both precise quality control and convenient construction. It solves the problems of traditional molds, such as difficulty in controlling template spacing, unstable fixing leading to pouring offset and culvert wall quality issues, and the reliance on large equipment for template hoisting, which results in complex assembly and disassembly, difficult operation, high labor costs, and negatively impacts construction convenience and quality stability. 2. By using a mold with a sliding fit between the base and the guide rail, after pouring a section of the culvert wall, there is no need to disassemble the mold as a whole. Simply push the base along the guide rail to move it to the next construction section. This greatly reduces the time required for mold assembly and disassembly, effectively improving the continuity and overall efficiency of culvert wall pouring construction. It solves the problem that traditional molds in existing technologies are mostly fixed as a whole, requiring disassembly, transportation and reassembly after pouring a section, which is time-consuming, results in poor construction continuity and low efficiency, and makes it difficult to meet the needs of large-scale and efficient construction.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0014] like Figure 1-5 As shown, the continuous culvert wall casting mold proposed in this embodiment includes a guide rail 1, and further includes: The base 2 is slidably connected to the top wall of the guide rail 1 and is symmetrically distributed about the guide rail 1; Support columns 3 are evenly and fixedly connected to the top of base 2; The crossbeam frame 4 is fixedly connected to the top wall of the support column 3, and the crossbeam frame 4 is connected to the template 13 through the hoisting assembly. The hoisting assembly is symmetrically distributed about the crossbeam frame 4. The symmetrical templates 13 are connected by evenly distributed connecting rods 17. After all the templates 13 are installed and fixed, concrete is poured into the space between the symmetrical templates 13. After the concrete solidifies and reaches the required strength, the reverse operation is performed to separate the template 13 from the concrete, and the base 2 is pushed to slide along the guide rail 1 to move the mold as a whole to the next culvert wall pouring position. The above steps are repeated to achieve continuous pouring. Connection adjustment components, including: The side-rotating seat 5 is fixedly connected to the side wall of the support column 3; Adjusting screw A6 is rotatably connected to the inner wall of side rotating seat 5, and adjusting cylinder 7 is threadedly connected to the outer wall of adjusting screw A6; Adjusting screw B8 is threaded to the inner wall of adjusting cylinder 7, and the thread direction of adjusting screw B8 is opposite to that of adjusting screw A6; The limiting rod 9 is slidably connected to the end of the adjusting screw B8 away from the adjusting cylinder 7. After the position of the template 13 is initially determined, the spacing of the template 13 is adjusted by connecting the adjusting assembly. The adjusting cylinder 7 is rotated. Through the threaded engagement between the adjusting cylinder 7 and the adjusting screws A6 and B8, the adjusting screw A6 rotates and drives the adjusting cylinder 7 and the adjusting screw B8 to move relative to or towards each other, thereby changing the overall length of the adjusting assembly. At the same time, the limiting rod 9 at one end of the sliding adjusting screw B8 is made to engage with the limiting groove 11 on the outer wall of the docking column 10, thus completing the initial docking of the adjusting assembly and the docking assembly. The docking component is located on the outer wall of the adjusting screw B8 and is used to connect the adjusting component and the template 13.

[0015] like Figure 1 As shown, in a preferred embodiment, based on the above method, the hoisting assembly further includes: Lifting pulley 18 is installed on the outer wall of crossbeam frame 4; The pull rope 19 is wound around the outer wall of the hoisting pulley 18; Fixed pulley 21 is connected to the end of pull rope 19 away from lifting pulley 18; The top rotating seat 20 is rotatably connected to the outer wall of the fixed pulley 21, and the bottom of the top rotating seat 20 is fixedly connected to the template 13. The template 13 is hoisted by the crossbeam frame 4 fixed at the top of the support column 3 and the hoisting assembly installed on its outer wall. The pull rope 19 is wound around the hoisting pulley 18, and the end away from the hoisting pulley 18 is connected to the fixed pulley 21. The top rotating seat 20, which is rotatably connected to the outer wall of the fixed pulley 21, is fixed to the template 13. By controlling the opening and closing of the pull rope 19, the template 13 is hoisted to the preset pouring position.

[0016] like Figure 4-5 As shown, in a preferred embodiment, based on the above method, the docking component further includes: The docking post 10 is sleeved on the outer wall of the adjusting screw B8, and the outer wall of the docking post 10 is provided with limiting grooves 11 symmetrically distributed about the docking post 10, and the limiting grooves 11 cooperate with the limiting rod 9. The docking groove 12 is formed on the outer wall of the docking column 10; Fixed screws B15 are evenly fixed to the side wall of template 13, and fixed screws B15 are located on the inner wall of the docking groove 12. When the docking assembly is connected to template 13, the fixed screws B15 fixed to the side wall of template 13 are inserted into the docking groove 12 on the outer wall of docking column 10. Then, a fixing plate 16 is installed on the outer wall of fixed screws A14 on the outer wall of template 13, so that the side wall of fixing plate 16 abuts against the side wall of docking column 10. At the same time, in order to enhance the connection stability, a transverse connecting frame 22 is added between template 13 and docking column 10, and the side wall of transverse connecting frame 22 abuts against the side wall of fixing plate 16, so as to achieve a firm fixation between template 13 and docking assembly.

[0017] like Figure 4-5 As shown, in a preferred embodiment, based on the above method, the template 13 is further provided with uniformly distributed fixing screws A14 fixedly connected to its outer wall, and fixing plates 16 are threadedly connected to the outer walls of fixing screws A14 and B15, and the side wall of fixing plate 16 abuts against the side wall of docking column 10. The template 13 and docking assembly are firmly fixed by fixing screws A14 and B15.

[0018] like Figure 4-5 As shown, in a preferred embodiment, based on the above method, a transverse connecting frame 22 is further provided between the template 13 and the docking column 10, and the side wall of the transverse connecting frame 22 abuts against the side wall of the fixing plate 16. The addition of the transverse connecting frame 22 between the template 13 and the docking column 10, and the abutting of the side wall of the transverse connecting frame 22 against the side wall of the fixing plate 16, enhances the stability of the structural connection.

[0019] Specifically, when using this continuous culvert wall casting formwork: during the formwork assembly stage, first place the base 2 on the top wall of the guide rail 1 and adjust it to a symmetrical position about the guide rail 1 to complete the initial positioning of the base 2 and the guide rail 1; using the crossbeam frame 4 fixed at the top of the support column 3, the formwork 13 is hoisted through the hoisting assembly installed on its outer wall. The pull rope 19 is wound around the hoisting pulley 18, and its end away from the hoisting pulley 18 is connected to the fixed pulley 21. The top rotating seat 20 rotatably connected to the outer wall of the fixed pulley 21 is fixed to the formwork 13. By controlling the pulling rope 19, the formwork 13 is hoisted to the preset casting position; after the position of the formwork 13 is initially determined, the spacing of the formwork 13 is adjusted by connecting the adjustment assembly. Rotate the adjustment cylinder 7. Through the threaded engagement between the adjustment cylinder 7 and the adjustment screws A6 and B8, the rotation of the adjustment screw A6 will drive the adjustment cylinder 7 and the adjustment screw B8 to move relative to or towards each other, thereby changing the overall length of the adjustment assembly. At the same time, the limit of one end of the sliding adjustment screw B8 is limited. Positioning rod 9 is used to mate with the limiting groove 11 on the outer wall of the docking column 10, completing the initial docking of the adjustment component and the docking component. When the docking component is connected to the template 13, the fixing screw B15 fixed to the side wall of the template 13 is inserted into the docking groove 12 on the outer wall of the docking column 10. Then, fixing plate 16 is installed on the outer wall of fixing screw B15 and fixing screw A14 on the outer wall of the template 13, so that the side wall of fixing plate 16 abuts against the side wall of docking column 10. At the same time, in order to enhance the connection stability, a transverse connecting frame 22 is added between the template 13 and the docking column 10, and the side wall of transverse connecting frame 22 abuts against the side wall of fixing plate 16, so as to achieve a firm fixation of template 13 and docking component. After all templates 13 are installed and fixed, concrete is poured into the space between the symmetrical templates 13. After the concrete solidifies and reaches the required strength, the reverse operation is performed to separate the template 13 from the concrete, and the base 2 is pushed to slide along the guide rail 1, moving the mold as a whole to the next culvert wall pouring position. The above steps are repeated to achieve continuous pouring.

[0020] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
