Description

Technical Field

[0001] This utility model belongs to the technical field of road and bridge preforming equipment, specifically relating to a self-propelled hydraulic T-beam prefabrication template. Background Technology

[0002] T-beams are a common type of reinforced concrete or prestressed concrete beam structure, named for their cross-sectional shape resembling the capital letter "T". This structural form is widely used in bridge engineering and building structures. In the construction of precast T-beams, traditional methods involve multiple hoistings of the side formwork using a gantry crane to splice together sufficient length to ensure the T-beam is formed in one go. This assembly process is time-consuming and labor-intensive. Similarly, during manual demolding after forming, the lack of control over manual operation easily damages the surface and corners of the T-beam, affecting the beam's appearance and reducing the durability of the concrete. Utility Model Content

[0003] In view of this, the present invention provides a self-hydraulic T-beam prefabrication template, which is equipped with multiple sets of side template units. Each set of side template units can move on linear guide rails on both sides of the platform to complete the length splicing of the outer mold on the side of the T-beam. At the same time, each set of side template units is equipped with a hydraulic unit to adjust the position of the side template. Based on the movement of the moving parts and the hydraulic parts, the present invention eliminates the need for manual hoisting when splicing and dismantling the side templates, thereby improving the efficiency of T-beam preparation and avoiding accidental bumps caused by manual operation.

[0004] To achieve the above-mentioned technical objectives, the specific technical solution adopted by this utility model is as follows:

[0005] A self-propelled hydraulic T-beam prefabrication formwork includes:

[0008] The upper template is the outer mold for forming the top of the T-beam;

[0009] The end template is the outer mold for forming the axial end of the T-beam;

[0010] Wherein: each of the side template units adjusts its position based on the moving part, and each of the side templates adjusts its posture based on each of the hydraulic parts, and then the side templates are brought together to form the outer mold of the two sides of the T-beam.

[0011] Furthermore, to provide operating space, the pedestal and the linear guide rail are based on the same set of foundation supports, and the horizontal height of the linear guide rail is lower than the upper surface of the pedestal.

[0012] Furthermore, in order to improve the stability of the side template unit, each side of the platform is provided with two linear guide rails, and the two linear guide rails on a single side include a first linear guide rail and a second linear guide rail.

[0013] The moving part includes:

[0014] The first walking unit is located on the side of the side template unit away from the platform. It moves linearly along the first linear guide rail based on motor drive and includes at least two moving wheels that are connected to the first linear guide rail.

[0015] The second traveling unit, driven by a motor, moves linearly along a second linear guide rail and includes at least two moving wheels that are coupled to the second linear guide rail.

[0016] Furthermore, the self-propelled hydraulic T-beam prefabrication formwork also includes:

[0017] A crossbeam, perpendicular to the first linear guide rail and parallel to the upper surface of the platform, connects the first traveling unit and the second traveling unit.

[0018] A sliding body is slidably mounted on the crossbeam.

[0019] Furthermore, in order to achieve pose adjustment, the hydraulic unit includes:

[0020] A transverse hydraulic cylinder, with its base mounted on the first traveling unit, and the end of its actuating rod connected to the sliding body;

[0021] A vertical hydraulic cylinder is perpendicular to the upper surface of the platform, with its base mounted on the sliding body, and the end of its actuating rod acting on the side template.

[0022] Furthermore, in order to achieve reliable posture adjustment, there are two sets of vertical cylinders, and the two sets of vertical cylinders are arranged in parallel; the ends of the two actuating rods of the two sets of vertical cylinders are respectively connected to the two flanges of the H-shaped steel frame;

[0023] The H-beam is fixedly connected to the side template, and its flange is parallel to the axial direction of the T-beam.

[0024] Furthermore, in order to improve the load resistance of the side template unit, the base of the transverse hydraulic cylinder is rotatably mounted on the first traveling unit, with the rotating shaft parallel to the first linear guide rail.

[0025] Furthermore, in order to improve the operational stability of the side template unit, the first traveling unit is set in the first housing; the bottom of the first housing is provided with two limiting edges; the two limiting edges are respectively set on both sides of the first linear guide rail to prevent the first traveling unit from derailing;

[0026] The second traveling unit is housed in the second housing; the bottom of the second housing is provided with two limiting edges, which are respectively located on both sides of the second linear guide rail to prevent the second traveling unit from derailing.

[0027] Furthermore, to accommodate the fabrication of various T-beams, the side formwork can be replaced.

[0028] Furthermore, to improve the stability of vertical pose adjustment, the number of crossbeams is two sets.

[0029] By adopting the above technical solution, this utility model can bring the following beneficial effects:

[0034] 5. The axial consistency of the side template of this utility model is achieved based on the track. Therefore, this utility model only needs to be equipped with two vertical hydraulic cylinders and one horizontal hydraulic cylinder to make the position and posture of the side template meet the predetermined requirements.

[0035] 6.

[0050] In one embodiment of this utility model, a self-hydraulic T-beam prefabrication formwork is provided, such as... Figure 1 As shown, it includes:

[0051] The platform 1 has a lower template 4 on its upper surface for placing the T-beam, and parallel linear guide rails on both sides.

[0052] Multiple sets of side template units 2 are arranged in pairs opposite each other on both sides of the base 1; the side template unit 2 includes a moving part, a hydraulic part and a side template 29; the moving part moves along a linear guide rail, and the hydraulic part is installed on the moving part to adjust the position of the side template 29;

[0053] The upper template 3 is the outer mold for forming the top of the T-beam. According to the forming requirements of the T-beam, the existing conventional upper template 3 can be used, or it can be obtained by splicing the top of two side templates 29.

[0054] The end template is the outer mold for forming the axial ends of the T-beam. Existing end templates are used according to the forming requirements of the T-beam.

[0055] Among them: each side template unit 2 adjusts its position based on the motion part, and each side template 29 adjusts its posture based on each hydraulic part, and then each side template 29 is brought together to form the outer mold of the two sides of the T-beam.

[0056] In this embodiment, the pedestal 1 protrudes upward from the foundation to provide operating space for other equipment and personnel on both sides. Its upper surface is flat, and the lower template 4 (bottom forming outer mold) of the T-beam is fixed on this flat surface. Figure 2 As shown, in this embodiment, multiple side template units 2 are provided on both sides of the pedestal 1, and multiple side templates 29 are used to adapt to the forming length of the T-beam. After the multiple side template units 2 are spliced ​​on both sides of the pedestal 1, they form an integral mold for the side of the preformed T-beam. End templates are installed at both ends of the spliced ​​multiple side templates 29.

[0057] The arrangement method of this embodiment is as follows: multiple side template units 2 move sequentially to their respective positions based on linear guide rails, and the movement of the hydraulic unit causes each side template 29 to be spliced. After the upper template 3 is pressed on, the end templates are used to seal the cavity, forming the entire T-beam's casting cavity.

[0058] The separation method in this embodiment is as follows: the side template 29 is separated from the cast T-beam based on the motion unit, and then the side template unit 2 is moved along the linear guide rail. Based on the movement of the motion unit and the hydraulic unit, this invention eliminates the need for manual hoisting when splicing and dismantling the side template 29, improving the efficiency of T-beam preparation while avoiding accidental bumps caused by manual operation.

[0059] In this embodiment, in order to provide operating space, such as Figure 1 As shown, the pedestal 1 and the linear guide rail are based on the same set of foundation supports, and the horizontal height of the linear guide rail is lower than the upper surface of the pedestal 1.

[0060] In this embodiment, the side formwork unit 2 is driven by hydraulics or a motor, eliminating the need for crane assembly and disassembly, thus significantly shortening the construction cycle for a single span. In the prefabrication yard, the side formwork unit 2 of this invention automatically moves to the next work station, reducing intermittent waiting time. This invention is particularly suitable for long-line prefabrication, where the formwork can move span by span along the track, matching large-scale T-beam production. This embodiment reduces mechanical dependence: it eliminates the need for frequent use of cranes, forklifts, and other equipment, reducing rental and manual operation costs. This embodiment uses linear guide rails for coarse positioning and hydraulic components for position adjustment, resulting in small errors in the side formwork 29 and ensuring the dimensional consistency of the T-beams.

[0061] In this embodiment, as Figure 1 , 2 As shown, in order to improve the stability of the side template unit 2, each side of the platform 1 is provided with two linear guide rails. The two linear guide rails on a single side include the first linear guide rail 5 and the second linear guide rail 6.

[0062] like Figure 3 , 4 As shown, the moving part includes:

[0063] The first walking unit 21 is located on the side of the side template unit 2 away from the platform 1. It moves linearly along the first linear guide rail 5 based on motor drive and includes at least two moving wheels that are connected to the first linear guide rail 5.

[0064] The second walking unit 22, driven by a motor, moves linearly along the second linear guide rail 6 and includes at least two moving wheels that are coupled to the second linear guide rail 6.

[0065] In this embodiment, the first walking unit 21 and the second walking unit 22 are electrically driven platform wheels. The wheels are engaged with the track and can be track wheels (similar to train wheels).

[0066] In some embodiments, the first walking unit 21 and the second walking unit 22 may be driven by hydraulic motors, and the power of the hydraulic unit may be unified.

[0067] In this embodiment, the self-propelled hydraulic T-beam prefabrication formwork further includes:

[0068] The crossbeam 23 is perpendicular to the first linear guide rail 5 and parallel to the upper surface of the platform 1, connecting the first traveling unit 21 and the second traveling unit 22.

[0069] The sliding body 24 is slidably mounted on the crossbeam 23.

[0070] In this embodiment, the crossbeam 23 is rectangular, and its upper surface is finely cleaned to reduce the coefficient of friction. The bottom of the sliding body 24 is fitted with the crossbeam 23 using a snap-fit ​​structure. When the sliding body 24 moves, it generates friction with the upper surface of the crossbeam 23.

[0071] In this embodiment, each walking unit is configured with at least two sets of walking wheels, which can increase axial stability.

[0072] In this embodiment, the hydraulic unit includes:

[0073] A transverse hydraulic cylinder 25 has its base mounted on the first traveling unit 21, and the end of the actuating rod is connected to a sliding body 24.

[0074] The vertical hydraulic cylinder 26 is perpendicular to the upper surface of the base 1, and its base is mounted on the sliding body 24. The end of the actuating rod acts on the side template 29. In this embodiment, the position of the side template 29 is adjusted based on the horizontal hydraulic cylinder 25 and the vertical hydraulic cylinder 26. The hydraulic cylinders have large load capacity and are easy to control.

[0075] In this embodiment, in order to achieve reliable position adjustment, there are two sets of vertical cylinders 26, and the two sets of vertical cylinders 26 are arranged in parallel. In this embodiment, the axial consistency of the side template 29 is achieved based on the track. Therefore, this utility model only needs to configure two vertical cylinders 26 and one horizontal cylinder 25 to make the position and posture of the side template 29 meet the predetermined requirements.

[0076] In this embodiment, the transverse hydraulic cylinder 25 is rotatable. Due to the excessive weight of the template, the sliding body 24 may move under certain circumstances, resulting in a misalignment with the axis of the crossbeam 23. The rotatable design of the transverse hydraulic cylinder 25 of this utility model can effectively prevent damage to the side template unit 2 when this situation occurs.

[0077] In this embodiment, the ends of the two actuating rods of the two sets of vertical hydraulic cylinders 26 are respectively connected to the two flanges of the H-shaped steel frame 27;

[0078] H-beam 27 is fixedly connected to side formwork 29, with its flanges parallel to the axial direction of the T-beam. In this embodiment, side formwork 29 includes an outer wall that directly contacts the concrete and a steel frame 28 fixed to the outer wall. In this embodiment, H-beam 27 is fixed to the steel frame 28, or H-beam 27 itself is part of the steel frame 28.

[0079] In this embodiment, in order to improve the load resistance of the side template unit 2, the base of the transverse hydraulic cylinder 25 is rotatably mounted on the first traveling unit 21, and the rotating shaft is parallel to the first linear guide rail 5.

[0080] In this embodiment, in order to improve the operational stability of the side template unit 2, the first walking unit 21 is disposed in the first housing; the bottom of the first housing is provided with two limiting edges; the two limiting edges are respectively disposed on both sides of the first linear guide rail 5 to restrict the first walking unit 21 from derailing;

[0081] The second traveling unit 22 is disposed in the second housing; the bottom of the second housing is provided with two limiting edges, which are respectively disposed on both sides of the second linear guide rail 6 to prevent the second traveling unit 22 from derailing. In this embodiment, the limiting edges prevent the first traveling unit 21 and the second traveling unit 22 from derailing due to radial movement caused by the adjustment of the center of gravity of the side template 29.

[0082] In this embodiment, to accommodate the fabrication of various T-beams, the side formwork 29 can be replaced, such as... Figure 1 , 2 As shown, in this embodiment, a steel frame 28 is fixed to the outside of the side formwork 29. The function of the steel frame 28 is to provide load for the side formwork 29 during handling or pouring. In this embodiment, the steel frame 28 is fixed to the H-beam 27 with bolts, or the side formwork 29 is fixed to the steel frame 28 with bolts, so as to realize the replaceability of the side formwork 29.

[0083] In this implementation, in order to improve the stability of vertical posture adjustment, there are two sets of crossbeams 23 on each side template unit 2.

[0084] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
