Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a three-wall automatic hydraulic opening and closing template with an adjustable structure. Background Technology

[0002] In modern construction industry, especially in the cast-in-place construction of large concrete structures (such as pipe galleries, canals, tunnels, shear walls, etc.), formwork engineering is a key link that determines construction quality, efficiency, and cost. For three-wall structures that need to be cast in one piece (such as U-shaped channels and box structures), traditional construction methods usually use decentralized, standardized flat formwork for assembly.

[0003] This type of planar formwork has drawbacks in use, such as being scattered, having low integration, and requiring numerous independent side and end formwork components for construction. Each formwork panel needs to be hoisted, transported, and positioned separately, making preparation work complicated and occupying a large amount of space and machinery.

[0004] Secondly, the installation process is cumbersome and inefficient. Traditional formwork is divided into several small sections according to the joints. The installation of the formwork relies entirely on lifting equipment such as tower cranes or truck cranes for multiple lifting operations, and requires a large number of workers on-site for bolting, support reinforcement, and other operations. Transferring requires the cooperation of forklifts and truck cranes, and the process is quite cumbersome due to the large number of sections. This process is not only time-consuming and labor-intensive, but also requires a high level of technical skill and teamwork from the workers, resulting in low overall installation efficiency. Furthermore, positioning accuracy and adjustment are difficult. After the dispersed formwork is assembled, it is difficult to ensure the flatness, verticality, and angles between them are precise. Adjusting the position and angle of the formwork often requires the use of tools such as crowbars and jacks, and repeated verification by manual experience, making precision control difficult and posing significant safety risks.

[0005] Now, a novel three-wall automatic hydraulic opening and closing formwork with an adjustable structure is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a three-wall automatic hydraulic opening and closing template with an adjustable structure to solve the problem of time-consuming and labor-intensive installation and positioning of existing three-wall templates mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a three-wall automatic hydraulic opening and closing template with an adjustable structure, including a hydraulic adjustment component, a mold component and three sets of gantry frames, wherein lifting rings are welded and fixed at the four corners of the top of the gantry frames.

[0008] The hydraulic adjustment assembly includes a sliding sleeve that is slidably connected to the front end of the top of the gantry frame. A first hydraulic cylinder is movably installed on the right side of the front end of the gantry frame. A second and a third hydraulic cylinder are fixedly installed at the bottom of the sliding sleeve. A fourth hydraulic cylinder is movably connected to the right side of the bottom of the sliding sleeve. Two sets of fifth hydraulic cylinders are movably installed on the right side inside the gantry frame. A hydraulic station is fixedly installed on the right side of the gantry frame.

[0009] As a further technical solution of this utility model, the shape and size of the inside of the sliding sleeve are adapted to the shape and size of the outside of the top front end of the gantry frame, and the sliding sleeve can slide left and right along the top of the gantry frame.

[0010] As a further technical solution of this utility model, the output end of the first hydraulic cylinder is movably connected to the top end of the sliding sleeve, and the first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder, the fourth hydraulic cylinder, the fifth hydraulic cylinder and the hydraulic station are connected by pipelines.

[0011] As a further technical solution of this utility model, the mold assembly includes a first side template, which is movably connected to the output end of the fourth hydraulic cylinder. A second side template and a third side template are provided below the sliding sleeve. A first end template is fixedly installed on the outer end face of the first side template and the second side template by bolts. A second end template is fixedly installed on the outer end of the second side template and the third side template by bolts. A side mold positioning frame is provided below the gantry frame. A fourth side template is hinged to the top of the side mold positioning frame. A third end template is fixedly connected between the outer end face of the third side template and the fourth side template by bolts.

[0012] As a further technical solution of this utility model, the first side template, the second side template, the third side template, and the side template positioning frame are divided into three sections: front, middle, and rear. The right side of the first side template is movably connected to the fifth hydraulic cylinder.

[0013] As a further technical solution of this utility model, the output end of the third hydraulic cylinder is fixedly connected to the top end of the second side template, and the output end of the second hydraulic cylinder and the top end of the third side template are fixedly connected.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the three-wall automatic hydraulic opening and closing template with adjustable structure not only realizes the function of hydraulic adjustment for easy positioning, but also realizes the function of disassembling and assembling the template; (1) By setting up a hydraulic adjustment component, when using it, the three wall steel bars are pre-tied to the corresponding positions at the construction site, and template accessories such as water passage, joint plate, and guardrail installation groove are pre-installed. The hoisting equipment lifts the gantry frame through the lifting ring. The mold is divided into three sections. The middle end is pre-installed, and then the first and last ends are installed. As the gantry frame is lowered into place, the first hydraulic cylinder pushes the sliding sleeve to slide left and right, which can drive the first side template, the second side template, and the third side template below to move left and right to adjust their positions. The second hydraulic cylinder, the third hydraulic cylinder, and the fourth hydraulic cylinder extend downwards, which can lower the side template, realizing the function of hydraulic adjustment for easy positioning. (2) By setting up lifting rings and mold components, when in use, as the first side template, the second side template, and the third side template are lowered into place, the first end template, the second end template, and the third end template are installed and fixed by bolts. After the pouring is completed, the first end template, the second end template, and the third end template are removed. The second hydraulic cylinder, the third hydraulic cylinder, and the fourth hydraulic cylinder retract synchronously to raise the first side template, the second side template, and the third side template. Then the hoisting equipment raises the gantry frame, which can quickly demold and realize the function of disassembling and assembling molds. Attached Figure Description
