Description

Technical Field

[0001] The invention relates to the technical field of jacking, in particular to an adjustable jacking and quick-detachable building template supporting structure. Background Art

[0002] The jacking supports effectively transfer and disperse the construction load by supporting the formwork, ensuring the stability of the formwork and preventing deformation or displacement. The existing jacking supports are all adjustable up and down, mainly used to meet different construction needs and ensure that the structure height meets the design requirements. The use of jacking supports can reduce the workload of setting up the support system and improve construction efficiency. The jacking supports have sufficient load-bearing capacity and stability, which can reduce the risk of formwork collapse and ensure the safety of construction workers.

[0003] In addition, the top support is generally composed of three parts: a chassis, a lead screw, and an adjusting nut. It is often used in conjunction with steel pipes and scaffolding to support the building formwork. It is mainly used to support the floor formwork between the building support columns and the load-bearing beams.

[0004] Existing jack supports usually use a lead screw and an adjusting nut to adjust the height of the jack support. During installation, the lead screw needs to be inserted into the steel pipe of the scaffolding. Therefore, in order to ensure that the lead screw and the jack support above will not shift, it is usually necessary to insert the lead screw into the steel pipe to a certain depth to increase the contact area between the lead screw and the inner surface of the steel pipe to ensure that the lead screw will not cause the jack support above to tilt and shift. However, this method has certain safety hazards when removing the formwork after the template solidifies, because the lead screw has a long length inserted into the interior of the steel pipe. If the jack support needs to be completely removed, the steel pipe below and the scaffolding associated with it need to be disassembled together. If the template above falls off, it will directly fall on the construction workers who are doing the dismantling work below. Summary of the invention

[0013] Preferably, the outer surface of the threaded rod is provided with four vacancies in an equidistant circular array, and the inner surface of the extension tube is provided with four filling blocks in an equidistant circular array, and the filling blocks can fill the vacant spaces and are slidably connected to the outer surface of the threaded rod.

[0014] The application provides a quick-disassembly building formwork support structure using the following technical solutions:

[0015] The quick-detachable building template support structure comprises an assembly ring 1, the inner wall of which is fixedly mounted on the outer surface of a main vertical pole, the outer surface of which is provided with two flanges, the outer surfaces of which are in close contact with the bottom end of the assembly ring 1.

[0016] Preferably, an assembling ring 2 is fixedly mounted on the outer surface of the assembling ring 1, a tightening belt is sleeved on the outer surface of the assembling ring 2, and the tightening belts are tightly attached to each other by screws.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present application cooperates between the main vertical pole, the fixed plate, the inlay plate, the threaded rod, the inlay frame and the combined threaded sleeve. The main vertical pole serves as the main load-bearing rod body to provide support and load-bearing for the upper components. The inlay plate can be directly connected to the fixed plate, and the inlay frame can be connected to the inlay plate. The threaded rod can be inserted into the inlay frame, the inlay plate and the main vertical pole together with the top support plate. They can be connected together through gravity and pressure from above. When adjusting the height, the adhesion between the combined threaded sleeve and the threaded rod can be loosened, so that the threaded rod inlay frame can easily drive the combined threaded sleeve to rotate, and the threaded rod drives the top support plate above to adjust the height up and down. When disassembly is required, only the adhesion between the combined threaded sleeve and the threaded rod needs to be loosened, so that the loosened combined threaded sleeve can be easily connected to the fixed plate. The adhesion force between the sleeve and the threaded rod can be reduced, and the combined threaded sleeve can be rotated and moved upward on the threaded rod more easily, so that the threaded rod can slide downward with the top support plate above, and then the top support plate can be directly removed from above the threaded rod. After the top support plate is removed, the overall top support will be reduced by a certain height, and the threaded rod and the combined threaded sleeve can be moved upward and pulled out from the main pole, and the inlay frame and the inlay plate can be pulled out and removed from the main pole one by one. There is no need to dismantle the supporting structure including the main pole throughout the process. When the upper template falls off, the lower supporting structure including the main pole can receive the fallen template from above, providing safety shelter for the construction workers performing the demolition operation, thereby solving the problem that the upper template will directly fall off and hit the workers below.

[0019] 2. In the present application, a fixed seat, a slot, an auxiliary seat, a mosaic plate, a mosaic board and a fixed plate are matched together. When the mosaic plate is placed on the fixed plate, the mosaic board on the bottom of the mosaic plate can be inserted into the slot and attached to the auxiliary seat, so that the mosaic plate will not rotate on the fixed plate, thereby preventing the top support plate above from rotating, causing the top support plate and the horizontal groove on the bottom of the template to be misaligned.

[0020] 3. In the present application, the threaded rod, the extension tube, the gap and the filling block are matched. When the threaded rod is inserted into the extension tube, the gap is provided on the surface of the threaded rod, so that the threaded rod is not a complete circle whether viewed from above or above. However, the filling block of the extension tube can fit together with the threaded rod, so that the threaded rod will not rotate when inserted into the extension tube.
