Description

Technical Field

[0001] This utility model relates to the field of post-cast strip support structure for basement roof slabs, and more specifically, to a post-cast strip support structure for basement roof slabs. Background Technology

[0002] During the construction of the basement, a post-pouring strip is reserved. The post-pouring strip is a temporary construction joint left at the corresponding position of the foundation beam in accordance with the design or construction specifications to prevent harmful cracks that may be caused by uneven shrinkage or settlement of the cast-in-place reinforced concrete structure. When supporting the top formwork at the post-pouring strip, a support structure is required. However, the existing post-pouring strip support structure still has some defects in use.

[0003] For example, the independent support structure for the post-cast strip of the roof slab proposed in application number CN201821382189.5 relates to the field of engineering facilities. It includes a main keel, secondary keel, panel, and support frame. The support frame is equipped with a top support, which includes a support plate, a strut fixed to the support plate, and an adjusting compression nut threadedly connected to the strut. A clamping assembly is provided on the support plate, including a spring. One end of the spring is fixed to the side of the support plate away from the strut, and the other end is fixedly connected to a pressure plate. Clamping elements are symmetrically arranged on the support plate and on both sides of the spring. The structure consists of mutually perpendicular L-shaped horizontal and vertical plates. The clamping components are hinged to the support plate. The horizontal plates of the two clamping components are located between the support plate and the pressure plate, and the vertical plates extend from the side of the pressure plate. In actual use, the bottom of the independent support structure for the post-pouring strip in this application is directly connected to the pad and the ground during the support process, which reduces its stability. Furthermore, it is not convenient to fold and store the independent support structure for the post-pouring strip in this application to reduce its storage volume. At the same time, there is also instability when clamping and fixing the keel.

[0004] In the prior art, such as the authorized announcement number CN221957189U, this utility model discloses a support structure for the post-cast strip of a basement roof slab, including a sleeve, a mounting base, a lifting rod, and a keel. This support structure for the post-cast strip of a basement roof slab is provided with a sleeve, a connecting seat, an auxiliary support mechanism, a mounting base, a lifting rod, a positioning groove, and positioning bolts. This allows the auxiliary support mechanism to expand and contract, facilitating the formation of a triangular structure with the ground when expanded, which improves the stability of the keel support. When contracted, the lifting rod contracts within the sleeve, enhancing the ease of storage of the support structure. The engagement of the positioning bolts with the positioning grooves at different positions allows for positioning of the extension length of the lifting rod, facilitating stable support for keels of different heights and improving usability. The threaded clamping mechanism allows for adjustment of the internal clamping distance, thus adapting to keels of different specifications and sizes.

[0005] In the aforementioned patent, a lifting adjustment mechanism is used, but it adopts a lifting rod structure and uses positioning bolts for positioning. It cannot be directly adjusted upwards, the adjustment stroke is fixed, and it cannot be precisely adjusted when the height is different. In addition, the upper clamping mechanism adopts a threaded screw structure, which is relatively complex and costly. Utility Model Content

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a support structure for the post-cast strip of the basement roof slab. The structure uses a compression nut to rotate and drive the telescopic support jacking pipe to rise and tighten. Its adjustment stroke can be flexibly adjusted and the adjustment is precise. The clamping mechanism uses bolt compression to drive the compression positioning block to retract and clamp. The structure is simple and low in cost.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A support structure for the post-cast strip of a basement roof slab includes a threaded support rod. A telescopic support pipe is slidably sleeved on the outer surface of the threaded support rod. A compression nut is threadedly connected to the lower outer surface of the threaded support rod. The compression nut presses upward against the lower surface of the telescopic support pipe. An arched plate is fixed to the upper surface of the telescopic support pipe. A compression positioning block is sleeved on the outer surface of the arched plate. Bolts are provided on the side of the arched plate. The telescopic support pipe is raised and tightened by rotating the compression nut. The adjustment stroke is flexible and precise. The clamping mechanism clamps the pipe by compressing the bolts to retract the compression positioning block. The mechanism is simple and low in cost.

[0009] Furthermore, a support block is fixed to the lower surface of the threaded support rod, and a flip-type support leg is hinged to the inner surface of the support block.

[0010] Furthermore, the support block adopts a square block structure, with grooves on all four sides of the support block, and its flip-type support legs are hinged to the inner surface of the grooves around the support block.

[0011] Furthermore, threaded holes are provided on the left and right sides of the arched seat, and the outer surface of the bolt is connected to the inner surface of the threaded hole of the arched seat.

[0012] Furthermore, the flip-type support legs are distributed on the four surfaces of the support block, and the inner end surface of the flip-type support legs is provided with a convex shaft, which is hinged to the inner surface of the support block.

[0013] Furthermore, the inner end surface of the flip-up support leg is configured with a rounded chamfer structure.

[0014] Furthermore, the outer surface of the extrusion positioning block is provided with a sleeve interface, and the inner surface of the sleeve interface of the extrusion positioning block is sleeved on the outer surface of the arched plate.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) By using the rotation of the compression nut to drive the telescopic support jacking pipe to rise and tighten, its adjustment stroke can be flexibly adjusted and its adjustment is precise. The clamping mechanism uses bolt compression to drive the compression positioning block to contract for clamping. Its mechanism is simple and low cost. Attached Figure Description
