Description

Technical Field

[0001] This utility model relates to an easy-to-disassemble ribbed floor slab formwork, belonging to the field of ribbed floor slab formwork construction technology. Background Technology

[0002] The traditional method for removing the formwork of a ribbed slab floor system involves two or more people using pry bars to loosen the formwork around its perimeter, and then manually pulling it off. The main tools used for removing the formwork are various types of pry bars and hook rods.

[0003] The above method has the following drawbacks:

[0004] ① It requires two or more people to operate under the mold shell at the same time, and there is a high risk of injury from the mold shell falling.

[0005] ②The pry bar is a single-point pry bar, which causes greater damage to the surrounding area of ​​the mold shell.

[0006] ③ The crowbar can damage the concrete around the formwork, affecting the overall appearance quality.

[0007] ④ The length of the crowbar is limited, and the space for exerting force is also limited. A special operating platform needs to be set up for demolding. Utility Model Content

[0008] The technical problem to be solved by this utility model is to provide an easily disassembled ribbed floor slab formwork to solve the technical problems existing in the prior art.

[0009] The technical solution adopted by this utility model is as follows: an easy-to-disassemble ribbed floor slab formwork, including a formwork body, a tie rod connected between two opposite inner sidewalls of the formwork body, a vertically downward-arranged fixing cylinder fixed to the inner top of the formwork body, a notch provided on the lower end of the sidewall of the fixing cylinder to allow the tie rod to pass through, and an internal thread provided on the lower end of the inner sidewall of the fixing cylinder; it also includes a movable rod, the upper end of which is provided with an external thread that mates with the internal thread.

[0010] Preferably, a fixing lug is fixed on the inner sidewall of the mold shell body, and the tie rod is hinged to the fixing lug.

[0011] Preferably, the movable rod is a telescopic rod.

[0012] Preferably, a rectangular frame-shaped handle is fixed to the lower end of the moving rod.

[0013] Preferably, the outer periphery of the fixing cylinder is provided with an annular groove for gripping.

[0014] The beneficial effects of this utility model are:

[0015] 1. Compared with the prior art, this utility model can reduce the damage rate of the mold shell and reduce the damage to the finished concrete product during demolding; it can improve construction efficiency and save labor costs; it can improve the safety and quality assurance rate of demolding operations; the integrity of the mold shell is strengthened, and the guarantee rate of casting and molding is improved.

[0016] 2. This utility model has a simple structure and can be mass-produced in a factory. One operator can operate it while standing on the ground, avoiding the drawback of needing to use mobile scaffolding when using a pry bar to dismantle the mold. At the same time, the threaded connection between the loose mold shell and the moving rod effectively prevents the mold shell from falling off at will, reducing safety risks and preventing excessive damage to the mold shell material itself. Attached Figure Description

[0017] Figure 1 This is a schematic diagram of the overall structure of this utility model.

[0018] The reference numerals in the accompanying drawings of the instruction manual include: mold body 1, fixing cylinder 2, fixing lug 3, tie rod 4, notch 5, and moving rod 6. Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1:

[0021] A type of easily disassembled ribbed floor slab formwork, such as Figure 1 As shown, the device includes a mold shell body 1. A tie rod 4 is connected between the front and rear inner sidewalls and between the left and right inner sidewalls of the mold shell body 1. A fixing lug 3 is fixed on each of the four inner sidewalls of the mold shell body 1. The tie rod 4 is hinged to the fixing lug 3. A vertically downward-facing fixing cylinder 2 is fixed at the center of the inner top of the mold shell body 1. A notch 5 is provided in the four directions (front, rear, left, right) of the lower end of the sidewall of the fixing cylinder 2 to allow the tie rod 4 to pass through. The lower end of the inner sidewall of the fixing cylinder 2 is also provided with an internal thread. In this embodiment, a moving rod 6 is also included. The upper end of the moving rod 6 is provided with an external thread that mates with the internal thread.

[0022] In use, the worker stands on the ground, lifts the movable rod 6, and rotates it to engage with the fixed cylinder 2. As the movable rod 6 is continuously rotated into the fixed cylinder 2, it pushes the tie rod 4 upward, generating a gradually increasing upward pulling force from four directions, causing the formwork body 1 to simultaneously detach from the concrete contact surface. Then, the worker pulls the movable rod 6 downward forcefully, causing the top of the formwork body 1 to detach from the top concrete, thus removing the entire formwork body 1. The movable rod 6 is then separated from the formwork body 1. Similarly, the removal of the next formwork is performed, repeating this process until all formworks are removed.

[0023] To facilitate the removal of mold shells of different heights and to accommodate workers of different heights, the movable rod 6 in this embodiment is a telescopic rod, whose length can be adjusted according to actual needs and space constraints.

[0024] In this embodiment, a rectangular handle is fixed to the lower end of the moving rod 6. The handle facilitates both rotating the moving rod 6 and pulling it downwards.

[0025] In this embodiment, the outer periphery of the fixed cylinder 2 is provided with an annular groove for gripping. During the process of separating the moving rod 6 from the mold shell, one hand holds the annular groove and the other hand holds the moving rod 6, which facilitates the separation of the moving rod 6 from the mold shell.

[0026] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
