Description

Technical Field

[0001] The utility model relates to the technical field of building tools, in particular to a wood formwork removal tool. Background Art

[0002] In construction projects, wooden formworks serve as supports, mold bottoms and protective layers during concrete construction. They bear the weight and pressure of concrete pouring, ensure that the concrete has sufficient time to harden and solidify, and make the concrete surface smooth and flat. Wooden formworks are widely used in construction projects because they are easy to process and can be processed arbitrarily according to the specific geometric shapes of components. Compared with metal formworks, they have a small one-time investment and are easy to purchase. In the process of using wooden formworks, when the wooden formworks are removed after the concrete is formed, sharp tools such as crowbars are often used to pry the gaps between the formworks to make the formworks fall off. Although this method can realize the removal of the wooden formworks, it is very easy to cause varying degrees of damage to the main structural components and the formworks themselves during the operation. Therefore, a wooden formwork removal tool is proposed to address the above problems. Utility Model Content

[0020] Example 2

[0021] like Figure 2 As shown, in order to solve the problem that the movable shovel board 4 cannot be automatically reset after the wooden formwork reset handle 11 is removed, a first spring 7 is provided at the top end of the outer side of the pull rope 6, and the first spring 7 is fixedly connected to the slider 5 and the fixed seat 2. After the wooden formwork reset handle 11 is removed, the elastic force of the first spring 7 after being compressed is restored to further push the slider 5 at the bottom end of the movable shovel board 4, thereby facilitating the automatic reset of the movable shovel board 4.

[0022] Example 3

[0023] like Figure 2 As shown, in order to solve the problem that when the control reel 9 reels the pull rope 6, large friction will be generated between the pull rope 6 and the fixed seat 2, the inner left end of the fixed seat 2 is rotatably connected to the guide shaft 8 through a rotating shaft, and the guide shaft 8 is in contact with the pull rope 6. When the control reel 9 reels the pull rope 6, the pull rope 6 is guided by the guide shaft 8, thereby avoiding large friction between the pull rope 6 and the fixed seat 2.

[0024] Example 4

[0025] like Figure 1-2 As shown, in order to solve the problem that the handle 11 cannot be stably folded after the device is used, the outer bottom end of the handle 11 is slidably connected with an elastic rope 12 that penetrates the handle 11, and the elastic rope 12 is arranged in a ring shape. The elastic rope 12 is in contact with the operating rod 1. After the device is used, the elastic rope 12 arranged in a ring shape at the outer bottom end of the handle 11 is put on the outer bottom end of the operating rod 1, which facilitates the stable folding of the handle 11.

[0026] Example 5
