Description

Technical Field

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

[0002] In construction projects, wooden formwork is widely used because it is easy to process and can be arbitrarily processed according to the specific geometric shape of the component. Compared with metal formwork, it has a small one-time investment and is easy to purchase. By using wooden formwork, the accuracy of the position of each part of the concrete component can be guaranteed, and the size and shape of the concrete structure can be guaranteed to meet the design requirements. At present, when removing the wall formwork in concrete, the staff mostly use sharp tools such as crowbars to remove it. By inserting the crowbar into the gap between the wooden formwork and the wall, and then prying the formwork, it can be made to fall off. Although this method can achieve the removal of the wooden formwork, due to the small contact area between the crowbar and the main structural component and the wooden formwork, it is very easy to cause varying degrees of damage to the main structural component and the formwork itself during the operation of the crowbar, which may require the main structural component to be repaired later, and it will also affect the recycling of the wooden formwork. Therefore, a wooden formwork removal tool is proposed to address the above problems. Utility Model Content

[0003] The technical problem to be solved by the utility model overcomes the existing defects and can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A wooden formwork removal tool comprises a fixing sleeve and a formwork, wherein the right end of the fixing sleeve is fixedly connected to a fixing rod, the inner side of the fixing sleeve is rotatably connected to a bidirectional threaded shaft with opposite thread directions on both sides, the outer side of the bidirectional threaded shaft is spirally connected to a bracket, and the bracket is slidably connected to the fixing sleeve, one end of the bracket is fixedly connected to a pry shaft with a slot on the outer side, the formwork is in contact with the pry shaft, one end of the outer side of the pry shaft is provided with an arc-shaped support rod, and the other end of the outer side of the pry shaft is in contact with a limit frame in contact with the formwork.

[0006] As a further improvement of the present invention, a worm gear is fixedly connected to the center of the outer side of the bidirectional threaded shaft, and a worm screw penetrating the fixed sleeve and the fixed rod is meshedly connected to the outer side of the worm gear, and the worm screw is rotationally connected to the fixed sleeve and the fixed rod.

[0007] As a further improvement of the present invention, a bolt passing through the template is spirally connected to the left side of the template, and the bolt is spirally connected to the limiting frame.

[0008] As a further improvement of the present invention, a rotating sleeve is fixedly connected to the top end of the support rod, and the rotating sleeve is rotatably connected to the pry shaft.

[0022] Example 2

[0023] like Figure 2 As shown, in order to solve the problem of inconvenience in controlling the pry shaft 6 to be inserted between the template 13 and the limit frame 14, a worm gear 8 is fixedly connected to the outer center of the bidirectional threaded shaft 4, and a worm 9 that passes through the fixed sleeve 1 and the fixed rod 2 is engaged with the outer side of the worm gear 8, and the worm 9 is rotatably connected to the fixed sleeve 1 and the fixed rod 2. By rotating the worm 9 to engage the worm gear 8, the bidirectional threaded shaft 4 and the bracket 5 are further controlled to be spirally connected, which facilitates the control of the pry shaft 6 to be inserted between the template 13 and the limit frame 14 through the bracket 5.

[0024] Example 3

[0025] like Figure 4 As shown, in order to solve the problem of inconvenience in installing the limit frame 14, the left side of the template 13 is spirally connected with a bolt 15 that penetrates the template 13, and the bolt 15 is spirally connected to the limit frame 14. By inserting the limit frame 14 into the right end of the template 13 and then rotating the bolt 15 to spirally connect it with the template 13 and the limit frame 14, the installation of the limit frame 14 is facilitated.

[0026] Example 4
