Technical Field

[0001] The present application relates to the technical field of construction engineering, and in particular to a formwork removal device for small spaces of a climbing formwork system. Background Art

[0002] Climbing formwork technology has been widely used in the construction of super-high-rise vertical structures. It is easy to operate, simple in structure, good in stability, safe in high-altitude operations, and has a fast climbing speed. Due to its flexible assembly and strong structural adaptability, it can climb vertically or along the slope. According to the characteristics of the building structure, the corresponding machine position is designed and a reasonable formwork structure is configured to provide a better working environment for the construction of super-high-rise vertical structures.

[0003] The climbing formwork system has high requirements on the formwork system used for core tube construction. The overall formwork system of the climbing formwork system adopts the form of "external climbing and internal support" to achieve simultaneous construction of the horizontal and vertical structures of the core tube. When there is a narrow structural space in the core tube, the installation and removal of the formwork is more difficult. Utility Model Content

[0010] Optionally, an operating hole is further provided on the extension portion, and a diameter of the operating hole is larger than that of the fixing hole.

[0011] By adopting the above technical solution, the staff can insert the operating rod into the operating hole, and then twist the driving rod through the operating rod, thereby improving the convenience of the staff during operation.

[0012] Optionally, the extension portion is provided with an external thread, the connecting tube is provided with an internal thread, and the connecting tube is threadedly connected to the extension portion.

[0017] By adopting the above technical solution, the bolts simultaneously connect the support block and the template, which facilitates the connection or separation of the support block and the template.

[0018] Optionally, the support block is T-shaped.

[0019] Optionally, the driving block is provided with a convex column 1 on both sides opposite to each other, and the supporting block is provided with a convex column 2 on both sides opposite to each other. The supporting arm includes two parallel supporting plates, one end of the supporting plate is rotatably connected to the convex column 1, and the other end of the supporting plate is rotatably connected to the convex column 2.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1 -Attached Figure 4 This application is described in further detail.

[0031] The embodiment of the present application discloses a formwork removal device for a small space of a climbing formwork system.

[0032] Example 1

[0033] Reference Figure 1 and Figure 2 A demolding device for a small space of a climbing formwork system includes a driving block 1, a supporting block 2, a supporting arm 3, a driving rod 4, a connecting tube 5 and a limiting pin 6. Two driving blocks 1 are provided, and two bosses 10 are fixedly connected to the opposite sides of the driving block 1, and a threaded hole 11 is also provided on the driving block 1. Two supporting blocks 2 are provided, and the supporting block 2 in the present application is a T-shaped block, and two bosses 20 are fixedly connected to the opposite sides of the supporting block 2, and a mounting hole 21 is also provided on the supporting block 2, and the mounting hole 21 is used for the bolt to pass through.

[0034] Reference Figure 1 and Figure 2 A support arm 3 is provided between the driving block 1 and the supporting block 2. The support arm 3 includes two parallel supporting plates 30. The two ends of the supporting plate 30 are respectively rotatably connected with two adjacent bosses 10 and 20. The two driving blocks 1, the two supporting blocks 2 and the four supporting arms 3 form a whole. The driving rod 4 includes a connecting portion 40 located in the middle. The connecting portion 40 has a smooth surface. A threaded portion 1 41 and a threaded portion 2 42 are respectively provided at the two ends of the connecting portion 40. The threaded rotation directions of the threaded portion 1 41 and the threaded portion 2 42 are opposite. The driving rod 4 is penetrated in the threaded hole 11. One of the driving blocks 1 is threadedly connected with the threaded portion 1 41, and the other driving block 1 is threadedly connected with the threaded portion 2 42.

[0035] Reference Figure 1 and Figure 2 An extension portion 43 is provided at one end of the threaded portion 41 away from the connecting portion 40, and an extension portion 43 is also provided at one end of the threaded portion 42 away from the connecting portion 40. The extension portion 43 in this embodiment is smooth, and two fixing holes 430 and an operating hole 431 are provided on the extension portion 43. An operating rod for a staff member to rotate the driving rod 4 can be inserted into the operating hole 431, and the aperture of the operating hole 431 is larger than that of the fixing hole 430.

[0036] Reference Figure 1 and Figure 2 The connecting tube 5 is used to connect the two driving rods 4. The connecting tube 5 is detachably sleeved on the two adjacent extensions 43. Four clearance holes are opened on the connecting tube 5, and the clearance holes correspond to the fixing holes 430 one by one. The limiting pin 6 is detachably inserted between the clearance holes and the fixing holes 430, so as to fix the connecting tube 5 and the driving rod 4.

[0037] The implementation principle of Example 1 is as follows: the driving rod 4 is used to drive the two driving blocks 1 to move closer to or away from each other, and the supporting block 2 is used to be connected and fixed with the template bolts. By twisting the driving rod 4, the two driving blocks 1 are moved closer to each other, and the two supporting blocks 2 are moved away from each other laterally and support the template. When the template needs to be removed, the bolts on the supporting blocks 2 are removed, and the driving rod 4 is twisted to move the two supporting blocks 2 closer to each other, so that the demolding device can be easily taken out to complete the template removal work.

[0038] Example 2

[0039] Reference Figure 3 The difference between this embodiment and embodiment 1 is that the extension portion 43 in this embodiment is provided with an external thread, the connecting tube 5 is provided with an internal thread, and the extension portion 43 is threadedly connected to the connecting tube 5.

[0040] The implementation principle of Example 2 is as follows: the extension portion 43 is threadedly matched with the connecting tube 5, thereby strengthening the connection strength between the driving rod 4 and the connecting tube 5 in the length direction, making the matching of the two driving rods 4 more stable.

[0041] Example 3

[0042] Reference Figure 4 The difference between this embodiment and embodiment 1 is that the extension portion 43 in this embodiment is in the shape of a rectangular plate, and a rectangular slot is provided in the corresponding connecting tube 5.

[0043] The implementation principle of Example 3 is as follows: after the extension portion 43 is inserted into the connecting tube 5, due to the shape restriction of the extension portion 43, the driving rod 4 and the connecting tube 5 have a higher matching strength when rotating, thereby preventing rotational dislocation.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
