[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0032] Example 1

[0033] like Figure 1 As shown, a tool for protecting the integrity of a multi-rib beam and facilitating the removal of a formwork shell comprises:

[0034] A bracket, a first protective plug plate 1 and a second protective plug plate 2 are fixedly and obliquely distributed on the bracket, the first protective plug plate 1 and the second protective plug plate 2 form an eight-shaped structure, the bundle end of the eight-shaped structure is located at the lower end, the first protective plug plate 1 and the second protective plug plate 2 are used to be respectively inserted into the gaps between the two inclined sides of the dense-ribbed beam 7 and the mold shell 8. Specifically, it can be understood that: the two inclined sides of the dense-ribbed beam 7 each have a mold shell 8, the first protective plug plate 1 is used to be inserted into the gap between one inclined side of the dense-ribbed beam 7 and the mold shell 8, and the second protective plug plate 2 is used to be inserted into the gap between the other inclined side of the dense-ribbed beam 7 and the mold shell 8.

[0035] A method for protecting the integrity of a multi-ribbed beam and facilitating the removal of a formwork, using the tool for protecting the integrity of a multi-ribbed beam and facilitating the removal of a formwork, comprising the following steps:

[0036] S1, insert the first protective plug plate 1 and the second protective plug plate 2 into the gaps between the two inclined sides of the multi-rib beam 7 and the formwork 8 respectively;

[0037] S2, install the bracket above the inner frame steel pipe 9;

[0038] S3, insert the crowbar 9 from the gap between the mold shell 8 and the outer side of the first protective plug plate 1 or the second protective plug plate 2, and let the force point of the crowbar 9 during use act on the first protective plug plate 1 or the second protective plug plate 2 to remove the mold shell 8.

[0039] Example 2

[0040] like Figure 1 As shown, this embodiment is a further improvement on the basis of embodiment 1, and the details are as follows:

[0041] The bracket includes: a telescopic mechanism 3 and a bracket 4, the telescopic mechanism 3 is distributed in the horizontal direction, the telescopic mechanism 3 is fixed to the upper end of the bracket 4, the telescopic mechanism 3 is respectively fixed to the lower ends of the first protective plug plate 1 and the second protective plug plate 2, and the telescopic mechanism 3 is used to adjust the horizontal spacing between the first protective plug plate 1 and the second protective plug plate 2. For dense-ribbed beams 7 of different sizes, the distance between the two inclined sides will be different, so by adjusting the horizontal spacing between the first protective plug plate 1 and the second protective plug plate 2 through the telescopic mechanism 3, the tool can be adapted to the dense-ribbed beams 7 with different spacings between the two inclined sides, and the tool has better versatility.

[0042] Example 3

[0044] The telescopic mechanism 3 includes: a slide rail 310 and a sliding plate 320 slidably connected to the slide rail 310. The sliding plate 320 can be designed to be T-shaped or dovetail-shaped, and can be processed specifically according to actual needs. A tension bolt 330 is fixed on the slide rail 310. The tension bolt 330 is used to lock the sliding plate 320 (the sliding plate 320) on the slide rail 310 when the sliding plate 320 slides to any position. The lower end of the first protective plug plate 1 is fixedly connected to the slide rail 310, and the lower end of the second protective plug plate 2 is fixedly connected to the sliding plate 320. An L-shaped structure is formed between the first protective plug plate 1 and the slide rail 310, and an L-shaped structure is formed between the second protective plug plate 2 and the sliding plate 320. It is very convenient to adjust the spacing between the first protective plug plate 1 and the second protective plug plate 2, and the stability is good. In order to ensure that the sliding plate 320 and the slide rail 310 are sufficiently smooth, lubricating oil can be appropriately added for lubrication.

[0047] The lower end of the first protective plug plate 1 is connected to the slide rail 310 via the first angle adjustment mechanism 5, and the lower end of the second protective plug plate 2 is connected to the sliding plate 320 via the second angle adjustment mechanism 6. For different sizes of multi-ribbed beams 7, the inclination angles of the inclined surfaces thereof may be different, so the inclination angles of the first protective plug plate 1 and the second protective plug plate 2 can be adjusted respectively by the first angle adjustment mechanism 5 and the second angle adjustment mechanism 6 to adapt to the inclination angles of the inclined surfaces of the multi-ribbed beams 7, ensuring that the first protective plug plate 1 can be inserted into the gap between one inclined surface side of the multi-ribbed beam 7 and the formwork 8, and the second protective plug plate 2 can be inserted into the gap between the other inclined surface side of the multi-ribbed beam 7 and the formwork 8.

The first adjusting bolt passes through the second through hole and the first through hole to lock the first protective plug plate 1 and the slide rail 310. When adjusting the inclination angle of the first protective plug plate 1, loosen the nut of the first adjusting bolt, manually adjust the inclination angle of the first protective plug plate 1 to the expected angle, and then tighten the nut of the first adjusting bolt, which can facilitate disassembly and installation as well as angle adjustment.

[0051] Furthermore, the second angle adjustment mechanism 6 includes: a second adjusting bolt, a third through hole is opened at the end of the sliding plate 320, the third through hole is horizontally distributed, and the axis of the third through hole is perpendicular to the sliding direction of the sliding plate 320, and a fourth through hole is opened at the lower end of the second protective plug plate 2 and parallel to the third through hole. The second adjusting bolt passes through the fourth through hole and the third through hole to lock the second protective plug plate 2 and the sliding plate 320. When adjusting the inclination angle of the second protective plug plate 2, loosen the nut of the second adjusting bolt, manually adjust the inclination angle of the second protective plug plate 2 to the expected angle, and then tighten the nut of the second adjusting bolt, which can facilitate disassembly and installation as well as angle adjustment.

[0052] The first angle adjustment mechanism 5 and the second angle adjustment mechanism 6 do not affect the smoothness of the cooperation between the sliding plate 320 and the sliding rail 310 .

The size of the support 420 is larger than the inner diameter of the inner frame steel pipe. By rotating the support 420 on the screw rod 410, the position of the support 420 on the screw rod 410 can be adjusted, thereby adjusting the length of the screw rod 410 entering the inner frame steel pipe to adjust the height of the first protective plug plate 1 and the second protective plug plate 2.
