Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a slurry leakage prevention device and an aluminum alloy formwork. Background Art

[0002] In building construction, aluminum alloy formwork is widely used due to its advantages such as light weight, high strength, and convenient assembly. The aluminum alloy formwork includes standard plates, inside corner C plates, and bottom R plates, which are used to build on concrete wall panels to pour and form concrete wall panels. In actual use, in order to facilitate the installation and removal of the formwork and eliminate the influence of the flatness deviation of the concrete floor, the aluminum alloy formwork is usually designed 10 mm lower than the theoretical height during formwork matching. Therefore, after the formwork is assembled, a gap of about 10 mm will be formed at the lower opening of the R plate. During the concrete pouring process, this gap is prone to cause slurry leakage, affecting the forming quality of the concrete and causing material waste.

[0003] To prevent slurry leakage, the commonly used method in current projects is mortar plugging, but this method has the following disadvantages: (1) Mortar plugging is time-consuming and laborious, affecting the construction progress; (2) A large amount of construction waste will be generated when removing the formwork after mortar plugging, which not only causes material waste but also increases the waste treatment cost. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a slurry leakage prevention device and an aluminum alloy formwork that are simple to operate, reduce the generation of construction waste, and can be reused.

The magnet is magnetically attached to the lower surface of the first pipe body. At least one deformable cavity is provided in the second pipe body, and the cavity is through at both ends in the length direction of the second pipe body. When the cavity deforms, the lower plate and the upper plate of the second pipe body forming the cavity approach each other, causing the second pipe body to extend laterally.

[0006] Preferably, two cavities are provided in the second pipe body, and the two cavities are separated by a vertical rib.

[0007] Preferably, the vertical rib is as long as the length of the second pipe body.

[0008] Preferably, the side wall of the second pipe body forming the cavity is a flat ellipse.

The R plate and the slurry leakage prevention device are connected to the lower end of the connecting plate through a connecting member. A lower opening is provided on one side of the two R plates close to each other, and the second tube body of the slurry leakage prevention device is blocked at the lower opening.

The horizontal plate is respectively attached to the connecting plate and the first tube body. The two vertical plates are arranged close to each other, and the lower surface of the vertical plate forms the lower opening.

[0015] Compared with the related art, the beneficial effects of the present utility model are as follows:

[0016] First, the slurry leakage prevention device uses the magnetic attraction of the magnet to install the deformable second tube body at the lower end of the first tube body. After the formwork is installed, the second tube body is vertically extruded by the limited space at the lower part of the R plate, so that the second tube body deforms and closely fits the concrete floor surface, effectively blocking the lower opening. The operation is simple, the structure is stable, there is no cumbersome adjustment action, it is material-saving and environmentally friendly, and can be reused;

[0017] Second, the slurry leakage prevention device forms a magnetic attraction conversion mechanism by setting the first tube body, solves the problem that the aluminum alloy formwork cannot be directly magnetically attracted, and can reduce the height of the second tube body, improve the blocking effect while reducing the material loss of the second tube body;

[0018] Third, the first tube body can use the bolt connection pair (i.e., the connecting member) supporting the aluminum alloy formwork, and bolts do not need to be separately provided, improving the material use efficiency and the universality of parts;

[0019] Fourth, after the slurry leakage prevention device is installed, the aluminum alloy formwork does not need to be adjusted again during the turnover process, nor does it need to use mortar for blocking, reducing the workload of workers, improving the construction efficiency, and saving resources and construction period.

[0030] As Figure 1 、 Figure 2 shown, a slurry leakage prevention device 1 provided in this embodiment includes a first pipe body 11, a second pipe body 12, a connecting piece 13, and a magnet 14.

[0031] As Figure 3As shown, the first pipe body 11 is a rectangular steel pipe with both ends being through. Multiple first holes 111 are formed on its upper surface, and multiple second holes 112 are formed on its lower surface. The multiple first holes 111 and the multiple second holes 112 correspond one by one to the holes on the connecting plate 3. The diameter of the second holes 112 is larger than that of the first holes 111. The connecting member 13 includes bolts and nuts, which can be shared with the bolts and nuts on the standard plate 2 of the aluminum alloy formwork. During installation, the bolts are inserted into the second holes 112, penetrate through the first holes 111, and then connect and install nuts. The second holes 112 provide an operating space for the bolts.

[0032] As Figure 4 shown, the second pipe body 12 is a flat oval rubber pipe, and strip-shaped magnets 14 are arranged on its upper surface. The interior of the second pipe body 11 is divided into two cavities 121 by vertical ribs 122. The cavities 121 make both ends of the second pipe body 12 through. The vertical ribs 122 are of the same length as the second pipe body 12. The magnets 14 are of the same length as the first pipe body 11. The height of the second pipe body 12 exceeds the lower opening 10 - 15 mm of the R plate 4 (as Figure 8 shown). The vertical ribs 122 can increase the lateral ductility of the second pipe body 12 under the action of vertical pressure and improve the sealing effect.

[0033] The second pipe body 12 and the magnets 14 are processed by external cooperation and are cut on site according to needs. After cutting, the magnets 14 are glued to the second pipe body 12.

[0034] As Figure 6 、 Figure 7 shown, the present utility model further provides an aluminum alloy formwork, which includes two R plates 4, two standard plates 2, and the anti - leakage slurry device 1 as described above. The two standard plates 2 are arranged at intervals, and a side formwork (not shown) is arranged between the two standard plates 2. The side formwork and the standard plates 2 enclose to form a column shape. A connecting plate 3 is provided at the lower end of the standard plate 2.

[0035] As Figure 6 、 Figure 8 shown, the R plate 4 includes a horizontal plate 41 and a vertical plate 42 that are vertically connected. The connecting member 13 is connected to the horizontal plate 41. The horizontal plate 41 is respectively in contact with the connecting plate 3 and the first pipe body 11. The vertical plates 42 connected to the two standard plates 2 are arranged close to each other, and the lower surface of the vertical plate 42 forms the lower opening 43. The second pipe body 12 of the anti - leakage slurry device 1 is blocked at the lower opening 43. The lower surface of the lower opening 43 abuts against the concrete floor slab 6, so that the second pipe body 12 is in a compressed state.

[0036] During use, first install the anti - leakage slurry device 1 and the R plate 4 to form the state as Figure 8 shown, and then install the aluminum alloy formwork at the location of the concrete wall panel 5 to be poured (as Figure 6As shown, after the aluminum alloy formwork is installed in place, the second pipe 12 is extruded by the concrete floor slab 6 and deformed laterally, thereby sealing the lower opening 43 and effectively preventing the concrete slurry from flowing out from the lower opening 43 during pouring.
