Description

Technical Field

[0001] This utility model relates to the field of building formwork technology, specifically a movable structure for stair formwork. Background Technology

[0002] In modern construction engineering, stairs are a core component connecting different floors, and their construction quality and aesthetics directly affect the overall quality of the building. Stair formwork, as a key tool in stair construction, is of paramount importance.

[0003] Aluminum alloy formwork is widely used in formwork support for building construction projects due to its excellent forming effect and lightweight characteristics.

[0004] Traditional aluminum alloy stair formwork has a fixed size and cannot be adjusted to accommodate different stair sizes in various buildings. It requires pre-cutting of staircases of different sizes for each building, resulting in a large initial investment and a long processing cycle. In addition, the surface of the aluminum formwork at the bottom of the staircase is smooth, and the steel reinforcement protective layer spacers need to be tied to the steel reinforcement one by one, which causes inconvenience to the workers.

[0005] Furthermore, the existing enclosed staircase formwork structure makes it inconvenient to clean up construction debris after the steel reinforcement is laid, requiring the use of specialized machinery for cleaning, which results in low cleaning efficiency. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a movable stair formwork structure, which solves the problems of fixed dimensions, poor adjustability, high initial investment, difficulty in fixing concrete pads on the bottom of the staircase, and difficulty in cleaning up construction waste in traditional stair formwork.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a movable stair formwork structure, comprising a base plate, a side plate fixedly connected to one side of the base plate by bolts, a groove machined on the upper part of the side plate, multiple connecting plates pressed against the outer wall of the side plate, a fifth threaded rod threadedly connected to the inner wall of the multiple connecting plates, a second nut threadedly connected to the outer wall of the fifth threaded rod, the outer wall of the second nut pressed against the outer wall of the side plate, multiple horizontal plates fixedly connected to the bottom of the multiple connecting plates, multiple vertical plates attached to the outer wall of each of the multiple horizontal plates, the outer walls of the multiple horizontal plates and the multiple vertical plates being attached to the outer wall of the side plate, a first threaded rod threadedly connected to the inner wall of each of the multiple vertical plates, the outer walls of the multiple first threaded rods respectively pressed against the top of the multiple horizontal plates, a fourth threaded rod threadedly connected to the inner wall of each of the multiple vertical plates, the outer walls of the multiple fourth threaded rods respectively threadedly connected to the inner wall of the multiple horizontal plates.

[0008] Preferably, the outer wall of the side plate is fixedly connected to a reinforcing block by bolts, and the outer wall of the reinforcing block fits into the groove, and the bottom of the base plate is provided with reinforcing ribs.

[0009] Preferably, a pad is attached to the top of the base plate, and a second threaded rod is threaded to the inner wall of the pad. The outer wall of the second threaded rod is threaded to the inner wall of the base plate, and a first nut is threaded to the outer wall of the second threaded rod. The outer wall of the first nut abuts against the bottom of the base plate.

[0010] Preferably, a curved plate is rotatably connected to the bottom of the base plate, a cover plate is attached to the outer wall of the curved plate, a first support plate is rotatably connected to the top of the cover plate, a second support plate is attached to the bottom of the vertical plate below, and the top side of the second support plate is threadedly connected to the outer wall of the fourth threaded rod below.

[0011] Preferably, the outer wall of the cover plate is abutted against a third threaded rod, and the outer wall of the third threaded rod is threadedly connected to an inclined tube, the end of which is fixedly connected to the bottom of the first support plate.

[0012] Beneficial effects

[0013] This utility model provides a movable stair formwork structure. It has the following advantages: the movable stair formwork structure, through the cooperation of the base plate, side plate, vertical plate, horizontal plate, groove, fourth threaded rod and first threaded rod, can adjust the overall width of the stair treads according to actual use needs, so as to adapt to different building requirements. Moreover, the structure is simple, easy to operate, and the adjustment is easy for workers. It can also improve work efficiency and facilitate the use of workers.

[0014] The pad block can be fixed from the bottom by fixing bolts on the bottom panel. When laying steel bars, it can be placed directly without the need to tie it to the steel bars, which simplifies the operation process and reduces unnecessary labor costs.

[0015] By combining the curved plate, cover plate, inclined tube and third threaded rod, debris can be collected better after the mold is set up, and then quickly cleaned. This avoids the problem of debris inside the mold being difficult to remove quickly after the mold is set up, thus bringing convenience to the staff. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0026] Traditional stair formwork has poor self-adjustment performance. When it is necessary to prefabricate stairs with different step specifications, the overall adjustment is too complicated, resulting in low overall operation and high difficulty of operation. The work intensity of workers is also high, which brings inconvenience to workers.

[0027] In view of this, the present invention provides a movable structure for stair formwork. Through the cooperation of the base plate, side plate, vertical plate, horizontal plate, groove, fourth threaded rod and first threaded rod, the overall width of the stair treads can be adjusted according to actual use needs to suit different building requirements. The structure is simple, easy to operate, and the adjustment is easy for workers. It can also improve work efficiency and facilitate the use of workers.

[0028] Example 1: By Figure 1 , 2 As can be seen from points 3, 5, 6, and 7, a movable stair formwork structure includes a base plate 1. A side plate 2 is fixedly connected to one side of the base plate 1 by bolts. A groove 7 is machined on the upper part of the side plate 2. Multiple connecting plates 3 are pressed against the outer wall of the side plate 2. A fifth threaded rod 20 is threadedly connected to the inner wall of the multiple connecting plates 3. A second nut 21 is threadedly connected to the outer wall of the fifth threaded rod 20. The outer wall of the second nut 21 is pressed against the outer wall of the side plate 2. Multiple horizontal plates 4 are fixedly connected to the bottom of the multiple connecting plates 3. Multiple vertical plates 5 are attached to the outer wall of the multiple horizontal plates 4. The outer walls of the multiple horizontal plates 4 and the multiple vertical plates 5 are attached to the outer wall of the side plate 2. A first threaded rod 6 is threadedly connected to the inner wall of the multiple vertical plates 5. The outer walls of the multiple first threaded rods 6 are pressed against the top of the multiple horizontal plates 4 respectively. A fourth threaded rod 19 is threadedly connected to the inner wall of the multiple vertical plates 5 respectively. The outer walls of the multiple fourth threaded rods 19 are threadedly connected to the inner wall of the multiple horizontal plates 4 respectively.

[0029] In the specific implementation process, it is worth noting that this case does not have one side of the side plate 2 directly attached to the wall. The width of the stair treads can be changed by adjusting the position between the vertical plate 5 and the horizontal plate 4. The first threaded rod 6 and the fourth threaded rod 19 can fix the horizontal plate 4 and the vertical plate 5.

[0030] Furthermore, the outer wall of the side plate 2 is fixedly connected with a reinforcing block 8 by bolts, and the outer wall of the reinforcing block 8 fits into the groove 7. The bottom of the base plate 1 is provided with a reinforcing rib 9.

[0031] In the specific implementation process, it is worth noting that the reinforcing block 8 can improve the strength of the side plate 2 itself and avoid the deformation and damage of the side plate 2 during casting, while the reinforcing rib 9 can improve the strength of the bottom plate 1.

[0032] Furthermore, a pad 10 is attached to the top of the base plate 1, and a second threaded rod 11 is threadedly connected to the inner wall of the pad 10. The outer wall of the second threaded rod 11 is threadedly connected to the inner wall of the base plate 1, and a first nut 12 is threadedly connected to the outer wall of the second threaded rod 11. The outer wall of the first nut 12 is pressed against the bottom of the base plate 1.

[0033] In the specific implementation process, it is worth noting that the workers can use the spacer 10 to carry out the pre-embedding of the steel bars, and after the pouring is completed, the steel bars will not be directly exposed, thus avoiding the phenomenon of steel bar corrosion. After the pouring is completed, the second threaded rod 11 can be removed, and the first nut 12 can improve the stability of the spacer 10.

[0034] Specifically, when using this movable structure of staircase formwork, the workers first erect the base plate 1 on one side of the wall, then install the pad 10, the second threaded rod 11 and the first nut 12, and then pre-embed the reinforcing bars through the pad 10. After that, the side plate 2 is connected and fixed to the base plate 1, and then the horizontal plate 4 and the vertical plate 5 are installed. After all the installations are completed, the pouring operation can be carried out.

[0035] Example 2: From Figure 1 , 2 As can be seen from 4, a curved plate 13 is rotatably connected to the bottom of the base plate 1, a cover plate 14 is attached to the outer wall of the curved plate 13, a first support plate 18 is rotatably connected to the top of the cover plate 14, a second support plate 15 is attached to the bottom of the vertical plate 5 located below, and the top side of the second support plate 15 is threadedly connected to the outer wall of the fourth threaded rod 19 located below.

[0036] In the specific implementation process, it is worth noting that there is a building mold for the stair platform between the second support plate 15 and the first support plate 18, and a building mold for the load-bearing beam between the curved plate 13 and the cover plate 14. When the stair platform is poured, the stair platform and the load-bearing beam can be poured together. When the pouring is not carried out, the construction waste can be collected for easier cleaning.

[0037] Furthermore, a third threaded rod 17 is pressed against the outer wall of the cover plate 14, and an inclined tube 16 is threadedly connected to the outer wall of the third threaded rod 17. The end of the inclined tube 16 is fixedly connected to the bottom of the first support plate 18.

[0038] In the specific implementation process, it is worth noting that the cooperation between the third threaded rod 17 and the inclined tube 16 can limit the cover plate 14 and prevent the cover plate 14 from opening accidentally.

[0039] Specifically, based on the above embodiment 1, when it is necessary to remove the garbage inside the curved plate 13, the worker twists the third threaded rod 17. At this time, the third threaded rod 17 moves along the inner wall of the inclined tube 16. When the third threaded rod 17 moves away from the cover plate 14 by a certain distance, the cover plate 14 can be opened, and then the cleaning work can be carried out.
