Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically to a modular staircase formwork that also serves as a pedestrian access passage. Background Technology

[0002] Staircase formwork is an indispensable component in building construction. Currently, existing staircase formwork presents numerous problems during construction. Due to construction needs, personnel must pass through before the staircase formwork is poured; however, in existing staircase formwork structures, personnel often have to step on the uprights. For example, Chinese Patent CN222810450U discloses a staircase formwork device that uses tie rods to fix the formwork components. While this reduces pouring displacement, it lacks a dedicated passageway, requiring construction workers to still step on the uprights. Over time, frequent stepping can cause deformation of the uprights, affecting not only the formwork's performance and the quality of subsequent staircase pouring but also posing significant safety hazards for personnel, potentially leading to accidents and challenging construction safety management. Therefore, there is an urgent need to improve existing staircase formwork to address these issues. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a modular staircase formwork that also serves as a passageway for people, in order to solve the problem that the existing staircase formwork is prone to deformation of the uprights and poses safety hazards when people pass through.

[0004] To achieve the aforementioned objectives of this utility model, the technical solution adopted is as follows: A modular, prefabricated staircase formwork that also serves as an access passageway includes a bottom formwork, side formwork, and multiple uprights. Side formwork is fixed to both sides of the bottom formwork. The staircase is characterized by including stepped treads. Multiple slots are formed along the length of each side formwork, and the ends of the uprights are engaged in these slots. The bottom formwork comprises a spliced ​​wooden formwork and a steel formwork. Trapezoidal protrusions for forming stair drip grooves are fixed along the length of the steel formwork. The treads are mounted on the uprights, with both ends fixed to the bottom formwork. Each tread includes multiple sequentially connected L-shaped plates. Pads are fixed at the bottom of each tread where it contacts the uprights. An inclined baffle is provided at the upper outer side of each side formwork. Through holes are formed along the length of each upright, and clamping plates are fixed at both ends. Pull-through screws are installed within the through holes, and butterfly clips are threaded onto both ends of the pull-through screws extending beyond the uprights. The butterfly clips at both ends of the pull-through screws secure the two side formworks and the two inclined baffles respectively located at the upper outer sides of the two side formworks together.

[0005] Furthermore, the height of the pad is 10-15mm. The pad is designed so that the horizontal part of the tread is higher than the vertical part of the corresponding position, which makes it convenient to insert the trowel under the tread to smooth the cement when pouring the steps.

[0006] Furthermore, multiple sleeves are fixed on both sides of the pedal, and protective railings are inserted into the sleeves.

[0007] Furthermore, the shape of the bayonet matches the end of the upright plate, and a rubber buffer pad is provided inside the bayonet to reduce friction and vibration between the upright plate and the side template.

[0008] Furthermore, the horizontal surface of the pedal is provided with anti-slip texture.

[0009] The beneficial effects of this utility model are: 1. This utility model provides a dedicated passage for construction workers by setting up stepped treads, avoiding people stepping on the uprights and effectively preventing the uprights from deforming due to frequent stepping, ensuring the performance of the formwork and the quality of subsequent stair pouring, while greatly reducing the safety hazards of personnel passage.

[0010] 2. The pad is designed so that the horizontal part of the tread is higher than the vertical part of the corresponding position, which makes it easier to insert the trowel under the tread to smooth the cement when pouring the steps, thus improving construction efficiency and quality.

[0011] 3. The sleeves and guardrails installed on both sides of the pedal further enhance the safety of personnel passage.

[0012] 4. The rubber buffer pads installed inside the bayonet reduce friction and vibration between the upright plate and the side template, extending the service life of the template.

[0013] 5. The anti-slip texture on the horizontal part of the pedal increases the friction when people walk, preventing slips and improving the safety of passage. Attached Figure Description

[0018] Please see Figure 1-4 A modular, prefabricated staircase template that also serves as an access passageway includes a bottom template 1, side templates 2, and multiple uprights 3. Side templates 2 are fixed to both sides of the bottom template 1. The template is characterized by including stepped treads 4. Multiple slots 21 are formed along the length of each side template 2, and the two ends of each upright 3 are engaged in the corresponding slots 21. The bottom template 1 comprises a wooden template 11 and a steel template 12 assembled together. Trapezoidal protrusions 13 for forming a drip groove in the staircase are fixed along the length of the steel template 12. The treads 4 are mounted on the uprights 3, and the two ends of each tread are fixed... Fixed on the bottom template 1, the pedal 4 includes multiple L-shaped plates connected in sequence. The bottom of the pedal 4 is fixed with a pad 41 at the position where it contacts the upright plate 3. The upper outer side of the side template 2 is provided with a slanted baffle 5. The upright plate 3 has a through hole 31 along its length direction, and the two ends of the upright plate 3 are fixed with a clamping plate 32. A pull screw 6 is installed in the through hole 31. The two ends of the pull screw 6 extend out of the upright plate 3 and are threaded with a butterfly clip 7. The two side templates 2 and the two slanted baffles 5 respectively provided on the upper outer side of the two side templates 2 are clamped together by the butterfly clips 7 provided on the two ends of the pull screw 6.

[0019] The height of the pad 41 is 10-15mm. The pad 41 is set so that the horizontal part of the tread 4 is higher than the vertical plate 3 at the corresponding position, which makes it convenient to insert the trowel under the tread 4 to smooth the cement when pouring the steps.

[0020] Multiple sleeves 42 are fixed on both sides of the pedal 4, and protective railings 8 are inserted into the sleeves 42.

[0021] The shape of the bayonet 21 matches the end of the upright plate 3, and a rubber buffer pad 22 is provided inside the bayonet 21 to reduce friction and vibration between the upright plate 3 and the side template 2.

[0022] The horizontal surface of the pedal 4 is provided with anti-slip texture.

[0023] Working Principle: When using this invention, first, the bottom formwork 1 is installed on the foundation of the staircase. Then, the side formwork 2 is fixed to both sides of the bottom formwork 1. Next, the two ends of the upright plate 3 are secured in the slots 21 on the side formwork 2. Then, the tread plate 4 is installed on the upright plate 3, and the two ends of the tread plate 4 are fixed to the bottom formwork 1. After installation, tie rods 6 are installed in the through holes 31, and the two side formwork 2 and the inclined baffle 5 are secured together using butterfly clips 7. During construction, workers can pass up and down using the tread plate 4, avoiding stepping on the upright plate 3, thus ensuring the stability and service life of the upright plate 3. When pouring the steps, due to the pad 41, the horizontal part of the tread plate 4 is higher than the upright plate 3, making it convenient for workers to insert a trowel under the tread plate 4 to smooth the cement. At the same time, the guardrails 8 on both sides of the tread plate 4 and the anti-slip texture on the surface further improve the safety of personnel passage.
