Description

Technical Field

[0001] This utility model belongs to the field of concrete retaining wall construction technology, specifically relating to a steel formwork construction platform for concrete retaining walls. Background Technology

[0002] When pouring concrete retaining walls, it is usually necessary to erect a construction platform on the steel formwork of the retaining wall to provide workers with a stable working surface at height and prevent the risk of falling.

[0003] Most current construction platforms are designed in a modular fashion, requiring multiple reassemblies on the construction site before they can be put into use. For example, in the prior art, Chinese utility model patent document with authorization announcement number CN220847158U discloses a construction platform for personnel on the side of a template, in which the first-layer platform unit, the second-layer platform unit, and the diagonal bracing are designed in a modular fashion. During installation, not only do they need to be connected to the template, but the first-layer platform unit, the second-layer platform unit, the railing, and the diagonal bracing also need to be reassembled multiple times, resulting in a long installation time. In addition, the railing is fixed to the top of the first-layer platform unit, which requires a lot of space during transportation and storage.

[0004] Therefore, it is necessary to design a concrete retaining wall steel formwork construction platform that saves installation time, has high space utilization due to its foldable design, and is convenient for transportation and storage to solve the current technical problems.

[0024] like Figures 1 to 5As shown, the concrete retaining wall steel formwork construction platform includes a platform base plate 1, a guardrail assembly 2, and a diagonal bracing assembly 3. The platform base plate 1 has a base frame 11, a mesh plate 12 is provided on the top of the base frame 11, and connecting plates 13 are provided on both sides of the base frame 11. The guardrail assembly 2 has a side support frame 22, and L-shaped connecting rods 21 are fixedly provided on both sides of the side support frame 22. The L-shaped connecting rods 21 are rotatably connected to the side of the base frame 11. The diagonal bracing assembly 3 has a threaded rod 34, and support pipes 33 are threaded to both ends of the threaded rod 34. A hinge seat 31 is fixedly provided at the end of one support pipe 33, and an mounting seat 32 is fixedly provided at the end of the other support pipe 33. The hinge seat 31 is rotatably connected to the side of the base frame 11. A locking mechanism 4 is provided on the inner side of the base frame 11. When the side support frame 22 is perpendicular to the base frame 11, the locking mechanism 4 locks or releases the L-shaped connecting rods 21 from the base frame 11. In this embodiment, the connecting plates... The end of component 13 is fixedly connected to the steel template via a bolt and nut mechanism. Then, the length of the diagonal brace component 3 is adjusted, and the mounting base 32 of the diagonal brace component 3 is fixedly connected to the steel template via a bolt and nut mechanism. The side support frame 22 is flipped so that it is perpendicular to the bottom frame 11. At this time, the L-shaped connecting rod 21 is locked to the bottom frame 11 via the locking mechanism 4, thus completing the installation of the construction platform on the outside of the steel template. The folding design between the guardrail component 2, the diagonal brace component 3, and the platform base plate 1 saves installation time. Before transportation and storage, the guardrail component 2 and the platform base plate 1 can be folded in half, and the diagonal brace component 3 can be folded at both ends of the platform base plate 1, which can improve space utilization and facilitate transportation and storage. The telescopic diagonal brace component 3 is not only easy to fold, but also can be adapted to the connection holes with different vertical spacing on the outside of different steel templates, with a wide range of adaptability, which is conducive to adaptive installation.

[0025] In the above embodiment, the lead screw 34 has two external threads with opposite helical directions, and the support tube 33 has an internal thread that matches the lead screw 34. When the lead screw 34 is rotated relative to the support tube 33, the thread structure between the lead screw 34 and the support tube 33 can drive the lead screw 34 to move relative to the support tube 33, thereby realizing the length adjustment of the diagonal brace assembly 3.

[0026] In some embodiments, such as Figure 3 and 4As shown, the end of the L-shaped connecting rod 21 is provided with a locking hole 211 that matches the locking mechanism 4; the locking mechanism 4 has a slide cylinder 43 fixedly installed inside the bottom frame 11, and an end plate 44 is provided on the end of the slide cylinder 43 facing away from the bottom frame 11. A locking bolt 41 that matches the locking hole 211 is slidably installed inside the slide cylinder 43. A baffle 42 that is slidably installed inside the slide cylinder 43 is fixedly installed on the locking bolt 41. A spring 46 is fitted on the outside of the locking bolt 41 between the baffle 42 and the end plate 44; when the locking bolt 41 is pulled, it retracts into the bottom frame 11. The guardrail assembly 2 is rotated so that it is perpendicular to the bottom frame 11, and the locking bolt 41 is released. Under the elastic force of the spring 46, the locking bolt 41 is inserted into the locking hole 211, locking the L-shaped connecting rod 21 and the bottom frame 11, providing support for the guardrail assembly 2 and keeping it in a vertical state.

[0027] In some embodiments, a pull ring 45 is fixedly provided on one end of the locking bolt 41 away from the locking hole 211, and the locking bolt 41 can be easily pulled by the pull ring 45.

[0028] In some embodiments, the L-shaped connecting rod 21 is provided with a locking groove 212 that matches the locking bolt 41. When the side support frame 22 is rotated to a state parallel to the bottom frame 11, one side of the side support frame 22 abuts against the top of the bottom frame 11, and the locking bolt 41 can be inserted into the locking groove 212 to lock the folded guardrail assembly 2 and the platform base plate 1, ensuring stability during transportation.

[0029] In some embodiments, fixed railings 23 are evenly arranged inside the side support frame 22, and movable railings 24 are arranged between the fixed railings 23. A crossbar 25 is fixedly arranged at the top of the movable railing 24, and a support rod 26 is fixedly arranged at the bottom of the movable railing 24. The support rod 26 is slidably connected to the fixed railings 23. An adjustment mechanism for adjusting the height of the movable railings 24 is provided inside the side support frame 22. The height of the movable railings 24 can be adjusted by the adjustment mechanism to meet different protection height requirements. At the same time, when folded, the movable railings 24 can be basically tucked into the side support frame 22, improving space utilization and facilitating transportation and storage.

[0030] In some embodiments, the adjustment mechanism has a screw 27 centrally located inside the side support frame 22, and a clearance hole matching the screw 27 is provided on the support rod 26. A support nut 28 is fitted on the outside of the screw 27 below the support rod 26. By rotating the support nut 28, the threaded structure between the support nut 28 and the screw 27 can push the support rod 26 to move up and down, thereby adjusting the height of the movable railing 24 to meet different protection height requirements.

[0031] In some embodiments, a handle 35 is slidably disposed on the lead screw 34. The handle 35 is a rectangular frame structure. The lead screw 34 has through holes that match the two short sides of the handle 35. The short sides of the handle 35 are slidably connected to the lead screw 34. The handle 35 slides inside the lead screw 34. When folding, the main body of the handle 35 can be moved away from the platform base plate 1, so as to avoid interference between the handle 35 and the platform base plate 1 when folding.
