Foldable capping beam construction platform

Abstract

The utility model discloses a foldable cover beam construction platform which comprises a column body, a frame body fixedly installed on the outer wall of the column body, a bolt arranged in the frame body in a threaded and sleeved mode and a machining assembly arranged above the frame body, and the machining assembly comprises a telescopic assembly arranged above the frame body. When the device needs to be broadened for use, a rotating handle is rotated to drive an opposite threaded rod to rotate along with the rotating handle, the rotating opposite threaded rod drives the two sleeve blocks to move oppositely under the limitation of the rotating handle due to the fact that the outer walls of the sleeve blocks and the interiors of the sleeve plates slide in an attached mode, and due to the fact that the ends of the connecting plates are hinged to the sleeve blocks and the connecting blocks, and the connecting blocks and the outer walls of the broadening plates are fixedly installed, the broadening effect is good. And under the limitation, the sleeve blocks moving oppositely push the connecting blocks and the widening plates through the connecting plates, so that the limiting grooves formed in the outer walls of the two widening plates slide on the outer walls of the limiting strips fixedly mounted on the inner walls of the sleeve plates, and the two widening plates move oppositely to widen the platform.

Description

Technical Field

[0001] This utility model relates to the technical field of cap beam construction platforms, specifically a foldable cap beam construction platform. Background Technology

[0002] A girder construction platform is a temporary structure used in building construction for girder construction. It provides a stable working surface for construction workers to carry out operations such as girder installation, rebar tying, formwork installation, and concrete pouring. A foldable girder construction platform is a temporary platform facility specifically designed for bridge construction. It provides construction workers with a safe and stable working environment, ensuring the smooth progress of girder pouring, installation, and adjustment.

[0003] As disclosed in Chinese Patent CN221740954U, a foldable cap beam construction platform is constructed by using clamps to connect the bridge piers and bolting between connecting plates. The connecting plates provide support for the crossbeams and ensure their stability through studs and mounting holes. The longitudinal beams are connected to the crossbeams via slots, and the reinforcing ribs on both sides improve the support performance of the platform and enhance the strength of the construction walking surface. The railings can be rotated and folded onto the platform via hinges, thereby reducing the space required for transporting parts. During construction, the railings rotate and stand upright, allowing the limiting plate to fit against the side wall of the platform and be bolted together to achieve stability.

[0004] While the railings of this structure can be folded, the platform cannot be widened, making it inflexible in use. Therefore, we propose a foldable cap beam construction platform that can widen the platform to broaden its applicability and improve the platform's flexibility in use. Utility Model Content

[0005] The purpose of this invention is to provide a foldable cap beam construction platform to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a foldable cap beam construction platform, including a column, a frame fixedly installed on the outer wall of the column, bolts threaded inside the frame, and a processing component set above the frame, the processing component including a telescopic component set above the frame, and a folding component set on the outside of the telescopic component.

[0007] Preferably, the telescopic assembly includes a sleeve plate fixedly installed on the top surface of the frame, a limit strip fixedly installed on the inner wall of the sleeve plate, a widening plate slidably provided on the outer wall of the limit strip, a limit groove formed on the outer wall of the widening plate, a counter-threaded rod rotatably connected inside the sleeve plate, a handle fixedly installed at the end of the counter-threaded rod, a sleeve block sleeved on the outer wall of the counter-threaded rod, a connecting plate hinged inside the sleeve block, and a connecting block hinged at the end of the connecting plate away from the sleeve block.

[0008] Preferably, the folding assembly includes a fixing block fixedly installed on the top surface of the widening plate, a rotating column rotatably connected inside the fixing block, a guardrail fixedly installed at the end of the rotating column, a locking plate snapped into the inside of the rotating column, a pull rod fixedly installed on the outer wall of the locking plate, a spring sleeved on the outer wall of the pull rod, and an L-shaped frame slidably arranged on the outer wall of the pull rod.

[0009] Preferably, there are two widening plates, symmetrically distributed around the center line of the sleeve plate, which can widen the platform under their constraints.

[0010] Preferably, the connecting block is fixedly installed on the outer wall of the widening plate, and the end of the connecting plate is hinged to the connecting block and the sleeve block. Under the internal sliding restriction of the sleeve block and the sleeve plate, the rotating opposing threaded rod can drive the two sleeve blocks to move in opposite directions. The connecting plate pushes the widening plate outward from the sleeve plate to achieve the effect of widening the platform.

[0011] Preferably, the card plate engages with the rotating column, and the end of the rotating column is provided with a cross groove, which restricts the engagement of the vertical guardrail to protect the operator.

[0012] Preferably, the L-shaped frame is fixedly installed on the outer wall of the widening plate, and the pull rod is slidably disposed inside the L-shaped frame. Under the restriction of the L-shaped frame, the pull rod is released, and under the elastic restriction of the spring sleeved on the outer wall of the pull rod, the clamping plate is pushed towards the rotating column.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This foldable cap beam construction platform is composed of a telescopic assembly. When the cap beam construction platform needs to be widened, the handle is turned, which drives the opposing threaded rod to rotate. Due to the sliding contact between the outer wall of the sleeve block and the inside of the sleeve plate, the rotating opposing threaded rod drives the two sleeve blocks to move in opposite directions. Since the end of the connecting plate is hinged to the sleeve block and the connecting block, and the connecting block is fixedly installed on the outer wall of the widening plate, the opposing moving sleeve blocks push the connecting block and the widening plate through the connecting plate. This causes the limiting grooves on the outer walls of the two widening plates to slide on the outer wall of the limiting strip fixedly installed on the inner wall of the sleeve plate, causing the two widening plates to move in opposite directions to widen the platform. This structure can widen the platform, and the retracted widening plate can reduce the size of the platform, making it easier to carry.

[0015] 2. This foldable cap beam construction platform consists of a folding assembly. When the platform needs to be moved, the widening plate is retracted into the sleeve plate. At this time, pulling the pull rod compresses the spring sleeved on the outer wall of the pull rod by the clamp plate fixed at its end, so that the clamp plate is no longer engaged with the end of the rotating column. Then, the guardrail is rotated so that it rotates around the rotating connection between the rotating column and the fixed block as the rotation center, and the guardrail is rotated towards the widening plate to fold, reducing the platform volume and making it easier to carry. When the platform needs to be used, the guardrail is rotated so that it is perpendicular to the top surface of the widening plate. The pull rod is released, and under the elastic action of the spring, the clamp plate is pushed towards the rotating column, so that the clamp plate engages with the slot at the end of the rotating column, restricting the guardrail. The guardrail can protect the operator. Attached Figure Description

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] Example 1: A preferred embodiment of the foldable cap beam construction platform provided by this utility model Figures 1 to 6 As shown: A foldable cap beam construction platform, including column 1;

[0025] A frame 2 is fixedly installed on the outer wall of column 1;

[0026] Bolts 3 are threaded inside the frame 2;

[0027] The processing component 4 is located above the frame 2. The processing component 4 includes a telescopic component 41 located above the frame 2. The telescopic component 41 includes a sleeve plate 411 fixedly installed on the top surface of the frame 2. A limit strip 412 is fixedly installed on the inner wall of the sleeve plate 411. A widening plate 413 is slidably provided on the outer wall of the limit strip 412. A limit groove 414 is opened on the outer wall of the widening plate 413. A counter-threaded rod 419 is rotatably connected inside the sleeve plate 411. A handle 415 is fixedly installed at the end of the counter-threaded rod 419. A sleeve block 418 is sleeved on the outer wall of the counter-threaded rod 419. A connecting plate 417 is hingedly connected inside the sleeve block 418. A connecting block 416 is hingedly connected to the end of the connecting plate 417 away from the sleeve block 418.

[0028] In this embodiment, when the construction platform of the cap beam needs to be widened, the handle 415 is rotated, which drives the opposing threaded rod 419 to rotate accordingly. Since the outer wall of the sleeve block 418 slides in close contact with the inside of the sleeve plate 411, under its restriction, the rotating opposing threaded rod 419 drives the two sleeve blocks 418 to move in opposite directions. Since the end of the connecting plate 417 is hinged to the sleeve block 418 and the connecting block 416, and the connecting block 416 is fixedly installed on the outer wall of the widening plate 413, under its restriction, the opposing sleeve blocks 418 push the connecting block 416 and the widening plate 413 through the connecting plate 417, so that the limiting grooves 414 opened on the outer wall of the two widening plates 413 slide on the outer wall of the limiting strip 412 fixedly installed on the inner wall of the sleeve plate 411, so that the two widening plates 413 move in opposite directions to widen the platform. This structure can widen the platform, and the shrinking widening plate 413 can reduce the size of the platform and make it easier to carry.

[0029] Furthermore, there are two widening plates 413, symmetrically distributed around the center line of the sleeve plate 411, which can widen the platform under their constraints.

[0030] Furthermore, the connecting block 416 is fixedly installed on the outer wall of the widening plate 413, and the end of the connecting plate 417 is hinged to the connecting block 416 and the sleeve block 418. Under the internal sliding restriction of the sleeve block 418 and the sleeve plate 411, the rotating opposing threaded rod 419 can drive the two sleeve blocks 418 to move in opposite directions. The connecting plate 417 pushes the widening plate 413 towards the outside of the sleeve plate 411 to achieve the effect of widening the platform.

[0031] Example 2: Based on Example 1, a preferred embodiment of the foldable cap beam construction platform provided by this utility model is as follows: Figures 1 to 6As shown: The folding assembly 42 includes a fixing block 421 fixedly installed on the top surface of the widening plate 413. A rotating column 426 is rotatably connected inside the fixing block 421. A guardrail 427 is fixedly installed at the end of the rotating column 426. A locking plate 425 is snapped into the rotating column 426. A pull rod 423 is fixedly installed on the outer wall of the locking plate 425. A spring 424 is sleeved on the outer wall of the pull rod 423. An L-shaped frame 422 is slidably arranged on the outer wall of the pull rod 423.

[0032] In this embodiment, when the transfer platform is needed, the widening plate 413 is retracted into the sleeve plate 411. At this time, the pull rod 423 is pulled, and the clamping plate 425 fixedly installed at its end compresses the spring 424 sleeved on the outer wall of the pull rod 423, so that the clamping plate 425 is no longer engaged with the end of the rotating column 426. At this time, the guardrail 427 is rotated, so that the guardrail 427 rotates around the rotating connection between the rotating column 426 and the fixing block 421 as the rotation center, and the guardrail 427 is rotated towards the widening plate 413 to fold, reduce the volume of the platform, and make it easier to carry. When the platform needs to be used, the guardrail 427 is rotated so that it is perpendicular to the top surface of the widening plate 413. The pull rod 423 is released, and under the elastic action of the spring 424, the clamping plate 425 is pushed towards the rotating column 426, so that the clamping plate 425 is engaged with the end slot of the rotating column 426, restricting the guardrail 427. The guardrail 427 can protect the operator.

[0033] Furthermore, the card plate 425 is engaged with the rotating column 426. The end of the rotating column 426 is provided with a cross groove, which can be used to engage and restrict the vertical guardrail 427 to protect the operator.

[0034] In addition, the L-shaped frame 422 is fixedly installed on the outer wall of the widening plate 413, and the pull rod 423 is slidably installed inside the L-shaped frame 422. Under the restriction of the L-shaped frame 422, the pull rod 423 is released, and under the elastic restriction of the spring 424 sleeved on the outer wall of the pull rod 423, the clamping plate 425 is pushed towards the rotating column 426.

[0035] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
