Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of pier column construction, and in particular to a modular quick-disassembly construction platform for a ladder cage top and a construction process. Background Art
[0002] Bridge column construction involves high-altitude work. To ensure construction safety, a dedicated scaffolding construction platform must be set up before pouring column concrete. Because the platform's short lifespan and rapid turnover require significant manpower and material resources, setting up the platform is costly. Consequently, half of the construction companies do not set up a dedicated platform during column concrete pouring. Instead, workers directly straddle the formwork or use a simple steel hanging basket attached to the formwork to pour column concrete. This poses a significant safety hazard and violates safety construction requirements. Summary of the Invention
[0003] The technical problem to be solved by the present invention is: in order to solve the technical problems in the prior art, the present invention provides a modular quick-disassembly construction platform and a construction process for the top of a ladder cage.

[0005] The top of the ladder cage of the present invention uses a modular quick-disassembly construction platform. During installation, the construction platform is first placed on the ladder cage, and then the guardrail is inserted onto the construction platform and passed through the construction platform to connect with the ladder cage. While installing the guardrail, the construction platform can be quickly fixed, thereby improving construction efficiency.
[0006] Furthermore, a support plate is provided on the top of the ladder cage, and the support plate is suitable for placing a construction platform.

[0007] Furthermore, the ladder cage is sleeved outside the pier to be cast, a construction groove for accommodating the pier is provided in the ladder cage, and a climbing staircase is provided on the side wall of the construction groove.
[0008] Furthermore, the guardrail includes a main guardrail and a side guardrail, and the main guardrail and the side guardrail are alternately arranged along the circumference of the construction platform. There are four main guardrails and four side guardrails, and the angle between the projections of adjacent main guardrails and side guardrails in the vertical direction is 45 degrees; the side wall of the construction platform includes a main plane and a side plane, and the main plane and the side plane are alternately arranged along the circumference of the construction platform. There are four main guardrails and four side planes, and the angle between the projections of adjacent main planes and side planes in the vertical direction is 45 degrees.
[0009] Furthermore, a mounting rod is fixedly connected to the support plate, and a guide rod is hinged on the mounting rod. Four guide rods are provided, and correspond one to one with four side planes. The guide rod has a guiding state and a fixed state. When the guide rod is in the guiding state, the guide rod is tilted relative to the support plate to facilitate contact with the side plane to guide the lifting of the construction platform. When the guide rod is in the fixed state, the guide rod contacts the side plane and is connected to the side guardrail.
[0010] Furthermore, a limit rod is provided on the guide rod, and when the guide rod is in the guiding state, the limit rod contacts the top surface of the support plate; the connection position between the limit rod and the guide rod is higher than the hinge position between the guide rod and the mounting rod, so that when there is no external force acting on the guide rod, the bottom of the guide rod is in a tilted state.
[0011] Furthermore, a mounting plate is detachably connected to the main guardrail, a vibrating motor is mounted on the mounting plate, and a storage roller is also provided on the mounting plate for storing the vibrating rod.
[0012] Furthermore, a storage shaft is provided on the mounting plate, and the storage shaft is used to store cables.
[0013] Furthermore, the mounting plate is detachably connected to the main guardrail via a connector, and the mounting plate can slide relative to the main guardrail. The connector is used to fix the mounting plate relative to the main guardrail.
[0014] Furthermore, the connecting piece includes a connecting hook and a fixing nut, the connecting hook is hooked on the main guardrail, the end of the connecting hook away from the main guardrail passes through the mounting plate and is threadedly connected to the fixing nut, and the fixing nut conflicts with the mounting plate.

Hook the connecting hook onto the main guardrail, lock the mounting plate onto the main guardrail with the fixing nut, and securely connect the guide rod to the side guardrail with the bolts.
[0016] The beneficial effects of the present invention are: 1. During installation, first place the construction platform on the ladder cage, then insert the guardrail on the construction platform, and pass it through the construction platform to connect with the ladder cage. While installing the guardrail, the construction platform can be quickly fixed to improve construction efficiency.
[0017] 2. By switching the guide rod between the guiding state and the fixed state, when the guide rod is in the guiding state, it is convenient to guide the construction platform, thereby facilitating the construction platform to be quickly and accurately positioned; when the guide rod is in the fixed state, the guide rod contacts the side plane of the construction platform, facilitating the positioning of the construction platform, and at the same time, the guide rod is connected to the side railing to improve the reliability of the construction platform installation; 3.

[0026] The invention discloses a modular quick-disassembly construction platform for the top of a ladder cage.
[0027] Reference Figures 1 to 4 A modular, quick-detachable construction platform for a ladder cage top comprises a ladder cage 1 and a construction platform 2 positioned above the cage 1. The construction platform 2 is provided with a guardrail, the bottom of which is fixedly connected to a fixing rod 25. The fixing rod 25 passes through the construction platform 2 and is detachably connected to the ladder cage 1. During installation, the construction platform 2 is first placed on the ladder cage 1, and then the guardrail is inserted onto the construction platform 2 and connected through the construction platform 2 to the ladder cage 1. This allows the construction platform 2 to be quickly fixed while the guardrail is being installed, improving construction efficiency.
[0028] It should be noted that the ladder cage 1 is mounted outside the pier to be cast. A construction trough for accommodating the pier is located within the cage 1, with a climbing staircase fixedly connected to the sidewalls of the trough. While the conventional ladder cage 1 is mounted on one side of the pier, supporting the construction platform 2 from the side and providing access for the platform to ascend and descend, this solution mounts the cage 1 directly outside the pier, providing better support for the construction platform 2.
[0029] Specifically, the top of the ladder cage 1 is fixedly connected to a support plate 11, which is suitable for placing the construction platform 2. A connecting pipe 111 is welded to the bottom surface of the support plate 11. A fixing rod 25 passes through the support plate 11 and the connecting pipe 111 and is threadedly connected to a locking nut 26. The locking nut 26 contacts the bottom surface of the connecting pipe 111 to lock the fixing rod 25. The guardrail includes a horizontal bar 211 and a vertical bar 212. There are multiple horizontal bars 211 in the vertical direction. The horizontal bars 211 and the vertical bars 212 are combined to ensure the reliability of the guardrail. The lowest horizontal bar 211 contacts the bottom surface of the construction platform 2. The locking nut 26 is used to tighten the horizontal bar 211 and the construction platform 2, thereby simultaneously achieving the fixation of the construction platform 2 and the guardrail.
[0030] More specifically, the guardrail includes a main guardrail 21 and a side guardrail 22, which are alternately arranged along the circumference of the construction platform 2. There are four main guardrails 21 and four side guardrails 22, and the angle between the projections of adjacent main guardrails 21 and side guardrails 22 in the vertical direction is 45 degrees; the side wall of the construction platform 2 includes a main plane 23 and a side plane 24, which are alternately arranged along the circumference of the construction platform 2. There are four main guardrails 21 and four side guardrails 22, and the angle between the projections of adjacent main planes 23 and side planes 24 in the vertical direction is 45 degrees.
[0031] Furthermore, a mounting rod 14 is fixedly connected to the support plate 11, and a guide rod 15 is hingedly connected to the mounting rod 14. Four guide rods 15 are provided, and each corresponds to the four side planes 24. The guide rods 15 have a guiding state and a fixed state. When the guide rods 15 are in the guiding state, the guide rods 15 are tilted relative to the support plate 11 to facilitate contact with the side planes 24 to guide the lifting of the construction platform 2. When the guide rods 15 are in the fixed state, the guide rods 15 are connected to the side guardrails 22.
[0032] More specifically, a limiting rod 16 is fixedly connected to the guide rod 15. When the guide rod 15 is in the guiding state, the limiting rod 16 contacts the top surface of the support plate 11. The connection position between the limiting rod 16 and the guide rod 15 is higher than the hinge position between the guide rod 15 and the mounting rod 14, so that when there is no external force acting on the guide rod 15, the bottom of the guide rod 15 is in a tilted state.
[0033] In addition, the main guardrail 21 is detachably connected to a mounting plate 3, on which a vibrating motor 31 is mounted. A storage roller 32 is also fixedly connected to the mounting plate 3 for storing the vibrating rod. A storage shaft 33 is fixedly connected to the mounting plate 3 for storing cables.
[0034] Specifically, the mounting plate 3 is detachably connected to the main guardrail 21 via a connector 34 , and the mounting plate 3 can slide relative to the main guardrail 21 . The connector 34 is used to fix the mounting plate 3 relative to the main guardrail 21 .
[0035] More specifically, the connecting member 34 includes a connecting hook 341 and a fixing nut 342. The connecting hook 341 is hooked on the main guardrail 21. The end of the connecting hook 341 away from the main guardrail 21 passes through the mounting plate 3 and is threadedly connected to the fixing nut 342. The fixing nut 342 conflicts with the mounting plate 3.
[0036] Working principle: During installation, first place the construction platform 2 on the ladder cage 1, then insert the guardrail on the construction platform 2, and pass it through the construction platform 2 to connect with the ladder cage 1. While installing the guardrail, the construction platform 2 can be quickly fixed to improve construction efficiency.
[0037] By switching the guide rod 15 between the guiding state and the fixed state, when the guide rod 15 is in the guiding state, it is convenient to guide the construction platform 2, thereby facilitating the construction platform 2 to be quickly and accurately positioned; when the guide rod 15 is in the fixed state, the guide rod 15 contacts the side plane 24 of the construction platform 2, facilitating the positioning of the construction platform 2, and at the same time, the guide rod 15 is connected to the side railing, thereby improving the reliability of the installation of the construction platform 2; The setting of the limiting rod 16 makes it easy for the guide rod 15 to be in the guiding state by relying on gravity when there is no external force acting on the guide rod 15, and can support the guide rod 15 when it is in the guiding state.
[0038] A construction process, based on the above-mentioned modular quick-disassembly construction platform for the top of the ladder cage, includes the following steps: S1. Hoist the construction platform 2 above the ladder cage 1 using a lifting device, and make the construction platform 2 contact the guide rod 15 in the guide state. Then slowly lower the construction platform 2 and limit the construction platform 2 by the guide rod 15. S2. After the construction platform 2 falls on the support plate 11, the guide rod 15 is in a fixed state under the action of the construction platform 2 to limit the construction platform 2; S3. Pass the guardrail fixing rod 25 through the construction platform 2 and the connecting pipe 111, thread the locking nut 26 into the fixing rod 25, and make the locking nut 26 contact the bottom surface of the connecting pipe 111; S4. Hook the connecting hook 341 onto the main guardrail 21, lock the mounting plate 3 onto the main guardrail 21 through the fixing nut 342, and fix the guide rod 15 to the side guardrail 22 through bolts.
[0039] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
