Description

Technical Field

[0001] This invention relates to the field of steel structure construction technology, specifically to a mobile installation device and construction method for steel structure floor decking. Background Technology

[0002] In the renovation or expansion of industrial plants, it is often necessary to add steel structure mezzanines or bungalows inside. Such construction often faces a key technical challenge: the clearance between the top of the new steel structure and the original roof of the plant is very narrow, making it impossible for traditional large hoisting equipment (such as truck cranes and tower cranes) to enter the space for operation.

[0003] Currently, the conventional solution to this problem is manual handling. However, truss floor slabs are large and heavy, and manual handling has the following significant drawbacks: 1. Extremely low efficiency: slow transportation speed, which seriously slows down the project progress.

[0004] 2. High safety risks: Workers carrying heavy objects over long distances on steel beams without a complete working platform are at high risk of falling from heights, being struck by falling objects, and other safety accidents.

[0005] 3. Quality is difficult to guarantee: Manual handling can easily lead to deformation of the floor deck and damage to the galvanized layer, affecting the quality of subsequent concrete pouring.

[0006] 4. High labor intensity: It requires high physical fitness from workers and the working environment is harsh.

[0007] Therefore, the existing floor decking installation methods still have room for improvement and need to be optimized to complete the installation more safely, efficiently, and economically. Thus, a more reasonable technical solution is needed to address the technical problems existing in the current technology. Summary of the Invention

[0008] This invention discloses a mobile installation device and construction method for steel structure floor decking. It utilizes the steel beams of the newly constructed structure itself as load-bearing and walking tracks to realize the mechanized aerial transfer of floor decking. The floor decking is transferred and transported to the predetermined installation position by moving the support frame through the track and the movable frame. This ensures the convenience and reliability of the operation during the installation and construction process, avoids a large amount of manpower, and eliminates safety hazards.

[0009] To achieve the above objectives, the mobile installation device disclosed in this invention can adopt the following solution: A mobile installation device for steel structure floor decking includes a set of relatively parallel conveying tracks, on which a conveying seat is provided; the conveying seat travels along the conveying tracks and drives the load-bearing frame to move synchronously, and the load-bearing frame is provided with a number of lifting components for lifting the floor decking, the lifting components are spaced apart along the length direction of the load-bearing frame and slide back and forth along the length direction of the load-bearing frame.

[0010] The aforementioned mobile installation device is connected and fixed to a steel structure via a conveyor rail, which serves as a load-bearing structure. This allows the conveyor seat to move back and forth on the rail, carrying the load-bearing frame to pick up and transfer floor slabs. Once the slabs arrive at the designated location, they are placed and fixed in place. This greatly reduces the risks associated with manual handling and improves the stability and reliability of the construction.

[0011] Furthermore, the conveyor seat can be constructed in various forms, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the conveyor seat is equipped with at least one set of traveling wheels and one set of stabilizing wheels. The traveling wheels roll along the side of the conveyor track, and the stabilizing wheels roll along the bottom of the rail head of the conveyor track. The conveyor seat slides in contact with the top surface of the conveyor track. When adopting the above scheme, the conveyor track can be an I-beam track, with the traveling wheels abutting against the sides of the I-beam track and the stabilizing wheels abutting against the bottom of the I-beam track.

[0012] Furthermore, the support frame, used to carry the lifting assembly, can be constructed in various forms, and its specific structure is not limited to one particular type. Here, we optimize and propose one feasible option: the support frame includes a U-shaped track frame spanning two conveyor seats, and the lifting assembly is mounted on the track frame and moves reciprocally along it. In this configuration, the track frame is fixedly connected to the conveyor seats, which can be achieved through welding or fasteners.

[0013] Furthermore, the load-bearing frame can take various forms, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the load-bearing frame includes uprights mounted on the conveyor seat, with the uprights connected by crossbeams, and the lifting assembly is fitted onto the crossbeams. In this scheme, the uprights and crossbeams are welded together.

[0014] Furthermore, the lifting component can adopt various schemes, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the lifting component includes a sliding seat, and a lifting hoist is arranged below the sliding seat. When the above scheme is adopted, the sliding seat is sleeved with the crossbar, and a driver can be set on the sliding seat. The driver drives the sliding gear to rotate, and the sliding gear meshes with the crossbar, thereby realizing the reciprocating sliding of the sliding seat on the crossbar.

[0015] Furthermore, to ensure the smooth installation of the floor decking, the structure of the conveyor seat can be optimized. Its structure is not limited to a single design. Here, one feasible option is proposed: a support assembly is also connected to the conveyor seat. The support assembly includes an L-shaped support bend positioned opposite to the conveyor seat. The L-shaped support bend is connected to the conveyor seat via a deflection motor. When the deflection motor drives the L-shaped support bend to the working position, the L-shaped support bend supports the floor decking. When the deflection motor drives the L-shaped support bend to the stop position, the L-shaped support bend disengages and releases the floor decking.

[0016] Furthermore, the L-shaped support bend can be constructed in various forms, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the L-shaped support bend structure includes a connecting rod that connects and cooperates with the deflection motor, and a support rod that cooperates with the connecting rod. The support rod is forked and forms at least two support ends. When the above scheme is adopted, the L-shaped support bend can serve as a load-bearing structure for lifting and transporting floor decking, helping to improve the stability of lifting floor decking.

[0017] The above discloses a mobile installation device, and the present invention also discloses a construction method.

[0018] A method for moving and installing steel structure floor decking, comprising: A mobile installation device is set on the steel structure beam to be constructed, so that the conveyor seat can travel along the conveyor track and convey the floor deck to the corresponding installation position; The conveyor belt moves the load-bearing frame to the floor decking pick-up area. The lifting components lift the floor decking at multiple points and move it smoothly away from the pick-up area. The conveyor belt moves the load-bearing frame to the installation point of the floor decking, and the lifting assembly places the floor decking into the installation point. Adjust the position of the floor decking so that both ends of the floor decking are aligned with the target steel beam and overlapped on the target steel beam; The floor decking is installed and fixed to the target steel beam; Repeat the above process until all the floor decking is installed.

[0019] Furthermore, when lifting a single floor deck slab at multiple points using lifting components, flexible lifting straps are used for the lifting components, and the number of lifting components is at least two.

[0020] Furthermore, during the lifting and lowering of the floor deck, the L-shaped support bend applies force to the lower surface of the floor deck and supports and lifts the floor deck.

[0021] Compared with the prior art, some of the beneficial effects of the technical solution disclosed in this invention include: 1. High safety: The truss floor slabs are moved sequentially by mobile hoisting equipment, which completely avoids workers moving heavy objects in unsupported areas at high altitudes, greatly reducing safety risks.

[0022] 2. Highly efficient construction: It enables mechanized assembly line operation for floor decking installation, with fast handling speed and installation efficiency far exceeding that of manual labor, significantly shortening the construction period.

[0023] 3. Low cost: The device can be modularly designed and reused, eliminating the need to lease expensive large machinery, resulting in low manufacturing and maintenance costs.

[0024] 4. High adaptability: Specifically designed to solve the specific working condition of "limited top space", it makes full use of the existing structure and cleverly combines the load-bearing and walking systems.

[0025] 5. Quality assurance: Multi-point hoisting and flexible hoisting tools effectively prevent deformation and damage to the floor decking during hoisting, ensuring installation quality.

[0026] 6. Flexible and controllable: The device is flexible in movement, has a wide coverage area, is easy to operate, and has high positioning accuracy. Attached Figure Description
