Technical Field

[0001] This invention relates to the field of wharf engineering construction technology, specifically to a construction operation platform for cast-in-place crossbeams at wharves. Background Technology

[0002] When constructing the cast-in-place crossbeams at the wharf, the crossbeam base frame is built using timber, and the bottom formwork is fixed on the timber. Then, the steel cage is tied to the bottom formwork for casting and positioning. After that, the side formwork is fixed. During the construction process, the timber is lengthened and a small, simple platform is erected to provide operating space on both sides of the crossbeam.

[0003] In the existing construction of cast-in-place crossbeams at the wharf, a small, simple platform is directly erected on the bottom formwork, and then a safety net is laid between the platforms of adjacent crossbeams for safety protection. However, its safety protection is not high. If a person falls onto the safety net, it will be difficult for them to climb up. At the same time, the platform space is limited, and operation is easily restricted. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a construction operation platform for cast-in-place crossbeams at a wharf, comprising an operation platform body and crossbeam timber. The operation platform body is installed between the crossbeam timbers of two crossbeams. The operation platform body is provided with a second mounting frame and a first mounting frame, and steel mesh is fixed to the upper end of both the second and first mounting frames. Hinges are evenly spaced between the second and first mounting frames, allowing them to rotate relative to each other. A second supporting steel pipe and a first supporting steel pipe are evenly spaced at the lower end of the second and first mounting frames, respectively, with the positions of the first and second supporting steel pipes corresponding to each other. Both the first and second supporting steel pipes are parallel to the reinforcing channel steel. A strip-shaped limiting groove is symmetrically opened at one end of the second supporting steel pipe. The limiting groove is connected to a connecting rod through a through-hole movable connection. Fastening collars are also evenly fixed through the connecting rod. The fastening collars are welded and fixed to the connecting rod, and the fastening collars are located on both sides of the second supporting steel pipe.

[0006] Preferably, U-shaped reinforcing channel steels are welded evenly at intervals within the second mounting frame and the first mounting frame, and the reinforcing channel steels are supported below the steel mesh.

[0007] Preferably, a positioning plate is welded and fixed inside the reinforcing channel steel on one side of the second mounting frame, and an adjusting screw is movably inserted between the positioning plate and the second mounting frame.

[0008] Preferably, the adjusting screw is arranged parallel to the reinforcing channel steel, and a movable connecting plate is fixed through the adjusting screw by a threaded structure, and the movable connecting plate is engaged with the U-shaped structure of the reinforcing channel steel.

[0009] Preferably, a connecting rod is fixed to the lower end of the movable connecting plate by insertion, and the connecting rod is perpendicular to the adjusting screw.

[0010] Preferably, the lengths of the first and second supporting steel pipes are both less than the widths of the first and second mounting frames, and the first and second supporting steel pipes respectively form right-angle groove structures with the outer surfaces of the first and second mounting frames, and the right-angle groove structures are engaged with the crossbeam timber.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-7This invention provides a technical solution: a construction operation platform for cast-in-place crossbeams at a wharf, comprising an operation platform body 1 and crossbeam timber 11. The operation platform body 1 is installed between the crossbeam timber 11 of two crossbeams. The operation platform body 1 is provided with a second mounting frame 3 and a first mounting frame 7, and steel mesh 2 is fixed to the upper end of both the second mounting frame 3 and the first mounting frame 7. The steel mesh 2 is more reliable than a safety net structure, improving the safety of the operation platform body 1. U-shaped reinforcing channel steel 4 is welded evenly at intervals inside the second mounting frame 3 and the first mounting frame 7, and the reinforcing channel steel 4 is supported below the steel mesh 2. In this structure, after the second mounting frame 3 and the first mounting frame 7 are rotated and folded via hinges 12, the steel mesh 2 overlaps, effectively reducing the operating pressure. The space occupied by the main body 1 of the platform during transport is provided by steel mesh 2, which is fixed between the crossbeams 11, so that there is an integral operating platform body 1 between the two crossbeams, so that there is a large operating space during the construction of the crossbeams. The reinforcing channel steel 4 supports the steel mesh 2. The dimensions of the second mounting frame 3 and the first mounting frame 7 are fixed according to the dimensions of the construction crossbeam. A rectangular structure is formed by welding square steel pipes, and the rectangular structure is reinforced by reinforcing channel steel 4. Hinges 12 are evenly spaced between the second mounting frame 3 and the first mounting frame 7, so that the second mounting frame 3 and the first mounting frame 7 can rotate relative to each other. Positioning plates 14 are welded and fixed in the reinforcing channel steel 4 on one side of the second mounting frame 3. An adjusting screw 5 is movably inserted between the second mounting frame 3 and the second mounting frame 4. The positioning plate 14 of this structure positions the adjusting screw 5 and allows it to rotate. A nut can be welded to the outer end of the adjusting screw 5 on the second mounting frame 3. The adjusting screw 5 is parallel to the reinforcing channel steel 4, and a movable connecting plate 10 is threaded through and fixed to the adjusting screw 5. The movable connecting plate 10 is engaged with the U-shaped structure of the reinforcing channel steel 4. This structure allows the movable connecting plate 10 to move by rotating the adjusting screw 5. The reinforcing channel steel 4 is used to limit the movement of the movable connecting plate 10. A connecting rod 15 is inserted and fixed to the lower end of the movable connecting plate 10, and the connecting rod 15 is perpendicular to the adjusting screw 5. In this configuration, when the movable connecting plate 10 moves under the action of the adjusting screw 5, it can drive the connecting rod 15 to move synchronously. The lower ends of the second mounting frame 3 and the first mounting frame 7 are respectively fixed with a second supporting steel pipe 9 and a first supporting steel pipe 6 at even intervals, and the positions of the first supporting steel pipe 6 and the second supporting steel pipe 9 correspond to each other. Both the first supporting steel pipe 6 and the second supporting steel pipe 9 are arranged parallel to the reinforcing channel steel 4, and one end of the second supporting steel pipe 9 has a symmetrically formed strip-shaped limiting groove 13. This structure uses the first supporting steel pipe 6 and the second supporting steel pipe 9 for bottom support of the first mounting frame 7 and the second supporting steel pipe 9. The connected parts are fixed by welding, and the limiting groove 13 and the connecting rod 15 are connected by a through-hole movable connection.Furthermore, fastening collars 16 are evenly and fixedly inserted through the connecting rod 15. This structure allows the connecting rod 15 to move under the limitation of the limiting groove 13. The fastening collars 16 are welded and fixed to the connecting rod 15, and the fastening collars 16 are respectively located on both sides of the second supporting steel pipe 9. This structure allows the fastening collars 16 to limit the connection between the connecting rod 15 and the second supporting steel pipe 9. The lengths of the first supporting steel pipe 6 and the second supporting steel pipe 9 are both less than the widths of the first mounting frame 7 and the second mounting frame 3. The first supporting steel pipe 6 and the second supporting steel pipe 9 respectively form right-angle groove structures with the outer surfaces of the first mounting frame 7 and the second mounting frame 3, and the right-angle groove structures are engaged with the crossbeam 11. This structure allows the main body 1 of the operating platform to be connected to the first mounting frame 7 and the second mounting frame 3 respectively through the first supporting steel pipe 6 and the second supporting steel pipe 9. The right-angle groove structure formed by the outer surface of the second mounting frame 3 engages and positions relative to the crossbeam timber 11, facilitating the quick installation and positioning of the operating platform body 1. This also aids in the in-situ casting construction of the wharf crossbeam. Movable connecting steel pipes 8 are movably inserted into each of the second support steel pipes 9. One end of each movable connecting steel pipe 8 is welded and fixed to a connecting rod 15, and the other end is also inserted and connected to the first support steel pipe 6. This structure allows the connecting rod 15 to move the movable connecting steel pipe 8, enabling it to be inserted from the second support steel pipe 9 into the first support steel pipe 6, connecting the first and second support steel pipes 6 and ensuring a stable connection between the second mounting frame 3 and the first mounting frame 7. This ensures the operating platform body 1 is stably fixed between the crossbeam timber 11.

[0023] Working Principle: When using this dock cast-in-place beam construction operation platform, firstly, after the beam timber 11 is erected during the dock cast-in-place beam construction, the main body 1 of the operation platform is erected. The second installation frame 3 and the first installation frame 7 are connected by hinges 12 and rotated outwards, placing the steel mesh 2 on top. The reinforcing channel steel 4 supports and reinforces the steel mesh 2. Then, the adjusting screw 5 is rotated, causing the movable connecting plate 10 to move, which in turn moves the connecting rod 15. The positioning plate 14 and the second installation frame 3 position the adjusting screw 5. The limiting groove 13 is used to connect the connecting rods 15 between the movable connecting steel pipes 8, allowing the connecting rods 15 to pass through the limiting groove 13. 3. Perform movement limiting treatment. The fastening collar 16 limits the connection between the connecting rod 15 and the second support steel pipe 9. When the connecting rod 15 moves, it drives the movable connecting steel pipe 8 to move relative to the second support steel pipe 9, so that the movable connecting steel pipe 8 is inserted into the first support steel pipe 6, realizing the connection between the first support steel pipe 6 and the second support steel pipe 9, so that the second mounting frame 3 and the first mounting frame 7 form a whole. At this time, the unfolding and fixing of the main body 1 of the operating platform is completed. Then, the main body 1 of the operating platform is moved between the crossbeams 11, and the right angle groove structure formed by the first support steel pipe 6 and the second support steel pipe 9 with the outer side of the first mounting frame 7 and the second mounting frame 3 respectively engages with the crossbeams 11 to realize the positioning of the main body 1 of the operating platform, thereby completing a series of tasks.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
