Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a docking construction operation platform which can slide and adapt to various steel sections and changes in section height and width. Background Art

[0002] The existing hoisting cages, typically made of rebar or angle iron, or operating platforms fixed to the lower flange of steel beams, cannot adapt to changes in the height, width, or flange thickness of steel beams. Changes in the height, width, or flange thickness of steel beams require the hoisting cage and operating platform to be remade or modified. Even when the steel beam has a box-shaped cross-section, the operating platform fixed to the lower flange of the beam cannot be used. Therefore, the existing technology has poor adaptability, requiring frequent production or modification of the hoisting cage and operating platform, which greatly limits the scope of use of the existing hoisting cage or operating platform.

[0003] The joints at both ends of an existing steel beam need to be constructed. When using the above-mentioned hoisting cage or operating platform, two can only be used at the same time, or one end must be constructed and then disassembled and installed at the other end. The production or disassembly and installation of the hoisting cage is time-consuming and labor-intensive, especially for some hoisting cages and operating platforms with large deadweights. Disassembly often requires the use of other important and tight construction resources such as tower cranes, which greatly increases construction costs. Therefore, the currently commonly used hoisting cages and operating platforms have poor applicability and require the production of multiple hoisting cages or operating platforms when installing a steel beam, resulting in increased construction costs. Or secondary transportation, which occupies other tight construction resources, thereby affecting construction progress and greatly increasing construction costs.

[0004] Therefore, it is a problem worthy of study to provide a sliding docking construction operation platform that can be reused for a long time, is simple to manufacture, assemble, and adjust, saves construction costs in the long term, and avoids occupying other important construction resources. It can adapt to various steel sections and changes in section height and width. Summary of the Invention

The present invention can slide relative to a variety of steel sections to meet different construction needs, and is applicable to a variety of steel beams with different cross-sections and steel beams with different cross-section heights and widths.

[0037] like Figure 9 and Figure 10 As shown, two horizontal support mechanisms 1 are provided, spaced apart and parallel to each other along the length of the steel section. The horizontal support mechanisms 1 include a transverse keel 101, a plurality of adjustment nuts 102 located on the upper surface of the transverse keel 101 and arranged along its length, a first roller assembly fixedly connected to the lower surface of the transverse keel 101, and a keel connecting rod 103 fixedly connected to two adjacent transverse keels 101 at both ends.

When the horizontal support mechanism 1 needs to be moved, the first pulley 106 moves on the surface of the steel section to reduce the friction between the horizontal support mechanism 1 and the steel section.

[0039] The keel connecting rod 103 is made of 40mm*40mm square steel, and the transverse keel 101 is made of 80mm*40mm square steel, forming a 120° angle in the middle. Several adjustment nuts 102 are M20 nuts, symmetrically and evenly arranged along the length direction from the center of the transverse keel 101 to both ends, so that the adjustment nuts 102 on both sides of the transverse keel 101 are always at the same elevation. The single first retractable pulley screw 104 consists of an M22 sleeve with an upper section covered with reverse thread and a lower section covered with normal thread, and an M20 screw rod covered with normal thread and reverse thread respectively. The two screw rods are located at both ends of the sleeve. A first adjustment handle 105 is welded to the sleeve, so that the length of the screw rod can be adjusted by adjusting the first adjustment handle 105. The single first pulley 106 is a pulley with an outer diameter of 50mm and a first pulley lock 107. The lifting lug 108 is made of 10 thick iron plates.

[0040] like Figure 11 and Figure 12 As shown, four vertical support mechanisms 2 are provided, and the four vertical support mechanisms 2 are symmetrically distributed and respectively located on the left and right sides of the steel section. The vertical support mechanism 2 includes a vertical pole keel 201 connected to the horizontal support mechanism 1 at the top and located in the vertical direction, a first sliding assembly located on the side of the vertical pole keel 201, a first connecting bolt assembly 205 located at the top of the vertical pole keel 201, and a connecting hole 206 located at the lower part of the vertical pole keel 201. The first sliding assembly is connected to the horizontal reinforcement mechanism 4 to adjust the position of the horizontal reinforcement mechanism 4.

[0041] The first sliding assembly includes a first U-shaped rail 202 located on the side of the vertical keel 201, a first sliding pad 203 that cooperates with the first U-shaped rail 202, and a first sliding nut 204 located on the first sliding pad 203. The first sliding nut 204 moves along the length of the first U-shaped rail 202. The length of the first U-shaped rail 202 is the same as the length of the vertical keel 201. The first sliding nut 204 is connected to the horizontal reinforcement mechanism 4. The first connecting bolt assembly 205 is connected to the adjusting nut 102 to secure the vertical keel 201 to the transverse keel 101. The first sliding nut 204 is connected to the horizontal reinforcement mechanism 4 to secure the horizontal reinforcement mechanism 4.

[0042] The vertical pole keel 201 is made of 80mm*40nmm square steel, and the upper end is made of 20mm thick iron plate into a special-shaped connecting head, and a bolt hole with a diameter of 20mm is opened on the special-shaped connecting head. It is connected to the horizontal support mechanism 1 through the first connecting bolt assembly 205. The first connecting bolt assembly 205 includes an M20 nut, a screw rod matching the M20 nut, and two 3mm gaskets. The first U-shaped slide rail 202 is made of 60mm*20mm square steel, and one side of the slot is made into a "U" shape. The first sliding pad 203 is made of 10mm thick iron plate and is connected to the first U-shaped slide rail 202 through four screw rods with a diameter of 5mm. The first sliding nut 204 of M20 is welded on the first sliding pad 203. Thereby, the first sliding nut 204 can slide along the first U-shaped slide rail 202. Baffles 207 are located at both ends of the first U-shaped slide rail 202 and are made of PL75 angle steel to prevent the first sliding pad 203 and the first sliding nut 204 from sliding out of the first U-shaped slide rail 202. The connecting holes 206 are circular holes with a diameter of 20 mm and are set at intervals of 100 mm.

[0043] like Figure 13 and Figure 14 As shown, four vertical sliding mechanisms 3 are provided, and the four vertical sliding mechanisms 3 are symmetrically distributed and respectively located on the left and right sides of the steel section. The vertical sliding mechanism 3 includes a sliding keel 301 located in the vertical direction, a plurality of second roller assemblies located in the length direction of the sliding keel 301, a second connecting bolt assembly 308 located at the top of the sliding keel 301, a plurality of tension screw connection holes 302 located at the lower part of the sliding keel 301, and a tension screw 307 located at the lower part of the sliding keel 301, the two ends of which are respectively connected to the adjacent sliding keels 301, and the tension screw 307 is threadedly connected to the tension screw 307 connection hole.

[0044] The second roller assembly includes a second retractable pulley screw 303 whose end is fixedly connected to the side of the sliding keel 301, a second adjustment handle 304 located on the second retractable pulley screw 303 and used to adjust the length of the second retractable pulley screw 303, a second pulley 305 connected to the second retractable pulley screw 303, and a second pulley lock 306 located on the second pulley 305. When the vertical support mechanism 2 and the horizontal support mechanism 1 need to be moved, the second pulley 305 moves on the surface of the steel section to reduce the friction between the vertical support mechanism 2 and the horizontal support mechanism 1 and the steel section, and the vertical support mechanism 2 does not contact the surface of the steel section.

[0045] The second connecting bolt assembly 308 includes an M20 nut, a screw that matches the M20 nut, and two 3mm washers. The tension screw connection hole 302 is located at the lower end of the sliding keel 301 and has a diameter of 20mm. It is arranged at 50mm intervals. The second retractable pulley screw 303 consists of an M22 sleeve with an upper section covered with reverse thread and a lower section covered with normal thread, and an M20 screw that is covered with normal thread and reverse thread, respectively. The two screws are located at either end of the sleeve. A second adjustment handle 304 is welded to the sleeve, and the length of the screw can be adjusted by adjusting the second adjustment handle 304. The second pulley 305 uses a pulley with an outer diameter of 50mm and a second pulley lock 306. The second pulley lock 306 is used to adjust whether the pulley can slide. The tension screw 307 consists of two M20 nuts, a screw that matches the M20 nut, and two 3mm washers. The two sliding keels 301 on both sides of the steel beam are connected through the tension screw connection hole 302. The two vertical sliding mechanisms 3 are effectively connected together to stably bear the force.

[0046] like Figure 15 and Figure 16 As shown, the horizontal reinforcement mechanism 4 includes a reinforcement keel 401 located in the horizontal direction, a second sliding assembly located on the reinforcement keel 401, and the second sliding assembly is connected to the horizontal support mechanism 1 to increase firmness. The second sliding assembly includes a second U-shaped slide rail 402 located on the side of the reinforcement keel 401, a second sliding pad 403 matched with the second U-shaped slide rail 402, a second sliding nut 404 fixedly connected to the second sliding pad 403, and a third connecting bolt assembly 405 matched with the second sliding nut 404.

[0047] The reinforcement keel 401 is made of three 60mm wide and 10mm thick iron plates welded into a channel steel shape. The second U-shaped slide rail 402 is made of 60mm*20mm square steel, and one side of the slot is made into a "U" shape. The second sliding pad 403 is made of 10mm thick iron plate and is connected to the second U-shaped slide rail 402 through four screw rods with a diameter of 5mm. The second sliding nut 404 of M20 is welded on the second sliding pad 403. Thereby, the second sliding nut 404 can slide along the second U-shaped slide rail 402. Four groups of such second sliding pads 403 and second sliding nuts 404 are set on the reinforcement keel 401. The adjustment nut 102 in the horizontal support mechanism 1 and the first sliding nut 204 in the vertical support mechanism 2 are respectively connected by the third connecting bolt assembly 405. The baffles 406 are located at both ends of the second U-shaped rail 402 and are made of PL75 angle steel to prevent the second sliding pad 403 and the second sliding nut 404 from sliding out of the second U-shaped rail 402. The third connecting bolt assembly 405 includes an M20 nut, a screw rod matching the M20 nut, and two 3mm washers.

[0048] like Figure 17 and Figure 18 As shown, the operating platform mechanism 5 includes a platform main keel 501, a platform secondary keel 502 connected to the platform main keel 501, a plurality of operating platform connection holes 503 located on the platform main keel 501, and a fourth connection bolt assembly 504 matching the operating platform connection holes 503.

[0049] There are two operating platform mechanisms 5. The main platform keels 501 use 60mm*40mm square steel to form the main cage frame. The secondary platform keel 502 is made of round steel with a diameter of 20mm. Together with the main platform keel 501, it forms a stepping platform for construction workers. An operating platform connection hole 503 with a diameter of 20mm is opened at the upper end of the main platform keel 501, and one is set at an interval of 100mm. It can always correspond one-to-one with the connection hole 206 in the vertical support mechanism 2. Then use the fourth connecting bolt assembly 504 to connect with the connection hole 206 in the vertical support mechanism 2 through the operating platform connection hole 503. The fourth connecting bolt assembly 504 includes an M20 nut, a screw rod matching the M20 nut, and two 3mm gaskets. In order to keep the operating platform mechanism 5 stable and stressed, multiple fourth connecting bolt assemblies 504 can be set.

[0050] The working process and working principle are as follows: The present invention is applicable to various steel sections, such as Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 As shown, they are used when the box section beam 6 and H section beam 7 are working and sliding. Figure 5 、 Figure 6When the box-section beam 6 is in use, the horizontal support mechanism 1 is positioned above the box-section beam 6 via four first pulleys 106. Depending on the width of the box-section beam 6, the upper end of the vertical support mechanism is connected to corresponding adjustment nuts 102, ensuring a total clearance of approximately 10 mm between the vertical support mechanism 2 and both sides of the box-section beam 6. This 10 mm clearance ensures the safety of the entire operating platform while allowing the vertical support mechanism 2 to be installed with a certain tolerance on both sides of the box-section beam 6. The operating platform mechanism 5 is then connected to the horizontal support mechanism 1 via multiple operating platform connection holes 503. Depending on the height of the box-section beam 6, the entire operating platform can be adjusted to the desired height in two ways: The first method involves adjusting the height of the first retractable pulley screw 104 by adjusting the first adjustment handle 105 in the horizontal support mechanism 1, while the second method involves adjusting the height using the multiple connection holes 206 below the vertical support mechanism 2. Both methods can also be used in combination until the entire operating platform is adjusted to the desired height of the box-section beam 6. Depending on the width of the box-section beam 6, the upper end of the vertical sliding mechanism 3 is connected to the corresponding adjustment nut 102. The second retractable pulley screw 303 is adjusted using the second adjustment handle 304 so that the second pulley 305 is in close contact with the side of the box-section beam 6. The tension screw 307 is then tightened through the tension screw connection hole 302 at the lower end of the vertical sliding mechanism 3. The horizontal reinforcement mechanism 4 is then placed above the box-section beam 6. The four second sliding nuts 404 are adjusted along the second U-shaped guide rail 402 so that they are always connected to the corresponding two adjustment nuts 102 in the horizontal support mechanism 1 and the second sliding nuts 404 in the vertical support mechanism 2. The first pulley lock 107 and the second pulley lock 306 are then adjusted to lock all pulleys, preventing them from sliding. Two stable load-bearing systems are now formed: the first is a triangular stable load-bearing system formed by the horizontal support mechanism 1, the vertical support mechanism 2, and the upper end of the horizontal reinforcement mechanism 4. When the entire operating platform is in operation, the two force-bearing systems are stable and jointly bear the force, ensuring the safety of the entire structure. When the construction opening of the box-section beam 6 at this end is completed and it needs to be slid to the other end of the box-section beam 6 for construction, the four second sliding nuts 404 in the horizontal reinforcement mechanism 4 are loosened and the horizontal reinforcement mechanism 4 is removed. In other words, assuming that the second force-bearing system is no longer under force, the first force-bearing system formed by the horizontal support mechanism 1 and the vertical support mechanism 2 can still ensure that the entire operating platform will not overturn or collapse. Then, loosen the first pulley lock 107, and the entire operating platform can now be moved as a whole via the 12 pulleys that are tightly attached to the box-section beam 6. The entire operating platform can then be easily pushed and pulled to the construction opening at the other end of the box-section beam 6 using the lifting lugs 108. After reaching the construction opening at the other end of the box-section beam 66, the horizontal reinforcement mechanism 4 is installed using the four second sliding nuts 404 in the first pulley lock 107.At this point, the first and second sets of load-bearing systems are stable and bear the load together, and the construction workers can continue to construct the 6th joint of the box-section beam at this end. Figure 7 、 Figure 8 The H-section beam 7 is used in the same manner and in the same principles as the box-section beam 6. The only difference is that the second retractable pulley screw 303 is adjusted using the second adjustment handle 304 in the vertical sliding mechanism 3 so that the second pulley 305 is in close contact with the web of the H-section beam 7. The sliding procedure and principles are the same as those for the box-section beam 6.
