Description

Technical Field

[0001] The utility model relates to the technical field of high-rise building facade construction, in particular to a ring-rail adjustable hoisting device used for constructing high-rise building facade curtain walls. Background Art

[0002] When the main structure of a high-rise building is completed, due to the high building height, in order to solve the vertical and horizontal transportation and installation problems, it is necessary to use lifting equipment with ring rails to install the curtain wall. The general process is to use a certain floor slab of the middle and high floors of the building as the base layer, and fix a cantilever beam perpendicular to the edge of the floor slab at a certain distance on the base floor slab, so as to lay out a circle of multiple cantilever beams outside the base floor slab, and then fix an I-beam hanging rail perpendicular to the cantilever beam on each cantilever beam, and connect all the I-beam hanging rails end to end to form a ring hanging rail around the base floor slab, that is, a ring rail. The ring rail is divided into a straight section and an arc section. The arc section is located outside the corner of the floor slab and the straight section is parallel to the straight edge of the floor slab. The circular track is slidably matched with a trolley, which is equipped with a winch. The lower end of the winch traction rope is provided with a hoist for lifting glass panels, aluminum panels and other curtain wall panels; to ensure stability, it is also necessary to pre-embed multiple upper hanging ring components in the upper floor slab, and the above-mentioned upper hanging ring components correspond to the cantilever beams one by one. Each upper hanging ring component is reinforced with the outer end of the corresponding cantilever beam through a pull rod. At this point, the installation of the lifting equipment of the base layer is completed. Then, start to hoist the curtain wall panels layer by layer from bottom to top, that is, drive the trolley to travel along the circular track for one circle, and hoist all the curtain wall panels of the ath layer below the base layer, such as the 3rd layer, into place, and then drive the trolley to travel another circle to hoist all the curtain wall panels of the a+1th layer, such as the 4th layer, and repeat this cycle... until the next layer of curtain wall panels of the base layer is hoisted. If the 12th layer is used as the base layer, the curtain wall panels of the 11th layer will be hoisted.

[0003] For the sake of convenience, the floor where the curtain wall panels are being hoisted is called the hoisting floor.

[0004] If the building facade is completely vertical, it can be hoisted upwards layer by layer. However, if the building facade is not vertical, such as a tower structure with a small top and a large bottom, it is necessary to replace the cantilever beam according to the convexity of the facade of different floors to change the cantilever distance. That is, the cantilever distance is long when hoisting a relatively convex low floor, and the cantilever distance is short when hoisting a relatively concave high floor. This ensures that the hoisting point always maintains a suitable distance from the edge of the hoisting layer, so that workers standing on the edge of the floor can reach the curtain wall panel.

[0005] However, the existing hoisting equipment has the following defects. The existing cantilever beam is fixed to the foundation floor by multiple U-shaped buckles and anchor bolts. When the building facade is tilted and the cantilever beam needs to be replaced to adjust the cantilever distance, the anchoring length of the inner side of the beam is different due to the different total lengths of each beam, resulting in different anchoring points of the anchor bolts on the floor. Therefore, it is necessary to drill many anchor bolt holes on the foundation floor to meet the anchoring requirements of the inner side of beams of different lengths. This makes the replacement process of the cantilever beam cumbersome, time-consuming and labor-intensive, and too many holes in the floor also increase the workload of later repair and plugging. Moreover, since the ring rails are fixed on each cantilever beam, before replacing the cantilever beam, all the ring rails need to be disassembled into sections of I-beam hanging rails and all the I-beam hanging rails need to be removed from the corresponding cantilever beams. After the new cantilever beam is fixed, each section of the I-beam hanging rail needs to be fixed to the corresponding cantilever beam again, and each section of the I-beam hanging rail needs to be re-connected to the ring rail. The disassembly and assembly process is cumbersome and laborious. Disassembly requires cutting section by section, and assembly requires welding and grinding section by section. The workload is large and it is high-altitude operation, which is very inconvenient. There is also a safety hazard of falling from height or falling objects. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a curtain wall ring rail hoisting device for high-rise buildings, which can quickly and conveniently adjust the cantilever distance of each cantilever beam when hoisting floors with different concave and convex facades, and does not need to replace the anchoring points of the anchor bolts.

[0007] The technical solution of the utility model is to provide a curtain wall ring rail hoisting equipment for high-rise buildings, which includes a base floor slab, a cantilever beam perpendicular to the edge of the floor slab is installed at a certain distance on the base floor slab, each cantilever beam is fixed with an I-beam hanging rail perpendicular to the cantilever beam, and all the I-beam hanging rails are connected end to end to form a ring rail around the base floor slab; the ring rail is divided into a straight section and an arc section, which are respectively located outside the straight edge and the corner of the base floor slab; a trolley with a hoisting device is slidably matched on the ring rail; a plurality of upper hanging devices are pre-buried in the upper floor slab Ring assembly, the outer end of each cantilever beam is connected to the corresponding upper hanging ring assembly through a pull rod; an N-shaped guide sleeve is sleeved in the inner gap of each cantilever beam, each guide sleeve is provided with three pairs of ear plates in the front, middle and rear, and each ear plate is screwed to the foundation floor through the first anchor bolt; each guide sleeve is provided with a clamping plate at a certain interval along the length, each clamping plate is provided with a clamping hole for clamping the cantilever beam downward, and each clamping hole is provided with two left and right side protrusions; when the first anchor bolt is tightened, the left and right side protrusions press the lower flange plate of the corresponding cantilever beam.

[0008] Compared with the prior art, the curtain wall ring rail hoisting equipment used in the above high-rise buildings has the following advantages.

[0009] The bamboo structure of the guide sleeve plus multiple clamping plates can press the cantilever beam evenly and stably along the length direction. In particular, after tightening the first anchor bolt, the special-shaped clamping mouth with left and right side convex parts can just clamp the I-shaped section of the cantilever beam and press the lower flange plate of the cantilever beam, ensuring that the cantilever beam is firmly installed on the floor slab and the cantilever support is reliable; more importantly, loosening but not unscrewing the first anchor bolt can not only moderately relax the clamping plate but also keep the cantilever beam limited, so that the cantilever beam can be flexibly pulled and moved along the length of the guide sleeve, thereby easily and conveniently adjusting the cantilever distance of the cantilever beam; and during the cantilever distance adjustment process, the anchoring points of the front, middle and rear three groups of ear plates and the first anchor bolt remain unchanged. There is no need to re-drill holes at new points every time the cantilever distance is adjusted as in the prior art, and no new anchor bolts are added. Therefore, the adjustment process of each cantilever beam is quick and convenient, and the workload of repairing and sealing the anchor bolt holes in the floor slab in the later stage is also reduced.

[0010] Preferably, the lifting equipment also includes a group of n hydraulic cylinders, the cylinder bodies of which are fixed to the foundation floor slab, and the piston rods of which are docked one by one with the rear ends of n adjacent cantilever beams on the straight section of the ring rail; in this way, every n adjacent cantilever beams on the straight section of the ring rail are regarded as a batch and processed batch by batch; the hydraulic cylinders are docked one by one on the inner side of each batch of cantilever beams, the first anchor bolts of the guide sleeves of the batch of cantilever beams are loosened, and the connections between the corresponding straight sections and the other sections on both sides are removed, and then the batch of n cantilever beams and the n sections of I-beam hanging rails of the corresponding straight sections can be pulled as a whole at one time. The prior art is to split all the ring rails into a large number of single-section I-beam hanging rails, and remove each section of the I-beam hanging rail from the corresponding cantilever beam. After each cantilever beam is adjusted into place and fixed one by one, all the I-beam hanging rails are reinstalled back to the corresponding cantilever beams, and then the single-section I-beam hanging rails are re-welded into a ring rail. In comparison, the present application can avoid the processes of disassembling all the ring rails into single-section hanging rails, pulling the cantilever beams one by one and then re-fixing all the single-section hanging rails, and then welding and grinding all the single-section hanging rails from head to tail. Therefore, the present application significantly reduces the workload, significantly reduces the labor intensity of workers, saves time and effort, and doubles the work efficiency.

[0011] As a further preference, the top edge of each pallet is welded to the lower surface of the top plate of the guide sleeve, and the two side edges of each pallet are respectively welded to the inner surfaces of the two side plates of the guide sleeve; this structure is easy to prepare, and only the three sides of the pallet need to be welded to the guide sleeve, and the connection effect is firm and stable, and the welded bamboo-shaped structure has high overall strength and strong bearing capacity.

The n shown is a natural number greater than 3, and is generally selected from 5 to 10 according to the actual situation of the construction site. Of course, the number is 8 in this embodiment, that is, the 8 cantilever beams 2 adjacent to each other on the straight section are regarded as a batch and pulled uniformly by 8 hydraulic cylinders 11.

[0023] A base 16 is welded to the cylinder body 11.1 of each hydraulic cylinder 11, and the base 16 is fixed to the foundation floor 1 by a second anchor bolt 17. The connection structure between the inner end of each cantilever beam 2 and the piston rod 11.2 of the corresponding hydraulic cylinder 11 is preferably that an end plate 12 is welded to the inner end of each cantilever beam 2, and a butt nut 13 is welded to the end plate 12; a butt screw 14 is rotatably mounted at the front end of the piston rod 11.2 of each hydraulic cylinder 11, and the butt screw 14 and the piston rod 11.2 are limited in the axial direction, and the butt screw 14 is screwed with the corresponding butt nut 13.

[0024] like Figures 1 to 5 As shown, a method for constructing a curtain wall ring rail hoisting device for a high-rise building using the utility model comprises the following steps.

[0025] When the convex and concave surfaces of different floors of a building need to be adjusted and the cantilever distance of the cantilever beam 2 of the hoisting equipment needs to be adjusted, for example, if the foundation floor slab 1 is the 15th floor, when the curtain wall panels of the ath floor, such as the 8th floor, are hoisted, and it is necessary to hoist the curtain wall panels of the a+1th floor, such as the 9th floor, whose convex and concave surfaces are different, every n adjacent cantilever beams 2 on the straight section of the ring track are regarded as a batch and processed one by one; in this embodiment, n is selected from 8, that is, 8 cantilever beams 2 are a batch, which are uniformly processed by 8 hydraulic cylinders 11.

[0026] The piston rods 11.2 of all n hydraulic cylinders 11 are connected to the rear ends of the first batch of cantilever beams 2 one by one, and the cylinder bodies 11.1 of the group of hydraulic cylinders 11 are fixed to the foundation floor 1 through the second anchor bolts 17. The straight section composed of the n I-beam hanging rails 3 fixed by the first batch of n cantilever beams 2 is used as the first straight section, and the tie rods 6 between each cantilever beam 2 and the corresponding upper hanging ring assembly 5 of the first straight section are loosened, and the two ends of the first straight section are cut off from the other sections of the ring rail. Then, the first anchor bolts 9 of the first batch of n cantilever beams 2 are loosened but not unscrewed, and the first batch of n cantilever beams 2 and the n sections of I-beam hanging rails 3 of the first straight section are used as the first straight section unit, and the n hydraulic cylinders 11 are pulled into place as a whole, so that the cantilever distance of each cantilever beam 2 in this batch meets the requirements of the new floor hoisting. Then, the first anchor bolts 9 of the first batch of n cantilever beams 2 are re-tightened and the tie rods 6 between the n cantilever beams 2 in this batch and the corresponding upper hanging ring assembly 5 are re-installed.

[0027] The piston rods 11.2 of all the n hydraulic cylinders 11 are connected one by one to the rear ends of the second batch of n cantilever beams 2, and the cylinder bodies 11.1 of this group of hydraulic cylinders 11 are fixed to the foundation floor 1. The straight section corresponding to the second batch of n cantilever beams 2 is the second straight section, and the straight section corresponding to the xth batch of n cantilever beams 2 is the xth straight section... Loosen the tie rods 6 between each cantilever beam 2 of the second straight section and the corresponding upper hanging ring assembly 5, and cut the two ends of the second straight section from the other sections of the ring rail. Then loosen the first anchor bolts 9 of the second batch of n cantilever beams 2. The second batch of n cantilever beams 2 and the n sections of I-beam hanging rails 3 of the second straight section are used as the second straight section unit, and are pulled into place as a whole by the group of n hydraulic cylinders 11. Then re-tighten the first anchor bolts 9 of the second batch of cantilever beams 2 and re-install the tie rods 6 between the cantilever beams 2 of this batch and the corresponding upper hanging ring assembly 5.

[0028] This cycle is repeated until the remaining batches of cantilever beams 2 and the corresponding straight sections are pulled into place as a whole using the same steps and the first anchor bolts 9 and tie rods 6 of the batch are fixed.

[0029] Each straight section pulled into place is butted against other adjacent straight sections, that is, welded and fixed, and the welds are polished off to make them smooth, so as to facilitate the passage of the trolley 4.

[0030] Finally, according to the method of the prior art, the old arc segment is removed from the corresponding cantilever beam 2, and the cantilever beam 2 corresponding to each arc segment is pulled and adjusted so that its cantilever length meets the requirements, and then the new arc segment is fixed to the outer end of the adjusted cantilever beam 2, and the two ends of the newly replaced arc segment are welded and fixed to the other segments of the ring rail. The above arc segment does not adopt the overall pulling method because the cantilever distance is different, the contour and size of the arc segment are different, and it cannot be universal, and can only be completely dismantled and replaced.

[0031] Of course, compared with straight sections, arc sections are fewer in number and shorter in distance. Straight sections are the mainstream of the circular rail. Therefore, this application improves the adjustment process of the straight sections that occupy most of the circular rail, thereby greatly improving the overall hoisting process of the circular rail.
