Description

Technical Field

[0001] The invention relates to the technical field of high-rise building facade construction, in particular to a rotating shaft type curtain wall ring rail hoisting device and a construction method for constructing the facade of a high-rise building. Background Art

[0002] When the main structure of a high-rise building is completed, a lifting device with a ring rail is required to install the curtain wall. The general process is as follows: take a certain floor slab of the middle and high-rise buildings as the foundation layer, arrange a circle of multiple cantilever beams at intervals along the edge of the foundation layer slab, each cantilever beam is perpendicular to the edge of the slab, and each cantilever beam is anchored to the foundation layer slab through several U-shaped buckles and ground anchor bolts; then, embed multiple upper hanging ring assemblies corresponding to the cantilever beams in the upper floor slab of the foundation layer, and reinforce each upper hanging ring assembly and the outer end of the corresponding cantilever beam through a pull rod, so as to form a supporting system with anchoring as the main and oblique pulling as the auxiliary; 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 circular hanging rail, i.e., a ring rail, which goes around the foundation layer slab; then, slide a trolley on the ring rail, the trolley is equipped with a winch, and the lower end of the hoisting rope of the winch is provided with a hoisting device for hoisting glass panels, aluminum panels and other curtain wall panels. After the installation of the above hoisting equipment is completed, the curtain wall panels are hoisted layer by layer from bottom to top, that is, the trolley is driven to travel along the circular track for one circle to hoist all the curtain wall panels of the ath layer below the foundation layer into place, and then the trolley is driven to travel another circle to hoist all the curtain wall panels of the a+1th layer, and this cycle continues...

[0003] It is common sense that the circular track is divided into straight sections and curved sections. The straight sections are parallel to the normal straight sides of the floor slabs, while the curved sections are located at the corners of the floor slabs. The straight sections occupy most of the length of the circular track. The technical solutions involved in this application are all improvements on the straight sections, while the curved sections are still constructed using the existing methods.

[0004] There is a defect in the ring rail hoisting equipment and construction method of the prior art, that is, the amount of high-altitude work during the installation and disassembly process of the hoisting equipment is large. Specifically, from the time the cantilever beam is anchored and diagonally pulled, the subsequent installation steps of screwing the corresponding I-beam hanging rail on each cantilever beam, spot welding each I-beam hanging rail section by section, and polishing each welding point of the ring rail are all high-altitude operations; and during disassembly, the steps of gas cutting the complete ring rail into single I-beam hanging rails and removing each I-beam hanging rail and the corresponding cantilever beam also all require high-altitude operations; too much high-altitude work makes the construction time-consuming and labor-intensive, and also poses a safety hazard. Summary of the invention

[0005] A technical problem to be solved by the present invention is to provide a rotary shaft curtain wall ring track hoisting device which can significantly reduce the amount of high-altitude work and make the assembly and disassembly process more convenient, faster and safer.

[0006] A technical solution of the present invention is to provide a rotating shaft curtain wall ring rail hoisting equipment, which includes a base floor slab, a circle of multiple cantilever beams are arranged at intervals along the edge of the base floor slab, and a circle of multiple upper hanging ring assemblies are pre-buried in the upper floor slab, and the lower hanging ear of the hanging end of each cantilever beam is connected to the upper hanging ear of the corresponding upper hanging ring assembly through a pull rod; each cantilever beam is connected to a vertical I-beam hanging rail, and all the I-beam hanging rails are connected end to end to form a circle of ring rails; the ring rails are slidably matched with a trolley with a hoisting device; the base The base floor is fixed with multiple axle seats, and a rotating shaft is fixed to the non-suspension end of each cantilever beam via an ear plate, and the rotating shaft of each cantilever beam fits in the corresponding axle seat; a lifting ring is also provided at the suspension end of each cantilever beam, and multiple main fixed pulleys and multiple winches are installed on the upper floor. The lifting ring of each cantilever beam is connected to the corresponding winch of the upper floor through a traction rope passing around the main fixed pulley corresponding to the upper floor; an auxiliary U-shaped buckle is provided on the beam section of each cantilever beam close to the edge of the floor, and the auxiliary U-shaped buckle is anchored to the base floor.

[0007] Another technical problem to be solved by the present invention is to provide a construction method based on a rotating shaft curtain wall ring rail hoisting device with less high-altitude work and more convenient, faster and safer assembly and disassembly processes.

[0008] A technical solution of the present invention is to provide a construction method based on a rotating shaft curtain wall ring track hoisting device, which includes the following steps.

[0009] The installation process of the device includes:

[0010] A circle of multiple axle seats are fixed on the floor slab of the foundation layer, the hanging end of each cantilever beam is facing inwards and the hanging ring is at the bottom, and the rotating shaft of each inverted cantilever beam is installed in the corresponding axle seat;

[0011] Fix the corresponding winch, main fixed pulley and upper hanging ring assembly on the upper floor slab; pass each winch traction rope around the corresponding main fixed pulley, then pass around the corresponding hanging end of the overturned cantilever beam on the base floor slab and hook it with the corresponding hanging ring;

[0012] Taking n adjacent cantilever beams as a group, installing n I-beam hanging rails of the group of n cantilever beams on the floor slab of the foundation layer, and spot welding the group of n I-beam hanging rails to form a continuous ring rail segment, and polishing the welding points of the ring rail segment smooth;

[0013] Synchronously drive the n winches corresponding to the ring track segment, and pull the corresponding n cantilever beams outward through the n traction ropes until the ring track segment is turned outward as a whole out of the floor edge;

[0014] The auxiliary U-shaped buckles of the n cantilever beams after being turned outward are anchored to the base floor slab; and the lower hanging ears of the n cantilever beams after being turned outward are obliquely fixed to the upper hanging ears of the n upper hanging ring assemblies corresponding to the upper floor slab by n tie rods;

[0015] Repeat the above steps, hinge the next group of n inverted cantilever beams on the base floor, fix the next group of n I-beam hanging rails, weld and grind them into the next ring rail segment; then pull the next ring rail segment outward as a whole, anchor it and pull it diagonally;

[0016] Using high-altitude operations, spot weld each ring rail after turning it inside out, and grind the welding points to form a complete ring rail.

[0017] The disassembly process of the equipment includes: using high-altitude operations to disassemble the complete ring track into multiple ring track segments;

[0018] Remove the n tie rods and n auxiliary U-shaped buckles of a ring track segment, then drive the n winches corresponding to the ring track segment to pull the corresponding n cantilever beams to swing inwards until the ring track segment is turned inwards as a whole onto the foundation floor slab;

[0019] Standing on the foundation floor, the inverted ring rail is segmented into n I-beam hanging rails and the n I-beam hanging rails are removed from the corresponding cantilever beams;

[0020] Use the same steps to remove the next track segment.

[0021] Compared with the prior art, the above-mentioned rotary shaft curtain wall ring rail hoisting equipment and construction method have the following advantages.

[0022] This solution changes the original support system that was mainly anchored and supplemented by diagonal tension to a form that is mainly diagonal tension and supplemented by anchoring. In this way, each I-beam hanging rail can be screwed in the floor slab and welded and polished, thereby significantly reducing the workload of high-altitude operations; taking n as 4 as an example, it was originally necessary to screw 4 I-beam hanging rails to the corresponding cantilever beams in the air, and weld and polish 5 welds, but now they can be spliced, spot welded, and polished into ring rail segments in the floor slab and then turned outward as a whole. In this way, only two welds of the ring rail segments need to be spot welded and polished in the air. The high-altitude operation part of the disassembly process also only requires the process of cutting the ring rail into ring rail segments, and the subsequent further cutting of the ring rail segments is completely completed by workers on the floor slab after turning inward. In summary, this application significantly reduces the amount of high-altitude operations, making the operation faster, more efficient and safer. Moreover, the process of hinged one end of the cantilever beam and towing the other end with a winch in this application provides stable guidance for the cantilever beam and the ring rail segment, so it is also more labor-saving and safer.

[0023] The upper suspension ring assembly is preferably composed of a bottom steel plate. The four corners of the bottom steel plate are anchored to the upper floor slab through ground anchor bolts. A steel I-beam column is welded to the bottom steel plate, and an upper suspension ear is welded to the middle section of the front flange plate of the column. At the top of the column, a channel steel top beam with an upward notch is welded. The web of the channel steel top beam is welded to the top of the column, and triangular reinforcing ribs are welded between them. A corresponding main fixed pulley is rotatably installed between the two flange plates of the channel steel top beam. The main fixed pulley is located at the outer end of the channel steel top beam. This preferred structure integrates the main fixed pulley and the upper suspension ear on the same bracket, which avoids the problem of removing the main fixed pulley bracket and then installing the upper suspension ear bracket after the cantilever beam is turned outwards, and also avoids the problem of removing the upper suspension ear and replacing the main fixed pulley before inverting inwards. After the structure is anchored to the floor slab at one time, there is no need to switch back and forth and install repeatedly. Moreover, the upper suspension ear and the main fixed pulley are arranged staggeredly, ensuring that the traction rope and the pull rod are basically flush and staggered from each other, and their functions do not interfere with each other, which is convenient for installing the pull rod without loosening the traction rope after the cantilever beam is turned in place, achieving double insurance. Furthermore, the main body of the above-mentioned bracket structure is welded by two vertical and horizontal steel profiles, with a simple structure but reliable strength, and can stably bear the load of tension traction.

[0024] As a further preference for the upper suspension ring assembly, it further includes a U-shaped rubber pad. The U-shaped rubber pad is clamped on the edge of the upper floor slab. The upper plate of the U-shaped rubber pad overlaps the outside of the bottom steel plate and is locked by the ground anchor bolts at the two outer corners of the bottom steel plate. In this way, the rubber pad is convenient to install. Instead of additionally driving ground anchor bolts, the existing two outer corner ground anchor bolts of the bottom steel plate are utilized, serving two purposes. And the rubber pad is clamped to the floor slab and combined with the bolt connection method, so it is installed firmly and does not fall off. Moreover, it effectively covers the sharp edges of the floor slab edge, protects the traction rope, and reduces wear.

[0025] Preferably, arc-shaped notches are provided at the cantilever ends of the upper and lower flange plates of the cantilever beam. In this way, for the cantilever beam in the initial inverted state, its suspension ring faces downward, and the traction rope connected to the suspension ring needs to bypass the suspension end of the cantilever beam to extend upward and connect to the upper winch. The arc-shaped notches effectively protect the traction rope from being scratched by the sharp edges of the flange plate edge at the cantilever end, and center the traction rope, making the traction rope not tilt left and right, ensuring smooth and powerful traction tension.

[0026] As a further preference, a steel end plate is welded to the non-suspension end of the cantilever beam, an ear plate is vertically welded to the steel end plate, the non-welded end of the ear plate is an arc part, and a rotating shaft is welded to the center of the arc part. In this way, the ear plate is welded firmly and stably with good strength to ensure a firm and smooth hinged turning process, and the arc part at the end of the ear plate makes the turning smoother.

Specific embodiments

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] As Figures 1 to 7 Shown, the rotating shaft type curtain wall ring rail hoisting equipment of the present invention includes a basic floor slab 1, and a plurality of cantilever beams 2 are arranged at intervals along the edge of the basic floor slab 1 in a circle. Each cantilever beam 2 is perpendicular to the edge of the basic floor slab 1. More precisely, the cantilever beam 2 is normal to the edge of the basic floor slab 1.

[0037] One floor slab above the base layer, i.e., the upper floor slab 3, is pre-embedded with a circle of multiple upper hanging ring assemblies. Each suspension end of each cantilever beam 2 is provided with a lower lifting lug 4. The lower lifting lug 4 of each cantilever beam 2 is connected to the upper lifting lug 6 of the corresponding upper hanging ring assembly through a tie rod 5. The upper hanging ring assembly includes a bottom steel plate 7. The four corners of the bottom steel plate 7 are anchored to the upper floor slab 3 through four ground anchor bolts. A steel column 8 is welded to the bottom steel plate 7. The upper lifting lug 6 is welded in the middle of the front flange plate of the column. A channel steel top beam 9 with an upward notch is welded to the top of the column. The web of the channel steel top beam 9 is welded to the top of the column and triangular reinforcing ribs are welded between the two. A corresponding main fixed pulley 10 and an auxiliary fixed pulley 11 are rotatably installed between the two flange plates of the channel steel top beam 9. The main fixed pulley 10 is located at the outer end of the channel steel top beam 9, and the auxiliary fixed pulley 11 is located at the inner end of the channel steel top beam 9.

[0038] Each cantilever beam 2 is connected to an I-beam hanging rail 12.1 perpendicular to the cantilever beam 2. All the I-beam hanging rails 12.1 are connected end to end to form a loop rail around the base floor slab 1. A trolley 13 with a lifting device is slidably fitted to the loop rail.

[0039] The base floor slab 1 is fixed with multiple shaft seats 14 through ground anchor bolts. The non-suspension end of each cantilever beam 2 is fixed with a rotating shaft 16 through an ear plate 15. That is, a steel end plate is welded to the non-suspension end of the cantilever beam 2, the ear plate 15 is perpendicularly welded to the steel end plate, the non-welded end of the ear plate 15 is an arc part, and the rotating shaft 16 is welded at the center of the arc part. The rotating shaft 16 of each cantilever beam 2 is rotatably fitted in the corresponding shaft seat 14.

[0040] Each suspension end of each cantilever beam 2 is also provided with a lifting ring 17. Multiple winches 18 are installed on the upper floor slab 3. The chassis of the winch 18 is also anchored to the upper floor slab 3 through anchor bolts. In this embodiment, each winch 18 corresponds to a traction rope 19, an auxiliary fixed pulley 11, a main fixed pulley 10, and a cantilever beam 2. That is to say, the lifting ring 17 of each cantilever beam 2 is connected to the corresponding winch 18 on the upper floor slab 3 through a traction rope 19 passing around the corresponding main fixed pulley 10 and auxiliary fixed pulley 11 on the upper floor slab 3. An auxiliary U-shaped buckle 20 is also provided on the beam section of each cantilever beam 2 close to the floor edge. The auxiliary U-shaped buckle 20 is anchored to the base floor slab 1 through ground anchor bolts.

[0041] Each upper hanging ring assembly also includes a C-shaped rubber pad 21. The C-shaped rubber pad 21 is clamped on the edge of the upper floor slab 3. The upper plate of the C-shaped rubber pad 21 overlaps the outside of the bottom steel plate 7 of the same group of upper hanging ring assemblies and is locked by two ground anchor bolts at the two outer corners of the bottom steel plate 7.

[0042] Arc-shaped notches 22 are provided at the suspension ends of the upper and lower flange plates of each cantilever beam 2.

[0043] As Figures 1 to 7As shown, a construction method of the rotary shaft curtain wall ring track hoisting equipment according to the present invention includes the installation, use and disassembly of the hoisting equipment.

[0044] The installation process of this device includes the following steps.

[0045] A circle of multiple axle seats 14 are fixed on the foundation floor 1, and the hanging end of each cantilever beam 2 is facing inward and the hanging ring 17 is located at the bottom to make the cantilever beam 2 in an overturned state, and the rotating shaft 16 of each overturned cantilever beam 2 is rotatably installed in the corresponding axle seat 14.

[0046] The corresponding winch 18, main fixed pulley 10, auxiliary fixed pulley 11 and upper hanging ring assembly are fixed on the upper floor 3; the traction rope 19 of each winch 18 is passed around the corresponding auxiliary fixed pulley 11 and main fixed pulley 10, and then passed around the corresponding hanging end of the inverted cantilever beam 2 on the base floor 1 and hooked with the corresponding hanging ring 17.

[0047] Take n adjacent cantilever beams 2 as a group, and install n I-beam hanging rails 12.1 of the group of n cantilever beams 2 standing on the foundation floor 1, that is, screw the corresponding I-beam hanging rail 12.1 on each cantilever beam 2 of the group, and spot weld the n I-beam hanging rails 12.1 of the group one by one to form a continuous ring rail segment 12, and grind each welding point of the ring rail segment 12 to make it smooth and flat, so as to facilitate the passage of the trolley 13.

[0048] The n winches 18 corresponding to the ring track segment 12 are synchronously driven, and the n cantilever beams 2 corresponding to the ring track segment 12 are pulled outward by the n traction ropes 19 until the ring track segment 12 is turned outward from the edge of the floor slab. In this step, the workers slightly lift the suspension end to make the cantilever beam 2 rise to an angle for easy pulling and winding. Each winch 18 winds up the wire and pulls the cantilever beam 2 outward until each cantilever beam 2 and the traction rope 19 are straightened. Figure 2 After that, each winch 18 releases the wire, and the cantilever beam 2 continues to automatically turn outward under the action of its own weight until it is horizontal.

[0049] The auxiliary U-shaped buckles 20 of the group of n cantilever beams 2 after being turned outward are anchored to the base floor 1; and the lower hanging ears 4 of the n cantilever beams 2 after being turned outward are obliquely fixed to the upper hanging ears 6 of the n upper hanging ring assemblies corresponding to the upper floor 3 by n tie rods 5.

[0050] Repeat the above steps, hinge the next group of n inverted cantilever beams 2 on the foundation floor 1, fix the next group of n I-beam hanging rails 12.1, and weld and grind the n I-beam hanging rails 12.1 into the next ring rail segment 12; then pull the next ring rail segment 12 to turn outward as a whole, and then anchor and diagonally pull it.

[0051] By using high-altitude work, the turned-out ring rail segments 12 are spot-welded one by one, and the welding points are polished to form a complete ring rail.

[0052] Then a trolley 13 is slidably matched on the ring rail, and a hoisting winch is installed in the trolley 13. The lower end of the hoisting rope of the hoisting winch is provided with a hoisting device for hoisting the curtain wall panel.

[0053] After the installation of the above hoisting equipment is completed, the curtain wall panels are hoisted layer by layer from bottom to top, that is, the trolley 13 is driven to travel one circle along the circular track to hoist all the curtain wall panels of the ath layer below the foundation layer into place, and then the trolley 13 is driven to travel another circle to hoist all the curtain wall panels of the a+1th layer, and this cycle is repeated...

[0054] The disassembly process of the lifting equipment includes the following steps.

[0055] By using aerial work, the complete circular track is gas-cut and split into multiple circular track segments 12.

[0056] Remove the n tie rods 5 and n auxiliary U-shaped buckles 20 of a ring track segment 12, and then drive the n winches 18 corresponding to the ring track segment 12 to pull the corresponding n cantilever beams 2 to swing inward until the ring track segment 12 is turned inside out on the foundation floor 1. In this step, each winch 18 first reels in and pulls the cantilever beam 2 to turn inside out. When each cantilever beam 2 and the traction rope 19 are straightened, as shown in FIG. Figure 2 , a worker hooks the remaining lower lifting ear 4 with a hook and pulls it inward to make the cantilever beam 2 continue to turn inward and pass the vertical state. After that, the winch 18 releases the line, and the cantilever beam 2 automatically continues to turn inward under its own weight until the lifting ring 17 of the cantilever beam 2 abuts against the floor slab and turns inward into place.

[0057] The worker stands on the foundation floor 1 to disassemble the inwardly turned ring rail segment 12 into n I-beam hanging rails 12 . 1 and removes the n I-beam hanging rails 12 . 1 from the corresponding cantilever beams 2 .

[0058] Use the same steps to remove the next ring rail segment 12.

[0059] It is common sense that the circular track is divided into straight sections and arc sections. The number of arc sections is small and the distance is short, and the straight sections are the mainstream of the circular track. Therefore, the present application improves the construction process of the straight sections that occupy most of the circular track, thereby greatly improving the overall construction process of the circular track.
