Description

Technical Field

[0001] The present application relates to the technical field of steel structure construction, and in particular to a steel roof hoisting device and a hoisting method. Background Art

[0002] The frame structure uses two rows of concrete structural columns as supports, and truss-shaped steel roofs are hoisted one by one on the concrete structural columns to eventually form an overall load-bearing skeleton of the steel structure.

[0003] In actual construction, after each steel roof is assembled on the ground, a crane is used to lift the steel roof to the top of the concrete column, and the two ends of the steel roof are fixedly connected to the embedded parts on the top of the concrete column. For construction environments where the construction area is narrow and it is not convenient to set up a crane, a lifting device is usually fixed on the top of the concrete column to lift the steel roof.

[0004] A lifting device is arranged above the two concrete columns, and the hooks of the two lifting devices are fixed to both ends of the assembled steel roof. The steel roof is lifted synchronously by the two lifting devices, thereby realizing the lifting of the steel roof.

[0005] Since the lifting device lifts the steel roof upwards through the slings, the slings are prone to shake during the lifting process, causing the steel roof to shake; the steel roof is large in size and heavy in weight. If the steel roof shakes, it is easy to hit the concrete structure columns and cause damage to the concrete structure columns; or the shaking of the steel roof will exert lateral pressure on the lifting device, making it difficult for the lifting device to maintain stable force, thus causing construction accidents. Summary of the invention

[0006] In order to improve the situation that the steel roof is prone to shaking during the lifting process, the present application provides a steel roof lifting device.

[0007] The present application provides a steel roof hoisting device, which adopts the following technical solution:

[0008] A steel roof hoisting device, comprising:

[0009] A hoisting structure is used to be installed on the top of a concrete structure column. The hoisting structure includes a fixing assembly and a lifting device. The fixing assembly is used to be fixedly connected to the concrete structure column. The lifting device is slidably arranged on the fixing assembly, and the lifting device is used to lift the steel roof;

[0010] A limiting device, the limiting device comprising a track fixed on the side wall of the concrete structure column and an anti-sway component slidably arranged in the track;

[0011] The lifting device comprises a sling used for connecting with the steel roof, and a connecting piece used for connecting with the anti-sway component is fixed on the sling.

[0012] By adopting the above technical solution, when hoisting a steel roof, the slings of the two lifting devices are respectively connected to the two ends of the steel roof, and the lifting devices are fixed by the fixing components on the two concrete structural columns, and the steel roof is lifted upward by the lifting devices;

[0013] The anti-sway component on the limiting component is fixedly connected to the sling. When the steel roof is lifted upward, the anti-sway device slides along the track. At this time, the limiting effect of the track can limit the sway of the sling, thereby reducing the sway of the steel roof when it is lifted, so as to increase the safety during the lifting process of the steel roof.

[0014] Optionally, the anti-sway component includes a sliding block slidably disposed in the track, a connecting rod is fixed to the sliding block, and a locking component for detachably connecting to the connecting piece is fixed to one end of the connecting rod away from the sliding block.

[0015] By adopting the above technical solution, the locking assembly is fixedly connected to the connecting piece to achieve position fixation between the sling and the anti-sway assembly, thereby controlling the sway of the sling through the anti-sway assembly; when the sling lifts the steel roof upward, the connecting piece rises accordingly, driving the connecting rod and the sliding block to slide upward along the track.

[0016] Optionally, the locking assembly includes a vertical plate fixed on the connecting rod, the plane where the vertical plate is located is perpendicular to the axis of the connecting rod, two parallel and spaced card plates are fixed on the connecting plate, the gap between the two card plates is used for the connection of the connecting piece, and fixing parts for locking the card plates and the vertical plates are provided between the vertical plate and the card plates.

[0017] By adopting the above technical solution, after the card plate is inserted between the two vertical plates, the position of the card plate and the vertical plate can be fixed by the fixing parts. The fixing parts can be bolts and nuts passing through the vertical plates and the card plate. The locking assembly of the present application is simple and quick to use, and can quickly fix the position between the card plate and the anti-sway assembly.

[0018] Optionally, short rods are threadedly connected to the side walls on both sides of the card plate, the short rods are arranged perpendicular to the side walls of the card plate, and a long rod is fixed to one end of the short rod away from the card plate, the long rod is perpendicular to the short rod, and the long rod and the short rod are in the same horizontal plane;

[0019] Two long rods on the same axis at both ends of a steel roof are detachably connected.

[0020] By adopting the above technical scheme, when the steel roof is lifted, if the lifting heights at both ends of the steel roof are inconsistent, it is easy to cause the steel roof to tilt, making the overall force of the steel roof unstable and causing construction accidents; short rods and long rods are set, and the short rods and long roots are fixedly connected to both sides of the clamping plate, so that the long rods and short rods at both ends of the steel roof are spliced ​​to form a quadrilateral frame; when the height planes at the two ends of the steel roof are different, the bending moment at the corner of the quadrilateral frame is too large, thereby limiting the higher end of the steel roof from continuing to lift upward. At this time, the construction personnel can readjust the lifting heights at both ends of the steel roof, so that the two ends of the steel roof are at the same horizontal height, and then continue to lift; the short rods and long rods can reduce the occurrence of inconsistent heights at the two ends of the steel roof during the lifting process of the steel roof, thereby improving the stability and safety of the steel roof frame during the lifting process.

[0021] Optionally, a plurality of limiting components are arranged at intervals along the track of the track, and the limiting components include two rotating plates rotatably connected to the side walls of the track, and the two rotating plates are arranged at intervals;

[0022] Under the push of the sliding block, the rotating plate can only rotate toward the top of the concrete structure column, and the rotating plate remains horizontal in a natural state.

[0023] By adopting the above technical solution, the sliding block can only slide upward along the track and cannot move downward along the track. When the heights of the two ends of the steel roof are inconsistent, in order to resist the twisting deformation at the connection between the short rod and the long rod, the sliding block can move downward to adapt to the height difference, thereby reducing the bending moment at the connection between the upper rod and the short rod; if the sliding block can only slide upward, the ability of the sliding block to move downward to resist deformation is reduced, so that the long rod and the short rod can better limit the height displacement at both ends of the steel roof.

[0024] Optionally, the fixing assembly includes a plurality of corbels fixed to opposite side walls of the concrete structure column, and the corbels are fixed to the adjacent side walls of the track;

[0025] A column is fixed on each of the corbels, and a lifting frame is fixed on the end of the column away from the corbel. A plurality of parallel extension beams extend from the side of the lifting frame close to the steel roof, and sliding ways are fixed to the ends of the plurality of extension beams. The length direction of the sliding ways is perpendicular to the length direction of the extension beams, and the lifting device is slidably arranged on the sliding ways.

[0026] By adopting the above technical solution, the arrangement of corbels, columns and lifting frames can enhance the strength of the fixed components, so that the lifting device arranged on the fixed components can bear the gravity of the steel roof and smoothly lift the steel roof; an extended beam is arranged so that when the lifting device lifts the steel roof upward, the steel roof is not easy to interfere with the concrete structural column and can be lifted upward smoothly; a sliding path is arranged to provide a fixed platform for the lifting device.

[0027] Optionally, the slideway is provided with a long hole along its length direction for the sling to pass through, the long hole does not pass through both ends of the slideway, and the slideway is provided with a positioning component for fixing the position of the lifting device.

[0028] By adopting the above technical solution, when the lifting device is fixed on the sliding track, the sling can pass through the long hole and be fixed on the steel roof; the long hole is provided so that the lifting device can slide along the long hole, and when the steel roof is lifted upward, the position of the lifting device is locked by using the positioning assembly. When the steel roof is lifted to the designed height, the construction workers continue to assemble the structures at both ends of the steel roof in the air, so that the steel roof can be supported on the top of the concrete structure column.

[0029] Usually, embedded parts are set on the top of concrete structure columns, and the steel roof is fixed to the concrete structure columns through the embedded parts. When fixing the steel roof to the embedded parts, it is necessary to slide the steel roof horizontally so that the position of the steel roof and the embedded parts are aligned before the steel roof can be fixed. After the steel roof is lifted to the designed position, the connection between the anti-sway component and the sling is released. At this time, the lifting device can be moved along the long hole to achieve the horizontal position adjustment of the steel roof.

[0030] Optionally, the positioning assembly includes two limit blocks, both ends of the limit blocks are provided with a first threaded hole, a plurality of second threaded holes are provided on the sliding track at intervals along the length direction of the sliding track, and the second threaded holes are arranged in two rows, and the positioning assembly also includes high-strength bolts that are threadedly connected to the first threaded hole and the second threaded hole at the same time.

[0031] By adopting the above technical solution, when the position of the lifting device needs to be fixed, the limit blocks are placed on both sides of the lifting device, and the limit blocks are fixed to the sliding track by high-strength bolts. By reasonably setting the spacing of the second threaded holes, when the two limit blocks are fixed on the sliding track, the lifting device is clamped between the two limit blocks, so that the lifting device can stably lift the steel roof upward.

[0032] Optionally, sliding grooves are provided on both sides of the long hole in parallel and at intervals;

[0033] A sliding structure is fixed on the lifting device, and the sliding structure includes two sliding blocks respectively inserted into the sliding grooves;

[0034] A driving device for driving the lifting device to slide along the sliding path is fixed on the side wall of the lifting device.

[0035] By adopting the above technical solution, when it is necessary to adjust the position of the lifting device so that the lifting device slides along the long hole, the fixation of one of the limit blocks is released, and the lifting device is driven to slide along the long hole by the driving device. The setting of the slider can limit the moving path of the lifting device and facilitate the movement of the lifting device; the setting of the slide groove can limit the displacement of the lifting device, so that the lifting device is not easy to leave the sliding path and cause serious construction accidents.

[0036] In summary, the present application includes at least one of the following beneficial effects:

[0037] 1. The present application sets up an anti-sway component, so that when the lifting device lifts the steel roof upward, it can limit the sway of the sling, alleviate the sway during the steel roof hoisting process, and make the construction process more stable and safe;

[0038] 2. Set a short rod and a long rod on the pallet, and connect and fix the two long rods opposite to each other. When the lifting heights of the two ends of the steel roof are inconsistent, the positions of the long rod and the short rod are locked, making it difficult to continue to lift the steel roof upwards, thereby reducing the occurrence of inconsistent lifting heights at both ends of the steel roof during the steel roof lifting process and reducing the occurrence of construction accidents;

[0039] 3. Long holes are set on the sliding track so that the lifting device can slide along the long holes. When the steel roof is lifted to the designed position and assembled in the air, the steel roof can be smoothly installed on the concrete structure column by sliding the steel roof horizontally, and the operation is simple and convenient.

DETAILED DESCRIPTION

[0045] The following is combined with Figure 1-4 This application is described in further detail.

[0046] The steel roof hoisting equipment disclosed in the embodiment of the present application is as follows: Figure 1 , taking the hoisting of a steel roof 8 as an example for explanation, concrete structural columns 7 for supporting the steel roof 8 are cast at both ends of the steel roof 8.

[0047] Reference Figure 1 A steel roof lifting device includes a lifting structure arranged on the top of a concrete structure column 7, the lifting structure includes a fixing component 1 fixed on the top of the concrete structure column 7, and a lifting device 2 for lifting a steel roof 8, and the lifting device 2 is installed on the fixing component 1.

[0048] Reference Figure 1 and Figure 2 The fixing assembly 1 includes four corbels 11 fixed to the side walls of the concrete structural column 7. The corbels 11 are cast-in-place concrete structures, and the corbels 11 are integrally cast with the concrete structural column 7. The steel bars in the corbels 11 are tied and fixed to the steel cage of the concrete structural column 7. The corbels 11 are arranged on a plane parallel to the plane where the concrete structural column 7 and the steel roof 8 are located, and the four corbels 11 are evenly and symmetrically arranged on two opposite side walls of the concrete structural column 7. The corbels 11 are fixed with columns 12, which are made of steel. The columns 12 are welded to the steel bars in the corbels 11, and the columns 12 are partially cast in the corbels 11. A lifting frame 13 is fixed to the end of the column 12 away from the corbel 11, and the lifting frame 13 is fixedly connected to the ends of multiple columns 12 at the same time, and the lifting frame 13 is a square frame structure; two parallel extension beams 14 are extended from the side of the lifting frame 13 close to the steel roof 8, and a sliding track 15 is fixed to the end of the extension beam 14 away from the lifting frame 13, and the sliding track 15 is a square column structure, and the length direction of the sliding track 15 is perpendicular to the length direction of the extension beam 14.

[0049] Reference Figure 2The columns 12, the hoisting frame 13, the extension beam 14 and the slideway 15 are all made of Q335B steel, and the columns 12 and the hoisting frame 13, and the extension beam 14 and the slideway 15 are welded and fixed. The welds are all full penetration welds with a first-class weld grade, and ultrasonic flaw detection is carried out as required, so that the strength of the fixing component 1 can withstand the tension and bending moment applied when the steel roof 8 is lifted.

[0050] Reference Figure 1 and Figure 2 The slideway 15 is provided with a long hole 151 along the length direction of the slideway 15, and the two ends of the long hole 151 do not penetrate the slideway 15, and the lifting device 2 is installed on the slideway 15. The lifting device 2 includes a lifter 24 and a sling 21, one end of the sling 21 is fixed to the lifter 24, and the other end is used to be tied to the end of the steel roof 8, so as to realize the function of lifting the steel roof 8 upward through the lifting device 2.

[0051] Reference Figure 1 and Figure 2 The lifting device 2 can slide along the long hole 151. Specifically, slide grooves 153 are arranged at intervals on both sides of the long hole 151 in parallel. The length of the slide groove 153 is shorter than the length of the long hole 151. A sliding structure 23 is fixed on the lifter 24. The sliding structure 23 includes a mounting plate 232 fixed on the lifter 24. Both ends of the mounting plate 232 are respectively integrally formed with sliders 231 for being inserted into the slide groove 153. The slider 231 is against the bottom wall of the slide groove 153. A driving device is also connected to the side wall of the mounting plate 232. The driving device is specifically a winch that can drag the lifting device 2 to slide along the slide groove 153. The winch is arranged on the ground and the lifting device 2 is moved by pulling the cable. In order to enable the winch to operate normally, a roller for the cable to slide can also be provided at the end of the sliding track 15. The driving device and the roller are not shown in the figure. The present application records only one case of the driving device. Other devices that can drive the lifting device 2 to move can also be used as the driving device of the present application.

[0052] Reference Figure 1 and Figure 2, a positioning assembly is also provided on the sliding track 15, and the positioning assembly includes two limit blocks 5, the limit blocks 5 are rectangular steel blocks, and the positions near the two ends of the limit blocks 5 are provided with first threaded holes 51, and only one limit block 5 is shown in the figure. The sliding track 15 is provided with a plurality of second threaded holes 152 spaced along the length direction of the sliding track 15, and the second threaded holes 152 are provided in two rows. When the lifting device 2 lifts the steel roof 8 upward, the lifting device 2 needs to be locked in position. At this time, the limit block 5 is moved to align the first threaded hole 51 with the second threaded hole 152, and the high-strength bolt 6 is connected by threading in the first threaded hole 51 and the second threaded hole 152, so that the position of the limit block 5 and the sliding track 15 can be fixed. Only one high-strength bolt 6 is shown in the figure. The spacing between the two adjacent second threaded holes 152 is reasonably set, so that when the positions of the two limit blocks 5 are fixed, the lifting device 2 can be clamped between the two limit blocks 5 to achieve the position locking of the lifting device 2.

[0053] Reference Figure 3 and Figure 4 The steel roof hoisting device of the present application further includes a limiting device, which includes a track 3 fixed on opposite side walls of the concrete structural columns 7 at both ends of the steel roof 8, and an anti-sway component 4 slidably arranged in the track 3. The anti-sway component 4 includes a sliding block 41 sliding in the track 3, a connecting rod 42 is fixed on the side wall of the sliding block 41, and a locking component 43 is fixed to the end of the connecting rod 42 away from the sliding block 41. The locking assembly 43 includes a vertical plate 431 fixed to the connecting rod 42, and the plane where the vertical plate 431 is located is perpendicular to the length direction of the connecting rod 42. Two parallel and spaced-apart clamping plates 432 are fixed on the surface of the vertical plate 431; a connecting piece 22 is fixed on the sling 21, and the connecting piece 22 is specifically a steel plate that can be inserted into the gap between the two clamping plates 432. Both the clamping plate 432 and the connecting piece 22 are provided with through holes. When the connecting piece 22 is inserted between the two clamping plates 432, the through holes on the clamping plate 432 are connected to the through holes on the connecting piece 22. A fixing piece 44 for locking the positions of the clamping plate 432 and the connecting piece 22 is provided between the clamping plate 432 and the connecting piece 22, and the fixing piece 44 can be a bolt and nut.

[0054] Reference Figure 1 and Figure 3 The side walls of the clamping plate 432 are both threadedly connected with short rods 45, which are perpendicular to the side walls of the clamping plate 432. The end of the short rod 45 away from the clamping plate 432 is fixed with a long rod 46, which is in the same horizontal plane as the short rod 45 and is arranged perpendicular to the short rod 45. The end of the long rod 46 away from the short rod 45 is provided with a threaded section, and the two long rods 46 on the same axis at both ends of a steel truss are connected through a steel sleeve.

[0055] Reference Figure 1 and Figure 3When the steel roof 8 is lifted, the long rods 46 on both sides of the steel roof 8 are connected one by one, so that the short rods 45 and the long rods 46 form a rectangular frame. When the steel roof 8 is lifted, if the lifting heights of the two ends of the steel roof 8 are inconsistent, the rectangular frame formed by the short rods 45 and the long rods 46 bears the bending moment. At this time, the positions of the short rods 45 and the long rods 46 are stuck, making it difficult for the displacement difference at the two ends of the steel roof 8 to continue to increase, thereby limiting the further lifting of the steel roof 8. The long rods 46 and the short rods 45 can limit the two ends of the steel roof 8 to be at the same horizontal height when the steel roof 8 is lifted.

[0056] Reference Figure 3 Furthermore, a plurality of limiting components are arranged at intervals along the length direction of the track 3, and the limiting components include two rotating plates 31 at the same level, the two rotating plates 31 are arranged at intervals, and the two rotating plates 31 are rotatably connected to the side walls of the track 3 respectively. The rotating plates 31 naturally remain horizontal, and under the push of the sliding block 41, the rotating plates 31 can only rotate toward the top of the concrete structure column 7. The limiting component is provided so that the sliding block 41 can only be lifted upwards and is difficult to lower. When the lifting heights at both ends of the steel roof 8 are inconsistent, it is difficult to slide downwards through the sliding block 41 to resist the bending moment and deformation at the short rod 45 and the long rod 46. In addition, when the lifting heights at both ends of the steel roof 8 are inconsistent, causing the anti-sway component 4 to get stuck, it is necessary to release the connection between the locking component 43 and the sling 21. After the connection between the locking component 43 and the sling 21 is released, the limiting component makes it difficult for the locking component 43 to slide along the track 3, so that the construction personnel can adjust the position of the steel roof 8 and then fix the locking component 43 to the sling 21 again.

[0057] The implementation principle of a steel roof lifting device in an embodiment of the present application is: first, the slings 21 on the two concrete structural columns 7 are tied to the two ends of the steel roof 8, and the connecting piece 22 is inserted between the two clamping plates 432, and the positions of the clamping plates 432 and the connecting piece 22 are locked by the fixing piece 44. At this time, the position of the lifting device 2 is locked between the two limit blocks 5.

[0058] The short rods 45 and the long rods 46 are threadedly connected to the side walls of the clamping plate 432, and the two long rods 46 on the same axis are connected through steel sleeves, so that four groups of short rods 45 and long rods 46 are surrounded by a rectangular frame, and the two ends of the steel roof 8 are lifted upward at the same time by the lifting device 2 until the steel roof 8 rises to the designed height.

[0059] During the lifting process of the steel roof 8, since the sling 21 is fixed to the anti-sway component 4 through the connecting piece 22, the sliding block 41 slides along the track 3, making it difficult for the anti-sway component 4 to move left and right, thereby limiting the shaking of the sling 21, which can improve the stability of the sling 21 during lifting, reduce the shaking of the steel roof 8 during the lifting process, and improve the stability and safety of the steel roof 8 during lifting.

[0060] The short rod 45 and the long rod 46 are arranged so that when the steel roof 8 is lifted, if the lifting heights of the two ends of the steel roof 8 are inconsistent, the rectangular frame composed of the long rod 46 and the short rod 45 is stuck, thereby limiting the further lifting of the steel roof 8. This can reduce the situation in which the steel roof 8 is tilted due to a large height difference between the two ends of the steel roof 8 during the lifting process.

[0061] When the steel roof 8 is lifted to above the concrete structural columns 7, the construction workers continue to splice the remaining structure of the steel roof 8 at both ends of the existing steel roof 8 structure. When the steel roof 8 structure is assembled, the two ends of the steel roof 8 can be fixed to the tops of the two concrete structural columns 7. The steel roof 8 structure is supported by the concrete structural columns 7. Usually, embedded plates for fixed connection with the steel roof 8 are embedded in the tops of the concrete structural columns 7.

[0062] The track 3 is not closed above, so when the steel roof 8 is lifted to the top of the concrete structure column 7 by the lifting device 2, the sliding block 41 has been separated from the track 3, and the construction personnel can release the fixation between the anti-sway component 4 and the connecting piece 22 in the air. When it is necessary to adjust the position of the steel roof 8 horizontally so that the steel roof 8 is aligned with the embedded plate above the concrete structure column 7, the limit block 5 in the direction where the steel roof 8 needs to slide can be released, and the driving device can be used to drive the lifting device 2 to slide along the slide groove 153 until the end of the steel roof 8 is directly above the embedded plate. At this time, the steel roof 8 is lowered again by the lifting device 2 so that the steel roof 8 is against the embedded plate and the steel roof 8 is connected and fixed to the embedded plate to complete the hoisting of the steel roof 8.

[0063] After the hoisting is completed, the track 3 is removed from the concrete structure column 7, and the fixing assembly 1 is cut from the concrete structure column 7, thus completing the entire construction procedure of the steel roof truss.

[0064] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
