Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated beam hoisting construction, in particular to a prefabricated beam through-beam hoisting device. Background Art

[0002] As the scale of urban development continues to expand, land resources are becoming increasingly scarce, and industrial land is in short supply. The traditional factory development model is putting increasing pressure on companies to obtain industrial survival space. In the context of reduction, promoting industrial relocation and creating smart manufacturing space is an inevitable way to break the constraints of industrial development space, and multi-story industrial factories are gradually becoming a trend. Due to the requirements of functional use, multi-story industrial factories often use spans of more than 15m. The traditional practice of large-span concrete structure factory floors is to use cast-in-place concrete beam-slab structures. In recent years, with the promotion and application of prefabricated technology, construction costs have been greatly reduced, and prefabricated beams have been increasingly used in large-span floors and roofs.

[0003] Due to the functional requirements of span and load, the prefabricated beams of industrial plants generally have large spans, large cross-sections, and heavy weight, which brings great difficulties to the hoisting construction of prefabricated beams. How to complete the hoisting construction safely, efficiently, and quickly is a technical problem that needs to be solved urgently in this field.

[0004] The traditional hoisting construction of prefabricated beams in large-span industrial plants usually involves pre-embedding several lifting rings at equal intervals and symmetrically on the top surface of the prefabricated beams. Each lifting ring on the prefabricated beam is equivalent to only one lifting point. In order to maintain balance, the number of lifting rings is an even number. Then the wire rope is folded in half and the two ends are connected to the two lifting rings at symmetrical positions on the prefabricated beam. Because there are many lifting points, the angles formed by each wire rope and the surface of the prefabricated beam are inconsistent during hoisting. The single-machine hoisting method cannot ensure that each wire rope and lifting point are evenly stressed, which easily causes individual wire ropes to be unstressed or stressed too much or too little, which is inconsistent with the theoretical working conditions and poses a great risk to hoisting safety. At the same time, it is difficult for the hook of a single crane to lift all the wire ropes on the lifting rings of the prefabricated beam at the same time, so two cranes are required to lift the wire ropes on the lifting rings of the prefabricated beams separately, and two cranes are used for lifting. The disadvantage of this lifting method is that the installation of lifting equipment such as wire ropes is too cumbersome, and the double-machine lifting requires high coordination for lifting. When the precast beams are lifted by two machines, in order to ensure the load balance of the two cranes, the lifting efficiency is low, and the pre-buried round steel lifting rings will affect the subsequent installation of steel bars in the overlapping area of ​​the precast beams. After the precast beams are lifted, all the lifting rings need to be welded and cut off, which is time-consuming and labor-intensive.

[0005] Therefore, there is an urgent need for a prefabricated beam through-beam hoist that can effectively realize single-machine hoisting, simplify the hoisting steps, speed up hoisting, and reduce costs. Utility Model Content

DETAILED DESCRIPTION

[0037] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below in conjunction with the accompanying drawings through specific implementation methods. Figure 2 The orientation is used as a reference.

[0038] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0039] See attached Figure 1-4 As shown, the utility model provides a prefabricated beam through-beam hanger, which is applied to the prefabricated beam 5 of the large-span industrial plant, and cooperates with the crawler crane 4 and the wire rope for hoisting construction. During the manufacturing process of the prefabricated beam 5, a plurality of sleeves 53 are pre-buried in the horizontal direction, and the through-beam hanger 6 passes through the sleeve 53. The through-beam hanger 6 includes a hanging rod 61 for passing through the sleeve 53, an end cover 65 for fixing the hanging rod 61 in the sleeve 53, and a pin 62 for limiting the wire rope sleeved on the hanging rod 61. Annular grooves 613 are arranged at both ends of the hanging rod 61 along the circumferential direction, and the annular grooves 613 are used for sleeved wire ropes. The end cover 65 is detachably connected to the end of the hanging rod 61, one end of the pin 62 is connected to the end cover 65 through an elastic connecting rope 64, the other end of the pin 62 away from the elastic connecting rope 64 passes through the hanging rod 61 and is plugged into the hanging rod 61, the pin 62 is located on the side of the annular groove 613 near the end of the hanging rod 61, and the steel wire rope sleeved in the annular groove 613 is limited by the pin 62 plugged into the hanging rod 61.

[0040] By setting a beam-penetrating hanger 6 to pass through the prefabricated beam 5 and sleeved with steel wire ropes at both ends of the beam-penetrating hanger 6, it is possible to avoid pre-embedding a large number of lifting rings on both sides of the prefabricated beam 5, thereby simplifying the lifting steps. At the same time, the prefabricated beam 5 can be lifted by only one crawler crane 4, without the need for two crawler cranes 4 to cooperate and maintain balance, and the lifting speed is faster and the cost is low.

[0041] The suspension rod 61 is cylindrical in structure and is made of 45# manganese steel. The processing length of the suspension rod 61 is determined according to the width of the prefabricated beam 5. The length of the suspension rod 61 = the width of the prefabricated beam 5 + 300mm. External threads 612 for connecting the end caps 65 are provided at both ends of the suspension rod 61. The width of the external threads 612 is 20mm.

[0042] The end cap 65 is a round cap-shaped structure, and one end of the end cap 65 is provided with a groove inwardly, and the inner side wall of the groove has an internal thread 651, and the internal thread 651 matches the external thread 612 of the suspension rod 61, so that the end cap 65 can be fixed to the end of the suspension rod 61 through a threaded connection. By providing the end cap 65 threadedly connected to the suspension rod 61, the suspension rod 61 passing through the prefabricated beam 5 can be fixed to prevent the suspension rod 61 from slipping out of the sleeve 53 of the prefabricated beam 5.

[0043] A pin hole 611 with a diameter of 2 cm is provided 50 mm away from the end of the suspension rod 61 . The pin hole 611 is arranged along the radial direction of the suspension rod 61 , that is, along the vertical direction of the suspension. The pin hole 611 is used to plug the pin 62 .

[0044] The latch pin 62 is inserted into the latch pin hole 611. A stopper pin 63 is provided in the middle of the latch pin 62 for limiting the position of the latch pin 62. The stopper pin 63 is made of round steel with a length of 5 cm and a diameter of 1 cm. The stopper pin 63 is connected to the latch pin 62 by perforation welding. The stopper pin 63 is provided on the latch pin 62 to prevent the latch pin 62 from slipping off from the lower end of the latch pin hole 611.

[0045] The latch 62 is connected to the end cover 65 via an elastic connecting rope 64. A first connecting ring is provided at one end of the end cover 65 connected to the elastic connecting rope 64. A second connecting ring is provided at one end of the latch 62 connected to the elastic connecting rope 64. Both the first connecting ring and the second connecting ring are used to connect the elastic connecting rope 64. The elastic connecting rope 64 is a retractable spring rope. One end of the elastic connecting rope 64 is linear and the other end of the elastic connecting rope 64 is spiral. The latch 62 is connected to the end cover 65 by providing the elastic connecting rope 64. When the latch 62 is not inserted into the latch hole 611, the elastic connecting rope 64 remains in a contracted state and has a short length. When the latch 62 is inserted into the latch hole 611, the elastic connecting rope 64 can be lengthened according to actual installation requirements, so that the latch 62 can move in a larger range, which is convenient for disassembly and installation.

[0046] The annular groove 613 is set at a position 80 mm away from the end of the suspension rod 61. The width of the annular groove 613 is 60 mm. The annular groove 613 is used to sleeve the steel wire rope. The combination of the annular groove 613 and the pin 62 can achieve the fixing and limiting of the steel wire rope.

[0047] The beam-penetrating sling 6 provided by the utility model is different from the single lifting point of the lifting ring. Both ends of each beam-penetrating sling 6 are equivalent to having two symmetrical lifting points at the same time. When lifting the prefabricated beam 5 of the same span, the traditional lifting ring lifting method needs to use 8 lifting rings for lifting. The prefabricated beam 5 needs a total of 4 steel wire ropes folded in the middle, and the two ends are respectively connected to the symmetrical lifting rings. It is difficult for a crawler crane 4 to lift it at the same time. After replacing it with the beam-penetrating sling 6, it is only necessary to install 4 beam-penetrating slings 6 on the prefabricated beam 5. The 4 beam-penetrating slings 6 need 4 steel wire ropes 3 folded in the middle to complete the connection of the slings. The two ends of the folded steel wire ropes 3 are respectively connected to the two sides of the beam-penetrating sling 6. Because the lifting points on both sides of the beam-penetrating sling 6 are symmetrical and the force is consistent, the 4 folded steel wire ropes 3 can be connected to the 2 folded steel wire ropes 1 through the shackle 2, and the 2 folded steel wire ropes 1 are hung on the hook 41 of the crawler crane 4. Therefore, the prefabricated beam 5 can be hoisted by only one crawler crane 4 .

[0048] The prefabricated beam through-beam hoist 6 provided by the utility model is inserted into the prefabricated beam 5, replacing the traditional pre-buried lifting rings on both sides of the prefabricated beam 5. Steel wire ropes are installed at both ends of the through-beam hoist 6, and cooperate with the crawler crane 4 to realize the hoisting construction of the prefabricated beam 5. Through the setting of the through-beam hoist 6, the prefabricated beam 5 can be hoisted using only one crawler crane 4.

[0049] By combining the suspension rod 61 and the end cover 65 , the beam-penetrating suspension device 6 can be kept in the prefabricated beam 5 and will not slip out of the prefabricated beam 5 during the subsequent installation process.

[0050] By inserting the latch pin 62 on the suspension rod 61, the steel wire rope sleeved in the annular groove 613 can be limited to avoid displacement of the steel wire rope.

[0051] By providing a retractable elastic connecting rope 64 between the latch 62 and the end cover 65, the possibility of component loss is reduced.

[0052] The prefabricated beam hoist of the utility model is convenient to install and disassemble, safe and reliable, and greatly improves the construction efficiency. The large-span prefabricated beam 5 only needs a single machine for hoisting and construction, which has a faster construction speed and lower cost.

[0053] See attached Figure 5-8 As shown, the hoisting construction method using the beam-penetrating sling 6 comprises the following steps:

[0054] Step 1: making a prefabricated beam 5 and embedding a sleeve 53 in the prefabricated beam 5;

[0055] The precast beam 5 is provided with anchoring steel bars 52 which are exposed to the precast beam 5 to facilitate the subsequent anchoring construction. The upper end of the precast beam 5 is provided with a plurality of overlapping stirrups 51 .

[0056] The position and number of the embedded sleeves 53 are selected according to actual needs to ensure that the hoisting holes meet the requirements. In this embodiment, four PVC sleeves 53 are embedded in the prefabricated beam 5 .

[0057] Step 2: After the precast beam 5 is cured to the hoisting strength, the precast beam 5 is transported to the hoisting area;

[0058] The precast beam 5 is hoisted from the beam factory onto a flatbed truck, and iron chains are used to secure the precast beam 5 firmly to prevent the precast beam 5 from tipping over during transportation.

[0059] Step 3: Install the beam-penetrating hanger 6;

[0060] The hanging rod 61 is passed through the sleeve 53 , and end caps 65 are screwed onto both ends of the hanging rod 61 .

[0064] Step 5: Connect the wire rope to the beam-penetrating sling 6;

[0065] The rope loops at both ends of each auxiliary steel wire rope 3 are correspondingly placed in the annular grooves 613 at both ends of each suspension rod 61, and the latch 62 is inserted from top to bottom into the latch holes 611 at both ends of the suspension rod 61. After the auxiliary steel wire rope 3 is connected to the prefabricated beam 5, the angle between the main steel wire rope 1, the auxiliary steel wire rope 3 and the prefabricated beam 5 is 45-60 degrees.

[0066] Step 6: Install the lifting traction rope 7 on the prefabricated beam 5

[0067] One end of the hoisting traction rope 7 is tied to the superimposed stirrup 51 at the upper end of the prefabricated beam 5, and the other end is pulled by the hoisting personnel. The hoisting traction rope 7 is a hemp rope with a rope diameter of 12mm.

[0068] Step 7: lifting the prefabricated beam 5;

[0069] Before the formal lifting, remove the fixing iron chain of the prefabricated beam 5 on the flatbed truck.

[0070] Then the precast beam 5 is hoisted and stopped when the precast beam 5 is 500-800mm off the ground, and further inspection is carried out to check whether all conditions are normal. If normal, the hoisting is continued. The hoisting personnel control the swinging direction of the precast beam 5 through the hoisting traction rope 7 to ensure safety.

[0071] Step 8: Adjust the landing position of the prefabricated beam 5 so that the prefabricated beam 5 is installed to the preset position;

[0072] When the precast beam 5 is hoisted to a height of 500 mm from the designed position, the precast beam 5 is slowly lowered, and the position of the precast beam 5 is adjusted by the hoisting traction rope 7 until the precast beam 5 is accurately hoisted to the designated position.

[0073] Step 9: Remove the lifting device and complete the lifting of the prefabricated beam 5;

[0074] Check whether the precast beam 5 is in the correct position. If it is correct, remove the latch 62, the hanging rod 62, the main wire rope 1, the auxiliary wire rope 3 and other hanging equipment in turn.

[0076] Four PVC sleeves 53 with a diameter of 110 mm are embedded in the precast beam 5 before pouring, which are used as lifting holes. The hanging rod 61 is made of 45# manganese steel, with a diameter of 80 mm and a length of 700 mm. The main steel wire rope 1 is a 6×37+FC φ60mm×20m fiber core steel wire rope, the auxiliary steel wire rope 3 is a 6×37+FC φ48mm×12m fiber core steel wire rope, and the shackle 2 is a 25T American shackle.
