Description

Technical Field

[0001] The present application relates to the technical field of prefabricated steel bar frameworks for T - beams, and specifically to an assembled hanging rack for hoisting prefabricated steel bar frameworks of T - beams. Background Art

[0002] In the existing construction field, the hoisting of prefabricated steel bar frameworks for T - beams is a crucial construction link. The hoisting hanging rack for prefabricated steel bar frameworks of T - beams is a special equipment for hoisting and installing T - beams. T - beams are usually used in structures such as bridges and buildings, and their prefabricated steel bar frameworks need to be accurately positioned and installed by hoisting equipment during construction.

[0003] However, in the actual operation process, we face many problems and challenges. Traditional hoisting hanging racks are in a prefabricated form, with a small scope of application. Once welded, they are only applicable to the size and shape of one type of prefabricated steel bar framework of T - beams. At the same time, due to the high equipment transportation and storage costs after prefabrication, in view of the above - mentioned actual technical problems, an assembled hanging rack for hoisting prefabricated steel bar frameworks of T - beams is proposed to solve the above problems. Utility Model Content

[0004] In view of the deficiencies of the prior art, the present application provides an assembled hanging rack for hoisting prefabricated steel bar frameworks of T - beams, which has the advantages of being able to select appropriate hanging rack segments for assembly and use according to the size and shape of the prefabricated steel bar frameworks of T - beams, and having strong applicability.

[0005] To achieve the above object, the present application provides the following technical solution: An assembled hanging rack for hoisting prefabricated steel bar frameworks of T - beams, including one upper chord rod and two lower chord rods. A truss is fixedly connected between the two lower chord rods and the upper chord rod.

[0006] Both ends of the upper chord rod and the lower chord rods are provided with pin holes for assembly connection. A number of independent hanging racks formed by the upper chord rod, the lower chord rods and the truss are provided. Adjacent hanging racks are spliced through pins penetrating through the pin holes.

[0007] A threaded rod is arranged on the pin. A threaded sleeve located in the inner cavity of the pin is threadedly connected to the outer part of the threaded rod. An extension rod is also fixedly installed on the outer part of the threaded sleeve. A connecting rod is rotatably installed at the end of the extension rod. A pin penetrating through and extending to the outside of the pin is rotatably installed at the end of the connecting rod far from the extension rod.

[0008] Further, the upper chord rod and the two lower chord rods are arranged in a triangular structure, and the truss fixedly connects the upper chord rod and the lower chord rods and between the two lower chord rods respectively.

[0009] Further, the trusses are continuously arranged in a V shape between the upper chord and the lower chord.

[0010] Further, the upper chord and the two lower chords are both formed by butt-welding a pair of channel steels.

[0011] Further, a hanging structure is provided on the upper chord. The hanging structure includes a gantry crane hook and a steel wire rope for connection. Multiple hanging structures are evenly distributed on the upper chord.

[0012] Further, an extension ring is integrally connected to the middle of the shaft pin, and the cross-sections of the shaft pin and the shaft pin hole are both rectangular.

[0013] Further, two sections of threads with opposite thread directions are provided on the outer part of the threaded rod. Two thread sleeves are threadedly connected to the outer thread of the threaded rod, and the two thread sleeves are respectively meshed with the threads at both ends.

[0014] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0015] The assembled hanger for hoisting the precast steel skeleton of the T-beam is connected by setting the upper chord and the lower chord in a triangular structure through the truss, and the truss is also arranged in a triangular structure, so that the overall structural strength of a single hanger is good. At the same time, by setting that the upper chord and the lower chord are both formed by welding a pair of channel steels, and the shaft pin holes are reserved, it is convenient for on-site assembly of multiple groups of hangers, improving the applicability of the hanger. Since it can be quickly installed and disassembled, the corresponding transportation and storage costs are improved accordingly, and the practicability of the device is improved.

[0021] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0022] Please refer to Figures 1 to 4 , an assembled hanging bracket for hoisting the precast steel bar skeleton of a T-beam in this embodiment includes one upper chord 4 and two lower chords 2. A truss 3 is fixedly connected between the two lower chords 2 and the upper chord 4 for fixation.

[0023] Among them, the upper chord 4 and the two lower chords 2 are arranged in a triangular structure. The truss 3 is fixedly connected between the upper chord 4 and the lower chord 2 and between the two lower chords 2 respectively, so as to form a triangular stable structure.

[0024] Specifically, the truss 3 is continuously arranged in a V shape between the upper chord 4 and the lower chord 2.

[0025] With such a design, a planar triangular structure can also be formed between the trusses 3 before the upper chord 4 and the lower chord 2, ensuring the overall stability and structural strength of the hanging bracket.

[0026] It should be supplemented that the upper chord 4 and the two lower chords 2 are both formed by butt-welding a pair of channel steels. Therefore, both ends of the upper chord 4 and the lower chord 2 have pin holes 5 for assembling and connecting.

[0027] Preferably, a hanging structure 1 is provided on the upper chord 4. The hanging structure 1 includes a gantry crane hook and a steel wire rope for connection. A plurality of hanging structures 1 are evenly distributed on the upper chord 4 for evenly distributing the hanging load on the upper chord 4.

[0028] In this embodiment, there are several independent hanging brackets composed of the above-mentioned upper chord 4, lower chord 2 and truss 3. Adjacent hanging brackets are spliced through the penetration of a pin 6 and a pin hole 5.

[0029] It should be noted that an extension ring 7 is integrally connected to the middle of the pin 6. The upper chord 4 or the lower chord 2 can be inserted into the pin 6 for limit by abutting against the extension ring 7.

[0030] Preferably, the cross-sections of the pin 6 and the pin hole 5 are both rectangular. With such a design, loosening of the pin 6 relative to the pin hole 5 after docking can be avoided.

[0031] In this embodiment, a threaded rod 8 extending to the outside of the extension ring 7 is rotatably installed in the extension ring 7, and a threaded sleeve 9 located in the inner cavity of the pin 6 is threadedly connected to the outside of the threaded rod 8.

[0032] Furthermore, an extension rod 10 is fixedly installed on the outside of the threaded sleeve 9. A connecting rod 11 is rotatably installed at the end of the extension rod 10. A pin 12 that penetrates and extends outside the axle pin 6 is rotatably installed at one end of the connecting rod 11 away from the extension rod 10. By extending the pin 12 outside the axle pin 6 and abutting against the axle pin hole 5, the connection stability between the axle pin 6 and the upper chord 4 or the lower chord 2 can be enhanced.

[0033] In this embodiment, two sections of threads with opposite directions are provided on the outside of the threaded rod 8. Two threaded sleeves 9 are threadedly connected to the outside of the threaded rod 8. The two threaded sleeves 9 are respectively meshed with the threads at both ends, so that the two threaded sleeves 9 can move in opposite directions.

[0034] The working principle of the above embodiment is as follows:

[0035] Select the upper chord 4 and the lower chord 2 with appropriate lengths on-site as a single set of hanging brackets. Select appropriate hanging brackets for multiple extended ends of the precast T-beam steel bar skeleton, and then combine the hanging brackets to splice and adapt the overall hanging bracket structure on-site. By corresponding the positions of the opposite upper chord 4 and lower chord 2 in the two hanging brackets, use the axle pin 6 to respectively plug into the axle pin holes 5 on both sides of the hanging brackets, and clamp and rotate the end of the threaded rod 8 extending outside the outer extension ring 7. Through the threaded cooperation between the threaded rod 8 and the threaded sleeve 9, the threaded sleeve 9 moves relative to the threaded rod 8. At this time, the extension rod 10 and the connecting rod 11 connected to the threaded sleeve 9 move and push the pin 12 to extend outwards and abut against the axle pin hole 5 for fastening.
