Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a lifting support frame for tying beam reinforcement and an auxiliary tool for tying beam reinforcement. Background Technology

[0002] Currently, there are generally two methods for tying beam reinforcement: One method involves tying the beam reinforcement directly in its original position after the beam and slab formwork is laid. However, due to space constraints, workers often cannot perform tying work on the bottom two rows of reinforcement, the side reinforcement, or correcting any missing stirrups, leading to potential quality issues. The other method uses timber or steel pipes to support the bottom reinforcement of the beam, elevating the reinforcement cage. Temporary steel pipe supports are then erected on both sides of the reinforcement, allowing workers to tie the reinforcement above the beam in its original position. However, this method poses significant safety risks because the temporary supports are unstable, the load-bearing capacity of the timber and steel pipes cannot be guaranteed, and the reinforcement cage needs to be lowered back to its original position using a tower crane after tying. The weight of the reinforcement cage is unpredictable and may exceed the tower crane's lifting limit.

[0003] Utility model patent CN208686109U discloses a lifting beam rebar tying support frame, comprising two vertically arranged parallel main poles that can be raised and lowered. Each main pole has a corner bar connected to its lifting top, and the other end of the corner bar extends to the bottom of the main pole and is connected to a crossbar. The crossbar connecting the two main poles can be assembled into a single load-bearing crossbar. This lifting beam rebar tying support frame facilitates beam rebar tying construction and allows the beam rebar to be placed back into its original position. The utility model also discloses a beam rebar tying auxiliary tool comprising multiple sets of the aforementioned lifting beam rebar tying support frames, with all load-bearing crossbars arranged horizontally in parallel. This beam rebar tying auxiliary tool can improve the efficiency of beam rebar tying. However, the aforementioned prior art suffers from poor stability and difficulty in lifting beam rebar.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the beam reinforcement binding and lifting support frame in this embodiment includes two pairs of diagonal braces 1 arranged at the front and rear, and a crossbar arranged between the two pairs of diagonal braces 1. The two pairs of diagonal braces 1 are arranged at an incline and symmetrically, and their upper ends are connected. The crossbar is connected to the upper ends of the two pairs of diagonal braces 1, and both ends of the crossbar are equipped with lifting mechanisms, which are used to drive the beam reinforcement to rise and fall.

[0027] In this embodiment, the two ends of the crossbar are provided with rotating shafts 2, and the upper end of the diagonal brace 1 is fixedly provided with an upper ear plate 3. The rotating shaft 2 passes through the upper ear plate 3 and is rotatably connected to the upper ear plate 3. The upper ear plate 3 is provided with a locking mechanism to restrict rotation. The lower end of the diagonal brace 1 is provided with a base plate 4, and the lower end of the diagonal brace 1 is hinged to the base plate 4.

[0028] Specifically, in combination Figure 4 and Figure 5As shown, between the two upper ear plates 3 at the upper ends of the two paired diagonal braces 1, the upper ear plate 3 closer to the crossbar has multiple limiting holes 5 arranged in a circular array around the rotation axis 2. The upper ear plate 3 further away from the crossbar has a through hole, which selectively corresponds to the corresponding limiting hole 5. The locking mechanism includes a rod, a baffle 6, and a spring 7. One end of the rod passes through the through hole and the limiting hole 5 in sequence and is slidably connected to both upper ear plates 3. The baffle 6 is fixed to the other end of the rod. The spring 7 is sleeved on the rod, and both ends of the spring 7 are fixedly connected to the baffle 6 and the upper ear plate 3 further away from the crossbar, respectively. By pulling the limiting plate away from the crossbar, the rod is disengaged from the limiting hole 5, and the angle between the two diagonal braces 1 can be adjusted so that the other limiting hole 5 corresponds to the through hole. When the limiting plate is released, the rod is inserted into the limiting hole 5 under the action of the spring 7, thereby locking the angle between the two diagonal braces 1.

[0029] In this embodiment, the lifting mechanism includes a first connecting cable 8, fixed pulleys 11, a second connecting cable 12, a lifting platform 9, and a crane. An extension rod 10 is fixed to the end of the rotating shaft 2 furthest from the crossbar. The upper end of the first connecting cable 8 is connected to the extension rod 10. Two fixed pulleys 11 are installed on the upper parts of two paired diagonal braces 1, and these two fixed pulleys 11 are located between the paired diagonal braces 1. A second connecting cable 12 is wound around each of the two fixed pulleys 11. The two second connecting cables 12 are of the same length, and their upper ends are fixedly connected to the lower end of the first connecting cable 8. The end of the second connecting cable 12 furthest from the first connecting cable 8 passes around the side of the two fixed pulleys 11 furthest from each other and extends downwards to be fixedly connected to the top surface of the lifting platform 9. The crane is installed on the bottom surface of the lifting platform 9.

[0030] In this embodiment, the hoist includes a dual-head motor 13, a take-up roller 14, and lifting cables 15. The dual-head motor 13 is horizontally fixed to the bottom surface of the hoisting platform 9. The output shaft of the dual-head motor 13 is perpendicular to the length direction of the crossbar, and the output shafts at both ends of the dual-head motor 13 are connected to the take-up roller 14. The two lifting cables 15 are respectively wound around the take-up roller 14, and a hook 16 is connected to one end of the cable that is free from the take-up roller 14. The arrangement of the dual take-up roller 14, lifting cables 15, and hooks 16 increases the number of lifting points for the beam reinforcement, thereby enhancing the stability of the hoisted beam reinforcement.

[0031] In this embodiment, the base plate 4 at the lower end of each diagonal brace 1 is independently set. A lower telescopic rod 17 is set between two base plates 4 on the same side. By extending and shortening the lower telescopic rod 17, the distance between the two pairs of diagonal braces 1 is adjusted, thereby adjusting the distance between the two cranes. Specifically, a lower connecting plate 25 is set between two base plates 4 on the same side of the crossbar. The lower telescopic rod 17 is embedded in the side of the base plate 4 near the lower connecting plate 25. The lower telescopic rod 17 can be an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder. The extended end of the lower telescopic rod 17 extends out of the outside of the base plate 4 and is connected to the lower connecting plate 25.

[0032] The crossbar includes an upper connecting plate 18 and upper telescopic rods 19. The upper connecting plate 18 is positioned between two rotating shafts 2, and the two upper telescopic rods 19 are installed on both sides of the upper connecting plate 18. One end of each upper telescopic rod 19 is connected to the upper connecting plate 18, and the other end is connected to the rotating shaft 2. The upper telescopic rod 19 can be an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder. Thus, by simultaneously adjusting the upper telescopic rod 19 and the lower telescopic rod 17, the distance between the two lifting mechanisms can be adjusted.

[0033] In this embodiment, for ease of movement, a mounting plate 20 is provided on the top edge of the base plate 4. The mounting plate 20 has a "7"-shaped structure, and a bottom telescopic rod 21 is vertically provided on the top surface of the mounting plate 20. The protruding end of the bottom telescopic rod 21 passes through the top surface of the mounting plate 20 and is connected to a caster wheel 22. Specifically, the bottom telescopic rod 21 can be an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder. By extending the bottom telescopic rod 21, the caster wheel 22 moves downward to contact the support position below the base plate 4, causing the base plate 4 to disengage from the support position below the base plate 4, thereby facilitating movement. When using the support frame in this embodiment to lift the reinforcing beam, the bottom telescopic rod 21 shortens, allowing the base plate 4 to resume its supporting function, and the caster wheel 22 moves upward to disengage from the support position below the base plate 4, ensuring that the support frame is in a stable state when lifting the reinforcing beam.

[0034] Preferably, the base plate 4 has a rectangular structure, and two mounting plates 20 are respectively provided on the top surface of the base plate 4 and the two sides adjacent to the lower telescopic rod 17, so that four universal wheels 22 are provided on the edge of the base plate 4.

[0035] In this embodiment, a pull ring 23 is fixed to the bottom of the outer side of the diagonal brace 1. Preferably, the pull ring 23 is located in the middle of the diagonal brace 1, and a cable 24 is detachably connected between each pair of pull rings 23. The two cables 24 are arranged in a cross configuration. When using this support frame, the cable 24 is installed after the crossbar is adjusted to a suitable height. The function of the cable 24 is that when the crane lifts the beam reinforcement, the beam reinforcement will generate a downward tension on the lifting cable 15. The tension will be transmitted to the crossbar and the diagonal brace 1, generating a downward tension on the diagonal brace 1. Since the diagonal brace 1 is inclined, the two pairs of diagonal braces 1 are subjected to forces in opposite directions to the horizontal. By setting the cable 24, the cable 24 will generate an inward tension on the diagonal brace 1, thereby further ensuring the stability of the support frame.

[0036] This embodiment also provides an auxiliary tool for tying beam reinforcement, which includes multiple sets of the above-mentioned beam reinforcement tying lifting support frames. The multiple sets of beam reinforcement tying lifting support frames are arranged sequentially along the length direction of the beam reinforcement, which facilitates the hoisting of the entire beam reinforcement and the tying and lowering of the entire beam reinforcement.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
