Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a steel reinforcement formwork frame for building engineering. Background Technology

[0002] In the field of construction engineering, reinforced concrete structures are widely used in the construction of various infrastructure projects such as high-rise buildings, bridges, tunnels, and water conservancy facilities due to their high strength, durability, and excellent seismic performance. As the skeleton of the concrete structure, the correct arrangement and secure binding of the reinforcing steel bars directly affect the quality and safety of the entire project.

[0003] Current rebar tying work relies on manual operation by workers, using wire or specialized tying tools to tightly connect intersecting rebars. To ensure the accuracy of rebar spacing and position, rebar formwork frames are often used as auxiliary tools during construction. A rebar formwork frame is a pre-fabricated frame structure based on design drawings, equipped with positioning posts or plates to temporarily fix the rebars, maintaining their predetermined positions and spacing, facilitating quick and accurate tying operations. However, after the rebar tying is completed, existing rebar formwork frames require manual removal of the positioning posts or devices fixing the rebars one by one. This is not only time-consuming and labor-intensive, increasing the workers' workload, but also, because the removal and reinstallation of positioning posts is repetitive work, it is prone to inaccurate positioning due to improper operation, affecting the quality and efficiency of subsequent rebar tying.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a steel reinforcement formwork frame for construction engineering.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] As further explained, the unloading component includes a lower seat, an upper seat, and two sets of opposing sliders; the upper seat and the lower seat are symmetrically distributed on the positioning column, and each of the upper seat and the lower seat is provided with a sliding seat, and each sliding seat is provided with an inclined slide rail at both ends; the two sets of sliders are respectively movably mounted on the sliding seats, and each slider is provided with a slide groove that slides in connection with the slide rail; the slider has a triangular structure; a first adjusting screw is provided between the two sets of sliders; the end of the first adjusting screw passes through both sets of sliders at one time, and a first nut is threadedly connected to the end of the first adjusting screw.

[0012] As further explained, a second adjusting screw is provided between the upper seat and the lower seat; one end of the second adjusting screw is fixed to the upper seat, the other end passes through the lower seat, and a second nut is threadedly connected between the other end of the second adjusting screw and the lower seat.

All positioning blocks retract towards the inside of the positioning columns, forming sufficient detachment space, making it easy for workers to remove the tied rebar cage without completely disassembling the positioning blocks. This significantly shortens the operation time, reduces labor intensity, and avoids positioning deviation problems caused by repeated disassembly and assembly. Attached Figure Description

Therefore, they should not be construed as limitations on this application.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] In one embodiment of this utility model, such as Figure 1-6As shown, a rebar formwork frame for construction engineering is provided, including a base 10, positioning columns 20, hook frames 30, and side adjustment components 40. The base 10 is provided with a limiting plate 11 for placing the bottom rebar. Four sets of positioning columns 20 are circumferentially arranged on the base 10. Multiple sets of positioning blocks 21 for fixing the rebar are provided on the positioning columns 20. A connecting component for rotating the positioning blocks 21 is provided between the positioning blocks 21 and the positioning columns 20. Two sets of hook frames 30 are respectively straddled at the top of the two sets of positioning columns 20, and both ends of the hook frames 30 are fixedly connected to the top of the positioning columns 20. The two sets of hook frames 30 are arranged in parallel. A load-bearing component for adjusting the lifting and lowering of the hook frames 30 is provided between the hook frames 30 and the positioning columns 20. The side adjustment components 40 are located between the two sets of hook frames 30, and both ends of the side adjustment components 40 are fixedly connected to the positioning columns 20.

[0037] By setting a rotatable positioning block 21 on the positioning column 20 and cooperating with the key limiting shaft 24 in the connecting component to limit the position of the end of the positioning block 21, the positioning block 21 can be flexibly flipped. After the steel bar is tied, the unloading component is operated to move the hook frame 30 down, release the top steel bar from the fixation, and then the entire steel cage is pushed up by external force. At this time, the lower layer of steel bars will push the positioning block 21 on the upper layer to rotate around the rotating shaft 23 in the connecting component. All positioning blocks 21 are retracted towards the inside of the positioning column 20, forming sufficient separation space, which makes it easy for workers to take out the tied steel cage without completely disassembling the positioning block 21, greatly shortening the operation time, reducing labor intensity, and avoiding the positioning deviation problem caused by repeated disassembly and assembly.

[0038] Preferably, the positioning column 20 includes at least two sets of parallel-distributed upright plates 22, and the positioning block 21 is rotatably connected between the two sets of upright plates 22. By setting at least two sets of upright plates 22, the bending resistance of the positioning column 20 is improved, the positioning block 21 remains stable when subjected to the impact of steel bar binding, and the risk of positioning deviation caused by column deformation is eliminated.

[0039] Furthermore, the connecting components include a rotating shaft 23 and a limiting shaft 24. The rotating shaft 23 is located between the upright plate 22 and the positioning block 21, and the positioning block 21 is rotatably connected to the rotating shaft 23. The limiting shaft 24 is located above the rotating shaft 23 and abuts against the end of the positioning block 21. The limiting shaft 24 is fixedly connected to the upright plate 22. The end of the positioning block 21 away from the positioning column 20 is provided with a bearing portion 21a for placing the reinforcing bar. The end of the positioning block 21 near the positioning column 20 is provided with a limiting portion 21b for limiting the position.

[0040] By setting a rotating shaft 23, the positioning block 21 can rotate at a certain angle between the two upright plates 22 of the positioning column 20, so as to form a space for the rebar cage to be removed. Furthermore, by setting a limiting shaft 24, the rotation stroke of the positioning block 21 is limited. That is, when the rebar is under load, the limiting shaft 24 and the end of the positioning block 21 form a stable support to prevent accidental deflection. During adjustment, only a certain external force needs to be applied to make the positioning block 21 rotate and retract, thus realizing precise mechanical control of the positioning block 21. By replacing manual fixing operation with the design of connecting components, the positioning efficiency is significantly improved, while avoiding the loosening or inaccurate positioning problems that may be caused by manual operation.

[0041] Preferably, the unloading component includes a lower seat 31, an upper seat 32, and two sets of opposing sliders 33. The upper seat 32 and the lower seat 31 are symmetrically distributed on the positioning column 20. Both the upper seat 32 and the lower seat 31 are provided with sliding seats 34, and both ends of the sliding seats 34 are provided with inclined slide rails. The two sets of sliders 33 are respectively movably mounted on the sliding seats 34, and the sliders 33 are provided with slide grooves that slide with the slide rails. The sliders 33 have a triangular structure. A first adjusting screw 35 is provided between the two sets of sliders 33. The end of the first adjusting screw 35 passes through both sets of sliders 33 at one time, and the end of the first adjusting screw 35 is threadedly connected to a first nut 351. By setting the first adjusting screw 35 and the first nut 351, when unloading, the operator only needs to unscrew the first nut 351 outwards. Under the weight of the hook frame 30, the upper seat 32 and the lower seat 31 move closer to each other, causing the two sets of sliders 33 to move outwards along their corresponding slide rails, thus realizing the downward movement of the hook frame 30. Conversely, by tightening the first nut 351 inwards, the upper seat 32 and the lower seat 31 move away from each other, thus realizing the upward movement of the hook frame 30. This achieves the lifting and lowering adjustment of the hook frame 30, simplifying the height adjustment steps of the hook frame 30.

[0042] Furthermore, a second adjusting screw 36 is provided between the upper seat 32 and the lower seat 31. One end of the second adjusting screw 36 is fixed to the upper seat 32, and the other end passes through the lower seat 31. A second nut 361 is threadedly connected between the other end of the second adjusting screw 36 and the lower seat 31. By setting the second adjusting screw 36 and the second nut 361, the upper seat 32 and the lower seat 31 are formed into a whole under the action of the threaded connection between the second nut and the second adjusting screw 36. This facilitates the installation of the two sets of sliders between the upper seat 32 and the lower seat 31, reduces the assembly time of the entire unloading device, and improves the assembly efficiency.

[0043] Furthermore, at least one set of height-adjustable columns 25 is provided between the unloading component and the positioning column 20. By setting at least one set of height-adjustable columns 25, the number of height-adjustable columns 25 can be adjusted according to the actual working conditions, and the height of the hook frame 30 can be flexibly adjusted to meet the needs of diverse construction scenarios.

[0044] Preferably, the hook frame 30 is provided with multiple sets of hooks 37 for hanging reinforcing bars. In this embodiment, the multiple sets of hooks 37 can be hooks 37 of different lengths or hooks 37 of equal length; the specific choice depends on the actual working conditions and is not specifically limited. By setting the hooks 37, it is convenient to hang the top reinforcing bars. At the same time, since one side of the hook 37 has an open structure, it is also convenient to remove the reinforcing bars after they are tied, simplifying the steps for removing the reinforcing bar cage, effectively shortening the removal time of the reinforcing bar cage, and improving work efficiency.

[0045] Preferably, the side adjustment component 40 includes a fixed rod 41 and an adjustment plate 42. The fixed rod 41 is fixedly connected at both ends to two adjacent sets of positioning columns 20. The adjustment plate 42 is rotatably connected to one side of the fixed rod 41, such as by a hinge. The adjustment plate 42 is provided with multiple sets of limiting grooves 421 for limiting the position of the side reinforcement bars. The adjustment plate 42 is also provided with a handrail 422. In this embodiment, the position of the limiting grooves 421 on the adjustment plate 42 needs to be determined according to the actual position of the side reinforcement bars in the steel cage, and there are no specific restrictions. By setting the limiting grooves 421, the position of the side reinforcement bars is limited, simplifying the positioning steps of the side reinforcement bars, thereby shortening the binding time of the reinforcement bars and improving work efficiency.

[0046] Preferably, a reinforcing column 12 is provided between the positioning column 20 and the base 10. Multiple sets of climbing ramps 13 are provided on the reinforcing column 12 for workers to climb. By providing the reinforcing column 12, a stable triangular structure is formed between the reinforcing column 12, the positioning plate 22, and the base 10, improving the overall support strength of the steel reinforcement formwork frame. Simultaneously, the climbing ramps 13 facilitate workers moving to the top of the steel reinforcement formwork frame to secure the top steel bars.

[0047] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
