Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, and in particular to an arched frame positioning device. Background Technology

[0002] In the field of slope protection engineering, arched frame structures are widely used to prevent slope collapse and soil erosion due to their excellent stability and protective performance. However, in the current construction process of arched frames, the control of linear positioning has always been a key problem affecting construction quality and efficiency.

[0003] Currently, there are two main construction methods in the industry: one is the multi-point rope control method, which uses multiple ropes laid out in the construction area to simulate the shape of the arch frame, serving as a reference for the placement and installation of precast blocks. However, due to the elasticity of the ropes themselves, they are easily deformed by external environmental factors (such as wind force and contact with construction personnel) during construction, making it difficult to guarantee the accuracy of the shape. This leads to deviations in the installation position of the precast blocks, affecting the stability and aesthetics of the overall structure. The second method relies on the experience of construction personnel. Based on the structural form of the arch frame precast blocks, construction personnel place and install them according to subjective judgment. This method is greatly affected by differences in the technical level and experience of the personnel, which not only fails to form a unified and standardized construction specification, but also results in a large fluctuation range in installation accuracy, making it difficult to meet the quality requirements of high-standard slope protection projects.

[0004] Whether using multi-point hanging rope control or experience-based installation, a large amount of manual adjustment and calibration work is required. Especially under complex slope terrain conditions, repeated adjustments will significantly increase construction time and extend the project cycle. At the same time, traditional methods lack reliable temporary support structures. If a deviation in alignment occurs during the installation of precast blocks, the installed precast blocks need to be removed and re-installed, which not only wastes materials but also further increases construction costs.

[0005] Therefore, it is necessary to provide a new arched frame positioning device to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides an arched frame positioning device.

[0007] The arched frame positioning device provided by this utility model includes a positioning column and a thin steel plate. Two sets of symmetrically distributed I-beam wheels are fixedly sleeved on the positioning column, and each I-beam wheel is equipped with multiple rotating rods that are distributed in a ring and rotatably connected. Each of the rotating rods is equipped with a support arm assembly, and the positioning column expands the thin steel plate through the support arm assembly on the I-beam wheel, driving the thin steel plate to form an arched frame structure.

[0008] Preferably, the support arm assembly includes a sleeve plate, one end of which is fixedly connected to the rotating rod, and a sliding plate is inserted inside the sleeve plate. The other end of the sliding plate extends out of the sleeve plate and is fixedly installed with a collar A.

[0009] Preferably, threaded fastening screws are installed on the side wall of the sleeve near the opening.

[0010] Preferably, the inner wall of the thin steel plate is fixedly installed with a plurality of collars B distributed at equal intervals.

[0011] Preferably, the collar A and the corresponding collar B are coaxially arranged vertically, and the collar A and collar B are fixedly connected by bolts.

[0012] Preferably, the top of each of the rotating rods passes through the wheel surface of the I-beam and is fixedly mounted with a screw, and the screw is fitted with a threaded nut.

[0013] Preferably, an anchor rod is fixedly installed at the bottom of the positioning post.

[0014] Compared with related technologies, the arched frame positioning device provided by this utility model has the following advantages: 1. This utility model uses positioning columns as the core support, combined with two sets of symmetrically distributed I-beam wheels. Multiple ring-shaped rotating rods are installed on the I-beam wheels. The rotating rods are connected to the support arm assembly.

It can provide a precise and stable linear reference for the installation of the arched frame prefabricated blocks, greatly reducing the installation position deviation of the prefabricated blocks and ensuring the consistency and stability of the overall structure. 2. This utility model can flexibly change the overall length of the support arm assembly by adjusting the length of the sliding plate extending out of the sleeve plate and fixing it with fastening screws, thereby adapting to the construction needs of arched frames with different radius specifications. 3. In this utility model, the thin steel plate is quickly and stably connected to the support arm assembly through the cooperation of collar A, collar B and bolts, which simplifies the installation process, reduces the operation difficulty for construction personnel, and helps to improve construction efficiency.

[0017] 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. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] Please see Figures 1 to 6 The present invention provides an arched frame positioning device, which includes a positioning column 1, an I-beam wheel 2, a support arm assembly 3, and a thin steel plate 4.

[0020] In the embodiments of this utility model, please refer to Figures 1 to 6 An anchor rod 11 is fixedly installed at the bottom of the positioning column 1. Two sets of symmetrically distributed I-beam wheels 2 are fixedly sleeved on the positioning column 1. Each I-beam wheel 2 is equipped with multiple ring-distributed and rotatably connected rotating rods 21. Each rotating rod 21 is equipped with a support arm group 3. The positioning column 1 expands the thin steel plate 4 through the support arm group 3 on the I-beam wheel 2, driving the thin steel plate 4 to form an arched frame structure. The top of each rotating rod 21 passes through the wheel surface of the I-beam wheel 2 and is fixedly mounted with a screw 22, and a threaded nut 23 is fitted on the screw 22.

[0021] It should be noted that: the positioning column 1 uses the anchor rod 11 to extend into the slope to a depth of not less than 15cm to prevent it from shifting to the side due to its own weight. Then, the support arm assembly 3 on the I-beam wheel 2 is deflected to form an arc-shaped structure. After the rotation is completed, the nut 23 is tightened so that the nut 23 fixes the screw 22, thereby completing the positioning of the angle of the support arm assembly 3. Then, the support arm assembly 3 is connected to the thin steel plate 4, thereby driving the thin steel plate 4 to bend into an arched frame structure, so that it can provide temporary support when the arched frame prefabricated blocks are installed.

[0022] In this embodiment: for scenarios with extremely small curvature radius, a thin steel plate 4 with a relatively thin thickness (1.5mm) is selected to reduce the difficulty of bending and reduce the risk of plastic deformation; for scenarios with large curvature radius, a thin steel plate 4 with a relatively thick thickness (2.5mm) is selected to enhance rigidity and prevent sagging. At the same time, high-strength spring steel is used in the material selection of the thin steel plate 4 to improve its elastic recovery ability, ensure that it can still maintain a good shape after multiple bending, and improve the reuse rate.

[0023] In the embodiments of this utility model, please refer to Figures 1 to 6 The support arm assembly 3 includes a sleeve plate 31. One end of the sleeve plate 31 is fixedly connected to the rotating rod 21, and a sliding plate 32 is inserted into the sleeve plate 31. The other end of the sliding plate 32 extends out of the sleeve plate 31 and is fixedly installed with a collar A321. A threaded fastening screw 33 is installed on the side wall of the sleeve plate 31 near the opening. Multiple collars B41 are fixedly installed on the inner wall of the thin steel plate 4, which are distributed vertically and horizontally at equal intervals. The collar A321 and the corresponding collar B41 are coaxially arranged vertically, and the collar A321 and the collar B41 are fixedly connected by bolts 5.

[0024] It should be noted that: the length of the support arm assembly 3 is adjusted according to the required radius of the arch frame. Specifically, this is done by sliding the sliding plate 32 along the outer side of the sleeve plate 31. Once the lengths of the sleeve plate 31 and the sliding plate 32 meet the required radius of the arch frame, the fastening screws 33 are tightened to fix the sleeve plate 31 and the sliding plate 32. The thin steel plate 4 is then attached to the sliding plate 32, and the collar A321 is adjusted to be connected to the collar B41 on the inner side of the thin steel plate 4. Finally, the collar B41 on the thin steel plate 4 is fixed to the collar A321 in each support arm assembly 3, so that the thin steel plate 4 forms an arch frame structure (as shown in the attached diagram). Figure 1 (As shown).

[0025] It is worth noting that the positioning column 1, I-beam wheel 2, support arm assembly 3, and thin steel plate 4 in this application are all made of rigid materials, have high structural strength, are not easily damaged, and can be disassembled and recycled after the completion of a project, transported to the next construction site for reassembly and use, reducing material waste and lowering the equipment procurement cost of the project.

[0026] The working principle of the arched frame positioning device provided by this utility model is as follows: Using positioning column 1 as the core support, and in conjunction with two sets of symmetrically distributed I-beam wheels 2, multiple ring-shaped and rotatable rotating rods 21 are installed on the I-beam wheels 2. The rotating rods 21 are connected to the support arm assembly 3, which can stably expand the thin steel plate 4 to form an arched frame structure. Compared with traditional rope control, the thin steel plate 4 is rigid and not easily deformed, providing a precise and stable linear reference for the installation of the arched frame precast blocks, significantly reducing the installation position deviation of the precast blocks, and ensuring the consistency and stability of the overall structure. This is achieved by adjusting the length of the sliding plate 32 extending beyond the sleeve plate 31, and utilizing... The fastening screws 33 fix the overall length of the support arm assembly 3, which can be flexibly changed to adapt to the construction needs of arched frames with different radius specifications. At the same time, the rotating rod 21 can rotate on the I-beam wheel 2. By adjusting the angle of the rotating rod 21 and fixing it with the screw 22 and nut 23, the shape of the arched frame can be further optimized to meet the diverse design requirements of slope protection projects. The thin steel plate 4 is quickly and firmly connected to the support arm assembly 3 through the cooperation of collar A321, collar B41 and bolt 5, which simplifies the installation process, reduces the operation difficulty of construction personnel, and helps to improve construction efficiency.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
