Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a steel structure support replacement device for vehicle ramp areas. Background Technology

[0002] In the process of urban construction, underground parking garages are an important part, providing indispensable parking spaces for urban residents. However, as the depth of the foundation pit increases during the construction of underground parking garages, the pressure on the side walls of the soil increases continuously, requiring the construction of temporary support devices to resist the pressure on the side walls of the foundation pit and prevent collapse accidents.

[0003] However, most of the existing temporary support devices for underground parking garages do not have additional adjustment margins for the fixing bolt holes. During construction, due to geological conditions and construction deviations, the pre-set fixing bolts are difficult to align precisely with the bolt holes. Since there is no adjustment space, the bolts cannot be inserted, which requires re-drilling, cutting steel pads, or replacing components to remedy the situation, thus affecting the construction progress and making it difficult to meet the needs of efficient construction of temporary support structures. Utility Model Content

[0004] The purpose of this application is to provide a steel structure replacement support device for automobile ramp areas, which has the advantages of facilitating fine-tuning of the steel structure. It solves the problem that most of the fixing bolt holes of existing foundation pit steel structures are circular. During construction, due to geological conditions and construction deviations, the circular fixing bolt holes cannot provide adjustment space, so it is necessary to re-drill holes, cut steel plates or replace components to remedy the situation, which affects the construction progress and makes it difficult to meet the needs of efficient construction of temporary support structures.

[0005] The steel structure support replacement device for the vehicle ramp area provided in this application adopts the following technical solution: The steel structure support replacement device for the vehicle ramp area includes two walls and steel pads. Multiple chemical bolts arranged in a rectangular array are fixedly connected to one side of each of the two walls. Multiple elliptical bolt holes arranged in a rectangular array are opened inside each of the two steel pads. Support plates are fixedly connected to the bottom of one side of each of the two steel pads. Positioning columns are fixedly connected to the upper ends of each of the two support plates. I-beams are fixedly connected to the upper ends of the two support plates.

[0006] By adopting the above technical solution, and through the use of chemical bolts and elliptical bolt holes, the position of the installed steel base plate can be adjusted. First, chemical bolts are driven into one side of each of the two walls to provide the basic connection points for the steel base plate. Elliptical bolt holes are then created inside the steel base plate. By sliding the chemical bolts within these holes, adjustment space is provided during installation, avoiding connection difficulties caused by construction errors. Subsequently, the I-beam is placed on the upper part of the support plate at the bottom of one side of the steel base plate, and the I-beam is positioned using two positioning posts on the upper part of the support plate. This ensures the I-beam is placed in the correct position during installation and prevents it from shifting due to vibration or other reasons during adjustment. When beam displacement occurs, chemical bolts are pre-inserted into one side of the wall during installation. Steel pads are then installed on the outer wall of the chemical bolts through the internal elliptical bolt holes. Subsequently, the I-beam is placed on the upper part of two support plates, with positioning holes limiting the position of the I-beam. The positions of the two steel pads are then adjusted according to installation requirements to ensure the horizontal installation of the I-beam. The I-beam at the upper part of the support plates acts as a load-bearing component, evenly transferring the load to the support plates and the wall. At the same time, because chemical bolts are used, the holes after removing the chemical bolts are easy to repair, causing less damage to the car ramp area. It can stably bear the load of the car ramp area, achieving an efficient and stable support replacement effect and meeting the usage requirements of the car ramp area.

[0007] Preferably, the bottom end of the I-beam has four positioning holes arranged in a rectangular array, and the bottom end of each of the four positioning holes is chamfered.

[0008] By adopting the above technical solution, four positioning holes arranged in a rectangular array are set at the bottom of the I-beam, and a chamfer is set at the bottom of each positioning hole. During installation, the positioning holes can provide a positioning reference for the I-beam, ensuring the accuracy of the I-beam installation. The chamfer at the bottom of the positioning holes can play a guiding role, avoiding jamming or misalignment of the connectors during insertion due to positional deviation. This simplifies the installation operation process and reduces the installation difficulty.

[0009] Preferably, the plurality of chemical bolts are slidably disposed inside the elliptical bolt holes.

[0010] By adopting the above technical solution, multiple chemical bolts are slidably placed inside the elliptical bolt holes. During the fine-tuning process after installation, the elliptical bolt holes can provide a certain amount of room for the chemical bolts to move. When it is necessary to adjust the position of the steel pad, the chemical bolts can slide inside the elliptical bolt holes without having to disassemble or drill again, thus simplifying the installation and adjustment process.

[0011] Preferably, all of the chemical bolts are provided through elliptical bolt holes, and a washer is fitted on the outer wall of one end of each chemical bolt that passes through the elliptical bolt hole. A nut is threaded onto the outer wall of the end of each chemical bolt that is away from the wall.

[0012] By adopting the above technical solution, the use of elliptical bolt holes, chemical bolts, washers, and nuts enables stable installation of the steel pad. During installation, the chemical bolt extends from one side of the wall and passes through the elliptical bolt hole on the steel pad. The elliptical bolt hole allows for fine-tuning of the chemical bolt within a certain range, addressing minor deviations that may occur during installation and facilitating easier alignment between the steel pad and the wall. After the chemical bolt passes through the elliptical bolt hole, a washer is placed on the outer wall, and then the nut is threaded onto the end of the chemical bolt furthest from the wall and tightened. The steel pad is fixed by the washer. The washer increases the contact area between the nut and the steel pad, preventing localized compression damage to the steel pad when the nut is tightened. This fixes the steel pad to one side of the wall, preventing it from loosening or shifting when the device is under load, thus improving the stability of the connection between the steel pad and the wall.

[0013] Preferably, each of the two support plates has four reinforcing ribs fixedly connected to its bottom end in a linear array, and the ends of the multiple reinforcing ribs away from the support plates are fixedly connected to the steel pad.

[0014] By adopting the above technical solution, four reinforcing ribs arranged in a straight line are fixedly connected to the bottom ends of the two support plates. During use, when the support plates are subjected to external forces or loads transmitted by the I-beams, the reinforcing ribs can disperse the pressure and prevent the pressure from concentrating at the connection between the support plates and the steel pads. This prevents the support plates from deforming or being damaged due to excessive force, further improving the load-bearing capacity and deformation resistance of the entire structure. It ensures that the structure can stably bear the load during use and enhances the durability and reliability of the overall structure.

[0015] Preferably, both upper ends of the two steel pads are fixedly connected with lifting lugs.

[0016] By adopting the above technical solution, and by fixing lifting lugs to the upper ends of both sides of the two steel pads, the lifting lugs can serve as load-bearing fulcrums when installing or adjusting the position of the steel pads. This facilitates the connection between the steel pads and the lifting tools, making the lifting and adjustment of the steel pads more stable and controllable. It ensures that the steel pads can be accurately aligned and installed, improves the convenience and efficiency of the steel pad installation operation, guarantees the safety during the construction process, and reduces structural damage caused by improper handling.

[0017] Preferably, all four positioning posts are slidably disposed inside the positioning holes.

[0018] By adopting the above technical solution, and by sliding the four positioning columns inside the positioning holes, during the installation of the I-beam, it is only necessary to align the positioning holes at the bottom of the I-beam with the positioning columns at the top of the support plate. The initial alignment of the I-beam can be completed quickly without repeated fine calibration, reducing the operational difficulty during installation and making the assembly process more efficient. At the same time, after the I-beam is initially positioned, the sliding fit of the positioning columns in the positioning holes can also constrain the I-beam to a certain extent, limiting its horizontal displacement. This ensures that the I-beam can maintain a stable installation position during subsequent fine adjustments, avoiding the impact of positional displacement on the overall force balance of the device.

[0019] Preferably, both ends of the I-beam are fixedly connected to steel pads.

[0020] By adopting the above technical solution, the two ends of the I-beam are fixedly connected to the steel base plate by welding, so that the I-beam and the steel base plate form a tight whole, which enhances the connection strength between the I-beam and the steel base plate. During the entire structural stress process, the load borne by the I-beam can be transferred to the steel base plate, which improves the load-bearing capacity of the steel structure and ensures safety during use.

[0021] In summary, this application includes the following beneficial technical effects: This steel structure support device for the car ramp area utilizes chemical bolts installed on one side of the wall to mate with elliptical bolt holes on a steel pad. The chemical bolts provide the basic connection points, while the elliptical bolt holes offer adjustment space for the steel pad installation, resolving connection difficulties caused by construction errors. An I-beam is placed on the support plate, and its position is restricted by positioning holes and posts. Then, using lifting lugs and a hoisting device, the steel pad is fine-tuned to ensure the I-beam is level. Washers and nuts are used to fix the position of the steel pad, ensuring a stable connection to the wall. Simultaneously, the reinforcing ribs at the bottom of the support plate distribute the load and prevent deformation. Finally, both ends of the I-beam are welded to the steel pad, forming a tight, integrated structure. This allows the I-beam to evenly distribute the load to the wall, ensuring the load-bearing requirements of the steel structure. The use of chemical bolts for connection results in smaller holes after removal, facilitating repairs and minimizing damage to the ramp, thus ensuring the structural safety of the car ramp area.

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0025] Example 1: Steel structure support replacement device for automobile ramp area, refer to Figure 1 , Figure 2 and Figure 3 The system includes two walls 1 and steel pads 3. Multiple chemical bolts 2 arranged in a rectangular array are fixedly connected to one side of each wall 1, providing basic connection points for the steel pads 3. Multiple elliptical bolt holes 4 arranged in a rectangular array are opened inside each steel pad 3. By sliding the chemical bolts 2 into the elliptical bolt holes 4, adjustment space can be provided during installation, avoiding connection difficulties caused by construction errors. Support plates 5 are fixedly connected to the bottom of one side of each steel pad 3, and positioning posts 6 are fixedly connected to the top of each support plate 5. I-beams 7 are fixedly connected to the top of each support plate 5. The I-beams 7 are placed on the top of the support plates 5 at the bottom of one side of the steel pad 3, and positioned by the two positioning posts 6 on the top of the support plates 5, ensuring that the I-beams 7 are placed in the correct position during installation and preventing displacement of the I-beams 7 due to vibration or other reasons during adjustment.

[0026] Example 2: Steel structure support replacement device for automobile ramp area, refer to Figure 1 , Figure 4 and Figure 5The bottom end of the I-beam 7 has four positioning holes 8 arranged in a rectangular array. Each of the four positioning holes 8 has a chamfer 9 at its bottom. By providing a positioning reference for the I-beam 7 during installation, the positioning holes 8 ensure accurate installation. The chamfer 9 at the bottom of the positioning holes 8 acts as a guide, preventing jamming or misalignment of the connectors during insertion due to positional deviations. This simplifies the installation process and reduces installation difficulty. Multiple chemical bolts 2 are slidably positioned inside elliptical bolt holes 4. This allows for some movement of the chemical bolts 2 during fine-tuning after installation. When the position of the steel pad 3 needs adjustment, the chemical bolts 2 can slide within the elliptical bolt holes 4 without needing to disassemble or drill again, simplifying the installation and adjustment process. All chemical bolts 2 penetrate the elliptical bolt holes 4. Each of the circular bolt holes 4 has a washer 10 fitted on one end of its outer wall. Nuts 11 are threaded onto the outer walls of the multiple chemical bolts 2 at their ends away from the wall 1. The arrangement of the elliptical bolt holes 4, chemical bolts 2, washer 10, and nuts 11 ensures stable installation of the steel pad 3. During installation, the chemical bolts 2 extend from one side of the wall 1 and pass through the elliptical bolt holes 4 on the steel pad 3. These elliptical bolt holes allow for fine-tuning of the chemical bolts 2 within a certain range, addressing minor deviations that may occur during installation and ensuring proper alignment between the steel pad 3 and the wall 1. For easier alignment, after the chemical bolt 2 passes through the elliptical bolt hole 4, a washer 10 is fitted on the outer wall, and then the nut 11 is threaded to the end of the chemical bolt 2 away from the wall 1 and tightened. The steel pad 3 is fixed by the pressure plate. The setting of the washer 10 can increase the contact area between the nut 11 and the steel pad 3, and avoid local squeezing damage to the steel pad 3 when the nut 11 is tightened. The steel pad 3 is fixed to one side of the wall 1 to prevent the steel pad 3 from loosening or shifting when the device is under load, and improves the stability of the connection between the steel pad 3 and the wall 1.

[0027] Reference Figure 3 , Figure 5 and Figure 6Each of the two support plates 5 has four reinforcing ribs 12 fixedly connected to its bottom end in a linear array. The ends of these reinforcing ribs 12 furthest from the support plate 5 are fixedly connected to the steel pad 3. By fixing four reinforcing ribs 12 in a linear array to the bottom ends of the two support plates 5, during use, when the support plate 5 bears the external force or load transmitted by the I-beam 7, the reinforcing ribs 12 can disperse the pressure, preventing pressure concentration at the connection between the support plate 5 and the steel pad 3. This prevents the support plate 5 from deforming or being damaged due to excessive force, further improving the load-bearing capacity and deformation resistance of the entire structure. To ensure stable load bearing during use and enhance the durability and reliability of the overall structure, lifting lugs 13 are fixedly connected to the upper ends of both sides of the two steel pads 3. By fixing the lifting lugs 13 to the upper ends of both sides of the two steel pads 3, the lifting lugs 13 can serve as load-bearing fulcrums when installing or adjusting the position of the steel pads 3. This facilitates connection with lifting tools, making the lifting and adjustment of the steel pads 3 more stable and controllable, ensuring accurate alignment and installation, improving the convenience and efficiency of the installation operation, guaranteeing safety during construction, and reducing the risk of damage caused by handling. Improper installation can lead to structural damage. All four positioning posts 6 are slidably installed inside the positioning holes 8. By sliding the four positioning posts 6 inside the positioning holes 8, during the installation of the I-beam 7, it is only necessary to align the positioning hole 8 at the bottom of the I-beam 7 with the positioning post 6 at the top of the support plate 5. This allows for quick initial alignment of the I-beam 7 without repeated fine calibration, reducing the difficulty of installation and making the assembly process more efficient. Furthermore, after the I-beam 7 is initially positioned, the sliding fit of the positioning posts 6 within the positioning holes 8 can also provide a certain constraint on the I-beam 7, limiting its horizontal movement. The offset ensures that the I-beam 7 maintains a stable installation position during subsequent fine-tuning, preventing the positional deviation from affecting the overall stress balance of the device. Both ends of the I-beam 7 are fixedly connected to the steel pad 3. By welding the two ends of the I-beam 7 to the steel pad 3 respectively, the I-beam 7 and the steel pad 3 form a tight whole, enhancing the connection strength between the I-beam 7 and the steel pad 3. During the entire structural stress process, the load borne by the I-beam 7 can be transferred to the steel pad 3, improving the load-bearing capacity of the steel structure and ensuring safety during use.

[0028] The implementation principle of this application embodiment is as follows: First, chemical bolts 2 are fixed on one side of the two walls 1 at the installation location to provide a basic connection point for the installation of steel pad 3. At the same time, using the elliptical bolt holes 4 inside the steel pad 3, the steel pad 3 is fitted onto the outer wall of the chemical bolt 2 through the elliptical bolt holes 4. The elliptical bolt holes 4 allow the chemical bolt 2 to slide in the hole, providing space for the position adjustment of the steel pad 3, which is convenient to deal with possible installation deviations during construction and achieves the initial alignment of the steel pad 3 with the wall 1. Then, the I-beam 7 is placed on the upper end of the support plate 5 at the bottom of one side of the wall 1, so that the positioning post 6 at the upper end of the support plate 5 is inserted into the positioning hole 8 at the bottom end of the I-beam 7. The chamfer 9 at the bottom end of the positioning hole 8 can guide the positioning post 6 to be inserted smoothly, and the initial positioning of the I-beam 7 can be quickly completed without repeated calibration. At the same time, the sliding fit between the positioning post 6 and the positioning hole 8 can limit the horizontal displacement of the I-beam 7 and ensure that it maintains a stable position during subsequent fine-tuning operations. Subsequently, using the lifting lugs 13 on both sides of the upper end of the steel pad 3, the steel pad 3 is moved by the lifting tools and its position is adjusted to a suitable state to ensure that the I-beam 7 remains horizontal. A washer 10 is placed on the outer wall of the end of the chemical bolt 2 that passes through the elliptical bolt hole 4. Then, the nut 11 is threaded to the end of the chemical bolt 2 away from the wall 1 and tightened. The washer 10 increases the contact area between the nut 11 and the steel pad 3, preventing damage to the steel pad 3 and firmly fixing the steel pad 3 to one side of the wall 1 to prevent the steel pad 3 from loosening or shifting during subsequent use. The two ends of the I-beam 7 are welded to the steel pad 3 to form a tight whole, thus completing the installation of the structure. After the steel structure is disassembled, the holes after removing the chemical bolts 2 are easy to repair due to the use of chemical bolts 2, resulting in less damage to the car ramp area. It can stably bear the load of the car ramp area, achieving an efficient and stable support replacement effect and meeting the usage requirements of the car ramp area.
