Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a bridge support device. Background Technology

[0002] The foundation anchoring of steel pipes typically refers to the method by which a steel pipe forms a stable connection with the foundation (such as concrete, rock, or soil). This process usually involves methods such as pre-embedding, anchoring, welding, bolting, and grouting, making the steel pipe an integral part of the foundation structure, serving a supporting, force-transferring, or fixing function. There are two common anchoring methods: one is the friction pile method, where the required embedment depth is calculated based on the design, and the steel pipe is used as a friction pile, directly inserted into the ground to generate sufficient friction between the steel pipe and the soil, thereby achieving force transfer; the other is the concrete foundation pre-embedding method, where pre-embedded parts and steel plates are installed during the concrete foundation pouring process and anchored to the top surface of the concrete. After the concrete has cured, the steel pipe and the pre-embedded steel plate are then welded together.

[0003] When the pipeline network in the construction area is complex, making it impossible to directly insert steel pipes into the ground, and the construction period is tight, prefabricated steel pipe supports can be used to reduce the splicing time of the supports and improve construction efficiency. However, these steel pipe supports have extremely high requirements for the accuracy of the position, angle, and spacing of the embedded parts, and the disassembly of the supports after construction is relatively complicated and difficult to remove completely. This not only affects construction efficiency but may also lead to material waste and increase the overall construction cost.

[0004] Therefore, there is an urgent need for a bridge support device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a bridge support device that can ensure the pre-embedding accuracy of the pre-embedded components during concrete pouring and achieve rapid pre-embedding. It enables the rapid and intact assembly and disassembly of the prefabricated steel pipe support and the pre-embedded components, improves construction efficiency, reduces assembly costs, and makes the bridge support device firmly rooted, thereby meeting the construction requirements and tight schedule needs in complex underground pipeline environments.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Bridge support device, comprising:

[0008] At least two concrete foundation formwork assemblies are laid side by side adjacent to each other on the ground. Each concrete foundation formwork assembly includes a steel reinforcement skeleton and a support frame. The support frame contains the steel reinforcement skeleton for pouring concrete.

[0009] The positioning component includes at least four positioning elements and a connecting frame. The at least four positioning elements are all disposed on the connecting frame. Each positioning element has multiple positioning holes. The positioning component is detachably connected to at least two adjacent concrete foundation formwork components. When the positioning component is connected to at least two adjacent concrete foundation formwork components, each positioning hole is spatially aligned with the corresponding connection part of the prefabricated bracket.

[0010] The column base anchor bolt can be inserted into the positioning hole. The lower end of the column base anchor bolt is connected to the steel reinforcement cage, and the upper end of the column base anchor bolt extends beyond the upper surface of the positioning member and can be detachably connected to the prefabricated bracket.

[0011] Furthermore, the connecting frame includes at least four connecting rods forming a rectangle, and at least four positioning elements are respectively disposed at the four corners of the connecting frame.

[0012] Furthermore, the connecting frame is provided with reinforcing ribs.

[0013] Furthermore, the reinforcing ribs are arranged along the diagonal of the connecting frame.

[0014] Furthermore, the positioning component includes a positioning disk, on which at least four positioning holes are provided, and the at least four positioning holes are distributed at intervals around the central axis of the positioning disk.

[0015] Furthermore, the positioning disk is fixedly connected to the connecting frame.

[0016] Furthermore, the positioning disk is detachably connected to the connecting frame.

[0017] Furthermore, the positioning disc is detachably provided with a limiting element on the side facing away from the concrete foundation formwork assembly to limit the insertion depth of the column base anchor bolt.

[0018] Furthermore, the connecting frame is provided with a buckle, which engages with the supporting frame.

[0019] Furthermore, the prefabricated support includes a prefabricated support body and a prefabricated support base. The prefabricated support base is located at the end of the prefabricated support body facing the concrete. The column anchor bolt can pass through the prefabricated support base and is bolted to the prefabricated support base.

[0020] The beneficial effects of this utility model are:

[0021] This utility model provides a bridge support device, including at least two concrete foundation formwork components, a positioning component, column base anchors, and a prefabricated bracket. Construction workers can first lay the concrete foundation formwork components side-by-side at the intended placement location of the bridge support device, providing a foundation pouring location for the concrete structure of the bridge support device. By detachably connecting the positioning component across at least two adjacent concrete foundation formwork components, the assembly and disassembly of the positioning component becomes more efficient, allowing for reuse and convenient turnover. By setting the positioning component on the connecting frame and providing multiple positioning holes, when the positioning component is connected to at least two adjacent concrete foundation formwork components, each positioning hole spatially aligns with one of the prefabricated brackets. With the corresponding connection points aligned, the column base anchors can be inserted into the positioning holes for concrete pouring, ensuring the anchors are embedded in the concrete and guaranteeing the connection accuracy between the anchors and the prefabricated supports. The lower end of the anchors connects to the steel reinforcement skeleton of the concrete foundation formwork assembly, while the upper end extends beyond the upper surface of the positioning component and can be detachably connected to the prefabricated supports. This allows for precise embedding of the anchors into the concrete using the positioning components, followed by connection to the prefabricated supports, enabling rapid installation of the concrete and supports. It also allows for easy disassembly, facilitating the reuse of the prefabricated supports and reducing assembly costs. The coordinated operation of the positioning components and the anchors ensures the bridge support device is firmly anchored, meeting the construction requirements and tight schedules in complex underground pipeline environments.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0032] Please refer to Figures 1 to 4As shown, this utility model provides a bridge support device that can ensure the pre-embedding accuracy of the pre-embedded components during concrete pouring and achieve rapid pre-embedding. It enables the rapid and intact assembly and disassembly of the prefabricated steel pipe support and the anchoring pre-embedded components, improving construction efficiency, reducing assembly costs, and ensuring that the bridge support device is firmly rooted, thereby meeting the construction requirements and tight schedule in complex underground pipeline environments. The bridge support device includes at least two concrete foundation formwork assemblies 1, positioning assemblies 2, column base anchors 3, and prefabricated supports 5. At least two concrete foundation formwork assemblies 1 are laid side by side adjacent to each other on the ground. Each concrete foundation formwork assembly 1 includes a steel reinforcement skeleton and a support frame 11. The support frame 11 contains a steel reinforcement skeleton for pouring concrete 4. The positioning assembly 2 includes at least four positioning elements and a connecting frame 22. The at least four positioning elements are all set on the connecting frame 22. Each positioning element has multiple positioning holes 23. The positioning assembly 2 is detachably connected to at least two adjacent concrete foundation formwork assemblies 1. When the positioning assembly 2 is connected to at least two adjacent concrete foundation formwork assemblies 1, each positioning hole 23 is spatially aligned with the corresponding connection part of the prefabricated support 5. The column base anchors 3 can be inserted into the positioning holes 23. The lower end of the column base anchors 3 is connected to the steel reinforcement skeleton, and the upper end of the column base anchors 3 extends beyond the upper surface of the positioning element and can be detachably connected to the prefabricated support 5.

[0033] Construction workers can first lay the concrete foundation formwork components 1 side by side at the expected laying position of the bridge support device, providing a foundation pouring position for the concrete 4 structure of the bridge support device; by detachably connecting the positioning components 2 across at least two adjacent concrete foundation formwork components 1, the assembly and disassembly of the positioning components 2 become more efficient, allowing the positioning components 2 to be reused and easily handled; combined with Figure 2 and Figure 3As shown, by setting the positioning component 2 on the connecting frame 22 and opening multiple positioning holes 23 on the positioning component, when the positioning component 2 is connected to at least two adjacent concrete foundation formwork components 1, each positioning hole 23 is spatially aligned with the corresponding connection part of the prefabricated bracket 5, and the column base anchor bolt 3 can be inserted into the positioning hole 23 for concrete 4 pouring, so that the column base anchor bolt 3 is pre-embedded in the concrete 4, ensuring the docking accuracy between the column base anchor bolt 3 and the prefabricated bracket 5; the lower end of the column base anchor bolt 3 is connected to the reinforcing steel of the concrete foundation formwork component 1. The upper end of the column base anchor 3 extends beyond the upper surface of the positioning component and can be detachably connected to the prefabricated bracket 5. The column base anchor 3 can be precisely pre-embedded into the concrete 4 using the positioning component 2, and then connected to the prefabricated bracket 5, realizing the rapid installation of the concrete 4 and the prefabricated bracket 5. It can also be completely disassembled to facilitate the reuse of the prefabricated bracket 5 and reduce assembly costs. Due to the synergistic cooperation between the positioning component 2 and the column base anchor 3, the bridge support device is firmly rooted, thereby meeting the construction requirements and tight schedule of complex underground pipeline environments.

[0034] like Figure 1 As shown, to improve the stability of the positioning component 2 structure, in some embodiments, the connecting frame 22 includes at least four connecting rods 221, which form a rectangle. At least four positioning elements are respectively located at the four corners of the connecting frame 22. The connecting frame 22, with at least four connecting rods 221 forming a rectangular structure, creates a closed support frame. Compared to a distributed support method, this improves overall rigidity, prevents displacement or deformation of the positioning elements during construction, and effectively resists structural instability caused by concrete pouring, formwork deformation, or external forces, thus improving construction accuracy and stability. Positioning the positioning elements at the four corners of the connecting frame 22 ensures precise alignment between the anchor points, making the connection between the prefabricated support 5 and the foundation structure more stable.

[0035] Furthermore, the connecting frame 22 is provided with reinforcing ribs 222 inside, wherein the reinforcing ribs 222 improve the overall rigidity of the connecting frame 22 and effectively prevent bending, twisting or deformation under concrete 4 pouring, support installation or external force.

[0036] Specifically, the reinforcing ribs 222 are arranged along the diagonal of the connecting frame 22; this makes the diagonal reinforcing ribs 222 form an X-shaped structure, which effectively enhances the torsional stiffness of the connecting frame 22, prevents the connecting frame 22 from twisting and deforming under stress, and ensures the stability and reliability of the bridge support device.

[0037] In other embodiments, the reinforcing rib 222 may also be in the form of a grid or similar shape, and is not specifically limited here.

[0038] To enhance the stability of the bridge support device, in some embodiments, the positioning component includes a positioning disk 21 with at least four positioning holes 23. The positioning disk 21 is spaced apart around the central axis of the positioning disk 21. The positioning disk 21 is designed to have the same shape as the prefabricated bracket base 52, which provides a wide contact surface between the two and increases stability. The positioning disk 21 has at least four positioning holes 23, which allows the column anchor bolts 3 to be fixed at multiple points, forming a stable anchoring system and improving the overall shear and torsional resistance. At the same time, the at least four positioning holes 23 are evenly spaced around the central axis to ensure that the anchor is subjected to uniform force and will not tilt or displace due to uneven force on one side.

[0039] Understandably, the positioning plate 21, connecting rod 221, and reinforcing rib 222 are readily available on the construction site, and scrap steel can be processed and assembled, effectively reducing costs while ensuring load-bearing capacity.

[0040] In some embodiments, the positioning plate 21 is fixedly connected to the connecting frame 22, which makes the entire connecting frame 22 a whole, avoiding the impact on anchoring accuracy due to loosening or misalignment. It should be noted that the positioning plate 21 and the connecting frame 22 may be connected by welding, but are not limited to this.

[0041] In other embodiments, the positioning disk 21 and the connecting frame 22 are detachably connected. When any positioning disk 21 in the field positioning assembly is damaged, since the positioning disk 21 and the connecting frame 22 are detachably connected, the damaged positioning disk 21 can be replaced at any time without replacing the entire positioning assembly 2, thus reducing costs and improving flexibility. It should be noted that the positioning disk 21 and the connecting frame 22 may be connected by bolts, but this is not a specific limitation.

[0042] To improve construction accuracy, in some embodiments, the positioning plate 21 is detachably equipped with a limiting component on the side facing away from the concrete foundation formwork assembly 1 to limit the insertion depth of the column anchor bolts 3. The limiting component effectively prevents the column anchor bolts 3 from being inserted too deeply or too shallowly, ensuring that all column anchor bolts 3 are at the same height and improving the installation accuracy of the bridge support device. Construction personnel can install the limiting component before inserting the column anchor bolts 3 to ensure all column anchor bolts 3 are at the same height. After the column anchor bolts 3 are pre-embedded, the limiting component can be removed before removing the positioning assembly 2. It should be noted that the limiting component can be, but is not limited to, limiting washers; no specific limitation is made here.

[0043] To facilitate the quick installation and disassembly of the positioning component 2, in some embodiments, the connecting frame 22 is provided with a buckle, which engages with the support frame 11. The buckle connection provides a simple and quick assembly method, reduces assembly time, and improves construction efficiency. At the same time, the buckle has a self-locking design, which can ensure a firm connection and reduce loosening caused by vibration, external force, or long-term use.

[0044] like Figure 4 As shown, to achieve flexible installation and disassembly of the prefabricated support 5, in some embodiments, the prefabricated support 5 includes a prefabricated support body 51 and a prefabricated support base 52. The prefabricated support base 52 is located at the end of the prefabricated support body 51 facing the concrete 4. The column anchor bolts 3 can pass through the prefabricated support base 52 and be bolted to it. The prefabricated support base 52 serves as a support point, effectively increasing the contact area between the support body and the concrete 4 foundation, thereby improving the stability and load-bearing capacity of the entire support and ensuring that the bridge support device can withstand large loads during use. Bolting the column anchor bolts 3 to the prefabricated support base 5 facilitates subsequent disassembly and maintenance, reducing the need for tools during installation and disassembly.

[0045] The following is the assembly process for bridge support devices:

[0046] First, according to the connection position of the assembled bracket 5, each positioning component on the positioning assembly 2 is connected to the connecting frame 22 so that the positioning holes 23 on it are aligned with the corresponding connection parts of the assembled bracket 5 in space.

[0047] Then, at least two concrete foundation formwork assemblies 1 are laid side by side adjacent to each other on the ground.

[0048] Then, the positioning component 2 is detachably straddled onto at least two adjacent concrete foundation formwork components 1;

[0049] Next, insert the column anchor bolt 3 into the positioning hole 23. The lower end of the column anchor bolt 3 is connected to the steel reinforcement cage, and the upper end of the column anchor bolt 3 extends beyond the upper surface of the positioning part.

[0050] Next, concrete 4 is poured into at least two adjacent concrete foundation formwork components 1, and column foot anchors 3 are pre-embedded.

[0051] Subsequently, after the pre-embedding is completed, the positioning component 2 is removed, and the column base anchor bolt 3 is detachably connected to the prefabricated bracket base 52.

[0052] Finally, after the construction is completed, the column anchor bolts 3 and the prefabricated bracket base 52 are removed, and the prefabricated bracket 5 is transferred to the next construction site.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
