Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically an adjustable horizontal coupling device. Background Technology

[0002] Bridge construction technology refers to the comprehensive technical field that, during the bridge engineering construction process, utilizes various scientific principles, technical means, and management methods to transform bridge design drawings into actual bridge structures, ensuring the achievement of goals such as bridge quality, safety, schedule, and cost. Full-span scaffolding is a construction method in which scaffolding is densely erected at appropriate intervals to provide support, according to design requirements. It is commonly used in cast-in-place bridge construction, such as cast-in-place box girders. In existing technologies, full-span scaffolding and steel pipe column scaffolding are typically used to construct bridges.

[0003] A full-span scaffold mainly consists of the following parts: scaffold foundation, uprights, horizontal bars, distribution beams, and bottom formwork. The scaffold foundation needs to be treated, and the concrete should be hardened after the bearing capacity meets the requirements. The uprights are the vertical support members that bear the main load. The horizontal bars are used to connect the uprights and increase the overall stability of the scaffold. The bottom formwork is used to directly contact the concrete and provide support for concrete pouring.

[0004] The steel pipe column support mainly consists of steel pipe columns, horizontal connecting rods, load-bearing beams, distribution beams, and bottom formwork. Among them, the steel pipe columns are the main vertical support components, bearing most of the load; the horizontal connecting rods are used to connect the steel pipe columns and enhance the overall integrity and stability of the support; the load-bearing beams are used to bear the lateral load and transfer it to the steel pipe columns; the distribution beams are similar to those in a full-span support system, used to distribute the load; and the bottom formwork provides a supporting surface for concrete pouring.

[0005] During installation and use, full-span scaffolding typically employs a dense arrangement of steel pipes using couplers or cup-lock systems to form a grid of longitudinal and transverse members. In contrast, steel pipe column scaffolding mainly consists of steel pipe columns, horizontal connecting rods, and load-bearing beams. Therefore, compared to full-span scaffolding, steel pipe column scaffolding offers advantages such as relatively simple structure, convenient installation, and strong load-bearing capacity, leading to its gradual promotion and application in bridge construction technology.

[0006] The function of horizontal bracing is to provide lateral support for steel pipe column supports, ensuring the overall stability of the supports and making it an indispensable part of the entire system. Current technology typically uses welding to horizontally brace the steel pipe columns, achieving a fixed connection between adjacent columns. However, welding damages the steel pipe columns, negatively impacting their strength. Furthermore, welding is time-consuming, involves hot work, and poses significant risks. It also hinders the later recycling of materials used in steel pipe column supports, leading to material waste and increased operating costs. Therefore, there is an urgent need for an adjustable horizontal bracing device to meet these requirements. Utility Model Content

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

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example: Figures 1 to 6As shown, an adjustable horizontal connection device is primarily designed to connect two adjacent steel pipe columns 1 laterally. It can adaptively adjust according to the distance between the two adjacent steel pipe columns 1, enhancing the user experience. Specifically, the horizontal connection device in this embodiment mainly consists of a horizontal connection component 2 and a clamp connection component 3. The clamp connection component 3 is installed outside the steel pipe column 1, primarily to achieve a stable connection between the clamp connection component 3 and the steel pipe column 1, and then the clamp connection component 3 is connected to the horizontal connection component 2 in an adjustable position. The horizontal connection component 2 is located between two steel pipe columns 1, and further, between two clamp connection components 3. The aforementioned clamp connection assembly 3 mainly consists of a clamp body 3-1 covering the steel pipe column 1 and a clamp connecting part 3-2 located on the side of the clamp body 3-1. To enhance the structural strength of the connection between the clamp body 3-1 and the clamp connecting part 3-2 and reduce the probability of separation, the clamp body 3-1 and the clamp connecting part 3-2 can be integrally formed and arranged perpendicularly. The aforementioned horizontal connection assembly 2 mainly consists of a horizontal connection body 2-1 and a horizontal connection body connecting part 2-2. The clamp connecting part 3-2 and the horizontal connection body connecting part 2-2 are connected and fixed by a connector 4. The position of the connector 4 is determined by the spacing between two adjacent steel pipe columns 1, so that the horizontal connection device can be adapted to steel pipe columns 1 with different spacings. The connector 4 can be a simple, reliable, and economical connecting bolt and nut.

[0030] To reduce connection difficulty and improve assembly efficiency, this embodiment provides a clamp connection hole 3-2-1 at the clamp connection part 3-2 and a horizontal connection hole 2-2-1 at the horizontal connection body connection part 2-2. The connector 4 passes through the clamp connection hole 3-2-1 and the horizontal connection hole 2-2-1. This hole arrangement facilitates the connection of the connector 4 and reduces damage to the clamp connection part 3-2 and the horizontal connection body connection part 2-2, ensuring their structural strength. To expand the adjustment range of the horizontal connection device and accommodate steel pipe columns 1 with greater spacing, this embodiment also designs both the horizontal connection hole 2-2-1 and the clamp connection hole 3-2-1 as oblong holes. In actual use, either the horizontal connection hole 2-2-1 or the clamp connection hole 3-2-1 is oblong, thus achieving adjustable functionality; the specific design can be adjusted as needed.

[0031] In order to achieve horizontal connection between multiple steel pipe columns 1, there are two clamp connection parts 3-2 in this embodiment. The two clamp connection parts 3-2 are symmetrically arranged along the central axis of the clamp body 3-1. One clamp connection part 3-2 is used to connect with the horizontal connection body connection part 2-2 located on the left side of the steel pipe column 1, and the other clamp connection part 3-2 is used to connect with the horizontal connection body connection part 2-2 located on the right side of the steel pipe column 1, so as to provide lateral support for the steel pipe column 1 and ensure the overall stability of the steel pipe column support.

[0032] The aforementioned horizontal connecting body 2-1 is a cuboid structure. Cuboid structures have relatively uniform stress characteristics, enabling them to better distribute and bear loads from different directions. This structural form ensures that all parts of the horizontal connecting body 2-1 are evenly stressed under various working conditions, reducing local stress concentration and thus improving the overall structural stability and safety. Furthermore, cuboid structures typically have high stiffness, effectively resisting deformation. During bridge construction, the horizontal connecting body 2-1 needs to withstand significant construction loads and environmental loads (such as wind loads and temperature changes). The cuboid structure can better maintain its shape and position, reducing deformation. In this embodiment, to enhance the stability of the horizontal connecting body 2-1 structure, four horizontal connecting body connection parts 2-2 are designed, each located at one of the four corners of the horizontal connecting body 2-1. In this embodiment, by placing the aforementioned horizontal coupling main body connection portion 2-2 at the four corners, the load can be evenly distributed across the four corners of the horizontal coupling main body 2-1. This design effectively avoids local stress concentration, ensuring a more uniform stress distribution throughout the structure and thus improving overall structural stability. To ensure connection strength, the aforementioned horizontal coupling main body connection portion 2-2 and the aforementioned horizontal coupling main body 2-1 can be fixed together by welding or other methods.

[0033] In this embodiment, the aforementioned horizontal connecting body 2-1 mainly consists of a pair of oppositely arranged horizontal beams 2-1-1 and a pair of oppositely arranged vertical beams 2-1-2. The pair of vertical beams 2-1-2 are vertically installed between the pair of horizontal beams 2-1-1. A support beam 2-1-3 is also vertically installed between the pair of horizontal beams 2-1-1. A structural reinforcing beam 2-1-4 arranged at an angle connects the pair of vertical beams 2-1-2 and the support beam 2-1-3 to ensure the structural strength of the horizontal connecting body 2-1 itself. The horizontal beams 2-1-1, the vertical beams 2-1-2, the support beams 2-1-3, and the structural reinforcing beams 2-1-4 are all made of channel steel, a high-strength steel with high tensile, compressive, and bending strength. Using channel steel to fabricate the horizontal beam 2-1-1, vertical beam 2-1-2, support beam 2-1-3, and structural reinforcement beam 2-14 ensures that these components remain stable under heavy loads, meeting the load-bearing requirements of bridge construction. Furthermore, channel steel possesses good toughness, enabling it to withstand impact and dynamic loads to a certain extent, adapting to various complex conditions that may arise during bridge construction. Simultaneously, since channel steel is a standardized building material with various specifications available on the market, it facilitates procurement and processing. This standardized production reduces processing time and costs, improving construction efficiency.

[0034] The aforementioned clamp body 3-1 includes a pair of opposing and separate clamp plates 3-1-1. The clamp plates 3-1-1 are curved and their inner diameter matches the outer diameter of the steel pipe column 1, so as to fix them to the outside of the steel pipe column 1. In order to facilitate assembly and to avoid damage to the clamp plates 3-1-1, in this embodiment, a tie plate 3-1-2 is integrally formed on the edge of the clamp plates 3-1-1. A tie plate connecting hole 3-1-3 is provided at the tie plate 3-1-2, and a locking member 3-1-4, which is a locking bolt, is inserted into the tie plate connecting hole 3-1-3.

[0035] To facilitate adjustment and reduce adjustment difficulty, and also to facilitate assembly, both the above-mentioned flat main body connecting part 2-2 and the above-mentioned clamp connecting part 3-2 are set in a flat plate shape.

[0036] In this embodiment of the adjustable horizontal coupling device, the steel pipe column 1 is first installed. After ensuring the verticality of the steel pipe column 1, the horizontal coupling assembly 2 is hoisted to the designated position. The clamp connection part 3-2 on the side of the clamp plate 3-1-1 in the clamp connection assembly 3 is tightly attached to the horizontal coupling body connection part 2-2 and connected and fixed by the connector 4. After completion, another clamp plate 3-1-1 is hoisted and arranged symmetrically with the above clamp plate 3-1 around the steel pipe column 1. After aligning with the stiffener plate connection hole 3-1-3, it is connected with fastening bolts to complete the clamp installation at one corner of the horizontal coupling body 2-1. The above steps are repeated three times to complete the installation of the horizontal coupling clamps at the remaining three corners of the horizontal coupling body 2-1.

[0037] Since both the flat coupling component 2 and the clamp connection component 3 are prefabricated in the factory and installed on site, the dismantling time is greatly shortened and the dismantling efficiency is improved.

[0038] This embodiment presents an adjustable horizontal coupling device. The device comprises a horizontal coupling assembly 2 and a clamp connection assembly 3. The clamp connection assembly 3 includes a clamp body 3-1 installed outside the steel pipe column 1 and a clamp connection part 3-2 fixedly connected to the clamp body 3-1. The horizontal coupling assembly 2 includes a horizontal coupling body 2-1 and a horizontal coupling connection part 2-2. During assembly, the clamp connection part 3-2 and the horizontal coupling connection part 2-2 are connected and fixed by a connector 4. The specific position of this connection point can be adjusted according to the spacing between two adjacent steel pipe columns 1, making the entire horizontal coupling device adjustable to accommodate steel pipe columns 1 with different spacings, thus enhancing its practicality. This adjustable horizontal coupling device has a simple and ingenious structure, is easy to operate, and enables horizontal coupling between steel pipe columns 1 while facilitating subsequent disassembly, recycling, and reuse. This reduces material waste, enhances the user experience, and promotes the application of this adjustable horizontal coupling device in the field of bridge construction technology.
