Description

Technical Field

[0001] This utility model belongs to the field of bridge construction technology, and in particular to a bridge direct connection installation clamp. Background Technology

[0002] In bridge construction, a connection device is typically needed to quickly and reliably install and fix temporary working platforms or load-bearing structures such as scaffolding, support structures, and formwork systems to the main bridge structure (e.g., columns, beams, and support poles). Among these, clamp structures, as a commonly used non-perforated, weld-free fastening connection method, are widely used in bridge construction for scaffold erection. Traditional clamps are mostly integral or split steel band clamps, which use bolts to tighten and cover the main structure, and then extend to connect other components. However, with the increasing complexity of bridge engineering, traditional clamps have gradually revealed many shortcomings in terms of connection versatility, spatial adaptability, and installation efficiency.

[0003] Traditional bridge connecting clamps typically have only one or two connection points, and the connection direction is relatively fixed (e.g., they can only extend to one side), making it difficult to simultaneously connect multiple components such as crossbars, diagonal braces, and columns. These clamps often use a simple ring-shaped strip structure, which is fastened to the bridge frame with bolts. Their outer walls lack expandable connection interfaces, resulting in them being only suitable for supporting components in a single direction (e.g., they can only connect vertical columns), and thus cannot effectively meet the needs of complex spatial structures. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a bridge direct connection installation clamp.

[0005] The purpose of this utility model is achieved through the following technical solution: a bridge direct connection installation clamp, including a first arc-shaped semi-clamp and a second arc-shaped semi-clamp. The first and second arc-shaped semi-clamps are spliced ​​together to form an integral clamp directly installed on the bridge construction erection frame. At least two U-shaped connecting plates are symmetrically welded to the curved outer wall of the first arc-shaped semi-clamp facing away from the second arc-shaped semi-clamp. The U-shaped connecting plates can be connected and installed with external bridge construction erection supports. At least two transverse extension connecting plates are symmetrically welded to the curved outer wall of the second arc-shaped semi-clamp facing away from the first arc-shaped semi-clamp. Each transverse extension connecting plate or two opposite transverse extension connecting plates are connected to a crossbar frame of the bridge construction erection by a pin. A longitudinal extension connecting plate is welded to the end of each transverse extension connecting plate away from the second arc-shaped semi-clamp. Each longitudinal extension connecting plate has arc-shaped installation ends at both the upper and lower ends. An inclined frame is connected between two opposite arc-shaped installation ends by a pin.

[0006] In this preferred embodiment, the ends of both inclined rods near the arc-shaped mounting ends can be hinged to the arc-shaped mounting ends via pins, making the inclination angle of the inclined rods adjustable.

[0007] In this preferred embodiment, the ends of the two U-shaped connecting plates furthest from the first arc-shaped semi-clamp are connected to the support components via connecting bolts.

[0008] In a preferred embodiment of this solution, the support frame component includes an installation plate, which is connected and installed at the end of a U-shaped connecting plate.

[0009] In a preferred embodiment of this scheme, the support frame component further includes a longitudinal mounting column, which is connected and installed at the end of the U-shaped connecting plate.

[0010] In this preferred embodiment, each of the U-shaped connecting plates, after being enclosed by the first arc-shaped semi-clamp, forms an internal mounting cavity.

[0011] In this preferred embodiment, the outer walls of the two free ends of the first and second arc-shaped semi-clamps are welded with connecting lugs, and the two connecting lugs are fastened together by locking bolts and locking nuts, so that the first and second arc-shaped semi-clamps are fastened together.

[0012] The beneficial effects of this utility model are: 1) The design, which involves symmetrically welding at least two U-shaped connecting plates to the outer wall of the first arc-shaped semi-clamp, enables the device to connect to external support structures at multiple points, achieving modular expansion capabilities and improving construction flexibility and adaptability. The U-shaped connecting plates provide standardized interfaces for subsequent connections to other structures, such as mounting panels and longitudinal columns, supporting rapid installation and disassembly of various types of supports. Simultaneously, the U-shaped structure itself has a certain tolerance, accommodating connecting components of different sizes and shapes, thus improving the overall structure's versatility and compatibility.

[0013] 2) The design, featuring symmetrically welded transverse extension connecting plates on the outer wall of the second arc-shaped semi-clamp, and longitudinal extension connecting plates and arc-shaped installation ends at its ends, enables the device to efficiently connect the horizontal and inclined frames, achieving synchronous longitudinal and transverse connection. This enhances the overall stability and spatial adaptability of the support system. This combined structure forms a complete "transverse-longitudinal-inclined" three-dimensional connection system, effectively dispersing forces from different directions and enhancing the overall rigidity and anti-overturning capacity of the structure. In particular, the pin-hinged connection of the inclined frames allows for flexible adjustment of the frame angle according to actual working conditions, further improving the device's adaptability to complex terrain and irregular layouts.

[0014] 3) The installation cavity formed by the U-shaped connecting plate and the first arc-shaped semi-clamp allows the device to insert and fix the support column, achieving a dual connection function (i.e., snap-fit ​​+ plug-in), thus enhancing connection reliability and applicability. This cavity structure can not only be used to connect the expansion components on the U-shaped plate, but also as an independent plug-in hole, greatly enriching the connection forms of the clamp and improving its practicality in different construction scenarios.

Detailed Implementation

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] See Figures 1-3This utility model provides a bridge direct connection installation clamp, including a first arc-shaped semi-clamp 1 and a second arc-shaped semi-clamp 2. The first arc-shaped semi-clamp 1 and the second arc-shaped semi-clamp 2 are spliced ​​together to form an integral clamp that can be directly installed on the bridge construction erection frame. At least two U-shaped connecting plates 9 are symmetrically welded to the curved outer wall of the first arc-shaped semi-clamp 1 facing away from the second arc-shaped semi-clamp 2. The U-shaped connecting plates 9 can be connected and installed with different external bridge construction erection supports. At least two transverse extension connecting plates 6 are symmetrically welded to the curved outer wall of the second arc-shaped semi-clamp 2 facing away from the first arc-shaped semi-clamp 1. Each transverse extension connecting plate 6 or two opposite transverse extension connecting plates 6 are connected to the crossbar frame 13 of the bridge construction erection by a pin. A longitudinal extension connecting plate 7 is welded to the end of each transverse extension connecting plate 6 away from the second arc-shaped semi-clamp 2. Each longitudinal extension connecting plate 7 has arc-shaped installation ends 8 at both the upper and lower ends. An inclined frame 14 is connected between two opposite arc-shaped installation ends 8 by a pin. The design of the horizontal extension connecting plate 6 and the vertical extension connecting plate 7 can not only connect the erected horizontal frame 13, but also connect the two inclined frames 14, improving the connection efficiency and realizing the rapid connection of the support frame with the columns.

[0019] In this embodiment, the ends of the two tilting rods 14 near the arc-shaped mounting end 8 can be hinged to the arc-shaped mounting end 8 via pins, so that the tilt angle of the tilting rods 14 is adjustable.

[0020] In this embodiment, the ends of the two U-shaped connecting plates 9 that are away from the first arc-shaped semi-clamp 1 are connected to the support components by connecting bolts 11.

[0021] In this embodiment, the support frame component includes a mounting plate 12, which is connected and installed at the end of a U-shaped connecting plate 9.

[0022] In this embodiment, in some embodiments the support structure also includes a longitudinal column 15, which is connected to the end of the U-shaped connecting plate 9. In this embodiment, after each U-shaped connecting plate 9 is enclosed with the first arc-shaped semi-clamp 1, an installation enclosure cavity 10 is formed inside, and the installation enclosure cavity 10 can optionally be connected to the support column.

[0023] In this embodiment, the outer walls of the two free ends of the first arc-shaped semi-clamp 1 and the second arc-shaped semi-clamp 2 are both welded with connecting ear plates 3. The two connecting ear plates 3 are fastened together by locking bolts 4 and locking nuts 5, so that the first arc-shaped semi-clamp 1 and the second arc-shaped semi-clamp 2 are fastened together.

[0024] Working principle The bridge directly connects to the installation of clamps. The first and second arc-shaped semi-clamps 1 and 2 are respectively placed around both sides of the bridge construction scaffold. After being spliced ​​together, they form a complete ring structure that fits tightly against the outer wall of the scaffold. Connecting lugs 3 are welded to the free ends of both clamps, and are tightened using locking bolts 4 and locking nuts 5, ensuring the entire clamp is firmly fixed to the scaffold and preventing slippage or loosening. This ensures a reliable connection between the clamp structure and the main bridge structure, serving as the foundation support point for all subsequent expansion connections.

[0025] The open end of each U-shaped connecting plate 9 can be connected to external support components such as mounting plate 12 or mounting column 15 via connecting bolt 11. After the U-shaped connecting plate 9 is enclosed by the first arc-shaped semi-clamp 1, an installation enclosure cavity 10 is formed inside, which can be used to insert and fix support columns and other components, providing multi-directional and multi-purpose connection interfaces, facilitating the rapid construction of various types of support structures.

[0026] On the curved outer wall of the second arc-shaped semi-clamp 2 facing away from the first arc-shaped semi-clamp 1, at least two transverse extension connecting plates 6 are symmetrically welded. The transverse extension connecting plates 6 are connected to the horizontal frame 13 used for bridge construction by means of pins to achieve horizontal support. Each transverse extension connecting plate 6 has a longitudinal extension connecting plate 7 welded to the end away from the clamp. The upper and lower ends of the longitudinal extension connecting plate 7 are provided with arc-shaped installation ends 8 for hinged connection with the inclined frame 14 to build a crisscrossing three-dimensional support system to meet the force requirements of different angles and directions.

[0027] The upper and lower ends of the inclined frame 14 are hinged to the corresponding arc-shaped mounting ends 8 via pins. Due to the existence of the hinge structure, the tilt angle of the inclined frame 14 can be flexibly adjusted according to actual construction needs. This adjustable design improves the adaptability of the clamp structure to complex terrain and irregular support layouts. It enhances the flexibility and adaptability of the structure and improves the stability and safety of the overall system.

[0028] Depending on construction requirements, different extension components can be selectively connected to the ends of the U-shaped connecting plate 9: such as mounting plates 12 for vertical support or mounting longitudinal columns 15 for connection in high-rise structures. These extension structures can be quickly installed using bolts or pins, facilitating on-site operation.
