Description

Technical Field

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

[0002] Bridges, as vital structures connecting banks and overcoming obstacles, play a crucial role. With technological advancements, bridge structures have become increasingly diverse, with cable-stayed bridges and suspension bridges emerging as leaders in modern transportation engineering. However, regardless of whether it's a cable-stayed or suspension bridge, the pylon is an indispensable structural element. Specifically, a pylon typically comprises upper, middle, and lower crossbeams. If the upper and middle crossbeams are constructed using cast-in-place concrete, corresponding support structures are required for construction. However, the upper and middle crossbeams are generally quite high, and commonly used ground-mounted steel pipe supports are not only unsafe but also costly. Therefore, bracket structures are now commonly used for construction. Furthermore, when bracket structures are used on pylons, temporary support structures are often required as fulcrums to support the self-weight of the supporting brackets and crossbeams, as well as various loads during crossbeam construction. These support structures are typically corbels, providing stable support and transferring loads during construction and maintenance, playing a vital role in the construction process.

[0003] In bridge construction, the commonly used corbel structures are climbing cone and pin-type corbels. These corbels require pre-embedding of the climbing cone and steel plate during tower construction, along with pre-drilled holes matching the pin diameter. This allows the corbel to be connected to other parts to form a unified structure during bracket installation. However, with increasing support reaction forces, the pin size also increases. Oversized pins can conflict with the placement of the tower's vertical main reinforcement bars, typically affecting one or two bars. This necessitates special treatment of their installation location, which can damage the internal steel reinforcement framework of the tower, posing a safety hazard.

[0004] Therefore, how to ensure that the installation of the corbel structure does not damage the internal steel reinforcement frame of the tower, while also effectively improving the overall construction speed and reducing construction risks, is a problem that needs to be solved by those in this field. Utility Model Content

[0005] The purpose of this invention is to provide a pre-embedded support bracket so that the installation of the bracket structure does not damage the internal steel reinforcement skeleton structure of the tower, and can also effectively improve the overall construction speed and reduce construction risks.

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

[0007] An embedded support bracket, which can be embedded in a cable tower, comprises:

[0008] The pre-embedded part and the corbel part are provided. The pre-embedded part is embedded in the tower and can avoid the stirrups in the tower. The corbel part is vertically connected to the pre-embedded part and is set on the outside of the tower.

[0009] Optionally, the embedded part includes an embedded steel plate and a plurality of embedded inserts, the plurality of embedded inserts being arranged parallel to and spaced apart on one side of the embedded steel plate, and the embedded inserts being embedded in the cable tower.

[0010] Alternatively, the distance between two adjacent embedded plates may be greater than the outer diameter of the stirrup.

[0011] Alternatively, the thickness of the embedded steel plate is set to 30 mm, and the thickness of the embedded insert plate is set to 20 mm.

[0012] Alternatively, the embedded insert is arranged perpendicular to the embedded steel plate, and the bracket is perpendicularly connected to the other side of the embedded steel plate.

[0013] Optionally, the cow leg includes a horizontal plate and a web plate, the horizontal plate, the web plate and the embedded steel plate being arranged perpendicularly to each other in pairs, with the horizontal plate located at the top and the web plate located below the horizontal plate.

[0014] Alternatively, the web may be provided in three parallel and spaced-apart configurations on the horizontal plate.

[0015] Optionally, the cow's leg may also be provided with a short plate, which is located between two adjacent abdominal plates.

[0016] Alternatively, the short plate may be arranged parallel to the horizontal plate and perpendicular to the web plate.

[0017] Alternatively, the embedded part and the corbel part are connected by welding.

[0018] The beneficial effects of this utility model are:

[0019] This utility model's pre-embedded support bracket comprises two parts: an embedded part and a bracket part. This allows for separate installation as needed during the installation process, enabling factory fabrication and reducing on-site welding, thereby improving installation efficiency and quality. Simultaneously, the embedded part avoids interference with the stirrups in the cable tower, preventing interference with the installation of the cable tower's steel reinforcement cage and eliminating the need for special structural treatment. This ensures the integrity and aesthetics of the cable tower's internal and external structures. Furthermore, it provides the necessary support reaction force during construction, guaranteeing overall construction safety and reducing construction risks. Attached Figure Description

[0029] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.

[0030] like Figures 1-4 As shown, this embodiment provides a pre-embedded support bracket that can be embedded in the tower 100. The pre-embedded support bracket includes a pre-embedded part 10 and a bracket part 20. The pre-embedded part 10 is pre-embedded in the tower 100 and can avoid the stirrups in the tower 100. The bracket part 20 is vertically connected to the pre-embedded part 10 and is located on the outside of the tower 100.

[0031] Specifically, in this embodiment, the pre-embedded support bracket includes two parts: the pre-embedded part 10 and the bracket part 20. This allows for separate installation as needed during the installation process, enabling separate processing in the factory, thereby reducing on-site welding and improving installation efficiency and quality. Simultaneously, the pre-embedded part 10 avoids interference with the stirrups in the tower 100, not only preventing interference with the installation of the steel reinforcement cage in the tower 100 and avoiding special structural treatment, thus ensuring the integrity and aesthetics of the tower 100's internal and external structures, but also providing the necessary support reaction force during construction, ensuring overall construction safety and reducing construction risks.

[0032] The specific structure of the pre-embedded support bracket in this embodiment is described below.

[0033] like Figure 1 and Figure 2 As shown, in this embodiment, the pre-embedded support bracket includes a pre-embedded part 10 and a bracket part 20, which can be connected by welding to ensure a stable connection of the overall structure. Specifically, the pre-embedded part 10 is pre-embedded in the tower 100, and the pre-embedded part 10 can avoid the stirrups in the tower 100, so that the pre-embedded support bracket does not need to be processed during the installation of the stirrups. Further, the bracket part 20 is vertically connected to the pre-embedded part 10 and is set on the outside of the tower 100 to provide support.

[0034] Combination Figures 1-4 As shown, in this embodiment, the pre-embedded part 10 includes a pre-embedded steel plate 11 and a plurality of pre-embedded insert plates 12. The plurality of pre-embedded insert plates 12 are arranged parallel to each other and spaced apart on one side of the pre-embedded steel plate 11. The specific number and position of the pre-embedded insert plates 12 can be set as needed. For example, in this embodiment, the pre-embedded insert plates 12 are arranged in four columns, and each column is provided with at least 9 plates. Further, the pre-embedded insert plates 12 are pre-embedded in the cable tower 100, thereby realizing that the pre-embedded support bracket can be pre-embedded in the cable tower 100.

[0035] Specifically, the distance between two adjacent embedded plates 12 is greater than the outer diameter of the stirrups in the tower 100, thereby effectively avoiding damage to the structure of the tower 100. Exemplarily, in this embodiment, the embedded plate 12 is positioned perpendicular to one side of the embedded steel plate 11, and the bracket 20 is perpendicularly connected to the other side of the embedded steel plate 11, ensuring stable installation of both parts of the embedded support bracket under the connection of the embedded steel plate 11. Exemplarily, in this embodiment, the thickness of the embedded steel plate 11 is set to 30mm, and the thickness of the embedded plate 12 is set to 20mm; in other embodiments, these thicknesses can be adjusted as needed. Furthermore, the width of the embedded plate 12 can be defined according to the net spacing of the stirrups in the tower 100 to ensure that the width is less than the spacing of the stirrups in the tower 100, and the length of the embedded plate 12 can be determined based on the actual stress.

[0036] Optionally, in this embodiment, the cow leg portion 20 includes a horizontal plate 21, a web plate 22, and a short plate 23. Specifically, the horizontal plate 21, the web plate 22, and the embedded steel plate 11 are arranged perpendicularly to each other in pairs, with the horizontal plate 21 positioned at the top and the web plate 22 located below it. The width of the horizontal plate 21 is greater than the length of the web plate 22, thus covering the top of the web plate 22. For example, in this embodiment, three web plates 22 are provided, arranged parallel and spaced apart on the horizontal plate 21, thereby dividing the area below the horizontal plate 21 into two spaces. Specifically, the lower outer side of the web plate 22 is chamfered, and one side of the long side of the web plate 22 is connected to the embedded steel plate 11, thereby increasing the connection area between the cow leg portion 20 and the embedded portion 10, and ensuring a stable connection between the two.

[0037] Furthermore, short plates 23 are disposed between two adjacent web plates 22 to ensure the stable installation of the web plates 22. Specifically, the short plates 23 are disposed parallel to the horizontal plate 21 and perpendicular to the web plates 22, thereby further dividing the space between two adjacent web plates 22. Exemplarily, in this embodiment, at least four short plates 23 are disposed, with two short plates 23 disposed between every two web plates 22. Specifically, the length of the short plates 23 is the same as the length of the web plates 22, thereby avoiding interference with other structures and further improving the stability of the web plates 22 to prevent swaying. Exemplarily, one side of the short side of the short plate 23 is connected to the embedded steel plate 11, which can further expand the connection area between the bracket portion 20 and the embedded portion 10, thereby enabling the bracket portion 20 to form a grid-like structure with higher mechanical strength and better stability.

[0038] Manufacturing and Application Process: First, the embedded steel plate 11 and embedded insert plate 12 in the embedded part 10 can be manufactured in the factory. The dimensions of both can be calculated based on the actual needs using support reaction force. After processing, the embedded insert plate 12 and the embedded steel plate 11 can be connected by welding to form the embedded part 10. Then, after the steel reinforcement cage in the tower 100 is tied, accurate measurement and positioning can be carried out to determine the position of the entire embedded support bracket. The above-mentioned processed embedded part 10 is then embedded at this position, and concrete is poured into the tower 10. Finally, the crossbeam bracket construction work is carried out. Similar to the first step, the horizontal plate 21, web plate 22, and short plate 23 of the corbel 20 are manufactured in the factory. Their dimensions are also determined based on the actual required support reaction force. After processing, the various structures are welded together to form the corbel 20. Finally, before the bracket is installed, the corbel 20 is welded to the embedded part 10. Before welding, the length of the weld, the length of the stiffening plate, and the size of the weld need to be accurately calculated. During the welding process, the on-site welding quality needs to be strictly controlled to meet the design requirements. After the weld is inspected and approved, the bracket is installed, thereby achieving a stable support effect through the embedded support corbel.

[0039] In summary, the pre-embedded support bracket in this embodiment has a simple structure and allows for flexible construction. The structure is divided into two parts: the pre-embedded part 10 and the bracket part 20. This allows for pre-fabrication in the factory and direct on-site installation, improving construction quality and reducing on-site welding. Furthermore, it effectively controls construction quality and safety while increasing the efficiency of beam and bracket installation in the tower 100. For example, the dimensions of the pre-embedded steel plate 11 in the pre-embedded part 10 and the spacing of the pre-embedded inserts 12 can be arranged according to the specific structure of the steel reinforcement skeleton in the tower 100, enabling adaptive adjustment. This significantly reduces damage to the internal structure of the tower 100, ensuring the aesthetics of the external structure and providing certain economic benefits.
