Description

Technical Field

[0001] The utility model relates to the technical field of bridge supports, and specifically relates to a bridge tensile auxiliary support with rapid assembly construction. Background Art

[0002] When a bridge structure is subjected to load, it will generate pressure and tension. A tension bearing, also known as a negative reaction bearing, is a bearing that can withstand positive and negative reaction forces at the same time. In bridge engineering, on continuous beam bridges, cantilever beam bridges, inclined bridges and small radius curve bridges, tension is generated at certain fulcrums due to the action of loads. In this case, a bearing that can resist tension and withstand corresponding rotation and horizontal displacement must be set. Therefore, the setting of tension bearings is to meet the needs of these special structures when subjected to tension. There are mainly the following types of tension bearings: Plate rubber tension and compression bearings are mainly composed of a rubber layer and a steel plate to form a plane structure. The rubber layer and the steel plate are tightly bonded by an adhesive to jointly bear the load of the bridge. It is suitable for bridges with smaller tension. The pot tension bearing is a circular or elliptical structure composed of a rubber layer and a steel pot. This structural form makes the pot tension bearing have better stability and bearing capacity when subjected to tension. Spherical tensile steel bearings are also used to withstand large tensile forces. Their spherical design makes stress distribution more uniform, improving the stability and safety of the bearings.

[0003] Due to the difference in structure and working principle, the pot-type tension bearing has a relatively large bearing capacity and is suitable for large-span, heavy-loaded bridges. The plate-type rubber tension-compression bearing has a relatively small bearing capacity and is more suitable for small and medium-span, light-loaded bridges. Compared with the traditional simple bearing structure, the tension bearing is more complex and contains more components and connectors. This complexity not only increases the difficulty of manufacturing and installation, but may also lead to more potential problems during use. Since the manufacturing process of the tension bearing requires special materials and processes, as well as more complicated installation and maintenance procedures, its cost is usually higher. This may become a disadvantage for some engineering projects with limited budgets. The installation of the tension bearing requires professional skills and experience to ensure that it works correctly and stably. In addition, due to the complexity of its structure, it is relatively difficult to maintain and requires regular inspection, adjustment and replacement of parts.

[0004] With the continuous development of bridge and construction technology, the performance requirements for bearings are getting higher and higher. The research and development and application of tension bearings are precisely to meet these growing technical needs. In view of the above situation, this design proposes a bridge tensile auxiliary bearing with rapid assembly construction. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bridge tensile auxiliary support with rapid assembly construction, including a steel mesh concrete abutment, the steel mesh concrete abutment is vertically symmetrically arranged up and down, a steel guide rail is fitted between the inner walls of the two steel mesh concrete abutments, the side walls of the steel guide rail are symmetrically fixedly connected with side steel plates, the inner cavity of the side steel plate is sleeved with a first bolt, the side steel plate is fixedly connected to the steel mesh concrete abutment by the first bolt, and the inner cavities of the two steel guide rails are inserted with I-beam webs.

[0007] Preferably, it further comprises a guide structure, wherein the number of the guide structures is two and they are arranged laterally symmetrically, and the upper and lower ends of the guide structure are in contact with the side walls of the steel guide rail.

[0009] Preferably, the four corners of the side wall of the I-beam web are symmetrically fixedly connected with steel protrusions, and the side walls of the steel protrusions are in contact with the side walls of the steel guide rails.

Rapid assembly construction reduces on-site wet work and reduces the emission of pollutants such as construction noise and dust, which is beneficial to environmental protection. At the same time, the manufacturing and assembly process of prefabricated components can also achieve efficient utilization of resources, reduce material waste, and conform to the development trend of green buildings.
