[0022] The technical solution of the utility model will be further described below with reference to the drawings and through specific embodiments:
[0023] Embodiment 1
[0024] Refer to the attached Figures 1 to 4 The utility model is a prefabricated and assembled connection node structure for bridge piers and capping beams. The utility model sets a connection node structure for positioning connection at the connection between the capping beam and the pier column to achieve a fast, stable and durable connection method, so as to improve the overall performance and construction efficiency of the bridge structure.
[0025] The specific connection structure is as follows:
[0026] As Figure 3 The capping beam 100 is an important part of the upper structure of the bridge, on which a cavity cylinder 110 is provided. A web 120 is provided inside the cavity cylinder 110, and the height difference between the web 120 and the cavity cylinder 110 forms a positioning groove 130. This design enables the capping beam 100 to form a tight fit with the bridge pier 200.
[0027] The cavity tube 110 is a key component on the capping beam 100, and its internal space is provided with a web 120. The design of the cavity tube 110 allows the positioning arc plate 210 and shear studs 220 of the pier 200 to be embedded, achieving precise positioning.
[0028] The web 120 is arranged inside the cavity tube 110 and has a height difference from the cavity tube 110. The step formed by this height difference is the positioning groove 130. The presence of the web 120 improves the load-bearing capacity of the capping beam 100 and provides structural support for positioning.
[0029] The capping beam 100 is provided with grouting holes 140 for pouring concrete, forming a stable connection node structure with the shear studs 220. The grouting holes 140 allow the concrete to fully fill the space between the capping beam 100 and the pier 200, and a stable connection is formed after curing.
[0030] As Figure 4 shown, the pier 200 is provided with a positioning arc plate 210 and shear studs 220. The positioning arc plate 210 is arranged on the end face of the pier 200 and is symmetrically distributed. Shear studs 220 are arranged between the two groups of positioning arc plates 210.
[0031] The design of the positioning arc plate 210 is used to cooperate with the cavity tube 110 and the web 120 on the capping beam 100 to achieve precise docking of the capping beam and the pier.
[0032] The shear studs 220 are embedded in the positioning arc plate 210 and cooperate with the cavity tube 110 and the web 120 on the capping beam 100 to enhance the stability of the connection.
[0033] Construction method
[0034] Manufacture of precast components: First, manufacture the precast components of the capping beam 100 and the pier 200 in the factory to ensure dimensional accuracy and quality control.
[0035] On-site installation: Transport the precast capping beam 100 and pier 200 to the construction site and use a lifting machine for hoisting.
[0036] Positioning and adjustment: Use the positioning groove 130 on the capping beam 100 and the positioning arc plate 210 on the pier 200 for precise positioning to ensure accurate cooperation between the two.
[0037] Grouting construction: Pour concrete through the grouting holes 140 on the capping beam 100. After the concrete cures, a stable connection node is formed.
[0038] Quality inspection: After the construction is completed, conduct quality inspection to ensure that the stability and load-bearing capacity of the connection node meet the design requirements.
