I-shaped steel socket type tramcar prefabricated track beam and tubular pile connecting structure and construction method

Abstract

The invention relates to the technical field of constructional engineering, in particular to an I-shaped steel socket type tramcar prefabricated track beam and pipe pile connecting structure and a construction method, I-shaped steel is embedded in the top of a pipe pile, a groove matched with the I-shaped steel is formed in the bottom of a prefabricated track beam, the groove is arranged on the I-shaped steel in a sleeving mode, and the I-shaped steel is connected with the pipe pile in a sleeving mode. Ultra-high performance concrete is poured between the groove and the I-shaped steel, and connection between the prefabricated track beam and the pipe pile is achieved. The method has the advantages that up-and-down vibration when an accident occurs can be effectively dealt with, the problems that positioning is difficult, the tolerance rate is small, much manpower is needed, and construction time is slow when a conventional precast beam and a pipe pile are connected are solved, rapid connection of sheet piles is achieved, manpower and time cost needed during connection is reduced, and the construction efficiency is improved. And the structural bearing capacity during connection is improved through the ultra-high performance concrete.

Description

Technical field [0001] The present invention relates to the field of construction engineering technology, in particular an I-beam type steel socket tram prefabricated rail beam and pipe pile connection structure and construction method. Background [0002] With the acceleration of China's urbanization construction process, the state vigorously promotes "building industrialization and housing industrialization", while meeting the green and carpet requirements of buildings, and promoting the structural adjustment and sustainable development of China's construction industry, so as to develop prefabricated concrete structures is the only way. [0003] For prefabricated concrete structures, the nodes of prefabricated components are the weak links of the prefabricated structure, and the prefabricated concrete frame structural system, the main structure of the boards and columns can be processed in the factory, as long as they are spliced on the site. Factory processing can objectively ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a connection structure and construction method between the prefabricated track beam and the pipe pile of the I-shaped steel socket type tramcar according to the above-mentioned deficiencies in the prior art. The socket connection structure of slot and I-shaped steel overcomes the problems of difficult positioning, small tolerance rate, large manpower required, and slow construction time when connecting conventional prefabricated beams and pipe piles, and realizes fast connection of sheet piles, reducing the time spent on connection. The required labor and time costs, and the structural bearing capacity of the connection is improved through ultra-high performance concrete
