Steel pipe socket type tramcar prefabricated track beam and pipe pile connecting structure and construction method

Abstract

The invention relates to the technical field of constructional engineering, in particular to a steel pipe socket type tramcar prefabricated track beam and pipe pile connecting structure and a construction method.The top of a pipe pile is embedded with a cylindrical steel pipe, the bottom of a prefabricated track beam is provided with a groove matched with the cylindrical steel pipe, the cylindrical steel pipe is sleeved with the groove, and the cylindrical steel pipe is connected with the prefabricated track beam through a steel pipe; ultra-high performance concrete is poured between the groove and the cylindrical steel pipe, and connection between the prefabricated track beam and the pipe pile is achieved. The method has the advantages that the problems that when a conventional precast beam and a pipe pile are connected, positioning is difficult, the tolerance rate is small, much manpower is needed, and the construction time is short are solved, rapid connection of the sheet piles is achieved, the manpower and time cost needed during connection is reduced, 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 a steel pipe 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 ensure t...

Problems solved by technology

[0005] The object of the present invention is to provide a connection structure and construction method between a steel pipe socket type tramway prefabricated track beam and a pipe pile according to the above-mentioned deficiencies in the prior art. The socket connection structure of cylindrical steel pipes 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 required for connection. Labor and time costs, and increase the structural bearing capacity of the connection through ultra-high performance concrete
