Embodiment Construction

[0026] The present invention will be further described below in conjunction with the examples, and the purpose is only to better understand the content of the present invention.

[0027] A connection structure of prefabricated steel concrete components, that is, a connection structure in which two prefabricated steel concrete components 1 are connected through a connector 2 . The prefabricated steel concrete member 1 is prefabricated by concrete 11 and steel 12, and is in the shape of a square column. The steel 12 adopts I-beam; Cut bolt hole 13. The connector 2 is a pin bolt grouting sleeve type, the main body is two separate U-shaped fasteners 21, and the U-shaped fasteners 21 are welded with shear bolts corresponding to the shear bolt holes 13 reserved at the end of the section steel 22, and reserve a semicircular grouting hole 23. When the two U-shaped fasteners 21 are fastened together, the two semicircular grouting holes 23 form a complete circular grouting hole 3. The ...

Abstract

The invention relates to a connection structure of prefabricated and assembled profile steel concrete components and a construction method of the connection structure. Profile steel end heads are reserved at the two ends of each prefabricated profile steel concrete component, and shear-resisting bolt holes are reserved in the profile steel heads; a connector is of a pin bolt grouting sleeve type and comprises two split U-shaped buckles, shear-resisting bolts corresponding to the shear-resisting bolt holes reserved in the profile steel end heads are welded to the U-shaped buckles, semicircular grouting holes are reserved in the U-shaped buckles, when the two U-shaped buckles are buckled, the two semicircular grouting holes form a circular grouting hole, and the length of the connector is twice the reserved length of the profile steel end heads. According to the connection structure of the prefabricated and assembled profile steel concrete components and the construction method of the connection structure, mechanical connection and grouting connection are combined into a whole, joint connection reliability of profile steel concrete is guaranteed, the construction process is simplified, the requirement for the site construction technological level is lowered, quality defects of a traditional welding process in profile steel connection are avoided, fully fabricated machining and site rapid splicing and assembly of a profile steel concrete structure are achieved, and uniformity and construction quality of a building structure are guaranteed.

Description

technical field [0001] The invention relates to a construction method of a steel concrete structure, in particular to a prefabricated assembled steel concrete member connection structure and a construction method thereof. Background technique [0002] Due to the combination of the respective advantages of steel and concrete, the steel reinforced concrete structure has greatly improved its bearing capacity and seismic performance, and has become the first choice for the composite structure of high-rise buildings. At present, the main connection methods of cast-in-place steel concrete joints are mainly welding and bolt connections, which have high construction strength, high technical requirements, and difficult control of construction quality. [0003] The prefabricated concrete structure system has a relatively high prefabrication rate, and the bearing capacity of the building structure is not lower than that of the cast-in-place structure, which can effectively overcome the...
