Problems solved by technology

In the commonly used prefabricated structures, the connection between prefabricated beams and prefabricated columns is concentrated in the core area of ​​the beam-column intersection, and the core area of ​​the beam-column intersection is a complex part of the force. The handover of multiple components will inevitably increase its complexity and affect the frame structure. Wholeness
In addition, there are also few cases where the beam connection node is set outside the column, the column is prefabricated as a whole, and the prefabricated steel members are used to protrude from the column edge to connect with the prefabricated beam; The penetration of the column increases the difficulty of production; at the same time, the protruding steel members of the column will cause the column surface to be uneven, thus increasing the difficulty of transportation and storage of the prefabricated column

Abstract

The invention discloses a prefabricated beam-column connection in prefabricated concrete buildings, comprising a prefabricated column, prefabricated beams and a joint connecting member. The prefabricated column is provided with through holes. Beam vertical bars are embedded in the prefabricated beams in advance. The joint connecting member comprises rebars, casings, hoops and cast-in-place concrete. The rebars extend through the through holes to be connected with the beam vertical bars through the casings and are fixed via the hoops. The cast-in-place concrete is poured in a beam-column connection area. A construction method of the prefabricated beam-column connection includes: producing the prefabricated column and the prefabricated beams; lifting the prefabricated column in place, and extending the rebars through the through holes; grouting the through holes; mounting the hoops temporarily on rebars extending out a connection face of a column connecting part; lifting the prefabricated beams in place, and connecting the rebars and the beam vertical bars through the casings; fixing the hoops at intervals to the rebars, casings and beam vertical bars connected with one another; and pouring the cast-in-place concrete. The prefabricated beam-column connection has excellent mechanical properties, is convenient to produce, store, transport and construct and is easy to industrially produce, construction period is shorter, and cost is saved.

Description

technical field [0001] The invention relates to the field of structural engineering, in particular to a prefabricated beam-column connection node in an assembled concrete building and a construction method thereof. Background technique [0002] With the continuous and rapid development of my country's economy and the acceleration of urbanization, in order to achieve sustainable development of urban and rural construction, it is proposed to change the mode of urban and rural construction, promote the transformation and upgrading of the construction industry, and vigorously promote "construction industrialization" has become one of the top tasks. [0003] One of the important carriers of construction industrialization is the prefabricated concrete structure, and the prefabricated beam-column connection technology is the key technology of the prefabricated concrete structure. In the commonly used prefabricated structures, the connection between prefabricated beams and prefabric...
