Embodiment Construction

[0014] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] Such as figure 1 and figure 2 As shown: the node of the present invention moves the splicing section of the beam-column node of the conventional prefabricated structure outward from the column end, and realizes the transformation of the beam-column node into a frame beam node of precast concrete. The first beam section 1 of the precast concrete frame beam is docked with the second beam section 2 of the precast concrete frame beam, and a horizontal first square steel pipe groove 3 is embedded at the end of the first beam section 1 of the precast concrete frame beam; The end of the second beam section 2 embeds a horizontal second square steel pipe groove 4, and the cross section of the first square steel pipe groove 3 and the second square steel pipe groove 4 is the same; Steel pipe 5; fixed braking device 6 on the top of sliding ...

Abstract

The invention belongs to a prefabricated concrete frame beam node of a prefabricated concrete assembly structure. The technical scheme is: the first beam section of the precast concrete frame beam is docked with the second beam section of the precast concrete frame beam, and a horizontal first square steel pipe groove is embedded at the end of the first beam section of the precast concrete frame beam; The end of the second beam section embeds a horizontal second square steel pipe groove, and the cross section of the first square steel pipe groove and the second square steel pipe groove is the same; a horizontal sliding square steel pipe is set in the second square steel pipe groove; The brake device is fixed on the top of the steel pipe, and a sliding opening for the brake device is set on the top of the second steel pipe groove; the sliding square steel pipe is driven by the brake device to slide in the second square steel pipe groove, and can slide into the first square steel pipe groove ; The surface of the sliding square steel pipe is covered with polytetrafluoroethylene film. The beam-column joints of conventional prefabricated structures are transformed into frame beam joints of precast concrete, thus realizing the anti-seismic concept of "strong joints and weak members".

Description

technical field [0001] The invention belongs to the field of building structure engineering, and in particular relates to a node structure of a prefabricated concrete assembly structure. Background technique [0002] Building industrialization is an important development direction in my country's construction field at present. It can not only effectively shorten the construction period, but also greatly reduce building energy consumption and construction waste, improve building functions and structural performance, and conform to the concept of energy-saving and environmentally friendly building development. Prefabricated prefabricated structure is the main technical means to realize the industrialization of construction. Prefabricated concrete structure has been widely used in Europe, Japan, and Hong Kong. In recent years, prefabricated concrete structure has flourished in the residential field of our country. [0003] At present, my country's prefabricated structures are r...
