Assembly column-beam frame and sleeve structure thereof

Abstract

The invention discloses an assembly column-beam frame and a sleeve structure thereof, and belongs to the field of prefabricated assembly concrete structure engineering. The frame and the sleeve structure comprise a prefabricated stand column, a prefabricated cross beam and a prefabricated longitudinal beam; four positioning columns are arranged on the square end face of the stand column and are divided into side columns and core columns; the rectangular end faces of the cross beam and the longitudinal beam are divided into four equal parts from top to bottom, one positioning piece is generated outwards separately, namely, a first positioning piece, a second positioning piece, a third positioning piece and a fourth positioning piece, four evenly-distributed positioning holes are formed in each positioning piece, and the positions and the sizes of the positioning holes are matched with the positions and the sizes of the core columns; and beam sleeper area position are delimited on the parts, where the positioning pieces and the beam body of the cross beam or the longitudinal beam are jointed, of the edge of the beam body. The assembly column-beam frame and the sleeve structure thereof have the beneficial effects that the structure is simple, and only three prefabricated structural members are needed; and the matching is compact, assembly is firm, screws or welding are not needed during assembly, secondary pouring can be avoided, construction is convenient, the construction period can be effectively shortened and the ductility and the bearing capacity of a joint area are improved.

Description

technical field [0001] The invention belongs to the field of prefabricated assembled concrete structure engineering, in particular to an assembled column-beam frame and a nested structure thereof. Background technique [0002] The frame structure is the most widely used structure in the construction industry. The frame structure can work as a whole. The reliable connection between the frame column and the frame beam is very critical. The traditional concrete structure is due to the concrete cast-in-place, and the stressed steel bars in the node area are continuously arranged. As long as the configuration is reasonable Generally, there will be no damage to the connection between components, but in the actual construction process of precast concrete structures, the construction positioning of the joints of precast components is not easy, thus reducing the construction speed and efficiency; for precast concrete structures, components Whether the quality of the connection can be...

Problems solved by technology

[0004] However, this structure still has high requirements on the joints, and the process is cumbersome. The reserved holes and reserved steel bars still need to be bound and poured on site. There are still problems in the combination with prefabricated parts, and the cost is high, which is not conducive to the current housing industry in my country. development of globalization and construction industrialization
