Assembled integral concrete frame-shear wall connection structure and its construction method

Abstract

The invention discloses an integrated assembled concrete frame and shear wall connection structure and relates to a construction method thereof. The connection structure comprises upright columns, shear walls and superposed beams which are all prefabricated by concrete. The upright columns and the shear walls are connected end to end horizontally, and n-shaped grooves with side holes are fixedly mounted at the joints of the upright columns and the shear walls. Channel beams penetrate the shear walls longitudinally, and both ends of each channel beam are provided with butt-joint holes. The ends, extending from the tops of the shear walls, of the channel beams, penetrate through holes in the superposed beams which are superposed at the top ends of the shear walls. The shear walls are mounted above the superposed beams, and the butt-joint holes in the channel beams of the upper shear wall and the lower shear wall are connected with connecting bolts through steel plates. The construction method mainly includes steps of hoisting of the upright columns and the shear walls, aligning of the n-shaped grooves, hoisting of the superposed beams, connecting of the ends of the upper shear wall and the lower shear and the like. The connection structure has the advantages of convenience in hoisting and butting joint, quick mounting and the like.

Description

technical field [0001] The invention relates to a prefabricated assembled concrete structure and a construction method thereof, in particular to an assembled integral concrete frame-shear wall connection structure and a construction method thereof. Background technique [0002] As a structural form in line with industrial production methods, prefabricated concrete structures have the advantages of fast construction speed, low labor intensity, less noise pollution and wet work, and easy control of product quality. The construction method of prefabricated assembly can effectively save resources and energy, improve the utilization rate of materials in realizing building energy saving and structural performance, overcome the restrictions of construction site and environmental conditions on site construction, reduce the number of on-site construction labor force, and reduce construction waste And the adverse impact of construction on the environment, improve building function and...

Problems solved by technology

[0004] At present, in the actual construction of the assembled frame-shear wall structure, there are still many construction difficulties in the connection structure of the upper and lower shear wall structures. Chinese patent document CN102808465A discloses a connection structure of an assembled integral concrete frame-shear wall Compared with the construction method, the steel bars protruding from the end of the prefabricated parts are connected by using the steel bar sleeve. It is difficult to align the upper and lower layers of steel bars one by one, and the number of steel bar sleeves used in the construction is large, so the operation of aligning and connecting one by one is quite time-consuming
