Problems solved by technology

However, for a long time, in the construction of cast-in-place buildings, there have been extensive on-site wet operations, large labor input, high labor intensity, poor working environment, large investment in formwork and scaffolding, low turnover utilization rate, and low degree of mechanized construction. Hidden dangers of construction safety and frequent accidents, relatively low work efficiency, and thorny problems such as a large amount of dust, noise pollution, and construction waste on the construction site

Embodiment

[0017] Such as figure 1 As shown, considering that in the RC frame-shear wall structure, the coupling beam is the bridge connecting the shear wall and the frame, and the stiffness of the shear wall is much larger than that of the frame, the coupling beam actually acts to transfer the seismic force on the wall The bridging effect smoothly transmitted to the frame, the damage of the coupling beam is generally more serious in actual earthquakes. In view of the importance of the coupling beam, in the fully assembled RC frame-shear wall structure;

[0018] The stirrup at the post-casting zone of the composite beam on the outer side of the shear wall needs to be densified to ensure that the shear strength of the beam end is large enough to prevent damage in the earthquake. The connection between the shear wall and the composite beam in the fully assembled RC frame-shear wall structure refers to the connection between the frame column and the composite beam. A wall beam is set on t...

Abstract

The invention discloses a connection method for prefabricated shear wall-laminated beams in an assembled type RC frame-shear structure. During formal assembling, the shear wall is first assembled for supporting, column nodes of the shear wall are assembled, a wall beam is arranged on the shear wall, longitudinal reinforcements are arranged above the shear wall, and a full grouting sleeve and beam stirrups are arranged on the longitudinal reinforcements at the nodes of the shear wall after the supporting is completed; then, laminated beams provided with upper longitudinal reinforcements are hoisted, the laminated beams are leveled and supported, and the preset full grouting sleeve is screwed, so that the connected longitudinal reinforcements are evenly distributed inside the full grouting sleeve; and after connection is completed, the stirrups are strapped, a rear pouring concrete is poured, and maintenance is carried out. According to the connection method for the prefabricated shear wall-laminated beams in the assembled type RC frame-shear structure, whole construction is simple and convenient, connection is firm, the anti-seismic performance is good, the construction cost is reduced, and the construction period is short.

Description

technical field [0001] The invention belongs to the field of building structure connection methods, and in particular relates to a connection method of prefabricated shear walls and composite beams in an assembled RC frame-shear structure. Background technique [0002] Traditional cast-in-place buildings refer to buildings constructed on the construction site by binding steel bars, supporting formwork, and pouring concrete. For a long period of time in the past, cast-in-place construction has played a positive role in absorbing the surplus rural labor force in our country and solving the employment of personnel. At present, the cast-in-place method still occupies the absolute mainstream in my country's construction. However, for a long time, in the construction of cast-in-place buildings, there have been extensive on-site wet operations, large labor input, high labor intensity, poor working environment, large investment in formwork and scaffolding, low turnover utilization r...
