A method for assembling upper and lower interior walls and floor slabs

Abstract

The invention provides a method for assembling upper and lower inner walls and floors, comprising the following steps: S1, prefabrication of inner wall shear walls and floor slabs; S2, hoisting and installation: hoisting and positioning the first inner wall shear wall, hoisting the second The first floor and the second floor are respectively placed on the two ends of the top side of the first interior wall shear wall, and then the second interior wall shear wall is hoisted and placed on the top side of the first interior wall shear wall, and the second interior wall shear wall The two ends of the bottom side are respectively pressed on the supporting ribs on the top side of the first floor and the second floor; cavities are formed between the floor and the shear wall of the first interior wall and the shear wall of the second interior wall. Set up longitudinal steel bars, tie bars and anchors; S3, pouring connection: pouring concrete into the cavity to form double-lapped post-casting beams or double-anchored horizontal post-casting strips to connect the floor slab and the interior wall shear wall into one. The on-site construction amount of the connection node is small, the cost is reduced, the construction period is saved, and the integrity and seismic strength of the building are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of prefabricated buildings, and in particular relates to a method for assembling upper and lower inner walls and floor slabs. Background technique [0002] In the prior art, the main form of the connection node between the shear wall and the floor is: the upper and lower shear walls are connected through a grouting sleeve, the laminated floor is placed on the top side of the shear wall, and the laminated floor is poured after placing the longitudinal reinforcement. The cast-in-place layer of the floor slab forms a whole with the laminated floor slab and the shear wall. [0003] In the prior art, the above-mentioned connecting nodes have the following main problems during construction: 1. When the shear wall is hoisted, the steel bars protruding from the bottom are easy to collide and bend, and manual calibration and adjustment are required in the later stage, and the construction efficiency is low; 2. The to...

Problems solved by technology

[0003] In the prior art, the above-mentioned connecting nodes have the following main problems during construction: 1. When the shear wall is hoisted, the steel bars protruding from the bottom are easy to collide and bend, and manual calibration and adjustment are required in the later stage, and the construction efficiency is low; 2. The top of the shear wall The accuracy of the protruding steel bars reserved on the side is difficult to achieve accurately, and the situation of cutting the reserved protruding steel bars during construction often occurs, resulting in waste of steel bar materials and affecting the quality of the project, and it is time-consuming and labor-intensive to accurately align the steel bars and sleeves , it is prone to serious misalignment that leads to the failure of installation, which seriously affects the construction period and construction cost; 3. The grouting quality of sleeve grouting varies, and the grouting density is difficult to uniform and strictly control, and the grouting material density at the grouting anchor connection joint lacks effective detection method, the cost of grouting materials is high, and the cleaning of grouting equipment is time-consuming and complicated; 4. The height of the mortar joints between the shear walls cannot be accurately controlled, and the density and strength are greatly reduced compared with the prefabricated shear wall components, which is an earthquake-resistant weak zone; 5. 1. The cleaning of grouting equipment is time-consuming and complicated; 6. The quality of the slurry is high and the cost is high; 7. The labor cost is high, the construction time is long, and the construction quality is difficult to control
