Problems solved by technology

[0002] At present, my country's construction is still mainly cast-in-place on construction sites, and there are problems such as low construction efficiency, large resource consumption, large construction noise, large environmental pollution, low professionalism of construction teams, poor construction accuracy, and high user complaint rate. There is a big gap in building construction technology
[0003] my country's prefabricated buildings have just started and are advancing rapidly. Many technical issues are still in the exploratory stage. Some theoretically solved problems cannot be achieved in actual construction, and there are many hidden dangers that affect structural safety.
In particular, the existing prefabricated shear wall construction adopts the method of prefabricating the entire shear wall body in the factory and assembling it on site. The integrity of the node connection is poor, the connection operation of the steel bar is troublesome, the reliability of the steel bar connection is low, and the bearing capacity is unreliable. There are many security risks

Embodiment 1

[0051] Such as figure 1 and figure 2 As shown, this embodiment includes the following steps:

[0052] Step 1, prefabricated wall panel 5 and reinforcement frame 19, prefabricated reinforced concrete wall panel 5 in factory, and prefabricated reinforcement frame 19;

[0053] Step 2, hoisting wallboard 5 and reinforcing bar frame 19, hoisting two relatively arranged wallboards 5 at the position of the shear wall to be constructed, and hoisting the reinforcing bar frame 19 positioned between two wallboards 5. The hoisting sequence of the wall panels 5 and the reinforcement frame 19 is not limited, it may be that two relatively arranged wall panels 5 are hoisted first, and the wall panels 5 are fixed, and then the reinforcement frame 19 is hoisted between the two wall panels 5 ; Also can be hoisting steel frame 19 earlier, then hoisting wallboard 5 again.

[0054] Step 4, fixing the sealing plate 20, fixing the sealing plate 20 between the two wall panels 5, the sealing plate ...

Embodiment 2

[0073] This embodiment includes the following steps:

[0074] Step 1, factory production, including the following operations,

[0075] (1) The factory produces welded steel mesh for the countertop, and welds and fixes the tie-bar connectors on the steel mesh, pours fine stone concrete, maintains it, and completes the prefabrication of the single-piece wall panel. The wallboard is not only the surface structure of the permanent shear wall, but also replaces the formwork during the construction process.

[0076] For the interior wall panels with standard floor heights, they can also be produced according to the wall height such as 2,78 meters wide, and the fixed length is 9 meters or 6 meters; it can be cut into a single reinforced concrete sheet according to the actual size of the single wall.

[0077] For external wall panels, it is a reinforced concrete composite panel that combines the outer concrete of the shear wall, steel mesh, tie bar connectors, insulation layer, prote...

Abstract

The invention discloses an integral pouring and quick building process of a prefabricated shear wall. The construction of the shear wall can be completed through precasting a steel reinforcement frameand a reinforced concrete wallboard, lifting the wallboard and the stele reinforcement frame on a building site, then closing a lateral opening of the wallboard and pouring concrete, wherein the wallboard is precast into a reinforced concrete structure in a factory, and not only can serve as a bearing carrier of the shear wall, but also can serve as a template of the shear wall; the template doesnot need to be dismantled after the concrete is poured; the construction cost and the material cost are vastly decreased; the construction efficiency of the shear wall is improved. The precast steelreinforcement frame is arranged between two wallboards to strengthen the shear wall; the procedures of site construction are further reduced; the operation of the site construction is simpler; the construction efficiency is higher. Moreover, the concrete is poured on the spot in a sandwich layer between the two wallboards; the integrity of the node of the shear wall and a bottom to-be-connected position is ensured, and the connection of the node is more stable, more reliable and safer.
