Problems solved by technology

[0002]The existing concrete building pouring system includes fixedly connected vertical reinforcement, horizontal reinforcement, vertical reinforcement, horizontal reinforcement and wall formwork for on-site construction and on-site installation, Existing problems are: large workload on site, slow construction speed, poor overall rigidity of the wall, and easy displacement of steel bars during the concrete pouring process, making it difficult to guarantee the quality of the project
[0003]In addition, traditional load-bearing walls are heavy and have poor heat and sound insulation performance. When concrete load-bearing walls are poured, the direct connection between the wall and structural columns is too simple, resulting in concrete load-bearing The wall is less resistant to earthquakes
Moreover, after the completion of the construction, the second construction of the external insulation of the external wall will not only increase the cost, but also the life of the completed external insulation layer is not long compared with the life of the building itself, only about 20 years

Embodiment approach 1

[0043] Steel mesh light board sandwich slabs are used as prefabricated wall panels, such as Figure 1-9 As shown, firstly, at the construction site, the pre-embedded connecting steel bars 7 on the load-bearing wall foundation and the concrete foundation beam 6 and the pre-embedded longitudinal steel bars 23 on the structural columns are completed.

[0044] According to the design, install the steel mesh light board sandwich blank 11 between the connecting steel bars pre-embedded in the foundation beam, align, support, and bind firmly (participate image 3 , 4 ). Make preparations for construction, including setting up single-row scaffolding and operating platforms and appropriate environmental protection measures, trial operation of on-site spraying equipment, trial preparation of sprayed concrete, so that the concrete mix ratio, consistency, adhesion, compactness, etc. meet the quality requirements .

Embodiment approach 2

[0055] When multiple prefabricated steel mesh light slab sandwich concrete slabs are used (the cross-section is as follows Figure 11 When the wallboards assembled as shown) are assembled, the construction method adopted is basically the same as that of Embodiment 1, the difference is that the connecting column 4 is poured on site between the adjacent two steel mesh light board sandwich concrete slabs. connection (see Figure 12 ). The steel mesh light slab sandwich concrete slab is prefabricated in a factory, and the prefabrication process is formed by pouring concrete layers 13 on both sides of the steel mesh light slab sandwich slab 11 .

[0056] The thickness of the concrete layer 13 may be 30-50mm, preferably 35mm, 40mm or 50mm. One side of the steel mesh light board sandwich concrete slab can also be prefabricated with an insulation layer.

[0057] During the construction process, the edge of the assembled steel mesh light board sandwich concrete slab (that is, the wa...

Abstract

The invention relates to an industrial construction method for a multistory residence system with a clamp die frame core wall self-bearing structure. The construction of a bearing wall comprises the following steps of: (1) pre-embedding connecting steel bars on a footing of the bearing wall and a concrete foundation beam; (2) arranging a precast wall plate with a light core material between the connecting steel bars of the foundation beam in an aligned mode; (3) respectively arranging the stressed steel bars of a constructional column and a beam, respectively connecting the connecting steel bars of the constructional column and the beam, and arranging the clamp dies of the constructional column and the beam to ensure that the left and right ends and / or the upper end of the wall plate is coated in the clamp die of the constructional column and / or the clamp die of the beam; and (4) spraying concrete onto surfaces on the two sides of the wall plate, and casting the constructional column and the beam in situ. By the construction method, a large number of templates can be saved, the construction speed is obviously increased, the construction period is shortened, cost is reduced, the strength, impact resistance, earthquake resistance and overall performance of the constructed multistory residence system are obviously improved, the dead weight of the system is reduced, and the systemhas good energy conversation, heat insulation and sound insulation effects.

Description

technical field [0001] The invention relates to an industrialized construction method for a self-supporting structure multi-layer residential system with core walls, in particular to a construction method for a multi-layer residential system with a self-supporting structure whose wall is a steel mesh light board sandwich concrete load-bearing wall with a frame. Background technique [0002] The existing concrete building pouring system includes fixedly connected vertical steel bars, horizontal steel bars, vertical steel bars, horizontal steel bars and wall formwork for on-site construction and on-site installation. The existing problems are: large site workload, slow construction speed, The overall rigidity of the wall is poor, and the steel bars are prone to shift during the concrete pouring process, making it difficult to guarantee the quality of the project. [0003] In addition, traditional load-bearing walls are heavy and have poor heat and sound insulation performance....
