Embodiment Construction
[0029]The double-sided cast-in-place construction method of composite wall panel concrete in CL structural system includes the following steps: (1) Fabrication and blanking of CL grid panels: the node form of CL grid panels is that one side of the outer wall has anchor wires on one side of the CL grid panels , with cold-drawn steel wires on the other side, double anchor wires on one side of the CL grid plate on the 2 sides of the inner wall, and cold-drawn steel wires on the other side; when cutting the material, it is cut according to the design size, and the size of the polystyrene plate is not required to be deducted; (2) Since the pouring thickness of the concrete on both sides of the polystyrene board is different, that is, the outer wall is thicker than the inner wall, the self-compacting fine stone concrete flows quickly on the outer wall side, causing the polystyrene board to be extruded and shifted toward the inner wall side. Directly prefabricate the square cone concr...

Abstract
The present invention relates to the building construction technique filed, concretely to a construction method for two-side in-place-casting the CL structure system composite wall plate concrete, the invention settles the problems of high construction and transportation cost, large installing difficulty, weak wholeness and hard guaranteeing the construction quality caused by that the existing CL structure system composite wall plate adopts single-side prefabricating and single-side casing-in-place, and the method comprises the steps of CL rack board manufacturing and baiting; directly prefabricating the square pyramid concrete cushion block on the polystyrene board of the inner wall side CL rack board; CL rack board installing and tying to the steel bar of the edge component; arranging the formwork of the wall; prefabricating the rectangular concrete cushion block, before the closing of the formwork inserting a rectangular concrete block with position corresponding with the square pyramid concrete cushion block at the side of the CL rack board of the exterior wall side, and the concrete of inner wall and exterior wall is simultaneously casted. The invention has the advantages of simplifying the construction working procedure, reducing the quality control point, guaranteeing the quality, shortening the construction time for a large scale, increasing the economic benefit, and the wall concrete has the advantages of compactness, good whole structural property and smooth external appearance.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a double-sided cast-in-place construction method for composite wall panel concrete of a CL structure system. Background technique [0002] CL structure system (Construction light structure system) is a composite reinforced concrete shear wall structure system, which is composed of CL composite wall panels and edge components (reinforced concrete reinforcement components around the CL composite wall panels, such as hidden columns and hidden beams) , A cast-in-place integral structural system formed by connecting cast-in-place floors, and a small number of L-shaped, T-shaped, and rectangular small wall piers are partially set. The CL structure system is a new type of building structure system, which has the advantages of light weight, earthquake resistance, energy saving and heat preservation, and a wide range of applications. The CL structure system does not use clay...
