Description

Technical Field

[0001] The present invention relates to the field of molds, and particularly to a mold for precast concrete composite slabs. Background Art

[0002] In industries such as metallurgy, cement production, aerospace, etc., it is necessary to build kilns and diversion parts, and their stressed parts are generally made of steel or cast-in-place reinforced concrete, and the inner surface of the steel and cast-in-place reinforced concrete is a concrete lining layer for preventing ablation. For the construction method of the concrete lining layer for preventing ablation, the concrete lining layer for preventing ablation is constructed after the corresponding structural parts are completed, and the construction period of this construction method is long. By prefabricating the concrete lining layer for preventing ablation composite slab and using it as a formwork when generating the structural part concrete, a composite slab system can be formed, which can effectively improve the generation efficiency. The external shape and internal steel bar mesh structure of the precast part of the concrete lining layer for preventing ablation are relatively complex. To ensure the production and forming quality, a special casting mold needs to be designed for the casting forming method. Summary of the Invention

[0003] The present invention aims to provide a mold for precast concrete composite slabs, which solves the problem that there is no precast mold for the concrete lining layer for preventing ablation in the prior art.

[0004] To achieve the above object, the technical solution of the present invention is as follows: A mold for precast concrete composite slabs, where each component is assembled into a mold box through bolts, components such as steel bars inside the composite slab are assembled, and then the assembled internal steel bar mesh of the composite slab is supported in the center of the mold through supporting pieces, ensuring the accurate positioning of each component inside the composite slab.

[0005] Further, each component of the mold includes a side wall plate for preventing ablation, a joint template for the upper convex part, a lower joint template for the lower concave part, a middle joint template for the lower concave part, an upper joint template for the lower concave part, a joint template for the left concave part, a joint template for the left convex part, a joint template for the right concave part, a joint template for the right convex part, a supporting plate, and a supporting piece.

[0006] Further, the operation of supporting the assembled internal steel bar mesh of the composite slab in the center of the mold through supporting pieces is to wrap each group of supporting plates around the corresponding steel sleeve from both sides, then embed the supporting pieces into the steel bar mesh connectors, and support the steel bar mesh on the supporting plates.

[0007] Compared with the prior art, the beneficial effects of this solution are as follows:

[0008] This solution ensures the accurate positioning of components such as the steel bar mesh in the mold for the ablation-proof composite slab. During the casting and forming process of the ablation-proof composite slab, components such as the internal steel bar mesh are suspended inside, ensuring that the distance between the steel bar mesh and the fire-facing surface meets the design requirements, and avoiding local defects on the fire-facing surface caused by using traditional pads, thereby affecting the ablation-proof effect.
