Single-row reinforcement sheet with fiber concrete on frames and common concrete in middle and manufacturing method

Abstract

The invention provides a single-row reinforcement sheet with fiber concrete on frames and common concrete in the middle and a manufacturing method, and belongs to the field of manufacturing of concrete slabs in building structure engineering. Fibers meeting different structure requirements are adopted by the fiber concrete according to design requirements, the common concrete is adopted except the frames of the sheet, the strength and diameter of reinforcement meshes arranged on the frames are greater than those of steel bars of an orthogonal steel wire mesh in the middle, and therefore the sheet with the fiber concrete on the frames and the common concrete in the middle is formed. The steel bars are arranged in hooks formed by bending steel wires extending from the four sides of the steel wire mesh, and a complete reinforced mesh is precast. The fiber concrete is poured on the periphery of the sheet, and the common concrete is poured in the sheet. The initial cracking resistance of the concrete sheet is improved, shrinkage plastic cracks at the early stage of the concrete are reduced, and the single-row reinforcement sheet has great significance to solution of the prevalent problems that current concrete sheets are low in sheet frame strength, prone to collision loss and high in manufacturing cost. The sheet is easy to construct, the using number of formworks and supports in construction can be greatly reduced, operation intensity of workers is lowered, and the amount of labor used in engineering is reduced.

Description

Technical field: [0001] The invention belongs to the technical field of concrete slab production in building structure engineering, and in particular relates to an ordinary concrete single-row reinforced thin slab in the middle of frame fiber concrete and a production method thereof. Background technique: [0002] Since the invention of cement, concrete materials have developed rapidly and become an indispensable building material in construction projects. Compared with other building materials, concrete materials have the advantages of wide source of raw materials, low production cost, simple preparation, high compressive strength, good fire resistance and plasticity, and relatively simple construction. However, as a multi-component mixed material, concrete has defects such as early initial crack development, low tensile strength, high brittleness, and poor impermeability. Research has proved that there is a good grip between steel and concrete, and the addition of steel c...
