A pre-construction formwork with concrete reinforcement as the main raw material

Abstract

The invention discloses a pre-building material formwork with concrete reinforcement as a main raw material. By additionally arranging triangular angle irons, square groove steel, assisting iron wiresand iron wire pulling rods and combined with mixed cement mortar, fiber cloth, tying steel wires and fiber ropes, the whole structure of the formwork is completed, particularly, a structure that thetriangular angle irons are connected side by side is completed, a pre-building material is wrapped with the structure, the triangular angle irons are in 'V' shapes, and penetrating holes formed in thetwo walls of the triangular angle irons have deformation spaces, for example, an elastic bearing body, the whole structural property of the formwork is changed through the toughness and the rigidityof the elastic bearing body. The assisting iron wires and the iron wire pulling rods additionally arranged on the upper surface of the formwork are fused in concrete, the bearing capacity and the toughness of the formwork are transversely improved, and meanwhile due to tensile force generated when the assisting iron wires and the iron wire pulling rods are fused in the concrete, the anti-falling-off effect is excellent. The upper fiber cloth and the lower fiber cloth and a body steel frame of the formwork are tied and connected together according to the setting structure through the tying steel wires or the fiber ropes, and the produced formwork is more stable and easier to carry.

Description

technical field [0001] The invention belongs to the technical field of pre-building material formwork, in particular to a pre-building material formwork with concrete as the main material. Background technique [0002] Today, construction engineering technologies such as automation technology and lifting technology are becoming more mature and powerful, which has accelerated the speed of construction. Among them, there are various kinds of preformed building materials developed in the industry and can be used, involving a wide range of levels, basically able to Provide preformed building materials with a molding degree that is very close to the construction requirements for various types of building construction, as well as mold building materials for auxiliary construction. By mass-producing the required preformed building materials and mold building materials for auxiliary construction in advance, and then transporting them to the construction site for direct use, Greatly ...

Problems solved by technology

However, its structural design is unreasonable. The dry-mixed cement mortar is soft and easy to disperse before it is watered and fixed into the shape of the formwork. When the mold is finalized, the water added will carry the dry-mixed cement mortar to seep out, and the structural formwork is built. Insufficient bearing capacity of the mold

The more serious problem is that because only the inner wall of the mold (that is, the fiber cloth) is bonded to the outermost layer of the poured concrete, and the degree of adhesion between the fiber cloth itself and the concrete is not high, the mold of this kind of structure will be damaged after a long time or after a long time. Vibration, the mold of this structure is easy to separate from the wall, beam or concrete reinforcement formed by pouring
