The invention content is as follows:
the invention aims to provide a cast-in-place concrete wall body combining truss reinforcing steel bars and steel plates and a construction method, which solve the problems that the existing assembly type prefabricated wall body component is heavy in weight and high in on-site hoisting cost, and the wall body component has potential safety hazards of insufficient grouting and the like in a sleeve connection mode; the more installation of the vertical connection hole of component is to the problem that the hole degree of difficulty is big.
The above purpose is realized by the following technical scheme:
the utility model provides a cast in situ concrete wall body of combination truss reinforcing bar and steel sheet, its constitution includes: truss reinforcing steel bar and steel plate combination and cast-in-place concrete wall body, truss reinforcing steel bar and steel plate combination constitute by truss reinforcing steel bar and steel plate, two the steel plate between install the truss reinforcing steel bar, and truss reinforcing steel bar and steel plate welded fastening, the truss reinforcing steel bar constitute by last quarter reinforcing steel bar, last quarter reinforcing steel bar and web member reinforcing steel bar, the steel plate lateral surface be coarse surface, cast-in-place concrete wall body constitute by ligature longitudinal reinforcement, horizontal reinforcement and lacing wire in truss reinforcing steel bar and steel plate combination and form the framework of steel reinforcement, and in truss reinforcing steel bar and steel plate combination pour the concrete and form cast-in-place concrete wall body.
The cast-in-place concrete wall combining the truss reinforcing steel bars and the steel plates is characterized in that the rough surface is convex or concave, and the convex or concave is in a straight shape or a circular shape or other shapes.
The cast-in-place concrete wall body combining the truss steel bars and the steel plates is characterized in that the truss steel bar steel plates are combined into a T-shaped or L-shaped or straight-line-shaped structure.
The cast-in-place concrete wall body combining the truss reinforcing steel bars and the steel plates comprises the following steps:
after the truss steel bars are processed, the truss steel bars are arranged according to a T shape, an L shape, a straight shape or other shapes, the steel plates with rough surfaces are connected with the upper chord steel bars and the lower chord steel bars of the truss steel bars in a welding mode, the size and the flatness of the combination of the truss steel bar and the steel plates are adjusted, horizontal steel bars, longitudinal steel bars and tie bars are bound in the combination, finished products are reinforced for later use, wall lines and installation control lines are popped out from the installation working face, the finished products are hoisted to the installation working face, supports are arranged, the positions and the verticality of the finished products are adjusted, cast-in-place concrete is poured in the finished products, and the construction of the cast-in-place concrete wall body combining the truss steel bars and the steel plates is completed.
The invention has the beneficial effects that:
1. according to the invention, on the premise of not erecting a cast-in-place wall template and binding reinforcing steel bars in the wall, concrete pouring work is carried out only on the construction site, the construction processes of binding the reinforcing steel bars, erecting the formwork and pouring the concrete in the traditional building construction are changed, key line procedures are reduced, the construction period is shortened, the construction progress is accelerated, the advanced delivery and use are realized, a large amount of construction cost is saved, and the economic benefit and the social benefit of implementation projects are improved.
2. The invention replaces the prefabricated reinforced concrete wall body member, and solves the problems of high type selection of the on-site hoisting machinery and high purchase or lease cost of the hoisting machinery due to heavy weight of the prefabricated member. The problem of the vertical connection of current prefabricated component adopt the sleeve that the muffjoint brought with high costs, to hole installation difficulty and grout quality to be difficult to guarantee is solved. The problem of new and old concrete joint cracking caused by the fact that prefabricated components are prefabricated in a factory and connection nodes are poured in situ is solved.
3. The invention can realize the field installation of factory batch production, realizes the construction of an assembly mode, has neat construction field, reduces construction waste and reduces the environmental pollution caused by the traditional construction; reduce on-spot manual work, avoid litter worker phenomenon, reduce the cost of labor, realize that the concrete pours simultaneously, structural integrity is good.
