Prefabricated polypropylene fiber sludge ceramsite concrete wall based on rough surface connection and its construction method

Abstract

The present invention is based on the assembled polypropylene fiber sludge ceramsite concrete wall body connected by rough surfaces, including: prefabricated wall panels, the left and right sides of which are rough surfaces, built-in horizontal steel bars and vertical steel bars; cast-in-place vertical edge components and existing The poured connection column is connected with the prefabricated wallboard through the rough surface, and the longitudinal reinforcement is built in, and the vertical reinforcement and the horizontal reinforcement are nested, and the joints are spot welded to achieve reliable anchoring, forming a horizontal connection structure; the sleeve with concave and convex grooves The upper end of the vertical steel bar is inserted into the sleeve, and the grouting material is injected to harden to realize the reliable connection between the vertical steel bar and the sleeve, and the polypropylene fiber sludge ceramsite concrete is poured to form a vertical connection structure. The prefabricated wall panels are made of It is made of polypropylene fiber sludge ceramsite concrete. The invention also provides a construction method for the wall. The invention makes the wall more durable than the traditional assembled wall through innovations in materials, connection methods, and reinforcement forms. It has the advantages of energy consumption and shock absorption, eco-environmental protection, rapid construction, economical and practical.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a prefabricated polypropylene fiber sludge ceramsite concrete wall based on rough surface connection and a construction method thereof. Background technique [0002] The prefabricated concrete structure meets the social requirements of resource conservation and environmental friendliness put forward in my country's "Twelfth Five-Year Plan", and is one of the effective ways to realize building energy conservation, emission reduction and housing industrialization. In recent years, the country's policy guidance and preferential policies for prefabricated housing have been introduced one after another. The prefabricated integral shear wall structure has been widely used in high-rise residential structures due to its good integrity, high rigidity, and high bearing capacity. At present, the development of prefabricated walls is facing many problems. On the one hand, th...

Problems solved by technology

At present, the development of prefabricated walls is facing many problems. On the one hand, the materials used in the walls are traditional concrete materials, which makes my country's energy and raw material consumption too large. Therefore, finding ecological concrete wall materials has become an urgent problem to be solved now.

On the other hand, the connection method of the traditional prefabricated shear wall structure needs to be further improved. The current connection method requires high prefabrication precision of components and takes a long time to install the holes, which greatly delays the construction period and increases the project cost. Therefore, it is necessary to The connection structure used in traditional prefabricated shear walls is improved, and a prefabricated wall connection structure with simple structure, reasonable design, convenient construction, low investment cost and good use effect is proposed

Finally, the structural integrity of the traditional prefabricated shear wall is poor, and the structural system lacks multiple fortification anti-seismic mechanisms. The failure of a single shear wall is mainly shear brittleness, which is difficult to meet the ductility design requirements of the structure. Optimizing and innovating the reinforcement form of the force wall, and proposing a prefabricated wall reinforcement form with good ductility, uniform energy-dissipating cracks, and excellent cooperative performance with cast-in-place vertical edge components
