Prefabricated steel fiber sludge-made ceramisite concrete wall based on T-shaped groove connection and construction method of prefabricated steel fiber sludge-made ceramisite concrete wall

Abstract

A prefabricated steel fiber sludge-made ceramisite concrete wall based on T-shaped groove connection comprises prefabricated wall plates, cast-in-place connection columns and cast-in-place vertical edge components, wherein the two lateral sides of each prefabricated wall plate are each of a T-shaped groove structure, horizontal and vertical reinforcing steel bars are arranged in the prefabricated wall plates, each cast-in-place column is embedded in the T-shaped groove structures of the corresponding adjacent prefabricated wall plates to connect the prefabricated wall plates, each cast-in-place vertical edge component is provided with a longitudinal protrusion structure matched with the corresponding T-shaped groove structure, the longitudinal protrusion structures are embedded in the T-shaped groove structures on the outer sides of the edge prefabricated wall plates, longitudinal ribs are arranged in the cast-in-place vertical edge components, and reliable anchoring is achieved when the longitudinal ribs and the horizontal reinforcing steel bars in the edge prefabricated wall plates are embedded and spot welding is conducted on the joints one by one. The invention further provides a construction method of the prefabricated steel fiber sludge-made ceramisite concrete wall, and by means of the innovation of materials, the connection mode and the rib matching mode, the wall structure can have the advantages of being capable of lowing energy consumption and reducing vibration, ecological, environmentally friendly, capable of being rapidly constructed, economical and practical.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to an assembled steel fiber sludge-made ceramsite concrete wall based on T-shaped groove connections 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, the m...

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 new ecological concrete wall materials has become an urgent problem to be solved.

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 new type of prefabricated wall reinforcement form with good ductility, uniform energy-dissipating cracks, and excellent cooperative performance with vertical edge components
