Prefabricated polypropylene fiber sludge ceramsite concrete wall and its construction method based on horse teeth connection

Abstract

The present invention is based on the assembled polypropylene fiber sludge ceramsite concrete wall body connected by horse-tooth bars, including: prefabricated wall panels, the left and right sides of which are provided with horse-tooth bar structures, built-in horizontal steel bars and vertical steel bars; cast-in-place connecting columns And the cast-in-place vertical edge components are connected with the prefabricated wall panels through the occlusion structure of the horse teeth, and the built-in longitudinal bars nested with the horizontal steel bars form the connection structure of the horizontal prefabricated wall panels; the pre-embedded welding plates are embedded in the prefabricated wall panels The bottom surface is connected to the welding plate arranged on the top surface of the hidden beam in the vertical direction by welding; wherein the prefabricated wallboard is made of polypropylene fiber sludge ceramsite concrete, and the present invention also provides the connection based on horse-toothed The construction method of the prefabricated polypropylene fiber sludge ceramsite concrete wall, through the innovation of materials, connection methods and reinforcement forms, the present invention makes the wall structure more energy-consuming, shock-absorbing and eco-friendly than traditional prefabricated walls. Environmental protection, rapid construction, economical and practical advantages.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to an assembled polypropylene fiber sludge ceramsite concrete wall based on a horse-tooth 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, 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 prefabricated wall reinforcement form with good ductility, uniform energy-dissipating cracks, and excellent cooperative performance with vertical edge components
