Abstract

The invention discloses an assembled monolithic concrete frame structure system and a frame shear structure system formed by the assembled monolithic concrete frame structure system. The assembled monolithic concrete frame structure system comprises precast columns, precast beams and precast floors, wherein the precast beams and the precast columns are connected to form a frame structure; the precast floors are arranged on the frame structure in an overlapping manner and are connected with the precast beams. The assembled monolithic concrete frame shear structure system comprises the assembled monolithic concrete frame structure system and precast sheer walls. According to the assembled monolithic concrete frame structure system and the frame shear structure system formed by the assembled monolithic concrete frame structure system, building materials can be saved, the structure self-weight is reduced, the construction speed is increased, the production efficiency is improved, the precast sheer wall bodies and seam construction are improved, the appearance and development of inclined cracks of the precast sheer wall bodies are reduced, and the anti-seismic working performance of the precast concrete frame structure system and the frame shear structure system formed by the precast concrete frame structure system is effectively enhanced.

Description

technical field [0001] The invention belongs to the technical field of assembled concrete buildings, and in particular relates to an assembled integral concrete frame structure system and a frame-shear structure system formed therefrom. Background technique [0002] Prefabricated concrete building is an important way of building industrialization. It has many advantages such as fast construction speed, short construction period, high production efficiency, good product quality, safety and environmental protection, effective cost reduction, material consumption and construction process. Prefabricated concrete frame structure and frame-shear structure refer to the prefabrication of columns, beams, shear walls, floors and other components in the processing plant or construction site, and the scattered prefabricated components are connected into a whole through mechanical hoisting and certain connection means. formed structure. This structure has the advantages of good componen...

AI Technical Summary

Problems solved by technology

[0003] However, the existing prefabricated concrete frame and frame-shear structure buildings have many deficiencies that limit the promotion and application of this type of structure.

For example, the prefabricated components are all solid concrete rods, the structure has a large dead weight, wastes building materials, and has higher requirements for construction machinery and hoisting equipment; the beam-column joints do not transmit force directly, and the reliability is poor, resulting in earthquake resistance and The overall performance cannot be fully guaranteed; in order to increase the seismic performance of the structure, many nodes are set as cast-in-place nodes. There are horizontal and vertical steel bars, which cannot effectively prevent the occurrence and development of cross-slanted cracks along the principal stress direction during use, resulting in the degradation of the stiffness of the shear wall structure and the reduction of bearing capacity, and even affect high-rise buildings in severe cases safe use, etc.
