Prefabricated concrete wallboard and wallboard structural system constructed through prefabricated concrete wallboards and provided with hidden frame

Abstract

The invention discloses a prefabricated concrete wallboard and a wallboard structural system constructed through prefabricated concrete wallboards and provided with a hidden frame. A reinforcing mesh in the wallboard comprises a hidden supporting reinforcing mesh body. The hidden frame of the structural system constructed through the wallboards is formed by casting concrete at joints of a floor and the wallboards in place, and an inner frame of a whole building is formed. Prefabricated concrete hollow walls, boards and beams are connected into a whole, the space structural system with good overall work performance and lateral load resisting performance is formed, effective connection of stressed complex positions can be guaranteed, and the problem that the overall performance and the anti-seismic property of a prefabricated building are poor can be solved. Vertical prestress is applied to the walls of the high-rise building in batches to enhance the stress performance of the wall structure, hidden supports are arranged in the prefabricated walls to form a hidden frame space system with the hidden supports, and the requirement for seismic fortification is improved. The wallboard structural system has the remarkable beneficial effects of being high in assembly rate, good in integrity and anti-seismic property, excellent in waterproofness and the like, and can be suitable for building of multi-storey house buildings and high-rise house buildings.

Description

Technical field [0001] The invention belongs to the technical field of construction of prefabricated prefabricated concrete houses in civil engineering, and specifically relates to a prefabricated concrete wall panel and a wall panel structure system with a dark frame constructed thereof. Background technique [0002] The beam-column components of traditional reinforced concrete frame structure houses are often cast concrete after the formwork is supported on the construction site. The components are reliable in connection, integrity and seismic performance are good, but the construction period is long and the management is complicated. The use of prefabricated assembly methods in housing construction represents an advanced development direction. [0003] At present, prefabricated frame buildings in our country often use small and medium-sized component factory prefabrication, such as prefabricated beam and column components. Its advantages are obvious, but there are also some prob...

Problems solved by technology

[0003] At present, my country's prefabricated frame buildings are often prefabricated by small and medium-sized component factories, such as prefabricated beam-column components, etc., which have obvious advantages, but there are also some problems. Compared with the cast-in-place process, too many assembled connection parts lead to multiple weaknesses There is a certain degree of difficulty in quality control

At present, the prefabricated parts are usually assembled in places where the structural forces are complex and weak, such as beam-column
