Integrated formwork-removal-free building system and construction method thereof

Abstract

The invention provides an integrated formwork-removal-free building system and a construction method thereof, and belongs to the technical field of fabricated buildings. The system comprises a floor support plate, a shear wall, a structural column and a structural beam. A bottom face of the floor support plate, two side faces of the shear wall, side faces of a periphery of the structural column and side faces and a bottom face of the structural beam are all of an integrated formwork-removal-free face structure. The integrated formwork-removal-free face structure comprises a removal-free formwork, a plurality of first connecting strips and a plurality of trusses sequentially arranged from outside to inside; the trusses on the floor support plate, the structural column and the structural beam are all connected with structural main reinforcements; two sets of second connecting strips and a heat preservation plate are further arranged between two side faces of the shear wall; and the floor support plate, the shear wall, the structural column and the removal-free formwork of the structural beam are all spliced in a sealed mode. The construction method is used for constructing the system. The whole structure of the integrated formwork-removal-free building system belongs to a fabricated structure, the reinforced concrete structure can be continuously poured, such that the whole structure is integrated, the structural strength can be guaranteed, construction can be facilitated, and forming quality is good.

Description

technical field [0001] The invention belongs to the technical field of prefabricated buildings, and more specifically relates to an integrated formwork-free building system and a construction method. Background technique [0002] The frame shear structure is the frame shear wall structure. This structure is to arrange a certain number of shear walls in the frame structure to form a flexible and free use space to meet the requirements of different building functions. At the same time, there are enough shear walls. Considerable lateral stiffness. The large lateral stiffness of the shear wall means that it has a strong ability to resist deformation under the action of horizontal loads (wind loads and horizontal seismic forces). [0003] Although the related technologies of prefabricated buildings have developed rapidly in recent years, and the requirements for building assembly rates in various regions are getting higher and higher, but because the existing prefabricated build...

Problems solved by technology

[0003] Although the related technologies of prefabricated buildings have developed rapidly in recent years, and the requirements for building assembly rates in various regions are getting higher and higher, but because the existing prefabricated building components are usually connected by connectors or post-cast structures, the connection Strength and seismic performance are generally lower than cast-in-place structures, so the frame-shear structures used in high-rise buildings are still cast-in-place structures

[0004] The frame-shear structure adopts a cast-in-place structure. On the one hand, it is difficult to increase the building assembly rate after reaching a certain level, and the cast-in-place structure needs to set up formwork, which makes the construction more complicated and the efficiency is relatively low; on the other hand, the shear force of the frame-shear structure When the wall is used as an external wall, since the current cast-in-place shear wall is difficult to install an insulation structure inside, it is necessary to hang insulation materials for insulation, otherwise the insulation performance is difficult to meet the standard, but there is a large fire hazard in high-rise buildings at present. It is gradually restricted in various places, and because of the large size of the shear wall, all used as interior walls will occupy a large amount of internal space of the building, which limits the use of frame-shear structures
