Prefabricated type high-rise residential barrel shuttering dense-rib prestressed floor structure system

Abstract

The invention relates to a prefabricated type high-rise residential barrel shuttering dense-rib prestressed floor structure system. The prefabricated type high-rise residential barrel shuttering dense-rib prestressed floor structure system is characterized by involving a vertical barrel structure, horizontal floor structures and construction connection nodes, wherein the construction connection nodes comprise a structural connection point and a building construction node, the vertical barrel structure is connected with the horizontal floor structures through the construction connection nodes together to form a high-rise residential building overall structure. The prefabricated type high-rise residential barrel shuttering dense-rib prestressed floor structure system has the beneficial effects that a barrel shuttering dense-rib prestressed floor structure system is adopted, the variety richness of prefabricated components can be improved, the industrial chain of prefabricated component products is prolonged, and the production efficiency of the prefabricated high-rise residential industry is improved; and the number of a reinforced concrete shear wall can be reduced, and conditions are created for various requirements of a functional room in an unit, so that a user can flexibly arrange and use the room according to the requirements of the user on the premise that the structural components are not damaged or changed by the user.

Description

technical field [0001] The invention belongs to buildings, and in particular relates to a prefabricated high-rise residential cylinder formwork shell dense rib floor structure system. Background technique [0002] At present, the structural system of prefabricated high-rise residential buildings is mostly assembled integral shear wall structure. High-rise residential buildings adopt shear wall structures, low-rise and multi-storey public buildings adopt frame structures, and office buildings, hotels, and residences with high building heights adopt frame and shear wall structures. Prefabricated components generally appear in the form of a single piece, including prefabricated exterior wall panels, prefabricated interior wall panels, laminated beams, laminated floors, prefabricated stairs, prefabricated air-conditioning panels, etc. The joint connection methods are mainly sleeve grouting connection and grout anchor lap connection. Disadvantages: The assembly rate is low, and...

Problems solved by technology

Disadvantages: The assembly rate is low, and there are contradictions in the production capacity and output of prefabricated component factories. Simply relying on the application of a single prefabricated component to increase the assembly rate greatly limits the development of prefabricated buildings. Not only the cost remains high, but also the industrialization of construction cannot be realized. construction efficiency and convenience; in addition, the number and types of components required limit the production efficiency of prefabricated component factories, resulting in contradictions in the production capacity and output of prefabricated component factories; the technical system integration is low, and it is difficult to improve design and construction efficiency

At present, the technical system of prefabricated high-rise residential buildings in my country is equivalent to the traditional cast-in-place construction mode in terms of design and construction. The architectural design, structural design and construction are out of touch, and it is impossible to take the structure into consideration when the initial architectural design is carried out. The top-level planning leads to low technical system integration, making it difficult to improve design and construction efficiency

In particular, it cannot meet people's demand for variable space inside the living unit

Once the high-rise residences built with the current structural system are delivered for use, the form of the use space will be fixed, and it is difficult to renovate, and it is difficult to flexibly adapt to the needs of residents for residential functions in different periods during the entire building life cycle. Contradictions between the ever-changing demand for space use and the fixed form of residential space
