Description

Technical Field

[0001] The utility model relates to a column-drawing type building structure, belonging to the technical field of civil construction. Background Art

[0002] Due to functional needs, some buildings must arrange large spaces in some areas of the middle floors of the house. No structural components shall be set up in the large space. The layer where the large space is located must consider removing columns, that is, frame columns shall not be set in this space. The horizontal structural system of the upper floors after the columns are removed often belongs to a large-span system. When the span exceeds 20m, the design becomes difficult. Traditional large-span horizontal structural designs often use steel-reinforced concrete beams, prestressed concrete beams or steel truss empty layers. Among them, steel-reinforced concrete beam refers to the arrangement of steel sections inside the reinforced concrete section. Although the cross-section of the concrete beam is reduced to a certain extent, the cross-section is still large, and formwork is required before construction and production. A full-height scaffolding must be set up under the formwork, and the construction cost is relatively high; prestressed concrete beam refers to the application of prestress inside the concrete beam. On the one hand, the construction process of prestressing has high construction requirements, and on the other hand, prestressed concrete beams need to be supported by formwork before construction and production. A full-height scaffolding must be set up under the formwork, and the construction cost is relatively high; steel truss empty layer refers to the installation of steel trusses. The range between the upper chord and the lower chord of the steel truss is not used as building space, which will cause waste of building space. The installed steel trusses raise the total height of the building and affect the overall cost of the building.

[0003] As can be seen from the above, the existing column-drawn building structure has a high cost for the design of large-span horizontal structural components and insufficient building space utilization, which affects the economy and practicality of the device. Utility Model Content
