Building system

Technical Field

The utility model relates to a building system, especially a building system who contains girder steel joint design.

Background

Common construction methods include RC (reinforced concrete) structures, SC (steel reinforced beam column outer surface concrete cladding for fire protection) structures, SRC (steel reinforced concrete) structures, and the like. RC (reinforced concrete) structures can be divided into traditional field casting methods for casting concrete on site and precasting methods which have the advantages of excellent structure quality, safe and rapid construction, economic and reasonable construction cost and the like in recent years. The precasting method is to make a steel bar structure and pour concrete by a standardized operation flow and a modularized mould around a precasting factory or a construction site, and rapidly mass-produce precise precasting components such as columns, beams, plates and the like. Precast members produced in a precast plant or around a construction site are assembled on the construction site by precise handling management and assembling work. Therefore, the workload in a construction site can be reduced to the minimum, the manpower and the construction time are reduced, the construction period is effectively shortened, and the construction quality is ensured. In addition, the precasting construction method can reduce or avoid the construction on the outer wall scaffold, thereby greatly improving the construction safety. The SC structure main body takes 'steel rib beam column' as a main part, and the beam column is coated with concrete for fireproof coating, so that the structure composition is softer and has stronger toughness. The SRC (steel reinforced concrete) structure is a structural mode combining reinforced concrete and steel ribs, the middle of a beam column is supported by the steel ribs, the periphery of the beam column is coated by concrete, the concrete also comprises main steel bars and stirrups, and the steel bars and the steel ribs jointly act to enable the building to have high toughness and tensile strength, however, the house construction cost of the SC structure and the SRC structure is high.

A hybrid construction method is also gradually used based on advantages and disadvantages of various construction methods, and among them, a construction method in which precast columns are used in combination with steel beams to optimize respective advantages of a precast structure and a steel structure is most common. In view of the development of such building constructions, it is desirable in the art to provide methods of manufacturing such beam and column structures, and beam and column structures or systems made thereby, that utilize a minimum number of construction steps to maximize yield and provide the best quality.
