Problems solved by technology

[0005] The purpose of the present invention is to provide a partially clad steel-concrete composite component and its processing method. The purpose of this invention is to solve the problem of high cost of corrosion and fire prevention of steel beams through concrete cladding, and improve durability; Concrete beams work together, and at the same time, the steel plates on both sides are far away from the neutral axis of the test piece, and the bending rigidity is relatively large, which can greatly improve the structural strength and rigidity and reduce costs; realize the standardization of component manufacturing through steel plates and studs, and reduce the amount of processing , reduce processing cost

Embodiment 1

[0098] Such as Figure 1-4 As shown, a partially clad steel-concrete composite member provided in this embodiment includes: a first side steel plate 100, a second side steel plate 200, a stud 500, a repair welding steel plate 400, a stiffening steel plate 300, a steel skeleton 600 and Concrete 700.

[0099] The first side steel plate 100 and the second side steel plate 200 are arranged in parallel and spaced; It is fixedly connected with the second side steel plate 200.

[0100] The two stiffened steel plates 300 divide the partly clad steel-concrete composite member into the connection area A1 on the outside of the two stiffened steel plates 300, and the prefabricated area A2 between the two stiffened steel plates 300; the two stiffened steel plates 300 and the first side steel plate 100 and the second side steel plate 200 enclose a prefabricated abdominal cavity in the prefabricated area A2; concrete 700 is poured in the prefabricated abdominal cavity; a steel skeleton 600 i...

Embodiment 2

[0125] The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that:

[0126] Such as Figure 7 As shown, the partially clad steel-concrete composite member 3 is embedded in the wall 4 as a column; the partially clad steel-concrete composite member 3 is coated with an external anti-corrosion layer on the outer surface of the outer steel plate 3a near the outer side of the wall (not shown), a glass wool board 10 is laid on the outer anti-corrosion layer, which is used to block part of the coated steel-concrete composite member as a thermal bridge to transfer heat flow between the indoor and outdoor sides of the wall body 4 . On the projection plane parallel to the wall 4 , the format size of the glass wool board does not cover the entire wall 4 , and the format of the glass wool board only covers all or part of the cladding steel-concrete composite member 3 .

[0127] Different from the thermal insulation board or thermal insulation la...

Embodiment 3

[0142] This embodiment discloses a composite structure building, such as Figure 8 As shown, it includes: beams (not shown), columns 30 , shear walls 40 and floors (not shown).

[0143] Wherein, the column body 30 is composed of a partially clad steel-concrete composite member in Embodiment 1 or 2. A shear wall 40 is arranged between the two columns 30 .

[0144] The shear wall 40 includes a body of wall and a wall connector 43 arranged in the wall; the body of the wall includes an inner plate 41 and an outer plate 42 arranged at intervals along its thickness direction; two ends of the inner plate 41 and the outer plate 42 are provided with The end plate 45 is fixedly connected to the first side steel plate and the second side steel plate on the column body 30 through the end plate 45 . In order to avoid the thermal bridge effect, the end plates can also be omitted, and the inner and outer plates are directly connected to the side steel plates on the column.

Abstract

The invention provides a partially cladding steel-concrete composite member and a composite structure building thereof. The composite member includes a first side steel plate, a second side steel plate, studs, a repair welding steel plate, stiffening steel plates, a reinforcement framework and concrete; the two stiffening steel plates, the first side steel plate and the second side steel plate enclose a prefabricated web cavity in a prefabricated area; concrete is poured into the prefabricated web cavity; and the reinforcement framework is embedded in the concrete. According to the partially cladding steel-concrete composite member and the composite structure building thereof, the advantages of convenient connection and good anti-seismic performance of a steel structure are developed, andmeanwhile the advantages of high rigidity, good anti-corrosion and fire-proof performance and low cost of a concrete structure are integrated; and by using the combined action of steel-concrete, the defects of poor anti-corrosion and fire-proof performance, low rigidity and high cost of a steel member are overcome, and many advantages of the standardized production, assembly construction, long-term durability, economic applicability and the like of the member are achieved, the competitive advantage of the steel structure is greatly enhanced, and the application prospect in prefabricated buildings is broad.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a partially clad steel-concrete composite component and a composite structure building thereof. Background technique [0002] The cast-in-place concrete shear wall residential structure is the mainstream of current residential buildings in my country, but the cast-in-place structure has many shortcomings such as wet work on site, low production efficiency, waste of resources, environmental pollution, and inability to achieve four sections and one environmental protection, making it difficult to adapt to the modernization of the construction industry development needs. Compared with concrete structures, steel structures have the advantages of "light, fast, good, and economical". At the same time, they are green building materials that can be recycled and reused. Compared with other building materials commonly used at present, they are most conducive to energy saving, ma...
