Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the embodiments and accompanying drawings, but the present invention is not limited thereto.

[0025] Such as Figure 1-3 The shown steel-concrete composite slab-column structure includes a reinforced concrete slab 101 and a reinforced concrete column 102 , wherein a steel support 103 for supporting the reinforced concrete slab 101 is provided at the top of the reinforced concrete column 102 .

[0026] The steel frame support 103 is composed of a closed hoop 104 enclosing the top of the column and a joist 105 connected with the closed hoop 104 and extending outward along the bottom surface of the reinforced concrete slab 101 . The closed hoop 104 is welded by rectangular steel pipes, and the overhanging joists 105 are arranged along the periphery of the hoop, and the number, section and length thereof can be determined according to design requirements. The steel frame support 103 encloses the c...

Abstract

The invention discloses a steel-concrete composite plate-column structure comprising reinforced concrete plates and reinforced concrete columns. Steel frame brackets are defined at the column tops ofthe reinforced concrete columns and comprise trimming beams; the steel frame brackets are provided with sleeve hoops defining the column tops, and the trimming beams connected with the sleeve hoops and extending outwards along the bottom layers of the reinforced concrete plates; and the trimming beams are connected with fasteners embedded in the reinforced concrete plates. Compared with a traditional reinforced concrete flat plate structure with a column cap, the steel-concrete composite plate-column structure effectively utilize the high strength property of steel, the problem that a roller shutter door cannot be mounted to the top due to blocking of the traditional column cap is solved, a receding groove is reserved between the trimming beams, thus a space is provided for mounting of theroller shutter door, and the roller shutter door can be mounted to the top.

Description

technical field [0001] The invention belongs to the field of building structures, and in particular relates to a steel-concrete composite slab-column structure. Background technique [0002] Reinforced concrete slab-column structure, commonly known as beamless floor structure, refers to a structural system in which the structural skeleton is connected by reinforced concrete slabs and reinforced concrete columns through slab-column joints. The slabs can be designed as concrete slabs, ribbed concrete slabs, The hollow sandwich concrete slab and the two-way densely ribbed concrete slab can be designed as ordinary reinforced concrete slabs, partially prestressed concrete slabs, and steel fiber reinforced concrete slabs according to different reinforcements; the columns are generally reinforced concrete rectangular columns or columns. [0003] The column cap is set on the column top of the concrete slab-column structure to increase the support area of ​​the column to the slab. Wh...
