Embodiment Construction

[0031] Please refer to figure 1 and figure 2 As shown, it shows the specific structure of the first embodiment of the present invention, including the concrete column 10, the beamless floor 20 and the cross double angle steel 30 and the reinforcement 40 in the beamless floor 20, the concrete column 10 Integral pouring with beamless floor 20.

[0032] Among them, such as image 3 As shown, the cross double angle steel 30 is located at the connection node where the concrete column 10 intersects with the beamless floor 20 . The cross double angle steel 30 is housed in the plane of the beamless floor 20, and it includes a first crossbeam 31 and a second crossbeam 32, wherein the length of the first crossbeam 31 is about twice that of the second crossbeam 32, and the second crossbeam 32 has Two sections, the two second beams 32 are vertically welded on both sides of the center of the first beam 31 respectively, and the connection strength is ensured through welding calculations...

Abstract

The invention discloses a crossed double angle reinforced flat slab structure, comprising flat slab and concrete columns which are cast into a whole, wherein cross double angles are arranged at joint nodes of the flat slab and the concrete columns, wherein each crossed double angle comprises a first cross beam and a second cross beam which are connected perpendicularly, and both the first cross beam and the second cross beam are of an inverted T-shaped structure consisting of two steel angle leg backs which are welded closely or with a gap reserved; therefore, areas of the joint nodes of the flat slab and the concrete columns are reinforced by cross double angles, the punching resistance of the structure can be effectively improved without additional arrangement of column caps, the effect of improving bending resistance and earthquake resistance of connection between the slab and supporting columns is achieved, the joint nodes of the flat slab and the concrete columns can be processed conveniently, and the construction difficulty can be lowered.

Description

technical field [0001] The invention relates to the technology in the field of civil engineering, in particular to a cross double-angle steel reinforced beamless floor structure. Background technique [0002] Beamless floors are mainly used in building structures, industrial cold storage, oil refineries and other workshops or working platforms that have high requirements for clearance between building floors and limited floor heights. Due to special requirements such as pipeline layout or technology, these places cannot The structure with beam members is characterized in that the reinforced concrete floor slab is directly connected to the vertical support members (such as reinforced concrete columns or shear walls, etc.), and there is no beam member under the floor, and the floor slab itself bears the bending moment completely. and shear force. Due to the limited thickness of the floor slab, the bending moment resistance and punching resistance of the connection position ar...
