Embodiment Construction

[0032] Please refer to Figure 1 to Figure 4 As shown, it shows the specific structure of the first embodiment of the present invention, including a concrete column 10, a beamless floor 20, and embedded steel 30 and reinforcement 40 accommodated in the beamless floor 20. The concrete The column 10 and the beamless floor 20 are poured integrally.

[0033] Among them, such as figure 2 As shown, the embedded section steel 30 is located at the connection node where the concrete column 10 intersects with the beamless floor 20 . The embedded section steel 30 is stored in the plane of the beamless floor 20, such as image 3 As shown, it includes a first beam 31 and a second beam 32, wherein the first beam 31 and the second beam 32 are vertically welded, and the connection strength is ensured through the welding calculation of the equal strength design, so that the beam of the floor can be formed Cruciform structure.

[0034] Such as Figure 4 As shown, the first crossbeam 31 is...

Abstract

The invention discloses a built-in steel-type reinforcing no-beam floor system structure, which comprises a no-beam floor system and a concrete post, which are poured as a whole, wherein built-in profile steel is arranged in the position of the connection joint of the no-beam floor system and the concrete post, and comprises a first transverse beam and a second transverse beam; the first transverse beam and the second transverse beam are vertically welded to form a cross-shaped structure; and in addition, the first transverse beam and the second transverse beam are wide-flange H profile steel. According to the invention, the crossed joint area of the concrete post and the no-beam floor system is reinforced by the cross-shaped built-in profile steel, so that the anti-punching performance can be effectively improved, and no post cap is required to be additionally arranged. The built-in steel-type reinforcing no-beam floor system structure can improve the transverse and longitudinal bent resistance and seismic performance of the connection part of the floor system and the support post, provide convenience for processing the joint of the concrete post and the floor system and lower the construction difficulty.

Description

technical field [0001] The invention relates to the technology in the field of civil engineering, in particular to an embedded steel-type 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 are po...
