Problems solved by technology

However, the column support structure often greatly increases the difficulty of construction, and it will cause the position of the column support to be difficult to handle in the later decoration, affecting the appearance and even affecting the process or pipeline layout
[0004] In addition, on August 27, 2009, China Construction Eighth Engineering Bureau Co., Ltd. applied to the State Intellectual Property Office for the Chinese invention patent floor well-shaped steel shear key (application number 200920308967.0), which requires at least four centers The plug-in (that is, angle steel) is inserted into the four corners of the center of the well-shaped shape, and is further fixed with a ring plate to connect the concrete column and the beamless floor, which will have the disadvantages of complex structure and difficult processing

Embodiment Construction

[0038] Please refer to figure 1 and figure 2 As shown, it shows the specific structure of the preferred embodiment of the present invention, including the concrete column 10, the beamless floor 20 and the well type frame beam 30 in the beamless floor 20, the reinforcement 40, the concrete column 10 and the beamless floor 20 integral pouring.

[0039] Among them, such as figure 2 As shown, the well-type frame beam 30 is located at the connection node where the concrete column 10 and the beamless floor 20 intersect, and is stored in the plane of the beamless floor 20 . like image 3 As shown, the well frame beam 30 includes two transverse stud reinforcement strips 31 and two longitudinal stud reinforcement strips 32, the transverse stud reinforcement strips 31 and the longitudinal stud reinforcement strips 32 are vertically connected to each other, and as Figure 4 As shown, each transverse stud reinforcing bar 31 and longitudinal stud reinforcing bar 32 all include a rect...

Abstract

The invention discloses a well-type framed girder reinforced flat slab connecting structure which comprises a flat slab and a concrete column which are poured integrally, wherein the connecting node part of the flat slab and the concrete column is provided with a well-type framed girder; the well-type framed girder comprises two horizontal bolt nail reinforced bars and two longitudinal bolt nail reinforced bars which are mutually connected vertically, and each horizontal bolt nail reinforced bar and each longitudinal bolt nail reinforced bar respectively comprise a rectangular cross girder and a plurality of bolt nails; and the bolt nails are all vertically welded on the upper surface of the rectangular cross beam. After the flat slab and the concrete column are poured integrally, the well-type framed girder is hidden in the flat slab, and has the advantages of high connecting rigidity and good punching resistant capability, and is convenient for template supporting in node treatment and construction.

Description

technical field [0001] The invention relates to the technology in the field of civil engineering, in particular to a well-type frame beam reinforced beamless floor connection 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 posi...
