Abstract
The utility model relates to civil engineering structures, in particular to a steel tube concrete column-plate hinging node, which includes a steel tube concrete column and a concrete floor. The steel tube concrete column and the concrete floor are connected through a pivoting support and have special-shaped structures, and clearances are arranged at all corners of the special-shaped pivoting support. Compared with the prior art, the utility model adopting the technical scheme has the advantages as follows: the change of the concrete column section form results in no protruding phenomenon at the joint of the concrete column and the inner and the outer walls, so that the indoor space can be utilized more efficiently; and when the structure has side sway, the deformation of pivoting support can be dissipated depending on the clearances and under the action of gravitational load and local flexural moment, and the local flexural moment of the node keeps at a lower level.
Description
Technical field:
The utility model relates to civil engineering structure, a kind of specifically steel tube concrete column-plate hinged joint node.
Background technology:
Slab-column connections under the conventional design, its design of node all are to be designed to the master with rigid joint; Under the load acting in conjunction in the horizontal and vertical direction of such node, moment of flexure and the shearing of the transmission disequilibrium moment of flexure to cause, therefore its punching bearing capacity is subjected to influence to a certain degree.The basic reason of slab-column connections poor seismic behavior is that it has been stress concentration point in the structure that node is under the vertical uniform load q, stressed very complicated, because the effect of unbalanced moment at first plastic strain occurs near the plate node, the development of plastic strain reduces the anti-impact of the plate ability of cutting and punching failure takes place during earthquake.The fundamental way that improves the slab-column connections anti-seismic performance is to make the stressed simplification of node, avoids node unbalanced moment to occur.
Order has the most common slab column system, generally adopts circle or rectangular column, and its weak point is outside corner's protruding wall that the inside and outside wall column in room connects, and has not only hindered the indoor layout in attractive in appearance but also unfavorable room, influences effective utilization of room space.
Summary of the invention:
It is the steel tube concrete column-plate hinged joint node that helps indoor layout attractive in appearance that the purpose of this utility model is to overcome the deficiency of background technology and provide a kind of.
The utility model adopts following technical scheme:
A kind of steel tube concrete column-plate hinged joint node, comprise steel core concrete column, concrete floor, be connected by pivoting support between described steel core concrete column and the concrete floor, described steel core concrete column and pivoting support all are polymorphic structure, and the every nook and cranny of this abnormity pivoting support is equipped with the slit.
The utility model of employing technique scheme compared with prior art, this node is only born vertical load, do not bear or seldom bear horizontal loading, and make it under big shake, have bigger anti-sidesway ability, it utilizes the change of concrete column section form to make concrete column and interior exterior wall junction not have the protrusion phenomenon, makes the room interior space more effectively to utilize; When structure generation sidesway, pivoting support relies on the dissipate distortion of its generation of slit under the effect of gravitational load and local moment of flexure, the local moment of flexure of node is remained on the less level.

The specific embodiment:
Embodiment 1:
A kind of steel tube concrete column-plate hinged joint node referring to accompanying drawing 1,2, is made up of cross-shaped steel pipe concrete column 1, cross pivoting support 2, concrete floor 3, slit 4, the vertical muscle 5 of floor.Cross-shaped steel pipe concrete column 1 is welded by steel plate, and be connected with cross pivoting support 2, concrete floor 3 directly is supported on the cross pivoting support 2, and be cast in it, cross pivoting support 2 each bight are equipped with the slit 4 of 3 millimeter together, in the vertical muscle 5 intersections punching of cross-shaped steel pipe concrete column 1 and floor, the vertical muscle 5 of the floor in the concrete floor 3 passes cross-shaped steel pipe concrete column 1, guarantees that with this floor can not weaken at the anti-bending bearing capacity at node place; Cross pivoting support 2 directly relies on the distortion of slit 4 its generations of dissipation in the effect of gravitational load and local moment of flexure when structure generation sidesway, the local moment of flexure of node is remained on the less level, and its local moment of flexure is by the vertical stress difference balance of cross pivoting support 2.
Embodiment 2:
A kind of steel tube concrete column-plate hinged joint node referring to accompanying drawing 3,4, is made up of L shape steel tube concrete column 1, L type pivoting support 2, concrete floor 3, slit 4, the vertical muscle 5 of floor.L shape steel tube concrete column 1 is welded by steel plate, and be connected with L type pivoting support 2, concrete floor 3 directly is supported on the L type pivoting support 2, and be cast in it, L type pivoting support 2 each bight are equipped with the slit 4 of 3 millimeter together, in the vertical muscle 5 intersections punching of L shape steel tube concrete column 1 and floor, the vertical muscle 5 of the floor in the concrete floor 3 passes L shape steel tube concrete column 1, guarantees that with this floor can not weaken at the anti-bending bearing capacity at node place; L type pivoting support 2 directly relies on the dissipate distortion of its generations of slit 4 in the effect of gravitational load and local moment of flexure when structure generation sidesway, and the local moment of flexure of node is remained on the less level, and its local moment of flexure is by the vertical stress difference balance of L type pivoting support 2.
Embodiment 3:
A kind of steel tube concrete column-plate hinged joint node referring to accompanying drawing 5,6, is made up of square shaped pipe concrete column 1, square type pivoting support 2, concrete floor 3, slit 4, the vertical muscle 5 of floor.Square shaped pipe concrete column 1 is welded by steel plate, and be connected with square type pivoting support 2, concrete floor 3 directly is supported on the square type pivoting support 2, and be cast in it, square type pivoting support 2 each bight are equipped with the slit 4 of 3 millimeter together, in the vertical muscle 5 intersections punching of square shaped pipe concrete column 1 and floor, the vertical muscle 5 of the floor in the concrete floor 3 passes square shaped pipe concrete column 1, guarantees that with this floor can not weaken at the anti-bending bearing capacity at node place; Square type pivoting support 2 directly relies on the dissipate distortion of its generations of slit 4 in the effect of gravitational load and local moment of flexure when structure generation sidesway, and the local moment of flexure of node is remained on the less level, and its local moment of flexure is by the vertical stress difference balance of square type pivoting support 2.
