Abstract

The utility model relates to a one-way restraint performance based connecting joint of a steel structure. The one-way restraint performance based connecting joint of the steel structure is composed of a connecting steel plate, a reinforcing steel plate and a shear connectors, wherein the reinforcing steel plate and the connecting steel plate are connected in a three-section mode, and the three-section mode is that the upper sections of the reinforcing steel plate and the connecting steel plate are closely attached, semicircle holes are formed in the middle sections of the reinforcing steel plate and the connecting steel plate, and the lower sections of the reinforcing steel plate and the connecting steel plate are welded together. The shear connectors are welded on the two sides of the connecting steel plate, and are closely attached to the upper end of the reinforcing steel plate. Welding lines between the shear connectors and the connecting steel plate meet the fact that the welding lines are in good condition in a low-level earthquake and cracks in a high-level earthquake. The one-way restraint performance based connecting joint of the steel structure can bear a large axial force, elastic connection can be achieved in the connecting steel plate plane, and the one-way restraint performance based connecting joint of the steel structure can bear a large bending moment. In the low-level earthquake, the elastic connection can be achieved outside the connecting steel plate plane to ensure that the connecting joint is in an elastic stage; in the high-level earthquake, performance based connection can be achieved outside the connecting steel plate plane, and the connecting joint enters a plastic stage, and more earthquake energy is consumed, and structure safety is guaranteed. The one-way restraint performance based connecting joint of the steel structure is simple in structure and convenient to manufacture, and saves materials.

Description

Steel work unilateral constrain performance-based connected node
Technical field
The utility model belongs to construction steel structure node technology field, relates in particular to a kind of steel work unilateral constrain performance-based connected node.
Background technology
The basic antidetonation basic intensity of the building target that China's " seismic design provision in building code " (GB50011-2010) stipulates is: when the frequently occurred earthquake that is lower than this area seismic fortification intensity affects, generally be not damaged or need do not repair and to continue to use, when being equivalent to the earthquake effect of this area seismic fortification intensity, may be damaged, but still can continue to use through running repair; When being higher than rarely occurred earthquake that this area seismic fortification intensity estimates and affecting, unlikelyly collapse or life-threatening heavy damage occurs.This just requires building structural element and node than the low water-mark earthquake time, remains on elastic stage; And when suffering the high levels earthquake, enter the plastic stage, certain deformation and failure occurs.When building suffers the high levels earthquake effect, can make the part secondary nodes produce larger plastic strain earthquake energy, thereby avoid main member and node generation heavy damage, so that malformation and destructiveness are controlled in the permissible range, guarantee integrally-built safety.Therefore, for the part secondary nodes of structure, can take specific form and necessary structure, make it under than the low water-mark earthquake, keep elasticity, suffer to enter the plastic stage under the high levels earthquake, can produce larger rotational deformation at specific direction.And, when structure is assessed and repaired after shake, might only need reparation shear connector or a small amount of weld seam can recover structural performance.At present, in the construction steel structure field, there is no the node of above-mentioned form.
Summary of the invention
The deficiency that can not in time enter the plastic stage in order to improve existing steel structure node under the high levels earthquake, the purpose of this utility model is to provide a kind of simply constructed steel work unilateral constrain performance-based connected node.
For achieving the above object, the technical solution adopted in the utility model is: a kind of steel work unilateral constrain performance-based connected node, formed by junction steel plate 1, put more energy into steel plate 2 and shear connector 3, wherein: the steel plate 2 of putting more energy into is divided into upper, middle and lower segment, epimere and the junction steel plate 1 of the described steel plate 2 of putting more energy into fit tightly, described stage casing of putting more energy into steel plate 2 has semicircle orifice, the hypomere of the described steel plate 2 of putting more energy into and junction steel plate 1 welding; Shear connector 3 is welded in junction steel plate 1 both sides, and fits tightly in steel plate 2 upper ends of putting more energy into; During use, junction steel plate 1 two ends respectively with two steel Member Weldings.
In the utility model, described shear connector 3 satisfies with the weld seam of junction steel plate 1: intact under than the low water-mark earthquake, rupture under the high levels earthquake suffering.
The beneficial effects of the utility model are: node can be realized the Performance Design target, can bear larger axial force; Can realize in the junction steel plate plane that elasticity connects, and can bear larger moment of flexure; Under than the low water-mark earthquake, can realize outside the junction steel plate plane that elasticity connects, and guarantees that node is in elastic stage; Under the high levels earthquake, can realize outside the junction steel plate plane that performance-based connects, node enters the plastic stage, consumes to shake more energy, guarantees structural safety; Simple structure, easy to make, economical with materials.
Description of drawings
Fig. 1 is front elevation drawing of the present utility model.
Fig. 2 is the I-I sectional view of Fig. 1.
Number in the figure: 1 is junction steel plate, and 2 are the steel plate of putting more energy into, and 3 is shear connector.
The specific embodiment
Further specify by reference to the accompanying drawings the utility model below by embodiment.
Embodiment 1: as depicted in figs. 1 and 2, the utility model is comprised of junction steel plate 1, put more energy into steel plate 2 and shear connector 3.During use, junction steel plate 1 two ends respectively with two steel Member Weldings, the steel plate 2 of putting more energy into adopts epimere to fit tightly with junction steel plate 1, open semicircle hole, stage casing, " syllogic " connected mode of hypomere welding.2 pairs of junction steel plate 1 deformity out of plane of steel plate of putting more energy into have certain effect of contraction, can prevent under the larger load flexing outside junction steel plate 1 plane.Node can realize that in junction steel plate 1 plane elasticity connects.Under than the low water-mark earthquake, shear connector 3 can effectively prevent junction steel plate 1 and the steel plate 2 epimere generation relative slidings of putting more energy into, and can realize that outside junction steel plate 1 plane elasticity connects, and guarantees that node is in elastic stage; Under the high levels earthquake, shear connector 3 is cut off with the weld seam of junction steel plate 1, relative sliding can occur in junction steel plate 1 and steel plate 2 epimeres of putting more energy into, node has certain turning power in junction steel plate 1 plane, can realize that performance-based connects, and entering the plastic stage, the sliding friction of the rotation of node and junction steel plate 1 and steel plate 2 epimeres of putting more energy into can consume more seismic energy.
