Abstract
The utility model discloses a structure node synchronously meeting constraint requirements on space in different directions. The structure node adopts an I-steel which can meet requirements on axial force and shearing force generated between nodes as basic connecting material; the middle part of the I-steel is provided with a connecting pin which can meet requirements on vertical shearing force and hinge connecting axial force between a curtain wall column and a suspended steel platform and can release X, Z plane bending moment; the upper flange and the lower flange of the I-steel are provided with a horizontal-connecting steel plate which can resist horizontal seismic shearing force in X, Y directions. The advantages of the structure node are as follows: firstly, the simple axial hinged node constraint is changed into compound constraint; secondly, a single-direction axial hinge has better out-of-plane anti-seismic performance and anti-deformation performance; thirdly, good damping is provided and can obviously reduce seismic role and temperature role, so as to protect the system safety of the hanging curtain wall; fourthly, the structure of the connecting node is simple, therefore, even through the structure encounters rare seismic role, the node connecting plate can bend and is easy to repair.
Description
Technical field
The utility model relates to a kind of Engineering Structure Component link technique, particularly a kind of structure node that satisfies space different directions constraint requirements simultaneously.
Background technology
In actual engineering structures, structural entity is made up of many members, and these members couple together in the node mode again, forms one and complete can satisfy the structure that design function requires, and reaches the purpose of use.The connection request of structure of different nature or different structure member varies, so the performance of node often determines the ability of structure and satisfies the degree that design function requires.
An engineering is arranged, and form of structure is irregular many support tubes, encorbelment greatly, large span complex space combination steel work.In engineering reality, the huge truss platform and the outside of encorbelmenting kept and required between glass, metal curtain wall to be connected, and this connection request node energy while TRANSFER METHOD is to wind load, and restricted release cantilever frame of energy and the vertical displacement of curtain wall junction simultaneously.Because there are anti-side rigidity in curtain wall and system, therefore the connected node between curtain wall and cantilever frame can bear the vertical equity shearing, because curtain wall links to each other with roof truss, the roof system curtain wall system produces the normal direction horizontal movement under different action of thermal difference, this connected node requires around outer curtain wall construction plane turning power is arranged.Required joint structure must satisfy above-mentioned space different directions constraint requirements simultaneously.
In actual engineering structures, the connected mode kind of member is a lot, and rigid joint, elastic panel nodes, limited rigid joint, sliding node, power consumption damping node etc. are arranged.But node that this engineering is required and the maximum difference of above even node are that the major axes orientation constraint of three spaces of node is widely different, or principle difference is arranged.As required node three major axes orientations are arranged, X is to (this paper is called normal direction), and Y is to being side direction or vertical, and Z is vertical.X is delivered on the big main body of structure reactance to the structure blast of naming a person for a particular job, the wind suction that connect; Z can not be delivered on the curtain wall post of the node outside too much to the vertical deformation that will satisfy the cantilevered structure main body; Y is to transmitting side direction thermal stresses and geological process horizontal loading; Y, Z discharge roof truss and produce structure temperature and geological process distortion to turning power will be arranged.Through looking into, the constructing technology that the needed connected node of this engineering exists at present all can't satisfy.
The utility model content
In order to solve the technical problem that the joint structure that exists in the prior art can't satisfy the required structure node that can satisfy space different directions constraint requirements simultaneously of this engineering, the utility model provides a kind of structure node that satisfies space different directions constraint requirements simultaneously.
The utility model for the technical scheme that solves the problems of the technologies described above employing is: a kind of structure node that can satisfy space different directions constraint requirements simultaneously is provided, the described structure node that satisfies space different directions constraint requirements simultaneously, select for use the i iron that satisfies the axle power that produces between node and shearing needs as being connected material substantially, adopt at i iron connector middle part can satisfy the curtain wall post with encorbelment between the steel platform vertical shear be hinged a power needs and can discharge X, the connecting pin select of Z plane bending moment, the bottom flange is established and can be resisted X on i iron, Y connects steel plate to the level of horizontal earthquake action shearing.Thereby described steel plate is can produce as X, when the Z face rotates to stretch or compress to increase rotary resistance to make connected node rotate the steel sheet of restriction to some extent.Described X is to being normal direction, and Y is to being side direction or vertically, and Z is to being vertical.
Advantage of the present utility model: the one, with simple axle hinged joint constraint becoming compound constant; The 2nd, make one-way shaft hinge have preferably antidetonation, non-deformability outside the plane; The 3rd, have damping preferably, simple hinge does not possess damping function, but after adding the arc of horizon plate, turning power is retrained to some extent, has damping preferably, can more obviously alleviate earthquake and temperature action, and curtain wall system safety is hung in protection; The 4th, the connected node simple structure, even structure meets with rare geological process, the node junction plate can be surrendered, and easily repairs.

The specific embodiment
A kind of structure node that satisfies space different directions constraint requirements simultaneously that present embodiment provides, as Fig. 1, the described structure node that satisfies space different directions constraint requirements simultaneously, select for use the i iron that satisfies the axle power that produces between node and shearing needs as being connected material substantially, adopt at i iron connector middle part can satisfy the curtain wall post with encorbelment between the steel platform vertical shear and be hinged a power needs and can discharge the connecting pin select of X, Z plane bending moment, the bottom flange is established and can be resisted X, the Y level connection steel plate to the horizontal earthquake action shearing on i iron.Thereby described steel plate is can produce as X, when the Z face rotates to stretch or compress to increase rotary resistance to make connected node rotate the steel sheet of restriction to some extent.Described X is to being normal direction, and Y is to being side direction or vertically, and Z is to being vertical.
The utility model connected node structure application process is as follows:
1. determine the angle range of connected node, determine the i iron joint gap according to angle range.
