Chinese patent application 201320276190.0 discloses a kind of rectangular steel-tube concrete column and girder steel structures with semi-rigid joints structure, on its position by the i iron at rectangular steel pipe coagulation post, T-steel connector is set respectively up and down, by through ribbed high-strength bolt, be fixed on rectangular steel pipe coagulation post, the termination of i iron girder steel is placed between two T-steel connectors, by high strength frictional property bolt, the upper bottom flange of i iron girder steel and upper and lower two T-steel connectors is fixed together.
Chinese patent application 201320642803.8 discloses the through ribbed node of a kind of U-steel connecting-type rectangular steel pipe coagulation post and girder steel, it is by U-steel being adopted fillet weld mode be directly welded on rectangular steel pipe coagulation post jamb, at the web corresponding position of U-steel reserving hole channel; The upper bottom flange of girder steel is connected by high strength friction-type bolt with the upper bottom flange of U-steel or welding manner connects; By through ribbed high-strength bolt, rectangular steel-tube concrete column and U-steel are linked into an integrated entity.
But above-mentioned various node is due to being connected to be completely and being rigidly connected between its concrete frame and steel framed structure, the node of this form of structure, inevitably all more or less cannot guarantee that it has enough vibrations buffer capacities, i.e. shock resistance when meeting stronger grade earthquake generation.
Just because of the existence of above-mentioned reason is in prior art, general all according to the designing requirement of antidetonation grade, the combination properties such as the intensity of employing enhancing each structural member itself, rigidity, to realize the raising of whole shock resistance.Yet, thisly mainly by strengthening the means of defense technique in advance of the combination properties such as intensity, rigidity of each structural member itself, often there is larger limitation, be mainly, on the one hand, owing to cannot predicting exactly the earthquake intensity that may meet with future, thereby, in practical operation, often there is the significantly rising of the material cost of amount of redundancy due to excessive; On the other hand, thisly mainly by strengthening the means of defense technique in advance of the combination properties such as intensity, rigidity of each structural member itself, be often difficult to seeking a suitable equalization point between rational deadweight and intensity, rigidity.And above-mentioned node structure, also cannot avoid in extreme climate situation, the local damage that exists bigger difference institute reason to expand with heat and contract with cold in the node structure causing due to coefficient of thermal expansion between concrete and steel, and then affect application life of whole node structure.
Utility model content
The purpose of this utility model is, a kind of simple in structure, easy construction is provided, and has the rectangular steel-tube concrete column with extended end plate and the girder steel through ribbed node of better shock resistance and the anti-ability of expanding with heat and contract with cold.
The utility model for achieving the above object technical issues that need to address is, in the rigidly connected while, how to give node structure certain flexibility, i.e. shock-absorbing capacity, to improve the shock resistance of node structure and the technical problem of the anti-ability of expanding with heat and contract with cold.
The utility model is to solve the problems of the technologies described above adopted technical scheme to be, a kind of rectangular steel-tube concrete column with extended end plate and girder steel through ribbed node, comprise rectangular steel-tube concrete column, i iron girder steel; It is characterized in that, also include Force transmission parts;
Described Force transmission parts comprises extended end plate, through ribbed high-strength bolt and angle steel;
The upper and lower alar part of described i iron girder steel respectively with described extended end plate by being welded to connect, the belly of described i iron girder steel is connected by high strength friction-type bolt with described angle steel;
Described extended end plate is connected by described through ribbed high-strength bolt with described rectangular steel-tube concrete column, and the tail end of described through ribbed high-strength bolt adopts respectively double nut fastening;
Between described extended end plate and described rectangular steel-tube concrete column, be also provided with rubber mat plate.
The technique effect that technique scheme is directly brought is, because the modulus of elasticity between rubber and the extended end plate of steel plate material differs greatly, both are used in conjunction with, when bearing pressurized, rubber tile and steel plate be radially distortion all, but the deformation ratio rubber tile of steel plate is little, it is the constraint that rubber tile is subject to steel plate, the core of bearing is approximately the state of three axle pressurizeds, so bearing has higher axial carrying capacity, and compressive strain is also very little;
And when bearing is subject to shearing action, steel plate can not retrain the shear strain of rubber tile, the horizontal distortion of bearing is approximately the stack of each sheet rubber horizontal distortion, so the horizontal distortion of bearing is very large.
