Description
Technical field
The utility model belongs to structural steel design and construction field, relates to a kind of steel structure node form for antidetonation, particularly a kind of square steel pipe-H profile steel joint structure.
Background technology
In recent years, China's steel building fast development, < < construction industry development " 12 " the planning > > that firmly portion of building prints and distributes is clear and definite, during " 12 ", the shared ratio of structural steelwork will be increased, advance Construction of Resource-preserving Society, using super high steel structure engineering and residential project key technology as basic research problem, for carrying out Steel Housing Industrialization subject study, provide foundation, promote steel house.Steel house is in the existing comparatively ripe experience of developed country, and in China, application also has more than 20 year, but fails extensively to promote always, and key node design level backwardness is one of the main reasons.
In existing node structure, as shown in Figure 1, Figure 2 and Figure 3, square steel pipe-H shaped steel outer annular-stiffer joint form is existing comparatively ripe application in encased structures, it is extensive that application in steel building is also tending towards, on its column of making at square steel pipe 1, be fixedly installed two reinforcing rings 4, strengthening web 3 is set between reinforcing ring 4, and strengthening web 3 is welded and fixed with two reinforcing rings 4 and column 1 respectively, and H shaped steel fine strain of millet 2 is welded into one with reinforcing ring 4 and 3 pairs of strengthening webs again.Result of study shows, because quadrate steel pipe column rigidity on both direction is consistent, can avoid the drawback of H shaped steel cross section insufficient rigidity on weak direction of principal axis, strengthen ring type bean column node good mechanical properties, node area bearing capacity is greater than beam body, meet the requirement of " strong column and weak beam; node is stronger ", ring flat-plate and steel pipe column co-operation, can pass to post limb by beam internal force reliably, and tube wall is stressed evenly, has prevented stress raisers.But engineering practice also shows, there is following shortcoming in square steel pipe-H shaped steel outer annular-stiffer node:
(1) in order to meet the requirement of plastic hinge, the strength and stiffness of reinforcing ring 4 will be strengthened, otherwise be just prone to the situation of reinforcing ring 4 criplings; (2) between reinforcing ring, to weld the shearing that strengthening web 3 carrys out transfer beams web, reinforcing ring will weld by full penetration butt weld and flange of beam, web also will be connected by full penetration butt weld with the web between reinforcing ring, weld seam is many, welding job amount is large, and welding quality is had relatively high expectations; (3) in order to meet welding and the remaining release of welding, often will cut up and down fillet 5 by the strengthening web between web and reinforcing ring, manufacturing procedure is more.
In sum, market is simpler in the urgent need to a kind of structure, construct easier, and the new steel structure joint form that reliability is higher.
Summary of the invention
The purpose of this utility model is to address the above problem, and the outer annular-stiffer formula beam-column node structure that a kind of easy construction, strength and stiffness are higher, can meet better antidetonation demand is provided.
The utility model outer annular-stiffer formula beam-column node structure is to realize like this, comprise the crossbeam that column that steel pipe is made and H shaped steel are made, the external surface of column is fixedly installed reinforcing ring, described reinforcing ring comprises upper and lower reinforcing ring plate, it is characterized in that crossbeam insertion is arranged between upper and lower reinforcing ring plate, in crossbeam the upper and lower edge of a wing of H shaped steel respectively with upper and lower reinforcing ring plate corresponding matching, together with crossbeam and column and upper and lower reinforcing ring plate are welded and fixed respectively.Wherein, can also fill concrete in the steel pipe tube chamber of formation column.
In crossbeam, the matching part of the corresponding column in the upper and lower edge of a wing of H shaped steel all arranges gap, and only the web of H shaped steel and column are weldingly connected, and the upper and lower edge of a wing of H shaped steel is weldingly connected with upper and lower reinforcing ring plate respectively.In crossbeam, the upper and lower edge of a wing of H shaped steel is connected by fillet weld with upper and lower reinforcing ring plate respectively, between the web of H shaped steel and column, also adopts fillet weld to be connected.For the ease of fillet weld is set, the width of the upper and lower edge of a wing matching part of upper and lower reinforcing ring plate and H shaped steel is greater than respectively the width on the upper and lower edge of a wing.As a same reason, the spacing between upper and lower reinforcing ring plate is identical with horizontal depth of beam, is convenient between the corresponding upper and lower reinforcing ring plate in the upper and lower edge of a wing of H shaped steel, fillet weld is set in crossbeam.
It is to be noted, the cross-sectional profiles that forms the steel pipe of column in the utility model is shaped as circle or polygon, and described polygon comprises even ten polygons more than limit of triangle, quadrangle, pentagon, hexagon, heptagon, octagon, nonagon, decagon.
Compared with prior art, the utility model outer annular-stiffer formula beam-column node structure tool has the following advantages:
1) utilize crossbeam directly coordinate with column and upper and lower reinforcing ring plate and adopt the form of fillet weld to be welded and fixed, omitted processing and the assembly process of existing strengthening web, relate to workpiece few, structure is simpler, also still less, welding job amount is little for weld seam, constructs more convenient;
2) the H type steel support that forms crossbeam, between upper and lower reinforcing ring plate, is welded and fixed rear globality better, and reinforcing ring region Rigidity and strength significantly improves, and is difficult for flexing phenomenon occurs, more safe and reliable in use procedure;
3) use in the situation of same size material, the strength and stiffness of the utility model outer annular-stiffer formula beam-column node structure are better, more easily realize the object that moulding hinge is moved outward, improve the ductility of structure, are conducive to save material, reduce costs.
The simple structure of the utility model outer annular-stiffer formula beam-column node structure, good integrity, can effectively avoid the situation of reinforcing ring plate cripling to occur, dependable performance, it constructs convenient, and construction cost is low, can be widely used in the steel pipe post of various steel buildings and being connected of H section steel beam.
