The utility model discloses locate to set up a variable cross section steel corbel at the steel -pipe column with concrete beam connected node, the one end welding is on the steel -pipe column, inherent variable cross section steel corbel upper limb listrium of steel -pipe column and bottom wing listrium correspond the interior stiffener of position welding steel pipe, variable cross section steel corbel opposite side upper limb listrium is bent, form the cascaded surface, go up cascaded surface welding second and arrange the gluten, the cascaded surface welds first row of gluten down, muscle at the bottom of welding first row on the bottom wing listrium, be provided with the bracket web in the middle of the variable cross section steel corbel, one side that the bracket web is close to the steel -pipe column is provided with anchor curved hole, second row end muscle passes and the anchor is bent. The structure atress is simple reasonable, and the security is high, economical and practical.
Description
Technical field:
This utility model technology relates to a kind of steel reinforced concrete structure nodal connection device, particularly relates to the connection node device of a kind of beams of concrete and steel core concrete column.
Background technology:
Building trade Shaped Steel xoncrete structure uses more and more extensive at present, especially applies in large public building.But due to the disconnection of specialty, often designer does not refines the making of the node putting in place or designing inapplicable processing factory or in-site installation on steel reinforced concrete structure connection node.Beams of concrete is connected with profile steel concrete column, domestic following several type of attachment and the weak point thereof of common are: use steel bushing to connect, steel bushing is not easy to welding location at steel pipe curved surfaces, arcuate surface welding operation difficulty, and it is too small to be welded to connect area, being difficult to meet structure stress requirement, integrated operation difficulty is big；Use uiform section steel corbel connect, when being double for beam gluten, second row reinforcing bar must perforate on steel pipe column, weaken the cross section of steel pipe column, and steel pipe column perforate be higher in technological requirement, perforate inefficiency, be unfavorable for that factory makes；Nodes domains is amplified, steel pipe column walked around by the reinforcing bar of beams of concrete, bending construction it is not easy to when reinforcing bar is more, it addition, because considering that reinforcing bar, around post, can make beams of concrete under equal conditions, steel pipe column need bigger cross section on She Ji, concrete column cross section is caused to become big, it is unfavorable for that space utilizes, and increases cost, uneconomical.
Summary of the invention:
This utility model solves the technical problem that and is, overcomes the deficiency of background technology, it is provided that a kind of structure stress advantages of simple, and safety is high, economic and practical, particularly convenient for steel construction factory process and the node apparatus of site operation.
Solution of the present utility model is the connection node device of a kind of beams of concrete and steel core concrete column, at steel pipe column with concrete beam connecting node, a variable cross-section steel corbel is set, the thicker one end of Variable Section Steel bracket is welded on steel pipe column, the interior stiffener in Variable Section Steel bracket top flange plate and bottom wing listrium correspondence position welded still pipe of steel pipe column, Variable Section Steel bracket opposite side top flange plate bending, form cascaded surface, upper cascaded surface welding second row gluten, downstairs face welding first row gluten, muscle at the bottom of first row is welded on bottom wing listrium, bracket web it is provided with in the middle of Variable Section Steel bracket, bracket web is provided with the curved hole of anchor near the side of steel pipe column, muscle at the bottom of second row and other reinforcing bar are curved through also anchor.In pipe, stiffener is welded in steel duct, concordant with bracket bending top flange plate and top flange plate, bears and transmit the internal force that beams of concrete is transmitted by bracket；Reinforcing bar and upper and lower flange plate have and bigger are welded to connect area, rather than the single-point of steel bushing connects, being reduced or avoided as far as possible and punch so that weakening cross section on steel pipe column, Variable Section Steel bracket factory is easy to make, still can punch on steel pipe when especially meeting the double arrangement of reinforcement of beams of concrete.This kind of Variable Section Steel bracket connected mode maximum possible can reduce member section, makes full use of space.Ensureing structural safety, on the premise of economical rationality so that processing factory makes simple, job site easy construction.
Section steel bracket is characterised by there be the radian identical with steel pipe column surface with one end of steel pipe column welding, top flange plate is bent into stepped, bottom wing listrium is flat board or stepped, near You Maowan hole, steel pipe column side on bracket web, welding top flange plate, bottom wing listrium and bracket web are on steel pipe column, in I-shaped welding.Increase work stress surface, make node safer.
Accompanying drawing illustrates:
A kind of beams of concrete of Fig. 1: this utility model and the connection node device schematic diagram of steel core concrete column；
A kind of beams of concrete of Fig. 2: this utility model cuts open schematic diagram with the connection node device of steel core concrete column.
Detailed description of the invention:
In conjunction with accompanying drawing, further describe, see accompanying drawing 1 and accompanying drawing 2, visible a kind of beams of concrete and the connection node device of steel core concrete column, it is connected at node with beams of concrete 8 at steel pipe column 7 and a Variable Section Steel bracket 9 is set, the thicker one end of Variable Section Steel bracket 9 is welded on steel pipe column 7, the interior stiffener 2 in Variable Section Steel bracket 9 top flange plate 4 and bottom wing listrium 3 correspondence position welded still pipe of steel pipe column 7, Variable Section Steel bracket 9 opposite side top flange plate 4 bending, form cascaded surface, upper cascaded surface welding second row gluten 5, downstairs face welding first row gluten 6, muscle 10 at the bottom of first row is welded on bottom wing listrium 3, bracket web 12 it is provided with in the middle of Variable Section Steel bracket, bracket web 12 is provided with the curved hole of anchor 1 near the side of steel pipe column, muscle 11 at the bottom of second row and other reinforcing bar are curved through the curved hole of anchor 1 anchor.In two blocks of pipes, stiffener 2 is welded in steel pipe 7 inside, concordant with Variable Section Steel bracket 9 top flange plate 4 and bottom wing listrium 3, bears and transmit the beams of concrete 8 internal force by Variable Section Steel bracket 9 transmission；Variable Section Steel bracket 9 bending top flange plate 4 forms cascaded surface, 4 points of two-layers of reinforcing bar and top flange plate are welded, have and bigger be welded to connect area, rather than the single-point of steel bushing connects, it is reduced or avoided as far as possible and punches so that weakening cross section on steel pipe column 7, Variable Section Steel bracket 9 factory is easy to make, still can punch on steel pipe when especially meeting the double arrangement of reinforcement of beams of concrete.This kind of Variable Section Steel bracket connected mode maximum possible can reduce member section, makes full use of space.Ensureing structural safety, on the premise of economical rationality so that processing factory makes simple, job site easy construction.
