Description
Technical field
This utility model relates to building structure technology field, more specifically to a kind of novel steel-enclosed concrete members combination beam-steel pipe column connected node produced for architectural industrialization.
Background technology
The existing steel-enclosed concrete members combination beam-steel tubular column joints being applied to building structure field mainly has following several form: (1) connections with exterior diaphragms: arrange enforced loop plane outside the steel pipe column of combination beam base plate corresponding position, the overlap welding therewith of combination beam base plate, combination beam side plate directly welds with steel pipe walls, two kinds of structural forms are specifically had for the process of negative reinforcement in combination beam, a kind of by perforate on steel pipe post jamb, in combination beam, negative reinforcement passes and through node area in hole；Negative reinforcement is then disconnected by another kind of structural form in node area, and by welding outer annular-stiffer plate in steel pipe post jamb negative reinforcement position, negative reinforcement welds therewith and realizes power transmission.(2) " shoulder pole " type node: outer annular-stiffer plate is set outside the steel pipe column of combination beam base plate corresponding position, the overlap welding therewith of combination beam base plate, combination beam side plate directly welds with steel pipe walls, and resist hogging moment by arranging the steel plate of " shoulder pole " type in nodes domains, this steel plate side is welded on the overhanging edge of a wing of U-shaped girder steel, and opposite side welds with steel pipe post jamb；(3) reinforced bar sleeve type node: be respectively welded some sleeves along the opposite end of combination beam length direction at steel pipe post jamb, in order to connect end, hogging moment area reinforcing bar, part negative reinforcement can be simultaneously by the through node area, hole on steel pipe post jamb, when whole negative reinforcements are by sleeve connection, steel pipe inner wall corresponding position arranges internal partition as stiffener.
Outer heavier-duty node welds reinforcing ring due to needs outside steel pipe post jamb, can be in the obvious salient angle of indoor generation, affect attractive in appearance, the solder design of the overlap welding of girder steel base plate and enforced loop plane and side plate and steel pipe post jamb, the workload and the weldquality that add Site Welding should not ensure, are unfavorable for that realizing industrialization produces.When cancelling upper enforced loop plane, when using reinforcing bar through outer annular-stiffer gusset-type joint, owing to steel pipe post jamb perforate exists certain weakening to steel pipe column, need to take corresponding reinforcement measure, not only increase difficulty of construction and also can cause the increase of steel using amount." shoulder pole " type node has higher bearing capacity, and power transmission is the clearest and the most definite, but joint form exists hidden danger when pouring node region concrete, and if do not dealt carefully with, then construction quality is difficult to ensure that.Meanwhile, under reciprocating load, hogging moment area steel plate is easily and concrete slab produces bigger Relative sliding, and energy-dissipating property is poor.And reinforced bar sleeve type connection with inner diaphragm, when negative reinforcement is all connected with post jamb by reinforced bar sleeve, it is possible to prevent the weakening to steel pipe post jamb due to perforate, but the setting of sleeve adds somewhat to difficulty of construction and cost.
Utility model content
The post jamb perforate existed for above-mentioned steel-enclosed concrete members combination beam and steel pipe column connected node easily weakens steel pipe column cross section, outer annular-stiffer project rings attractive in appearance, girder steel welds with post jamb and connecting plate so that problems such as the big quality of Site Welding workload should not ensure, propose a kind of novel simple structure, power transmission clearly, easy construction, it is simple to the node of the novel steel-enclosed concrete members combination beam-steel pipe column of industrialized production.
In order to realize above-mentioned technical purpose, this utility model adopts the following technical scheme that: a kind of steel-enclosed concrete members combination beam-steel pipe column connected node, include upper and lower through dividing plate, steel pipe column and laterally attached plate, described upper and lower through dividing plate extends transversely through and is arranged on steel pipe column, negative reinforcement is connected on described through dividing plate, under described, through dividing plate and laterally attached plate form U-shaped single unit system in steel pipe column both sides, described beams encased in steel hoops is positioned in U-shaped single unit system, described upper and lower through dividing plate, is above both provided with pouring hole and air-vent.
Further, described steel pipe column is wide with combination beam beams encased in steel hoops cross section, described under through dividing plate and laterally attached plate form uiform section U-shaped single unit system in steel pipe column both sides.
Further, the difference of described steel pipe column cross-sectional width and combination beam beams encased in steel hoops cross-sectional width more than or equal to 50mm, described under through dividing plate and laterally attached plate form variable cross-section U-shaped single unit system in steel pipe column both sides.
Further, the C-shaped that cross section is top flange varus of described combination beam beams encased in steel hoops or the hat turned up in top flange.
Further, it is connected by high-strength bolt between base plate and coxostermum with the base plate of U-shaped single unit system and the laterally attached plate of described combination beam beams encased in steel hoops.
Further, described through dividing plate is welded to connect with negative reinforcement.
Further, described steel pipe column is steel core concrete column or empty steel pipe column.
Further, the beams encased in steel hoops of described combination beam and the material of steel pipe column are general steel plate or checkered steel plate.
Technical characterstic of the present utility model and effect be:
Under through dividing plate and laterally attached plate form overall U-shaped device in post side, during site operation, beams encased in steel hoops directly places its interior and for beam column connection, integral solder work can complete in factory, beams encased in steel hoops base plate is all connected with laterally attached plate or dividing plate by high-strength bolt with side plate, greatly reduce Site Welding workload, it is simple to construct and realize assemblingization；Negative reinforcement is directly welded on the through dividing plate in upside, it is possible to reduce perforate on steel pipe sidewall and the weakening to steel pipe bearing capacity that causes, and can weld double reinforcing bar as required in the upper and lower both sides of dividing plate；At corresponding negative reinforcement link position corresponding to beams encased in steel hoops base plate, through dividing plate is set, solve the overhanging problem causing chamber interior to have an obvious salient angle and to affect that house uses of outer annular-stiffer, being simultaneously used for the connection of beam column and the transmission of power, power transmission is clear and definite, and concreting is convenient.
