Description
Technical field
The utility model relates to a kind of Joint's connection fabrication mode, is specifically related to a kind of assembling Staggered-truss System post and truss Semi-rigid Joints.
Background technology
Staggered truss structure is a kind of new structural systen of research and development under United States Steel Corporation subsidizes in mid-term in 20th century.This structural system basic composition is pillar, plane steel truss and floor plate, and pillar is arranged in the periphery in house, middle without post; Depth of truss is identical with floor height, and length is identical with house width, and truss is supported at both ends on peripheral pillar, and truss is longitudinally arranged every Pin along house, is levels interlaced arrangement along height of house in adjacent colonnade.This structure has rational force path, very large lateral load can be resisted, its each stiffness layer and bearing capacity change even, each yield strength coefficient is roughly equal, avoid because weak floor appears in rigidity or bearing capacity sudden change place, structural plasticity evolution is long, and dissipation energy is many, has good anti-seismic performance.Because truss is arranged every Pin, can provide twice post distance without post large space, therefore, under the prerequisite of satisfied building using function, post distance can be reduced, reduce floor span, have very high economic benefit, relative to conventional steel frames structural system, the steel using amount of staggered truss structure generally can reduce about 30%.
Conventional Staggered-truss System node hinged structures form is that post internal partition formula connects, when chord member of truss stressed larger time, Nodes concrete filled steel tube post jamb can be caused to be pulled up, to cause gusset plate to rupture at weld heat-affected zone.In addition, due to the existence of internal partition, concrete pouring construction is very difficult.
Summary of the invention
The shortcoming existed for prior art and deficiency, the purpose of this utility model is, there is provided a kind of Staggered-truss System post and truss Semi-rigid Joints, this joint structure mode assembling degree is high, and construction speed is fast, can the reduction of erection time, raise labour productivity, Site Welding operation is few, construction by weather and the impact in season little, major part is operated in factory and carries out, and also makes concrete pouring construction become relatively easy simultaneously.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
A kind of staggered truss post and truss Semi-rigid Joints, it is characterized in that, this node comprises at least two outer ring plates, stiffener, the first end plate, the second end plate;
Described concrete filled steel tube column outer wall is fixedly attached to few two outer ring plates;
Be fixedly connected with stiffener between described adjacent outer ring plate, described stiffener is vertical with described adjacent outer ring plate;
Described outer ring plate is fixedly connected with the first described end plate one side with described stiffener;
The first described end plate and the second described superimposed varied rigid link in face, end plate face;
The second described end plate is fixedly connected with described truss.
The utility model also has following technical characterstic:
The described mode that is fixedly connected with is welding;
Described varied rigid link mode is that bolt connects;
At least two described outer ring plates are parallel to each other installation;
Described outer ring plate is rectangular hollow ring flat-plate, and described outer ring plate truss frame for connecting one end width is greater than its excess-three end width.
The Semi-rigid Joints make that the utility model provides has good practicality, is applicable to the building structure of the long and narrow planes such as semi-high-rise housing, hotel, hospital, office building.Its power transmission is clear and definite, simple structure, and the component needed for structure in advance at produce in factory, only can need directly to carry out bolt connection to scene, greatly can reduce construction period, increase work efficiency.

Below in conjunction with drawings and Examples, particular content of the present utility model is described in more detail.
Detailed description of the invention
Joist body bitt in the utility model and truss comprise steel core concrete column, stiffener, outer ring plate, the first end plate, the second end plate and the several part of truss.
The utility model is at steel core concrete column external welding at least two outer ring plates, as shown in Figure 2, described outer ring plate central hollow, extension has one fixed width, larger load can be resisted, one end due to outer ring plate truss frame for connecting needs to bear larger lateral load, the thus width of this side outer ring plate wider (as Fig. 2).On the one hand, greatly can reduce the difficulty of welding internal partition in pipe at steel core concrete column external welding outer ring plate, particularly for the concrete steel column jecket that internal diameter size is less, its effect is more outstanding; On the other hand, this set can reduce concrete pouring construction difficulty, makes the concrete of building more even.
Outer ring plate horizontal parallel is installed, and be fixedly connected with stiffener, and stiffener is vertical with adjacent outer ring plate between adjacent outer ring plate, and outer ring plate becomes the capable component of I-shaped, for enforced loop plane with stiffener entirety.
In addition, truss, by the high strength exploitation between the first end plate 4 and the second end plate 5, is fixed to steel core concrete column side, can avoids Site Welding like this, can greatly reduce site operation intensity by the utility model.Before going to job site, the steel core concrete column part be connected with the first end plate 4 and the truss portion be connected with the second end plate 5 can in advance at produce in factory, during construction, only bolt connection is carried out at the scene of using, splicing lifting, and its assemblingization degree is high, construction speed is fast, can the reduction of erection time, raise the efficiency, have good application prospect.
At the scene in construction, can node number required for reality, reuse the joint structure mode in the utility model.
Specific embodiment:
Below provide specific embodiment of the utility model, it should be noted that, the utility model is not limited to following specific embodiment, and all equivalents done on technical scheme basis all fall into protection domain of the present utility model.
Defer to technique scheme, as shown in Figure 1, a kind of Staggered-truss System post and truss Semi-rigid Joints, comprise wind up node and lower-chord panel point.
The joint structure that winds up comprises the steel core concrete column 2 vertically placed, and the outer ring plate 1 of steel core concrete column 2 external welding three horizontal parallel, weld stiffener 3 between adjacent outer ring plate 1, outer ring plate 1 is vertical with stiffener 3.Stiffener 3 and outer ring plate and 1 first end plate 4 one side are welded to connect, the second end plate 5 and truss end welding.Wherein, the upper chord 6 of truss, brace 7 and montant 8 form right-angled triangle, and rod member junction gusset plate is fixed between two; After chord member one end and brace one end are fixed with gusset plate, this channel floor is connected with the second end plate 5 vertical welding.
Lower-chord panel point structure comprises the steel core concrete column 2 vertically placed, and the outer ring plate 1 of steel core concrete column 2 external welding two horizontal parallel, weld stiffener 3 between outer ring plate 1, outer ring plate 1 is vertical with stiffener 3.Stiffener 3 and outer ring plate and 1 first end plate 4 one side are welded to connect, and the second end plate 5 is connected with truss lower chord 9 vertical welding.
Above-described steel core concrete column part of welding with the first end plate 4 and the truss portion welded with the second end plate 5 can in advance at produce in factory, during construction, only with by the superimposed rear high strength exploitation of the first end plate 4 and the second end plate 5 faces, construction can be completed, its power transmission is clear and definite, and assemblingization degree is high, can shorten the building site duration, raise labour efficiency, have good using value.
