Description
Technical field
The invention belongs to structural engineering technical field, particularly relate to a kind of through node of dividing plate be connected with H girder steel for rectangular steel-tube concrete column.
Background technology
Encased structures fill concrete in steel pipe is formed, the existence of steel pipe can prevent concrete premature rupture, concrete existence can prevent the too early flexing of steel pipe, the two synergy can give full play to the advantage that steel examining tensile behavior is high and concrete compression performance is good, therefore has that bearing capacity is high, plasticity and good toughness, anti-seismic performance are good, many advantages such as remarkable in economical benefits and construction environmental protection.
Rectangular steel tube with concrete infilled has the advantage that bending rigidity is large, node is easy to connect.And the frame structure system that rectangular steel-tube concrete column and girder steel are formed, because layout is flexible, structure simple, component is easy to the features such as standardization, speed of application is fast, cost is low, there is good application prospect in executive information systems, be now subject to the most attention in domestic and international project field.
At present, rectangular steel-tube concrete column-steel beam connecting joint that " rectangular steel tube with concrete infilled tecnical regulations " (CECS159:2004) of China recommends comprises four kinds: internal partition formula connects, external fin ring-plate connects, the board-like connection of outer shroud is connected with diaphragm-through type.Four kinds of nodes all have bolt to weld mixed node, i.e. edge of a wing welding, web is with bolts.
But existing bolted and welded connection node affects by weld seam, and anti-seismic performance is poor, therefore domestic some propose to adopt full bolt joint.But practical engineering experience shows: full bolt joint stress performance is better, the impact of weld seam especially bottom flange weld defect can be avoided.But due to needs processing and construct a large amount of bolt and bolt hole, therefore cost is very high; And install due to bolt and need longer overhanging dividing plate, therefore to bolt machining accuracy, that on-the-spot beam column installs positioning accuracy request is very high, once column inclination or beam can not centerings, construction will be very difficult.
Summary of the invention
The present invention provides a kind of through node of dividing plate is connected with H girder steel for rectangular steel-tube concrete column for solving in known technology the technical problem that exists, and this node structure is reasonable, easy construction, fast.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is: a kind of through node of dividing plate be connected with H girder steel for rectangular steel-tube concrete column, comprise the upper spacer and lower clapboard that weld with described rectangular steel-tube concrete column, a cantilever plate is respectively welded with in the both sides of described rectangular steel-tube concrete column, described cantilever plate is overlapped on the web of described H girder steel, and the two welds together; Described upper spacer is relative with the top flange plate of described H girder steel, and the two welds together; Bottom wing listrium and the described lower clapboard of described H girder steel overlap, and the two is connected by high-strength bolt.
The bottom wing listrium of described H girder steel is overlapped on described lower clapboard.
Described lower clapboard is overlapped on the bottom wing listrium of described H girder steel.
Described upper spacer be provided with circumferential body and with wide overhanging section of the top flange plate of described H girder steel, overhanging section of described upper spacer adopts arc transition structure with the circumferential body of described upper spacer; Described lower clapboard be provided with circumferential body and with wide overhanging section of the bottom wing listrium of described H girder steel, overhanging section of described lower clapboard adopts arc transition structure with the circumferential body of described lower clapboard.
Described upper spacer be provided with circumferential body and with wide overhanging section of the top flange plate of described H girder steel, overhanging section of described upper spacer adopts obtuse angle transition structure with the circumferential body of described upper spacer; Described lower clapboard be provided with circumferential body and with wide overhanging section of the bottom wing listrium of described H girder steel, overhanging section of described lower clapboard adopts obtuse angle transition structure with the circumferential body of described lower clapboard.
The advantage that the present invention has and good effect are:
1) adopt through upper lower clapboard, increase the rigidity of node area, make plastic hinge, and then make the destruction of destruction early than node of girder steel, achieve the antidetonation criterion of " the weak component of strong node ".
2) upper lower clapboard welds with post jamb, avoids the repeatedly welding of post jamb, and the stress reducing post jamb is concentrated and fragility, improves the ductility of nodes domains.
3) bottom flange of H girder steel adopts high-strength bolt to be connected with lower clapboard, decreases the workload of Site Welding, saves manpower, improve site operation efficiency.Lower clapboard extension is large, is connected, girder steel hogging moment area supporting capacity is greatly strengthened by high-strength bolt with girder steel bottom flange; Avoid the adverse effect of bottom flange weld defect simultaneously, effectively can prevent welding the stress brought and concentrate, good anti-seismic performance is provided.
4) top flange of H girder steel is welded with upper spacer, and web and the cantilever plate of H girder steel weld and reduce full bolt and be connected and the risk that girder steel that construction error brings cannot be in place such as tilt or misalign due to post, reduce precision sensitiveness, can accelerate installation rate.
5) by bottom flange and the lower clapboard link position relationship change of H girder steel, the node of multiple different connected mode can be formed, with the requirement of satisfied different engineering to joint behavior and node construction mode.
