Description
Technical field
This utility model belongs to structural engineering technical field, particularly relates to a kind of through node of dividing plate connected for rectangular steel-tube concrete column and H girder steel.
Background technology
Concrete filled steel tube fill concrete in steel pipe is constituted, the existence of steel pipe is prevented from concrete premature rupture, concrete existence is prevented from the too early flexing of steel pipe, the two synergism 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 height, plasticity and good toughness, anti-seismic performance be 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 big, node is easy to connect. And the frame structure system that rectangular steel-tube concrete column is formed with girder steel, because horizontal layout is flexible, simple in construction, component are prone to the features such as standardization, speed of application is fast, cost is low, executive information systems has good application prospect, has now been 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 technical regulation " (CECS159:2004) of China recommends includes four kinds: internal partition formula connects, the connection of external fin ring-plate, the board-like connection of outer shroud and diaphragm-through type connection. Four kinds of nodes all have bolt weldering mixed node, i.e. edge of a wing welding, web is with bolts.
But, existing bolted and welded connection node is affected 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, it is possible to avoid the impact of weld seam especially lower flange weld defect. But due to needs processing and construct a large amount of bolt and bolt hole, therefore cost is significantly 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 centering, construction will be very difficult.
Summary of the invention

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 is provided with circumferential body and overhanging section wide with the top flange plate of described H girder steel, and the circumferential body of overhanging section of described upper spacer and described upper spacer adopts arc transition structure; Described lower clapboard is provided with circumferential body and overhanging section wide with the bottom wing listrium of described H girder steel, and the circumferential body of overhanging section of described lower clapboard and described lower clapboard adopts arc transition structure.
Described upper spacer is provided with circumferential body and overhanging section wide with the top flange plate of described H girder steel, and the circumferential body of overhanging section of described upper spacer and described upper spacer adopts obtuse angle transition structure; Described lower clapboard is provided with circumferential body and overhanging section wide with the bottom wing listrium of described H girder steel, and the circumferential body of overhanging section of described lower clapboard and described lower clapboard adopts obtuse angle transition structure.
This utility model has the advantage that and has the benefit effect that
1) adopt through upper lower clapboard, increase the rigidity of node area, make plastic hinge, and then make the destruction destruction early than node of girder steel, it is achieved that the antidetonation criterion of " the weak component of strong node ".
2) upper lower clapboard welds with post jamb, it is to avoid the repeatedly welding of post jamb, reduces stress concentration and the fragility of post jamb, improves the ductility of nodes domains.
3) lower flange of H girder steel adopts high-strength bolt to be connected with lower clapboard, decreases the workload of Site Welding, saves manpower, improves site operation efficiency. Lower clapboard extension is big, is connected with girder steel lower flange by high-strength bolt, makes girder steel hogging moment area bearing capacity greatly strengthen; Avoid the adverse effect of lower flange weld defect, it is possible to effectively prevent welding the stress brought and concentrate, it is provided that good anti-seismic performance simultaneously.
4) top flange of H girder steel is welded with upper spacer, and the welding of the web of H girder steel and cantilever plate reduces full bolt and is connected and the risk that girder steel that construction error brings cannot be in place such as tilts or misalign due to post, reduces precision sensitivity, it is possible to quickening installation rate.
5) by the lower flange of H girder steel and lower clapboard link position relationship change, it is possible to form the node of multiple different connected mode, with the satisfied different engineering requirements to joint behavior and node construction mode.
