Description
Technical field
The present invention is the version at a kind of steel crane beam single-column expansion joint.
Background technology
In industrial building, the portal-rigid frames Factory Building having overhead traveling crane is the most universal.Clear stipulaties in specification, all should arrange expansion joint when steel-structure factory building exceedes certain length.And the length of temperature division of Steel Portal Frames (expansion joint spacing) to be longer than normal steel structure Factory Building a lot, the version of double rigid frame is set at expansion joint by normal steel structure Factory Building length of temperature division (expansion joint spacing) under normal circumstances, rigid frame can not give full play to its load-bearing effect, cause the waste of material, increase construction cost, affect construction speed, strengthen investment.
In the present invention, the way easy construction at steel crane beam single-column expansion joint, cost-effective, does not affect construction speed, and malformation is coordinated, and can meet design use requirement completely.
Summary of the invention
The technical problem to be solved is: according to the practical situation of Factory Building, arranges crane girder single-column expansion joint in place.Purpose is cost-effective, and Factory Building is attractive in appearance, reasonable stress.
For solving the problems referred to above, the present invention is achieved in that
A kind of steel crane beam single-column expanded joint structure, including left steel crane beam, right steel crane beam, rigid-frame column, steel corbel, support plate, junction steel plate；The lower flange of described left steel crane beam is connected with rigid-frame column plate bearing；Described left steel crane beam, right steel crane beam top are overlapped by junction steel plate；Described right steel crane beam one end is variable cross-section, and one piece of support plate opening slotted hole is welded in variable cross-section end lower flange, is bolted on the steel corbel that left steel crane beam stretches out by this support plate.
For reducing friction, described support plate underlay sintering polytetrafluoroethylene plate.
For ensureing safety, described right steel crane beam arranges keep plate, described rigid-frame column arranges ribbed stiffener, described keep plate and ribbed stiffener square bar burnished bolt and connects.
Expansion joint width between described left steel crane beam, right steel crane beam is 30-50mm.
Described sintering polytetrafluoroethylene plate thickness is 8-15mm.
1 piece of junction steel plate of the side bar welding of described keep plate, junction steel plate is opened slotted hole plain bolt and is connected with the edge of a wing of rigid-frame column.
Screw and inclined-plane are set on described ribbed stiffener, arranging strip hole (111) on described keep plate, described inclined-plane is corresponding with the inclined-plane of keep plate, and described square bar burnished bolt one end screws in described screw, screw cap end is arranged on outside keep plate, and the bar of described square bar burnished bolt slides in strip hole.
The invention have the advantage that the structural form using a kind of crane girder single-column expansion joint, meet mechanics model, reasonable stress, malformation is coordinated, and cost-effective, Factory Building is attractive in appearance, accelerating construction progress.
