Description
Technical field
The present invention relates to a kind of movable bearing support, belong to steel truss trestle technical field, particularly relate to a kind of steel truss and roll
Bearing
Background technology
Steel truss trestle is a kind of conventional version in DESIGN TREND OF MODERN INDUSTRIAL ARCHITECTURE, as modern plant transportation system
Important component part, carries transport raw material and the task of finished product.In recent years, along with industrial and mining establishment of China construction and send out
Exhibition, steel truss trestle is light with its dead load, the strength of materials is big, many-sided advantage such as good integrity, short construction period, long away from
Being widely used from large span conveying system Construction, especially height is the steel truss trestle of 15～20 meters, possesses
Cost is low, and anti-seismic performance is good, the feature that construction speed is fast, and steel truss trestle increasingly develops to direction big, high, weight.But steel
Truss temperature influence is relatively big, so the bearing of steel truss must is fulfilled for the deformation requirements of temperature influence.
Currently for the solution of steel truss deformation problems, it is to offer elongated hole at base-plate, in order to overcome steel
The displacement that truss lateral expansion causes, but the elliptical aperture that shortcoming needs when to be steel truss longer is relatively big, and between bearing and base plate
For sliding friction, frictional force is very big, unfavorable to structure, after long-time use, potential safety hazard easily occurs.
Summary of the invention
The invention provides a kind of steel truss roller support different from prior art design, in order to solve in prior art
Defect.Avoid the axial horizontal internal force such as the amount of deflection destruction to steel truss produced under temperature, loads change factor, and can
The impact of the opposing transverse horizontal internal force such as wind load, equipment load..
In order to realize the purpose of the present invention, by the following technical solutions:
A kind of steel truss roller support, including roller bearing, described roller bearing is arranged between upper bracket and undersetting, undersetting with
Upper bracket mutually fastens；Described upper bracket includes top board, is respectively mounted the first baffle plate on front side of top board, below rear side, described lower
Seat include base plate, on front side of base plate, back side top be respectively mounted second baffle, the bottom of the first baffle plate, second baffle top equal
Having the loose slot being positioned at same level absolute altitude, the two ends of described roller bearing are respectively provided at 2 set the first baffle plates, the activity of second baffle
In groove.
In order to realize the purpose of the present invention further, it is also possible to by the following technical solutions:
Described roller bearing includes thick roller bearing, and thin roller bearing is installed at thick roller bearing two ends, described thick roller bearing be arranged on 2 set the first baffle plates or
Between second baffle, thick roller bearing periphery and top board, base plate movable contact.
Below described top board and/or base plate is fixed above installs longitudinal third gear plate, third gear plate is arranged on 2 piece first
Between baffle plate or second baffle, described third gear plate is provided with 2 pieces, lays respectively at the both sides of roller bearing.
Described second baffle is arranged between 2 set the first baffle plates.
Described first baffle plate and second baffle are of similar shape structure.
Compared with prior art, the invention have the advantages that
1, the present invention will fix as steel truss and the bearing of supporting role is divided into upper and lower two parts, and installs in centre
Roller bearing, roller bearing two ends are respectively provided in the loose slot of 2 set the first baffle plates, second baffle, therefore, when steel truss trestle is by temperature
Load, seismic (seismal etc. affect, and its thrust can pass to upper bracket top board, and upper bracket is determined plate and transferred load to roller bearing,
Roller bearing passes to undersetting base plate again, and the component such as the support column of undersetting base plate and lower section or bracket is fixed.Owing to roller bearing can be
Move in this bearing so that upper bracket and undersetting relatively move based on roller bearing, for removing the temperature of steel truss trestle
Dilatation under degree change or earthquake sheet and the amount of deflection produced during by load, release length travel change, improve steel truss
The structural safety of frame trestle.Arranging certain spacing between first baffle plate and second baffle, the first baffle plate can be outside second baffle
Side relative movement, therefore while ensureing that this bearing can preferably solve axial horizontal internal force produced by steel truss trestle,
Also there is the effect that can resist the transverse horizontal internal force such as wind load, equipment load.
2, present configuration is simple, and roller bearing and top board, base plate sliding contact, between upper bracket and undersetting, force path is bright
Really, thus preferable structural stability can be kept.
3, with respect to increase basis or use bigger elliptical aperture to realize bearing and the moveable structure of base plate, this
Bearing volume is little, and processing technology is simple, greatly improves speed of application, reduces construction period and the cost of steel truss.
4, by arranging various sizes of loose slot and rolling shaft structure, make to present invention can be suitably applied under different types of earthquakes
Loading demands.
