Description
Technical field
The utility model relates to civil engineering work construction applications, particularly relates to a kind of novel pre-stressed industrial stock ground canopy structure.
Background technology
That steel truss structure is handsome in appearance is generous, brevity and lucidity, structure stress are clear, are applicable to large span and super-span, are widely used in the large-scale public building such as railway terminal, airport and the industrial construction such as large-span industrial building, warehouse.
Traditional trussed construction is due to the impact of deadweight, vertical load and distortion, and its span is limited and economy is poor.Prestressing force concept is introduced on common truss basis, form truss-string-structure, due to prestressed effect, truss produces the prestressing effect of antiarch upwards, can the opposing effectively deadweight contrary with antiarch direction, the vertical forward such as dead load, mobile load load, can depth of truss be reduced, improve structural span, reduce steel using amount.But the prestressing effect of the truss string structure of routine only can resist the effect of forward load, is disadvantageous for reversed loads identical with antiarch direction such as wind suctions, the long span building that wind inhales load control therefore can not be used for.
Adopt truss string structure or common truss as the building of agent structure, the general purlin that adopts is as the supporting member of roofing, and purlin is arranged on winding up of truss.Truss has stronger stable type in own layer, but in out-of-plane less stable.Purlin is beam type flexural member, and general employing square steel or H profile steel, be connected to winding up of truss by purlin holder, very limited to the out-of-plane supporting role of truss, the resistance to overturning of this truss+purlin is poor.Because purlin is flexural member, the span of its less expensive is 5m ~ 8m, and therefore truss clear spacing is also 5 ~ 8m, causes truss very close, and steel amount is very large, less economical, impacts the attractive in appearance of structure simultaneously.
For arch truss, under vertical uniform load q, there is huge horizontal thrust in its truss support place, cause substructure and bearing cost high.
Structure and the force way of tension string beam structure and truss string structure are similar, be winded up by stiffening member, flexible cable lower edge, centre connect the structural system formed with strut, strut generation component is upwards made by stretch-draw lower edge high strength drag-line, chord member is caused to produce the internal forces distribution contrary with outside vertical uniform load q, thus reduce the internal force of structure, reduce the distortion of structure.The prestressing effect of conventional beam string only can resist the effect of forward load, is disadvantageous for reversed loads identical with antiarch direction such as wind suctions.Because beam string winds up as single rod member, its out of plane stiffness is very weak, and stability is very poor.
Utility model content
The utility model proposes a kind of combined structure system prestressed steel truss and Spatial beam string structure being carried out combine, what the traditional form that effective solution truss string structure adds purlin caused be not highly resistant to, and wind inhales load, resistance to overturning is poor, truss space is close, steel using amount is large, arch truss bearing thrust large etc. shortcoming.
Concrete solution is: the utility model discloses a kind of novel pre-stressed industrial stock ground canopy structure, comprise and being made up of the many Pin prestressed steel truss be laterally arranged in parallel and longitudinal multiple tracks Spatial beam string structure arranged, described prestressed steel truss and Spatial beam string structure are interconnected and form overall integral structure.
Further, prestressed steel truss comprise winded up by truss, steel truss agent structure that truss lower edge, truss web are formed, truss winds up, truss lower edge and truss web are mutually permanently connected, also comprise last quarter rope, strut, hound, suspension cable, strut and truss lower edge are articulated and connected, and last quarter rope is connected by rope bar connected node with strut, and the end of last quarter rope is connected with truss lower edge, by stretch-draw last quarter rope to structure Shi Hanzhang, make truss generation antiarch upwards; One end of suspension cable is connected with truss lower edge, and the other end is connected on the truss rope bar tie point of last quarter rope, strut, hound, by giving suspension cable Shi Hanzhang, makes structure produce downward effect.
Further, steel truss agent structure is quadrangle truss or triangular truss; Steel truss agent structure adopts related subgroup truss or solder sphere truss.
Further, in the peak of the arc formed of prestressed steel truss, lower oblique cord and stress steel truss junction and arrange longitudinal stability truss close to the position at two ends.
Further, Spatial beam string structure is made up of the beam that winds up, the web member that winds up, triangle strut, upper suspension cable, jump stay, lower suspension cable; Two wind up beam and the web member formation plane frames that wind up; Upper suspension cable, jump stay and triangle strut produce prestressing effect upwards to the beam that winds up, and form the tension string beam structure with carrying forward load; Upper suspension cable is connected by the beam rope bar tie point that winds up with triangle strut, lower suspension cable one end is connected on the truss lower edge of truss, the other end is connected with triangle strut, upper suspension cable, jump stay by beam string rope bar tie point, by oblique pull under stretch-draw, formed and there is the tension string beam structure carrying reverse wind load.
The upper suspension cable of Spatial beam string structure and the beam that winds up, to be winded up with the truss of prestressed steel truss by connected node and be connected, the lower suspension cable of Spatial beam string structure is connected with the truss lower edge of prestressed steel truss.
Beneficial effect:
Different from the Earthquake response of traditional truss+purlin, a kind of combined structure system prestressed steel truss and Spatial beam string structure being carried out combine, prestressed steel truss and space are opened string two combine, form a kind of interactional new structural systen, improve stability and the supporting capacity of structure.The last quarter rope of prestressed steel truss structure, strut and truss acting in conjunction form truss string structure, and can resist vertical uniform load q, suspension cable can resist reverse wind load, can reduce the horizontal force of bearing simultaneously.
Spatial Beam String Structure is arranged between two Pin steel trusss, and its power transmission effect is identical with main purlin.Because Spatial Beam String Structure all has effective supporting capacity to plane internal loading peace the curved beam, simultaneously due to the existence of lower suspension cable, be highly resistant to reverse wind and inhale load.Adopt Spatial beam string structure to replace common purlin, change tradition into prestressing force beam string structure, significantly can increase span compared with common purlin, make the span of purlin increase to 20 ~ 40m by 5 ~ 8m by curved purlin, that reduces purlin uses material usage.Due to purlin across increase, the distance between adjacent two Pin steel trusss is increased, and then reduces the quantity of steel truss, reduce the material usage of steel truss.Spatially the upper suspension cable of beam string structure and the end of beam are connected to winding up of truss, and lower suspension cable is connected with the lower-chord panel point of trussed construction, and each node that truss is winded up has a side direction fulcrum, can improve the resistance to overturning of truss.Spatial beam string structure and prestressed steel truss are combined, gives full play to the advantage of each self-structure, building structure can be made in moulding, usage space, cost, difficulty of construction, manufacture and transport to reach optimum.
For the closed transformation in the stock ground of the outdoor coal yard in the coal-burning power plant runed, iron and steel works, adopt the utility model can adopt the construction method of packet slip, do not affect stock ground equipment in construction process and run, equipment is without the need to transformation, factory, without the need to stopping work, can reduce cost, reduces the wasting of resources.
