Description
Technical field
The utility model is related to prestressed strand tensioning equipment, especially a kind of prestressed strand stretching bed.
Background technology
Prestressed stretch-draw is exactly to add pulling force in advance in component so that and it is applied in prestressed stretch-draw component and bears tensile stress,
So that it generates certain deformation, to cope with the suffered load of structure itself, including the load of component own wt, wind
Load, snow load, seismic loading etc..Steel strand wires, jack, anchor slab, intermediate plate are used in general tensioning.
Before Engineering Structure Component bears external load, to tension mould steel strand wires in the block, applies compressive pre-stress, improve structure
The bending resistance and rigidity of part postpone the time that crack occurs, increase the durability of component.The tensioning of prestressed strand needs steel
The both ends of beam are carried out at the same time, and traditional method needs constantly to adjust tensioning by manpower, and surrounding does not have enclosing, work
There is security risk in the process, wastes time.
Utility model content
In order to solve the above technical problems, the utility model proposes a kind of simple in structure, safe and efficient Yu Yongli steel beam
Draw platform.
The utility model adopts the following technical solution：
A kind of prestressed strand stretching bed, including stretching bed ontology, stretching bed ontology are the frame structure that square steel is welded into,
The top setting of stretching bed ontology is both provided with slideway on the inside of each cantilever, is equipped between two slideways there are two cantilever
Slide bar；Jack is hung on slide bar；The rear of stretching bed ontology is provided with baffle, and the bottom of stretching bed ontology is provided with bottom plate.
Compared with the prior art, the utility model has the beneficial effects that：
The utility model is simple in structure, being capable of the both ends simultaneous tension of steel beam when tensioning, it is only necessary to which a people is using slideway and pulls
Cucurbit adjusts the upper and lower position of jack, convenient and efficient, significantly saves time and manpower, improves working efficiency.
Further, the preferred embodiment of the utility model is：
Slide bar is set is lifted with pulley by suspension hook, and jack is suspended on by pulley on slide bar.
Description of the drawings：
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Fig. 2 is the side view of Fig. 1；
Fig. 3 is the vertical view of Fig. 1；
In figure：Stretching bed ontology 1；Cantilever 2；Slide bar 3；Pulley 4；Jack 5；Baffle 6；Bottom plate 7；Suspension hook 8；Slideway 9.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and embodiments.
Referring to attached drawing：A kind of prestressed strand stretching bed, including 1 stretching bed ontology 1 of stretching bed ontology are welded into for square steel
Frame structure, the top of stretching bed ontology 1 is welded with the cantilever 2 of two stretching stretching bed ontologies 1, the inside of two cantilevers 2
It is respectively arranged with slideway 9, the both ends of slide bar 3 are separately mounted on the slideway 9 of two cantilevers 2, and jack 5 on slide bar 3 by setting
The pulley 4 set is suspended on slide bar 3；The rear of stretching bed ontology 1 is provided with baffle 6, and the bottom of stretching bed ontology 1 is provided with bottom
Plate 7.
The utility model is in use, respectively hang two prestressed strand stretching beds by hanging apparatus corresponding pre-
Stress steel beam both sides, operator stand in the position of 7 upper edge cantilevered orientation of the bottom plate adjustment slide bar 3 of stretching bed, and adjustment pulley 4 exists
Position on slide bar 3 is adjusted the left and right position of jack 5, and the upper and lower position of jack 5 is then adjusted by pulley 4,
Finally successively to just needing the steel beam of tensioning.
In stretching process, baffle shields to operator, it is only necessary to which a people utilizes slideway and pulley energy
The position of enough easily adjustment jack, is not required to again additional personnel, saves the time that repeatedly adjustment jack is wasted, tensioning
All tools are all placed on the bottom plate of stretching bed in journey, need integrally to hang away when the next position of tensioning.
The above is only the specific embodiments of the utility model, and the protection of single the utility model is without being limited thereto, any skill
The technical staff in art field the thinkable variation being equal with the technical program technical characteristic or replacement, all cover in this practicality
Within novel protection domain.
Claims (2)
