Abstract
The utility model is related to a kind of prestress wire tensioning security protection body, solving existing steel strand tension is protected by placing plank at jack rear, plank stability is poor, easily go down, the relatively low defect of protective capacities, protection body is built into space framework by channel-section steel, it is an opening stretched into for steel strand wires before space framework, remaining tilts by angle steel be connected and formed closed sideways, protection body is just to the structure being superimposed behind steel strand tension jack using plank and steel plate, and the two sides of protection body are fixed with color steel tile.Protection body uses stereochemical structure, good stability, and protection body for opening for steel strand wires except above stretching into, and remaining is closing and plays protective action, the scope increase of protection sideways, it is to avoid topples over during intermediate plate ejection impact, protective capacities is higher.
Description
Technical field
The utility model is related to a kind of safeguard structure, especially a kind of prestress wire tensioning security protection body.
Background technology
Steel strand wires are a kind of load parts for bearing ton active force, are mainly twisted steel by jack when tensioning
Thread end is clamped in anchorage, when jack is stretched, can produce larger active force, therefore steel strand tension is needed
Higher security protection.
But existing steel strand tension is simply positioned over after jack with one piece of plank, stops possibility by plank
The intermediate plate of generation is flown, it is to avoid intermediate plate causes personal safety accident to surrounding ejection.
But this plank is all interim placement, stability is bad, is flown out once accident intermediate plate occurs in tensioning, plank is easy
Go down, protective capacities declines, and intermediate plate stopped by plank after can change and fly direction, accident when causing more serious.It is existing
The placement location of some planks so that when intermediate plate flies out, plank can not ensure the safety in both sides direction.
The content of the invention
The utility model, which solves existing steel strand tension, to be protected by placing plank at jack rear, plank
Stability is poor, easily goes down, and there is provided a kind of prestress wire tensioning security protection body, energy for the relatively low defect of protective capacities
Larger impulsive force is born, will not be knocked down by intermediate plate, protective capacities is preferable.
The utility model also solves existing steel strand tension by plank to protect, it is impossible to ensure on the direction of both sides
The defect of safety is there is provided a kind of prestress wire tensioning security protection body, in addition to jack rear, also on the direction of both sides
Protection, protection face is wider.
The utility model solves the technical scheme that its technical problem used：A kind of prestress wire tensioning is anti-safely
Watch box, it is an opening stretched into for steel strand wires that protection body is built into before space framework, space framework by channel-section steel, and remaining is sideways
Tilted by angle steel and be connected and formed closed, protection body is just to using plank and steel behind steel strand tension jack
The structure that plate is superimposed, the two sides of protection body are fixed with color steel tile.Protection body uses stereochemical structure, good stability, protection body
Except above being stretched into for opening for steel strand wires, remaining is closing and plays protective action sideways, and the scope increase of protection is kept away
Exempt to topple over during intermediate plate ejection impact, protective capacities is higher.
Preferably, protection body has a top, the length at top is more than the length of protection body side surface, and top exceeds side
Facial position forms top eaves.
Preferably, the top of protection body and the vertical channel-section steel of space framework are mutually fixed, and consolidated by the angle steel tilted
Fixed connection, top uses color steel tile.
Preferably, top, which is connected with protection body movement suspention chain, top, is connected with traction cucurbit.
Preferably, plank behind protection body is list structure, polylith plank is formed side by side, per fast plank with channel-section steel and
Fixation is bolted between corresponding angle steel.
Preferably, leaving gap between adjacent plank, clearance control is in 2-10mm.
Preferably, the thickness of plank is 20mm, steel plate is printed steel plate, and the thickness of printed steel plate is 5mm.
Preferably, being lined with steel wire between the back side of plank and steel plate.
The beneficial effects of the utility model are：Protection body uses stereochemical structure, good stability, and protection body is except being above spacious
Mouth is stretched into for steel strand wires, and remaining is closing and plays protective action, the scope increase of protection sideways, it is to avoid intermediate plate ejection punching
Topple over when hitting, protective capacities is higher.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the utility model；
Fig. 2 is a kind of side view of the utility model；
In figure：1st, color steel tile, 2, angle steel, 3, transverse channel steels, 4, plank, 5, top, 6, suspention chain, 7, top eaves, 8, vertical
Channel-section steel, 9, steel plate.
Embodiment
Below by specific embodiment, and with reference to accompanying drawing, the technical solution of the utility model is made more specifically
It is bright.
Embodiment：A kind of prestress wire tensioning security protection body（Referring to Fig. 1 Fig. 2）, overall is in cubic, including
It is opening before the space framework built by transverse channel steels 3 and vertical channel-section steel 8, space framework, is stretched for steel strand wires end
Enter and carry out tensioning in protection body by jack, the two sides of space framework and be closed below.Two sides and below
On transverse channel steels be many, be parallel to each other, the end of transverse channel steels is mutually fixed with vertical channel-section steel.Adjacent two channel-section steel in same side
Between connect inclined angle steel 2, bottom and top two corners steel angle of inclination is opposite.Protection body behind steel strand tension jack just to adopting
The structure being superimposed with plank 4 and steel plate 9, the two sides of protection body are fixed with color steel tile 1.Plank is list structure, polylith wood
Plate is formed side by side, every to be bolted fixation between fast plank and channel-section steel and corresponding angle steel.Between being left between adjacent plank
Gap, clearance control is in 5mm.The thickness of plank is 20mm, and steel plate is printed steel plate, and the thickness of printed steel plate is 5mm.
Protection body has a top 5, and the length at top is more than the length of protection body side surface, and top exceeds sideway stance shape
Into top eaves 7.The top of protection body and the vertical channel-section steel of space framework are mutually fixed, and are fixedly connected by the angle steel tilted, top
Portion uses color steel tile.Top is connected with protection body movement suspention chain 6, top and is connected with traction cucurbit.
When steel strand wires need tensioning, protection body is hung to tensioning position, the tensioning of steel strand wires end connection by door machine
Jack is extend into protection body.
Embodiment described above is a kind of preferred version of the present utility model, not makees any shape to the utility model
Limitation in formula, also has other variants and remodeling on the premise of without departing from the technical scheme described in claim.
