Abstract
The utility model discloses a safety protection device for a prestressed tensioning anchoring end, which comprises a protective cover. The protective cover is n-shaped, two ends of the protective cover are respectively mounted at ends of a component by bolts, a prestressed reinforcing steel bar is mounted inside the component, an anti-collision plate and a damping plate are disposed inside the protective cover, the anti-collision plate is close to the end of the prestressed reinforcing steel bar, the damping plate is tightly attached to the inner wall of the protective cover, and both the anti-collision plate and the damping plate are perpendicular to the prestressed reinforcing steel bar. The safety protection device is simple in structure, can effectively prevent the prestressed reinforcing steel bar from being broken and bouncing, and ensures construction safety.
Description
Technical field
The utility model relates to a kind of prestressed reinforcement resilience protector, particularly prestressed stretch-draw anchor end safety guard.
Background technology
In the prestressed, reinforced tension operation process, hold very big energy in the prestressed reinforcement, careless slightly steel wire or steel strand are broken, and huge energy abrupt release must produce very big danger, causes human casualty accident.Existing job site safeguard procedures are the structure end masonry protection wall of prestressed reinforcement to be housed or to pile up sandbag and gripper shoe interior, and not only the scene has high input, and does not have due security protection effect.
Summary of the invention
The purpose of this utility model is to provide a kind of prestressed stretch-draw anchor end safety guard, and it is simple in structure, can prevent effectively that prestressed reinforcement from breaking resilience, guarantees construction safety.
The purpose of this utility model is to realize like this; a kind of prestressed stretch-draw anchor end safety guard; comprise protective cover; protective cover is several fonts; the component ends of prestressed reinforcement is housed in the protective cover two ends are installed in by bolt respectively, Crashworthy plate and vibration damper plate are being set in the protective cover, Crashworthy plate is near the prestressed reinforcement end; vibration damper plate is adjacent to the protective cover inwall, and Crashworthy plate and vibration damper plate are all perpendicular with prestressed reinforcement.
The utility model is simple in structure, by in the prestressed reinforcement end protective cover being installed, can prevent effectively that prestressed reinforcement from breaking resilience, guarantees construction safety.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a plan structure schematic diagram of the present utility model.
The specific embodiment
A kind of prestressed stretch-draw anchor end safety guard as shown in Figure 1, comprises protective cover 5, and protective cover 5 is several fonts, and the component ends of prestressed reinforcement is housed in protective cover 5 two ends are installed in by bolt 2 respectively.Protective cover 5 is made of polyethylene board or steel plate.Crashworthy plate 3 and vibration damper plate 4 are being set in the protective cover 5, and Crashworthy plate 3 is near the prestressed reinforcement end, and vibration damper plate 4 is adjacent to protective cover 5 inwalls.Crashworthy plate 3 and vibration damper plate 4 are all perpendicular with prestressed reinforcement.In the said Crashworthy plate 3 the polyethylene board interlayer is being set, perhaps Crashworthy plate directly is made of polyethylene board; Said vibration damper plate 4 is a rubber tile.Suit damping spring 1 or yielding rubber cover or spring washer on the bolt between protective cover 5 end walls and the said bolt external end head.The diameter of bolt is at least 12mm.The utility model is not limited to described structure, and said Crashworthy plate 3 can also adopt other form of structure, such as all right filled rubber plate in the Crashworthy plate 3, can also fill fine sand etc. in the vibration damper plate 4.Similarly malformation all should fall within the protection domain of the present utility model.The utility model is simple in structure, can prevent effectively that prestressed reinforcement from breaking resilience, guarantees construction safety.
