Description
Technical field
This utility model relates to bridge building materials technology field, is specifically related to a kind of bridge concrete protective layer cushion block.
Background technology
Concrete cover refers in concrete structure member, and the outer rim of steel bar stress outermost layer reinforcing bar is to concrete surface
Between concrete layer, be called for short protective layer.For bridge structure, steel reinforced concrete protective layer thickness is to be related to bridge make
By one of the deciding factor in life-span.And the making of protective layer cushion block and select be thickness control of protection cover of rebar key it
One, protective layer cushion block location is the most important thing during whole protective layer controls simultaneously.
Concrete protective layer pad mainly has following several respects effect in bridge construction industry: 1, bear External Force Acting,
Protective layer has anchor force to reinforcing bar, utilizes the anchor force between concrete and rebar, and both combine closely, and jointly participates in work；Protect
Sheath cross thin or disappearance time, reduce it anchor force thus reduce structure support axial force-resisting and the effect of moment of flexure.
2, flameproof protection layer concrete has certain heat-blocking action, can carry out the reinforcing bar being easier to soften when running into fire
Protection, if protective layer thickness is the thinnest, the most easily ftractures, causes reinforcing bar to reduce intensity because of overheated thus destroy
Overall structure.
3, the thinnest wet gas and the water of easily infiltrating into of protective layer in enclosed structure durability concrete, blocked up, is easily generated and splits
Seam, these all may make steel bar corrosion and expand, so that concrete wrecks, impact uses and structural safety.
In xoncrete structure, the composite that armored concrete is made up of reinforcing bar and two kinds of different materials of concrete, two
Plant material and there is good adhesive property.In order to ensure reinforcing bar and concrete cooperation about, reinforcing bar is made to give full play to meter
Calculate desirable strength, need from reinforcing bar bond-anchorage angle, concrete cover to be claimed.Protect at pouring reinforcement concrete
In the work of layer, for indispensable during the use of cushion block.For cushion block, should possess enough intensity, the most broken,
Corrosion-resistant and be of the required size.If cushion block is well combined with concrete, harmomegathus performance is close, simple with bar connecting,
Energy self-locking, does not falls off；And if cushion block is combined bad with concrete, or harmomegathus performance difference is too many, is easy for around cushion block
Produce crack the most easily to come off, so that becoming strength weak link at cushion block.
The concrete protective layer pad used during bridge construction at present tends in actual applications to be occurred
The phenomenon that adjacent pod is mutually disengaged, makes the connection reliability between cushion block and stability reduce, and then affects the use of bridge
Life-span.
Utility model content
This utility model is aiming at the problem that current protective layer cushion block reliability and stability aspect exists, and proposes one
Bridge concrete protective layer cushion block, intermediate portion is divided into conical design, and two ends are circular tray designs, increase effectively cushion block body with
The contact area of concrete；It has the tied silk design being easy to fixing reinforcing bar, can effectively provide self-lock ability, set inside cushion block
It is equipped with steel bar framework so that the structural strength of cushion block improves further.
The technical scheme that the above-mentioned technical problem of this utility model solution is used is: a kind of bridge concrete protective layer pad
Block, including: cushion block body, lower disc, upper disk, cone, build platform, steel bar groove, tied silk, tied silk hole, tied silk fix seat, cuff, steel
Muscle and steel reinforcement cage, described cushion block body includes lower disc, upper disk and cone, and described lower disc is bracket, and cone is sandwiched in lower disc
And between upper disk, described upper disk having poured and has built platform, building platform is the cylinder that top has arch steel groove, described reinforcing bar
The both sides of groove are provided with tied silk and fix seat, and tied silk is fixed and dug tied silk hole on seat, and described tied silk is fixed on tied silk through tied silk hole
On fixing seat, described tied silk is cased with one group of cuff；Reinforcing bar has also been inserted inside the cone of described cushion block body, and by multiple steel
Muscle cage connects location, by being welded and fixed between described reinforcing bar and steel reinforcement cage.
This utility model beneficial effect:
1, utility model protection layer cushion block reliability is high, good stability, contributes to promoting bridge service life.
2, the outside disk external diameter surface of this utility model is fillet structure, it is to avoid stress is concentrated and caused material big
Destroy.
3, disk of the present utility model and cone structure design, be not easy to come off, it is possible to effectively protect after pouring protective layer
Protect internal-internal bar construction not corroded by external environment condition, it is to avoid because steel bar corrosion causes overall construction intensity to decline.
4, this utility model is built into bar construction at cushion block and increases substantially overall construction intensity, protects forming concrete
Will not chipping phenomenon after sheath.
5, this utility model overall structure is simple, stability strong, with tied silk and cuff structure, it is possible to make cushion block and reinforcing bar
Between formed locking effect, it is to avoid cushion block because of vibration or other factor generation relative displacements.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of this utility model product.
Fig. 2 is the front view of this utility model product.
Detailed description of the invention
Below in conjunction with Fig. 1 and Fig. 2, this utility model is described in further detail.
A kind of bridge concrete protective layer cushion block, including: cushion block body 1, lower disc 2, upper disk 3, cone 4, build platform 5, steel
Muscle groove 6, tied silk 7, tied silk hole 8, tied silk fix seat 9, cuff 10, reinforcing bar 11 and steel reinforcement cage 12,
Described cushion block body 1 includes lower disc 2, upper disk 3 and cone 4, and described lower disc 2 is bracket, and cone 4 is sandwiched in lower circle
