Description
Technical field
The present invention relates to a kind of concrete-bridge, more particularly to a kind of concrete-bridge bracing means.
Background technology
Concrete has the characteristics that abundant raw material, cheap, compression strength is high, thus makes its dosage increasing.Steel
Reinforced concrete bridge is the primary structure form of current bridge.But concrete material resists in itself there is dry shrinkage and cracking is easy to
The defects such as tensile strength is low, cause concrete-bridge to occur a large amount of disease bridges during later stage use, and produce bridge crack
It is wherein one of Major Diseases reason, crack Producing reason is varied, is broadly divided into thermal cracking, desciccation crack and external force
Caused three kinds of crack, reason are mainly that the ground under structure and component produces differential settlement；Template, the no fix tightly of support
Gu；Concrete is subject to high vibration during form removal；Environment or concrete surface and internal difference in temperature are excessive；Concrete curing it is bad and its
Middle moisture evaporation is too fast etc..
There is the bracing means of a variety of concrete-bridges at present, still, current bracing means has the following disadvantages：1、
Can not Fast Installation, especially for some bridges, crack is more, great in constructing amount, and in-site installation bracing means is time-consuming and laborious, especially
It is the geographical location not very big in-site installation of suitable services amount of some bridges；2nd, can not be big according to crack using dumb
Ditty regulating device, causes bracing means purposes single.Therefore, it is necessary to it is a kind of can quickly reinforcement bridge crackle new reinforcing
Device.
The content of the invention
Goal of the invention：The present invention provides one kind can Fast Installation, the adjustable bridge strengthening device of size.
Technical solution：To solve the above-mentioned problems, the bracing means of a kind of concrete-bridge crackle of the present invention, comprising
Fixed body, bent stick and installed part；The bent stick is arranged on the fixed body both ends, fixed body respectively by the first nut with
Bent stick one end connects, and the bent stick other end is connected by the second nut with installed part.First nut is rotatable with bent stick
Connection, is fixed, rotating nuts, that is, adjustable-tightness, draw crackle over to one's side, make its closure, prevent from extending again with adjusting rod.
The fixed body includes cartridge type casing and adjusting rod, and cartridge type casing is threadedly coupled with adjusting rod, and cartridge type casing includes
There is internal thread, adjusting rod one end has the rotation screw thread that internal thread matches, tight by the internal thread and cartridge type casing of cartridge type casing
It is solidly connected；The adjusting rod is external thread type, and respectively left-right rotary screw thread, can be fixedly connected with cartridge type casing, to adjust pine
Tightly, crackle is drawn over to one's side.
The installed part is to include sequentially connected bolt, tube expansion, hex nut, spring washer and plain washer, installed part
Formed and be detachably connected with the second nut.The installed part is arranged on the upper surface of Bridge Crack, with Bridge Crack notch both sides
Road bed is fixedly connected；
Keyway is contained at the bent stick both ends, prevents the first nut and the second nut axial displacement, it is allowed to the positioning of nut
Rotation, limits nut axial displacement.
The bent stick and adjusting rod are carbon fiber bar.
The bent stick is in 90 ° of bendings.
In order to make the present invention have more preferable use scope, when the crack of bridge is larger, bracing means may be provided with anchor
Bar, anchor pole one end are fixed among cartridge type casing；It is detachably connected between anchor pole and cartridge type casing for screw thread.The anchor pole is another
End extends to Slit bottom.Anchor pole can play more preferable supporting role with fracture.
When crack is larger, reinforcing rib can be further welded with anchor pole.
The reinforcing rib includes some horizontal bars and some longitudinal ribs.
The transverse direction is vertical with anchor pole, horizontal bar equidistant arrangement；The longitudinal rib is equidistantly arranged with anchor pole parallel longitudinal direction muscle
Row.
When crack is larger, by the device of the invention, anchor pole and reinforcing rib, and the concrete perfusion in crack are added,
Crack can be further repaired, increases the use scope of bridge.
Beneficial effect：This concrete-bridge crackle bracing means, it is simple in structure, be conducive to largely standardization production.This adds
It is fixedly mounted with and puts with good reinforcement performance, bridge crack can be carried out easily and fast and fixed.Its own structure is very firm, peace
It is time saving and energy saving to fill, and whole implementation process safety is convenient.Suitable for the reinforcing to concrete-bridge crackle.The device is particularly suitable for
The less bridge plate of crackle, easy for construction, cost is relatively low.

Embodiment
Embodiment 1：As Fig. 1 and Fig. 2 are shown, a kind of bracing means of concrete-bridge crackle of the present invention, comprising solid
Determine body, bent stick 1 and installed part, bent stick 1 is arranged on fixed body both ends, and fixed body passes through the first nut 3 and bent stick respectively
1 one end connects, and 1 other end of bent stick is connected by the second nut 4 with installed part 2.As shown in figure 3, bent stick is in 90 ° of bendings.
As shown in figure 4, keyway is contained at bent stick both ends, it is allowed to which the position rotating of the first nut 3 and the second nut 4, keyway are used to limit
Nut axial displacement.Installed part is by sequentially connected bolt 21, tube expansion 22, hex nut 23, spring washer 24 and plain washer 25
Composition, forms with the second nut 4 and is detachably connected, in the present embodiment, installed part is expansion bolt, and installed part is in Bridge Crack
