Description
Technical field
It the utility model is related to building ground technical field of structures；More particularly to a kind of concrete ground surface expansion joint power transmission
Structure.
Background technology
Modern industry factory building requires more and more higher to flatness, the crack resistance of Ground, and especially large area is held
Heavy industry facility floor, due to being frequently necessary to the load-bearing that is open to traffic, therefore the concrete ground for typically using concrete cement to pour.But factory building
Face is general wider larger, and cement flooring area it is larger after would generally cause Ground Ruptures due to the dilatation of itself, therefore one
As usually require concrete ground distributor forming expansion joint between adjacent isles every in fritter.
But the presence at expansion joint destroys the globality on road surface.To ensure the Load-transfer Capacity of seam, load-bearing concrete
Horizontal loading is delivered to another block of plate, so as to improve isolation by face by setting load transfer device at expansion joint from plot face
The supporting situation of tape edge edge, the appearance for preventing faulting of slab ends.
Existing ground load transfer device, usually using dowel bar structure, i.e., surface expansion joint side is vertically fixed in concrete
Transmission rod is set, and transmission rod is typically obtained using round steel, and the transmission rod other end is slidably fit into expansion joint opposite side side
On hole in, transmission rod is arranged as multiple along expansion joint length direction uniform intervals.So, can either by transmission rod
Ensure the Telescopic at expansion joint, and can enough transmits horizontal loading to protect expansion joint.In cement concrete pavement engineering, state
Outer various Seam failure prediction models show whether abutment joint fragmentation influences maximum for the setting of transmission rod, after transmission rod is set, road
Face total cost increases 5%-8%, but the seam life-span can double the above, it is seen that the setting of transmission rod has aobvious to the raising seam life-span
Write effect.

Transmission rod is the unilateral setting of ahead running line direction.The general width of large-area concrete ground is big, can deposit in the two directions every
Gap.Concrete floor if only unidirectionally setting transmission rod, can not meet the freedom of other direction when affected by environment flexible
It is flexible；If in two-way setting transmission rod, in the two-way transmission rod of plate edge stretching restriction plate, larger answer is produced
Power, and then crack is produced, or because the load that plate is born is different, plate is different from the frictional resistance of basic unit, local environment
Difference, and the influence of other restraining forces, the telescopic direction between adjacent plate may be caused different, after transmission rod confined shrinkage,
Larger stress can be equally produced, and then produces crack.
The installation quality of other transmission rod requires high, and it can be seen from the function of transmission rod, every transmission rod must be vertical
It is parallel with horizontal direction with telescopic direction.If there is not parallel situation, flexible resistance can be increased, stretch limitation when serious
Contracting, crack is produced in other weakness when stress is excessive in plate.Cement concrete pavement construction width it is certain, can framing construction,
Single construction transverse joint is short, and has special transmission rod support, sets transmission rod to have special device in paver at non-construction joint,
Transmission rod direction and quality are easily controllable.In large-area concrete ground construction, single construction concrete floor area is big, stretches
Contracting seam length, transmission rod quantity is more, in installation process, in concreting process, in process of vibrating, is likely to make transmission rod
Displacement, either vertical or horizontal shift can all produce flexible resistance, and transmission rod quantity will cause accumulative flexible resistance big more,
And then it is extremely difficult to ideal effect.
