Embodiment 3
The invention also provides a kind of RPC cover board method for testing and detecting, comprising the following steps:
RPC cover board face down is horizontally disposed with by S1；
S2, RPC cover board top be arranged compression bar so that compression bar can from the both ends of the length direction of RPC cover board against
In the edge of RPC cover board；
S3 applies pressure straight up in the lower section of RPC cover board using jack, and makes the position of the pressure
At the center of RPC cover board；
S4 increases the pressure, and the pressure between real-time detection jack and RPC cover board by certain loading speed；
And it is kept for 3 minutes when the pressure respectively reaches 0,0.5,1.0,1.2,2.0 times of Eguivalent nodal loads；
S5, when there is the first Crack on RPC cover board, record pressure is cracking load.
Through the above steps, convenient for detecting the cracking load of RPC cover board, it is also possible to measure RPC as needed
The stress condition of the elastic stage of cover board, yielding stage and failure stage.
Destructive process of the RPC cover board in testing inspection is broadly divided into " elasticity-surrender-destruction " three phases, and
And different failure laws is shown in each stage.
Elastic stage: RPC cover board started in a period of time after stress, and load and strain can be undergone linear
Elastic stage, in this stage, strain increase with the linear ratio of the increase of load.When reach capacity elastic strain after, RPC
There is first naked eyes visible crack in cover board bottom, and load at this time is referred to as cracking load.
Yielding stage: after crack occurs in RPC cover board bottom, with being continuously increased for load, the destructive process of RPC cover board
Enter yielding stage immediately.In the stage, the advancing the speed much larger than load of advancing the speed of strain, rather than the line of elastic stage
Sexual intercourse.Due to the presence of steel fibre, the yielding stage of RPC cover board is clearly distinguishable from the brittle break process of normal concrete,
And it is very much like with the yielding stage of steel, this has also embodied the superior toughness of RPC cover board.When load increases to ultimate load
Afterwards, RPC cover board loses bearing capacity, and yielding stage terminates.
Failure stage: in failure stage, steel fibre end is separated with RPC cover board, and RPC cover board serious cracking is not so that can
It works normally, shows as that RPC cover board persistently cracks and load does not increase.
