Description
Technical field
Concrete test block compression test field is the utility model is related to, it is more particularly to a kind of to be used for concrete test block resistance to compression examination
The protector tested.
Background technology
In order to determine concrete compressive ultimate strength, to determine the strength grade of concrete, as evaluation concrete quality
Index, people often do concrete test block compression test in construction period.Compression test needs to use compression testing machine or ten thousand
Can testing machine, compression testing machine and universal testing machine include base and top plate, top plate be respectively arranged on the base with top board
And lower platen, between concrete test block is placed in into upper lower platen, and one of keep in top board and lower platen static, move
Dynamic another part makes lower platen adjacent to each other, so as to give concrete test block provide a pressure, until concrete test block by should
Power is destroyed.
During experiment, along with the increase of pressure, the pressure that concrete test block is born is increasing, easily goes out
Existing concrete test block bursts apart, and rubble to be splashed from the concrete test block to burst apart etc. easily triggers security incident.In order to avoid peace
The generation of full accident, people would generally do some protection in the test block rest area of concrete test block testing machine and set, and avoid coagulation
Native test block, which is burst apart, triggers security incident.
Authorization Notice No. is CN201819842U, and authorized announcement date is that the Chinese patent of on 05 04th, 2011 discloses one
Kind cracking prevention device for high-strength concrete compression strength testing, it includes a protection cylinder, and it includes an energy with fold freely
Flexible rubber shroud, it is sleeved in protection cylinder；One suction sheet, it is one and is arranged on through magnetized on rubber shroud
Iron plate.
At work, protection cylinder and rubber shroud are placed in outside concrete sample for existing protector, are put in pressure in the lump
On the lower platen of force tester, pressure testing machine is started, forcing press lower platen rises, when concrete sample rises to certain altitude
When, suction sheet is fixed by magnetic force and the absorption of forcing press top board, while forcing press top board promotes suction sheet and with fold
The rubber shroud that can freely stretch be vertically lowered, until top board completely attaches to concrete sample upper surface and test specimen is pressurized.
In the protector that protection cylinder and rubber shroud collectively form in said structure, only it is provided with protection cylinder and is used for inspection section inside information
The hole of condition, in order to realize protection effect, the diameter in the hole in protection cylinder should be as far as possible small, and such setting is unfavorable for resisting
The observation of the situation of change of concrete test block during pressure experiment.
Utility model content
The purpose of this utility model is to provide a kind of protector for concrete test block compression test, and it passes through protection
The setting of door, while protection is provided to compression test, the observation to compression test process can be facilitated.
Above-mentioned technical purpose of the present utility model technical scheme is that：
