Abstract

The invention relates to the field of engineering test equipment, in particular to a prefabricated cement board compression testing machine which comprises a hollow machine body, a test bed used for placing a cement board sample is arranged on the machine body, an annular extending edge is arranged on the outer side wall of the test bed in the circumferential direction, and an annular material blocking air bag is arranged on the extending edge. An inflation assembly used for inflating air into the material blocking air bag is further arranged in the machine body, and an exhaust valve used for exhausting the air in the material blocking air bag is arranged on the extending edge. The device has the advantage that the possibility of injury of experimenters caused by burst of cement board samples is reduced.

Description

technical field [0001] The invention relates to the field of engineering test equipment, in particular to a prefabricated cement board compression testing machine. Background technique [0002] Prefabricated cement board is a kind of building slab produced in advance in the factory with cement as the main raw material. Its material is between gypsum board and stone, and can be cut, drilled and carved freely, so it is widely used in the construction field. In order to ensure the quality of the prefabricated cement board, it is usually necessary to test its compressive resistance and flexural resistance after the cement board is produced. [0003] During the compression test, the cement board is compressed until it breaks. However, the blocky plates produced during the breakage may shoot out and cause harm to the surrounding personnel, which has obvious shortcomings. Contents of the invention [0004] In order to reduce the possibility of the cement board sample hurting the...
