Detailed Description

The invention will be further described with reference to the following description and embodiments in conjunction with the accompanying drawings:

example 1

A self-compacting concrete performance testing device is shown in figure 1 and comprises a base plate 10, guide columns 11 are arranged on two sides of the base plate 10, and the tops of the two guide columns 11 are integrally connected together through a guide cross beam. The two guide posts 11 and the guide beam arranged between the two guide posts 11 form a guide frame, a round hole 111 extending along the height direction of the guide post 11 is arranged in the middle of the guide post 11, and the round hole 111 is provided with an opening on the upper surface of the guide post 11.

The middle of two guide posts 11 is provided with the support on the base plate 10, is provided with test box 20 on the support, and the centre of support is provided with support column 21, and the bottom mounting of support column 21 is on base plate 10, and the upper end of support column 21 upwards extends in the bottom plate of extending through test box 20 and stretching into test box 20, and the top that support column 21 stretched into in test box 20 is provided with horizontal brace table 22.

A test cartridge 30 is mounted on the support platform 22, the test cartridge 30 having an upwardly facing opening, and self-compacting concrete is mounted in the test cartridge 30 for testing.

The middle part top of direction crossbeam is provided with fastening block 12, the lift post 41 is worn to be equipped with in the central authorities of fastening block 12, the bottom of lift post 41 passes behind the direction crossbeam downwards and stretches into test box 20 in, lift post 41 can freely go up and down in fastening block 12 and the direction crossbeam, the bottom that lift post 41 stretched into in test box 20 is connected with test clamp plate 42, test clamp plate 42 is the same with the internal diameter of test section of thick bamboo 30 opening, test clamp plate 42 just in time is located the open-ended top of test section of thick bamboo 30.

The part of the lifting column 41 extending out of the upper part of the fastening block 12 is fixed with a balance weight testing block 43, a plurality of horizontal semi-arc grooves are formed in the side surface of the balance weight testing block 43, a balance rod 45 is arranged on each horizontal semi-arc groove in a penetrating mode, each balance rod 45 comprises a horizontal cross rod 451 and vertical rods 452 located at two ends of each cross rod and extending downwards, and the two vertical rods 452 are inserted into the round holes 111 of the guide columns 11 respectively.
