For axial compressive strength test and static compressive elastic modulus test, 150*150*300mm prisms are used as standard test blocks.

[0003] The prior art discloses a concrete compression test device, comprising a lower pressure plate, a push plate slidably mounted on the four sides of the lower pressure plate to push a concrete test block, a sliding seat slidably mounted on the lower pressure plate and corresponding to the number of the push plates, a transmission rod rotatably mounted on the lower pressure plate and with a rotation axis perpendicular to the sliding direction of the sliding seat, a driving assembly mounted on the lower pressure plate and used to drive multiple sliding seats to move toward or away from one side of the push plate, and a linkage assembly mounted on the transmission rod and used to drive the sliding seats to slide synchronously. The side of the push plate away from the concrete test block is connected to the sliding seat, the driving motor can drive the transmission rod to rotate, the transmission rod drives the bevel gear to rotate, and then drives the adjacent transmission rods to rotate, so that the sliding seats move synchronously.

Specifically, the main body mechanism 100 includes a base 101, a bracket 102 is provided at the upper end of the base 101, a hydraulic press 103 is provided on the bracket 102, a pressing plate 104 is provided at the lower end of the hydraulic press 103, and the hydraulic press 103 can drive the pressing plate 104 to move up and down by telescopic movement, and the pressing plate 104 is the contact part with the concrete standard test block, and the centering mechanism 200 is installed on the bracket 102, and the centering mechanism 200 includes a pressure platform 201, which is a platform for placing the concrete standard test block, and a centering component is provided on the pressure platform 201, and the centering component includes a motor 202, and a rotating drum 203 is provided on the motor 202 and the pressure platform 201. The cylinder 203 is connected by a belt 204, and fixed blocks 207 are symmetrically installed at both ends of the belt 204. After the motor 202 is started, the belt 204 is driven to rotate, and the belt 204 drives the two fixed blocks 207 to move toward each other. A slider 206 is installed on the fixed block 207. Driven by the fixed block 207, the slider 206 can slide on the slide rail 205, and the slide rail 205 is fixed on the pressure platform 201. A centering block 208 is fixedly installed on the slider 206. Finally, the centering block 208 on the slider 206 moves. A centering component is which has two symmetrically installed centering blocks 208, and the two rely on the belt 204 to achieve equidistant movement toward each other. The centering component is provided with two groups, each group works independently, and the two are perpendicular to each other in position. After the concrete test block is placed on the upper end of the pressure platform 201, one group of centering components is started to center the test block in its direction, and then another group of centering components perpendicular to it is started to center it in another direction in the same way.

[0027] By setting up a centering component, the centering effect of the device on the concrete standard test block is achieved. Compared with the existing four-way linkage synchronous pushing method of the concrete test block centering, during the process of the two centering blocks 208 pushing the concrete test block, the test block has a free end and can rotate, thereby preventing the concrete test block from being between the centering blocks 208.

[0028] Second embodiment:

[0029] like Figure 2 As shown, a protective window 105 is hinged on the bracket 102, and a magnetic material is provided on the outer edge of the protective window 105. The bracket 102 is made of iron metal material.

[0030] After the concrete test block is subjected to the extreme pressure, the surface will crack, and the stress in some places will be large, which will cause concrete debris to splash out and easily injure people. By setting the protective window 105, the concrete debris can be prevented from splashing out of the device to protect the personal safety of the staff. The magnetic protective window 105 can be adsorbed on the bracket 102, and it is convenient to open and close.

[0031] Third embodiment:

After the test, it is also convenient to clean the concrete test block in the device.

[0033] Fourth embodiment:

[0034] like Figure 3 As shown, the pressure platform 201 is provided with a hole, and a cover plate 209 is provided at the upper end of the hole. The cover plate 209 and the pressure platform 201 are connected in a socket-type manner. During the test, the cover plate 209 is placed on the hole. After the test, the crushed concrete test block is first removed, and then the cover plate 209 is removed. Concrete debris on the pressure platform 201 can leak through the hole. The base 101 is an internal cavity structure. An opening is provided at the upper end of the base 101 corresponding to the hole on the pressure platform 201, and an opening is also provided on the side wall of the base 101. A recycling bag is placed in advance in the base 101, and the debris falls from the hole on the pressure platform 201 into the recycling bag in the base 101.

[0035] By providing holes on the pressure platform 201, it is convenient to recycle the broken concrete test blocks after the test, and the difficulty of cleaning the device by the staff is reduced.

[0036] Fifth embodiment:

[0037] like Figure 2 As shown, a panel 106 is provided at the upper opening of the base 101 , and the upper opening of the panel 106 is larger than the lower opening. The crushed concrete standard test block enters the interior of the base 101 through the hole in the pressure platform 201 and the hole in the upper end of the base 101 .

[0038] The enclosure 106 can reduce the probability of concrete test block debris falling outside the device, thereby ensuring the cleanliness of the experimental site.

[0039] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model.
