Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to a concrete slump test device. Background Art

[0002] Slump is a key indicator of concrete workability, often used on-site and in the laboratory to determine the fluidity of a mix, supplemented by intuitive empirical assessments of cohesion and water retention. It quantitatively measures the fluidity of concrete and is a crucial indicator for determining whether construction can proceed normally.

[0003] During the concrete slump test, when the slump cone is lifted up to demould, it is easy to deviate left and right due to instability during the lifting process, causing the slump cone to collide with the concrete, thereby affecting the final experimental test results and being inconvenient to use. At the same time, since unsolidified concrete is poured into the slump cone and solidified by natural air drying, it takes a long time to solidify, which reduces the solidification efficiency.

[0004] Therefore, we made improvements and proposed a concrete slump test device. Utility Model Content

[0005] The purpose of the utility model is to address the problem that the existing collapse cone collides with the concrete, thereby affecting the final experimental test results, is inconvenient to use, and solidifies naturally by air drying, which takes a long time to solidify and reduces the solidification efficiency.

The top of the support plate is provided with a separation component for separating the slump cone and the concrete, and the solidification component for rapid solidification of the concrete is provided above the separation component.

[0007] The separation assembly includes fixed plates fixedly connected on both sides of the top of the support plate, a telescopic cylinder fixedly connected to the outer side of the fixed plate, the telescopic end of the telescopic cylinder passes through the fixed plate and is fixedly connected to a connecting rod, one end of the connecting rod is fixedly connected to a connecting frame, one end of the connecting frame is hinged with a connecting plate, and one end of the connecting plate is fixedly connected to a collapse cylinder shell.

[0027] Example

[0028] Please refer to Figure 1 and Figure 2 A concrete slump test device comprises a support plate 1, a separation component 2, and a solidification component 3. The top of the support plate 1 is provided with a separation component 2 for separating the slump cone and the concrete. The solidification component 3 for rapid solidification of the concrete is provided above the separation component 2.

[0029] The separation assembly 2 includes a fixed plate 201 fixedly connected to both sides of the top of the support plate 1, a telescopic cylinder 202 fixedly connected to the outside of the fixed plate 201, the telescopic end of the telescopic cylinder 202 passes through the fixed plate 201 and is fixedly connected to a connecting rod 203, one end of the connecting rod 203 is fixedly connected to a connecting frame 204, one end of the connecting frame 204 is hinged with a connecting plate 205, one end of the connecting plate 205 is fixedly connected to a collapse cylinder shell 206, and the telescopic cylinder 202 is manually started, so that the telescopic end of the telescopic cylinder 202 drives the connecting rod 203 to move toward the middle of the fixed plate 201 The connecting rod 203 drives the connecting frame 204 to move toward the middle, and then the connecting rod 203 drives the connecting frame 204 to move synchronously, and then the connecting frame 204 drives the connecting plate 205, so that the connecting plate 205 starts to rotate the angle, and then the connecting plate 205 pushes the collapse cylinder shell 206 to move toward the middle of the support plate 1, so that the collapse cylinder shells 206 on both sides begin to combine together to form a collapse cylinder, and then manually pour the concrete that needs to be tested into the collapse cylinder. When the concrete solidifies, it can be demoulded by simply performing the above operation in reverse. It can be easily combined and demoulded for experiments and is convenient to use.

[0030] Further, such as Figure 2 As shown, the solidification component 3 includes a rotating plate 301 arranged above the collapse cylinder shell 206, and a driving motor 302 is fixed to the top of the rotating plate 301. The output end of the driving motor 302 passes through the bottom end of the fixed plate 201 and is fixedly connected to a rotating fan 303. When the concrete to be tested in the experiment is poured into the collapse cylinder, the driving motor 302 is started, so that the driving motor 302 starts to drive the rotating fan 303 to rotate inside the protective shell 5, and then the rotating fan 303 quickly dries and solidifies the concrete inside the collapse cylinder through wind force. At the same time, the knob rod 6 can also be rotated to make the knob rod 6 drive the rotating plate 301 to adjust the blowing angle of the rotating fan 303, which can quickly dry and solidify the concrete and improve the solidification efficiency.

[0031] The use process of the concrete slump test device provided by the utility model is as follows:

[0032] During use, the telescopic cylinder 202 is manually started, so that the telescopic end of the telescopic cylinder 202 drives the connecting rod 203 to move toward the middle of the fixed plate 201, so that the connecting rod 203 drives the connecting frame 204 to move toward the middle, and then the connecting rod 203 drives the connecting frame 204 to move synchronously, and then the connecting frame 204 drives the connecting plate 205, so that the connecting plate 205 starts to rotate the angle, and then the connecting plate 205 pushes the collapse shell 206 to move toward the middle of the support plate 1, so that the collapse shells 206 on both sides begin to combine together to form a collapse The concrete to be tested is poured into the slump cylinder manually. When the concrete solidifies, demoulding can be performed by simply performing the above-mentioned operation in reverse. When the concrete to be tested is poured into the slump cylinder, the drive motor 302 is started to drive the rotating fan 303 to rotate inside the protective shell 5. The rotating fan 303 then uses wind power to quickly dry and solidify the concrete inside the slump cylinder. At the same time, the knob rod 6 can also be rotated to drive the rotating plate 301 to adjust the blowing angle of the rotating fan 303.
