Description

A detachable concrete test mold

technical field

The utility model belongs to a detachable concrete test mold.

Background technique

When conducting some concrete performance research, concrete specimens of special thickness are required. For example, due to the influence of the adjustable height of the test bench, when using a high-power microscope to measure the hydration reaction of concrete specimens during the demoulding period, the height of the specimens cannot be adjusted. greater than 6cm; when using the hydrometer method to measure the concrete porosity, in order to facilitate full saturation in a short period of time, the concrete thickness should not exceed 3cm; and the concrete molds sold on the market are often only standard molds, so when doing some of the above tests, the previous solutions The method is, first, to make special or cut common molds, so that the cost is much higher than the actual value, and the used ones cannot be used for other tests, that is, the waste of economy will also affect the test process; second, pouring in standard test pieces Good concrete specimens, after the curing period, cut the concrete specimens with a cutting machine according to the test needs, but the flatness cannot be guaranteed when the cutting is too thin, and the cutting process may also cause damage to the concrete surface, affecting the accuracy of the test In addition, the general mold will be coated with a release agent before pouring to facilitate demoulding. There is a hole at the bottom of the mold, and an adhesive tape is placed before the test, so that the concrete will not block the hole. When demoulding, knock the shell repeatedly To ensure that the mold and the test piece are not connected, you can use the pump to demould from the bottom hole, but when the mold has been damaged, this method will not work because of air leakage, and it can only damage the mold; in addition, after the concrete is poured, you need to Vibrate the concrete sample with a micro vibrator, the concrete is easy to solidify on the vibrator, and it is troublesome to clean up. It is also troublesome to clean the concrete solidification mud solidified on the mold after the concrete specimen is demoulded.

Contents of the invention

The technical problem to be solved by the utility model is to provide a detachable concrete test mold, which can not only adjust the height of the concrete, but also facilitate the separation of the mold from the concrete.

In order to solve the above problems, the utility model adopts the following technical scheme: a detachable concrete test mold, including a square frame structure surrounded by four side plates, and a corner plate can be used between two adjacent side plates. Detachable connection, a bottom plate is inserted in the box structure, a sealing ring is provided between the bottom plate and the side plate, and a horizontal support rib and a longitudinal support rib are fixed on the end surface of the side plate, and one end of the longitudinal support rib is exposed from the side plate .

The pipe sleeve used to insert the vibrating rod is connected in the middle of the side plate. The pipe sleeve includes a joint, a rubber tube and a vibrating sleeve. One end of the joint is inserted into the side plate, and the other end of the joint is connected to the vibrating sleeve through the rubber tube.

The angle plate and the side plate are connected through the detachable bolt, and a sealing strip is arranged between the angle plate and the side plate.

The upper end of the angle plate is flush with the upper end of the side plate, and the lower end of the angle is located in the frame structure. A sealing block is fixed at the lower end of the angle plate. After the bottom plate is inserted into the frame structure, the sealing block is pressed against the end surface of the bottom plate.

Four corners of the bottom plate are respectively provided with a fixed column, and a screw rod for adjusting the height is screwed on the lower end surface of the fixed column.

The beneficial effects of the utility model are: during the test, pour the concrete into the test mold spliced by the side plate, the angle plate and the bottom plate. One end of the rib is exposed to the concrete. After separating the side panels from the concrete, the corner panels and the bottom panels can be separated. The separated side panels, corner panels and bottom panels can be used again. Hesitation is to dismantle them in sections, so the removed side panels and bottom panels do not need to be removed. It will be broken; when vibrating concrete, the vibrating rod can be inserted into the vibrating sleeve from the joint to vibrate the concrete, thus avoiding the concrete from solidifying on the vibrating rod; when separating the side plate, the vibrating sleeve can be left In the concrete sample, the vibrating sleeve and the joint are separated from the rubber sleeve; the screws at the four corners of the bottom plate can easily adjust the frame structure and the height of the bottom plate to facilitate the leveling of the concrete sample.

detailed description

As shown in Figures 1 to 5: a detachable concrete test mold, including a square frame structure surrounded by four side panels 1, and a corner panel 2 is detachable between two adjacent side panels 1 connection, a bottom plate 4 is inserted in the frame structure, a sealing ring is provided between the bottom plate 4 and the side plate 1, and a horizontal support rib 3 and a longitudinal support rib 31 are fixed on the end surface of the side plate 1, and the longitudinal support rib 31 One end of the side plate 1 is exposed, and the longitudinal support rib 31, the transverse support rib 3 and the side plate 1 are integrally injection molded.

After the concrete is solidified in the test mold spliced by the side plate 1, the corner plate 2 and the bottom plate 4, first remove the connecting piece between the side plate 1 and the corner plate 2, and then use a hammer to strike the longitudinal support rib outward 31 exposes one end of the concrete, so that the side plate 1 can be separated from the concrete specimen; the support rib can increase the strength of the side plate 1, and when the longitudinal support rib 31 is struck, the side plate 1 is stressed as a whole to avoid hitting the support rib The side panel 1 was partially broken during boarding.

The sleeve connected to the middle of the side plate 1 is used to insert the vibrator. The sleeve includes a joint 52, a rubber tube 53 and a vibration sleeve 51. One end of the joint 52 is inserted into the side plate 1, and the other end of the joint 52 passes through the rubber tube. The pipe 53 is connected with the vibrating sleeve 51 . When the side plate 1 is separated, the vibrating sleeve 51 remains in the concrete, and the joint 52 is separated from the vibrating sleeve 51 at the rubber tube 53;

The angle plate 2 and the side plate 1 are detachably connected by bolts 6 , and a sealing strip 22 is provided between the angle plate 2 and the side plate 1 . When moulding, the bolt 6 can be used to compress the sealing strip 22 between the side plate 1 and the corner plate 2 to improve the sealing effect and prevent water from flowing out from the gap between the side plate 1 and the corner plate 2.

The upper end of the corner plate 2 is flush with the upper end of the side plate 1, and the lower end of the angle is located in the frame structure. A sealing block 21 is fixed at the lower end of the corner plate 2. After the bottom plate 4 is inserted into the frame structure, the sealing block 21 is pressed against the frame structure. On the end face of the bottom plate 4. The sealing block 21 is made of rubber. After the base plate 4 is inserted into the frame structure, press down on the frame structure so that the sealing block 21 is pressed against the base plate 4 to prevent water from flowing between the base plate 4 and the corner plate 2. The gaps flow out; in addition, when doing the concrete porosity test, the thickness of the concrete is required to be below 3cm. At this time, the corner plate 2 with a length of less than 3cm can be replaced to ensure that the concrete thickness is less than 3cm.

Four corners of the bottom plate 4 are respectively provided with a fixed post 41 , and a screw rod 42 for adjusting height is threadedly connected to the lower end surface of the fixed post 41 . The screw rods 42 at the four corners of the base plate 4 can easily adjust the height of the frame structure and the base plate 4 to facilitate the leveling of the concrete sample.
