Description

Technical Field

[0001] The utility model relates to the field of demoulding of concrete durability test anti-seepage test molds, in particular to a demoulding device for concrete anti-seepage test molds. Background Art

[0002] Concrete impermeability refers to the material's ability to resist penetration under the action of water, oil and other pressures. During the concrete durability test, the concrete impermeability test piece usually needs to be tied with rubber bands and wrapped with melted paraffin to ensure the sealing between the test piece and the test mold. After the test, the concrete impermeability test piece needs to be separated from the test mold of the impermeability test detection device. The traditional method is time-consuming, labor-intensive and relatively dangerous. At present, there is no special auxiliary tool on the market that can save time, effort and safely remove the impermeability test piece. Utility Model Content

[0003] The utility model aims to provide a convenient demoulding device for a concrete impermeability test mold, which can safely and efficiently remove an impermeability test piece from the test mold.

[0004] In order to achieve the above purpose, a demoulding device for concrete impermeability test mold is designed, comprising:

[0005] An upper deck, wherein a plurality of connecting guide pillars are provided on the periphery of the bottom of the upper deck, and each of the guide pillars is provided with a groove with a bottom opening;

[0006] A lower bearing plate, wherein a plurality of connecting columns are provided on the circumferential side of the top of the lower bearing plate, wherein the connecting columns are matched and connected with the grooves of the connecting guide columns of the upper bearing plate, and the ends of the connecting columns are connected with the connecting guide column grooves through elastic bodies;

[0007] A support plate is arranged between the upper support plate and the lower support plate, wherein a through hole is arranged in the middle of the support plate, and two ends of the support plate pass through the connecting pillars of the lower support plate and are matched and connected with the connecting guide pillars of the upper support plate;

[0008] A top block arranged in the middle of the lower bearing plate;

[0009] A clamp is arranged on the upper bearing plate connecting guide pillars.

[0010] The top block and the through hole of the supporting plate form an avoidance.

[0011] The clamp is mounted on the connecting guide column of the upper bearing plate through a clamping sleeve, and an arc-shaped clamp is arranged on the inner side of the clamping sleeve for limiting the outer wall of the concrete anti-seepage test mold.

[0012] The utility model has the advantages of simple and novel structural design, high efficiency and safety in application and operation. The device can be directly placed on a universal material testing machine, and the universal material testing machine can be started. By compressing the upper and lower bearing plates to displace the spring support rod, the top block rises and can push the test block in the impermeability test mold between the supporting plate and the clamp to between the clamp and the upper bearing plate, so that the test block is separated from the impermeability test mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 This is the specific structural diagram of a demoulding device for a concrete anti-seepage test mold of the utility model;

[0014] In the figure: 1-upper bearing plate, 2-clamp, 3-connecting guide column, 4-support plate, 5-top block, 6-lower bearing plate; 7-connecting column. DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with the accompanying drawings. The structure and principle of the utility model are very clear to people in the field. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0016] like Figure 1 As shown, the utility model designs a demoulding device for concrete anti-seepage test mold, including

[0017] An upper deck 1, wherein a plurality of connecting guide pillars 3 are provided around the bottom of the upper deck, and each of the guide pillars is provided with a groove with a bottom opening;

[0018] A lower bearing plate 6, wherein a plurality of connecting columns 7 are provided on the circumferential side of the top of the lower bearing plate, wherein the connecting columns 7 are matched and connected with the grooves of the connecting guide columns 3 of the upper bearing plate 1, and the ends of the connecting columns 7 are connected with the grooves of the connecting guide columns 3 through elastic bodies;

[0019] A support plate 4 is arranged between the upper support plate 1 and the lower support plate 6. A through hole is provided in the middle of the support plate 4. Both ends of the support plate 4 pass through the connecting pillars of the lower support plate and are matched and connected with the connecting guide pillars 3 of the upper support plate 1.

[0020] It also includes a top block 5 arranged in the middle of the lower support plate 6, and a clamp 2 arranged on the upper support plate 1 connecting the guide column. The top block 5 and the through hole of the support plate 4 form an avoidance.

[0021] The clamp 2 is mounted on the connecting guide column 3 of the upper bearing plate 1 through a clamping sleeve, and an arc-shaped clamp is arranged on the inner side of the clamping sleeve for limiting the outer wall of the concrete anti-seepage test mold.

[0022] In this embodiment, a concrete test mold with a movable bottom plate is used. The bottom of the test mold is provided with a through hole that will not collide with the top block 5 of the present application. The bottom plate made of a thin steel plate is movably and detachably installed at the bottom of the test mold.

[0023] The Figure 1 Place the device on the universal material testing machine and align it in the center. Place the concrete impermeability test mold to be demoulded in the center. Figure 1 On the middle support plate 4, the clamp 2 is tightly fitted with the outer edge of the test mold, the top surface of the upper support plate 1 of the present application device is against the upper pressure surface of the universal material testing machine, and the bottom surface of the lower support plate 6 of the present application device is against the top of the telescopic cylinder of the universal material testing machine. The universal material testing machine is started, and the cylinder of the universal material testing machine is lifted, so that the upper support plate 1 and the lower support plate 6 are close to each other, the elastic material in the groove of the connecting guide column 3 is compressed, and the groove gap between the connecting guide column 3 and the connecting column 7 is gradually reduced, and the top block 5 moves upward. At this time, the concrete impermeability test piece located between the support plate 4 and the clamp 2 is pushed away from the impermeability mold by the top block 5.

[0024] The utility model has a simple structure and can demould the anti-permeability test piece through the existing universal material testing machine in the construction site laboratory without adding other lifting systems. The universal material testing machine has a stable displacement rate, strong controllability, safety and environmental protection.
