Description

Technical Field

[0001] The utility model relates to the technical field of concrete moulds, in particular to a concrete specimen forming mould. Background Art

[0002] In the experiment of determining the compressive strength of concrete, it is necessary to first form standard specimens of concrete. The concrete specimens used in the concrete compressive strength experiment are all formed by standard forming molds. After the concrete stones are formed by the forming molds, the concrete stones need to be cured for a period of time before their strength can be tested.

[0003] After searching the Chinese patent CN218398664U, a concrete specimen forming mold was found. This patent can clamp the air gun nozzle by setting an air gun nozzle slot, which is convenient for operation during inflation. A plug is provided at the air inlet to close the air inlet on the inner side of the bottom plate, and the air inlet is designed to be a conical structure with a large inside and a small outside to support the plug, thereby preventing slurry from leaking from the air inlet or blocking the air inlet, and preventing the test block from hanging on the air inlet.

[0004] However, the existing concrete specimen forming mold still has some shortcomings. For example, although the existing concrete specimen forming mold can support the plug through a cone-shaped structure with a large inside and a small outside, the effect of supporting the plug relying solely on the cone shape is not good. When pouring concrete into the mold and when pressurizing the concrete, the plug may move downward under the action of the gravity and pressure of the concrete, thereby causing the plug to separate from the air inlet and causing concrete leakage. Utility Model Content

[0005] In view of the problems in the related technology, the utility model proposes a concrete specimen forming mold to overcome the above technical problems existing in the existing related technology.

[0006] To this end, the specific technical solutions adopted by the utility model are as follows:

[0008] Furthermore, in order to seal the air inlet and prevent concrete from being discharged from the air inlet and causing concrete leakage, the sealing mechanism includes a plug arranged inside the air inlet, the plug matching the air inlet, one end of the plug connected to the mounting plate, a slot is provided at the top of the mounting plate, a block is provided below the slot, the block matches the slot, the block is connected to the threaded rod through a connecting block, a fixing frame is provided on one side of the air inlet, and one end of the threaded rod passes through the fixing frame and is connected to the limiting plate.

[0010] Furthermore, in order to ensure that the card block and the card slot can be correctly aligned and that the card block can be correctly placed inside the card slot, a first limit block is provided on one side of the turntable and a second limit block is provided on the bottom plate.

[0011] Furthermore, the clamping block is fixedly connected to the connecting block, and the connecting block is fixedly connected to the threaded rod.
