Description

Technical Field

[0001] The present application relates to the field of concrete technology, and in particular to a concrete test block compression mold. Background Art

[0002] Concrete is abbreviated as "concrete": it is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as the cementitious material, sand and stone as aggregates; mixed with water in a certain proportion and obtained by mixing, also called ordinary concrete, which is widely used in civil engineering.

[0003] The existing patent (Announcement No.: CN219788737U) discloses a concrete test block compression mold, which belongs to the field of concrete testing technology, including a support seat, a third baffle and a partition. The support seat is enclosed by a bottom plate, a first baffle and a second baffle to form a semi-enclosed support structure. The third baffle is provided with a U-shaped first groove. A U-shaped first strip protrusion is arranged on the support seat on the opposite side of the second baffle. The first groove and the first strip protrusion are matched in a concave-convex manner. The partition is arranged between the second baffle and the third baffle. The partition is provided with a U-shaped second groove. The support seat is provided with an L-shaped second strip protrusion. The third baffle is vertically provided with a third strip protrusion aligned with the second strip protrusion. The second groove is spliced ​​with the second strip protrusion and the third strip protrusion to form a U-shaped structure with a concave-convex fit. The concrete test block compression mold can produce multiple concrete test blocks at the same time. The rapid disassembly of the third baffle and the partition is conducive to the rapid demoulding of the concrete test blocks.

[0004] During the use of the above-mentioned document, its instruction manual states that the mixed concrete slurry is poured into the chamber. During the pouring process, a large number of bubbles will be mixed into the concrete slurry. When the concrete solidifies, the bubbles will cause cavities to exist in the concrete specimen, thereby affecting the rigidity of the concrete specimen. When taking out the concrete specimen, it needs to be disassembled and removed, which is inconvenient to use. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application provides a concrete test block compression mold, which has the advantages of being easy to remove the test piece and remove bubbles in the concrete, and solves the problems raised in the background technology.

[0006] To achieve the above object, the present application provides the following technical solution: A compression mold for concrete test blocks, including a body, inside which there is a mold body. On the bottom surface of the mold body, two vibration transmission members are installed. On the bottom surfaces of the two vibration transmission members, a plurality of convex blocks distributed in a circular pattern are fixedly connected. Inside the body, there are two swing frames. On the upper surfaces of the two swing frames, two sliding rods are slidably inserted. On the outer surfaces of the plurality of sliding rods, a plurality of strong springs are fixedly connected. The other ends of the plurality of strong springs are fixedly connected to the swing frames close to them. The upper ends of the plurality of sliding rods are in contact with the convex blocks close to them.

[0007] Through the above solution, by installing strong springs, the deformation force of the strong springs can be used to push the sliding rods to impact the vibration transmission members, so that the vibration is transmitted to the inside of the mold body through the vibration transmission members.

[0008] Furthermore, a plurality of rubber buffer columns distributed in a matrix are fixedly connected to the inner wall of the body, and the plurality of rubber buffer columns are all in contact with the mold body.

[0009] Through the above solution, installing the rubber buffer columns can enable the mold body to be in flexible contact with the body, thereby reducing the vibration transmitted to the body.

[0010] Furthermore, on the left and right sides of the body, first threaded rods are threadedly connected. On the ends of the two first threaded rods close to each other, first rubber plates are rotatably connected. The two first rubber plates are both in contact with the mold body.

[0011] Through the above solution, the cooperation of installing the first rubber plates and the first threaded rods can clamp the mold body, so that the mold body can be stably placed inside the body.

[0012] Furthermore, on the front and back of the body, second threaded rods are threadedly connected. On the upper ends of the two second threaded rods, clamping plates are rotatably connected. On the bottom surfaces of the two clamping plates, second rubber plates are fixedly connected. The two second rubber plates are both in contact with the mold body.

[0013] Through the above solution, installing the clamping plates and the second rubber plates can fix the mold body to prevent the mold body from jumping inside the body.

[0014] Furthermore, two support plates are installed on the inner wall of the body. On the upper surfaces of the two support plates, rotating rods are rotatably connected. On the upper ends of the two rotating rods, they are fixedly connected to the swing frames close to them. On the bottom ends of the two rotating rods, pulley wheels are fixedly connected. The two pulley wheels are connected by a belt in transmission. Inside the body, there is a motor, and the output end of the motor is fixedly connected to the bottom end of the rotating rod on the left side.

[0015] With the above solution, the cooperation between the installed pulley and the belt enables the two rotating rods to rotate synchronously, enabling stable transmission of power and enabling the rotating rods to drive the swing frame to rotate.

[0016] Furthermore, a plurality of bottom plates are provided below the device body, buffer members are fixedly connected to the upper surfaces of the plurality of bottom plates, a plurality of buffer grooves are formed in the bottom surface of the device body, the plurality of buffer members are all slidably connected to the sliding grooves close to them, buffer springs are fixedly connected to the upper surfaces of the plurality of buffer members, and the other ends of the plurality of buffer springs are all fixedly connected to the buffer grooves close to them.

[0017] With the above solution, the cooperation between the installed buffer springs, buffer grooves and buffer members can buffer the vibration generated during the operation of the device body, reduce the vibration transmitted to the bottom surface, and thus enable the device body to maintain stability.

[0018] Furthermore, the upper ends of the sliding rods are all spherical.

[0019] With the above solution, the upper ends of the sliding rods being spherical can facilitate the contact between the sliding rods and the convex blocks and avoid motion interference between the two.

[0020] Furthermore, the vibration transmission members are all in a horizontal state with the inner bottom wall of the mold body.

[0021] With the above solution, the vibration transmission members being in a horizontal state with the inner bottom wall of the mold body can avoid affecting the manufacture of concrete specimens and ensure the integrity of the concrete specimens.

[0022] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0023] For this concrete test block compression mold, by installing the cooperation of the strong springs, sliding rods and convex blocks, the vibration transmission members can be impacted to generate vibration, so that the vibration is transmitted to the mold body, and the air bubbles in the concrete of the mold body can be discharged under the influence of the vibration, avoiding their retention in the concrete. And when the concrete specimen is formed, the vibration transmitted through the vibration transmission members can separate the formed specimen from the mold body, facilitating the removal of the concrete specimen in the mold body.
