Description

Technical Field

[0001] The utility model relates to the technical field of concrete sample preparation, in particular to a self-compacting and easily disassembled concrete mold box. Background Art

[0002] Concrete strength is an important factor affecting the reliability of concrete structures. To ensure the reliability of structures, concrete production control and qualification assessment must be carried out. Concrete test blocks are divided into standard curing and same-condition curing according to the curing method. After the pouring of concrete for construction projects is completed, it is necessary to maintain the appropriate temperature and humidity required for the cement in the concrete to be fully hydrated for a certain period of time. The purpose is: first, to prevent abnormal shrinkage and cracking of concrete after molding due to natural factors such as exposure to the sun, wind, and dryness; second, to create conditions for the full hydration of cement and accelerated hardening of concrete.

[0003] During construction, the mixed concrete is poured into the specified cubic test mold, vibrated and formed, and cured at the specified temperature and humidity for 28 days before a pressure test strength test is carried out. The 150mm cubic specimen is used as the standard, and the 100mm and 200mm cubic specimens are converted according to the specified size conversion coefficient. The strength of the concrete itself can be directly understood through the test. During construction, the equivalent curing pressure test results of the specimens made under the same conditions under witness conditions can be used as the basis for re-inspection of the structural entity strength grade after conversion.

[0004] The concrete test block mold box is small in size and cannot be vibrated by existing vibrating equipment. It can only be vibrated manually. After the concrete is poured into the mold box, the template is hit with a steel nail or a wooden stick to discharge the air and moisture in the concrete, or a long stick or a vibrating rod is used to vibrate the concrete surface to make the concrete dense. Although this method can vibrate the concrete densely, it has a lot of randomness and large manual operation errors. Therefore, the inspection quality of the concrete test block is uneven and affects the test results. In addition, the traditional concrete mold box has only one open cube, and the concrete test block is difficult to disassemble after forming. Utility Model Content

[0005] The utility model aims to provide a self-compacting and easily disassembled concrete mold box, which solves the problem that the quality of concrete test blocks cannot be guaranteed and the concrete test blocks are difficult to disassemble due to the large randomness of the compaction degree of artificial vibration.

[0006] The utility model is realized by the following technical solutions:

[0007] A self-compacting and easily dismantled concrete formwork box, comprising a formwork box frame, a lateral compacting device, a bottom compacting device and a control system;

[0008] The mold box frame includes a square shell and a grid-shaped frame, the top of the square shell is an open end, the square shell is arranged on the bottom compacting device, the grid-shaped frame is arranged on the top of the square shell, the grid-shaped frame includes two parallel long sides, and at least one short side is vertically arranged on the two long sides; the short side is located between the two long sides and extends downward to form a vertical plate, the bottom of the vertical plate is connected to the bottom of the square shell; the two long sides and the two side walls of the square shell each form a demolding groove;

[0009] The lateral compacting device comprises two lateral compacting mechanisms, which are respectively slidably arranged in two demolding grooves. When the two lateral compacting mechanisms slide to be sealed and connected with both sides of the vertical plate, a square slot hole for containing concrete is formed between the two lateral compacting mechanisms, the vertical plate and the square shell;

[0010] A bottom plate vibrator is provided in the bottom compacting device;

[0011] A lateral vibrator is provided in the lateral compactor;

[0012] The control system is used to drive the bottom plate vibrator and the lateral vibrator to vibrate.

[0013] The bottom plate vibrator and the lateral vibrator described in the utility model are both prior art, and driving the bottom plate vibrator and the lateral vibrator to vibrate by controlling the controller is also prior art.

[0014] The utility model is provided with a bottom plate vibrator in a bottom compacting device and a lateral vibrator in a lateral compacting machine, so that the bottom and two side walls of concrete poured in a square slot can be vibrated respectively to achieve vibration.

[0015] The square slot hole described in the utility model is not a fixed structure, but when the two lateral compacting mechanisms slide to be sealed and connected with the two sides of the vertical plate, a square slot hole for containing concrete is formed between the two lateral compacting mechanisms, the vertical plate and the square shell. When the concrete curing is completed and the formwork needs to be removed, the lateral compacting mechanisms are directly slid away from the concrete to expose the two side walls of the concrete. Together with the bottom, the concrete piece has three sides exposed, which is convenient for taking out the concrete piece.

[0016] In summary, the utility model can not only solve the problem that the quality of concrete test blocks cannot be guaranteed due to the large randomness of the density of artificial vibration, but also the problem that the concrete test blocks are difficult to disassemble.

[0017] Further, the lateral compacting mechanism includes a lateral cover plate, a lateral base and a lateral vibrator;

[0018] The lateral cover plate and the lateral base are detachably connected;

[0019] The lateral base is recessed toward one end away from the lateral cover plate to form a lateral slot; the number of the lateral slots corresponds to the square slot holes one by one;

[0020] The lateral vibrators are arranged in the lateral slots in a one-to-one correspondence.

[0021] Furthermore, the lateral slot is a square slot, the lateral vibrator is a circular structure, and rubber is filled between the lateral vibrator and the square slot.

[0022] Furthermore, the tops of the lateral cover plates and the lateral bases are both provided with side plate sliding grooves matching the short sides.

[0023] Furthermore, a handle is provided on the lateral cover plate, and a through slot for passing the handle is provided on the side wall of the square shell.

[0024] Further, the bottom compacting device includes a bottom plate cover, a bottom plate vibrator and a bottom plate base;

[0025] The bottom plate cover and the bottom plate base are detachably connected;

[0029] Furthermore, a slide groove is provided at the bottom of the demolding groove, and the bottom of the lateral compacting mechanism can slide in the slide groove along the length direction of the short side.

[0030] Further, the control system includes a detachably connected placement box and a box cover;

[0031] The placement box is provided with a power supply and a controller;

[0032] The box cover is provided with a gear shifting button and a gear position indicator; the controller is electrically connected with the gear shifting button, the bottom plate vibrator and the lateral vibrator.

[0033] Furthermore, the control system, the mold box frame and the lateral compacting device are all installed on the upper end surface of the bottom compacting device.

[0035] 1. The utility model is provided with lateral compacting devices and bottom compacting devices on two sides to vibrate the concrete. The concrete can be compacted from three sides by vibration. Compared with the test block of manually vibrated concrete, the quality is more guaranteed. Compared with the traditional vibration plate, the self-compacting and detachable concrete mold box is more convenient and simple to operate. It has its own power supply and can be vibrated randomly, which avoids the storage time of uniformly vibrated concrete being too long, affecting the test block detection effect.

[0036] 2. The utility model can pull the lateral compacting mechanism by the handle to expose three sides of the concrete test block, making the removal of the concrete more convenient and quick, avoiding the difficulty of removing the traditional concrete mold box and the need to apply a demolding agent, thereby greatly improving work efficiency.
