Description

Technical Field

[0001] This utility model relates to the field of concrete test block preparation technology, specifically a bamboo structure box. Background Technology

[0002] Concrete requires sampling tests during use, and concrete test blocks are products prepared during these tests to assess concrete performance. When preparing test blocks, molds are necessary to obtain the shaped concrete blocks. The shaped concrete blocks need to undergo demolding to obtain standard concrete test blocks. The quality of demolding has a significant impact on the quality of the test blocks.

[0003] Existing concrete specimen demolding devices and methods mainly rely on manual demolding and impact demolding. Manual demolding can easily cause significant damage to both the specimen and the mold. Impact demolding mainly uses pneumatic and hydraulic impact to separate the specimen from the mold. In existing technologies, the gun head and the mold are magnetically connected using magnetic materials or fixed using plastic materials. When magnetically connected, the strength of the magnetic force is affected by the material of the concrete specimen. If the material or surface characteristics of the specimen change, the firmness of the magnetic connection may decrease. Plastic materials, due to their poor structural strength, cause the mold box to be discarded after a preset number of uses. This not only affects the environment because plastic cannot be effectively degraded, failing to meet environmental protection requirements, but also increases the cost of use due to the limited number of uses, affecting the user experience. Utility Model Content

The bottom of the mold shell is provided with a mold base plate, and an impact hole penetrating through the center of the mold base plate is provided. Both the mold shell and the mold attachment device are bamboo products. The mold attachment device is fixedly connected to the middle of the outer side of the mold base plate. The mold attachment device has a connection hole corresponding to the impact hole. The connection hole can be sealed to an external air pressure gun head. The external air pressure gun head is rotated and fixed to the impact hole of the mold base plate through the connection hole.

[0005] Preferably, a circular connecting groove corresponding to the mold auxiliary device is provided in the middle of the outer side of the mold base plate, and a ventilation connecting groove is provided in the middle of the circular connecting groove, and the impact hole is provided in the middle of the ventilation connecting groove.

[0006] Preferably, the bottom outer side of the impact hole is provided with an annular protrusion that can abut against an external air pressure gun head.

[0007] Preferably, the mold attachment device has a second ventilation connection groove at the center of the side connected to the circular connection groove, which corresponds to the first ventilation connection groove. The second ventilation connection groove and the first ventilation connection groove form a gas gun head connection and fixing groove.

[0008] Preferably, the second ventilation connection groove and the connection hole form a symmetrical connection plate, and the connection plate abuts and fixes the external air pressure gun head to the air pressure gun head connection and fixing groove.

[0009] Preferably, the mold attachment is fixedly connected to the circular connecting groove via a colloid.

[0010] Preferably, both the mold shell and the mold attachment are made of bamboo veneer composite pressing.

[0011] Preferably, both the mold shell and the mold attachment are formed by pressing bamboo strips.

[0012] Preferably, the mold housing is provided with symmetrical handles on both sides of the top.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-8 The illustration shows a bamboo structure box, including a mold shell 1 and a mold attachment device 2. The bottom of the mold shell 1 is provided with a mold base plate 11, and an impact hole 12 penetrating through the mold base plate 11 is opened at the center of the mold base plate 11. Both the mold shell 1 and the mold attachment device 2 are bamboo products. The mold shell 1 and the mold attachment device 2 can be formed by pressing bamboo veneer composite. By stacking and pressing the bamboo veneer composite to form a hard and dense board, it is ensured that the mold shell 1 and the mold attachment device 2 can be naturally degraded after being discarded, effectively protecting the environment and hygiene. It can also ensure the firmness and stability of the device by improving the structural strength of the board.

[0026] In addition, the mold shell 1 and the mold attachment 2 can be formed by pressing bamboo strips. By using various types of bamboo for pressing, the utilization efficiency of bamboo can be effectively improved, and the production cost can be effectively reduced.

[0027] Please see Figure 1 and Figure 2 The mold attachment 2 is fixedly connected to the middle of the outer side of the mold base plate 11. The mold attachment 2 has a connection hole 21 corresponding to the impact hole 12. The connection hole 21 can be sealed to the external air pressure gun head. The external air pressure gun head completes the demolding of the concrete test block inside the mold shell through the impact hole 12.

[0028] Please see Figure 1-8 A circular connecting groove 13 corresponding to the mold attachment 2 is provided in the middle of the outer side of the mold base plate 11. The mold attachment 2 can be fixedly connected to the circular connecting groove 13 through the colloid.

[0029] A ventilation connection groove 14 is provided in the middle of the circular connection groove 13. The impact hole 12 is provided in the middle of the ventilation connection groove 14. An annular protrusion 15 is provided on the outer side of the bottom of the impact hole 12, which can abut against the external air pressure gun head. When the external air pressure gun head is connected to the impact hole 12, the rubber ring of the external air pressure gun head abuts against the annular protrusion 15 to form a sealed environment, thus completing the smooth demolding of the concrete test block.

[0030] The mold attachment 2 is connected to the circular connecting groove 13. At the center of the side, there is a second ventilation connecting groove 22, which corresponds to the first ventilation connecting groove 14. The second ventilation connecting groove 22 and the first ventilation connecting groove 14 form a pneumatic gun head connecting and fixing groove 3. The second ventilation connecting groove 22 and the connecting hole 21 form a symmetrical connecting plate 23. The connecting plate 23 abuts and fixes the external pneumatic gun head to the pneumatic gun head connecting and fixing groove 3. During operation, the external pneumatic gun head enters the pneumatic gun head connecting and fixing groove 3 through the connecting hole 21. After rotating, the external pneumatic gun head abuts and fixes to the pneumatic gun head connecting and fixing groove 3 through the connecting plate 23.

[0031] Please see Figure 1-3 The top of both sides of the mold housing 1 are symmetrically provided with handles 16, which allow users to lift the device, thus facilitating its transport and preventing it from falling during transport, ensuring the safety of the test block.

[0032] Please see Figure 1-8 When using this demolding device for demolding, first ensure that the mold attachment 2 has formed a firm and stable connection with the circular connecting groove 13 through the colloid. Then, insert the external air pressure gun head through the connecting hole 21 into the air pressure gun head connecting and fixing groove 3 formed by the second air connection groove 22 and the first air connection groove 14. Next, rotate the external air pressure gun head, and use the connecting plate 23 to abut the rubber ring of the external air pressure gun head against the annular protrusion 15, and connect the air outlet of the external air pressure gun head with the impact hole 12. The external air pressure gun head will then smoothly demold the concrete test block inside the mold shell 1 through the impact hole 12.
