Description

Technical Field

[0001] The utility model belongs to the technical field of casting moulds, and more specifically relates to a concrete test block casting mould. Background Art

[0002] When conducting a concrete freeze-thaw experiment, it is necessary to cast a concrete test block in a long strip casting mold. Since a probe needs to be set in the concrete test block, before casting the concrete test block, it is necessary to open a hole on one of the end walls in the length direction of the casting mold, and then insert the probe into the casting mold through the opened hole, and one section of the electrical connection line connected to the probe is inserted into the mold with the probe, and the other section remains outside the mold. After the casting is completed, the probe is fixed in the concrete test block. Since an electrical connection line is inserted into the end wall of the casting mold, the concrete test block cannot be directly taken out of the casting mold. Only by destroying the end wall of the casting mold for inserting the electrical connection line can the concrete test block be taken out of the casting mold. This results in each casting mold only being able to cast one concrete test block, and it cannot be reused, which is relatively wasteful. Utility Model Content

[0027] Please also read Figure 1 and Figure 2The concrete test block casting mold provided by the utility model is now described. The concrete test block casting mold comprises a mold body 1, the opening of the mold body 1 faces upward, one of the end walls in the length direction of the mold body 1 is a first end wall 11, the first end wall 11 is provided with a through hole 12, the first end wall 11 is divided into a fixed part 111 and a disassembly part 112, the fixed part 111 and the disassembly part 112 are evenly divided into the through hole 12, the fixed part 111 is fixed on the bottom wall of the mold body 1, and the disassembly part 112 is detachably connected to the fixed part 111.

[0028] Compared with the prior art, the concrete test block casting mold provided by the utility model is a mold that inserts the probe into the mold body 1 through the penetration hole 12, and one section of the electrical connection line electrically connected to the probe is inserted into the mold along with the probe, and the other section is left outside the mold. After the casting is completed, the connection between the disassembly part 112 and the fixing part 111 is disconnected, thereby opening the penetration hole 12, so that when the concrete test block is taken out of the mold body 1, the first end wall 11 will not hinder the electrical connection line. After the disassembly part 112 is reconnected with the fixing part 111, the mold body 1 can be reused, so it can avoid the problem that after the concrete test block is cast, the end wall of the casting mold for passing the electrical connection line needs to be destroyed before the concrete test block can be taken out of the casting mold, resulting in the problem that the casting mold cannot be reused.

[0029] In some embodiments, the above-mentioned characteristic mold body 1 can be used as follows Figure 1 See the structure shown. Figure 1 The upper end of the mold body 1 has a first outward folded edge 13. The first folded edge 13 can increase the strength of the mold body 1, and the mold body 1 can also be moved through the first folded edge 13.

[0030] In some embodiments, see Figure 2 and Figure 3, the disassembly portion 112 is slidably inserted into the fixed portion 111 along the vertical direction, the first folding edge 13 has a first connecting portion 131 located on the fixed portion 111 and a second connecting portion 132 located on the disassembly portion 112, and the concrete test block casting mold also includes a locking assembly, and the locking assembly includes a limit plate 2 and a limit shaft 3. The limit plate 2 is fitted on the first folding edge 13, and the limit plate 2 is rotatably connected to the first connecting portion 131 around a vertical axis so that the limit plate 2 can fit with the second connecting portion 132 or avoid the space above the fixed portion 111. The limit shaft 3 is vertically arranged, and when the limit plate 2 fits with the second connecting portion 132, the limit shaft 3 is used to slide through the limit plate 2 and the second connecting portion 132. At this time, the limiting plate 2 can limit the upward movement of the disassembly part 112 through the second connection part 132, and at the same time, the limiting shaft 3 can limit the horizontal movement of the disassembly part 112, so that the disassembly part 112 is fixedly connected with the fixing part 111. After the limiting shaft 3 slides out of the second connection part 132, the limiting plate 2 rotates to avoid the space above the second connection part 132, and the disassembly part 112 can slide upward to disengage from the fixing part 111, thereby disconnecting the disassembly part 112 from the fixing part 111.

[0031] In some embodiments, the feature locking component can be used as follows: Figure 3 See the structure shown. Figure 3 The locking assembly further includes a limiting tube 4 and a fixing ring 5. The limiting tube 4 is fixed on the limiting plate 2 and coaxially sleeved outside the limiting shaft 3. The fixing ring 5 is slidably sleeved outside the limiting shaft 3 and fixed on the limiting tube 4. The side wall of the limiting shaft 3 has a protruding portion 31 protruding outward, and the protruding portion 31 is located in the limiting tube 4. The limiting plate 2 and the fixing ring 5 limit the protruding portion 31, so that the protruding portion 31 can only move in the limiting tube 4, thereby preventing the limiting shaft 3 from being lost.

[0032] In some embodiments, the feature locking component can be used as follows: Figure 3 See the structure shown. Figure 3 The locking assembly further includes a compression spring 6. The compression spring 6 is located in the limiting tube 4 and sleeved on the limiting shaft 3. The two ends of the compression spring 6 are respectively in contact with the protrusion 31 and the fixing ring 5. The resilience of the compression spring 6 can increase the resistance of the limiting shaft 3 sliding out of the second connecting portion 132, thereby increasing the stability of the state of the limiting shaft 3 after it penetrates into the second connecting portion 132.

[0033] In some embodiments, the above-mentioned characteristic limiting axis 3 can be adopted as follows Figure 3 See the structure shown. Figure 3 The side wall of the limiting shaft 3 has a hand-kneading portion 32 protruding outward, and the hand-kneading portion 32 is located above the fixing ring 5. The operator can drive the limiting shaft 3 to slide by pinching the hand-kneading portion 32 with his hand.

[0034] In some embodiments, the feature locking component can be used as follows: Figure 3 See the structure shown. Figure 3 The locking assembly also includes a connecting shaft 7. The connecting shaft 7 is vertically arranged, and the connecting shaft 7 can rotate to penetrate the first connecting portion 131. The connecting shaft 7 is fixedly connected to the limiting plate 2. The side wall of the connecting shaft 7 has a limiting portion 71 protruding outward, and the limiting portion 71 abuts against the bottom surface of the first connecting portion 131. The limiting of the limiting plate 2 and the limiting portion 71 by the first connecting portion 131 can limit the movement of the connecting shaft 7 in the vertical direction, so that the connecting shaft 7 has only the degree of freedom of rotation. The limiting plate 2 is connected to the first connecting portion 131 through the connecting shaft 7.

[0035] In some embodiments, see Figure 1 , the number of locking assemblies is two. This can ensure the reliability of the connection between the disassembly portion 112 and the fixing portion 111. In this embodiment, the number of the first connecting portions 131 is two, and the two first connecting portions 131 are respectively located at two locking assemblies, and the limiting portion 71 is rotatably connected to the first connecting portions 131 at the location.

[0036] In some embodiments, the above-mentioned characteristic mold body 1 can be used as follows Figure 1 See the structure shown. Figure 1 The lower end of the mold body 1 has a second folded edge 14 facing outwards, and the mold body 1 also has a reinforcing rib 15 between the first folded edge 13 and the second folded edge 14. This can further increase the strength of the mold body 1.

[0037] In some embodiments, see Figure 4 and Figure 5 , a threaded hole is provided on the bottom wall of the mold body 1, and a cylindrical groove 16 is provided on the bottom surface of the mold body 1 coaxially arranged with the threaded hole. The concrete test block casting mold also includes a fixing bolt 8. The screw rod of the fixing bolt 8 is threadedly connected in the threaded hole, and the head of the fixing bolt 8 is located in the cylindrical groove 16. The fixing bolt 8 blocks the threaded hole. When the casting is completed, the fixing bolt 8 is withdrawn from the threaded hole, and then the concrete test block can be pushed out of the mold body 1 through the threaded hole. For example, a tool such as a stick can be used, or high-pressure gas can be blown into the mold body 1 through the threaded hole. The cylindrical groove 16 can be used to connect with the air nozzle of the high-pressure gas source.
