Description

Technical Field

[0001] The utility model relates to the field of concrete test block preparation, in particular to a concrete test block preparation mould. Background Art

[0002] The existing concrete test block preparation method is such as the scheme with authorization announcement number CN220719760U. During installation, the fixing plate 1 2 and the fixing plate 2 3 are fixedly connected through the support plate 2 31 and the support plate 1 21, and the threaded groove 23 is inserted into the inside of the support plate 1 21 and the support plate 2 31, and fixed by twisting, so that the fixing plate 1 2 and the fixing plate 2 3 are spliced ​​and fixed; during removal, the cement block inside the fixing plate 2 3 is squeezed out by squeezing the moving column 55 and the squeezing column 56 to move toward the inside of the fixing plate 2 3. Although the above method basically realizes installation and removal, there are the following problems:

[0003] 1. During installation, two adjacent fixing plates are fixed by bolts after splicing, which requires a large extrusion force and is more laborious.

[0004] 2. During disassembly, if there is no bonding, the above method can be used. If bonding occurs, the above method cannot be used. When prying is used, the fixing plate will bend, and concrete will overflow during the next use. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a concrete test block preparation mold, which effectively solves the problem of difficult installation and side bending and deformation.

[0006] The technical solution is a concrete test block preparation mold, comprising a bottom plate, four vertical plates are mounted on the bottom plate, the four vertical plates form a rectangular frame, the inner sides of two side edges of the vertical plates are chamfered, two adjacent vertical plates are chamfered to fit each other, the vertical plates can only move horizontally inward and outward, first sinking grooves arranged up and down are opened on the outer sides of two side edges of the vertical plates, an L-shaped plate projected in an L shape on a horizontal plane is inserted in the first sinking grooves of two adjacent vertical plates, and each end of the L shape of the L-shaped plate can only move horizontally inward and outward relative to the first sinking groove;

[0007] When the two ends of the L-shape of the L-shaped plate move horizontally into the first groove, the L-shaped plate causes the two adjacent vertical plates to move horizontally inward and chamfer to fit together, and the two vertical plates can be fixed after the chamfering and fitting; when the two ends of the L-shape of the L-shaped plate move horizontally outward of the first groove, the L-shaped plate causes the two adjacent vertical plates to move horizontally outward and separate.

[0008] The upper surface of the bottom plate is provided with four second grooves in the inner and outer directions, and the four second grooves are evenly distributed about the central circumference of the bottom plate. A fixed block is fixed on the lower side of the outer end surface of the vertical plate, and the lower end of the fixed block protrudes out of the lower end surface of the vertical plate. The lower end of the fixed block is placed in the second groove. After the vertical plate is translated inward, the fixed block contacts the inner end of the second groove.

[0009] A rectangular countersunk hole is provided at the bottom of the middle of the first countersunk groove, and a rectangular frame is fixed in the middle of both ends of the L-shaped plate, and the rectangular frame can be placed in the rectangular countersunk hole and move in and out;

[0010] The middle part of the rectangular countersunk hole rotates with an axis perpendicular to the rotating shaft of the corresponding vertical plate. A circular ring is fixed on the outer edge of the rotating shaft located in the rectangular countersunk hole. Two fan-shaped blocks are fixed on the outer edge of the circular ring. The angle between the centers of the two fan-shaped blocks and the circular ring is 90 degrees. The circular ring and the fan-shaped blocks are located in a rectangular frame. When the middle part of the outer edge of one of the fan-shaped blocks contacts one of the inner and outer sides of the rectangular frame, the outer edge of the circular ring contacts the other side of the rectangular frame.

[0011] The outer end of the rotating shaft passes through the vertical plate and is placed on the outer side of the vertical plate. A swing rod parallel to the vertical plate is fixed to one end of the rotating shaft placed on the outer side of the vertical plate, and the swing rod can drive the rotating shaft to rotate.

[0012] Two C-shaped blocks are fixed on the outer end surface of each vertical plate. The two C-shaped blocks are arranged on the left and right and are located on the inner sides of the two rotating shafts on the corresponding side vertical plates. After the swing arm swings downward, the end of the swing arm away from the rotating shaft can be placed in the C-shaped block and fixed.

[0013] The utility model uses the L-shaped plate to push the side edge of the vertical plate outward and separate it from the concrete test block through the first sinking groove as a whole, so that the vertical plate will not bend and deformed due to the side edge of the vertical plate being pried by the upper side after the concrete is bonded to the side edge of the vertical plate, thereby causing the concrete to overflow from the gap when it is used next time; the installation and separation of the vertical plate can be achieved by only swinging the surrounding swing rods up and down, and the operation is simple and convenient.

[0020] The specific implementation of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] Depend on Figures 1 to 6 The utility model includes a bottom plate 1, on which four vertical plates 2 are mounted, and the four vertical plates 2 form a rectangular frame 8, the inner sides of the two side edges of the vertical plates 2 are chamfered, and two adjacent vertical plates 2 are chamfered to fit each other, and the vertical plates 2 can only move horizontally inward and outward, and the outer sides of the two side edges of the vertical plates 2 are provided with first sinking grooves 3 arranged up and down, and an L-shaped plate 4 projected in an L shape on a horizontal plane is inserted in the first sinking grooves 3 of two adjacent vertical plates 2, and each end of the L shape of the L-shaped plate 4 can only move horizontally inward and outward relative to the first sinking groove 3;

[0022] When the two ends of the L-shape of the L-shaped plate 4 move horizontally into the first groove 3, the L-shaped plate 4 causes the two adjacent vertical plates 2 to move horizontally inward and chamfer to fit together, and after the chamfering and fitting, the two vertical plates 2 can be fixed; when the two ends of the L-shape of the L-shaped plate 4 move horizontally outward of the first groove 3, the L-shaped plate 4 causes the two adjacent vertical plates 2 to move horizontally outward and separate.

[0023] The upper end surface of the bottom plate 1 is provided with four second grooves 5 in the inner and outer directions, and the four second grooves 5 are evenly distributed about the central circumference of the bottom plate 1. A fixing block 6 is fixed to the lower side of the outer end surface of the vertical plate 2, and the lower end of the fixing block 6 protrudes out of the lower end surface of the vertical plate 2. The lower end of the fixing block 6 is placed in the second groove 5. After the vertical plate 2 is translated inward, the fixing block 6 contacts the inner end of the second groove 5.

[0024] A rectangular countersunk hole 7 is provided at the bottom of the middle of the first countersunk groove 3, and a rectangular frame 8 is fixed at the middle of both ends of the L-shaped plate 4, and the rectangular frame 8 can be placed in the rectangular countersunk hole 7 and move in and out;

[0025] The middle of the rectangular countersunk hole 7 is rotated with a rotating shaft 9 whose axis is perpendicular to the corresponding vertical plate 2. A circular ring 10 is fixed to the outer edge of the rotating shaft 9 located in the rectangular countersunk hole 7. Two sector blocks 11 are fixed to the outer edge of the circular ring 10. The angle between the centers of the two sector blocks 11 and the circular ring 10 is 90 degrees. The circular ring 10 and the sector blocks 11 are located in the rectangular frame 8. When the middle of the outer edge of one of the sector blocks 11 contacts one of the inner and outer sides of the rectangular frame 8, the outer edge of the circular ring 10 contacts the other side of the rectangular frame 8.

[0026] When the middle of the outer edge of one of the fan-shaped blocks 11 rotates toward the inside of the rectangular frame 8, the fan-shaped block 11 moves the vertical plate 2 into the sink groove through the rectangular frame 8, and the chamfers of the two adjacent vertical plates 2 approach and touch each other; when the middle of the outer edge of one of the fan-shaped blocks 11 rotates toward the outside of the rectangular frame 8, the fan-shaped block 11 moves the vertical plate 2 out of the sink groove through the rectangular frame 8, and the two adjacent vertical plates 2 move away from each other.

[0027] The outer end of the rotating shaft 9 passes through the vertical plate 2 and is placed outside the vertical plate 2 . A swing rod 12 parallel to the vertical plate 2 is fixed to the end of the rotating shaft 9 placed outside the vertical plate 2 . The swing rod 12 can drive the rotating shaft 9 to rotate.

[0028] Two C-shaped blocks 13 are fixed to the outer end surface of each vertical plate 2. The two C-shaped blocks 13 are arranged on the left and right and are located on the inner sides of the two rotating shafts 9 on the corresponding side vertical plates 2. After the swing rod 12 swings downward, the end of the swing rod 12 away from the rotating shaft 9 can be placed in the C-shaped block 13 and fixed;

[0029] When the swing rod 12 swings downward, the middle of the outer edge of one of the fan-shaped blocks 11 rotates toward the inside of the rectangular frame 8. When the swing rod 12 is placed in the C-shaped clamping block 13, the two adjacent vertical plates 2 are fixed; when the swing rod 12 swings upward, the middle of the outer edge of the other fan-shaped block 11 rotates toward the outside of the rectangular frame 8, and the two adjacent vertical plates 2 are separated.

[0030] When the utility model is used, the vertical plate 2 is placed on the bottom plate 1, and the lower end of each fixing block 6 on the vertical plate 2 is placed in a second sink 5, and then the swing rods 12 are swung downward in sequence to be placed in the C-shaped clamping block 13 for fixing. When all the swing rods 12 are fixed, the chamfers of the two adjacent vertical plates 2 are fitted together, and the swing rods 12 are fixed inwardly through the rotating shaft 9 and the rectangular frame, so that the L-shaped plate 4 is fixed, and then the two adjacent vertical plates 2 are fixed;

[0031] After that, concrete is placed inside the vertical plate 2 and solidified. When the concrete test block is prepared, the vertical plate 2 is removed. The operation method is to first select one of the vertical plates 2, and find two swing rods 12 on the two adjacent vertical plates 2 close to the selected vertical plate 2, so that the two swing rods 12 swing upward, and the swing rods 12 move the L-shaped plate 4 outward of the first sinking groove 3 through the fan-shaped block 11 and the rectangular frame 8, so that the selected vertical plate 2 moves horizontally outward to separate from the concrete test block. Since the L-shaped plate 4 pushes the side of the entire vertical plate 2 to move outward through the sinking groove, it can prevent the problem of bending and deformation of the side of the vertical plate 2, which makes it difficult to use in the later stage;

[0032] Then select other vertical panels 2 in turn and repeat the above operation until the concrete test block is completely detached.

[0033] 1. The utility model uses the L-shaped plate 4 to push the side of the vertical plate 2 outward and separate it from the concrete test block through the first sinking groove 3, so that the vertical plate 2 will not bend and deform due to the side of the vertical plate 2 being pried by the upper side after the concrete is bonded to the side of the vertical plate 2, thereby causing the concrete to overflow from the gap when it is used next time.

[0034] 2. The utility model can realize the installation and separation of the vertical board 2 only by swinging the surrounding swing rods 12 up and down, and the operation is simple and convenient.
