Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, and in particular to a test mold for concrete testing. Background Technology

[0002] To obtain the strength of concrete prepared with different formulations during production, concrete is poured into rectangular molds and then cured to solidify. After solidification, the concrete's strength is tested. Currently used molds have a simple structure, consisting of five welded plates. To facilitate demolding during pouring, a release agent is often applied to the inner wall. Although the inner wall contains the release agent, the formed concrete block remains in close contact with the mold's inner wall, making demolding difficult. A common method is to knock the mold to demold, but this method easily deforms the mold. Utility Model Content

[0003] This invention provides a concrete testing mold to overcome the shortcomings of the prior art, solve the problem of inconvenient demolding, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A concrete testing mold includes a bottom component, side components on both sides of the bottom component, an end component between the two ends of the side components, and a fixing mechanism on the lower side of the bottom component.

[0005] Furthermore, the bottom component includes a long rectangular plate with rectangular end posts on both sides of the rectangular plate. The rectangular end posts on the same side are spaced apart. A connecting rod is threaded through the rectangular end posts on the same side. Nuts are threaded to both ends of the connecting rod. The inner end of the nut abuts against the outer end of the rectangular end post. A pair of insertion ports are opened at both ends of the rectangular plate. The insertion ports are located on the inner side of each rectangular end post.

[0006] Furthermore, a base support block is formed on the lower side of the rectangular end post.

[0007] Furthermore, the side component includes a side plate, the lower end of which is formed with a pair of lugs that are inserted into a socket. The outer ends of the side plate are formed with outer end posts, and the outer wall of the side plate is formed with a lower extension protrusion. A waist-shaped hole is opened on the lower extension protrusion, and the connecting rod passes through the waist-shaped hole. A slot is formed at the location of the side plate and the outer end posts. The slot has a right-angled trapezoidal structure, and a notch is opened at the inner end of the slot.

[0008] Furthermore, the end component includes an end plate, on the outer wall of which a retaining strip is formed. The two sides of the retaining strip are right-angled trapezoidal structures. The retaining strip passes through a retaining groove, and the retaining groove matches the shape of the retaining strip. The end plate passes through a notch. An L-shaped buckle is formed on the outer wall of the end plate. A pair of insertion holes are opened at the lower end of the L-shaped buckle. The L-shaped buckle is located on the outside of the rectangular plate.

[0009] Furthermore, the fixing mechanism includes multiple downward extension rods fixed to the bottom of the rectangular plate. A pull-down plate is sleeved on the downward extension rod, and a pull-down screw is threadedly connected to the pull-down plate. The upper end of the pull-down screw is connected to the bottom of the rectangular plate through a rotating seat. An end cap is provided at the lower end of the pull-down screw. A pair of strip holes are opened at both ends of the pull-down plate, and a movable pin passes through the strip holes. The lower end of the movable pin at the same end is fixed to a movable column by a pin. The two ends of the movable column are threadedly connected to limit plugs, and the limit plugs are inserted into the insertion holes.

[0010] Furthermore, a pair of limit screws are fixed to both ends of the pull-down plate by threads. A movable lower plate is fitted on the limit screws at the same end. A pair of elongated holes are opened on the movable lower plate. The limit screws pass through the elongated holes. An end crossbar is welded to the outer end of the movable lower plate. The two ends of the end crossbar are connected to an inner locking rod by threads. The inner end of the inner locking rod is inserted into the lower end of the waist-shaped hole.

[0011] The advantages of the above technical solution are: The test mold provided by this utility model has side components that are rotatably mounted on the bottom component, and end components that are pluggable and detachable between the side components. This detachable and rotatable design facilitates the separation of the side components and end components from the test piece, reducing the difficulty of demolding.

[0012] Considering that vibration is required during the implementation of this utility model, a corresponding fixing mechanism is also provided in order to improve the stability of the connection between the components and avoid affecting the casting and forming of the specimen. During fixing, the side components are limited by the inner locking rod, and the end components are limited by the limiting rod, so as to improve the connection effect between the components.

The rectangular end posts 16 on the same side are spaced apart. A connecting rod 13 is passed through the rectangular end posts 16 on the same side. Nuts 14 are threaded to both ends of the connecting rod 13. The inner end of the nut 14 abuts against the outer end of the rectangular end post 16. A pair of insertion ports 15 are opened at both ends of the rectangular plate 10. The insertion ports 15 are located inside each rectangular end post 16. A bottom support block 11 is formed on the lower side of the rectangular end post 16.

[0021] The side component 2 includes a side plate 20. A pair of lugs 26 are formed at the lower end of the side plate 20. The lugs 26 are inserted into the socket 15. The outer ends of the side plate 20 are formed with outer end posts 21. The outer wall of the side plate 20 is formed with a lower extension protrusion 24. A waist-shaped hole 25 is opened on the lower extension protrusion 24. The connecting rod 13 passes through the waist-shaped hole 25. A slot 23 is formed at the position of the side plate 20 and the outer end post 21. The slot 23 has a right-angled trapezoidal structure. A notch 22 is opened at the inner end of the slot 23.

[0022] The end component 3 includes an end plate 30. A retaining strip 31 is formed on the outer wall of the end plate 30. The two sides of the retaining strip 31 are right-angled trapezoidal structures. The retaining strip 31 passes through the retaining groove 23, and the retaining groove 23 matches the shape structure of the retaining strip 31. The end plate 30 passes through the notch 22. An L-shaped buckle plate 32 is formed on the outer wall of the end plate 30. A pair of insertion holes 33 are opened at the lower end of the L-shaped buckle plate 32. The L-shaped buckle plate 32 is located on the outside of the rectangular plate 10.

[0023] The fixing mechanism 4 includes multiple downward extension rods 40 fixed to the bottom of the rectangular plate 10. A pull-down plate 42 is sleeved on the downward extension rod 40. A pull-down screw is threadedly connected to the pull-down plate 42. The upper end of the pull-down screw is connected to the bottom of the rectangular plate 10 through a rotating seat. An end cap 41 is provided at the lower end of the pull-down screw. A pair of strip holes 43 are respectively opened at both ends of the pull-down plate 42. A movable pin 44 passes through the strip hole 43. A movable column 470 is fixed to the lower end of the movable pin 44 at the same end by a pin. The two ends of the movable column 470 are threadedly connected to a limit plug 45. The limit plug 45 is inserted into the insertion hole 33. A pair of limiting screws 46 are fixed to both ends of the pull-down plate 42 by threads. A movable lower plate 47 is sleeved on the limiting screws 46 at the same end.

An end crossbar 50 is welded to the outer end of the movable lower plate 47. The two ends of the end crossbar 50 are connected to the inner locking rod 51 by threads. The inner end of the inner locking rod 51 is inserted into the lower end of the waist-shaped hole 25.

[0024] In this embodiment, demolding is the reverse process of demolding. During demolding, the operator rotates the side plate 20 upwards to make it vertical, then moves it downwards to insert the lug 26 into the socket 15. The end plate 30 is then inserted between the side plates 20, with the retaining strip 31 inserted into the slot 23 until the limiting rod 45 is aligned with the socket 33. The operator then inserts the inner end of the inner locking rod 51 into the oblong hole 25 and the limiting rod 45 into the socket 33. The operator then rotates the pull rod to move the end plate 30 and side plate 20 downwards, causing their lower ends to abut against the upper wall of the rectangular plate 10. A release agent is then applied to the inner wall, followed by concrete pouring, vibration, and curing until the concrete is fully formed.

[0025] During demolding, the operator first reverses the pull rod to cancel the pull-down action of the limit rod and the inner locking rod 51, and then pulls them out from the waist-shaped hole 25 and the insertion hole 33 respectively. Then, by acting on the lower end of the lug 26 and the lower end of the L-shaped buckle 32, until the concrete block and the side plate 20 and the end plate 30 are separated, the end plate 30 is then pulled out, while the side plate 20 is rotated outward, and then the concrete is detached from the rectangular plate 10.
