Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a concrete test block auxiliary demoulding device. Background Art

[0002] In the field of construction engineering technology, in order to test the performance of concrete, it is often necessary to use a standard concrete test mold to make a standard test block. Currently, there are two types of concrete test molds: steel molds and plastic molds.

[0003] Among them, plastic molds are mostly made of engineering plastics, and the bottom plate of the test mold is opened with small holes. It is an integrated plastic mold. There are two ways to demould: one is manual vibration demoulding. Manual demoulding mainly relies on manpower to collide with the mold carrying the test block. Under the action of the collision force, the test block and the mold are separated. The problem is that both the test mold and the test block are greatly damaged; the second is to use the air pressure provided by the air pump to impact the test block through the small holes in the bottom plate of the test mold to demould it. For example, a simple concrete test block demoulding device disclosed in Chinese patent number CN209408870U adopts the method of pressing and impacting the test block. The problem with this demoulding method is that the test block and the mold are too dense, and the air pressure cannot flush the test block out. Violent demoulding will damage the plastic test mold. At the same time, damage to the test block cannot guarantee the test mold size accuracy and surface roughness required by the standard. Utility Model Content

[0028] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0029] See also Figure 1 , is a structural schematic diagram of a preferred embodiment of a concrete test block auxiliary demoulding device provided by the utility model.

[0030] A concrete test block auxiliary demoulding device is used to remove a concrete test mold made of engineering plastics and a test block in a plastic mold, comprising:

[0031] A plurality of first limiting members 3, wherein the plurality of first limiting members 3 are used to enclose and form a square limiting cavity, and the limiting cavity is used to pass the test block;

[0032] A plurality of second limiting members 4, wherein the plurality of second limiting members 4 are arranged on the first limiting member 3 in a one-to-one correspondence, wherein the second limiting member 4 comprises a first side plate and a second side plate connected perpendicularly to each other, wherein the first side plate is staggered relative to the first limiting member 3 in a direction away from the limiting cavity and forms an exposed locking section 2 on the first limiting member 3, wherein the locking section 2 is used to lock the outlet end of the plastic mold; and the plurality of second side plates enclose a locking cavity, wherein the locking cavity is used to limit the side wall of the plastic mold;

[0033] A support member 1, wherein the support member 1 is used to support the first limiting member 3;

[0034] A plurality of third limiting members 5 are enclosed to form a base ring, and the base ring is used to support the support member 1.

[0035] The utility model not only forms a locking section 2 on the first limiting member 3 to abut the port of the plastic mold by staggering the second limiting member 4 and the first limiting member 3, but also forms a locking cavity by the second side plate of the second limiting member 4 to lock the side wall of the plastic mold, thereby buckling the plastic mold into the locking cavity. The plastic mold and the test block accelerate to fall under the action of gravity. The locking section 2 locks the mold while the test block continues to be demolded from the mold and falls, which makes demolding faster and causes less damage to the test block. It should be noted that if the test block is stuck in the plastic mold, the auxiliary demolding device can be gently tapped, such as tapping the support member 1 to accelerate the test block to fall off, so as to avoid direct tapping of the test block to cause damage to the test block.

[0036] In one embodiment of the present invention, the support member 1 can be connected to a vibration motor, and the vibration motor can drive the auxiliary demoulding device to continuously vibrate slightly, which is beneficial to improving the smoothness of demoulding of the test block.

[0037] Preferably, please refer to Figure 1 and Figure 2 As shown, the first limiting member 3 and the supporting member 1 both include angle steels, and the first limiting member 3 and the supporting member 1 are connected by bolts or welding.

[0038] Specifically, the support members 1 are arranged in an array and are used to support a plurality of first limiting members 3, and the enclosed cavity formed by the plurality of support members 1 is not smaller than the limiting cavity, and the enclosed cavity is used to pass the test block.

[0039] It is understandable that the use of angle steel is convenient for obtaining materials on site, which is conducive to reducing production costs and is also convenient for processing and assembly. Multiple support members 1 can play a role in strengthening support, and reinforcing ribs can be arranged between adjacent support members 1. The reinforcing ribs can be made of on-site steel plates, which can further improve the overall stability of the device.

[0040] Preferably, please refer to Figure 1 and Figure 2 As shown, a partial segment of the first side plate extends out of the first limiting member 3 in a direction away from the limiting cavity and forms a handle.

[0041] It is understandable that the exposed portion of the first side panel can be used as a handhold to facilitate manual handling of the device. The second stopper 4 and the first stopper 3 are staggered in the width direction to form the clamping section 2 and the clamping cavity at the same time. The second stopper 4 can also form a handle, realizing multiple functions and having outstanding practical value.

[0042] Preferably, please refer to Figure 1 and Figure 2 As shown, the length of the second limit member 4 is less than the length of the first limit member 3, and the concrete test block auxiliary demoulding device also includes an extension frame for detachably sleeved on the second side plate, and the extension frame is extended vertically upward.

[0043] It is understandable that by extending the height of the second side plate through the extension frame, when the mold falls from a higher height, the extension frame is used to limit the position, ensuring that the mold can fall smoothly. The extension frame can be easily removed for storage, which is convenient for the transportation of the entire device.

[0044] Preferably, please refer to Figure 1 and Figure 3 As shown, a buffer plate 6 is provided inside the base ring, and the buffer plate 6 is used to receive the test block falling along the limiting cavity.

[0045] It can be understood that the buffer plate 6 can protect the falling test block and prevent the test block from being damaged by a heavy collision.

[0046] Preferably, please refer to Figure 1 and Figure 3 As shown, the third limiting member 5 comprises an angle steel, a limiting hole is provided on the third limiting member 5, and the buffer plate 6 is detachably disposed in the limiting hole.

[0047] Specifically, a pair of opposite third limiting members 5 among the plurality of third limiting members 5 are respectively provided with a first limiting hole 9 and a second limiting hole 10, the first end of the buffer plate 6 passes through the first limiting hole 9 and the second limiting hole 10 in sequence, the second end of the buffer plate 6 is provided with a limiting platform 7, the width of the limiting platform 7 is greater than the width of the first limiting hole 9, and a handle 8 is provided on the limiting platform 7.

[0048] It is understandable that the buffer plate 6 is inserted into a pair of third limiting members 5 for detachable installation, so as to facilitate the extraction of the buffer plate 6 to discharge the test block. The limiting platform 7 can position the buffer plate 6, and the handle 8 on the limiting platform 7 facilitates the disassembly and assembly of the buffer plate 6.

[0049] In another solution of the preferred embodiment of the utility model, the buffer plate 6 is hinged to the third limiting member 5 .

[0050] It can be understood that since the buffer plate 6 is hingedly installed, when the test block needs to be discharged, it is only necessary to lift the demoulding device as a whole through the second limit member 4. Under the action of gravity, the test block presses down the free end of the buffer plate 6 and then slides out of the buffer plate 6, and the discharge operation can be conveniently completed.

[0051] Preferably, please refer to Figure 1 and Figure 3 As shown, the buffer plate 6 includes a rubber pad, and an array of strip grooves is formed on the buffer plate 6.

[0052] It should be noted that the direction of the strip groove is preferably the direction in which the test block slides relative to the buffer plate 6 . The strip groove can improve the relative sliding smoothness between the test block and the buffer plate 6 , and facilitate the discharge of the test block.
