Technical Field

[0001] This utility model relates to the field of mortar waterproofing testing technology, and in particular to an integrated machine for molding and demolding mortar anti-seepage test specimens. Background Technology

[0002] In recent years, with the acceleration of urbanization, the scale and complexity of waterproofing in the construction industry have increased, which has put forward higher requirements for the impermeability of mortar. The frequency of mortar impermeability tests in relevant research units, production units and construction units is constantly increasing.

[0003] In existing technologies, mortar impermeability testing requires applying a layer of sealant to the sides of the specimen and the inner surface of the test mold before pressing the specimen into the mold to ensure both sides are flush. Different sealants, pressing methods, and application thicknesses result in varying degrees of difficulty in pressing the specimen into the mold, mold assembly efficiency, and specimen sealing performance. Furthermore, after the test, due to factors such as sealant curing and compression, the sealant can adhere the specimen to the mold, making demolding difficult. Different people may use different demolding methods, potentially causing scratches or dents on the surface of the mold or specimen. To address these issues, this application proposes an integrated molding and demolding machine for mortar impermeability specimens. Utility Model Content

[0004] Based on this, in order to solve the problems existing in the prior art, this application provides a mortar anti-permeability specimen molding and demolding integrated machine, including a base;

[0025] like Figure 1-3 As shown in the figure, this application provides a mortar anti-permeability specimen molding and demolding integrated machine, including: a base 1;

[0026] Lifting device 2, which is installed on base 1, and lifting rod 21 is installed inside lifting device 2;

[0027] The top plate 3 is positioned above the lifting device 2. Both ends of the top plate 3 are connected to the base 1 via a support rod 4. The lifting device 2 is located between the two support rods 4. The top plate 3 has a through hole 31, which includes a first through hole 311 and a second through hole 312. The second through hole 312 is located above the first through hole 311. The diameter of the first through hole 311 is larger than the diameter of the second through hole 312. The lifting rod 21 is coaxially arranged with the through hole 31. The end of the lifting rod 21 has a groove 211.

[0028] A support plate 6 has a pad 61 fixedly installed at the center of one side of the support plate 6. The shape and size of the pad 61 match the groove 211. The support plate 6 can be detachably installed in the groove 211 through the pad 61.

[0029] In this embodiment, the lifting device 2 is a jack, and the jack is equipped with a handle 22. By shaking the handle 22, the lifting rod 21 can be extended or retracted from the jack, thereby driving the support plate 6 to rise or fall. The lifting device 2 can stably apply upward pressure.

[0030] The cross-section of the through hole 31 is circular, and the thickness of the top plate 3 is 10mm; the diameter of the first through hole 311 is 95mm and the height is 5mm, and the diameter of the second through hole 312 is 82mm and the height is 5mm; it should be noted that the test mold used in this application is a cylindrical shape with an outer diameter of 93.5mm, while the upper end diameter of the mortar specimen is 70mm and the lower end diameter is 80mm. The internal shape and size of the test mold are consistent with those of the mortar specimen, so both the upper and lower surfaces of the test mold can be embedded in the through hole 31 of the top plate 3;

[0031] The support plate 6 is circular and can support the test piece. The support plate 6 has a circular scale line with a diameter of 95mm, which facilitates the quick placement of the test mold.

[0032] The diameter of the pad 61 is 65mm, and the height of the pad 61 is greater than the length of the experimental mold plus the thickness of the top plate 3.

[0033] like Figure 2 As shown, in the first state, the pad 61 is located in the groove 211;

[0034] like Figure 3 As shown, in the second state, the pad 61 is located above the support plate 6;

[0035] The working principle is as follows: The top of the jack lifting rod 21 supports the support plate 6, which can move up and down with the jack lifting rod 21. When the test mold is installed, the pad block 61 is located in the groove 211. First, the test mold is placed on the outside of the specimen with the side coated with sealant. After the sealant is applied, the overall diameter of the specimen will be slightly larger, resulting in the overall size of the specimen being larger than the inner diameter of the test mold. At this time, the test mold is placed on the outside of the specimen, and part of the lower end of the specimen will protrude from the test mold. The lower end face of the test mold and the lower end face of the test specimen are placed inside the circular scale line of the support plate 6. The scale line of the support plate 6 is aligned with the 95mm first through hole 311 of the top plate 3. Then, the lever 22 of the lifting device 2 is manually pressed. The lifting device 2 drives the support plate 6 to rise continuously. The upper end face of the test mold is embedded in the through hole 31 of the top plate 3. The pressure is continued to be applied so that the test specimen protruding from the lower end face of the test mold is continuously pressed into the test mold until the test specimen is flush with both ends of the test mold, thus completing the molding of the impermeability test specimen.

[0036] When dismantling the test mold, flip the support plate 6 so that the pad 61 is above the support plate 6. Flip the test mold containing the test specimen inside and place it upside down in the circular scale line of the support plate 6 so that the pad 61 is aligned with the test specimen inside the test mold. Then, manually press the lever 22 of the lifting device 2. The support plate 6 and the pad 61 rise continuously. The lower end face of the test mold is embedded in the through hole 31 of the top plate 3 and is restricted from moving by the first through hole 311. Continue to apply pressure. At this time, the pad 61 continues to move upward. First, it pushes the test specimen out of the test mold. Then, it continues to push the test specimen out from the second through hole 312, thus completing the demolding of the test specimen from the test mold.

[0037] This application enables the rapid loading or unloading of mortar anti-permeability specimens with appropriate pressure. The lifting device 2 makes loading or unloading easier, and the stable pressure makes it less likely to cause scratches and dents on the surface of the specimens. Furthermore, the invention has a stable structure, small size, and simple and convenient operation, which can greatly improve the loading and unloading efficiency of mortar specimens, while ensuring the sealing of the specimens and the test mold, and improving the accuracy of the test.

[0038] In one embodiment, a boss 32 is provided on the side of the top plate 3 near the support plate 6, and a through hole 31 passes through the boss 32.

[0039] In this embodiment, the boss 32 is provided, and the side of the boss 32 closest to the support plate 6 is parallel to the support plate 6.

[0040] In one embodiment, a fixing plate 5 is further included, with the middle part of the fixing plate 5 fixedly sleeved on the outer wall of the lifting device 2, and the two ends of the fixing plate 5 slidably sleeved on the support rod 4 respectively.

[0041] In this embodiment, by fitting a fixing plate 5 on the outer wall of the lifting device 2, the lifting device 2 can be prevented from moving when the lever 22 is cranked, and the structural stability can also be increased. The fixing plate 5 is slidably set with the support rod 4, so that the height of the fixing plate 5 is adjustable and the lifting device 2 at different heights can be fixed.

[0042] In one embodiment, the sidewalls of the parts of the fixing plate 5 that are connected to the support rod 4 at both ends are provided with screw holes, and nuts 51 are threaded into the screw holes. The end of the nut 51 that extends into the screw hole abuts against the outer wall of the support rod 4.

[0043] In this embodiment, the nut 51 can be tightened after the fixing plate 5 is fixed to the lifting device 2, so that the fixing plate 5 is fixed to the support rod 4, preventing the lifting device 2 from shifting due to the sliding of the fixing plate 5 during the test.

[0044] In one embodiment, a pressure gauge 7 is also included, which is disposed on one side of the lifting device 2.

[0045] In this embodiment, by setting pressure gauge 7, the value of pressure gauge 7 can be observed during the pressurization process, avoiding excessive pressure caused by factors such as uneven or excessively thick application of sealing material, which could damage the internal structure of the specimen and lead to data distortion.

[0046] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
