Description

Technical Field

[0001] This application relates to the field of concrete testing, and in particular to a release base for an anti-seepage mold. Background Technology

[0002] The permeability resistance of concrete is an important performance indicator for testing concrete, and it is usually tested using a concrete permeability tester. Before conducting the permeability test, the concrete specimen usually needs to be cured and the surface dried. After that, a layer of molten sealant is applied to the convex side of the specimen. Then, the concrete specimen is pressed into a specimen sleeve that has been preheated in an oven. After cooling, the concrete specimen and the specimen sleeve are tested. After the permeability test is completed, the concrete specimen and the specimen sleeve need to be separated. Currently, the specimen sleeve and the concrete specimen are usually placed on the worktable of a press, and several pads are placed around the lower circumference of the specimen sleeve. The concrete specimen is then pressed out of the specimen sleeve by the press. However, using pads to support the specimen sleeve can easily lead to instability and deviation of the pads during the pressing of the concrete specimen by the press, posing a significant safety hazard. Utility Model Content

[0003] To improve the safety of pressing concrete test blocks out of the test specimen sleeve by the press, this application provides a demolding base and demolding device for an anti-permeability mold.

[0004] This application provides a demolding base for an anti-seepage mold, which adopts the following technical solution:

[0005] A demolding base for an anti-permeability mold includes a lower base and a support member placed on the lower base. The support member includes multiple vertically arranged support tubes and connecting rods connecting adjacent support tubes. There are three support tubes. The support member is generally in the shape of an equilateral triangle. Each support tube has a support end face for supporting the bottom of the specimen sleeve and a limiting protrusion for abutting against the outer circumferential surface of the mounting protrusion of the specimen sleeve. The limiting protrusion is integrally formed with the support tube and is an arc-shaped protrusion. Both sides of the limiting protrusion have abutting side edges that abut against the mounting protrusion.

[0006] By adopting the above technical solution, when demolding concrete test blocks using a press and the aforementioned anti-permeability mold demolding base, firstly, the lower base is installed on the test platform of the press. Then, the support is placed on the lower base, and next, the specimen sleeve containing the concrete test specimen is installed onto the support. At this time, the support tube of the support is supported on the specimen sleeve, and the support tube and the concrete test specimen are staggered. The limiting protrusion on the support tube is connected to the outer circumference of the mounting protrusion ring of the specimen sleeve, thereby limiting the specimen sleeve in the horizontal direction. Finally, the press is started, pressing the concrete test specimen out of the specimen sleeve. During the process of the press pressing the concrete test specimen out of the specimen sleeve, the support of the support provides ideal support for the specimen sleeve, reducing the probability of the specimen sleeve tipping over and improving the safety of the press pressing the concrete test block out of the specimen sleeve.

[0007] Optionally, the bottom of the support tube is provided with a mounting base.

[0008] By adopting the above technical solution, the installation chassis setting increases the contact area between the support and the lower base, making the support effect of the support on the specimen sleeve more ideal, and reducing the pressure of the support on the lower base when the press presses the concrete specimen out of the time sleeve, which helps to extend the service life of the lower base.

[0009] Optionally, the mounting chassis is provided with a plurality of weight-reducing through holes penetrating the upper and lower surfaces, and the plurality of weight-reducing through holes are evenly arranged circumferentially on the mounting chassis.

[0010] By adopting the above technical solution, the weight-reducing through hole helps to reduce the weight of the support, thus making it easier for operators to place the support on the lower base.

[0011] Optionally, the lower base is provided with a positioning groove for the mounting chassis to be arranged.

[0012] By adopting the above technical solution, the support can be placed on the lower base through the cooperation of the positioning groove and the mounting chassis, reducing the probability of the support shifting during the demolding process of the concrete specimen.

[0013] Optionally, the lower base includes a lower base plate and an elastic support assembly mounted on the lower base plate for elastically supporting the concrete test block. The elastic support assembly includes a support plate, a telescopic tube connecting the support plate and the lower base plate, and a support spring sleeved on the outside of the telescopic tube. The bottom end of the support spring abuts against the lower base plate, and the top end of the support spring abuts against the support plate. The telescopic tube includes an upper tube fixed to the bottom of the support plate and a lower tube fixed to the lower base plate for sliding of the upper tube.

[0014] By adopting the above technical solution, the elastic support component ensures that the support plate is always in contact with the bottom of the concrete specimen before and during demolding, thus preventing the concrete specimen from directly impacting the lower base and causing debris to fly around during demolding.

[0015] Optionally, the lower base is further provided with a dust cover arranged on the outside of the support spring. The dust cover includes an upper mounting ring installed on the outer periphery of the support plate, a lower mounting ring fixed on the lower base plate, and a telescopic sleeve connecting the upper mounting ring and the lower mounting ring.

[0016] By adopting the above technical solution, the dust cover prevents concrete block debris from falling into the inner side of the support spring, thus avoiding the debris affecting the normal operation of the support spring. At the same time, it also facilitates cleaning the debris of the concrete block on the anti-permeability mold demolding base.

[0017] Optionally, the lower base is further provided with a surrounding panel structure, the surrounding panel structure including a left surrounding panel connected to the left side edge of the lower base plate, a right surrounding panel connected to the right side edge of the lower base plate, a rear surrounding panel connected to the rear side edge of the lower base plate, and a front surrounding panel detachably connected between the left surrounding panel and the right surrounding panel.

[0018] By adopting the above technical solution, the enclosure structure reduces the amount of concrete test block debris falling onto the outside of the lower base, thus facilitating the cleaning of concrete debris and reducing the probability of cleaning difficulties caused by concrete debris falling onto the outside of the lower base. Furthermore, the front enclosure can be detachably installed on the left and right enclosures, allowing the front enclosure to be removed when cleaning the lower base, facilitating the cleaning of concrete debris inside the lower base.

[0019] Optionally, the left side panel has a left slot on the side facing the right side panel for insertion into one side of the front side panel; the right side panel has a right slot on the side facing the left side panel for insertion into the other side of the front side panel.

[0020] By adopting the above technical solution, a detachable structure for the front panel on the left and right panels is specifically disclosed.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] A demolding base for an anti-seepage mold, by setting a lower base and a support component, provides ideal support for the specimen sleeve during the process of the press extruding the concrete specimen from the specimen sleeve by the press, reducing the probability of the specimen sleeve tipping over and helping to improve the safety of the press extruding the concrete specimen from the specimen sleeve.

[0023] By setting up an elastic support component, the support plate always abuts against the bottom of the concrete specimen during the process of the press extruding the concrete specimen from the specimen sleeve, thus avoiding the concrete specimen directly impacting the lower base during demolding and causing debris to fly everywhere.

[0024] By setting a surrounding plate structure on the lower base, and having the front surrounding plate detachably installed on the left and right surrounding plates, most of the debris can fall into the lower base, reducing the probability of concrete specimen debris falling to the outside of the lower base, and making it easier to clean the debris of the concrete specimen inside the lower base.
