Description

Technical Field

[0001] This disclosure relates to, but is not limited to, the field of specimen preparation and curing, and more specifically, to a device for preparing and curing tensile specimens. Background Technology

[0002] When testing the tensile bond strength of products such as putty, mortar, and coatings (as per standards JG-T298-2010, GB / T28627, and GB / T 16777-2008), the sample is applied to the surface of a 70mm×70mm×40mm cement mortar block to form a specimen for testing. Current preparation processes either prepare each specimen individually or prepare multiple specimens simultaneously based on the number of molding frames. However, during preparation, the uneven thickness of the cement mortar block makes it impossible to maintain uniform specimen thickness when preparing multiple specimens. Furthermore, after preparation, multiple specimens and cement mortar blocks must be manually transported as a whole to the curing chamber, which can easily cause deformation and contamination of the specimens during transport, and also increases labor costs.

[0034] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be arbitrarily combined with each other.

[0035] Please combine them together Figures 1 to 5 and Figure 9 This disclosure provides a tensile specimen preparation and curing device. The device includes a cabinet 10, a control mechanism 20, and a pull-out assembly 30. The cabinet 10 has a receiving space and pull-out holes. The pull-out holes communicate with the receiving space. Support legs 11 are located at the bottom of the cabinet 10. In this embodiment, there are four pull-out holes, spaced vertically along one side of the cabinet 10. It can be understood that in other embodiments, the number of pull-out holes may be other values.

[0036] A control mechanism 20 is installed in the cabinet 10 and is configured to control the temperature and humidity of the storage space. The pull-out assembly 30 includes a body 31 and a cover 32. The body 31 is movably installed in the cabinet 10 and can be placed in the storage space through a pull-out hole, closing the hole to ensure the airtightness of the cabinet 10 and the relative stability of the temperature and humidity in the storage space. Furthermore, the body 31 can be removed from the storage space through the pull-out hole.

[0037] The pull-out assembly 30 has a main body 31 with multiple receiving grooves 100, each receiving groove 100 forming an opening 101 at the top of the main body 31. A cover 32 has multiple mold holes 200, each mold hole 200 providing space for sample application. The cover 32 covers the multiple openings 101, connecting the multiple mold holes 200 to the multiple receiving grooves 100 in a one-to-one correspondence. Each receiving groove 100 contains an elastic element 40 and a test block 50. The elastic element 40 is located on the main body 31 and abuts the test block 50 against the side of the cover 32 facing the receiving groove 100, thus closing the mold hole 200. In this embodiment, the test block 50 can be a cement mortar block with dimensions of 70mm × 70mm × 40mm.

[0038] During the test, the pull-out assembly 30 is removed from the receiving space through the pull-out hole. The pull-out assembly 30 can be completely separated from the cabinet 10 or partially connected, ensuring that each receiving slot 100 can be exposed outside the cabinet 10 after the cover 32 is removed. Then, the elastic element 40 and the test block 50 are placed into the receiving slot 100 in sequence. At this time, the elastic element 40 can support the test block 50 and partially expose it outside the slot opening 101, ensuring that the test block 50 can abut against the cover 32, and that the test block 50 can stably abut against the cover 32 when the sample is applied.

[0039] Next, the cover 32 is placed over the multiple slots 101, and each test block 50 is pressed into the receiving groove 100. At this time, the upper surface of each test block 50 is in the same plane, and the side of each mold hole 200 closest to the receiving groove 100 can be covered by the test block 50. The sample is applied to the mold hole 200 with a scraper, and after smoothing, the cover 32 is separated from the body 31. At this point, the specimen preparation is complete. There is no need to transport the specimen and test block 50 to the curing chamber for curing. The body 31 can be directly moved into the receiving space, the pull-out hole is closed, and the temperature and humidity in the receiving space are adjusted to the standard experimental conditions by the control mechanism 20, and the curing experiment can begin.

[0040] This embodiment includes a cabinet 10 with a receiving space and pull-out holes, a control mechanism 20 disposed on the cabinet 10, and a pull-out assembly 30. The control mechanism 20 controls the temperature and humidity of the receiving space, enabling curing of the specimens within the receiving space. This avoids the need to transport the specimens to a curing chamber after preparation, thus preventing deformation and contamination of the specimens during transportation and reducing labor costs. The pull-out assembly 30 includes a body 31 with multiple receiving slots 100 and a cover 32 with multiple mold holes 200. Each receiving slot 100 contains an elastic element 40 and a test block 50. The elastic element 40 is disposed on the body 31 and abuts the test block 50 against the side of the cover 32 facing the receiving slot 100, thus closing the mold hole 200. This ensures that the depth of the multiple mold holes 200 is uniform, resulting in a specimen with uniform thickness after sample application.

[0041] In the exemplary embodiments, please refer to Figure 3 , Figure 4 and Figure 9 The receiving groove 100 has a groove bottom 311 formed on the body 31 facing the groove opening 101. The groove bottom 311 is provided with multiple through holes 300 communicating with the receiving space and the receiving groove 100. The elastic element 40 is a helical spring. The through holes 300 and the helical spring allow air to smoothly enter the receiving groove 100, thereby ensuring that the temperature and humidity of the receiving groove 100 are closer to those of the receiving space, ensuring the reliability of specimen curing. One end of the elastic element 40 is located at the groove bottom 311, and the other end is located at the specimen block 50. Furthermore, in some embodiments, the elastic element 40 can also be an elastic structure made of a sheet or elastomer material.

[0042] In an exemplary embodiment, such as Figure 3 As shown, the groove bottom 311 includes two intersecting rods 3111 forming a cross shape. This facilitates the formation of through holes 300 and reduces the overall weight of the body 31, making it easier for the body 31 to move relative to the cabinet 10. In this embodiment, the two intersecting rods 3111 can form four through holes 300. The elastic member 40 can be coaxially arranged with the groove bottom 311 to ensure the stability of the groove bottom 311 supporting the elastic member 40.

[0043] In the exemplary embodiments, please refer to Figures 1 to 4 and Figure 9 The body 31 includes a plurality of first partitions 312 and a plurality of second partitions 313. The plurality of first partitions 312 extend along a first direction and are spaced apart along a second direction. The first direction is parallel to... Figure 3 The direction indicated by the middle arrow X. The second direction is parallel to... Figure 3 The direction indicated by the middle arrow Y.

[0044] Multiple second partitions 313 extend along a second direction and are spaced apart along a first direction. The two ends of each second partition 313 are connected to an adjacent first partition 312. The two ends of each rod 3111 are connected to at least one of the first partition 312 and the second partition 313, forming a receiving groove 100 together with the first and second partitions 312 and 313. This arrangement of the first and second partitions 312 and 313 ensures the structural stability of the receiving groove 100 and limits the movement of the test block 50, ensuring that the test block 50 stably abuts against the cover 32 under the drive of the elastic member 40. Furthermore, in some embodiments, the first and second partitions 312 and 313 can be detachably connected, allowing the size of the receiving groove 100 to be changed to accommodate test blocks 50 of different sizes.

[0045] In this embodiment, the body 31 further includes an end cap 314, which can be connected to one of the first partitions 312 located circumferentially around the body 31. The orthographic projection of the end cap 314 on the cabinet 10 can cover the pull-out hole, and the end cap 314 can close the pull-out hole to ensure the airtightness of the accommodating space. A handle 315 is also provided on the side of the end cap 314 away from the accommodating space to facilitate driving the body 31 to move relative to the cabinet 10.

[0046] In the exemplary embodiments, please refer to Figure 4 and Figure 9 The outer circumferential surface of the test block 50 is fitted with at least one of the first partition 312 and the second partition 313, which reduces the obstruction of the test block 50 to air, allowing air to smoothly enter and exit the receiving tank 100. This further ensures that the temperature and humidity of the receiving tank 100 are closer to those of the receiving space, thus ensuring the reliability of the specimen curing.

[0047] In the exemplary embodiments, please refer to Figure 3 , Figure 4 and Figure 9 The cabinet 10 is equipped with slide rails that are housed within the receiving space. The main body 31 is provided with a sliding part 316 that slides and engages with the slide rails. Through the cooperation of the slide rails and the sliding part 316, the main body 31 can smoothly enter and exit the receiving space, and the slide rails provide support for the main body 31, ensuring its stable placement within the receiving space. In this embodiment, each main body 31 has slide rails on both sides, and a sliding part 316 that slides and engages with the slide rails. The sliding part 316 has an inverted L-shaped cross-section, a simple structure, and can ensure sufficient connection area with both the main body 31 and the slide rails, thus ensuring the sliding stability between the main body 31 and the cabinet 10. It can be understood that in other embodiments, the cabinet 10 can also be equipped with a shelf, on which the main body 31 can be placed, placing the main body 31 within the receiving space.

[0048] In the exemplary embodiments, please refer to Figures 5 to 9 The cover 32 includes a cover plate 321 and multiple movable parts 322. The cover plate 321 is provided with multiple mounting holes 400, which are connected to multiple slots 101 in a one-to-one correspondence. The multiple movable parts 322 are movably mounted in the multiple mounting holes 400 in a one-to-one correspondence. The mold hole 200 is located in the movable part 322. In this way, by changing different types of movable parts 322, the size of the mold hole 200 can be changed, thereby obtaining specimens of different sizes. The size can be the thickness of the specimen, or the length and width of the specimen. For example, the thickness can be one of 1 mm, 2 mm, and 5 mm. The thickness of the mold hole 200 of the multiple movable parts 322 can be the same or different, and can be replaced with different thicknesses according to standard requirements to meet the preparation process of multiple standards. In this embodiment, the mounting hole 400 can be a stepped hole, and the movable part 322 can be positioned and connected to the mounting hole 400 to ensure the positional stability of the movable part 322 during the application of the sample. Furthermore, it can prevent the movable part 322 from falling into the slot 101 through the mounting hole 400. During the test, separating the cover 32 from the body 31 can be done by first separating the movable part 322 from the cover plate 321, and then separating the cover plate 321 from the body 31.

[0049] In the exemplary embodiments, please refer to Figures 6 to 8 The movable part 322 is provided with a lifting part 323, which is located on the outer circumferential side of the movable part 322 to facilitate the disassembly and assembly of the movable part 322 and the cover plate 321. The lifting part 323 is rod-shaped and located at the corner of the movable part 322, as far away as possible from the mold hole 200 to avoid interfering with the movement of the scraper.

[0050] In the exemplary embodiments, please refer to Figures 7 to 9 At least one set of clamping plates is provided on the outer circumferential side of the cover plate 321. Each set of clamping plates has two clamping plates 324, which are located on opposite sides of the cover plate 321 and are folded towards the body 31 to clamp the body 31. In this way, the clamping plates 324 facilitate the positioning of the cover 32 and the body 31, preventing the cover 32 from moving relative to the body 31 and affecting the molding of the specimen.

[0051] In the exemplary embodiments, please refer to Figure 1 and Figure 2 The control mechanism 20 includes a control panel 21, a display screen 22, a temperature control component, and a humidity control component. Signals can be transmitted between the control panel 21, the display screen 22, the temperature control component, and the humidity control component via conventional wired or wireless means. The control mechanism 20 can be connected to a power source via an external cable 23.

[0052] Control panel 21, temperature control component, and humidity control component are located in cabinet 10. Control panel 21 is configured to control the temperature control component and humidity control component to turn on and off, thereby controlling the temperature and humidity of the storage space. Display screen 22 is located in cabinet 10 and is configured to display the temperature and humidity information of the storage space, so as to facilitate real-time monitoring of the temperature and humidity information of the storage space.

[0053] The temperature control components may include an air pump, an air heater, an air cooler, and a temperature sensor. The cabinet 10 is provided with an air vent 500. The air pump is located in the cabinet 10 and connected to the air vent 500. The air pump can be connected to the containment space via the air heater and the air cooler, respectively. The control panel 21 controls, but is not limited to, controlling the forward and reverse rotation of the air pump, controlling the on / off state of the air heater and air cooler, controlling the connection or disconnection of the air pump with the air heater, and controlling the connection or disconnection of the air pump with the air cooler. Controlling the air pump to rotate forward introduces air from the outside into the containment space. Controlling the air pump to rotate in reverse discharges air from the containment space into the cabinet 10. The air heater heats the air. The air cooler cools the air. The temperature sensor is located in the cabinet 10 and housed within the containment space, and can monitor the temperature of the containment space. The control panel 21 can control the air pump, air heater, and air cooler based on the temperature information monitored by the temperature sensor, adjusting the air temperature within the containment space to the standard experimental conditions.

[0054] The humidity control assembly may include a water tank 60, a sprayer, and a humidity sensor. The water tank 60 is externally mounted on the cabinet 10 for easy water addition. The sprayer is located on the cabinet 10 and housed within a storage space. The sprayer includes a pump body and a nozzle. The nozzle communicates with the water tank 60 via the pump body. The humidity sensor, located on the cabinet 10 and housed within the storage space, monitors the humidity of the storage space. The control panel 21 controls the pump body based on the humidity information monitored by the humidity sensor, adjusting the water flow rate into the storage space. Water can be sprayed into the storage space through the nozzle, regulating the air humidity within the storage space to the standard experimental conditions. Alternatively, in other embodiments, the control mechanism 20 may be a conventional temperature and humidity control mechanism 20 for other curing chambers.
