Description

Technical Field

[0001] This utility model relates to the field of heat resistance testing technology for waterproof coatings, and in particular to a specimen suspension device for testing the heat resistance of waterproof coatings. Background Technology

[0002] The heat resistance of building waterproofing coatings is a core performance indicator that determines their long-term service life in high-temperature environments, and is related to the durability and reliability of building waterproofing projects. Before being applied to actual projects, different building waterproofing coatings must be tested to ensure that their heat resistance meets the requirements, so as to effectively resist the effects of heat aging, temperature difference deformation and other factors during the building's service life, thereby achieving a long-term reliable waterproofing effect.

[0003] Currently, waterproof coating specimens are mainly suspended vertically on the partition of the oven using hooks or clips, which can only test the temperature resistance of the specimens at a vertical angle. Although there are some devices for suspending specimens, such as the suspension device for determining the heat resistance of asphalt waterproof membrane disclosed in Chinese patent CN214374422U, it is also used for vertical suspension and cannot simulate the multi-angle stress of specimens in building waterproofing projects, nor can it reflect the deformation behavior under complex stress environments.

[0004] Therefore, there is a need to develop a multi-angle suspension device for testing the durability and reliability of waterproof coatings under different angle conditions. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a specimen suspension device for testing the heat resistance of waterproof coatings, which enables multi-angle suspension.

[0006] This utility model provides a specimen suspension device for testing the heat resistance of waterproof coatings, comprising:

[0007] Horizontal base;

[0008] A vertical hanger is vertically mounted on the horizontal base and is used to vertically suspend the specimen.

[0009] An inclined support assembly is inclinedly disposed between the horizontal base and the vertical hanger for inclined placement of the specimen, and at least one end of the inclined support assembly is hinged to a sliding block;

[0010] The horizontal base and / or the vertical bracket are respectively provided with a sliding groove that slides with the sliding block. The sliding groove on the horizontal base extends horizontally and is perpendicular to the plane of the vertical bracket. The sliding groove on the vertical bracket extends vertically.

[0011] The sliding block slides along the groove to adjust the position of the end of the support rod on the horizontal base and / or the vertical bracket, thereby adjusting the angle between the inclined support assembly and the horizontal base.

[0012] In some embodiments of this application, the inclined support assembly includes:

[0013] There are two supporting diagonal rods, symmetrically arranged on both sides of the horizontal base, and at least one end of the supporting diagonal rod is hinged to the sliding block;

[0014] A support crossbar is disposed between the two support diagonal bars, and the support crossbar is used to place the specimen at an angle.

[0015] In some embodiments of this application, the supporting diagonal rod is a telescopic rod-shaped structure, one end of the supporting diagonal rod is hinged to the horizontal base or the vertical bracket, and the other end is hinged to the sliding block. The length of the supporting diagonal rod extends or shortens as the position of the sliding block changes.

[0016] In some embodiments of this application, a plurality of angle adjustment holes are distributed along the length of the bottom surface of the slide, and a positioning hole is provided on the sliding block;

[0017] The suspension device further includes a positioning element that cooperates with the positioning hole and one of the angle adjustment holes to fix the sliding block at different positions in the slide groove.

[0018] In some embodiments of this application, the inclined support assembly further includes a baffle fixed between the two supporting inclined rods and located below the supporting inclined rods. The plane of the baffle is perpendicular to the plane of the two supporting inclined rods. The baffle is used to limit the lower end of the specimen to prevent the specimen placed on the supporting crossbar from slipping.

[0019] In some embodiments of this application, there are at least two support crossbars to provide stable support for the specimen.

[0020] In some embodiments of this application, the vertical bracket includes two uprights and a horizontal hanging rod disposed between the two uprights. The uprights are vertically and symmetrically fixed on both sides of the horizontal base, and the horizontal hanging rod is located above the horizontal base. The specimen is vertically suspended on the horizontal hanging rod.

[0021] In some embodiments of this application, the upper end of the supporting diagonal rod is slidably connected to or hinged to the upright rod.

[0022] Based on the above scheme, the specimen suspension device for the heat resistance test of waterproof coatings in this application has a horizontal hanging rod that vertically suspends the specimen, and a support crossbar that tilts the specimen. The tilt angle of the specimen is the same as the tilt angle of the support crossbar. This suspension device can simultaneously suspend or tilt multiple specimens vertically or tilt them to test the flow, slippage and interface peeling behavior of waterproof coatings under resistance to self-weight or oblique force, thereby improving the test efficiency and operation convenience of heat resistance.

[0023] By adjusting the position of the end of the support rod and thus the tilt angle of the support rod, the performance of the specimen at different tilt angles can be tested. Attached Figure Description

[0040] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0041] In the description of this utility model, it should be understood that the terms "center", "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0043] Currently, when conducting heat resistance tests on waterproof coatings, the main method is to vertically suspend the specimens on the partitions inside the oven using hooks or clips, or to use some simple specimen suspension devices. However, these methods can only achieve vertical suspension and can only test the temperature resistance performance of the specimens at a vertical angle. They cannot simulate the multi-angle stress on the specimens in building waterproofing projects, nor can they reflect the deformation behavior under complex stress environments.

[0044] To enable testing the performance of waterproof coatings under multi-angle suspension, embodiments of this application provide a specimen suspension device for testing the heat resistance of waterproof coatings, such as... Figure 1As shown, the device includes a horizontal base 10, a vertical hanger 20 vertically mounted on the horizontal base 10, and an inclined support assembly 30 inclined between the horizontal base 10 and the vertical hanger 20. The vertical hanger 20 is used to suspend the specimen vertically, and the inclined support assembly 30 is used to place the specimen at an angle. The two ends of the inclined support assembly 30 are slidably connected to the horizontal base 10 and / or the vertical hanger 20, so that the tilt angle of the inclined support assembly 30 relative to the horizontal base 10 can be adjusted to test the performance of the specimen at different tilt angles.

[0045] In some embodiments, such as Figure 2 As shown, the inclined support assembly 30 includes two symmetrically arranged inclined support rods 31 on both sides of the horizontal base 10. The two ends of the inclined support rods 31 are slidably connected to the horizontal base 10 and / or the vertical bracket 20, respectively. The ends of the inclined support rods 31 slide along the horizontal base 10 and / or the vertical bracket 20 to adjust the position of the ends of the inclined support rods 31 on the horizontal base 10 and / or the vertical bracket 20, so that the tilt angle of the inclined support rods 31 relative to the horizontal base 10 changes.

[0046] The inclined support assembly 30 also includes a support crossbar 32 disposed between two support crossbars 31. The two ends of the support crossbar 32 are respectively fixed on the two support crossbars 31. When the specimen is placed on the support crossbar 32, the specimen is parallel to the support crossbar 31, that is, the tilt angle of the specimen is the same as the tilt angle of the support crossbar 31. Adjusting the tilt angle of the support crossbar 31 relative to the horizontal base 10 can test the performance of the specimen at different tilt angles.

[0047] In some embodiments, the horizontal base 10 is a rectangular frame structure, including two oppositely arranged long sidewalls 11 and a short sidewall 12 connected between the two long sidewalls 11; the lower end of the support rod 31 is connected to the long sidewalls 11, and the vertical bracket 20 is also connected to the long sidewalls 11. There is enough space on the long sidewalls 11 to allow the lower end of the support rod 31 to move back and forth, and the angle between the support rod 31 and the long sidewalls 11 can be adjusted, that is, the tilt angle of the support rod 31 relative to the horizontal base 10 can be adjusted within a certain range.

[0048] In some embodiments, the tilt angle of the support strut 31 relative to the horizontal base 10 is adjustable between 30° and 60°.

[0049] In some embodiments, the vertical hanger 20 includes two uprights 21 and a horizontal hanger 22 connected between the two uprights. The uprights 21 are vertically and symmetrically fixed at the middle position of the two long sidewalls 11 of the horizontal base 10. The horizontal hanger 22 is parallel to the short sidewall 12 and is located above the plane of the horizontal base. The specimen is vertically suspended on the horizontal hanger 22 using clips or hooks.

[0050] The upper end of the support diagonal rod 31 is connected to the upright rod 21. The support diagonal rod 31, the upright rod 21 and the long frame 11 form a right-angled triangle structure. The end of the support diagonal rod 31 moves along the upright rod 21 and / or the long frame 11, so that the included angle between the support diagonal rod 31 and the long frame 11 changes, that is, the tilt angle of the support diagonal rod 31 relative to the horizontal base 10 changes.

[0051] In some embodiments, such as Figure 2 As shown, the upper end of the support rod 31 is hinged to the upright rod 21 through the first pin 211, and the lower end of the support rod 31 is slidably connected to the long frame 11. The lower end of the support rod 31 slides left and right on the long frame 11, and its upper end rotates relative to the upright rod 21.

[0052] It should be noted that in this embodiment, the support rod 31 is a telescopic rod structure. When the lower end of the support rod 31 slides along the long frame 11 away from the upright 21, that is, moves to the left end of the long frame 11, the support rod 31 extends and the angle between the support rod 31 and the long frame 11 decreases. When the lower end of the support rod 31 slides along the long frame 11 towards the upright 21, that is, moves to the right side of the long frame 11, the support rod 31 retracts and the angle between the support rod 31 and the long frame 11 increases.

[0053] The telescopic rod structure is a common structure in existing technology, and will not be described in detail here.

[0054] In some embodiments, in order to enable the support rod 31 to slide on the long frame 11, each long frame 11 is provided with a first groove 111 extending along its length direction. The lower end of the support rod 31 is hinged to a first sliding block 311 arranged in the horizontal direction. The first sliding block 311 is placed in the first groove 111 and moves along the first groove 111 to adjust the position of the lower end of the support rod 31 on the long frame 11.

[0055] In some embodiments, such as Figure 3 As shown, three first angle adjustment holes 112 are distributed along the length direction on the bottom surface of the first slide groove 111. The first sliding block 311 has a vertical first positioning hole 312. The first positioning hole 312 is a threaded through hole, and the first angle adjustment hole 112 is a threaded hole. The suspension device includes a positioning element, which is a bolt (not shown in the figure). The bolt passes through the first positioning hole 312 and the first angle adjustment hole 112 in sequence to fix the first sliding block 311 at different positions in the first slide groove.

[0056] Specifically, when the first positioning hole 312 is coaxially engaged with the first angle adjustment hole 112 at the leftmost end of the long frame 11, the angle between the support rod 31 and the long frame 11 is at least 30°; when the first positioning hole 312 is coaxially engaged with the first angle adjustment hole 112 at the middle position, the angle between the support rod 31 and the long frame 11 is 45°; when the first positioning hole 312 is coaxially engaged with the first angle adjustment hole 112 at the rightmost end of the upright 21, the angle between the support rod 31 and the long frame 11 is at most 60°. This allows for testing the performance of the waterproof coating when the specimen is tilted at 30°, 45°, and 60°.

[0057] It should be noted that as the angle between the supporting diagonal rod 31 and the long frame 11 changes, the supporting diagonal rod 31 also rotates relative to the first sliding block 311. The hinge structure between the end of the supporting diagonal rod 31 and the first sliding block 311 is as follows: Figure 4 As shown, the two vertical side plates 3111 of the first sliding block 311, which slides in contact with the two side walls of the first slide groove 111, have hinged mounting plates 3112 extending along their length. The hinged mounting plates 3112 have symmetrical mounting holes 3113, and the ends of the supporting inclined rod 31 have corresponding pin holes (not shown in the figure). The third pin 3114 passes through the pin hole of the supporting inclined rod 31, and its two ends are located in the two mounting holes 3113 respectively. When the first sliding block 311 slides along the first slide groove 111, the lower end of the supporting inclined rod 31 rotates around the third pin 3114, causing the angle between the supporting inclined rod 31 and the long frame 11 to change.

[0058] In some embodiments, such as Figure 5 As shown, the lower end of the support rod 31 is hinged to the long frame 11 via the second pin 113, and the upper end of the support rod 31 is slidably connected to the upright 21. The upper end of the support rod 31 slides up and down along the upright 21, and its lower end rotates relative to the long frame 11 to adjust the angle between the support rod 31 and the long frame 11.

[0059] In some embodiments, in order to enable the supporting diagonal rod 31 to slide up and down on the upright rod 21, such as Figure 6 As shown, the upright 21 has a second sliding groove 212 extending along its height direction. The upper end of the supporting diagonal rod 31 is hinged to a second sliding block 313. The second sliding block 313 is placed in the second sliding groove 212 and moves up and down along the second sliding groove 212 to adjust the position of the upper end of the supporting diagonal rod 31 on the upright 21.

[0060] In some embodiments, such as Figure 6As shown, three second angle adjustment holes 213 are distributed along the height direction on the bottom surface of the second slide groove 212. The second sliding block 313 has a second positioning hole 314, which is also a threaded through hole. The second angle adjustment hole 213 is a threaded hole. Bolts (not shown in the figure) pass through the second positioning hole 314 and the second angle adjustment hole 213 in sequence to fix the second sliding block 313 at different positions in the second slide groove 212.

[0061] Specifically, when the second positioning hole 314 is coaxially engaged with the uppermost second angle adjustment hole 213, the minimum angle between the support rod 31 and the long frame 11 is 30°; when the second positioning hole 314 is coaxially engaged with the middle second angle adjustment hole 213, the angle between the support rod 31 and the long frame 11 is 45°; when the second positioning hole 314 is coaxially engaged with the lowermost second angle adjustment hole 213, the maximum angle between the support rod 31 and the long frame 11 is 60°. This can also be used to test the performance of the waterproof coating when the specimen is tilted at 30°, 45°, and 60°.

[0062] It should be noted that the hinge structure between the upper end of the support rod 31 and the second sliding block 313 is... Figure 4 The lower end of the supporting inclined rod 31 shown is the same as the hinge structure of the first sliding block 311, and will not be described again here. When the second sliding block 313 slides along the second sliding groove 212, the upper end of the supporting inclined rod 31 rotates around the first pin, causing the angle between the supporting inclined rod 31 and the upright rod 21 to change.

[0063] In some embodiments, when the supporting diagonal rod 31 is a rod-shaped structure of fixed length, the lower end of the supporting diagonal rod 31 and the long frame 11 can be adopted as follows: Figure 3 The structure shown has a first groove 111 extending along its length on each long frame 11. A horizontally positioned first sliding block 311 is hinged to the lower end of the supporting diagonal rod 31. Three first angle adjustment holes 112 are distributed along the length of the bottom surface of the first groove 111. A vertical first positioning hole 312 is formed on the first sliding block 311. The first positioning hole 312 is a threaded through hole, and the first angle adjustment hole 112 is a threaded hole. The upper end of the supporting diagonal rod 31 and the upright rod 21 are constructed as shown in the diagram. Figure 6 The structure shown has a second sliding groove 212 extending along its height direction on the upright 21, a second sliding block 313 hinged to the upper end of the supporting diagonal rod 31, three second angle adjustment holes 213 distributed along its height direction on the bottom surface of the second sliding groove 212, and a second positioning hole 314 on the second sliding block 313.

[0064] It should be noted that at this time, the first angle adjustment hole 112 corresponds one-to-one with the second angle adjustment hole 213. The leftmost first angle adjustment hole 112 corresponds to the bottommost second angle adjustment hole 213. At this time, the angle between the support rod 31 and the long frame 11 is 30°. The middle first angle adjustment hole 112 corresponds to the middle second angle adjustment hole 213. At this time, the angle between the support rod 31 and the long frame 11 is 45°. The rightmost first angle adjustment hole 112 corresponds to the topmost second angle adjustment hole 213. At this time, the angle between the support rod 31 and the long frame 11 is 60°.

[0065] When fixing the angle of the support rod 31, it is only necessary to fix one of the following sets: the first positioning hole 312 and the first angle adjustment hole 112, or the second positioning hole 314 and the second angle adjustment hole 213.

[0066] The hinge structure between the lower end of the supporting diagonal rod 31 and the first sliding block 311, and the hinge structure between the upper end of the supporting diagonal rod 31 and the second sliding block 313 are both as follows: Figure 4 The structure shown.

[0067] In some embodiments, when the supporting diagonal rod 31 is a rod-shaped structure of fixed length, in order to adjust the angle between the supporting diagonal rod 31 and the long frame 11, the lower ends of the long frame 11 and the supporting diagonal rod 31 are configured as follows: Figure 3 The structure shown, the structure of the upper end of the upright 21 and the supporting diagonal 31 is as follows Figure 7 As shown, the upright 21 has a second sliding groove 212 extending along its height direction, and the upper end of the supporting diagonal rod 31 is hinged to a second sliding block 313. The bottom surface of the second sliding groove 212 is a smooth surface, and no second angle adjustment hole 213 is provided. No second positioning hole is provided on the second sliding block 313 either. When the first sliding block 311 slides in the first sliding groove 111, the second sliding block 313 slides along the second sliding groove 212 accordingly. When the bolt fixes the first sliding block 311 to one of the first angle adjustment holes 112, the position of the second sliding block 313 in the second sliding groove 212 is also fixed.

[0068] In some embodiments, when the support rod 31 is a rod-shaped structure of fixed length, the first groove 111 on the long frame 11 is a smooth structure, and the second groove 212 on the upright 21 has a second angle adjustment hole 213. The tilt angle of the support rod 31 can be fixed by fixing the second positioning hole 314 and the second angle adjustment hole 213 with bolts.

[0069] It should be noted that, in the above embodiments, the hinge structure between the lower end of the supporting diagonal rod 31 and the first sliding block 311, and the hinge structure between the upper end of the supporting diagonal rod 31 and the second sliding block 313 are also as follows. Figure 4 The structure shown.

[0070] In some embodiments, the inclined support assembly 30 further includes a baffle 33, which is fixed between two supporting inclined rods 31, and a supporting crossbar 32 is above the baffle 33. The plane of the baffle 33 is perpendicular to the plane of the two supporting inclined rods 31.

[0071] like Figure 2 As shown, the baffle 33 is fixed below the two supporting inclined rods 31. The specimen is placed on the supporting horizontal rod 32. The length direction of the specimen is parallel to the length direction of the supporting inclined rod 31. The supporting horizontal rod 32 supports the specimen. The lower end of the specimen abuts against the upper surface of the baffle 33 to prevent the lower end of the specimen from slipping off the supporting horizontal rod 32.

[0072] In some embodiments, the suspension device can simultaneously suspend the specimen vertically and place it at an angle. In this case, the upper end of the support rod 31 is hinged to the upright rod 21, and the lower end is slidably connected to the long frame 11. The angle of the support rod 31 can be adjusted by adjusting the position of the lower end of the support rod 31 on the long frame 11. The distance between the horizontal hanging rod 22 and the baffle 33 is the same as the length of the specimen, so that the height of the inclined specimen is consistent with that of the vertically suspended specimen.

[0073] It should be noted that the distance between the horizontal hanging rod 22 and the baffle 33 is the same as the length of the support diagonal rod 31 located between the baffle 33 and the first pin 211.

[0074] In some embodiments, there may be two horizontal hanging rods 22, arranged vertically, with the distance between the two horizontal hanging rods 22 being the length of the specimen. When testing the performance of the waterproof coating at a vertical angle, one of the horizontal hanging rods 22 can be selected for vertical suspension.

[0075] Based on the above scheme, the specimen suspension device for the heat resistance test of waterproof coatings in this application has a horizontal hanging rod that vertically suspends the specimen, and a support crossbar that tilts the specimen. The tilt angle of the specimen is the same as the tilt angle of the support crossbar. This suspension device can simultaneously suspend multiple specimens vertically or tilt them to test the flow, slippage and interface peeling behavior of waterproof coatings under resistance to self-weight or oblique force, thereby improving the test efficiency and operation convenience of heat resistance.

[0076] By adjusting the position of the end of the support rod and thus the tilt angle of the support rod, the performance of the specimen at different tilt angles can be tested.

[0077] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0078] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
