[0002] Vitrified microsphere insulation mortar is a single-component dry-mixed high-performance inorganic wall insulation material composed of vitrified microspheres, cement and admixtures. It can be widely used in wall insulation projects of new and old buildings to effectively improve the indoor thermal environment.

[0003] After the vitrified microsphere insulation mortar is configured, during the hardening process, the volume of the mortar hydration product is smaller than the original volume, and the free water evaporates and the gel loses water and shrinks. When the mortar hardens in water, due to the presence of water, its volume remains unchanged, and it may even expand slightly, but the expansion value is much smaller than the contraction value, and generally has no bad effect, while contraction often causes mortar cracks.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0032] See also Figure 1 to Figure 8 In an embodiment of the present invention, a vitrified microsphere insulation mortar shrinkage detection device under different environments includes: a frame structure, a driving mechanism, a second slider 14, a fixed sleeve 18, an energy storage structure and a trigger assembly, so that during measurement, the detection wheel 15 can maintain a predetermined inclination angle, and when the mortar column makes a circular motion, the detection wheel 15 can make a spiral motion on the mortar column, thereby performing a fine measurement of the circumferential surface of the mortar column.

[0033] The details are as follows: the frame structure includes a base 1 and two groups of side frames 2, and a support plate 13 is provided at one end of the side frame 2 away from the base 1. A group of No. 1 rollers 4 and two groups of No. 2 rollers 5 are provided on the side frame 2. The No. 1 rollers 4 cooperate with the No. 2 rollers 5 to clamp and support the end of the mortar column, and the No. 1 rollers 4 are connected to the output shaft of the No. 1 motor 3 provided on the side frame 2; the driving mechanism is provided on the side frame 2 and connected to the two groups of No. 2 rollers 5, and the driving mechanism can drive the two groups of No. 2 rollers 5 to move toward the No. 1 roller 4; the driving mechanism includes a follower arm 6 provided on the frame structure, and two No. 1 slide grooves 601 are symmetrically provided on the follower arm 6, and a No. 1 slider 7 rotatably connected to the two groups of No. 2 rollers 5 is slidably installed in the No. 1 slide groove 601. An internal thread is formed in the No. 1 slider 7, and a bidirectional screw rod 8 rotatably installed along the length direction of the follower arm 6 cooperates with the internal thread, and the bidirectional screw rod 8 is connected to the No. 2 motor 10 arranged on the follower arm 6, wherein a sliding connection part 602 is provided on one side of the follower arm 6, and the sliding connection part 602 is slidably connected to a guide member 9 arranged on the frame structure; the driving mechanism also includes a guide kit connecting the No. 1 slider 7 and the frame structure, the guide kit includes a guide wheel 12 rotatably connected to the No. 1 slider 7 and a guide member 11 connected to the frame structure, an inclined guide surface 1101 is formed on the guide member 11, and the guide wheel 12 can roll on the inclined guide surface 1101, wherein the acute angle between the inclined guide surface 1101 and the horizontal plane is 60°.

[0034] In the initial state, the No. 1 roller 4 and the two groups of No. 2 rollers 5 are in an equilateral triangle state, and the distance between them is the largest. At this time, the hardened mortar column is placed between the No. 1 roller 4 and the two groups of No. 2 rollers 5, and the No. 2 motor 10 is started. The output shaft of the No. 2 motor 10 will drive the bidirectional screw 8 to rotate, so that the two No. 1 sliders 7 can move closer to each other, and at the same time drive the two guide wheels 12 to move closer to each other, and the guide wheels 12 move along the inclined guide surface 1101, so that the two groups of guide wheels 12 can be inclined upward at 60 degrees. Movement, at this time, the No. 1 roller 4 and the No. 2 roller 5 can always maintain the state of forming an equilateral triangle, so as to lift the mortar column, and when the No. 1 roller 4 and the No. 2 roller 5 are in contact with the circumferential surface of the end of the mortar column, the three are roughly on the trisection line of the circumferential surface of the mortar column, so that the mortar column has better stability between the No. 1 roller 4 and the No. 2 roller 5, and for mortar columns of different radii, the No. 1 roller 4 and the No. 2 roller 5 can achieve stable clamping and supporting, so that the mortar columns that the device can detect are more diversified.

[0035] Through the above arrangement, when the two groups of No. 2 rollers 5 move, they can always be in an equilateral triangle state with the No. 1 roller 4, so that when the three are in contact with the mortar column, they can be respectively located on the trisection lines of the mortar column. On the one hand, the stability of the mortar column when being clamped and supported can be improved, and on the other hand, mortar columns of different diameters can be clamped and supported, so that the mortar columns that can be detected by the device are more diversified, thereby improving the applicability of the device.

[0036] It should be noted that the above-mentioned mortar column should be cast using a cylindrical mold so that the hardened mortar column can be cylindrical, which is convenient for detection. In order to detect the influence of different environmental factors on the shrinkage of mortar, it is necessary to place the cylindrical mold in different environments for casting and test the mortar after hardening, so as to simulate the influence of different environmental factors on the shrinkage of mortar.

[0037] At this stage, the No. 1 roller 4 and the two No. 2 rollers 5 can be used to roughly measure the diameter of the mortar column. The ratio of the measurement result to the inner diameter of the casting mold is the shrinkage ratio of the mortar in this environment. This result plays a certain reference role in the shrinkage detection of the mortar.

[0038] It is worth noting that rubber sleeves are provided on the circumferential surfaces of the No. 1 roller 4 and the No. 2 roller 5 to increase the friction between the No. 1 roller 4, the No. 2 roller 5 and the mortar column, so that when the No. 1 motor 3 is working, the mortar column can be driven to rotate by driving the No. 1 roller 4 to rotate, and the provision of the rubber sleeves prevents the No. 1 roller 4, the No. 2 roller 5 from acting on the mortar column and destroying the structure of the mortar column.

[0039] See also Figure 5~Figure 8The second slider 14 is slidably mounted on the support plate 13. Specifically, a second slide groove 1301 is provided on the support plate 13. The second slider 14 is slidably mounted in the second slide groove 1301. Specifically, a "U"-shaped hysteresis portion is formed on both sides of the second slider 14. The "U"-shaped hysteresis portion is slidably fitted with the side wall of the second slide groove 1301 along its length direction, so that the second slider 14 can slide along the length direction of the second slide groove 1301. A connecting shaft 16 is slidably provided in the second slider 14. A detection wheel 15 is rotatably mounted on one end of the connecting shaft 16. , the connecting shaft 16 is also sleeved with a No. 1 columnar spring 17, one end of the No. 1 columnar spring 17 is connected to the No. 2 slider 14, and the other end is connected to the end of the connecting shaft 16, the connecting shaft 16 is slidably arranged in the No. 2 slider 14, and the detection wheel 15 is rotatably installed at one end of the connecting shaft 16, and the connecting shaft 16 is also sleeved with a No. 1 columnar spring 17, one end of the No. 1 columnar spring 17 is connected to the No. 2 slider 14, and the other end is connected to the end of the connecting shaft 16; the fixed sleeve 18 is fixedly connected to the No. 2 slider 14 and connected to the connecting shaft 16 is coaxial, a guide groove is formed on the side wall of the fixed sleeve 18, and the guide groove includes two arc grooves 1801 symmetrically arranged on the fixed sleeve 18, the two arc grooves 1801 are connected, and a lower convex portion 1802 is formed at the connection between the two arc grooves 1801; the energy storage structure is arranged between the connecting shaft 16 and the fixed sleeve 18, and a convex rod 1902 that can slide in the guide groove is formed on the energy storage structure, and the energy storage structure cooperates with the guide groove to enable the convex rod 1902 to maintain a state at the end of the guide groove, and enable The rotation axis of the detection wheel 15 is at a predetermined angle to the central axis of the mortar column; the energy storage structure includes a sliding fitting 19 slidably mounted on the connecting shaft 16 and a convex ring 1803 arranged in the fixed sleeve 18, and a No. 2 columnar spring 20 mounted on the connecting shaft 16 connects the sliding fitting 19 and the convex ring 1803, and the convex rod 1902 is installed on the sliding fitting 19; a limiting block 1901 is formed on the inner wall of the sliding fitting 19, and the limiting block 1901 is slidably matched with a limiting groove 1601 arranged on the connecting shaft 16.

[0040] In the initial state, the height of the detection wheel 15 is lower than that of the No. 1 roller 4, so that when the mortar column is clamped and supported, when the mortar column abuts against the No. 1 roller 4, the detection wheel 15 can be lifted upward and the No. 1 column spring 17 can be compressed, so that when a certain area of ​​the mortar column shrinks to a large extent, the detection wheel 15 can also complete the detection.

[0041] Furthermore, in the initial state, the protruding rod 1902 is at the end of one of the arc grooves 1801, and the No. 2 column spring 20 is in a compressed state. The reaction force of the No. 2 column spring 20 can keep the sliding fitting 19 in its current state, and the sliding fitting 19 can keep the connecting shaft 16 in its current state through the limit block 1901 and the limit groove 1601, so that the rotation axis of the detection wheel 15 can be at a predetermined angle with the central axis of the mortar column. At this time, when the mortar column rotates, the detection wheel 15 can move in the length direction of the mortar column and form a spiral motion trajectory on the mortar column to detect the shrinkage of the entire circumferential surface of the mortar column.

[0042] It should be noted that a displacement sensor (not shown in the figure) is connected to the connecting shaft 16. The displacement sensor can detect the position change of the connecting shaft 16 when the detection wheel 15 makes a spiral motion on the mortar column, thereby accurately measuring the circumferential surface of the mortar column to measure the shrinkage ratio of the local position of the mortar column, thereby improving the accurate detection of the mortar shrinkage ratio.

[0043] Through the above arrangement, the detection wheel 15 can maintain a predetermined tilt angle during measurement, and when the mortar column makes a circular motion, the detection wheel 15 can make a spiral motion on the mortar column, thereby performing a fine measurement of the circumferential surface of the mortar column.

[0044] Among them, the change signal detected by the displacement sensor is generally relatively gentle. If there is a large deviation, it indicates that the mortar column at that position has a bulge or crack caused by the shrinkage of the mortar column.

[0045] See also Figure 5 , Figure 6 , Figure 8 , the trigger assembly is arranged on the support plate 13, and the trigger assembly can act on the connecting shaft 16 when the detection wheel 15 rolls to the end of the mortar column, so that the protruding rod 1902 is switched from one end of the guide groove to the other end; the trigger assembly includes a horizontally arranged lifting frame 22, and the lifting frame 22 is connected to the frame structure through a telescopic rod, and the lifting frame 22 is connected to the electric telescopic rod 24 arranged on the frame structure, wherein the telescopic rod includes a guide shaft 25 fixedly connected to the lifting frame 22 and and a guide sleeve 26 connected to the frame structure, the guide shaft 25 slidingly fits with the guide sleeve 26; the trigger assembly also includes two sets of vertical shafts 23 symmetrically mounted on the lifting frame 22, a convex shaft 23 is provided on the vertical shaft 23, a reversing member 21 coaxially fixedly connected to the connecting shaft 16 can cooperate with the convex shaft 2301 to rotate the connecting shaft 16, and a plurality of arc surfaces 2101 are provided on one end of the reversing member 21 facing the vertical shaft 23, and the arc surface 2101 is adapted to the convex shaft 2301.

[0046] When the detection wheel 15 moves to the end of the mortar column, the mortar column can be disassembled and a new mortar column to be detected can be installed. At this time, after the new mortar column is installed, the electric telescopic rod 24 will perform the driving action and drive the vertical shaft 23 to move downward through the lifting frame 22. When the convex shaft 2301 abuts against the arc surface 2101, the reversing member 21 is driven to rotate. At the same time, the reversing member 21 will drive the connecting shaft 16 to rotate, and under the cooperation of the limit groove 1601 and the limit block 1901, the sliding sleeve 19 will also rotate accordingly. In this process, the convex rod 1902 will move along one of the arc grooves 1801 toward the lower convex portion 1802 , causing the sliding fitting 19 to move toward the convex ring 1803 and compress the No. 2 cylindrical spring 20. After the convex rod 1902 moves over the lower convex portion 1802, the No. 2 cylindrical spring 20 will actively release its elastic potential energy and actively drive the connecting shaft 16 to rotate. After the convex rod 1902 moves to the end of the other arc groove 1801, the connecting shaft 16 achieves a certain angle of deflection. At this time, the detection wheel 15 follows the deflection, and when the mortar column rotates, the detection wheel 15 can move toward the other side of the mortar column, so that before each detection, the angle of the detection wheel 15 can be automatically switched, reducing the debugging workload before detection and reducing the difficulty of operation.

[0047] Of course, in order to improve the detection accuracy, the detection wheel 15 can be deflected in the opposite direction after reaching the end of the mortar column, and then the mortar column continues to rotate so that the detection wheel 15 can move in the opposite direction along the mortar column, and a secondary detection can be performed to improve the detection accuracy.

[0048] Through the above arrangement, it is achieved that when the detection wheel 15 moves to the end of the stroke, the cooperation between the convex shaft 2301 and the arc surface 2101 can make the detection wheel 15 deflect in the opposite direction, so that when the mortar column rotates, the detection wheel 15 can move in the opposite direction. On the one hand, it can reduce the debugging workload before detection and reduce the difficulty of operation. On the other hand, it can perform secondary or multiple detections as needed to further improve the detection accuracy.

[0049] As an embodiment of the present invention, a method for detecting drying shrinkage of vitrified microsphere thermal insulation mortar is also proposed, using the detection device, comprising the following steps:

[0050] Step 1: Place the hardened mortar column between the No. 1 roller 4 and the No. 2 roller 5, and control the driving mechanism to drive the two groups of No. 2 rollers 5 to move toward the No. 1 roller 4 until the No. 1 roller 4, the two groups of No. 2 rollers 5 abut against the circumferential surface of the end of the mortar column;

[0051] Step 2: driving the first roller 4 to rotate, so that the mortar column rotates accordingly;

[0052] Step 3: When the mortar column rotates, the detection wheel 15 can make a spiral motion on the circumferential surface of the mortar column;

[0053] Step 4: When the detection wheel 15 moves to the end of the stroke, the trigger assembly is activated to drive the connecting shaft 16 to rotate, and the detection wheel 15 can move in the reverse direction while the mortar column continues to rotate;

[0054] Step 5: Collect the test results and compare them with the inner diameter of the mold for pouring mortar columns.
