Description

Technical Field

[0001] This application relates to the technical field of building construction, and in particular to a device and method for controlling the thickness of masonry mortar joints. Background Technology

[0002] Mortar joints mainly refer to the mortar layer between two adjacent masonry blocks during masonry construction. The main function of mortar joints is to uniformly transmit pressure and provide adhesion, thereby increasing the integrity of the wall. The quality control of mortar joints has always been one of the key points in the construction industry, because the composition and structure of mortar joints are prone to generating internal stress, which affects the mechanical properties of the wall.

[0003] In existing technologies, the thickness of mortar joints is manually controlled during masonry construction. Differences in the skill of construction workers often affect the final quality of the masonry project, making mortar joint quality control particularly important. Previously, the fullness of mortar joints was generally inspected visually, which is heavily influenced by subjective experience and often fails to accurately control the thickness of the mortar joints, leaving room for improvement. Summary of the Invention

The connecting frame is fixed to the lower end of the driven column and is perpendicular to the driven column. The two ends of the connecting frame can slide relative to the two clamping plates along the axial direction of the driven column. The two ends of the support column are fixed to the two ends of the connecting frame one by one. The rotating tube is sleeved on the support column and can rotate relative to the support column in the circumferential direction.

[0047] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0048] This application discloses a device for controlling the thickness of masonry mortar joints. (Refer to...) Figure 1 The masonry mortar joint thickness control device includes a clamping plate 10, a clamping drive mechanism 20, and a mortar joint adjustment mechanism 30.

[0049] Reference Figure 1 and Figure 2 There are two clamping plates 10. Both clamping plates 10 are long rectangular plates. The two clamping plates 10 are parallel to each other and are spaced apart.

[0050] There are two clamping drive mechanisms 20, each located at one end of a clamping plate 10. The two ends of each mechanism are connected to the two clamping plates 10 to drive them closer together. Specifically, each clamping drive mechanism 20 includes a connecting rod 21, an elastic element 22, and a clamping drive disc 23. One end of the connecting rod 21 is perpendicularly fixed to one end of one of the clamping plates 10, and the other end passes through the other end of the other clamping plate 10. The other end of the connecting rod 21 can slide axially relative to the other clamping plate 10, and is stationary circumferentially relative to the other clamping plate 10. The elastic element 22 is a compression spring, but can also be an elastic rubber sleeve or a disc spring. The elastic element 22 is sleeved on the other end of the connecting rod 21 and abuts against the side of the other clamping plate 10 opposite to one of the clamping plates 10. The clamping drive disk 23 is threaded to the other end of the connecting rod 21. The clamping drive disk 23 and another clamping plate 10 are clamped at both ends of the elastic member 22. Rotating the clamping drive disk 23 can drive the elastic member 22 to compress, thereby driving the other clamping plate 10 to approach one of the clamping plates 10, so as to clamp the two clamping plates 10 to both sides of the masonry.

[0051] The connecting rod 21 includes a square rod portion 211 and a screw portion 212. One end of the square rod portion 211 is fixed to one of the clamping plates 10 by a screw, and the other end of the square rod portion 211 passes through another clamping plate 10. The square rod portion 211 can slide relative to the other clamping plate 10 along its length. The screw portion 212 is fixed to the other end of the square rod portion 211, and the clamping drive disk 23 is threadedly connected to the screw portion 212.

[0052] Reference Figure 2 and Figure 3There are two mortar joint adjustment mechanisms 30, each corresponding to one of the square rod portions 211 of the two connecting rods 21. The mortar joint adjustment mechanisms 30 are used to adjust the distance between the upper surfaces of the two clamping plates 10 and the masonry, i.e., the required thickness of the mortar joint. Specifically, each mortar joint adjustment mechanism 30 includes an internal threaded sleeve 31, an external threaded sleeve 32, a driven column 33, and a support column 34. The internal threaded sleeve 31 is fixed to the middle of the square rod portion 211, is vertically arranged, and has internal threads. The external threaded sleeve 32 has external threads and is concentrically inserted into the internal threaded sleeve 31, connected to the internal threaded sleeve 31 via both internal and external threads.

[0053] In some embodiments, the driven column 33 is concentrically inserted into the external threaded sleeve 32, and the upper end of the driven column 33 is threadedly connected to a limiting nut 331, which abuts against the upper end of the external threaded sleeve 32. The support column 34 is welded and fixed to the lower end of the driven column 33, and the support column 34 is perpendicular to the driven column 33. The support column 34 abuts against the lower end of the external threaded sleeve 32 so that the driven column 33 moves synchronously with the external threaded sleeve 32 along the axial direction. The two ends of the support column 34 abut against the two ends of the two clamping plates 10 respectively and can slide relative to the two clamping plates 10 along the axial direction of the driven column 33, so that when the external threaded sleeve 32 is rotated, the driven column 33 only rises and falls synchronously with the external threaded sleeve 32, and does not rotate with the external threaded sleeve 32. This realizes the adjustment of the distance between the lower side of the support column 34 and the upper surface of the clamping plate 10 (i.e., the distance between the upper surface of the masonry and the upper surface of the clamping plate 10), thereby realizing the adjustment of the required thickness of the mortar joint.

[0054] In other embodiments, each mortar joint adjustment mechanism 30 includes a connecting frame 35 and a rotating tube 36. The connecting frame 35 is fixed to the lower end of the driven column 33, and the connecting frame 35 and the driven column 33 are perpendicular to each other. The connecting frame 35 abuts against the lower end of the external threaded sleeve 32 so that the driven column 33 moves synchronously with the external threaded sleeve 32 along the axial direction. The connecting frame 35 is arranged in a U-shape, with the opening of the connecting frame 35 facing downward. The two ends of the connecting frame 35 abut against the two ends of the two clamping plates 10 respectively and can slide relative to the two clamping plates 10 along the axial direction of the driven column 33, so that when the external threaded sleeve 32 is rotated, the driven column 33 only rises and falls synchronously with the external threaded sleeve 32, and does not rotate with the external threaded sleeve 32. The two ends of the support column 34 are fixed to the two ends of the connecting frame 35 respectively. The rotating tube 36 is sleeved on the support column 34 and can rotate relative to the support column 34 in the circumferential direction. The rotating tube 36 can roll and abut against the upper surface of the masonry, realizing the adjustment of the distance between the lower side of the rotating tube 36 and the upper surface of the clamping plate 10 (i.e., the distance between the upper surface of the masonry and the upper surface of the clamping plate 10), thereby realizing the adjustment of the required thickness of the mortar joint.

[0055] To facilitate the rotation of the external threaded sleeve 32, a gripping disc 321 is fixed to the upper end of the external threaded sleeve 32 to increase the gripping area and make it easier for operators to grip and rotate the gripping disc 321.

[0056] Reference Figure 1 and Figure 4 To achieve simultaneous rolling of the mortar joint thickness control device and the moving mortar joint thickness control device, the mortar joint thickness control device also includes support plates 40, rollers 50, and clamping adjustment mechanism 60. A rotating shaft 11 is fixed to the opposite sidewalls of each of the two clamping plates 10, and the rotating shafts 11 are perpendicular to the clamping plates 10. Support plates 40 are correspondingly fitted onto the rotating shafts 11, and can rotate relative to the clamping plates 10 around the rotating shafts 11. Support plates 40 extend vertically and can slide relative to the rotating shafts 11 along their axial direction. Rollers 50 are correspondingly fixed to the lower side of the support plates 40, and are positioned horizontally towards the clamping plates 10. Rollers 50 can roll and abut against both sides of the masonry.

[0057] A clamping adjustment mechanism 60 is mounted on the rotating shaft 11 to drive the support plate 40 closer to the clamping plate 10. The clamping adjustment mechanism 60 can drive the roller 50 to roll and press against the masonry while simultaneously locking the vertically positioned support plate 40 onto the clamping plate 10. Specifically, the clamping adjustment mechanism 60 includes an adjusting elastic element 61 and a clamping adjustment disc 62. The adjusting elastic element 61 is a compression spring and is located between the clamping plate 10 and the support plate 40. The clamping adjustment disc 62 is located on the side of the support plate 40 facing away from the clamping plate 10. The clamping adjustment disc 62 is sleeved on the rotating shaft 11 and threadedly connected to it. Rotating the clamping adjustment disc 62 drives the support plate 40 closer to the clamping plate 10. By adjusting the elastic element 61 and the clamping adjustment disc 62, the vertically positioned support plate 40 is locked in place.

[0058] Reference Figure 4 and Figure 5The clamping and adjusting mechanism 60 also includes a first gear disc 63 and a second gear disc 64. The first gear disc 63 is fixed to the side of the support plate 40 facing the clamping plate 10, and is concentrically sleeved on the rotating shaft 11. The first gear disc 63 has a plurality of locking teeth 631 facing the clamping plate 10 and evenly distributed circumferentially. The second gear disc 64 is concentrically sleeved on the rotating shaft 11 and located between the adjusting elastic member 61 and the first gear disc 63. The second gear disc 64 can slide axially relative to the rotating shaft 11, and has a plurality of adjusting teeth 641 that mesh with the locking teeth 631. Two limiting strips 642 are fixed on the inner sidewall of the second gear disc 64. Both limiting strips 642 extend axially along the rotating shaft 11 and are evenly distributed circumferentially along the second gear disc 64. A limiting groove 111 corresponding to the limiting strip 642 is provided on the outer peripheral wall of the rotating shaft 11. The limiting strip 642 slides in the limiting groove 111 along the axial direction of the rotating shaft 11, so that the second gear plate 64 is fixed relative to the rotating shaft 11 in the circumferential direction. The arrangement of the first gear plate 63 and the second gear plate 64 makes the angle adjustment of the support plate 40 more precise. At the same time, when the support plate 40 is locked in the vertical state, the locking tooth 631 and the adjusting tooth 641 mesh with each other, making the support plate 40 locked more firmly.

[0059] Reference Figure 6 and Figure 7 , Figure 6 and Figure 7 The upper dashed line represents the upper surface of the mortar joint, and the lower dashed line represents the upper surface of the masonry. During operation, first rotate the external threaded sleeve 32 to adjust the distance between the lower side of the rotating tube 36 and the upper side of the clamping plate 10, which is the target mortar joint thickness. Then, the clamping drive mechanism 20 drives the two clamping plates 10 to move closer together and clamp onto the masonry, so that the rotating tube 36 abuts against the upper side of the masonry. During mortar joint construction, mortar is only laid between the two connecting rods 21, leaving space between the mortar joint and the two connecting rods 21 to prevent interference between the connecting rods 21 and the mortar joint. After the mortar joint construction is completed, the clamping drive mechanism 20 allows the clamping plates 10 to slide relative to the masonry while clamping it, controlling the two clamping plates 10 to rotate upwards around one of the rotating tubes 36, so that the lower side of the other rotating tube 36... The side is tangent to the upper surface of the mortar joint; then adjust the support plate 40 to a vertical state, rotate the clamping adjustment disc 62 to drive the support plate 40 close to the clamping plate 10, the clamping adjustment disc 62 cooperates with the adjusting elastic element 61 to clamp the first toothed disc 63 and the second toothed disc 64, locking the vertical support plate 40, and at the same time driving the two rollers 50 to clamp the two sides of the masonry; finally, press down on the connecting rod 21 on the upper side of one of the rotating tubes 36 so that the rotating tube 36 rolls against the upper surface of the masonry, and at the same time pull one of the rotating tubes 36 in the direction indicated by arrow x, so that the mortar joint thickness control device can be moved while the mortar joint is rolled, further improving the accuracy of the mortar joint.

[0060] In addition, in some other embodiments, an upwardly extending connecting block can be fixed on the upper side of the clamping plate 10, and the connecting rod 21 is connected to the connecting block, so that the length of the mortar joint construction can be equal to the length of the clamping plate 10, and the connecting rod 21 will not interfere with the mortar joint. Example 2

[0061] Reference Figure 6 and Figure 7 , Figure 6 and Figure 7 The upper dashed line represents the upper surface of the mortar joint, and the lower dashed line represents the upper surface of the masonry. This application also discloses a method for controlling the thickness of masonry mortar joints, including the following steps:

[0062] S1. Masonry clamping: Adjust the distance between the two clamping plates 10 so that the two clamping plates 10 clamp the two sides of the masonry respectively.

[0063] S2. Adjustment of mortar joint thickness: The distance between the upper surface of the clamping plate 10 and the masonry is adjusted by the mortar joint adjustment mechanism 30. The distance between the upper surface of the clamping plate 10 and the masonry is equal to the required mortar joint thickness.

[0064] S3. Grout joint rolling: Control the two clamping plates 10 to rotate upwards around one of the rotating tubes 36, so that the lower side of the other rotating tube 36 is tangent to the upper surface of the grout joint. Adjust the support plate 40 to a vertical state. Simultaneously, drive the two rollers 50 to clamp the two sides of the masonry through the clamping adjustment mechanism 60, and lock the vertical support plate 40. Pull one of the rotating tubes 36 away from the other rotating tube 36, i.e., along... Figure 7 Pull the rotating tube 36 on the right in the direction indicated by the middle arrow x.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
