Description

Technical Field

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

[0002] Masonry structures are building structures made of bricks, stones, concrete blocks, etc., bonded together with mortar. The uniformity and thickness of the mortar joints (the mortar layer between the blocks) directly affect the mechanical properties, waterproofing, and durability of the structure.

[0003] Traditional mortar joint construction involves a multi-step process: first, the joint thickness is controlled manually using experience or simple tools (such as wooden or metal strips); second, mortar is manually filled, which can easily lead to uneven mortar distribution; and finally, a separate vibrator is used to compact the joint. In existing technologies, joint thickness control, mortar filling, and vibration are separate steps, relying on multiple tools, which is cumbersome and lacks coordination.

[0004] The lack of integrated design for adjusting mortar joint thickness, grout supply, and vibration leads to problems such as large deviations in mortar joint thickness, incomplete grout filling, and insufficient compaction, which in turn causes uneven strength of masonry structures, high risk of leakage, and substandard appearance quality. Utility Model Content

[0005] In order to reduce the problems of incomplete grout filling and insufficient compaction, and to improve the control accuracy of mortar joint thickness, this application provides a mortar joint control tool for masonry structures.

[0006] This application provides a masonry structure mortar joint control tooling, which adopts the following technical solution: A masonry joint control fixture includes an installation frame that is snapped onto the masonry and clamps and limits the opposite sides of the joint. The installation frame is equipped with a thickness control mechanism for adjusting the joint thickness. The installation frame also includes a feeder for supplying mortar to the joint and a vibrator for compacting the joint. The thickness control mechanism includes: The grouting head is mounted on the mounting frame and connected to the feeding component; Top plate, which is slidably disposed within the mounting frame and used to abut against the top of the mortar joint; A sliding sleeve is provided on the top plate and on the grouting head. After the sliding sleeve slides to the designated position, it is locked on the grouting head by a locking member. A buffer assembly is disposed on the top plate and connected to a vibrating rod passing through the top plate. The buffer assembly is used to buffer the force exerted by the vibrating rod on the top plate.

[0007] By adopting the above technical solution, the installation frame is set on the masonry, and then the sliding sleeve is fixed to the position of the grouting head by locking bolts. This adjusts the distance between the top plate and the masonry surface. Then, the material supply component provides grout into the sliding sleeve through the grouting head. The grout is vibrated by a vibrator. At the same time, the buffer component reduces the vibration impact force on the top plate when the vibrator vibrates, reduces the probability of the top plate being displaced due to vibration energy, which reduces the sealing of the mortar joint space, reduces the problems of incomplete grout filling and insufficient vibration compaction, and improves the control accuracy of mortar joint thickness.

[0008] Furthermore, the top plate has an installation groove on the side away from the masonry, and a through hole for the vibrator to pass through. The buffer assembly includes: A connecting plate is slidably disposed in an installation groove and is fixedly connected to a vibrating rod; A sliding block is slidably disposed on the top plate along the width direction of the mounting groove, and two sets of the sliding blocks are respectively located on opposite side walls of the connecting plate; A telescopic rod, wherein the fixed end of the telescopic rod is disposed on the sliding block and the movable end is connected to the connecting plate, and the telescopic rod is used to limit the sliding direction between the connecting plate and the sliding block; A first spring is disposed between the sliding block and the connecting plate and is used to push the connecting plate to slide along the length direction of the mounting groove. The second spring is disposed between the sliding block and the side wall of the mounting groove and is used to push the sliding block to slide within the mounting groove.

[0009] By adopting the above technical solution, the connecting plate and the sliding block are connected by a telescopic rod, so that when the connecting plate slides along the width direction of the mounting groove, the sliding block and the connecting plate slide together, which facilitates the second spring to buffer. When the connecting plate slides along the length direction of the mounting groove, it is buffered by the first spring, and finally a multi-dimensional vibration reduction system is formed, which significantly reduces the impact of the vibrator on the top plate and reduces the probability that the sealing between the top plate and the mounting frame will be reduced due to the displacement of the top plate caused by vibration energy.

[0010] Furthermore, the diameter of the through hole is larger than the diameter of the vibrating rod, and the through hole is used to limit the maximum vibration amplitude of the vibrating rod.

[0011] By adopting the above technical solution, the diameter of the through hole is larger than the diameter of the vibrator, allowing the vibrator to vibrate freely within a certain range, while limiting its maximum amplitude to prevent excessive vibration from damaging the mortar joint structure or causing grout segregation.

[0012] Furthermore, the top plate is provided with a protective cover to protect the mounting groove and the buffer assembly. The protective cover has a circular hole for the vibrator to pass through. The circular hole coincides with the axis of the through hole and has the same diameter.

[0013] By adopting the above technical solution, the protective cover covers the installation groove and buffer components, preventing slurry from seeping in or external debris from interfering, thus extending the service life of the device; at the same time, the round hole and the through hole work together to limit the amplitude of the vibrator.

[0014] Furthermore, the protective cover consists of two sets of symmetrical cover plates, which are locked to the top plate by fixing bolts. The two sets of cover plates have symmetrical semi-circular grooves on the side where they abut against each other, and the two sets of semi-circular grooves abut against each other to form a circular hole.

[0015] By adopting the above technical solution, the symmetrical cover plate is easy to disassemble quickly, facilitates cleaning or replacement of the buffer components, reduces maintenance costs, and at the same time reduces the impact of the vibrator on the installation of the cover plate through the semi-circular groove.

[0016] Furthermore, the locking element is a locking bolt threaded onto the sliding sleeve. When the locking bolt passes through the sliding sleeve and abuts against the outer wall of the grouting head, it locks the sliding sleeve onto the grouting head.

[0017] By adopting the above technical solution, the locking bolts are pressed against the outer wall of the grouting head through the threads, providing high friction to fix the sliding sleeve and preventing the sliding sleeve from shifting under vibration or grouting pressure.

[0018] Furthermore, the mounting frame includes: Mounting plate, which is connected to the grouting head and is parallel to the top plate; The two sets of snap-fit ​​plates are arranged on both sides of the mounting plate and located on opposite sides of the masonry. The opposite sides of the top plate slide and abut against the two sets of snap-fit ​​plates. A limiting strip is disposed on the opposite side of the snap-fit ​​plate and is used to abut against the surface of the masonry. The limiting strip is used to limit the distance between the mounting plate and the surface of the masonry.

[0019] By adopting the above technical solution, the two sets of snap-fit ​​plates press against both sides of the mortar joint, the limiting strip abuts against the masonry surface and forcibly constrains the distance between the installation plate and the masonry, and the top plate slides and contacts the two sets of snap-fit ​​plates, reducing the probability of tooling tilt during installation.

[0020] Furthermore, the feeding component includes: A feed hopper, which is mounted on an installation plate and communicates with the inside of the grouting head; A spiral shaft, which is rotatably mounted on the feed hopper and used to discharge the slurry in the feed hopper toward the injection head; A drive unit, which is disposed on the feed hopper and is used to drive the screw shaft to rotate.

[0021] By adopting the above technical solution, the driving component drives the spiral shaft to rotate, thereby pushing the grout to be evenly delivered to the grouting head. By controlling the rotation speed of the spiral shaft, the amount of grout discharged can be controlled, thereby matching different grout joint size requirements and improving grouting efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The fixture is set on the masonry by two sets of snap-fit ​​plates. The limiting strip ensures the stability of the fixture and controls the distance between the installation plate and the surface of the masonry. Then, the sliding sleeve is placed on the grouting head and fixed with locking bolts to adjust the distance between the top plate and the surface of the masonry. Then, the grout in the feed hopper is discharged into the mortar joint through the drive component and the spiral shaft, thereby improving the control accuracy of the mortar joint thickness.

[0023] 2. After the vibrator is started, it drives the connecting plate to slide in the installation groove. The cooperation of the first spring and the telescopic rod buffers and absorbs the force in the length direction of the installation groove, and the second spring buffers and absorbs the force in the width direction of the installation groove. This reduces the vibration impact force on the top plate when the vibrator is vibrating, and reduces the probability of the top plate being displaced due to vibration energy, which reduces the sealing of the mortar joint space. At the same time, the vibrator reduces the problems of incomplete grout filling and insufficient compaction. Attached Figure Description

[0026] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0027] This application discloses a tooling for controlling mortar joints in masonry structures.

[0028] Reference Figure 1 A masonry structure mortar joint control fixture includes an installation frame 1 that is snapped onto the masonry and clamps and limits the relative sides of the mortar joint; a thickness control mechanism 2 for adjusting the thickness of the mortar joint is provided on the installation frame 1; a feeder 6 for supplying mortar to the mortar joint is provided on the installation frame 1; and a vibrator 3 for vibrating the mortar joint is provided on the installation frame 1.

[0029] Reference Figure 1 The mounting frame 1 includes a mounting plate 11, a snap-fit ​​plate 12, and a limiting strip 13. The mounting plate 11 is a rectangular plate structure. Two sets of snap-fit ​​plates 12 are provided, with the two sets of snap-fit ​​plates 12 located on both sides of the rectangular plate along its length. The two sets of snap-fit ​​plates 12 are located on opposite side walls of the masonry, thereby tightening and limiting the side walls of the mortar joint. The limiting strip 13 is fixedly installed on the opposite side of the snap-fit ​​plate 12. The limiting strip 13 is used to abut against the surface of the masonry, thereby preventing the snap-fit ​​plate 12 from sliding down along the side wall of the masonry. The limiting strip 13 cooperates with the snap-fit ​​plate 12 to limit the distance between the mounting plate 11 and the surface of the masonry.

[0030] Reference Figure 1 and Figure 2 The thickness control mechanism 2 includes a grouting head 21, a top plate 22, and a sliding sleeve 23. The grouting head 21 is fixedly installed on the mounting frame 1 and is connected to the feeding component 6. The top plate 22 is a rectangular plate and is slidably installed between two sets of snap-fit ​​plates 12. The top plate 22 is parallel to the mounting plate 11 and is used to press against the top of the grout joint. The sliding sleeve 23 is fixedly installed on the top plate 22 and is located on the grouting head 21. 22. The two sets of snap-fit ​​plates 12 and the masonry surface form a mortar joint space 24. The sliding sleeve 23 is used to discharge the grout discharged from the grouting head 21 into the mortar joint space 24 for grouting. By adjusting the position of the sliding sleeve 23 on the grouting head 21, the distance between the top plate 22 and the masonry surface can be adjusted, thereby adjusting the mortar joint thickness. The sliding sleeve 23 is provided with a locking element 25, which is used to lock the sliding sleeve 23 on the grouting head 21.

[0031] Reference Figure 1 The locking element 25 is a locking bolt threaded on the sliding sleeve 23. The locking bolt passes through the sliding sleeve 23 and abuts against the outer wall of the grouting head 21. When the locking bolt is not abutted against the outer wall of the grouting head 21, the sliding sleeve 23 can slide freely on the grouting head 21. When the locking bolt abuts against the outer wall of the grouting head 21, the sliding sleeve 23 is locked on the grouting head 21, thereby controlling the distance between the top plate 22 and the masonry surface, and thus controlling the thickness of the mortar joint space 24.

[0032] Reference Figure 3 and Figure 4 The thickness control mechanism 2 also includes a buffer assembly 4. A vibrating rod 3 for vibrating the mortar joint is fixedly installed on the mounting plate 11. The buffer assembly 4 is set on the top plate 22 and is connected to the vibrating rod 3 that passes through the top plate 22. The buffer assembly 4 is used to buffer the force of the vibrating rod 3 on the top plate 22. An installation groove 221 is opened on the side of the top plate 22 away from the masonry. The buffer assembly 4 is set in the installation groove 221. A through hole 222 is opened on the top plate 22 to facilitate the passage of the vibrating rod 3. The diameter of the through hole 222 is larger than the diameter of the vibrating rod 3. The through hole 222 is used to limit the maximum vibration amplitude of the vibrating rod 3. In this embodiment, two sets of vibrating rods 3 are set on the mounting plate 11 and two sets of buffer assemblies 4 are set on the top plate 22.

[0033] Reference Figure 4 The buffer assembly 4 includes a connecting plate 41, a sliding block 42, a telescopic rod 43, a first spring 44, and a second spring 45. The connecting plate 41 is slidably installed in the middle of the mounting groove 221. The length and width of the connecting plate 41 are both smaller than the length and width of the mounting groove 221, so that the connecting plate 41 can move freely within the mounting groove 221. The connecting plate 41 is fixedly connected to the vibrator 3. The sliding block 42 is slidably installed on the top plate 22 along the width direction of the mounting groove 221. Two sets of sliding blocks 42 are located on opposite side walls of the connecting plate 41. The fixed end of the telescopic rod 43 is fixedly installed on the sliding block 42, and the movable end of the telescopic rod 43 is fixedly connected to the connecting plate 41. The extension and retraction direction of the telescopic rod 43 is parallel to the length direction of the mounting groove 221. The telescopic rod 43 is used to limit the connection. The sliding direction between the connecting plate 41 and the sliding block 42 is as follows: when the connecting plate 41 slides along the width direction of the mounting groove 221, the sliding block 42 slides together with the connecting plate 41 through the telescopic rod 43, and the distance between the connecting plate 41 and the sliding block 42 remains unchanged; when the connecting plate 41 slides along the extension direction of the telescopic rod 43, the position of the sliding block 42 remains fixed, and the telescopic rod 43 extends and retracts; the first spring 44 is sleeved on the telescopic rod 43, and the two ends of the first spring 44 are respectively pressed between the sliding block 42 and the connecting plate 41. The first spring 44 is used to push the connecting plate 41 to slide along the length direction of the mounting groove 221; the second spring 45 is fixedly installed between the sliding block 42 and the side wall of the mounting groove 221. The second spring 45 is used to push the sliding block 42 to slide within the mounting groove 221.

[0034] Reference Figure 4 Specifically, when the vibrating rod 3 vibrates, the vibrating rod 3 drives the connecting plate 41 to slide in the mounting groove 221. Through the buffering effect of the first spring 44 and the second spring 45, the force of the connecting plate 41 on the top plate 22 is reduced.

[0035] Reference Figure 2 and Figure 3The top plate 22 is provided with a protective cover 5 to protect the mounting groove 221 and the buffer assembly 4. The protective cover 5 has a circular hole 51 for the vibrator 3 to pass through. The circular hole 51 coincides with the axis of the through hole 222 and has the same diameter. In order to facilitate the installation and disassembly of the protective cover 5, the protective cover 5 is composed of two sets of symmetrical cover plates 52. The cover plates 52 are fixed and locked to the top plate 22 by fixing bolts. The two sets of cover plates 52 have semi-circular grooves symmetrically opened on the side where they abut against each other. The two sets of semi-circular grooves abut against each other to form the circular hole 51.

[0036] Reference Figure 1 The feeding component 6 includes a feeding hopper 61, a screw shaft 62, and a driving component 63. The feeding hopper 61 is fixedly installed on the mounting plate 11, and the bottom of the feeding hopper 61 is connected to the inside of the grouting head 21. The screw shaft 62 is rotatably installed on the feeding hopper and is used to discharge the grout in the feeding hopper 61 to the grouting head 21. The driving component 63 is fixedly installed on the feeding hopper 61 and is used to drive the screw shaft 62 to rotate, thereby discharging the grout in the feeding hopper 61 into the grouting head 21, and finally discharging it into the mortar joint space 24 through the sliding sleeve 23. In this embodiment, the driving component 63 is a motor fixedly installed on the feeding hopper 61.

[0037] The working principle of this application embodiment is as follows: Two sets of snap-fit ​​plates 12 are snapped onto the masonry. The limiting strip 13 ensures the stability of the tooling and controls the distance between the mounting plate 11 and the masonry surface. Then, the sliding sleeve 23 is positioned on the grouting head 21 and fixed by the locking bolt to adjust the distance between the top plate 22 and the masonry surface. Then, the grout in the feed hopper 61 is discharged into the mortar joint space 24 by the drive component 63 and the spiral shaft 62. Then, the grout in the mortar joint space 24 is vibrated by the vibrating rod 3. At the same time, the extension and retraction of the first spring 44 and the second spring 45 absorb the vibration impact, reduce the probability of the top plate 22 being displaced due to vibration energy, reduce the problem of incomplete grout filling and insufficient vibration compaction, and improve the control accuracy of mortar joint thickness.
