Description

Technical Field

[0001] This utility model relates to the field of fixed building technology, and in particular to a precise mortar-laying device for masonry structures. Background Technology

[0002] In building construction, aerated concrete blocks are frequently used for infill wall construction. Chinese utility model patent, authorization announcement number "CN211229594U", discloses an integrated device for mortar spreading and grouting in masonry construction, including a horizontal positioning frame and a vertical positioning frame. One end of the horizontal positioning frame is equipped with a guide rod, and the vertical positioning frame can slide up and down along the guide rod. When used for aerated concrete block masonry construction, the horizontal and vertical positioning frames limit the range and thickness of the mortar spreading between the bricks. The horizontal movement of the horizontal positioning frame and the vertical sliding of the vertical positioning frame simultaneously complete the grouting process, ensuring precise control of the mortar thickness and rapid grouting, effectively guaranteeing construction quality and improving construction efficiency.

[0003] The above technical solution involves placing the device on the wall where bricks are to be laid, and controlling the mortar thickness between bricks using horizontal and vertical positioning frames. The vertical positioning frame slides up and down, while the horizontal positioning frame slides horizontally. Horizontal and vertical grouting balls are used to grout the wall horizontally and vertically, respectively. However, this technical solution still has certain drawbacks. For example, while the device controls the mortar thickness between bricks using horizontal and vertical positioning frames, it cannot be adjusted according to the wall width. Therefore, when masonrying different walls, workers need to use auxiliary tools, which increases the workload of workers and reduces the efficiency of masonry work. Utility Model Content

[0012] Preferably, both vertical square tubes are L-shaped, and a second sliding rod is fixedly connected to the upper outer wall of the right vertical square tube;

[0013] The outer wall of the second sliding rod is slidably connected to the groove at the upper end of the left vertical square tube, and both vertical square tubes are slidably sleeved on the outer wall of the support rod.

[0014] Preferably, the upper outer walls of the two support rods are provided with second limiting block grooves, and the interiors of the two second limiting block grooves are slidably connected with limiting blocks. The outer walls of one side of the two vertical square tubes are provided with multiple first limiting block grooves.

[0030] Please see Figure 1-4 This utility model provides a technical solution: a precise mortar laying device for masonry structures, comprising two horizontal square tubes 1 and two vertical square tubes 6;

[0031] Adjustment components are installed on the two horizontal square tubes 1;

[0032] The adjustment assembly includes a crossbar 2 and a first sliding rod 11. The crossbar 2 is fixedly connected to the outer wall of the left horizontal square tube 1, and the first sliding rod 11 is fixedly connected to the outer wall of the right horizontal square tube 1. A first sliding rod groove 12 is formed at the end of the crossbar 2 near the right horizontal square tube 1. The outer wall of the first sliding rod 11 is slidably connected to the inside of the first sliding rod groove 12. The crossbar 2 is provided with a scale. Multiple first fixing bolt grooves 10 are formed on the outer wall of the first sliding rod 11. A first fixing bolt 3 is threadedly connected to the outer wall of the crossbar 2. The threaded end of the first fixing bolt 3 near the first fixing bolt groove 10 extends into the inside of the first sliding rod groove 12 and is threadedly connected to the inside of the corresponding first fixing bolt groove 10. Support rods 13 are fixedly connected to the upper surface of the ends of the two horizontal square tubes 1 away from the crossbar 2. Both vertical square tubes 6 are L-shaped. A second sliding rod 5 is fixedly connected to the upper outer wall of the right vertical square tube 6. The outer wall of the second sliding rod 5 is connected to the groove formed at the upper end of the left vertical square tube 6. The two vertical square tubes 6 are slidably sleeved on the outer wall of the support rod 13. The upper outer wall of the two support rods 13 is provided with a second limiting block groove 14. The inner walls of the two second limiting block grooves 14 are slidably connected with limiting blocks 15. The outer walls of one side of the two vertical square tubes 6 are provided with multiple first limiting block grooves 4. The end of the two limiting blocks 15 near the first limiting block groove 4 extends slidably into the inner wall of the first limiting block groove 4. The inner walls of the two second limiting block grooves 14 are provided with return springs 9. The two ends of the two return springs 9 are fixedly connected to the inner wall of the corresponding second limiting block groove 14 and the outer wall of the limiting block 15, respectively. The upper outer wall of the left vertical square tube 6 is threaded with a second fixing bolt 7. The end of the second fixing bolt 7 near the left vertical square tube 6 extends threadedly into the groove at the upper end of the left vertical square tube 6 and contacts the outer wall of the second sliding rod 5. The outer walls of the two vertical square tubes 6 are provided with scales. The inner walls of the upper ends of the two vertical square tubes 6 are fixedly connected with limiting plates 8.

[0033] Furthermore, when using this device, before the mortar-laying operation in masonry construction, according to actual construction needs, first adjust the lateral dimension of the device, loosen the second fixing bolt 7 on the left vertical square tube 6 to disengage it from the outer wall of the second sliding rod 5, then pull the first sliding rod 11 to slide within the first sliding rod groove 12 of the horizontal bar 2. Using the scale on the horizontal bar 2, adjust the device to a suitable lateral length while simultaneously adjusting the vertical square tube 6. Then tighten the first fixing bolt 3 to thread it into the first fixing bolt groove 10 on the outer wall of the first sliding rod 11, and simultaneously tighten the second fixing bolt 7. This fixes the position of the first sliding rod 11 and the distance between the two vertical square tubes 6, completing the precise adjustment of the lateral dimension of the device. Next, adjust the vertical height by pressing the limiting block 15, causing it to slide within the second limiting block groove 14 and compress the return spring 9. Then, remove the limiting block 15 from the first limiting block groove 4 of the vertical square tube 6. At this point, the two vertical square tubes 6 can slide up and down along the support rod 13. Adjust them to a suitable height according to the scale on the outer wall of the vertical square tube 6. Release the limiting block 15, and the return spring 9 will push the limiting block 15 back into the first limiting block groove 4, fixing the height of the vertical square tube 6. After completing the above adjustments, place the precise mortar-laying device at the masonry structure construction location. The adjusted device precisely positions and controls the mortar-laying position and thickness to ensure the accuracy of the mortar-laying operation and meet the requirements of masonry structure construction.

[0034] By loosening the second fixing bolt 7 on the left vertical square tube 6 in the adjusting device, it is disengaged from the outer wall of the second sliding rod 5. Then, the first sliding rod 11 is pulled to slide in the first sliding rod groove 12 of the horizontal bar 2. Using the scale on the horizontal bar 2, the device is adjusted to a suitable horizontal length while the vertical square tube 6 is adjusted. Then, the first fixing bolt 3 is tightened to connect with the first fixing bolt groove 10 on the outer wall of the first sliding rod 11. At the same time, the second fixing bolt 7 is tightened. This fixes the position of the first sliding rod 11 and the distance between the two vertical square tubes 6, completing the precise adjustment of the horizontal dimension of the device. This allows for adjustment according to the size of different walls, effectively improving the practicality and flexibility of the device.

[0035] Structural Description: Horizontal Square Tube 1: The two horizontal square tubes 1 form the horizontal basic structure of the entire device, serving to support and connect other components. One end is connected to the adjustment component, which allows for adjustment of the horizontal length. The upper surface of the other end is fixedly connected to the support rod 13, providing a support point for the installation and height adjustment of the vertical square tube 6, ensuring the stability of the overall structure of the device and the realization of the horizontal adjustment function.

[0036] Horizontal bar 2: Horizontal bar 2 is fixedly connected to the outer wall of the left horizontal square tube 1. A first sliding groove 12 is opened at one end near the right horizontal square tube 1 for sliding connection with the first sliding rod 11, so as to realize the adjustability of the horizontal length of the device. The horizontal bar 2 is set with scale so that the operator can read the adjusted length value intuitively, thereby accurately controlling the horizontal dimension of the mortar spreading device.

[0037] First slide rod 11: The first slide rod 11 is fixedly connected to the outer wall of the right horizontal square tube 1. Its outer wall is slidably engaged with the inside of the first slide rod groove 12 of the crossbar 2. The outer wall is provided with multiple first fixing bolt grooves 10, which are used in conjunction with the first fixing bolts 3. When the first slide rod 11 slides to the appropriate position, the first fixing bolts 3 are tightened so that their threads extend into the inside of the first slide rod groove 12 and are threadedly connected to the first fixing bolt grooves 10, thereby fixing the position of the first slide rod 11 and ensuring the stability of the device after the lateral length is adjusted.

[0038] First fixing bolt 3: The first fixing bolt 3 is threadedly connected to the outer wall of the crossbar 2. By tightening or loosening the first fixing bolt 3, the position of the first slide bar 11 can be fixed and adjusted. It is a key component in the adjustment assembly to achieve length fixation.

[0039] The two vertical square tubes 6 are L-shaped and are important components for vertical height adjustment and mortar positioning. They are slidably sleeved on the outer wall of the support rod 13 and can slide up and down along the support rod 13 to adjust the height. Multiple first limiting block grooves 4 are opened on one side of the outer wall, which cooperate with the limiting block 15 to fix the vertical height. The upper outer wall is provided with a second sliding rod 5 or a groove that cooperates with the second sliding rod 5 to realize the lateral connection and adjustment between the two vertical square tubes 6. The upper inner wall is fixedly connected to the limiting plate 8, which plays a role in limiting and assisting in fixing. The outer wall is provided with a scale to facilitate the operator to accurately control the value of vertical height adjustment.

[0040] Support rod 13: Two support rods 13 are fixedly connected to the upper surface of the two horizontal square tubes 1 at the end away from the crossbar 2, respectively, to provide support and guidance for the vertical square tube 6, so that the vertical square tube 6 can be stably adjusted up and down. They are key structural components connecting the horizontal square tube 1 and the vertical square tube 6.

[0041] Second slide rod 5: The second slide rod 5 is fixedly connected to the upper outer wall of the right vertical square tube 6, and its outer wall is slidably connected to the inside of the groove opened at the upper end of the left vertical square tube 6, so as to realize the lateral connection and relative sliding adjustment between the two vertical square tubes 6, and further enhance the adaptability of the device in different construction scenarios.

[0042] Limiting block 15: Two limiting blocks 15 are slidably connected to the second limiting block groove 14 on the outer wall of the upper end of the two support rods 13 respectively. One end can slide to the first limiting block groove 4 of the vertical square tube 6. By cooperating with the first limiting block groove 4, the position of the vertical square tube 6 on the support rod 13 is fixed to prevent the vertical square tube 6 from sliding during construction and to ensure the stability of the mortar laying device height.

[0043] Reset spring 9: Two reset springs 9 are respectively set inside the two second limit block grooves 14, and their two ends are fixedly connected to the inner wall of the second limit block groove 14 and the outer wall of the limit block 15, respectively, to provide the limit block 15 with the elastic force for reset. When it is necessary to adjust the height of the vertical square tube 6, press the limit block 15 to compress the reset spring 9, so that the limit block 15 exits the first limit block groove 4. After the adjustment is completed, release the limit block 15, and the reset spring 9 pushes the limit block 15 to re-insert into the first limit block groove 4, so as to quickly fix the height of the vertical square tube 6.

[0044] Second fixing bolt 7: The second fixing bolt 7 is threadedly connected to the outer wall of the upper end of the left vertical square tube 6. When the second slide rod 5 slides to the appropriate position, tighten the second fixing bolt 7 so that its thread extends to the groove opened at the upper end of the left vertical square tube 6 and contacts the outer wall of the second slide rod 5, fixing the position of the second slide rod 5, thereby achieving the stability of the lateral connection between the two vertical square tubes 6.

[0045] Limiting plate 8: Limiting plates 8 are fixedly connected to the inner walls of the upper ends of the two vertical square tubes 6. They play a limiting role during the sliding adjustment of the vertical square tubes 6, preventing the vertical square tubes 6 from sliding excessively. They can also help fix the position of the vertical square tubes 6 and enhance the stability of the device structure.
