Description

Technical Field

[0001] The present invention relates to a brick joint smearing device for strengthening brick walls with UHP-ECC materials, belonging to the technical field of building construction. Background Art

[0002] UHP-ECC material, also known as ultra-high performance engineered cementitious composite, is a new type of building material with excellent properties developed on the basis of ECC materials. UHP-ECC materials have the performance characteristics of ultra-high strength, good ductility and toughness, high durability, and excellent self-healing ability, and are currently widely used in fields such as building engineering and bridge engineering.

[0003] In the prior art, when using UHP-ECC materials to strengthen brick walls, it is necessary to smear the UHP-ECC materials at the brick joint positions of the brick walls. Therefore, corresponding smearing devices are required. Most of the common brick joint smearing devices on the market at present cannot automatically feed the wall, and workers need to manually feed the wall during use, which increases the time required for smearing the brick joints of the wall and reduces the overall work efficiency. For this reason, the invention patent with the Chinese patent application number CN202110291479.9 discloses a building infill wall block masonry device, which can smear mortar at the horizontal and vertical joints between blocks through the setting of a horizontal mortar scraping system and a vertical mortar smearing system. The set mortar injection nozzle and connecting frame can realize automatic feeding of the wall, thereby reducing the time required for smearing work. However, it still has the following problems when in use: 1. When in use, it needs to be pre-positioned and installed at the front side position of the wall, which results in more time spent on the pre-step before smearing work and actually has little improvement in work efficiency.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1: Please refer to Figures 1 to 5 , this embodiment provides a brick joint smearing device for strengthening brick walls with UHP-ECC materials, including a smearing mechanism 1, and a moving mechanism 2 and a stabilizing mechanism 3 are arranged at the bottom of the smearing mechanism 1.

[0024] In this embodiment, the smearing mechanism 1 includes a stirring frame 101, a bottom motor 102 is arranged at the bottom of the stirring frame 101, the output shaft of the bottom motor 102 is connected by a coupling to a rotating stirring column 103 extending into the stirring frame 101, a slurry suction pipe 104 is arranged on the front side wall of the stirring frame 101, one end of the slurry suction pipe 104 is communicated with the stirring frame 101, and a slurry suction device 105 is arranged at the other end. The slurry suction pipe 104 is communicated with the slurry inlet of the slurry suction device 105. The bottom of the slurry suction device 105 is fixedly provided with a front extension plate 106, and the front extension plate 106 is also fixedly connected to the front side wall of the stirring frame 101. One end of an outlet slurry threaded pipe 107 is connected to the outlet of the slurry suction device 105. The outer wall of the other end of the outlet slurry threaded pipe 107 is threadedly connected to a rotating thread lock 108, and the inner wall of the rotating thread lock 108 is also threadedly connected to one end of an adapter threaded pipe 109. The setting of the rotating thread lock 108 can connect the outlet slurry threaded pipe 107 and the adapter threaded pipe 109. The other end of the adapter threaded pipe 109 is connected to one end of a slurry discharge hose 110, the other end of the slurry discharge hose 110 is connected to a smearing plate 111, the slurry discharge hose 110 is arranged through the smearing plate 111, and a handle 112 is also arranged on the smearing plate 111.

[0025] Through the foregoing settings, when plastering work needs to be carried out, the staff injects UHP-ECC material and water in an appropriate proportion into the mixing frame 101, and then controls the bottom motor 102 to start working. After the bottom motor 102 starts working, its output shaft can drive the rotating mixing column 103 to start rotating through rotation. After the rotating mixing column 103 starts rotating, it can fully mix the UHP-ECC material and water in the mixing frame 101. After the mixing is completed, the staff aligns the plastering board 111 with the position to be plastered by using the handle 112, and then controls the slurry pumping device 105 to start working. The slurry pumping device 105 can be a pump machine such as a slurry pump commonly used in the prior art. The slurry pumping device 105 can pump out the UHP-ECC material that has been mixed in the mixing frame 101 through the slurry pumping pipe 104, and then convey the UHP-ECC material to the discharge hose 110 through the slurry outlet threaded pipe 107 and the connecting threaded pipe 109. Then, the discharge hose 110 conveys the UHP-ECC material to the wall surface aligned by the plastering board 111. After that, the staff can perform the required plastering and filling work by sliding the plastering board 111, which can automatically feed the wall during plastering and does not require the staff to manually assist in feeding the wall, thereby reducing the work content of the staff, reducing the work complexity of the staff, reducing the time required for plastering the brick joints of the wall, improving the work efficiency of the overall work, and being beneficial to the long-term use of the plastering device.

[0026] In this embodiment, the moving mechanism 2 includes side extension plates 201 symmetrically arranged on the left and right side walls of the mixing frame 101. The length of the side extension plates 201 is equal to the length of the mixing frame 101 for connection with subsequent components. At the bottom of both side extension plates 201, movable wheels 202 are rotatably arranged. The number of movable wheels 202 is four, and two movable wheels 22 are arranged on each side extension plate 201 and are symmetrically arranged. The setting of the movable wheels can facilitate the movement of the plastering device to facilitate the conversion of the plastering device at different working positions.

[0027] In this embodiment, the moving mechanism 2 further includes fixing blocks 203 arranged on the front side wall of the mixing frame 101. The fixing blocks 203 are symmetrically arranged on the mixing frame 101. A moving handle 205 is connected to both fixing blocks 203 by inserting a limit bolt 204. The moving handle 205 is arranged in a U-shaped structure. The two end portions of the moving handle 205 are respectively connected to the corresponding fixing blocks 203 by inserting the limit bolt 204. The setting of the moving handle 205 enables the staff to pull the plastering device by means of the moving handle 205, so that the plastering device can be moved more conveniently.

[0028] In this embodiment, the stabilizing mechanism 3 includes lifting bottom columns 301 fixedly connected to the bottom of the stirring frame 101. The lifting bottom columns 301 can be lifters such as lifting cylinders commonly used in the prior art. The number of the lifting bottom columns 301 is four, and the lifting bottom columns 301 are arranged in a rectangular distribution on the stirring frame 101. Base plates 302 are also symmetrically arranged at the bottom of the stirring frame 101, and the two base plates 302 are fixedly connected to the bottoms of the lifting bottom columns 301 on the same side. The arrangement of the lifting bottom columns 301 in cooperation with the base plates 302 enables that when the spreading device does not need to move, the staff controls the lifting bottom columns 301 to start working, making the lifting bottom columns 301 rise and become longer, so that the base plates 302 can lift the spreading device, making the movable wheels 202 not in contact with the ground, and thus enabling the spreading device to be stably in the required position.

[0029] When the brick joint spreading device provided in the first embodiment is in use, since the diameter of the slurry discharge hose is constant, the diameter of the UHP-ECC material transported from the slurry discharge hose to the position of the spreading plate is also constant. However, in actual use, the bricks used for the brick wall have different sizes. Therefore, the brick joints between the bricks also have size differences. If the same discharge diameter is always maintained, it may cause the applied material to be too thin or too thick after being spread on the brick joints, thus affecting the spreading effect. For this reason, on the basis of the first embodiment, the second embodiment is proposed.

[0030] Embodiment Two: Please refer to Figures 6 to 10 , this embodiment provides a brick joint spreading device for strengthening a brick wall with UHP-ECC material, including all the structures in the first embodiment. Further, an adjusting mechanism 4 is also arranged in the spreading plate 111, and the adjusting mechanism 4 is used to adjust the cross-sectional area of the nozzle of the slurry discharge hose 110.

[0031] In this embodiment, the adjusting mechanism 4 includes a rubber ring 401 fixedly sleeved at the nozzle position of the slurry discharge hose 110. A fixing groove 402 is provided on the rubber ring 401 and is arranged around the rubber ring 401. A strap 403 is wound in the fixing groove 402, and the strap 403 is wound in the fixing groove 402 for at least one turn. An installation cavity 404 is formed in the coating plate 111, and the slurry discharge hose is arranged to penetrate through the installation cavity 404. The strap 403 is located in the installation cavity 404. Symmetrically arranged slide rails 405 are provided in the installation cavity 404. Slide blocks 406 are slidably connected to both sides of the slide rails 405. The two ends of the strap 403 are respectively fixedly connected to the two slide blocks 406. The two slide blocks 406 are connected together by a connecting rod. When the two slide blocks 406 slide along the corresponding slide rails 405, they can drive the two ends of the strap 403 to move in the corresponding directions, so that the strap 403 in the installation cavity 404 can perform corresponding tightening or loosening actions on the installation cavity 404, so that the strap 403 can change the nozzle cross-sectional area of the slurry discharge hose 110, thereby realizing the change of the discharge diameter. A driving motor 407 is also provided in the coating plate 111. A lead screw 408 is connected to the electric spindle of the driving motor 407, and one end of the lead screw 408 movably penetrates into the installation cavity 404. The arrangement direction of the lead screw 408 is parallel to the arrangement direction of the slide rails 405. The lead screw 408 movably penetrates through the connecting rod. A lead screw nut 409 is threadedly connected to the lead screw 408, and the lead screw nut 409 is fixedly connected to the connecting rod. The driving motor 407, the lead screw 408 and the lead screw nut 409 are provided to drive the two slide blocks 406 to slide on the corresponding slide rails 405. Specifically, when the driving motor 407 starts to work, it can drive the lead screw 408 to rotate. After the lead screw 408 rotates, it can drive the lead screw nut 409 to perform corresponding movements along the lead screw 408, thereby driving the connecting rod to move, and further driving the two slide blocks 406 to slide on the corresponding slide rails 405. A control button 410 is also provided on the coating plate. The control button 410 is electrically connected to the driving motor 407. The staff can control the working state of the driving motor 407 by using the control button 410.

[0032] With the above settings, during the plastering process, when the staff member finds that the mortar joints between the bricks are small, the staff member can start the driving motor 407 to work, so that the driving motor 407 drives the two sliders 406 to move away from the slurry discharge hose 110, so as to pull the two straps 403, making the straps 403 tighten in the installation cavity 404, so as to change the cross-sectional area of the nozzle of the slurry discharge hose 110 and make it smaller, thereby changing the discharge diameter of the slurry discharge hose 110 to adapt to the smaller mortar joints. When the staff member finds that the mortar joints between the bricks are small, the staff member can start the driving motor 407 to work, so that the driving motor 407 drives the two sliders 406 to move closer to the slurry discharge hose 110, making the straps 403 relax in the installation cavity 404. At this time, the slurry discharge hose 110 can be reset accordingly under the pressure of the discharged material, so as to expand its nozzle cross-sectional area and change the discharge diameter to adapt to the larger mortar joints. Through the setting of the adjusting mechanism 4, the discharge diameter of the slurry discharge hose 110 can be flexibly changed to adapt to the plastering work of mortar joints of different sizes, thus ensuring the plastering effect well.
