Description

Technical Field

[0001] This application relates to the field of concrete walls, and more particularly to a joint structure for applying putty to concrete walls. Background Technology

[0002] Concrete walls refer to building structures made of concrete and steel modules. The main advantages of concrete walls are that they can be commercially produced, have high on-site construction efficiency, low labor intensity, and are relatively lightweight.

[0003] After concrete walls are poured, they need to be coated with putty. Applying putty reduces wall cracking, saves on renovation costs, and facilitates formaldehyde evaporation. However, during the application process, putty may detach from the wall, wasting materials and negatively impacting the construction environment. To catch the detached putty and facilitate its reuse, thus minimizing waste, a putty catcher structure for concrete walls has been designed. This structure uses a catcher groove to catch the detached putty, and a ratchet and sliding rod to flexibly adjust the height of the catcher groove, allowing it to catch putty from different locations and facilitating reuse, thereby reducing material waste. Utility Model Content

[0004] To address the existing technical problems, this application provides a material-removing joint structure for applying putty to concrete walls.

[0005] This application provides a material-attaching structure for plastering concrete walls, which adopts the following technical solution: A material-attaching structure for plastering concrete walls includes a base plate, a support frame fixedly connected to the rear side of the top of the base plate by bolts, a straight rod rotatably connected to the inner cavity of the support frame, a ratchet fixedly connected to the surface of the straight rod, a gear fixedly connected to the surface of the straight rod, the gear being located in front of the ratchet, a spring plate fixedly connected to the left side of the top of the support frame, an arc-shaped pressure plate rotatably connected to the right side of the top of the support frame, and a U-shaped bracket fixedly connected to the top of the base plate by bolts.

[0006] By adopting the above technical solution, the ratchet and gear are rotated by cranking the handle. While the ratchet is rotating, the cooperation between the spring plate and the arc-shaped pressure plate prevents the ratchet from reversing. This causes the gear to drive the large gear and the driven gear to rotate stably, thereby adjusting the height of the putty tray. This reduces the waste of materials caused by the putty falling off the wall during the putty application process, as well as the adverse impact on the construction environment.

[0007] Preferably, the U-shaped bracket is located on the front side of the support frame, and a rotating rod is rotatably connected to the inner cavity of the U-shaped bracket, with a large gear fixedly connected to the surface of the rotating rod.

[0008] Preferably, a driven gear is fixedly connected to the surface of the rotating rod, the driven gear is located in front of the large gear, and a support vertical groove is fixedly connected to the left side of the top of the base plate by bolts, and a sliding rod is slidably connected to the inner cavity of the support vertical groove.

[0009] Preferably, a rack is fixedly connected to the right side of the sliding rod by bolts, and the surface of the rack meshes with the surface of the driven gear.

[0010] Preferably, the inner wall of the supporting vertical groove is provided with a sliding groove, and limit strips are fixedly connected to both the front and rear sides of the sliding rod, with the surface of the limit strips slidably connected to the inner cavity of the sliding groove.

[0011] By adopting the above technical solution and setting the limiting strip, the sliding rod can be limited and supported during the sliding process of the sliding rod in the inner cavity of the vertical groove, which can prevent the putty in the inner cavity of the receiving groove from falling off due to the shaking of the sliding rod.

[0012] Preferably, a spring plate is fixedly connected to the top of the base plate by bolts, the spring plate is located on the bottom side of the inner cavity of the support vertical groove, and the sliding rod is placed on the top of the spring plate.

[0013] By adopting the above technical solution, the spring plate can be used to protect the sliding rod from the base plate and provide auxiliary support when the sliding rod is stationary.

[0014] Preferably, a crank handle is provided on the rear side of the support frame, and the crank handle is fixedly connected to the rear end of the straight rod.

[0015] Preferably, the top of the sliding rod is fixedly connected to a receiving groove by bolts, and a wall is provided on the left side of the base plate.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. This utility model uses a crank handle to drive a ratchet and gear to rotate. As the ratchet rotates, the cooperation between the spring plate and the arc-shaped pressure plate prevents the ratchet from reversing. This, in turn, causes the gear to drive the large gear and the driven gear to rotate stably, thereby adjusting the height of the putty trough. This reduces the waste of materials and adverse effects on the construction environment caused by putty falling off the wall during the putty application process.

[0018] 2. By setting a limiting strip, this utility model can limit and support the sliding rod during the sliding process of the sliding rod in the inner cavity of the vertical groove, which can prevent the putty in the inner cavity of the receiving groove from falling off due to the shaking of the sliding rod.

[0019] 3. By setting the spring plate, this utility model can protect the sliding rod from the base plate and provide auxiliary support for the sliding rod when it is stationary. Attached Figure Description

[0033] Example 1:

[0034] Combination Figure 3 and Figure 5This application discloses a material-attaching structure for plastering concrete walls, including a base plate 1. A support frame 2 is bolted to the rear side of the top of the base plate 1. A straight rod is rotatably connected to the inner cavity of the support frame 2. A ratchet 3 is fixedly connected to the surface of the straight rod, and a gear 4 is fixedly connected to the surface of the straight rod, located in front of the ratchet 3. A spring plate 5 is fixedly connected to the left side of the top of the support frame 2, and an arc-shaped pressure plate 6 is rotatably connected to the right side of the top of the support frame 2. A U-shaped bracket 7 is bolted to the top of the base plate 1, located in front of the support frame 2. A rotating rod is rotatably connected to the inner cavity of the U-shaped bracket 7. A large gear 8 is fixedly connected to the surface of the rotating rod, and a driven gear 9 is fixedly connected to the surface of the rotating rod. Located on the front side of the large gear 8, a supporting vertical groove 10 is fixedly connected to the left side of the top of the base plate 1 by bolts. A sliding rod 11 is slidably connected to the inner cavity of the supporting vertical groove 10. A rack 12 is fixedly connected to the right side of the sliding rod 11 by bolts. The surface of the rack 12 meshes with the surface of the driven gear 9. A sliding groove is opened on the inner wall of the supporting vertical groove 10. Limiting strips 13 are fixedly connected to both the front and rear sides of the sliding rod 11. The surface of the limiting strips 13 is slidably connected to the inner cavity of the sliding groove. By setting the limiting strips 13, the sliding rod 11 can be limited and supported during the sliding process in the inner cavity of the supporting vertical groove 10, which can prevent the putty in the inner cavity of the receiving groove 16 from falling due to the shaking of the sliding rod 11.

[0035] Example 2:

[0036] Combination Figure 1 , Figure 2 and Figure 4 A spring plate 14 is fixedly connected to the top of the base plate 1 by bolts. The spring plate 14 is located on the bottom side of the inner cavity of the support vertical groove 10. The sliding rod 11 is placed on the top of the spring plate 14. The spring plate 14 can protect the sliding rod 11 from the base plate 1 and provide an auxiliary support force when the sliding rod 11 is stationary. A crank handle 15 is provided on the rear side of the support frame 2. The crank handle 15 is fixedly connected to the rear end of the straight rod. A receiving groove 16 is fixedly connected to the top of the sliding rod 11 by bolts. A wall 17 is provided on the left side of the base plate 1.

[0037] Working principle: When using this utility model, the user places the base plate 1 in front of the wall 17 and then cranks the handle 15. At this time, under the support of the support frame 2, the ratchet 3 and gear 4 are driven to rotate. While the ratchet 12 is rotating, the cooperation between the spring plate 5 and the arc-shaped pressure plate 6 prevents the ratchet 3 from reversing. This causes the gear 4 to drive the large gear 8 and the driven gear 9 to rotate stably. At this time, the rack 12 and the driven gear 9 are in a meshing state. Under the limit of the support vertical groove 10, the sliding rod 11 is driven to slide upward stably, thereby adjusting the height of the material groove 16. This reduces the waste of raw materials caused by the attached putty falling off the wall during the putty application process, as well as the adverse impact on the construction environment.

[0038] In summary, this putty application method for concrete walls utilizes a material-dropping joint structure. By cranking the handle 15, the ratchet 3 and gear 4 are rotated. As the ratchet 12 rotates, the cooperation between the spring plate 5 and the curved pressure plate 6 prevents the ratchet 3 from reversing. This, in turn, causes the gear 4 to drive the large gear 8 and the driven gear 9 to rotate stably, thereby adjusting the height of the material-dropping groove 16. This reduces the waste of materials and adverse effects on the construction environment caused by putty falling off the wall during the application process.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
