Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically a plastering device for wall ends. Background Technology

[0002] In the field of construction engineering, wall plastering, as a fundamental process for decoration and protection, directly affects the overall aesthetics, functionality, and long-term durability of buildings. With the industry's increasing demands for standardized and meticulous construction, the control of key indicators such as wall flatness and verticality is receiving increasing attention. However, in actual construction, special areas such as wall ends and internal / external corners often become weak points in quality control due to limited operating space and the insufficient adaptability of traditional tools.

[0003] Currently, plastering work at wall ends relies heavily on manual experience, using traditional tools such as trowels and straightedges. Due to the lack of effective positioning and guiding benchmarks, workers struggle to consistently control the thickness and uniformity of the plaster layer on narrow surfaces, easily leading to uneven plaster thickness and noticeable joints. These defects not only affect the fit and sealing of subsequent door and window installations but can also cause stress concentration, resulting in plaster layer hollowing, cracking, or even partial detachment, increasing the probability of rework and material waste. Therefore, how to standardize plastering work at wall ends under complex construction site conditions has become a noteworthy technical issue in this field. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned problems, thereby providing a standardized plastering device for wall ends.

[0005] The technical solution adopted by the present invention to solve the aforementioned problem is as follows: A plastering device for wall ends includes columns located on both sides of the wall, a connecting locking mechanism between the columns that can adjust the spacing to clamp the wall, a sliding mechanism that can move longitudinally on each column, a plastering mechanism opposite to the wall end face between the sliding mechanisms, and a material feeding mechanism between the sliding mechanisms and above the plastering mechanism, with the discharge end of the material feeding mechanism opposite to the top of the plastering mechanism.

[0006] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art: The device is fixed to the wall by a locking mechanism, providing a stable working benchmark for plastering operations and helping to reduce construction errors caused by tool shaking. The sliding mechanism drives the plastering mechanism to move longitudinally along the wall, keeping the plastering trajectory straight and improving the uniformity of mortar distribution. The cooperation between the material feeding mechanism and the plastering mechanism enables continuous supply and synchronous spreading of mortar. During construction, plastering can be carried out from bottom to top, with material added to the material feeding mechanism while plastering, achieving continuous operation. This provides conditions for controlling the consistency of the plaster layer thickness, thereby reducing the possibility of rework and repair to a certain extent.

[0007] As a preferred embodiment, a further technical solution of the present invention is: Furthermore, at least two locking mechanisms are provided longitudinally between the columns. This arrangement enhances the stability of the connection between the device and the wall, reduces the deflection that may occur with single-point fixing, and ensures that the device remains in a more reliable fixed state during construction.

[0008] Furthermore, each connection locking mechanism includes two U-shaped positioning frames. The opposing sides of the uprights are fixed to one end of the positioning frame, and the other end of the positioning frame extends to the front of the end face of the wall and is positioned opposite to it. The opposing ends of the two positioning frames are connected to threaded rods with opposite thread directions. A bidirectional threaded sleeve is connected between the threaded rods. This structure can synchronously drive the threaded rods on both sides to move in opposite directions by rotating the bidirectional threaded sleeve, thereby realizing the tightening and opening of the positioning frames. This allows the device to adapt to walls of different thicknesses and perform quick clamping and fixing, making the operation more convenient.

[0009] Furthermore, the sliding mechanism includes a slider, and a T-shaped groove is provided on the column along the longitudinal direction. The slider slides in the groove and one end is located outside the groove. The cooperation between the T-shaped groove and the slider helps to maintain the stability of the slider's movement direction, reduces its shaking during the sliding process, and provides guidance for the smooth lifting and lowering of the plastering mechanism.

[0010] Furthermore, the plastering mechanism includes a connecting rod located on the outer side of the wall end face. Both ends of the connecting rod pass through and are rotatably connected to the slider. A roller for plastering the wall end face is installed on the middle part of the connecting rod. Both ends of the connecting rod are connected to an operating rod that drives its rotation. The rotatably connected connecting rod allows the roller to roll flexibly when it contacts the wall surface, which helps to spread the plaster more evenly. The operating rod provides a convenient point of force for the construction personnel, making it easy to control the rotation and movement of the roller.

[0011] Furthermore, the feeding mechanism includes a feeding hopper fixed between the outer ends of the slider, and the discharge port at the bottom of the feeding hopper is located directly above the roller and is the same length as the roller. The design of the discharge port being the same length as the roller and facing the top of the roller allows the ash material to fall more evenly onto the roller surface, which is conducive to the uniform distribution of the ash material along the width direction of the wall end, creating favorable conditions for subsequent smoothing operations. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of an embodiment of the present invention; The components in the diagram are labeled as follows: 1. Column; 2. Positioning frame; 3. Threaded rod; 4. Bidirectional threaded sleeve; 5. Slider; 6. Roller; 7. Operating lever; 8. Feed hopper. Detailed Implementation

[0013] The present invention will be further described below with reference to embodiments, which are intended only to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0014] A plastering device for wall ends includes columns 1 located on both sides of the wall, a connecting locking mechanism between the columns 1 that can adjust the spacing to clamp the wall, sliding mechanisms that can move longitudinally on the columns 1, a plastering mechanism opposite to the wall end face between the sliding mechanisms, and a material feeding mechanism between the sliding mechanisms and above the plastering mechanism, with the discharge end of the material feeding mechanism opposite to the top of the plastering mechanism.

[0015] Furthermore, at least two locking mechanisms are longitudinally arranged between the columns 1. This arrangement enhances the stability of the connection between the device and the wall, reduces the deflection that may occur with single-point fixing, and enables the device to maintain a more reliable fixed state during construction.

[0016] Furthermore, each connection locking mechanism includes two U-shaped positioning frames 2, which are assembled by on-site welding of square steel. The opposing sides of the columns 1 are fixed to one end of the positioning frame 2, and the other end of the positioning frame 2 extends to the front of the end face of the wall and is set opposite to it. The opposing ends of the two positioning frames 2 are connected to threaded rods 3 with opposite thread directions. A bidirectional threaded sleeve 4 is connected between the threaded rods 3. This structure can synchronously drive the threaded rods 3 on both sides to move in opposite directions by rotating the bidirectional threaded sleeve 4, thereby realizing the tightening and opening of the positioning frame 2. This allows the device to adapt to walls of different thicknesses and perform quick clamping and fixing, making the operation more convenient.

[0017] Furthermore, the sliding mechanism includes a slider 5, and a T-shaped groove is provided on the column 1 along the longitudinal direction. The slider 5 slides in the groove and one end is located outside the groove. The cooperation between the T-shaped groove and the slider 5 helps to maintain the stability of the slider 5's movement direction, reduces its shaking during the sliding process, and provides guidance for the smooth lifting and lowering of the plastering mechanism.

[0018] Furthermore, the plastering mechanism includes a connecting rod located on the outer side of the wall end face. The two ends of the connecting rod pass through the slider 5 and are rotatably connected to it. A roller 6 for plastering the wall end face is installed on the middle part of the connecting rod. The two ends of the connecting rod are connected together by an operating rod 7 that drives its rotation. The rotatably connected connecting rod allows the roller 6 to roll flexibly when it contacts the wall surface, which helps to spread the plaster more evenly. The setting of the operating rod 7 provides a convenient point of force for the construction personnel, making it easy to control the rotation and movement of the roller 6.

[0019] Furthermore, the feeding mechanism includes a feeding hopper 8 fixed between the outer ends of the slider 5, and the discharge port at the bottom of the feeding hopper 8 is located directly above the roller 6 and is the same length as the roller 6. The design that the discharge port is the same length as the roller 6 and is directly above the roller 6 allows the ash material to fall more evenly onto the surface of the roller 6, which is conducive to the uniform distribution of the ash material along the width direction of the wall end, creating favorable conditions for subsequent smoothing operations.

[0020] It should be noted that rollers 6 and hoppers 8 of corresponding lengths must be selected for different wall end widths. Since standardized wall designs are typically used on the same construction site, the end face specifications are relatively uniform, generally only a few fixed sizes. Therefore, rollers 6 and hoppers 8 of corresponding sizes can be pre-equipped for these standard specifications, and selected according to actual needs during construction. This setup ensures the applicability of the device while avoiding resource waste and management inconvenience caused by too many specifications.

[0021] In use, the device is first placed across the end of the wall to be plastered, with the two columns 1 positioned on either side of the wall. By rotating the bidirectional threaded sleeves 4 in each connecting locking mechanism, the two threaded rods 3 with opposite thread directions move synchronously towards each other, thereby driving the U-shaped positioning frame 2 to tighten and securely clamp the device to the wall. This setup overcomes the problem of traditional wall-end plastering lacking an effective positioning benchmark, providing a stable working platform for subsequent operations. Next, plaster is added to the hopper 8. The construction worker holds the operating rod 7 and, starting from the bottom of the wall end, rotates the connecting rod through the operating rod 7 to drive the roller 6, simultaneously pushing the slider 5 along the T-shaped slide on the column 1. The trough slides smoothly upwards. During this process, the discharge port at the bottom of the hopper 8 continuously and evenly guides the mortar to the surface of the roller 6 directly below it. The roller 6 then rolls and applies the mortar to the wall end, realizing continuous operation of moving, adding material, and plastering from bottom to top. This process helps to improve the problems of uneven mortar thickness and obvious joints that are easy to occur in traditional manual plastering. After completing a section of plastering, mortar can be added to the hopper 8 again, and the above operation is repeated until the entire wall end is plastered. The overall use of this device provides an effective means to control the flatness and verticality of the wall end plastering, which helps to reduce rework and repairs caused by construction quality defects.

[0022] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. All equivalent changes made based on the description and drawings of the present invention are included within the scope of the present invention.
