Description

Technical Field

[0001] This utility model relates to a wall inside corner plastering tool, specifically an improved wall inside corner plastering tool for building construction, mainly used for building wall inside corner construction, belonging to the field of building construction technology. Background Technology

[0002] As is well known, unevenness is easily created at the inner corners (concave corners) of walls where two walls meet, and unevenness or bumps can easily occur during plastering. Concave corner construction effectively protects the contact areas of walls, ceilings, etc., from damage, preventing impacts, wear, or other physical damage to the corners, ensuring the long-term effect of the decoration, improving the overall decoration effect, and ensuring the quality and aesthetics of the renovation.

[0003] Currently, when plastering and applying putty to buildings, the inside right angle is very difficult to handle. During construction, it is necessary to use a metal plate or scraper to repair it back and forth, but in the end, the inside corner surface still cannot achieve the effect of a right angle, or the inside corner line cannot achieve the effect of a straight line.

[0004] Although there are specialized tools available for plastering inside corners, the existing technology still has the following technical shortcomings:

[0005] On the one hand, there are hanging plastering tools with right angles. On construction sites, many workers simply pile their plastering tools directly on the ground. When not in use for a long time or during the rainy season, they are prone to getting damp, rusting, or being damaged due to improper storage. Furthermore, during storage, tools are easily scattered or lost on the work site, increasing maintenance and replenishment costs.

[0006] On the other hand, traditional wall corner plastering tools are used, but these lack corresponding control or calibration devices. During construction, the quality of the lines found can only be determined visually, and the resulting wall corner lines often fail to meet the requirements of horizontal and vertical straightness. Furthermore, the structural inspection of this construction work lacks quantitative indicators, relying only on qualitative evaluation criteria.

[0007] To check whether the corner moldings meet the quality requirements, a second manual inspection is required. This wastes both labor and building materials. If the construction results do not meet the requirements, the completed work must be discarded and redone. In short, it is often very inconvenient.

[0008] Therefore, the key to solving the above-mentioned technical problems lies in developing an improved wall corner plastering tool that is easy to store and hang, not easy to lose, and has high reliability. Summary of the Invention

[0009] In view of the many defects and shortcomings of the above-mentioned background technology, this utility model has made improvements and innovations. The purpose is to provide a design with a simple structure, which is easy to hang, store and keep, easy to operate, and significantly improves construction quality and efficiency. It can be recognized by a wide range of operators, effectively improve the construction quality of inside corners, make the construction of mortar plastering at wall corners simple and convenient, quick to form, and produce a smooth surface and beautiful corner shape, thus accelerating the construction progress and saving resources and costs. On the one hand, construction workers can hang tools on the wall or tool rack through the hanging holes, saving storage space and avoiding damage caused by tools being placed randomly. On the other hand, the hanging holes allow tools to be conveniently hung in the required position, and construction workers can more quickly retrieve and adjust tools, reducing unnecessary time waste and improving construction efficiency.

[0010] To solve the above problems and achieve the above-mentioned invention objectives, this utility model provides an improved wall corner plastering tool for building construction, achieved through the following design structure and the following technical solution:

[0011] As an improvement to the wall corner plastering tool for building construction, this utility model includes:

[0012] The working end face of the internal corner plastering body (1) is used to contact the internal corner of the wall (6) and work together to complete the plastering work;

[0013] The handle reinforcing link (2) is connected at one end to the lower middle part of the non-working end face of the corner plastering body (1), and at the other end to the corner plastering handle (3).

[0014] The corner plastering handle (3) has a mounting base (4) extending from the middle of its upper end;

[0015] Mounting base (4), with hanging holes (41) on both sides through the middle of the upper end of the mounting base (4) for easy storage and hanging.

[0016] As an improvement of the present invention, it also includes a leveling tool (5), which is connected to the outer wall of the mounting base (4).

[0017] As a further improvement of the present invention, the leveling tool (5) is a universal level.

[0018] As a further improvement of the present invention, the inside corner plastering body (1) is formed by connecting two plastering boards with the same shape and structure, and the two plastering boards form an included angle of 90°.

[0019] As a further improvement of the present invention, the corner plastering body (1) is an integrally formed fixing plate.

[0020] As a further improvement of the present invention, the corner plastering body (1) is a repairable board, and the upper part of the repairable board is composed of several

[0021] The L-shaped corner trowels (11) are connected sequentially from top to bottom to form an L-shaped plate-like component, wherein a cutting edge (12) is provided between adjacent L-shaped corner trowels (11).

[0022] As a further improvement to the present invention, the handle reinforcing link (2) is composed of two rod-shaped components of different lengths, wherein,

[0023] One end of a handle reinforcing link (2) is connected to the corner of the non-working end of the plastering body (1), and the other end is connected to the upper outer wall of the plastering handle (3).

[0024] Another handle reinforcing link (2) is connected at one end to the corner of the non-working end of the inside corner plastering body (1), and at the other end to the lower outer wall of the inside corner plastering handle (3).

[0025] As a further improvement of the present invention, a protective sleeve (31) is provided on the outer surface of the corner plastering handle (3). The protective sleeve (31) is a rubber sleeve, and several rubber protective protrusions with an integral structure are provided on the outer surface of the rubber sleeve.

[0026] As a further improvement of the present invention, the corner plastering handle (3) is a columnar component;

[0027] The mounting base (4) is a flat plate-shaped component. The fixed end of the flat plate-shaped component is vertically connected to the upper middle part of the corner plastering handle (3). The free end of the flat plate-shaped component is set as an arc segment.

[0028] As a further improvement to the present invention, the hanging hole (41) is an elliptical, triangular, circular or square structure, and the hanging hole (41) of this structure is opened on both sides of the free end edge of the mounting base (4).

[0029] The working principle is as follows: Before using the above-mentioned improved wall corner plastering tool, the construction personnel only need to manually or with appropriate handling equipment move the tool to the designated location for use.

[0030] When using it, it is used in conjunction with the wall inside corner (6) that needs to be constructed. During construction, the construction personnel first clean up the garbage or dirt at the wall inside corner (6) and wet it with water; then, the wall inside corner (6) is filled with mortar or fine stone concrete that needs to be smoothed, that is, the mortar or fine stone concrete is placed at the wall inside corner (6). Before the mortar or fine stone concrete initially sets, the operator holds the inside corner plastering handle (3) and places the inside corner plastering body (1) at the inside right corner, so that the inside corner plastering... Align the plastering squeegee (1) with the mortar or fine stone concrete at the inside corner (6) of the wall, and then pull the inside corner plastering handle (3) with a little force to scrape the mortar or fine stone concrete at the inside corner (6) of the wall into shape, forming a smooth mortar joint inside corner with rounded mortar and tight mortar. After the construction of the inside corner (6) of the wall is completed, conduct an inspection and acceptance. If it is qualified, proceed to the next process. Continue to construct the next inside corner (6) of the wall according to the above construction method.

[0031] Throughout the entire construction process described above, operators can check the leveling tool (5) to get timely feedback on the horizontal status, thereby helping them to operate stably. By maintaining the correct angle and position of the tool, operators can control it more easily, reduce human error, and make the plastering effect more uniform. The tool is kept in a stable horizontal position during the plastering process, and can be adjusted in time if it deviates. This allows operators to know the horizontal status of the tool at any time during the work process, avoiding the need to frequently check the horizontal status or readjust the position of the tool. Real-time monitoring of the horizontal status of the tool helps operators ensure that the tool remains horizontal when plastering inside corners, avoiding uneven plastering thickness due to tool tilt.

[0032] Finally, as time goes by, after all the construction work is completed, the construction workers only need to clean and repair this utility model, and then take it to the designated tool storage warehouse for storage by means of appropriate handling equipment or by manual labor for the next cycle of use. When storing, the tools are hung on the wall or tool rack through the hanging hole (41), so that the construction workers can take and adjust the tools more quickly, reduce unnecessary time waste, and improve construction efficiency.

[0033] The beneficial effects of this utility model compared with the prior art are:

[0034] 1. This utility model has a simple design structure, making it easy to hang, store, and preserve. It is easy to operate, significantly improving construction quality and efficiency, and is widely recognized by operators. It effectively improves the construction quality of inside corners, making the construction of mortar plastering at wall corners simple, convenient, and quick to form, with a smooth surface and beautiful corner shape, accelerating the construction progress and saving resources and costs. On the one hand, construction workers can hang tools on the wall or tool rack through the hanging holes, saving storage space and avoiding damage caused by tools being placed randomly. On the other hand, the hanging holes allow tools to be conveniently hung in the required position, allowing construction workers to quickly retrieve and adjust tools, reducing unnecessary time waste and improving construction efficiency.

[0035] 2. This utility model features a leveling device, specifically a universal level, which monitors the tool's horizontal position in real time. This helps construction workers ensure the tool remains level when plastering inside corners, preventing uneven plaster thickness caused by tool tilting. Especially on high walls or in complex corners, the use of a universal level significantly improves construction accuracy.

[0036] 3. The universal level of this invention can provide timely feedback on the horizontal status based on the swing and angle of the tool, thereby helping construction workers to operate stably. By maintaining the correct angle and position of the tool, construction workers can control the tool more easily, reduce human error, make the plastering effect more uniform, and ensure that the tool remains in a horizontal and stable state throughout the plastering process, and can be adjusted in time if deviation occurs;

[0037] 4. This utility model's universal level allows construction workers to monitor the horizontal status of tools at any time during work, avoiding the need for frequent checks or readjustments. This real-time monitoring improves construction efficiency, saves adjustment time, and reduces rework and waste.

[0038] 5. The corner plastering of this utility model requires extremely accurate tool angles and positions. A universal level helps construction workers maintain tool level at different angles and positions, ensuring that the plaster layer at each angle is uniform and meets standards. Especially for novice or less experienced construction workers, the universal level provides intuitive level indications, helping them more easily master the operating techniques. Frequent manual adjustments are unnecessary; the level's prompts allow for quick and effective tool position adjustments, reducing errors.

[0039] 6. Because the handle of the corner plastering tool is covered with a protective sleeve, this utility model can protect the operator's hands from wear and tear during long-term work, thus ensuring construction safety.

[0040] 7. The exterior of this utility model is coated with anti-rust paint and a waterproof layer, which can prevent rusting and extend the service life of the tool. It is environmentally friendly and saves resources. At the same time, the exterior of the tool is coated with a self-illuminating fluorescent material, which can clearly mark the location of the tool at night or in dark indoor or underground construction environments.

[0056] To make the technical means, inventive features, objectives, and effects of this utility model readily understandable, the technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0057] Example 1

[0058] like Figures 1 to 8 As shown, an improved wall corner plastering tool for building construction includes:

[0059] The inside corner plastering body 1 has a working end face that is used to contact the inside corner 6 of the wall and work together to complete the plastering work.

[0060] The handle reinforcing link 2 has one end connected to the lower middle part of the non-working end face of the corner plastering body 1, and the other end connected to the corner plastering handle 3.

[0061] The corner plastering handle 3 has a mounting base 4 extending from the middle of its upper end;

[0062] Mounting base 4, the upper center of mounting base 4 has a hanging hole 41 through the front and back sides for easy storage and hanging.

[0063] Furthermore, such as Figures 1 to 8 As shown, the inside corner plastering body 1 is composed of two plastering boards with the same shape and structure connected to each other, forming an angle of 90° between the two plastering boards.

[0064] Furthermore, the handle reinforcing link 2 is composed of two rod-shaped components of different lengths, wherein,

[0065] One end of a handle reinforcing link 2 is connected to the corner of the lower non-working end of the corner plastering body 1, and the other end is connected to the upper outer wall of the corner plastering handle 3.

[0066] Another handle reinforcing link 2 is connected at one end to the corner of the non-working end of the inside corner plastering body 1, and at the other end to the lower outer wall of the inside corner plastering handle 3.

[0067] In this utility model, the handle reinforcing link 2 is a steel bar.

[0068] Specifically, the corner plastering handle 3 is a columnar component;

[0069] The mounting base 4 is a flat plate-shaped component. The fixed end of the flat plate-shaped component is vertically connected to the upper middle part of the corner plastering handle 3, and the free end of the flat plate-shaped component is set as an arc segment.

[0070] Furthermore, the hanging hole 41 is elliptical, triangular, circular, or square in shape, and the hanging hole 41 of this structure is opened on both sides of the free end edge of the mounting base 4.

[0071] In this utility model, the hanging hole 41 can also be used to realize the use of ropes or wires to thread through multiple wall corner plastering tools of this utility model.

[0072] In the above embodiment 1, the construction is carried out in conjunction with the wall inside corner 6 that needs to be constructed. During construction, the construction personnel first clean up the garbage or dirt at the wall inside corner 6 and moisten it with water. Then, the mortar or fine stone concrete that needs to be smoothed is pre-filled at the wall inside corner 6. That is, the mortar or fine stone concrete is placed at the wall inside corner 6. Before the mortar or fine stone concrete initially sets, the operator holds the inside corner plastering handle 3 and places the inside corner plastering body 1 at the inside right angle, so that the inside corner plastering scraper 1 is aligned with the mortar or fine stone concrete at the wall inside corner 6. Then, the inside corner plastering handle 3 is pulled with a little force in one direction to scrape the mortar or fine stone concrete at the wall inside corner 6 into shape, forming a smooth mortar joint inside corner with a rounded mortar joint and tight mortar. After the construction of the wall inside corner 6 is completed, it is inspected and accepted. After passing the inspection, the next process is carried out. The construction of the next wall inside corner 6 is carried out according to the above construction method.

[0073] Finally, as time goes by, once all the construction work is completed, the construction workers only need to clean and repair the utility model, and then transport it to the designated tool storage warehouse for storage using appropriate handling equipment or manually for the next cycle of use. When storing, the tools can be hung on the wall or tool rack through the hanging hole 41, allowing the construction workers to retrieve and adjust the tools more quickly, reducing unnecessary time waste and improving construction efficiency.

[0074] Example 2

[0075] This embodiment 2 is the same as embodiment 1, except that it also includes a leveling tool 5, which is connected to the outer wall of the mounting base 4.

[0076] Specifically, the leveling tool 5 is a universal level.

[0077] In this embodiment, during use, the operator can check the leveling tool 5 for timely feedback on the horizontal status, thus helping the construction workers to operate stably. By maintaining the correct angle and position of the tool, the construction workers can more easily control the tool, reduce human error, and make the plastering effect more uniform. Furthermore, the tool is guaranteed to remain in a stable horizontal state throughout the plastering process, and any deviation can be adjusted promptly. This allows the construction workers to understand the tool's horizontal status at any time during work, avoiding the need for frequent checks or readjustments. Real-time monitoring of the tool's horizontal status helps the construction workers ensure that the tool remains horizontal when plastering inside corners, preventing uneven plaster layer thickness caused by tool tilting.

[0078] Other uses are the same as in Example 1, and will not be repeated here.

[0079] Example 3

[0080] This embodiment 3 is the same as embodiment 1 and embodiment 2, except that, as Figure 7 and Figure 8 The corner plastering body 1 is a one-piece molded fixing plate.

[0081] When using it, it is the same as in Examples 1 and 2, and will not be repeated here.

[0082] Example 4

[0083] This embodiment 4 is the same as embodiments 1 to 3, except that, as Figures 1 to 6 As shown, the inside corner plastering body 1 is a repairable board. The upper part of the repairable board is an L-shaped plate-like component formed by connecting several L-shaped inside corner plastering pieces 11 sequentially from top to bottom. A cutting edge 12 is provided between adjacent L-shaped inside corner plastering pieces 11.

[0084] In this invention, the cutting edge 12 is composed of a plurality of alternating broken segments and continuous segments. The cutting edge 12 is a discontinuous or continuous edge made by mechanical or laser means. The cutting edge 12 is in a sealed and airtight state, and the cutting edge 12 only breaks when subjected to external force.

[0085] In this embodiment 4, since a cutting edge 12 is provided between adjacent L-shaped corner trowels 11, when one of the L-shaped corner trowels 11 is worn or damaged during long-term use, seriously affecting its use, the operator needs to completely cut off and peel the damaged L-shaped corner trowel 11 or multiple L-shaped corner trowels 11 from the other remaining L-shaped corner trowels 11 into two parts, separating the damaged parts and leaving the intact L-shaped corner trowels 11 for continued use until they can no longer be used, at which point a new tool needs to be made or replaced.

[0086] Example 5

[0087] This embodiment 5 is the same as embodiments 1 to 4, except that a protective sleeve 31 is provided on the outer surface of the corner plastering handle 3. The protective sleeve 31 is a rubber sleeve, and several integrated rubber protective protrusions are provided on the outer surface of the rubber sleeve.

[0088] Specifically, the protective sleeve 31 is a rubber sleeve, and several integrated rubber protective protrusions are provided on the outer surface of the rubber sleeve. These rubber protective protrusions are granular or annular protrusions.

[0089] In this embodiment 4, since a protective sleeve 31 is provided on the hand-held part of the corner plastering handle 3, it can protect the operator's hands from wear and tear during long-term work, thus ensuring the safety of construction.

[0090] Other uses are the same as in other embodiments, and will not be repeated here.

[0091] Furthermore, from the inside out, injection molding layer, anti-rust layer, waterproof layer, and warning layer are sequentially provided on the outer surfaces of the corner plastering body 1, the handle reinforcing link 2, the corner plastering handle 3, and the mounting base 4. The warning layer is coated with fluorescent powder.

[0092] Specifically, a wear-resistant polymer material is injection molded onto the injection-molded layer; the anti-rust layer includes an epoxy zinc-rich primer and a chlorinated rubber topcoat, as well as an epoxy micaceous iron oxide intermediate coat located between the epoxy zinc-rich primer and the chlorinated rubber topcoat; the waterproof layer is a polyurethane waterproof coating; and the warning layer is a reflective warning tape, reflective film, or reflective paint of a single color or a mixture of multiple colors.

[0093] Meanwhile, in this utility model, all connections referred to are fixed connections, movable connections, or detachable connections. Among them, fixed connections are welded connections or directly processed into an integral structure; movable connections, detachable connections, or split structures are hinged connections, internal and external threaded connections, bayonet connections, plug-in sleeves, bolt assembly connections, or screw connections.

[0094] In summary, a more specific embodiment of this utility model is as follows:

[0095] Before using the above-mentioned plastering tool for right-angle wall construction, the construction personnel only need to manually or with appropriate handling equipment move the tool to the designated location for use.

[0096] When using it, it should be applied to the inside corner of the wall where the work is to be done.

[0097] The specific construction steps are as follows:

[0098] Step 1: During construction, the workers first clean up any trash or dirt in the six corners of the wall and then wet them with water.

[0099] Step 2: Fill the inside corner 6 of the wall with mortar or fine aggregate concrete that needs to be smoothed. That is, place the mortar or fine aggregate concrete at the inside corner 6 of the wall.

[0100] Step 3, as follows Figure 1 As shown, before the mortar or fine stone concrete initially sets, the operator holds the inside corner plastering handle 3, places the inside corner plastering body 1 at the inside right angle, aligns the inside corner plastering scraper 1 with the mortar or fine stone concrete at the inside corner 6 of the wall, and then pulls the inside corner plastering handle 3 with a little force in one direction to scrape the mortar or fine stone concrete at the inside corner 6 of the wall into shape, forming a smooth and consistent mortar joint inside corner, with the mortar joint rounded and the mortar tight;

[0101] Step 4: Operators can check the leveling tool 5 for timely feedback on the horizontal status, thus helping construction workers to operate stably. By maintaining the correct angle and position of the tool, construction workers can more easily control it, reduce human error, and achieve a more uniform plastering effect. Furthermore, ensuring the tool remains level and stable throughout the plastering process allows for timely adjustments in case of deviation. This allows construction workers to monitor the tool's horizontal status at any time during work, avoiding the need for frequent checks or readjustments. Real-time monitoring of the tool's horizontal status helps construction workers ensure that the tool remains level when plastering inside corners, preventing uneven plaster layer thickness caused by tool tilting.

[0102] Step 5: After the construction of the wall inside corner 6 is completed, conduct an inspection and acceptance. If it passes the inspection, proceed to the next process. Continue to construct the next wall inside corner 6 according to the above construction method.

[0103] Step 6: As time goes by, after all the construction work is completed, the construction workers only need to clean and repair this utility model, and then take it to the designated tool storage warehouse for storage by means of appropriate handling equipment or by manual labor for the next cycle of use. When storing, the tools are hung on the wall or tool rack through the hanging hole 41, so that the construction workers can retrieve and adjust the tools more quickly, reduce unnecessary time waste, and improve construction efficiency.

[0104] During the above construction process, if the mortar or fine stone concrete at the 6th corner of the wall cannot be formed in one application, the construction workers can continue to repeatedly trowel and press the mortar or fine stone concrete at the 6th corner of the wall to form the desired shape.

[0105] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
