Description

Technical Field

[0001] The invention belongs to the technical field of the construction of the dividing joints of exterior wall coatings, and particularly relates to a device for arranging the dividing joints of exterior wall coatings. Background Art

[0002] In the traditional construction of the dividing joints of exterior wall coatings, artificial laying of imitation brick tapes one by one is adopted, which has the following defects: 1. Low efficiency: Manual operation is time-consuming and laborious, and the daily construction area is less than 100 ㎡, which is difficult to meet the requirements of large-scale projects.

[0003] 2. Poor precision: The error of the spacing of the dividing joints often reaches ±5 mm, resulting in a messy texture on the wall surface after painting.

[0004] 3. High cost: The rework rate is about 15%, increasing the material and labor costs.

[0005] 4. Poor adaptability: It is difficult to manually align complex wall surfaces (such as arc-shaped and special-shaped structures).

[0006] A rapid wall paint dividing joint construction device disclosed in a Chinese utility model patent with an authorization announcement date of October 13, 2023 and an authorization announcement number of CN219825989U includes a right-angle scale plate and a plurality of U-shaped cards. Scale lines are provided on the right-angle scale plate. Each U-shaped card is slidably sleeved on the right-angle scale plate and slid to adjust the position. A fixing rod is installed on the U-shaped card, a gear turntable is installed on the fixing rod, a tape roll is wound on the gear turntable. The fixing rods on each U-shaped card are parallel to each other, the planes where each gear turntable is located are parallel to each other, and the fixing rod is vertically connected to the right-angle scale plate.

[0007] The above rapid wall paint dividing joint construction device can quickly complete the production of the dividing joints on the wall surface, but there are the following problems: 1. With the movement of the operator or under the interference of the wind, there are several tape rolls, and each tape roll may have different movement directions, some rotate forward and some rotate backward. The backward rotation will cause the tape to slack and stick together, affecting the work efficiency and quality; 2. The tape roll can rotate freely. When the operation is completed and turnover is required, the tape roll will still rotate arbitrarily, resulting in the tape sticking together and wasting materials.

[0008] Therefore, how to effectively solve the problems of low construction efficiency and quality of wall paint dividing joints and material waste is a technical problem to be solved urgently. Summary of the Invention

[0009] In view of the above deficiencies in the background art, the present invention proposes a device for arranging the dividing joints of exterior wall coatings, which solves the problems of low construction efficiency and quality of wall paint dividing joints and material waste.

[0010] The technical solution of this application is as follows: A device for arranging dividing joints of exterior wall coatings, comprising a plurality of tape arranging units detachably connected to a scale. The tape arranging units include an anti-reverse component for preventing the tape reel from rotating in reverse and a limiting component for restricting the continuous rotation of the tape reel when the construction is paused or completed. Through the scale provided by the present invention for reference positioning, and in cooperation with a plurality of detachably connected tape arranging units, multiple dividing joints can be quickly and accurately arranged at equal intervals on the wall surface without arranging them one by one, avoiding manual measurement errors, significantly improving the construction efficiency, and being convenient to operate and accurately positioned; the anti-reverse component prevents the tape reel from rewinding, ensuring that the tape remains taut after being pulled out, avoiding paste skew or shedding caused by tape slack, especially suitable for high-altitude operations; when the construction is completed and the device needs to be turned around, the limiting component can lock the rotation of the tape reel to prevent the tape reel from rotating randomly, resulting in tape adhesion. At the same time, it is also convenient for construction workers to pause, adjust or cut the tape, avoiding waste or adhesion caused by excessive pulling of the tape; multiple tape arranging units can be flexibly installed at different positions on the scale to adapt to the requirements of dividing joints of different widths and complex patterns, such as cross joints, diamond joints, etc., without replacing tools, with a wide application range and high flexibility.

[0011] Further, the tape arranging unit includes a clamp that is slidably engaged with the scale, and the relative position between the clamp and the scale is positioned by a positioning member. A marking window for viewing the scale is provided on the side surface of the clamp.

[0012] Further, the clamp is connected to a support plate. A turntable for installing the tape reel and a roller for guiding the extended tape are rotatably connected to the support plate. The anti-reverse component is arranged inside the turntable, and the limiting component is arranged on the turntable.

[0013] Further, the support plate includes a connected horizontal plate and inclined plate, and an obtuse angle is formed between the horizontal plate and the inclined plate.

[0014] Further, baffles for preventing the tape from falling off are provided at both the top and bottom of the roller, which can limit the tape to adhere to the roller and prevent the tape from slipping out of the roller.

[0015] Further, the anti-reverse component includes a ratchet rotatably connected to the support plate and a pawl hinged to the support plate. A spring is arranged between the pawl and the support plate, and the pawl abuts against the ratchet teeth on the ratchet under the action of the spring. A connecting rod for synchronous rotation is connected between the ratchet and the turntable.

[0016] Further, a tray for storing the anti-reverse component is arranged between the support plate and the ratchet, and the tray blocks the bottom of the tape reel.

[0017] Further, the limiting component includes a rod arranged on the top of the turntable. A chute is arranged on the lower surface of the rod, and a pressing block for pressing on the outer periphery of the tape reel is slidably fitted in the chute. The pressing block is positioned by the frictional force with the chute.

[0018] Further, the end of the rod is connected to the center of the turntable. The length of the rod is greater than the radius or diameter of the tape reel. The pressing block presses on the outer periphery of the tape reel, which can lock the rotation of the tape reel, facilitating the construction personnel to pause for adjustment or cut the tape, and avoiding waste or adhesion caused by excessive pulling out of the tape. At the same time, when the operation is completed and the device needs to be turned around, the tape reel will still rotate arbitrarily, resulting in tape adhesion and material waste. By pressing the pressing block on the outer periphery of the tape reel, the tape reel can be stopped from rotating.

[0019] Further, a level is arranged on the scale for ensuring the horizontal reference during measurement or assisting in leveling the device. A hook for temporary hanging is arranged on the top of the scale, which can be temporarily hung somewhere during high-altitude operation for convenient use.

[0020] The specific beneficial effects of the present invention include: 1. The present invention provides a reference positioning through the scale, and cooperates with a plurality of tape layout units that can be detachably connected, which can quickly and accurately arrange multiple dividing seams at equal intervals on the wall surface without arranging them one by one, avoiding manual measurement errors, significantly improving the construction efficiency, and being convenient to operate and accurately positioned. 2. The anti-reverse component prevents the tape reel from rewinding, ensuring that the tape remains taut after being pulled out, and avoiding sticking skew or falling off caused by tape slack, especially suitable for high-altitude operations. 3. When the construction is completed and the device needs to be turned around, the limiting component can lock the rotation of the tape reel, preventing the tape reel from rotating arbitrarily, resulting in tape adhesion, and at the same time, it is also convenient for the construction personnel to pause for adjustment or cut the tape, avoiding waste or adhesion caused by excessive pulling out of the tape. 4. Multiple tape layout units can be flexibly installed at different positions on the scale to adapt to the requirements of dividing seams with different widths and complex patterns, such as cross seams, diamond seams, etc. There is no need to replace tools, and the application range is wide and the flexibility is high.

[0024] 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.

[0025] Embodiment 1. A device for arranging partition joints of exterior wall coatings includes a plurality of tape arranging units 2 detachably connected to a scale 1. The tape arranging unit 2 includes an anti-reverse component 4 for preventing the tape reel 3 from rotating in reverse and a limiting component 5 for pausing or restricting the continuous rotation of the tape reel 3 when the construction is completed. The present invention provides a reference positioning through the scale, and with a plurality of detachably connected tape arranging units 2, it can quickly and accurately arrange multiple partition joints at equal intervals on the wall surface without arranging them one by one, avoiding manual measurement errors, significantly improving the construction efficiency, and being convenient to operate and accurately positioned; the anti-reverse component 4 prevents the tape from rewinding, ensuring that the tape remains taut after being pulled out, avoiding paste skew or detachment caused by tape slack, especially suitable for high-altitude operations; when the construction is completed and the device needs to be transferred, the limiting component 5 can lock the rotation of the tape reel to prevent the tape reel from rotating randomly, resulting in tape adhesion, and at the same time, it is also convenient for construction workers to pause, adjust or cut the tape, avoiding waste or adhesion caused by excessive pulling of the tape; multiple tape arranging units 2 can be flexibly installed at different positions on the scale 1 to adapt to the requirements of partition joints of different widths and complex patterns, such as cross joints, diamond joints, etc., without changing tools, with a wide application range and high flexibility.

[0026] Specifically, the scale 1 is made of 6061-T6 aluminum alloy, with an anodized surface treatment, strong weather resistance, high strength and rigidity, and at the same time, it is light in weight, facilitating the operation and carrying of construction workers.

[0027] On the basis of the above embodiment, the tape arranging unit 2 includes a clamp 21 that is slidably matched with the scale 1, and the relative position between the clamp 21 and the scale 1 is positioned by a positioning member 6. The fixed position of the clamp 21 can be adjusted arbitrarily according to the required position, and the spacing of the tape partition joints can be set quickly and accurately, with flexible application. Each scale is carefully designed to ensure the uniformity of the partition joint spacing. During adjustment, construction workers can accurately position through the clamp 21, and once the clamp 21 is locked, it will not loosen, avoiding inaccurate partition joints caused by equipment movement. At the same time, multiple tape arranging units 2 can be flexibly installed at different positions on the scale 1 to adapt to the requirements of partition joints of different widths and complex patterns, such as cross joints, diamond joints, etc., without changing tools, with a wide application range and high flexibility.

[0028] Specifically, a marking window 22 for viewing the scale is provided on the side surface of the clamp 21. When the operator holds the device, the face is exactly facing the side surface with the scale, and the marking window 22 is also provided on this side surface for easy observation of the required information at any time.

[0029] On the basis of the above-described embodiments, the hoop 21 is connected to a support plate 23. Rotatably connected to the support plate 23 are a turntable 24 for mounting the tape reel 3 and a roller 25 for guiding the extended tape. The turntable 24 and the roller 25 are both connected to the support plate 23 through rotating shafts, and the turntable 24 and the roller 25 rotate 360 degrees respectively around their own rotating shafts. The anti-reverse component 4 is arranged inside the turntable 24. The tape reel 3 rotates as the present invention moves. As shown in Figure 1 shown, when the device moves to the right, the tape reel 3 rotates clockwise. The anti-reverse component 4 prevents the tape reel 3 from rotating counterclockwise, avoiding the situation that when the device stops moving, the tape reel 3 still has inertia and continues to rotate, resulting in extra tape, and causing the extra tape to stick together, affecting subsequent construction. A limiting component 5 is arranged on the turntable 24. The limiting component 5 includes a rod member 51 arranged on the top of the turntable 24. A chute is arranged on the lower surface of the rod member 51. A pressing block 52 for pressing against the outer circumference of the tape reel 3 is in sliding fit with the chute. The pressing block 52 is positioned by the friction force with the chute. The pressing block 52 is stuck on the outer circumference of the tape reel 3 to prevent the tape reel 3 from falling off or being blown off by the wind.

[0030] Specifically, the roller 25 adopts a 304 stainless steel bearing, and the rotational resistance ≤ 0.1 N·m, supporting the smooth release of the tape; the central shaft of the roller 25 is connected to the support plate 23 through an M6 screw and can be quickly disassembled and replaced. The tape roller has a special bearing design, which can effectively reduce friction, ensure the smooth unfolding of the tape, reduce resistance, and improve efficiency.

[0031] On the basis of the above-described embodiments, the support plate 23 includes a connected horizontal plate and inclined plate. An obtuse angle, which can be 145°, is formed between the horizontal plate and the inclined plate. The roller 25 is connected to the end of the inclined plate, which can form a stable support on the wall surface, avoiding unevenness or misalignment when the tape is wound. A scale and positioning points are arranged on the support plate 23, which can help construction workers accurately position the tape.

[0032] On the basis of the above-described embodiments, baffles 26 for preventing the tape from falling off are arranged at both the top and the bottom of the roller 25, which can limit the tape to adhere to the roller 25 and prevent the tape from slipping out of the roller 25.

[0033] On the basis of the above-described embodiments, the anti-reverse component 4 includes a ratchet wheel 41 rotatably connected to the support plate 23 and a pawl 43 hinged to the support plate 23. A spring 42 is arranged between the pawl 43 and the support plate 23. The pawl 43 abuts against the ratchet teeth on the ratchet wheel 41 under the action of the spring 42. The ratchet wheel 41 is in blocking cooperation with the pawl 43 through the spring 42. Through the engagement and disengagement of the pawl 43 and the ratchet wheel 41, the continuous movement of the driving member is converted into the one-way step movement of the driven member. A connecting rod 29 for synchronous rotation is connected between the ratchet wheel 41 and the turntable 24. As shown inFigure 4 As shown in the figure, two insertion holes are provided on the ratchet wheel 41. Two connecting rods 29 are connected inside the turntable 24. The connecting rods 29 are inserted into the insertion holes. When the tape reel 3 rotates, the turntable 24 is driven to rotate, and then the ratchet wheel 41 is further driven to rotate in the same direction. When a force for reverse rotation is generated, the pawl 43 blocks the ratchet wheel 41 from rotating in the reverse direction to ensure that the ratchet wheel 41 rotates along the direction of construction movement of the tape reel 3.

[0034] On the basis of the above embodiment, a tray 28 for accommodating the anti-reverse assembly 4 is provided between the support plate 23 and the ratchet wheel 41. The tray 28 blocks the bottom of the tape reel 3. The ratchet wheel 41, the pawl 43, and the spring 42 are all arranged in the tray 28, which can play a certain protective role. The tray 28 is fixedly connected to the support plate 23. The tray 28 blocks the bottom of the tape reel 3, playing a supporting role for the tape reel 3 and facilitating the cooperation between the tape and the roller 25.

[0035] On the basis of the above embodiment, the end of the rod member 51 is connected to the center of the turntable 24, and the length of the rod member 51 is greater than the radius of the tape reel 3. As Figure 5 shown, the pressing block 52 presses on the outer periphery of the tape reel 3 through a single point, which can lock the rotation of the tape reel 3, facilitating the construction personnel to pause, adjust or cut the tape, avoiding waste or adhesion caused by excessive pulling out of the tape; at the same time, when the operation is completed and turnover is required, the tape roll will still rotate arbitrarily, resulting in tape adhesion and material waste. By pressing the pressing block 52 on the outer periphery of the tape reel 3, the rotation of the tape reel 3 can be stopped.

[0036] On the basis of the above embodiment, a level 11 is provided on the scale 1 to ensure the horizontal reference during measurement or assist in leveling the equipment.

[0037] On the basis of the above embodiment, a hook 12 for temporary hanging is provided at the top of the scale 1, which can be temporarily hung somewhere during high-altitude operation for convenient use.

[0038] All components of this tool are made of weather-resistant materials that are waterproof and corrosion-resistant, and can meet the construction requirements under different weather conditions.

[0039] The working principle of the present invention is as follows: 1. Installation and adjustment: The construction personnel set the spacing of the dividing joints according to the size and requirements of the wall surface, fix the positions of the respective clamps 21, and can adjust the heights of the respective clamps 21 according to different wall heights to ensure that the tool can adapt to different construction environments.

[0040] 2. Tape placement: Clamp the tape reel 3 onto the turntable 24. Then extend one side of the tape to the pulley 25, unfold the tape and adhere it to the wall surface. Next, operate the tool to ensure the tape unfolds smoothly on the wall surface, avoiding wrinkles, twists or unevenness.

[0041] 3. Complete the layout of the dividing joints: After the tool completes the layout of one dividing joint, the construction worker only needs to easily push the tool to the next section, readjust the spacing of the dividing joints, and then continue working, which greatly improves the construction efficiency.

[0042] The usage steps of the present invention are as follows: First, fix the tape reel 3 to the turntable 24. Then fix each clamp 21 and the scale 1 according to the required spacing, and guide the tape to be laid along the outer wall surface, sliding smoothly to avoid the tape being twisted or not sliding smoothly. Observe the spirit level 11 at all times during the laying process.

[0043] Embodiment 2, as a preferred embodiment, is different from Embodiment 1 in that the limiting component 5 includes a rod member 51 disposed on the top of the turntable 24. A chute is provided on the lower surface of the rod member 51, and a pressing block 52 for pressing against the outer periphery of the tape reel 3 is slidably engaged with the chute. The pressing block 52 is positioned by the frictional force between it and the chute. The pressing block 52 is stuck on the outer periphery of the tape reel 3 to prevent the tape reel 3 from falling or being blown off. As Figure 6 shown, the length of the rod member 51 is greater than the diameter of the tape reel 3. The middle of the rod member 51 is connected to the center of the turntable 24. A pressing block 52 is provided at each end of the rod member 51. The two pressing blocks 52 press against the outer periphery of the tape reel 3, which can lock the rotation of the tape reel 3, facilitating the construction worker to pause, adjust or cut the tape, and avoiding waste or adhesion caused by excessive pulling out of the tape. At the same time, when the operation is completed and turnover is required, the tape roll will still rotate arbitrarily, resulting in tape adhesion and material waste. By pressing the pressing block 52 against the outer periphery of the tape reel 3, the rotation of the tape reel 3 can be stopped.

[0044] The details not described in the present invention are all well-known conventional technical means in the art.

[0045] The above content shows and describes the basic principles, main features and beneficial effects of the present invention. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
