Description

Technical Field

[0001] The utility model relates to the technical field of coating application devices, in particular to a coating device for waterproof coating of bolt holes on exterior walls of buildings. Background Art

[0002] During the meticulous construction of building exterior walls, ensuring secure connections between structural components is crucial, often relying on the installation of fasteners such as screws and expansion bolts. However, this step inevitably requires precise drilling of holes in the solid wall to accommodate these connectors, which inevitably leaves numerous tiny bolt holes. While these holes significantly contribute to structural stability, they also pose a potential risk to the overall aesthetics and functionality of the building's exterior walls. In particular, they weaken the wall's integrity and reduce its waterproofing and anti-seepage properties, posing a significant challenge for building areas requiring stringent waterproofing requirements, such as basements and bathroom exteriors.

[0003] To address this issue, traditional methods employ a dual strategy of sealing and coating. First, the bolt holes are sealed with sealing materials such as rubber plugs and specialized sealing glue to initially isolate them from moisture. Workers then carry heavy buckets of paint and repeatedly dip a brush into the waterproofing paint, meticulously applying it around the bolt holes and onto the surface until the holes are completely covered and filled, enhancing the waterproofing effect. This process is not only labor-intensive and inefficient, but also relies on the workers' manual skill and patience, making it difficult to ensure that every hole is treated evenly and effectively.

[0004] To improve this situation, technological innovation has brought about a more convenient and efficient solution: the integrated paint system. This system cleverly integrates the brush and the paint storage container. The brush head is covered with fine holes and driven by a precision piston pump built into the rear end of the paint storage container, achieving automatic paint supply and uniform extrusion. This design greatly reduces the burden on workers, eliminating the need for frequent dipping and carrying heavy paint buckets, significantly improving work efficiency and painting quality.

[0005] However, while this innovative technology offers numerous advantages, its internal mechanisms also present new challenges. In particular, piston pumps operate in environments where direct contact with paint can lead to the accumulation of residual paint inside the pump body. Over time, this residual paint can dry out and hinder the smooth movement of the piston, affecting the proper supply of paint and potentially damaging mechanical components, shortening the life of the equipment. Utility Model Content

[0006] In order to solve the technical problem in the prior art that residual paint is easily left in the piston pump of the waterproof paint coating device for bolt holes in building exterior walls, affecting the smooth movement of the piston and the normal supply of paint, the utility model provides a waterproof paint coating device for bolt holes in building exterior walls.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A device for applying waterproof coating to bolt holes on building exterior walls includes a feed cylinder, a circular brush device is installed at the front end opening of the feed cylinder, the rear end of the feed cylinder is closed, the outer wall of the feed cylinder is connected to a feeding device, the feeding device includes a pressure tank, the pressure tank is provided with a sealing cover, the interior of the pressure tank is connected to the feed cylinder, and the interior of the pressure tank is connected to one end of a delivery pipe; the outer wall of the feed cylinder is connected to a gas boosting mechanism, the gas boosting mechanism includes a gas output pipe, and the gas output pipe is connected to the other end of the delivery pipe.

[0009] With the above-mentioned structural solution, before construction, waterproof filler is filled into the bolt hole. First, the sealing cover is opened, and a certain amount of waterproof coating is poured into the pressure tank. Then, the sealing cover is closed, and the gas boost mechanism is turned on for boosting. The airflow flows along the gas output pipe to the delivery pipe. As the airflow continues to enter, the pressure in the pressure tank gradually increases, squeezing the waterproof coating into the feed barrel. The waterproof coating in the feed barrel is squeezed out from the brush under the action of air pressure, so that the bolt hole can be filled and leveled with the brush so that the bolt hole is flush with the wall. After the construction is completed, a certain amount of thinner can be injected into the pressure tank, and the boosting is started. The thinner enters the pressure tank from the delivery pipe and is then squeezed out from one end of the brush on the feed barrel, thereby flushing the entire structure. After the flushing is completed, the boosting is stopped and the ball valve switch is closed for convenience next time use.

[0010] As described above, the present invention uses a gas boosting mechanism to boost pressure, and the gas boosting mechanism has no contact with the waterproof coating and is not easily clogged. The present invention has high construction efficiency and is easy to flush without leaving residue.

[0011] As a preferred implementation of a device for applying waterproof coating to bolt holes on exterior walls of buildings, a pressure gauge is installed on the delivery pipe.

[0012] With the above structural solution, during the application of waterproof coating, the pressure gauge is observed at any time to read the pressure value. If the pressure value is too high, the pressurization is stopped. If the pressure value is too low, the pressurization is continued to achieve the ideal discharge effect.

[0013] As a preferred implementation of a device for applying waterproof coating to bolt holes on exterior walls of buildings, a ball valve switch is provided between the pressure tank and the feed cylinder.

[0014] With this structural solution, if the construction process is stopped midway, the ball valve can be closed to avoid wasting waterproof coating. During the construction process, the flow rate of the waterproof coating can be controlled by adjusting the opening and closing degree of the ball valve, thereby controlling the discharge speed of the waterproof coating.

[0015] As a preferred implementation method of a device for applying waterproof paint to bolt holes on exterior walls of buildings, the front end outer wall of the feed cylinder is provided with an external thread, and the brush device includes a circular metal plate, which is a hollow shell with a cavity inside. A connecting port is provided on the end face of one end of the metal plate, which is connected to the internal cavity of the metal plate, and an internal thread is provided on the inner wall of the connecting port, which is connected to the front end thread of the feed cylinder; the end face of the other end of the metal plate is connected to a brush body and the end face is provided with several discharge ports, the brush body covers the end face of the metal plate, and the discharge port is connected to the internal cavity of the metal plate.

[0016] By adopting the above structural solution, by replacing metal plates of different diameters and keeping the diameter of the connecting port on the metal plate unchanged, the waterproof coating construction of bolt holes of different diameters can be realized.

[0017] As a preferred implementation method of a device for applying waterproof coating to bolt holes on building exterior walls, the side wall of the rear end of the feed cylinder extends backward along the axial direction of the feed cylinder to form an extension cylinder, the gas boosting mechanism is connected to the side wall of the extension cylinder, and the gas output pipe extends into the extension cylinder.

[0018] By adopting the above structural solution, the extension tube can protect the structure of the connection point between the gas output pipe and the delivery pipe.

[0019] As an optimal implementation method of a device for applying waterproof coating to bolt holes on exterior walls of buildings, a gas boosting mechanism includes a boosting pump and a boosting motor; the feed barrel is connected to an electric wrench, the electric wrench is provided with a handle and a switch button, and the output shaft of the electric wrench is connected to the motor shaft of the boosting motor through a transmission member.

[0020] The beneficial effects of the utility model include:

[0021] Before construction, fill the bolt hole with waterproof filler. First, open the sealing cover and pour a certain amount of waterproof coating into the pressure tank. Then, cover the sealing cover and turn on the gas booster to boost the pressure. The airflow flows along the gas output pipe to the delivery pipe. As the airflow continues to enter, the pressure in the pressure tank gradually increases, squeezing the waterproof coating into the feed tube. The waterproof coating in the feed tube is squeezed out from the brush under the action of air pressure. Thus, the brush can be used to smear and fill the bolt hole so that the bolt hole is flush with the wall. After the construction is completed, a certain amount of thinner can be injected into the pressure tank and the boosting is started. The thinner enters the pressure tank from the delivery pipe and is then squeezed out from one end of the brush on the feed tube. Thus, the entire structure can be flushed. After the flushing is completed, the boosting is stopped and the ball valve switch is closed for easy use next time. The present application uses a gas booster to boost the pressure. The gas booster has no contact with the waterproof coating and is not easily clogged. The present application has high construction efficiency and is easy to flush, and is not prone to residue.

[0031] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0032] Reference Figure 1-6 , this embodiment proposes a device for applying waterproof coating to bolt holes on exterior walls of buildings, comprising a feeding cylinder 1, a circular brush device 2 being installed at the front end opening of the feeding cylinder 1, an outer wall of the front end of the feeding cylinder 1 being provided with an external thread, and the brush device 2 comprising a circular metal plate 21, the metal plate 21 being a hollow shell with a cavity provided therein, a connecting port being provided at the end face of one end of the metal plate 21, the connecting port being communicated with the internal cavity of the metal plate 21, the inner wall of the connecting port being provided with an internal thread, and the connecting port being threadedly connected to the front end of the feeding cylinder 1; a brush body 22 being connected to the end face of the other end of the metal plate 21 and the end face being provided with a plurality of discharge ports, the brush body 22 covering the end face of the metal plate 21, the brush body 22 being 2 mm higher than the end face of the metal plate 21, and the discharge port being communicated with the internal cavity of the metal plate 21.

[0033] The rear end of the feed barrel 1 is sealed, and the top of its outer wall is connected to a feeding device. This device includes a pressure tank 3 equipped with a sealing cap 4. The interior of the pressure tank 3 communicates with the feed barrel 1. A manually operated ball valve 7 is installed between the pressure tank 3 and the feed barrel 1. The interior of the pressure tank 3 communicates with one end of a vertically mounted delivery pipe 5, which is equipped with a pressure gauge 6. The sidewall of the rear end of the feed barrel 1 extends rearward along the axial direction of the feed barrel 1 to form an extension barrel 10. A gas booster mechanism 9 is connected to the bottom of the sidewall of the extension barrel 10. The gas booster mechanism 9 includes a gas output pipe. Both the gas output pipe and the delivery pipe 5 extend into the extension barrel 10, and the gas output pipe communicates with the other end of the delivery pipe 5 within the extension barrel 10. A one-way valve can also be installed on the delivery pipe 5 to prevent the waterproof coating from flowing back into the gas booster mechanism 9.

[0034] The gas boosting mechanism 9 includes a boosting pump 91 and a boosting motor 92; the feed barrel 1 is connected to the electric wrench 8, which is provided with a handle 81 and a switch button 82, and the output shaft of the electric wrench 8 is connected to the motor shaft of the boosting motor 92 through a transmission member.

[0035] The working principle of this embodiment is:

[0036] Before construction, fill the bolt hole with waterproof filler. First, open the sealing cover 4 and pour a certain amount of waterproof coating into the pressure tank 3. Then cover the sealing cover 4 and open the ball valve switch 7. The staff holds the electric wrench 8, holds the handle 81, presses the switch button 82, drives the booster motor 92 to work, and pressurizes the booster pump 91. The air flow flows along the gas output pipe to the delivery pipe 5. As the air flow continues to enter, the pressure in the pressure tank 3 gradually increases, and the waterproof coating is squeezed into the feed barrel 1. The waterproof coating in the feed barrel 1 is squeezed out from several discharge ports of the brush 2 under the action of air pressure. Therefore, the brush 2 can be used to smear and fill the bolt hole so that the hole of the bolt hole is flush with the wall.

[0037] If the application process is interrupted, the ball valve switch 7 can be closed to avoid wasting the waterproof coating. The flow rate of the waterproof coating can also be controlled by adjusting the degree of opening and closing of the ball valve switch 7, thereby controlling the discharge rate of the waterproof coating. During the application of the waterproof coating, the pressure gauge 6 is constantly monitored to read the pressure value. If the pressure value is too high, the pressure is stopped. If the pressure value is too low, the pressure is continued to achieve the desired discharge effect.

[0038] By replacing the metal plates 21 with different diameters and keeping the diameter of the connecting opening on the metal plates 21 unchanged, the waterproof coating construction of bolt holes with different diameters can be achieved.

[0039] After the construction is completed, a certain amount of thin material can be injected into the pressure tank 3, the ball valve switch 7 is opened, and the pressurization is started. The thin material enters the pressure tank 3 from the conveying pipe 5, and is then squeezed out from one end of the brush device 2 on the feeding barrel 1, thereby flushing the entire structure. After the flushing is completed, the pressurization is stopped and the ball valve switch 7 is closed for convenience next time use.

[0040] In this embodiment, the transmission member includes a transmission shaft extending into the extension tube 10 and also includes a bevel gear transmission group or a belt transmission structure to realize transmission between the transmission shaft and the motor shaft of the boost motor 92.

[0041] In other embodiments, the gas boosting mechanism 9 may also be a gas booster commonly used in the prior art. The gas booster is provided with an independent switch, and the power comes from a power supply or a battery, so there is no need to provide an electric wrench 8.

[0042] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
