Description

Technical Field

[0002] With the vigorous development of the construction industry, the process of urbanization has been accelerated, and more and more high-rise buildings have sprung up. However, after the wall supports of the attached lifting scaffolding and cantilever scaffolding used in the construction of high-rise buildings are removed, screw holes are left. The risk of water seepage in the exterior wall here has always troubled many owners.

[0003] In actual projects, the common method for plugging the screw holes on the exterior walls is to plug the screw holes with plugging materials, and then apply a layer of waterproof paint or waterproof mortar on the exterior of the exterior wall. Since the exterior wall is often directly painted with a brush during the painting process, when the amount of paint is small, it is easy to cause uneven and incomplete application of the waterproof paint (waterproof mortar), thus failing to achieve the waterproof effect. If too much paint is applied, it is easy to cause material waste and pollute the exterior wall.

[0004] Therefore, it is necessary to use a more effective portable painting device for painting after the screw holes in the exterior wall are sealed. Summary of the invention

[0045] Preferably, the double-layer material cavity 1 is a columnar structure, including a first cavity 101 and a second cavity 102 , wherein the first cavity 101 and the second cavity 102 are coaxially arranged, and the first cavity 101 is arranged around the outer side of the second cavity 102 .

[0046] The feeding unit is connected to the first cavity 101 via the arc tube 14 , and is used to provide sealing materials (waterproof coating, waterproof mortar, etc.) to the first cavity 101 .

[0047] The smearing unit is disposed in the second cavity 102 and can move along the axial direction of the second cavity 102 .

[0048] The bottom of the first cavity 101 is provided with a plurality of discharge ports 13 facing the second cavity 102 for conveying the material in the first cavity 101 to the bottom of the second cavity 102. The coating unit pushes the material output through the discharge ports 13 to the external wall opening to be processed and completes the coating operation.

[0049] Preferably, a trumpet-shaped opening is provided at the bottom end of the second cavity 102, and the wall surfaces of the second cavity 102 from the top end to the bottom end are sequentially a first vertical cylindrical surface 102a, a trumpet-shaped enlarged inclined surface 102b, and a second vertical cylindrical surface 102c; the discharge port 13 is arranged on the second vertical cylindrical surface 102c.

[0051] Furthermore, when the rubber plug 5 is close to the trumpet-shaped expanded slope 102b, the discharge port 13 can transport materials to the surface of the rubber plug 5. When the surface of the rubber plug 5 receives enough materials, the grip plate 3 can push the rubber plug 5 to push the corresponding materials to the external wall hole to be processed.

[0052] Furthermore, the surface of the rubber plug 5 is provided with a plurality of bristles 6 for applying the waterproof coating to the outer wall opening. By rotating the gripping plate 3, the bristles 6 are applied to the outer wall opening surface for waterproof coating, ensuring uniform coating and forming a pancake-shaped pattern, which is both beautiful and material-saving. Furthermore, when the gripping plate 3 is rotated to make the bristles 6 extend out of the first cavity 101, the cylindrical side surface 501 at the bottom end of the rubber plug 5 completes the sealing of the discharge port 13.

[0053] Preferably, a cross fixing frame 8 is provided in the second cavity 102, and the transmission rod 4 is arranged to pass through the central ring of the cross fixing frame 8. One end of the cross fixing frame 8 is connected to the inner wall of the device, and the other end is connected to the outer side of the central ring. The inner diameter of the central ring is slightly larger than the outer diameter of the transmission rod 4, so that the transmission rod 4 can pass through the ring freely, thereby ensuring that the entire transmission rod 4 is vertical.

[0054] Preferably, the top of the double-layer material chamber 1 is a solid barrel wall 2, and the solid barrel wall 2 is provided with openings. Specifically, the solid barrel wall 2 has four elliptical holes around it, which can reduce weight and facilitate carrying and use. A barrel support 7 is provided on the outside of the solid barrel wall 2. The entire barrel support 7 is an arc-shaped structure and can be used to lift the entire device. During the painting of the external wall opening, the operator can use the barrel support 7 to place the entire device horizontally and close to the external wall opening to achieve painting of the opening.

[0055] Preferably, the feeding unit comprises: a hopper barrel 9 , which is connected to the first cavity 101 via an arc-shaped tube 14 ; and a valve body structure is provided on the arc-shaped tube 14 for completing the conduction control of the arc-shaped tube 14 .

[0056] Preferably, the feeding unit further comprises a rubber airbag 17, a metal cover 15 is provided at the top of the hopper barrel 9, and the rubber airbag 17 is connected to the opening of the metal cover 15 via a rubber tube 16, forming a simple pressurization system, which facilitates the discharge of the waterproof mortar (waterproof coating) in the cavity along the discharge port 13. For example, by squeezing the rubber airbag 17, the material in the hopper barrel 9 is pumped out, and the material is output through the discharge port 13 under air pressure.

[0057] Preferably, the valve body structure arranged on the arc tube 14 includes: a valve card base 10, a bolt 11 and an interface plate 12. The arc tube 14 is arranged to penetrate the valve card base 10. The interface plate can be plugged in and out of the valve card base 10, and the flow cross-section of the arc tube 14 can be controlled by the insertion depth. The bolt 11 is used to fix the position of the interface plate; the interface plate 12 can change the effective inner diameter of the arc tube 14 by its cross-sectional position, thereby controlling the filling speed of the hopper barrel 9 and preventing material backflow during formal operation.

[0058] During construction, after the external wall opening is filled with the plugging material, the prepared waterproof coating (waterproof mortar) is poured into the hopper barrel 9 and the interface plate 12 is opened, so that the coating is filled in the first cavity 101, and then the interface plate 12 is closed. The entire device is horizontally attached to the external wall opening through the barrel holder 7, and then the grip plate 3 is rotated and gently pulled to lift the bottom rubber plug away from the wall surface to expose the discharge port 13, so that the waterproof coating (waterproof mortar) fully wets the bristles 6, and then the grip plate 3 is rotated and pushed forward to make the rubber plug 5 close the discharge port 13. At the same time, during the rotation process, the bristles are close to the external wall opening and brush the wall surface, thereby achieving the external wall screw hole plugging, which is both uniform and beautiful, and can save materials. The entire implementation process is relatively simple, and the device is easy to carry. It can not only effectively save waterproof coating (waterproof mortar), but also make the external wall screw hole brushed evenly and beautifully, achieving a better sealing effect and reducing the risk of water seepage in the later stage.
