Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a brushing mould for external wall waterproof paint. Background Art

[0002] With the acceleration of China's infrastructure construction, there are more and more high-rise buildings. Construction teams will leave holes when constructing shear walls. Fixing devices are required during construction. The use of through-wall bolts is a routine measure of construction units, which also creates screw holes in the exterior walls. Improper sealing of the screw holes in the exterior walls often causes quality risks.

[0003] In view of the existing brushing method of waterproof coating, on-site PVC pipes are used as molds for brushing, which not only makes it difficult to control the diameter, but also causes irregular brushing and complicated construction. For example, China Invention Patent Publication No. CN 106401186A discloses a three-color polyurethane plugging construction method for external wall tension bolt holes. The steps of implementing the construction method are: extracting the external wall tension bolt holes, plugging the tension bolt holes with waterproof expansion cement mortar, and then watering and curing; concentrically aligning a brushing ring with a diameter of 150mm with the tension bolt holes, and applying the first coat of white polyurethane coating with a thickness of 4mm; then concentrically aligning a brushing ring with a diameter of 130mm with the tension bolt holes, and applying the second coat of red polyurethane coating with a thickness of 4mm; finally, concentrically aligning a brushing ring with a diameter of 110mm with the tension bolt holes, and applying the third coat of black polyurethane coating with a thickness of 4mm. Its installation is troublesome, and it is necessary to first install a roller on the wall for positioning, which is not convenient for hand-held positioning and is not flexible enough. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an exterior wall waterproof coating brushing mold, which is easy to hold and position, and can be flexibly used for holes after a plurality of tension bolts are disassembled.

[0016] As a further improvement of the present invention, the angle between the handle and the grip is 45 degrees.

[0017] As a further improvement of the utility model, the handle is provided with continuous concave and convex shapes.

[0018] As a further improvement of the utility model, a mounting plate is provided on the outer side of the first painting limiting ring, a positioning bolt is threadedly connected to the end of the mounting plate, and a suction cup is connected to the end of the positioning bolt.

[0019] With such a structure, the suction cup can achieve a stable positioning effect and reduce the unstable performance of the operator's hand-holding.

[0020] As a further improvement of the utility model, the connecting part includes a welding screw welded on the first painting limiting ring, the second painting limiting ring and the third painting limiting ring, the screw is passed through a connecting plate and is tightened by a nut, and the middle part of the connecting plate extends into the adjacent first painting limiting ring and the second painting limiting ring, and between the second painting limiting ring and the third painting limiting ring.

[0033] A third painting limiting circle 3 is arranged concentrically with the second painting limiting circle 2 and has a smaller diameter than the second painting limiting circle 2;

[0034] A connecting member 4, which connects the first painting restriction ring 1, the second painting restriction ring 2 and the third painting restriction ring 3;

[0035] A handle 5, one end of which is fixedly connected to the first painting limiting ring 1;

[0036] The handle 6 is fixedly connected to the other end of the handle 5 and is tilted.

[0037] Such a structure is convenient for the operator to hold and apply three layers of waterproof material according to the sizes of the first painting restriction circle 1 , the second painting restriction circle 2 , and the third painting restriction circle 3 in sequence.

[0038] The handle 6 is made of plastic and connected to the handle 5 at a 45° angle, which is convenient for the mold ring to be attached to the wall for construction. The mold material is steel bar, and the outer layer is painted with anti-rust paint.

[0039] In this embodiment, the diameter of the first painting restriction circle 1 is 140 mm; the diameter of the second painting restriction circle 2 is 120 mm; and the diameter of the third painting restriction circle 3 is 100 mm.

[0040] In this embodiment, the first painting limiting ring 1, the second painting limiting ring 2 and the third painting limiting ring 3 are made of No. 6 steel bars.

[0041] In this embodiment, the handle 5 is made of No. 8 steel bar, has a length of 100 mm, and is welded to the first painting limiting ring 1.

[0042] In this embodiment, the angle between the handle 5 and the grip 6 is 45 degrees.

[0043] In this embodiment, the handle 6 is provided with continuous concave and convex shapes.

[0048] The five steps of painting the screw holes on the exterior wall are: cleaning the screw holes → sealing with mortar on the outside → grouting from the inside → sealing with mortar on the inside → partial self-adhesive waterproof membrane on the exterior wall. The specific steps are as follows

[0049] Step 1: Use an impact drill to break the casing in the screw hole and clean it up (the drilling depth of the inner and outer wall drill bits should be ≥ 50mm);

[0050] Step 2: Fill the screw holes (depth of 50-60mm) with expansive cement mortar (expansive agent content accounts for 3% of cement weight) on the outside of the exterior wall;

[0051] Step 3: Use foaming agent to fill the middle of the wall from the inside of the wall, and the filling depth should be kept at 100-120mm;

[0052] Step 4: Use expansive cement mortar (expansive agent content accounts for 3% of cement weight) to tamp and plug the screw holes in the wall within a depth of 50 to 60 mm inside the wall;

[0053] Step 5: After the mortar in the screw hole of the external wall is fully dried, apply polyurethane waterproof coating to the screw mouth. The first coat is applied according to the outermost steel ring of the mold with a diameter of 14cm, and after it is dried, it is applied along the middle ring with a diameter of 12cm, and after it is dried, it is applied along the middle ring with a diameter of 10cm.

[0054] The utility model is convenient to hold and position, and can be flexibly used for holes after a plurality of tension bolts are disassembled.
