Description

Technical Field

[0001] The invention relates to the technical field of building decoration construction, in particular to a method for closing a prefabricated wall panel glue joint with real stone paint, and in particular to a method for closing a prefabricated wall panel glue joint with real stone paint, which is simple to operate and not prone to hollowing and falling of the real stone paint. Background Art

[0002] Real stone paint is a kind of paint with decorative effect similar to marble and granite. It is mainly made of natural stone powder of various colors. It is applied to the imitation stone effect of building exterior walls, so it is also called liquid stone. At present, prefabricated wall panels are mostly used as exterior wall surfaces as decorative panels, and real stone paint is applied on the decorative panels to achieve the imitation stone effect. The real stone paint on the exterior wall of prefabricated wall panels mostly uses a full batch of putty to cover the PC seams, and the real stone paint splits the seams and re-divides them. This operation has the following problems: the real stone paint at the PC seam position bulges over time, and even falls off. Except for some projects, the PC seams are open seams. Generally, the width of the PC glue seam is 2cm. However, due to the errors of components and hoisting, the glue seam may reach 3~5cm in order to correct the deviation. If the putty is directly scraped and the real stone paint is sprayed, the flexible putty and silicone cannot be effectively bonded. The real stone paint on both sides of the glue seam is likely to warp and fall off. The mutual adhesion performance of putty and glue seams is poor, which is easy to cause hollowing and falling off.

[0003] Therefore, it is of great practical significance to develop a method for sealing the glue joints of prefabricated wall panels with real stone paint, which is simple to operate and not prone to hollowing and falling of real stone paint. Summary of the invention

[0004] Due to the above defects in the prior art, the present invention provides a method for closing the real stone paint at the glue seams of prefabricated wall panels which is simple to operate and not prone to hollowing and falling of the real stone paint, thereby overcoming the defect that the real stone paint is prone to hollowing and falling at the glue seams of prefabricated wall panels.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A method for closing the glue joints of prefabricated wall panels with real stone paint, comprising the following steps:

[0007] (1) Install prefabricated wall panels so that the PC seams and the natural stone paint partition seams are the same;

[0008] (2) Check the PC seams of the prefabricated wall panels. If the PC seam error is too large, cut and repair the PC seams to reduce the PC seam error. Gluing cannot achieve a large range of correction.

[0009] (3) Apply glue to the PC seams;

[0010] (4) Hang alkali-resistant glass fiber mesh cloth at the glue seam;

[0011] (5) Paste masking tape on the joints of the real stone paint;

[0012] (6) Apply flexible putty on the outside of the prefabricated wall panels and then spray real stone paint;

[0013] (7) After the real stone paint is applied, tear off the masking tape at the glue joint;

[0014] (8) Cut off the alkali-resistant glass fiber mesh cloth at the glue seam position;

[0015] (9) Apply glue to the glue joint for the second time and press the alkali-resistant glass fiber mesh cloth into the newly applied glue to prevent the real stone paint at the seam edge from curling, hollowing or falling off.

[0016] The second application of glue will cover the flexible putty and the first application of glue with the alkali-resistant glass fiber mesh cloth hung on it, which can effectively solve the problem of hollowing and falling of real stone paint at the glue seam.

[0017] The method for sealing the natural stone paint at the glue joint of a prefabricated wall panel disclosed by the present invention is simple to operate, and glue is applied once before the construction of the exterior wall decoration layer, and an alkali-resistant glass fiber mesh cloth is hung at the glue joint. After the paint surface construction is completed, the alkali-resistant glass fiber mesh cloth is cut off and glue is applied again. The presence of the alkali-resistant glass fiber mesh cloth can ensure that the natural stone paint and putty on both sides of the glue joint are firmly adhered, and can prevent the natural stone paint from hollowing and falling off. The operation of cutting off the alkali-resistant glass fiber mesh cloth can prevent the alkali-resistant glass fiber mesh cloth from shrinking and contracting synchronously with other parts and causing the natural stone paint to fall off, and reduce the influence of uneven settlement on the glue joint, and the application prospect is good.

[0018] As the preferred technical solution:

[0019] As described above, a method for finishing the glue joints of prefabricated wall panels with real stone paint, the excessive error of the PC joint means that the width of the PC joint is ≥2.5cm. Of course, those skilled in the art can set the error of the PC joint according to actual needs. Only a feasible technical solution is given here, and the width of the exposed glue joint can be adjusted appropriately.

[0020] In the method for applying real stone paint to glue joints of prefabricated wall panels as described above, the requirement for applying glue in step (3) is that the glue joints are straight up and down and left and right.

[0021] As described above, in a method for closing the glue joint of a prefabricated wall panel with real stone paint, when hanging the alkali-resistant glass fiber mesh cloth, both sides of the alkali-resistant glass fiber mesh cloth are hung on two prefabricated wall panels on both sides of the glue joint and the alkali-resistant glass fiber mesh cloth completely covers the glue joint.

[0022] In the method for closing the glue joint of a prefabricated wall panel with real stone paint as described above, the cutting of the alkali-resistant glass fiber mesh cloth at the glue joint refers to cutting the alkali-resistant glass fiber mesh cloth at the glue joint along the length direction of the glue joint.

[0023] In the method for closing the glue joints of prefabricated wall panels with real stone paint as described above, the width of the alkali-resistant glass fiber mesh cloth is 300 mm.

[0024] The above technical solution is only a feasible technical solution of the present invention, and the protection scope of the present invention is not limited thereto. Those skilled in the art can reasonably adjust the specific design according to actual needs.

[0025] The above invention has the following advantages or beneficial effects:

[0026] (1) The method for closing the glue joint of the prefabricated wall panel with real stone paint is simple to operate. Before the construction of the exterior wall decoration layer, glue is applied once, and an alkali-resistant glass fiber mesh cloth is hung at the glue joint. After the paint surface construction is completed, the alkali-resistant glass fiber mesh cloth is cut off and glue is applied again. The presence of the alkali-resistant glass fiber mesh cloth can ensure that the real stone paint and putty on both sides of the glue joint are firmly adhered, and can prevent the real stone paint from falling off due to hollowing;

[0027] (2) The method for closing the natural stone paint at the glue joint of the prefabricated wall panel of the present invention can prevent the alkali-resistant glass fiber mesh cloth from shrinking asynchronously with other parts and causing the natural stone paint to fall off, and reduce the influence of uneven settlement on the glue joint;

[0028] (3) The method for closing the glue joint of the prefabricated wall panel with natural stone paint of the present invention makes it easier to repair the PC joint and the natural stone paint joint at the same time;

[0029] (4) The method for finishing the glue joints of prefabricated wall panels with real stone paint of the present invention can achieve one-time perfection, avoid the risk of large-scale hollowing and falling off of the facade, and has good application prospects.
