Description

Technical Field

[0001] The invention relates to the technical field of wall construction, in particular to an anti-cracking wall and a construction method thereof. Background Art

[0002] Wall cracking is a common problem in construction. The reasons are varied, including structural defects, environmental factors, material quality problems and improper construction. The concrete surface is not roughened or the roughening quality is poor, making it difficult for the mortar surface to adhere, resulting in hollowing, dripping and cracking. When applying putty, the wall base is not leveled and cleaned, resulting in gaps and falling off between the putty base and the wall. The traditional hanging mesh does not have a strong adhesion to the wall. Even if the putty material is applied in time, it is difficult to ensure a relatively strong adhesion with the wall base. After applying the putty, attention should be paid to temperature and humidity. Too fast water loss can also easily cause cracking. Therefore, we propose anti-cracking walls and their construction methods. Summary of the invention

[0003] In view of the above technical problems in the related art, the present invention provides an anti-cracking wall surface and a construction method thereof, which can solve the above problems.

[0004] To achieve the above technical objectives, the technical solution of the present invention is implemented as follows: A crack-proof wall comprises a wall base, a fixing strip fixed on the surface of the wall base, and a tie plate vertically inlaid with the fixing strip, wherein both sides of the tie plate are vertically and equidistantly fixed with fixing base oblique strips, and oblique bracing strips are inserted and arranged outside the fixing strips.

[0005] Furthermore, the length direction of the tie plate is parallel to the vertical direction of the wall base surface, the bottom end of the base oblique strip is in contact with the surface of the wall base surface, and the top end of the base oblique strip is inclined toward the top end of the wall base surface.

[0006] Furthermore, a plurality of slots for engaging with the fixing strips are vertically provided on one end surface of the tie plate close to the wall base surface, and the slots are located below the inclined strips of the fixing base.

[0007] Furthermore, a plurality of insertion holes are equidistantly provided on the outside of the fixing strip, and an insertion column for being embedded and matched with the fixing strip is fixedly provided on the bottom of the diagonal support strip.

[0008] Furthermore, a plurality of penetration holes are provided on the surface of the tie plate.

[0009] A construction method for anti-cracking wall surface specifically comprises the following steps: S1: Level the wall surface and remove dust and oil stains; S2: Fix the fixing strips at equal distances on the surface of the wall base, the tie plates and the fixing strips are perpendicular to each other, and the tie plates and the fixing strips are snap-fitted together; S3: Adjust the putty material required for the wall base surface, use tools to fill the putty material to the surface of the wall base surface, until the putty material fills and covers the entire surface of the wall base surface, and the total thickness of the putty material is 3mm~5mm larger than the narrow side width of the tie plate; In step S3, applying putty is divided into two steps. The first step is to apply the putty to a thickness that is flush with the end surface of the tie plate. Wait for the putty to dry for 2 hours. At this time, the putty is not completely dry, and continue to apply the second layer of putty material until the total thickness of the putty material is 3mm~5mm larger than the narrow side width of the tie plate.

[0010] The beneficial effects of the present invention are as follows: the wall base surface fixing strips of the present application cooperate with the diagonal bracing strips to provide limited support for the tie plate with the base fixing diagonal strips. By setting the tie plate, it is convenient to control the thickness of the first layer of putty material and apply it. The diagonal bracing strips can provide auxiliary support for the base putty layer, thereby improving the firmness of the base putty layer and reducing the cracking caused by the separation of the putty material from the wall surface in the later stage.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0016] Embodiment 1: Figure 1-3As shown, according to the present invention, an anti-cracking wall is disclosed, comprising a wall base 1, a fixing strip 2 fixed to the surface of the wall base 1, and a tie plate 3 vertically inlaid with the fixing strip 2, both sides of the tie plate 3 are vertically equidistantly fixed with fixing base oblique strips 4, the fixing strip 2 is externally plugged with an oblique support strip 6, the narrow side width of the tie plate 3 is 6 mm, the thickness of the fixing strip 2 is 1.5 mm, the length direction of the tie plate 3 is parallel to the vertical direction of the wall base 1, the bottom end of the fixing base oblique strip 4 is in contact with the surface of the wall base 1, the top end of the fixing base oblique strip 4 is inclined toward the top end of the wall base 1, and the tie plate 3 is vertically provided with a plurality of card slots 5 for card connection with the fixing strip 2 near one end face of the wall base 1, the card slots 5 are located below the fixing base oblique strip 4, and a card slot is arranged below each oblique support strip 6 5. The spacing between the vertically adjacent slots is set to 20 cm, and the spacing between the vertically adjacent two fixing strips 2 is set to 80 cm. A plurality of plug-in holes 7 are equidistantly provided on the outside of the fixing strip 2. A plug-in column 601 for inlaying and cooperating with the fixing strip 2 is fixedly provided at the bottom of the diagonal support strip 6. After the relative positions of the fixing strip 2 and the tie plate 3 are determined, the plug-in column 601 of the diagonal support strip 6 is inserted into the corresponding plug-in hole 7, so that the diagonal support strip 6 and the base diagonal strip 4 are supported and installed in a fitting manner. Since the diagonal support strip 6 and the base diagonal strip 4 are both inclined, the fixing strip 2 can play the role of limiting the tie plate 3. A plurality of penetration holes 301 are provided on the surface of the tie plate 3. The penetration holes 301 are used for contact between putty materials, so that a connection relationship can be established between the putty materials and each tie plate 3. The construction method of anti-cracking wall specifically includes the following steps: S1: Leveling the wall base surface 1, using a level tool to check the flatness of the wall base surface 1, repairing uneven areas with cement mortar, and removing surface dust and oil stains; S2: Use expansion bolts to fix the fixing strips 2 equidistantly on the surface of the wall base 1, the tie plate 3 and the fixing strips 2 are perpendicular to each other, the tie plate 3 and the fixing strips 2 are snap-fitted, the slot 5 of the tie plate 3 is snap-fitted with the fixing strips 2, and after the relative positions of the fixing strips 2 and the tie plate 3 are determined, the plug column 601 of the diagonal brace 6 is inserted into the corresponding plug hole 7, so that the diagonal brace 6 and the base diagonal bar 4 are supported and installed in a fit manner; S3: After the putty material required for the wall base surface 1 is adjusted, the putty material is filled to the surface of the wall base surface 1 using a tool, and the putty material is pushed from bottom to top until the putty material fills and covers the entire surface of the wall base surface 1; In step S3, applying putty is divided into two steps. In the first step, the thickness of the putty is applied to be flush with the end surface of the tie plate 3. After the putty is dried for 2 hours, if the putty is not completely dry, the second layer of putty material is applied until the total thickness of the putty material is 3 mm greater than the narrow side width of the tie plate 3. After the putty is completely dry, spray the surface finishing paint, and finally apply a layer of film on the surface of the finishing paint to prevent the paint surface from cracking due to rapid water loss.

[0017] To sum up, the structure of the anti-cracking wall of the present application is different from the traditional mesh hanging process in that a fixed strip 2 is used in cooperation with an inclined support strip 6 to limit the support of the tie plate 3 with a fixed base inclined strip 4. The installation is flexible and the firmness is high. At the same time, when applying the putty material, the thickness of the tie plate 3 is referred to for application, so as to facilitate the thickness control of the first layer of putty material. The base putty layer will be embedded in the surface of the inclined support strip 6. The inclined support strip 6 can provide auxiliary support for the base putty layer to improve the firmness of the base putty layer, thereby reducing the cracking caused by the separation of the putty material from the wall in the later stage. The putty is applied with a two-coating process. After the putty is completely dry, the surface finishing paint is sprayed. Finally, a layer of film is applied on the surface of the finishing paint to prevent the paint surface from drying and cracking due to excessive water loss. The structure is coordinated with the construction process, which greatly avoids the problem of wall cracking as a whole.

[0018] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
