Technical Field

[0001] The utility model relates to the technical field of anti-cracking structures, in particular to a prefabricated partition wall joint anti-cracking structure. Background Art

[0002] In order to reduce the cost, most buildings now use prefabricated partition walls. When prefabricated partition walls are combined, there will be joints. The quality of these joints will directly affect the subsequent plastering and coating construction. The existing joint filling methods mostly use foam rods, then hang glass fiber mesh and plaster. Although this method is low in cost and simple in process, it is prone to cracking, water leakage and other problems.

[0003] For this purpose, we design a prefabricated partition wall joint anti-cracking structure here. Utility Model Content

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1 and Figure 2In this embodiment: a prefabricated partition wall joint crack prevention structure includes a wall 1, a joint between two walls 1, and a caulking material 2 filled in the joint. Before filling the joint, the floating dust, hollows, weathered layers and easily falling debris at the joint should be removed. When caulking, the caulking material 2 should be filled and filled. The caulking material 2 uses a leveling material, such as cement mortar. A layer of base curing agent 3 is applied on the wall around the joint. The base curing agent 3 should be applied after the caulking material 2 is completely dry. After the base curing agent 3 is applied, it should be naturally dried for 24 hours. If the weather is humid, the drying time of the base curing agent 3 should be appropriately extended. A layer of composite glue 4 is applied on the surface of the base curing agent 3. The composite glue 4 should be applied after the base curing agent 3 is completely dry. A crepe 5 is posted on the composite glue 4. The width of the composite glue 4 is wider than the crepe 5. The width is about 20mm. The crepe 5 is a composite of elastic and plastic materials. It can buffer and disperse the deformation of the wall and ceiling joints, thereby preventing the wall joints from cracking. The crepe 5 should be laid within 4 to 72 hours after the composite glue 4 is applied. When pasting the crepe 5, it should be naturally smoothed and pasted along the joints with your hands. Do not pull or press it hard. After pasting, use a scraper to compact the crepe 5. The joints of the crepe 5 are connected to the adjacent crepes 5 by flat connection. A thin layer of special putty 6 is scraped on the surface of the crepe 5 and the surrounding walls. The special putty 6 is made of white latex and clean water in a ratio of 1:3, and then the putty for indoor use in the building and 325# white silicate cement are mixed in a ratio of 3:1 and poured out. The surface of the special putty 6 is covered with alkali-resistant glass fiber mesh 7. The unit area mass of the alkali-resistant glass fiber mesh 7 should be 160g / m 2 The overlapping width of the joint of the alkali-resistant glass fiber mesh 7 and the adjacent alkali-resistant glass fiber mesh 7 is 100 mm. After all the above operations are completed, the decoration of the surface layer can be operated according to the normal paint coating construction procedure.

[0017] The described crepe cloth 5 has two specifications, one with a thickness of 1mm-1.1mm, a width of 98mm-102mm, and a length of 9900mm-10100mm, and the other with a thickness of 1mm-1.1mm, a width of 198mm-202mm, and a length of 39900mm-40100mm. The crepe cloth 5 of one specification is used for the joints of wall materials of the same material and the joints at the inner corners of the wall corners, and the crepe cloth 5 of the second specification is used for the deformation joints of lightweight strip board partition walls, the plane joints of wall materials of different materials, the joints of wall materials on both sides of door and window openings of partition walls, and the joints at the outer corners of the wall corners.
