There will be some problems after the house has been lived for a long time, such as yellowing or cracking of wallpaper on the wall, seepage of water on the wall, cracking of the wall, etc. The appearance of these problems is not only unsightly but also gives people an unsafe feeling. Sometimes it will bring unnecessary trouble to life. Then, what is the reason for the cracking of the wall ? How to deal with the cracking of the wall ? The following Xiaobian will give you some explanations. Wall cracking causes 1. The cracking of the wall may be due to temperature cracking. If this is the case, most of the cracks are in the transfer position of different materials. If horizontal cracks occur at the intersection of the ring beam and the brickwork, the structure of the house will be deformed due to changes in the ambient temperature. 2. The reason for the cracking of the wall may be caused by the sinking of the foundation. After the house is built, the foundation will sink a bit more or less. If the settlement of the foundation is not uniform, there will be relative displacement between the site where the settlement is large and the site where the settlement is small. At this time, the shear force and tension will be generated in the wall. When this additional internal force is greater than the wall's own tensile shear strength, cracks will occur. 3. The reason for wall cracking may also be structural problems. Some owners will remove some structural walls in order to make the space appear larger. This will reduce the wall surface area and reduce the wall bearing capacity. The bearing capacity of the wall is insufficient, resulting in cracking of the wall. How to deal with the cracking of the wall 1. How to deal with the cracking of the wall? For temperature cracking, this kind of situation needs to increase the thermal insulation layer or add the material with low thermal conductivity to control the temperature rise of the layer panel. In this way, the temperature of the panel will be reduced, and the temperature difference between it and the wall can be greatly reduced, which can effectively prevent the top wall from cracking. 2. How to deal with the cracking of the wall? For the cracking of the wall caused by the sinking of the foundation, if the sinking of the house is not serious, the crack can be repaired after the crack has stabilized. Usually repair is to use cement mortar, cement grouting or resin mortar caulking cracking. If the house is severely degraded, support measures should be taken to the house to reduce the load on the foundation and repair it after strengthening the foundation. Pile foundation underpinning and grouting can be used to improve soil properties. 3. How to deal with wall cracking? For structural wall cracking, it is necessary to reduce the weight and load of the upper structure, or add reinforced concrete beams to the upper part of the masonry structure to bear the upper load. It is also possible to appropriately increase the size of the carrier without damaging the main structure, so that the load carrying capacity can be improved. The article concludes: Some old houses also often suffer from wall cracking. We know how to deal with the same situation by knowing the reasons for the cracking of the wall and how to deal with the cracking of the wall . In fact, most of these problems are caused by poor handling during construction. Therefore, for the sake of the family's safety, we must be careful in the decoration.
Self drilling Screw made of 410 stainless steel, high hardness (40 Rockwell C), steel process.
Drilling screw is also very strong hardness, compared to the ordinary screw up, not only to maintain the ability is good, the connection object effect is also very strong, for the performance of the screw, are generally does not need auxiliary processing, can be directly on the object directly drill a Kong Sue into objects, not just use rise very convenient, Also can greatly improve the efficiency of work. This kind of drilling screw can be said to be the first choice of workers in various fields.
