Wall construction is a method that is becoming popular in recent times when construction technology applies pre-engineered steel frames to construction. If you do not know the prefabricated house building walls, it is easy to crack at the junction between steel and concrete. So how to make the prefabricated house to build a sustainable wall, let's find out this method and the causes of wall cracking and how to fix the prefabricated house to build the wall in the most optimal way.
Prefabricated houses have the main structure is steel frame, but some items such as wall foundation are still built with concrete bricks. The steel structure of the prefabricated house needs to ensure a strong connection to prevent rust and fire.
By saving construction costs. Low cost in terms of cost, the raw materials needed for the process also save a lot of money.
Time to build a prefabricated house to build a wall quickly
Regarding the flexible steel structure structure, the aesthetic diversity according to the design is not limited
Cause of prefabricated house with cracked wall
For prefabricated wall construction, if not calculated and carefully monitored, it is easy to form unnecessary cracks due to basic errors.
+ Engineers do not correctly calculate the bearing capacity of steel structures installed into prefabricated houses
+ Prefabricated houses are built with insufficient load-bearing strength of masonry
+ Lack of calculation in case of thermal deformation of concrete and steel structure
+ Discrete in asynchronous construction calculations to ensure certainty
+ The construction is sinking and tilting without control
+ Poor construction technique wrong installation process.
In order to avoid prefabricated houses building walls without cracking, the investor must choose an experienced construction contractor to ensure both expertise and technique and have had the construction process of many similar works. During the design and construction process must be strictly supervised on all stages. Minimize wall cracking at the bottom.
+ When there is a crack, it is necessary to find out the cause and fix it thoroughly. Here are the possible causes and solutions.
+ Distinguishing properties of wall cracks due to cracking of steel structure or deformation of concrete. If it is a crack caused by a steel structure, overcome the weakness of the steel structure at the place where the crack occurs.
+ Depending on the type of crack, choose the appropriate remedy
+ Absolutely follow the rules of building prefabricated houses
+ Welding more small steel bars connecting the beams before building the wall
+ At the positions of the H-shaped steel frame columns, the I-shaped bricks are built tightly and tightly to avoid leaving gaps on the wall.
+ Finished construction of the raw wall when finishing, using cable mesh to cover the adjoining positions between the steel frame and the brick wall and plaster the finish.
