Modular house foundation treatment requirements
Modular house’s foundation is the basis of modular house, it determine the stability of the modular house. So the foundation construction is very important and very strict requirements.
Foundation construction elements
A：The hardness of the foundation：You should measure the foundation’s hardness before do the concrete base. To ensure a successfully installation and post-installation quality, you have to do some special treatment if the topography is special nad the and foundation stiffness is too different. For detail special treatment, please communicate
with technology department.
B：Foundation’s level：Before pouring the foundation, be sure the foundation in the same level. The error of the level should control to be less than 10mm for the foundation. Please make sure the foundation
level in the error range. Otherwise, you should response for the impact for the modular house’s installation or after installation quality.
C：Concrete grade：The foundation of our standard modular house is C20. Normally no need reinforcement for the foundation. For the special modular house, terrain and foundation, it should subject to the
final drawing of technology department.
D：Foundation pouring time：The pouring process of modular house should be same as the conventional concrete. It can not be reduced process procedures. After complete the foundation, you should leave enough
time to make sure the concrete reaches a predetermined hardness before installation.
E：Requirement：To make sure the process time, installation quality, neat and beautiful appearance, you should make the internal foundation in the same level with the main foundation. After installation, it will
be easy for you to lay the internal floor tile. It look neat and will not cause any impact on the quality and appearance. To ensure that rain will not flow into the interior and the strong degree of
ring beam, the internal floor tile require to be 50mm higher than the foundation’s level.
F：T parametersof modular house’s foundation:
Required live load is 500KG/㎡，dead load is 350 KG/㎡，foundation grade：C20
Straight beam of second floor board，live load150 KG/㎡，dead load 230KG/㎡。
Self weight 58-66 KG/㎡，Seismic crack magnitude 7，reference wind pressure 0.5 KN/㎡.
