How to deal with the foundation of steel structure movable house? The following points cannot be ignored. Steel structure movable houses are widely used temporary housing buildings at present. Although the main skeleton of movable houses is steel structure, its foundation is not. Most foundations are concrete structure. Steel structure movable houses have certain requirements for the hardness of the foundation. The hardness of the foundation determines whether to make special treatment. It is very important for the project to lay a good foundation:
1. First of all, the hardness test shall be carried out. The hardness of special terrain and foundation is quite different from the construction of movable houses. Special treatment shall be made to ensure the smooth installation of steel structure movable houses and their quality. Technicians shall measure them in advance
2. After the foundation measurement is completed, the next step is the foundation pouring. At this time, the key point is to measure the level first. After the pouring is completed, the horizontal error should be controlled within 10mm It is necessary to ensure that the foundation level is within the error, so as not to affect the subsequent work process
3. Generally, the concrete grade is C20 and there is no reinforcement in the foundation. Of course, under special terrain or other irresistible conditions, the final scheme shall be determined according to the measurement of technicians
4. The pouring time is the same as the conventional concrete pouring process. The steel structure movable house can not reduce the process procedure. After the foundation pouring is completed or before the installation of the movable house, sufficient time should be reserved to make the concrete meet the hardness requirements
5. The final pouring, while making the foundation, must be completed together with the indoor ground, and the horizontal height is the same as the foundation, so as to ensure the installation period, quality and beauty after installation After the movable house is installed, the floor is paved indoors, which is convenient and tidy
In addition, the horizontal height of the indoor floor should be 50mm higher than the foundation level to ensure that rainwater will not flow into the room and the firmness of the ground ring beam
