The material selected for the cast iron platform plate charge is the choice of pig iron according to GB718-82. The technical conditions and inspection of the cast iron platform: According to the type of cast iron platform, there are different technical requirements for gray iron castings, malleable iron castings and ductile iron. In general, gray iron castings are carried out in accordance with GB976-67. Pig iron for ductile iron is selected according to GB1412-78. Standards are divided into groups, classes, and grades by chemical composition of pig iron, but carbon content is not considered. Inspection can be carried out according to GB1348-88. The shape size and quality deviation shall comply with the drawings or comply with the provisions of GB6414-1999. The grade, processing allowance and dimensional deviation of the platform shall comply with the provisions of the drawings or comply with the provisions of GB6414-1999. 1. The deflection of the cast iron platform is placed on the working surface of the tested platform. When the load is not applied, the torsion spring comparator head is in contact with the working surface (for accurate measurement, a piece can be placed between the probe and the working surface) Thin gauge) and note the reading. Then apply the force according to the rated load specified in Table 5 and record the reading; the difference between the two readings is the deflection value of the working surface of the tested plate under the rated load. 3. Plane fluctuation of cast iron platform Place the plane wave instrument on the working surface of the platform and move the plane wave instrument along any straight line direction. The moving distance is half of the diagonal length of the platform and should not be less than 200MM. Take the difference between the most value and the minimum value on the indicator table of the plane wave meter (index value is 0.001MM). That is, the amount of plane fluctuation of the working surface of the platform to be inspected.

2. The ratio of the contact area of ​​the cast iron platform will be coated with the display agent on the inclined surface of the platform, and will be grounded on the platform board not lower than its accuracy level, showing obvious contact points on the tested platform, and then using a 400 small square transparent sheets (such as plexiglass sheets) with 2.5MM×2.5MM are engraved in the range of 50MM×50MM. Place it at any position on the working surface of the platform to be inspected, and then observe the proportion of the area occupied by the contact points in each square (in units of 1/10). The sum of the above ratios is calculated, and dividing by 4 is the ratio of the contact area of ​​the detected portion. To get a typical value. The ratio of the area of ​​the contact point should be measured at another location to find the average of the two results.
Expandable container house have attracted much attention as a new type of housing construction, and container houses are also used as daily living houses in many regions. Moreover, this type of container house has also become a future residential trend, and its use advantages are also very obvious.
Good energy saving and environmental protection effect
The expandable container house granny house/small house is made of Eps Sandwich Panel, pu Sandwich Panel, aluminum alloy, galvanized steel structure and other materials. Such materials are not only convenient for construction, but also sustainable. Materials, recycling is relatively simple. Such materials can effectively reduce the generation of construction waste, and the raw materials can be recycled for many times. It is a high-quality housing material that truly achieves the purpose of environmental protection.
Cost-effective housing
Concrete buildings are not cheap to construct, and the construction time is long, and immediate occupancy is not possible. However, the fraud of the expandable container house is lower, and its own transportation cost is not high, and it can be used repeatedly in different locations. It is easy to install on site, and it is equipped with a kitchen, toilet, bedroom, living room, oven, microwave oven, and air conditioner. And other configurations, so in terms of building cost performance and comfort, container houses are indeed a good choice.
Strong scalability
The expandable container house can be expanded. Simply put, its space can be expanded according to your needs. If you need to increase the usable area, you only need 3-5 people to fold the wall panels for half an hour to double the area, and it is very convenient to operate. If you don't need the existing space and want to reduce a certain area, you can fold a part appropriately to meet the requirement of area reduction. At the same time, it can also be pulled away with a trailer, and camps can be set up anytime and anywhere. It is a proper mobile house, caravan park, and no construction qualification certificate is required.
Quality Assurance
As long as high-quality materials can be selected, the long-term use of expandable container houses is also guaranteed. But also pay attention to the daily inspection of container houses. If there are bathrooms, kitchens, etc. inside, you should also pay attention to waterproof and circuit problems, so that the use of container houses is safe and can meet the basic requirements of daily life. The service life of our extended container houses can reach 30 years, and they have been exported to the United States, Ordalia and many countries in the European Union.
