Container House Screw Assembly Diagram

Currently, there is no direct container house screw assembly diagram available, but key steps and points for screw assembly can be outlined by combining relevant installation instructions and material information.

I. Basic Materials and Accessories for Screw Assembly

The screw assembly of container houses primarily relies on galvanized thickened frames and related accessories. These materials include columns, beams, corner fittings (corner pieces), etc., which are connected and fixed with screws. For example, a 3X6-meter quick-assembly container house typically requires 4 columns, four beams for the upper and lower frames respectively, 8 corner fittings, and a total of 64 screws to connect these components. These screws and accessories collectively form the stable structure of the container house.

II. Key Steps for Screw Assembly

1. Bottom Frame Installation: On a flat ground, connect the bottom corners of the container with the bottom beams using hexagon socket bolts, but do not tighten them yet. After adjusting the diagonal differences of the bottom frame (ensuring ≤3mm), tighten the bolts.
2. Secondary Beam Installation: Install π-shaped secondary beams according to the positioning hole positions on the long beams and fix them with self-tapping screws. At the same time, the tops of the π-shaped secondary beams and the bottom beams need to be fixed with round-head drill-tail screws to ensure structural stability.
3. Wall and Door/Window Installation: After lifting and smoothly unfolding the main frame, push open one wall and tighten it with fastening screws. Then, push open the other wall with doors and windows and fix it with fastening screws as well.

III. Selection and Usage Precautions for Screws

When selecting screws, attention should be paid to their material, specifications, and corrosion resistance. For example, 304 stainless steel hexagon socket screws are widely used in the assembly of container houses due to their excellent rust and corrosion resistance. In addition, the specifications of the screws should match the thickness and hole diameter of the connected components to ensure stable and safe connections. When using screws, follow the installation instructions for correct operation to avoid structural instability or damage caused by over-tightening or under-tightening.
