What are the reinforcement and construction requirements for container houses?

When opening the container walls, especially the larger holes, it will greatly weaken the rigidity and strength of the box structure. Therefore, the location and size of the container should be carefully and appropriately determined through architectural and structural design. At the same time, the opening rate should be controlled to be no more than 60%, and all openings should be reinforced and reinforced according to the structural strength, rigidity requirements and the setting requirements of door and window frames.

In addition to local reinforcement of openings, it is recommended to add hidden struts, diagonal braces and box bottom supports for larger openings. This clause specifies the principle and reinforcement requirements for the opening of the control box, and gives the structural diagram of the opening and reinforcement for design reference.

1. Structural node design of container house

General provisions

According to the provisions of the relevant standards and in combination with the characteristics of the container shell and structure, this section specifies the principles of joint design and construction, the basic classification of joints, connection calculation requirements and welding quality requirements.

Node structure

10.2.1 This paper draws on engineering experience and proposes two reference methods for connecting corner fittings and backing plates of two box-joint structures. The former is divided into two structures: the welded connection between the corner pieces and the backing plate, and the high-strength bolted connection of the conical positioner between the corner pieces, and the welded connection is easy to process and install.

However, the on-site welding workload is slightly larger, and temporary positioning and adjustment measures should be taken during the installation process; high-strength bolted connections need to be processed with double-ended cones, and the bolt boxes should be partially modified and installed. When designing, attention should be paid to the edge distance of the bolt holes to meet the requirements. Force requirements and available tightening space.

When it is necessary to leave space between the vessel shells for piping to be installed, a nodal structure connected by solder pads can be used. At this point, the pads and their connections should bend due to the horizontal force between the boxes. Sufficient strength and stiffness.

The connection between the container body and the frame of the container prefab should be connected at the corner pieces, and only transmit the horizontal force without restricting the respective vertical deformation. This article provides a reference structure for box and box connection nodes.

2. Foundation Foundation

For houses below 6 storeys, it is usually economical and reasonable to use natural foundations, but when the foundations are weak, the necessary treatments should be carried out to meet the bearing capacity requirements.

The simple single-storey container house foundation method presented in this paper can also be used for container mobile home foundations below three storeys if there is reliable experience at the treated reinforcement site.

Due to anti-corrosion requirements, the floor of the container house should be installed above. It is recommended to seal the surroundings of the bottom of the container to avoid the accumulation of debris or animals on the bottom of the container. See clause 5.4.1 for the closed structure of the bottom space of an elevated container.

3. Construction and acceptance

General provisions

The installation of the main body of the container and the production and installation of the steel structure of the container mobile house shall be subject to the acceptance of the main structure sub-project.

Since container mobile homes are mainly general-purpose or standardized modules, before the formal installation, trial installation and confirmation of the prototype room will help ensure the quality of the project.

4. On-site installation and allowable deviation

When stacking and installing container mobile homes, the order of box installation is to start from one end of the single-level plane, merge the sides of the first row of boxes with the side expansion, and then proceed to the side expansion of the second row of boxes. At the same time, the side expansion is combined with the end and end expansion of the first row.

,So on and so forth. After merging the first layer, the second layer is merged onto the first layer in the same way, and finally the third layer is merged.

The regulations are based on the current national standard 'Code for Construction Quality and Acceptance of Steel Structures' GB 50205 and engineering experience, and the installation tolerances are proposed according to the characteristics of container mobile homes.

4. Derusting and painting

In order to ensure the anti-corrosion requirements of container mobile houses, rust removal and painting should be carried out in strict accordance with the provisions of this article if no design documents are specified.

The rust-removed steel surface needs to be primed within 4 hours, which is mainly to prevent the steel surface from rusting again and affecting the coating quality of the base paint film. Generally, there is no rain within 4 hours after painting. The surface of the lower paint film is not yet cured and will cause damage after rain.
