Atlas of Rigid Connections for Prefabricated Houses

The following content can be referred to in the Atlas of Rigid Connections for Prefabricated Houses:

1. Standard Atlas of Steel Structures for Lightweight Portal Frame Houses This atlas includes detailed drawings of rigid connections between beams and central columns at the ridge, with the specific number 02TD-101. It is applicable to lightweight steel-structured portal frame houses and focuses on demonstrating the rigid connection structures at beam-column joints, including detailed designs for welding and bolt connections. It can be directly used to guide the rigid connection construction of prefabricated steel-structured houses.

2. Analysis of Rigid Practices in Architectural Construction Atlases Although the Architectural Construction Atlas does not directly provide the number of an atlas for rigid connections in prefabricated houses, it analyzes various rigid construction practices:

• Equal-height roof separation joints: Sealed with rigid waterproof materials (such as concrete) to ensure the integrity of the roof.
• Unequal-height roof separation joints: Treated with rigid structures to prevent cracking caused by temperature differences or settlement.
• Roof parapets: Enhanced wind resistance through rigid connections, such as embedding steel bars and anchoring them to the roof structure.
• Roof eaves gutters: Designed with rigid joints to prevent leakage, such as reserving expansion joints during concrete pouring. Although these practices are not directly aimed at prefabricated houses, they can provide construction ideas for rigid connection design.

3. Rigid Connection Technologies for Prefabricated Building Components and Fittings Relevant literature describes the rigid connection methods between components such as exterior wall panels and interior partition walls and the main structure:

• Exterior wall panels: A gap of 30-50mm is reserved between the panel and the main structure, sealed with fireproof materials, and rigidly fixed with metal connectors.
• ALC panel partition walls: A top gap of 10-20mm is left between the panel and the main structure, and rigid connections are achieved through dry installation (such as fixing with U-shaped steel clips) or wet installation (such as filling with cement mortar).
• Exterior doors and windows: Connected to the main structure through embedded parts by welding or bolting to ensure wind pressure resistance.

4. Rigid Connections between Prefabricated Floor Slabs and Supporting Structures The rigid connection methods between prefabricated floor slabs and supporting structures include:

• Double-T slab rib bottom connections: The slab ribs are fixed to the supporting beams or columns by welding or bolting.
• Tongue-and-groove connections: The overall rigidity is enhanced by interlocking the convex and concave edges of the floor slabs.

Summary: If a specific atlas number is required, 02TD-101 is the directly relevant standard atlas; other rigid connection practices can be designed by combining the construction analysis in the Architectural Construction Atlas with literature on prefabricated component connection technologies. In practical applications, appropriate rigid connection methods should be selected based on the house type, load requirements, and construction conditions, ensuring compliance with current specifications.
