One-Story Prefabricated Slab House Drawings

Currently, complete drawings for one-story prefabricated slab houses are not provided, but design ideas can be obtained through case references and structural adjustment suggestions, as detailed below:

I. Directly Referable Cases Related to Prefabricated Slabs

1. Mr. Liang's Self-Built House Case (2017)

• Structural Features: The ground floor has a building area of 93㎡ and uses prefabricated slabs for construction. Due to geological conditions (rock layer) and cost constraints, the structural columns were not fully arranged according to specifications, with only 7 columns placed at the outer corners and under the living room's main beam.
• Design Lessons: Drawing the plans by himself resulted in a small bedroom area (actual net area of 10.28㎡). It is recommended that the master bedroom should have dimensions of at least 3.6m in width and 4.2m in depth (approximately 15㎡ in area).
• Construction Points: Special attention should be paid to the treatment of joints between prefabricated slabs to avoid leakage or structural weakness caused by poorly sealed joints.

2. Single-Story Villa Drawings (Main Construction Cost of 120,000 Yuan)

• Structural Type: Brick-concrete structure. It is not explicitly stated whether prefabricated slabs are used, but the drawings include structural diagrams (such as graded design of strip foundations and reinforcement of ring beams). Contact the design team to confirm whether structural adjustments for prefabricated slabs are supported.
• Drawing Contents:
  • Architectural Drawings: Reinforcement of door and window openings, roof drainage slope, lightning protection grounding, etc.;
  • Structural Drawings: Strip foundations (600mm for load-bearing walls/400mm for non-load-bearing walls), reinforcement of ring beams (12mm deformed steel bars);
  • Plumbing and Electrical Drawings: Water supply pipes running along the ceiling, separate strong and weak electrical boxes, positioning of septic tanks, etc.
• Adjustment Suggestions: If prefabricated slabs are to be used, communicate with the design team to modify the structural drawings, focusing on adjusting the span of the prefabricated slabs, load calculations, and joint treatment methods.

II. Applicability of Other Design References

• Drawings for Rural One-Story Self-Built Houses: Emphasize practicality and economy but do not mention prefabricated slabs. Structural calculations and joint treatment details need to be supplemented by oneself.
• Drawings for Villas with Elevated Floors: Suitable for humid areas or sites with elevation differences, with functions including garages and storage. However, the structural type is not specified, and suitability for prefabricated slabs needs to be judged based on geological conditions.

III. Suggestions for Obtaining Complete Drawings

1. Contact the Design Team for the Single-Story Villa: Confirm whether structural adjustments for prefabricated slabs are supported and request modified structural drawings.
2. Refer to Construction Nodes in Mr. Liang's Case: Focus on learning key techniques such as joint treatment between prefabricated slabs and the placement of structural columns.
3. Supplement Professional Calculations: According to local load specifications (such as snow load and wind load) and geological conditions, verify the span of prefabricated slabs, reinforcement, and foundation bearing capacity.
