554. Detailed Timber Deck Construction CAD Drawing with Free Download

This document provides a detailed description of the provided CAD technical drawing. The drawing presents the design and construction specifications for an outdoor timber deck area complete with an integrated staircase. It is comprised of four main sections: an overall plan view, two detailed structural cross-sections, and an isometric view of a drainage component.

Here is a detailed description of each part:

1. Stair/Deck Plan at Elevation

This is a top-down view of the entire area, showing the layout and overall dimensions:

Dimensions: The overall width of the deck area is approximately 4300mm and the length is 2300mm.
Timber Decking: The main floor area is surfaced with parallel timber planks.
Staircase: A 900mm wide staircase provides access to the timber deck.
Landscaping: A small area is designated for planting or decorative landscaping.
Lighting: White dots are marked on the stairs and deck, likely indicating the positions of decorative lights.
Drainage: A drainage channel is positioned along the edge of the timber deck.

2. Timber Deck Section 1-1

This cross-section details the construction of the wall adjacent to the deck, which could be a planter box or a retaining wall:

Finishing Layer: The outermost layer consists of a high-quality external render with exterior-grade paint.
Reinforced Concrete (RC) Wall: A 100mm thick RC wall.
Waterproofing: A waterproofing membrane to prevent water ingress.
Plaster Layer: A 12mm thick layer of cement and sand plaster.
Brick Wall: A 230mm thick brick wall.
Lean Concrete: A 150mm thick layer of lean concrete at the base.

3. Timber Deck Section 2-2

This cross-section shows the detailed structural composition of the timber deck system itself, from top to bottom:

Timber Decking: The top finishing layer of deck planks.
Joists: 150x50mm timber joists that directly support the decking.
Bearers: 75x75mm C-channel steel bearers that form the main support structure for the joists.
RC Stumps: Reinforced concrete stumps that elevate and support the bearer system.
Blinding Layer: A 100mm thick layer of lean concrete.
Hardcore Layer: A 250mm thick layer of compacted hardcore to create a stable base.
Existing Ground Level: The level of the original ground.

4. Isometric View of Drainage Gutter

This is a 3D view of a precast concrete drainage gutter, showing its shape and dimensions (400x400x250mm). This component is used to collect and channel rainwater away from the deck area.

Summary

Overall, this is a comprehensive set of technical drawings that provides complete information on the materials, dimensions, and construction methods for an outdoor timber deck project. The drawing clearly illustrates all structural layers, from the foundation to the surface finish, ensuring a structurally sound, durable, and well-drained installation.
