This image presents a side-by-side comparison of a technical drawing and a photograph, illustrating a specific architectural detail. The left side is a cross-sectional drawing, and the right side is a photograph of the finished product.
Technical Drawing (Left Side)
This drawing provides a detailed cross-section of a sloping roof or terrace with a glass railing system. All dimensions are in millimeters.
* Railing System:
* top rail: The handrail at the top of the glass.
* fitting for triplex: The bracket or fitting that attaches the handrail to the glass.
* metal post: The vertical structural posts that support the glass. The post is anchored into the concrete slab below.
* triplex: This is the glass panel itself. "Triplex" is a common term for laminated safety glass. The drawing shows the glass is secured to the metal post. The dimension `100` likely refers to the height of the glass panel.
* Roof/Terrace Structure:
* concrete: The main structural slab of the roof/terrace.
* metal plate: A plate, likely made of metal, that's embedded in the concrete.
* cement-sand mortal: A layer of mortar or screed on top of the concrete slab.
* tile: The finished floor covering on the terrace.
* Edge and Drainage:
* insulation: A layer of insulation is shown below the concrete slab. This is crucial for thermal performance.
* soil: The ground surrounding the structure.
* A slanted edge is detailed, which is designed to direct water runoff.
Photograph (Right Side)
The photograph shows a finished architectural project that matches the details in the drawing.
* Glass Railing: A transparent glass railing is visible, supported by light-colored posts. The glass panels appear to be laminated, consistent with "triplex" from the drawing.
* Green Roof/Sloped Terrace: The structure is covered with grass, creating a green roof or a sloped terrace. This corresponds to the `soil`, `insulation`, and structural layers shown in the drawing.
* Visual Match: The dashed square highlights a section of the railing in the photograph that corresponds to the cross-section detail on the left, demonstrating how the drawing translates to the final built form. The way the posts anchor to the structure and the angle of the railing are consistent in both images.
* Context: The background shows other buildings and a clear blue sky, suggesting an urban or suburban setting. The logo at the bottom right, "ARCHLESIA," likely belongs to the architecture or engineering firm responsible for the design.
Overall Interpretation
The image is a powerful and clear presentation of a design-to-reality process. It uses a detailed technical drawing to explain the construction and material layers of a specific architectural element—a glass railing on a sloped green roof—and then shows a photograph of the completed project, which visually confirms the drawing's intent. This combination of drawing and photo is a common and effective way for architects and engineers to communicate design intent and finished product.
