Aluminum Curtain Wall Installation Technology and Construction Management

I. Pre-construction Preparation

1.1 Site Survey, Measurement, and Setting Out

Before starting the muro cortina de aluminio construction, a comprehensive site survey is necessary. This mainly focuses on the stability of the building structure, wall flatness, and the locations of existing obstacles (such as doors, windows, and pipelines). The measurement work requires the use of precision instruments such as laser rangefinders and levels to ensure accurate wall dimension data is obtained. Setting out involves marking key control lines on the wall according to the design drawings, such as the installation positions of the keel and the division lines of the curtain wall panels.

1.2 Material Prefabrication and Factory Processing Flow Control

The main materials for aluminum curtain walls include aluminum alloy profiles, glass/aluminum panels, sealants, etc. The factory processing needs to strictly control the cutting accuracy, with the cutting error of aluminum alloy profiles controlled within ±0.5mm. CNC machining centers are used for profile drilling, milling, and other processing to ensure that the processing dimensions match the drawings. After processing, surface treatment (such as anodizing, fluorocarbon spraying) is required, and the surface quality is strictly inspected.

1.3 Construction Drawings, Detail Drawings, and Technical Disclosure

Before construction, it is necessary to organize technical personnel and construction teams to review the design drawings, focusing on verifying the connection nodes between the curtain wall and the main structure, lightning protection and grounding design, drainage structure, and other key nodes. Technical disclosure should explain in detail the construction process flow, quality acceptance standards, safe operation specifications, and other content to ensure that the construction personnel fully understand the design intent and construction requirements.

II. Installation Process Flow

2.1 Installation of Base, Keel, and Frame Structure

The installation of the base is the foundation of muro cortina de aluminio construction, usually using embedded parts or post-installed anchor bolts to connect with the main structure. The deviation of the embedded parts should be less than 20mm, and the post-installed anchor bolts need to undergo a pull-out test to ensure their bearing capacity meets the design requirements. The keel installation requires installing the vertical keel first, then the horizontal keel, using stainless steel bolts for connection to ensure the overall stability of the frame.

2.2 Installation and Fixing Technology of Curtain Wall Panel Units

Before installing the curtain wall panel units, it is necessary to inspect their processing quality to ensure accurate dimensions and no scratches on the surface. During installation, special gondolas or lifting platforms are used for high-altitude operations. First, connect the curtain wall panel units with the keel, then fine-tune them using adjustable brackets to ensure a flat panel surface and uniform joints. The fixing method adopts self-tapping screws, pressure plate fixing, or hook fixing according to the design requirements.

2.3 Joint Treatment, Sealing, Waterproofing, and Windproof Measures

Joint treatment is a key part of muro cortina de aluminio construction, directly affecting the waterproofing and windproof performance of the curtain wall. The joints need to be filled with weather-resistant sealant. Before injecting the sealant, clean the joint surfaces to ensure no oil or dust. The sealant injection should be full and continuous, avoiding air bubbles and gaps. At the same time, waterproof flashing should be installed at the top and bottom of the curtain wall to prevent rainwater infiltration.

Construction personnel undergo pre-job safety training to familiarize themselves with safety operation procedures and emergency response measures. Regular safety drills are conducted to improve the safety awareness and emergency response capabilities of construction personnel.

3.2 Site Construction Management and Construction Records

A strict management system needs to be established on the construction site to clarify the responsibilities of each position and ensure orderly construction. Construction records should include hidden project acceptance records, quality inspection records, safety disclosure records, etc., to provide a basis for project acceptance and later maintenance.

3.3 Quality Inspection Methods, Acceptance Standards, and Post-maintenance Requirements

Quality inspection includes appearance quality inspection, dimension deviation inspection, sealing performance inspection, etc. The acceptance standards should meet the requirements of relevant specifications such as the “Technical Code for Building Curtain Wall Engineering”. Post-maintenance requires regular cleaning of the curtain wall surface, inspection of the aging of sealants, and timely replacement of damaged parts.

IV. Construction Schedule and Cost Control
