Installation of Cement Prefabricated House Storefronts

The installation of cement prefabricated house storefronts must follow standardized procedures, covering foundation construction, component prefabrication, on-site installation, and acceptance inspection, requiring operation by professional teams and strict quality control.

I. Foundation Construction

Foundation construction is a prerequisite for installation, requiring confirmation of the connection points between the door post foundation and the groundwork according to design drawings. Specific steps include:

1. Positioning of Embedded Parts: Before foundation pouring, accurately position and install embedded parts (such as bolts and steel plates) to ensure connection precision with subsequent prefabricated components.
2. Foundation Pouring: Pour the foundation with concrete, ensuring the strength grade meets design requirements (usually not lower than C25), and reserve sufficient curing time to ensure structural stability.
3. Level and Verticality Calibration: After foundation completion, check surface flatness (deviation ≤ 5mm) and verticality of embedded parts to avoid subsequent installation deviations.

II. Component Prefabrication

The quality of prefabricated components directly affects the overall structural safety and must be produced through standardized processes in factories:

1. Mold Making: Use steel to make molds, ensuring dimensional accuracy (deviation ≤ 2mm). Molds must be regularly inspected and repaired to avoid deformation.
2. Concrete Mixing and Pouring: The concrete strength grade is usually C30-C40, requiring strict control of the water-cement ratio and vibration process to avoid defects such as honeycombing and pitting.
3. Curing and Demolding: After component pouring, cover and maintain moisture for at least 7 days. Demolding can only occur after reaching 75% of the design strength to avoid cracking due to insufficient strength.

III. On-site Installation

On-site installation must be carried out step by step, with real-time correction of deviations:

1. Door Post Installation: Lift the prefabricated door posts to the foundation position, secure them with bolts or welding, and then use a laser level to calibrate verticality (deviation ≤ 3mm/2m).
2. Beam Hoisting: Fix the beams using slot designs or welding methods, ensuring tight joints without misalignment. Welding areas must be rust-proofed.
3. Decorative Treatment: According to design requirements, spray stone-like paint or paste cultural stones, with surface flatness controlled at ≤ 5mm to avoid affecting aesthetics and durability.

IV. Acceptance Inspection and After-sales Service

After installation, a comprehensive acceptance inspection must be conducted, and after-sales guarantees confirmed:

1. Acceptance Criteria: Check component dimensional deviations, connection firmness (such as bolt torque, welding strength), and decorative surface quality, ensuring compliance with the "Quality Inspection Standard for Prefabricated Concrete Components" (GB/T 50204).
2. Manufacturer Responsibilities: Users need to confirm in advance whether the manufacturer provides transportation, installation services, and the scope of after-sales support (such as warranty period, maintenance response time). For example, some merchants in Langfang can provide customized installation and wind and earthquake resistance guarantees.

Tip: It is recommended to choose a qualified professional manufacturer and require them to provide a construction plan and technical disclosure to ensure installation quality and safety.
