Code for Quality Acceptance of Building Decoration and Renovation Engineering (Lightweight Partition Wall Engineering)

7.1 General Provisions

7.1.1 This chapter is applicable to the quality acceptance of sub projects such as panel partition walls, skeleton partition walls, movable partition walls, and glass partition walls.

Explanation:

7.1.1 The lightweight partition wall referred to in this chapter refers to non load bearing lightweight internal partition walls. There are many types of materials and construction methods used in lightweight partition wall engineering. This chapter summarizes them into four types: panel partition walls, skeleton partition walls, movable partition walls, and glass partition walls. Aerated concrete blocks, hollow blocks, and various small blocks of advanced masonry lightweight partition walls are not included in the scope of this chapter.

During the acceptance of lightweight partition wall engineering, the following documents and records should be checked:

Construction drawings, design specifications, and other design documents for the lightweight partition wall project.

The product qualification certificate, performance testing report, entry acceptance record, and re inspection report of the two materials.

3. Acceptance records of concealed works.

4 Construction records.

7.1.3 Lightweight partition wall engineering should be retested for formaldehyde content in artificial wooden boards.

Explanation:

7.1.3 Lightweight partition wall construction requires on-site retesting of the formaldehyde content of the artificial wood boards used. The purpose is to avoid polluting the indoor air environment.

7.1.4 The lightweight partition wall project should be inspected for the following concealed works:

Installation of equipment pipelines and pressure testing of water pipes in the skeleton partition wall.

2. Fireproof and anti-corrosion treatment for wooden keel.

3. Pre embedded parts or tie bars.

Installation of 4 keels.

5. Setting of filling materials.

Explanation:

The construction quality of concealed works in lightweight partition wall engineering is an important component of the quality of this sub project. This article stipulates the acceptance content of concealed works in lightweight partition wall engineering, among which the acceptance of concealed works for equipment pipeline installation belongs to the project of equipment professional construction coordination. It is required to conduct concealed works acceptance for the installation of equipment pipelines in the skeleton before the cover plate of the skeleton partition wall. Only after the concealed works acceptance is qualified can the panel be sealed.

7.1.5 The inspection batches of each sub project shall be divided according to the following regulations:

Every 50 rooms of the same type of lightweight partition wall project (large rooms and corridors with a wall area of 30m2 of lightweight partition wall) should be divided into one inspection batch, and any room with less than 50 rooms should also be divided into one inspection batch.

7.1.6 Anti cracking measures should be taken at the junction of lightweight partition walls, ceilings, and other walls.

Explanation:

7.1.6 The junction between lightweight partition walls and ceilings or other material walls is prone to cracking, therefore, it is required to take anti crack measures at these parts of lightweight partition walls.

7.1.7 The sound insulation performance of lightweight partition wall engineering in civil buildings shall comply with the provisions of the current national standard "Code for Sound Insulation Design of Civil Buildings" (GBJ118).
