In modern interior decoration, gypsum board partition walls are widely used due to their advantages of lightweight, high strength, fire resistance, sound insulation, and easy construction. This article will delve into the material selection, construction process, and construction requirements of gypsum board partition walls, helping readers to fully understand this practical and beautiful decoration method.
1、 Gypsum board partition material
The main material for gypsum board partition walls is gypsum board, which is divided into two types: silicon calcium gypsum board and ordinary paper faced gypsum board.
Silicon calcium gypsum board
Usage: Silicon calcium gypsum board is mainly used for ceiling decoration, and its unique material and performance make it more suitable for ceiling installation.
Specifications: Common specifications include 60060014mm, 300300mm, and 6001200mm, which can meet the needs of different ceiling designs.
Ordinary paper faced gypsum board
Usage: Ordinary paper faced gypsum board is more flexible and can be used for both ceiling and partition walls.
Specifications and Characteristics: National standard specifications include thicknesses of 9.5mm, 12mm, and 15mm, with a length and width of generally 24001200mm and 30001200mm. After scraping putty, its surface is smooth, and when indoor lighting is not strong, the reflection phenomenon is not obvious. In addition, the paper color of ordinary paper faced gypsum board varies, with gray being ordinary board, light green being moisture resistant board, and pink being fire-resistant board. These characteristics make it suitable for different decoration environments and requirements.
2、 Construction technology of gypsum board partition wall
The construction process of gypsum board partition walls is relatively complex, but each step is crucial to ensure the final decoration effect and quality.
Preparation before construction
Design planning: Based on the requirements of office decoration design, clearly mark the positions of walls and door openings.
Material inspection: Ensure that the variety and specifications of the gypsum board used meet the construction quality requirements.
Pipeline inspection: Check the position of all pipelines related to the wall to ensure that the route is correct before construction can proceed.
Dragon bone installation
Along the ground and along the top keel: Before installation, place 5mm thick rubber pads around the perimeter, with the same width as the keel. It is best to use nail fixation along the ground and top keel, with a spacing of less than 600 millimeters.
Vertical keel: The spacing is generally 400 millimeters, arranged from one end of the wall. When the last keel is larger than the design spacing, an additional one should be added. Add a keel on each side of the doorway to strengthen the structure.
Main keel: Insert the upper and lower ends into the edge keel with a spacing of no more than half the width of the gypsum board plus a gap (usually 5 millimeters). The vertical main keel against the wall or column is fixed with nails, with a nail spacing of no more than 900 millimeters.
Sealing plate and pipeline installation
Sealing board: Based on the centerline of the partition wall marked on the ground, use a plumb bob to lead it to the ceiling, ensuring that the centerline of the groove on the partition wall matches the centerline of the ground. After verifying the accuracy of the ground line and the ink lines of the reserved openings for doors and windows, the board can be sealed. When sealing the second side panel, construction can only be carried out after the installation pipeline is in place.
Pipeline installation: When installing distribution boxes, sockets, wall pipes and other devices in partition walls, effective sealing treatment should be carried out on the surrounding gaps.
3、 Construction requirements for gypsum board partitions
To ensure the quality of gypsum board partition walls, the following requirements should be strictly followed during the construction process:
Gap treatment
Horizontal joint: If it is not on the edge keel, a horizontal keel should be added to fix the gypsum board.
Door treatment: The upper faces on both sides of the door should not be sewn together, and L-shaped plates should be used for staggered installation.
Misalignment arrangement: The inner and outer layers of gypsum boards on one side of the keel should be staggered, and the joints should not be arranged on the same keel.
Fixing and sealing
Screw fixation: When fixing gypsum board with self tapping screws, the distance from the edge should not be less than 15 millimeters. The spacing between screws along the perimeter of the gypsum board should not exceed 200 millimeters, and the spacing between screws in the middle should not exceed 300 millimeters. The nails should be slightly embedded in the board, but should not damage the surface of the board, and should be coated with anti rust paint and smoothed with putty.
Hidden seam treatment: Leave a 5mm gap at the seam and embed it. Apply fiberglass tape or perforated paper tape externally, and level with matching joint putty.
Sound insulation and sealing
Sound insulation requirements: There should be a 5mm gap between partition boards with sound insulation requirements, which should be filled with putty and then processed in the order of concealed joint treatment. There should also be a 5mm gap around and sealed with sealant.
Paste and fix: The pasted gypsum board must not peel off, and the nails should be slightly recessed into the surface of the board. The connection between the partition keel and the base structure should be firm and free of looseness.
surface quality
Appearance requirements: The surface of gypsum board should be free of defects such as pollution, cracking, missing edges, falling corners, and bumps. The surface of gypsum board pasted and fixed with nails and screws should be flat.
