The structure of perforated sound-absorbing board is perforated panel and perforated back plate. Aluminum honeycomb sandwich structure is directly bonded by high-quality adhesive and aluminum honeycomb core, and a layer of sound-absorbing cloth is pasted between honeycomb core and panel and back plate. In this way, the flow of air can be prevented, the sound wave is hindered, and the sound absorption coefficient is improved. In general, its large surface and high flatness, together with the light weight of calcium silicate board, make its board surface high strength, light weight, more convenient to install; at the same time, sound absorption, waterproof, fireproof effect are excellent; in addition, in terms of size, shape, surface treatment and color, customers can customize according to their own needs, It greatly meets the personalized needs of customers.

Introduction to the construction technology of perforated sound-absorbing board:

【1】 Construction preparation

1. Material requirements:

(1) The specification and material grade of the surface course shall meet the requirements of design drawings and construction requirements, and the site inspection shall be qualified, and the factory certificate and material certificate shall be provided..

(2) The keel and accessories are qualified in site inspection and have factory certificate and material certificate.

2. Main machines and tools

Small electric table saw, electric hand drill, axe, hammer, flat shovel, punch, screw driver, square ruler, cutting angle ruler, small steel ruler, guiding rule plate, line drop, ink fountain, etc.

3. Relevant conditions of construction operation

(1) Wood bricks or iron pieces shall be embedded in the structural surface of the decorative wall panel and the lintel of the hole.

(2) The framework installation of decorative wallboard should be carried out after the door window and window sill plate are installed, and the nailing panel should be carried out after plastering the wall and floor.

(3) Before the construction, install the machines and equipment, connect the power supply, and carry out the test run.

(4) When the quantity of construction sub project is large and complex, the detailed drawing should be drawn before construction, and the sample should be made first, and then the large-scale operation can be carried out after the sample is accepted as qualified.

【2】 Construction technology

Base treatment → locating and snapping line → checking embedded parts and openings → manufacturing and installation of keel → nailing lining plate → installing surface course

(1) Grass roots treatment.

(2) Find the position and snap the line.

Before installation, the elevation, plane position and vertical dimension shall be determined in advance according to the requirements of design atlas.

(3) Check the embedded parts and openings.

After snapping the line, check whether the embedded parts, wood bricks or wedges meet the design requirements, whether the arrangement spacing size and position meet the requirements of nailing keel; measure whether the position and size of doors and windows and openings are square and vertical and conform to the design requirements.

(4) Lining plate installation.

After the keel is installed and inspected to be qualified, the 18 mm thick non combustible Board shall be installed as the lining plate. The lining plate shall be nailed firmly, the fixed spacing of nails shall be controlled at about 200 mm, the back side shall be painted with fire retardant coating, and the expansion gap of about 5 mm shall be reserved between the splicing plates to ensure the expansion amount of temperature change.

(5) Install the panel.

Panel installation: check the keel position, straightness and fixation of nails before panel installation, and install it after it is qualified; conduct trial assembly after the panel is assembled, and the panel size, joint and joint structure are completely suitable before formal installation

【3】 Quality standard

1. Guarantee items:

(1) Keel, base lining board and decorative panel must meet the design requirements

(2) The type and quality of the plate used in the surface course must meet the design requirements and construction specifications.

(3) Nailing must be firm without loosening.

2. General items

(1) Installation: correct position, neat cutting angle, tight circle and joint, straight and smooth, close to the wall, consistent with the wall size. Allowable deviation of installation.

Allowable deviation

3 protection measures for finished products

1. Batching shall be carried out on the operation platform, and the finished product operation shall not be carried out directly on the ground without protective measures.

2. Protect the finished products of fine wood to prevent damage or pollution. Especially at the entrance and exit, protective measures should be taken in time, such as installing protective strips, corner plates and rubber films, and special personnel should be assigned to take care of them.
