Baotou GRC What are the design of European component construction organization?
1. Preparation before construction
(1) Technical preparation
Prepare Baotou GRC The construction scheme of the project, and the written technical and safety disclosure to the workers.
(2) Material requirements
1) Hangers, connectors and connectors.
2) Spare parts: suspender, expansion bolt, rivet.
3) The type, specification and quality of materials selected according to the design requirements shall meet the design requirements.
(3) Main machines and tools 1) Electric machines and tools: electric saw, toothless saw, nail gun, electric hand drill, impact hammer, electric welding machine.
2) Manual machines and tools: riveting gun, hand saw, pliers, screwdriver, wrench, steel ruler, steel level ruler, plumb bob, etc.
(4) Operation condition 1) The suspended ceiling works shall be familiar with the construction drawings and design instructions before construction.
2) The suspended ceiling works shall be familiar with the site before construction. A. Before construction, the clear height of the room, the elevation of the opening and the elevation of the pipes, equipment and their supports in the ceiling shall be handed over for acceptance according to the design requirements. B. Check and accept the installation of pipes and equipment in the ceiling and the pressure test of water pipes. C. Check the material mobilization acceptance records, re inspection reports and technical disclosure records.
2. Key quality points
(1) Key requirements for materials
The GRG surface coating must be consistent in color, flat in surface, and the geometric dimension error is within the allowable range.
(2) The key technical requirement is that the line snapping on site must be accurate, and the next process can only be carried out after re inspection. GRG machining dimension must
Accurate, pull through wire during installation.
(3) Key quality requirements
1) The ceiling connecting layer must be firm and flat: adjust the camber by using suspender or suspender bolt. The GRG panel shall be assembled in strict accordance with the horizontal standard line and the gauge square line for setting out. The stressed nodes shall be bound tightly and firmly to ensure the overall rigidity. The size of the ceiling connecting layer shall meet the design requirements, and the vertical and horizontal cambers shall be uniform and mutually adaptive. The internal structure of the suspended ceiling is strictly prohibited from hard bending. If there is, it must be straightened and then fixed.
2) The ceiling surface course must be flat: snap lines before construction, and arch in the middle according to the horizontal line. The lifting pieces must be firmly installed and must not be loose or deformed. The geometric dimensions of the GRG grid must meet the design requirements and the modulus of the facing plate. The varieties and specifications of the veneer shall meet the design requirements, and the appearance quality must meet the specifications of the material technical standards. When tightening the screws of the decorative plate, avoid that the two ends of the plate are tight and the middle is loose, and the surface is concave. The plate can be assembled only after the plate leveling gauge is square. The improper parts should be adjusted and then fixed. The fixing points at corners shall be accurate and installed tightly.
3) The joints should be flat: before decoration, the angle and the regularity of the surrounding should be strictly controlled, and the size should be consistent. During installation, the straight line shall be pulled, and the trim panel shall be arranged according to the center line of the butt joint
Keep it neat. The installation shall be carried out along the center line and side line, and the joints shall be uniform. The layering shall be nailed along the binding line, and shall be smooth and smooth, with neat lines and tight joints.
3. Key requirements for occupational health and safety
(1) When using electric tools, the electricity shall comply with the Technical Code for Safety of Temporary Electrification on Construction Site
(2) When working at height, the scaffold shall be erected in accordance with the Beijing Code of Safe Operation for Construction Engineering
(3) Corresponding protective measures shall be taken to prevent dust pollution during construction.
(4) For special types of work of electric and gas welding, attention shall be paid to the provision of complete health and labor protection equipment for construction personnel.
4. Key environmental requirements
(1) The construction process shall comply with the Code for Indoor Environmental Pollution Control of Civil Building Engineering
(2) Noise pollution shall be prevented during construction. Low noise equipment shall be used in the noise sensitive area of the construction site boundary, and other noise reduction measures can also be taken.
