Weak current construction process
(1) The reserved holes and pre-embedded pipelines of the system are coordinated with the civil works in the underground layer construction of the initial construction of the building, involving the reservation of the trunking holes of the integrated wiring system and the pre-burial of the system management of fire protection and security. Therefore, in the “pit-cutting†stage of the underground part of the building, the architectural design institute should complement the hole design of the basement and main building of the building and the weak electric construction drawing of the line pipe to ensure the smooth completion of the civil works. .
(2) Construction of the wire trough frame, civil engineering, and weak current systems, etc. The installation and construction of the weak electric system wire trough frame shall be carried out simultaneously with the installation of other management roads (duct pipes, water supply and drainage pipes) after the civil engineering project is basically completed. It can also be installed a little later than the pipeline (about 15 working days), but it must be designed to solve the reasonable placement and cooperation of the weak system wiring rack and the pipeline.
(3) Coordination of central control outdoor layout and civil engineering and decoration works The decoration of the central monitoring room should be synchronized with the overall decoration project. Before the basic decoration of the central monitoring room is completed, the center console and the server/monitoring computer should be positioned. Pay special attention to the door locks in the central control room and wiring closet must be installed!
(4) Positioning, installation and wiring of weak current system equipment. The positioning, installation and terminal connection of the field installation equipment of the weak current system should be closely coordinated with the renovation project.
(5) Debugging of the weak current system The debugging of the weak current system is basically carried out after the installation of the equipment. The debugging cycle of the entire weak current system takes about 30 days.
(6) Acceptance of weak current system for weak current system. Our company recommends that system acceptance should be carried out after successful commissioning of each system and demonstration of corresponding functional and performance tests. And after the completion of the entire weak electricity system acceptance document and the normal operation of the system, the organization completed the settlement.
Three links of weak current construction
(1) The audit drawing of the weak electricity construction drawing is an extremely serious and important technical work. Doing a good job in drawing review work will play an important role in reducing errors in the weak electricity construction drawings and ensuring and improving the quality of the works. Before the drawing meeting, our project team will provide detailed construction drawings of weak electricity to the construction unit, supervision unit and electromechanical subcontracting unit. All units should carefully read the construction drawings, be familiar with the contents and requirements of the drawings, sort out the difficult problems, and put the drawings. The problems that exist in the record are recorded and resolved in the design review and drawing review.
The drawings will be reviewed. It is recommended that the general contractor organization and leadership of the weak electricity construction should be organized by the construction unit, the supervision company, the subsystem equipment suppliers and the electromechanical installers, and carried out step by step, and organized according to the nature of the project and the contents of the drawings. Will review the work. The results of the meeting shall be formed into a summary, which shall be signed by the design, construction, weak electricity general contractor and construction, and distributed as a supplementary technical document for the construction drawing.
(2) Timetable for construction period of weak electricity construction The main time period of the timetable includes: system design, equipment production and purchase, pipeline construction, equipment acceptance, equipment installation, system commissioning, training and system acceptance, etc. Coordination and validation should form a summary or interface coordination document.
(3) Weak electricity construction technology, the construction technology of the weak current construction includes the general contractor of the weak electricity project, the contractor of each sub-system, the supply and installation of electromechanical equipment and the supervisory company, and the internal work of the integrated wiring project team to the construction team. It should be carried out hierarchically.
The emphasis here is on the technical disclosure work within the integrated wiring project team. The purpose is twofold:
First, in order to clarify the characteristics of the construction tasks undertaken, the technical quality requirements, the division of the system, the weak electricity construction process, the weak construction points and precautions, etc., to be able to do so, in order to facilitate the planned, organized, fast and provincial completion Task, the project leader can further assist the technician to understand the digestive drawings.
The second is to elaborate on the specific requirements of engineering technology, safety measures, construction procedures, and the preparation of work tools, so that the responsibility is clear and each is responsible.
The main contents of the weak electricity technology include: the new technology, new technology, new equipment, performance and operation methods of the new materials used in the construction, precautions for pre-embedded parts, and technical records will be recorded accordingly. The industry website Daquan, electrical encyclopedia, the world of electricity I know best.
In general, it is still very comprehensive, and friends can read it with confidence and use it. Xiao Bian believes that after reading the full text, everyone has a comprehensive understanding of the skills of weak electricity construction. During the construction process, I also understand how to complete the entire workflow in an orderly manner.
