Acceptance of the intelligent building system project shall adopt the acceptance mode of sub-system, phased, multi-level, and pre-dispersion and centralized inspection. Acceptance of the entire system shall be divided into single device acceptance according to the construction and commissioning operation phases, subsystem function acceptance, system linkage (integration) Acceptance, third-party test and acceptance, and system completion acceptance are five levels of acceptance.
The content of acceptance work at each stage is as follows:
1. Acceptance of single equipment
System single equipment acceptance refers to the pre-installation inspection test and equipment installation in place, power-on test, usually on-site installation of equipment. Acceptance of single equipment is a necessary condition for system commissioning. At the same time, equipment inventory can be checked in time according to quality, performance indicators, proof of origin, actual quantity, etc. Single equipment inspection can be performed by the supervision organization owner, installation unit, system general contractor, equipment Vendors, etc. participate together. The acceptance report shall include the supply contract, random data, certificate of origin of the imported equipment, declaration form (certification of commodity inspection), equipment installation and construction plan and technical drawings, installation equipment name, model specifications, quantity, test data, etc.
2. Subsystem function acceptance
Subsystem functional acceptance refers to the timely implementation of functional acceptance for commissioning of qualified subsystems so that the system can be put into trial operation early. The inspection organization owner, installation unit, system general contractor, and property management department can jointly participate in the inspection. The acceptance report should include the system. Functional description (technical solution), project contract, system commissioning (acceptance) outline, system commissioning (acceptance) records, system operation manual (specification), etc. Subsystem function acceptance is a necessary condition for subsystems to enter trial operation. The system general contractor should also organize timely technical training for property personnel.
3. System linkage (integration) acceptance
The system linkage (integration) acceptance is a functional acceptance of the system, and the difference with the subsystem function acceptance is that: the system linkage (integration) acceptance object is the linkage function between the subsystems under normal operating conditions of the subsystems, or each Subsystem integration function. Acceptance may be jointly attended by the supervision organization owner, system general contractor, and property management department.
Note: If any quality problems are found in the above four-tier acceptance, the non-conformity quality report shall be filled in, and the rectification shall be promptly corrected to correct the non-conformity. After the re-inspection is passed, the participants involved in the inspection and acceptance shall sign and archive the inspection report to prepare the data for reorganization. Delivery.
4. Third-party test and acceptance
Intelligent control system through the system function and linkage (integration) acceptance, and after a certain period of time courtesy, should be organized by the state authorities to accept the final acceptance. However, because there is no unified department to complete the acceptance of the entire system, it must be accepted by the industry supervisory department. For example, the technical supervision department organizes the acceptance of the integrated wiring system, the acceptance of the intelligent lighting system, and the acceptance of the owner's office and special office automation system. .
Before the subsystem function acceptance, system linkage (integration) acceptance, and third-party testing and acceptance, the quality control department of the construction unit shall perform pre-acceptance inspection to check the technical data and project quality so as to find the problems as soon as possible, take corrective measures, and make pre-acceptance records. .
5. The system is completed and delivered to the owner for acceptance
Show the project effectiveness for the owners, and make explanations for each system. If there are some places that do not meet the expectations of the owners, they need to be recorded and adjusted to the time until the owners are satisfied.
Pressure Beams and circular plates on elastic foundations are considered. In some cases, additional elastic supports are present. The stiffness distribution of the foundation is designed so that the pressure on the foundation is uniform. Sometimes the depth of the beam or plate is also varied, with either a piecewise-constant sandwich or solid cross-section, and a global measure of the deflection is minimized. The total stiffness of the foundation and supports is specified, as well as the volume of the structure. In one type of problem, the edges of the structure are displaced downwards; in the other examples, a downward load is applied. Types of loads include a concentrated central load, a uniform load and a parabolic load. The uniform foundation pressure for the resulting design is often substantially lower than the maximum pressure for a corresponding uniform beam or plate on an elastic foundation with uniform stiffness.
