1. Fully understand the construction, processing, construction and other basic characteristics of prefabricated buildings, make clear the distribution of prefabricated structural system and prefabricated concrete components used by each single unit in the specific project, and formulate a scientific, reasonable, economic and efficient overall plan for the installation and laying of equipment and pipelines.
2 in the process of prefabrication and assembly of civil engineering, a scientific and reasonable construction scheme must be made, so that the electrical design method and design process can become more reasonable. In the process of building electrical design, it is necessary to adjust its electrical design practices and processes, quantify the building structure and parameters, and constantly combine the special structure and specific distribution of prefabricated walls and composite floors, and develop a reasonable pipeline laying routing scheme, plan its key areas, and constantly combine the actual construction Embedded and reserved prefabricated components. When the prefabricated building interferes with the splitting of local panel wall components, the formal scheme should be split and negotiated, so that the quality of the prefabricated construction of civil engineering can be improved.
Orientation of indoor distribution box and weak current box
(1) During the installation of prefabricated building weak current box and indoor distribution box, its orientation should be accurately determined, so that the signal and power supply of each household can meet the needs of users. Weak current box and indoor distribution box need to concentrate a large number of pipelines in the construction process. Generally, they will not be installed on the prefabricated wall, which can not only reduce the difficulty of weak current box and indoor distribution box, but also effectively reduce the difficulty of installation. During the internal installation of the house, the weak current box and distribution box are distributed on both sides of the house, and during the installation, the structure of the building itself should be strictly rechecked, so as to ensure that the fire resistance and sound insulation of the building wall can meet the requirements of the relevant standards of the construction.
(2) Relatively speaking, the pipeline of the building weak current box and indoor distribution box overlapped plate has a very concentrated circuit, and the pipeline in and out is very large, which often leads to cross phenomenon between the incoming and outgoing pipelines. The overall diameter of the external pipe of the distribution box itself is greater than 40mm, and the thickness of the cast-in-place layer is generally 80-60mm. The cast-in-place layer can no longer guarantee the laying of the electrical pipeline At the same time, the structural construction quality of the floor is ensured. In this case, the problem can be solved by reducing the thickness of the cast-in-place layer and increasing the thickness of the cast-in-place layer in addition to trying to separate the pipeline at this place; if it can not be met, the structural specialty can be required to adjust the local scheme, and the traditional full cast-in-place floor slab is used in the corresponding area of indoor distribution box and weak current box, while the composite floor slab is still used in other parts of the room to ensure the structural stress safety of the floor slab 。
To sum up, in the electrical design of prefabricated buildings, designers must formulate efficient, scientific and reasonable layout and equipment pipeline laying scheme, so that the integrity and node control level of prefabricated buildings can be improved, and the rationality of electrical design of prefabricated buildings can be improved.
