裝配式建筑電氣設計分析

  1充分了解裝配式建筑的構造、加工、施工等基本特性,明確具體項目中各單體采用的裝配式結構體系及預制混凝土構件分布情況,制定科學、合理、經濟、高效的設備管線安裝敷設總體方案。
  2在進行土建預制裝配施工的過程中濃,必須要制定一個科學、合理的施工方案,這樣電氣設計的做法和設計流程才能變得更加合理。在進行建筑電氣設計的過程中,要對其的電氣設計做法和流程進行調整,對建筑結構和各項參數進行定量,并且還要不斷結合建筑預制墻和疊合樓板的特殊構造和具體分布,并制定合理的管線敷設路由排布方案,對其的重點區域進行規劃,不斷結合建筑施工的實際情況進行預制構件的預埋和預留。在進行預制裝配式建筑干預局部板墻構件拆分的時候,要對其的形式方案進行拆分和協商,這樣建筑土建預制裝配施工的質量才能的得到提升。
  3戶內配電箱、弱電箱方位
  (1)在進行預制裝配建筑弱電箱和戶內配電箱安裝的過程中,要對其的方位進行精準的確定,這樣每戶的信號和電源才能滿足用戶的需求。弱電箱和戶內配電箱在施工過程中需要集中大量的管線,一般情況下都不會安裝在預制墻體上的,這樣不僅可以減少弱電箱和戶內配電箱的難度,同時還能有效的減少安裝的難度。在住宅內部安裝的時候,弱電箱和配電箱分布在住宅的兩側,并且在進行安裝的時候,還要對建筑本身的結構進行嚴格的復核,這樣才能保證建筑墻體的防火性和隔音性能夠達到建筑施工相關標準的要求。
  (2)建筑弱電箱和戶內配電箱疊合板塊的管線相對來講出現回路非常集中,并且進出的管線非常大,這種現象導致進出管線之間經常會出現交叉現象,其中配電箱的管線本身的外管直徑整體大于40mm,現澆層厚度一般都在80-60mm,現澆層已不能保證電氣管線的敷設在避讓鋼筋網片的同時確保樓板的結構施工質量。在此情形下,除設法分流該處的管線外,可通過減少建筑面層增加現澆層厚度來解決問題;如還不能滿足,可要求結構專業調整局部方案,在戶內配電箱、弱電箱相對應部位的區域采用傳統全現澆樓板,而戶內其他部位仍采取疊合樓板,以確保樓板的結構應力安全。
  4結語
  綜上所述,在進行預制裝配式建筑電氣設計的時候,設計人員必須要制定高效、科學、合理的排布路由和設備管線敷設方案,這樣裝配式建筑的整體性和節點把握水平才能得到提升,裝配式建筑電氣設計的合理性才能得到提高。
    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 。
    4 Conclusion
    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.
