弱电智能工程桥梁在设要注意哪些

  弱电桥梁的设计与施工是弱电工程的一部分。与机房设备相比,它显得无关紧要,但却是弱电工程的基础。一方面,桥梁是道路和桥梁,电缆将机房和终端设备有效地连接在一起,形成一个有机的整体。另一方面,桥保护电缆不被拉、拖、刮、碰,防止主电缆长时间悬吊,长时间保持良好的力学性能。因此,我们不能忽视桥梁的作用,也要正视可能出现的问题。
  The design and construction of weak current bridge is a part of weak current project. Compared with the central computer room equipment, it is irrelevant, but it is the foundation of weak current engineering. On the one hand, bridges are roads and bridges. Cables effectively connect the central machine room and terminal equipment together to form an organic whole. On the other hand, the bridge protects the cable from being pulled, dragged, scratched or touched, preventing the main cable from being suspended for a long time and maintaining good mechanical properties for a long time. Therefore, we should not ignore the role of bridges, but also face up to possible problems.
  1.设计中存在的问题
  1. Problems in design
  1.弱线槽设计消耗:
  1. Design consumption of weak trunking:
山东电缆桥架
  在综合布线系统中,更值得注意的是水平分系统电缆桥架规格的计算,这也是该地区电缆桥架消耗的环节。在综合布线系统中,办公室网络和电话系统布线所占比例,需要覆盖每个办公室的每一个角落。这些电缆通常使用六种较粗的电线,以及到桌面的光纤。从终端到机房,电缆的收敛性越来越大,所以在路径上可以采用各种桥梁规格,节约成本。
  In the generic cabling system, the most noteworthy is the calculation of the cable bridge specifications of the horizontal sub-system, which is also the largest part of the cable bridge consumption in this area. In the generic cabling system, office network and telephone system cabling accounts for the largest proportion, which needs to cover every corner of every office. These cables typically use six thicker wires, as well as fiber optic to the desktop. From the terminal to the machine room, the convergence of the cable is more and more big, so various bridge specifications can be used in the path, saving cost.
  其他弱电线路,如:火灾报警系统(包括广播系统)是飞机上配备更多的,但飞机管道已被埋入;楼宇自控系统的所有设备和管道集中在新风室、空调室、冷冻室、水箱、控制室等房间,飞机上基本没有设备。可以适当地使用螺纹管来促进连接。有线电视系统通常在标准层(办公层),端口只设置在总经理室和会议室。视频监控系统一般安装在走廊或电梯厅的两端。一般公共走廊内只设置电子巡更系统和手机覆盖系统的多点。防盗报警系统和门禁系统随机设置。除公司严格管理外,总公司只在入口处设置总开关,重要部位设置防盗探测器。
  Other weak current lines, such as fire alarm system (including broadcast system), are the most equipped on the aircraft, but the aircraft pipeline has been buried; all equipment and pipelines of building automatic control system are concentrated in the fresh air room, air conditioning room, freezing room, water tank, central control room and other rooms, and there is basically no equipment on the aircraft. Threaded pipe can be used properly to facilitate connection. The cable TV system is usually on the standard floor (office floor), and the port is only set in the general manager's room and meeting room. The video monitoring system is generally installed at both ends of the corridor or elevator hall. In general, the public corridor is only equipped with multiple points of electronic patrol system and mobile phone coverage system. Anti theft alarm system and access control system are set randomly. In addition to the strict management of the company, the head office only sets the main switch at the entrance, and sets the anti-theft detector at the important parts.
  2.弱线槽安装位置:
  2. Installation position of weak trunking:
  顶棚空间非常有限,各种管道都是水平和水平的,各种设备上下交错,特别是在走廊区域,所有项目都很拥挤。没有薄弱的桥梁的地方。一般先安装在风管、消防管和喷淋管中。因此,桥梁设计应综合考虑,并与其他进行适当的协商。施工前,更好多单位编制综合管理图,协商各自桥梁的位置。为了避免挡住强的路,我们不得不取消重做的路。
  Ceiling space is very limited, all kinds of pipes are horizontal and horizontal, all kinds of equipment are staggered up and down, especially in corridor area, all projects are crowded. Where there are no weak bridges. Generally, it is installed in air pipe, fire pipe and spray pipe first. Therefore, bridge design should be considered comprehensively and properly negotiated with other disciplines. Before construction, it is better for multiple units to prepare comprehensive management drawings and negotiate the positions of their professional bridges. In order to avoid blocking the road of strong profession, we have to cancel the road of remaking.
  此外,从配线架到工作区域内各信息口的双绞线长度不应大于90m,电缆桥架路线不应过度缠绕。特别是在建筑物结构复杂的情况下,适当增加通信电缆桥架或设置多个接入点,也能有效避免网络电缆敷设距离过长。
  In addition, the length of the twisted pair from the distribution frame to each information port in the working area shall not be greater than 90m, and the cable bridge route shall not be excessively twisted. Especially in the case of complex building structure, it can also effectively avoid the long laying distance of network cable by properly increasing communication cable bridge or setting multiple access points.
  2建设问题
  2. Construction issues
  1. 弱电立井预埋箱与立桥连接
  1. Connection between embedded box of weak current shaft and vertical Bridge
  这是建筑中更常见的问题之一。一般设计院弱电井图的设计深度受限于预埋箱、设备箱、竖井槽的位置和规格,布局可以考虑。
  This is one of the most common problems in architecture. The design depth of general design institute's weak current well drawing is limited by the location and specification of embedded box, equipment box and shaft slot, so the layout can be considered.
  在项目初期,无法从各个方面去评估业主的需求,弱电项目滞后。在后期,业主(尤其是办公楼)对弱电的需求和功能发生了很大的变化,前期的设计无法估计后期的需求和变化。因此,只做传统的设计是不可原谅的。
  In the early stage of the project, it is impossible to evaluate the needs of the owner from all aspects, and the weak current project lags behind. In the later stage, the owner (especially the office building) has a great change in the demand and function of weak current. The design in the early stage can not estimate the demand and change in the later stage. Therefore, it is inexcusable to only do traditional design.
  2.在施工后期,处理这种联系的方式只有两种:
  2. In the later stage of construction, there are only two ways to deal with this connection:
  它可以连接到小槽或钻到垂直槽的侧壁,然后通过软管连接。这是一件简单的事情,不应该成为问题。但由于施工安排,槽口的安装由土建总承包商负责,甲方安排弱电总承包商通过导线进行设备安装。在穿线之前完成连接路径是合理的,特别是在系统主电缆之前。但在实际工程中,由于施工环节不畅通,存在着种种问题。土建工程总承包按设计图纸施工,未及时做好侧向接地准备;弱电施工单位按照波谷不属于弱电合同范围,为了追赶进度,不考虑后果,匆匆越过了界线。结果,电缆刚好建在桥外,无法关闭,造成被动局面。
  It can be connected to a small groove or drilled to the side wall of a vertical groove and then connected by a hose. This is a simple thing and should not be a problem. However, due to the construction arrangement, the general contractor of civil engineering shall be responsible for the installation of the notch, and Party A shall arrange the general contractor of weak current to install the equipment through the conductor. It is reasonable to complete the connection path before threading, especially before the main cable of the system. But in the actual project, because the construction link is not smooth, there are various problems. The general contracting of civil engineering works was carried out according to the design drawings, and the lateral grounding preparation was not made in time; the weak current construction unit was not within the scope of the weak current contract according to the trough, so in order to catch up with the progress, without considering the consequences, it crossed the boundary in a hurry. As a result, the cable was just outside the bridge and could not be closed, creating a passive situation.
  因为有很多弱电系统,有的弱电井有断点,有的系统,如计算机网络,从用户终端通过弱电井到机房有一条长约90米的线路,没有断点。成千上万的线路已经就位、撤线等,建成后的连接线,人力和财力都无法再投入,而线路确实存在“风险”,很容易损坏线缆,留下隐患。
  Because there are many weak current professional systems, some weak current wells have breakpoints, and some systems, such as computer networks, have a line about 90 meters long from the user terminal through the weak current wells to the computer room, without breakpoints. Thousands of lines have been put in place, removed, etc. after the completion of the connecting line, human and financial resources can no longer be invested, but the line does have a "risk", it is easy to damage the cable, leaving a hidden danger.
  解决这个问题的方法是在线槽边缘做一个大的“缝隙”,用密封把电缆插入缝隙中进行保护,然后固定好盖子。弱电虽然没有明确的规定,但也没有必要通过主管部门(消防报警系统和保安除外)对弱电施工的严格检查,在规定期限内提出整改意见。其他的监督检查要宽松得多,但也违反了“行业建设原则”,这是真的不允许的。
  The only way to solve this problem is to make a big "gap" at the edge of the trunking, insert the cable into the gap with a seal for protection, and then fix the cover. Although there is no clear regulation for weak current specialty, it is not necessary to pass the strict inspection on weak current construction by the competent department (except for fire alarm system and security), and put forward rectification opinions within the specified period. The supervision and inspection of other specialties is much looser, but it also violates the "industry construction principle", which is really not allowed.
