Key Points for Construction and Installation of Ladder Steel Cable Bridge Frame

一、固定梯式钢制重庆电缆桥架支架间距普通不大于1.5m-2.0m。在进出接线盒、箱、柜、转弯的，应在500mm以内应加设支架。

Fixed ladder steel Chongqing cable bridge bracket spacing is generally not more than 1.5m-2.0m. Brackets shall be installed within 500 mm for access boxes, boxes, cabinets and turnings.

二、梯式钢制重庆电缆桥架装置前，应与土建及水暖、通风空调谐和，肯定与通风管、水管之间的穿插问题。依照电让水的准绳，梯式钢制电缆桥架在上面、水管在下面，桥架处于高点，装置在具有腐蚀性液体管道上方，在热力管道下方。

2. Before the ladder steel cable bridge erection in Chongqing, it should be in harmony with civil engineering, water heating, ventilation and air conditioning specialty, and affirm the problem of interpenetration between ventilation pipe and water pipe. According to the criterion of electric yield water, ladder steel cable bridge is above, water pipe is below, bridge is at a high point, installation is above corrosive liquid pipeline, below thermal pipeline.

三、针对梯式钢制电缆桥架施工的通病，充沛思索全厂桥架装置请求，质量技术人员及时编制《梯式钢制电缆桥架施工工艺及控制措施》，把影响梯式钢制电缆桥架工艺质量的客观要素提早停止消弭。

3. In view of the common faults in the construction of ladder steel cable bridge frame, the requirements of the whole plant are fully considered, and the quality technicians compile the "Construction Technology and Control Measures of ladder steel cable bridge frame" in time, so as to eliminate the objective factors affecting the technical quality of ladder steel cable bridge frame ahead of time.

四、梯式钢制电缆桥架及线槽敷设走向应短捷，并应尽量沿墙、沿柱或沿梁敷设。装置必需结实牢靠，横平竖直，无扭曲变形，桥架内壁无毛刺，附件齐全。立柱、支架和托臂的用料规格严厉按设计图纸及桥架规格请求配置。

4. Ladder steel cable tray and trough laying should be short-cut, and should be laid along walls, columns or beams as far as possible. The device must be firm, horizontal and vertical, without distortion, without burrs on the inner wall of the bridge and complete accessories. The material specifications of columns, brackets and brackets are strictly arranged according to the requirements of design drawings and bridge specifications.

五、在梯式钢制电缆桥架设计这一块，设计院提供的图纸设计比拟简单，装置尺寸及资料不齐全，施工处应主动布置人员分离现场实践状况停止图纸会审，对图纸停止部分修正，从本钱和工艺两方面优化施工计划。同时，充沛思索到桥架装置能否与机务的管道装置发作碰撞，建筑能否正确预留埋件等，以防止后期呈现返工现象。

Fifth, in the design of ladder steel cable bridge frame, the drawings provided by the design institute are comparatively simple, and the size and data of the device are incomplete. The professional construction department should actively arrange personnel to separate the site practice, stop the drawings review, make some amendments to the drawings, and optimize the construction plan from two aspects of cost and technology. At the same time, we should fully consider whether the bridge erection device can collide with the pipeline device of the locomotive specialty, and whether the buried parts can be reserved correctly in the construction specialty, so as to prevent the phenomenon of rework in the later stage.
