先安装上层，后安装下层，上、下层之间距离要留有余量，有利于后期电缆敷设和检修。水平相邻桥架净距不宜小于50mm，层间距离应根据桥架宽度不小于150mm，与弱电电缆桥架距离不小于0.5m。

Install the upper layer first, and then the lower layer. The distance between the upper and lower layers should be reserved, which is conducive to cable laying and maintenance in the later stage. The clear distance between horizontal adjacent bridges should not be less than 50mm, and the inter-layer distance should not be less than 150mm according to the width of the bridge, and the distance from the weak current cable bridge should not be less than 0.5m.

我们依据施工图设计标高及山东桥架规格，进行定位，然后依照测量尺寸制作支架，支架进行工厂化生产。在无吊顶处沿梁底吊装或靠墙支架安装，在有吊顶处在吊顶内吊装或靠墙支架安装。

We will position according to the design elevation of the construction drawing and the specifications of the bridge in Shandong, and then make the support according to the measured dimensions, and the support will be factory produced. It shall be hoisted along the beam bottom or installed against the wall support at the place without ceiling, and hoisted or installed against the wall support at the place with ceiling.

在无吊顶的公共场所结合结构构件并考虑建筑美观及检修方便，采用靠墙、柱支架安装或屋架下弦构件上安装。靠墙安装支架固定采用膨胀螺栓固定，支架间距不超过2米。

In public places without suspended ceilings, combined with structural components and taking into account the beauty of the building and the convenience of maintenance, it is installed against the wall, column support or on the lower chord of the roof truss. The wall mounting bracket shall be fixed with expansion bolts, and the bracket spacing shall not exceed 2 meters.

在直线段和非直线段连接处、过建筑物变形缝处和弯曲半径大于300mm的非直线段中部应增设支吊架，支吊架安装应保证桥架水平度或垂直度符合要求。

The supports and hangers shall be added at the connection of the straight section and the non-straight section, at the deformation joint of the building and at the middle of the non-straight section with a bending radius greater than 300mm. The installation of the supports and hangers shall ensure that the levelness or verticality of the bridge meets the requirements.

a.对于特殊形状桥架，将现场测量的尺寸交于材料供应商，由供应商依据尺寸制作，减少现场加工。桥架材质、型号、厚度以及附件满足设计要求。

A. For bridges with special shapes, the dimensions measured on site shall be submitted to the material supplier, who shall make them according to the dimensions to reduce on-site processing. The material, model, thickness and accessories of the bridge meet the design requirements.

b.桥架安装前，须与各协调，避免与大口径消防管、喷淋管、冷热水管、排水管及空调、排风设备发生矛盾。

B. Before the installation of the bridge, it is necessary to coordinate with all parties to avoid conflicts with large-diameter fire pipes, spray pipes, cold and hot water pipes, drainage pipes, air conditioning and exhaust equipment.

c.将桥架举升到预定位置，与支架采用螺栓固定，在转弯处需仔细校核尺寸，桥架宜与建筑物坡度一致，在圆弧形建筑物墙壁的桥架，其圆弧宜与建筑物一致。

C. Lift the bridge to the predetermined position and fix it with the support with bolts. At the turning, carefully check the size. The bridge should be consistent with the building slope. For the bridge on the arc building wall, its arc should be consistent with the building.

桥架与桥架之间用连接板连接，连接螺栓采用半圆头螺栓，半圆头在桥架内侧。桥架之间缝隙须达到设计要求，确保一个系统的桥架连成一体。更多相关事项就来我们网站 //www.comprepyme.com咨询吧！

The bridge and the bridge are connected by connecting plates. The connecting bolts are half-round head bolts, and the half-round head is inside the bridge. The gap between bridges must meet the design requirements to ensure that the bridges of a system are integrated. Come to our website for more relevant matters //www.comprepyme.com Ask!
