The installation height of the mounting bracket can be adjusted within the range of 2.2-2.8 meters. When selecting 2.2 meters, it should prevent man-made demolition and damage. When selecting 2.8 meters, pay attention to the ventilation pipe and other items that affect the visual field of the video detector. The horizontal distance between the mounting bracket and the parking space line can be adjusted within 3-4 meters. When there are two parking spaces, the middle position of the carriageway (width) is selected. This mounting bracket shall be the low installation position of the hoisting equipment in the parking lot. When installing the installation support in the place with slope, the slope of the installation support should be consistent with that of the building. Install the installation support in the building with circular arc, and its circular arc should be consistent. The installation support shall be "horizontal and vertical". After the installation of the installation support, the installation support shall be measured with a level ruler to meet the horizontal requirements, and the laser line projector shall be used to confirm whether the installation support is in a straight line. After the equipment is installed, the height of the installation support and the width of the horizontal distance parking space shall be determined again. Selection of supports and hangers? The following supports and hangers are selected for the installation of installation supports: double pull through wire hangers, single pull through wire hangers, angle iron supports. The double pull through wire hanger is composed of through-bar screws, blasting and beams. Each hanger of the double pull through wire hanger is composed of two through-bar screws. The single pull through wire hanger is composed of through-bar screws, blasting and hanging frame. Each hanger of the single pull through wire hanger is composed of one through-bar screw. Angle iron supports are divided into U-shaped supports and L-shaped supports. Its main material is angle iron, which is used to fix the installation support to ensure that the bridge will not shake at will? The single pull through wire hanger is shown in the figure below. Use a tape measure to confirm the ground point. According to the installation requirements of the video detector of the video parking space guidance system, that is, the video detector is 3 meters away from the front of the parking space line. When the parking space is the corresponding parking space, the installation support should be selected in the middle of the vehicle driving road.

1.使用“激光投线仪”确认顶棚通杆螺丝的位置，并使用电钻进行开孔。激光投线仪，确认安装支架支吊架位置。

1. Use the "laser line projector" to confirm the position of the ceiling through-bar screw, and use an electric drill to make holes. Confirm the position of the support and hanger of the installation support with the laser projection instrument above.

2.安装支架支吊架间距为3米，在直线与弯通连接处0.3米的位置使用吊架。安装支架的安装高度为2.5米。

2. The distance between the support and hanger of the installation support is 3 meters, and the hanger is used at the position of 0.3 meters at the connection between the straight line and the elbow. The installation height of the mounting bracket is 2.5m.

3.根据现场地面与顶棚的高度计算通杆螺丝的长度，并使用切割机进行切割处理。注：确认通杆螺丝位置时建议比原来长度稍长几公分确保可以小幅度调整安装支架水平位置。 五、使用拉爆与通杆螺丝相结合将通杆螺丝固定在顶棚确定的位置，并在通杆螺丝的下端安装吊框，吊框选用安装支架厂商提供的原件。

3. Calculate the length of the through rod screw according to the height of the ground and ceiling on site, and use the cutting machine to cut it. Note: when confirming the position of the through rod screw, it is recommended to be a few centimeters longer than the original length to ensure that the horizontal position of the mounting bracket can be adjusted slightly. 5、 Use the combination of blasting and through-bar screws to fix the through-bar screws at the position determined by the ceiling, and install a lifting frame at the lower end of the through-bar screws. The lifting frame adopts the original provided by the installation support manufacturer.

4.安装支架组装与安装安装支架的直线段之间连接使用厂商提供的连接件。安装支架应当在建筑物伸缩出设置安装支架伸缩 缝。具体办法：安装支架连接处一端安装支架连接片上螺丝不上即可安装支架直线段安装时，直接将安装支架穿过吊框，连接缝使用联接片连接。

4. The connection between the installation support assembly and the straight-line section of the installation support uses the connector provided by the manufacturer. The expansion joint of the installation support shall be set at the expansion outlet of the building. Specific method: install the bracket without screws on the connecting piece of the mounting bracket at one end of the mounting bracket connection. When installing the straight section of the bracket, directly pass the mounting bracket through the hanging frame, and connect the connection joint with the connecting piece.

5.并安装跨界软铜线：安装支架位置矫正与检查确保安装支架安装完成之后处于水平位置，如不符合要求应当立即进行调整。确保安装支架前端与后端处于同一直线上，如不符合要求立即进行调整。

5. Install cross-border flexible copper wire: correct and check the position of the installation support to ensure that the installation support is in a horizontal position after installation. If it does not meet the requirements, it should be adjusted immediately. Ensure that the front end and the rear end of the mounting bracket are in the same line, and adjust immediately if they do not meet the requirements.

6.确保安装支架连接处应有软通线连接，如没有应当立即增加。确保安装支架某一直线段起始端与末端应当有角铁加进行固定，安装支架超过一定距离时应当选用角铁支架进行固定。确保安装支架距离地面高度一致，如不符合要求立即进行调整。确保安装支架距离车位线位置符合设计要求，如不符合要求立即进行调整。

6. Ensure that the connection of the mounting bracket should be connected with flexible wires. If not, it should be added immediately. Ensure that the start and end of a straight section of the installation support should be fixed with angle iron. When the installation support exceeds a certain distance, angle iron support should be selected for fixation. Ensure that the height of the mounting bracket from the ground is consistent, and adjust it immediately if it does not meet the requirements. Ensure that the distance between the mounting bracket and the parking space line meets the design requirements, and adjust it immediately if it does not meet the requirements.
