Many online equipment support comprises A-frame and a pair of cross arm, A-frame is by C shaped steel 3, tripod bracing 7, 8 welding of tripod support form, the equidistant trompil of the vertical direction of interior side plate at C shaped steel 3 welds M12 hexagon nut 2 in the inboard hole position of C shaped steel 3, C shaped steel 3 is detained at H shaped steel structure post flange board border, four M12 hexagon head bolts 1 are through the hole of hexagon nut 2 and the inboard contact in H shaped steel structure post flange board border for many online equipment support is fixed in on the H shaped steel structure post. The tripod support 8 is provided with two holes for fixing the equipment support cross arm 9, the distance W between the two holes is consistent with the distance between the two longitudinal lifting lugs 11 of the multi-split equipment, and the tripod support 8 and the equipment support cross arm 9 are fixed by an M10 hexagon head bolt 5 and an M10 hexagon nut 4. Each equipment support cross arm 9 is provided with two holes for installing M10 suspension wires 10 for equipment hoisting, the distance L between the two holes is consistent with the distance between two transverse lifting lugs 11 of the multi-split equipment, and the M10 suspension wires 10 are fixed on the equipment support cross arms 9 by using two M10 hexagon nuts 4. Each multi-connected lifting lug 11 is fixed at the lower end of the M10 suspension wire 10 by an upper M10 hexagonal nut and a lower M10 hexagonal nut, and four lifting lugs of the multi-connected equipment are connected in the method, so that the equipment is lifted.

The multi-online equipment support is an essential accessory for normal installation of equipment. The angle steel with proper length is cut out from the materials used for installing the multi-split air conditioner equipment support according to the transverse size of the multi-split air conditioner to serve as the equipment support cross arm 9, and holes are drilled on the cross arm according to the distance between the multi-split air conditioner lifting lugs and used for installing the equipment lifting wires. The cross arms and the triangular supports are fixed by bolts and nuts of M10, and the distance between the two cross arms is consistent with the width of the multi-connected wire. And mounting the processed bracket on the H-shaped steel structural column by adopting a hoop mounting mode, and fixing by using a bolt M12. When the multi-split air conditioner is installed, due to high-altitude operation, the safety of operators must be guaranteed, and safety belts and safety helmets must be worn during operation. After the equipment is installed on the support, the levelness of the equipment is controlled by the leveling rod, the equipment is in a horizontal position by adjusting the length of the suspension wire, and then the installed equipment is protected.

Secondly, installing a multi-split pipeline steel cable:

the installation is transversely laid along the steel structure post to the many online pipeline cable wire, and the material that the many online pipeline cable wire installation was used includes: m12 hex bolts 1, M12 hex nuts 2, steel clamping plate 12, basket bolts 13, steel cable 14, steel cable clamp 15, support base 16, support arm 17, L-shaped clamping lug 18, M8 hex head bolts 19 and steel cable clamp nuts 20. Two holes are formed in the inner side plate of the steel clamping plate 12 for installing the M12 hexagon nut 2, and a hole is formed in the outer side plate of the steel clamping plate 12 for fixing the steel cable 14. Two M12 hexagon nuts 2 are welded at two holes of the inner side plate of the steel splint 12, the steel splint 12 is buckled at the edge of the flange plate of the H-shaped steel structure column, and the steel splint 12 is firmly fixed on the H-shaped steel structure column by using M12 hexagon head bolts 1 and M12 hexagon nuts 2. The T-shaped steel cable support is manufactured by welding a support base 16 and support arms 17, two holes are formed in two ends of the support base 16 and used for fixing L-shaped clamping lugs 18, and a steel cable support hoop is installed on a steel structure column through an M8 hexagon head bolt 19 and matched nuts. Two holes are arranged on the bracket arm 17 according to the distance between two legs of the steel cable clamp 15 for installing the steel cable clamp 15. The ends of the cable 14 are connected to the steel clamp plate 12 by means of the turn buckle 13, and the cable 14 is clamped to the bracket arms 17 by means of the cable clamp 15 and the cable clamp nut 20 as the cable 14 passes through the cable bracket. The looseness of the steel cable 14 is adjusted by adjusting and changing the length of the turn buckle 13, so that the elasticity of the steel cable 14 tends to be proper.

The multi-split pipeline is transversely paved and installed along the steel structure column, so that the steel cable is also transversely installed along the steel structure column. The total length of the multi-split air-conditioning system pipeline is 114 meters, the condition that the equipment pipeline does not sink at the middle position is difficult to guarantee only by fixing two ends of the steel cable, and in order to meet the requirement of the appearance quality that the mounted multi-split air-conditioning system pipeline is horizontal, flat and vertical, a steel cable support is arranged on each steel structure column and used for supporting and fixing the whole steel cable.

The installation mode of the steel cable bracket and the steel clamping plate is fixed by the hoop installation mode, and the hoop is fixed by the hexagon head bolt, the nut and the matched auxiliary lifting lug. The steel clamping plates at two ends and the steel cable bracket in the middle are hooped on the steel structure column, and all the steel cable brackets and the steel clamping plates are positioned on the same horizontal line after installation. The steel clamping plates 12 are respectively installed on the steel structure columns at the two ends of the multi-split pipeline in a hoop installation mode, the two steel clamping plates 12 are used as supporting points for horizontal stretching of the steel cable, and the two ends of the steel cable 14 are connected with the steel clamping plates 12 through turn buckle bolts. Because the steel cable 14 has certain elasticity, the turnbuckle can adjust the looseness of the whole steel cable 14, straightens the steel cable 14 to the maximum extent, and avoids the middle part of the steel cable from sinking. The cable is fixed by the cable clamp 15 when passing through the cable bracket, on one hand, the cable is used for ensuring that the installed cable cannot swing left and right, and on the other hand, the cable is used for dispersing the tension of the cable on the steel clamping plates 15 at two ends.

Three, multi-online pipeline rings installation

After the steel cable is installed, the multiple online pipeline hanging rings are reasonably and uniformly arranged and installed according to the distance between the two structural columns, each hanging ring is composed of an upper layer hanging ring 21 and a lower layer hanging ring 22, the upper layer hanging rings 21 are used for supporting multiple online refrigerant pipes 23, and the lower layer hanging rings 22 are used for supporting multiple online condenser pipes 24.

The distance between two steel structure columns is 6 meters, the distance between two steel cable supports is also 6 meters, and the support of big span can't satisfy the normal installation of multi-connected refrigerant pipe and condenser pipe, consequently need add the pipeline hoisting point on the cable wire between two steel cable supports, can not sink because of self gravity after messenger's refrigerant pipe and condenser pipe installation. In order to realize the aesthetic property and usability of the finished product pipeline after installation, 3 lifting points are additionally arranged, 6 meters are divided into four sections, and each 1.5 meter is provided with a lifting ring. A group of lifting rings are arranged on the steel cable at equal intervals, two lifting rings are arranged up and down, the multi-split refrigerant pipe is arranged in the upper layer lifting ring 21, and the condensation pipe is arranged in the lower layer lifting ring 22.
