Abstract

The invention discloses an insulating installation structure for installing a cable tray in an electrolysis workshop. Corresponding holes are arranged on a concrete wall or concrete floor slab according to the distances of the bolt holes of an insulation board; the depth and aperture of the holes are matched with anchor bolts; the insulation board is arranged on a fixing surface; the base of a steel strut abuts against the insulation board; and the bolt holes of the insulation board are corresponding to the bolt holes of the base; the anchor bolts are sleeved with insulation linings; the anchor bolts penetrates into the bolt holes and are inserted into the concrete wall or concrete floor slab; insulation washers and flat washers sleeve the anchor bolts and are fixed through nuts; and insulation sleeves sleeve the nuts and the flat washers. According to the insulating installation structure of the invention, a totally enclosed structure is adopted; the same insulating material is adopted, so that the widening of gaps between components due to the differences of materials under the same ambient temperature can be avoided, and therefore, the steel cable tray can be reliably insulated from the concrete reinforcing bars of a civil construction structure when the steel cable tray is installed in the electrolysis workshop.

Example Embodiment

[0017] The present invention will be described in detail below with reference to the drawings, such as figure 1 , figure 2 As shown, corresponding holes are arranged on the concrete wall or concrete floor 10 according to the distance between the bolt holes of the insulating plate 5, and the depth and diameter of the holes match the anchor bolt 6; the insulating plate 5 is arranged on the fixed surface, and the steel pillar 7 The base 71 of the insulating plate abuts against the insulating plate 5, and the bolt holes of the insulating plate 5 correspond to the bolt holes of the base 71; the anchor bolt 6 is covered with an insulating bushing 2, and the anchor bolt 6 penetrates each bolt hole and is inserted into the concrete wall or concrete floor 10 In; the insulating washer 1, the flat washer 3 are sleeved on the anchor bolt 6, and then fixed with a nut; the insulating sleeve 4 is sleeved outside the nut and the flat washer 3.

[0018] A bridge support arm 8 is provided on the steel pillar 7, and a steel cable bridge 9 is installed on the bridge support arm 8.

[0019] The present invention mainly includes the following components:

[0020] 1. Insulating gasket:

[0021] The insulating gasket is a circular gasket with an outer diameter of 50mm, a center inner diameter of 23mm, and a thickness of 4mm. The material is UPM203. UPM203, also known as GPO-3, refers to the unsaturated polyester fiberglass mat material. The main function is to provide insulation between the base of the steel pillar and the anchor nut.

[0022] 2. Insulation bushing:

[0023] The insulating bushing is a short tube with an outer diameter of 22mm and a wall thickness of 2.5mm and a length of 19mm, made of UPM203. The main function is to provide insulation between the base of the steel pillar and the anchor bolt.

[0024] 3. Flat washer:

[0025] The flat washer is a 200HV standard washer made of GB/T97.1M16. The main function is to provide the connection and installation of the nut and the anchor bolt.

[0026] 4. Insulation sleeve:

[0027] The insulating sleeve is a U-shaped head with an outer diameter of 37mm and an inner diameter of 28 and a length of 55mm, made of UPM203. The main function is to provide insulation for anchor bolts and nuts.

[0028] 5. Insulation board:

[0029] The insulating plate is a 320x320mm square plate with a thickness of 5mm, with 4 bolt holes 24mm in diameter, made of UPM203. The main function is to provide insulation between the base of the steel pillar and the concrete wall and floor.

[0030] 6. Anchor bolt:

[0031] The anchor bolt is FZA type rear-expanded column cone type standard anchor bolt, matching bolts and nuts. The main function is to provide the connection and installation of the steel pillar base and the concrete wall and floor.

[0032] The specific construction steps are as follows:

[0033] 1) During construction, determine the laying and installation method of the cable tray according to the specific conditions of the site, and determine the laying along the wall or the hoisting under the floor.

[0034] 2) Determine the number of supporting points according to the laying path and length, and make corresponding insulating washers 1, insulating bushes 2, flat washers 3, insulating sleeves 4 and insulating plates 5 in large quantities.

[0035] 3) When installing, firstly drill corresponding holes on the concrete wall or concrete floor 10 according to the distance of the bolt holes of the insulating plate 5 with a percussion drill, and the depth and diameter of the hole match the anchor bolt 6. Firstly, the insulating plate 5 is placed on the fixing surface, and then the base of the steel pillar 7 is pressed, and the bolt holes of the insulating plate 5 are corresponding to the bolt holes of the base of the steel pillar 7. Put the insulating bushing 2 on the anchor bolt 6, then insert the anchor bolt 6 into each bolt hole, insert it into the concrete wall or concrete floor slab, and fix the insulating board 5 and the steel pillar 7 well. Put the flat washer 3 on the anchor bolt 6, and then fix the anchor bolt 6 on the concrete wall or concrete floor with nuts. Put the insulating sleeve 4 on the nut and the flat washer 3.

[0036] 4) You can repeat the content of the implementation in step 3 as needed, and continue to complete the laying and installation of other columns.

[0037] 5) Install the bridge support arm 8 on the steel pillar 7, and install the steel cable bridge 9 on the bridge support arm 8, and finally complete the installation of the bridge.
