Problems solved by technology

This construction process has many welding points, difficult construction and long construction period. The most important thing is that the galvanized layer of the lightning-terminating zone is damaged in a large area, which can easily lead to corrosion of the lightning-terminating zone and shorten the service life, thus affecting the entire lightning protection grounding system

Embodiment 1

[0024] Embodiment 1 Basic Reference figure 1 As shown in , the installation process of surface-mounted lightning-termination belt supported by casing includes the following steps:

[0025] A. Manufacture of the casing bracket: Cut the material according to the schematic diagram of the casing bracket, intercept the galvanized round steel with a length of 230mm: the height of the exposed parapet is 150mm, the depth of the buried parapet is 80mm, the length of the galvanized steel pipe is 50mm, and the burrs are polished After that, after the preliminary welding process is completed, it will be sent to the factory for hot-dip galvanizing treatment;

[0026] B. Sleeve support positioning: Set the end point sleeve support on the wall at a distance of 300mm from the corner at both ends of the horizontal straight line section of the wall, and install the sleeves in the middle section between each two end points. The distance between brackets and casing brackets shall be 70mm; after ...

Embodiment 2

[0029] Example 2 reference figure 2 As shown, compared with Embodiment 1, the difference is that the decorative cover is slidably connected to the support column, and the support column is located below the decorative cover and is slidably connected with the first wedge, and the top of the decorative cover is against the top of the first wedge. A fixed block is welded on the support column below the first wedge, a first spring is welded between the first wedge and the fixed block, an opening is opened on the support column between the first wedge and the fixed block, and the sliding connection extension in the opening is The second wedge comes out of the opening, the second wedge is against the first wedge, the second spring is welded between the second wedge and the opening wall, and the top of the decorative cover is provided with a limit for the insertion of the second wedge hole.

[0030] After fixing the support column on the wall, slide the decorative cover downwards, ...

Embodiment 3

[0031] Example three reference image 3 As shown, compared with Embodiment 1, the difference is that an expansion bolt is installed at the bottom of the support column, and the expansion bolt includes a screw rod, a nut, an expansion sleeve and a fixed sleeve, the bottom of the support column is a screw rod, and the nut is threaded on the screw rod. The bottom is welded with a fixed sleeve, and an expansion sleeve is set between the fixed sleeve and the nut.

[0032] Insert the expansion bolt at the bottom of the support column into the installation hole, screw the nut of the expansion bolt, the expansion sleeve of the expansion bolt will expand and perform interference fit with the wall of the installation hole, so that the support column is fixed.

[0033] Embodiment 4-embodiment 7, compared with embodiment one, its difference is, as shown in the table below:

Abstract

The invention discloses an installation construction technology of an open mounted lightning receiving strip supported by a casing pipe. The installation construction technology comprises the following steps that A, a casing pipe support is manufactured; B, the casing pipe support is positioned; C, the casing pipe support is installed; and D, the lightning receiving strip is installed. According to the scheme of the installation construction technology, compared with the prior art, a supporting column, the casing pipe and an antirust layer are only needed, then manufacturing and forming are achieved, manufacturing is easy, construction is convenient, and good practicability is achieved; the lightning receiving strip is supported and fixed by penetrating through the casing pipe, welding construction between the lightning receiving strip and the supporting column is omitted, meanwhile the processes of antiseptic treatment, finishing coat treatment and the like of a supported point of thelightning receiving strip are further omitted, the construction cost is reduced, the construction work efficiency is improved, and the economic benefits are obviously improved; the later maintenanceworkload is reduced through arrangement of the antirust layer, and the service life of the lightning receiving strip is prolonged; and when being installed, the lightning receiving strip can extend and retract left and right in the casing pipe, the problem of welding prestress caused by welding of the lightning receiving strip and the supporting column is solved, the straightness of the lightningreceiving strip is ensured, and the appearance quality of the lightning receiving strip is improved.

Description

technical field [0001] The invention relates to the field of building lightning protection systems, in particular to the installation and construction technology of surface-mounted lightning-termination belts supported by bushings. Background technique [0002] The air receptor plays a decisive role in the entire lightning protection system, and its importance is self-evident. The traditional construction of the air-termination device adopts the welding process, that is, the air-termination belt and the bracket are welded and fixed. This construction process has many welding points, difficult construction and long construction period. The most important thing is that the galvanized layer of the lightning-terminating zone is damaged in a large area, which can easily lead to corrosion of the lightning-terminating zone and shorten the service life, thus affecting the entire lightning protection grounding system. Contents of the invention [0003] The object of the present i...
