Abstract
The invention relates to a building construction method, in particular to a method for mounting an explosion-proof lamp on a large-space grid structure. The aim of mounting of explosion-proof lamps of coal storage plants is achieved. The method includes the steps that 1, an explosion-proof junction box is connected with galvanized steel guide tubes through explosion-proof movable joints; 2, the electrical galvanized steel guide tubes are fixed to a lower chord of a grid through connecting pieces, tube clamps and nuts; 3, the explosion-proof lamp is fixed to the galvanized steel guide tubes through explosion-proof movable joints; and 4, the galvanized steel guide tubes are extended and fixed, the steps 1-3 are conducted repeatedly, and a cable or wire is led into the explosion-proof lamp through one galvanized steel guide tube, the explosion-proof junction box and the other galvanized steel guide tube. The construction method combines firm mounting with the explosion-proof demand of the lamp, thereby effectively achieving the technical aim of mounting the explosion-proof lamp on the large-space grid structure.

Detailed description of the invention
A kind of large space network frame structure explosion-proof lamp installation method, step is 1. coupled together by anti-explosion movable joint and galvanized steel conduit by anti-explosion terminal box; 2. brace, pipe clamp, nut is used to be fixed on rack lower boom by electric galvanized steel conduit; 3. explosion-proof lamp is fixed on galvanized steel conduit by anti-explosion movable joint; 4. extend galvanized steel conduit and fix, repeating 1. ~ 3. step; Finally cable or electric wire are introduced explosion-proof lamp through galvanized steel conduit, anti-explosion terminal box, galvanized steel conduit.
The concrete practice is,
As schematically shown in Figure 1, one, anti-explosion terminal box 4 and galvanized steel conduit 1 is connected
1) use pipeline die head threading machine that three 500mm long DN25 galvanized steel conduit 1 two ends are processed as standard pipe thread respectively.
2) the externally threaded DN25 anti-explosion movable joint in internal thread one end, one end is selected;
3) unclamp anti-explosion movable joint locknut, anti-explosion movable joint is split into two parts;
4) female for band part 2 is threaded with galvanized steel conduit;
5) will be threaded with anti-explosion terminal box with externally threaded part 3.
Finally form structure as schematically shown in Figure 2,
Two, anti-explosion terminal box 4 and galvanized steel conduit are fixed on rack lower boom 10
As schematically shown in Figure 3, connector 5 is made
Connector 5 adopts the galvanized steel plain sheet of long 340mm, wide 70mm, thick 10mm to make; Bench drill is used to process 4 round holes between two parties according to size.
As schematically shown in Figure 4, DN100 pipe clamp 9, DN25 pipe clamp 8, brace 5, M16 hex nut, M10 hex nut is used the galvanized steel conduit connected, anti-explosion terminal box to be fixed on rack lower boom 10.Brace 5 is no more than 100mm apart from anti-explosion terminal box 4.
