Steel structure partition channel steel construction scheme

The construction scheme of steel structure partition channel steel is very important, we combine professional knowledge and actual situation. Today, I will explain to you the construction plan of steel structure partition channel steel.
1. The key point of channel steel is the fixing of both ends of the channel steel. There are three main fixing methods: one is to make an angle steel on the wall, lock it on the wall with expansion screws, and then fix it with channel steel, or it can be fixed by planting bars. This method is only limited to the place where the walls at both ends are load-bearing walls or just where the beams pass, and they are fixed on the wall with expansion screws, and the interval between the expansion screws does not exceed 200mm. The other is to punch a hole in the wall first, then extend the channel steel into the wall, and the wall directly bears the weight of the channel steel. This method is limited to load-bearing walls or thick shear walls. Another method is to directly erect another channel to support the horizontal channel, and the vertical channel should be fixed on the wall. This method needs to consider the load-bearing capacity of the floor where the vertical channel steel is located. It should be supported at multiple points, and the force should not be concentrated on a few channel steel to bear. The third method requires the use of channel steel, not like that Just use angle steel. It is generally fixed on the long two sides. If the long two sides are laid in parallel and there is no fixed condition, it can also be laid with the short two sides.
2. The fixed point of the channel steel is solved, and the next thing to be solved is the arrangement of the main keel. Generally, for the living room, it is recommended to use channel steel with a size of 120×60×6mm or above as the main keel. The main keel should be laid parallel to the short side with an interval of about 500mm. The channel steel must be placed on the wall, and the gap with the wall should not exceed 10mm. The channel steel is fully welded on the crosspiece. If there is no fixed condition for laying parallel to the short side, it can also be laid parallel to the long side.
3. Weld the auxiliary keel between the main keel. The auxiliary keel can be made of equilateral angle steel, and the specification is 50x50x4mm or more. The auxiliary keel is fully welded on the main keel, the plane is the same, and it is perpendicular to the main keel. The recommended value of the arrangement interval is 300mm, which should be dense and not sparse. For the sake of safety, it is advisable to weld a small piece of scrap of angle steel at the lower part between the auxiliary keel and the main keel for safety.
4. Weld railings or stairs. Railings and stairs can only be welded above the main keel and must be fully welded.
5. Then sand the severely rusted position with sandpaper, and then use anti-rust paint to coat all the channel steel and angle steel once or more. After it is dry, apply a layer of enamel paint, and the color of the enamel paint can be freely chosen.
6. Lay a layer of 15 cm plywood on the skeleton, and the plywood can be fixed on the auxiliary keel with pull studs (rivets). Lay a layer of 12 cm large core board (blockboard) on top of the plywood. The position of the gap between the two layers of boards must be staggered. The large core board must be fixed on the plywood and nailed directly. If you don't want to use plywood, if the density of the auxiliary keel is dense enough, after laying a layer of steel grid on it, you can even use fine steel bars and cement to pour a floor slab with a thickness of no more than 50mm. The swaying sound of the floor slab poured with cement is lower than that of the plywood, but there may be a certain number of cracks in the slab poured with cement. At this time, it is necessary to ensure that the proportion of cement mortar and enough fine steel bars are mixed.

7. Lay other surface materials, such as solid wood floors, carpets or ceramic tiles (limited to cement-filled floors).
