Construction method of steel frame partition

1. The most important point of the channel steel floor is the fixing of the two ends of the channel steel. There are three main types of fixed methods:

1. Use the angle steel to make a support frame on the wall, lock it on the wall with the expansion screw, then fix it on the top with channel steel, and also use the planting bar to directly fix the channel steel. This method is only limited to the wall at the two ends, which is a load-bearing wall or just crossing a beam. It is fixed on the wall with expansion screws, and the interval between expansion screws is no more than 200mm.

First, a hole in the wall, then the channel steel into the wall, and the wall directly bear the weight of the channel steel.

This method is limited to a load-bearing wall or a thicker shear wall.

The other channel steel is directly erected to support the transverse channel steel, and the vertical channel steel should be fixed to the wall.

This method should consider the load-bearing capacity of the floor with the location of the vertical channel steel. It should be distributed more support and do not concentrate on a few channel steel. The third way requires channel steel instead of the angle steel as the first one. It is usually fixed on the longest side, and if the longest side is not fixed in parallel, it can also be laid on the shortest sides.

2, to solve the fixed point of the channel steel, the following is to solve the main choreography of the main keel. Generally speaking, for the living room, it is suggested that the main keel can be used as the channel steel of 120 x 60 x 6mm or above. The main keel should be paved parallel to the shortest side, at a interval of about 500mm.

The channel steel must be placed above the wall, and the gap between the wall and the wall is not more than 10mm. A full weld to the rungs on the channel. If there is no fixed condition in parallel to the shortest side, it can be laid parallel to the longest side.

3, then weld the accessory keel between the main keel. The accessory keel can be made of equal side angle steel with 50x50x4mm or above specifications. The auxiliary keel is full of welding on the main keel, the plane is the same, and it is perpendicular to the main keel. The suggestion value of the arrangement interval is 300mm (maximum value), it should be tight and unsuitable. For safety, it is advisable to weld a small section of corner steel in the lower part of the sub - keel and the main keel, so as to make it safe.

4, welded railing or staircase. The railings and staircases can only be welded on the main keel, and must be fully welded 5, and then sandpaper is used to grind the rusty and serious position. Then all the channel steel and angle steel can be coated or coated with antirust paint. After it is dry, and then coated with a layer of enamel, enamel colors can be chosen freely.

6. A layer of 15 mm splint is laid on the skeleton, and the splint can be fixed on the accessory keel with a pull pin (rivet). On the splint, we lay 12 more large core boards (Blockboard). The gap between the two boards must be staggered. The core board must be fixed on the splint, and the nail will be done directly. If you don't want to use a splint, if the density of the sub keel is dense enough, a layer of steel grid is laid on the top. Even the thin steel bar and cement can be used to irrigate a floor with a thickness less than 50mm. The sloshing sound of the floor slab used for cement irrigation is lower than that of the splint, but the possibility of a certain number of cracks will occur when the cement is poured.

It must ensure that the ratio of cement mortar and mixed with enough steel.

7, the laying of other surface materials, such as solid wood floors, carpets or ceramic tiles (floor slab for cement irrigation).

8. Precautions

1, if you have no confidence on the fixed channel, must be installed in vertical to the position of the rail channel support has rung, in the case of a fixed,

Not every main keel needs the vertical support of the channel steel, not more than 6 meters.

There are two or three supports on the side.

2, is the two section of the strip itself is not welded, must be long development.
