Description

A light steel keel assembled wall with shielding function

technical field

The utility model relates to a wall body, in particular to a light steel keel assembled wall body with a shielding function.

Background technique

Secondary control equipment and communication equipment in the fields of electric power and communication are sensitive to external electromagnetic interference. If they are subjected to external electromagnetic interference, it will cause equipment malfunction and affect the normal operation of the entire system, resulting in interruption of power supply and communication services. Therefore, communication equipment rooms and relay protection control rooms in industries such as electric power and communication require electromagnetic shielding measures, but professional shielding rooms are relatively expensive to build and have high operation and maintenance costs. The relay room, main control room, etc. in the building are only sensitive to interference of a certain band, so there is no need to use a professional shielding room. The shielding method of the above-mentioned equipment room is generally realized by laying steel wire mesh on six sides of the wall, floor, and ceiling, and then grounding it as a whole.

In response to the country's call for innovation and green environmental protection, the power system has introduced a series of measures in recent years. The prefabricated substation is one of them. All building components and equipment are assembled on-site in the factory to reduce noise and dust caused by on-site operations. and other environmental pollution problems, and shorten the construction period. The decentralized relay cell of the 500kV substation is in the form of a light steel keel-assembled wall assembly. In order to avoid misoperation of the equipment caused by external interference, a shielding net is required in the room. Combined with the characteristics of the light steel keel-assembled wall system, the shielding The net is clamped between the inner wall panel and the outer wall panel and welded with the supporting light steel keel in the wall. However, the shielding metal mesh at the joints of this method is prone to elastic concave-convex deformation after being squeezed, resulting in uneven heights of the fixed points of the wall panels and uneven joints between the panels, resulting in deformation of the wall, affecting the appearance of the wall and even affecting the appearance of the wall. Normal use.

Detailed ways

Embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings.

Fig. 1 shows the structure diagram of one embodiment of the light steel keel assembled wall of the present invention, which mainly consists of light steel keel, outer wall panel 7, inner wall panel 4, flat gasket 1 and shielding metal mesh 3 Composition, the light steel keel includes the main light steel keel 5 arranged vertically, the outer wall panel 7 is fixed on the outside of the light steel keel by screws 6, the inner wall panel 4, the flat gasket 1 and the shielding metal mesh 3 are fixed by screws 2 Fixed on the inner side of the light steel keel. The flat gasket 1 is located between the inner wall panel 4 and the shielding metal mesh 3 . By setting the leveling gasket 1 between the shielding metal mesh 3 and the outer wall panel 7 or the inner wall panel 4, the deviation of the flatness of the wall is controlled within 3 mm, which can meet the requirements of the "Quality Acceptance Code for Building Decoration Engineering", It overcomes the unevenness and cracking of the light-weight light-weight steel keel wall due to the shielding net. Moreover, since the light steel keel is the load-bearing frame of the wall, but it is also a weak link for fire protection, the flat gasket of the light steel keel wall shielding net is laid along the vertical length of the main light steel keel, and is more horizontal than the light steel keel Wide, it protects the main light steel keel and greatly increases the fire performance of the wall.

The leveling gasket 1 adopts a new environmentally friendly reinforced cement fiber board, which has the characteristics of high strength, no deformation, and good fire resistance, and the leveling gasket 1 of other materials can also be used. The width and thickness of the flat gasket 1 are calculated and determined according to the distance between the light steel keels, and the principle is to ensure that the bending deformation of the inner wall panel 4 is within the scope specified in the acceptance specification. Usually, the thickness of the flat gasket 1 is required to be greater than 12mm, and its width in the horizontal direction is required to be greater than the width of the main light steel keel 5 . As another embodiment, the size of the leveling gasket 1 matches the size of the shielding metal mesh 3 , that is, the leveling gasket 1 is in the form of a full-floor board.
