Introduction to all steel anti-static floor

The all-steel anti-static raised floor is made of high-quality alloy cold-rolled steel plate (Shanghai Baosteel), which is formed by spot welding after stretching.

The surface is phosphatized and subjected to electrostatic spray treatment. The inner cavity is filled with 425# standard pure cement, and the upper surface is pasted with high wear-resistant fireproof high-pressure laminate (HPL) or (PVC) plate (no veneer is bare). Sidebar. Anti-static ceramic tile can also be applied to the surface to form an anti-static ceramic-metal composite raised floor.

Steel Bolt

Bolt is a kind of fastener which consists of head and screw (cylindrical body with external thread) . It should be used with nut for fastening two parts with through hole, an Anchorage Assembly that anchors the connector to a hardened concrete substrate.

Because the bolt is also a kind of railway accessories, railway accessories is a part of the railway line, here refers to the track including steel rails, sleepers, connecting parts, bed, anti-climbing equipment, rail support and turnout, etc. . As a whole engineering structure, the track laid on the roadbed plays a guiding role in train operation and bears the huge pressure of the locomotive and its load directly. Under the dynamic action of the train, its components must have enough strength and stability to ensure the train to run safely, smoothly and continuously in accordance with the prescribed maximum speed. Main classifications are general and hinged according to the manner in which the joints are loaded. The ordinary main load bearing axial force, but also can bear the lateral load demand is not high. Bolts for reaming holes shall be fitted to the hole dimensions and shall be used when subjected to lateral forces. According to the shape of the head is divided into hexagon head, round head, square head, heavy head and so on. The hexagonal head is the most commonly used. The countersunk head is usually used where a smooth, raised surface is required after joining, because the countersunk head can be screwed into the part. The round head can also be screwed into the part. The tightening force of the square head can be greater, but the size is very large. In addition, in order to meet the needs of locking after installation, there are holes in the head, rod hole, these holes can make the bolt vibration not loose. Some bolts do not thread bare rod to do fine, called fine waist bolt. This bolt is advantageous to the connection subjected to variable forces. There are special high-strength bolts on the steel structure, the head will be bigger and the size will change. Also has the special use: T-slot Bolt, the machine tool fixture with the most, special shape, the head of both sides to be cut off. Anchor Bolts, used for machine and ground connection and fixation, come in a variety of shapes. U-BOLTS, as described above. Wait a minute. There are special welding stud, one end has a thread, one end is not, can be welded on the parts, the other side directly screw nut. The U-BOLT is a non-standard part. It is also called U-bolt because of its u-shaped shape. The two ends of the bolt can be combined with a nut. It is mainly used to fix the leaf spring of a tubular object such as a water pipe or a piece of material such as a car, it is called a riding bolt because it fastens the object in the same way that a man rides a horse.
