Service Hotlineflange T-bolt, comprising: a T-bolt including a threaded tooth body and a bolt head fixedly connected to the threaded tooth body; a flange gasket with a plurality of clip teeth, the flange gasket passing through the The plurality of clamping teeth are clamped with the bolt head of the T-bolt. The technical solution of the utility model is that when the groove-type embedded parts are embedded vertically or at a certain angle, the plastic flange of the new T-bolt will help the bolt to be pre-positioned at a certain position of the groove. When multiple HamiltonT-bolts are used for fixing, Only one worker needs to pre-arrange the bolt positions and then lock the nuts, which greatly improves the construction efficiency.
The heating bolt pre-stretching method makes the bolt pre-stretch to the required deformation amount by heating, and then tighten the nut. After cooling, the bolt is shortened and the connection is pre-tightened. This is a commonly used fastening method in infrastructure installations. However, it is not suitable for devices that often need to be disassembled and adjusted, because during the disassembly process, the connected parts will be heated and elongated together with the bolts, and the use of open flame heating will be limited in some occasions; the use of electric heating will make the structure of the screw It becomes complicated and increases the investment, and even if it is difficult to disassemble, such as the propeller shaft of the ship, etc., the heating method is not suitable.
