Abstract

The invention provides a one-side fastening bolt. The one-side fastening bolt comprises a screw and a conical head at one end of the screw; the conical head is integrated with the screw; the screw issequentially provided with a sleeve, a fixing gasket and a nut in a penetrating manner from the conical head end; and the sleeve and the fixing gasket are in clearance fit with the screw, the outer diameter of the sleeve is greater than the inner diameter of the fixing gasket, the sleeve is provided with a plurality of axial openings close to the conical head end, the smaller end of the conical head is clamped into the sleeve, and the outer diameter of the larger end of the conical head is greater than or equal to the inner diameter of the sleeve. On the premise of not reducing the installation speed and the joint strength, the one-side fastening bolt avoids the situation that a traditional method causes opening weakening of a connection section when completing bolt connection of closed-section components; and the one-side fastening bolt has the advantages of being convenient and fast to install, adapting to connection of the closed-section components, reducing the requirement for theout-of-plane height of an inaccessible side, guaranteeing the integrity of the connection section and the like.

Description

technical field [0001] The present application relates to the technical field of component connection, in particular to a unilateral fastening bolt for connecting two components, one of which is a closed interface. Background technique [0002] In steel structures or composite structures, the connections between steel members are generally welded, riveted, and bolted. Welding connection is the most important connection method for steel structures. Its advantages are simple structure, no weakening of the construction section, steel saving, convenient processing, easy automation, good sealing performance and high rigidity; the advantages of rivet connection are plasticity and toughness. It is better, reliable in force transmission, and easy to check in quality. It is suitable for the connection of structures directly bearing dynamic loads. The disadvantage is that the structure is complex and the amount of steel is large, so it is rarely used at present; and the bolted connect...
