Description

Auxiliary mounting tool for split type gasket elastic fixing ring

Technical Field

The invention relates to an auxiliary mounting tool, in particular to an auxiliary mounting tool for a split type gasket elastic fixing ring.

Background

Currently, in the fields of civil construction and mechanical installation, the installation requirement for connecting and fastening structural components is large. In the case of bolts which are currently in common use, when fastening and connecting members, workers need to work on both sides of the members at the same time, namely, insert a bolt with a nut on one side and then tighten the nut with a tool on the other side. The connecting and fastening method has simple structure, convenient operation and good bearing capacity, but is only suitable for the members with the open cross sections, and the common bolt and nut connecting and fastening method cannot be used in some special occasions, such as the connecting and fastening of the members with the closed cross sections or the members inconvenient to operate at the other side. Such as: in steel pipe structures and steel pipe concrete structures, beam column connection nodes cannot be fastened and installed by the common bolt-nut connection fastening method because steel pipe columns are closed sections and cannot be operated on two sides and can only be connected and installed on one side. At present, corresponding unilateral bolt products are not available in domestic markets, published related patents have similar products in foreign markets, namely too much weakening of a bolt rod or too few stress points of a bolt head, but the existing patents or products are difficult to apply large pretension force to the bolt in the installation stage to form a friction type bolt connecting joint, the bearing comprehensive mechanical property of the joint is not ideal, and the joint is greatly limited in application of building structure earthquake-resistant design.

Chinese patent with patent application publication No. CN 108571505a discloses a deformation contraction self-recovery split type unilateral bolt fastener and mounting tool thereof, and the structural characteristics of the unilateral bolt fastener disclosed in the patent are: the split gaskets are connected into a whole through elastic fixing rings (such as rubber bands) to form the self-recovery split gasket capable of deforming and contracting.
