Problems solved by technology

This connection and fastening method has simple structure, convenient operation and good load bearing, but it is only suitable for open cross-section components. In some special occasions, such as connecting and fastening closed cross-section components or components that are inconvenient to operate on the other side , it is impossible to use this commonly used bolt and nut connection fastening method
For example: in the steel pipe structure and steel pipe concrete structure, at the joint of the beam column, because the steel pipe column is a closed section, it cannot be operated on both sides, and can only be connected and installed on one side, so this commonly used bolt and nut connection fastening method cannot be used For fast installation
At present, th

Abstract

The invention relates to an installation tool for a split type nesting unilateral fastener. The installation tool for the split type nesting unilateral fastener can achieve the function of simultaneously installing a plurality of split type gaskets, and comprises a rubber sleeve, split type gasket operation rods, an installation plate, guide plates, sliding blocks, connecting rods, a buttonhead gasket operation rod and a hand-pushing sliding block. The split type nesting unilateral bolt fastener is composed of a buttonhead, the split type gaskets, a flat gasket and a nut. Through the method that the hand-pushing sliding body drives the connecting rods to drive the multiple sliding blocks to synchronously expand, and the multiple split type gaskets are guided and expanded to the inner side of an installation hole wall with relatively narrow space. The installation tool can achieve rapid and efficient installation work of the split type nesting unilateral fastener, brings convenience to batch operation on a construction and industrial site, and is convenient to detach and capable of being used repeatedly.

Description

technical field [0001] The invention relates to a bolt fastener installation tool which can be used for unilateral installation in the connection and fastening of structural parts, and belongs to the technical fields of civil engineering and mechanical assembly. Background technique [0002] At present, in the field of civil engineering and mechanical installation, there is a large demand for the installation of connection and fastening of structural parts. As far as bolts are commonly used at present, when performing connection and fastening operations on components, workers need to work on both sides of the component at the same time, that is, insert a bolt with a nut on one side, and then use a tool to tighten the nut on the other side . This connection and fastening method has simple structure, convenient operation and good load bearing, but it is only suitable for open cross-section components. In some special occasions, such as connecting and fastening closed cross-se...
