Problems solved by technology

However, due to the disadvantage of slippage, the pressure-bearing high-strength bolt connection can only be applied to the connection of structures bearing static loads or indirect dynamic loads, and is not suitable for the connection of braking systems or important structures bearing dynamic loads.

Embodiment Construction

[0017] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] As shown in the drawings, a self-compacting wedge-shaped split-type pressure-bearing high-strength bolt connection node of the present invention includes two splicing plates 2 arranged in parallel and opposite intervals on the upper and lower sides, and a left side of the connected plate 1. The right end and the left end of a right side connected plate 1 are respectively arranged between the upper and lower two splicing plates 2, and the left end of the two splicing plates 2 and the left end of the connected plate 1 The right end of the left side is respectively opened with the left reserved hole along the same vertical axis, and the right end of the two splicing plates 2 and the left end of the connected plate 1 on the right are respectively opened with the right side reserved hole along the same vertical axis. holes, th...

Abstract

The invention discloses a connecting joint for self-compaction wedge-shaped spliced type pressure-bearing type high-strength bolts. A wedge-shaped screw of the connecting joint and a wedge-shaped screw with a nut are each provided with a certain number of gaskets. When the bolts are screwed down and pre-tension force is exerted, pressing force is generated between contact surfaces of connected plate pieces, and the bolts are tensioned axially, so the wedge-shaped screw and the wedge-shaped screw with the nut relatively slide, the actual diameter of the bolts is accordingly increased, the gaps,in the tension direction of the connected plate pieces, between reserved bolt holes and the bolts are filled. After the connected plate pieces are connected, the gaskets should make sectional weakened sections of the screws located on the upper side and the lower side of upper and lower spliced plates respectively, so the non-sliding connecting joint suitable for steel structure connecting partsfor bearing the reciprocating load effect in the tension direction of the connected plate pieces is formed.

Description

technical field [0001] The invention belongs to the scope of connection engineering of steel structures, and in particular relates to a connection node of a self-compacting wedge-shaped combined pressure-bearing high-strength bolt applied to steel structure connection projects such as industrial and civil building steel structures, bridges, and large hoisting machinery. Background technique [0002] In steel structures or composite structures, the connections between steel members are generally welded, riveted or bolted. [0003] Although the welding connection has the advantages of simple structure, convenient manufacturing and processing, direct connection between weldments, no weakening of the cross-section and saving materials, the local material of the steel in the heat-affected zone of the weld becomes brittle, and the welding residual stress and residual deformation are reduced. The shortcomings of component bearing capacity and brittle fracture at low temperature are...
