Embodiment 1

[0017] Such as figure 1 , figure 2 As shown, a self-tensioning tie rod connection structure includes a tie rod 6 with ball ends 3 at both ends, and connecting posts 5 are respectively arranged on the ball ends 3 of the tie rods 6; the outer ends of the connecting posts 5 have internal threads 2. The inner end has a spherical groove 4, and the ball end 3 of the tie rod 6 is matched with the spherical groove 4 of the connecting column 5; the tie rods 6 inside the two connecting columns 5 are respectively provided with dead end pads 7, The dead head block 7 is fixed on the pull rod 6 through a top screw 8, and the top screw 8 plays a position-limiting role. All components of the present invention are made of stainless steel.

[0018] During the connection process, the internal thread 2 of the connecting column 5 of the present invention is connected with the stud 1 with external thread; this structure can resist component deformation caused by temperature expansion and contrac...

Embodiment 2

[0021] Such as image 3 , Figure 4 As shown, a self-tensioning tie rod connection structure includes a pull rod 6, a pendulum rod 14, a movable head block 10, a dead end block 7 and a connecting column 5, and one end of the pull rod 6 is a rod end with an external thread, and the other One end is a ball end, and one end of the pendulum rod 14 is a rod end with external threads, and the other end is a ball end, and the pendulum rod 14 plays the role of connecting the first connecting column 11 and the movable head block 10; The ball end 12 of the stick is provided with a first connecting post 11, the outer end of the first connecting post 11 has an internal thread 2, and the inner end has a spherical groove 4, and the ball end 12 of the pendulum stick is connected to the first connecting post 11. The spherical groove 4 matches; the rod end 15 of the pull rod and the rod end 13 of the pendulum rod are all arranged in the internally threaded hole of the movable head pad 10, and...

Abstract

The invention relates to an external maintenance structure for builds, in particular to a connecting structure for a self-tension pull bar which is a pre-tension rod piece applied to a curtain wall structure and capable of achieving self-tension. The connecting structure comprises a pull rod provided with ball ends at the two ends, wherein connecting pillars are respectively arranged at the ball ends of the pull rod; each connecting pillar is provided with an internal thread at the outer end and a spherical surface groove at the inner end; the ball ends of the pull rod are matched with the spherical surface grooves of the connecting pillar; and dead-head cushion blocks are respectively arranged on the inner sides of the two connecting pillars of the pull rod, and fixed on the pull rod through top wires.

Description

technical field [0001] The invention relates to a maintenance structure outside a building, in particular to a self-tensioning rod connection structure, which is a pre-tensioning rod applied to a curtain wall structure. Background technique [0002] The supporting steel structure of the curtain wall is various and ever-changing. Due to the force requirements, some special projects need to use prestressed rods to support the curtain wall frame. Traditional prestressed tie rods have a wide range of applications, but the method of applying pretightening force is very single. Basically, equipment such as jacks is used to tension the rods, and the on-site operation is cumbersome; and due to the limitation of construction space, some large and medium-sized equipment cannot be installed Field Application. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a self-tensioning rod connection structure capable of reali...
