Embodiment 1

[0022] see Figure 1~3 , in an embodiment of the present invention, an inner sleeve-type column connection node based on civil engineering, including a cylinder body 1, an upper connection chamber 2 arranged on the upper part of the cylinder body 1, a lower connection chamber 3 arranged on the lower part of the cylinder body 1, For the fixing assembly installed in the lower connection chamber 3, it should be noted that there is no communication between the upper connection chamber 2 and the lower connection chamber 3, and there is a partition between them;

[0023] Specifically, the fixing assembly includes an elastic plate 4 sleeved inside the lower connecting cavity 3, bosses 5 fixed on both sides of the elastic plate 4, telescopic rods 7 at the ends of the hinged bosses 5, sleeved on the telescopic rods 7 The swing rod 8 at the bottom, and the clamping mechanism connected to the lower end of the swing rod 8, wherein, both sides of the outer wall of the lower connection cavi...

Embodiment 2

[0027] In order to facilitate the ejection of the rods connected to the upper connection cavity 2 and the lower connection cavity 3 after the pin 14 is removed, and to speed up the disassembly, in another embodiment of the present invention, an inner sleeve type column connection based on civil engineering Node, the partition between the upper connection chamber 2 and the lower connection chamber 3 is fixed with a bullet-feeding assembly, and the bullet-feeding assembly includes a fixed sleeve 17 fixed on the partition, a spring 18 seated inside the fixed sleeve 17, The extruding rod 16 sleeved at both ends of the fixing sleeve 17, wherein the end of the extruding rod 16 is fixed with a push plate 15, one end of the spring 18 abuts against the lower end of the upper extruding rod 16, and the other end of the spring 18 abuts against the lower end of the extruding rod 16. The upper end of the pressing rod 16;

[0028] Still further, there is a flange at the joint between the ext...

Abstract

The invention discloses an inner sleeve-type column connection node based on civil engineering, in particular, a telescoping rod is pulled out from a swing rod by squeezing an elastic plate after the lower connecting rod is assembled and drives the swing rod to swing, and the swing rod pushes the The roller and the clamping rod drive the friction ring to encircle and hug the rods sitting in the lower connection cavity in the circumferential direction under the action of the sleeve, which effectively solves the problem that the existing inner sleeve type column connection structure cannot be adjusted according to different diameters. The rod is tightly held, and it is easy to shake. The fixed assembly includes an elastic plate set inside the lower connection cavity, bosses fixed on both sides of the elastic plate, a telescopic rod at the end of the hinged boss, a swing rod set at the lower part of the telescopic rod, and a tight grip connected to the lower end of the swing rod. The mechanism, wherein, both sides of the outer wall of the lower connection cavity are fixed with fixed columns hinged with the middle of the swing rod, and both sides of the cylinder are provided with guide grooves for the boss to pass through.

Description

technical field [0001] The invention relates to a construction tool, in particular to an inner sleeve type column connection node based on civil engineering. Background technique [0002] At present, the joint connection types between concrete columns mainly include sleeve connection and slurry anchor connection. It is suitable for the connection between large diameter steel bars. It has the characteristics of energy saving and not being restricted by the composition and type of steel bars. [0003] At present, the existing sleeve connection tools generally have tapered thread connection joints, which are connected by joints formed by the special tapered thread at the end of the steel bar and the tapered thread of the connector; straight thread connection joints, the quality of the joint is stable and reliable, and the connection strength is high. It can be compared with the sleeve kneading joint, and has the characteristics of convenient construction and fast speed of the...
