Problems solved by technology

However, due to the increase of the contact area between the bolt and the keel, the heat conduction area of ​​this structure also increases correspondingly, which cannot achieve good heat insulation and fire protection performance.
Moreover, when installing this kind of fastener, it is necessary to slide the buckle joint from the end of the keel into the inner expansion groove. When the length of the keel is long, it will bring great inconvenience to the installation. In addition, the fastener can be expanded internally. Sliding in the groove means that there must be a certain gap between it and the side wall of the inner expansion groove, that is, the fastener can rotate, which is likely to cause connection failure

Embodiment 1

[0027] Such as figure 1 and figure 2 As shown, the present invention is used for the first embodiment of the connector of the inner expansion groove pipe. The positive notch of the expansion groove 41 extends into the inner expansion groove 41, one end of the pull rod 1 is connected with the fastener 2, and the other end is connected with the locking member 3, and the pull rod 1 drives the fastener 2 to rotate the angle and then the inner expansion groove 41 pairs The fastener 2 forms a vertical limit, and the pull rod 1 is equipped with an anti-rotation shrapnel 7 that elastically deforms when it is pressed down and rotates, and snaps back into the positive notch of the inner expansion groove 41 after rotation. When the locking member 3 is locked, the pull rod 1 drives the fastener 2 to fasten with the inner expansion groove 41. This connector is used in the curtain wall system. When installing, first connect the tie rod 1 with the fastener 2, and then extend the fastener ...

Embodiment 2

[0036] Such as image 3 and Figure 4 As shown, the second embodiment of the connector of the present invention for the inner expansion groove pipe, the connector is basically the same as the embodiment 1, the only difference is: in this embodiment, the anti-rotation shrapnel 7 is set on the pull rod 1 And do not rotate with pull rod 1. In this structure, the anti-rotation shrapnel 7 can only be pressed by the pull rod 1 but not by the rotational torque of the pull rod 1, and can also achieve the effect of being deformed by the pull rod 1 and rebounding to drive the back buckle.

[0037] In this embodiment, the anti-rotation shrapnel 7 is provided with a fitting hole 71 , and the tie rod 1 is provided with a pressing table 12 , the anti-rotation shrapnel 7 is set on the tie rod 1 and the pressing table 12 is pressed against the edge of the fitting hole 71 . In this structure, when the pull rod 1 is pressed down, its pressing platform 12 presses against the edge of the set ho...

Abstract

The invention discloses a connecting member for an internally expanded groove tube. The connecting member comprises a pull rod, a fastener and a locking part, wherein the fastener extends from a frontgroove opening of an internally expanded groove of the internally expanded groove to the internally expanded groove, one end of the pull rod is connected with the fastener, the other end of the pullrod is connected with the locking part, the internally expanded groove vertically limits the fastener after the pull rod drives the fastener to turn at an angle, the pull rod is provided with a rotation-preventing spring piece producing elastic deformation during down-pressing rotation and then rebounding to be fastened into the front groove opening of the internally expanded groove after rotation, and the pull rod drives the fastener to be fastened with the internally expanded groove when the locking part is locked. The connecting member has the advantages of being simple and ingenious in structure, convenient to install and capable of achieving positioning and rotation prevention.

Description

technical field [0001] The invention mainly relates to the field of construction engineering, in particular to a connecting piece for an internally expanded grooved pipe. Background technique [0002] At present, the glass curtain wall is popularly used on the building surface. The curtain wall includes keels, curtain wall panels, pressure plates and bolts. The curtain wall panels are carried on the keels, and the pressure plates are pressed on the curtain wall panels. The pressure plates are connected to the keel through bolts. platen. In this kind of curtain wall structure, the bolts are directly threaded on the keel, which is equivalent to the threaded connection of the bolts directly with the bearing surface of the keel, that is to say, the locking force is concentrated at the threaded connection position to form a point force, on the one hand, it is easy to cause stress concentration and damage keel; on the other hand, bolts are also prone to fracture and failure due t...
