Fatigue-resistant long-acting back rivet bolt and curtain wallboard connecting structure

Abstract

The invention provides a fatigue-resistant long-acting back rivet bolt and curtain wallboard connecting structure. The fatigue-resistant long-acting back rivet bolt and curtain wallboard connecting structure is characterized in that a back rivet bolt comprises a metal rivet rod, a sleeve and a fastening sleeve, the metal rivet rod is provided with an anti-loose riveting section, the fastening sleeve compresses a connected member under the action of a tool, an inner hole of the fastening sleeve is contracted and wraps the outside of the anti-loose riveting section, and concave-convex inner hole surfaces matched with anti-dropping grains on the surface of the anti-loose riveting section are simultaneously formed, so that the connected member can be permanently connected with the back rivet bolt without welding; the sleeve is a plastic member. The fatigue-resistant long-acting back rivet bolt and curtain wallboard connecting structure has the advantages that the back rivet bolt can be permanently and firmly connected with the connected member in an anti-loose manner without welding, the connection strength is greatly improved, seismic requirements can be met, and labor and the cost can be saved; flexible blades and an expansion component can be positioned, so that the flexible blades are assuredly constantly padded on expansion elements, existing configured flexible sleeve components for fasteners can be omitted while a flexible anti-seismic effect can be assuredly and reliably realized, and the requirement on applying the fatigue-resistant long-acting back rivet bolt and curtain wallboard connecting structure to dry-hanging curtain walls of external building envelop structures, braking-impact-resistant subway stations and the like with high seismic requirements can be met completely.

Description

technical field [0001] The invention relates to a connection structure between fatigue-resistant and long-lasting back riveting bolts and curtain wall panels, which is mainly suitable for the decoration of dry-hanging panels in various buildings, and is connected to the back of the panels, so it is called "back riveting bolts" and is more suitable for anti-vibration It can be used for dry-hanging curtain walls such as building envelope structures and anti-braking shock subway stations and other dry-hanging curtain walls with high life expectancy requirements. Background technique [0002] At present, the back bolts used in the curtain wall of the building envelope are connected by bolts and screws. Due to the influence of hundreds of thousands of wind waves every year and external forces such as thermal expansion and contraction, the anchors will loosen; moreover, due to the current In order to prevent the screw rods from rotating, the back bolts of the screw rods are provid...

AI Technical Summary

Problems solved by technology

But as a back bolt with a diameter of only 6MM, it is difficult to complete the welding, especially when there is a plastic flexible sleeve in the back bolt to increase the shock resistance, the high heat of welding will be applied to the plastic along the metal parts of the back bolt due to the heat conduction of the metal In addition, during construction, the expansion part of the expansion ring (sheet) is difficult to align with the plastic flexible sleeve, resulting in that after installation, the expansion part of the expansion ring (sheet) is not covered by the flexible sleeve. Pad by flexible blades, resulting in the hidden danger of uneven bearing

[0003] In addition, as far as the above structure is concerned, when the nut is tightened, the overall rotation of the anchor bolt will also be caused.

Moreover, in screw manufacturing, due to the reason of the anti-slip boss, the mold of the heading machine often cracks, and the manufacturing cost increases
