Problems solved by technology

[0002] At present, the anchor bolts used in the curtain wall of the building envelope are affected by external forces such as hundreds of thousands of wind waves and thermal expansion and contraction every year, which will cause the anchors to loosen and the gap between the connecting holes to sag, resulting in accidents.
Therefore, in order to prevent the bolts from loosening and the gap between the connecting holes from sagging, the national regulations require that the screw, gasket, nut and the connecting anchor plate be welded to death. However, this welding on the construction site is not only difficult, but also exists Potential safety hazards of desoldering caused by welding on several different materials

Embodiment 1

[0038] Embodiment 1, with reference to attached figure 1 , 3 、5

[0039] An anti-displacement rivet bolt provided by the present invention comprises a metal rivet shank 1, the inner end of the metal rivet shank is provided with a protruding head 11, and the outer side of the metal rivet shank 1 has a breaking part 12 and there are tools and tools outside the breaking part. The connected connecting section 13; the rivet is also provided with a fastening sleeve 3, and the fastening sleeve 3 is correspondingly located on the outside of the connected part 100. The connected part 100 can be a plate, and the metal rivet Rod 1 has anti-loosening and riveting section 14 corresponding to said fastening sleeve 3, and anti-loosening and riveting section 14 is shaped on anti-stripping lines, such as concave lines, embossed lines, rings, annular grooves, etc., so that anti-loosening fastening Section 14 has an uneven surface. The inner hole of the fastening sleeve 3 is slightly larger tha...

Embodiment 2

[0057] Embodiment 2, with reference to figure 2 .

[0058] This embodiment is basically the same as Embodiment 1, except that the protruding rings 32, 111 of Embodiment 1 are changed to a plurality of protrusions 32, 111 arranged along the circumferential direction of this embodiment, and its shape can be point-like or block-like. , the effect of the projection 32 of the present embodiment is the same as that of the collar 32 of the embodiment 1, the effect of the projection 111 of the present embodiment is the same as that of the collar 111 of the embodiment 1, and the projections 32, 111 can be respectively There are tooth patterns matching the tooth pattern in the hole wall of the hole on the connected part for the metal rivet rod to pass through and the hole wall of the hole on the part that needs to be connected with the connected part for the metal rivet rod to pass through Teeth that match the inner teeth. figure 2 , unless otherwise stated, other and figure 1 The ...

Embodiment 3

[0059] Embodiment 3, with reference to image 3 , 4 .

[0060] In addition, this embodiment is basically the same as Embodiments 1 and 2, except that the collar or protrusion 32 is no longer provided, but the following structure is retained:

[0061] The front end surface of the fastening sleeve also has a concave-convex positioning configuration 33 that matches the outer surface of the connected piece. After the fastening sleeve is pressed by the tool to compress the connected piece, the concave-convex positioning The positioning configuration produces a non-slip fit between the outer surface of the connected part and the front end of the fastening sleeve to further prevent the loosening and displacement of the connected part. The concave-convex positioning configuration 33 can be concave-convex tooth pattern, mesh pattern, etc Anti-slip configuration; the hole through which the metal rivet rod passes through the connected part is a long hole or a round hole or a long groov...

Abstract

The invention provides a drifting-proof rivet bolt and a connecting structure of a building appendage. The rivet bolt is provided with a fixing sleeve and a metal rivet rod which is provided with a dropping-proof riveting segment corresponding to the fixing sleeve; under the action of a tool, the fixing sleeve is pressed against a connecting part, an inner hole of the fixing sleeve is tightened and wrapped outside the dropping-proof riveting segment, and a bumpy inner-hole surface matching with dropping-preventing lines on the surface of the dropping-proof riveting segment is formed simultaneously; permanent connection is formed and welding is omitted. A slide-proof positioning structure is arranged on the fixing sleeve and / or a raised-head side. According to the drifting-proof rivet bolt, permanent and firm connection and dropping prevention can be realized, connecting strength is improved greatly, the requirement on shock absorption is met, and labor force and cost can be saved. Drifting-preventing and positioning relationships between the fixing sleeve and the building appendage, and the metal rivet rod and parts connected with the connecting part are brought in, structure is simple, using effect is good, and strength and firmness of connecting and mounting can be improved greatly. The invention further provides a solution for fire proofing and heat resisting of the rivet bolt, and the drifting-proof rivet bolt is adaptable to various fire resisting areas.

Description

technical field [0001] The invention relates to an anti-displacement riveting bolt and a connecting structure, which is mainly suitable for riveting of various building curtain walls and various products with high requirements for anti-seismic and precision. It is especially suitable for the use of curtain walls of building envelopes with high requirements for anti-vibration, anti-slip, and anti-loosening. Background technique [0002] At present, the anchor bolts used in the curtain wall of the building envelope are affected by hundreds of thousands of wind waves and thermal expansion and contraction every year, which will cause the anchors to loosen and the gap between the connecting holes to sag, resulting in accidents. Therefore, in order to prevent the bolts from loosening and the gap between the connecting holes from sagging, the national regulations require that the screw, gasket, nut and the connecting anchor plate be welded to death. However, this welding on the con...
