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 wind waves and thermal expansion and contraction hundreds of thousands of times a 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

[0035] Embodiment 1, with reference to attached figure 1

[0036] An anti-displacement blind rivet bolt provided by the present invention includes a metal rivet rod 1, an anti-lock expansion part 2, and a casing 4. The inner end of the metal rivet rod is provided with a protruding head 11 that expands the anti-lock expansion part 2, and the metal rivet rod The outer side of 1 has a connecting section 13 for connecting with tools, and the metal rivet rod 1 passes through the anti-lock expansion part 2; the blind rivet bolt is also provided with a fastening sleeve 3, and the fastening sleeve 3 is correspondingly located On the outside of the connecting piece 100, the connected piece can be a plate, and the metal rivet rod 1 has an anti-loose riveting segment 14 corresponding to the fastening sleeve 3, and the anti-loosening riveting segment 14 is formed with an anti-loosening Lines, such as concave lines, embossed lines, rings, annular grooves, etc., make the surface of the...

Embodiment 2

[0042] Embodiment 2, with reference to attached figure 2 .

[0043] In addition to the embodiment of the embodiment 1, the anti-lock expansion member 2 can also be a single ring-shaped element like this embodiment, and the plurality of expansion pieces are arranged along the circumferential direction of the ring. The sleeve 4 is integrated with the fastening sleeve 3 .

[0044] Further, the front end of the tightening sleeve has a bead or protrusion 32, and the bead or protrusion 32 is used to squeeze the connected part tightly when the tightening sleeve 3 is pressed by the tool. , is squeezed into the gap between the hole wall of the hole through which the sleeve 4 passes through the connected piece and the sleeve 4, forming a squeeze or interference fit, and plays a positioning role for the connected piece to prevent slippage, further Keep it from sagging or loose up and down.

[0045] The collar or protrusion at the front end of the fastening sleeve can also have tooth ...

Embodiment 3

[0047] Embodiment 3, with reference to image 3 .

[0048] In this embodiment, the implementation of the anti-locking expansion member 2 , the sleeve 4 and the fastening sleeve 3 will be described emphatically.

[0049] In this embodiment, the relationship among the anti-lock expansion member 2 , the sleeve 4 and the fastening sleeve 3 adopts the method of the first embodiment. In addition, there is a protruding ring 32 at the front end of the tightening sleeve 3, and the protruding ring or protrusion 32 is used for being pressed when the tightening sleeve 3 is pressed tightly by the tool to tighten the connected part. Squeeze into the gap between the hole wall of the hole through which the sleeve 4 passes through the connected part and the sleeve 4 to form a squeeze or interference fit, and play a positioning role to prevent slipping of the connected part, further preventing its Saggy or loose up and down.

Abstract

The invention provides a drifting-proof blind rivet bolt and a connecting structure of a building appendage. The blind rivet bolt is provided with a fixing sleeve, and a metal rivet rod of the blind rivet bolt 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. According to the drifting-proof blind 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 relationship between the fixing sleeve and the building appendage is brought in, structure is simple, and using effect is good. The invention further provides a solution for fire proofing and heat resisting of the drifting-proof blind rivet bolt, and the drifting-proof blind rivet bolt is adaptable to various fire resisting areas.

Description

technical field [0001] The invention relates to an anti-displacement blind rivet bolt and a connection structure using the blind rivet bolt, which is mainly suitable for the riveting of hollow columns of various building curtain walls and various products with high requirements for earthquake resistance 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 external forces such as wind waves and thermal expansion and contraction hundreds of thousands of times a year, which will cause the anchors to loosen and the gap between the connecting holes to sag, causing 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 an...
