Description

Fastening device for mounting highway guardrail

Technical Field

The utility model belongs to the technical field of guardrail installation, and particularly relates to a fastening device for installing a highway guardrail.

Background

The guardrail is widely applied to maintenance of municipal engineering, traffic, communities, ports, airports and storage areas, and the products are gradually developed and mature, become important branches of building material industry, and have continuously enlarged industry scale and continuously increased styles.

The guardrail mainly makes up into net type structure by horizontal pole and montant mutually perpendicular, it supports fixedly to have the stand to support it again, the horizontal pole uses the fastener overlap joint with montant interconnect is fixed more, peg graft and the welding punches a hole, because horizontal pole and montant material are thinner, inside is hollow, the bolt that present fastener overlap joint used is after the screw that inserts montant or horizontal pole, can lead to horizontal pole and montant screw surface atress damaged and tear the phenomenon, influence the stability and the life of guardrail.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to a fastening device for installing a road guardrail, which solves the above problems of the prior art.

In order to achieve the purpose, the utility model provides the following technical scheme:

the utility model provides a fastener is used in highway guardrail installation, includes fastener body, its characterized in that, the fastener body is provided with fastener A and fastener B including the symmetry, fastener A and fastener B horizontal direction all are equipped with the draw-in groove that encircles the contact with the horizontal pole, fastener A and fastener B are located the vertical direction of draw-in groove opening direction and all are equipped with the fastening splint that encircle the contact with the montant, fastening splint are screwed or are unscrewed through the fastening lantern ring that wraps up in the fastening splint surface, the horizontal cross section in all fastening splint's the outside is the arc, and the arc center of every fastening splint all is in on same centre of circle point.

Preferably, a protrusion is arranged in the horizontal direction of the middle position of the upper edge of the clamping groove of the fastener A, a groove is arranged in the horizontal direction of the middle position of the upper edge of the clamping groove of the fastener B, and the protrusion is engaged with the groove in a matching manner.

Preferably, the two opposite sides of the fastener A and the fastener B are provided with mounting holes, and the mounting holes can be used for inserting bolts for fixing.

Preferably, a limiting ring with internal threads is arranged at a distance of 1-3cm from the outer wall of the fastening splint in a surrounding mode, and the inner diameter of the limiting ring is the same as the outer diameter of the fastening lantern ring.

Compared with the prior art, the utility model has the beneficial effects that:

the two fasteners are matched and fastened on the cross rods, the cross rods play a main supporting role, the fastening clamping plate is fastened at one end of the vertical rod at the moment, the vertical rod cannot vertically displace between the two cross rods, the vertical rod is effectively limited by the fastening clamping plate at the moment, and the fixing purpose is further realized on the vertical rod.

Detailed Description

Referring to fig. 1 to 5, in an embodiment of the present invention, a fastening device for installing a road guardrail includes a fastening member a101 and a fastening member B102 having a structure with a vertical cross section of Contraband font, the fastening member a101 and the fastening member B102 are respectively and symmetrically sleeved on two sides of a cross bar 8, and simultaneously, inner sides of four fixing clamp plates 4 located below the fastening member a101 and the fastening member B102 are respectively and uniformly attached around an outer wall of a vertical bar 9, so as to enhance the stability of the fixing clamp plates 4 clamping the guardrail vertical bar 9, a fastening ring 7 is utilized to slide upwards along the vertical bar 9 and is in threaded connection with the outer wall of the fastening clamp plate 4, since the fastening ring 7 is in a closed loop structure, the fixing clamp plate 4 is retracted inwards and extrudes the vertical bar 9, and at this time, the friction force between the fixing clamp plate and the vertical bar is enhanced by structural limitation.

To increase the sealing ability of the fasteners when they are closed, as shown, the protrusions 5 on fastener A101 and the recesses 6 on fastener B102 are mortise and tenon connected when the two fasteners are in contact with each other.

To avoid the fasteners sliding or rotating on the cross bar 8, the two fasteners are fastened to each other by passing the bolts through the two mounting holes 2 and through the cross bar in the cavity of the cross bar 8, and then securing the free ends of the bolts with nuts, as shown in fig. 1.

In order to avoid a gap between the fastening piece and the fastening collar 7, the fixing splint 4 between the fastening piece and the fastening collar 7 is exposed, as shown in fig. 3 and 4, the height of the stop collar 3 is one third of the height of the fastening collar 7, and after the fastening collar 7 is screwed and the socket is stabilized, the top end part of the fastening collar 7 enters the inner side of the stop collar 3.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the scope of the present invention, and the technical solutions and the utility model concepts of the present invention are equivalent to or changed within the scope of the present invention.
