초록 ▼

A texturing broom apparatus for surface grooving freshly laid uncured concrete pavement comprising a traveling horizontal endless conveyor belt having a texturing broom, provided with a row of straight spring steel tines projecting from a base board in spaced apart side-by-side parallel relation, pivotally mounted on the conveyor belt for pivotal movement thereon in a vertical plane parallel to the direction of belt travel with the row of tines extending transversely across and outwardly from the belt and the tines disposed parallel to the longitudinal vertical plane of the belt. Spring means biases the pivoted broom forwardly of the direction of belt travel to a limiting idle position and the broom is supported on the belt in a position with its tines in a trailing working position disposed above and at a shallow working angle of less than about 20°to the pavement surface, during the travel of the broom along the lower run of the belt, and with the free ends of the tines spring-pressed into engagement with the surface of the uncured pavement to form the texturing grooves therein during the traverse of the broom thereacross. The tines of the texturing broom are clamped at one end to the broom base board by a metal strap extending transversely across the tine ends and secured to the base board by fastening screws on each side of each of the tines, and the spaces between the metal strap and base board at the gaps between the adjacent tines are filled with an epoxy adhesive.

In apparatus for forming shallow texturing grooves in the surface of freshly laid uncured concrete pavement confined within side form members, said apparatus including a horizontally extending endless conveyor belt movable to carry a texturing broom mounted thereon across the pavement surface to be textured to form the said grooves therein, said broom includng a header board having a row of straight spring steel tines projecting equidistantly therefrom in spaced apart side-by-side parallel relation and disposed in a common plane, the improvement comprising: mounting means including hinge means supporting said broom on said belt for pivotal movement thereon about a horizontal axis normal to the direction of travel of the belt with the said row of tines disposed transversely across the belt and the tines extending from said header board in a direction outwardly of the belt and parallel to the longitudinal vertical plane thereof; spring means biasing said pivoted broom forwardly of the direction of travel of said belt; and adjustment means on said mounting means engageable with said broom to set it in a predetermined limiting pivoted idle position on said belt with the said tines extending in a direction generally perpendicularly outward of said belt; said mounting means supporting said broom in a predetermined position on said belt relative to the surface of said pavement to engage with and be pivoted rearwardly upward, by the one of said form members at the leading end of the pavement to be traversed by the broom during its travel along the lower horizontal run of said belt, from its said pivoted idle position to an operative working position with the said tines trailing and disposed at a shallow working angle relative to the pavement surface for spring pressed engagement of the free ends of the said tines with the pavement surface to form the said grooves therein.
