Abstract
A post having particular utility for use in a highway sound barrier wherein a number of posts are set along the highway to support acoustical panels. Each post is made of reinforced precast concrete having side channels to mount the acoustical panels. The posts are supported on poured concrete footings having a tapered depression in the top surface which is reinforced by a surrounding array of closed loop reinforcing rods. The post is inserted in the depression and bonded thereto by a quick setting grout.
Claims13
A fence post combination comprising an elongated, vertical, cylindrical, concrete footing embedded in the ground with a top exposed portion having a flat top, a depression located in a central portion of said flat top, said depression having a base and a plurality of side walls forming an opening in the flat top, a plurality of vertical reinforcing rods embedded in said concrete footing and extending substantially the entire length thereof, said vertical reinforcing rods being arrayed around said depression, a plurality of reinforcing rings embedded in said concrete footing and surrounding said depression, said reinforcing rings and reinforcing rods serving to strengthen said concrete footing surrounding said depression, a precast concrete post vertically mounted in said depression with the bottom of the post seated on the base of the depression, and a quantity of quick setting, high strength grout filling a space in the depression surrounding the post to bond the post to the footing.
A method of making a post for a sound barrier fence, said method comprising the steps of:
- (a) boring a hole in the ground for a footing;
- (b) placing a concrete reinforcing assembly in said hole comprising an array of vertical reinforcing rods extending from the bottom of the hole to the top, and a stacked array of closed loop reinforcing rods horizontally disposed at an upper location of the vertical rods;
- (c) placing an open topped form with tapered side walls and a flat base centrally within the array of closed loop reinforcing rods with the array extending from the top of the form to the bottom;
- (d) pouring concrete into said hole, filling said hole and covering said reinforcing assembly to a level of the open top of said form;
- (e) removing said open topped form prior to the concrete completely curing, leaving a depression in the top of the footing with an open top, tapered side walls and flat base of a configuration matching the external shape of said open topped form;
- (f) vertically mounting a precast concrete post with a flat bottom and opposed sides in said depression with the base of the post resting on the base of the depression, the post being formed with opposed channels on opposite sides of the post;
- and
- (g) filling the space between the post and side walls of the depression with a high strength, quick setting grout to bond the post to the footing.
