Telescopic Post and Bracing System for Bedrock Locations

Abstract

A post assembly for fencing comprises a telescopic post (11, 12) on a ground anchor plate (10) and a telescopic bracing stay.

Description

FIELD OF THE INVENTION[0001]The present invention relates to the installation of posts in general, being for fences, stockyards or any other construction where a post may be anchored directly to bedrock.BACKGROUND ART[0002]Fence and stockyard posts are well known in their general form. One such application is that the post is placed in a hole and backfilled with concrete or soil.[0003]When bedrock is found under the location of a post, the rock is either blasted with explosives or jackhammered out to allow the location of the post. The post is then placed in the hole and the hole is filled with concrete poured around the base of the post to fix the post in place.[0004]Similarly, posts may be bolted to a concrete retaining wall or concrete pods that are poured in the post's location.[0005]Prior art fence post assemblies include one arrangement described in U.S. Pat. No. 5,649,690 which discloses a portable fence post support system having a box-shaped base member with a support face ...

AI Technical Summary

Benefits of technology

[0010]The present invention is directed to a post or column used to anchor any structure to rock, which may at least partially overcome at least one of the abovementioned disadvantages or provide the consumer with a useful or commercial choice.

[0020]The ground anchor plate will typically be provided with a first post attachment portion in order to attach the first post portion. For example, an open portion may be provided to receive the first post portion, said open portion being a depression or slot recessed into or extending through the plate (which would require a hole to be formed in the underlying ground or rock, but which would greatly add to stability).

[0033]Cover means or grommets may be placed to cover any unused openings in the first or second post portion to decrease and preferably prevent, the ingress of foreign matter such as dust or dirt which may damage the post.

[0042]For the hinged post, a bracing ring may be slipped over the top of the post and bolted preferably ⅓ down from the top of the post. The bracing ring may be of circular appearance with each end of the ring provided with a flange bent at approximately 90° outwards. The bent flanges may have holes drilled in them to accommodate bolts, so that the bracing ring may be fastened to the post. Several pieces of preferable flat steel may be welded to the bracing ring, with one or more holes in them. This bracing ring will allow the bracing stay to be bolted to the post.

Problems solved by technology

Accordingly, either the post must be driven deeply into the ground or relatively deep holes for receiving the post therein must be dug, both of which are relatively laborious.

Yet posts placed directly into the earth are difficult to remove.

However, anchoring devices still often require the excavation of a hole for receiving the device.

Additionally, the design of traditional fence post systems limit installation to either rocky or fine soils.

A separate anchoring device is often necessary for securing the brace to the ground, which of course further complicates installation and removal.”

Whilst each of the above described systems and devices are useful in their own manner, none address
