## Title
Fence construction system for building a fence with a wall appearance and characteristics and method for building such a fence

## Abstract

A fence construction system and a method for building such a fence are provided. The fence looks like a wall and has wall characteristics, such as a post-tension condition, but is much less expensive and easier to build. A ratcheting system or tensioning system is used to tension the tensile wires which are then secured to the fence posts. A wire lath is applied to the tensile wires and coating material is then applied to the surface of the wire lath. After forming the fence construction, the tensile wires are released and the ratcheting posts are removed. The fence construction system can be used to build a fence portion of up to 300 feet long at one time.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a fence construction system for building a fence and a method for building a fence. More particularly, the invention relates to a fence construction system for building a fence that looks like a wall and a method of using such a fence construction system to build the fence. The fence construction system and method of the present invention are very easy to use and can build fences inexpensively with an elegant wall appearance and additional security.
It is common practice for a homeowner or a land developer to build a fence around his or her property to separate the property from neighbor's properties and provide the house with a certain extent of privacy and security. However, a regular fence often cannot prevent the passersby from looking through the fence and cannot provide satisfactory appearance and security. In order to protect privacy, to provide higher security and to improve the appearance of the house, some homeowners and land developers choose to build a wall.
However, it is very expensive and time consuming to build a wall. Therefore, not everybody can afford to build a wall. The people who cannot afford a wall and who are not satisfied with a regular fence do not have any other choice.
Therefore, there is a need for a new fence construction system and a method for building such a fence that has a wall appearance and characteristics but is much less expensive and easier to build.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention may be understood more readily by reference to the following detailed description of preferred embodiments of the invention.
Before the present invention is disclosed and described, it is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. It must be noted that, as used in the specification and the appended claims, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise.
The present invention will now be described in detail with reference to the accompanying drawings.
Referring to the drawings and initially to FIG. 1, there is diagrammatically shown a representative fence construction system generally designated by the reference numeral 10. Before beginning the construction of the fence, a survey must be conducted to decide the size, the height and the configuration of the fence, according to which the fence layout and post locations are then decided and marked. Post holes (shown in FIGS. 5-6) are then dug at the post locations. The post holes can be of any size big enough for the fence posts, but are preferably to be about 8 inches×10 inches in diameter and about 24 inches in depth. Fence posts 20 are then placed into the post holes. The number and the size of the fence posts and the distance between the fence posts are determined by the dimensions and configuration of the fence. The fence posts are then plumbed, aligned to the layout of the fence and secured with concrete, e.g., 2500 psi concrete, in the post holes. As is shown in FIGS. 5 and 6, depending on the soil, the post holes can be deeper than the embedment of the fence posts to avoid the contact of the bottom of the fence posts with the soil. This can be done by pulling the fence posts a distance upwards before the concrete sets.
Next, two temporary ratcheting posts (or tensioning posts) 30 are installed beyond two end fence posts. One of the ratcheting posts has a plurality of holes 32 on two opposite side faces (only one side is shown) of the ratcheting post. The holes are used as fastening locations for the assembly of ratchets or tensioners 34. The number of ratchets or tensioners 34 depends on the number of high-tension tensile wires to be used, which in turn depends on the customers' requirement and the local government regulations. A plurality of high-tension tensile wires 40 are strung between the two ratcheting posts 30 at one side or both sides of the fence posts 20. One end of each wire is fixed to one ratcheting post and the other end is attached to a ratchet on the other ratcheting post. The high-tension tensile wires 40 are about 12-18 gauge and spaced about 8-12 inches apart vertically.
The high-tension tensile wires 40 (e.g. A102 Superlife 12 HT wire) are tensioned by turning the ratchets 34 (e.g. distributed by MAX-FLEX company) clockwise to a torque of about 150-250 LBS per square inch and then are secured to the fence posts 20 by staples, clips or any other fasteners. As is shown in FIG. 2, after applying the tension to the high-tension tensile wires 40, the ratcheting posts 30 might incline towards each other. In order to secure the ratcheting posts 30 during the construction, additional supporting posts 50 can be used.
As is shown in FIGS. 1, 3 and 4, wire lath(s) 60 can be secured to one or both opposite sides of the fence posts 20 and to the tensioned tensile wires 40 by clips or any other fasteners 62 (e.g. A300 Spring clip tighteners). The wire laths can be galvanized metal or plastic and are about 2.8-3.4 gauge. Fence coating material 70 is then applied to the surface of the wire lath. The WONDERTECTM coating material produced by Wondertec of America, Inc. is especially suitable for building the fence construction according to the present invention. Alternatively, other coating material (such as ASTM A 854-94 with a minimum strength requirement of 1800 PSI) can also be used. Typically, the coating material 70 includes three coating layers 72, 74 and 76 (see FIG. 1). First, a scratch coat 72 (e.g. Portland cement mixture with polymers, various fiber particles and selected sizes of aggregate) is applied with potable water to the wire lath. Then a brown coat 74 of the same mixture is applied to the surface of the scratch coat. At last a finish coat 76 (e.g. texture coat of choice) is applied to the surface of the brown coat. The thickness of the scratch coat layer and the brown coat layer are about 3⁄8 inch.
As shown in FIG. 1B, after the forming of the coating, the tensioned high-tension tensile wires 40 are cut outside the end fence posts to create a post-tension condition in the fence construction. The temporary ratcheting posts 30 are then removed and the end fence posts are touched up at where the high-tension tensile wires were cut. The thus-formed fence construction can then be painted with a prime coat or a color coat according to choice.
To further improve the appearance of the fence, wire lath and coating can also be applied on the top surface of the fence (as shown in FIGS. 5 and 6). Pre-constructed non-structural columns 80 (as shown in FIG. 3), which are made of wooden vertical posts in the corners, horizontal spaces therebetween and wire lath and stucco, can be used to provide decoration at the corners or gate of the fence. As shown in FIGS. 5 and 6, the bottom of the fence is unsupported by the ground.
The fence construction system according to the present invention can be used to build a fence portion of up to 300 feet long at one time.
Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. It is intended that the specification and examples be considered as exemplary only.
