TITLE: A CORNER PROTECTIVE MEANS FOR WALLS, BEAMS COLUMNS ETC
ABSTRACT OF THE DISCLOSURE
A corner protective means for walls, beams, columns, etc. which
has adequately formed bevel angles, rib strips, and bent tails on
its two wings so that more powerful grip strength may be provided
by it when it is burried into a cement roughcast before the
cement is dried. With this corner protective means, a faster and
easier installation is available while smoother surface finish of
wall corner may be achieved easily.

Revendications

I claim:
1. A corner protective means for walls, beams, columns etc
comprising a sectorial front and two integrally formed
wings; said wings extending outward from kwo edges of said
sectorial front whlle they first bend inward at said edges
of said sectorial fronk then bend outward to form an angle
about 30-40 degrees thereat permitting the wings to extend
in a direction substantially parallel to but slightly
inclined to a wall surface over which said corner
protective means is installed: said wings also having a
plurality of rib strips, formed on their both sides and an
inward bent tail formed at their free ends each.

Background of the Invention
_________________________._
In common construction of civil engineering, a lot of time is
wasted in stuccoing and strengthening projected corners of walls,
beams, columns, etc. Due to lack of proper corner protective
means, defects such as insufficient strength of corner, inferior
appearance, etc. also exists when the construction is
completed. Although there are other commercially available
simple corner protective means, most of them are inconvenient in
installation, inferior quality, low performance, and becoming
loose easily.
Therefore, it is tried by the applicant to develop a corner
protective means for walls, beams, columns, etc. Which may
eliminate the drawbacks existing in the prior art.
Summary of Invention
___.________________
It is a primary object of the present invention to provlde a
corner protective means which has a generally sec'corial front and
two wings extending outward from two edges of the sectorial front
to form a generally right angle, and may be insert into the

concrete before final finish of walls, beams, columns etc., so
that it may firmly grip the concrete structure with many rihs,
bent tails, and bevel angles formed on its two wings.
The structure, functions, and other advantages o~ the present
invention may be readily understood by referring to the following
description and accompanying drawings in which:-
BRIEF DESCRIPTION OF THE DRAWLNGS

invention; and
Fig.2 illustrates a corner protective means of
the invention having been installed to
join with the concrete wall corner.
DETAILED DESCRIPTION OF PR~FERRED EMBODIMENT
____________________~__________________ ____
Please refer to~Fig.1. The corner protective means 1 of the
invention generally has a sectorial front and two wings 10
extending outward from two edges of the sectorial front. The
wings 10 are generally symmetrically formed, so, description of
one wing shall represent two wings in the specification. The
;

wing 10 firstly bends inward at an edge of the sectorial front,
then bends outward to form an angle about 30 or 40 degrees so
that the whole sectorial portion of the corner protective means 1
looks like a dove tail~ Furthermore, on both sides of the wing
10, a plurality of rib strips 11 are formed to increase the
contact area of the wing 10 with concrete structure and thereby
strengthens the holding of wing 10 by the concrete~
A bent tail 13 is formed at the open end of the wing 10 to
reinforce the grip capability of the wing 10. Please further
refer to Fig.2, in which a corner protective means of the present
invention having been installed and insert on a wall corner is
illustrated. From this figure, a powerful joining strength
provided by dovetail-shaped structure, xib strips 11, and bent
tails 13 of the corner protective means 1 can be fully
undsrstood.
During construction, please refer to Fig.2 concrete walls,
beams, columns, and their projected corners 14 formed by grouting
usually have a surface which needs a first time cement coating to
form a layer of roughcast 15. During the process of coating this
roughc~st 15, the corner protective means 1 of the invention is
positioned over the projected corner 14 in a manner that the
wings 10 are burried into the roughcast 15 before the same is
dried. ~hen the roughcast 15 is dried~ the the corner protective
means 1 shall be firmly inserted thereon. ~hen, a fine finish 16
'.' '' ~

formed by a second time cement coating shall provide a smooth
wall surface which is flush with the e~ges of the sectorial front
of the Corner protective means 1.
It is to`be understood that the form of the invention shown and
disclosed is to be taken as a preferred embodiment of the
invention and that various changes in the shape, size and
arrangement of parts may be resorted to without departirlg from
the spirit of the invention or the scope of the following
claims.
