BR202013011888U2 - JOINT PIECE FOR CAIBROS - Google Patents

Abstract

SUMMARY CABLE JOINT PART, comprising a rectangular plate (1), where four cuts (2) have been made by removing the corners, giving rise to ears which are folded in opposite directions to form an upper U-socket (3) ) and a lower U-socket (4), offset by 90 degrees from one another; such that a rafter (5) may be seated in the upper housing (3) and a ridge (6) in the lower housing (4).

Description

FIELD JOINT PART TECHNICAL FIELD

The following descriptive report for utility model refers to the development of a rafter joint where said part is in the form of an inverted double "U" whose purpose is to facilitate the assembly of shapes

for concrete, eliminating the use of nails for fixing the main rafters to the secondary rafters. STATE OF ART

Various pieces and devices for joining concrete forms are known in the prior art.

ANDRADE (2009) Pl 0.901.188-9 describes a formwork joining device for concrete with suitable locations for the use of quick couplings (or use of screws) and concrete form spacers where the device provides the fastest speed. assembly and disassembly, connection and spacing and, above all, those angled joints

(as in two walls perpendicular to each other), and stiffen the forms.

ANDRADE (2009) describes in Pl 0.000.008-9 a quick coupling for joining device and for concrete formwork for columns, joining devices and concrete formwork, with locking and bending (or casting) pin, providing faster assembly and disassembly

shape, as well as perfect connection between the parts of the formwork, as well as tightening the formwork and joints together according to the need and pressure exerted to bring the formwork walls closer to the apex of the quick coupling.

The piece consists of an inverted double "U" that can be made of various materials such as bent sheet steel, plastic,

fibers etc., provided that they are capable of being made and have sufficient strength for their intended purpose, ie joining the main rafters to the secondary rafters in the assembly of concrete forms in the building industry without the use of nails. The union of these rafters, using the joint, brings several advantages to conventional systems:

- Dispenses the use of nails and screws to join the pieces;

- It brings significant savings in the execution time, both in the assembly and in the deformation;

- The durability of the rafters is extended, since as no nails are used, no strokes and efforts to remove them are necessary.

The part is mounted first-hand on the main rafters and then the secondary rafters are fitted on top. These parts are fixed at an angle of 45Q or 90Q. Thus, assemblers do not need to use nails or screws, facilitating both assembly and disassembly. List of Figures

The characterization of the present utility model patent document is made by means of representative drawings of the rafter joint so that the product can be fully reproduced by suitable technique, allowing full characterization of the functionality of the claimed object. From the elaborated figures that express the best way or preferential way to realize the product idealized now, the descriptive part of the report is based, through a detailed and consecutive numbering, where it clarifies aspects that can be understood by the adopted representation, of clearly determine the intended protection.

These figures are merely illustrative and may vary, provided they do not depart from the original claim. In this case one has to:

The proposed piece comprises a rectangular plate (1), where four cuts (2) have been made by removing the corners, giving rise to ears which are bent in opposite directions, to form an upper "U" socket (3) and a lower "U" socket (4), offset from each other by 90 °; such that a rafter (5) may be seated in the upper housing (3) and a rafter (6) in the housing (4) such that the rafters are orthogonal to each other.

Claims (4)

1. - CABLE JOINT PART, characterized in that it comprises a rectangular plate (1), where four cuts were made (2) removing the corners, giving rise to ears that are bent in opposite directions, so as to forming an upper "U" socket (3) and a lower "U" socket (4), out of phase with each other by 90 °; such that a rafter (5) may be seated in the upper housing (3) and a rafter (6) in the housing (4) such that the rafters are orthogonal to each other.
