Anchorage system for guardrail

Abstract

ovided for fixing the guardrail tubes for the building works. The anchorage system includes a body member having a recess, an end portion being formed thereof locations allowing to receive screws fitting therewith for be fixed in a wood casing before that the concrete be poured therein and that the casing be removed thereof, a cavity, and grooves. The recess receives an end tube provided of a rod and being formed as integral part of a guardrail tube. The end tube is blocked therein the cavity by the rod sliding therein grooves, and for that the end tube be blocked therein, the guardrail tube is rotated and fixed to the braces. The same anchorage system is also used with a fastening device for connecting a safety harness in a concrete slab.

Description

This is a continuation of the application No. 61/068,278.

BACKGROUND OF THE INVENTION

[0001]1. Field of the Invention

[0002]The present invention relates to an anchorage system conceived for fixing the guardrail tubes for the building works.

[0003]2. Description of the related art

[0004]A search of prior art records has unveiled the following patents: [0005]CA 1,147,585 issued in 1983 to Sanchez Velasco; [0006]U.S. Pat. No. 6,761,002 issued in 2004 to Sorkin; [0007]U.S. Pat. No. 6,109,597 issued in 2000 to Sicking et al.; and [0008]U.S. Pat. No. 4,037,384 issued in 1977 to Molyneux.

SUMMARY OF THE INVENTION

[0009]It can be deduced that the presently existing systems do not afford a complete security and can cause loss of human life.

[0010]It is therefore an object of the invention to provide a new anchorage system which give a complete degree of safety, and which can be obtained with the system being discussed in the present disclosure. The anchorage system comprises a body member having an end portion being formed thereof locations allowing to receive screws fitting therewith for be fixed in a wood casing before that the concrete be poured therein, and that the casing be removed thereof. The body member is constructed for receiving an end tube provided of a rod and being formed as integral part of a guardrail tube. The end tube is blocked therein a cavity by the rod sliding therein grooves, and for that the end tube be blocked the guardrail tube is rotated vertically and fixed to the braces.

[0011]The same anchorage system is also used with a fastening device for connecting a safety harness in a concrete slab.

[0012]The foregoing and other objects, features, and advantages of this invention will become more readily apparent from the following detailed description of a preferred embodiment with reference to the accompanying drawings, wherein the preferred embodiment of the invention is shown and described, by way of examples. As will be realized, the invention is capable of other and different embodiments, and its several details are capable of modifications in various obvious respects, all without departing from the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0031]Referring to the FIGS. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, and 16, it is shown the body member including a recess (4), an end portion (3) being formed thereof locations (5) allowing to receive screws (16) fitting therewith for be fixed in a wood casing (15) before that the concrete be poured therein and that the casing (15) be removed thereof, a cavity (1), and grooves (2).

[0032]The recess (4) receives an end tube (8) provided of a rod (10) and being formed as integral part of a guardrail tube (6). The end tube (8) is blocked therein the cavity (1 ) by means of the rod (10) sliding therein the grooves (2), and for that the end tube (8) be blocked therein, the guardrail tube (6) is rotated vertically and fixed to the braces.

[0033]Further, the tube (6) is provided of metal pins (7) for fixing the braces, a ring (11) for hanging construction elements, and a reinforcing plate (9) which is welded therebetween the tube (6) and the end tube (8).

[0034]Referring to the FIGS. 14, 15 and 16, it is shown the fastening device for connecting a safety harness, which includes a ring (12) welded to a plate (13) in which is introduced a tube (14) provided of a rod (18).

[0035]Referring to the FIGS. 17 to 18, it is shown the fastening device in operation, and for that the fastening device be blocked therein, the device is rotated and screwed therein the end portion (3) by means of the plate (13) as shown to the FIG. 20.

[0036]Referring to the FIG. 19, it is shown the installation of the body member in a wood casing (15).

[0037]Referring to the FIG. 20, it is shown the installation of the fastening device in a concrete slab (17).

[0038]Although only a single embodiment of the present invention has been described and illustrated, the present invention is not limited to the features of this embodiment, but includes all variations and modifications within the scope of claims.
