Description

Jaw improvements for the placement of bodyguard in construction works.

Object of the invention

The present invention, as follows from stated in this report, refers to some improvements introduced in a gag that is placed on construction sites to position the vertical railing posts on it provide protection for operators in places where it exists falling risk.

Background of the invention

The same applicant owns a patent P200701873 describing a jaw for placement in the beams that make up the formwork structure, to be placed in any part of the perimeter of the formwork, in window recesses or in retaining walls; making sure by means of two claws, one of they movable, being able to regulate the position of the latter to adapt to the structure where the jaw will be placed, generally in the sopandas located in the perimeter of the formwork, also being able to position in the concrete already set to protect the gaps of windows or walls.

The aforementioned gag can work in two anchor positions, horizontal or vertical, depending on the construction needs, by having two receiving cylinders that They support the posts that make up the railing. These elements are placed, one on top of the mobile and supportive claw with its movement; and another horizontally, in a lower plane to the rectangular profile that serves as the basis for the configuration of jaw.

Description of the invention

The inconvenience presented by the previous invention is that with its configuration it is not possible to anchor in certain types of beams that are used for certain civil and industrial constructions and that present profiles in "I", "H" or "T", composed of a central soul and wings on the top and bottom, or only on the part upper ("T" profile).

In these cases the previous invention would not work  for anchoring in certain positions where the claws of tightening they have no structure to hold by the special configuration of this type of beams. To anchor the jaw in horizontal position to the beam in "I" and "T", as well as to be fixed to beams in "H", in an upright position, it is for That this new gag is created.

In the previous invention the receiving cylinder perpendicular to the base is located above the movable claw and linked to its movement, predetermining this fact the position of the railing post that is inserted into the cylinder, which will always be on top of the wall, blow or beam that It serves as an anchor. Sometimes it will be necessary for the railing away from the anchoring element, for example, located towards the inside the work, being the beam outside the perimeter of the same.

To solve this disadvantage, the invention presents a new configuration of the vertical receiver cylinder, placing it in the base profile independently, being able to be set along the profile according to the needs of distance of the railing with respect to the body on which it Make the anchor.

Description of the drawings

To complement the description that is being performing, and in order to help a better understanding of the characteristics of the invention, the present specification is accompanied Descriptive drawings showing the preferred embodiment, where, for illustrative and non-limiting purposes, it has been represented the next:

Figure 1.- View of the jaw object of the invention, with a representation of the profiles of the beams in "H", in "I" and in "T".

Figure 2.- Shows a jaw that is secured in  a section beam in "I".

Figure 3.- View of a clamping jaw to a "H" profile beam, vertical anchor.

Preferred Embodiment of the Invention

The jaw configuration has a base  rectangular tubular (1) through which an element of mobile clamping configured by a rectangular tubular portion of larger section than the base (2), joined by means of a piece rectangular arranged in its lower part (3) to a claw (4) materialized in a "U" plate folded at its ends towards the inside of the tightening zone, and in position perpendicular to the base (1).

The fixed clamping element of the jaw, complementary to the previous one, it is arranged at one end of the base tubular (1), configured by a rectangular piece (3 ') attached to the base, piece in which a claw (4 ') of identical forms and facing the one that presents the element mobile.

The position of the moving part and the fixing of the jaw is determined by a threaded rod (5) of smaller length than the base (1), fixing the rod in one of its ends welded to the top of the tubular portion rectangular (2) of the moving part, establishing the connection with the fixed part being its other end inserted in a drill that It is arranged on the top of a rectangular piece (6) that plug the mouth of the base end.

The regulation of the jaw movement will be through a nut (7), preferably of butterfly, which moves through the threaded rod causing the movement of the moving part and tightening the jaw in its function of fixing to the desired structure

Two cylindrical tubular elements are arranged (8, 9) to be connected to the railing posts; one in horizontal (8), at the bottom of the rectangular piece (6) located at the mouth of the base. Another cylindrical tube (9) is scrolls through the rectangular profile arranged vertically with respect to the base (1), and outside the tightening zone, movement possible when welded on a hollow rectangular body (10) of greater section than the base on which it travels, being fixed in the desired position in the base profile (1) using a screw with head lock allowing manual tightening (11).

With the mission of fastening the jaw to the wings (14) of the beams, are provided at the bottom of the base (1), on top of the rectangular pieces (3, 3 ') and perpendicular to them, flat paths (12, 12 ') folded in their middle part forming an angle between 90º to 120º, fixed welded in one of the sections to the rectangular piece protruding the other from its vertex, to accommodate the edges of the beam wing to which the jaw will be attached.

The jaw can be placed, depending on tighten its claws, horizontally, in the cases of beams  section in "I" (Figure 2), or in "T", placing the base of the jaw on top of one of the wings (14) of the beams for place the railing post (13) on the cylindrical element mobile (9); or vertically, for beams cases in "H", because this is the position of the wings in this type of beams, introducing the railing post (13) in the cylindrical element of the end of the base (8). When used of this way, the movable cylinder (9) can be removed from the jaw, when not be accurate in this application (Figure 3).

It must be understood in the figures that it is accurate the placement of several jaws on the beams to form the railing, preferably every three meters.

This gag presented is also valid for anchoring in sopandas or walls, not being an obstacle in these cases the presence of folded plates (12, 12 ') by allowing the "U" claws (4, 4 ') of its initial structure the settlement.

It should be understood that the invention has been described according to the preferred embodiment thereof, whereby may be subject to changes in shape, size and materials, as long as these alterations do not vary substantially the features of the invention that are claimed then.
