Description

Davit for safety nets.

Field of the Invention

The present invention, as expressed in the set forth in this specification, refers to an element davit for securing construction safety nets of concrete buildings and structures, whereby securely and easily secure the network used as a means of security, preventing the fall of materials and even avoiding possible operator falls to the planes lower.

State of the art

During the assembly of concrete structures the installation of safety nets on its edges is required to prevent the fall of people or material over the levels lower. To do this, inverted L-shaped dams are placed at  which hook safety nets that collect the material and stop the fall of the workers.

The davit for securing safety nets  existing in the market are built in a single piece in L-shape, for example in the davit shown in the model of utility ES 1025507 U, which makes them occupy a large space of storage, and force to always set the same security network configuration, not being able to adapt to different heights more than with the construction of new davits of the corresponding size.

Description of the invention

The davit of the invention solves these problems through a change in the structure by which build the davit from removable parts, of tubular constitution, which are finished off at one end of a portion of internal section equal to the external of the opposite end, allowing its coupling by partial plug. Different parts are conveniently fastened by a pin system or screws, entering through opposing holes of Pluggable portions. This allows its disassembly preceding to storage, which considerably reduces space occupied, and also allows the assembly of more or less pieces to change the height of the davit and vary in this way the configuration of the safety net, adapting it to the needs effective.

According to the invention, the assembly of the davit from a variable number, generally three, straight section extension elements tubular, which make up the greater side of the L, one of whose ends have an internal section corresponding to the section external of the opposite, to facilitate the assembly by plug of adjacent ends. To ensure the resistance of said assembled, the union of the straight elements is carried out by means of a screw and nut assembly or an introducible pin through facing holes that have pluggable ends.

To the upper end straight element of the sequence Straight extension elements are coupled, also by plug partial, a section angled at right angles, whose free end is it also attaches a straight horizontal arm, which forms the short side of the L.

On the angled section and the horizontal arm of the davit four metal plates fixed by means are placed convenient, for example soldier, two in each section, which serve as support, by means of a screw or pin, to a metal brace that performs the reinforcement of the structure.

On the angled section and on the horizontal arm of the davit three rope fastening tools are placed security, being able to install a higher number. These useful they are fixed to the davit structure by screws or other equivalent consolidation method, for which they are performed anchor holes on the outer face of the corresponding sections, at the points where you want to place the tools of subjection.

Description of an embodiment

Figure 1 shows the final assembly of the davit for safety net, in which several have been installed straight elements (1) of substantially square section, in this case two, fixed together by a screw assembly and nut, pin or any equivalent system. To the extreme The upper part of the set of straight elements (1) is a section angled (2), whose upper branch (15), of reduced length, is assemble the horizontal arm (3) straight from the davit.

Both the angled section (2) and the arm horizontal (3) have plates (4, 5) firmly attached to the same, for example by soldier. In these plates (4, 5) the ends of a metal tie (6) are fixed, by means of a pin or any other equivalent method.

On the angled section (2) and the horizontal arm (3) of the davit are fixed by screws (8), fastening tools (7) of the safety net rope.

A straight element is shown in figure 2 (1) of the davit, in which the outer section of the lower end (11), corresponding to the inner section of the upper end (10) so that it can be introduced into the straight element (1) anterior and joined by a pin or screw through its lower through hole (12) and through hole upper (13) of the straight element (1) above.

Figure 3 shows the angled section (2) of the vertical branch of the davit, in which the section of its lower end (14), corresponding to the internal section of the upper end (10) of the previous straight element (1), with which It is fixed by means of the corresponding screw or pin. The horizontal branch (15) of the angled section (2) has a section internal corresponding to the outer section of the horizontal arm (3), which will fit inside, being fixed by a pin or screw

Two plates (5) are secured by welding to the internal side of the angled section (2), serving as support for the brace (6) that reinforces the profile in formed square by the horizontal arm (3) and the angled section (2).

On the outer face of the angled section (2) practice at least one hole that will serve as an anchor point for the corresponding clamping tool (7) of the net rope security, being able to increase the number of holes to increase the configurations of the network realizable through the davit.

The horizontal arm (3) of the davit is shown in figure 4, in which the plates (4) are appreciated fix the tie rod (6) and the placement of two fastening tools (7), being able to place more, for which several perforations in the upper face of the horizontal arm (3) that they will serve for the introduction of the screws (8) of the tools of  support (7).

Figure 5 shows in detail the tool of clamping (7), consisting of a small tubular segment (16) metallic of internal section slightly larger than the external of the horizontal arm (3) or of the angled section (2) to allow its sliding towards the anchor point. On one side there is a hole to which a nut is welded to introduce a screw (8) that will fix the tool in its position. On the border opposite is a ring (9) that will serve to hold the  safety net rope.

Describe the nature of the invention, as well as how to do it in practice, should be noted that the provisions indicated above and represented in the attached drawings, are susceptible to modifications of detail as long as they do not alter its principle fundamental.
