Abstract

Improvements introduced in the invention patent 200200694 for "extensible scaffolding bracket". Improvements that consist of disposing on the end of the tubular profile (2), which is removable telescopically with respect to the tubular profile (1), of a clamp (13), which can rotate in relation to said profile (2) , and that has a clamp (14) welded to it. Thanks to said bushing assembly (13) and clamp (14), the wild boar can be held from above and below. On the other hand, on the end of the tubular profile (1) a clamp (5) has been arranged which allows a fixation of the relative position of the tubular profiles (1) and (2), thus achieving a better load distribution.

Description

Improvements introduced in the invention patent nº 200200694, by: "Extensible scaffolding bracket".

Object of the invention

The present invention aims at a series of constructive improvements of corbel for extensible scaffolding object of the patent 200200694, which presents the characteristic of adapt to the separation between the scaffolding and the facade.

Characterize the present invention, thanks to the improvements object of the present addition, the possibility that has the lower boar rotate 360º, being able to support both Above as below.

On the other hand it also allows to fix the length extracted from the horizontal telescopic section.

Therefore the present invention is circumscribes within the scope of devices or media used in the assembly of scaffolding in order to get a Better distribution of efforts.

Background of the invention

With the bracket described in the invention 200200694 two difficulties are faced, on the one hand, the impossibility of turn the lower boar, allowing its support in any other plane other than the one marked by the plate that had been welded on the lower end of the removable tubular element. That is the plate (2.1) forces the boar (12) to be held in a point inferior to it and arranged in the same plane defined by the platen.

On the other hand between the tubular sections (1) and (2), where the (2) is telescopic removable in relation to the (1), no means have been provided to prevent displacement relative of both tubular profiles, which is difficult in the distribution of charges.

Therefore the objective of the present invention is to improve the bracket already described in the invention 200200694, where it has proceeded to have some means that allow greater versatility in the support of the wild boar lower, and better fixation of the relative position between sections of tubular profiles.

Description of the invention

The proposed invention of corbel improvements for extensible scaffolding described in patent 200200640 consists in a series of improvements which we will describe.

On the end of the inner tubular profile, the which is removable a bushing is arranged, of diameter such that the end of said tubular profile is passed inside inside. Said bushing presents a clamp to him, U-shaped open and perforated on its sides. Perforations  which are used for joining and turning the telescopic tube of the lower boar.

Said bushing can rotate on the profile tubular interior, allowing the fastening of the lower boar to any point.

On the other hand at the end of the outer tube from which it comes, another tubular profile is extracted telescopically, It has a clamp that has a means of fixing the extraction of a tubular profile with respect to the other, thus achieving a better distribution of efforts.

As a result of loading the bracket, and the inner tubular profile be flexed, which is why the bushing connecting the lower boar with the tubular profile inside, it can slide along said tubular profile, so it is not would transmit any effort to the lower boar. With the object of limit the degrees of freedom of movement of the bushing inner tubular profile is why using the planks arranged on scaffolding, displacement is limited longitudinal of the bushing, mainly between the own bushing and the plate on its end has the profile inner tubular

Description of the drawings

To complement the description below is going to be done and in order to help a better understanding of its characteristics, is accompanied by the present specification, of a set of planes in whose figures, illustratively and not limiting, the most significant details of the invention.

Figure 1. Shows a complete representation of the corbel, where the improvements made have been incorporated.

Figure 2. Shows an enlargement of the detail TO.

Figure 3 Shows an enlarged detail B.

Figure 4 Shows the representation of the section Telescopic extendable of the lower boar.

Preferred Embodiment of the Invention

In view of the figures described then a preferred embodiment of the invention proposal for improvements in the invention patent 200200694.

Figure 1 shows the bracket for scaffolding, consisting of two tubular profiles (1) and (2) one inside on the other, that one of its ends is anchored to the bar of the scaffolding (11) by means of the anchor (9), in addition, it has a wild boar (12) and a vertical profile (8) that closes the triangle.

The wild boar (12) is fixed at a point near the end of the horizontal tubular profile (1) and rest on its end opposite (7) on the vertical bar (11) of the scaffolding. To obtain a good support of the wild boar (12) on the vertical bar (11) of the scaffolding, the end (7) has the shape adapted to the section of the scaffolding bar.

Between the fixing point of the wild boar (12) with the horizontal support tubular profile (1) and its end Last there is a space for a perforated plate (1.1). At end of said tubular profile (1) a clamp is arranged (10) (Figure 2).

At the end of the tubular profile (2), which It is arranged internally to the tubular profile (1) and is removable telescopically, a set consisting of a bushing (13) and a clamp (14). The bushing (13) can slide and rotate on the tubular profile (2), and on said bushing is welded a clamp (14), perforated in its extremes (Figure 3)

Below the wild boar (12) it has been arranged another consisting of two sections (3) and (4) extensible in shape telescopic where the (4) is arranged outside the (3). Said tubular profile (3) at its lower end has a clamp (5) that allows to fix the relative position of both sections, while at the upper end it presents a clamp (15) in the form of "U" that has the plates that make up the "U", perforated.

The perforations of the clamp (15) and the clamp (14) that is welded to the bushing (13), allow the union between the tubular profile (4) and the (2).

The possible sliding of the bushing through the inner tubular profile before the flexion of its end by the fact to load it, it is limited by providing some limiting elements, such as for example planks, between the bushing itself and the plate extreme, and another between the bushing itself and the clamp (10).

This description does not become more extensive, in the good to understand that any expert in this area would have enough information to understand the scope of the invention and its derived advantages, as well as to proceed to reproduce the same.

The invention, within its essentiality, can be put into practice in other embodiments that differ in detail from that indicated by way of example of the description, and which will also achieve the protection that collect. Likewise, it can be built in any shape and size with the most appropriate materials, to be all included in The spirit of the claims.
