Abstract

Construction strut, including a lower tube inside which telescopes an upper tube with pairs of holes to adjust its height with the help of a pin that is inserted in one of those pairs of holes, and including a nut with valona that said nut engages in an upper section of the lower tube, characterized in that it includes a support washer (7) that is sandwiched between the pin (4) and the flange (5) of the nut (6); all this in order to facilitate the stripping by releasing the load of the strut by striking laterally on the support washer (7) without having to unscrew the nut.

Description

Construction prop.

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a prop for type construction incorporating two coupled tubes telescopically with the peculiarity that it incorporates a support washer that is intended to facilitate substantially the decoupling operation quickly and simple.

The struts basically comprise two tubes telescopically coupled: a lower one that rests on the ground and another superior where it supports the surface to prop up, so that the height of the strut is regulated in principle with the help of a pin which is inserted into one of several pairs of tube holes upper, resting the pin in turn on the wall of a nut  Threading the upper section of the lower tube, nut through which can be adjusted the height of the strut.

Background of the invention

Construction struts come used for shoring in the works, to hold formwork panels, beams, etc. These struts are configured  usually by two telescopic tubes.

The upper tube has a series of holes arranged at a certain distance where a Barrette. In its upper part a plate is provided that is the which performs the corresponding support of the formwork panel, beam or surface to prop up.

The lower tube also has a plate of  support at its lower end to perform support on the ground. At its opposite end it has a threaded area for the coupling of a nut with internal thread, which has some handles that facilitate the rotation of said nut and existing also in said nut a wall in its upper part.

The pin will be inserted in one of several pairs of holes in the upper tube, depending on the height of the strut, then using the nut to fine tune that height, resting the pin on the nut wall.

To perform the formwork, turn in in the opposite direction to tightening the fixing nut so that slowly the relative position of the upper tube will decrease with regarding the position of the lower tube.

This decoupling operation is slow and in sometimes it is done with great difficulty due to one's own  pressure to hold the nut.

Description of the invention

To achieve the objectives and avoid drawbacks mentioned in the previous sections, the invention proposes a construction strut that is characterized because it incorporates a support washer that substantially facilitates the formwork.

The strut comprises two coupled tubes telescopically: a lower one that rests on the ground and another upper where it supports the surface to prop up.

The lower tube incorporates in its upper section a thread where a nut with wall is attached where it rests on start a pin located in one of the pairs of holes in the upper tube according to shoring height, tuning that height after using the nut.

The washer is sandwiched between the pin and the Walloon of the nut, so that at the time of decoupling, in instead of having to initially turn the nut, it will first hit laterally on the support washer. thus releasing the load to the one under the strut. Then you can turn the nut if desired, but no load on the referred strut.

The washer is characterized in that it includes minus a couple of steps facing his upper face where will support the pin, presenting in turn the lower face of said Washer a surface with several different planes.

The lower surface is also characterized because it can comprise a single arched plane and also several different arched planes.

The strut being subjected to a load, for release it will hit the washer by moving it to a advanced position where the pin will stop leaning on a upper step of the washer staggering to be placed in a lower step in a released position where the pin will be faced with a lower seat of the respective staggering of the washer, whereby the upper tube is will move instantly, down freeing from the load.

Next to facilitate a better understanding of this descriptive report and being an integral part of the same accompany some figures in which with character illustrative and not limiting the object of the invention.

Brief description of the drawings

Figure 1.- Shows a view of the strut for construction of the invention in a loading position.

Figure 2.- Shows a view of the strut in a position released.

Description of the preferred embodiment

Considering the numbering adopted in the figures, the construction strut is determined from two tubes telescopically coupled to each other: a lower one 1 that supports on the ground and another upper 2 where it supports the surface to shore up.

The upper tube 2 incorporates pairs of holes facing 3 where a pin 4 is inserted according to the height desired from the strut, seating pin 4 on wall 5 of a nut 6 with interposition of a support washer 7, the nut 6 coupled to a thread 8 located in the upper section of the bottom tube 1.

With this nut 6 you can fine tune the height of the strut.

The support washer 7 includes on its upper face  pairs of facing steps 9, in one of which will support pin 4 while the lower face will sit on the wall 5 of the nut 6.

To ensure a stable position of the washer  support, its lower face has at least two portions forming obtuse angle close to 180º, one of them 10 with a slight inclination that is just below the staggering 9.

This is that in the active position of the strut, the stepped seat of the washer 7 where it is supported pin 4 is positioned with a slight inclination with with respect to a horizontal plane in order to prevent a accidental displacement of washer 7, which would stop the strut be effective.

Thus, for example, using pin 4 the position shown in figure 2, and the upper tube being setting the formwork position of the respective panel, the formwork will be done by hitting the washer so that the pin then occupies another position supporting one more step lower. In this way a rapid displacement of the upper tube with respect to the lower tube, without having to act on the adjusting nut 6, as already mentioned previously.

Claims (2)

1. Construction strut, which includes a lower tube inside which an upper tube with pairs of holes is telescopically coupled to regulate its height with the help of a pin that is inserted into one of those pairs of holes, and including a walnut that said nut is coupled in an upper section of the lower tube, it is characterized in that it includes a support washer (7) that is sandwiched between the pin (4) and: the wall (5) of the nut (6); all this in order to facilitate the release of the strut by releasing the load of the strut by striking laterally on the support washer (7) without having to unscrew the nut. 2. Construction strut according to claim 1, characterized in that the upper face of the support washer (7) where the pin (4) is supported includes pairs of facing steps (9), on one of which the pin (4) will rest. in the active position of the strut, while the lower face of the support washer (7) has at least two portions forming an obtuse angle, one of them (10) arranged below the steps (9), which in the active position , the seat of these steps (9) will have a slight upward inclination to ensure a stable position of the support washer (7) and the strut assembly.
