ES2221516A1 - Anchor for fixing corrugated sheet and support tube, has screw bolt provided with twist lock mechanism, and semicircular lower bearing attached to screw bolt via nut - Google Patents

Abstract

The anchor has a screw bolt (1) provided with a twist lock mechanism (2). A semicircular lower bearing (3) is attached to the screw bolt via a nut (4).

Description

Anchoring for corrugated roof plates by the bottom.

The present invention relates to a screw which serves as an anchor for corrugated sheets covered by the lower part of the support tube, having improvements that affect the simplification in placement, since you can do it only one person, which greatly affects the safety of the operator as well as economically, due precisely to this circumstance.

Background of the invention

The different anchor models are known currently used and that presents great difficulty when it comes to place it, since all of them are anchored at the bottom of the support tube and screwed by the top being for it the employment of two people is necessary, one of which must operate from below and another on the corrugated iron of deck, which to Sometimes it is dangerous and certainly more laborious and expensive. In sometimes the fragility of the support tube or the plates corrugated roofs of little thickness complicates both the process of  placement to be recessed by brickwork.

To avoid the inconvenience of this type of sheet anchors, the holder of the present invention has designed an anchor screw improving the current whose characteristic is a set consisting of two pieces whose part semicircular bottom is coupled to the support tube allowing its fit here and on the top fits the iron corrugated roof, interposing between it and the nut a rubber washer that prevents liquid filtration.

However, experience has shown that it is possible Improve the characteristics of the existing model and so so much has been devised a new one whose characteristics are the object of The present invention.

Description of the invention

The anchor screw for corrugated plates covers is characterized by having stud bolt whose head it has two bumps or tips at the bottom of it and at the other end a thread where the nut will be attached.

There is another piece of sheet metal whose half It has a semicircular shape (it can be of different radii depending the size of the tube where it is to be attached) and the other half has a groove of a width equal to the diameter of the screw asparagus.

Brief description of the drawings

What is accompanied as an illustration of the This report shows five details of the elements of the anchor for corrugated plates of roofs at the bottom for a better understanding of how much is described as example. A case study of it is represented.

Description of a preferred embodiment

The anchor in question basically consists of Two pieces Made of sturdy metal.

One of them is a head stud (1) round (5) at the bottom of which it has two protuberances or tips (3) whose purpose is that, by tightening the nut (2) that will finally fix the mechanism, they are nailed slightly on the corrugated iron (9) and thus avoid asparagus turn (1), which makes the main possible characteristic of this invention, which is to make the operation feasible from under the corrugated iron deck and prevent a Second person is necessary to carry out the operation. I know has decided that these two bulges (3) are the ones used to prevent unwanted rotation of the stud (1) when tightening the screw because this allows to interpose a rubber washer (4) between the screw head (5) and the corrugated iron (9) avoiding leaks of water or other liquids. The protrusions (3) penetrate the rubber washer (4) to stay later on the corrugated iron of cover (9) remaining this between both of them and making the junction tight - Fig. 3.

This mechanism eliminates the inconvenience would present a safety washer would have been used traditional, since in that case when introducing the rubber is not I would have managed to avoid the turn, or by doing without it I don't know I would have got the seal.

The second main piece of this mechanism of Anchoring is a metal sheet (8) at one of whose ends has a semicircular shape that attaches to the support tube of the metal structure (10) on which the plates will be placed corrugated roof (9). The radius of this piece may vary in function of the diameter of the tube, although they do not necessarily have to coincide. It may also have other shapes depending on the tube (square ... Etc.). On the other end of this piece (8) there is a slot (7) where the stud bolt (1) will be inserted. The reason of this slot is to give a margin of error when drilling in the corrugated iron of cover or depending on the diameter of the tube and in this way approximate the axis of the bolt screw (1) to the tube support (10) and thus give greater consistency to the anchor.

Finally we will interpose a metal washer (11) and using a nut (2) we will definitely fix the anchorage. A moth could also be used to do more comfortable placement, being subject to a matter of resistance and economy since its manufacture would be more expensive, although it would save costs in its placement.

The summary of the execution of the fixation of the corrugated iron from cover to support tube would be:

to)

In relation to the metal structure calculate the distance where the Drills and do the same.

b)

Enter the stud bolt (1) in the hole, interposing before both the rubber washer (4).

c)

Place the iron corrugated roof (9) on the metal structure.

d)

Enter by groove of the support plate (7) the bolt bolt (1) coupling the semicircular part of the other end holding the tube.

and)

Put the washer, and approximate as much as possible the stud bolt (1), taking advantage of the groove (7) and place and tighten the screw (two).

This way the purpose is achieved Fundamental of this invention:

one)

Perform all the assembly operation with greater comfort in relation to how It currently does with known mechanisms.

two)

The execution of work is done by a single person so it is a huge cost and time reduction

3)

By preventing a person working on the plates avoid accident hazards in a considerable way.
