FR 3 061 727 - A1 (57) One of the elements (1) of the metallic structure of the deck has two additional parts (2) fixed (3) inside the metallic element (1).

It has another element of the metal structure of the deck with two additional parts attached to the outside. In such a way that it is possible to assemble the two metallic elements, because they are different but with a complementary configuration.

The elements (1) only this fixes them.

The other elements only this fixes them.

It has vertical suspension rods fixed to the retaining cables only for the elements (1) and also it has vertical suspension rods and the retaining cables only to the other elements.

The present invention relates to a new way of constructing a suspension bridge.

On drawing 1, we can see a hanging bridge with three hanging spans

In drawing 2, we can see a suspension bridge of single suspended spans.

On drawing 1, one can see a suspension bridge which is composed of the following elements; the bridge deck (6), two pillars (2), (3), two retaining cables (4), a cable on each side of the deck and the vertical suspension rods (5).

Also in drawing 1 we can also see the two sides of the river (1) and (8), and the river (7).

We can also see in drawing 1, the bridge piers (2) and (3), which are fixed in the river (7).

In drawing 2, we can see that the bridge also suspended from the bridge deck (6), two pillars (10) and (11), two retaining cables (4), a cable on each side of the deck and the rods vertical suspension (5).

In drawing 2, it can be seen that the two pillars (10) and (11) of the suspension bridge are fixed to the ground.

The suspension bridges in drawings 1 or 2, the deck (6) is attached by two retaining cables (4) for the intermediary of vertical suspension rods (5)

These construction elements (4) (5) work together, which allows the bridge deck (6) to be suspended.

The retaining cables (4) are fixed to the anchor block (9).

The pillars (2), (3), (10), (11) consist of two lateral parts (14), (15) and metal parts (16) which connect the two lateral parts (14), (15) and the retaining cables (4) are fixed, on the top, of the pillars (2), (3), (10), (11) as we can see in drawing 3.

-2The two lateral parts (14) and (15) are inside hollow (17), only with a metal contour (18), as we can see in drawing 4. This means that the forces on the lateral pillars (14), and (15) are on the perimeter (18) and not in the center (17).

In drawing 5, we can see in detail the metal structure of the bridge deck (6) with retaining cables (4), and the vertical suspension rods (5).

In drawing 6, one can see an element (19) of the metallic structure of the deck. And in drawing 7, we can see this same element (19) in another view.

There are suspension bridges with pillars (10), (11) fixed on the ground, as we can see in drawing 2 or pillars (2), (3) fixed in the river as we see on in the drawing 1 and this situation is due to the width of the river.

The river is very wide, the distance between the two pillars (10) and (11) is very large and it is impossible to build a bridge as seen in drawing 2 and therefore it is necessary to build a bridge as seen in drawing 1, with the bridge piers (2) and (3), which are fixed in the river.

Fixing the bridge piers in the river costs more money if the piers are placed on the ground. Also handling is more expensive if the pillars (2) and (3) are fixed in the river (7).

Because the efforts are very large, it has a technical limitation of the construction elements of the suspension bridge such as the vertical suspension (4) and the retaining cables (5) to build a bridge with a greater distance between pillars (2) , (3) or between the pillars (10), (11).

The present invention aims to build a suspension bridge with a greater distance between the two pillars (2), (3) and (10), (11), and it is possible to avoid pillars in the river.

-3The present invention aims, when the distance between the two sides (1) and (8) of the river are very large and therefore it is necessary to build a bridge as in Figure 1, but we can build a bridge like the Figure 2 despite the large distance between the two sides sides (12) and (13) or build a bridge as in Figure 1 but with a greater distance between the pillars (2) and (3).

The present invention also aims to build a new suspension bridge where there is already a suspension bridge, with integration between the two bridges.

To build, as mentioned above, the set of vertical suspension rods (5) and the retaining cables (4) and the deck (6) they will have a different configuration.

The accompanying drawings illustrate the invention.

Drawing 1 represents a suspension bridge with three suspended spans.

Drawing 2 represents a suspension bridge of single suspended spans.

Drawing 3 represents a pillar of the suspension bridge.

Drawing 4 shows in detail a pillar of the hanging bridge.

Drawing 5 shows the metal structure of the suspension bridge deck.

Drawing 6 shows an element of the metallic structure of the deck.

Drawing 7 shows a further view of an element of the metallic structure of the deck.

Drawing 8 shows an element of the metal structure with an additional part.

Drawing 9 shows an element of the metal structure with an additional piece fixed outside.

Drawing 10 represents the elements of drawing 8 and 9 assembled.

Drawing 11 represents several elements of drawing 8 and 9 assembled.

Drawing 12 shows several elements of drawing 8 and 9 assembled and the cables.

-4To have a greater distance between the two pillars (2) and (3) and also (10) and (11), the bridge has a different metallic element.

The metallic element (19) is different because each one (20) and (23) have two additional parts (22) and (25) as we can see in drawings 8 and 9.

In drawing 8, we can see an element (20) of the metallic structure, of the bridge (6) but that it has an additional part (22) that is fixed (21) inside the element (20).

In drawing 9, we can see a further element (23) of the metallic structure of the bridge (6), but that it has an additional part (25) that is fixed (26) to the outside of the element (23) . It also has a perpendicular edge (24) to fix the retaining cables (5), if necessary.

The metallic element (20) will only be fixed to one further metallic element (20) and the metallic element (23) will only be fixed to one further metallic element (23) and these parts successively.

But the further metallic element (20) is not the neighbor, because it is interposed by a metallic element (23) and successively.

Also the further metallic element (23) is not the neighbor, because it is interposed by a metallic element (20) and successively.

In drawing 10 we can see the assembly of two metallic elements (20) and (23).

In drawing 11, we can see the assembly of several metallic elements (20) and (23) so as to have an apron (6) of a suspension bridge.

On drawing 11 on the right we can see the number (20) and (23) successively and in between and its signifies the interposed assembly of the metallic elements (20) and (23). The first metallic element (20) is fixed (27) to the following metallic element (20) with the additional part (22) for soda, rivet (27), etc. The additional piece (22) goes into the neighboring metallic element (23) and the additional piece (22) has a length that reaches in the middle of the next metallic element (20).

-5Likewise the first metallic element (23) is fixed (28) to the following metallic element (23) with the additional part (25) for soda, rivet, (28), etc. The additional part (25) bypasses the neighboring metal element (20) for the exterior and the additional part (25) has a length that reaches in the middle of the next metal element (23).

This assembly of the drawing 11 is repeated successively, to have a bridge deck (6).

The metallic elements (20) and (23) are an example, the configuration can be different, but with the same functional concepts. Also the construction material can be concrete, wood, aluminum, fiberglass, carbon fiber, etc.

The suspension bridge of this invention has metallic elements (20) and (23) which are differently related to the vertical suspension rods (4) and the retaining cables (5).

In drawing 12 we can see the bridge deck with several metallic elements (20) and (23) successively and in between and that the metallic element (20) is fixed (27) has a further metallic element (20) only. Also the metallic element (23) is fixed (28) to a further metallic element (23) only.

Also in drawing 12 we can see two retaining cables (29) and (30). The retaining cable (29) and only fixed to the vertical suspension rod (31) and the retaining cable (30) and only fixed to the vertical suspension rod (33).

The retaining cables (29) and (30) are parallel (24) and / or different altitude and the retaining cable (30) does not touch (32) with the vertical suspension rod (31).

The vertical suspension rods (31) are only fixed to metallic elements (20) and the vertical suspension rods (33) are only fixed to metallic elements (23).

So the efforts on the retaining cables (29) and (30) and the metallic elements (20) and (23) are much less, almost half the

- 6 retaining cable (4), the vertical suspension rod (5) and the metal element (19) and in this way the technical limitations of the bridge elements and cables (4), (5), (19) are resolved with the solution of the present invention.

The efforts of the bridge are half for the elements (20) and these respective cables (29) and (31) and the other half of the efforts of the bridge for the other elements (23) and these respective cables (30) and (33 ).

The bridge can have a greater distance between the two pillars (10) and (11) or (2) and (3), with the solution of the present invention.

Also with the solution of the present invention gives the possibility of placing the new pillars away from the existing pillars (2) and (3) because it is possible to make a bridge with a greater distance between the new pillars.

This gives the possibility of building a new bridge side by side next to an existing bridge.

In drawing 12, the additional part (22) of the metallic element (20) is not represented at the right of the drawing, for the design to be more clarification.

It also has two retaining cables (29) and (30) on each side of the bridge.

In some location of the bridge, it can happen that a vertical suspension (31) is going to fix a metallic element (23) and vice versa, but it is an exception.

The bridge can have pillars (2) and (3) or (10) and (11), with another pillar next to it or with a pillar in the other pillar (2), (3), (10), ( 11) because the pillars (2), (3), (10), (11) are inside hollow (17).

The way to build this bridge is the same as in drawing 1 or 2, the only difference is that the assembly must insert the metallic elements (20) and (23) and to fix a metallic element (20) only with another metallic element (20) and a metallic element (23) with only one other metallic element (23).
