Description

SUPPORT STRUCTURE FOR THE HIGHWAY

20175945 prh 25 -10- 2017

PURPOSE OF THE INVENTION

The invention relates to structures of elevated lanes. Elevated routes are, for example, bridges, road bridges, railway bridges, or railways.

BACKGROUND OF THE INVENTION

In urban transport, elevated routes are known where, for example, trams, local trains or metro trains run locally above ground level. This can be used to create intersection areas or to allow other utilization of the area below the fairway.

Earthquakes or other seismic instabilities pose the risk of a collapsed highway. The damaged passage is difficult to repair and the structures must be rebuilt to the foundations. Restoring the infrastructure of a densely built environment to pre-crisis levels is slow and costly. Slow renovation can make it even more difficult for an infrastructure-based community to recover - passenger and freight problems multiply as local difficulties.

SUMMARY OF THE INVENTION

The object of the invention is to eliminate or at least alleviate the above disadvantages. It is an object of the invention to provide a novel elevated passage and an elevated passage support structure. The invention is characterized in what is stated in the independent claim. Embodiments of the invention are disclosed in the dependent claims.

One aspect discloses an elevated passageway support structure including a passageway cover, at least one post arranged to support the deck, and at least one tensioned support cable arranged to support the post. The deck may be a bridge or part of a bridge. There may be one, several poles, one after the other in the direction of the passage, in pairs, in pairs along the passage, or several adjacent.

The support structure includes a counterweight support cable, the first end of which is secured to the counterweight and the other end to the post. A pivoting means is provided on the cover, comprising means for receiving the drawstring pull from the counterweight in the first direction and means for receiving the drawstring pull from the post in the second direction. The geometry of the counterweight and the support cable defines a threshold for tilting the support structure, whereby when the threshold is exceeded, the elevated passage is arranged to be inclined in a controlled manner. When a force exceeding the limit is exerted on the raised passage, the passage will be inclined.

In one embodiment, the support structure has at least two posts, whereby the passage is inclined such that the surface of the deck faces upward as the structure tilts. In one embodiment, the support structure includes two poles transverse to the longitudinal direction of the passage and inclined so that the lower ends of the posts are spaced apart from the upper ends of the posts. The positioning of the posts can create a geometric structure in which the elevated passageway will fall in a controlled manner so that when the posts fall, the surface of the deck faces upwards. During this tilt, any vehicle that may be present on the fairway is not stuck under a controlled tipping or tilting structure.

20175945 prh 25 -10- 2017

In one embodiment, the limit value for support structure tilt is defined by an earthquake scale. When an earthquake exceeds a predetermined magnitude, the passage is arranged to tilt in a controlled manner. An earthquake-induced force from an appropriate direction can tilt or overturn the passage. The corresponding force may be due to an elevated passage, for example in the crisis area due to the explosive effect of a bomb.

In one embodiment, the pivoting means for swinging the draw wire in the support wire and attached to the cover is a pulley. The pivoting means may be a rounded fixed surface against which the support cable rests and through which the support cable runs from the counterweight to the post.

In one embodiment, the upper end of the post is cylindrical. The top end of the pillar rests against the cover. According to one embodiment, the lid rests on the post with gravity and both the cover and the post are separate components.

In one embodiment, at least one projection is provided on the underside of the cover to restrict movement of the post relative to the cover in a horizontal plane. The protrusion may be a cylindrical pivoting pillar arranged in the lid and positioning the pillar. The projection may be a component attached to the cover or a fixed integral part of the cover.

In one embodiment, the cantilever and the post are connected to each other by a locking member which is interrupted by a force exceeding the limit value. The locking piece is, for example, a break pin.

In one embodiment, there is a block-shaped foundation stone under the post. The lower end of the pillar has a support piece which rests against the foundation stone. A first downwardly extending flange disposed on the first side of the foundation stone and a second downwardly extending flange disposed on the other side of the foundation stone are provided on the edges of the support member, the flanges guiding the post to tilt in the direction of the plane formed between the flanges. The flanges resting on either side of the foundation stone keep the post parallel to the cover and prevent the post from rotating vertically about its axis.

20175945 prh 25 -10- 2017

In one embodiment, on top of the foundation stone of the locking collar is attached to the lower side, and a space is provided between the foundation stone of the at least one support member extending locking nail. The locking claws limit the post from tilting in the direction of the plane formed between the flanges up to the bending limit of the locking claws. The locking claws may break or bend, causing the posts to tilt. The locking claws may be separate components attached to the lower end of the post, which can be replaced after they have been broken or lost due to deformation.

In one embodiment, the post comprises a first damping member to which the other end of the support cable 10 is connected. The first damping member includes a resilient mounting surface for attaching the support cable and a fixed surface for attaching the first damping member to the post, the first damping member damping the impulse to the support cable. The first damping member may be, for example, a spring or a spring support. An impulse can be caused, for example, by an earthquake or explosion. In some cases, the impulse may be due to a load crossing the fairway.

In one embodiment, the support structure includes at least one damping cable connected from the first end to the post. The cover includes at least one other damping member to which one end of the damping wire is connected. The second damping member comprises a resilient mounting surface for attaching the damping wire and a fixed surface for securing the second damping member to the cover, wherein the second damping member is adapted to dampen the impulse exerted on the damping wire. The damping cable fitted to the cover damps the pulses parallel to the support wire. A plurality of damping wires in different directions on the cover can be fitted to the support structure to dampen impulses in different directions.

In one embodiment, the elevated walkway is a track bridge. The wheel bridge is suitable for rail traffic such as local trains, subways or light rail vehicles. In one embodiment, the elevated passageway is a bridge for rubber-wheeled vehicles, for example, a bridge for passenger cars and / or heavy vehicles.

20175945 prh 25 -10- 2017

The raised passage can be made of steel, concrete, reinforced concrete, wood or combinations thereof. The fairway and its supporting structure shall be able to withstand the load and be suitably flexible. In one embodiment, the surface structure of the passage includes charcoal wood. Charcoal wood provides protection against pests and rotting fungi.

The support structure of the elevated passage can be quickly and cheaply laid on the foundation stones. For example, railways can be fitted to the fairway, which provides the possibility of efficient commuting, separate from other vehicles. The passage can be made on the ground level, for example, on foundation stones. At crossings or crossing obstacles, the passage must be increased. In earthquake or crisis areas, local transport rebuilding must be rapid in order to avoid the multiplier effect of logistical problems. If necessary, the proposed support structure can be quickly rebuilt.

The self-contained, gravity-based structure based on counterweights is resilient to various types of earthquake vibrations. The structure recovers from slight fluctuations as the counterweights return to their original positions.

DETAILED DESCRIPTION OF THE INVENTION

Figure 1 shows an example of an embodiment in section. The passage 20 is a depiction of a passageway as a railroad traffic application with a local train 10 traveling along the passageway, shown in broken lines. The passageway is arranged on top of the deck 11 of the passage support structure. For example, the deck 11 may have rails 12.

The cover 11 is supported by at least one post 13. The example of Figure 1 shows two adjacent posts 13. The post 13 is supported by a tensioned support cable 14 attached to the counterweight 15 The first end 16 of the support cable 14 is secured to the counterweight 15 and the other end 17 to a post 13. more support cables in 14 more directions.

20175945 prh 25 -10- 2017

Attached to the cover 11 is a pivoting means 18 including means for receiving a draw of the support cable 14 from the counterweight in the first direction and means for receiving a draw of the support cable 14 from the post in the second direction. In one embodiment, the pivoting means 18 is a pulley, rissa or the like with bearings. In one embodiment, the pivoting means 18 is a fixed structure disposed on the cover 11 - for example, a sliding groove or a similar structure that allows the support cable 14 to slide. Means for tightening or tensioning it, for example a hinged screw, may be provided in connection with the support wire 14. In one embodiment, the support cable 14 is attached directly to the post

13.

The geometry of the counterweight 15 and the support cable 14 defines a limit value for the inclination of the support structure. Other features, such as the weight distribution of the support structure and the elevated fairway, the location and surface area of the support surface, and the permissible load on the fairway, also partially influence the inclination of the support structure. For a raised passage and its supporting structure, a theoretical limit can be calculated, above which the raised passage will be inclined in a controlled manner. The threshold for tilt of the support structure is determinable according to the earthquake scale, Richter scale. When an earthquake exceeds a predetermined magnitude, the channel may be tilted in a controlled manner. When a sufficiently strong earthquake strikes, large-scale destruction is expected despite the computational strengths of the structures. In the event of a collapsed thoroughfare, the steps required to repair it are considerably onerous. Often, the old structure must be completely dismantled from the new one.

Controlled tilt is the desired function of the elevated passage shown herein, whereby the structure collapsed in, for example, earthquakes or similar events that are difficult to predict is easily repaired. Examples of structure repair measures include positioning the cover 11, placing one or more posts 13 or counterweight 15 in their original position, and tensioning the support cable 15. An elevated passage can only tilt partially and return to its original position on its own. In some circumstances, a raised passage may fall to the ground.

20175945 prh 25 -10- 2017

The posts 13 can be made long enough to allow intersecting traffic to fall below the elevated lane. In one embodiment, the passage is arranged to travel elevated, whereby the structure formed by the posts 13 and counterweights 15 acts as a quick-implement foundation arrangement for the passage. The posts 13 may be based on a foundation stone 19. The foundation stones 19 may be block-shaped, standardized supporting structures. The foundation stone 19 may be stone or metal. In one embodiment, the foundation stone 19 is screwed to the ground using a ground screw, whereby the structure is established by a screw foundation. Due to its simple construction, the passage does not immediately require alterations to other infrastructure, such as water or sewerage lines or underground cabling.

Figure 2 is a cross-sectional view of an example of an embodiment in which the top end of the post 13 supports the cover 11. In this embodiment, the cover 11 is provided with a projection 20 around the post 13. The projection 20 limits the movement of the post 13 relative to the cover 11. There may be a plurality of projections 20 around the post 13, or the projection 20 may rotate the upper end of the post 13, positioning the post 13. In this example, the upper end of the post 13 against the cover 11 is cylindrical, whereby the projection 20 forms a sleeve around the upper end of the post 13.

In the example of Figure 2, two top ropes 21 tensioned between the post 13 and the cover 11 secure the upper end of the post to one or more top ropes 21 to balance forces from different directions. The cover cable 21 is secured to the cover 11 by a mounting bracket 22 and the post 13 by a mounting bracket 23. The cover cable 21 or the mounting brackets 22, 23 may include a clamping device, such as a screw.

The joint between the post 13 and the projection 20 may be gravity or secured by ropes. Fig. 3a is a cross-sectional view of an example of an embodiment in which the post 13 and the projection 20 are interconnected by a locking member 30 adapted to be broken by the force exceeding the limit value. The locking member 30 is, for example, a pin or a breakable screw. Figure 3b is a top sectional view of the same example. A circular projection 20 surrounds a circular post 13 where

20175945 prh 25 -10- 2017 locking pieces 30 ensure the post 13 is held in four directions.

Fig. 4 shows an example of an embodiment in which a block-shaped base stone 19 is located beneath the pillar 13. The lower end of the pillar 13 includes a support member 40 which rests against the foundation stone 19. The support member 40 is disposed at least partially around the foundation stone 19. Two flanges are provided on the sides of the support member 40. The first downwardly extending flange 41 rests on the first side of the foundation stone 19. A second downwardly extending flange 42, not shown, rests on one side of the foundation stone. The first flange 41 and the second flange 42 guide the post 13 to be inclined in the direction of the plane formed between the flanges 41,42. The direction of the plane is longitudinal in the direction of block 19.

A locking strap 43 is attached to the foundation stone 19. The locking strap 43 may be a separate component or integrally formed under the base stone 19. In one embodiment, a space is provided for the locking nail 44 extending from the support member 40 against the base stone 19. under. The locking nails 44 limit the inclination of the post 13 in the direction of the plane formed between the flanges 41,42 up to the bending limit of the locking nails 44. In some applications, the locking claws 44 may break, whereby exceeding the bending limit will cause the locking claw 44 to break.

In one embodiment, the support structure is provided with one or more damping members. Figure 5 is a sectional view of an example of an embodiment provided with damping means for two support wires. The first support member 51 is disposed inside the hollow post 13. The post 13 may be a hollow tube, or may include a space or cavity arranged within the damping member. In this example, the post 13 comprises a first damping member 51 to which the other end of the support cable 14 is connected. The first damping member 51 comprises a resilient mounting surface for securing the support cable 14 and a fixed surface for securing the first damping member 51 to the post 14. The flexible mounting surface is, for example, a spring end or a surface attached to the spring end to which the support cable 14 can be secured. First damping member 51

20175945 prh 25 -10- 2017 dampens impulse impedance on support cable 14. The impulse can be caused, for example, by the load on the passage. The first damping member 51 reduces the risk of displacement of the counterweight 15 by, for example, an oscillating impulse at a suitable frequency.

This example also illustrates a second damping member 52. The support structure includes at least one damping cable 53 connected from the first end to the post 13. The second damping member 52 is disposed in a cavity opening under the lid 11, e.g. One end of the damping cable 53 is connected to the second damping member 52. The other damping member

52 comprises a resilient mounting surface for securing the damping cable 53 and a fixed surface for securing the second damping member 52 to the cover. The resilient mounting surface is, for example, a spring end or a surface attached to the end of the spring to which the damping wire 53 can be fastened, whereby the second damping member damps the impulse to the damping wire. The support structure may include only one of the damping members 51, 52. The support structure may include a plurality of other damping members 52 for damping impulses from different directions. The lid 11 can be inserted from the cavity in different directions, for example four directions for the second damping means 52. In one embodiment, a plurality of other damping members 52 are disposed side by side and damping in different directions is effected by directing damping wires 53 to the post 13, for example by means of pulleys from different directions.

In one embodiment, the elevated passage is a track bridge adapted for rail traffic, for example. For example, an elevated passage causes a significant rise or fall in the intersection area, whereby slight friction between the track wheel may cause skidding. Fig. 6 is a sectional view of an exemplary embodiment in which a track 61 is mounted on the cover 11. The track 61 has a track wheel 62 made, for example, of metal. The rim 62 of the rail has a conical flange 64 which is aligned with the groove 63 of the rail 61. The flange 64 wedges into the groove 63 of the track 61, whereby the structure allows for better traction, especially during ascents and descents. In one embodiment, the surface between flange 64 and groove 63 is serrated to improve friction

20175945 prh 25 -10- 2017 with inclined track section. The groove 63 of the track 61 can only be provided on steep sections, whereby the friction of the flange 64 and the groove 63 does not increase the rolling friction of the flat sections.

Fig. 7 illustrates an embodiment in which a rubber wheel 71 is mounted on the same shaft 5 70 as the sprocket 62. The diameter of the rubber wheel 71 is larger than the diameter of the sprocket 62. The track 61 is arranged such that the portion adjacent to the track wheel 62 is higher, so that the vehicle's weight rests on the track 61 while on the track and the rubber wheel 71 on flat ground.

Here, the rubber wheels 71 can be used, for example, for transient transitions between different tracks 61. The end of the rail 61 may be formed such that the rail 61 rises obliquely from the road surface. Thus, as the vehicle travels in the direction of track 61 toward track 61, the distance from track 62 to track 61 decreases until track 61 rests on track 62. Accordingly, weight decreases over rubber wheel 71.

Fig. 8 is a sectional view showing an example of an application of an elevated passage support structure. The post 13 is supported by a tensioned support cable 14 attached to the counterweight 15 In this example, the counterweight 15 is disposed between the posts 13. The support cable 14 is secured to the elevated passageway in the pivoting means 82. The pivoting means 82 may include means for securing the support cable 14 or may lead to a second attachment point of the support cable 14, e.g. The counterweight 15 is adapted to rise from at least one of its edges and allow the elevated passage to self-tilt when the load limit is exceeded. In the example of Fig. 8, the movement of the counterweight 15 is limited by a stop member 80 arranged, for example, by a ground screw 81. The counterweight 15 rests on the stop member 80 when inclined. The stop member 80 may be arranged longitudinally in the direction of the passage.

The figure shows two counterweights 15, the rear of which is represented by dashed lines.

Figure 9 is a cross-sectional view of an example of an elevated passage support structure application. As in the example of Fig. 8, the counterweight 15 is arranged between the posts 13. The counterweight 15 in this example rests on the foundation stone 19. The foundation stone 19 is secured in place by a ground screw 8.

The raised passage can be lightweight and made, for example, of wood. In one embodiment, the surface structure of the lid 11 or the surface structure of the passage

60 is at least partially charred wood. Charcoal wood prevents decay caused by insects and reduces mold decay and decay.

The invention is not limited solely to the above exemplary embodiments, but many modifications are possible within the scope of the inventive idea as defined by the claims.
