Definitions

• the invention relates to a multipurpose road consisting of vertically extending pillars and horizontally extending Trassenab ⁇ cut, which are arranged in rows on the pillars, wherein a plurality of path sections one or more überrap derlying routes or support surfaces for lines form, as well as inside over the entire length
• the multi-purpose road have continuous cavity.
• the object of the invention in the construction of a multipurpose road whose components are also in strong fluctuations in temperature to the least extent possible, the stresses associated with the extension of the route in the longitudinal direction, should be largely neutralized by the geometry of the contact points of the horizontally oriented path sections.
• the glued wood known from the wood glue construction can consist of solid wood, plywood or hardboard webs and always has a layered structure, wherein the usually consisting of the same type of wood layers are combined to form a wooden support of any shape.
• glues for the production of laminated wood all weather-resistant glues, in particular hard-material resins, are suitable, which harden after the addition of hardeners (for example ammonium chloride) at usually higher temperatures.
• hardeners for example ammonium chloride
• glues of acrylate and Pheynolharz- and resorcinol resin base can be used.
• the plates to be assembled together with the laminated wood can be provided with teeth or profiles on the surfaces in contact with one another, which increases the stability against shear forces.
• Laminated wood can be processed in exactly the same way as solid wood, but advantageously has a lower shrinkage or expansion with temperature fluctuations.
• the coefficient of expansion parallel to the fiber is 0.005% for spruce and fir.
• travel distance in the sense of the invention comprises roadways both for rubber-tired vehicles that can be steered independently, and for rail-guided vehicles.
• Rail-guided vehicles include both conventional railway trains as well as magnetic levitation trains and air-cushioned vehicles.
• the core idea of the invention resides in the use of the renewable raw material wood for a multipurpose roadway which consists of trapezoidal roadway sections lined up on pillars. Glued wood is used for the production of the module-like modular track sections and the buttresses. This multi-glued wood is characterized by various, interesting for the construction of tracks and valuable building physical Ei ⁇ properties.
• the temperature- and moisture-dependent shrinkage and expansion of laminated wood is comparatively low.
• the length changes which nevertheless occur within the route sections are compensated in accordance with a further core idea in that the route sections are arranged alternately, wherein the obliquely extending end sides are in contact with the essential part of their surface and in the vertical direction thereon can slide.
• the thermal conductivity of laminated wood is low, so that the cavities provided in the interior of the line sections for the installation of Rohrleitun ⁇ isolated from the outside are. Extreme temperature fluctuations, especially in permafrost areas, can thus be absorbed. This characteristic is particularly important in winter, when the delivery temperatures of oil are above 50 °. Due to the extreme temperature gradients between the outside area and the interior of the pipe, cracking and breaking can occur in the case of steel pipelines without insulation, which therefore have to be isolated in a complex manner. However, track sections made of laminated timber with corresponding cavities for receiving pipelines are load-bearing parts and insulation in one.
• the angle of inclination of the front edges of the trapezoidal route sections is at least 5 ° with respect to a line aligned perpendicular to the base area. It goes without saying that the length compensation between the ausdeh ⁇ nenden or shrinking path sections with less resistance occurs when the inclination angle is greater. Since the edges on the base surface become more susceptible to breakage with the longer longitudinal edge as the front sides become more inclined, the upper limit of the angle of inclination is predetermined by the stability of the laminated wood in this edge region.
• the supporting pillars for receiving the Trassenab ⁇ sections are arranged in one or more rows.
• the double row An ⁇ order of buttresses is recommended for correspondingly wide roadways.
• a plurality of routes are arranged über ⁇ each other and next to each other. It is also conceivable that several routes are only arranged side by side.
• the routes can be positi ⁇ ons above or below the hollow body, which span the multipurpose road. If the driving route is arranged below the cavities carrying the pipelines, the roofing of the driving route, which is expedient in particular in areas with heavy snowfall, advantageously results.
• a snow pad on an upper runway is easy to remove because it can fall down laterally from the road during snow clearing.
• the cavities provided for receiving pipe or supply lines can also be arranged in various ways. To achieve the best possible insulation is proposed to arrange the cavities parallel next to each other. If the route runs above the cavities, the upper side of the cavities is advantageously also insulated.
• this seal is made of a stretchable, permanently elastic material such as rubber or silicone.
• This outer circumferential seal may also be very useful for thermal insulation of the cavities located in the interior of the door sections and the pipe conduits guided therein. In this case, it is conceivable that the individual compartments are also isolated from each other.
• the seal between the end faces of the Trassen ⁇ sections also consist of an acid-resistant round steel or a rounded, U-shaped, acid-resistant spring steel profile, which is applied flat against the bevelled end faces of the compartments and thereby other, additional sealant tion media against any acid damage protects.
• a seal is also present on the end faces of the walls which form individual compartments. This gives the sealing elements a grid-like structure and are inserted in this form between the individual route sections.
• connection of the route sections by additional elements is not absolutely necessary if the coherent construction of the route already creates a stabilization that extends across several route sections.
• the front-side contact surfaces of the route sections each have complementary shaped, eg groove-like, structures which prevent lateral slippage.
• dovetail-shaped grooves or springs can be let into the wood on two adjacent line sections.
• Such grooves and springs can also be formed as separate components made of metal or plastic and embedded in the wood at the Stirnsei ⁇ th the route sections and secured. In particular in seismic areas, such an embodiment may be advantageous.
• steel bolts and / or screw-in sleeves are also possible to use steel bolts and / or screw-in sleeves.
• iron profiles with an angular cross-section bear on the edges of the route sections aligned in the horizontal direction.
• the thigh thickness of the profiles is approx. 20 mm.
• the angle profiles serve to protect the door sections and can additionally stabilize or seal the glued-wood parts joined together with the edge area.
• the pillars are embedded in foundations of concrete. These foundations can be cast at the site or prefabricated. Sand is introduced into the space left between the supporting pillar and the opening in the foundation. By shaking it is ensured that the sand bed is packed as densely as possible and thus optimally stabilizes the buttress. The sand bed also allows optimal damping of vibrations in the lateral direction. The sand bed is sealed off at the top by a seal to protect against weathering and plant seeds.
• This foundation and column construction makes sense for a route that is used only temporarily - for example, on a construction site railway - because it allows easy dismantling and reuse of the columns. Another advantage is the possibility for adjusting the Aus ⁇ direction of the support.
• the supporting pillars are distributed in such a way that they are each arranged below the joint between two adjacent roadway elements.
• wider pillars may be provided therebetween.
• a further, advantageous variant is used for multipurpose roads with particularly often accelerating and decelerating traffic - such as e.g. Mass transport systems with numerous holding stations - and / or vor ⁇ for particularly large fluctuations in the ambient temperature and resulting large fluctuations in length vor ⁇ .
• the pillars can be provided with at least one slot, which is aligned in the supporting direction and senk ⁇ right to the longitudinal axis of the route.
• the pillars gain elasticity and can be moved in the direction of travel of the elevator b.z.w. be pivoted in the direction of elongation or shortening by a small angle.
• the changes in length of each Trassenab ⁇ cut are compensated by slight pivoting of the pillars.
• shock absorbers are inserted between the adjacent route sections.
• a particularly simple variant is the principle of a friction shock absorber.
• a friction plate on one of the support pillars across the slot Side of the slot rigidly attached, for example by screwing. On the other side of the slot, the plate is pressed against the abutment with a defined force.

• This seal should be supplemented by a thermally insulating strip in the joint between two door sections, which in turn is covered on the outside with a permanently elastic material.
• each route section serves as a security element in the case of unusually high changes in length, eg. B. by extremely high temperatures and / or earthquakes or otherwise caused disturbances on ei ⁇ nem or more buttresses.
• the seal would suffer, but the route section could be without Damage be pushed upwards and be reused after Instandet ⁇ tion of the support pillars.
• a further, advantageous embodiment, in particular for routes which have a very small cross section or in which several chambers do not lie above one another for superordinate reasons, but have to be arranged next to one another, can make economic sense in incorporating metal reinforcements into the laminated wood bring to.
• the invention proposes steel bands, they are mounted between the sections of glued timber or to the outer edge.
• a simple variant for fastening is the drilling, punching or burnout of holes through which screws or dowels are guided.
• the invention prefers to weld steel bolts to the steel strip, which engage in corresponding holes in the laminated wood.
• this steel strip can be heated prior to installation. As a result, it expands. When installed in the heated state, it contracts again by cooling; This creates a bias.
• the invention proposes to punch the steel plates over a large area. Through these holes wooden dowels can be performed, which engage in corresponding holes of glue wood panels on both sides of the wood profile. This allows the transfer of forces across the steel profile.
• the steel profiles can be glued to the wood. If the adhesive is permanently elastic, it can also serve as corrosion protection. The dowels then take over the transmission of forces. For the use of the multi-purpose route as a pipeline, the possibility to shut off partial areas makes sense.
• a gate valve is proposed for this purpose, which can be inserted from a slot in a supporting pier 2 into the free cross section of the route (3) by means of a threaded spindle and a nut movable thereon.
• connection of two route sections is a short section with the same cross-section as the long route sections.

• the multi-purpose route is predestined for the construction of supply and / or traffic routes in rough terrain. In these cases, it can be economically advantageous to save the establishment of an additional road next to the track for bringing building materials and construction workers.
