Description

ref. P 2020 NL. 008 TITLE: Bridge span The subject of the invention is a bridge span of a footbridge or road bridge, made partly of composite materials.
Known are bridges and footbridges made of composite components by infusion or finished composite parts, which are built like steel bridges, but steel is substituted with composites. However, due to deep-rooted traditions in bridge construction and the relatively high material costs for the construction of bridges and footbridges, composites are not widely used.
From the patent description PL 200595, a footbridge is known, consisting of at least one composite segment formed of detachable and / or inseparably connected bearing sheath with a cross-section similar to the letter "U", In its lower part provided with a bracing surface and with bracing side elements, where the balustrade railing is the main load-bearing element and constitutes the upper girder belt.
From the Polish patent specification 231211 a road bridge span is known, consisting of main transverse support girders and a platform slab, characterized by having at least two main girders with a box-like, open cross-section, made of fibre- reinforced plastic (FRPP) composite materials, which are braced on ends with transverse support members and are permanently joined to the platform slab, whereby the transverse support members and the platform slab are made of lightweight concrete reinforced with composite bars and stirrups made of FRP composite.
From the US patent US4079476 a structure of a footbridge made of FRP composite materials is known. The bridge span consists of one main girder with a U- shaped cross-section, whose webs are also a balustrade, the upper belt is shaped as a handrail, while the lower belt is also a footbridge. The girder is reinforced along the length with external ribs that ensure the stability of the girder shape and its torsional rigidity. All girder elements are made of FRP composite, made of fabrics, mats and glass rovings, arranged in a polymer resin matrix.
The purpose of the invention is to use ready-made composite elements for the construction of the bridge span as structural and load-bearing elements that could successfully compete with traditional solutions, also with regard to the total construction and operating costs. The purpose of the invention is alse constructing a bridge span with excellent corrosion resistance, high durability and low weight.
— 2 According to the invention, the bridge span comprising at least one girder and platform is characterized in that at least one wind turbine rotor blade constituting the girder is fitted with ribs and the platform is attached to the ribs.
Preferably one girder consists of two wind turbine rotor blades connected to each other by means of flanges.
Preferably, the ribs are provided with a cut-out of a shape matching the shape of the outer surface of the wind turbine rotor blade.
As a variant, the bridge span is equipped with truss ribs made of steel profiles of a shape matching the shape of the outer surface of the wind turbine rotor blade.
Preferably the bridge span is equipped with at least two supports attached to the outer ribs or outer ends of the wind turbine rotor blade.
As a variant, the ribs are connected to at least one transverse crossbar with an axis parallel to the blade axis.
As a variant, a part of the platform is made as a step constituting a bench, connected to the blade.
Wind turbine blades withdrawn from use after 25-30 years retain their full strength and properties. These properties allow them to be used for the construction of footbridges and bridges. The essence of the invention consists in the use of a wind turbine rotor blade as a load-bearing structural element of a bridge, i.e. as a girder. Such use of blades will allow creating completely new shapes and forms of bridge spans in comparison to those currently available, due to the ease of implementation and closed load-bearing structure, which allows to use the remaining space as needed. The blades are made of composite materials and their strength is comparable to traditional materials such as reinforced concrete or steel, while the strength of wood is significantly exceeded. Composite materials have low specific gravity of about one quarter that of steel. Thanks to this, the structure of the composite bridge is at least half lighter compared to concrete or steel. The ribs attached to the blades provide additional stability to the girder shape and its torsional 20 strength.
The bridge spans according to the invention allow the construction of bath footbridges and road bridges, over roadways or rivers.
The invention is illustrated in the figure, in which fig. 1a shows a side view of a span of a footbridge, equipped with one girder consisting of one wind turbine rotor blade with ribs attached to the lower outer surface of the blade; fig. 1b shows a bottom view of a span of a footbridge, equipped with one girder consisting of one wind turbine rotor blade with ribs attached to the lower outer surface of the blade;
