    Description: The invention relates to a construction support with wooden straps and reinforced web, in particular a construction support having two straps of glued laminated timber, between which at least one web of reinforced composite material is mounted.
    Curved full wall girders are among the most widely used construction elements in construction. Because of their usefulness, wooden girders or girders are popular for use with light mounted ceilings, roofs, roof structures, or building envelope grids.
    For less loaded or relatively small carrier lengths usually solid wooden beams or wooden planks (posts) are used. Of great advantage for the beam-wood beams are the uncomplicated production, the favorable mass-strength ratio, ease of use and the possibility of subsequent changes to the site. Wood is also a renewable material, and the waste produced in the manufacture of beams is also a suitable material from which a composite can be made. On the other hand, the drawbacks mentioned are the lower modulus of elasticity and the flammability compared to other materials made of other materials.
    In order to achieve larger spans of building structures, or otherwise in construction are made of wood or wood products existing solid wall support with an I or H section used. Structurally, these are wooden harnesses made predominantly of dried planed spruce lumber and glued to a web of hardwood fiberboard, which is mostly chipboard from wood chips. The plate web is glued with a wedge connection in milled grooves of the upper and lower flange. The straps are usually extended by means of tine connections. Such carriers are also referred to as I-OSB carriers. In contrast to traditional solid wooden beams, l-OSB wood beams are more dimensionally stable and lighter. In addition, they are able to transmit large loads even with large design lengths. The elements are as easy to work with as beam supports and are easy to handle. Openings can be drilled to a limited extent in the dock to carry installations perpendicular to the girders. A disadvantage of these carriers is the limited strength of the fibreboard web. Long-term loads or load or moisture can reduce this strength.
    As a further variant of the commonly used, made on the basis of wood or wood materials carrier formwork support are to be considered. These are carriers for system shuttering (such as DOKA and PERI). The structural arrangement is the same as in the I-OSB carriers. The wooden straps are made of high quality, mechanically sorted wooden profiles and the bridge consists of a special press plate or a three-layer glued profile (DOKA H20, PERI VT). The ends of the beams are studded and bevelled, because of the durability to be used repeatedly many times. The high load-bearing capacity is advantageous, while the other properties are similar to those of the I-OSB girders. The disadvantage is the high purchase price.
    It was also a special variant of the formwork girder with truss-like web of glued profiles and wooden belts - the carrier PERI GT 24 - developed. This carrier has a greater static height and thus a greater carrying capacity at a lower dead weight. The other properties are similar to other formwork beams.
    Last but not least is still a combined variant of steel-wood beams, to mention of so-called. POSI-JOIST straps whose straps are made of wood, and their webs of steel struts (framework of steel sheets). The components of the Posi-Joist straps are wooden straps and two rows of steel struts Posi-Strut. The combination of the lightness of the wood and the strength of the steel makes it possible to bridge a much wider span than is possible with other timber beams. The wooden beams or wooden girders are indeed in the
    Practice much needed, but do not reach the high load capacity of the steel rolling profiles.
    The invention relates essentially to the construction of a curved solid wall support with wooden straps, which guarantees in cooperation with the reinforced composite web optimal behavior in the cross section of the I-beam and a high load capacity of the element, which is higher than the carrying capacity of conventional Wood-based supports.
    Accordingly, the invention generally provides a construction support with at least two spaced, prismatic, made of glued hard laminated plywood straps before, which are connected together at least by a, positioned perpendicular to the longitudinal axis of the straps web. The bridge is attached at both ends in the straps. The attachment is made with a conical extension and an adhesive connection, where inside the bridge long been the straps reinforcing steel laid.
    In particular, the construction carrier according to the invention is characterized in that it is formed by at least two prismatic straps arranged at a distance from each other, which holds together at least one, perpendicular to the longitudinal axis of the straps extending web of composite material, at the two ends in the Straps is secured by a conical extension and by an adhesive connection, wherein the web steel reinforcements, which are installed in the web in the longitudinal direction of the straps.
    According to a favorable embodiment, a belt consists of two or more identical parts, which are connected to each other, either by a direct adhesive bond or by an arcuate, located in the middle part of the web level adhesive bond. The belt parts have an identical orientation of the wood slats.
    However, the belt can also consist of a single part.
    The web can be formed by two identical parts, which are interconnected by a flat, provided perpendicular to the longitudinal axes of the straps adhesive bond. The orientation of the wooden lamellae of the belt component is identical. According to another favorable embodiment, the belt may consist of three or more parts, which are joined together either by direct or by arcuate adhesive joints, wherein the straps are held together by two identical web portions which surround a belt middle portion from two opposite sides. The orientation of the wood slats of the web portion spanned by the web parts is identical or may be different than the two adjacent belt parts.
    Preferably, the web is made of a composite material mixture of polyester resin and woodchip filling. Wood chips are obtained by processing waste from the production of wood products. Also, the web can be made from a composite material composition of which, in terms of the total mass of the composite mixture, is either 30-70% wood and 30-70% polyvinyl chloride or 30-70% wood and 30-70% polyethylene with a high mass Dense or 30-70% wood and 30-70% polypropylene.
    In each web, or in each web component at least one the web in the longitudinal direction to the belt continuous end reinforcement made of steel and at least one steel reinforcement is installed at each end, the web in an oblong direction to the straps, diagonal alternately from one edge goes through reinforcement to the next. The elongated edge reinforcements of the web are connected by welds with the reinforcement, which passes through the bridge diagonally alternately from one end reinforcement to the next. Preferably, the reinforcements are made of reinforcing steel of class B500B or B420B. These reinforcements increase the static load carrying capacity of the structural beam with the composite web.
    The main advantage of the present construction support is its high carrying capacity while maintaining a low mass of the element.
    The invention will be explained below with reference to Ausfüh insurance examples shown in the drawing even further. FIG. 1 shows a side view of a construction carrier in the basic version according to FIG
    Fig. 5, with identical orientation of the slats of the wooden belt parts; Fig. 2a shows a cross section according to the line A-A in Figure 1 by the carrier, with a single web and with a direct adhesive connection of the straps ..; 2b shows a corresponding cross section A-A through the carrier, with a single
    Bridge, but with a curved adhesive bond of the straps; 3a shows a cross section A-A through the carrier, but with a two-part, glued th web and with a direct adhesive bond of the straps. Fig. 3b shows a cross section A-A through the carrier, with a two-part, glued
    Bridge, but with a curved adhesive bond of the straps; 4a shows a cross-section A-A through a carrier which has at least three belt parts with a direct adhesive connection and a two-part web; Fig. 4b shows a cross-section A-A through a carrier having (at least) three belt parts with a curved adhesive connection and a two-part web; and Fig. 5 is a partial axonometric view of a structural beam according to the invention.

The parts of the belt 1 have an identical orientation of the wood slats. The straps 1 are shown in Fig. 3 and 4 connected by two webs 2 together. The webs 2 consist of one piece and are made of a polyester resin composite material with wood chips filling. They connect the straps 1 at the locations of the adhesive connections 3a, 3b. The webs 2 are reinforced at both ends in a conical enlargement. The reinforcement is effected by guided in the longitudinal direction of the straps 1 end reinforcements 4 and by a central reinforcement 5, which extends diagonally alternately from one end reinforcement 4 to the next (Fig. 2). The final reinforcements 4 of the web 2 and the web 2 diagonally alternately from a final reinforcement 4 to the next continuous reinforcement 5 are held together by welds 6. Reinforcements are made of grade B500B or B420B rebar.
    According to another embodiment, the construction carrier has two prismatic straps 1 arranged at a distance from one another, whose mutual distance 1 is 0.4 m outside and whose height is 0.2 m. They are made of glued hardwood, glued laminated timber, consist of six parts which are joined together by a direct adhesive joint 3a (FIG. 4a) or by an arcuate adhesive bond 3b (FIG. 4b). The mutual connection of the straps 1 is effected by two pairs of identical parts of the web 2. The web parts include on two opposite sides a central part of the straps 1 a. The webs of the spanned by the web parts 2 belt part 1 are aligned differently than those of the two adjacent parts of the belt 1. The webs 2 are made of a composite material whose components in terms of mass in relation to the total mass of the composite material 30% wood and 70% polyvinyl chloride. Each web part 2 is reinforced at both ends in a conical enlargement. Reinforcement is effected by the final reinforcements 4 of reinforcing steel of class B420B guided in the longitudinal direction of the straps 1 and by a central reinforcement 5, which runs diagonally alternately from one end reinforcement 4 to the next (FIG. 2).
    The final reinforcements 4 of the web 2 and the web 2 diagonally alternately from a final reinforcement 4 to the next continuous reinforcement 5 are held together by welds 6 (Fig. 1).
