Definitions
- the present invention relates to a construction element according to the preamble of claim 1.
- Construction elements used as part of the facade scaffolding are used as part of the facade scaffolding. A distinction is made between several use classes, which include circumscribe the dimension (width of the plate), the payload and the intended purpose. Since a facade scaffold is a temporary one
- these scaffolds are usually built on a modular principle, i.e. With just a few, uniformly constructed elements (side members, cross members and plates), practically any scaffold construction can be created.
- the plate-shaped construction elements usually have a length of 250 cm and a width between 60 cm and 90 cm. They are generally used for all types of use. They are mainly subjected to bending, although individual, concentrated load cases must also be covered.
- Hybrid panels made of wood and aluminum have reduced their own weight compared to pure wooden panels, but the disadvantages with regard to water absorption are still present.
- the risk of failure due to water absorption komrru. here further a possible failure of the welds of the aluminum frames.
- the plates were made of fiber-reinforced plastic, which has led to lower weights and better environmental resistance compared to conventional plates.
- the plastics generally have an unfavorable modulus of elasticity, so that the required properties either could not be achieved or very thick sheets resulted.
- the object of the present invention was to provide such a plate-shaped construction element which can absorb the required bending loads with the lowest possible weight.
- the element with a flat pressure belt and side tension belts By designing the element with a flat pressure belt and side tension belts, a high degree of flexural rigidity can be achieved with a low wall thickness, which ultimately leads to a low weight of the element with small dimensions.
- the formation of the element with transverse ribs arranged below the base plate allows the construction of a base plate with a relatively small thickness.
- beads are formed in the surface which, while leaving flat transverse regions which are reinforced by the transverse ribs arranged below the base plate, allow the construction of a base plate with a relatively small thickness. This means that a stiffness that meets the requirements is achieved even when using plastic, preferably fiber-reinforced plastic.
- the beads are advantageously only deep enough that the stiffening effect is sufficient, but there are no disadvantages with regard to the usability of the construction element. This means in particular the accessibility of the construction element, which should not be impaired by elements that are too deep or protrude upwards.
- CFRP elements such as CFRP tapes
- CFRP tapes allows the tensile load of individual areas of the construction element to be increased in a targeted manner without the dimensions or weight being significantly affected, i.e. be enlarged.
- These reinforcements are preferably applied in the area of the maximum tensile loads, i.e. on the undersides of the transverse ribs and the lower areas of the two outer flanks.
- connecting elements as profile struts which are open at the bottom and have a rounded cross section makes it easy to connect the structural elements to one another and, for example, to cross struts of scaffold structures.
- any other can Connecting elements may be attached to the transverse sides of the structural element, in accordance with the intended use and design of the corresponding connecting elements, for example the scaffold structure.
- Figure 1 is a schematic plan view of a construction element according to the invention with beads formed in the surface. 2 shows the longitudinal section through the construction element according to FIG. 1;
- Fig. 3 shows the longitudinal section through the
- FIG. 1 Construction element according to Figure 1 in the region of a transverse rib;
- Figure 4 shows the cross section of the construction element according to Figure 1;
- FIG 5 shows the longitudinal section through an alternative construction element according to the invention with hook-shaped connecting elements.
- the essentially rectangular upper side of the base plate 1 here preferably has a large number of beads 2, which advantageously all have the same length and width.
- the beads 2 are each arranged in groups parallel to one another at regular intervals over the entire width of the base plate 1. Between the groups of beads 2 spaced apart from one another in the longitudinal direction of the base plate 1, transverse regions 3 are formed free of beads or other elevations or depressions.
- Flank surfaces 4 protrude downward from the base plate 1 along the two long sides.
- the flank surfaces 4 are advantageously rounded at the ends, as can be seen in particular from FIG.
- Flanks 5 which are angled downward and which have a smaller height than the flank surfaces 4 also protrude on the transverse sides of the base plate 1.
- the flanks 5 have connecting elements projecting outwards, here in the form of profile struts 6 which are open at the bottom.
- Cross struts of scaffold structures are attached or. be put on. Of structural elements that follow one another in the longitudinal direction, these profile struts 6 can be arranged so as to overlap one another, and can thus be connected together, for example, to a cross strut.
- transverse ribs 7 are now formed, which extend over the entire width of the base plate 1.
- the ends of these transverse ribs 7 go directly into the flank surfaces 4 respectively. are connected to them. Bulging of the flank surfaces 4 under load on the base plate 1 is thus avoided.
- This configuration of the construction element enables a stiff plate-shaped element to be created from relatively thin material.
- the base plate 1 with the beads 2 serves as a compression belt and the two flank surface 4 as a tension belt of the element.
- Such a construction element can advantageously be made of plastic, which on the one hand leads to advantageous weather resistance and on the other hand has high rigidity with low weight due to the shape according to the invention.
- Such construction elements can thus be handled particularly well and are particularly suitable for use as support plates for scaffolding.
- FIG. 7 A longitudinal section of the construction element in the region of the transverse ribs 7 is shown in more detail in FIG. The illustration shows the formation of the remaining transverse region 3, which extends over the entire width of the plate 1.
- the transverse rib 7 is arranged below this transverse region 3, which is connected on the one hand directly to the underside of the base plate 1 and is connected at both ends directly to the flank surface 4.
- the transverse rib 7 advantageously has a porous core 8, for example with a honeycomb structure.
- This core can be encased by a cover layer 9, preferably made of Plastic. This layer can be carried out one or more times.
- a CFRP reinforcement 10 can preferably be applied, advantageously on the underside of the transverse rib 7, as shown in FIG. 3. The tensile region of the transverse rib 7 is thus reinforced without the cross section being enlarged or the weight being increased significantly.
- the transverse rib 7 advantageously has a trapezoidal cross section, which on the one hand ensures optimum power transmission and absorption and on the other hand is simple and therefore inexpensive to manufacture.
- flank surfaces can also have 4 CFRP reinforcements, in particular in the lower area, to increase the rigidity and tensile strength. This allows the maximum permissible load and payload of the construction element to be set according to the requirements.
- FIG. 4 also shows a cross section through a construction element designed according to the invention, from which the formation of the beads 2 emerges particularly well.
- the flank surfaces 4 can have an additional kink in the lower region, in the present case directed towards the outside. With this kink, the kink or
- the construction element can also be formed without the beads 2, with an essentially flat surface 1.
- the surface can now preferably be equipped with an anti-slip covering, which significantly increases the safety of the construction element, especially in scaffolding.
- FIG. 5 The longitudinal section through such a construction element is shown in FIG. 5, in which the surface 1 is essentially planar and below which the transverse ribs 7 are arranged at regular intervals from one another. Furthermore, the connection element in the form of a hook 11 is shown schematically here This hook 11 is advantageously made of metal and connected to the flank surface 4.
- any connecting element that is suitable for being connected to the corresponding supporting structure can be arranged on this end surface of the construction element.
- the combination of longitudinal and transverse elements according to the invention provides a simple, rigid and light structural element which can advantageously be produced in fiber-reinforced plastic. These materials are easy to process and show particularly good weather and corrosion properties with high stability and light weight.
- Covering elements for facade scaffolding are characterized by such advantageous construction elements in terms of stackability and transport, as well as quick handling. Other areas of application are therefore also exhibition construction, stage construction or use in the facade area of high-rise buildings.
