Definitions

the present invention relates to a structural element according to the preamble of claim 1.
facade scaffold Particularly in building construction plate-shaped construction elements are used as part of the facade scaffold. It is distinguished between several use classes, which u.a. describe the dimension (width of the plate), the payload and the purpose. Since a façade scaffold is a temporary device, these scaffoldings are usually modular in design, i. Virtually any scaffolding constructions can be created with a few, uniformly constructed elements (side members, cross members and plates).
the plate-shaped construction elements usually have a length of 250 cm and a width between 60 cm and 90 cm. They are usually used for all usage classes. They are predominantly stressed on bending, whereby in addition also individual, concentrated load cases must be covered.
panels are made of wood, a composite of wood with aluminum, aluminum or steel.
all of these materials have specific disadvantages.
Hybrid plates in terms of weight no major differences, but are insensitive to water absorption. However, in addition to the risk of failure of the welds, such plates have very poor fatigue properties, which also results in only a limited service life.
the plates currently available on the market also have a low slip resistance, which adversely affects safety.
the plates were made of plastic, resulting in lower weights and better environmental resistance over conventional plates.
the plastics generally have an unfavorable modulus of elasticity, so that the required properties either could not be achieved or very thick plates resulted.
the object of the present invention was now to provide such a plate-shaped construction element in one piece of plastic, which is able to absorb the required bending loads with the lowest possible weight.
the element By forming the element with a flat pressure belt and lateral tension straps high bending stiffness can be achieved with low wall thickness, which finally leads advantageously to a low weight of the element with small dimensions.
the formation of the element with arranged below the base plate transverse ribs allows the construction of a base plate with a relatively small thickness.
corrugations are formed in the surface, which allow the construction of a base plate with relatively small thickness leaving flat transverse regions, which are reinforced by the arranged below the base plate transverse ribs.
plastic preferably fiber-reinforced plastic
the beads are advantageously only formed so deep that the stiffening effect is sufficient, but no disadvantages arise in terms of serviceability of the structural element. This is understood in particular the accessibility of the construction element, which should not be affected by too deep or upwardly projecting elements.
CFRP elements such as CFRP tapes
the tensile load of individual areas of the construction element can be specifically increased, without affecting the dimensions or the weight significantly influenced, ie enlarged.
These reinforcements are preferably applied in the region of the maximum tensile loads, ie on the undersides of the transverse ribs and the lower regions of the two lateral flanks.
connection elements may be attached to the transverse sides of the structural element, according to the intended use and training of the corresponding connecting members, for example, the scaffolding construction.
connection elements Preferably in the form of hook-shaped elements, which are connected, for example, with the flanks of the structural element and protrude in the longitudinal direction thereof.
FIG. 1 is the supervision and in FIG. 2 the longitudinal section of a design element designed according to the invention shown.
the substantially 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 each other at regular intervals over the entire width of the base plate 1. Between the longitudinal direction of the base plate 1 spaced groups of beads 2 transverse regions 3 are formed free of beads or other elevations or depressions.
flanks 5 show outside projecting connecting elements, here in the form of downwardly open profile struts 6.
profile struts 6 can now be hung, for example in cross struts of scaffolding structures (not shown) resp. be hung up.
these profile struts 6 can be arranged cross-over, and thus, for example, connected together with a cross member.
transverse ribs 7 are 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 via resp. are connected with these. This prevents bulging of the flank surfaces 4 under load of the base plate 1.
This design of the construction element can be made of relatively thin material, a rigid plate-shaped element.
the base plate 1 with the beads 2 serves as a pressure belt and the two flank surfaces 4 as a tension belt of the element.
such a construction element is made of plastic, which on the one hand leads to an advantageous weather resistance and on the other hand has a high rigidity with low weight due to the shaping according to the invention. This makes it possible to handle such construction elements particularly well and are particularly suitable for use as support plates for scaffolding.
FIG. 3 is shown in more detail a longitudinal section of the structural element in the region of the transverse ribs 7. From the illustration, the formation of the remaining transverse region 3 can be seen, which extends over the entire width of the plate 1. Below this transverse region 3, the transverse rib 7 is arranged, which is on the one hand directly connected to the underside of the base plate 1 and is connected at its two ends directly to the flank surface 4.
the transverse rib 7 has a porous core 8, for example with a honeycomb structure.
This core may be enveloped by a cover layer 9, preferably made of plastic.
This layer can be simple or multiple.
a CFK reinforcement 10 may be applied, advantageously on the underside of the transverse rib 7, as in FIG FIG. 3 shown.
the transverse rib 7 has a trapezoidal cross-section, which, on the one hand, ensures optimum force transmission and reception and, on the other hand, is also simple and therefore inexpensive to produce.
flank surfaces 4 can also have CFRP reinforcements, in particular in the lower region, for increasing the rigidity and tensile strength.
CFRP reinforcements in particular in the lower region, for increasing the rigidity and tensile strength.
FIG. 4 is still a cross section through an inventively designed construction element shown, from which the formation of the beads 2 is particularly well.
the flank surfaces 4 in the lower region an additional kink, in the present case directed to the outside, have.
the kink resp. Beulsteifmaschine the flank surfaces significantly increased, resulting in greater stability and rigidity of the structural element. Due to the training with kink, the scaffolding floors can continue to be easily stacked on each other.
the outer, lower flank area ensures on the one hand for a Lüarretmaschine in the transverse direction and on the other hand allows the stackability.
the construction element may be formed without the beads 2, with a substantially flat surface 1.
the surface can now be preferably equipped with a slip-resistant coating, which significantly increases the safety of the structural element, especially in scaffolding.
FIG. 5 the longitudinal section through such a structural element shown, in which the surface 1 is formed substantially flat and below the transverse ribs 7 are arranged at regular intervals from each other.
the formation of the connecting element in the form of a hook 11 is shown schematically here.
This hook 11 is advantageous Made of metal and connected to the flank surface 4.
any connection element which is adapted to be connected to the corresponding support structure.
the specific connection systems of different scaffolding systems attached to the end face of the element, respectively. be incorporated into it.
the inventive combination of longitudinal and transverse elements, a simple, rigid and lightweight construction element is provided, which is advantageously produced in fiber-reinforced plastic. These materials are easy to process and show particularly good weathering and corrosion properties with high stability and light weight.
flooring elements for facade scaffolding such structural elements are characterized by their advantageous properties in terms of stackability and transport, as well as by rapid handling. Further areas of application are therefore the exhibition construction, the stage construction or the use in the facade area of buildings.
