Definitions

  • the invention relates to a support and connection profile made of light metal for a self-supporting framework, in particular for lightweight halls and large tent structures that has at least one running in the longitudinal direction of the profile body reinforcing insert of a fiber composite material. Furthermore, the invention relates to a method for producing a fiber-reinforced metal profile.
  • the invention relates to a support and connection profile made of light metal for a self-supporting framework, in particular for lightweight buildings and large tent structures, which has at least one running in the longitudinal direction of the profile body reinforcing insert of a fiber composite material.
  • Such profiles are from the WO 01/46536 known. These known support and connection profiles have the reinforcing layers in recesses of the outer surface of the profile body, wherein the reinforcing layers are exposed to the inside or outside in areas and are not completely enclosed. Depending on the type of connection between the profile body and the reinforcing insert, forces of different magnitude can be transmitted from the profile body to the reinforcing layers.
  • This object is achieved with the present invention essentially in that in a perpendicular to the longitudinal direction of the profile body cross-section in the profile body is formed at least one closed chamber in which at least one reinforcing insert material, form and / or non-positively fixed.
  • a closed chamber surrounding the connection profile offers the advantage that the forces can be introduced or absorbed over the entire reinforcement insert.
  • the reinforcing insert is effectively protected in the closed chamber in the profile body from mechanical or other damage.
  • the optimal utilization of the physical properties of the reinforcing insert taking into account the loads occurring, also enables a reduction of the dimensioning of the profiled body material. The reason for this is that the forces, in particular the bending moments and tensile and compressive forces, as they occur, for example, when exposed to wind, are primarily absorbed by the reinforcing insert and need not be borne by the profile body.
  • a closed chamber can be formed by a wall section of the profile body as well as by a cover or the like.
  • the cover can be detachably connected to the profile body by means of e.g. Clamping, latching snap, or plug connections be connected.
  • the at least one closed chamber is formed integrally with the profile body.
  • the at least one closed chamber is designed such that its lumen in a direction perpendicular to the longitudinal direction of the professional body cross section is greater than the reinforcing insert.
  • a gap which can be used for bonding the fiber reinforcement to the profile remains between the inner surface of the chamber and the outer surface of the lamellar fiber reinforcement, for example.
  • An all-round surface bonding, with the exception of the front sides, is very helpful for a good connection of the fiber reinforcement to the metal profile.
  • the fiber reinforcement can only be effectively used to absorb tensile or compressive forces if such a good bond with the metal profile is present.
  • At least one guide and / or spacer element is provided on the inside of the at least one closed chamber and / or on the Outside of the reinforcing insert.
  • a spacing and / or guide element can preferably be designed as a rib extending in the longitudinal direction of the profile body.
  • tents or hall constructions stipulate that all building materials in accordance with DIN 4102 Part 1 must be at least flame retardant. Only for roofs that are higher than 2.30 m above accessible areas, may normal inflammable building materials in accordance with DIN 4102 Part 1 be used. In other countries, tents or halls are treated in part as other structures, ie they are also subject to the Fire protection regulations for such structures. These provide in part that the buildings have to resist fire for 30 or 60 minutes. Aluminum and steel can not do this alone, but deform or start to melt. By adding appropriate chemicals such as aluminum trihydrate, bromine or the like, fire classes can be achieved to meet any national fire safety regulations.
  • support and connection profiles according to the invention may have a great length compared to their other dimensions.
  • the length of the metal profiles for example, by a factor of 20, but in particular by a factor of 50 to about a factor of 150, be greater than its width and / or height.
  • the total length of the fiber-reinforced metal profiles can be over 10 meters, depending on the purpose.
  • grooves are preferably provided in the support and connection profile according to the invention.
  • the profile body is approximately rectangular in a perpendicular to the longitudinal direction of the profile body cross-section, the height of which is greater than its width, and wherein in at least two corners each have at least one groove for receiving a welt or the like.
  • the arrangement of one groove in each of the four corners is particularly preferred. In principle, however, it is also possible to provide such grooves or other suitable fastening devices at other positions of the profile body.
  • the profile body as a post, roof bolt, gable support, gable cross-beam, purlin, cloth holder, post shoe, gable support with ground attachment, stem-bolt connection in eaves, ridge connection between individual roof bars, connection between gable supports and roof bars, cross dressing for stiffening between posts and between roof bars or the like. Scaffolding part may be formed.
  • the self-supporting framework can be constructed entirely of profiles of the type according to the invention.
  • the object underlying the invention is further achieved by a method for producing a fiber-reinforced metal profile with the following method steps: First, a profile body is provided, in which in a direction perpendicular to the longitudinal direction of the profile body cross-section at least one closed chamber is formed. Thereafter, an adhesive is filled in this at least one closed chamber. Finally, a reinforcing insert containing glass fibers and / or carbon fibers is introduced together with adhesive into the closed chamber which has already been filled at least partially with adhesive.
  • This method according to the invention has the effect that - with the exception of the front side - all-round good bonding between the closed chamber and the reinforcing insert is achieved.
  • Pre-filling the closed chamber with the adhesive prevents the adhesive film between the reinforcing insert and the chamber from tearing off when the reinforcing insert and adhesive are introduced together. Rather, the adhesive flows around the reinforcing insert during insertion into the chamber.
  • both the metal profile and the reinforcing insert during assembly are aligned substantially horizontally. This simplifies handling and also reduces the risk of trapped air, which could occur with a vertical orientation of the metal profile.
  • the viscosity of the adhesive is between about 1,000 mPas and about 3,500 mPas.
  • a particularly preferred range is about 2,100 mPas to about 2,500 mPas (measured in each case at 25 ° C).
  • Bonding film with the layer thickness of at least 0.3 mm, in particular between about 0.4 mm and about 2.5 mm, is formed. This can be facilitated in particular by the use of the above-described guide and / or spacer elements.
  • the profile body according to the invention has an approximately rectangular cross-section, wherein its height is greater than its width.
  • a closed chamber is provided in the vicinity of the upper side and in the vicinity of the underside of the profile body, adhesive and a reinforcing insert being introduced into each of these chambers by the method according to the invention.
  • the profile has a substantially rectangular shape and has at the respective corners outwardly open grooves 3, in which fastening and / or not shown Functional elements, for example via keder fastenable walls, can be attached.
  • a chamber 4 is formed in the interior of the profile body 2 between two grooves 3, which extends in a direction perpendicular to the longitudinal direction of the profile body cross section and having a reinforcing insert 5.
  • the chambers 4 have in the illustrated embodiment an at least substantially rectangular cross-section, wherein the width of the chambers 4, ie the extension between the grooves 3, is greater than the thickness of the chambers. This embodiment allows a particularly high bending strength of the profile. 1
  • the reinforcing insert 5 is preferably by unidirectional fibers, in particular carbon and / or glass, and a surrounding these Matrix 6 formed.
  • the reinforcing insert is fixed in the chamber 4 by the fibers are potted or glued to the matrix in the chamber.
  • Fig. 2 Another variant for fixing the reinforcing insert 5 in the chamber 4 is in Fig. 2 shown. Also shown here is the support and connection profile 1, consisting of the support and connection profile body 2 shown in cross-section and the grooves 3 at the corners of the profile body 2.
  • the support and connection profile 1 consisting of the support and connection profile body 2 shown in cross-section and the grooves 3 at the corners of the profile body 2.
  • Fig. 1 has the in Fig. 2 Profiled body 2 shown a substantially located in the middle of the profile cross section web 7, which connects the two long sides of the profile body 2 together.
  • the chamber 4 is formed, which receives the reinforcing insert 5.
  • the reinforcing insert 5 is fixed to the web 7 via a rivet connection 8.
  • the bridge can be varied depending on the application. So it is also possible that the bridge connects the two short sides of the profile body or diagonally the corners together.
  • the profile body 2 may have a plurality of webs and the webs in turn a plurality of chambers.
  • the chamber 4 does not have as in the FIGS. 1 and 2 may be formed integrally with the profile body 2, but may be formed from a number of elements, such as in a chamber which is at least partially formed by a wall portion of the profile body and by a separate cover.
  • Fig. 3 Such a form of embodiment of a profile is in Fig. 3 shown, which has a similar structure to that in Fig. 1 Having shown support and connection profile 1.
  • the chambers 4 are each formed on the one hand by a wall portion 9, which is embedded in the profile body 2 in this embodiment, as well as by a cover 10.
  • the reinforcing insert 5 In this chamber 4 is the reinforcing insert 5, by means of eg pouring, gluing, screws, rivets or is fixed by the cover 10 itself.
  • the cover 10 is connected to the profile body 2 by means of releasable connections 11 such as clamping, latching, snap, - or plug connections.
