Definitions

  • the invention relates to a connection of at least two roof trusses with a plurality of substantially horizontal purlins, which are each formed at their two ends with downward-facing support hooks which engage with the hanging straps fastened with the roof trusses and are secured against unintentional lifting out of the vehicle by means of a securing device
  • Hanging brackets are secured, the purlin having in its end regions a bracket joint extending transversely to the purlin longitudinal extension and parallel to the purlin floor at a predetermined distance, which is provided with pivotable locking brackets, in particular for the construction of tent scaffolding.
  • a securing of the connecting purlins against undesired lifting out of the hanging tabs connected to the binder is generally achieved in that at the lower end of the leg of the carrying hook facing the binder, below the tab, there is a hole for receiving an engaging in the binder Locking pin is provided.
  • a disadvantage of this secure locking is the need to insert or remove the pin at the respective height.
  • connection between the purlins is secured in a supporting structure for a tent in that a securing bracket is provided on at least one end of each purlin, which is pivotally connected to the purlin about an axis running transversely to the longitudinal axis of the purlin and reaches under the hanging tab.
  • a disadvantage of this design is that the locking mechanism does not engage in the hanging tab, but extends over it from the outside. This means that at a, e.g. B. always possible assembly failure, conditional, resulting inclined position of the vertical axis of the girder profile, the risk of lifting the attack bar is given.
  • Fixing the hook position to the truss can in no way be ensured by such a hold-up bar.
  • connection according to the type described at the outset, which prevents an independent removal of the anti-excavation device even when the binder is tilted about its vertical axis, and which, when the anti-excavation device is engaged, also reduces the usual play between the Hook and the binder side walls allows.
  • the locking bracket with its end facing away from the binder is designed to be heavier than the bracket end pointing to the hanging tab and is curved such that in the locked position the bracket end runs approximately parallel to the hook at a zero-leading distance and the subsequent angling of the locking bracket rests against the inner edge of the suspension bracket, and that the angle between the bracket end and the subsequent bend is formed by or over 90 °, and the further bend leading to the bracket joint is designed to rise, while the overweight end, relative to the purlin plane, follows is angled below, and the end region is designed as a fork stop for a purlin lifting fork.
  • the positive engagement of the locking bracket in the hook-in tab connected to the purlin provides both a safe, simple locking and a reduction in the play of the purlin in its longitudinal extent between the binders.
  • the fork itself is formed by a U-profile that is connected to the bottom of the purlin, it is expedient that the U-profile forming the fork is screwed to the part of the hook that reaches into the purlin, including the bottom of the purlin.
  • the overweight end of the locking bracket is connected to a downward weight piece, the weight piece assuming the function of the fork stop for the lifting fork .
  • the overweight end of the locking bracket is provided with a weight arranged on the top, and that the overweight end, relative to the purlin plane, is angled downward and the end region is designed as a fork stop for a lifting fork.
  • the fork stop for the lifting fork which is formed by a bend, can be made relatively short.
  • the locking position should be summarized again, the criterion of which is that when the purlin locked in the suspension bracket is lifted, the end of the bracket rests against the hook at an acute angle, and the angling of the locking bracket below the area or area delimited by the thickness of the suspension bracket Line lies essentially plane-parallel or parallel.
  • the purlin is only equipped on one side with a locking bracket which is rotatably arranged on a bracket joint.
  • connection according to the invention secured against unintentional lifting, of at least two roof trusses with a plurality of substantially horizontal purlins, each of which is formed with downward-facing support hooks which engage in hanging tabs, is explained in more detail in an exemplary embodiment.
  • Figure Z shows the system of arranging, connecting and locking binders and purlins as a compilation.
  • Figure 1 shows a connection joint between purlin and truss, the purlin in the longitudinal direction of its extension including the safety device in its longitudinal extension, as well as the hanging tab are cut in the middle: the longer, d.
  • Obese part of the locking bracket has an additional weight-increasing fork stop for engaging a lifting fork used in assembly.
  • Figure 2 shows an analog design to Figure 1, but with an additional weight arranged in the end region, which is also effective as a fork stop.
  • Figure 3 also corresponds to Figures 1 and 2; the additional weight is arranged upward on the locking bracket, and an end angled by 90 °, which is also effective as a fork stop, directed downward.
  • FIG. 4 shows FIG. 1 with the lifting fork attached in the lifting or lifting position of the purlin.
  • the bearing fork formed by a U-shaped profile 1.2 for receiving the bow joint 1.4 is connected from below to the purlin floor by screws 1.9, which in turn engage in corresponding threads of the inside hook 1.1.
  • the position of the bow joint 1.4 is determined so that the shorter, d. H. the less important part of the bracket 1.3 is directed approximately parallel to the hook 1.1 with its bracket end 1.3.1, and with its angled 1.3.2 adjoining the inner edge of the flap 2.1, and the further angled 1.3.3 leads to the bow joint 1.4.
  • the subsequent overweight end 1.3.4 leads into a fork stop 1.5 which reinforces the overweight and is angled by 90 °, this additionally reinforcing the excess weight.
  • the bracket end 1.3.1 lies at an acute angle on the hook surface, while the bend 1.3.2 of the locking bracket 1.3 downwards delimits the area delimited by the thickness of the suspension brackets 2.1 or line lies essentially plane-parallel or parallel. It is thus clearly locked against unwanted excavation.
  • FIG. 4 If the overweight end of the locking bracket 1.3 is raised by a lifting fork 3, FIG. 4, then, as an embodiment according to FIG. 1 shows in the unlocked position, the purlin can be easily lifted by the lifting fork 3.
  • Figure 2 shows the equipment of the bow end 1.3.4 with a separate, downward weight 1.7, which can also take over the function of the fork stop.
  • the bow end 1.3.4 is designed with an upward weight 1.8, whereby section 1.3.4. same as in FIG. 1, transferred to a stop 1.6, which, however, can be kept shorter than stop 1.5 in FIG. 1 as a result of the additional weight.
  • the trusses and purlins are usually extruded aluminum profiles, while the hanging tabs and hooks, as well as the locking mechanism, are preferably made of steel.
