RIVET FIXING
Fixed/Stop point – Sliding/Go point –Rivet Fixed
Where panels are fastened to the supporting frame with a combination of fixed/stop and sliding/go points, each panel no matter what size will have 2 fixed/stop points and the rest left as sliding/go points.
The 2 fixed/stop points support the weight of the panel and ensure the panel stays in position and prevents rotation of the panel. The sliding/go points resist the wind loading, while accommodating any panel or support frame movement.
The choice of where the fixed/stop points are to be is important to prevent any risk of the panel cracking.
Selection of Fixed/Stop Point
The two fixed/stop points should never occur on the same profile. The two fixed/stop points must be located near the horizontal centre line of the panel. If there is no central fixing then use the next row closest to the centre line. This means that two profiles are needed. This is straight forward where there are at least two profiles in the middle area of the panel.
More commonly, there is only one profile in the middle area of the panel. Here, the rule-of-thumb is that the fixed/stop points are located to the centre of the panel and to the left joint profile. Alternatively they can be located to the centre and right joint profile. Whichever one is used all panels must be the same.
It should never be allowed that the fixed/stop point of two adjoining panels occur on the same joint profile.In situations where narrow panels with only two side fixings are used and the fixed/stop points of adjacent panels will be next
to each other, the support frame will need to be amended. The metal support frame behind the vertical joint which is usually a T profile will have to be substituted with two L profiles. This will separate any panel connection. This may also result in having a “U” bracket instead of the normal angle bracket.
