EJOT industrial fasteners can be found in countless assemblies worldwide.
Mistake no. 2: Angled through bolts It seems that the installer knew that edges are critical, because he tried to prevent splitting by installing the through bolts at an angle.
In order to assess the suitability of profiles according to these different requirements, various classifications have been created, with which a testing institute can assess the products in terms of movement absorption and imperviousness to driving rain.
To answer these questions, we first need to examine some basic issues.

The metal cone must travel a certain distance inside the drop-in anchor in order to properly expand the sleeve in the borehole. The ETA-controlled setting tool ensures the correct distance. Advantages: Easy assembly (no setting tools, exception: drop-in anchors) Immediate load-carrying capacity (no curing times) Self-locking load bearing capacity: As soon as load is introduced via the add-on part, the cone bolt continues to pull into the sleeve.
Let´s take a closer look at the two types of installation below: Pre-positioned installation The process of pre-positioned installation consists of several steps: First a hole is drilled according to the product data and cleaned using a cleaning brush and blow-out pump. (1-3) In the next step, the anchor is inserted into the fastening base.
Now, to understand which side of a ceiling is the torn side and which is the non-torn side, we can imagine a simple, thin board that crosses a stream as a footbridge. The dead weight of the board and the added weight by people cause the board to bend. The bending stress within the board results in a compression load on the top of the board and tensile stress on the underside.

It is our claim to be valued as a reliable partner by your side.
Expert EJOT staff repair the defective tools to prevent down-times. If possible, we carry out the repairs directly on site. If the damage is too severe, the repair will be done in one of our EJOT workshops.
Example: With a 100 mm-long anchor which is embedded 70 mm in the substrate, a fastening thickness of up to 30 mm can be achieved.
For example, the exposure to corrosion is much higher in environments with seawater or in the chloride-containing environment of swimming pools than in other areas.
In addition to corrosion protection, this top coat protects against chemical and mechanical effects and is responsible, for example, for weather resistance and appearance.
Therefore, only the formulas for the minimum distances with pilot hole in accordance with DIN EN 1995-1-1: 2010-12 need to be taken into account. However, the extensive tables and representations of DIN EN 1995-1-1: 2010-12 quickly make it clear that the necessary edge distance cannot be determined without special knowledge in relation to the timber construction standard.
Self-drilling screws are required to attach mounting rails in the roof cladding, e.g. for a trapezoidal profiled sheet, or to connect individual mounting elements to one another.
For trapezoidal profiled sheets and sandwich panels, there is the alternative option of screwing the mounting rails into the roofing in addition to fastening them in the roof substructure.
In order to prevent any leakage on the roof due to the roof perforation, the solar fastener is either combined with an EJOT ORKAN storm washer and a E16 sealing washer or a fibre cement sealing element.
"EJOT is clearly committed to the Tambach location and confirms this through steady growth, continuous investment and high regard for the employees", said the panel in its speech.

In addition to the form, the colour of the facade also plays an important role. Manufacturers of profiled steel sheets have long been offering a wide variety of colour combinations. To obtain a continuous colour image, up to the smallest detail, even the fastening elements such as screws, rivets and storm washers are produced in the corresponding RAL colours.
Fastening to timber substructures In order to achieve high load-bearing capacity values in timber, the screws have a coarse thread.
With an area measuring 600 square metres, the east façade is the largest vertical garden in Germany to date (as of May 2022).
With ETICS, the maximum possible characteristic wind load according to the ETICS approval is wek = -2,2 kN/m². known wind load If the wind load is known, it can be entered directly as - characteristic wind load wek (value without safety factor) or - design value wed (value with safety factor). Determining the wind load Otherwise, the wind load for area A (edge area) is calculated according to DIN EN 1991-1-4/NA:2010-12 using the simplified method.
