Since the lower density of the foamed thermoplastic, which ultimately accounts for the weight advantage, has a direct effect on the stability, the challenge for the product developer is the structural consideration of this point in the component design. Along with this, the fastening concept must also be reconsidered, since conventional self-tapping screws are not designed for these altered material properties and therefore quickly reach their limits.
In addition, thanks to its approvals, it can also be used on the international market. Suitable accessories: FR-Tool

The certified CROSSFIX® system is the first choice among architects, manufacturers and developers when it comes to sustainable substructures for facades.
The current part of our guidebook deals with the use of through bolts and presents the possibility of anchoring by means of an injection system. Correctly inserting through bolts Through bolts belong to the torque-controlled anchors. They are activated by applying a predetermined torque. Too little torque can result in the anchor slipping and the fastened component sagging.

During the development of the two profiles, it was especially important to optimally coordinate them with each other and ensure they work well together. For example, the profile leg of the Pro BSOP-HL is slightly slanted, which makes it easier to accommodate the Pro-SOP basebead profile.
Above-rafter insulation is considered to be energy-efficient roof insulation, because the rafters are correspondingly over-insulated as potential thermal bridges. As the insulation is built on the outside of the roof, the existing interior is retained in this insulation method.
With the dimensioning software for through bolts EJOT offers a very helpful tool for static initial sizing of building projects.
Wixom, MI, USA – EJOT Fastening Systems LP was named a 2020 Automotive News PACE Award winner at an awards ceremony on April 28.
In the first articles of the heavy-duty anchor guide, we dealt with the type of base material and its requirements for fastening elements.
Experts call it “circular building”. Wood is the dominating raw material for the TEC CENTER: A supporting structure out of high-strength “Baubuche” (hardwood laminated veneer lumber), walls out of “Holzsandwichtafeln” (CLT-technology), ceilings out of “Brettstapel”, partly as composite wood structure, dividers for the office space out of wood frame walls with “Lehmbautafeln”. Facade greenery, green retention roofs for water retention, photovoltaic and geothermic complement the integral concept.
For approval-relevant applications the special screw EJOT Delta PT® is used for fixing the attachment. Attachments can be directly fixed to the angle with the Delta PT®, additional aids or work steps are not required.
In combination with Multifix USF injection mortar for winter, the fastener can also be used at temperatures well below freezing point.
Wood is the dominant raw material for the TEC CENTER: A supporting structure made of high-strength structural beech, walls made of wood sandwich panels (CLT technology), ceilings as board stacks, partly as wood composite ceilings, office partition walls made of wood stud walls with clay building panels. Charging points for e-mobility in front of the building, green facades, green retention roofs for water retention, photovoltaics, geothermal energy with heat pump complete the holistic concept.
A completely different challenge becomes apparent in many areas of industrial production: the trend to-wards miniaturisation of entire structural units and a simultaneous weight reduction of the components. Representative for many other sectors is the industry of mobile means of communication, for example smart phones, where every gram and every millimetre which can be saved counts for competitive advantage. It is now possible to produce a DELTA PT® screw for direct assembly in thermoplastics, designed as a micro screw, with a nominal diametre of 1 mm.
To achieve this, CO2e emissions must be significantly reduced before 2030 and be at zero emissions from 2050. Heat waves, droughts, heavy rains with flooding and melting glaciers have long since reached us.
Numerous people lost their lives as a result of the direct and indirect consequences of the disaster. An area of around 6,400 km² around the damaged power plant had to be abandoned due to the high radiation exposure. It was presumed not to be usable for humans for hundreds, if not thousands of years Regaining usefulness “Let’s Green It” – this is the motto of the German-Ukrainian consortium RODINA - ENERPARC AG.
Alternative materials are also used in many applications. For example, EJOT's high-precision components for the high-voltage range of electric vehicles are manufactured from copper instead of steel in a complex, multi-stage cold-forming process. In combination with another EJOT manufacturing specialty, the plastic injection molding, cold massive forming is also the basic technology for special metal-plastic components.

Another risk is that dust can settle between the applied material and the rainwater does not drain away over the years. In the event of a leak, it can be difficult to locate the source and normally only a complete refurbishment can fix the problem.
The anniversary slogan – "EJOT. Bringing it together" "EJOT. Bringing it together" – the slogan for the 100th anniversary expresses the great diversity that characterizes the EJOT Group: Technical innovations, partnership with customers and suppliers who get more than "just" a screw at EJOT. Curiosity, openness and the joy of experimentation are also part of the EJOT philosophy, as is an open and transparent corporate culture with fair dealings with each other.
Professional selection and correct installation are critical factors in the long-term suitability of the ETICS to do its job. And the strength of the product configurator lies precisely in professional selection.
In addition, there is no security against turning back that could prevent the screw from being unintentionally loosened and the tightness from being lost. As a result, a secure connection cannot be established.

Adhesive test: This is how you can be sure! At the beginning of the adhesive test, it is important that the surface to be glued is treated with a cleaner specified by EJOT or the window manufacturer.
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.
The new and modern premises will be located by a good transport connection along Road 8 near Turku. They are built entirely for EJOT Sormat Oy's current and future needs.
EJOT also commits itself to respect human rights and the environment and to take responsibility for its own supply and value chain. The central contact person at EJOT for indications and complaints regarding the aforementioned is Winfried Schwarz, who is also the Chief Compliance Officer and Human Rights Representative of EJOT.
It can be difficult to keep track of everything.
Green Product Development: Another starting point towards a more environmentally friendly way of doing business is the development and research of alternative plastic materials. As part of this, we have launched two projects that focus on the use of alternative plastic materials: Our 1st project highlights the use of so-called "recyclates", i.e. materials which consist of 100% recycled processes.
The winners in the seven categories were announced at the beginning of November. The "Factory of the year" competition, run by management consultancy A.T.Kearney and the trade journal 'Produktion' for the 27th time this year, is considered the hardest and most traditional competition of its kind.
In the application reality, a multiple repeat assembly is thus almost impossible, since only one thread turn is engaged in the screw-in sheet metal.
In summer, vertical greening provides shade for the façade, keeping the interior pleasantly cool, while in winter, it has a heat-insulating effect. In addition, it has a positive effect on sound insulation.
Two types of screws in industrial lightweight construction In the field of industrial lightweight construction, we basically differentiate between self-tapping (also called thread-cutting) and self-drilling screws. Let's take a closer look at the respective properties of these screw types:
An additional, reduced embedment depth of 35 mm is now possible for multiple fastening of non-load-bearing systems in concrete (ETA 18/0221) using the JC2 concrete screws with a diameter of 6 mm and hexagon head (KB), truss head (FR) or countersunk head (ST). As well as the two installation depths of 35 or 40 mm for multiple fastening, a third installation depth of 55 mm can now be used for single fastening. This gives contractors even greater flexibility for application while at the same time reducing the risk of colliding with the installed reinforcement during fastening.
The office building itself is designed to be an immersive experience. Behind its window-rich facade, it houses nearly 48,000 square metres of office space spread across eight floors.
A component is usually subject to several types of loading at the same time. If the resulting stresses exceed the limits of a component, such as the minimum yield strength (RP02) or the minimum tensile strength (Rm), permanent deformations or even fractures occur. Therefore, load limits are checked and documented as part of an approval. The resulting types of stress differ depending on how the external forces act.
The need for alternative forms of power generation has never been greater. There is an urgent need for alternatives to the fossil and nuclear energy source that are still in widespread use.
Caution also applies if the drilling method used deviates from that required in the approval, e.g. drilling is carried out with an impact, although the ETA of the washer anchor describes a rotary drill position for the substrate used.
Oxidation The resulting corrosion products are firmly adhering, loose or soluble.
