Reparatur von Kantenschäden an der Schalung von Deckentischen.
Deckentische sind besonderen Belastungen
ausgesetzt. Die Logistik auf der Baustelle per Kran setzt insbesondere den
Kanten der Schalhaut zu. Auch beim Abschalen kommt es immer wieder zu
verletzungen am Rand der Tische zum Beispiel durch Verkanten.
Mit dem Emplica Plicafix 200 System, dem
DB4XL Zylinderkopffräser und der Kantenschablone wird die dauerhafte
Wiederherstellung einer scharfen und geraden Kante leicht gemacht.
Deckentisch mit beschädigter Kante
Zuächst muss die Kante und die Schadstelle
gereinigt werden. Auch Nägel, Schrauben
und Nieten müssen entfernt werden.
Am schnellsten geht das mit einer
Topfbürste.
Nach der grosszügigen Behandlung mit der Bürste
sieht die Kante nun schon deutlich besser aus. Auch Betonreste wurden restlos
entfernt.
Nun kann die Kantenschablone angesetzt, und
mit der Druckspindel an der Schalung arretiert werden.
Oberfräse ansetzen und einschalten, langsam
und kontrolliert an der Schablone entlang von links nach rechts ziehen (da sich
der Fräser im Uhrzeigersinn dreht).
Die Schablone ist so eingestellt, dass man
genau am Rand entlang fräst.
Mittels Druckluft von Staub und Spänen
befreien
Kleber (z.B. Emplica PUG PRO) sparsam auf die Kante
sowie am vorderen Kantenrand auftragen
Plicafix 200 Reparaturstreifen mit einem
Gummihammer vorsichtig einschlagen.
Durch das Fehlen der vorderen haltgebenden
Seite sollte der Reparaturstreifen noch für ca 30 min fixiert werden. Dazu
reicht eine Klemme wie im Bild aus.
mit einem Spachtel ausgehärtete Leimreste
entfernen.

How to repair damaged edges on slab form tables
Slab tables are exposed to great strain
during their use on site. The edges are usually the most vulnerable to damages
from cranes and lifts or releasing.
With the
Emplica repair strips system in combination with DB4XL router bit and
edge router guide, repairing these slab tables is very easy and simple.
Restoring a sharp, durable edge is done in
a few quick steps, as shown in our pictorial below.
Slab table with damaged edge
First, clean the damaged edge and make sure there are no screws, nails and rivets left in the plywood.
Concrete residue will be removed during the cleaning process as well.
clean edge
Now put the router guide into place and fix with spindle
Use the router along the guide with slow, controlled movements.
Always drive from left to right, if the routerguide is facing you. (because of the router bit’s clock wise turn)
The router guide will make sure the groove is right at the edge.
blow away dust and clippings
Use Glue (e.g. Emplica PUG PRO) very frugally and only into the edge, not the full flat surface.
Use a rubber hammer to gently fix the repair strip.
You may want to use a clamp to put on some pressure for 15-30 mins.
remove excess glue after curing with a spatula
seal the newly repaired edge

how to keep the emplica drill bit in shape and clean with resin remover
Contact with concrete
softens the phenolic film coating. By drilling through the film, the phenolic
resins will start sticking tot he drill bit. This can effect the cutting
performance negatively.
To clean your drill bit, a resin remover
should be used regularly to keep the blades and spurs in good shape. See how
our resin remover works wonders on a drill bit.
Emplica resin remover comes as a concentrated granulate that needs to be
solved in water.
Use the drill bit’s original packaging as a container and pour in 1 tsp oft he granulate and add 100 ml of cold water.
sink the drill bit into the solution and let rest for 1 to 8 hrs.
The solution will get a brownish color, this indicates that it is working.
Rinse the drill bit with lots of cold water.
dry the drill bit
apply oil to avoid rusting
finished and ready for more drilling
How to set plywood repair plugs perfectly flush
Setting plywood repair plugs in such a way, that the concrete surface
will later show no indentation requires a little understanding of physical
properties of wood and water.
Processed wood directly from the factory has a moisture
of ca. 8 per cent. Plywood panels, that have been used on site have a much
higher moisture content of ca. 30-50 per cent.
After setting the repair plug into the panel, it will
suck up moisture from the surrounding wood and swell. To avoid plugs from
sticking up from the panel’s surface, one must set them a fraction of a millimetre deeper so it has room to swell. We recommend half the thickness of a
fingernail.
Adjust depth stop of router to desired depth (we use a plug to see how deep we need to set the depth:
drill until depth stops
You can see the hole is declining towards the middle in the shape of a funnel. this gives room for excess glue to expand.
Apply glue to the edge
Set in plywood plug with a rubber hammer. As you can see in the picture below, it is a little "too deep". But as explained above, this is what we want. The plug will now suck up moisture from the panel and swell. it will be flush with the rest of the panel within a few hours or latest for the next pour.

Local newspaper Hürriyet (english) has an article about the tunnel.
here is a nice animation of the construction:
and here a video of the works.
and of course: discovery channel made a documentary.

The human factor
The only way to keep quality at highest standards is to test and try the real product over and over again. No machine and no statistics can simulate reality.
Humans have the ability to see something and make instant decisions based on experience. Machines need to be programmed to do so. But what if the machine program is missing some info that has never been experienced and dealt with before?
Only the human brain is able to anticipate what impact a certain characteristic will have later on in the life of a product.
And this anticipation can happen within fractions of a second.
Usually, experience plays a big part in this decision making process, but also training and a good working environment that supports individual decisions and lets people be creative.
So what do we do at emplica? We make prototypes and ship them back and forth and test and test again until a final product evolves. The more complex the product, the more back and forth and the more testing and trials. Maybe even involving a client in this process to ensure a product that does what it is supposed to do and is better than a previous version.
Nothing beats human experience and creativity.
At emplica, every product we offer, has gone through these processes of prototyping, trials and improvements until we have decided that we can take responsibility for it.
Our starter kit has been designed to fulfill exactly its needs. We took away and added where necessary until we found there is nothing better.
Our drill bits have been designed to fulfill their purpose the best way possible. With multiple necessary, sometimes conflicting characteristics, it took many months for our drill bits to evolve into a final product.
Emplica's repair plugs and repair strips have been used by the thousands internally before a packaging was designed and the products being offered to our customers.
Why do we do this? We believe that quality and usability are the most important ingredients to a successful business in the long run.
Low prices almost certainly lead to disappointed customers, as quality suffers.

"Thats impossible!"
Never accept this as an answer if you want to achieve something better.
Since i started my company, i have been working on improvements of our products almost on a daily basis. This usually takes place after office and involves long evenings.
Often, i get to a point, where my engineering partners tell me that what i want is not possible without major disadvantages to existing characteristics. And almost just as often, i believe them. After all, they are the professionals right? They have studied this in university or college.
But one of the major advantages of an amateur is the fresh and unorthodox view at things.
Don't let them stop you just because they don't see a way. There is always a way.
Sometimes i have to use very rude methods to improve our products, using the completely "wrong" tools to work on them. Often, in a destructive way. But in the end, I get to the result I wanted and the design is right.
What happens then is this: I hand over my "piece of art" to the engineers and let them work on the fine tuning and have them make another prototype resembling what i wanted. And I love their reaction when it actually works!
Engineers tend to be stuck on their paths of thinking, especially, when they're not the user of their product. An outside view can change so many things.
Francis Picabia, a french writer in the 19th and 20th century once said:
“Our heads are round so our thoughts can change direction.”
If you stick to this, you will get where you want to get.

Repair or resheet?
A quick guide for the formwork maintenance professional.
Concrete surface is a delicate matter and measured very individually. Following pictorial is in our opinion suitable for most forms, even when used for exposed concrete walls.
Some of our clients have even lowered the maximum amount of repairs allowed per panel and square meter or 10 square feet, to avoid any discussions with architects...
As a general rule, we recommend to NOT put more than 4 plugs per square meter / 10 square Foot. And NOT more than 10 plugs per Panel. If the panel is less than 1 sqm / 10sqft, then the maximum is obviously less than 4 plugs per panel…
We presume you know how to use our repair system. Badly set repair plugs are never accepted. You can always watch our tutorial videos on youtube: http://www.youtube.com/emplicaswitzerland
And there is another recommendation:
Please do not repair formwork that you have rented, unless you have clear instructions to do so by the owner of the formwork.
Repairing rented formwork often results in quarrel.
For obviuos reasons we cannot be held liable for any damages by the use of this guide
but lets get started:
Above panel has 8 damages, its ok to repair
Above panel has 16 damages, resheeting is recommended.
Above panel has 4 damages within 1 square meter / 10 square feet space. Repairing is ok
Above Panel has more than 4 damages on a space of 1 square meter / 10 square feet.

politicians and construction - does it work?
Alone the Elbe Philharmonic Hall has doubled costs and construction time during construction. The Berlin Airport's construction disaster is in the german media almost every week with new delays and risen costs as well as chaotic conditions on site. Contractors have no idea what to do and where and when due to missing plans due to change of planning offices... Planned to open in june 2012, the opening date is now pushed to 2013....while costs are exploding and basic airport safety (fireproofing etc) rules have been neglected to great extends and need to be re-planned and built.
Do you have similar experiences about your tax money being spent by ambitious politicians? Or do you think prestigious objects like those two can never be built within time and cost frames?
How can public building be organized better?
