Description

Einlagen für Rammköpfe Bei der Durchführung von Bauarbeiten und zur Sicherung von Raustellen werden Rammpfähle - die auch Profilform haben könnenmit Hilfe von Maschinenrammen an deren Schlagende ein Rammbär angebracht ist, in das Erdreich getrieben. Dort wo@der Rammbär auf den Rammfahl auf trifft darf wegen der Wiederverwendung der Rammpfähle an diesen keine Stauchung entstehen. Um das zu verhüten werden auf die oberen Enden der Rammpfähle sogenannte Rammköpfe aufgesetzt. Die Rammköpfe sind so ausgebildet, dass sie mit ihren unteren Ende auf das Profil der Rammpfähle gresteckt werden während in einer, dem Rammbär zugekehrten Vertiefung Holzplatten eingelegt werden, auf welche der Rammbär seinen Treibschlag ausübt. Derartige Holzplatten haben von der Anwendung her keine lange lebensdauer. Eine weitere Notwendigkeit macht Holz ebenfalls ungeeignet. Die beim Rammen, am Rammkopf entstehende Wärme muß abgeleitet werden. Erfindungsgemäß wird und vergeschlagen, die Einalgen für den Rammkopf anders aufzubauen. Zwischen Platten die einen faser- und/oder schichtförmigen Aufbau haben werden wärmeableitende Stoffe wie z. B. Kupfer, Messing, Aluminium usw. eingelegt oder eingearbeitet. Diese Einlagen können in ihrem Querschnitt auch Profilform haben. Deposits for ram heads When carrying out construction work and for Rough sites are secured by driven piles - which can also have a profile shape With the help of machine rams, at the end of which a ram is attached, into which Driven into the ground. Where @ the Rammbär meets the Rammfahl because of the Reuse of the driven piles on these no compression occurs. To prevent that So-called ram heads are placed on the upper ends of the piles. the Ram heads are designed so that their lower end on the profile of the Driving piles are inserted while in a recess facing the battering ram Wooden plates are inserted on which the battering ram exerts its driving blow. Such wooden panels do not have a long service life in terms of application. One further necessity also makes wood unsuitable. The one when ramming, at the ram head the resulting heat must be dissipated. According to the invention and proposed, to build up the algae for the ram head differently. Between the plates the one fiber and / or layered structure will have heat-dissipating materials such. B. copper, Brass, aluminum etc. inlaid or incorporated. These deposits can be in your Cross-section also have a profile shape.

Claims

Protection claims

1. Deposits for ram heads characterized in that the same one, in the production of liquid, pasty, solid, powdery and / or fibrous and / or layered structure, optionally have reinforcement inserts, that their production requires pressure and / or negative pressure and / or heat is and that to dissipate heat Protection claims for the function, Intermediate layers in front of @ ends are in the form of plates or strips, whole or open, in their. Cross-section also designed as a profile, lying loosely between @ e @ inserts or are firmly connected to them.

2. According to 1, characterized in that the deposits and the heat dissipating Intermediate layers joined to form a solid package during manufacture or before use will.

3. According to 1 and 2, characterized in that the heat sink direct Have contact with the ram head.

4. After 1 - 3 characterized in that both the ram head as the inserts for the ram head are also designed so that cooling media are passed through can be.

5. According to 1 - 4 characterized in that the deposit package is designed it is instead of the ram head, placed directly on the pile and as Ram head can be used.

6. According to 1 - 5 characterized in that the deposits and the heat dissipating Intermediate layers are constructed in such a way that the same gaps in the relieved state form.
