Definitions

  • the present invention relates to a building foundation with at least one foundation element, which preferably comprises a wood pile anchored in the ground by ramming and a load-transfer cap which can be slipped over the upper end of the wood pile, which introduces building loads into the wood pile and preferably has positive connection means for connecting a building element to be supported.
  • the Lastabtragskappe forms an at least fluid-tight, preferably also gas-tight, pile protection sleeve which surrounds the wood pile from its upper end down to a moisture change area down fluid-tight.
  • the invention further relates to a method for producing a building foundation, in which at least one wooden pile is anchored in a water bottom, so that an upper portion of the wood pile protrudes above the water level, wherein the wood pile is provided at its upper end with a load transfer cap, so that the Wooden post is enclosed under the water level by the Lastäbtragskappe.
  • Lastabtragskappen In order to be able to initiate the building or building loads better in the anchored in the ground or ground wooden piles, Lastabtragskappen can be slipped over the upper ends of the wooden poles, where then the other parts to be supported structural parts are connected. Such Lastabtragskappen hold the body of the wooden pile in particular transversely to the fiber direction together and prevent the wood pile under the considerable building or building burdens apart or otherwise damaged. As is known, the strength of wood is strongly dependent on the direction and is considerably reduced transversely to the fiber longitudinal direction. In addition, such a load transfer cap can distribute the load entry over the pile cross section. In other words, such load-transfer caps improve the ability of the wood pile to absorb the shear stresses induced transversely to the fiber's longitudinal direction by the vertical structural loads.
  • a building foundation according to the preamble of claim 1 shows the GB-A-2028405 according to which a foundation pile is surrounded by a polypropylene jacket, wherein the space between the foundation pile and the polypropylene jacket is foamed with a polyurethane foam. Furthermore, the beats GB-A-21 23 872 To provide the buried end of a wood pile with a polypropylene shell, which sits on the inside of the wood mitred fins.
  • the present invention seeks to provide an improved foundation of the type mentioned above and an improved method for its production, avoid the disadvantages of the prior art and further develop the latter in an advantageous manner.
  • the wood pile used as a foundation element should be better protected against rot and at the same time reliably intercept even high structural loads.
  • the load transfer cap forms an at least fluid-tight, preferably also gas-tight, pile protection sleeve which encloses the wood pile in a fluid-tight manner from its upper end down to a moisture change region.
  • the wooden pile is kept evenly or evenly dry by the load transfer cap. Due to the double function of the load transfer cap, which on the one hand initiates the structural loads in the wooden pile and on the other hand forms a moisture barrier, the structure of the foundation element can be kept simple overall despite the additional rottenness protection. In particular, can be dispensed with separate, additional rottening measures, such as separate Dachpappenumwicklisme etc.
  • the foundation of the building can advantageously be used in hydraulic engineering.
  • the wood pile is in the water and / or groundwater, so that a part of the wood pile is anchored in the water bottom or ground, a second part of the wood pile is under water and a third part of the wooden stake extends over water.
  • the load transfer cap which is slipped over the upper end of the wood pile, to below drawn the water level, wherein a Lastabtragskappeninnenraum in which the wood pile is received, with liquid to above the water level addition, preferably is substantially completely filled up to the upper end of the wood pile.
  • such a design of the moisture barrier of a standing in the water wooden stake can be advantageously prepared by the Lastabtragskappeninnenraum is filled to the upper end of the wood pile by means of an initially open filling and / or vent with liquid and then lying above the water level filling and / or vent in the load transfer cap fluid and gas tight, so that in the Lastabtragskappeninnenraum over the water level reaching liquid column is held.
  • the Lastabtragskappe can in principle be placed over the wood pile before or after the anchoring of the wood pile in the river bottom, it may be advantageous first to anchor the wooden pile without load transfer cap in the riverbed, then cut off the wood pile to the desired length and finally the Lastabtragskappe from above to put it over the top of the wooden post. Then, in the aforementioned manner, the load compartment interior is filled with liquid.
  • the Lastabtragskappe in the region of the upper end of the wooden pile, in particular in the region of the upper end of the Lastabtragskappe, a fluid and gas-tight sealable filling opening, via which the liquid, in particular water, are filled in the Lastabtragskappe or their wood pile receiving interior can.
  • the load transfer cap in the region of its upper end may also have a vent opening which can be closed in a fluid-tight and gas-tight manner, so that the air located in the load transfer cap interior before filling can be better displaced.
  • This would also make it possible, for example, to fill the load transfer cap interior with water from below, for example by pressing water between the wood pile and the load transfer cap via a filling opening provided at the lower end.
  • the filling opening and / or the venting opening can in principle be closed by various, preferably detachable, multiply closable closure means, for example they could be welded closed after the filling process.
  • the filling opening and / or the vent opening can also be formed in the form of a threaded hole and closed by a bolt, if necessary, with a suitable seal.
  • the vent opening could be formed by a vent valve, preferably a valve operating in the manner of a check valve, the air from the Lastabtragskappeninnenraum escape, but does not allow air to enter the load-discharge cap interior.
  • a wood pile used in hydraulic engineering ends the load transfer cap above the water bottom, in which the wood stake is anchored, so as to ensure that the above-mentioned second part of the wood pile is lapped by water, so that overall the entire pile evenly moist held and also the favorable anchoring properties of a wooden pile in the ground can be fully utilized.
  • the wood pile through its wooden surface - better than a concrete or steel pile - so to speak festseaugen in the body of water.
  • the use of the foundation of the building according to the present invention is not limited to hydraulic engineering, but can also be used advantageously in "dry" earthworks. It is provided in a further development of the invention that extends the load transfer cap into the ground beyond its moisture change area, so that the protruding from the ground part of the wood pile and the exposed in the upper, the moisture change layer of soil sticking portion of the wood pile of the Lastabtragskappe fluid-tight are enclosed.
  • the Lastabtragskappe may extend to about the depth of frost boundary of the soil in this, so that the portion of the wood pile in the transition region between soil and air and the uppermost layer of soil, which is exposed to the moisture, kept uniformly dry and preserved from the moisture change of the uppermost layer of soil is.
  • the envelope depth of the load transfer cap can be chosen differently. Preferably, it will extend at least 20 cm, more preferably 50 cm or more into the ground, so that no moisture change can occur on the wooden pile. However, the deeper into the ground reaching portion of the wood pile can remain free, ie not be enclosed by the Lastabtragskappe because in the said deeper soil layers no relevant moisture change occurs, which would cause the rot of the pile to be prevented.
  • the load transfer cap sits free of intermediate layers directly on the wood pile, so that the preferably fluid and gas-tight pile protection sleeve load transfer cap hermetically encloses the wood pile.
  • the Lastabtragskappe can sit with a press fit on the wooden pile.
  • the latter can advantageously be produced by pre-drying the wood pile. If the wood pile is dried sufficiently far enough, it contracts to a diameter with which it can be easily inserted into the load transfer cap. If the humidity increases again, the wooden pole expands again and the load-bearing cap sits on the wooden pole with a strong press fit.
  • the wood pile has sections with different cell density.

  • the entire wooden pile that is to say also the section located below the moisture change region, obtains such a compacted, permanent structural change with respect to its natural wood structure through pretreatment.
  • a structural compression so to speak in the manner of a Petrification, which reduces wood inclusions and increases fiber density and increases volume specific weight, significantly improves the fatigue strength of the wood pile.
  • Such a permanent wood structure change can basically be obtained by various pretreatments, in particular by a uniform radial pressing of the wood pile transversely to its fiber direction with sufficiently high transverse pressures.
  • this wood structure modification can be obtained by pre-drying the wood pile before slipping the load-transfer coping, lowering the moisture content of the wood pile to the extent that the outside diameter of the wood pile is reduced below the inside diameter of the load transfer coping, and the moisture content of the wood chip Wood pile after passing the Lastabtragskappe is again increased so that the wood pile undergoes a permanent change in wood structure by the increase in diameter associated with the increase in moisture content and the consequent constriction by the Lastabtragskappe.
  • the moisture content is lowered by the predrying to the extent that the wood pile a diameter taper - compared to its diameter at "normal" moisture content that occurs when stored in ambient conditions, especially when stored in the later intended installation situation - by at least 5%, preferably 10% or more.
  • the diameter taper can be due to the predrying in the centimeter range, in particular in the range of 0.5 to 5 centimeters, preferably 1 to 3 centimeters.

  • Said advantageous structural change in the wood structure can alternatively or additionally also be achieved by further pressing measures which may be used to support it.
  • the Lastabtragskappe can be heated and cooled after slipping back to press the wood pile transversely to its longitudinal fiber direction.
  • the body of the load transfer cap is formed perforation-free in an advantageous embodiment of the invention.
  • the Lastabtragskappe is formed completely perforation at least until and above the humidity change region. Possibly. Perforations could be provided in a section of the load transfer cap below the humidity change zone, ie where they are no longer harmful. In a preferred embodiment of the invention, however, the load transfer cap is formed completely perforation-free.
