Definitions
- the invention relates to a substructure for buildings.
- load-distribution layer On soft ground to be built structures can be supported by pile foundations and secured against settling movements. Between the piles (below) and the structures (above), a load-distribution layer should be regularly arranged in order to be able to introduce the loads resulting from the structure into the piles.
- the load distribution layer must have a certain thickness to fulfill this task and consist of certain material.
- load distribution layers of sand are known.
- Object of the present invention is the change of the load distribution layer such that the substructure can be constructed more cost-effective, more stable and / or faster overall.
- the substructure according to the invention results from the features of claim 1.
- the load distribution layer here is generally a combination of a pourable material, such as sand, with an integrated honeycomb structure.
- the latter is intended in particular to prevent or limit lateral movements of the pourable substance, namely an escape of the pourable substance to the side due to the static loads of the structures.
- the pourable material advantageously has the same height in the load distribution layer as the honeycomb structure. Deviations are possible.
- the support elements stand on or in a supporting ground and extend through an insufficiently load-bearing layer up to the load distribution layer.
- the honeycomb structure predominantly, in particular exclusively upright walls.
- “Upright” in this case means an alignment also parallel to the main extension direction of the support elements. In this way, transverse movements of the bulk material in the load distribution layer are effectively prevented.
- the honeycomb structure has predominantly, in particular exclusively walls, which are directed perpendicular to the extent of the load distribution layer. With horizontally aligned load distribution layer so upright walls of the honeycomb structure arise.
- the honeycomb structure is upwardly - in the direction of the building - and down - towards the support elements - open. Water absorption and permeability are thereby optimized.
- a leveling layer preferably made of sand, is provided beneath the load distribution layer, into which the support elements extend.
- the leveling layer serves as height compensation for the support elements. The latter end with their upper end faces approximately at the same height. Exactly the same heights are not possible in most cases due to their construction. The differences can be compensated by the compensation layer.
- the thickness of the leveling layer is 1 cm to 10 cm. The thicker the leveling layer is, the greater its additional load-distributing effect. Ideally, no leveling layer is provided.
- the honeycomb structure has cavities with a diameter of 25 cm or more.
- the diameter should be measured in the direction parallel to the extension of the load distribution layer.
- the cavities are all approximately the same size as possible. Accordingly, the cavities do not have a circular cross-section.
- the diameter refers to the smallest diameter within a cavity. Depending on the direction of measurement, a larger diameter may also result.
- the honeycomb structure walls and / or cavities having 5 cm to 15 cm in height.
- the height preferably extends in the direction perpendicular to the extension of the load distribution layer.
- the load distribution layer can be made relatively thin overall. Accordingly, the reduced
- the honeycomb structure has perforated walls with a perforation of 0% to 40% of the total wall surface.
- the perforation for example in the form of equally spaced holes or other openings, allows a permeability to water and fine grain.
- 0% corresponds to a version , without perforation.
- the honeycomb structure can be formed from wavy curved strips, the strips being connected to one another in the region of wave crests and wave troughs.
- the peaks and valleys are not up and down, but laterally offset from each other.
- the strips described make it possible to form large-area honeycomb structures quickly and easily.
- the honeycomb structure has contiguous cells or cavities having an area of 400 cm 2 or more.
- the surface is preferably to be measured parallel to the extension of the load distribution layer.
- the honeycomb structure may have mutually adjacent cells whose walls are connected to walls of other and / or the same cells, wherein frictional connections between the walls for a load of preferably each about 1 kN are designed.
- Such resilient connections effectively prevent separation of the interconnected walls or malfunction of the honeycomb structure as a whole for most applications.
- the honeycomb structure has walls made of HDPE or other polymer materials.
- HDPE High Density Polyethylene
- the walls can also be formed from nonwovens.
- the honeycomb structure has in particular walls of 1 mm to 3 mm thickness.
- walls with a thickness of 1 mm to 2 mm are provided.
- the walls tend to be thicker the more perforations are provided.
- the support elements are advantageously columns with 40 cm to 80 cm in diameter and can be cast, for example, concrete.
- a grid arrangement of the support elements with a distance of 1.50 m to 3.50 m to each other.
- a fleece is provided on the leveling layer or in the same.
- the fleece is preferably a water-permeable textile layer with which, for example, a mixing of material above and below the fleece is avoided.
- a nonwoven fabric is disposed immediately under the load distribution layer.
- two or more load distribution layers are arranged one above the other, with distances to each other of preferably 0 cm to 50 cm, wherein the support elements can reach down to the lower load distribution layer.
- Tests have shown that two load distribution layers can provide better results than a single load distribution layer with the same total thickness as the two load distribution layers. This effect can be explained by the compaction of the material within the load distribution layer. The material can be better compacted successively in two flat load-distribution layers than in a single one high load distribution layer. It is also possible to arrange more than two load distribution layers one above the other with or without gaps.
- compensation layers are respectively arranged between the load distribution layers, with thicknesses of preferably 0 cm to 50 cm.
- thicknesses preferably 0 cm to 50 cm.
- one or more compensation layers have a changing thickness profile.
- a lower leveling layer between the load distribution layer and the support elements compensates for tolerances when setting the support elements. Further adjustments to the required exact height of the substructure are possible by changing the thickness of a further leveling layer between two load distribution layers.
- a possibly present nonwoven fabric is arranged at least under the lowest load distribution layer in the case of several load distribution layers. But it can also be provided under further or under all load distribution layers fleeces.
- FIG. 2 is a perspective view of a part of the substructure, 3 shows a cross section to Fig. 2,
- FIG. 4 is a perspective view of the substructure analogous to FIG. 2, but with three load distribution layers and compensating layers,
- FIG. 5 shows a cross section to Fig. 4th
- a building is to be erected on an unsustainable ground, namely a soft layer 10.
- a special substructure is provided. This has here columnar support elements 11 and a load distribution layer 12 arranged above.
- the support elements 11 are designed here as concrete columns that stand upright and extend through the entire soft layer 10 into a sustainable
- Compensation layer 14 if necessary, existing height differences of the support elements are compensated. At the same time, the leveling layer 14 can participate in the distribution of loads.
- the leveling layer 14 is covered by a water-permeable textile layer, a fleece 15. Immediately on the fleece 15, the load distribution layer 12 is arranged, on which, for example, an antifreeze layer and a road surface can lie (not shown) or a dyke structure.
- the load distribution layer 12 preferably has an integrated, three-dimensional honeycomb structure.
- the honeycomb structure is filled with compacted sand. Loads resting on the load distribution layer 12 are introduced into the support elements 11 through the sand and the honeycomb structure.
- the three-dimensional honeycomb structure of the load distribution layer 12 consists of meandering plastic strips 16 with upright walls. Due to the meandering shape, the impression of a nearly complete impression results for each plastic strip 16 sinusoidal course. Adjacent plastic strips 16 are - in the sense of a sinusoid - shifted by 180 ° to each other, so that upwardly and downwardly open cavities 17 or honeycomb arise.
- a plurality of plastic strips 16 are connected in advance to form a honeycomb unit 18.
- a plurality of honeycomb units 18 in the area of outer arches 19 and projecting fins 20 are then frictionally connected to one another.
- connecting means are used, such as mechanical type or by gluing or welding.
- the fins 20 are formed by interconnected ends of adjacent plastic strips 16.
- the height of the honeycomb structure and correspondingly also the perforated plastic strip 16 and the load distribution layer 12 is about 5 cm to 15 cm with a diameter of the individual cavities 17 or honeycombs of more than 25 cm and / or one of the cavities 17 covered area of more each as 400 cm 2 .
- the leveling layer 14 should be as thin as possible and has a thickness of about 1 cm to 20 cm. Ideally, no leveling layer is provided.
- the support members 11 are formed here as concrete columns with a diameter of about 40 cm to 80 cm.
- the individual columns in the grid at a distance of about 2 m to 3.50 m.
- the connections between the adjacent or successive plastic strips 16 are designed for a tensile force of about 1 kN.
- the material used is preferably HDPE with a wall thickness of 1 mm to 2 mm thickness.
- FIGS. 4 and 5 An extension of the substructure shown in FIGS. 2 and 3 is shown in FIGS. 4 and 5. Overall, three load distribution layers 12, 112, 212 and three compensation layers 14, 114, 214 are provided, namely alternately.
- the mat 15 is located between the lower load distribution layer 12 and the lower leveling layer 14.
- the support elements 11 extend as far as the lower compensation layer 14 or extend into it, as shown in Fig. 1.
- the compensating layers 14 are formed here in the longitudinal extent of the structure - arrow 21 - with a constant thickness. However, changing thicknesses are also possible in the extension direction, in particular to compensate for different heights between the soft layer 10 on the one hand, see FIG. 1, and the required height of the structure above the uppermost load distribution layer 212 on the other.
