Abstract

A building foundation structure comprising a supporting and heat and moisture insulating layer (17, 18, 40), preferably of foam glass, which rests on a flat and horizontal surface (51) of a ground layer (50), and metallic foil (111) that covers the horizontal area of the foundation structure, in order to prevent moisture and smell,.for example jusmin odour, to propagate upwardly through the supporting and heat and moisture insulating layer (17, 18, 40).

Description

A kind of foundation structure

Technical field

The present invention relates to the sort of building infrastructure of claim 1 prelude branch qualification before.

Particularly, the present invention relates to a kind of foundation structure that is bearing on the soil.The soil generally will be handled through draining, and a kind ofly has a disrumpent feelings layer of capillary material, and for example crushed stone is dispersed on the plane upper horizontal surface in soil, and the granularity of described material is 2 to 4 millimeters.

Background technology

As everyone knows, we have obtained many experiences in long-term Foundation Design operation process, and the basis moisture in its use that is bearing on the soil may move in the building that is built on these bases by foundation structure.And smell also may penetrate the basis.Have been found that: the smell in soil itself, especially " jusmin " smell may see through these existing foundation structures.

Except can not seeing through these smell/, also requirement can be built up foundation structure fast, at low cost, and the impermeability of structure is also wanted to satisfy some and can be joined requirement in the foundation structure well to.

Summary of the invention

Therefore, one object of the present invention is to provide a kind of smell/can not see through and be easy to manufacture with lightweight component the foundation structure of required size substantially.

Can not see through the jusmin smell and also can be installed on the area supported by the paillon foil of long-term (for example about 100 to the centuries) being kept perfectly property under installation environment, this area supported can be a leveling course that is positioned at the top, building site.This paillon foil often is exposed under the operation of underground steam and ambient moisture, and underground steam and ambient moisture often are acid or contain mordant material.Therefore, preferably select a kind ofly can resist this environment for a long time and the jusmin smell is had impervious metal foil material.

Work as metal forming, aluminium foil for example, substantially directly be placed on the leveling course in soil, thereby when making metal forming and granular material in the described layer directly contacting, this paillon foil preferably has bigger thickness, for example thickness is about 0.1 to 1 millimeter, and purpose is to guarantee that to this paillon foil imposed load and when paillon foil is contacted closely with leveling course this paillon foil can not penetrated by basic components at building.Metal forming with this thickness can be manufactured into material webs or carry by this package, and can be at the scene of foundation structure with its from package launch and lay to the building site.This paillon foil also should have good tear strength, occurs the possibility damaged when the lay to reduce paillon foil.For some reason, if the width of paillon foil is less than the width of foundation structure, so can a plurality of paillon foils of different length are placed side by side and form a seam betwixt in the mode that adjoins each other, overlapping seam for example, thus guarantee that smell/can not see through this paillon foil layout.Overlapping paillon foil has the width that is suitable for this respect, and can comprise the paillon foil of a band or glue-line, adhesive tape or certain easy deformation, preferably include a compliant foil, and this paillon foil has very big width on the fabric width direction of overlapping paillon foil, can not see through smell and smell thereby can leak direction along air in the zone of a broad.Under the normal condition, it is just enough that an overlapping seam is set between adjacent aluminium foil band, because this seam is usually along its whole length effect of being under pressure.Certainly, before the lay tinsel, should cover this horizontal surface with plastic foil, for example purpose is to prevent that sand/gravel from entering in the overlapping seam between adjacent aluminium foil band.In one embodiment of the invention, if desired, for example consider for the angle of carrying, this aluminium foil can be laminated together with plastic foil, but the paillon foil that the used thickness of the present invention allows smell to see through more greatly and not is preferably aluminium foil, and this aluminium foil can be under its environment of living in (being generally corrosive atmosphere) being kept perfectly property for a long time.Most of plastic foil generally all will lose integrality under this environment in the same time period.

In another embodiment of the present invention, certainly can the smell paillon foil will be prevented, aluminium foil for example, be placed between two insulation material layers, and these two insulation material layers are included in the foundation structure, and in this case, aluminium foil can be thinner, because heat-barrier material has formed level and smooth, a uniform area supported, paillon foil can launch on this area supported.

The objective of the invention is to realize.The appended again independent claims of the present invention limit, and other embodiments of the invention can be limited by dependent claims.

In most preferred embodiment of the present invention, at first provide a ground by the mode that water is drained, layer overlay has capillary disrumpent feelings material on this ground then, for example granularity is 2 to 4 millimeters a rubble, then, this layer is carried out smooth, thereby obtain a plane horizontal surface.

One or more standard-sized prefabricated plates closely are laid on the first floor on the rubble, and this prefabricated plate for example can be a rectangular thin plate, and can be made by porous heat insulation material (for example thickness is 50 millimeters foamglas ).Can select to be close to the such thin plate of this another layer of first floor thin plate lay, and make the skew of the seam on the relative first floor of the seam between adjacent sheet certain distance on the second layer.

When these thin plates are connected together, should realize as far as possible that liquid seal connects.The heat-barrier material of this porous is preferably foamglas , or has minimum absolute water absorption rate or water absorption, has high resistance to pressure and insect protected and can effectively heat insulation and non-proliferation.

These isolation layers are generally surrounded by a framework, and this framework can be made up of a plurality of U-shaped beams of being made by metal sheet roof covering, and wherein the concave side of each beam is towards the inside of basic components.The high pressure heat-barrier material has been filled in zone in the framework, for example two laminations of being made by porous heat insulation material (2 * 100 millimeters foamglas ).Can make the framework of basic components keep stable the mode that an I ellbeam of being made by metal sheet roof covering is installed on the described framework by a U-shaped beam that is parallel to framework.The sheet-metal beams of these basic components links together mechanically, thereby makes these basic components keep stable.The thickness of these basic components for example can be 200 millimeters.In basic components, use U-shaped beam and I ellbeam to mean: can be by in the recessed portion that those sheet section in abutting connection with the beam body is inserted to the beam body and the porous heat-insulating thin plate is bonded to Liang Tishang according to definite shape.In addition, the upper horizontal flanges of these beam bodies will provide anchor point for the wall that is built in the building on these foundation structures.This building can be a kind of prefabricated box structure, and this structure is normally produced in distance foundation structure has the factory of certain distance.Perhaps, basic components can be respectively installed on the foundation structure, and timber member then that some are in bulk or frame type house are installed on these basic components and anchor it on the metal sheet roof covering flange.

Owing to we have found that: under the situation that the relatively poor paillon foil of smell permeability (for example plastic foil) is sealed, in fact smell and smell still can make a circulation to see through these paillon foils, so we preferably use a kind of by metal alloy or metal sealant.

We recognize: even thickness is little of 0.01 millimeter, aluminium foil still can provide required air impermeability, certainly thicker aluminium foil will provide higher reliability, but also help the construction of foundation structure, because above-mentioned this aluminium foil can transport with the form of package, this package can be unfolded with smooth, then it is laid on the foundation structure.
