Description

Concrete flooring base and construction method thereof

The present invention relates to a kind of building, flooring base and construction method thereof as wood structure building specially refer to a kind of concrete flooring base and construction method thereof.

In recent years, the floor heating method is adopted by people, hot water piping is distributed under the floor surface, from building of this floor surface heating.In this case, concrete pouring is formed a concrete flooring base on whole ground, and with each heating element, as hot-water line and electric heater be installed on this flooring base or within.

According to routine, concrete flooring base is formed by following method.At first, dig out the periphery and the main part of this edifice.Pour into a mould the concrete of sole plate then, treat this concrete setting after, hold up a temporary frame work in its surface, concrete is poured into this framework forms foundation wall.Carry out backfill after removing this temporary frame work, this base wall is enclosed part mound and compacting, after this fluid concrete forms a surface.

Yet, use this building method, banketing and tamping operation bothers very much, and the superpotential that increases construction cost is arranged.Particularly when a concrete flooring base is transformed and laid to an existing timber buildings, used banketing will be transported into by this house, and it is indoor so just to have made dirty.The preparation of being done for preventing to make dirty is assigned a work and is bothered very much, becomes a subject matter.

In addition, though the load of building itself is supported by sole plate, place the load of the weight on the floor then to be directly delivered on the concrete flooring base.Therefore, people worry banket soft part or similarly other parts depression appears.As remedial measure, concrete flooring base and foundation wall are linked, the weight on floor is just supported by sole plate like this.Yet, adopting this structure, heat spills and is lost to outdoor from concrete flooring base by foundation wall, and this has caused the problem of cutting a little less than the isolation performance.This problem is especially serious when using floor heating.

Therefore, first purpose of the present invention provides a kind of concrete flooring base, and it has removed above-mentioned common defective, has good intensity, and owing to being easy to provide a kind of isolation structure to be applicable to a kind of floor of floor heating formula.

Second purpose of the present invention provides a kind of floor construction method that is used for the concrete ground of above-mentioned concrete flooring base.

First purpose of the present invention is to finish by comprising a kind of concrete flooring base of following structure:

(a) the underground concrete sole plate is supporting position foundation wall thereon, and this foundation wall is supporting a position building thereon,

(b) a plurality of tubular bodies that are arranged in the part of surrounding separated from each other by this foundation wall; With

(c) concrete flooring base part that the outer surface with these tubular bodies pours into an integrated entity.

Second purpose of the present invention is to obtain by the method for building a concrete flooring base, this method comprises the steps: at the periphery of a building that is dug out and main part fluid concrete, form the sole plate that supports this building loading, on this sole plate, form foundation wall, a plurality of tubular bodies are set, these tubular bodies are arranged in the zone that is surrounded by this foundation wall, to be arranged in parallel on this regional all surfaces to well, and each tubular body and adjacent tubular body are separated slightly, form a concrete flooring base around the external surface fluid concrete of these tubular bodies.

By in conjunction with the description of following accompanying drawing to preferential embodiment, these and other purposes, features and advantages of the present invention will be more obvious.

Fig. 1 is the sectional view of expression one embodiment of the present of invention,

Fig. 2 represents the sectional view according to another embodiment of concrete flooring base of the present invention,

Fig. 3 represents the partial sectional view according to concrete flooring base of the present invention.

With reference now to accompanying drawing, the present invention is done detailed explanation.

Fig. 1 is the schematic cross-section of one embodiment of the present of invention, as shown in FIG., concrete flooring base according to the present invention comprises that (a) underground concrete sole plate position 11 supporting thereon foundation wall 13 of position, this foundation wall 13 supports a position building thereon, (b) a plurality of tubular bodies 21 layout that separates each other in 13 area surrounded of this foundation wall; (c) outer surface with these tubular bodies 21 is cast for the concrete flooring base part 25 of one.

In construction according to concrete flooring base of the present invention, at first dig out the periphery and the major part of a building, fluid concrete forms a plurality of sole plates 11 then.On this base 11, hold up a plurality of temporary frame works (omitting among the figure), concrete is poured into form a plurality of foundation walls 13 in these frameworks then,, place a plurality of stiffeners 15 therein in advance in order to work to strengthen.Remove this temporary frame work after the concrete setting in foundation wall, and the part of digging out around this foundation wall is gone in earthen backfill.Next step is provided with a plurality of gardens cylindricality tubular body 21.These tubular bodies 21 are arranged in parallel on by the whole surface of this foundation wall institute area surrounded, and each tubular body 21 and adjacent tubular body 21 are separated slightly.If desired, these tubular bodies can arranged superposed, leaves the gap betwixt.A plurality of small cushion blocks (omitting among the figure) at this moment to be provided, these small cushion blocks are placed on position above ground line GL separately,, make it slightly exceed ground line GL one segment distance, thereby make the concrete of being poured into a mould to penetrate into the bottom of tubulose 21 to improve tubular body 21.If use conventional method, tackle this part and banket, use this step of method of the present invention then to there is no need.

Next step provides an isolated part 23, makes its inside that abuts against foundation wall 15, and around tubular body 21 fluid concretes, forms concrete flooring base 25.Can on this flooring base 25, form desirable any type of floor later in this step.Fig. 1 shows the situation that adopts floor heating.Lay one isolated part 31, a plurality of hot-water lines 33 that will be used for floor heating then are distributed on this isolated part 31, and manage 33 upper berths at these and apply heat-storing material part 35, cover the floor skin section above and divide 37, as mat or similar item.For convenience's sake, omit floor joists and similar portions among the figure and can at an easy rate concrete be injected into underfloor space, so just reduced construction cost with a pipe.Particularly an existing timber buildings is being transformed, and form under the situation of concrete flooring base, plate panel removably, those tubular bodies are arranged in this underfloor space, and can by pipe with concrete pouring on those tubular bodies, make this operation very simple.In addition, those are that the construction that makes flooring base is only side by side arranged with the tubular body 21 that very in a small amount concrete uses, and almost cover the whole surface in this underfloor space.Use the large diameter tubular body to reduce the allowed band of arranging as the guaranteed strength requisite space.Though the diameter of tubular body 21 needs the space of filling to determine by following floor, and in fact its diameter approaches in the 20-50 cm range.Tubular body is the garden cylindricality not necessarily.For example a square cross section is also applicable.

Use tubular body 21 that flooring base only can be formed with a small amount of concrete, and before this concrete setting, keep its shape in good condition.These tubular bodies do not need to have the intensity of structural member.Therefore, consider that cost can use paper tube.

As shown in Figure 2, by the top and the bottom of this concrete flooring base 25, on one side or another side imbed metal knitted net sheet or similar item 27, can improve this concrete bond strength.Therefore improve overall strength, thereby can reduce that part of concrete thickness.

As shown in Figure 3, this concrete flooring base 25 is observed in segmentation, and it has an I shape structure as can be seen.Whole flooring base 25 can be regarded one as provides high-intensity continuous I shape structure.And owing to need not banket for 25 times at flooring base, ground line is concordant.As a result, concrete flooring base 25 itself is consolidation very, needn't worry and cave in.Therefore, the floor of building according to the inventive method can not only be applicable to ordinary residence and storehouse, also is applicable to the floor of factory, sports palace or the resemble construction thing of a bearing load.Owing to need not worry depression, then will not fix with foundation wall 13 by concrete flooring base 25.Therefore, as shown in Figure 1, can lay isolated part 23, so just complete and outdoor isolation of this floor along foundation wall 13 whole height.Therefore, heat can not diffuse out by concrete flooring base 25 and foundation wall 13, can prevent that also moisture from entering from the outside.So it is very desirable that the floor of building with method of the present invention is used for floor heating.In method of the present invention, tubular body is arranged in parallel in the foundation wall institute area surrounded of a building, with the outer surface cast of concrete around these tubuloses, superior workability is provided, needn't use in the base as banketing, tamp and similar complicated construction, and use seldom that concrete can form a concrete flooring base consolidation, firm.Because do not need the intensity of tubular body, both having made is that paper tube is also applicable, so the use of pipe does not increase cost.

In addition, overcome resemble the depression the sort of problem relevant with conventional method, make a kind of heat insualting building become possibility, and obtained a kind of superior isolation effect.
