Description

INDUSTRIALIZED CONSTRUCTION PROCEDURE OF PREFABRICATED BUILDINGS AND SETS FOR USE IN THIS

PROCESS

OBJECT OF THE INVENTION

The present invention relates to a process industrialized building construction in which prefabricated assemblies comprising a plurality of simpler pieces which are filled subsequently with a binding material and / or binder.

BACKGROUND OF THE INVENTION

In the technical construction sector they are known building procedures in which they are used prefabricated assemblies in order to industrialize, by less partially, the building process, simplify assembly tasks and / or reduce the time of building.

Thus, for example, document US 4,513,545, in the name by George D. Hopkins Jr., discloses a procedure of construction that contemplates prefabricating a plurality of construction modules equipped with four walls and join them later with each other by stacking and / or by fitting a plurality of joists into spaces voids provided for this purpose.

This procedure uses modules of solid construction, so it does not contemplate the use of no binding material and / or binder, or No formwork structure lost. In addition, it does not exist no element arranged continuously along the different modules that make up the building, which prevents said building from having a character monolithic.

On the other hand, in the state of the art also they know building procedures that contemplate fill structures with a binder material, such and as disclosed, for example, in US 6,085,476 on behalf of David B. Jantzi and Cols.

However, to

difference from documents from the

technique

previous cited, the  invention proposes a

process

industrialized from building from

buildings in which, simultaneously:

-Prefabricated assemblies are used that comprise hollow section pieces;

-These prefabricated assemblies are joined later each other to form formwork structures lost;

-These substantially hollow regions are filled subsequently with a binding material and / or binder;

-This industrialized procedure makes it possible build monolithic buildings whose

solidity and resistance to loads is comparable to the of a conventional building; Y

-These buildings are also provided technically equivalent and aesthetically members similar to beams, pillars, walls, floors, slabs and / or stairs of a conventional building.

SUMMARY OF THE INVENTION

A first aspect of the invention relates to a industrialized construction procedure of buildings other than those known in the state of the technique that also addresses the following issues:

-

 What makes it possible to build design buildings

-

 That said prefabricated assemblies are also substantially light and transportable (according to usual criteria of the technical sector of the construction) and at the same time confer on the building, once it is finished, a monolithic character, solidity and resistance to loads comparable to those of a building conventional and provide for said member building technically equivalent and aesthetically similar to beams, pillars, walls, floors, slabs and stairs of a conventional building.

Prefabricated assemblies for use in the procedure according to the invention they are formed by a plurality of hollow section pieces, also being placed on said parts all installations, coatings and finishes of the building. Also, said prefabricated assemblies are designed in such a way that specific portions of the hollow sections of said pieces are coincident and, by joining together, they form a unique empty space and substantially continuous.

Once these prefabricated assemblies have been transported to its final location, they join each other to form a structure that will be used as lost formwork. Subsequently, the sets prefabricated are filled with a binder material and / or binder. Thanks to the special configuration of the hollow section pieces (described above), said binder and / or binder material can flow without interruption of some prefabricated assemblies to others, completely filling in the continuous empty space to reproduce technically equivalent members to the beams, pillars, walls, floors, slabs and stairs of a conventional building.

Thus, the binder material and / or binder is finally arranged continuously to throughout the space substantially bounded by the pieces of the different prefabricated assemblies, what which gives the building, after the setting of the binder and / or binder material, a character monolithic.

On the other hand, some pieces may also be provided with distribution holes to facilitate the binder and / or binder material is distributed evenly throughout the empty space. Likewise, they can also be provided with holes that allow passage of rebar.

More particularly, the industrialized procedure of construction of buildings according to the invention comprises the following stages, not necessarily consecutive:

a) Provide the layout, characteristics General and technical requirements of the building to build;

b) Industrially manufacture a plurality of transportable assemblies comprising parts of hollow section, being specific portions of said substantially hollow sections coinciding with each other, so that by joining those pieces form a unique empty space, substantially continuous, and when filling said space with a binding material and / or binder, the combination of said pieces and said binder and / or binder material form technically equivalent members and aesthetically similar to beams, pillars, walls, floors, slabs and if they are present, stairs, from the building to be built, also placing on these pieces the installations, coatings and finishes of building;

c) Transport these sets to their definitive location;

d) Build the foundation of the building;

e) Place the assemblies on the foundation corresponding to the first floor of the building, leveling and joining them together;

F)

g) Once the binder material and / or binder has acquired a resistance of work, place the corresponding sets to the next floor of the building, level them and join them together;

h) Fill in the hollow regions of said assemblies with the binder and / or binder material, following a procedure substantially identical to that of stage g;

i) Repeat steps g) and h) as necessary.

The work resistance of the binder material and / or binder mentioned in step g) is therefore enough strength for the material binder and / or binder substantially maintain its structural integrity by continuing building on the plant on which such binder material is arranged and / or binder. How will the person skilled in the art understand

the light of the teachings of this document, the value of the work resistance depends on the parameters of each embodiment, such as material composition binder and / or binder, development point of the setting of such binder and / or binder material, loads to be borne by such binding material and / or

binder,

etc., Y may be calculated for every

realization

by he expert  in the technique using

known procedures

A second aspect of the invention is to propose a plurality of prefabricated assemblies for use in the industrialized construction procedure of buildings described above. Such sets Prefabricated are formed by hollow section pieces, said pieces being of various types.

Thus, in the present specification, the pieces more simple they are called “elements”. These elements are combine in turn with each other to form more complex pieces which, in the present specification, are called "Components." Finally, the components are combined each other to form each of the transportable parts which, according to the method of the invention, comprises the building and that in the present specification they call either "fractions" or "sets" prefabricated

Therefore, both the components and the elements to from which said components are formed, manufactured with dimensions according to the dimensions specific to the fraction of which they are part and / or the specific dimensions of adjoining fractions.

There are four different groups of components: linear, surface, ladder and components auxiliary

The group of linear components includes: abutment components, lower beam components and the upper beam components.

The group of surface components includes: the technical floor components, the wall components, , and forged components.

The group of auxiliary components includes all

the

components from Connection to the foundation,

the

DETAILED DESCRIPTION OF THE INVENTION

Figures 1A, 1B, 1C and 1D are shown respectively, the north, east, south and west elevations of a example of a possible building E to build.

This building E has a distribution markedly asymmetric and allows to illustrate the great variety

from

buildings that they can  build up according he

process

Y  the sets prefabricated  from the

invention.

In Figure 1E, which represents a cross section of building E, it is shown that said building E it consists of a foundation plant, a ground floor, a upstairs and a roofing plant, which will be described in more detail in Figures 2A, 2B, 2C and 2D, respectively.

In this specific embodiment, both the ground floor like the top floor of building E have two portions that are high with respect to the rest of the plant, so that the distribution of said

building E is irregular and has the following characteristic heights:

H0: height from which the plant extends of foundation; H1: height from which the plant extends  low; H2 height from which the portion extends raised from the ground floor; H3: height from which the plant extends  high; H4 height from which the portion extends raised upstairs; Y H5: height from which the plant extends  of covers;

Likewise, both in said figure 1E, and in others figures that will be described later, have been drawn dotted lines to help identify the different fractions that form building E.

The foundation plant is shown in Figure 2A corresponding to building E, as well as fractions prefabricated necessary to form said plant, according to a first embodiment of the process of the invention.

Throughout this description, the fractions Prefabricated are named using the letter F, followed by a number from 0 to 5 (corresponding to the height to the se assemble this fraction), and followed by a letter and number (which illustrates the position of the fraction within the corresponding plant).

To indicate the position of a fraction within a plant is also used, in the present description, a coordinate system based on rows and columns. The rows are named correlatively, from top to bottom, starting with the letter A. The columns, in turn, are number consecutively from left to right.

Thus, the foundation plant shown in the Figure 2A is formed, according to a first embodiment of the method of the invention, from the union of a fraction F0A1 arranged in a top left position; a fraction F0B2 arranged in a lower position left; and a fraction F0B4 arranged in a position lower right.

The ground floor shown in Figure 2B comprises a bathroom B, a hall V, a dining room S, and a porch P. Said ground floor is formed, according to the present realization of the process of the invention, from the union of fractions F1A1, F1B2, F1B4 and F1C2.

Also, the top floor shown in Figure 2C it comprises a bedroom, D provided with a balcony and some Access stairs to the lower floor. That high floor it is formed, according to the present embodiment of the process of the invention, from the union of the fractions F3A1, F3A2, F3A3, F2C2 and F3B3.

Finally, the roofing plant shown in the Figure 2D is formed, according to the present embodiment of the method of the invention, from the union of the fractions F5A2 and F4C2.

Figure 3 is an exploded cross section and schematic of the building E. In it, you can see the cross sections of fractions F0B2, F0A1, F1C2, F1B2, F1A1, F2C2, F3A2, F4C2 and F5A2.

Figure 4 is an axonometric perspective view. which shows the position they occupy, after installation, the prefabricated fractions F0A1, F0B2, F0B4, F1A1, F1B2, F1C2, F1B4, F3A1, F3A2, F3A3, F2C2, F3B3, F5A2 and F4C2, necessary to build the building E, according to the present embodiment of the process of the invention.

In said figure 4 and in other subsequent figures have omitted the portions of installations, coatings and finishes provided in prefabricated fractions, as well as some of the wall components provided in part of these fractions, so that you can better appreciate the inside of said fractions.

Figures 5A to 5L are shown in perspective. axonometric each of said prefabricated fractions F0A1, F0B2, F0B4, F1A1, F1B2, F1C2, F1B4, F3A1, F3A2, F3A3, F2C2, F3B3, F5A2 and F4C2.

On the other hand, in the present embodiment of the method of the invention, each of the fractions prefabricated has a sufficient structure portion so that this fraction is self-supporting.

Also, in the present embodiment the parts that they form each fraction are standardized and can only have a set of dimensions

More particularly, said set of dimensions results from imposing that the dimensions in the vertical plane and horizontal of the pieces are integer multiples of some certain quantities that, in this embodiment, are:

-in the horizontal plane: 5 cm; Y

- in the vertical plane: 18 cm (it is determined that this also be the height of a riser).

These minimum dimensions are chosen because they Consider them anthropometric. Also, as in vertical sense only dimensions that are integer multiples of the height of a riser, this division guarantees that the stair sections coincide exactly with the upper limit of the fractions and not they remain, therefore, neither above nor below.

This embodiment of the method of the invention contemplates build each of the fractions into which it is divided the building through the union of a plurality of components, which are in turn made of more pieces simple, called elements, and formed in this embodiment from elongated laminar pieces that define regions hollow, more particularly, of galvanized steel profiles of standardized dimensions.

Figure 7A is a schematic sectional view. cross section of the land on which it will be built, which schematically shows the placement of three portions COA, COB, COC building foundation.

Figure 7B is a schematic sectional view. cross section showing the assembly of fractions F0B2 and F0A1 and F0B4 (not visible in the figure) to form, according to the present embodiment of the process of the invention, the foundation plant of building E.

Figure 7C is a schematic sectional view. cross section that shows how they are filled with a material binder and / or binder, according to the procedure of the

invention, the corresponding hollow regions of the fractions F0B2 and F0A1.

In this embodiment, the chosen binder material it is self-compacted concrete which, being very fluid, allows all regions to be filled in a homogeneous way hollow, provided for that purpose, in fractions. I dont know Use binder material.

However, it is possible to use any other binder and / or binder material that conforms to the specific requirements of the particular building a build.

Also, in this embodiment of the procedure of the invention, the pouring of the binder material is carried out according to the "inverted table" technique, that is, pouring this one from the top of the pillars of the fraction

or fractions to concrete, so that it falls by gravity to the bottom of the hollow regions of said fraction or fractions.

In figure 7C, as well as in all figures Subsequent, the hollow regions of the fractions filled with self-compacted concrete are marked with a pattern of oblique lines.

Figure 7D is a schematic sectional view. cross section showing the assembly of the F1C2 fractions, F1B2 and F1A1, from the ground floor on the floor of foundation. This stage of the process of the invention occurs once the concrete of the plant

foundation has acquired the work resistance to bear the weight of said fractions F1C2, F1B2 and F1A1.

As concrete does not acquire resistance linear, but that acquisition occurs very quickly at the beginning and later slows down, the lightness of fractions constructed according to procedure of the invention makes it possible for the fractions corresponding to a plant can be placed on the immediately lower floor without waiting for the concrete of said immediately lower floor has completely set.
