Description

The present disclosure relates to a wall construction and a building having such a wall construction. The invention relates to a method for constructing a building, as defined by claims 1 and 2. Methods for constructing a building are known in the art. Document US4532745 discloses a method for constructing a wall for a building, where building blocks with preformed through holes are placed on a base with anchoring means. Reinforcing means are placed in the preformed through holes, which are then filled with a curable construction material.
Another example follows from NL 1008128 , which describes a method wherein prefabricated EPS (expanded polystyrene) building blocks are placed on a foundation and glued together. Said building blocks are provided with through holes. The holes in the stacked-together building blocks must be positioned in line with each other. After a wall has been formed from said building blocks, a curable material is introduced into the holes and allowed to cure. The columns thus formed of the curable material impart strength to the wall, so that a support structure is obtained.
This known technique has the advantage that the building blocks must be stacked together in carefully aligned relationship upon construction of the building. Furthermore, separate building blocks must be produced for the positions where a window opening, a door opening or the like is planned. This leads to high costs and a difficult construction process.
Another drawback is that the strength provided by the columns is limited. It is therefore impossible, or very difficult, to construct a building in which the support structure of the building is solely made up of the columns.
The object of the invention is to provide an improved method in which the above drawbacks hardly occur, if at all.
The object of the invention is in particular to provide a method that can be carried out in a simpler and more flexible way and at lower cost than the known methods. The term "flexible" as used herein is understood to mean that it is readily possible to make modifications to a basic design of the building both during the design stage and during the construction stage.
Another aspect of this disclosure is to provide a building that can be constructed at lower cost than the buildings constructed so far. This disclosure also has for its object to provide a building whose design can be changed even during or after the construction stage.
In addition to that it is an aspect of the present disclosure to provide a method (not claimed) in which the logistics concerning the construction materials to and at the building site are simpler.
At least one of the above objects is achieved with the wall construction according to the present disclosure. Said wall construction comprises a wall, which wall is provided with a multitude of building blocks stacked together on a base, through which multitude of building blocks a through hole extends from a bottom surface of the wall up to a top surface of the wall. The wall construction further comprises anchoring means in the aforesaid base, which anchoring means extend from the base into the aforesaid through hole. The wall further comprises column reinforcing means placed in the through hole, which touch or nearly touch a part of the anchoring means that projects into said through hole. The column reinforcing means and the projecting part are interconnected in that the through hole is filled with a curable construction material for forming a reinforced supporting column that is attached to the anchoring means.
According to the present disclosure, a wall is thus provided which is strengthened by means of one or more supporting columns. The supporting columns are reinforced, the reinforcing means being connected to the projecting part of the anchoring means. Since the anchoring means are in turn anchored in the base, the bearing capacity of the supporting columns, and thus of the wall, is significantly increased. It is noted in this regard that within the context of the present invention a connection between the column reinforcing means and the anchoring means does not require that the two are actually connected together. Those skilled in the art will appreciate that even if a small distance exists between the two, the reinforcing effect of the column reinforcement and the anchorage on the supporting column will be hardly different than in the case of an actual connection.
The anchoring means comprise a screw anchor, for example, which is anchored in the base.
The base may comprise a foundation, with the anchoring means comprising reinforcing means placed in the foundation. The part of the anchoring means that projects into the through hole comprises a length of rebar forming part of the reinforcing means of the foundation.
The building blocks may be made of a thermally insulating material, such as expanded polystyrene (EPS) or polyurethane. Furthermore, the curable construction material may comprise cement, preferably concrete.
According to another aspect, the present disclosure provides a building comprising a multitude of wall constructions disposed adjacent to each other, which wall constructions are configured as defined above. Each wall construction is provided at the top surface thereof with a recess extending in a longitudinal direction of the wall, in which recess the through hole terminates.
The recesses in the top surfaces of the walls disposed adjacent to each other can form a closed channel, which is filled with a curable construction material for forming an integral construction of the supporting column or supporting columns in each wall, wherein the curable construction material filled in the channel is preferably identical to the curable construction material filled in the through hole of the wall constructions. As a result, walls disposed adjacent to each other, and in particular the supporting column(s) in said walls, are interconnected by means of the beam-like structure formed in the closed channel.
According to another aspect, the invention provides a method for constructing a building, as defined by the subject-matter of claim 1. In the method according to claim 1, the column reinforcing means are connected to anchoring means already provided for forming the wall, such as a length of rebar or a screw anchor. It is also possible, however, to realise such anchorage after at least a number of the building blocks have been placed.
The invention to that end provides a method for constructing a building, as defined by the subject-matter of claim 2. In said latter method, the anchoring means are preferably provided through the first opening after the placement of only the first building block. This does not exclude that such anchoring means are not provided until further building blocks have been placed as well. Furthermore, the anchoring means are preferably provided prior to the placement of the column reinforcing means.
The anchoring means may comprise a screw anchor which is or will be anchored in the base.
According to another possibility, the base comprises a foundation and the anchoring means comprise reinforcing means placed in the foundation. The outwardly projecting part of the anchoring means in that case comprises a length of rebar forming part of the foundation reinforcing means.
In both methods it is possible to provide the through hole in that the first building block and the further building blocks placed thereon, or some of said blocks, are provided with prefabricated openings. According to another possibility, however, the forming of the through hole takes place after the placement of the further building blocks. Mixed forms are not excluded. According to the invention, the forming of the through hole comprises the forming of openings contiguous to each other in the further building blocks. This is achieved by moving a heating element or a cutting or drilling element down from the upper side. The first opening extends through the first building block, with the first opening and the openings arranged contiguous to each other jointly forming the through hole. It is also possible, however, for the first opening to comprise a blind bore. In that case the forming of the through hole comprises the provision of openings contiguous to each other in the further building blocks and the first building block up to the aforesaid blind form so as to form the through hole.
The above methods have the advantage that the supporting columns can be provided at any desired position, depending on the building's design. The columns need not be provided with a fixed spacing between them, but only at those positions where they are needed so as to impart a required strength. If a single-storey building is constructed, fewer or thinner supporting columns can be used than in cases in which a multi-storeyed building is constructed and in which the supporting columns in the walls of the lowermost storey must in any case support one or more further storeys. Furthermore, a smaller number of relatively thick supporting columns may be provided instead of a larger number of relatively thinner supporting columns.
The building blocks can be placed on the foundation just like that, there being no need to take into account an accurate alignment of the building blocks. The method according to the invention can thus be carried out more quickly and at lower cost. Also the fact that according to the invention building blocks having a simple shape are always used leads to a method in which inexpensive building materials can be used.
It is in particular preferable if the wall is provided with: - a bottom surface abutting the foundation or the base, - main surfaces located opposite each other and facing away from the bottom surface and from the foundation, and - a top surface located opposite the bottom surface, which joins the main surfaces, and wherein the through hole extends from the bottom surface to the top surface or to a part of one of the main surfaces that is located near the top surface. In this way a method is provided by means of which strong supporting columns can be obtained, whilst the method can nevertheless be carried out in a very flexible manner.
It is furthermore preferable if a longitudinal direction of the wall extends in a direction parallel to the main surfaces and the bottom surface, and wherein the method also comprises the step of forming a recess extending in a longitudinal direction of the wall in the top surface, wherein at least some of the through holes formed terminate in the recess. In said recess, a beam can be formed by filling the recess with concrete, preferably with reinforcing means provided therein. Reinforcing means provided in the supporting columns will preferably be connected to the reinforcing means in the beam. The supporting columns thus form a strong support structure which is supported on the foundation or on the base and which is also connected to the beam at the upper side of the wall. Such a structure is suitable for serving as a support unit for a roof structure or a higher building level. In particular if the beam extends over the entire wall, with the wall extending as a continuous wall of the building, a ring beam is formed which imparts greater strength to the building. It is even possible to form two or even more, for example substantially parallel, beams or ring beams.
The ring beam may be thicker (higher and/or wider) at a position where fewer supporting columns are provided or where a greater load is applied to the ring beam. The recess that is formed in the top surface of the wall can in that case be made deeper, with a correspondingly larger amount of reinforcing means, so that a greater strength is obtained and a greater load can be taken up.
Because the recess for the beam, for example the ring beam, is formed in the wall and the wall functions as a mould, remaining present after the curing of the concrete, the beam can be configured as a conical beam having a wider bottom side and a narrower upper side. This leads to a beam having a greater deflection resistance, using a smaller amount of concrete, than a purely rectangular beam.
The invention also relates to a method comprising the step of placing reinforcing means in the recess, - connecting the reinforcing means in the recess to the reinforcing means in the through holes, - introducing a curable construction material into the recess, and - allowing the curable construction material to pure so as to form a beam, preferably a ring beam. The reinforcing means in the beam impart additional strength to the construction of the building.
The filling of the curable construction material in the recess and the filling of the curable construction material in the through hole can essentially take place in one operation.
In addition to that, the invention relates to a method wherein at least one of the through holes extends at an angle deviating from 90° in the longitudinal direction of the wall, preferably at an angle of 40° to 85° with respect to the horizontal, more preferably an angle of 45° to 75°. As a result, at least one support column is inclined in the longitudinal direction of the wall. The cross bonds that are necessary when only vertical supporting columns are used are thus not needed.
The invention further relates to an embodiment wherein a first part of the through holes extends from the recess in the top surface to a position of the bottom surface relatively close to a first main surface, and a second part of the through holes extends from the ring beam to a position of the bottom surface relatively close to a second main surface. As a result, not all the supporting columns are disposed vertically in the wall, but a first part of the columns, seen from the ring beam, will extend obliquely to a first main surface and a second part of the supporting columns will extend obliquely to a second main surface of the wall. Because of this, higher forces can be withstood than in the situation in which all the supporting columns extend vertically in the wall. It is possible in that case for some of the columns to extend at an angle, whilst other columns extend vertically. According to another possibility, all the columns are positioned at an angle. It may be advantageous, for example, to provide vertical columns on either side of a door opening or a window opening.
It is also preferable if the method also comprises the step of providing a through opening in the wall for forming a window opening, a door opening or similar opening. Said openings are formed after the wall has been constructed. Forming the openings only after the wall has been constructed provides the advantage that identical building blocks can be used for the entire wall, and consequently for the entire building. In this way errors in the work preparation are excluded. The method can thus be carried out with a greater degree of reliability and at lower cost.
In addition to that, the invention relates to an embodiment comprising the step of forming recesses in the wall, for example for placing conduits, mounting elements or finishing elements, such as conduits for electricity, water, gas and the like, therein and filling said recesses with a filling material after the placement of said conduits or mounting elements. The filling material may be the same material as the material from which the building blocks are made. The filling material may also be a similar material or a totally different material. One requirement that can be made of the filling material is that it bonds to or can be adhesively connected to the material of the building blocks. In particular, but not exclusively, PUR foam (a polyurethane substance) is a material that is suitable for this purpose.
The recesses they have a shape suitable for placing a finishing element such as a TV screen therein. The recess may also have a shape of a soap dispenser, a stair handrail, etc. Furthermore, a recess may be provided near a door opening on either side of the door hinge, in which recess the open door can be received. The open door will not take up any space outside the wall in that case.
Examples of various mounting elements that can be placed in the wall are mounting elements for mounting stair hand rails, soap dispensers, TV screens, monitors, lamps, doors, shower fittings, etc.
In order to obtain a strong wall surface whilst at the same time improving the overall structural strength of the wall, it is preferable if the method comprises a step of fixing a reinforcing mesh to the wall and providing a finishing layer on top thereof. The finishing layer is preferably capable of taking up pressure forces and tensile forces; it may for example, but not exclusively, be a layer plastered or sprayed thereon. The reinforcing mesh will preferably be provided after the conduits have been placed in the wall and the recesses formed have been filled. The reinforcing meshes on the either side of the wall may for example be connected together by means of tie-rods. By providing the tie-rods under tension, the wall is fixed against the columns, as a result of which the stiffness of the wall will increase significantly.
With a view to finishing a building so that it is ready to use, the method comprises the step of providing a roof and connecting structural members of the roof to structural members provided in the ring beam. The roof may comprise bearing girders, for example, which are attached to the ring beam by means of structural members. The structural members may consist of a joist anchor or the like. The roof, or the bearing girders of the roof, can be supported on the ring beam or be suspended from the ring beam.
A very advantageous embodiment is obtained if the roof is covered with photovoltaic panels. This has the advantage that the building can be self-supporting, in particular also because the EPS is a very good thermal insulator. The heating costs in the winter will be very low in that case, whilst in the summer the building will keep out the heat well. In addition, EPS is a very inexpensive material which is suitable, using the method according to the invention, for use in parts that are used as bearing parts in traditional construction. EPS is generally available in a flame-retardant form. The roof may for example be lined with insulating boards, for example made of EPS or another insulating material, such as polyurethane, glass wool, rock wool or the like. The roof timbers may be covered with roof sheathing, for example, and boards made of EPS (or another material as mentioned above) can be placed between the roof timbers. Conduits, for example for electricity, can be passed through the EPS boards, whereupon finishing panels, such as plaster boards, can be used for covering the beams and the EPS boards.
In order to be able to construct the building suitable for use, using the method according to the invention, one embodiment preferably also comprises the step of installing a floor in the building, comprising the steps of: - placing insulating floor elements between the walls of the building, - forming recesses extending between two walls in the floor elements, - placing reinforcing means in said recesses, - placing the reinforcing means in the recesses into contact or close proximity with the foundation or with the reinforcing means present in the foundation, such as lengths of rebar, or with anchoring means in the base, - filling the recesses with a curable construction material, and - allowing the curable construction material to cure. The recesses in the floor elements in that case form reinforced and bearing floor joists. In a corresponding manner it is possible to use a reinforced concrete type which contains fibres and which is used in place of the combination of concrete and reinforcing means provided in advance. The invention in that case relates to a method comprising the installation of a floor in the building, which installation comprises the steps of: - placing insulating floor elements between the walls of the building, - forming recesses extending between two walls in the floor elements, - filling the recesses with a reinforced concrete type and placing the concrete into contact with the foundation or with reinforcing means in the foundation, such as lengths of rebar, or with anchoring means in the base, and - allowing the concrete to cure.
It is in particular preferable if the building blocks, and preferably also the floor elements, are made of expanded polystyrene. In this way a wall having a high thermal insulation value can be obtained, in which openings can be readily provided for forming the supporting columns. Also other thermally insulating materials such as polyurethane, for example, or the like can be suitably used as long as it can be easily worked for forming an opening therein for the purpose of forming a supporting column.
The invention provides the major advantage that no substances and materials that are foreign to the construction industry need to be used, so that no tests for new materials are needed.
The invention will now be explained in more detail with reference to a drawing. In the drawing:

Fig. 1 shows a wall built in accordance with the present invention;
Fig. 2 is a schematic representation of a building constructed in accordance with the present invention; and
Fig. 3 is a schematic representation of a wall according to the invention.

In the figures, like parts are indicated by the same numerals. However, for the sake of simplicity not all the parts required for a practical implementation of the invention are shown.
Figure 1 is a schematic representation of a part of a wall 1, which is built up of individual building blocks 2, 2' in the illustrated embodiment. The wall 1 is not completely finished, but shown in partially completed condition in the figure. The building blocks 2 used in this embodiment have a dimension of about 50 x 100 x 200 cm (thickness D x height H x length L). Other dimensions may be used without any restriction, of course, providing they are suitable for use in the construction of a building. In the stacking arrangement shown in figure 1, the thickness D of the wall is 50 cm. The building block 2' as shown in figure 1 is cut through halfway its length, so that a stretcher bond is obtained. The building blocks are glued together so as to obtain sufficient strength. A lowermost row of building blocks 2 is placed on a foundation 3 and preferably attached thereto, for example by glueing, using PUR foam, for example. Said lowermost row of building blocks 2 may be provided with an opening that is arranged over lengths of rebar projecting from the foundation or through which a screw anchor is anchored in the base. In the latter case, a flat recessed base instead of a poured foundation will in many cases suffice. The anchorage provides an adequate hold for providing a support structure for the building. In this way a relatively simple and economical construction method can be obtained.
The wall 1 has a bottom surface that is placed on the foundation 3. The wall 1 further has two main surfaces 9, 10 located opposite each other (only the surface 9 is shown in Fig. 1), and a top surface 11. Once a wall 1 is completely built up, a chase 6 is formed in the top surface 11. In the illustrated embodiment, said chase 6 is formed along the entire length of the wall 1. In said chase, openings 4, 4', 4'' are formed in the wall 1. As is shown in Fig. 1, the openings 4, 4', 4" can be formed from the chase 6 up to the foundation 3. Subsequently, reinforcing means can be provided in the openings 4, 4', 4", whereupon concrete is poured into the opening 4, 4', 4'', which concrete is subsequently allowed to cure. In this way supporting columns 12, 12', 12'' (refer to Fig. 2 in this connection). Said concrete will also fill the chase 6, which is provided with reinforcing means 11, thereby forming a ring beam 8 disposed in the top surface 11 of the wall. The reinforcing means 5 are preferably connected to the foundation 3 or, more preferably, to reinforcing means in the foundation, such as a length of rebar (not shown), which leads to a very strong connection of the supporting columns formed in the openings 4, 4', 4''. The openings 4, 4', 4" may be provided in vertical direction, as represented as the opening 4. According to a preferred embodiment, at least some of the openings 4, 4', 4" are formed at an oblique angle in the wall, as is represented for the openings 4', 4". The openings 4, 4', 4" all terminate in the chase 6 at the top surface 11, making it possible to connect the reinforcing means 5 to the reinforcing means 7 in the chase 6. In this way a great strength of the support structure formed by the foundation 3, the supporting columns 12, 12', 12'' and the ring beam 8 is obtained.
Fig. 3 shows a variant thereof, in which the column 12' is disposed at an angle, seen in the longitudinal direction of the wall 1. This is done to compensate for the cross bonds that are missing in the illustrated embodiment, which cross bonds are necessary if all the supporting columns 12 are disposed vertically.
A mesh structure 13 is provided on the main surfaces 9, 10 of the wall 1. Said mesh structure is known in the art, it imparts strength to the wall 1. Preferably, the mesh structures on the two surfaces 9, 10 are connected by means of tie-rods. This provides a solid fixation of the mesh structures and sets up a tensile force on the wall surfaces, so that the wall will have a greater strength. In fact, the wall construction obtained in this manner can be compared to a sandwich construction. On the mesh structure, a plaster layer may be provided as a finishing layer.
Fig. 2 is a schematic view of a building constructed by using the method according to the invention. The building comprises walls 1. Said walls are only partially shown. A number of supporting columns 12 are shown, whilst the enveloping wall 1 and the foundation 3 have been left out at the location of the supporting columns 12 so as to illustrate the invention more clearly. In the embodiment shown in Fig. 2, all the supporting columns 12 are disposed vertically. A window opening 14 is schematically indicated between two supporting columns 12. Said window opening 14 can be formed after the entire wall 1 has been constructed. Upon construction of the wall 1, a closed wall circumference of the building is constructed, after which openings 14 for windows and doors are formed.
Said operations are easy to carry out in particular if the walls 1 are formed of expanded polystyrene.
Fig. 3 shows an alternative embodiment of the wall 1, in which part of the mesh structure 13 on the wall 1 has been left out. The surface 15 of the building block 2 is clearly shown therein.
Another major advantage is the fact that the method is suitable for expanding the polystyrene at the building site, because a simple device that produces building blocks in just one form suffices for constructing a building.
The invention is not limited to the embodiments described above and shown in the figures. The invention is instead defined by the appended claims.
