Description

Building element for insulating and/or reinforcing an exterior wall of a building Field of the invention
The invention relates to a building element for insulating and/or reinforcing an exterior wall of a building, comprising: a bottom surface, a top surface positioned at a distance from the bottom surface, a first pair of opposite side surfaces, spaced-apart in a length direction, a second pair of opposite side surfaces, spaced-apart in a width direction, connecting the first pair of side surfaces, wherein the first and second pairs of side surfaces connect the top surface and the bottom surface, and a through-hole extending substantially vertically from the top surface to the bottom surface, the through-hole having a circumferential surface being substantially impermeable to fluid concrete to be poured into the through-hole.
Background of the invention
During the lifetime of a building, the exterior walls thereof can lose their strength, stability and insulative properties for a variety of reasons, such as earthquakes, erosion due to extreme temperature variations, precipitation, et cetera.
In practice, it often proves difficult to repair such an exterior wall, in particular when major cracks or generally major structural damage is present. The building may even become eligible for being torn down completely.
Various attempts have been made to reinforce and/or insulate the exterior wall by means of an auxiliary wall, but these attempts thus far have only provided mediocre results.
The inventor for instance tried to use the building elements according to NL 2009796 to build an auxiliary wall with the desired properties. However, problems with stability and insulation still remained.
It is therefore an object of the invention to provide a means of reinforcing and/or insulating an exterior wall of a building, by means of an auxiliary wall, wherein a satisfactory and durable result is obtained, preferably by using building elements similar to the ones disclosed in NL2009796.
Summary of the invention
Hereto, according to the invention, the building element for insulating and/or reinforcing an exterior wall of a building is characterized in that the through-hole comprises a sideways opening to one of the opposite side surfaces of the second pair of opposite side surfaces, the one side surface being configured to contact an outer wall surface of the exterior wall, wherein, during use, the sideways opening is configured to be closed off by the outer wall surface of the exterior wall, such that the fluid concrete poured into the through-hole is prevented from flowing out of the sideways opening by the exterior wall and, after the fluid concrete has dried, the exterior wall is connected with the concrete column in sideways direction.
The inventor has found that the above building element can be used to form an auxiliary wall sufficiently strong and having sufficient insulative properties to improve even heavily damaged exterior building walls, i.e. exterior walls having major cracks and structural damage.
In principle, the above building element can also be used without using concrete columns for additional support (i.e. the through-hole is discarded), in particular when damage is non-existent or minor and only improved insulative properties are sought after. The building elements can then be stacked onto each other and/or glued to the exterior wall by using a mortar or the like.
An embodiment relates to an aforementioned building element, wherein the sideways opening extends vertically along the through-hole from the top surface to the bottom surface such that a continuous contact surface of the concrete column with the exterior wall is obtained.
An embodiment relates to an aforementioned building element, comprising expanded polystyrene (EPS). EPS is relatively light and has very good insulative properties. EPS has good insulation properties, with respect to sound insulation as well as thermal insulation and, in most countries, can be produced locally. Furthermore, it has low density thus decreasing the weight of the final structure. Another advantage is that the EPS used is fire/flame retardant. A yet further advantage is that EPS is not susceptible to rot or problems relating to fungus deposits. Preferably, the EPS has a volumetric mass of 20 kg/m3. More preferably, the heat conduction coefficient is about 0,038 W/m.K. Even more preferably, the compressive strength/stiffness is about 100 kPa at a deformation of 10%. Most preferably, the EPS also has a deflective strength of 150 kPa. Other light-weight materials can, however, also be used, especially materials having a relatively low density of for instance lower than 50 kg/m3, such a lower than 40 kg/m3, more preferably lower than 30 kg/m3, most preferably 20 kg/m3 or lower.
An embodiment relates to an aforementioned building element, wherein the second pair of opposite side surfaces are spaced-apart in width direction at a distance (W) of 75 - 300 mm. Applicant found that in particular when EPS is used, sufficient insulation can be obtained in most cases.
An embodiment relates to an aforementioned building element, wherein the distance (W) is 175 - 225 mm, preferably around 200 mm. Applicant has found that in particular when EPS is used insulative values of 5,15 < Rc < 6,62 can be obtained, which means that sufficient insulation is provided for improving the majority of buildings built in the Netherlands.
An embodiment relates to an aforementioned building element, wherein the one side surface is provided with a ripple pattern to improve adhesion of the one side to the exterior wall in case a layer of mortar is applied there between.
Another aspect of the invention concerns a reinforced wall structure comprising an exterior wall of a building and an auxiliary wall comprising two or more aforementioned building elements, wherein the bottom surface of one building element is placed on the top surface of another building element in such a way that the through-hole of the one building element is aligned with the through-hole of the other building element, thereby forming a continuous through-hole, the one side surface contacting the outer wall surface, wherein the sideways openings are closed off by the outer wall surface of the exterior wall, such that the fluid concrete poured into the continuous through-hole is prevented from flowing out of the sideways openings by the exterior wall and, after the fluid concrete has dried, the exterior wall is connected with the concrete column in sideways direction.
An embodiment relates to an aforementioned reinforced wall structure, wherein the continuous through-hole is filled with concrete forming a concrete column vertically extending through the building elements.
An embodiment relates to an aforementioned reinforced wall structure, wherein the concrete column comprises reinforcement in longitudinal direction of the concrete column.
An embodiment relates to an aforementioned reinforced wall structure, wherein the concrete column is provided with one or more anchorings projecting transversely from the concrete column and connecting to the exterior wall. In case reinforcement in longitudinal direction is used, the anchorings can be connected to the reinforcement prior to the concrete pouring step.
Another aspect of the invention relates to a method for insulating and/or reinforcing an exterior wall of a building by using one or more aforementioned building elements to form an auxiliary wall, the exterior wall being supported on a foundation and having an inner and outer wall surface, comprising the following steps: placing the bottom surface of one building element on the top surface of another building element, wherein the one building element and the another building element are positioned to form the auxiliary wall along the outer wall surface of the exterior wall with the opposite side of the second pair of opposite side surfaces comprising the sideways opening contacting the outer wall surface, aligning the through-hole of the one building element with the through-hole of the other building element, thereby forming a continuous through-hole, wherein the sideways openings are closed off by the outer wall surface of the exterior wall, repeating the previous steps until the desired auxiliary wall height is achieved, filling the continuous through-hole with concrete such that a concrete column is formed, wherein the fluid concrete is prevented from flowing out of the sideways openings by the exterior wall, and allowing the concrete to dry, such that the exterior wall is connected with the concrete column in sideways direction.
An embodiment relates to an aforementioned method, furthermore comprising the step of inserting reinforcement into the continuous through-hole in the longitudinal direction of the continuous through-hole before filling the continuous through-hole with concrete, and/or connecting the aforementioned anchorings therewith, if applicable.
An embodiment relates to an aforementioned method, comprising applying a layer of mortar between the outer surface of the exterior wall and the one side surface of the building element to further improve the connection of the building elements with the exterior wall.
Preferably, the building element has a brick-like shape. These brick-like building elements are cheap to manufacture and easy to stack. The through-hole preferably has a substantially circular cross-section.
An embodiment relates to an aforementioned building element, wherein the top surface is provided with one or more rows of protrusions extending along the intersection of the top surface and the second pair of side surfaces for connecting to one or more corresponding rows of recesses comprised by a bottom surface of a further building element to be placed on top of the building element. Thus, accurate positioning can be achieved, especially for creating a proper fluid-tight fluid connection at the upper surface of the building element.
Further advantageous embodiments can be based on the subject-matter as disclosed in Dutch patent application NL 2013089 by the present Applicant, which subject-matter is herewith incorporated into the present application by reference.
Brief description of the drawings
Embodiments of a reinforced wall structure comprising building elements according to the invention will by way of non-limiting example be described in detail with reference to the accompanying drawings. In the drawings:
Figure 1 shows a perspective view of an embodiment of a reinforced wall structure comprising building elements according to the invention; and
Figure 2 shows a cross-sectional view of the embodiment of the reinforced wall structure according to figure 1.
Detailed description of the invention
Figure 1 shows an embodiment of a reinforced wall structure 5 with an exterior wall 1 of a building and an auxiliary wall 6 comprising building elements 7 according to the invention. Figure 1 shows a perspective, cut-away view of the reinforced wall structure 5. The embodiment of the building element according to the invention is denoted by reference numeral 7 in figures 1-7. Figure 2 shows a cross-sectional view of the embodiment of the reinforced wall structure 5 according to figure 1. Figures 1 and 2 will be discussed in conjunction.
The building elements 7 are arranged in layers, staggered along by half the length L of a building element 7. The length of a typical building element 7 as shown is for instance 1-2 m, whereas the typical height H is 250 - 1000 mm and the typical width W 75-300 mm, preferably 175-225 mm, more preferably around 200 mm. The building elements 7 as shown each comprise a bottom surface 18, a parallel top surface 17 and four side surfaces, of which two side surfaces are longitudinal side surfaces 21 and two side surfaces are transversal side surfaces 19. Each building element 7 as shown is provided with two through-holes 10 having a (semi-)cylindrical shape. The inner circumferential wall 20 of a through-hole 10 forms an outer surface of a respective building element 7. The building element 7 preferably comprises expanded polystyrene (EPS), such as EPS BioFoam®, or a similar light-weight material having a relatively low density. The through-holes 10 of the building elements 7 in the different layers are aligned to form single, continuous through-holes 16. In each continuous through-hole 16 a concrete column 13 is present. The concrete columns 13 are reinforced with reinforcement rods 11. However, the skilled person will understand that other types of concrete, especially reinforced concrete with different types of reinforcement, are also conceivable.
According to the invention, the through-hole 10 comprises a sideways opening 27 to one 3 of the opposite side surfaces 21 of the second pair of opposite side surfaces, the one side surface 3 being configured to contact an outer wall surface 2 of the exterior wall 1, wherein, during use, the sideways opening 27 is configured to be closed off by the outer wall surface 2 of the exterior wall 1. Preferably, the sideways opening 27 extends in a direction perpendicular to the one side surface 3. More preferably, the sideways opening 27 is formed by the one side surface 3 intersecting the through-hole 10, such that a frusto-circular or semicircular cross-section of the through-hole 10 is obtained. Thus, fluid concrete poured into the through-hole 10 is prevented from flowing out of the sideways opening 27 by the exterior wall 1 and, after the fluid concrete has dried, the exterior wall 1 is connected with the concrete column 13 in sideways direction, providing exceptional structural reinforcement to the exterior wall 1. Preferably, the sideways opening 27 extends vertically along the through-hole 10 from the top surface 17 to the bottom surface 18.
To facilitate adhesion/contact between the building element 7 and the exterior wall 1 a layer of mortar 22 may be applied between the outer surface 2 of the exterior wall and the one side surface 3 of the building element 7. To even further improve adhesion the one side surface 3 can be provided with a ripple pattern 4.
Furthermore, the building elements 7 are provided with a row of protrusions 12 on their top surfaces 17, these protrusions 12 being designed for engaging recesses of building elements 7 in the layer above the layer in which the respective building element 7 is arranged.
The through-holes 10 have a circumferential surface 20 being substantially impermeable to fluid concrete to be poured into the through-hole 10. Preferably, the concrete column 13 comprises reinforcement cables or wires 11 in longitudinal direction, such as 1-3, for instance 1 or 2.
The top surface 17 is provided with a raised part 25. The bottom surface 18 is provided with a corresponding groove. When placing one building element 7 on top of another building element 7, the raised part/groove 25 construction significantly simplifies positioning. Analogously, the transversal side surfaces 19 may be provided with a vertical groove, or a pair of vertical grooves, wherein an adjacent building element is provided with a corresponding elongated protrusion.
The concrete column 13 as shown is provided with anchorings 8 projecting transversely from the concrete column 13 (preferably connecting to any reinforcement arranged therein) and connecting to the exterior wall 1.
If required, one or more intermediate layers of building elements 7 can comprise a horizontal row of special building elements 7 that have a relatively small width W as to form a horizontal space between the exterior wall 1 and that respective building element 7. The space runs in the length direction X and is fluidly connected to the through-holes 10, such that when concrete is poured into the through-holes 10, the space is filled with concrete and a horizontal beam 26 is formed to provide additional structural strength. Again, the space can be provided with reinforcement to obtain a reinforced concrete beam 26. Preferably, such a beam 26 is formed at a height corresponding to the position of a floor.
Thus, the invention has been described by reference to the embodiments discussed above. It will be recognized that the embodiments are susceptible to various modifications and alternative forms well known to those of skill in the art without departing from the spirit and scope of the invention. Accordingly, although specific embodiments have been described, these are examples only and are not limiting upon the scope of the invention.
