Definitions

  • a method for casting an insulated wall and a disposable formwork to be used for and an insulated body to be used when carrying out the method is provided.
  • the present invention relates to a method for casting a wholly (in full length) or partially (in longitudinal sections) insulated wall or other building component in preferably reinforced concrete by means of a disposable ' formwork comprising a plurality of interconnectable, substantially tubular formwork elements, each defining an internal partial cavity, said partial cavities in interconected formwork elements being in communication ⁇ with adjacent partial cavities through apertures provided in the formwork elements, enabling concrete flow between the formwork elements, said apertures possibly being utilized for the passage of reinforcing rods.
  • Interconnectable disposable formwork elements of the kind concerned are primarily known from Norwegian patent specification No. 165,605. However, these are not formed with a view of enabling casting of a wall or the like which is insulated over the entire length or in longitudinal sections, respectively. Insulating such a wall, requires the erection of an internal framework (half-timbering) which is filled with insulation and thereafter faced/boarded. This involves time-consuming and laborous additional operations.
  • the positional fixing is substantially simplified in connection with e.g. walls to be insulated over longitudinal sections only, as compared with a formwork having smooth internal side walls, wherein insulation bodies which only are to extend over sections of a casted, insulated wall's length, would have to be secured within the formwork in a completely different way (possibly nailed down) .
  • reinforcing rods are suitably used as spacer means for insulation, said reinforcing rods having a length corresponding to the extent of several interconnected disposable formwork elements in the longitudinal direction of the wall formwork.
  • a spacer means such as an iron rod, may be placed next to such a reinforcing rod, resting against the latter, said iron rod not having to contribute to the reinforcing function, for defining an insulation-accommodating chamber within a partial cavity.
  • any suitable and appropriate kind of insulation may be used, even if, for the time being, rigid, preformed insulation bodies or elements are preferred, preferably comple entarily shaped to the internal wall surface portions of the formwork elements, against which each single insulation body comes to rest, more or less loosely. If a force fit can be achieved between formwork element and insulation body, such a shape- determined positional fixing alone may be sufficient in order to keep the insulation body properly in place. Such a shape-determined positional fixing may be complemented or entirely substituted, respectively, by a power-determined connection, wherein e.g. spacing means, such as reinforcing rods, exert a positionally fixing pressure against an insulation body.
  • rigid insulation bodies may advantageously be used, said bodies according to the invention being provided with projections from at least one side face, so that said reinforcing rod is prevented from resting directly on the adjacent side face of the insulation body.
  • Said projections which may have the form of small knobs, beads or the like, are thus acting as spacing means between insulation body and reinforcing rod(s).
  • the insulation is inserted into the longitudinal mid-layer of the formwork, defined between two horizontally extending reinforcing rods or the like.
  • the insulation may be placed along one of the side faces of the formwork, or along both side faces. In principle, there is nothing to prevent placing one insulation body in the middle and another insulation body at one or both side walls of the formwork.
  • one may cast insulated, load-bearing wall structure.:; and insulated, non-load-bearing wall structures.
  • insulation will be inserted into the disposable formwork centrally or at one or both sides, while in resulting non-load-bearing walls substantially more insulation may be inserted into the formwork, e.g. both centrally within the formwork and outwardly toward the side walls thereof.
  • one may connect to one or more narrower formwork elements which thereby extend over a longitudinal section of the resulting wall.
  • an insulatable disposable formwork which may be used in order to carry out the method, it is possible to fill some of said reinforced partial cavities completely or substantially completely with concrete which, upon hardening, form "columns" of a wall structure, while the remaining partial cavities are insulated and filled with concrete only outermost at the side walls of the formwork.
  • Figure 1 shows a perspective view of three disposable formwork elements coupled together in per se known manner in order to form a longitudinal section of a wall formwork;
  • Figure 2 shows a corresponding perspective view, wherein instead of one of the identical formwork elements of equal width is connected to a substantially narrower formwork element which, together with several connected equal formwork elements (not shown) are to extend over a longitudinal section of a wall formwork where double reinforcement or insulation is not needed;
  • Figure 3 shows a horizontal section of a longitudinal section of a wall formwork comprising totally six identical formwork elements, where the internal partial cavities of the formwork have varying degree of filling in respect of insulation and concrete, two partial cavities in the middle having less insulation filling and more concrete filling than the remaining partial cavities;
  • Figure 4 - 9 show three interconnected, mutually identical formwork elements seen in horizontal section/top plan view
  • Figure 4 showing a centrally inserted insulation, defined between two parallel reinforcing rods extending in the longitudinal direction of the formwork, the insulation being in the form of rigid insulation bodies, and where reinforcing rods/iron rods inserted inwardly of said parallel reinforcing rods, serve as spacers for the insulation bodies;
  • Figure 5 showing insulation bodies inserted within two opposing areas of two partial cavities, and wherein as in figure 4 two horizontally extending, parallel reinforcing rods have been disposed, said rods restricting the freedom of movement of the insulation bodies inwardly from the outer positions thereof.
  • the insulation bodies are formed with small projections at a face which will be directed inwardly, said projections functioning as spacers as well as securing that concrete gets the opportunity of flowing outwardly past the reinforcing rods, covering these completely;
  • Figure 6 showing an embodiment wherein the insulation only consists of insulation bodies inserted outermost at one side wall of the formwork
  • Figure 7 showing an embodiment where the insulation covers approximately one half of two adjacent partial cavities, i.e. that the insulation extends from an imaginary longitudinal mid-plane of the formwork to one side face thereof;
  • FIG. 8 showing an embodiment where the insulation covers more than half of two coherent partial cavities
  • Figure 9 showing a case where two partial cavities/formwork elements included in a wall formwork, not shown, do not contain insulation; they are wholly filled with concrete, apart from two horizontally extending, parallel reinforcing rods which, possibly, may be omitted.
  • FIG 1 three identical interconnectable disposable formwork elements la, lb and lc are coupled together by means of coupling means of the engaging type.
  • These coupling means may e.g. be formed such as shown and described in NO patent No. 165,605.
  • these coupling means will have the form of cooperating tongues and grooves exhibiting L- respectively U-shaped cross-section.
  • the coupling means consist of L-shaped tongues 2 and, at the other end, of U-shaped grooves 3.
  • Each formwork element la - lc and 4a defines an internal partial cavity la' - lc' and 4a 1 , respectively, which - when two or more formwork elements are interconnected - communicate with each other through apertures 5 formed in the walls of the formwork elements, thus constituting a portion of a coherent formwork cavity, such that concrete may flow between the partial cavities la 1 - lc' and 4a 1 .
  • peripheric insulation bodies 6 have been inserted. At one side thereof, these insulation bodies are shaped complementarily to the adjacent portion of the polygonal formwork elements la - If according to the embodiment.
  • the element If is shown in an empty condition, in order to illustrate the shape of the partial cavity If.
  • a horizontal reinforcing rod 7 serves, together with the shape-determined connection between insulation body 6 and formwork element, to fix the respective insulation body 6 positionally.
  • each insulation body 6 is formed with small projections 6' which, thus, serve as spacers.
  • rigid insulation bodies 6a are inserted, the latter being shaped complementarily to the cross-sectional portion of the partial cavity to be covered by each insulation body 6a (more than 50% in the embodiment shown) , said insulation bodies, moreover, being fixed positionally by means of a common horizontal reinforcing rod 7a.
  • the insulation bodies 6a have also small projections 6 ', which may have the same shape as the projections 6', and which act in the same manner as these.
  • Figure 4 shows an embodiment where central insulation bodies 6b having rectangular cross-sectional shape have been inserted into two of three coherent partial cavities of interconnected formwork elements la - lc.
  • These centrally placed insulation bodies 6b are, prior to the concrete casting process, positionally fixed by means of two parallel, horizontal reinforcing rods 7b and vertical reinforcing rods 8 or similar spacer rods which may, but do not have to, be incorporated into the regular reinforcement.
  • the vertical reinforcing rods 8 serve approximately the same purpose as the projections 6', 6a' of the insulation bodies, namely to ensure flow of concrete also at the inner side of the horizontal reincorcing rods 7b.
  • the interconnected formwork elements la - lc of figure 5 have octagular cross-sectional shape, and rigid insulation bodies 6 are allotted a circumferential shape which complementarily corresponds to the inner wall portion of respective formwork element la, lb against which they come to rest, whereby a certain shape-determined positional fixing of the insulation bodies 6 is achieved, said positional fixing being assisted by two horizontal, parallel reinforcing rods 7b, which causes a power- or force-determined positional fixing in respect of the insulation bodies 6.
  • the insulation bodies 6 have projections 6' acting as spacing means, ensuring flow of concrete also outside the reinforcing rods 7b. The mid-space between the insulation bodies is filled with concrete.
  • the embodiment according to figure 6 differs from that of figure 5 only in that insulation bodies 6 of figure 6 merely are placed at one side of the formwork.
  • a wall casted in accordance with the suggestion of figure 6 would, of course, have a larger load-bearing strength then walls casted in accordance with the suggestions of figure 4 and 5, because the concrete cross-section is the largest in figure 6.
  • longitudinal reinforcing rod 7b serves as positional fixing means for the insulation bodies 6, while a reinforcing rod 7c, parallel with the reinforcing rod 7b, exclusively is included in the wall reinforcement.
  • figure 7 differs from that of figure 6 merely in that concrete and insulation in figure 7 each covers approximately one half of the cross-section of the partial cavities la' and lb'.
  • a central, horizontally extending reinforcing rod 7b forms a positional fixing means for insulation bodies 6c, while a reinforcing rod 7c, parallel to the reinforcing rod 7b, merely is included in the wall reinforcement.
  • 6' denotes projections on the side face of the insulation bodies 6c which is directed towards the positional fixing reinforcing rod 7b.
  • insulation bodies 6a are inserted prior to the concrete casting process, said insulation bodies covering the central and one outer portion of the partial cavities, only the other outer portion being capable of receiving concrete.
  • Positional fixing of the insulation bodies and spacing in respect of the reinforcing rod 7b are effected in the same way as in figures 5 through 7.
  • Figure 9 shows a longitudinal portion of a wall formwork, where interconnected formwork elements la and lb do not contain insulation.
  • the completely concrete- filled formwork elements la, lb - possibly more than two interconnected elements - form a load-bearing "column", while other formwork elements, not shown, of the same wall formwork will be provided with insulation of desired shape and desired positioning and positional fixing within the individual partial cavities la' - If.

Abstract

Procédé rationnel de coulage d'un mur ou d'autres éléments totalement ou partiellement isolés en béton de préférence armé d'un édifice. On utilise à cet effet des coffrages perdus faits de plusieurs éléments de coffrage sensiblement tubulaires interconnectables (1a-1f) dont chacun délimite une cavité intérieure partielle (par exemple 1f'). Quand les éléments du coffrage sont interconnectés, ladite cavité communique avec des cavités adjacentes par des ouvertures ménagées dans lesdits éléments (1a-1f). Ces ouvertures permettent au béton de s'écouler entre les éléments et peuvent servir à passer des barres (7, 7a) d'armature. Pour les murs isolés, on insère au moins dans certaines des cavités (par exemple 1f') constituées par les éléments interconnectés (1a-1f) du coffrage, une isolation (6, 6a) dont la mise en place répond à des considérations de conception et/ou de force complémentaires à l'aide d'entretoises se présentant, par exemple, sous la forme de barres (7, 7a) d'armature placées au moins du côté libre de ladite isolation (6, 6a)).
