Definitions

  • the present invention relates to a method for enlarging the living area in a dwelling house, preferably a relatively small or medium-sized single-family house/terrace house with ridge, saddle or hipped roof, where the roof trusses have a top angle which is so large that the loft cannot be lived in and which in all other respects correspond with the introductory part of the subsequent claim 1.
  • the invention also relates to a new roof construction with new technical detail solutions for use when implementing this method.
  • the disadvantage of an extension is primarily that the costs are relatively high, mainly due to the fact that the same work has to be carried out as when erecting a one-family house, i.e. foundation work, foundation walls, main storey and roof.
  • the costs of an extension can be compared with the costs of a single-family house . , leaving aside in either case the possibility of work by the owner himself. (The price per square metre of living area today amounts to about kr.
  • a definite advantage of opting for enlargement of the living area by extension as compared with the above mentioned building-on of a loft storey suitable for living in consists in the fact that the owner can continue to live in the house and to use it while it is being converted.
  • a similarly definite disadvantage consists in the encroachment on the site and the reduction of the site area. Furthermore enlargement of the area by extension can frequently be impossible owing to the fact that the sites in regulated building estates are frequently not sufficiently large to allow enlargement of the house by extension, and in such cases the enlargement of the living area has been inhibited.
  • the general aim has been to avoid, the disadvantages and defects associated with the state of the art and thus to arrive primarily at a method involving such measures as to enable the work to be carried out very quickly and particularly efficiently, another aim being to achieve a construction of high mechanical strength and low weight. Further, closely related objects will be apparent from the following description.
  • the costs are inter alia roughly half as high as the costs per square metre of living area (the calculated average price amounts to about kr. 2,500 incl. VAT per square metre of living area as in January 1986).
  • the construction time is short since the specialised work can normally be completed within 10 hours, the entire duration of the work having been calculated as amounting to from 10 to 12 days.
  • the method in accordance with the invention also involves a minimum encroachment on the living floor of the house,- it being sufficie to change and mount the staircase; there is no reduction or disturbance of the used site/ground area and no conflict as regards the boundaries of adjacent property.
  • the "construction pack" on which the method ' and the prefabricated roof elements for its implementation are based comprises the following steps:
  • New drawings are prepared (facades, sections and plans).
  • the probl of a staircase leading to the loft is solved by locating it above the existing basement staircase, or in the case o houses without basement, by using one of the floorson the main level as an area for the staircase.
  • the council has granted building permission, the building work can commence.
  • 3- Removal of existing roof floor and the gable top cladding (which can be carried out by the owner himself) . It should be noted that upright boards, roof gutters, rainwater heads and suspended roofs/ underroofs or possible shingles are normally not to be dismantled.
  • the new system is in principle based on this being retained and the roof being tight during the construction period, which again means a reduction in costs. 4- Once the dismantling operation has been completed, 3 joiners are put to work on the building and the new construction 2 is mounted.
  • the roof construction is prefabricated and dimensioned according to the calculations in such a way that laths for ventilation and cladding are not necessary (see design of rafters).
  • the new roof construction 11 is placed next to the old construction 10 and glued and nailed to the latter.
  • additional support is achieved, and the ceiling in the main storey is not affected by the construction work.
  • the subchord/beam of the new trusses is so dimensioned that with regard to the clear span between the jamb walls the layer of beams becomes self-bearing, i.e. that a support is not necessary. With extra long spans subchords/loft beams can be clamped and for further reinforcement hidden supports resting on the outer walls can be provided.
  • the suspended roof and laths are assembled (one gable is open) . According to the calculations it takes three men about 10 hours to assemble the trusses and to seal the new outer roof and gables.
  • the old roof and the trusses 1 which are within the living space of the new loft floor are removed and taken out through the open gable. Subsequently windows are fitted, the roof is covered e.g. with concrete tiles, the gable walls are fitted with laths and clad, the staircase is changed and the staircase leading to the loft is fitted.
  • hipped roofs too can be converted according to the same system, with that difference that on the gable sides the roof is closed with a half hip up to the loft gable.
  • the gable wall is pulled back 120 cm by comparison with the gable wall of the dwelling house.

Abstract

La configuration de charpente/configuration de grenier est une configuration de charpente préfabriquée, non-assemblée qui est assemblée sur le site de construction. On utilise une partie de l'ancienne configuration qui sert de support auxiliaire. En passant la partie inférieure de la semelle de poutre à travers le toit existant et en construisant le nouveau toit au-dessus, on obtient un toit étanche pendant toute la durée de la construction. Cette configuration permet de réaliser des planchers et des greniers suspendus librement et pouvant être situés comme on le désire. Le procédé est caractérisé en ce que l'on découpe un évidement dans les côtés de l'ancienne charpente de combles des deux côtés du toit, après quoi on passe les parties inférieures de semelles de poutres (poutres) que l'on assemble avec les parties inférieures de semlles de poutres existantes. Le piètement est spécialement adapté de sorte que lorsque les poutres traversières sont montées, on utilise les anciens chéneaux de tête et de toit. Lorsque le nouveau toit est étanche, l'ancien toit est enlevé jusqu'au niveau des murs de soutien. Sur de longues portées, des poutres en fer peuvent être passées à travers les parties inférieures de semelles de poutres.
