METHOD, ARRANGEMENT, LID AND ADAPTER FOR DRYING A WATER DAMAGED FLOOR

Abstract

A water damaged floor (10) is dried by forming an opening (18) in a flooring (14) of the floor and creating and forcing an airflow from a surrounding space (28) through the opening (18) into a ventilating space between the flooring (14) and a sub-floor (22). According to the invention, an end portion of the flooring (14) is elevated from the subfloor (22) for creating said ventilating space and for creating an air passage (27) between the ventilating space and the surrounding space (28) at an edge of the flooring (14).

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

[0033] In FIG. 1, a floor 10, including a floating flooring 14, such as comprising a parquet surface layer 16 and having a water damage 12, is being dried by using an arrangement of the invention. In this context, floor having a water damage is to be broadly understood as the portions of the flooring, subfloor and adjoining structures that are susceptible for being dried by the method and arrangement according to the invention.

[0034] In the embodiment shown, the arrangement comprises an air conditioning device 30, a manifold 34 and an adapter 40 connected by tubing 32, 38.

[0035] The air conditioning device 30 is adapted for providing a conditioned airflow capable of drying the floor 10 in a manner to be later described. Device 30 comprises a blower or fan 30A and typically also one or more components 30B for further necessary air treatment such as heating and dehumidifying/drying the airflow to be forced through the arrangement via tubing 32, 38. In certain circumstances it may, however, be sufficient to use an unconditioned airflow. While the fan 30A typically will force the airflow by overpressure, it could conceivably also force the airflow by suction.

[0036] As diagrammatically shown in phantom in FIG. 1, the manifold 34 may be used in cases when there is a need to distribute the conditioned airflow to a plurality of adapters 40 through outlets 36, depending on the extent of the water damage.

[0037] The adapter 40 is shown in in greater detail in FIGS. 2-4. With reference to FIG. 4, adapter 40 includes a base or base plate 42 having means including a pipe stud 44 with a throughbore 45 to be connected to an end of tubing 38 for guiding the airflow through the base plate 42. Pipe stud 44 needs not to extend perpendicularly from base plate 42, but can be oriented at any angle convenient for connection to the end of tubing 38 as illustrated in phantom in FIG. 3.

[0038] Base plate 42 is adapted to be sealingly attached to the flooring 14 around an opening 18 formed in the flooring 14 at and end portion 11 (FIG. 1) of the floor 10. In a typical case when the flooring 14 comprises a parquet surface layer 16, the opening 18 may be machined in the flooring 14 prior to the drying operation, for example by a router (not shown), to a generally rectangular shape as shown in FIG. 4.

[0039] In the embodiment of FIG. 4, the means for attaching the adapter to the flooring 14 comprise screws 56 to fasten the base plate through screw holes 46. However, other means for attachment are conceivable to the skilled person, such as releasable screw clamping means extending through the opening and engaging a bottom face of the flooring 14 (not shown).

[0040] The arrangement according to the invention further has an elevating device for elevating the above-mentioned end portion 11 of the flooring from a subfloor 22. In this context, end portion may be any lateral, longitudinal or other end portion of the flooring. In the embodiment of FIG. 4, the elevating device is incorporated in the adapter 40 and comprises a pair of pushing elements. Each pushing element includes a screw 50 having an external thread engaging an internal thread of a respective bore 48 in the base plate 42. Each screw 50 has a bottom pad 54 for engaging a subfloor 22, and a top handle 52 to be manually turned for pushing the adapter 40 and attached flooring 14 away from the subfloor 22, thereby creating a ventilating space 26 (FIG. 3) between flooring 14 and subfloor 22.

[0041] As diagrammatically indicated in FIG. 1, in order to be capable of manually operate the elevating device at a distance from the opening 18, the two handles 52 can be replaced (or supplemented) by a preferably telescopically extendable single rod 70 having a handle (not shown), a distal universal joint 72 and a socket 74 that is releasably connectable to either screw (or handle). Then, an operator does not need to stand in the vicinity of the opening 18 and unnecessarily load the flooring 14 with the weight of the operator when operating the elevating device. The operation is thereby also facilitated for the operator.

[0042] In the embodiment shown, flooring 14, in addition to the relatively stiff surface layer 16, also has a relatively flexible subsurface layer 20. Such subsurface layer 20, that is often made of a synthetic foam, usually has the function of a resilient support for the surface layer 16. In order to allow a forced drying airflow also between the surface layer 16 and subsurface layer 20, top face of subsurface layer 20 can be intermittently attached, such as by gluing, to bottom face of surface layer 16 at patches 60 in the vicinity of the opening 18, as shown in FIGS. 4 and 5. As illustrated by arrows in FIG. 5, the forced airflow to the ventilating space 26 will then be able to enter also an additional ventilating space 19 between layers 16, 20 via gaps between adjacent patches 60.

[0043] To restore the flooring 14 when the drying operation is completed, the opening 60 can be closed in a manner known per se by a correspondingly shaped lid of flooring material. In case adapter base plate 42 was screwed to flooring 14, opening 18 may need to be enlarged to remove screw holes 58 (FIG. 6) left in the flooring 14. As diagrammatically shown in FIG. 6, an accordingly enlarged opening 18B can be formed in surface layer 16, having a perimeter shaped with great precision by using a template (not shown) capable of guiding a routing tool 60 around the enlarged opening 18B to be formed thereby. A lid 62 shaped in correspondence with the enlarged opening 18B can be used to close the enlarged opening and seal it by gluing.

[0044] The closing of the opening 18 may also be made by other methods, known per se. With reference to FIG. 7, one such other method to obtain a high-finish closure, may be to position a bottom support pad or block 64, roughly corresponding to the outline of the opening 18, in the opening 18, and then remove only a top layer of a larger area 18C, e.g. by routing, around the opening at a thickness of a thin finishing piece, element or veneer 66 to be carefully inserted and glued into the larger area 18C, supported by the pad or block 64. When convenient, of course also a full new flooring element could replace a full flooring element containing the opening (not shown).

[0045] The foregoing detailed description is given primarily for clearness of understanding and no unnecessary limitations are to be understood therefrom. Modifications will become obvious to those skilled in the art upon reading this disclosure and may be made without departing from the spirit of the invention or the scope of the appended claims.
