Definitions
- the invention relates to a prefab building part, comprising a load-bearing construction part with a bottom side, a top side and at least one side wall, as well as a cladding mounted against the side wall of the load-bearing construction part.
- a load-bearing construction part is meant a structurally supporting frame that offers strength to the whole of which it forms part and to which other, non-load-bearing parts, such as the cladding and insulation material, can be attached.
- the stiffness and strength of the prefab construction part is therefore mainly or almost entirely determined by the stiffness and strength of the load-bearing construction part.
- Such a prefab building part is known from NL 8702873 A in the design of a prefab chimney.
- the load-bearing construction part is formed by a metal tube in which channels (pipes) are present and against which outer wall plates are attached, that are covered with, for example, brick slips.
- the metal tube is composed of two parts that are attached to each other via bolts. This makes it possible to compensate for any dimensional deviations by connecting the parts at a short distance from each other.
- the disadvantage of this is that the duct is not completely watertight and water can leak in, which can then seep in through holes in the roof on which the chimney is fitted.
- GB2551611A discloses a prefab building part, inter alia in the form of a chimney, in which the supporting structure is composed of several supporting structural parts (preferably of wood). This supporting construction is covered with a plastic cover plate. Furthermore, this known prefab building part is provided with insulation material.
- An object of the invention is to provide a prefab building part of the type described in the preamble in which the load-bearing construction part is completely watertight and in which there is no risk of water leaking through.
- the building part according to the invention is characterized in that the load-bearing construction part is made of plastic and is integral. Due to a load-bearing construction part of one whole, there are no interconnected parts where the connection could leak.
- the load-bearing construction part is preferably manufactured from a solid block of plastic, preferably EPS.
- the prefab building part is preferably provided with a foot that is attached to the underside of the load-bearing construction part for mounting the building part on a subsurface, for instance a (pitched) roof of a house.
- the load-bearing construction part of the building part which is made from a plastic block, offers insufficient grip for a screw screwed into it to firmly fix a part (for example the foot) to the load-bearing construction part.
- an embodiment of the prefab building part according to the invention is characterized in that at least one hole is present in the plastic block in which an auxiliary element (for example a wooden slat) is located, into which at least one screw having a threaded end is screwed so that a part is securely attached to the load-bearing construction part.
- the screw preferably protrudes through the foot of the chimney and is screwed with the threaded end into the auxiliary element, so that the foot is firmly attached to the load-bearing structural member.
- the screw can also be provided with a lifting eye and protrude through the top of the load-bearing construction part and again be screwed with the screw-threaded end into the at least one auxiliary element, so that a lifting eye can be firmly attached to the load-bearing construction part.
- the prefab building part is designed as a prefab chimney for placement on a sloping roof of a house, wherein the shape of the load-bearing construction part is equal to the shape of a chimney with a chamfered underside at one or more angles equal to the angle of inclination or angles of inclination of the roof.
- the shape of the load-bearing construction part is equal to the shape of a chimney with a chamfered underside at one or more angles equal to the angle of inclination or angles of inclination of the roof.
- one or more vertical channels can be arranged in the load-bearing construction part and through the foot to allow passage of one or more chimney pipes and/or ventilation pipes.
- the invention also relates to a method for manufacturing a prefab building part.
- the invention is characterized in that the load-bearing construction part of the building part is manufactured from a solid plastic block by cutting away parts of the plastic block with a hot wire cutting machine.
- a load-bearing construction part consisting of one whole is obtained with no seams through which water could seep. Because it consists of a whole, no fastening materials or fastening techniques need to be used to connect parts to each other.
- An embodiment of the method is characterized in that a through hole is cut in the plastic block by moving the heated wire, while cutting from one side of the plastic block, in a meandering manner to the place where the through hole is to be formed and there cutting out the through hole and then moving the heated wire back through the same meandering cut.
- a hot wire cutting machine the ends of the cutting wire are held in the machine. It is not desirable to first drill a hole in the plastic block and then run a wire through it and fix it with the ends in the machine. This is way too time consuming. Therefore, the cutting wire cuts into the block from one side of the plastic block to the point where a hole is to be made.
- a meander-shaped cut which is preferably such that the parts on either side of the cut interlock and hold each other so that they cannot be moved apart.
- FIG. 1 shows an embodiment of the building part according to the invention.
- the building part is designed as a chimney 1.
- the chimney is arranged on the ridge of a roof.
- the chimney 1 is constructed from a load-bearing construction part 3, the side wall 3c of which is clad with brick slips 5.
- the space between the brick slips is filled so that the appearance of the prefab chimney does not differ from that of a conventional chimney.
- the top side 3b of the load-bearing construction part 3 can be covered with a cover plate, for instance a concrete plate.
- the bottom side 3a of the load-bearing construction part is chamfered so that the shape fits on the ridge of the roof 25.
- a foot 7 is fixed against the bottom side 3a of the load-bearing construction part, with which the chimney is fixed to the roof 25.
- the foot 7 in this embodiment is formed by wooden plates and protrudes outside the chimney.
- the base is fixed to the roof 25 with bolts 21.
- FIG 2 in which the chimney present on the roof is shown in top view.
- the load-bearing construction part 3 is manufactured from a solid plastic block.
- a channel 17 is arranged in this plastic block, through which a chimney pipe 18 is inserted.
- Figure 3 shows the load-bearing construction part 3 with the foot 7 of the chimney attached thereto.
- the load-bearing construction part 3 forms a whole and, except for the holes made in it, is completely solid.
- the load-bearing construction part 3 is made of EPS and is provided with ribs 23 between which the brick slips can be glued.
- auxiliary elements 11 are inserted into these holes 9. These auxiliary elements are there to provide support for screws 13 and 15 with which parts are fixed to the load-bearing construction part.
- the auxiliary elements 11 are formed by wooden slats/blocks.
- the screws 13 protruding through the foot 7 are screwed with the threaded ends 13a into these wooden slats/blocks so that the foot 7 is firmly attached to the bearing construction part 3.
- the screws 15 on the top side 3b of the load-bearing construction part are also screwed into the wooden slats/blocks with a threaded end 15a and are provided with a lifting eye 15b at the other end.
- FIG 4 the top right comer of the load-bearing construction part shown in figure 3 is enlarged.
- a through hole 9 has been made in the load-bearing construction part 3, into which an auxiliary element 11 has been inserted.
- a meander-shaped saw cut 19 is made in the block from one side, for example the top side 3b, up to the contours of the hole 9 to be formed and then the hole 9 is cut into the block.
- the hot wire is then displaced again via the meandering cut 19 from the supporting construction part 3.
- the prefab building component can also be a building component other than a chimney, for example a pillar next to the driveway in which a letterbox may or may not be integrated.
- the foot can then be designed as a concrete slab.
