Abstract

A building plate and a door frame made from such a building plate, where the building plate consists of two or more particle boards (1, 2) with a fibre board (3) arranged and glued in the space between the particle boards in order to obtain increased form stability and improved screw holding strength. In making the door frame an abutment list (6) of solid wood is arranged on one side (1) of the building plate, the building plate preferably having a veneer covering (4) of the same kind of wood, the edges of the door frame also being provided with the same veneer covering or an edge list (5).

Description

Arrangement relating to a door frame.
The present invention relates to an arrangement relating to a building plate of sandwich construction, and a door case or frame made from such a building plate.
Within the construction industry it is known to use particle boards to a large extent as facing for floors, ceilings and walls, but also for furnishings such as closets, furniture etc. It is also known that particle board provides relatively poor attachment for screws subjected to tensile loads. Usually one attempts to solve this problem by special particle board screws or expansion sleeves in which the screws are arranged. Even with such expansion sleeves it happens that when the screw and sleeve are subjected to high loads, the attachment in the particle board fails, so that the screw and sleeve are pulled out of the particle board. It has therefore for a long time existed a desire for improving the known particle boards in an inexpensive manner in order to improve their screw holding strength, whether the attachment takes place by screwing directly into the board or by means of said expansion sleeves.
According to the invention it is therefore suggested that the arrangement consists of two or more particle boards between which a fibre board, preferably of the hard type, is arranged and glued.
In such an arrangement it is possible to substantially improve the holding strength of screws in the building plate and therefore increase the extraction resistance of the screw or screw with expansion sleeve.
The present device or arrangement can be produced from particle board and fibre board which are common articles of commerce, and according to the invention the external surface of the particle boards of the new building plate are advantageously provided with a surface coating or covering, e.g. veneer. Such particle boards are also common articles of commerce .
In the manufacture of door frames it has been common to use solid wood, the frames of this kind giving good screw holding 5 strength. However, such, door frames often become relatively costly, particularly if the door and door frame are to be made from expensive kinds of wood. For some kinds of wood the form stability is relatively poor when subjected to changes in temperature and humidity, a risk existing for the
•JO door blade to become jammed in the door frame due to form changes in the latter. Laminated structures, as known from the traditional furniture plates, will not be particularly suited for door frames, particularly due to their complicated and expensive structure. Nor is plywood suitable for use in
15 door frames due to the relatively high production cost and since processed plywood may have an unattractive appearance. Furthermore, it is a fact that plywood is not always easy to process due to its tendency for chipping. Nor are the common particle boards suitable for door frames due to the
20 material being too brittle for use in door frames, where the loads may be high. Furthermore, a particle board provides poor screw holding strength for hinges.
It is therefore suggested according to the invention that the 25 door frame be made from a building plate as defined above, where the width of the door frame is cut from a building plate made as indicated, and where, on the side of the door frame which will face the door blade, an abutment list of solid wood is arranged, the abutment list preferably being of 30 the same kind of wood as the veneer coating on the building plate. As soon as this is done, the edges of the door frame may be provided with lists of the same type of wood as the veneer coating and the abutment list. This covering list may be glued or nailed or screwed to the door frame, the latter 35 solution most likely being preferable in order for the door frame to have an integrated appearance and giving the impression of being a door frame made of solid wood. In this way a door frame is obtained which has form stability, provide good screw holding strength for door hinges and permits the use of finer woods which otherwise would not be suitable for the solid wood application in a door frame due to the factors mentioned above and the cost of the wood materials.
The invention will be described more closely with reference to the appended drawing.
Figure 1 illustrates a building plate according to the invention.
Figure 2 illustrates a door frame made from a building plate according to the invention.
Figure 3 shows a modification of a door frame according to Figure 2.
In Figure 1 it is shown a building plate consisting of two particle boards 1, 2 with a fibre board 3 arranged in the space between the particle boards and glued to these, the fibre board preferably being of the hard type. On their external side the particle boards may be provided with a surface covering, preferably veneer 4. As is apparent from Figure 2 , from the building plate in Figure 1 a piece is cut corresponding to the depth of the door frame and also its height and width. The longitudinal edges of the door frame are covered with a list 5 of the same kind of wood as the veneer covering 4. Furthermore, a groove is milled out of the particle board part 1 wherein an abutment list 6 for the door blade is attached. This abutment list should be made of solid wood and of the same kind of wood as the veneer covering 4 or the list 5. Thus, the door frame will receive an integrated appearance. There is of course no reason why said veneer coverings 4 , 5 cannot be omitted in particular cases, e.g. where the door frame is to be painted.
In Figure 3 a modification is hown of the door frame accordin to Figure 2, wherein, instead of surface treatment with veneer or painting, a plastic casing 7 is used formed so that it may be snap fitted in place in a groove 8. It will be understood that the invention is not restricted to the use of only two particle boards and one fibre board therebetween, as indicated in Figure 1, but that several particle boards and a corresponding number of fibre boards may be used in making the building plate according to the invention.

Claims

C l a i m s
1. An arrangement relating to a door frame made at least partly from a material comprising glued elements of particle
