Description

Expansion clamp and application for assembling windows..
The invention relates to an expansion clamp for assembling building elements such as windows and doors in buildings such as houses.
The invention also relates to application of expansion clamp.
It is known to assemble windows and doors in buildings where the most known technique for this includes application of screws, which are screwed through the frame, from e.g. the window frame's internal side, and into the end surface of typically the brickwork or woodwork, which constitutes the material in the building opening where the window is to be mounted.
It has been found, however, that this known technique involves some drawbacks, including that the technique leaves the window frame with visible screw heads from the screws, which are screwed through the frame for fastening the window, which is to be mounted.
Moreover, the material around the visible screw head can be damaged after the screw assembly.
The known technique thus entails that the mounted building elements including doors and windows must be repaired, after mounting and installation, including covering the visible screw heads and painting once more, which is time demanding and personnel demanding and thereby costly for the total building activity.
From EP 0147563 A2 is known an expansion clamp for fastening a doorframe or window frame to an opening in e.g. brickwork.
The expansion clamp consists of a plate with a shape, which mostly corresponds to, and looks like a U, where the two pins or straight shapes consist of respectively another side plate (81 ,82), which is connected by an end plate (83) with a hole. The first and the second side plate (81,82), which can be provided with teeth, partly extends from an area from the end plate (83) in a direction away from this and partly in a direction away from each other. The expansion clamp also includes a screw, which via the hole and a nut (92) is in contact with the end plate (83). The screw is rotatabiy connected with a gliding element (10), which is positioned towards the two side plates (81,82), and which is movable in a direction perpendicular to the end plate (83).
It has been found, however, that the expansion clamp, according to EP 01 7563 A2, is not sufficiently resistant to the power effects, which building elements, to which it is intended for application and use, in practice are exposed to.
It is therefore an object of the invention to improve the known technique including expansion clamp, method and application. The object of the invention is achieved by an expansion clamp of the type stated in claim 1 , which is characterized in that the expansion clamp consists of a plate with a shape, which mostly corresponds to a U where the two pins or straight shapes consist of respectively a f irst and a second side plate (7,8), which are connected by an end plate (11) with a tap hole. The first and second side plate partly extends from the end plate in a direction away from it and partly in a direction towards each other. The first side plate, which is longer than the other side plate, in its free end includes a 180 degree inwards folding, while the other side plate's free end ends in an outward folding with a number of outward facing teeth such that these can be connected with e.g. a frame. The expansion clamp also includes a screw, which via the tap hole is in connection with the end plate. The screw's end opposite the screw head is rotatably connected with a gliding element, which consists of a wedge or cylinder, which abuts on the two side plates and which are movable in a direction perpendicular to the end plate. In this way it thus becomes possible to manufacture and produce an expansion clamp for mounting building elements such as windows or doors without any screws being needed for the mounting for penetrating the window frame or doorframe. Thus, there is no visible mounting parts after the mounting of e.g. the window and therefore, no later repairs are required.
The total mounting process thereby becomes less time consuming and less personnel requiring and thereby less costly to complete.
With the new technique it is achieved that the expansion clamp can resist the forces, which the mounted building elements are exposed to.
The invention differs from the technique known from EP 0147563 A2 since: the expansion clamp consists of a first and second side plate, which cover an area from the end plate in a direction away from it and partly in a direction towards each other. the end plate includes a tap hole.
The gliding element is shaped as either a wedge or a cylinder.
The first side plate is longer than the other side plate.
The first side plate's free end ends in a 180 degree shaped fold or folding and the second and other side plate's free end ends in an outward folding with a number of teeth such that these can be connected with e.g. a frame. As mentioned, the invention also relates to the application of expansion clamps for mounting of building elements such as windows and doors in buildings such as houses.
The invention will now be explained more fully with reference to the drawings, in which:
Fig. 1 shows a ixture for fastening an expansion clamp.
Fig. 2 shows, in a frontal slanting projection, an expansion clamp.
Fig. 3 shows, seen from the side, an expansion clamp.
Fig. 4 shows, seen from the side, a fixture with a partially inserted expansion clamp.
Fig. 5 shows, seen from the side, a fixture with an inserted expansion clamp.
Fig. 6 shows, seen from above, a fixture with an inserted expansion clamp.
Fig. 7 shows, seen from above, a fixture with an inserted expansion clamp placed between a building opening area to which the fixture is fastened and an area of a building element such as a window frame, which is to be mounted in the building opening area.
In fig. 1 is with 1 shown a fixture, which is mounted on a building opening end area or surface 5 to which a building element 14 is to be mounted such as a window or a door.
The fixture 1 can be produced and manufactured by bending a rectangular preferably metallic plate such that the fixture has two abutting surfaces 4, typically with each own hole for insertion of mounting screws and a middle piece, which is raised 2 in relation to the abutting surfaces 4 such that the elevation 2 creates a passing opening in the fixture 1 when it is mounted to a building opening end area 5.
Fig. 2 shows an expansion clamp 6, which is characterized in that the expansion clamp 6 consists of an end plate 11 , which preferably in the middle is penetrated by a screw element such as an Allen screw 12, which is screwed into a gliding element 9, which on one side is enclosed by a side plate 7, which comes out from the end plate 11 and ends in a barb edge 13 and on an opposite side it is enclosed by a side plate 8, which also comes out from the end plate 11 and which in the opposite end is provided with teeth 10, whose ends turn away from the gliding element 9. The barb edge 13 is typically manufactured by folding the plate, which consists the side plate 7.
It is furthermore a characteristic of the expansion clamp 6 that the side plate 7, which ends with a barb edge 13, is longer than the opposite side 8, which ends with a row of teeth 10.
By appropriate dimensioning of respectively the fixture 1 and the expansion clamp's 1 barb edge 13, the expansion clamp 6 can by manual push down of the barb edge 13 be taken out once more from the fixture 1.
In fig. 3 is shown an expansion clamp 6, seen from the side, whereby it is made visible that the gliding element 9 by appropriate fastening of a screw element such as an Allen screw 12, which penetrates the side plate 11 via a tap hole, by activation of the screw element; can glide forwards or backwards between the plates 7 and 8.
When the gliding element 9 via turning of the Allen screw 12 is moved away from the end plate 11 , it will force the side plates 7 and 8 away from each other whereby the distance between the side plates 7 and 8 are increased, which corresponds to the expansion of the expansion clamp 6.
By expansion of the expansion clamp 6, the teeth 10 will thus be forced away from the opposite side plate 7.
In a preferred embodiment, the gliding element 9 is manufactured cylindrical, which test has shown provides the most efficient expansion effect in the expansion clamp.
In fig. 4 is shown, seen from the side, how an expansion clamp can be inserted in a fixture 1, which is mounted on a building opening end area 5.
The barb edge 13 is thus led through the opening 2 in the fixture with the teeth 0 turned away from the fixture 1.
Fig. 5 shows, seen rom the side, an inserted expansion clamp 6 in a fixture 1.
Fig. 6 shows the same configuration as fig. 5, but seen from the side.
In fig. 7 is shown how an expansion clamp 6 is placed in a fixture 1, which is inserted in a fixture 1 , which is mounted on a building opening end area 5 and where the teeth 10 of the expansion clamp 6 point towards an area or surface of a building element 14 such as a window, which is to be mounted to the building opening area 5.
When the screw element, as here an Allen screw 12, is activated by being turned in the correct direction, the gliding element 9 will force teeth 10 away from the building opening end area 5, and then later penetrate the close side of the building element 14 whereby the building element 14 in the penetration area is fastened to the building opening area 5. By repetition of the above method and technique, a number of fixtures 1 and expansion clamps 6 can fasten a building element 14 such as a window or a door with the same strength and force as traditional technique, which applies visible screws through the frames of the building elements 14.
