Abstract

A connection between floor or ceiling and wall in a building, wherein the wall (1) comprises a support structure (3) and the floor comprises elongated floor elements (9) which with a dovetail-shaped end portion (10) rest on a support beam (3) via respective contact surfaces (11, 12). The contact surfaces (11, 12) are inclined surfaces which secure the floor element (9) to the wall (1). The support beam is part of a wall element (1) consisting mainly of rigid foam material (6).

Description

FLOOR TO WALL CONNECTION
The present invention relates to a connection between floor or ceiling and wall in a building.
When using prefabricated elements in a building, good solutions for joints and junctions between the elements are essential. Especially the transition between floor and wall is challenging because horizontal forces arise against the wall. Wind pressure gives horizontal load inward, and wind suction gives horizontal load outward. It is known to use steel angles at the top and bottom in this connection, but this is expensive and unaesthetic, especially for homes The invention aims to remedy this situation and is more closely defined in the claims. The invention is particularly advantageous in connection with such wall elements which are disclosed in the applicant's co-pending application on a prefabricated, insulated outer wall.
Thus, the invention is based on a floor-to-wall connection, the wall comprising a support structure and the floor comprising elongated floor elements resting with the end portion on the support structure via respective contact surfaces. The contact surfaces are inclined surfaces whose inclination seeks to retain the floor element in the support structure.
For a better understanding of the invention, it will be described in connection with the exemplary embodiments shown in the accompanying schematic drawings, in which
Figure 1 is a vertical section through an outer wall supporting floor elements, and
Figure 2 is a section in isometric perspective of a floor composed of a modification of the floor elements.
Figure 1 shows a wall 1 comprising floor high wall elements 2 stacked on one another in a multi-story building. The wall element 2 has an upper supporting beam 3 and a lower supporting beam 4. The beams 3, 4 are connected to each other by means of supporting columns 5, shown here as a hidden contour. Beams and columns are partially enclosed and connected to a rigid, thermally insulating foam material 6, preferably polyisocyanurate or phenyl foam. The wall elements 2 are provided on the outside with a weather skin or cladding 7 of plaster or concrete, and the wall is provided on the inside with an acoustic liner 8 which can provide room for wires and pipes. Beams and columns are shown here in reinforced concrete and can be cast in grooves cut into the foam material. If desired, the concrete can be completely or partially replaced by other building materials, such as laminated wood, solid wood and metal sections. Figure 1 shows two floors represented by floor elements 9. These have an end portion 10 which is formed at the bottom with an inclined surface 11, which corresponds to an inclined surface 12 on top of a supporting beam 3 in a wall element 2, so that the weight of the floor element will attempt to pull it in the direction of the wall element until an edge 13 at the inner end of the inclined surface 11 stops such movement. The effect of the sloping surfaces 11, 12 and friction between them will prevent the wall from moving outward by wind suction, and the edge 13 will prevent the wall from moving inward at wind pressure.
The end portion 10 has a top inclined surface 14 which fits with the lower edge surface 15 of the lower supporting beam 4 on an overlying wall element. The end portion 10 thus has a dovetail-like shape, which contributes to the floor element 9 being effectively retained in the wall.
Figure 2 illustrates a floor composed of several prefabricated floor elements 16. These may have ends as discussed above.
Unlike solidly cast floors and ceilings that can carry forces in all three main directions, the joints between prefabricated floor elements will require additional devices to function in a similar manner.
This is solved in a simple and safe manner as illustrated in Figure 2. The elements 16 are provided with a half-high shoulder 17 formed as a half dovetail on one longitudinal edge, and with a substantially axisymmetric abutment 18 on the other longitudinal edge, so that they form blades in a scarf joint when the floor elements are juxtaposed. The mating surfaces 19, 20 of the blades have an inclined angle so that the floor elements 16 are locked to one another through the weight of the elements. In the area of the blade joint, a wedge-shaped joint 21 is provided for curing casting material which consolidates the floor. The bevel angle of the blades may be in the range of 1: 3 to 1: 6, preferably 1: 5.
This solution can take considerable tensile forces through both friction and inclination angle in the joints. The cast material in the joints 21 will take care of shear forces. The blades 17, 18 can be reinforced for strengthening. Floor elements with support or abutment only on one of the longitudinal edges can be used at the floor end against the wall, openings and the like.
