STRUCTURAL COMPONENTS
The present invention relates to building elements (A) for building of framings of joists or walls. Each building element consists of trapezoid thin sheet here called profile plate (1) completed by wooden bars (2), see FIG. Ia. Alternatively the wooden bars (2) may be replaced by any other corresponding material. In this application the wooden bars (2) or when these have been replaced for the purpose by any other material are called connectors (D). In FIGS. Ib, Ic, 2b, 2c and 4b, 4c the connectors (D) consist of metal bars (2′) respectively metal plates (2″) in stead of wooden bars (2). The object of the building elements (A) is to form support for fastening of layer materials (3) according to FIG. 5b, alternatively bars (4) according to FIG. 5c, alternatively boards (5) according to FIG. 5a or in combination of these (3, 4, 5) e g according to FIG. 5d in order to form a frame for load support perpendicular to the longitudinal direction of the profile plates (1), see FIGS. 4a, 4b,4c, coinciding with load support in the longitudinal direction of the profile plates (1). This means that framings of joists and walls designed as mentioned above by frame-action carries perpendicularly to the longitudinal direction of the profile plates (1) at the same time as load support occurs along the strengthened profile plates (1). In this way a framing of joists or wall with load support in two perpendicular main directions is achieved at a four side support of the framing of joists/wall.
Sheet formed building elements, used in framings of joists/walls carry loads in most cases just in one main direction. By the present invention framings of joists/walls carry loads in two major directions. This is achieved with the aid of building element (A) for forming of framing of joists or walls. Each building element (A) consists of trapezoid thin sheet here called profile plate (1) completed by wooden bars (2), see
The main object of the connectors (D) is partly to connect layer material (3) (alternatively bars (4), alternatively boards (5) or combinations of these, see
The connectors (D) are joined to the trapezoid corrugated thin sheet (1) at the other side (10) of its flanges and coinciding with its entire length. The objects of the building elements (A) are to form a support for fastening of layer material (3) according to
A four side support of framings of joists/walls with two main directions as mentioned above make spans compared to corresponding single-spanned framings of joists/walls may be increased at the same load. Thus the competitive ability may be improved.
The dimensions of the connectors (D), the layer materials (3) alternatively the bars (4), alternatively the boards (5) and the profile plates (1) are adapted to each other such that the load support in the two main directions will be as optimal as possible in view of the load of the framings of joists/walls and the spans in the two main directions.
The profile plates (1) are either existing thin sheet profiles at the market or specially manufactured trapezoid corrugated thin profiles especially adapted to the purpose.
The connectors (D) also increase the design height in both main directions which contributes to increased load support. If the connection of the building elements (A) and layer materials (3) (alternatively bars (4) alternatively boards (5) is performed at the building place when forming the framings of joists, the building elements (A) should be supported in the mounting in order to further increase cooperation and load support.
The connectors (D) are joined to the profile plates (1) by aid of glue and/or screws, alternatively nails, alternatively rivets, alternatively welding. The layer materials (3), alternatively bars (4), alternatively boards (5) are joined in turn with the outer sides (11) of the building elements (A) by glue and/or screws, alternatively nails, alternatively rivets, alternatively welding.
The length of the building element (A) in the longitudinal direction of the profile plates is adapted to the size of the room alternatively the height of the apartment or to the distance between the supports in this direction.
The joining (B) of the longitudinal joints of the profile plates, see
Framings of joists/walls formed from the building elements (A) for which patent has been applied for, have hole cambers (6), see
The building elements (A) are easily transported and may be put in piles according to
Known construction elements from the documents mentioned below do not primarily have the ability to form frames for taking up loads perpendicular to the longitudinal direction of the profile plates at the same time as taking up loads primarily also occurs along the longitudinal direction of the profile plates.
