Abstract

In a system for erection of load carrying framework for rebuildable houses at least certain load carrying columns (1) and beams (2) in the building structure are so designed that they, in addition to their function to stabilize the house, also can contain all installation conduits which are necessary for the house, easily accessible for inspection, repairs and possible replacement. The columns (1) and beams (2) can have two webs (11 and 21, resp.), a flange (12 and 22, resp.) interconnecting the webs, and two separated flanges (13 and 23, resp.), so as to provide a space inside the column and beam, respectively, with an opening between the two separated flanges. This makes it possible to install conduits/wiring which are always accessible for maintenance, repairs and possible replacement by new conduits/wiring.

Description

System for erection of load carrying framework for , rebuildable houses
* Background of the Invention δ The real cost of a house is the sum of the production cost and the present value of the future maintenance and building costs. This fact does not seem to have been considered since the building activity till now only has aimed at building "production friendly" and thereby reducing the production costs to a minimum. When the time then has come to rebuild the house, for the sake of standard 10 and/or comfort reasons, the costs have many times been so high that it has been more advantageous to demolish the old house and replace it with a completely new house.
The highest rebuilding costs have been the costs for the replacement of the worn out installations for water and sanitation, heat and ventilation, and for electricity, 15 telephone, radio and TV, etc. which are built into the house.
During the previous decade some attempts have been made to make the general layout of the houses more flexible and thereby easier to rebuild. The attempts have given more or less successful results. A common reason for failures has been the choice of material and frame system which has limited the possibilities of 20 removing old installations and replacing them with new ones without distur¬ bances for the inhabitants.

Object of the Invention
It is an object of the invention to remove these disadvantages of the known building systems so as to make re-building possible or simplier.
Summary of the Invention
In its most general form the invention is characterized in that load carrying columns and beams in the building structure are given such a design that they, in addition to their function to stabilize the house, also can contain all installation conduits which are necessary for the house, easily accessible for inspection, repairs and possible replacement.
A special object of the invention is a device or a system for the erection of load carrying structures for re-buildable houses, which include mutually similar columns (1) and beams (2). The system is characterized in that each of said columns and beams is formed with two webs (11 and 32 respectively), a connect¬ ing flange (12 and 22 respectively) and two separate flanges (13 and 23 respec¬ tively) so as to provide a space inside the column and beam respectively with an opening between the two separated flanges, thereby making possible to install conduits which are always accessible for maintenance, repair and possible replacement by new conduits.
The beams and columns which are used in the invention are preferably steel beams and steel columns respectively, but corresponding beams and columns of wood can also be used for comparatively low buildings.
Short Description of the Drawings
The following is shown in the enclosed drawings:
Figures 1 and 1A show a steel column and a wooden column respectively accord¬ ing to the invention in a perspective view and in two sectional views A and B, respectively. Figures 2 and 2A correspond to Figures 1 and 1A respectively, but show a steel beam and and a wooden beam respectively according to the invention. Figures 3 and 3 A are sectional views showing the structure of the steel frame and wooden frame respectively with columns and beams, and the connection of columns according to Figures 1 and 1A respectively to the outer wall in two sections A and B, as well as the connection of beams according to Figures 2 and 2 A respectively in sections C and C.
Figures 4 and 4A correspond to Figures 3 and 3A respectively, but they show examples of conduits to the various installations in a column and beam with branches to floor structure.
Description of Preferred Embodiments
Some presently preferred embodiments of the method and device according to the invention will be described in more detail in the following with reference to the enclosed drawings.
Figure 1 shows a column 1 of steel in elevation and cross-section. The column has two webs 11, a connecting flange 12 and two separate flanges 13. Between the two webs of the column there are provided rods 14, at a desired center distance, for attachment of conduits and the like. Each flange 13 consists of a part 131 for connection to an outer wall, and a part 132 for attachment of fire-protecting coating and a heat insulating material. The column also has openings 15 for connections to floor beams 2.
Figure 2 shows a steel beam 2 in elevation and in cross-section. Like the column, the beam has two webs 21, a connecting flange 22 and two separated flanges 23. Between the two webs of the beam there are provided rods 24, at a desired center distance, for attachment of conduits and the like. Each flange 23 consists of a part 231 for bearing in connection with hollow floor blocks 3, and a part 232 for attachment of fire protecting covering and inspection covers. Further, holes 25 are provided in the two webs of the beam for connection to the holes in the floor blocks.
Figure 3 shows a section of a building framework of steel having columns 1 and beams 2, wherein there is space available outside the opening 15 of the column for attaching the beam to the column by means of splicing pieces 26. Conduits in the column can be branchaed into the beam through the opening 15. The con¬ duits/wiring in the beam can be branched into the floor structure through the openings 25 provided in the two webs of the beam. The sections A and B show the connection of the outer wall to the column. Since the two separated flanges of the column face outwards, the conduits in the column will be accessible from the outside of the facade of the house after removal of the fire-protecting covering 5. Sections C and D show the connection of the floor structure to the beam. The conduits in the beam are accessible from below after removal of the fϊre-protecting covering 6, because the two separated flanges of the beam are facing downwards.
Figure 4 shows a section of the steel frame and examples of conduits to the various installations in a column, beam with branches into the floor structure. The conduits/wiring which have been installed in the floor structure are accessible from above at the respective installation part.
The embodiment according to Figures 1A-4A is fully analogeous with the one shown in Figures 1-4, with the exception that wood has been used instead of steel for the building structure and that wooden beams etc. have been used for the floor structure instead of hollow concrete blocks. For example, the column webs 11 may be made of fibre board or other suitable material, and the connecting flange 12, as well as the separated flanges 13, may consist of wooden joists. The same is true for the web 21, connecting flange 22 and the separated flanges 23 of the beam.
The invention is, of course, not restricted to the embodiments which have been specifically shown and described. Many modifications and variations can be made within the scope of the appended claims.
