Primary Examiner-Henry C. Sutherland Assistant Examiner-Leslie A. Braun AttorneyEdwin E. Greigg [5 7] ABSTRACT A building construction suitable for forming ceiling floor and wall structures comprises spaced pairs of profiled members, each pair consisting of two U- shaped or channel section members arranged back-toback with their bases adjacent so as to form an 1- section member. The profiled members have flanged webs forming edges against which rest intermediate members located between successive pairs of profiled members.
3 Claims, 4 Drawing Figures PATENTED JAN SHLU 2 0F 3 70 la A 51 5 a Jig BUILDING CONSTRUCTION FOR FORMING A CEILING FLOOR The present invention relates to a building construction.
In the building construction according to the invention, pairs of profiled members which may be supported at their ends and which are spaced from adjacent pairs are used to make floors, ceilings, roofs and walls. Each pair comprises two members of channel or U-shaped section arranged back-to-back with their bases adjacent so as to form a member of I-section, the members having flanged webs to form edges against which intermediate members arranged between two adjacent pairs of profiled members are supported, on at least one of the faces of the structure thus formed.
In the building construction according to the invention use is made of the resistance qualities of rolled steel sheet, by reason of the profile which is imparted to it. This profiled sheet which is of low weight, enables beams of large span to be made to form roofs, partitions and floors.
Moreover, the construction according to the invention, enables the construction of complete buildings without having to use any other profile for the framework.
The construction according to the invention enables the intermediate members to be easily removed to gain access between the pairs of bearing members, so as to effect maintenance thereof or install heat or sound insulating layers.
The profiled member can be made on the building site from strips of sheet which are more easily transportable in the form of rolls than the profiled members of great length.
The intermediate members, which may be perforated, form in association with the inner webs of the pairs of profiled members, a ceiling or wall of the building.
Moreover the different compartments defined by the pairs of profiled members and the intermediate members, form conduits which can be used as ventilating or air conditioning shafts, for the passage of electric wires, for heat or sound insulation, as well as for the passage of various pipes.
The invention will now be further described, by way of example, with reference to the accompanying drawings; in which: t
FIG. 1, is a perspective view, partly in section, of one embodiment of a ceiling constructed according to the invention.
FIG. 2, is a perspective view, partly in section, of an embodiment of a ceiling fitted with a roof.
FIG. 3, is a perspective view of an embodiment of a wall made according to the building construction of the invention; and
FIG. 4, is a sectional perspective view of another embodiment of a roof.
FIG. 1 shows one embodiment of a ceiling constructed according to the invention, which comprises a plurality of pairs 1, la, lb, of profiled bearing members forming beams which are supported at their two ends on other construction members, more particularly walls. Each pair comprises two profiled members 2, 2a which are U-shaped in section and arranged symmetrically one against the other with their bases 3, 3a adjacent, so as to form an I-shaped member. These members 2, 2a have webs 4,5 and 4a, 5a, respectively, which are flanged to form perpendicular edges 6, 7 and 6a, 7a.
Intermediate members 8 formed by perforated plates having flanges 9, 9a which are supported against the edges 7, 7a of the U-shaped members 2, 2a are mounted between each pair of adjacent members. A layer 10 of heat or sound insulation is arranged above each intermediate member 8 in the space between each pair of profiled members.
Since the intermediate members 8 rest solely on the members 2, 2a, it is extremely easy to shift them to gain access to the space provided between the beams.
The intermediate members 8 form a ceiling in association with the lower webs 5, 5a of the profiled members 2, 2a.
Another embodiment, shown in FIG. 2, also comprises an assembly of pairs of profiled members 1, 10, lb, 1c which form a ceiling together with the intermediate members 8. However, a sealed roof which comprises particulate panels 11, the sealing layers 12, 12a, 12b, 12c and a layer 13 of fine gravel is arranged on the upper part of the members 2, 2a,over the webs 4, 44.
According to the embodiment shown in FIG. 3, the pairs of spaced members 1, la, 1b form supports for the construction of a wall. The intermediate members 8 are arranged between the supports and form the internal wall in association with the webs 5, 5a. Behind each intermediate member 8 is disposed a layer 10 of heat or sound insulation. Covering panels 14 are arranged on the outside of the building against the webs 4, of the profiled members.
FIG. 4 shows a further embodiment of a roof made according to the invention which comprises a plurality of pairs 1, 1a, lb, of profiled bearing members forming beams supported at their two ends. Each pair comprises two members 2, 2a, of U-shaped or channel section as has been described above and which are made from galvanized steel sheet.
Intermediate members 15 formed by perforated plates, which rest on the edges 7, 7a of the U-shaped members, are mounted between each pair of adjacent members.
A sealed roof is arranged over the upper webs 4, 4a of the members 2, 2a, and comprises particulate panels 1 1 bearing a layer 16 of heat or sound insulation coated with several layers 12, 12a, 12b, 121:, of sealing material and a bituminous cover layer 13. In this embodiment, the insulating layer is not arranged on the intermediate members but between the upper panels 11 and the sealed roof.
It will be understood that various modifications can be made to the embodiments described without departing from the scope of the invention.
