- ~ - 2089021 DETAILED DESCRIPTION ACCORDING TO THE PREFERRED
EMBODIMENTS
With respect to Figure 1, there is shown a house erected from hollow extruded wall panels 1 and box connectors 2 formed into the walls of the house and sirnilar roof panels 3 and box connectors 4 formed into the sloping roof portions of the house and meeting at a vent cap 5.
0 As shown in Figures 2 and 3 the wall panels 1 and box connectors 2 are of rectilinear form and are adapted to interlock with the inturned ledges 6 of the outwardly extending leg 7 of the box connector engaging in mating grooves 8 in the adjoining wall panels.
The sloping wall cap member or beam 9 is formed in accordance with the invention with an internal chamber arrangement comprising a large central chamber 10 having a closed perimeter and adjoining closed perimeter chambers 11 and 12.
Wall cap 9 depending flanges 12 and 13 are adapted to embrace the inner and outer surfaces of the wall structure formed by the wall panels and box connectors to securely support same on top of the wall.
In addition to the closed chamber arrangement, the wall cap is provided with a longitudinal inner chamber 15 open at one side to the interior of the house and a smaller outer chamber 16 open to ~e exterior of the house. Both chambers 15 and 16 have inturned longitudinally extending ledges 17 for cooperation with a locking member shown as a strip 18 having projecting legs with out turned ledges 19 adapted to interlock with the ledges 17 to close the open side of the chamber 15.
A similar strip or other closure member may be employed to close the outer chamber 16.
In the case of the box connector, there is provided a shallow interior chamber 20 formed by inwardly projecting legs 21 having out turned ledges 22, all within the closed chamber of the box connector itself. The closure member for the open side of the chamber 20 comprises a channel :
member 23 having inturned ledges 24 to interlock with the box connector ledges 22. Integral with this channel member 23 are closed passages 25 and 25' for carrying services such as electrical wiring, telephone, cables and the like as illustrated in Figure 2 which shows wiring coming out of the passage 25 and leading into the chamber lS closed by the strip 18 which covers the wiring but enables access thereto.
As illustrated in Figure 3, to provide a perrnanency to the housing the wall panels and box connectors are adapted to be filled with lo concrete 10' and in effect form casing forms into which the concrete can bepoured protecting the concrete and providing a smooth ascetic exposed surface. In this connection, it will be understood that such wall members will be extruded with a core having a reinforcing filler and a coextruded outer skin to provide the desired structural characteristics.
It will be further noted that with the arrangement shown in Figure 3 the concrete completely surrounds and protects the services ~-~
contained in chambers 25 and 26.
Figure 4 illustrates an extruded beam 26 for closing the lower end of a roof structure 27 formed from the extruded hollow components 3 and 4 embodying the invention. The beam 26 has a central closed chamber 28 as well as axillary closed charnbers 29 and 30. Projecting outside of the closed chambers are flanges 31 adapted to embrace the upper and lower surfaces of the roof structure 27 to attach the beam thereto.
Beam 26 is also provided with an upper chamber 32 having inturned ledges or fingers 33 to interlock with a suitable closure member not shown and a lower chamber 34 opening downwardly and having similar 3 o locking fingers for engaging in the grooves 35 of a closure channel 36 having ventilating openings 37 therethrough.
It will be understood that it is desirable that air be circulated through the hollow cells or chambers of the roofing structure 27 and to this end suitable openings 38 are provided to give access to the chamber 34 and through the openings or slots 37 to the atmosphere.
- 6 - 208902~
Figure 4 also illustrates a connecting sleeve 39 adapted to connect ex~uded beams 26 in end-to-end relation for an extended length of roof panel.
Figure 5 shows a wall cap 40 similar to that shown in Figure 2 having closed hollow chambers 41, 42 and 43 and outer chambers 44 and 45 open at the sides and closed by weather stripping closure strips 46 and 47 adapted to interlock with the respective chambers 44 and 46, said strips having coextruded flexible tips 48 and 49 to bear against the underside of a roof structure as illustrated.
Figure 6 diagrammatically illustrates the use of intermediate roof supporting beams 50 and on opposite sides of a ridge beam 51.
F'igure 7 illustrates another fo~n of extruded beam 57 for capping the roof bearns 50 and having a main closed chamber 52 and an axillary closed chamber 53 and, on opposite sides of the main chamber 52, chambers 54 and 55 opening at one side and provided with interlocking fingers 56 for cooperative engagement with a closure member. This cap beam 57 is also provided with interlocking fingers 58 adapted to interlock in slots or grooves 59 provided in the beam 50 as illustrated.
As illustrated, the roof panel supported on the upper side of the beam 57 may be fastened thereto by screws 60 to hold the panel during the erection process.
It will be understood that the extruded members that are required to carry significant loading and have exposed surfaces to the elements will be formed with a reinforced core and a coextruded skin.
3 o However, it will be appreciated that many closure strips or other extrusions not subject to load may be extruded simply from polyvinyl chloride.
Although various preferred embodiments of the present invention have been described herein in detail, it will be appreciated by those skilled in the art, that variations may be made thereto without departing from the spirit of the invention or the scope of the appended claims.
