DSJ:af/ 8591 3 DETAILED DESCRIPTION OF THE PREFERRED EMsQDIME~Ts igure 1 illustrates a building structure for which the present invention is particularly applicable.
AS illustrated, the structure has walls made up of prefabricated wall panels 1 joined at the corners by box connectors 2 and intermediate the corners by box connectors 2', prefabricated roof panels 3 ending in box connectors 4, at the edges of the roof and connected intermediate the roof edges by box connectors 4~. The edges of the roof are finished by facia members 5. The wall and roof panels and the box connectors are of hollow rectilinear form and are adapted for interlocking connection.
..;
Such a building structure is now practical with the wall panels 1, roof panels 3, and box connectors 2,2~, 4 and 4' being extruded from thermoplastic materlal and, as illustrated in the enlarged view in Figure 3, being extruded to provide a reinforced thermoplastic substrate 6 having a co-extruded smooth skin 7 overlying the exposed surfaces of the substrate in accordance with the invention disclosed in copend~ng Canadi.an Application Serial Mo.
2,070,079-3. ::

The wall and roof panels are of similar rectilinear configuration having internal webs 8 and end grooves 9 as illustrated in Figure 5. As illustrated in Figure 5,the corner box connector 2 is provided with wall extensions 10 terminating in inturned flanges 11 on adjacent sides 12 and 13 for engagement in the wall panel grooves 9 to form a corner interlock between the wall panels 1.
It will be understood that the connectors 2~ and 4~ will have similar wall extensions and locking flanges DSJ:af/ 8591 q - 7 -2~Q~3 : for connecting the wall panels in an aligned relationship rather than in a corner relationship.

t is desirable that the roof panels be mounted 5 at a slope and, by way of example, the securement of a roof panel at the corner of the building structure will first be described. For this purpose, the wall member in the form of the interlocked corner box connector 2 has mounted on the upper end thereof a cap 14 presenting sloping roof 10 panel bearing surfaces 15 and 16.

The cap preferably comprises an injection molded member adapted to seat down on the top of the corner box connector 2 as hereinafter more particularly described.
15 Intermediate the corners it will be understood the cap for providing the sloping roof panel bearing surfaces may comprise an elongated extruded member seating down on the top of the wall panels 1 and their box connectors 2~.

¦ 20 It will be understood that the building structure may be quickly assembled by interconnecting the wall and roof panels with their respective box connectors and cement or other materlal may be introduced into the hollow wall panels for permanency of the structure and the roof panels may contain insulation if desired.

In the particular context of a building -structure such as described, the present invention provides an advantageous means of securing the roof panels to the capped wall panels to effect a controlled secure connection while affording a means of releasing the connection should the roof panel require replacement for any reason.

In this connection, there is provided an anchor member preferdbly formed of metal generally designated at 17 in Figure 6 provided with a generally flat main body 18 having upper arms 19 which extend parallel to each other in opposite directions and offset by the width of the body 18.

DSJ:af/ 8591 :

~;
~ - 8 -- 2~89023 The arms 19 are provided at their outer ends with outwardly projecting locating finger mounts 20 which are adapted to overlie the corners of the box connector 2 to provide a fixed vertical position for the anchor member when it is inserted into the box connector 2.
:
At the lower end, the anchor is provided with -~-offset parallel orienting arms 21. ~ ;~
:~
The arms 21 are offset substantially 90 degrees from the arms 19 and extend into the corners of the box connector 2 which are at 90 degrees to the corners over which the fingers 20 lie.

The anchor 17 is provided with an upper end -~
extension 22 which is of U-cross section and is provided at -its distal end with aligned pin receiving openings 23 in ;
the opposite walls of the U.

The main body of the anchor 18 is provided with a series of outturned locking tangs 24.

To effect the connection between a roof panel and a capped connector or wall member, as illustrated in Figure 5, the anchor member 17 is lowered into the connector 2 until the fingers 20 rest on top of the corners of connector 2 one finger at the corner of the building structure and the other at the opposite corner of the box connector 2. The anchor is oriented in this position and held in oriented position by the arms 21 extending into opposite corners of the box connector 2 at right angles to the corners over which the fingers lie. The orientation of the anchor is such that the open face of the U-extension 22 faces up the slope of the roof.
The anchor member 17 is then anchored in place in the connector 14 by introducing concrete or the like 25 into the connector 2 with the locking tangs 2g embedded in the concrete.

DSJ :af / 8591 2~0~

The cap 14 has a central opening 26 to allow lt to be sleeved down over the upper end of the anchor 17 into its capping position with the U-shaped end extension 22 standing proud above the bearing surfaces 15 and 16 of the cap.

Cap 14 is provided with outturned ledges or flanges 27 adapted to rest on the upper edges of the bo~
10 connector 2 and depending right angular arms 28 adapted to -:
straddle the anchor fingers 20 and abut against the right angular walls of connector 2, it being understood that sufficient clearance with the concrete 25 will be provided for introduction of the locating and orienting connector arms 28.

The cap 14 is of generally cruciform shape with the extending arms 29 thereof being hollow and carrying the ledge seats 27 at the lower ends thereof.
These cruciform arms are braced by horizontal ;.
triangular webs 30 which overlie the locating arms 28 and : :
the anchor fingers 20.

sy virtue of having the cruciform arms 29 hollow wiring may be sleeved therethrough if desired to run wiring around the roof line. Further, the arms 29 are cut away as at 31 and provided with apertured inwardly projecting`
fingers 32 to provide for an interlock with mating elements of a closure plate (not shown).

The roof panel 3 to be secured to the top of the wall to seat on cap 14 has its box connector 4 provided :
with an opening 33 so that it can be lowered down over the anchor extension 22 to rest on the cap bearing surfaces 15 and 16.

Spring member 34, lllustrated particularly in Figure 5, comprising a plate like member of spring steel or the like, having a central U-shaped slot 35, is then sleeved down over the U-shaped end of the anchor extension 22.
:
Spring member 34 has downwardly and outwardly ~ ~
turned projections 36 which when the spring is slee~ed onto : ::^
3 the extension 22 are oriented one facing the downward slope ~:~
10 of the roof and the other facing the upward slope of the ;
roof. A washer member 37 of steel or the like provided ~::
with a central U-slot 38 is then sleeved down on the U-: shaped anchor end extension 22 to overlie the spring member 34. Washer 37 has reinforcing downturned edges 39 15 disposed in right angular relation to the downturned spring :
projections 36 and projecting downwardly on opposite sides of the spring member. A removeable pin 40 preferable of metal is then inserted through the apertures 23 at the .
upper end of the extension 22 to form a stop against upward 20 movement of the spring and washer members.

The securement of the roof panel or member to the bearing surfaces of the wall cap is then effected by a bifurcated wedge mernber which may be formed as a metal :~:
25 stamping which is generally designated at 41 and shown particularly in Figure 5. The wedge member 41 has a pair of spaced runners 42 pro~ided with reinforcing ribs 43 which are adapted to slide on the interior surface of the hollow box connector roof member 4.
Extending upwardly from the front of the runners 42 are spaced ramps 44 which are joined at their rear as at 45 and connected to the base 46 of the runners by the rear wall 47.
The base of the runners is extended rearwardly to an upturned flange 48 through which forces may be DSJ:af/ 8591 - 11 - 20~9~2~
exerted to drive the wedge inwardly for locking engagement or withdraw it for unlocking engagement.

The upper surfaces of the ramps 44 and connecting surface 45 are serrated as at 49 and the slot 50 defined between the ramps 44 is slightly narrowed at 51 to provide a slight restriction to the passage of the anchor extension 22 therethrough giving the slot a keyhole ~,~
appearance. ~ ~-'''~
To effect the locking or clamping action between the hollow roof member 4 with the facia member 5 removed the roof member is sleeved over the anchor extension 22. , ' Working up through the open lower end of the hollow member , ~ ~' 4 the spring and washer are sleeved onto the extension 22 and the pin is put in place. The wedge 41 is then inserted ;~
into the ,open end of the roof member and beneath the spring member 34.

` The wedge member is then pushed inwardly sliding ,~
on its runners on the interior surface of the roof member 4 '~
with the ramps 44 straddling the extension 22. The inward ' ~'`
movement of the wedge effects movement of the extension 22 -~ ;
up the slot 50. ..
''~
The wedge is driven inwardly until it meets the interference at the slot restriction 51. On further movement, there is sufficient resiliency in the U-shaped extension 22 and the walls of slot 50 to allow the relative movement between the end extension 22 and the wedge to bring the wedge to the final position as illustrated in Figure 4 while at the same time giving an audible click or sna,p as the slot restriction is passed. ThiS click or snap is sufficient to alert the installer that the connection ', 35 has been made with the proper clamping forces between the '' roof member 4 and the cap member 14. ;~

DSJ:af/ 8591 - 12 - ~ 02~

¦ The downturned ends or projections 36 of the ¦ spring member 34 locate in the serrations 49 to bar wedge movement under shocks or vibration.

To release the connection, pin 40 can be removed by means of ring 52 allowing the spring and washer to be `
sleeved upwardly on the extension 22 and the wedge removed by pulling on the wall 48.
`
While the anchor 17 embedded in the concrete filling the box connector 2 should provide sufficient ~-anchorage against lifting of the roof panel under wind loading but if desired, as shown in Figure 7, the anchor member 17 may be further secured by an anchor rod 53 ~
15 extending down into the concrete pad 54 on which the ~ `
structure is adapted to be built and secured.

Figures 8 to 10 illustrate the manner of securing the roof at an intermediate point or intermediate points up the gable of the building structure.

As illustrate in Figure 8, the anchor member 17 is arranged in an intermediate box connector 2' but oriented so the holes 23 thereof are aligned longitudinally of the wall.

In this case a pin 40' inserted through the openings 23 has its end portions 40" deformed to follow the slope of the gable.
It will be understood that the anchor 17 will be secured in position by pouring of concrete into the box connector 2~ it occupies.
i To provide a bearing surface for the roof structure there is provided an extruded end wall cap 55 having closed cells 56 and 57 extending longitudinally thereof and spaced walls 58 projecting downwardly therefrom DSJ:af/ 8591 .:

to embrace opposite faces of the wall panels 1 and box ~, connector 2' of the end wall gable when seated down on top -. thereof. The end wall cap 55 has an opening 55~ through the underside thereof to receive the end extension 22 of the anchor and its pin 40' as the wall cap is seated down on top of the end wall of the building structure.

Further the end wall cap 55 has longitudinally extending chambers 59 on opposite sides thereof with the --chambers being open to the sides as indicated at 60 with the edges of the open sides being turned inwardly at 61 to provide for locking engagement with a suitable mating closure member which may take the form of weather stripping, or other desired closure configuration. Above the chambers 59, the end wall cap 55 is provided at opposite sides thereof with longitudinally extending grooves 62 adapted to receive the inturned flanges 63 of the roof box connector 4 to securely interlock same. The box connector 4 is provided on its undersurface with an 20 opening 64 to accept the pinned end 22 of the anchor with - ~ `-the pin 40~ standing proud above the bottom surface of the box connector.

The outer wall 65 of the box connector 4 is cut away at 66 to expose the pinned end of the anchor and a registering notch 67 is cut into the outer lower flange 68 to allow for the insertion of the metal wedge plate 69.
As illustrated in Figure 10, this wedge plate is provided with a slot arrangement 100 in the form of a cross and is slightly bent intermediate of its length and provided at one end with a handle flange 70.

It will be understood that the wedge plate 69 ~-~
can be introduced into the box connector 4 with the lateral 35 portion of the slotted cross registering with the pin 40' ~ ~
allowing the plate to be sleeved down over the end 22 of -the anchor and over the pin 40' to a point beneath the pin and bearing on the undersurface of the box connector.

~ ,- 14 2089023 The wedge plate may then be pushed inwardly with the bend in the plate forming a camming surface to tighten the box connector down onto the end wall cap and onto the u~ 5 top of the gabled wall to provide an intermediate roof anchor.

Wedge plate 69 is also provided with holes or detents 71 on opposite sides of the slotted cross adjacent 10 to the handle flange 70 into which the end portions 40" of .
the pin 40' may drop when the wedge plate is fully home.

The handle flange 70 provides the means of ' extracting the wedge plate under a pulling force should it 15 be desired to replace the roof structure. -~
