(Cl. 52-90) ABSTRACT OF THE DISCLOSURE The roof frame is made in three box-shaped glued prefabricated sections. Each of two side sections has a down weirdly-tapered column portion and a cantilever arm extending from the upper column end or haunch. A polygonal compression block in the hau-nch supports radiallyextending stiffeners to reinforce the angle joint between the column and the cantilever arm. The opposite ends of the central or crown section are bolted to the cantilever portions of the side sections at the building site.
This invention generally relates to a wooden roof box frame consisting of a central beam section which is pitched to the high point referred to as the crown and to column sections which are vertical and which taper outward from their base at the floor line and which at the top of the column section referred to as the haunch are built to incline upward and join the beam section. The beam and column sections consist of flange members at the top and bottom of the section and enclosing plywood cover pieces joining the flange members. Inserted in the core and generally perpendicular to the flange members are web members which serve to stiffen the assembly and, in certain cases, serve as splice members for joints in the plywood cover pieces.
An object of this invention is to provide a roof box frame which is simple in construction, easy to use, Welladapted for its intended purpose and relatively inexpensive to manufacture.
Another object of this invention is to provide a roof box frame in which the joints between the beam and column sections are located at points of little or no bending moment.
Still another object of the invention is to provide a roof box frame in which the frame can be connected to the foundation in a manner which will resist lateral forces and uplift, said connection being concealed and not projecting beyond the sides of the frame.
Still another object of the invention is to provide a roof box frame which at the critical joints at the haunch accomplishes a transfer of all of the flange stress without reducing the stress carrying capacity of the web members.
Still another object of the invention is to provide a roof box frame with an alternate method to transfer the maximum and critical stress at the inside corner of the haunch by the combination of lapping and dapping the flange members and the placement of a piece of plywood on either side of the flanges which contacts the flanges on either side of the lapped and dapped crossing and which is placed diagonally across said joints in such a way that the plywood is loaded in its strongest direction.

In carrying out the invention, referring now specifically to the drawings:
1 is the column section, 2 is the beam section, 3 is the base, 4 is the haunch, 5 is the splice between the column and beam section, 6 is the crown section, 7 is an anchor bolt imbedded in the foundation and projects up through a hole in base block 9 and is provided with a nut 8 access to which is had through a handhole 10. In the column section 1, 12 is the outer flange consisting of a laminated member, 11 is the inner column flange, 13 is the plywood cover for the lower portion of the column section. As indicated, the direction of grain in the member may be set at an angle to increase the shear strength of the column leg, 14 is a web member lying in the core of the assembly which serves to stiffen the assembly and to splice the plywood cover pieces 13 and 20 and other plywood joints elsewhere in the frame.
In the haunch 4, members 15 are stiffener and shear transfer struts being aligned with and constituting extensions of the inner and lower frame members 11 and 22 respectively past the compression block 17. These struts serve to transfer the horizontal and vertical shear directly to the compression block. The compression block 17 is polygonal and receives the end thrust from the square-cut ends of members 11, 15, 22 and the diagonal compression strut 19, each of which ends abuts an edge of the block.
It is of a very strong material such as hickory pecan and is set at such an angle of load to grain that it will receive the full force of the abutting members without indenture. Diagonal compression strut 19 carries its por tion of the load in the compression block 17 up to the bent tension strap 18. The upper end of the diagonal compression strut 19 is cut on a radius and the tension strap 18 is bent to con-form to the radius. Tension strap 18 is secured by nailing, adhesive and/or other suitable means and connects flange members 12 and 21 respectively. Member 20 which is a plywood cover plate for the haunch joint extends around the haunch and serves to stabilize the compression block 17 and the members abutting there. Members 21 and 22 are parts of the column assembly land are glue laminated lumber flanges inclined at an angle similar to the slope of the beam members 2. 23 is the plywood cover plate for flange members 21 and 22.
24 is a beam flange splice bolt, 25 is a beam web splice bolt. These flange members form a cantilever arm extending from haunch 4. Either 24 or 25 may be augmented with additional bolts, timber connectors, and/or other suitable connecting devices. 26 is the column-to-beam section joint. This joint is spaced from the haunch and' from the crown to locate it at or near the point of zero bending stress in the frame. 27, 28, and 29 are column-tobeam web splice members. Each end margin of the beam 3 and column sections are dapped to one-half its thickness and the dapped margins are lapped and secured with bolts for example, as shown in FIGURE 3. Member 27 is fastened to 29 with bolts 25, number 2 is the beam section.
Number 30 is the combined plywood cover. for beam.
flanges at crown and crown splice. The cover plate extends downward below the lower flanges 33 to provide a greater depth of section at the crown. Number 31 is a combined horizontal stiflener and crown splice member which connect the bottom edges of cover plates 30. Number 32 is the uper beam flange, 33 is the lower beam flange. Number 34 is the cover for the beam flanges. The whole assembly, with the exception of the column-to-beam splice, are joined by an adhesive, so that the two splices 26 are the only mechanical connections in the frame.
Referring to FIGURES 8, 9 and 10, the alternate columnto-beam splice detail, 35 is a vertical shear transfer block which has been cut to form complemental seats at mid-height to form the joint and serves to carry the end load from the beam section into the column section and replaces in function the bolts 25 shown in FICURES 1 and 3.
Referring to FIGURES 11, 12 and 13, the alternate crown splice detail, 36 is a horizontal tie which is inserted by dapping the outer portion of the lower beam flange. Members 33, 37 and 38 are filler pieces inserted to block the section for glueing.
Referring to FIGURES 14, 15 and 16 which shown an alternate haunch joint, 39 is the outer piece of the inside column flange, 40 is the inner piece of the inside column flange. Number 41 is the outer piece of the lower column flange, 42 is the inner piece of the lower column flange. Members39 and 42 extend through the haunch joint without interruption. Members 40 and 41 are dapped to permit passage of 39 and 42. Member 43 is a supplementary corner cover which can be used in case the stresses in member 20 become excessive. It may be noted in FIG- URE .14 that member 20 may be placed on a slant to increase its strength at the critical section in this assembly.
In the above the flange members and stiffeners are made of glued laminated lumber, the cover pieces are made of plywood or a similar suitable material. All members are joined by an adhesive except the field joint between the column section and beam section which is effected by bolting, nailing and/or other mechanical fas teners.
The foregoing is considered an illustration only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to falling within the scope of the inven tion as claimed.
