8 Claims. (Cl. 108-6) This invention relates to building structures faced on one or both sides with a reenforcing having floors, roofs, walls or the like, composed surfacing layer 5. While this surfacing layer or of preformed building slabs or units adapted to layers may be of any desired material it is preibe laid edge to edge to build up a layer of suberably of some such rigid material as cement stantially uniform thickness, and particularly asbestos. Such-slab construction is board-like 5 pertains to roof decks composed of preformed and rigid, thereby being load sustaining so that insulating slabs laid edge to edge with a means they may be walked upon and adapted to sustain interposed for securing the adjacent side edges heavy loads. of the slabs in relative position and providing When assembled the opposite ends of the slabs w for contraction and expansion between said slabs. rest upon slightly less than one-half the width 10 The practice heretofore has been to provide of the face of each respective beam. plates extending over the joint between adjacent Between the side edges of adjacent slabs, are slabs and then secure the plates in place by bolt expansion and contraction member 5 formed means extending through the slabs and plates. from any suitable material, but preferably w This, of course, necessitates providing ,holes in stamped from relativelythin flexible metal such the slabs and plates that must be aligned in regas sheet metal. This member is formed with istration for insertion of the bolts therethrough, base portions l and 8, oppositely disposed, with as well as requiring time for applying nuts and an intermediate rib 9 disposed therebetween. tightening them on the bolts after said bolts s ri may b c nveni ntly f rmed by e di have been inserted in place. The slabs are weaka portion of t e Strip back p tse a d wi h 2G ened by these bolt receiving holes, and are rigidly the retroverted portions spaced apart to provide secured together with no provision for contraca groove It.

The slabs may be of any he hoo ed d a number o s ts i ay be construction, but are preferably constructed to P v thereby d d g th ge into a numprovide for thermal insulation.

The instance they are typified by a composition sheet ps are assembled between the S e e e of 3 having a relatively thick core l composed of adjacent slabs with the base and web seated re- .55 one or more layers of any fibre composition board p iv ly against ne of the ases and the rib of member 6, and the hook on the clamp engaging the edge of the base on member 6. When the clamps are thus assembled on the members 6 between the slabs, the tongues l may be hammered or bent upon the margins of the slabs, the alternate tongues being preferably bent back in opposite directions.

After the roof deck or other structure is thus formed, it may be covered with any suitable covering material. vention is typified in connection with a roof deck. Accordingly, the decking may be covered with any conventional weather surfacing material either in the form of built-up roofing, roll. roofing, strips or individual shingles. For example, the decking may first be mopped with a layer iii of hot asphalt, the mopping layer is overlaid with sheets of roofing felt H, the edges of the sheets being overlapped. A second mopping l8 of asphalt is applied over the roofing felt sheets, and then surfacing material in the form of slag or gravel or in the form of granular surfaced cap sheets is applied over the second mopping layer.

In the construction of the expansion and contraction member 6, it will be noted that the base portion 8 is in a plane slightly below the plane of the base portion 1. Base portion 1 of the expansion and contraction member and base portion l2 of the clamp II are in the same horizontal plane. sheets 3 are properly aligned in the same horizontal plane so that adjacent edges will not be raised one above the other. If the clips be inserted between the sheets directly over the I- beams, shims may be inserted beneath base portion 1 to provide a support on the beam in alignment with base portion 8. Or if hook portion I3 also seats on the I-beams, shims may be placed under both base portions 1 and 8' to provide supporting contacts in alignment with portions l 3.

If on the other hand, it be not desirable to have the composition sheets in alignment, the base portions 1 and 8 may be in the same horizontal plane, with the base portion l2 of the clip II in a plane slightly above. This will also, of course, raise the end of one slab slightly above the .other, that is, to an extent equal to the thickness of the base portion l2. Since these clips, however, are relatively thinabout the thickness of sheet metal-this displacement of the adjacent ends of the sheets 3 is not objectionable. They are ordinarily spaced at intervals and employed only between the I-beams, and accordingly do not need to be supported on the I-beams but there may be constructions in which it is de sued to have them resting on and supported by the I-beams, as they are, of course, of general zsiicllggtation and may be employed wherever de- In the construction above described th d of the adjacent slabs are slightly spaces. frifri the rib 9 to provide spaces in which the mopping material may flow and fill in the spaces on both sides and above the rib. The mopping material is yieldable and expansion and contraction is thereby further provided. The rib 9 reenforces the member 6 thereby permitting lighter gauge metal material to be-used. The member is sufficiently strong to serve as a support member for the slabs.
