iamcter iiesorihsri of Fig. 2) representsthe beam merging with the door, the parts shown in section 1n Fig. 3 being enlarged somewhat to better bring out the relation of the several elements of our invention. Parts shown but not re erred to ere Well known in the artaud require no description in the present connection. As shown iu the drawings, the en chers or clasps are disposed across the ispjoint between the sheets a, and distributed to the required number along the joint. The sheets are thus effectively held against, displacement, and economyfin the use of the sheets results. In the ismsntling of tbe falsework, the sheets are readily pulled away from the clasps, and the parts may be used again for the nextjob.

Having described our invention, what we claim is: Y-

1. A concrete-Hoor decking comprising series of sheets of, thin material with adjacent edges overlapped, clasps having each a medial or body portion interposed between the sheets and across the lap-joints formed by the sheets, and outer spring arms engug img the outer feces of. the respect-ive sheets und clasping the same to the medial portion, and corrugated sheets supporting the overlapped 'thin sheets, the bottom series oit arms of the olas being adapted to rest in the depressions ormed by the corrugetions.

2. A concreteloor decking comprising .series of sheets of thin materiel with zuljiu cent edges overlapped, clasps having each a medial or body portion interposed betr-reen the sheets and across the lap-joints formed by the'sheets, and outer spring arms engegJ ing the outer 'faces of the respective sneeis,

and clasping the seme to the medial. portion, eind corrugated metal sheets supporting the overlapped thin sheets, the bottom ies of arms ot the clasps engaging the corrugated sheets.

3. A concrete-50er decking comprising series of sheets of thin material with adjacent edges overlapped, clasps Aformed of s single strip of metal and having each a media-l or body portion interposed bet-Ween the sheets and disposed across the lap-joints between the sheets, and outer spring arms extending in opposite directions from the opposite ends of the medial portion and terA minating a suitable distance beyond the ends of the medial portion whereby the sheets are guided into position between the arms4 and medial portions7 and corrugetml sheets of metal for the support of the thin sheets the bottoni series of arms ci the clasps rest4 i ing on the corrugated sheets.

in testimony whereof we :illix our siguetures, in presence of two Witnesses.
