, 1 ment is formed of precast sections supported around their edges with means for adjusting them to their proper position in the pavement and then permanently connecting them in position.
The invention has further objects which are more particularly pointed out in the accompanying description.
Referring now to the drawings, Fig. 1
shows a sectional view with parts omitted,
of a bascule bridge with the pavement in position.
Fig. 2 is an enlarged plan view with parts broken away showing a portion of the pavement.
Fig. 3 is an enlarged sectional view with parts broken away, on line 3-3 of Fig. 2, showing the adjusting means and the means for connecting the sections to their supports.
Fig. 4 is an enlarged sectional view taken on line 4-4 of Fig. 2. V
i Fig. 5 is a perspective view ofone of the connecting elements forconnecting the sections to their supports.
Like numerals refer to like parts throughout the several figures.
Referring now to the drawings, I have shown my invention as applied to a bascule bridge but it is, of course evident that it may be used for any other form of pavement. In Fig. 1 I have illustrated a moving span 1 with a'bascule bridge supported upon trunnions 2. The floor of this moving span is pro vided with a pavement made up of precast sections 3 of suitable material such as cons crete. These sections are preferably provided with reinforcing members 4; and 5 embedded therein. Each section 3 of the pavement is provided at its edges with a series of connecting elements or shoes 6. These connecting elements have one end embedded in the Secti0n,the other end projecting therefrom. The embedded end is preferably provided with a series of separated fingers 7. This secures a better union between the ele-. ments and the sections. The sections of the pavement are also provided at suitable points around their edges with the adjusting devices which consist of metal blocks 8 embedded in the material of the sections each block being provided with'a threaded opening. Working in the threaded opening in each block is a threaded adjusting member 9 preferably provided with an enlarged head 10. The sections are supported upon longi-. tudinal supports 11 and cross supports 12. The adjustingmembers are arranged to engage these supports 11 and 12.
WVhen the sections of the pavement are placed in position on these supports, the adjusting members are in proper position with their upper faces in alignment and the connecting members 6 in proper position. These connecting members are then permanently connected to the supports 11 and 12.
In the constructionshown, this connection is made by welding the connection 6 to these supports. This welding may be done in any suitable manner. I prefer to make the connecting pieces prong shaped at the bottom. This is done by providing the connecting pieces with recesses 18. (See Fig. 5.) Two of these recesses are made one at each side thereof, the recesses being made by removing the metal so as to provide the recess with an inclined wall at the back thereof. lVhen the sections are properly adjusted, welding material 14 is placed in these recesses and utilized to weld or permanently connect the connecting members 6 with the supports 11 I and 12. The supports 11 are the main floor members carrying the load and the cross supporting members may simply be like secondary members which act to support portions of the sections and transmit the'forces tothe main supporting members. The con necting members 6 are distributed around the edges of the sections and underlie these sections and connect them with the supports, each slab or section being thus supported on all its edges to prevent settlement and tracture.
The sections'or slabs are also supported throughout their length by these metal' shoes or connecting" pieces. The sections or slabs 10 have aplastic fillingmat-erial between them which is preferably filled inafter the slabs are placed in position. The slabs are also provided with a hard wearing surfacewhere the wear takes place. The slabs are 15 separated from the supportsby a clear space; By Welding the shoes or connecting pieces 'to the supports,gthere is secured a stiffening Y effect of a continuous-concrete floor.
g The'use and operation of my invention are as follows:
The concrete slabsaremade of. the proper size andshape and the supports 11 and 12 are placed; position. The slabs'are then placed on the supportsin proper relation to each other" and are'priop'erly' adjusted by means of properly adjusted, ithe'shoes 6 are welded to the supports an'dthe plastic filling inserted reinforced concrete slab, two sets of metal i beams'separate from the slabs, one set of beamsbeing longitudinal and one set being 4 5 transverse, said beams underlyingthe edges of the slabs, metal-shoes projecting from the bottom ofsaid slabs along theedges thereof, and means for welding said shoes to the beams.

A precastpaving system comprisingn reinforced concrete slab, two sets of metal beams separate. from the slabs, one set. of beamsbeing longitudinal and one set being transverse, said beams underlying the edges of the slabs, metal shoes projecting from the bottom of said slabs along the edges thereof,
and means for welding said shoes: to the beams, said beams being separated by a clear space from the bottom of the slabs. 4. A precast system of the kind described comprising two series of supportingbeams,
