Definitions

  • the principal object of the invention is the provision of a novel and improved structure of the type described in which, by an ingenious structural modification of the sheet steel base, a saving is effected of from about 20% to 33 /s% in metal costs, while at the same time there is maintained the structural strength and dimensional adequacy of the seating arrangement.
  • novel arrangement provides an improved appearance and more convenience in welding and painting the structure.
  • the construction permits a more convenient location of the seat posts or brackets, ,provides a better footrest, and reduces the amount of space required in storage and trucking.
  • the invention contemplates the provision of a stepped grandstand structure, which instead of a conventional rectilinear tread and riser arrangement, the actual horizontal tread portions are narrowed to a minimum width necessary for providing adequate transverse walking decks, and the riser portions of the deck structure are correspondingly widened and disposed in inclined or sloping positions.
  • the seat posts are very conveniently attached to the in clined deck portions, and the sloping metal surfaces are convenient for footrests for the occupants of the seats.
  • the usual bleacher seats without back are disposed about twenty-four inches apart on centers, and thus the walking deck portions were correspondingly twenty-four inche wide.
  • the usual thickness of metal on the old twenty-four inch decks was A inch.
  • FIGURE 1 is a partial view in perspective of a grandstand structure embodying the principles of the invention
  • FIGURE 2 is a somewhat more diagrammatic view in side elevation of a stand similar to the one shown in FIGURE 1;
  • FIGURE 3 is a fragmentary view on an enlarged scale and partly in vertical section of the grandstand;
  • FIGURE 4 is a transverse vertical sectional view taken substantially on line 4--4 of FIGURE 3;
  • FIGURE 5 is a fragmentary detail view taken on line 5-5 of FIGURE 1.
  • the novel grandstand is given the general designation in the drawings and comprises a basic framing structure which includes stringers preferably in the form of I-beams 11 disposed in inclined positions and spaced along the width of the grandstand 10 as clearly shown in FIGURE 4.
  • the front end of the stand may be at a slight elevation above the ground, in which situations the I-beams 11 need not be bevelled or truncated at their forward ends.
  • the first row of seating occurs at substantially ground level and therefore the forward ends of the beams 11 are cut away as at 12 to align with the level of the ground surface 13, which surface may of course be reinforced by a concrete or other paving layer to aid in supporting the stand upon the soil.
  • the rear and intermediate portions of the stand It] may be supported by any suitable structure as typically represented by the posts 14 in FIGURE 2.
  • the sheet steel decking structure 15 Disposed upon the spaced I-beams or stringers 11 is the sheet steel decking structure 15 which would, in the conventional structures, be bent or angled to provide alternate risers and treads standing at right angles to each other as in an ordinary stairway.
  • the deck structure 15 is serially bent at wider obtuse angles to provide alternate inclined riser portions 18 and tread or cross walkway portions 20.
  • the decking may be made in sheets of suflicient rearward extent to bridge two or more rows of seats or the width may be determined by the spacing center-to-center between adjacent rows of seats.
  • an overlap joint structure between adjacent transverse deck sheets is shown at 22 beneath the first seat 24 and also a junction is shown adjacent the last row beneath the seat 25; however, beneath the second seat 26 the deck sheet is continuous.
  • the joints between adjacent tranvsersely extending deck sheets might occur intermediate the walkway portion 2t but in the present illustrated example, the joints are arranged beneath certain of the seats, and in such a structure common fastening means such as self-tapping screws may be employed to secure the overlapping edges of the deck sheets together and to secure the base brackets of the seat posts in place.
  • FIGURE 3 of the drawings where the seat 24 is bolted to a plate 28 carried by the vertical post 29 which is provided with an angled bracket plate 30 at its lower end, the :angularity of the plate corresponding to that of the inclined rise-r portion 18 of the decking.
  • the edges of the adjacent plates 32 and 33 are overlapped as clearly shown and the same self-tapping screws 35 may be employed to join the plates and also to secure the bracket 30.
  • each of the I-beams 11 Beneath the riser areas of the decking aboveeach of the I-beams 11 are secured the angle plates 40. An inclined portion 41 of each of these plates is secured upon the underside of the lapped junction areas of the plate edges; and conveniently when a seat post 29 occurs above one of the I-beams 11, the same screws 35 could be used to secure the angle bracket 40.
  • the vertical arm 42 of each angle bracket is directed downwardly and abuts the top flange 44 of the I-beam 11 as clearly indicated in FIG- URE 3.
  • an extra bracing measure is afforded for those portions of the decking 15 which do not come into contact directly with the flange 44 as in the case of the bends 45.
  • the plate 33 is extended horizontally and mounted upon a framework 60 which may conveniently comprise wooden strips such as two-by-fours and the sheeting may be secured thereto as by means of the screws 62.
  • a further sheet element 65 may have its forward inclined edge secured to the last inclined riser portion 18 and this sheet 65 may be bent downwardly as at 66 and suitably secured to the end of the I-beams 11 as by means of the plate 67.
  • a bracket 70 may be secured to the horizontal portion of the final sheet 65 to receive a railing post '72 which also maybe braced by means of the strut 73 bolted to the final riser area 18, and the railing may be completed in suitable fashion as suggested by the elements 74.
  • the deck sheeting may be made in any convenient obtainable areal dimensions and if adjacent strips are to be joined along rearwardly extending lines such as suggested at 80 in FIGURE 1, such junctions may be conveniently effected as suggested in the fragmentary detail view of FIGURE where a sheet 132 has its edge abutted to the edge of a seat 133 as at 134.
  • a series of small cleats 135 may be secured to the lower portion of the edge of sheet 132 as by means of the screw 136 and the projecting portion 137 of the cleat 135 will underlie the edge of the deck sheet 133.
  • the sheeting may be further secured as by means of a welded joint suggested at 138 or at 140.
  • the gauge of the metal sheeting may be reduced with an attendant saving in costs.
  • a grandstand structure comprising a supporting framework, a stepped sheet metal deck structure, and seating means supported thereby, said deck structure comprising alternating tread and modified riser portions, said tread portions being somewhat narrowed to provide only the transverse walkway width needed for comfortable passage therealong, said riser portions being inclined to provide forwardly and downwardly sloping areas, and means securing said seating means to said sloping riser portions only of the deck.
  • said framework includes stringers inclined from the front of said grandstand structure upwardly toward the rear thereof, the angled junctions of the forward edges of the riser portions and the rearward edges of the tread portions resting upon said inclined stringers, and supplemental supporting brackets for said deck structure comprising strips each secured along the underside of a riser portion and having a rear end portion bent downwardly into abutting contact with said stringer.
  • the grandstand structure as set forth in claim 4 in which the seating means comprises seats secured to the upper ends of vertical supporting posts, and common means for securing the deck sheets together within the sloping riser areas and for securing the lower ends of the posts to the riser portions of the deck.
  • the grandstand structure as set forth in claim 2 in which the deck structure is made of a plurality of sheets, the adjoining edges of which are overlapped and secured together within the confines of the riser portions of the deck structure, and in which the seating means comprises seats secured to the upper ends of vertical supporting posts, and common means are provided for securing the deck sheets together at the riser areas, for securing the lower ends of the posts and the supplemental supporting brackets to the riser portions of the deck.
