8 Claims.

Thisinvention relates to an improvement in structural frame work and more particularly to an arrangement for retaining shelving for libraries, reference files, and also frames for filing drawers, bins, etc;, in buildings where considerable space is devoted to a systematic method of storage. I

The prefered' embodiment of this invention discloses a structure comprisinga plurality of spaced upright supportingmembers, substantially starshape in cross section, which are secured to the floor. Rectangular deck plates are arranged and supported at convenient vertical intervals to any desired height. The structure obtains its lateral support by engaging the walls of the building or only available floor space during process of erec-' tion was the ground floor; In applicants structure, however, the deck plates which are placed in position as erection progresses, provide a safe support for the workman as well as for thematerial to be used in assembling the next tier.

This invention reveals as its principal object a structure for supporting library shelving, etc., having a substantially'integral deck formed by a plurality of deck plates at each floor level.

Another object of the invention lies in the provision of a supporting structure for library stacking, filing shelves, etc., comprising upright members of substantially star-shaped cross section to which deck plates are attached.

A further object of'the invention is to provide, in a-structure for supporting library stacking, means for rigidifying each individual tier against longitudinal displacement.

A still further object of the invention lies'in the provision of a library stacking structure having a relatively small number of parts and which may be easily superposed by additional structure or otherwise altered as desired.

Other and further objects of the invention may be more clearly understood from a consideration of the following specification which is taken in conjunction with the accompanying drawings, and in which Fig. 1 is a perspective view of an assembled Longitudinal support of the .deck plates; and I a Fig; 10 shows a rail attached to a deck plate.

Fig; 3 is a vertical sectional view, showing the connection between deck plates, being taken'substantially on the line 3-4: of Figure 2; Fig. 4 is an enlarged plan view of the star sec-. tionsupporting member or strut, showing the method of attaching" vertically adjacent memberstogether andof securing the deck plates to these members; Fig. 5 is a plan view showing how adjacent deck plates are positicned'with respect to each other and to the supporting members; 5

Fig. 6 is a plan View of one of the deck plates; Fig. 7 is a sectional view'taken substantially on theline l'-i of'Figure 6;

Fig. 8 is an enlarged sectional view taken sub.- stantially on the line 38 of Figure 6;

Fig. 9 represents the fillermember or [shim which is interposed betweentheends of adjacent Referringto the drawings and particularly to Figure 1, a supporting structure is shown consisting of aplurality of star-shaped structural elements or columns which will be generally indicated by the reference numeral. Hi, details of which will be more. fullydisclosed later in the specification. I

The columns are preferably arranged in straight lines at points which define'a plurality of equal rectangles. adapted to be secured to the main or ground floor by means of angle knes' H which are suitably fastened at the floor of each column by boltsl2.. Secured to the upper portion of each column by means of bolts l3 are rectangular deck plates. 40 The ends of said deck plates terminate in down-1 wardly' projecting flanges l6 whilethe sides are terminated by downwardly projecting channel flanges H. Parallel to and a short distanceto V ward the center from the end flanges I5 are a pair of spaced bent upfianges or curbs, {8:which may be formed integral with the-deck plate I 4. "These flanges iii are adapted to form parallel aisles 19 for each tier. Longitudinal openings 26] adjacent the flanges l8 serves as ventilators to conduct fresh air or light from one tier to the next. The surface between curbs l8 may be covered with a composition sheet, block flooring, or any other suitable material 2|. V i

The end portions of the deck l4, commencing The lower. columns are and support shelving .against bending to the I beam section formed adjacent the flange i6 and terminating at the opening 20, constitute the entire storage space of the structure. These portions serve to receive or suitable book receiving units.

At convenient intervals and on both sides of the aisles are located cross-tie rods 22 which may be fastened from a point on the upper portion of one of the columns ID to a point on the lower portion of the next adjacent column on the same side of the aisle. The extreme ends of the tie rods are provided with hooks 23 which are inserted in suitable openings conveniently located in the flanges of the column Ill. Turnbuckles 24 or any other device for adjusting the length of the tie rods 22 are mounted thereon and serve as a means for tightening said rods to the desired tension. 7

It should be pointed out'that between adjacent deck plates there is a narrow gap the width of which is dependent upon the thicknessof the columnflanges which support these plates. In orderto bridge this gap and tie adjoining plates together to form a continuous deck, a shiIhZG has been interposed between said plates which is secured to the adjacent vertical portions of the channel I1 in any suitable manner as by bolts Shims 26 also lend additional resistance by the two reversely disposed channels II.

The deck'plate 33, shown in Figure 10, is provided with curbs 34 which may be attached in sections or may be continuous throughout the length ofthe aisle. These curbs take the form of angle elements which are welded or bolted in place on the plates.

support conduits, water pipes, gas pipes and other conducting mediums 29. 'Since the interposed tiers as well as the adjacent deck plates are mounted on columns in exactly the same manner as the sectionshown in Figure 1, further description of the elements is believed to be unnecessary. Columns It may be continued' upwardly by'splicing additional columns of substantially identical cross section tothe one beneath and may be acccm'plished in many different ways, one of which {is clearly illustrated in Figure 1, 2, 3 and 4 of the drawings. Short'sections of the angle plates 31 maybe secured totheends" of abutting cclumns by means of bolts 32.

The columns I0, shown in the present structure are preferably formed from a pair of oold'or hot rolled structural angles or bent up angles -With the heels faced'off atan angle to both flanges. The faces thus formed are brought togetherand welded or otherwise suitably joined.

one modification of. his invention, he does not,

intend to be limited thereto since it is obvious to those skilled in theart that other modifications' or adaptations may be made without departing from the spirit and. scope of the invention as set forth in the hereunto annexed claims.

Having thus set forth my invention what I claim as new and for which I desire protection by Letters Patent is:

l. A deck plate for structural frames, channel flanges terminating the sidesof said plate, integral curbs formed in said plate, said curbs serving to support flooring material and producing openings outside the flooring area which serve to conduct air and light above or below said plate.

2.-.In a deck for structural frames, a plate, upstanding means spaced inwardly from the ends of said plate, said means being alignable with the corresponding means of the next adjacent plate to provide substantially continuous curbs between which to locate and retain suitable flooring.

3. In a deck for structural frames, a plate, spaced upstanding means formed integral with the face portion of said plate, said means being spaced inwardly from the ends of said plate and alignable with the corresponding means of the next adjacent plate to provide substantially continuous curbsbetween whichto locate and retain suitable flooring.

4. In a deck for structural frames, a plate, spaced flanges running transversely of the face portion of said plate, defining a flooring area, saidflanges being removed from the ends of said plate, and walls defining ventilating openings in said porticnoutside of the flooring area. I

5. In a deck. for structural frames, a plate having a face portion, spaced, vertical flanges formed from said portion, said flanges serving to locate and retain suitable flooring material, and walls definingopenings in said portion outside of the flooring area.

6. In a library stack structure having a plurality of columns, a deck plate secured to each of said columns andserving to prevent lateral displacement thereof, spaced portions of said plate serving to receive and support shelving or book receiving units, and means interposed'between said portions for locating and retaining suitable flooring material. I

7. In a library stack structure having a plurality of columns, a deck plate secured to each of said columns and serving to prevent lateral dis-7 placement thereof, spaced portions of said plate serving to receive andsupport shelving or book receiving units, spaced flanges on said plate for locating and retaining suitable flooring material, and ventilating means between one of said portions and one of said flanges.

8 In a structural frame for library stacks having a plurality of uniformly spaced upstanding columns,'a deckco'mprised of plates, each of said plates being directly joined to four adjacent columns, the end portions of said plates serving to receive and'support shelving or book receiving units, curb means between said end portions for locating and retaining suitable flooring material, light and ventilating means between said curb means and one of said end portions.
