To all whom it may concern Be it known that I, CECIL S. BUMANia, a citizen of the United States, and a resident of the city of Oakland, county .of Alameda, and State of California, have iiivented a new and useful Improvement in Train-Sheds, of which the following is a specification.
This invention relates to train sheds of the umbrella type, and consists in a structure which is composed of reinforced concrete units which are molded at a convenient place, transported to the desired location, erected in position and secured. together by plastic concrete poured into suitable spaces left between the meeting edges of the units.
The invention further consists in the details of construction of the embodiment thereof which is shown in the accompanying drawings, and is more particularly deroof. slabs 18Yare laid. These ledges have 75 lined in the appended claims. a Aslight slope upward and outward from In the drawings, wherein the same referthe midline of the platform. ence characters are used to designate like i The roof slabs 18 are made of reinforced parts in the several views, concrete, and are arranged in pairs between Figure l is a side elevation of a train shed the posts, there being a roof slab on each 30 embodying the invention, partly in section side of the longitudinal center line of the on the longitudinal center line of the strucstructure extending rom each post to the ture; i i next. The inner edges of the roof slabs of Fig. 2 is a cross-section of the same on the each pair abut, and their outer edges proline 2-2 in Fig. l, looking in the direction ject beyond the edges of the platform. Each 85 of the arrows; roof slab `has two longitudinal girders 19 Fig. `3 is aV plan view of a roof panel `made ruiming from end to end, and connected at in accordance with the invention; their ends by cross girders 20. One longi- Fig. 4 is a longitudinal cross-sectioniof tudinal girder is at the inner edge of the the panel shown in Fig. 3, on the line 4-4 slab, and is provided with a longitudinal 90 in Fig. 3; groove 21 in its side adjacent to the mating Figs. 5 and 6 are transverse cross-sections roof slab. The grooves 21 of each pair of of the panel shown vin Fig. 3 on the lines girders register with each other and forin a 5-5 and 6 6 in Fig. 8, respectively; channel into 'which grout is poured to key Fig. 7 is a face View of the top portion of the two roof panels together lengthwise to 95 a post; hold their inner edges in the same horizon Fig. 8 is a cross-section of the arm of tal plane. The outer longitudinal girder the post shown in Fig. 7, on the line 8-.8 of each roof slab is located in alineinent in Fig. 7; and with the ends of the ledges or notches 17 Fig. 9 is a cross-section of a batten strip. of the supporting arms. loo The drawings show a single platform 11, The outer portions 22 of the roof slabs between two tracks 12; but it is understood slope upward and outward from the outer that there are usually several parallel platgirders 19, and are braced by cross ribs 23 forms spaced apart with eitherone or two spaced every few feet apart lengthwise of tracks intervening between adjacent platthe slab. These cross ribs 23 extend across 1x35 forms. The platforms may be made of concrete, brick, or any suitable material, and are usually from twelve to twenty feet wide.
Along the middle of each platform is a row of reinforced concrete posts 13, spaced These posts are T-shaped, with their two arms lll spreading out crosswise of the platform and reaching from about one-half to two-thirds of the way across it. The lower ends of the posts are set in sockets in concrete pedestals 15 beneath the platform, and after being lined up properly the posts are rigidly secured in place by pouring grout around their lower ends to fill the spaces between them and the walls of the sockets. Angle irons 16 are cast on the corners of the posts, extending for a distance of about four feet above the platform to protect the posts from accidental injury by contact with trucks, baggage, or other objects on the platform. The arms 14 are wider than the posts, and have ledges or notches 17 along about twenty to twenty-iive feet apart.
their two top edges in which the ends of the i the panel to the inner girders and stiften the yond the ends of the girders and middle lia portions of the slabs and meet opposite middle points of the ends of the arms 14. The spaces between the meeting ends of the slabs are filled with grout, and the spaces between the slabs and the arms 14 are grouted likewise; and likewise the space over each arm between the ends of the middle portions ofthe roof slabs is filled with grout. Batten strips 24 of concrete are arranged beneath and at the ends of the joints between the ends of the outer 'margins 23 of the roof slabs. These battens are 4held in place by short wires 25 which are looped into the battens, the upper ends of `which project into the spaces between the ends of the roof slabs and are embedded in `the grout.
The posts 13 are each `reinforced by four rods 26, arranged one in each corner, extending from top to bottom, and by loops 27 encircling the rods 26 and spaced about a foot apart for theentire length of 'the fpost. The curved rods 2S follow lthe lower face of each'curved bracket into'the lower part of the arms 14 at their ends. The arms 14 are also reinforced by two straight rods 29 in the bottom region and four straight rods 30 in the top region extending from end to end, and one straight rod 3l in the upper portion of each side ledge. Vertical stir.- rups 32 surround the longitudinal rods in the arms and tie inthe rods 31, Vthese'stirrups being spaced every few vinches apart near the ends of the arms, :thespacing increasing to a foot or soapart at the middle. The ends of the straight rods in the lower region of each arm are bent `up parallel with the ends of the arms, and theends -of the straight rods inthe tops of the arms are hooked under them.
The roof slabs are each reinforced by four straight bars 38 spaced ylengthwise in the top of the main portion of the slab. The beams 19 are reinforced by straight bars 34 arranged lengthwise in their -bottoms, and by bent bars 35 arranged ,in the bottom region at the middle of lthe slab and inthe top region vat their ends. The crosswise ribs 23 are each reinforced by two bars 36, which are arranged in the top region of the ribs at their outer ends, and cross into :the bottom region of the ribs at their inner ends, as shown in Fig. 6.
-These ribs are also reinforced by vertical stirrups 37, spaced about la foot apart lengthwise of the ribs from side to side of the slab. These `stirrups `are yhooked over the straight bars running Ilengthwise ofthe yslab where they are in juxtaposition, Vas
shown in Fig. 4.
The overhanging ,portion `22 of the slab is reinforced by two series of parallel bars, straight bars 38 in Ithe bottom of the slab alternating with bent bars 39, `which lie `in the bottom of fthe slabbetween the -vribs 23 and in the top of the slab across the ribs. Crosswise bars 40 extend from edge to edge ofthe slab -in the bottom at intervals of two 4feet or so, and bent lbars 41 are arranged across the main portion of the slab between the bars 40. Across the middle of the slab thebars 41 are in the bottom, and near the beams '19 they are in the top. rlhe ends of the bars 41 are bent over the outer straight bars 23 and down into the bottoms of the beams, across the bottoms, and .up `the inner sides ofthe beams to their tops, forming stirrups 42. Additional stirrups 43, similar to `the stirrups 42, are provided near the ends of the beams 19 andin the end beams 20. The end Across beams 2O are reinforced and tiedinto the vroof slabs by bars 44 .in the top and bottom, respectively. IThe bars 44 are straight, with ytheir ends bent atv right .angles ,and extending into'the `,ends of the longitudinal beams 19. Short-straight bars 45 are `arrangedover the ends lofqthe straight bars 38 in the ends Aoftheoverhanging portions o'f the slabs. 1
Suitable. ducts are provided for conducting rainwater from the middle'of lthe roof, and the yroof panels are inclined :upwardly and outwardly from the emiddle to cause rain water to iiow inwardly from the edges, as in a gutter, and `keep it fromw dripping oiil the eaves. A
