REINFORCED-CONCRETE CONSTRUCTION.

Specification of Letters Patent.

Patented April 13, 1909.

Application filed March 14, 1908. Serial No. 421,170.

Improvements in Heinhneed-Concrete Con struct1on, of which. the following is a specification.

h'ly invention relates to a reinforced concrete construction, and pertains especially to an improved reinforced hollow concrete wall for buildings.

'ings, 111 which Eigure 1 1s a perspective view showing The object of the invention is to provide a monolithicstructure of concrete, which shall have air spaces or fines, or be otherwise made hollow a great part, which shall be of much lighter weight than the ordinary, solid con crete walls, and which will accordingly re; quire less expensive foundations; yet at the same time will possess all the attributes of strength, rigidity and permanence.

The invention consists of the parts and the construction and combination of. parts as hereinafter more fully described and claimed having reference to the accompanying drawthe wall construction especially adapted for heavy walls and large buildings. Fig. 2 is a similar view, showing-my wall construction adapted for lighter buildings.

In practice, the invention may take either of two forms, as shown in the drawings; one of these forms, represented by Fig. 1, being especially adapted for heavy walls and large buildings, and the form or type represented in Fig. 2, beingaarticularly adapted for dwellings and smaller buidlings where a reinforced structure is desired, but where lightness and eheapness are important features.

By reference to Fig. 1, A represents my improved wall construction of concrete having the vertical reinforcing rods 2, the horizontal reinforcing rods 3, the cross-stays 4, and the vertical fines or hollow spaces 5. In.

the construction of this wall I use a core form 6, as shown in Fig. 1, for the )urpose of forming the fines 5 and in the wall construction I employ panels 7, movable sup orts 8, and connecting bolts-9, and PlOCQGl in the following manner: 'Ihe panels 7 are each about eighteen inches high, and cut to any required length. They are held in position by the movable supports 8, which latter are made of two pieces of lumber 1 2: 4 x 4 nailed together with a piece x 2 X 4 between them at each end, thereby leaving a half inch slot for the bolt 9 to operate in.

After the footings are in place, and the building of the wall is to begin, two panels are placed on the footings opposite each other around the entire building, being held the required distance apart by suitable spacing blocks or pieces, not here shown. The mow able supports 8 are placed the requisite distance apart to hold the panels in position. After the latter are set up on the footings and suitably supported, the core forms 6 are placed between the panels at the required distances apart, corresponding with the desired spacing of the vertical flues 5'. These core forms are preferably made in the manner shown, of gal vanized iron, with a couple of hand'holds 6 at each side to permit of their being easily removed. The inside of the core forms 6 are then filled with damp sand, and the space around them filled and tamped with con crete. As the work progressesthe core forms are pulled up, leaving the sand, which prevents the concrete from filling the hollow until it has had time to set.-

' When the first set of panels has been filled around the building, the movable supports 8 are raised, the lower panel released and placed above the remaining panel between the supports, appropriate spreaders inserted, and then bolted in posh tion, to form a trough or bench in whi'chthe concrete is dumped and tamped around the core forms, as described in the first instance. Every time a fill is made around the building, or to any desired length of the wall, the same process of raising and resetting the panels is repeated, until the wall or column is carried up the required height. Each time the cores are lifted they are again filled with sand, .so that when the whole wall is completed there will be a series of columns of sand in each; flue-'5. These sand cores or columns may be removed after the building is up, by means of holes 10, Fig. 1, left in the inside wall at-suitable intervals. In rearing the wall, these holes may be formed by placing two vertical pieces of thin board or tin 7 between the core form (5 and the inside panel 7 (as the work of filling is going on) with a suitable packing of sand between these boards; the boards being drawn up ward and used over and over again, as the work progresses, leaving the openings 10 communicating with the fines 5. Later, the send cores may be washed out with a. hose passed in through the holes 10. This send iney then be gathered up and used for nlsste ing; hence there will be no waste of During the upbuilding of the well, the horizontal reinforcing rods 3 are lend in at suitable intervals, and arranged on. each side of the lines 5, as clenrly shown in Fig. 1.

'2. well oi tns construction is light and stron end has the advantage of :t hollow inonoithic structure with air spaces, lllztlithe wells worm in cold weather and cool inhot weather, end proof against moisture. This structure obtained entirely without the use oi expensive hollow tiles. ll'icse wells being, hollow, and coinpurstively light,

require it less toundution; :Nnl consequently,

- IUl'llllllg adopted tor ligl l there is o saving of material and expense 'ui/er 'tl eordinsr solid rcinlorccd systems have shown u structure ter ouildings, in which I use practically on y 2. single well with reinlorcing ribs, instead ol doublewell. es in Fig. 1, with .eonne .ting ribs. 'lhus, zliS soon inllig. 2, it represents thewull, with the later ally-extending reinforcing ribs (1 these ribs both horizon telly end vertically, shown in 2, and separated by wed geslisped pdclccts or hollow sfmces 5 in this structure I use the some system of vcrtieel reinforcingburs 2", the double sot-oi horizontal reinforcing bin-s3, end the connecting: stuys l". The method of Pi'OCQllUlO in building this well is substantially the some, as lrrr {is the use of the piurels 7, etc, concerned, except thnt instead oi using core forn'1s,us' (j l orn'ploy ii '-.vedge-shepcd ore "S", if 2, which; hitter cores oreluid' in against the inside of the inside panels, and the-concrete necked in :rrornrd these wedges. Atterthe well is set, and the'psriels removed, the wedges ere readily iron-loved.

apart, and at the crossing of these webs at the time the well is going up, 2210 inserted dovetailed blocks 11, which remain e'n'ibedded in the linished well, and permit the turring strips to be nailed thereto. The letlis are then nailed to these turring strips, and when the plaster is put on the hollow spaces in the wnllnrc inclosed. If desired, thcsc hollow spec-cs 5 may be connected in either vertical or horizontal scr'ics, d8 indicated art 123, by the use of :r \\'((l:(.-5llttl)0ll piece o'l' wood placed in proper position between any two adjacent wedges 6 W hen the wedges 6 are rcinoved, these connecting wedges ins-y be lUlO'OliOll out, leaving the llucs connecting the pockets ln thiswny i get at hollow rciniorccd concrete well with vertical lines, just 7L3 i do in Fig. 1. This well can also he made any desired thickness, and the hollows behind the plaster nniy be regulated in sizc and depth to meet requirements.

liming thus described my invention, what I claim and desire to secure by Letters Putcnt is l. The method of concrete construction, which includes building; up a concrete wall between movable side panels, and forming:

hollow S',1}L('PS in the will by placing; therein hollow open ended core forms, filling these core terms with sand, rinsing" tlicse core forms and nuiintsiningthem fill ed with sand, looting; the send in the well while the construction of the some proceeds, placing verticol spaced pieces in the wall between the core we and the side panels as the wall progrosses, and placing it pecking ol sand hotwccn ssid pieces, to l'orni side openings which connect with the vertical spaces and subsequently removing the sand through said side openings in the well.
