CONCRETE-FORM SYSTEM.

Application filed February 26, 1927. Serial No. 171,231.

This invention relates to wall structures and to apparatus for facilitating the bulldlng of the same. 7

An object of the invention is to provide a bodily portable form system employing a set of standards for staying mutual, ad ustable steel forms, and to provide meanson the standards for effecting a vertical adpistment of units of the forms as the Wall body is built up by poured plastic material.

Afurther object is to provide a form system by the use of which several types of wall bodies may be readily erected, and also enabling the production of walls of diverse thicknesses. I

Additional objects, advantages and features will be'made manifestin the following specification of the herewith illustrated embodiment of the invention; it being understood that. modifications, variations v and adaptations may be resorted to within the spirit, scope and principle of the invention as it is hereinafter more directly claimed.

Figure 16 is a horizontal section of a solid cast wall, and p F1gure 17 is a plan of a cross-webbed walla My present invention is designed to be use- I ful in the casting of several types .of'wall bodies 11,13, C, and D illustrated in Figs. 12, 15, 16 and 1? and the method of casting such Walls Will be made clear in the following exposition of the apparatus. 1

Assuming that a Wallis to be cast upon a set foundation F this is provided at suitable IJOIIltSJVltll stout dead-bolts 2 on. the projected ends of which are securely clamped,

under nuts 3, angle brackets 4 having adjust-ably secured on their top fianges,$upturned horns 5. p

Mounted on and positioned by these horns is an outer and an lnnerseries of standards 7 of any desired, height as determinedby the height of the proposed Wall. The standards may be of steel angle or channel iron stock and when stood on the horns 5 are in a given spaced position from each other transversely of the foundation. Contiguous pairs of the standards, along the Wall, are trussed up by diagonal ties 8 and each standardhas anup and downtrussf). l

Transversely opposite pairs of the stand-- ards are solidly secured by top crown-blocks 10 having open-end cheeks 11 embracing'the standards and being clinched thereon by bolts 12, at anydesired height. .Certain of the bolts 12 have loose wheels 13, Fig.1, to each receive a respective haul chain 141 passing up from its winch 15 which is mounted at arm height on its standard 7 Each chainl i extends into its sprocket 16which is secured on a counter shaft 17 whose ends are mounted in I adjacent blocks 10. Each block supports two shafts 17; these being laterally offset so that the haul chains pass down centrally between longitudinally adjustable spreaders 19 to regulate the distance of hooks 20 on the ends the shaft line and hitch onto bails'l8 having of the bails. The apparatus, just described, V

constitutes a readily erectable, inold supporting frame and mold adjusting means including the hooks 20. e

The mold means includes an'ou'ter series apart by spreaders or saddles 27 having ad-' justable lugs 27 setting against the panels.

Means are provided to buttress the panels against outward pressure and also to relieve the panels from the cast wall when this has sufficiently set. This means includes a vertical ack frame 28 Fig. 7, having set screws 29, in top and bottom lugs 30, to bind against the panel flanges 26 and removably hold the frames inplace. In the frame 28 is a toggle lever 31 having links 32 extending to top and bottom thrust levers 33 which may have rollers 34 to bear out against the adjacent faces of the near standards 7. After the form has been filled and the cement has set then the levers 31 are thrown so as to release the rollers 34'and loosen the panels for elevation by the tackle 18.

Figure 5 shows the system with an interior core device utillzed when a hollow wall is to be cast. This core includes opposite, spaced plates 35 'whose vertical edges have overlapping lips 36, Fig. 3, but when desired only one end may be lipped as in Fig. 4 as when for1n ing. a continuously hollow wall B, Fig. 15. The plates have intermediate reinforcements 37 and their upper edges are overseamed at 38 and connected by bolts 39 to the saddles 27.

' The'plates 35 are relatively collapsible to faeilitate extraction from the cast wall. A cam shaft 40 is journalled on one plate and its cam 41 is turnable to jam against a block 4-2 on the opposite plate. The plates may be pivotally connected at 43.

If it is desired to form a solid body wall C, Fig. 1G,-th e core devices are omitted and the plastic material then fills the form from panel to panel.

WVhen it is desired to build a cross-webbed wall D, Fig. 17, the cores 35 are spaced endwise a distance determined by the desired web W, and reinforcing'bars R may be laid between the core ends.

In Figs. 9 to 12 inclusive, there is shown a very practical wall, and means and method for its creation. In this system the standards 7 are set up as above described'and the panels 25 are arranged in position therebetween 5 stated. lVood studs S are now spaced along on the foundation F at the desired pitch on centers. False panels 50 are set in place along one series of the mold panels and their ends are closed up tight again'stthe contiguous studs S, which protrude inwardly from the panels 50 so as to be embedded in the cast ma terial. Thus, one side of the mold is a continuous panel face of units 25 and the otheris made partly by the false panels 50 and partly by the protruding studs S. The studs may have nails N extending inwardly to bind in the plastic fill and to support reinforcing rods or wires if desired.

The tops of the false-panels50 have outturned rims 51 with clamp hooks 52 to bind on the panel flanges 26, and the outer faces of the members 50 have stifiening flanges 53 V which also serve'as stops'to bear against the set panels 25. After the first course of plastic material has set somewhat thestuds become fixed and the movable panels are lifted by the tackle to the next stage along the studs.

The panels 25 may be of uniform course level along a wall or, as in Fig. 1 the panels -1naybe stepped vertically. In such case an irregular or triangle panel 25 is attached by clips 25 to the next higher panel thus forming a step from an upper course to one below alongthe wall.

From the above it will be seen that I have provided knockdown, portable wall-mold apparatus which can be compactly stacked for transportation from job to job, for repeated setup and use for wall casting; provision being made for adjustment of the elements for casting walls of different thicknesses and different types. V j In Figs. 13 and 14 there is shown applied to a mold unit 25 over which is an adjustable or telescopic section 25 whose face panel slides over the face of the unit 25 to vary the effective length of the combined parts as may be desired according to wall requirements.

and exposing portions of the'studs so that they willbe embedded in the cast-body.

9. The method of erecting a cast wall which includes setting up mold panel sets in spaced opposition, spacing the near ends of the panels of one set, and standing studs in the spaces at the spaced ends so as to pro trude into the chamber of the mold, and cast- A ing plastic material into the mold to embed the exposed portions of the studs.
