SIGNORS TO SPR-GUL CONSTRUCTION CORPORATION OF ILLINOIS METHOD AND APPARATUS non CONCRETE WALL oons'rnuc'rroiv Application filed March 26, 192 8. SerialNol 264,620.

I This invention relates to the construction of concrete buildings, particularly to thecon- 'struction of the type of buildings wherein the floors of concrete slab construction are carried on a reinforced concrete frame which is enclosed within a monolithic concrete wall. Such a type of construction is sometimes employed in cold storage buildings and the like, wherein it is desired to insulate the enclosing wall against transmission of heat.

The invention has to do with method and means for the construction of the enclosing wall, or curtain wall as it is sometimes called,

with the use of slip forms; As will be under-,

stood, slip forms are of a type in which the form panels, which constitute the mold s11.- faces between which the concrete is poured and shaped in the building up of thewall, are

arranged so as to be elevated from time to timein the proper position to continue the mold cavity on upwardly from portions of the wall already poured and set, to receive additional'pourings of concrete. v

A general object of the invention'is the provision of improved method andmeans for the construction ofcurtain walls in the dc sired association with frame and floor construction which is already in place.

A. more particular object is the provision of such method and means whereby the our tain wall may be constructed accurately and rapidly by the employment of slip forms, withoutinvo-lving complications in the manipulation or construction of suchforms.

Still another object isthe provision of such method and means whereby the curtain wall.

may be constructed with suitable provisions for installation of insulating material.

Other and further objects will be pointed out or indicated hereinafter, or.will be apparent to one skilled in the art uponan understanding of the invention or its employment in practice. I g

In the accompanying drawing forming apart of this specification we illustrate apparatus and construction wherein the invention may beembodied and by which it may be practiced, but itis to be understood that these are presented for purposes of example only, as the invention is not limited in embodiment COMPANY, OF CHICAGO, ILLINOIS, A

or use to the particular forms of apparatus herein shown and described.

in said drawings 1 Figzl represents anelevational view of a portion of a building frame with form guides in place; r

Fig.2 represents a transverse elevational view of an embodiment of our improved slip form in association with a portion of the building construction, and p Fig. 3 is horizontal sectional detail taken on substantially line 33 of Fig. 2. i

In the construction of buildings with mono-' lithic concrete walls,.it is frequently desirable to erect the frame and place the floors before building theenclosing walls; Such a has presented a 'ditficultproblem, involving various considerations not encounteredin the erection of such Walls in advance of theplacing of the associated'floors. The present invention provides a solution of this problem in such fashion that the customary advantapges of operation with slip forms are availed O apparatus employed,re sort will be had to the example illustrated in the accompanying drawing. We will assume-a situation in which the building frame portions consisting V of the colums C and the floor portions F ineluding the beams and slabs, have been erected to a suitable height, and it is desired to close this frame portion with a curtain wallwhich-is'to be heat insulated. In the forming of the floorslabs, holes 10 are pro, vided in the slabs at suitable intervalsalons I I b their outer margins, same being formed, for

example, by the insertion of short sections of.

Fora description of the method and the pipe in the slab forms before the floors are poured. As a preliminary to the erection of the wall, vertically running form guides 11 are arranged at the desired horizontal intervals between the floors and atthe outer margins thereof, said guides being lined up vertically from floor to floor. Each of. these.

' guides tightly against the slabs or beams.

The slip forms comprise a plurality of frames made up of the vertical members 16 which are rigidly connected in parallel. relation ship and carry the form panels 17, the handling platform or-runway l8 and thejack' screws 19. The form panels 1? are spaced apart transversely, to aiiord the mold cavity in which the concrete is poured to form'the wall VI. The jack screws are adapted for cooperation with clamps 20 which may be affixed to the jack rods 21 that extend vertically in the wall and constitute the supports on which the frames and their carrying portions may be elevated from time to time by operation of the jack screws. The frames are adapted to have lateral support and guidmice on the guide members 11, such as to maintain the forms in the desired vertical position against't-he'weight of the handling platform. Wear strips 22 are carried by the frames for bearing cooperation with the guides. desired alignment with the guides and to support them above their points of support on the jack rods,'the frames are provided with movable guide yokes which include the jaws 24 which are pivotally connected to the frames at 24 and are adapted wheuin their extended position to straddle the guide struts li r The guide yokes are maintained in cooperation-with the guide struts by bolts 24* which are removable and which carry rollers 24 adapted to ride on the inner side of the guide strut.

The slip forms being thus associated with the guides and the form panels being thus nuintained in the desired position, concrete is poured in the mold cavity and suitably disbuted and allowed to set to the desired nrmness. Thereupon tl e forms are elevated to the desired extent by manipulation of the ack screws, to extend the mold cavity on upwardly from the portion of the wall which has been poured. Operation continues in this fashion, so that the wall is gradually built up by addition of new pourings'of concreteat the top; As one of the guideyokes is brought to a position near the upper end of its cooperative guide 11,the bolt 24% is withdrawn, and the guide jawsswung back In order to hold the frames in the to a position where they clear the margin of the floor, as illustrated by the next to the uppermost guide jaws 24: in Fig. 2. Upon further elevation of the form to a position where this guide yoke may be engaged with the next guide strut, the Jaws are swung out again and the bolt and roller replaced, as illustrated by the topmost guide yoke in Fim 2. Thus the upward'progress of the forms'is continued throughout the desired height of the building, the forms at all times being afforded the proper support and guidance to insure the wall being built up in the desired .plumbpositionandin the desired relationshi to the frame and floors. The space S afforded between the inner surface of the wall Wand the margin of the floor is left for the reception of insulating material, such'as slab cork, or'other desired inner surfacing for the wall. Guides 11 which have been passed by the forms, may be removed and reinstalled above the forms.- The holes 10 may be either closed by grout or may be utilized for the placement of tying connections between the wall and the floors.

By employment of the method and means I above described, thev curtain wall may be erected rapidly and accurately with employment of slip forms operatedjin the customary;

fashion. 'The guides I 11, being made in standard lengths, may beemployed repeatedly-on different'jobs. Q 7
