My invention relates to amold for erecting cast concrete structures, and more particularly to a sliding mold employed in the construction of silos, water towers and similar structures as well as of cast wall structures in general.
In the methods heretofore employed in the construction of the aforesaid structures, it has been customary, when using sliding lil frame molds, to raise the latter by means of iron bars, positioned inthe walls to be erected, said bars serving as racks cooperating with a. jack, mounted on the platform of the frame. These racks, which are of a greater height than the desired height of the structure, are, however, expensive, and remain upon completion of the work in the structurev and contribute as reinforcing members comparatively little to the strengthening of the walls.
The object of my present invention is to provide a simple, economical and efficient sliding frame withy mold plates attached thereto, which is supported by a variable 5 number of individual supporting elements in Fig. 2, showing the manner in which a` sliding frame element of the mold is supported and lifted, and
Fig. 2 is a horizontal section through the mold taken on the line 2-2 of Fig. 1.
In building a hollow, curved or straight l wall structure of large dimensions, a number of frames, depending upon theV size of the structure to be erected, are employed, the sliding plates of which are brought into alignment so as to constitute a mold of the desired form. Y
Referring to Fig. 1, the frame 1 with the sliding form walls 2 fixed thereto rests at the beginning on the foundation and the rack 4 lwhere the concretewalls 8 arealready comon the column 11, formed ofi individual blocks 6, which may be held in position by a tenon joint 12 or in any suitable manner known to those skilled in the art. The column 11 is'disposed within the tubular'guide 10 attached to frame y1, and rests likewise on f the foundation. Materialv is then poured` into the mold which, when the? firstf wall section 8 has sufficiently set, is raised by means of the aforementioned racks 11j by 'manipulating lifting devices 3, one being attached `toeach form supporting frame 1.f v Whilst ,this is being done, that portion of the sliding frameworkl is sulicient-ly supported by the neighbouring framework and lifting devices, one of which 'additionalframes 5 is shown in Fig. 2. As soon as a newfb'lockl has been brougntfinto position, the foot 5 `of the toothed rack 4L is brought down again upon it and an additional vblock is in correclimbing device. Y
The column 11 or-si-milar bodies serving as asupportfor the'hoisting device (3, 4) and consisting of the blocks 6 can be set up on a sponding manner.V placed under the next bottom part of the buildingstructure, forin- 'l stance on the foundations. Thev higher the wall 8,tlie` longer the' supporting column 11 will of course become. When the column-has reached a certain length, it will, depending places bend and lea-n against the walls of 4the Well 7, particularly since between the blocks and the wall of the well a free space'is vleft behind by the protecting'ftube 10, as shown 'near the bottom-ofthe well in Figyl.v The leaning of the supporting'column will always take place only below the protecting tube 10,
pletelyset. Y
lupon the shape of the'column blocks,at.some
Y 90' According to my invention it is of course l also possible to place,.instead of the blocks 6, other supporting members or bodies under l the lifting device. It is in all cases essential that the supporting members or bodies should l.
rest onparts of the building structure which` are already solid.
A further advantageof the `new lifting arrangement consists in the possibility of using particularly simple lifting devices with shortr:A
lifting bars or rods (toothed racks 4, spindles or the like). The Column blocks may consist of any'suitable material, for instance wood; concrete blocks maypalsoA be employed,
Whichwhen feasible may be formed right at the building site.
The blocks may also be provided7 for EX; ample, with mortise and tenon and; jonedm. p
together so that they maybe taken out when the building is finished, and used again.
While I have shown my invention in its preferred form, it will loe-obvious to those skilled in the art that it is susceptible of minor changes'and modifications, without departing from thespirit thereof, and I desire, therefore, that only such vlimitations lshall be placed thereupon `as are imposed by .the prior art,
.I claim 'as my invention:
l. In a mold for casting building structures,- a frame having form plates attached toit at opposite sides, a supporting column for said frame, composed of a variable number of individual supporting members, said column being positioned midway between two opposing form plates and resting on the 'foundation for the building structure, and .means disposed on said supporting column forraising said frame,and a hollow guide, attached to said frame and containing a substantial portion of the upper part ofpsaid e column, for laterally supportingl said column through the structure portion in vthe course of casting and setting.
2. In a mo-ld for casting building structures, a frame having form plates attached toit at opposite sides, a supporting column 4for said frame, composed of a variable number of individual supporting members, said column being positioned midway between two opposing form plates and resting on the foundation for the buildingstructure, and
iineans disposed on said supporting column t for raising said. frame, and a hollow guide,
attached to said frame and containing a subf stantial portion of the upper part of Ysaid column, for laterally 'supporting said column through the structure portion in the course of casting and setting, said guide having an aperture at its upper end for inserting additional column members to increase the height of thevcolumn. f Y Y In testimony whereof I affix my signature.
