Flg. 8 is a view of similar character to Fig. 5 showing a number of locking members having been reversed and reattached tothe means which is embedded within the wall for a purpose hereinafter specified,
F 1g. 9 is a fragmentary sectional elevation of the wall including means which are embedded therein in accordance with my in: ventlon and showing the same with the above mentioned members removed,
- Fig. 10 IS a perspect ve view showing one of my improved locking members together with a portion of one of the members which is adapted to beembedded in the wall and illustrating how said members are connected together, and
Figs. 11 and 12 are fragmentary sectional elevations showing two modifications of my lnvention.
Referring to Figs. 1 to 10 inclusive of the drawings, my invention includes a mold comprising two series 13 and '14 of mold sections 15. The mold sections of each series, as shown in Fig. 3, are adapted to be positioned one above the other so as to provide a space 16 in which concrete or other building material can be poured. The tops of the sections 15 have longitudinally extending channels or grooves 17 and the bottoms of the uppermost sections 15 have longitudinally extending ribs 18 which are adapted to extend into the channels 17 as will hereinafter he more fully described.
In building a wall the bottom mold sections are spaced apart as illustrated in Figs. 1 and 2 and this spacing is effected by means of spacers or separators 19 which are connected at opposite ends to locking members 20 and 21. Thespacers or separators 19 are made up of heavy wire or bar metal and at their opposite ends arebent to provide loops 22. The free ends 23 areybent at an angle to the length of the separators.
The locking members 20 and 21 may be made of any suitable material, such as sheet metal, and include substantially flat portions 24 and straight flanges 25 which are bent substantially at right angles to the flat portions 24. The flat portions 24 are ada ted to rest upon the upper surface 26' of t e mold sections and the flanges 25 are adapted to be positioned within the channels 17 adjacent one side thereof. Each of the locking members includes a curved end 27 and a notch 27 which extends inwardly at a slant to two edges 28 and 29; said edges 28 and 29 being substantially at right angles to each other and the edge 28 is substantially at right angles to the length of the flange 25. By this arrangement a tongue or hook 30 is produced which projects beyond the plane of the edge 28 on each of the locking members and these tongues can be slipped through the looped portions 22 of the separators 19 so that said looped portions 22 will enter the notches 27. 2
By having the flat portions 24 ot the looking members 20 and 21 resting upon the upper surface 26, the looped portions 22 will directly engage the outer side surfaces 31 of the mold sections and the ends 23 will de: pend into the space 16 between the mold sections, as clearly shown in Fig. 1. The distance between the flange 25 and the innermost portion of the notch 27 of each of the locking members is such that when the separator 19 is in the position shown in Fig. 1 that the flanges 25 of the locking members will snugly fit against the sides of the channels 17.
After the lowermost sections of the mold have been positioned as just described with the separators and locks in position and spaced apart within the length of the mold sections, as shown in Fig. 2, the upper mold. sections can be applied so that the ribs 18 of the upper mold sections. extend into the channels 1? ot the lower sections and thus the locking members are firmly held between the lower and upper mold sections of each series. Other locking members and separators can then be applied to the upper s.ec tions and thus the series of mold sections can be built up with the separators l9 serving to space and hold together the two series of mold sections. It will be noted that the mold sections can be made oi wood or other suitable material and can. be made of any desired length. Also the separators with their locking members can be positioned at any desired distances apart according to the nature of the hook. In addition, the separators 19 can be made of variouslengths tosuit walls of various thicknesses.
litter the mold sections have been arranged as above described, concrete or other building material can be poured in the space 16 between the series of mold sections and permitted to set, such for example as illustrated inFig. 8.
By arranging the channels and ribs as above described, lateral interlock is provided between the mold sections of each series and furthermore this arrangement permits the concrete from running out through the partin'gs between the mold sections. Any desired number of superimposed sec tions can'be built up and after the concrete has set, the lowermost mold sections can be removed as shown in Fig. i and it will be noted that the locking members 20 and 21 will serve as shelves for supporting the upper mold sections. After the lowermost sections have been removed. it will be noted that spaces 32 are present due to the construction of the locking members 20 and 21, and these spaces permit a lever or pry to be inserted between the ribs of the upper mold sections and the wall so as to facilitate the removal of said upper sections.
After the mold sections have been released, it will be noted that the locking members 20 and 21 are still attached to the looped portions 22 of the separators 19 within the wall 33 and desired these locking members can be permitted to remain attached to the wall where they will serve as shelves or supports for securing iurring or other material to the wall; thereby leaving air space to prevent dampness vfrom going through the wall to the inside of the. building. If it desired to remove these locking members they can be readily removed by bearing upwardly thereon so as to slightly loosen them and afterward swinging them as shown in Figs. 6 and 7 so that they can be easilydetached. If desired, these locking members can be inverted and reapplied to the looped portions 22 ot the separators with the flanges. 25 extending upwardly as shown in Fig. 8 and as such they. may be used for supporting or attaching material of any kind to the wall.
It will be notedthat the members 19 in addition to forming separators for the mold sections in the process of the building of the wall, serve as reinforcing means for the concrete, as clearly shown in Fig. 9, and thereby tend to greatly strengthen the wall. The end portions 23, by being bent as above described, form anchoring means for the members 19 within the wall and if desired the looped portions 22 can be used for attaclr ment of devices; of any character. and thus are of a great advantage since ordinarily it is difficult to attach devices to a, concrete wall and by the use of my invention this can be done without the inclusion of any additional expansion bolts or other means usually employed where it is desired to attach devices to a wall of this character.
In the form of my invention shown in Fig.
11, I have shown practically the same construction with the exception that instead of providing the mold sections with the channels and ribs as above described, each of the mold sections 15 has a slot 34 into which the flange of the adjacent locking member extends and the upper portion of each mold section has an extension 85 which fits ina recess 36 in the lowermost portion of the upper section. This provides a lap oint, such as shown at 37, which serves to prevent the concrete flowing directly through the parting between the mold sections. In all other respects the construction of the parts is similar to that described in connection with Figs. 1 to 10 inclusive and I havetherefore given corresponding parts similar reference numerals.
In the formof my invention shown in Fig. 12, the mold sections l5 are cut away at their upper and outer portions and an angle 38 is inserted which forms a support at the top for the locking members between the sections. Plates 39 are secured to the outer surfaces of the mold sectionsand filling pieces 40 serve to space the plates 39 from the leg portions 41 of the angles 88. The lower parts of the mold sections 15 have strips 42 which extend downwardly between the plates 39 and leg portions 41 of the an gles 38. The flanges 25 of the locking members are adapted to fit between the strips 42 and the leg portions 41 of the angles 38. In this manner the strips 42 depend in such manner as to prevent the concrete from working its way out between the sections.
In the foregoing description and in the accompanying claims I have used the term wall, however, it will be understood that wherever this term is employed it is meant to imply a wall, floor, partition or similar structure.
lVhile I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.
