.METHOD AND MEANS FOR CONSTRUCTING HOLLOW-CDNCRETE WALLS.
Application filed January 21, 1927. Serial releases.
This invention relates to structures of con :crete and like material which are adapted to be poured, or tamped into suitable forms which are removed, after the material has set, to be readjusted for continued use in the same or subsequent work. i r
The present invention contemplates means for forming hollow blocks and comprises core members and plate members, the spaces formed between the core and plate members, when properly set up, constituting the mold into which the concrete or other material is poured to form the block.
In accordance with the invention the plate member corresponding with the face of the block or structure is finished, or ornamented, to harmonize with the design of the block and is preferably arranged in horizontal position and a layer of the material is spread thereon and a reinforcement applied thereto. This plate thus prepared is placed in position and the mold space filled with the material forming the body of the block. The facing material, usually of sand and cement, spread upon the plate assures a close textured surface which could not be attained by filling the mold with the usual mixture of sand, gravel ,and cement and omitting the preparatory step of applying the facing material to the outer forming plate. i
While the drawings illustrate a preferred embodiment of the invention, it is to be understood that in adapting the means to meet specific needs and requirements the design may be varied and such other changes in the minor details of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof.
For a full understanding of the inven' tion and the merits thereof, reference is tobe had to the following description and the drawings hereto attached, in which,
Figure 1 is a perspective view of a form, or mold, embodying the invention, showing portions of a concrete structure resulting from the use thereof.
Figure 2 is an enlarged transverse sectional view on the line 22 of Figure 1. a
Figure 3 is a side View of two core members in the position which they occupy when placed between the plate members, the plate member on the near side being omitted.
Figure 4 is a detail perspective view of the facing plate member having a layer of facing material applied to a portion thereof and a metal reinforcement applied to the facing layer.
Corresponding and like parts are referred to in the following description and designated in theseveral views of the drawings by like reference characters.
The numeral 1 designates a hollow concrete structure and 2 is the space formed therein, the spaced walls being connected by ties 3. Thenumeral 4: designates'the facing which consists solely of sand and cement so as to present a close texture, free from spaces and airholes. The body of the structure consists of a mixture of sand, gravel and cement in determinate proportions.
The mold comprises core members for forming the spaces 2 and plate members cor responding to the inner and the outer walls ofthe structure. The mold may be of any determinate length and usually comprises sections of standard length to admit of adapting the form to varying lengths and courses in the formation of the structure. The numerals 5 and 6 designate the plate members comprising the mold or form and these members areof uniform length and width, and may consist of metal, wood, or other suitable material. The inner plate member 5 has its forming surface roughened, or finished in any preferred way, and as shown, a wire fabric 7 is applied thereto, the purpose being to give a rough surface to the inner face of the walls to insure a keying of the plaster or other finishmg coat applied thereto. The forming face of the outer plate member 6 may be ornamented or finished according to any de sign to be imparted to the outer surface of the wall or structure. The plate members 5 and 6, when properly set up, are spaced apart a distance corresponding to the thickness of the wall or block to'be constructed. Tie rods 8 connect the plate members 5 and 6. To prevent spreading of the plate members 5 and 6 and to insure correct positioning thereof metal strips 9 are provided and longitudinal edge portions arebent in opposite directions from the intermediate portion and atv a right angle thereto, as indicated at 10 and 11. The flanges 11 thus formed are secured to opposite sides of the wall by suitable means, such as rods 8 which replace the tie rods 8 previously molded therein; The flanges 10 extend along the outer side of the members 5 and 6 and are secured thereto by the tie rods 8 confining said members in position. In this manner alinement of the mold is as These reinforcing and confining strips 9 prevent any possible buckling or warping of the plate members.
The core members are disposed between the plate members 5 and 6 and each consists of similar side plates 12 of a Width equal to the width of the plate members 5 and 6 to admit of the upper and the lower edges of the several plates terminating in corresponding planes. End pieces 13 are disposed between the ends of the plates 12 and these end pieces taper throughout their length and are disposedwith their larger ends facing downwardly. The ends of the plates 12 are oppositely inclined and the core members are arranged to provide spaces between adjacent ends to correspond with the wedge shaped ties 3 forming connecting means between the walls of the structure bordering upon the space 2. Fillers l tareprovided to be inter-- posed between the plate members 5 and 6 and the core members to prevent inward movement of the plate members when the form or mold is set up preliminary to supplying of the material thereto. The several elements 13 and Mare clamped between the outer plate members and the core members. The end pieces 13 are of a length to project a short distance below the side plates 12 so as to-enter the space 2 of the block or wall previously formed. After the mold space'has been partly filled the spacing elements 14 are removed, it being remembered that the lateral pressure of thezmaterial is suilicientto retain the several parts in place. After the spacers ll'have been removed the mold is completely filled to the upper edges of the plates 5, 6 and 12.- After the material has set the nuts applied to the threaded ends of the tie rods 8 are removed, thereby admitting of removal of the plate members 5 and 6. The wedge elements 13 are driven downwardly a distance to release the'plates12 which are then .removed, after which the end pieces 13' are likewise 'WltlldlELWIl and the mold reassembled for a repetition of the operation.
Preliminary to assembling of the mold. the
, facing plate member 6 is arranged substan tially in horizontal'position and a layer of of the facing material is applied thereto, as indicated at 4, the same being spread by means of a trowel to the required thickness.
A wire fabrio15 is placed upon the. layer 4 of the facing material and is embedded therein and serves to retain such layer in place, and also constitutes areinforcement 'for strengthening the wall, block or like structure. The facing plate member thus prepared is placed in position to complete the mold or form, and-is held in place by means of the tie rods" 8 and properly spaced by means of the fillers 14. The material forming the body of the block or structure and usually consisting of sand, gravel and may be advantageously formed of concrete which is reinforced in. any suitable munncr and may, if desired, be faced with sheet metal. The wall is formed in courses, each course being permitted to set before removing the mold therefrom. The lower ends of the elements 1.3 are reduced slightly to facilitate their entrance and removal from the upper ends of the spaces 2. A plate 16 projects laterally from the lower end of each of the elements 13 and is equal in width thereto to come between the inner faces of the walls bordering upon the space These plates 16 come together and supportthe concrete forming the bond or t e 3. \Vhen the mold is placed upon the wall previously formed the plates 12 rest upon the wall adjacent the space 2 and the plates 5 and 6 rest upon the strips 9. See Figure 2 of the drawings. The mold is positioned so that the bonds or ties 3 will not interfere with the lower ends of the elements 13 and prevent their entrance into the space 2. The space between the plates 12 and the plates 5 and 6 is closed by the wall as shown most clearly in Figure 2.
The bond or tie forming space is closed at its bottom by the plates 16, as indicated most clearly in Figure 3 of the drawings.
Having thus described the invention, I
claim:
1. A mold for forming a hollow block or structure of concrete, the same comprising outer plate members, core members arranged between the plate members and having their adjacent ends spaced apart, ties connecting the outer plate members and fillers interposed between the plate members and core members.
2. A mold for forming concrete blocks. or structures, the same comprising outer plate members, metal strips having longitudinal edge portions bent to form flanges which extend in opposite directions, corresponding flanges engaging opposite sides of the block, or like structure. and the other flanges cngaging outer sides of the plate members, and tie rods connecting the plate members and engaging the flanges of the metal strips in contact with the outer sides thereof.
3. A .mold for forming a hollow block or structure of. concrete, the same comprising outer plate members, inner core members having adjacentends spaced apart and comprising side plates and wedge shaped end pieces, tapering spacers between the said plate members and the core members, and tie rods connecting the outer plate members and clamping the core members and spacers between the said outcr plate members.
In testimony whereof I afiix my signature.
