Mount Kisco, N.Y. 10549 Substitute for abandoned application Ser. No. 856,493,
Dec. 1, 1959. This application Nov. 16, 1966, Ser. No.
' 3 Claims. (Cl. 249-40) This invention relates to metal forms for concrete.
This application is a substitute application to take the place of application Ser. No. 856,493, filed Dec. 1, 1959 and allowed Sept. 11, 1961, and abandoned because of failure to pay the final fee.
Various types and designs of metal concrete forms have been developed but in general they are complicated and expensive and cannot be easily and quickly assembled.
This invention has for its salient object to provide metal forms for concrete that are simple, practical and inexpensive in construction.
Another object of the invention is to provide metal forms of the character described that can be easily and quickly assembled and will efliciently perform the function for which they are desired.
Further objects of the invention will appear from the following specification taken in connection with the drawings which form a part of this application, and in which:
FIG. 1 is a vertical, sectional elevation of metal forms assembled and held in position to retain concrete;
FIG. 2 is a perspective elevational view of one of the metal plates;
FIG. 3 is a perspective exploded view showing the various parts which are used at the base of the form to position and hold the metal plates which, when assembled, constitute the concrete form;
FIG. 4 is a fragmentary, sectional elevation showing portions of two of the plates in separated position before assembly and a portion of a tie rod which is used to space and hold in position the opposing plates between which the concrete is poured;
FIG. 5 is a view similar to FIG. 4 but showing the two plates and tie rod in assembled position;
FIG. 6 is a horizontal, sectional elevation taken substantially on line 6-6 of FIG. 1, looking in the direction of the arrows; and
FIG. 7 is a horizontal, sectional elevation taken substantially on line 77 of FIG. 1, looking in the direction of the arrows.
In the particular embodiment of the invention illustrated in the drawings, the metal forms are used on a concrete base 10 to form a support for retaining concrete. A base bar 11 having a central hole 12 is placed on the base 10, which has an upwardly extending stud 13 which projects through the hole 12, the stud 13 being shown in FIG. 3 as extending through the hole 12. The bar 11 has upwardly extending therefrom, studs 14, 15 and 16. U-shaped members and 21 are placed on the studs 14 and 15.
The concrete forms are formed by a plurality of superposed longitudinal plates 25 which have flanges 26 at the bottoms thereof and flanges 27 at the tops thereof, the flanges 27 having vertical flanges 28 at the upper ends thereof forming L-shaped extensions at the upper ends of the plates 25.
As shown in FIG. 1, the bottom plates 25, 25 are mounted with the flanges 26 extending outwardly, the flanges of the opposing plates extending in opposite directions and resting on the upper surfaces of the lower portions of the U-shaped members 20 and 21. A spacer bar 30 having flanges 31 and 32 at the ends thereof has a central hole 33 which receives the stud 13 and the bar 30 is mounted on the upper surface of the bar 11 and the end flanges 31 and 32 rest against the inner surfaces of the plates 25, 25. Thereafter, the U-shaped members 20 and 21 are placed on the studs 14 and 15 which extend through holes 34 in the respective members 20 and 21. When so positioned, the upper-portions engage at their ends the outer surface of the plates 25, 25, thus holding the plates between the flanges 31 and 32 and the end of the upper strap portions of the U-shaped members 20 and 21.
Initial installation of the form comprises placing bar 11 on the base 10 with the stud 13 extending upwardly through the hole 12 and the bar 11 having at opposite ends thereof studs 14, 15 and 16, as clearly shown in FIG. 3. The U-shaped members 20 and 21 are set on the studs 14 and 15. The flanges 26 on the upright plates 25 are placed in the channel of members 20 and 21 and thereafter the bar 30 is mounted on the stud 13 and the flanges 31 and 32 at the ends thereof engage the inner walls of the plates 25. The outer walls are engaged by the upper portions of the channels 20 and 21.
After the lower plates 25, 25 have been so assembled, the next upper plates 25a, 250 are assembled on the plates 25, 25 in the manner shown particularly in FIGS. 4 and 5. From these figures it will seen that the lower flanges 26 of the plates 25a, 2511 are disposed above the flanges 27 of the plates 25, 25. The flanges 27 have vertical openings 35 which receive downwardly extending ends 36 of tie rods 37 which extend between the opposing plates 25, 25 and hold these plates in spaced relation. The tie rods have their ends 36 inserted through the openings 35 and thereafter the next upper plate 25a is moved downwardly so that the flange 26 thereof will rest on the flange 27 of the plate 25. In order to accommodate the tie rod, a
recess 38 is formed at the junction of the flange 26 and the vertical Wall of the plate 25. The plates are shown in FIG. 5 as assembled one on top of the other with the tie rod in position. It will be understood that FIGS. 4 and 5 show the tie rod connection at one side of the form and that the connection at the other side is exactly the same.
After the plates 25 and 25a have been assembled in the manner described and are positioned as shown in FIG. 1, the assembled plates are held in position by hooks 40 which are pivoted on a vertical support 41 which is mounted on the stud 16 on the bar 11. The supports 41 may be constructed and mounted in any desired manner and are held in channels 45 carried by or formed on U-shaped brackets 46 which are secured to horizontal members 47 which are suitably supported and may, if desired, be formed by the upper bar, such as a 2 x 4 of a saw horse.
As shown in FIG. 7, the members 47 and vertical supports 41 and brackets 46 may be provided and mounted in spaced relation along the plates 25, suflicient supports being provided to firmly hold the walls formed by the vertical plates 25 in firm position. Obviously, the members 47 may be so mounted that they can be moved longitudinally to properly position the vertical supports 41 and hold the walls of the concrete form in vertical position. The lengths of the vertical supports 41 can be extended, if desired, and in FIG. 1 a second length 41a extends beyond the length of support 41 and is embraced by the bracket 46.
From the foregoing description it will be clear that the metal forms can be easily and quickly assembled and will be firmly held in spaced relation and in rigid position when the concrete is poured into the space between the forms. Moreover, after the concrete has set, the forms can be readily disassembled and removed for future use. The metal forms, when disassembled, will take up a minimum amount of storage space.
Although one specific embodiment of the invention has been particularly shown and described it Will be understood that the invention is capable of modification and that changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention, as expressed in the following claims.
What I claim is:
