APPARATUS FOR BUILDING CONCRETE STRUCTURES.
Application filed April 2, 1912, Serial No. 688,069.
To all whom it'may concern." Be it known that I, CHAnLns Dm'rmons, a citizen of the United States, residing at Little Ferry, New Jersey, have invented certain new and useful Improvements in Apparatus for Building Concrete Structures, of which the following is a specification.
This invention relates to apparatus for building concrete structures and more particularly to apparatus for building walls such as the walls of houses. 7
One object of the invention is the provision of an apparatus which may be repeatedly handled in the building of concrete walls and the like and which forms when'in service a chamber or mold into which the concrete may be poured and allowed to set. A furtherobject of the invention is to provide an apparatus of the class described which is composed of'a minimum number of parts and is free from complicated joints and fastening so as to be readily and rapidly assembled and disassembled. 1
A further object of the invention is to provide an apparatus of the character described which is composed for the most part of stock materials, such as flat sheet metal, angle iron, etc., and requires few specially shaped parts,thereby materially reducing the cost of manufacture.
Further objects of the invention will appear in the following description, when read in connection with the accompanying drawings, and from the appended claims. In-the said drawings Thave illustrated a preferred embodiment of the invention but it is to be understood that the invention is not limited to the exact construction therein shown, but includes all such modifications thereof as properly fall'within the scope of the said claims. V
In the drawings: 1
Figure 1 is a perspective view of the apparatus employed in the construction of a corner of a hollow wall, 7
Figs. 2, 3, and 4 are detail views of portions of the apparatus which will be hereinafter described, and j Fig. 5 is a diagrammatic plan view show ing the relative arrangement of the'mold sections for a straight wall.
Referring now to the drawings in which like characters designate corresponding parts throughout the several views,"1 designates the plates forming the outer walls of the mold which plates preferably consist of Specification of Letters Fatent.
' crcte, the wedges 5 Patented Dec. *7, 1920.
Renewed December 1, 1919. Serial No. 341,720}.
flat metal sheets of suitable gage and may be of a length equal to the desired height of the'wall to be built. The plates '1 may be of any convenient'width and are arranged to conform to the pattern of the wall to be built withv their adjacent edges lapped as shown in Fig. 5. At suitable intervals vertically of the plates their lapped edges are provided with registering holes 2 through which the looped ends of the tie rods 3 project. These rods which may be formed of heavy wire, have their ends which are bent back to form the loops turned up at right angles to the loops to form stops to engage the inner faces of the plates, as shown at 4. The loops thus formed project through the plates a sufficient distance to receive a fastening wedge 5 which when driven in place,
tightly clamps the plates between the stops i and the wedges, thereby rigidly supporting and'maintaining the outer wall sections at a fixed distance apart throughout.
In order to prevent the mold sections bulging outward with the weight of the conare shaped to provide supports for angle iron braces 6 which extend horizontally around the mold as shown in Fig. 1. As hereshown the wedges areformed with shoulders 7 which rest on the loops of the rods 3 and with upward extensions 8' offset from their wedge portions a distance equal to the thickness of the angle irons. The ends of the angle iron braces 6 at the external corners of the mold are connected together by a suitable fastener for-instance as shown in Fig. 1, wherein a book 6 of heavy wire is swiveled in the end of one angle and engages over the flange of the other angle, the latter angle projecting beyond the end of the first mentioned' angle in the manner shown in the.
drawing. I
If it is desired to reinforce the wall the rods 3 may be bent to form seats for the reinforcing bars 9. This construction also serves the purpose of preventing the rods 3 being loosened when the mold sections are removed from the partially set concrete.
For the construction of hollow walls which are desirable 'forthe reason that the interior air space prevents moisture which may pass through the outer wall section from reaching the inner wall section, it is necessary to provide in the space between the outer and inner sides of the mold apair of spaced mold members which define the In the present apparatus the internal mold members consist of metal plates of a width slightly greater than half the Width of the plates forming the outer mold members so that they may be supported on the rods 3 with their adjacent edges slightly lapped as shown at '11 in Fig. 5. In order to maintain the inner mold members the proper dis tance apart and prevent their being displaced by the weight of the concrete, the plates 12, 12*, which form one side of the interior air space are bent at oneend to form lateral flanges 13', 13 respectively, 7
which extend across the air space and abut against the lapped edges of the plates 14, 14=,on the opposite side of the air space.
As stated above the inner mold plates are supported on the rods 3. In the present apparatus this is eflected by providing the plates 12 and 14 which lie to the right of V the adjacent rod 3 with upwardly inclined v the flanges 13, 13
notches in their left vertical edges, and providing . ther plates 12 and 14 with similar notches in their right vertical edges, so that the ing them to the right or left as the case may be. In order to prevent the edges of binding against the opposite plates pered as shown in Fig. 4, so that when once loosened the plates maybe easily lifted.
For forming a corner in a hollow wall,
-outer corner plates 15' and inner corner plates 16 are employed in addition to the apparatus described. The outer corner plates may be attached to the adjacent straight plates by the same means that 1s used for connecting the adjacent straight plates, but as the inner corner plates cannot be moved laterally in either direction on account otthe concrete in the molds, they are suspended from the adjacent inner-plates by means of hooks 17 attachedto their upper edges as shown in Fig. 1,-so that they may be withdrawn by a straight upward movement.
v The apparatus for forming hollow 'walls has been selected for illustration in the drawings but itwill of course be understood that for solid wallsit is merely necessary -to omit the inner mold members from the structure shown. t
In using the apparatus in'the construction of walls, the members are assembled in the wayshown in Figs. 1. and 5, in the desired configuration. The concrete isthen poured in and allowed to set sufficiently to retain its shape without support. The inner mold members are then removed by simply lifting them ofi the stay rods in the manner deplates'may be withdrawn by merely lift-' the flanges are slightly taand knocking the Wedges out of the loops in the ends on the stay'rods. The rods themselves are not removed butare cut off at the surface and left in place to reinforce the wall.
If it be desired to build a wall of greater height than convenient for a: single length of mold plates, the same plates used forthe lower section of the-wall may be set in place on top oi the lower section to form a mold for the next section andso on until the desired height is attained. When this is done the loops are left on the stay rods at the top of the. wall section and the lowest holes in the plates are slipped over these loops when the mold is assembled for thenext section.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is: c
, 1. In an apparatus of the class described, the combination of aiplurality of flat mold plates arranged to form two parallel walls, stay rods connecting said walls, said rods having loops projecting through said plates and shoulders engaging the inner faces of 7 said plates, wedges in saidloops for clamping said plates againstsaid shoulders, brace bars extending longitudinally of said wall, means formed on said wedges for maintaining said brace bars infixed relation to said plates, inner mold members and'means for supporting-said mold members between said external mold plates.
2. Inan apparatus for constructing hol-, low concrete walls, the combination of external mold plates, stay rods at different points vertically in each pair of-plates having means for maintaining said plates a fixed distance apart, inner moldplates arranged in parallel relation to said external plates and having inclined notches in their verticaledges engaging said stay rods and means formai'ntaining said innerqplates a fixed distance apart. c
