Application August 12, 1953, Serial No. 373,801
7 Claims. (Cl. 25131) This invention relates to monolithic types of building construction and particularly to metal door and window frame bucks.
With the present construction, particularly around the doors and windows, it is possible by a single pouring of concrete from a single selected location, to completely fill the conventional forms whereby both the exterior walls and the partition walls are established. Upon the completion of the walls it is then only necessary to install the door and window frames in position.
It is an object of my invention to adequately prepare the door and window openings for subsequent pouring of the concrete.
Another object is to provide for the easy installation and removal of the subject bucks.
A further object is to facilitate the placement and straightening of the wire mesh reinforcing element used in the construction of the walls.
Still another object is to establish uniformity in the relative positioning of the wire mesh re-inforcing element.
An additional object is to maintain the door and window bucks in rigid and secure position within the wall structure.
A still further object is to maintain the walls of the bucks in space relationship.
A still additional object is to permit the end walls of the buck to be released to enable the easy removal of the bucks from the door and window openings.
Further objects and advantages of the invention will be apparent from the drawing and specification.
In the drawings,
Figure l is a front elevation of a door buck in position in a partition wall with the front form board removed.
Figure 2 is a vertical section taken on the line 2 of Figure 1.
Figure 3 is another vertical section taken on the line 33 of Figure 1.
Figure 4 is a horizontal section taken on the line 4-4 of Figure 1.
Figure 5 is a fragmentary elevation of the top of the door buck.
Figure 6 is a front elevation of a window buck in position with the front form board removed.
Figure 7 is vertical section taken on the line 7-7 of Figure 6, while Figures 8 and 9 are modifications of the attaching means for the end walls and members to the top plate.
Referring particularly to the door buck shown in Figures l to 5, inclusive, the numeral it) indicates the buck generally, having side walls 12 and 14, a top plate 16 and a bottom 18. Two spaced partitions 20 and 22, vertically positioned, are secured by welding to the top and bottom plates as shown at 23.
Two central strengthening plates 2 are pivotally secured to the end or side walls at 26. Vthen swung up to a horizontal position, the ends are adapted to be held secured by conventional spring latches 28. Additional strengthening brace members 30 are pivotally attached to the end walls at 32 for a purpose to be later described.
It is to be noticed that the side walls 12 and 14 are pivotally secured to the top wall plate 16 but merely abut the bottom plate 18. The strengthening brace members 30, when in position and secured to the pivot, as shown at 32, slant downwardly and inwardly at an angle so that the curved end or hook 33 is adapted to be forced into an opening 40 in each of the partition walls 20 and 22, adjacent the top and bottom. When the hooks 38, having an aperture 41, are inserted into the openings 49, wedge members 42 are forced into each of these openings 41 to secure the strengthening members 319 in position against the partition walls.
Although only two of the turnbuckles 44 are shown in Figures 1 and 3, the central area 48 between the spaced partition walls is arrangel to accommodate a plurality of the adjusting members having elongated threaded shafts 46 and loops or eyes Sll. These threaded shafts 46 are adapted to be inserted into the apertures 52 in the partition walls and through apertures 36, having loops or eyes St) on the outer ends of the shafts. It is to be noticed that the apertures in the end walls, strengthening members and partition wall are in alignment.
It can be appreciated that when the wire mesh re-inforcing members 58 are installed between the plywood form board dd as particularly shown in Figures 1 and 4, they are customarily not straight but rather twisted and out of shape and so defeat the purpose for which they were intended. It is desired that these mesh members 58 be approximately parallel to the plywood sides and centrally thereof to tie in the cement when poured and hardened.
Apertured flanges 62 are secured in any well known manner to the underside of the top plate 16 and the upper surface of the bottom plate 18. Bolts or screws 64 may be used to secure the buck to the front and rear plywood form boards to maintain the buck in position.
In installation, after the plywood forms have been arranged with the wire mesh located vertically between the plywood, the exterior and interior wall bucks are then positioned within the openings provided and then secured to the rear plywood form by the attaching means shown at 62 with the bottom edge is resting on the floor. In the form shown in Figure l the end walls 12 and 14 are forced outward to form an (approximate) rectangle with the top and bottom plate members 16 and 18.
The pivotal mounted strengthening brace members 36 are then forced inwardly until the hooks 3 3, of reduced thickness, are positioned in the apertures 46 and the wedges 42 inserted in the end apertures 4ft to secure the end and partition walls in relative positions. The pivotal mounted central plates 24 are then brought up into approximate horizontal positions and forced into engagement with the spring latches 2d.
The buck is then in position so that the turnbuckles 44 may be tightened to draw the wire mesh 53 inwardly to compensate for any existing slack. Obviously, tightening or adjustment of the turnbuckles 44 will compensate for looseness of the wire mesh in which ever side it occurs. When the mesh on both sides of the buck is taut and in the desired parallel relationship with the plywood sides, the forms are then ready for the pouring of the cement. As a precaution, a plywood facing may be installed flush with the inside face of the buck.
When the cement has hardened, the bucks can be easily removed from the forms without danger of chipping or marring the cement around the opening. First, the plate members 36 are releasedfrom their engagement with the partition walls 20 and 22. After the central plate members 24 are released from the latches 28, all of these plates may be forced backward against the end walls 12 and 14. Then the end walls may be loosened from the concrete sides by any suitable tool after the bail wires 58 have all been individually cut at points immediately adjacent the inner surfaces of the end walls. In that these bale wires have been separated from the opposite ends, now embedded in the hardened cement, the inward or pivotal movement of these end walls at their bottoms will not be effected by the plurality of bale wires running through the openings therein. The relative positions of the end walls, strengthening members 36, as well as the central plate members 24, are generally indicated in dotted lines in Figure 1. When the above has been accomplished, the buck may then be readily removed from the opening, leaving a smooth surface at the top, bottom and sides of the doorway opening.
With particular reference to the window bucks shown in Figures 6 and 7, the numeral 66 indicates the window buck generally, having similar end walls 68, top plate 70 and bottom plate 72. Spaced partitions 74 are located centrally of the buck and are welded to the top and bottom plates of the door bucks as indicated at 76. Diagonally positioned strengthening members 78 may also be pivoted to the top plate 70 similarly to the construction shown in the window buck or may be welded as shown at 80. If pivoted the inturned hooks 82 may be secured in a similar manner as at 84, to the short partition walls. A comparable horizontal central plate 86 may be pivotally mounted to the end walls as at 88 with a similar latching means 90 on the outer surfaces of the partition walls.
Besides being of a shorter height than the door bucks, these window bucks are provided with an angularly disposed bottom plate 72 so as to form the conventional slanting window sill when the concrete wall at that location has been formed. As in the door buck, apertures 92 are formed six inches on center in the end walls; apertures 94 in the strengthening brace members, and apertures 96 in the partition walls.
Similar turnbuckles 98 having threaded shafts 1M and end loops 102 are shown installed. These in turn are similarly connected to bail wires 104 which are secured by hooks 106 and welding to the wire mesh re-inforcing members 108.
When the cement is poured it will work around and under the window buck out then up the sides. It is to be noticed that the window bucks are set originally so that the top of the buck is flush with the wall form after the cement has hardened, the window buck is similarly re moved from the window opening, the top of the window buck being flush with the plywood forms all open space is crossed for the subsequent installation of the conventional window frame construction.
In Figures 8 and 9, an alternative arrangement for pivotally mounting both the end walls and slanting strengthening braces is shown. A top plate 110 is shown having a downwardly extending flange or apron 112. A flange 114 is bolted to the top plate in both top corners having a shaft 116 extending longitudinally across the depth of the buck 118 and mounted in bearings in the flange 114. The end walls 120 are provided with two right angular flanges 122 at the top which are provided with enlarged top portions 121 and drilled to be mounted on the shaft 116 A similar enlarged portion 124-is formed on the end of the strengthening braces 126 to be also mounted on the shaft 116'.
this construction, the braces may beeasily rotated into position for clamping against the partition walls. In that these members are spaced on the shaft 116 and the end walls are flush with the edge of the flange 112 with the supporting pivotal constru ction set in from the sides, the members may both be easily rotated about the shaft without interference.
While preferred forms of this invention are illustrated, it will be appreciated that modifications that fall within the scope of the appended claims are intended to be included herein.
