The invention consists in, the. novel construction, arrangement and. combinations of parts hereinafter morev particularly described and claimed.
In. the drawings Flame 1. is. a. view in perspective f he top at a foundation showing bolts embedded therein for receiving the perforated ends of ribbed transverse bars.
Figure 2 is a view in. perspective or a section Of a foundation showing transversely disposed bars and vertical form board-retaining bars held in the foundation by bolts embedded in said foundation and. disclosing the second stage in. the erection of the mold.
Figure 3 is a. view in perspective of the section of the foundation shown in Figure 2 with form boards held in place. by the transverse bars and vertical bars and disclosing the third stage in the erection of'the. mold.-
Figure 4, i a view in perspective of, the section f he; foundation shown. in Figures. 1 to 3 inelusive;- discl'osing the additi n. of; transv rse bars t th upper ed es. of the form. boards for retaining the boards in place while the plastic materials are being poured.
Figure 5, is a view in perspective of a section of a foundation with set spaced walls risin therefrom showing the last stage in the formation of; a first course and disclosing the inner form boards in the process of removal, and
Figure. 6 is a view in perspective of the completed first course shown in Figure 5 and disclosing additional transverse bars and vertical bars secured to top flanges of the vertical bars employed in the: first course for holding elevated form boards to provide a mold for a succeeding course; of plastic materials.
Referring more particularly to Figure 1, l0 designates the usual foundation of plastic mas. terials which are set in a channel. or trench dug in. the ground. Pairs of bolts H are placed in the foundation before the plastic materials have set. The distance between each pair of bolts transversely of the foundation is determined by passages inv the. ends of transverse bars l2, while the, distance between the pairs of bolts lengthwise of the foundation is determined by the length of form boards l3 and I4,
Each transverse, bar l2 has an upstanding short rib 55 adjacent each end of sad bar, a centrally disposed rib l6 and a pair of ribs ll atv each side cf the rib id. The number and spacing of the ribs will depend upon the number and the positions of form, boards required for building a particular type or wall.
A vertical bar or form board support 20 has a lateral flange 2| at the lower end and said flange is provided with a perforation to receive one of the bolts 5! A nut 2.2 secures said flange to an end. of a. transverse, bar 12. so that the bars 20 will he held, in. vertical positions. The perforations in the flanges 2i are so placed that. the inner faces of the bars 20 will be spaced a sufficient distance from the outer ribs I5 that the. lower 3 edges of the form boards I3 will be received neatly between the ribs I5 and the bars 20. The upper end of each vertical bar has a lateral flange 23 provided with a perforation 24 for a purpose which will be presentedly explained.
The inner form boards I4 have the lower edges received between the central rib I6 and an adjacent rib I'I so that the inner boards I4 will provide an air space between the set vertical walls 25 and 26 (Figures 5 and 6) After the form boards are placed in position as shown in Figure 3 upper transverse bars 30 are placed on the tops of said boards with perforations in the ends of said bars aligning with the perforations 24 in the upper flanges 23 at the tops of the vertical bars 20. The bars 30 are then secured to the flanges 23 by bolts 3| and nuts 32 (Figure 4) A rib 33 is located on the upper surface of the bar 30 adjacent each end thereof and pairs of ribs 34 and 35 are disposed between the end ribs 33. The lower edge of an outer form board (not shown) is adapted to be received between an outer' rib 33 and an elevated vertical bar 36 secured by the bolts 3| to the ends of the transverse bars 30 (Figure 6). The pairs of ribs 34 and 35 are adapted to receive the lower edges of a pair of inner form boards (not shown).
The under face of each transverse bar, adjacent each end, has a depending rib 43 which bears against the inner upper faces of the form boards I3. The under face of each transverse bar 33 has also pairs of depending ribs 4| which receive the upper edges of the inner form boards I i (Figure 4).
The form boards I3 and M are cut the proper size from plywood composed of three layers. These form boards are treated with an oil to render them impervious to moisture so that they will not contract or expand in use or in storage after having been subjected to the wet plastics.
In erecting walls with the molds of knock-down construction, the foundation I0 is laid first and the pairs of bolts II are forced into the wet plastic. The transverse bars I2 are applied with the perforations in the ends of said bars receiving said bolts. The vertical form supporting bars are positioned as shown in Figure 2 and the nuts 22 are screwed up tight on the flanges 2| after the cement has set.
The inner form boards I4 are placed upon the transverse bars I2 with the lower edges seated on the transverse bars on opposite sides of the centrally disposed rib I6. The outer form boards I3 are next positioned with the lower edges seated between the end ribs I5 and the vertical bars 20, the outer faces of the form boards being in contact with the inner faces of said vertical bars as shown in Figure 3.
Figure 4 discloses the application of the top transverse bars 30 to the upper flanges 23 of the vertical bars 20 where bolts 3! and nuts 32 secure the transverse bars to said flanges. When the transverse bars 33 are laid upon the flanges 23, the pairs of dependin ribs 4| are fitted over the upper edges of the form boards I4 while the end ribs engage the inner faces of the upper ends of the form boards I 3 forcing the boards in contact with the vertical bars 20.
The plastic materials are ready to be poured into the spaces between the pairs of form boards l3 and I4. When the materials have set, the upper transverse bars 30 are removed after which the inner form boards I3 are withdrawn (Figure5).
The next course can only be applied after the transverse bars are returned and the succeeding uprights or form supporting bars 36 are secured in place by the bolts 3| and nuts 32. The removed form boards I4 are then seated in the pins of upstanding ribs 34 and 35 while a pair of additional outer form boards are so placed that the lower edges thereof will be seated between the upstanding end ribs 33 and the adjacently disposed vertical bars 35. A third group of transverse bars are secured to the upper end of the vertical bars 36 with corresponding depending ribs to engage and hold the upper ends of the form boards in place.
Since all of the additional transverse bars and vertical bars required to raise the walls to the proper height are identical with the transverse bars 30 and the vertical bars 20 no further disclosure need be set forth. However, when the extreme height of the wall has been reached transverse bars which are identical with those shown at I2 in Figure 1 and Figure 2 are employed although said bars are reversed so that the fins or ribs will be in pending positions while the upper surfaces will be flat.
When the walls have been completed the vertical bars 20 and 36 together with any succeeding bars will be removed as will be all the outer mold boards I3 which have been returned in place during the progressive building stages of the walls.
When pairs of spaced walls 25 and 23 are formed as shown in Figures 5 and 6, all the transverse bars will remain embedded in the set plastic materials and will act as the rods between said walls. 011 the other hand, when single walls are constructed the inner form boards will be eliminated as will be the upstanding and depending ribs which are required for positioning said inner form boards.
The projecting ends of the transverse bars may be readily broken off since the transverse bars are made of cast iron.
