Claims. 1

This invention relates to the construction of building walls with forms of the progressive type wherein a form positioned on a wall is removed and installed in a superimposed position as concrete sets to form a portion of a wall, and in particular this invention relates to pairs oi forms with one pair positioned upon a lower pair with the sides of the pairs tied together by Wires eX- tended therethrough, and in which simulated mortar joints may oe formed in the face of a wall by projections on the inner surfaces of the outer sections oT" the forms.

The purpose of this invention is to provide a progressive type of form for the construction of building walls wherein forms used to cast the lower part of a wall are removed and reused to cast upper parts thereof, and wherein the lower edges of the removed forms which are repositioned to form upper parts of the wall are adjustable to eliminate lines or offsets where adjoining edges of the forms meet.

In the usual type of progressive form for concrete walls in building construction the entire form is moved upwardly and repositioned on the upper edge or" the set concrete and where forms of this type are used it is difficult to line up the inner surfaces to provide smooth and uninterrupted Wall surfaces. With this thought in mind this invention contemplates an improved type of progressive form wherein one section remains in i l,

position on a wall while a lower set is removed and installed above the set remaining on the wall and with this type of construction it is possible to provide adjusting means between the upper edge of the form remaining on the wall and the superimposed form whereby the inner surfaces may be adjusted until the meeting edges are in common planes.

The object of this invention, is therefore, to provide means for constructing a building wall form of the progressive type whereby lower sections are removable and installed upon upper sections and the inner faces of the upper sections are adjustable in relation to the inner faces of the lower sections.

Another object of the invention is to provide a building wall form of the progressive type in which simulated mortar joints may be provided in the outer face of a wall formed thereby.

A further object of the invention is to provide a building wall form of the progressive type in which means is provided for keeping the thickness of the wall constant.

A further object oi the invention is to provide progressive building wall forms having upper and lower pairs of sections and in which one section is superimposed upon another with the former section in position on a wall, which provides a form of a simple and economical construction.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings wherein:

The plates |58 may be positioned between ribs |63 similar to the ribs 2| and these plates are secured over panels |5| similar to the panels Ill and With the parts arranged in this manner the building walls are constructed by setting a pair of forms on a foundation, as indicated by the numeral |62 with the spacers 2|] between the upper edges and with the forms secured together by the tie wires 39 concrete is poured in the form to a point |62 corresponding with the lower edges of the spacers 2li.. After a predetermined period of time, when the concrete is set the spacers 2G are removed and a pair of similar forms are positioned upon the forms |3 and with the adjusting screws I1 extended through the tongues 36 and into the sockets I6. The upper edges are held by the spacers 23 and the forms are held together by the tie wires 39. With the upper form in position the lower edges of the sides thereof are adjusted by the screws |1 until the inner surfaces of the liners le and I5 are flush with the corresponding surfaces of the liners of the form below. After the concrete in the lower pair of forms is set sufliciently to take the weight of a corresponding layer above concrete is poured between the upper forms, also to a point spaced from the upper edges and substantially corresponding with the lower edges of the spacers 20.

When the concrete in the lower pair of forms has set for a predetermined period of time, such as 48 hours, the lower forms are removed and positioned upon the upper edges of the upper pair of forms and the cycle of operations is continued.

The spacers 2li govern the width of the wall so that the width remains constant throughout the height thereof and the adjusting screws 44 clamp the sections of the forms against the shoulders of the spacers with the adjusting screws Il adjusting the lower edges thereof.

A plurality of veneer plates HBS as illustrated in Figures 2l and 22 may be used in combination with the forni to provide a wall facing `to imitate brick, stone or the like.

In the design shown these plates are Provided with inwardly inclined flanges lee which are embedded in the concrete wall to permanently retain the plates in position on the face of the wall.

The veneer plates 1F53 are inserted in the spaces between the rios 2i on the liners or plates iii whereby they are frictionally secured in position during the construction of the wall, and with the flanges E64 embedded in the material of the wall these plates will remain in position as the forms are removed.

By this means concrete walls may be faced with veneer panels or plates and the plates may be colored and shaped to represent brick, stone, wood, or other materials.

It will be understood that other modifications may be made in the design and arrangement oi the parts without departing from the spirit of the invention.
