JOINT CONSTRUCTION FOR CONCRETE STRUCTURES The present invention relates to a joint between preformed wall panels and floor slabs and, more particularly, to such an arrangement for forming an attractive and strong joint between such panels and slabs.

It is the primary object of the present invention to provide an improved joint between preformed wall panels and preformed floor slabs.

It is also an object of the invention to provide a joint between preformed wall panels and floor slabs which presents an attractive appearance.

It is a further object of the invention to provide such a joint which is capable of compensating for minor variations in wall heighth without detracting from the appearance of or weakening the finished joint.

As will become apparent in the following detailed description, the above and other objects of the invention are achieved by providing a joint construction for preformed wall panels and floor slabs which utilizes a molding of, for example, extruded vinyl, secured along the upper edge of the wall slab and contacting the lower surface of the floor panel, shim means for maintaining spacing between the top surface of the wall panels and the bottom surface of the floor slabs, and stopper plates positioned within the voids of the wall panels to'limit the depth of concrete penetration into the panels, the joint being completed by the addition of fresh concrete to the upper surface of the floor slabs to form the finished floor with the concrete penetrating into the upper portion of the wall panel voids andthe space between the top edge of the wall panels and the floor slabs to fill the inner surfaces of the moldings.

For a more complete understanding of the invention and the objects and advantages thereof reference should be had to the following detailed description and the accompanying drawings. wherein there is shown a preferred embodiment of the invention.

In the drawing:

FIG. 1 is a plan view of a floor and wall panel joint formed according tothe present invention, with portions of the structure broken away for clarity;

FIGS. 2 and 3 are fragmentary vertical sections taken along the lines 2-2 and 33, respectively, of FIG. 1;

FIG. 4 is a fragmentary vertical section through a completed joint; and

FIG. 5 is a perspective view of the molding used in forming the joint of the present invention.

The present invention deals with forming joints between wall panels and floor slabs 12. The wall panels 10 are cored, having sidewalls 14 and interior voids 16 extending downwardly from the top surface 18 of the panels. The floor units 12 consist of precast panels 20 which have finished lower surfaces 22 fonning the ceiling of a room and rough cast upper surfaces 24 on which additional fresh concrete is poured to form the finished floor. It will be noted that the precast portion 20 of the floor slab is preferably approximately onehalf the thickness of the finished floor structure. In erecting structures using such panels and slabs, the wall panels 10 are secured in position to suitable foundations or lower floors. Molding strips 30 are then secured along the upper edges of the wall panels.

Although a precast wall panel is illustrated, the joint of the present invention may be used to connect floor panel refers both to precast concrete walls and to other types of walls, such as brick or block walls.

The molding strip 30, illustrated in FIG. 5, may be formed of extruded vinyl or other suitable plastic mate- -rial. The strip 30 has a horizontal web 34 terminating in an upwardly projecting lip 34a, a vertical web-36 terminating in a lip 36a, an intermediate portion 38 connecting the webs 34 and 36, and a lip 40 at the upper V end of the vertical web 36. The intermediate portion 38 may be of any suitable configuration to provide an attractive appearance to the molding which, when installed, simulates a conventional cove molding.

The molding strips 30 are positioned at the upper edges .of the wall panels with the vertical webs 36 of the moldings against the. outer faces of the wall panels, the lip 36a forming a tight seal between the molding and the wall panels 10 engage the lips 40 of the moldings on opposite sides of the panels to temporarily retain the moldings 30 into position. Preferably, the clips 32 are provided at suitable intervals to retain the molding tightly in place until the joint has been completed. This may, for example, be at approximately eight inch intervals.

When the moldings 30 have been secured in position suitable shims such as the blocks 26 are positioned on the top surface of the wall panel 10 and the precast floor slabs 20 are then positioned on the shims, the ends of the floor slabs being at least generally symetrically positioned about the vertical centerline of the wall panel 10. The shims 26 are of sufiicient heighthto maintain an opening 28 of approximately 2 inches between the lower surface 22 of the floor slabs 20 and the upper surfaces 18 of the wall panels 10. Of course, the shims may vary in thickness to compensate for irregularities of the heighth of the wall panels 10. When the floor slabs 20 have been positioned in place the horizontal webs 34 of the moldings contact the lower surface 22 of the floor panels, the lips 34a forming a tight sealing relationship with the floor panels 20.

In order to conserve on the amount of concrete needed to form the joints, sealing plates 44 may be positioned within the voids 16 of the wall panels 10, the plates being carried by rods or wires 46 which extend upwardly to the upper surface 24 of the precast floor slabs where the rods 46 are bent outwardly, as indicated at 48, to engage the upper surface of the floor slabs 22 thereby retaining the plates 44 in position.

At this time fresh concrete 50 is poured onto the upper surface of the floor slabs 20, the concrete flowing into the portions 54 of the wall cavities 16 which are above the stopper plates 44 and also flowing through the spaces 28 between the lower surface 22 of the floor slabs and the upper ends 18 of the wall panels 10 to fill these passages and the space defined by the inner surface of the moldings 30 and the adjacent portions of the wall panels 10 and floor slabs 20. The moldings 30 possess sufficient strength to remain in sealing engagement with the wall and floor panels when the fresh concrete is forced into the region behind the moldings. The upper surface of the fresh concrete 50 is smoothed in the conventional manner to provide a level floor surface 52.

It will be noted that this construction provides both a strong joint and one having attractive appearance.

The concrete which flows through the spaces 28 and into the areas defined by the moldings 30 strengthens the joint giving it additional bending strength over that of a conventional joint. Sincethe molding tightly seals against both the wall and lower surface of the floorslab, the appearance of the joint is not marred by uneven lines. Also, minor irregularities in wall heighth are masked by the molding 30 and do not detract from the appearance of the finished joint.

While only the best known embodiment of the invention has been illustrated and described in detail herein the invention is not limited thereto or thereby. Reference should therefore be had to the appended claims in determining the true scope of the invention.

What is claimed is:

l.v A joint between a precast wall panel having interior voids extending downwardly from the top surface of the panel and at least one precast floor slab in which the floor slab is positioned above the panel with the lateral edge of the slab offset from the vertical centerline of the panel comprising:
