United States Patent Ofiice 3,121,975 Patented Feb. 25, 1964 3,121,976 EUILDING CONSTRUCTION Y Rush F, Ziegenfelder, 1 3i Locust St., Garden City, NJZ. Filed Dec. 27, 196i), Ser. No. 785% 4 Qlairns. ('Cl. tl--1tl2) This invention relates to precast concrete parapet assemblies, particularly suitable for open-deck motor vehicle parking structures, and its object is to simplify and reduce the cost of such assemblies, and particularly to enable an inexpensive and effective series of steps for applying and securing the primary precast concrete parapet members to the pre-assembled, rigid, structural members at the floor areas of such buildings. The characteristic of the invention resides in the employment of precast arcuate parapets, which may be of any suitable height or length, as for example a height, i.e. width, of 5-6 feet, and a length of 28 feet, or more, and which at each floor may rest upon cantilever extensions of main floor beams, outer end areas of the parapet being held in a special manner by spaced pilasters projected forwardly of the columns which support the main floor beams. The assembly is such that the precast concrete parapets may be hoisted into position, rocked forwardly to engage the special parapet holding elements, and then secured in position against backward movement by the use of simple rear lugs applied to the parapets.
The invention will be described with reference to the accompanying drawings, in which:
FIG. 1 is a perspective view, largely schematic, showing broken away primary elements of the parapet assembly.
FIG. 2 is a broken away isometric view showing one of the parapets as to an end section thereof.
FIG. 3 is a side elevation, largely in section, showing a slightly modified assembly, which is enlarged relatively to FIG. 1, the section being taken vertically.
FIG. 4 is a horizontal section, taken on the line 4-4, FIG. 3.
FIG. 5 is a perspective view, broken away, showing the structure of the two preceding figures, as to one floor hem with its cantilever projection and one of the parapets at its area adapted for pilasters, with the primary parapet holding means of the form shown in FIGS. 3 and 4-.
FIG. 6 is a schematic view, partly broken away, and schematic, showing the parapet assembly applied to three floors of a concrete building structure.
Referring to FIG. 1, I have shown at 1 a primary floor beam having a cantilever extension at 1 the beam being supported by a column 2. It will be understood that for each precast parapet member 3, there will be provided in the building construction spaced cantilever supports such as i At 4, I have shown one of the pilasters, which will be preferably constructed of precast and prestressed concrete, and which will include as an i egral member, a curved parapet guide and abutment 5. At 6 is a concrete walk-way, primarily supported upon the cantilever extension 1*, and which may have secondary support at its outermost side by a cast flange resting upon an inwardly directed projection '7 of the pilaster 4.
The form of parapet employed for its guide and abutment 5 is a precast concrete curved slab of sufficient length to extend between two of the pilasters 4. In the embodiment shown in FIGS. 1 and 2, the parapet 3 has spaced longitudinally extending wall areas 3 providing between them, at each end of the parapet, a recess adapted to receive one of the guide and abutment members 5. The recesses are at 14, FIG. 4.
In the arrangement of elements above described, the guide and abutment elements 5 will be exposed. In
some csaes it is desirable to have tie front surface of each pilaster unbroken to form a straight surface extending vertically of the building. This is provided for by the construction shown in FIGURES 4 and 5, in which the pilaster 8 in each case is formed, intermediate its side faces, with curved parapet guide and abutment elements In such case the parapet will be modified as shown at 9, and by providing seats at the opposite ends of the parapet to receive the guide and abutrnent members 8 Such arrangement also is shown in FIG. 6. Each recess is laterally open at the side facing the end of the parapet, as shown in FIG. 4 and as indicated in FIG. 6.
In FIGURES 3 and 6, the walk-way is formed of two slabs, 1b and II, and opposed sides of the pilaster may be formed with projecting supports 12 to receive the slabs. However, centrally of FIG. 6 I have shown a walkway slab which is similar to that shown in FIG. 1 at 6.
It will be understood that with the pilaster form shown in FIGURES 4 and 5, the guides and abutments are adapted to receive the same type of parapets as shown in FIGURES 1 and 2.
At 16, FIG. 3, I have indicated the front wheel of a motor vehicle to indicate that the bumper, and thus the forepart, of a motor vehicle may project somewhat over the walk-way slab in, between and forwardly of the main supporting columns 2.
The placement and assembly of the parapets, each between opposed pilasters 4, is very simple. Prior to placement of the walk-way elements, each parapet is hoisted and lowered back of the opposed parapet guides and abutments, and then rocked forwardly into position to rest against two opposed cantilever extensions I and also to be received by opposed guides and abutments. The only additional elements required for the ends of each parapet are two applied lugs, one at each of the opposed parapets and such as shown at 15 in FIG. 1.
Having described my invention, what I claim and desire to secure by Letters Patent is as follows:
1. A building structure embodying spaced concrete horizontal floor beams, spaced columns supporting the said beams, a walkway for persons outwardly projected from said columns, said floor beams being formed with cantilever projections of a length substantially that of the width of said walkway and upon which the walkway is mounted, pilasters at the outer ends of a plurality of said cantilever projections and abuttin the same, massive arcuate pro-formed concrete parapets bridging the spaces between said cantilever projections and having their end lower margins abutting and supported by said cantilever projections, said parapets being formed with longitudinal- 1y extending spaced upper and lower wall areas having between them, at each end of the parapet, a recess, and arcuate holding abutments carried by said pilasters and engaging said recesses with lateral holding effect on said parape'ts relatively to the pilasters, whereby when a given parapet is hoisted and lowered back of the abutments between spaced pilasters and is rocked forwardly, it receives support on spaced cantilever projections and the walls of said parapet recesses are brought into engaging registration with said abutments.
2. A building construction in accordance with claim 1, in which the ends of said cantilever projections are of greater width than the pilastcrs abutted thereby and have parapet supporting faces extending substantially away from sides of said pilasters.
3. A building construction in accordance with claim 1, in which the cantilever projections are formed with downwardly and outwardly sloped ends and the parapets have base ends of conforming slope for abutment with said cantilever projections, a substantial gravitational force of the parapets on the cantilever projections being longitudinally of the latter.
4. A building construction in accordance with claim 1, in which the spaced pilasters with their abutments are preformed integral concrete members, a cross section of a given pilaster at an abutment area showing a forma tion having at least one side and lateral projection and 5 which projection is adapted to abut the wall of a recess in the parapet, the distance between the said pilaster lateral projection and the rear face of the pilaster being greater than the Width of the parapet so that the parapet projects beyond the rear face of the pilaster for recep- 10 tion of lugs adapted to abut the parapet.
