siding in the city and county of San Francisco and State of California, have invented- ,novel panel unit which I 'shall hereinatter fully describe, and which by its construction lends itself for aggregate use in all situa tions of the building construction, many of which situations and uses it shall herein fully illustrate and describe, in order to render clear the utility and objects of the invention.
The essential object of my invention is to produce a more economical and simplified building .construction. The attainment of these ends will appear in detail in the course of the following de-' scripti'on. I i v l Referring to the accompanying drawings it will be noted that'in the figures the con crete' is either omitted or is shown broken away or is merely indicated. This is for the sake of clearness.

Fig. 16 is a horizontal section of the'same. Fig. 17 is a vertical sectionof the same. Fig. 18 is a fragmentary section, enlarged, showing the junction of three partition panel units.
The letter A is used throughout to designate the panel which is the'unit of my construction. This panel unit, as seen in Fig.
1, is composed of steel and concrete, and may be of any outline or contour to suitthe position for which it is intended- I have herein illustrated it as a quadrilateral The steel compoof rectangular outline. nent of the panel is a frame made up of steel bars 1,,which form the border. These border barsare of flanged or angle-section. Their most common form is'that of a T-section, and in Fig. 1 they are all of this section.
The border bars 1 are united at their angles by small angled-plates 2, and said border bars are further connected by steel rods 3 which may extend in every direction, here shown as being parallel and equi distant, and extending from side to side and end to end. The rods 3 may be connected in any suitable manner to the border bars. An effective connection is to hook them through holes in said border bars. For such connection, the shapes here shown lend themselves perfectly, in' that the T- shapes are setwith their stem flanges extending inward and receiving the hooked ends of the rods 3. Through any of the flanges of the border bars, according to the position in which the panel unit is to 'be employed, bolts 4 are inserted. The steel frame of the panel unit A being thus formed, is ready for the concrete This is applied by pouring or otherwise filling it 1n around the rods 3 and between the'border bars, until the I panel unit is of uniform thickness, and with an even or other shape of' surface. All this workis best, though not necessarily ';done in the shop, the floor or platform surfaceupon' which the panel 'unit is formed being purposely made to give units A are assembled side by side, "their adjacent edges being separated a) leave a space B, between them for conduits of plumbing, heating or wiring. Further, as shown in Fig. 3, wherein three floor panel units are shown, the panel units'lie over a steel bar 6 of channel section, which gives a beam effect, and all said units are jointed overa steel frame support 7 The channel" bar 6 is .for reinforcement'ifnecessary, or a built up beam of other material can be used instead. The conduits B can be formed in any direction, and in any number as may be desired for convenience or. appearance. Also as shown in Fig. 4, two floor panel units may be assembled together with the base of a partition panel unit, all being jointed over a steel frame support 8. Itmay be noted that in these Figs. 2, 3 and 4,
the T-shaped border bars are disposed with their stem flanges extending in the direc- 'tion of the thickness of the panel unit.
Turning now to the construction of the outer walls, Figs. 5, 6,7, 10 and 11 show how the panel units A may be directly combined to form what'may be termed an'aggr-egate panel unit, providing for surface openings a G. In this case,'the panel units A are made of varying shapes and sizes and are directly bolted together, the only variance inconfstructlon, in this case of the outer walls,
7 being that the aggregate panel unit has for 1ts base border-bar a steel bar 9 of Z-section instead of T section, this being for the purpose of better weather protection of joinings when in place as is shown in F igs. 13 and '14. The surface openings C, when in exteriorwalls. may receive any. kind of ornamental treatment, or may be left plain to receive other work, any kind of frame, wood or metal, being applied. I
In Figs. 8, 9 and 12, I show how two such aggregate panel-units of- Figs. 5, 6 and 7, .60

' panel units. The space D, thus left may be occupied by the column or support of a steel frame construct-ion, or it may be fitted with concrete and bars. for a reinforced concrete.
column or support, or it may receive a wooden post in wooden frame construction.
The. channel bar 10 is adapted for oin'amental pilaster treatment.
In Fig. 13 I show two exterior-wall panel units jointed one over the other, the Z-section 9 of the top unit being bolted to the T- sect-io-n 1 of the lower unit. Short plates 11 are bolted to the Z-section 9 and to the flange of the T-section of a floor panel unit,
In Fig. 14 'I show a similar construction to that of Fig. 13, with the addition of two extra but thinner wall panel units back of the exterior wall units, to form an air space E for insulation or damp-proofing. l
Passing now to partition and interior wall construction, the application of the panel units and their aggregate to such construction I show in Fi s. 15, 16,17 and 18. These panel-units may e so assembled as to leave openings such as F, or they may be solid if desired. Three partition panel units or their aggregates may be jointed together as shown inFig. 18,'the edges of the panels being bolt'ed to a channel piece 12 or to the steel frame work. All edges will be completely connected and fastened as shown.'
- As shown in Figs. 4, 13 and 14, the flanges and stems of the border bars of the panel units of the floor, where they join partitions, form other conduits G, which may be filled 1L" completely with cement, wood'or other material or they may receive removable slabs of wood, tile, cement or other material. The entire.floors, walls and partitions may be deafened or may receive the same kind of interior treatment as is used'in other constructions. The partitions may be doubled .to form hollow air spaces-forinsulat-ion orfor ducts or conduits. It is only necessary to apply 'the finishing coat of plaster on them, thereby saving the lathing and brown coats, or they can be left sand finished. The same is true of the exterior walls. The wall, partition and floor panel units can be provided with wooden nailing strips, as in other constructions, to nail moldings, Wainscot base and other trim to them. An additional floor can be constructed under the top floor for insulation, damp-proofing, ducts or con duits, if so. desired, by suspending the same" from the top floor or, supporting it on lower flanges of steel girders or in any otherconvenient, method of construction.
13in Figs. 12 and 18 'or a beam efl'ect as shown at 6 in Fig. 3. These can be formed or shaped to any desired design. The spacesthus formed may be used as conduits orv ducts orthey may he completely filled in ties or anchors to the.
with cement, wood, or any other desirable material. The entire work here described is to form the complete-outer andinner walls and floors of a building. The exterior surfaces need no further treatment. All can be shaped, molded and constructed to meet the requirements of the design and character of the building for which they are intended.
" insuring a better and safer construction.
My invention provides for obtaining molded, sculptured or other ornamental features, constructed and forming an integral part of the product. It provides also an easy means of testing the strength of the products. It lends itself to the provision of easy and accessible conduits or passage-Ways for plumbing and gas pipes, heating and ventilating ducts, wiring for electric lights,
' power and telephone. It requires-no scafbuilding site. The cutting and fitting beingdling,
-The concrete is in a better condition of folding, no lathing, no furring for walls and partitions, and it saves two coats of plaster; nor need the exterior of the building be painted. There are no special forms required at the building, thereby saving expense. It saves loss or waste terials, as these are in a sheltered place and need not be scattered on the premises of the done ina systematic manner prevent waste. Time is also saved, an important item in consideration of occupancy. Time, labor and material are saved in the mixing, hanhauling and pouring of concrete.
strength as it is not subject to'any strain of overloading while it is setting. It preserves the rods from being displaced or bent down, which is unavoidable in old methods where they are subjected. to strain by craftsmen walking on them before the concrete is poured or properly set; nor is the concrete subject to injury by frost. By my invention, the supervision becomes more effective, as the work is more concentrated and is at all times in plain view of the superintendent.
It is often desirable to erect office or other buildings with partitions omitted, to suit possible requirements of tenants. My invention provides for these future partitions in a convenient and economical manner, as all the work may be done outside of the building and other tenants need not be inof useful maconvenienced. This holds true also of alterations and additions.
In my construction no heavy steel girders or supports are required where there are long spans, as the panel units are self-supporting and lighter than the corresponding parts or members in old constructions. All the panel units may be anchored or tied together in such a manner as to form complete ties of thebuilding throughout. My invention also provides a convenient. and simple, economical means for'the construction of bulkheads, retaining walls, roofs and sidewalks.
An important feature of the invention resides in the fact that each panel unit employing as it does a T-shaped border, forms a truss within itself and a complete self supporting construction which requires no fur ther temporary or permanent supports outside of the structural frame work necessary for any building. The flange of the T serves as a guide for straight edging all of my panels. It replaces studding and forms a perfect frame for openings, such as windows, transoms, doors, etc., and the stem of the T lends itself for the ready application of the reinforcing rods.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a building construction, a plurality of panel units, eachunit embodying border, bars of T-shaped'section, members connectingthe stem flanges of said bars, and a 'concrete filling enveloping said members, two of said panel units being arranged in the same plane and in such wise that the adjacent border planes of their bars are separated to leave a-space between them, with other planesof said bars projecting toward each other to form a floor for said space,
and a third of said panel units arranged in a plane perpendicular to that of the other two within the said space and resting on the floor thereof.
2.
