Application August 24,

2 Claims.

This invention relates to a joist and connections therefrom for a floor or a ceiling and aims to provide a novel structure wherein anchor members are secured in a precast joist to accom- 5 modate nailing strips thereon for flooring or a ceiling, and in combination with termite-proof slabs spanning adjacent joists and in sealed relation to the nailing strip and joist, whereby the nailing strip is substantially embedded and fastened to the slab in a termite-proof manner.

It is further aimed to provide such a construction which is relatively inexpensive and which may be expeditiously constructed and which is durable.

Another aim is to provide such a structure as is moisture proof as well as termite-proof.

Various additional objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings:

Figure l is a fragmentary view showing the invention in plan as practiced in connection with a floor;

Figure 2 is a longitudinal sectional View taken on the plane of line 2 2 of Figure l;

Figure 3 is an enlarged sectional view taken at a right angle to Figure 2, and partly broken away;

Figure 4 is a fragmentary plan view showing the invention practiced in connection with both a oor and a ceiling;

Figure 5 is a vertical sectional view taken on the line 5 5 of Figure 4;

Figure 6 is a detail section taken on the line 6Ii of Figure 4;

Figure '7 is a perspective view of a joist and nailing strip thereon, and

Figure 8 is a perspective View of a joist and nailing strips thereon, one for a floor and one for a ceiling.

Referring specifically to the drawings wherein like reference characters designate like or similar parts, any desired number of precast concrete joists I are employed preferably having reinforcing rods' Il therein, the diameter of which may be increased or decreased with an increase or decrease, respectively, in the depth of the joists IB to increase or decrease, respectively, the load capacity of the construction Joists I0 have their ends resting on the walls I2' and are preferably embedded therein, as with mortar.

Nailing strips I2 of wood or any other suitable 1939, Serial No. 291,758

material are disposed on the tops of the joists while in some instance, nailing strips I3 of wood or any other desired material may be disposed against the lower surfaces of the joists. Embedded in the concrete joists Il! are anchors I4 5 and when the nailing strips I3 are employed, anchors I 5 are also embedded therein. The anchors Ill and I5 are preferably of metal and may be straps, flat, round or otherwise and for instance bolts. Said anchors I4 and I5 project beyond the respective ends of the joists and have openings I6 and I'I therethrough through Which nails, bolts or other fastenings may be passed at I8 and I9, respectively, to secure the nailing strips I2 and I3 in place. The anchor members lf3 and I5 may be used at intervals of various distances, as preferred.

Resting on and spanning adjacent joists IIJ at their upper surfaces, are slabs 2l) of concrete or any other material which is vermin proof. d The slabs terminate short of the nailing strip's l2 and provide spaces in which a cementitious sealing agent 2l is disposed while in a plastic state and which is adapted to dry. Such material may be of any desired nature as for instance lmortar or mastic. The same covers the exposed ends of the anchors Ill and fastenings I8, and in effect embeds the nailing strips in the slabs and mounts them in a manner whereby they cannot be attacked by upward travel of termites.

Conventional tongue and groove flooring 22, of wood, or any other desired flooring, may be laid over the strips I2 and nailed or secured thereto as at 23. Preferably a space 24 is left between the flooring and the slabs 20 as shown.

Reverting tothe strips I3, they may be used in any desired manner for the support of a ceiling as best shown in Figures 4, 5, 6 and 8. For instance metallic lathing 25 may be nailed to 40 the strips I3 or any other suitable lathing may be used, and plastering or the equivalent Z applied to such lathing.

Between the joints of different slabs 2B, a suitable seal against termites or the like is provided as at 21, by using mortar, mastic, or the like.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim as my invention:

l. In building construction, concrete joists, anchor members in such joists having portions projecting therefrom, nailing strips for an adjacent structure, said nailing strips being secured to said portions, slabs spanning adjacent joists, 55

and sealing material between the edges of the to said portions, slabs spanning adjacent joists,

slabs and the nailing strips whereby the nailing sealing material between the edges of the slabs strips are substantially embedded. and the nailing strips whereby the nailing strips 2. In building construction, concrete joists, are substantially embedded, and ooring secured anchor members in such joists having portions to the nailing strips above the slabs.

projecting therefrom, nailing strips for an adjacent structure, said nailing strips being secured WILLIAM MOESLY.
