UNITED STATES JOHN LALLY, OF BOSTON, `MASSACHUSE'J!TS.

BUILDING COLUMN.

Application led September 13, 1921,*Seria1 No. 500,385. Renewed September 25, 1923.

To all wlwm t may concem:

Be it known that I, JOHN LALLY, a citizenk of the United States, and a resident of Boston, Suffolk County, Massachusetts, have 5 invented certain new and useful Improvements in Building Columns, of which the following is a specification.

y invention relates to columns of the reinforced concrete type and it is my obproduce a column provided with tie plates for attaching the floor beams in which the tie plates will be solidly attached one to another and to the column. Another object is to provide the tie plates with devices within the column which will increase the vertical resistance of the tie plate and resist any tendency to tip under load.

In the accompanying drawing Fig. 1 is a front, sectional view of my improved column; F ig. 2 a sectional view of the structure of Fig. 1 on the line 2 2- thereof with the plastic filling omitted for clearness of illustration; Fig. 3 a sectional view of a modified form of tie plate construction; and Fig. 4 a view of a further modification.

The column comprises a casing 1, generally of steel tubing or iron pipe, provided with

slots

2, 2 at the points where the tie plates are to be attached. In the forms shown in Figs. 1, 2 and 3 a long tie plate 3 extends through opposed slots and

short tie plates

4 and 5 extend through the remaining slots and abut against the tie plate 3 within the casing. The tie plates are perforated within the casing and U-shaped

clip

6, 6 are hooked through perforations in the

plates

4 and 5 with their legs extending through perforations in the tie plate 3 so that the tie plates may be drawn solidly together by drawing up on the nuts on the threaded ends of the clips. y The casing is then lilled with plastic material, such as concrete, thereby increasing the strength and further uniting the parts.

In order that the vertical resistance of the tie plates may be increased and their liability to tip under load may be prevented thrust pins 7 may be inserted in perforaplates within the casing and spaced from the inner wall thereof, which, when imbedded in the plastic filling, will greatly increase the vertical resistance and tendency 'for the plates to tip in the slots.

As shown in Fig. 3 a perforated reinforcing plate 8 may be secured to the bottom edges of the tie plates by clips 9, 9 engagin perforations in the tie plates 3 and and the reinforcing plate 8. The casing is then filled with plastic material from both ends and the tie plates, and thrust pins if used, are solidly held by being embedded in the plastic material.

If desired the tie plates may be welded to the slots in the casing to increase the weight bearing capacity.

he columns thus produced arev characterized by the absence of protruding brackets to carry the beams as the tie plates lie on the side of the vbeams and are concealed in the floor itself leaving -the column of uniform size from oor to ceiling.

In Fig. 4 I have shown how a single short tie plate 5"may be attached to a cross plate 3 by clip 6 if but one beam is to be carried.

claim:

l. A building column comprising a casing provided with slots, a erforated plate extending through opposedp slots, a perforated tie plate extending through the other slot and abutting the first plate within the casing, a clip passing through perforations in both plates binding the two together and a filling of plasticmaterial within the casing embedding the inner ends of the plates and clip.

2. A building column comprising a. casing provided with slots, a perforated long tie plate extending through opposed slots, short perforated tie plates extending through the other slots with their ends abutting the long tie plate within the casing, clips passing through the perforations in the plates binding them together and a filling of plastic material within the casing embedding the inner ends of the plates and the y clip.

3. A building column comprising a casing provided with slots, perforated tie plates extending through the slots and lying partly within and partly without the casing, thrust pins in the plate perforations away from the inner wall of the casing and a filling of plastic material within the casreinforcing plate, clips ing embedding the inner ends the tie plates and thrust pms.

4. A building cplumn comprising a casing provided with slots, perforated tie 5 plates extending through the slots and secured together within the casing, a. reinforcing plate within the casing secured to the lower edges of the tie plates and a plastic lling within the casing embedding the tie plates and reinforcing plate.

In testimony whereof I have hereunto subscribed my name.

JOHN LALLY.
