3 Claims.

This invention relates to improvements in anchoring devices for fastening floor joists to masonry walls and for fastening sills to masonry foundations and plates to the tops of masonry walls.

In the construction of buildings from brick, stone or concrete, it is necessary to provide means for anchoring the ends of the floor joists to the Wall for by this means the walls are braced against all forces tending to bulge them outwardly, In brick buildings the walls usually have a thickness that is a multiple of four, and are ordinarily referred to as 8, 12 or 16-inch walls. When the wall is formed from two layers of brick, it is an 8-inch wall and if three layers are employed, it is a 12-inch wall, etc. The several layers are separated by spaces that vary from one quarter of an inch to one inch and are tied together by transversely extending bricks or by metal ties.

The ends of the floor joists are inserted in openings in the inner layer of brick and are anchored by the improved anchoring device that forms the subject of this invention.

One object of this invention is to produce a simple and substantial anchoring device that can be easily applied and which will be very effective. Another object of this invention is to produce an anchoring device of such construction that it will engage several courses of brick, when used with a brick wall, and which will extend between two adjacent joists thereby obtaining a very effective engagement with the Wall.

A still further object of this invention is to produce a simple anchoring bolt for use in securing sills to foundations and plates to the upper ends of walls.

The above and other objects that may become apparent as this description proceeds are attained by means of a construction and an arrangement of parts that will now be described in detail, and for this purpose reference will be had to the accompanying drawing in which the invention has been illustrated in its preferred form, and in which:

Fig. 1 is an elevation showing a portion of the inner surface of a brick wall adjacent the place where two floor joists are anchored thereto;

Fig. 2 is a section taken on line 22, Fig. 1;

Fig. 3 is a section taken on line 3-3, Fig. 2; and

Fig. 4 is a side elevation of the metal strap or bar which forms part of the anchoring device.

In the drawing reference numeral 8 indicates a brick wall which is composed of two layers 01.

brick that have been indicated by reference characters a and b. This wall is constructed in the ordinary manner and the two layers are tied together either by brick or by suitable metal ties which have not been shown. The layer a is provided with spaced openings for the reception of 5 the lower joists 9. The ends of the joists are cut away on a slant as indicated by reference numeral ID in Fig. 2. Secured to each of the joists is a bar or piece of strap iron H, which has been illustrated in Fig. 4, and from which 10 it will be seen that one end is provided with an opening 2 for the reception of an anchor rod !3. The member I l is also provided with a number of holes M for the reception of screws or nails by which it is secured to the joists. One 5 peculiarity of the anchoring device which forms the subject of this invention, is that each device is common to a pair of joists.

Referring now more particularly to Figs. 1 and 3, it will be seen that a bar H is secured to one of the joists near its lower edge and to the other joist near its upper edge. The rod [3 is of such length that it extends between the two bars II and preferably projects a short distance beyond each of the joists in the manner shown, By running the bar l3 diagonally in the manner shown in the drawing, it will extend over three courses of brick when the joists are 10-inch joists and over a smaller number of courses with smaller joists. Attention is also called to the fact that since the bar extends between a pair of joists, all the brick work between the joists serves to hold the bar and in this way a much greater resistance to forces tending to bulge the walls outwardly is obtained than when the ordinary anchoring device is used as this engages only a single brick, or at the most, two bricks, one on one side of each joist. The holes I2 are slightly larger in diameter than the anchoring bar l3, so as to permit the diagonal arrangement illustrated.

Attention is called to the fact that this anchoring device requires very little work to be performed on the parts because the rod I3 is merely a length of ordinary round steel rod, while the bars II are cut from ordinary stock sizes of soft steel and the only operation necessary is to punch or drill the holes I2 and I4. Although it is preferable to have the rod extending diagonally in the manner shown, this is not absolutely neces- 5O sary, as it can extend horizontally and in such a case will engage with only one or two courses of brick, but since the several brick are tied together by the mortar and by mechanical ties that connect the several layers, even such a construction is very strong and may be satisfactory for ceiling joists and in buildings of comparatively small size. Where large buildings, such as stores and warehouses are concerned, the bar I3 is preferably diagonally arranged as shown in the drawing.

Having described the invention what is claimed as new is: V

1. A building construction comprising a wall in whose thickness is incorporated a plurality of layers of brick, a pair of joists having, their ends extending into openings in the inside layer of brick, an anchor bar located in the space between the innermost layer of brick and the next layer, said bar extending diagonally across a plurality of courses of brick and across the ends of the pair of joists, and means for attaching the anchor bar to the joists.

2. A building construction comprising, a wall in whose thickness is incorporated a plurality of layers of brick properly tied together, a pair of joists having their ends extending into openings in the inside layer of brick, an anchor bar located in the space between the innermost layer of brick and the layer adjacent to it, the bar extending diagonally across a plurality of courses of brick and across the ends of the joists, and a hat strap iron piece attached to each joist and each provided at its inner end with a hole for the reception of the anchor bar,

3. In a building having a brick wall composed of a plurality of layers of brick and a pair of V joists having their ends positioned in openings 10 in the inner brick layer, means for anchoring the joists to the wall, said means comprising a piece of iron bar attached to each of the joists and projecting beyond the ends of the joists, one of the attaching bars being secured to its joist above 15 whereby it will cross a plurality of courses oi 20' brick. l
