Dec. 10, 1957 R. KENK JOIST ANCHOR Filed Jan. 28, 1955 INVENTOR. ROW/MM KEMM.
ATTORNEYS JOIST ANCHOR Roman Kenk, Alexandria, Va.
Application January 28, 1955, Serial No. 484,734
2 Claims. (Cl. 20--94) The present invention relates to a joist anchor, and more particularly to a joist anchor for repairing the deteriorated building walls supported end portions of wooden joists while in their supporting positions.
The primary object of the present invention is to provide a joist anchor for repairing a decayed or rotted end portion of a joist where it extends into an opening in a wall for support by the wall.
Another object of the present invention is to provide a joist anchor for repairing the deteriorated end portion of a wooden joist where it is engaged in a wall opening without removing the floor or subfloor supported by the joist and providing by this method economical repairs to existing buildings.
These and other objects and advantages of the method of the present invention will be more fully apparent from the following description when taken in connection with the accompanying drawing, in which:
Figure 1 is a view in perspective of the joist anchor according to the present invention,
Figure 2 is a fragmentary sectional view in perspective showing one of the deteriorated end portions of a joist removed and repaired with another end portion of a joist treated so as to be repaired by the joist anchor of the present invention,
Figure 3 is a side view in cross section showing how the hanger is inserted into the wall opening formerly occupied by the removed end portion of the joist and raised to embrace the remaining portion of the joist, as shown in dotted lines, and
Figure 4 is a vertical view in cross section on line 44 of Figure 2 showing the joist repaired and assembled joist anchor of the present invention.
In employing the joist anchor of the present invention, the deteriorated building wall supported end portion of a wooden joist 10 is first removed. This is effected by either cutting or severing from the wood joist 10 an end portion of a size to include the part resting on the building wall 11 and a further part of at least a length corresponding to the extension 14 of a U-shaped hanger 13 of the joist anchor according to the present invention. This cutting may be done by making a vertical single cut as shown by the full line 12 in Figure 3.
The U-shaped hanger 13 includes a bight 19 and a pair of legs 17 and 18 rising from the bight 19. The extension 14 is also U-shaped and includes a bight 7 and a pair of legs 8 and 9 rising from the bight 7, the extension projecting longitudinally from one end of the hanger bight 19 and legs 17 and 18. The legs 8 and 9 of the extension are cut obliquely, as indicated by the numeral 30.
The joist anchor is positioned so that the extension 14 enters the space formerly occupied by the removed joist end portion with the bight 7 resting upon the building wall, whereupon the part 15 of the legs 17 and 18 of the hanger 13 inwardly and adjacent the other ends is caused to embracingly receive the adjacent part 16 of the wooden joist between its legs 17 and 18 with the bottom of the joist 3 titted States Patent part 16 engaged by the bight 19. This may be done by positioning the hanger on the remaining part of the wooden joist so that the legs receive such part and then longitudinally sliding the extension 14 into the space formerly occupied by the removed end joist portion.
With the hanger 13 in place on the wooden joist 10 the hanger and joist are secured together in assembled relation by fastening elements or bolts 22 and 23 which extend through registering holes 20 and 21. formed in the legs 17 and 18 of the hanger 13 adjacent to and inwardly of the other end of the hanger and holes formed in the adjacent part of the wooden joist 10, as shown in Figures 2 and 3.
It is to be noted that the holes 20 and 21 in the legs 17 and 18 of the hanger 13 are located contiguous to the upper edges thereof, so that the bolts 22 and 23 when extending therethrough and the adjacent part of the wooden joist 10 provide a strong and sturdy attachment. The wood of the joist 10 in the area where the bolts 22 and 23 secure the hanger to the joist is less liable to be rotted than in any other area closer to the wall 11.
It may be necessary to first provide a jack or brace (not shown), for the joist to be levelled before repair and then have a further jack for forcing the hanger into assembled relation on the joist.
The extension 14 is offset with respect to the hanger 13 and is made narrower than the hanger 13 and has its outside dimension equal to or less than the thickness of the joist so as to enable it to enter the hole in the wall formerly filled by the joist end.
The joist anchor of the present invention may be used to repair existing houses or may be used in the construction of new buildings, and when so used in a new building provides an extension for each of the joists to keep the ends of the joist from direct contact with the wall, thereby preventing moisture from the wall reaching the joist and causing it to decay.
What is claimed is:
1. A joist anchor comprising an upstanding U-shaped hanger including a bight and a pair of legs rising from said bight, and a U-shaped extension including a bight and a pair of legs rising from the last named bight projecting longitudinally from one end of the hanger bight and legs, the legs of said extension being narrower than said hanger and cut obliquely, said extension being adapted to enter a space provided upon a building wall for the support of a joist end portion with the bight resting upon said building wall and said hanger being adapted to embracingly receive an end portion of a wooden joist between the part of the legs inwardly and adjacent the other ends with the bottom of the joist engaged by the adjacent part of the bight, the hanger legs having registering holes located contiguous to the upper edges and adjacent to and inwardly of the other ends thereof for extension therethrough and a joist end portion when received therebetween of securing elements.
2. A joist anchor according to claim 1 in which said extension is offset with respect to said hanger and being narrower than said hanger.
