3 Claims. (CI. 20-94) v movement influenced by high velocity winds,
floods and severe storms.
It has been the practice for many years to support the joists upon the foundation sill without any special attaching expedients. The weight of the building structure serves to retain its position upon the foundation, but reliance upon weight alone is not entirely satisfactory in frame buildings subjected to high velocity winds, floods and severe storms. Even toe-nailing the joist to the foundation sill does not appreciably retard movement under such unusual strains and stresses so that it is a common occurrence for frame structures to sway, move and even become detached from their foundation under unusual climatic conditions.
This is especially true in cyclonic areas and when frame structures are subjected to floods. Under such conditions, frame structures have floated away or become dislodged from their foundation when the water mark exceeds the foundation height. This is primarily due to the fact that the frame structures are not anchored directly to the foundation or the foundation sill. While this condition is not apt to occur in brick structures, yet it would be highly desirable to anchor the joists therein to preclude any possible movement, sway or dislodgment.
It is worthy of note that joist anchors or braces may be advantageously used on the floors above the foundation, since the joists usually rest on a double plate which may be wood timbers nailed to the vertical struts. Rather than toe-nailin the joists to the double plate that supports the floors superposed above the foundation, joist anchoring brackets embodying features of the present invention can be advantageously used for this purpose.
This will eliminate defects due to severe strains such as high wind velocities and excessive weights constructed high above the foundation of the structure. Toe-nailing is not a very practical nor effective anchoring expedient. It has been resorted to in building structures merely to initially retain the joists in position prior to the application of the flooring as well as the walls to the frame. This type of anchor is not sufficiently durable to preclude sway, movement or dislodgment of a building structure and is not intended to serve that purpose.
One object of the present invention is to provide an improved anchoring brace or bracket to securely tie building joists to the foundation or supporting plates.
Another object is to provide an improved building joist bracket of simple and inexpensive construction.
. Still another object is to provide a joist bracket that will effectivel serve as an anchor of a building structure to the foundation as well as superposed supporting plates, thereby securely anchoring the entire super-structure to the foundation.
A further object is to provide a simple and' inexpensive joist bracket that serves as an anchor therefor to struts that extend downwardly therealong and to the corner posts comprising the framework of a building structure.
A still further object is to provide a simple and effective joist bracket that engages the entire upper ed e of the joists to eifect their attachment to the supporting sill or plates.
Still a further object is to provide a simple, inexpensive and durable joist anchoring bracket stamped or otherwise shaped from a single sheet of material to provide anchoring and retaining flanges to effectively connect joists to their supporting sills or plates.
Other objects and advantages will appear from the following description of an illustrative embodiment of the present invention.

The structure selected for illustration comprises, in this instance, a concrete foundation Ill which defines the basement space of a building structure and serves as a support therefor. Before the concrete foundation l sets, foundation sill anchoring bolts H are immersed in the soft concrete In so as to be rgidly held therein to afford the'attachment of sills or plates l2-l3 thereto. It is customary to provide a double sill or plate |2-|3 which is ship-lapped to provide a corner joint as at "-1 in conjunction with corresponding sills or plates |6-| 1 extending at right angles thereto to conform with the walls of the foundation l0. 7
It should be observed, however, that the double foundation sills or plates |2-|3 are optional and that the number thereof is immaterial and depends largely upon the requirements of each building structure. In any event, however, the sills or plates |2-| 3 are anchored to the foundation III by the bolts II that have nuts and washers |8|9 secured to the upper extremity of the bolts II. This facilitates and effectively secures the foundation sills |2-|3 to the concrete foundation Ill. The foundation sill or plate l3 supports the joists which are uniformly spaced therealong to extend over the entire expanse of the floor area.
The joists 20 may have 16", 20" or 24" nails depending upon the dictates of commercial practice and the requirements of any installation. In order to effectively install the joists 20 to sill plates |3 that are horizontally spaced to conform with the length of the joists 20, angle brackets 2| are provided for this purpose. The joist anchor brackets comprise, in this instance, a sill plate member which is stamped or otherwise shaped from sheet steel or other suitable material to provide an angular webbed portion 22 having a rectangular base flange 23 bent therefrom to define an edge 24 to extend normally to the web 22.
An upstanding flange 25 extends from the bent edge 24 to terminate in an upper extreme edge 25 projecting beyond the highest point 21 of the web 22 to which it is joined by the edge 28. It should be noted that the lower extremity extreme edge 23 of the upwardly extending flange 25, projects beyond the web edge 24 to define a right angularly offset base flange extending above the base flange 23 of the web 22 for overlapping contact therewith. The base flange 30 of the upwardly upstanding vertical flange 25 is joined thereto by the edge 3| which coincides with the extreme linear edge 32 of the base flange 23 constituting a part of the web 22. With this arrangement it will be observed that the bracket 2| is stamped from a single sheet of material to provide a rigid upstanding bracket having an overlapping horizontal base flange 23-33 and a vertical attaching flange 25, the flanges 25 and 23-30 being reinforced by the triangular web 22 extending therebetween.
In utilizing the joists 20 to rigidly support the vertical studs 33 or corner posts 34' for support upon the foundation sill plates l3 or girders 34, the angle brackets 2| have their base flanges 23-30 resting on the horizontal sill plate or girder 34 for attachment thereto by means of a plurality of suitable fasteners such as nails 35 projecting through apertures 36 and 31 in the overlapping base flanges 23-30. The vertical flange 25 is attached to the vertical surface of the studs 33 or comer posts 34' by attachment thereto by means of any suitable fasteners such as nails 38 that project through a plurality of apertures 39 extending through'the vertical flange 25.
In anchoring the joists 20 to the foundation sill plates |2-|3 or to the girders 34, the vertical flange 25 is oilset at an angle proximate to the upper extremity 26 thereof along a line coincident with the point of meeting 21 of a web edge 40 with the vertical flange 25 (Figur 1), thereby defining a horizontally offset flange 4| that engages the top surface 42 of the joists 20. Suitable fasteners such as nails 43 project through the top row of apertures 39 provided in the vertical flange 25. -It is possible, therefore, to provide the angular bracket 2| to support the vertical stud 33 on one side and another angular bracket 2| with the horizontally offset top flange 4| anchored to the same girder 34 for attachment to adjacent joists 20 to provide a rigid and securely anchored vertical supporting stud 33 and horizontal joists 20 (Figures 2 and 3).
Where studs 33 are spaced from each other without any adjacent joists 20, oppositely disposed angle brackets 2| are anchored to the vertical studs 33 and the supporting horizontal girder 34 (Figure 5). Corner posts 34 are simllarly supported and anchored against side-sway by providing two angle brackets 2| disposed at right angles to each other for anchored attachment to the intersecting girders 34 and the contiguous surfaces of the corner posts 34' (Figure 5). Similarly, the combined corner posts 34' with an adjacent joist 20 can be mounted and securely anchored in the manner described in connection with the arrangement shown in Figure 3.
Where joists 20 are disposed along the edges of the foundation sill plates |2 or l3 or both (Figure ID), the end joists 20 may be supported with an angle bracket 2| that has an upper horizontally offset flange 4| to effect engagement of the vertical as well as top horizontal surface thereof. Where flooring 44 is attached to the horizontal top surface 42 of the joists 20, the fasteners such as nails 43 are preferably driven through the flooring 44 for registry with the top row of apertures 39 in the vertical flange 25 that has been angularly offset to provide the flan e ll. e e nails will serve the dual purpose of anchoring the floor boards 44 and the angle brackets 2| to the joists 20. Thus, a single piece of angle bracket of simple and improved construction has been provided that is adaptable to vertical studs 33 or corner posts 34, and joists 20 that may be spaced relative to each other or disposed in direct contact according to the requirements of any particular installation.
In the modified embodiment shown in Figures 6 to 9 inclusive, the double angle bracket 2| is combined as a unitary and integral unit. In this instance, there is provided oppositely disposed angular webs 22 which have two horizontally extending base flanges 23' joined thereto along the edges 24'. Vertical flanges 25 are disposed in spaced parallel relation to each other and terminate in an integral top flange 4| so as to define an inverted substantially U-shaped member which will freely receive the joists 20' therein when the base flanges 23' are rigidly attached to the foundation sill plates i2-I3 by resort to suitable fasteners such as nails 35'. Overlapping base flanges 30' are bent from the vertical flanges 25' to project in the direction of the base flanges 23' and contact therewith.
It will be observed that this structure aifords the rigid vertical support of joists 20 for anchored attachment to foundation sill plates I2|3 or girders 36 without any possibility of vertical or side-sway in on direction or another. Apertures 36' and 39' are provided in the base flanges 23'25', respectively, and also there are a plurality of apertures 39', in this instance two, provided through the top horizontal flange 4| that is common to the parallel spaced vertical flanges 25'.
The apertures 39' in the top flange Ill preferably receive the fasteners such as nails that project through the floor boards it or nails may be driven therethrough independent of the floor boards ll depending upon the dictates of commercial practice. The double angle brackets 2| are stamped or otherwise shaped from a single piece of material to provide a rigid, inexpensive and exceedingly durable anchoring bracket for joists 20 that are secured to the foundation sill plates l2--|3 or to girders 34.
Various changes may be made in the embodiment of the invention herein specifically described without departing from or sacrificing any of the advantages of the invention or any features thereof, and nothing herein shall be construed as limitations upon the invention, its concept or structural embodiment as to the whole'or any part thereof except as defined in the appended claims.
