Abstract

A connector is constructed so as to be embedded in a cementitious member and connect a post or other supported member to the cementitious member, such that the connection formed can resist rotational and bending moment forces transmitted to the connector by the post that it supports.

First claim

We claim:

1. A connection for attaching a post to a cementitious member using a connector, the connection comprising:
a. the post, having a bottom surface;
b. the cementitious member having an upper surface;
c. the connector having a lower portion embedded in the cementitious member and an upper portion receiving the post, the connector including:
1. a base member connecting a front member and an opposed back member with the base member being disposed in the cementitious member and with the bottom surface of the post being spaced apart from the base member and with material of the cementitious member disposed within the lower portion of the connector between the bottom surface of the post and the base member;
2. the front member being connected to the base member, the front member extending upwardly from the base member so as to extend out of the upper surface of the cementitious member, the front member having one or more side flanges extending angularly toward the opposed back member and overlapping with portions of the back member where the connector receives the post;
3. the opposed back member being connected to the base member, the opposed back member extending upwardly from the base member so as to extend out of the upper surface of the cementitious member, the back member having one or more side flanges extending angularly toward the opposed front member and overlapping with portions of the front member where the connector receives the post such that together with the front member, the back member and the front member encapsulate at least a portion of the post; and

d. one or more fasteners connecting the post to the connector so that the post, the connector and the cementitious member will resist movement as a unit.

2. The connection of claim 1 , wherein:
the base member has a front edge and an opposed back edge with the front member being connected to the front edge of the base member and the opposed back member being connected to the back edge of the base member.

3. The connection of claim 1 , wherein:
one or more of the one or more fasteners connecting the post to the connector pass through the portions where the front and back members overlap such that the one or more of the one or more fastener pass through both the front and back members and into the post.

4. The connection of claim 1 , wherein:
each of the front and back members has an offsetting bend where the overlap with the other of the front and back member occurs so that the front and back members where they do not overlap can be in flush contact with the post.

5. The connection of claim 1 , wherein:
the one or more side flanges of the front member extending angularly toward the opposed back member and overlapping with portions of the back member, and the one or more side flanges of the back member extending angularly toward the opposed front member and overlapping with portions of the front member overlap along most the length of the portion of the post that is received in the connector.

6. The connection of claim 1 , wherein:
the one or more side flanges extending angularly toward the opposed back member and overlapping with portions of the back member is mechanically interlocked with the back member at the overlap, and the one or more side flanges extending angularly toward the opposed front member and overlapping with portions of the front member is mechanically interlocked with the front member at the overlap.

7. The connection of claim 6 , wherein:
each of the front and back members is formed with a bent tab that interlocks with a corresponding opening on the other of the front or back member to hold the front and back members in fixed relation.

8. The connection of claim 1 , wherein:
the front and back members are formed with lower portions that are embedded in the cementitious member and the lower portions are formed with one or more protrusions that extend outwardly from the front and back members and away from the connector.

9. The connection of claim 8 , wherein:
the lower portions of the front and back members are formed with generally planar portions surrounding the protrusions and the protrusions have upper and lower potions that angle away from the generally planar portions of the front and back members and meet at a juncture located away from the generally planar portions of the front and back members.

10. The connection of claim 9 , wherein:
one or more openings are provided in the one or more protrusions.

11. The connection of claim 10 , wherein:
the one or more openings are provided in the upper portion of the protrusion.

12. The connection of claim 11 , wherein:
only one opening is provided in the upper portion of each of the one or more protrusions and only one protrusion is provided in each of the front and back members.

13. The connection of claim 1 , wherein:
a. one or more tabs are formed from the front and back members that align with the upper surface of the cementitious member, and
b. the front and back members are provided with one or more openings that are disposed just above the tabs that align with the upper surface of the cementitious member.

14. The connection of claim 1 , wherein:
the post rests on one or more seats and the one or more seats are formed from the front and back members of the connector.

15. The connection of claim 1 , wherein:
the front and back members having lower portions embedded in the cementitious member, and the lower portions are formed with one or more stiffening embossments.

16. The connection of claim 15 , wherein:
there are preferably two stiffening embossments in each of the front and back members that are elongated, the two elongated stiffening embossments in each of the font and back members are parallel to each other and extend from the top of the connector to the lower portions of the front and back members.

17. The connection of claim 1 , wherein:
the one or more side flanges of the front and back members are integrally attached to the front and back members throughout a substantial portion of their length.

18. The connection of claim 1 , wherein:
the one or more side flanges of the front and back members are formed with outer edges that have alternating projecting portions and notches where the overlap with the other of the front and back member occurs and the notches in one of the front and back members correspond with the projecting portions in the other of the front and back members.

19. The connection of claim 1 , wherein:
one or more openings are provided in the connector that are disposed just above the upper surface of the cementitious member.

20. The connection of claim 1 , wherein:
the one or more fasteners connecting the post to the connector are threaded fasteners.
