Rafter bracket

Abstract

A rafter bracket configured to connect a vertical post to a rafter and beam(s) is described herein. The rafter bracket may include lower vertical side plates, a horizontal plate, and upper vertical side plates. The horizontal plate may be perpendicular to the upper and lower vertical side plates and may separate the upper vertical side plates from the lower vertical side plates. The horizontal plate and lower vertical side plates may create a lower cavity that receives the vertical post. Meanwhile, the rafter may be positioned on one of the upper vertical side plates and positioned between two of the upper vertical side plates and may be angled at an acute angle relative to the vertical post as well as the upper and lower vertical side plates. One or more of the lower vertical side plates may receive lateral plates that define a lateral cavity receiving the beam.

RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 16 / 273,870, filed Feb. 12, 2019, which is a continuation-in-part of U.S. patent application Ser. No. 16 / 113,022, filed Aug. 27, 2018, now U.S. Pat. No. 10,202,766, which is a continuation-in-part of U.S. patent application Ser. No. 15 / 912,203, filed Mar. 5, 2018, now U.S. Pat. No. 10,100,058.

The birdsmouth joint is an indentation cut into the rafter which con...

AI Technical Summary

Benefits of technology

[0007]Without being bound by any particular theory, it is believed that the rafter bracket may provide a number of advantages including: 1) providing a stronger connection method of the roof system to the wall assembly; 2) allows the rafter to retain greater structural integrity because no birdsmouth joint is made, which by necessity reduces the cross sectional area of the rafter significantly; and 3) facilitates faster and cheaper construction due to the fact that multiple specialty cuts are not required for each rafter.

Problems solved by technology

However, such system has a number of disadvantages, particularly if the indentation is not cut correctly, including 1) the strength of the connection of the roof system to the wall assembly; 2) reduced cross-section of the rafter due to the indentation; and 3) time and skill in cutting the indentation.
