Fire resistive joint cover system
View Patent ↗A joint cover system is operable to span a gap between two building members, wherein each building member including a first side surface and an end surface. The joint cover system comprises a first base member, a second base member, an intumescent sheet, a first fastener, and a second fastener. The first base member may be positioned on the first side surface of the first building member, and the second base member may be positioned on the first side surface of the second building member. The intumescent sheet may include a first edge positioned between the first base member and the first side surface of the first building member and a second edge positioned between the second base member and the first side surface of the second building member. The first fastener may penetrate the first base member and the first edge of the intumescent sheet. The second fastener may penetrate the second base member and the second edge of the intumescent sheet.
1. A joint cover system operable to span a gap between two building members, each building member including a planar first side surface and a planar end surface, wherein the end surface of the first building member faces and intersects the first side surface of the second building member, the joint cover system comprising:
a first base member positioned on the first side surface of the first building member, the first base member including a lower wall and a spaced-apart upper wall, such that the lower wall is coupled to the first side surface of the first building member;
a second base member positioned on the first side surface of the second building member, the second base member including a lower wall and a spaced-apart upper wall, such that the lower wall is coupled to the first side surface of the second building member, wherein the lower wall and upper wall of the second base member are oriented at a right angle with respect to the lower wall and upper wall of the first base member;
an intumescent sheet with a first edge positioned between the first base member and the first side surface of the first building member and a second edge positioned on the first side surface of the second building member;
a first fastener penetrating a portion of the first base member, the first edge of the intumescent sheet, and the first side surface of the first building member;
a second fastener penetrating a portion of the second base member and the first side surface of the second building member; and
a third fastener penetrating the second edge of the intumescent sheet and the first side surface of the second building member.
2. The joint cover system of claim 1 , further including a cover plate with a right angle bend along the longitudinal axis thereof slidably coupled with the first base member and the second base member.
3. The joint cover system of claim 2 , wherein the first base member and the second base member both include a slot in which the cover plate is slidably coupled.
4. The joint cover system of claim 1 , wherein the intumescent sheet contacts the end surface of the first building member.
5. A joint cover system operable to span a gap between two building members, each building member including a planar first side surface and a planar end surface, wherein the end surface of the first building member faces and intersects the first side surface of the second building member, the joint cover system comprising:
a first base member including a base wall coupled to the first side surface of the first building member;
a second base member including a base wall coupled to the first side surface of the second building member, wherein the base wall of the second base member is oriented at a right angle with respect to the base wall of the first base member;
an intumescent sheet with a first edge positioned between the first base member and the first side surface of the first building member and a second edge positioned on the first side surface of the second building member;
a first fastener penetrating a portion of the first base member, the first edge of the intumescent sheet, and the first side surface of the first building member;
a second fastener penetrating a portion of the second base member and the first side surface of the second building member;
a third fastener penetrating the second edge of the intumescent sheet and the first side surface of the second building member; and
a cover plate with a right angle bend along the longitudinal axis thereof, the cover plate including a first edge slidably coupled with the first base member and an opposing second edge oriented at a right angle with respect to the first edge and slidably coupled with the second base member.
