Stair expansion joint system with freedom of movement between landings
A stair system with freedom of movement between landings associated therewith includes a connection system configured to connect stairs to a landing associated with a construction, wherein the connection system structurally supports the stairs for safe egress over the stairs while concurrently supporting movement between the landing and a second landing associated with the construction by the stairs in at least one dimension, and wherein the movement supports inter-story drift between the landing and the second landing and removes some force translation between the landing and the second landing.
1. A stair expansion joint system enabling freedom of movement between stairs and a landing, the stair expansion joint system comprising:
a latch system associated with the stairs; and
a catch system associated with the landing, wherein the catch system comprises a rod adapted to connect to the latch system and one or more spring components adapted to connect the catch system to the landing, the rod connected to the latch system and the one or more spring components connected to the landing collectively provide the freedom of movement between the stairs and the landing;
wherein the latch system comprises a landing plate and a stair mount comprising a lip structure adapted to engage the rod, and wherein the catch system comprises a lateral slide connected to a base mount, wherein the rod is disposed to a flange structure on the lateral slide and the one or more spring components connect the lateral slide to the landing.
2. The stair expansion joint system of claim 1 , wherein the landing plate is connected to the stair mount via a hinge enabling the landing plate to rotate about the stair mount, providing access to the latch system and the catch system from the landing.
3. The stair expansion joint system of claim 1 , wherein the base mount is fixed to a beam associated with the landing and the lateral slide is connected to the beam via the one or more spring components.
4. The stair expansion joint system of claim 3 , wherein the lateral slide slidingly engages a channel in the base mount.
5. The stair expansion joint system of claim 1 , wherein the stair mount is one of connected to and integrally formed in a top of the stairs.
6. The stair expansion joint system of claim 1 , wherein the rod comprises an acetal homopolymer resin.
7. A stair expansion joint method enabling freedom of movement between stairs and a landing, the stair expansion joint method comprising:
providing a latch system associated with the stairs; and
providing a catch system associated with the landing, wherein the catch system comprises a rod adapted to connect to the latch system and one or more spring components adapted to connect the catch system to the landing, the rod connected to the latch system and the one or more spring components connected to the landing collectively provide the freedom of movement between the stairs and the landing;
wherein the latch system comprises a landing plate and a stair mount comprising a lip structure adapted to engage the rod, and wherein the catch system comprises a lateral slide connected to a base mount, wherein the rod is disposed to a flange structure on the lateral slide and the one or more spring components connect the lateral slide to the landing.
8. The stair expansion joint method of claim 7 , wherein the landing plate is connected to the stair mount via a hinge enabling the landing plate to rotate about the stair mount, providing access to the latch system and the catch system from the landing.
9. The stair expansion joint method of claim 7 , wherein the base mount is fixed to a beam associated with the landing and the lateral slide is connected to the beam via the one or more spring components.
10. The stair expansion joint method of claim 9 , wherein the lateral slide slidingly engages a channel in the base mount.
11. The stair expansion joint method of claim 7 , wherein the stair mount is one of connected to and integrally formed in a top of the stairs.
12. The stair expansion joint method of claim 7 , wherein the rod comprises an acetal homopolymer resin.
13. A stair system with freedom of movement between the stairs and associated landings, the stair system comprising:
stairs comprising a latch system at a top of the stairs, wherein the latch system comprises a landing plate and a stair mount comprising a lip structure adapted to engage a rod; and
a structure associated with a landing comprising a catch system, wherein the catch system comprises a lateral slide connected to a base mount, wherein a rod is disposed to a flange structure on the lateral slide and one or more spring components connect the lateral slide to the landing, wherein the rod connected to the latch system and the one or more spring components connected to the landing collectively provide the freedom of movement between the stairs and the structure.
14. The stair system of claim 13 , wherein the landing plate is connected to the stair mount via a hinge enabling the landing plate to rotate about the stair mount, providing access to the latch system and the catch system from the landing.
15. The stair system of claim 13 , wherein the base mount is fixed to a beam associated with the landing and the lateral slide is connected to the beam via the one or more spring components.
16. The stair system of claim 13 , wherein the stair mount is one of connected to and integrally formed in a top of the stairs.
17. The stair system of claim 13 , wherein the rod comprises an acetal homopolymer resin.
18. The stair system of claim 13 , wherein the landing comprises an upper landing and further comprising:
a connection system between a bottom of the stairs and a lower landing.
