Cross-laminated timber (clt) panel connection

Abstract

A Cross-Laminated Timber (CLT) connection is provided that can be used to connect at least two CLT components such as CLT panels. The CLT joint includes a first CLT component, a second CLT component, and a spline. The first CLT component includes a first recessed channel. The second CLT component includes a second recessed channel. A first end of the spline is configured to nest within the first recessed channel. A second end of the spline is configured to nest within the second recessed channel. The CLT panel includes a first CLT side and a second CLT side. The first CLT side includes a recessed channel. The second CLT side may be opposite the first CLT side and includes a grooved extension. The grooved extension and the recessed channel have complimentary patterns. A CLT panel system is also provided comprising a plurality of CLT panels.

         8 . A Cross-Laminated Timber (CLT) panel comprising:
 a first CLT side including a first recessed channel; and   a second CLT side including a second recessed channel, the first recessed channel is configured to receive a first end of a first spline and the second recessed channel is configured to receive a second end of a second spline.   
     
     
         9 . The CLT panel of  claim 8  further comprising a third CLT side including a third recessed channel and a fourth CLT side including a fourth recessed channel, the third recessed channel is configured to receive a third end of a third spline and the fourth recessed channel is configured to receive a fourth end of a fourth spline. 
     
     
         10 . The CLT panel of  claim 8 , wherein the CLT panel is prefabricated. 
     
     
         11 . The CLT panel of  claim 8 , wherein at least one of the first end of the first spline and the second end of the second spline has a step-down profile. 
     
     
         12 . The CLT panel of  claim 8 , wherein at least one of the first end of the first spline and the second end of the second spline includes at least one seal. 
     
     
         13 . The CLT panel of  claim 8 , wherein the first recessed channel and the first end of the first spline allow for displacement. 
     
     
         14 . The CLT panel of  claim 8 , wherein the second recessed channel and the second end of the second spline allow for displacement. 
     
     
         15 . The CLT panel of  claim 8 , wherein the CLT pane is comprised of pieces of dimensional lumber glued and stacked in multiple crosswise layers. 
     
     
         16 . The CLT panel of  claim 8 , wherein the first spline and the second spline are each comprised of wood. 
     
     
         17 . A Cross-Laminated Timber (CLT) panel system comprising:
 a first CLT panel including a first CLT horizontal side including a first recessed channel and a first CLT vertical side including a second recessed channel;   a second CLT panel including a second CLT horizontal side including a third recessed channel and second CLT vertical side including a fourth recessed channel;   a third CLT panel including a third CLT horizontal side including a fifth recessed channel and a third CLT vertical side including a sixth recessed channel; and   a fourth CLT panel including a fourth CLT horizontal side including a seventh recessed channel and a fourth CLT vertical side including an eighth recessed channel extension;   a first spline configured to connect the first recessed channel with the seventh recessed channel;   a second spline configured to connect the second recessed channel with the fourth recessed channel;   a third spline configured to connect the third recessed channel with the fifth recessed channel; and   a fourth spline configured to connect the sixth recessed channel with the eighth recessed channel.   
     
     
         18 . The CLT panel system of  claim 17 , wherein at least one of the first spline, the second spline, the third spline, and the fourth spline include at least one seal. 
     
     
         19 . The CLT panel system of  claim 17 , wherein the first spline, the second spline, the third spine, and the fourth spline each have step-down profiles.
