Cross-lamination timber (clt) joint

Abstract

A Cross-Laminated Timber (CLT) joint is provided that can be used to connect at least two CLT components such as CLT panels. The CLT panel can be prefabricated and pre-assembled, and can be easily and quickly installed. The CLT joint includes a first CLT component and a second CLT component. The first CLT component includes a recessed channel. The second CLT component includes a grooved extension. The grooved extension and the recessed channel have complimentary patterns. The grooved extension is configured to nest within the 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.

         4 . The CLT joint of  claim 3 , wherein the at least one seal is grooved and set into the grooved extension. 
     
     
         5 . The CLT joint of  claim 1 , wherein the recessed channel and the grooved extension are configured to create a space between the first CLT component and the second CLT component when the grooved extension is nested in the recessed channel. 
     
     
         6 . The CLT joint of  claim 3 , wherein the seal is part of a membrane that is adhered to the grooved extension. 
     
     
         7 . A Cross-Laminated Timber (CLT) panel comprising:
 a first CLT side including a recessed channel; and   a second CLT side including a grooved extension, the grooved extension and the recessed channel having complimentary patterns.   
     
     
         8 . The CLT panel of  claim 7  further comprising a third CLT side including a second recessed channel and a fourth CLT side including a second grooved extension, the second grooved extension and the second recessed channel having complimentary patterns. 
     
     
         9 . The CLT panel of  claim 7 , wherein the grooved extension has a stepped down profile. 
     
     
         10 . The CLT panel of  claim 7 , wherein the panel is comprised of pieces of dimensional lumber glued and stacked in multiple crosswise layers. 
     
     
         11 . The CLT panel of  claim 10 , wherein the at least one seal is grooved and set into the grooved extension. 
     
     
         12 . A Cross-Laminated Timber (CLT) panel system comprising:
 a first CLT panel including a first CLT horizontal side including a first grooved extension and a first CLT vertical side including a first recessed channel;   a second CLT panel including a second CLT horizontal side including a second grooved extension and second CLT vertical side including a third grooved extension;   a third CLT panel including a third CLT horizontal side including a second recessed channel and a third CLT vertical side including a third recessed channel; and   a fourth CLT panel including a fourth CLT horizontal side including a fourth recessed channel and a fourth CLT vertical side including a fourth grooved extension;   the first grooved extension configured to connect with the second recessed channel;   the first recessed channel configured to connect with the third grooved extension;   the second grooved extension configured to connect with the fourth recessed channel;   the third recessed channel configured to connect with the fourth grooved extension.   
     
     
         13 . The CLT panel system of  claim 12 , wherein the first grooved extension and the second recessed channel are configured to be a tongue and groove type connection. 
     
     
         14 . The CLT panel system of  claim 12 , wherein the second grooved extension and the fourth recessed channel are configured to be a tongue and groove type connection. 
     
     
         15 . The CLT panel system of  claim 12 , wherein the first recessed channel and the third grooved extension are configured to be a tongue and groove type connection. 
     
     
         16 . The CLT panel system of  claim 12 , wherein the third recessed channel and the fourth grooved extension are configured to be a tongue and groove type connection. 
     
     
         17 . The CLT panel system of  claim 12 , wherein the first grooved extension and the second groove extension each have a stepped down profile. 
     
     
         18 . The CLT panel system of  claim 12 , wherein the second CLT vertical side and the fourth CLT vertical side each include at least one seal. 
     
     
         19 . The CLT panel system of  claim 12 , wherein the first grooved extension and the second grooved extension each include at least one seal. 
     
     
         20 . The CLT panel system of  claim 19 , wherein the at least one seal is grooved and set into the first grooved extension and the second grooved extension. 
     
     
         21 . A method of connecting a CLT panel system comprising:
 receiving a first CLT panel, a second CLT panel, a third CLT panel, and a fourth CLT panel, wherein each panel may include:
