Wooden house

Abstract

According to an embodiment of the present invention, a wooden house comprises a wall structure, a ridge structure formed on the wall structure, a rafter structure formed on the ridge structure, and a roof structure formed on the rafter structure. Each of the wall structure, the ridge structure, and the rafter structure includes a lumber stack. The lumber stack includes a plurality of wooden boards stacked in tiers, with wider sides facing each other. Each of the wooden boards is shaped substantially as a cuboid.

1 . A wooden house, comprising:
 a wall structure;   a ridge structure formed on the wall structure;   a rafter structure formed on the ridge structure; and   a roof structure formed on the rafter structure,   wherein the wall structure includes a first lumber stack, the ridge structure includes a second lumber stack, and the rafter structure includes a plurality of third lumber stacks,   wherein each of the first lumber stack, the second lumber stack, the plurality of third lumber stacks includes a plurality of wooden boards,   wherein the wooden boards of the first lumber stack are stacked one on another in a first direction,   wherein the wooden boards of the second lumber stack are stacked one on another in a second direction substantially perpendicular to the first direction, the second lumber stack extending in a third direction substantially perpendicular to the first and second directions,   wherein the third lumber stacks of the rafter structure are arranged in the third direction.   
     
     
         2 . The wooden house of  claim 1 , wherein the wall structure includes a first wall and a second wall and is shaped substantially as a polygonal column, wherein the first wall and the second wall each include a plurality of lumber stacks stacked up in tiers so that alternating rows of the lumber stacks of each of the first and second walls are offset with respect to each other and so that the respective ends of the lumber stacks in the first wall are engaged with the respective ends of the lumber stacks in the second side wall. 
     
     
         3 . The wooden house of  claim 2 , wherein each of the lumber stacks of each of the first and seconds walls has a cut end at a corresponding edge of the wall structure where the first wall meets the second wall, and wherein the cut end is even with a surface of the first or second wall. 
     
     
         4 . The wooden house of  claim 1 , wherein the ridge structure is placed midway on the wall structure to cross the first wall and the second wall of the wall structure. 
     
     
         5 . The wooden house of  claim 1 , wherein the rafter structure connects a top of the wall structure and a top of the ridge structure,
 wherein the third lumber stacks of the rafter structure are spaced apart from each other at a predetermined distance to form multiple rafters.   
     
     
         6 . The wooden house of  claim 5 , wherein the roof structure includes:
 a first lumber array layer including multiple wooden boards arranged widthwise of the ridge structure or lengthwise of each rafter on the rafter structure to cover opened portions between the rafters of the rafter structure;   a second lumber array layer including multiple wooden boards arranged widthwise of each rafter or lengthwise of the ridge structure on the first lumber array layer; and   a third lumber array layer including multiple wooden boards widthwise of the ridge structure or lengthwise of each rafter on the second lumber array layer, and wherein the first lumber array layer, the second lumber array layer, and the third lumber array layer together form a roof.   
     
     
         7 . The wooden house of  claim 6 , wherein the rafters and the roof are fastened by inserting screws in a bottom-to-top direction through the rafter structure into one of the first to third lumber array layers. 
     
     
         8 . The wooden house of  claim 6 , wherein a direction in which the multiple wooden boards of one of the first to third lumber array layers are arranged is substantially perpendicular with a direction in which the multiple wooden boards of another of the first to third lumber array layers are arranged. 
     
     
         9 . The wooden house of  claim 1 , wherein the stacked wooden boards of the lumber stack of the wall structure are firmly joined together by screws passing through at least two of the wooden boards in a direction and threaded into another one of the wooden boards. 
     
     
         10 . The wooden house of  claim 1 , wherein a direction in which the wooden boards of one of the wall structure, the ridge structure, and the rafter structure are stacked is substantially perpendicular with a direction in which the wooden boards of another of the wall structure, the ridge structure, and the rafter structure are stacked. 
     
     
         11 . A wooden house, comprising:
 a wall structure;   a ridge structure formed on the wall structure;   a rafter structure formed on the ridge structure; and   a roof structure formed on the rafter structure,   wherein the roof structure includes:   a first lumber array layer including a plurality of first wooden boards arranged widthwise of the ridge structure to cover opened portions between rafters of the rafter structure; and   a second lumber array layer disposed on the first lumber array, the second lumber array layer including a plurality of second wooden boards arranged to cross the plurality of first wooden boards.
