In addition, the wall plate is fixed in a large wall specification from the outdoor side across the adjacent column members, and the indoor side surface of the wall plate is exposed to an indoor space.

  In addition, “CLT” in the present invention is an “orthogonal laminated plate” in the JAS standard, and was adjusted by joining and bonding in the length direction with the fiber plates being substantially parallel to each other. Is a plate material in which the fiber directions are arranged in parallel or bonded in the width direction so that their fiber directions are substantially parallel to each other, and are laminated and bonded mainly with their fiber directions being substantially perpendicular to each other to have a structure of three or more layers. .

  Preferably, a floor plate is formed by installing a floor plate made of CLT having the same dimensions as the wall plate on the floor assembly.

  Preferably, a roof base is formed by installing a field board made of CLT having the same dimensions as the wall board on the rafter of the roof set.

  Preferably, the base plate has a lower surface exposed to an indoor space.

  Preferably, a ceiling plate made of CLT having the same dimensions as the wall plate is installed on the upper surface of the beam member laid between the column heads of the column member to form a cabin space with the ceiling plate as a floor surface. It is characterized by.

  Preferably, a horizontal rail that is a base material of the wall plate and between which the desired article can be placed is provided between the column members.

  According to the housing structure of the present invention, the CLT (Cross Laminated Timber) wall plate is fixed to the wooden frame structure formed by assembling the pillar material and the beam material with a large wall specification from the outdoor side. Horizontal housing strength can be borne, and a housing structure with sufficient structural strength can be obtained. And since the surface on the indoor side of the wall plate is exposed to the indoor space, the amount of storage can be increased as compared with the structure in which the indoor side of the pillar material is covered with the finishing material, and the space also increases in appearance. Can be given. And since a wall board is comprised by CLT, the design property of the part exposed to indoor space can be made excellent, and it can be set as a design integral with a pillar and a beam.

  Also, according to the preferred form of the housing structure, the floor board is formed by installing a floor board made of CLT having the same dimensions as the wall board on the floor assembly, so the floor board and the wall board are prepared separately in advance. There is no need to keep it. In particular, by storing CLT plates in advance, it is possible to prepare for a case where a housing structure is urgently needed, such as a temporary housing at the time of a disaster. In addition, after dismantling the housing structure, it can be stored again and used again when the housing structure becomes necessary. The same size facilitates inventory management and emergency transportation management.

  Further, according to another preferred form of the housing structure, a roof base is formed by installing a base plate made of CLT having the same dimensions as the wall board on the rafter of the hut set, so that in the case of the floor board of the previous paragraph In the same manner as above, it is not necessary to prepare the field board and the wall board separately in advance, and stockpiling, inventory management, transportation management, etc. are facilitated.

  Furthermore, by exposing the lower surface of the field board to the indoor space, there is no need to provide a separate decorative material, so that the material cost can be reduced and the space can be made wider.

  Furthermore, according to another preferred form of the housing structure, the ceiling plate made of CLT having the same dimensions as the wall plate is installed on the upper surface of the beam material, and the roof space with the ceiling plate as the floor surface is formed. The space can be used as a loft or shed storage. And since this ceiling board consists of CLT of the same size as a wall board, it is not necessary to prepare a ceiling board and a wall board separately beforehand like the case of a floor board and a field board, Stockpiling, inventory management, transportation management, etc. become easy.

  And according to the preferable form of the housing structure, the wall plate is fixed to the column member by providing a crosspiece between the column members and providing a crosspiece on which the desired article can be placed on the upper surface. In addition, since the wall plate is fixed more firmly by being fixed to the horizontal rail, the wall plate can bear the structural strength in the horizontal direction, and a strong housing structure can be obtained. Further, since the horizontal rail is a base material for the wall plate and can also be used as a shelf plate, the storage can be made more convenient without providing a separate shelf plate.

A handrail 21 for preventing falls is provided at the boundary between the area where the ceiling plate 6 is installed and the atrium, and a ladder or the like (not shown) is provided so that the shed space can be used as loft or shed storage. . And the lower surface of the ceiling board 6 is exposed toward the lower living space, and a resident can visually recognize the ceiling board 6 of CLT as it is.

  As shown in FIGS. 2 and 8, the field board 5 is a plate material laid on the rafter 18 and fixed to the rafter 18 with screws or the like. It is a CLT plate material of 1000 mm and a thickness of 36 mm. In addition, it is CLT of thickness 36mm on the dimension of a roof, Comprising: The field board 5 cut | disconnected smaller than said dimension is laid in part. A heat insulating material 22 is laid on the base plate 5, and a waterproof sheet 23 and a folded roof 24 are further laid to complete the roof. No decorative material or the like is provided on the indoor side of the field plate 5, and the field plate 5 is exposed in the indoor space.

  As mentioned above, the floor board 4, the wall board 3, the ceiling board 6, and the field board 5 which concern on the housing structure 1 of this embodiment are respectively the same dimensions except for the part which needs to change the magnitude | size for convenience of arrangement | positioning. It is formed by CLT. In this way, by basically forming the same material with the same dimensions, it is not necessary to separately manage the floor board 4, the wall board 3, the ceiling board 6, and the field board 5. In particular, it is necessary to stock up temporary housing materials in advance to prepare for a case where the housing structure 1 is urgently needed, such as a temporary housing at the time of a disaster. Since the board 3, the ceiling board 6 and the field board 5 have one kind in principle, the cost of inventory management and the cost of transportation management can be reduced. In addition, since some of the dimensions that do not match each other are smaller than the above basic dimensions, some of them can be easily used as each plate material by cutting on site. Further, even when the housing structure 1 is dismantled, the plate material basically has the same dimensions, so that it can be stored again and used again when the housing structure 1 is needed.

  In addition, CLT is excellent in strength performance and heat insulation performance, and basically covers floors, walls, ceilings, roofs, etc. with CLT, so that the strength of the housing structure 1 can be increased. Thermal insulation can also be improved. And since the floor board 4, the wall board 3, the ceiling board 6, and the field board 5 are each exposed toward the living space, the entire living space is a space surrounded by CLT wood, and a decorative material is provided. It can be made a space with excellent design.

  Needless to say, the embodiment of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the scope of the idea of the present invention.

  The house which concerns on this invention can be used suitably as a structure of a temporary house, for example.
