Abstract

[Problem] To provide a construction method for improving the construction efficiency of a wooden house with a room A that is made up of an open-ceiling space. [Solution] In a wooden house that uses a climbing beam 6 for roof construction, finishing materials are used for the ridgepole 3 and the climbing beam 6, and a ceiling member (roof panel 7) with a decorative finish on the underside 72 is attached onto the climbing beam 6, and roofing is applied onto the ceiling member to form the ceiling of the room A with an open-ceiling space, eliminating the need for finishing work at high altitudes inside the room due to the construction of the framework and roof (ceiling construction).

Description

Application for exception to loss of novelty has been filed

This invention relates particularly to wooden residential buildings with living spaces that have open ceilings.

As is well known, wooden houses (frame construction) are constructed with frameworks (wire materials) such as pillars and beams, and the roof (construction of the roof slope) is generally constructed by erecting the ridgepole and purlins on the rafters that are set into the rafters, then rafters are lined up on the ridgepole and purlins up to the eaves beams, and roof boards (sheathing boards) are laid on the rafters. Also, instead of the combination of purlins and rafters mentioned above, a climbing beam style is also used in which the cross section of the rafters is made larger to support the roof load.

Living spaces are formed by constructing appropriate floor framing (including the second-floor floor) on the wooden axis, and then constructing the walls, floors, and ceilings. In particular, when an open-ceiling structure is used for a living space, the ceiling is formed with a slope that corresponds to the slope of the roof, just like the ceiling of an attic.

Known types of sloping ceilings include those in which the ascending beams are not exposed to the indoor space (Patent Document 1), and those in which the ascending beams and part of the base material are exposed (Patent Documents 1 and 2).

The sloped ceiling also has an insulating structure to save energy in the building, and Patent Document 1 indicates that the sloped ceiling surface is covered with insulating material. Patent Document 2 suggests that it is desirable to provide insulating material in the ceiling construction members themselves.

JP 2002-242325 A, Figures 1 and 3. JP 2014-190030 A, FIG. 2.

By the way, if insulation material is used as a component of the sloped ceiling in a living space, the surface in question (the surface facing the interior space) must be given a decorative finish in the form of wallpaper. Of course, some kind of decorative finish is also required for the exposed surfaces of roof underlayment materials such as ascending beams.

As a result, the construction of a sloped ceiling in an open-ceiling space requires high-altitude work from inside the room, which is more cumbersome than normal ceiling construction work and is not necessarily efficient.

Therefore, this invention proposes a new wooden house that makes it easy to build rooms with high open spaces.

The wooden house construction according to claim 1 of the present invention is a wooden house construction with a climbing beam in the roof construction, in which finishing materials are used for the ridgepole and climbing beam exposed to the living space, and ceiling members with decorative finishes on the undersides are attached to the upper sides of the climbing beams, and roofing is applied to the ceiling members to form a ceiling for a living space with an open ceiling space.

The wooden house construction according to claim 2 of the present invention is constructed by using finishing materials on the purlins in a roof structure that combines a climbing beam and a purlin.

The finishing materials used are, for example, super-planed components for solid wood, or decorative materials with a decorative treatment applied to the surface for composite materials. When the above-mentioned ridgepole, ascending beams, main beams, and ceiling components with a decorative finish on the underside are assembled to construct a roof, a ceiling for a room with an open ceiling space can be constructed without the need for finishing work such as laying wallpaper.

The wooden house building according to claim 3 of the present invention is further constructed by constructing a reinforcing part perpendicular to the beam erected in the interior space, instead of the fire stopper constructed in the corner part of the framework of the horizontal structural surface that creates the open-ceiling space, and the wooden house building according to claim 4 is formed by connecting and fixing the reinforcing beam perpendicular to the beam erected in the interior space and another beam member on the wall side erected perpendicular to the beam with structural plywood.

As a result, when it comes to ensuring the strength of the horizontal structure, there are no diagonally exposed firestops at the corners of the living space (open-ceiling space), and all that is visible is a narrow catwalk-like structural part (reinforcement part) protruding from the wall surface, providing sufficient reinforcement of the horizontal structure without compromising the aesthetics of the room.

The wooden house construction according to claim 5 of the present invention further comprises living rooms and stairs on the second floor or attic that are integrated with the open ceiling space, allowing for easy air circulation throughout the living areas of the house.

The wooden house construction according to claim 6 of the present invention further comprises ceiling members that have a decorative finish on the underside and a sheathing board on the top, and are roof panels that are fitted with materials that perform specific functions such as insulation and heat shielding materials, and the insulation work for the roof is carried out at the same time as the ceiling of the living room is constructed.

As described above, this invention is configured so that when constructing the roof, finishing materials are used for the ascending beams, etc., so that the ceiling of the open-ceiling living space is finished at the same time as the roof construction work, thereby realizing the efficiency of wooden construction.

FIG. Aerial view of the room.

Next, we will explain the embodiment of the present invention. The embodiment shown is an example of a one-story house with an open-ceiling room A and an attic room B, which is basically constructed in exactly the same way as a conventional wooden house.

That is, the framework is constructed by combining pillars 1 and beams 2, rafters are erected on the rafters, ridge beams 3 and purlins 4 are erected, ascending beams 6 are erected between the ridge beams 3 and eaves beams 5, roof panels 7 are laid on the ascending beams 6 and purlins 4, and appropriate roofing (waterproof construction) is performed on the roof panels 7.

In addition, the framework is constructed using appropriate well-known means (fireworks, diagonal braces, structural plywood) to increase the strength of the horizontal and vertical structural components, and the rooms A and attic B are formed as usual by assembling the floor with floor beams 91, floor joists 92, and floorboards 93, constructing the walls with window sashes 94 and wall base 95 covered with wallpaper, and covering the outside of the walls (the outside of the building) with appropriate exterior materials.

This invention is a method for constructing the above-mentioned conventional wooden house, particularly for constructing room A with an open-ceiling space, by specifying the materials to be used for the ridgepole 3, main structure 4, ascending beams 6, and roof panel 7, and by providing a reinforcing section 8 in the framework structure to increase the strength of the horizontal structure.

The ridgepole 3, main structure 4, and ascending beams 6 are made of finished materials such as super-planed components if they are solid wood, or decorative materials with a decorative treatment applied to the surface if they are composite wood.

The roof panel 7 is an appropriate structural component, such as an internal component (insulating material/heat shielding material) 73 between the upper and lower surfaces 71, 72, and the lower surface 72 is a finished component. During the construction, a finished ceiling panel may be used in place of the roof panel 7, and the required roof construction may be carried out on the upper surface of the ceiling panel.

The reinforcing section 8 is installed in the corners of the exposed space (open space) of room A when a fire stop is required for strength design purposes. The reinforcing section 8 is installed along the beam member on the wall side perpendicular to the beam 2 installed in the indoor space in place of a fire stop, and is assembled using truss bars 82 and plywood 83 that are integrated with the reinforcing beam 81 and the beam member on the wall side that is the target of the fire stop for the beam.

Furthermore, attic room B is connected to the open-ceiling space of living room A, and a staircase will also be constructed in that space.

The wooden house building described above uses specified finishing materials to construct the framework, and therefore the upper part of living space A, which has an open ceiling, is finished at the same time as the framework construction work is carried out. This means that the upper part does not require finishing work such as wallpapering, which makes construction more efficient. In particular, when a specified roof panel 7 is used, it is possible to omit cumbersome insulation and heat shielding work on the roof.

The reinforcing section 8 is also only visible as a narrow catwalk-like structure that protrudes slightly from the wall surface above room A in the open-ceiling space, providing sufficient reinforcement to the horizontal structure without compromising the aesthetic look of the room.

In addition, because attic room B (which also applies when the room is built on the second floor) and the stairs to attic room B are constructed within the open space, the entire living space of the house is unified, and there are other advantages such as the ability to centrally control air circulation for heating, cooling, ventilation, etc.
