Description

  The present invention relates to a floor structure and a floor panel in a building such as a wooden house.

  As disclosed in Patent Documents 1 and 2, as a technique for improving the design in the living room space of a wooden house, the ceiling of the lower-floor living room, the upper ceiling surface located above, and the periphery of the upper ceiling surface In some cases, a method of forming a folding ceiling-like ceiling so that the room space can be seen wide as the upper and lower ceiling surfaces of the lower ceiling surface located below the upper ceiling surface is sometimes used. In addition, the beam is actively exposed on the ceiling of the living room and used for design, and the wooden taste and spatial expanse are also felt.

There are three main methods for exposing this type of beam,
1. The ceiling surface is set in the middle of the beam and the lower end of the beam is exposed.
2. Exposing the entire side of the beam and exposing the joists and the back of the floorboard,
3. The beam pitch can be reduced to serve as a joist, exposing the entire side of the beam and the back of the floorboard.

  Of the construction methods for exposing the beam, the construction method 1 is effective in the construction methods 2 and 3 because the exposed portion of the beam is small and lacks a design effect. However, in the case of construction methods 2 and 3, there is no ceiling space between the lower-floor room and the upper-floor room, so there is no storage space for electrical wiring such as ceiling lighting, and there is also a sound insulation effect with the upper-floor room. There is a problem that it cannot be obtained.

  In addition, by exposing the beam, it is necessary to consider the appearance of the beam itself, the aesthetics of the back side of the upper floor material visible from the lower floor room, the joint and other storage, and the cost increase for that purpose. Was inevitable.

  In addition, when the upper and lower ceiling surfaces are used, the upper floor surface is raised to the upper floor room side, so that the height level of the upper floor room rises and the upper floor ceiling height increases. There was also a risk that the internal space would be narrowed due to low.

  The present invention has been made in view of the above problems, and allows the lower floor room to have a spatial extent without reducing the internal space of the upper floor room, and the upper floor. Provided are a floor structure and a floor panel that can be exposed to a ceiling surface of a lower-floor room by using floor beams in a design while ensuring sound insulation with a living room and a storage place for electrical wiring.

  The problem is that a ceiling material is laid on the top surface of the floor beam to form a ceiling surface of the lower floor room, and the entire side surface of the floor beam is exposed to the ceiling surface of the lower floor room, and the upper surface of the ceiling material. This is solved by the floor assembly structure in which the floor material of the upper floor room is laid through joists arranged at appropriate intervals.

  Here, the beam provided around the living room and connected to the pillars at the four corners is particularly referred to as a large beam, and the beam disposed inside the large beam and supporting the floor surface of the upper floor room is referred to as a floor beam. According to the present invention, since the entire side surface of the floor beam can be exposed and disposed on the ceiling surface of the lower floor room, the floor beam can have a sufficient design effect.

  Moreover, the said subject is solved by the floor assembly structure by which the sound-absorbing material was filled and arrange | positioned in the space formed between adjacent joists. Furthermore, in order to solve the above-described problem, in the present floor assembly, an electric cord may be wired in a space formed between adjacent joists. Thereby, high sound insulation with an upper-floor room can be ensured, and electric wiring can be performed between the flooring material of an upper-floor room and the ceiling material of a lower-floor room, and aesthetics can be considered.

  In addition, the above-mentioned problem is that the floor beam exposed on the ceiling surface of the lower-floor room is the ceiling plus the height of the joist and the thickness of the ceiling material, which is provided around the room and joined to the pillar. The problem can also be solved by a floor structure constructed with the ends lowered. That is, according to the present invention, it is possible to form the upper and lower ceiling surfaces without changing the height level of the floor surface of the upper-floor room, so that the space of the lower-floor room can be reduced without narrowing the upper-floor room space. Wide spread can be secured.

  Further, in the floor panel according to the present invention, a plurality of joists are arranged at appropriate intervals inside a frame assembled on four sides, and a ceiling base material is laminated on the lower surface of these frame members and joists, and the upper surface A floor base material and a floor finishing material are laminated to each other. According to the present invention, the above-mentioned floor structure can be made into a panel in a factory in advance and carried into a construction site, and can be easily constructed in a short time.

  According to the floor structure and the floor panel of the present invention, as described above, since it is not involved at all in the formation of the floor surface of the upper-floor room, the lower-floor room space is reduced without affecting the upper floor. It is possible to increase the ceiling height by forming the ceiling surface of the upper and lower levels of the folding ceiling wind on the ceiling of the floor room, and to obtain a spatial spread. In addition, a space for wiring the electrical cord is provided on the ceiling, and the entire side surface of the floor beam is placed on the ceiling surface while ensuring the functionality of providing sound insulation with the sound absorbing material. It can be exposed to enhance the design effect.

  The best mode for carrying out a floor assembly according to the present invention will be described below with reference to the drawings.

  1 to 4 show an embodiment of a floor assembly structure according to the present invention, FIG. 1 is a cross-sectional view of the floor assembly structure viewed from a direction parallel to the floor beam, and FIG. 2 is an orthogonal view of the floor assembly structure to the floor beam. 3 and 4 are sectional views showing a ceiling of a living room adopting the floor assembly structure of the present invention.

  As shown in the drawing, a ceiling material 2 is laid on the top surface of the floor beam 1 to form a ceiling surface of the lower floor room 101. The ceiling material 2 has a structure in which a ceiling base material 21 and a ceiling finishing material 22 are laminated. In the illustrated embodiment, a structural plywood having a thickness of 12 mm is used as the ceiling base material 21. Then, the ceiling material 2 is laid on the top surface of the floor beam 1 in this way, so that the entire side surface of the floor beam 1 is exposed to the ceiling surface of the lower floor room 101.

  On the upper surface of the ceiling material 2, joists 4 are arranged at appropriate intervals. In the illustrated form, the joists 4 are formed with a height of 43 mm and a width of 50 mm, and are arranged at intervals of about 250 mm.

  In addition, the floor beam 1 supporting the ceiling material 2 and the joists 4 adds the thickness of the ceiling material 2 and the height of the joists 4 to the large beams 5 provided around the living room 101 and joined to the pillars. It is installed with the top of the ceiling lowered. That is, in the illustrated embodiment, the floor beam 1 is constructed with the top end lowered by about 60 mm from the large beam 5. The floor beams 1 are installed on the ceiling surface of the living room 101 at intervals of about 1000 mm.

  On the upper surface of the joist 4, the flooring 3 of the upper-floor room 102 is laid. This flooring 3 has a structure in which a floor base material 31 and a floor finishing material 32 are laminated. In the illustrated embodiment, a structural plywood having a thickness of 24 mm is used as the floor base material 31. A floor finish 32 having a thickness of 12 mm is attached to the upper surface of the structural plywood.

  Furthermore, in the floor assembly structure of the present embodiment, the sound absorbing material 6 is filled and disposed in the space formed between the adjacent joists 4 in order to improve the sound insulation between the rooms on the upper and lower floors. In the illustrated form, glass wool having a thickness of 50 mm is used for the sound absorbing material 6.

  Further, in a space formed between the adjacent joists 4, a storage portion 71 for the electric cord 72 is also provided. The storage portion 71 is formed by arranging some joists 4 at intervals of about 30 mm. The storage unit 71 is wired with an electrical cord 72 such as a lighting fixture attached to the ceiling surface of the lower floor room 101. Therefore, the ceiling member 2 below the storage unit 71 is provided with wiring holes 23 for leading the wired electric cord 72 to the ceiling surface at appropriate locations.

  In such a floor structure, a side member 52 is provided on the side of the large beam 5, and a lower ceiling surface member 53 is attached to the lower surface of the large beam 5 to cover the large beam 5. Thereby, the ceiling place 8 is formed in the peripheral part of the ceiling of the lower-floor room 101. The electric cord 72 wired to the storage part 71 is connected to the storage part 71 from outside the living room via the wiring hole 51 provided in the girder 5, the joint elbow 73 attached to the end of the ceiling member 2, and the like. Is drawn into the appropriate wiring hole 23.

  With such a floor assembly structure, the ceiling of the lower-floor room 101 is formed with two upper and lower ceiling surfaces of the folding ceiling wind, and the ceiling height can be partially increased. Since the plurality of floor beams 1 whose entire side surfaces are exposed run in the same direction, the design of the living room 101 can be improved.

  Next, the floor panel according to the present invention will be described. The above-mentioned floor assembly structure can be formed in advance at a factory to form a floor panel 10 by shortening the construction process at the site.

  The floor panel 10 is formed by assembling frames 11 on four sides and arranging a plurality of joists 4 at appropriate intervals inside the frame 11. Then, the floor base material 21 and the ceiling finishing material 22 are laminated on the lower surface of the frame 11 and the joists 4, and the floor base material 31 and the floor finishing material 32 are laminated on the upper surface to form a sandwich structure. . In addition, the floor panel 10 is filled with the sound absorbing material 6 between the adjacent joists 4, and in order to wire the electric cords 72, the storage portions 71 are formed by narrowing the intervals between some joists 4. The

  The floor panel 10 is prepared in two types: a floor panel 10a disposed at the center of the ceiling and a floor panel 10b disposed around the ceiling. The floor panel 10a is formed with a width according to the interval at which the floor beam 1 is installed, both ends are placed on the top surface of the floor beam 1, and are fixed to the floor beam 1 with screws or the like. The floor panel 10 b is formed with a width that matches the distance between the large beam 5 and the floor beam 1 adjacent to the large beam 5. In the floor panel 10b, the end of the floor base material 31 disposed on the girder 5 is arranged in the frame 11 so that the floor base material 31 (and the floor finishing material 32) cover the top surface of the girder 5. It extends from the upper surface and is formed in a joint shape, and is fixed to the girder 5 with nails or screws.

  With the floor panel 10 having such a configuration, not only the design effect and sound insulation performance by the floor assembly structure can be ensured, but also the man-hours at the construction site can be reduced, and the construction period can be shortened. It is also possible.

  When the floor assembly structure of the present invention is formed by the floor panel 10, it is preferable to cover the surface of the ceiling finishing material 22 with a curing sheet or the like at the time of construction. Adhesion can be prevented.

  The floor assembly and floor panel according to the present invention can be suitably used in a living room where the ceiling height is relatively high, such as a living room of a wooden house, and which requires a spatial spread and a high design.
