  By the way, when this type of frame or panel is used as a floor of a soundproof room or the like, since it is placed on the existing floor, it is required not to be warped or twisted. It is required that squeak noises do not occur when walking on the road.

  However, in the structure described in Patent Document 1, friction noise is likely to be generated at the connecting portion between the vertical frame and the horizontal frame. Moreover, although the strength is ensured by attaching the inner wall surface material to one side of the frame, since the front and back are asymmetric, warping and twisting may occur. Furthermore, when this inner wall panel is used for a floor surface, there is a risk of cracking when a load is applied.

  The present invention has been made in view of such circumstances, and uses a frame structure that prevents generation of frictional noise and suppresses warpage, twisting, cracking, and the like, and a floor frame having this frame structure. The purpose is to provide room units.

  The frame structure of the present invention is constructed by connecting a plurality of frame members in the vertical direction and the horizontal direction to form a rectangular frame shape in plan view, and the connecting portion of each frame member is between the opposing surfaces of the two frame members. In addition, a gap is formed in each frame member, and a surface portion of each frame member is notched, and a recess having an opening end on at least the opposing surface of both frame members faces the opening end. Are formed along the connecting direction of the two frame members, and the connecting members are fixed in the recesses across the frame members, the end surface portion of the recess opposite to the opening end, and the connecting member A gap is formed between both end faces.

With such a frame structure, gaps are formed between the frame members in the connecting portion, and between the both end surfaces of the connecting member that connects these frame members and the end surface portion of the half-recessed portion of the frame member. Since the opposing surfaces of each member do not come into contact with each other, generation of frictional noise can be prevented.
In this case, even if the frame members expand or contract due to the influence of heat, humidity, etc., they are absorbed within the gap, so that mutual contact is prevented, and deformation such as warpage and twisting is reliably prevented. can do.
In addition, it can replace with a metal thing as these frames and a connection member, can reduce weight, and can construct | assemble construction work, such as an assembly-type soundproof room.

  In the frame structure of the present invention, the thickness of the connecting member may be the same as or smaller than the depth of the recess.

  Since the connecting member is disposed in the recess formed by cutting out the surface portion of the frame member, the surface of the frame member and the connecting member is faced by setting the thickness of the connecting member within the range of the depth of the recess. Alternatively, the surface of the connecting member can be formed lower than the surface of the frame member. For this reason, a connection member can be formed without making it protrude from the surface of a frame member, and can be arrange | positioned flat on a floor surface. Therefore, the load is not biased and the deformation and cracking can be prevented.

  In the frame structure of the present invention, the frame member may be formed of a prism, and the connecting member may be formed of a strip-shaped plate material along the connecting direction.

  The prismatic frame member and the connecting member made of plate material facilitate the construction of the connecting structure, and the connecting member of the plate material is housed in the recess, so that the structure can be made almost symmetrical as the frame, warping and twisting The occurrence of this can be prevented more reliably.

  In the frame structure of the present invention, face materials for fixing the frame members facing each other at the connecting portions of the frame members are provided on either one of the front and back surfaces along the surfaces of the frame members. Good.

Rather than stacking one face material on the entire frame, the face materials are individually arranged on either the front or back of each connecting part, so these face materials are the minimum necessary for connecting both frame members. It is possible to set a limited area, which makes it difficult for warping and twisting to occur in these face materials themselves, and does not affect each face material, and has a substantially symmetrical structure on the front and back of the frame. And dimensional accuracy can be further improved.
In addition, it is good to provide this face material on the surface on the opposite side to the side in which the connection member is provided.

  The room unit of the present invention includes a floor frame having the above-described frame structure, a floor panel placed on the floor frame, a wall panel standing around the floor panel, and the wall panel And a ceiling panel provided on the top.

  According to the present invention, gaps are formed between the frame members in the connecting portion, and between both end faces of the connecting member and the end face portions of the half-divided recesses of the frame member, so that the opposing surfaces of each member do not contact each other. Therefore, it is possible to prevent the generation of frictional noise, and even if thermal expansion / contraction occurs in each frame member, it is absorbed within the gap, so that mutual contact is prevented, and deformation such as warpage and twisting is prevented. Can be prevented.

It is formed of a system material and is fixed to each other by an adhesive, staple, or the like. The three floor frames 1A and 1B may be connected to each other using bolts or the like by interposing a spacer sheet.
In the case of using a wood-based material, in order to improve the sound insulation by changing the natural frequency of each member, for example, the frame members 11 and 12 are made of laminated material or single-plate laminated material (LVL), and the connecting member 13 or surface The materials 14A and 14B may be formed of different materials such as medium density fiberboard (MDF) obtained by molding wood fibers.
A plurality of anti-vibration rubber pedestals 21 are fixed to the frame members 11 and 12 and the face members 14A and 14B on the bottom side of the floor frames 1A and 1B at appropriate intervals. The shock and vibration can be reduced in the installed state.

The floor frames 1A and 1B configured as described above are placed on the existing floor in a state where three are arranged side by side as described above, and serve as a cushioning material between the floor frames 1A and 1B. The inner vertical frame members 11B of the floor frames 1A and 1B are connected to each other with the spacer sheet 22 interposed therebetween. The connecting operation of the floor frames 1A and 1B is performed before the floor panel 4 is provided and is easy because it is an operation in the state of the frame.
Then, the wall panel 5 is placed on the wide outer vertical frame member 11A and the outer horizontal frame member 12A forming the outer peripheral portion, the floor panel 4 is laid on the inner side, and the ceiling panel 6 is attached. Thus, the soundproof room unit 2 is constructed.

A gap g2 is also formed between both end faces of the connecting member 13 and end faces of the recesses 15 and 16 of the frame members 11 and 12, and the opposing surfaces of the members 11, 12, and 13 are formed by these gaps g1 and g2. Since they do not contact each other, the generation of frictional noise can be prevented.
In this case, since the frame members 11 and 12 and the connecting member 13 are made of a wood-based material, the frame members 11 and 12 may slightly expand and contract by repeated moisture absorption and drying depending on the season and the room environment. Since the expansion and contraction is absorbed within the gap g1, the mutual contact can be prevented, and the occurrence of deformation such as warping or twisting can be surely prevented.

Further, since the thickness T of the connecting member 13 is set slightly smaller than the depth D of the recesses 15 and 16 on the surfaces of the frame members 11 and 12, the surface of the connecting member 13 disposed in the recesses 15 and 16 is used as the frame member. 11 and 12 can be formed lower than the surface. For this reason, the connecting member 13 can be formed without protruding from the surface of the frame members 11 and 12, and can be disposed flat on the existing floor surface. Therefore, the load is not biased and the deformation and cracking can be prevented.
The use of wood-based materials as the frame members 11, 12, the connecting member 13, and the face members 14A, 14B makes it possible to reduce the weight and facilitate the construction work of the assembly type soundproof room unit 2. be able to.

In addition, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
In the embodiment, four horizontal frame members are used in one floor frame and are constructed in the shape of an “eye” in plan view. However, three horizontal frame members are used in the shape of “day” in plan view. You may build it.
Although each frame member is formed in a prismatic shape and the connecting member is formed of a plate material, the frame member and the connecting member may be formed in a columnar shape or the like in addition to those of these shapes.
Moreover, although the example in which the floor frame constitutes a part of the floor of the soundproof room unit has been shown, the floor of the room unit for various purposes other than the soundproof room can be constituted.
