[0008] This embodiment discloses the following features: The first feature is a building material connecting structure for connecting two building materials, comprising: a first piece protruding from one of the two building materials toward the other; a second piece protruding from the other building material toward the first building material and spaced apart from the first piece; and spacing adjustment means connecting the first piece and the second piece and allowing the spacing to be adjusted by rotation (see Figures 1 to 8).

[0009] A second feature is that the spacing adjustment means includes a screw member, which is rotatably inserted into the first piece with its axial movement restricted, and has a screw shaft portion that screws into the second piece, and a rotational operating portion provided on one end of the screw shaft portion (see Figure 5).

[0010] A third feature is that the first piece is provided with a through hole through which the screw shaft is rotatably inserted, the spacing adjustment means comprises the screwing member and a movement restricting member that restricts the axial movement of the screwing member, the screwing member has an annular rotating operating portion on the screw shaft behind the first piece with an outer diameter larger than the through hole, and the movement restricting member is fixed on the screw shaft in front of the first piece and has a shape that prevents it from passing through the through hole (see Figure 5).

[0011] A fourth feature is that the spacing adjustment means comprises a first screw member and a second screw member, each having a rotating operating part on the rear side of the screw shaft. The first screw member is rotatably inserted into the first piece, with the rotating operating part positioned behind the first piece, and the screw shaft is screwed into the second piece in front of the first piece. The second screw member has the rotating operating part positioned behind the first piece, the screw shaft is screwed into the first piece, and is rotatably engaged with the second piece while its forward movement is restricted (see Figure 7).

[0012] As the fifth feature, the front end of the second screwing member abuts against the second piece (see FIG. 7).

[0013] As the sixth feature, among the two building materials, one is a door frame, and the other is a building material arranged at intervals around the door frame (see FIG. 2).

[0014] The seventh feature is a fitting device, which includes the above building material connection structure (see FIG. 1).

[0015] The eighth feature is a building material connection method, which includes a step of adjusting the distance between the first piece and the second piece by a rotation operation on the distance adjusting means (see FIGS. 5 and 7).

[0016] <First Embodiment> Next, a specific embodiment having the above features will be described in detail based on the drawings. In this specification, the "finding direction" means the lateral direction of the frame body 10 (the left - right direction in FIG. 1). Also, the "prospective direction" means the direction of the frame thickness substantially orthogonal to the "finding direction" (the depth direction in FIG. 1). Also, the "inside of the frame" indicates the inside of the frame body 10, and the "outside of the frame" indicates the outside of the frame body 10.

[0017] FIG. 1 shows a fitting device 1 to which a building material connection structure A according to the present invention is applied. The fitting device 1 is a door device including a frame body 10 which is one of the building materials, an opening - closing body 15 that rotates open and closed within the frame body 10, and another building material 20 arranged at intervals around the frame body 10. The frame body 10 which is one of the building materials and the other building material 20 are connected by the building material connection structure A. Each member constituting this fitting device 1 is formed from a metal material (for example, iron, stainless steel, aluminum alloy, etc.) excellent in strength and corrosion resistance.

[0018] The frame 10 is a rectangular door frame with an opening 10a (see Figure 2) in the center, composed of left and right side frame members 11 and 12, an upper frame member 13 connected between the upper ends of these side frame members 11 and 12, and a lower frame member 14 (sometimes called a door sill) connected between the lower ends of the side frame members 11 and 12. These side frame members 11, 12, upper frame member 13, and lower frame member 14 are pre-welded together in a factory or the like to form the frame body 10. This frame body 10 is then transported to the site of the building or other structure where the joinery device 1 will be installed.

[0019] The left side frame member 11 and the right side frame member 12 are members with a roughly C-shaped cross-section, each having openings 11a and 12a on the wall side, as shown in Figure 4, and are formed in an elongated shape extending in the vertical direction. Similarly, the upper frame member 13 is a member with a roughly C-shaped cross-section and an opening 13a on the wall side, and is formed in an elongated shape extending in the left-right direction.

[0020] A base member 17 is fixed to each of the side frame members 11, 12 and the upper frame member 13 so as to straddle the opening on the wall side (see Figures 4 and 5). This base member 17 is a long, rectangular, flat member, and multiple members are provided at intervals along the longitudinal direction for each of the side frame members 11, 12 and the upper frame member 13. Each lower frame member 14 is welded at one end in the longitudinal direction to the inside of the side frame members 11, 12, or the upper frame member 13.

[0021] An opening / closing element 15 is mounted inside the frame 10 so that it can be opened and closed (see Figure 1). The opening / closing body 15, as shown in the illustrated example, is a door that rotates with its tail end pivotally supported on one of the side frame members 12. Reference numeral 16 in the figure indicates a hinge that pivotally supports the opening / closing body 15. This hinge 16 is a flag hinge as shown in the illustrated example, but other types can be used.

[0022] The building material 20 is fixed to the immovable part (for example, the building on which the joinery device 1 is to be installed) by surrounding the frame 10 at intervals. The building material 20 illustrated in Figure 5 integrally includes a core material 21 that supports the wall portion 2 from the inside and a reinforcing member 22 that is fastened and fixed to the inside of the frame of the core material 21.

[0023] The wall section 2 is composed of two boards (for example, gypsum board, plywood, or other paneling materials) spaced apart in the wall thickness direction. The core material 21 is configured in an inverted U-shape when viewed from the front, surrounding the left and right side frame members 11, 12 and the upper frame member 13 between the wall sections 2, 2.

[0024] The building material connecting structure A comprises a first connecting member 31 with a first piece 31a protruding toward the other building material 20, a second connecting member 32 with a second piece 32a protruding toward the first building material (frame 10) from the other building material 20, and a spacing adjustment means 40 that connects the first connecting member 31 and the second connecting member 32 and allows the spacing W between them to be adjusted by rotation (see Figure 5).

[0025] The first connecting member 31 is an angle-shaped member consisting of a flat base portion 31b and a first portion 31a that is substantially perpendicular to the base portion 31b in its cross-section and protrudes toward the second connecting member 32. The base portion 31b is fixed to the base member 17 by welding or the like. The first portion 31a is provided with a through hole 31a1 through which a screw-type member 41, described later, is rotatably inserted. In the illustrated example, this first connecting member 31 is continuous over substantially the entire length in the longitudinal direction of the side frame members 11, 12 or the upper frame member 13. As an alternative example, the first connecting member 31 can be provided on a portion of the side frame members 11, 12 or the upper frame member 13 in the longitudinal direction, or multiple connecting members can be provided at intervals in the longitudinal direction.

[0026] The second connecting member 32 is an angle-shaped member consisting of a flat base portion 32b and a second portion 32a that is substantially perpendicular to the base portion 32b in its cross-section and protrudes toward the first connecting member 31. The base portion 32b is fixed to the reinforcing member 22 by welding or the like. The second portion 32a is provided with a screw hole 32a1 into which a screw-type member 41, described later, is screwed. In the illustrated example, this second connecting member 32 is continuous over substantially the entire length of the reinforcing member 22 in the longitudinal direction. As an alternative example, the second connecting member 32 can be provided on a portion of the reinforcing member 22 in the longitudinal direction, or multiple connecting members can be provided at intervals in the longitudinal direction.

[0027] As shown in Figure 5, the first piece 31a of the first connecting member 31 and the second piece 32a of the second connecting member 32 are arranged side by side with a gap W in the depth direction. The gap W can be adjusted by rotation using the gap adjustment means 40.

[0028] Furthermore, the frame 10, base member 17, and first connecting member 31 described above can be made into a single integrated component, either partially or entirely. Similarly, the core material 21, reinforcing member 22, and second connecting member 32 described above can be made into a single integrated component, either partially or entirely.

[0029] The spacing adjustment means 40 includes a screw-in member 41 and a movement restricting member 42 that restricts the axial movement of the screw-in member 41.

[0030] The screw-fitting member 41 is rotatably inserted into the through hole 31a1 of the first piece 31a while its axial movement is restricted by the movement-restricting member 42, and has a screw shaft portion 41a that screws into the screw hole 32a1 of the second piece 32a, and a rotation operating portion 41b provided at one end of the screw shaft portion 41a (the rear end in the illustrated example).

[0031] The screw shaft portion 41a is formed in a cylindrical shape in the area into which the movement restricting member 42 fits, and a male screw is formed in front of this cylindrical portion. The rotating operating section 41b is located behind the first piece 31a and is formed in an annular shape with an outer diameter larger than the through hole 31a1 of the first piece 31a. The rear end of this rotating operating section 41b is provided with a fitting hole that can be fitted with a tool T such as a hex wrench or screwdriver. In addition, the threaded member 41 in the above configuration can be replaced with, for example, a general screw or bolt.

[0032] The movement restricting member 42 is fixed to the screw shaft portion 41a in front of the first piece portion 31a so as to be immovable in the axial direction, and is shaped so as not to pass through the through hole 31a1. In the illustrated example, the movement restricting member 42 is formed in an annular shape with an outer diameter larger than the through hole 31a1. For example, a general type E retaining ring can be applied to this movement restricting member 42. Furthermore, the movement restricting member 42 only needs to be such that it is impossible to pass through it. Other examples include a square shape, a triangular shape, or other shapes.

[0033] Next, the method of connecting building materials in the above-mentioned building material connecting structure A will be explained in detail. This building material connection method includes a step of adjusting the distance W between the first piece 31a and the second piece 32a by rotating the spacing adjustment means 40.

[0034] The building material 20, which is integrated with the second connecting member 32, is fixed to the opening on the wall side in an inverted U-shape when viewed from the front (see Figure 2).

[0035] The frame 10 is inserted inside the frame of the building material 20. Then, the first piece 31a and the second piece 32a overlap in a front view between the side frame member 11 and the building material 20, between the side frame member 12 and the building material 20, and between the upper frame member 13 and the building material 20.

[0036] Then, the screw-fitting member 41 is inserted into the first piece 31a, and the movement-restricting member 42 is fitted onto the screw-fitting member 41 on the tip side (front side) of the first piece 31a.

[0037] Furthermore, the portion of the screw-in member 41 that is closer to the tip than the movement-restricting member 42 is screwed into the second piece 32a. In this process, increasing the amount the second piece 32a is screwed in narrows the gap W between the first piece 31a and the second piece 32a, causing the frame 10 to move towards the back in the depth direction. Furthermore, reducing the amount the second piece 32a is screwed in widens the gap W, causing the frame 10 to move towards the front in the depth direction.

[0038] The spacing W can be adjusted at two locations, upper and lower, between the side frame member 11 and the building material 20; at two locations, upper and lower, between the side frame member 12 and the building material 20; and at two locations, upper and lower, between the upper frame member 13 and the building material 20.

[0039] Therefore, the above procedure makes it easy to adjust the positional relationship between the two connected building materials. Specifically, it is possible to appropriately adjust the position of the entire frame 10 in the depth direction, or to correct the inclination of the frame 10 with respect to the vertical plane.

[0040] <Second Embodiment> In the above-described joinery device 1, the building material connecting structure A can be replaced with the building material connecting structure B shown in Figures 6 and 7.

[0041] The building material connecting structure B comprises a first connecting member 33 with a first piece 33a protruding toward the other building material 20, a second connecting member 34 with a second piece 34a protruding from the other building material 20 toward the one building material (frame 10), and a spacing adjustment means 50 that connects the first connecting member 33 and the second connecting member 34 and allows the spacing W between them to be adjusted by rotation (see Figure 5).

[0042] The first connecting member 33 is an angle-shaped member consisting of a flat base portion 33b and a first portion 33a that is substantially perpendicular to the base portion 33b in its cross-section and protrudes toward the second connecting member 34, with the base portion 33b fixed to the foundation member 17 by welding or the like. The first piece 33a is provided with a through hole 33a1 through which the first screw-fitting member 51 is rotatably inserted, and a screw hole 33a2 into which the second screw-fitting member 52 is screwed.

[0043] The second connecting member 34 is an angle-shaped member consisting of a flat base portion 34b and a second portion 34a that is substantially perpendicular to the base portion 34b in its cross-section and protrudes toward the first connecting member 33, with the base portion 34b fixed to the reinforcing member 22 by welding or the like. The second connecting member 34 is provided with a screw hole 34a1 into which the first screw-fitting member 51 is screwed.

[0044] The first piece 33a and the second piece 34a are arranged so that they overlap when viewed from the front.

[0045] The spacing adjustment means 50 includes a first screw member 51 having a rotating operating portion 51b on the rear end side of the screw shaft portion 51a, and a second screw member 52 having a rotating operating portion 52b on the rear end side of the screw shaft portion 52a. The first threaded member 51 and the second threaded member 52 may be made of screws, bolts, or the like, similar to the threaded member 41.

[0046] The first screw-type member 51 is rotatably inserted into the first piece 33a, with a rotating operating portion 51b positioned behind the first piece 33a, and the screw shaft portion 51a is screwed into the second piece 34a in front of the first piece 33a.

[0047] The second screw-type member 52 has a rotating operating portion 52b positioned behind the first piece 33a, and the screw shaft portion 52a is screwed into the first piece 33a. The tip (front end) of the screw shaft portion 52a is in contact with the second piece 34a so as to engage with the second piece 34a in a rotatable manner while restricting its forward movement.

[0048] The building material connection method of the building material connection structure B described above includes a step of adjusting the distance between the first piece 33a and the second piece 34a by rotating the spacing adjustment means 50. The following provides a detailed explanation of this building material connection method.

[0049] The frame 10 is inserted inside the frame of the building material 20 such that the first piece 33a and the second piece 34a overlap when viewed from the front.

[0050] The first screw-in member 51 is loosely inserted into the first piece 33a and screwed into the second piece 34a. The second screw-in member 52 is screwed into the first piece 33a and is initially held so as not to come into contact with the second piece 34a. In this state, the distance W between the first piece 33a and the second piece 34a can be adjusted by rotating the first screw member 51. In other words, the front-to-back position of the frame 10 relative to the building material 20 can be adjusted.

[0051] Then, after the adjustment, by tightening the second screw member 52 and bringing it into contact with the second piece 34a, the first piece 33a and the second piece 34a can be fixed in place so that the distance W does not change. Therefore, similar to the building material connection structure A described above, the positional relationship between the two connected building materials (specifically, the frame 10 and the building material 20) can be easily adjusted.

[0052] <Variation> According to the above embodiment, in a particularly preferred example, the building material connecting structure A (or B) is provided at two locations in the direction of the gap extension between the side frame member 11 (or 12) and the building material 20 (up and down direction in Figure 1), and also at two locations in the direction of the gap extension between the upper frame member 13 and the building material 20 (left and right direction in Figure 1). However, other examples include configurations in which the building material connecting structure A (or B) is provided at three or more locations in the gap extension direction, or configurations in which the building material connecting structure A (or B) is provided at only one location in the gap extension direction.

[0053] Furthermore, in the building material connecting structure B shown in Figures 6 and 7, the first screw-in member 51 and the second screw-in member 52 are arranged side by side in the width direction of the gap between the frame 10 and the building material 20 (the left-right direction according to Figure 6). However, as another example of building material connecting structure B, as shown in building material connecting structure B' in Figure 8, the first screw-in member 51 and the second screw-in member 52 may be arranged side by side in the direction of the extension of the gap between the frame 10 and the building material 20 (the up-down direction according to Figure 8) to serve as a spacing adjustment means 50'.

[0054] Further examples include configurations in which the first screw-type member 51 and the second screw-type member 52 are arranged side by side in an oblique direction, or configurations in which one or both of the two types of screw-type members, the first screw-type member 51 and the second screw-type member 52, are made into multiple units.

[0055] Furthermore, according to the above embodiment, first connecting members 31 and 33 having first pieces 31a and 33a are provided on the door / window side, and second connecting members 32 and 34 having second pieces 32a and 34a are provided on the wall side. However, in another example, the relationship may be reversed, with second connecting members 32 and 34 having second pieces 32a and 34a provided on the door / window side, and first connecting members 31 and 33 having first pieces 31a and 33a provided on the wall side.

[0056] Furthermore, in the above embodiment, the first connecting members 31, 33 and the second connecting members 32, 34 are each made up of members with an L-shaped cross-section. However, these first and second connecting members can be any members having the first and second portions, for example, a T-shaped cross-section or other shapes.

[0057] Furthermore, although the above embodiment applies the building material connecting structure A to a door device, the basic structure of this building material connecting structure A can be applied to connecting building materials such as frames to other building materials in sliding door devices, folding door devices, balance door devices, window devices, etc.

[0058] The present invention is not limited to the embodiments described above and can be modified as appropriate without altering the essence of the invention. [Explanation of symbols]
