Description

Technical Field

[0001] The invention disclosed in the present application relates to a joint member for a wall heat insulating material used in a heat insulating method for an outer peripheral portion of a steel frame building, and a wall heat insulating structure using the joint member.

Background Art

[0002] As a wall heat insulating structure adopted for an outer peripheral portion of a steel frame building, an inner wall base panel in which a frame body and a heat insulating material are integrated is built in the plane of the frame structure surrounded by column members and beam members of the outer peripheral portion or on the indoor side of the plane to form a heat insulating line, and an inner wall finishing material such as a plaster board or wallpaper is constructed on the inner wall base panel. Such a structure is known. The frame body of such an inner wall base panel is formed using wood or lightweight steel members, and as the heat insulating material, a board-shaped heat insulating material made of a foamed resin molded body such as polystyrene foam, polyethylene foam, rigid urethane foam, or phenolic foam is frequently used. The applicant of the present application has also proposed, for example, in Patent Documents 1 and 2, a wall heat insulating structure in which such an inner wall base panel is built on the indoor side of the frame structure and has been put into practical use.

[0003] In such a wall heat insulating structure, the inner wall base panel is fixed to column members and beam members constituting the frame structure via metal mounting members. Therefore, even if the inner wall base panel is built in slightly separated from the frame structure, a heat bridge is formed through the mounting member connecting the frame structure and the inner wall base panel, which may become a weakness in heat insulation design. When a lightweight steel member with a high thermal conductivity is used for the frame body constituting the inner wall base panel, this concern becomes particularly significant. In addition, the gap itself formed between the frame structure and the inner wall base panel around the installation location of the mounting member is also likely to be a break in the heat insulating line.

[0004] Therefore, the applicant has commercialized a wall insulation structure in which a board material made of a rigid foamed resin molded body, which has excellent self-supporting properties and easily provides uniform thermal insulation performance, is installed as a wall insulation material on its own within the structural plane of a frame frame without any gaps, and has disclosed this in, for example, Patent Document 3. In this wall insulation structure, the lower and upper edges of the wall insulation material are simply fixed to special fittings attached above the foundation and below the beams, respectively, to hold the wall insulation material upright. In addition, the side edges of adjacent wall insulation materials in the horizontal direction are held together flush with each other using a joint member that is roughly H-shaped in plan view, which has grooves that can clamp the side edges joined back to back. A similar shape of such a joint member that is roughly H-shaped in plan view and interposed at the adjacent locations of board materials is disclosed in, for example, Figure 6(a) of Patent Document 2. [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 10-266417 [Patent Document 2] Japanese Patent Application Publication No. 10-280587 [Patent Document 3] Japanese Patent Publication No. 2023-108965 [Overview of the project] [Problems that the invention aims to solve]

[0006] In the aforementioned wall insulation structure, where board-shaped wall insulation materials are laid adjacent to each other horizontally along the structural plane of the building frame, the wall insulation materials are installed sequentially by first fixing the wall insulation material on the first-installed side, then fitting one side of the roughly H-shaped joint member into its side edge from the side, and then inserting the side edge of the wall insulation material on the second-installed side into the other side of the joint member from the side to position it. In other words, because the order of installation and the direction of insertion of the wall insulation materials and joint members are fixed in one direction, the installation is either clockwise or counterclockwise, making it difficult to insert the last piece into the groove of the roughly H-shaped joint member.

[0007] The invention disclosed herein was conceived in view of the above circumstances, and aims to propose a joint member with excellent workability that can easily hold adjacent wall insulation materials together, regardless of the order of construction, when installing self-supporting wall insulation materials made of foamed resin molded board material or the like adjacent to each other along the structural plane of the building frame, and a wall insulation structure using the joint member. [Means for solving the problem]

[0008] To achieve the aforementioned objective, the present invention discloses a joint member interposed at a location where board-shaped wall insulation materials are installed adjacent to each other, for holding the wall insulation materials flush with each other, and the basic configuration of the joint member comprising: a clamping piece having a depth dimension matching the thickness of the wall insulation material and sandwiched between the side edges of adjacent wall insulation materials; a front fixing portion provided on one side of the clamping piece; a fixed front pressing piece extending out to one side from the front end edge of the clamping piece perpendicular to the clamping piece and facing the front fixing portion; and a movable front pressing piece arranged in substantially the same plane as the fixed front pressing piece and attached so as to be able to move from a position where it does not protrude to the other side of the clamping piece to a position where it protrudes to the other side of the clamping piece.

[0009] In the joint member of the wall insulation material relating to this basic configuration, the pre-fixing portion is preferably composed of a backing piece on the pre-installed side that extends from the rear end edge of the clamping piece perpendicular to the clamping piece and protrudes to one side of the clamping piece.

[0010] Alternatively, the pre-fixing portion may be composed of a puncture piece that protrudes perpendicularly from the clamping piece to one side of the clamping piece from a suitable intermediate position in the depth direction of the clamping piece.

[0011] Furthermore, the joint member of the wall insulation material relating to the basic configuration described above may also include a backing piece on the post-installation side that extends from the rear end edge of the clamping piece perpendicularly to the clamping piece and protrudes to the other side of the clamping piece.

[0012] Furthermore, the joint member of the wall insulation material relating to the basic configuration described above can also be configured such that a portion of the movable surface retaining piece overlaps the fixed surface retaining piece, and the overlapping portion is pivotally attached via a single pin joint, thereby allowing the movable surface retaining piece to rotate in substantially the same plane as the fixed surface retaining piece.

[0013] In this case, it is more preferable that temporary fastening means for fixing the movable front pressing piece in a position that protrudes to the other side of the clamping piece is provided at the point of interference between the movable front pressing piece and the clamping piece or the fixed front pressing piece.

[0014] Furthermore, the wall insulation structure invention disclosed in this application is characterized in that the aforementioned joint member is interposed at the location where board-shaped wall insulation materials are installed adjacent to each other, thereby holding the wall insulation materials flush with each other. [Effects of the Invention]

[0015] By using the joint members configured as described above, when installing board-shaped wall insulation materials made of foamed resin molded bodies adjacent to each other, the adjacent wall insulation materials can be installed from either the left or right, regardless of the order of installation, and can be held in place easily and with precision. This makes it possible to efficiently construct a wall insulation structure with continuous insulation lines without gaps within the structural frame of the outer perimeter of a steel-framed building.

Mode for Carrying Out the Invention

[0017] Fig. 1 shows an outline of a wall heat insulating structure applied to an outer peripheral portion of a steel frame building. This wall heat insulating structure forms a heat insulating line between the building frame 1 and the inner wall base 31 by building a board-shaped wall heat insulating material 2 inwardly of the building frame 1 surrounded by a column member (not shown) and a beam member 11 in the outer peripheral portion. In Fig. 1, reference numeral 4 denotes an outer wall material, reference numeral 5 denotes a foundation, reference numeral 12 denotes a panel frame assembled within the plane of the building frame 1, reference numeral 32 denotes a floor member of the first floor, reference numeral 33 denotes a ceiling member of the first floor, and reference numeral 34 denotes a floor member of the second floor. And the "board-shaped wall heat insulating material" in this invention is assumed to be a flat plate-shaped molded product having a thickness of several cm to a dozen or so cm made of a foamed resin such as polystyrene foam, polyethylene foam, rigid urethane foam, or phenol foam, and having rigidity enough to stand by itself (not deformed irregularly).

[0018] The wall heat insulating material 2 is built in substantially over the entire lower dimension of the beam on each floor. In the first floor portion of the exemplary embodiment, the lower edge portion of the wall heat insulating material 2 is fixed at a position where it abuts or is close to the top end of the foundation 5 through appropriate mounting means, and the upper edge portion of the wall heat insulating material 2 is fixed at a position where it abuts or is close to the lower surface of the beam member 11 through appropriate mounting means. In the invention disclosed in the present application, the detailed fit of the mating portions of the foundation 5, the beam member 11, and the wall heat insulating material 2 is not particularly limited.

[0019] The main part of the invention disclosed in this application lies in the joint member interposed at the location where a plurality of wall heat insulating materials 2 are built adjacent to each other in the lateral direction (the direction perpendicular to the plane in FIG. 1). One embodiment of the joint member is shown in FIGS. 2 to 3, and its usage mode is shown in FIGS. 4 to 5. In the following, when explaining the positional relationship of each part of the joint member and the direction of movement, the viewpoint of FIG. 4(a) (the viewpoint facing the indoor surface of the wall heat insulating material 2) when viewing the joint member 6 interposed at the adjacent location of the wall heat insulating material 2 from the indoor side is used as a reference to specify the depth direction (front-back direction, front-rear direction), lateral direction (left-right direction), and height direction (up-down direction).

[0020] The exemplified joint member 6 includes a sandwiching piece 61 sandwiched between the side edge portions of the wall heat insulating materials 2 adjacent to each other, a backrest piece 62 on the side of the first construction side that projects from the rear edge (the outdoor edge) of the sandwiching piece 61 orthogonally to the sandwiching piece 61 and projects to one side of the sandwiching piece 61, a backrest piece 63 on the side of the later construction side that projects from the rear edge (the outdoor edge) of the sandwiching piece 61 orthogonally to the sandwiching piece 61 and projects to the other side of the sandwiching piece 61, a fixed front pressing piece 64 that projects to one side from the front edge (the indoor edge) of the sandwiching piece 61 orthogonally to the sandwiching piece 61 so as to face the backrest piece 62 on the side of the first construction side, and a movable front pressing piece 65 that is arranged in substantially the same plane as the fixed front pressing piece 64 and is attached so as to be able to move from a position that does not protrude to the other side of the sandwiching piece 61 to a position that protrudes to the other side of the sandwiching piece 61.

[0021] The exemplified joint member 6 is integrally processed by cutting and bending a thin steel plate or an aluminum plate for each of its parts, and the plate thickness of each part is the same (about 0.5 mm to 1.0 mm). However, as the material of the joint member 6, instead of a metal plate with a high thermal conductivity, a hard synthetic resin with a low thermal conductivity, hard processed paper (fiber board), etc. can also be adopted. In that case, the plate thickness of each part does not have to be the same.

[0022] The sandwiching piece 61 has a substantially long rectangular flat thin plate shape, and its depth dimension (the short side dimension in the exemplified form) is formed to match the plate thickness of the wall heat insulating material 2. The plate thicknesses of the wall heat insulating materials 2 adjacent to each other are basically the same size.

[0023] In the exemplary configuration, the backing piece 62 on the pre-installed side is approximately square in front view and protrudes to one side (the left side in Figure 4(a)) from the upper half of the clamping piece 61. This pre-installed backing piece 62 constitutes the "pre-fixing portion provided on one side of the clamping piece" as described in the claims. On the other hand, in the exemplary configuration, the backing piece 63 on the later-installed side is approximately square in front view, similar to the backing piece 62 on the pre-installed side, and protrudes to the other side (the right side in Figure 4(a)) from the lower half of the clamping piece 61, and is positioned on the same plane as the backing piece 62 on the pre-installed side. However, the front shape of both backing pieces 62 and 63, and the dimensions of their protrusions to the left and right, respectively, do not necessarily have to be the same, and the position of the protrusions in the vertical direction is not particularly limited.

[0024] In the example configuration, the fixed front retaining piece 64 is approximately square in shape and the same size as the backing piece 62 on the previously installed side. It protrudes to one side from the upper half of the clamping piece 61 and is positioned to overlap with the backing piece 62 on the previously installed side when viewed from the front. The distance between the fixed front retaining piece 64 and the backing piece 62 on the previously installed side is set to match the thickness of the wall insulation material 2. Note that the front shape and dimensions of this fixed front retaining piece 64 do not need to be identical to those of the opposing backing piece 62 on the previously installed side.

[0025] In the example configuration, the movable front retaining piece 65 is approximately square in shape and slightly larger than the fixed front retaining piece 64. One corner of the movable front retaining piece 65 overlaps with the corner of the fixed front retaining piece 64 closest to the clamping piece 61 (the lower right corner in the example configuration), and the overlapping portion is pivotally attached via a pin joint 66. For example, a pop rivet (blind rivet) can be used for this pin joint 66. As a result, the movable front retaining piece 65 is held so that it can rotate around the pin joint 66 in approximately the same plane as the fixed front retaining piece 64 with appropriate frictional resistance. Here, the expression "approximately" in the same plane is used to mean that there is a step (plane misalignment) of one plate thickness between the fixed front retaining piece 64 and the movable front retaining piece 65.

[0026] The rotation range of the movable front retaining piece 65 is set to include a position in which it does not extend beyond the clamping piece 61 to the other side (right side) and, in a front view, completely opens the backing piece 63 on the post-installation side (this is called the "open position"), and a position in which it extends beyond the clamping piece 61 to the other side and overlaps the backing piece 63 on the post-installation side in a front view (this is called the "opposing position"). In the example configuration, in the front view of Figure 4(a), the state in which the movable front retaining piece 65 is to the lower left of the pin joint 66 is the open position, and the state in which it is to the lower right of the pin joint 66 is the opposing position, and it rotates approximately 90 degrees between these two positions. However, there is no particular inconvenience even if the movable front retaining piece 65 rotates beyond 90 degrees, and in the example configuration, it is possible to rotate 360 ​​degrees.

[0027] When the movable front retaining piece 65 is in the opposing position, it is desirable that the distance between it and the backing piece 63 on the later-installed side matches the thickness of the wall insulation material 2, similar to the fixed front retaining piece 64 described above. Therefore, this joint member 6 employs a correction means to compensate for a dimensional difference equivalent to one sheet of sheet thickness. Specifically, the area near the diagonal position with the pin node 66 of the movable front retaining piece 65 is pushed out to the back side by about one sheet of sheet thickness to form a hemispherical bulge 67, and the distance between the back top surface of this bulge 67 and the backing piece 63 on the later-installed side matches the thickness of the wall insulation material 2. Note that multiple such bulges may be formed.

[0028] Other corrective means to replace the stamping deformation include, for example, bending the middle part of the movable front pressing piece 65 in a mountain-valley shape by the thickness of one sheet of metal so that a part of it is in the same plane as the fixed front pressing piece 64, or attaching a sheet of metal of the same thickness to an appropriate place on the back surface of the movable front pressing piece 65.

[0029] Furthermore, after the wall insulation material 2 is installed using this joint member 6, it is desirable that the movable front retaining piece 65 be held in place so that it does not easily move from its opposing position. Therefore, the joint member 6 is also provided with a temporary fixing means for holding the movable front retaining piece 65 in the opposing position. In the exemplary embodiment, the portion of the movable front retaining piece 65 that interferes with the front end edge of the clamping piece 61 in the opposing position is punched out on the back side by about the thickness of one plate to form a hemispherical projection 68, and the back top surface of the projection 68 is pressed against the front end edge of the clamping piece 61 to make it difficult to rotate.

[0030] Furthermore, instead of the extrusion deformation shown in the example, this temporary fastening means may be modified by, for example, cutting and raising a claw on the back side of the movable front retaining piece 65 and hooking it onto the front edge of the clamping piece 61, or by forming a projection on the front edge of the clamping piece 61 and hooking it onto the lower edge of the movable front retaining piece 65 in the opposite position. Also, if the movable front retaining piece 65 can be held in the open position by a similar temporary fastening means, the workability when installing the wall insulation material 2B on the later-installed side in the installation procedure described later will be improved.

[0031] Figure 5 shows the procedure for installing the wall insulation material 2 using the joint member 6 configured in this way. First, the lower and upper edges of the wall insulation material 2A on the pre-installed side are fixed to the foundation 5 and beam member 11, respectively, by appropriate means. Then, the groove formed by the backing piece 62, clamping piece 61, and fixed front pressing piece 64 of the joint member 6 on the pre-installed side is fitted from the side of the wall insulation material 2A to an appropriate intermediate position in the height direction of its side edge. Next, the wall insulation material 2B on the later-installed side is installed while supporting the movable front pressing piece 65 in the open position. At this time, since the entire backing piece 63 on the later-installed side is open to the front, the wall insulation material 2B on the later-installed side can be brought adjacent to the wall insulation material 2A on the pre-installed side by pushing it in from the front, rather than from the side as in the conventional method. Once the wall insulation material 2B on the later-installed side is in contact with the backing piece 63 on the later-installed side and positioned, the movable front pressing piece 65 is rotated to the opposite position to press down on the surface of the wall insulation material 2B on the later-installed side, and the lower and upper edges of the wall insulation material 2B are then fixed to the foundation 5 and beam member 11, respectively, by appropriate means. In this way, the surfaces of adjacent wall insulation materials 2A and 2B can be installed with precision. In areas where adjacent wall insulation materials 2A and 2B are to be installed in reverse order from left to right, the joint member 6 can be used in a state where it is rotated 180 degrees in a front view.

[0032] Figure 6 is a perspective view showing another embodiment of the joint member. Parts that have the same function or operation as those in the previously described embodiment are denoted by the same reference numerals. This joint member 60 is formed such that the depth dimension of the clamping piece 61 is slightly smaller than the thickness of the wall insulation material 2. Instead of the backing piece 62 on the pre-installed side in the previously described embodiment, it is equipped with a puncture piece 69 that protrudes from the clamping piece 61 perpendicularly to one side. The puncture piece 69 is positioned set back from the front edge of the clamping piece 61 by about 1 / 2 to 2 / 3 of the thickness of the wall insulation material 2 in the depth direction. In the exemplary embodiment, two notches extending in the depth direction are formed near the top and bottom of the clamping piece 61, and the upper and lower portions are bent to one side. The puncture piece 69 is formed to have a roughly triangular front shape with its tip sharply pointed, and is inserted into the side edge of the wall insulation material 2. This puncture piece 69 constitutes the "pre-fixing portion provided on one side of the clamping piece" as described in the claims.

[0033] Furthermore, the movable front retaining piece 65 in this joint member 60 differs slightly in its front shape from that of the previously described embodiment, and the position of the pin node 66 is also positioned higher than in the previously described embodiment, but the basic structure, function, and manner of rotation are the same as in the previously described embodiment.

[0034] Furthermore, this joint member 60 does not have the backing piece 63 on the post-construction side as in the embodiment described above. This joint member 60 is used in areas where the wall insulation material 2 is erected in a way that prevents it from falling backward, such as by contacting an appropriate support member 13 located at the rear (outdoor side). Examples of such support members 13 include studs, furring strips, and braces installed within the structural plane of the building frame.

[0035] In this case, the wall insulation material 2A on the first-installed side is erected in the designated position and fixed by appropriate means. Then, while aligning the fixed surface pressing piece 64 of the joint member 60 along the surface of the wall insulation material 2A, the puncture piece 69 is inserted into an appropriate location in the middle of the height direction of the side edge of the wall insulation material 2A and fixed. The puncture piece 69 has an appropriate visible dimension in the vertical direction and is formed to be parallel to the fixed surface pressing piece 64, so when the puncture piece 69 is inserted into the side edge of the wall insulation material 2A, its movement in the front-to-back direction is restrained. Next, while supporting the movable surface pressing piece 65 in the open position, the wall insulation material 2B on the second-installed side is erected adjacent to it. Since this second-installed wall insulation material 2B is erected in a state where it does not fall backward, by rotating the movable surface pressing piece 65 to press the surface of the second-installed wall insulation material 2B, the surfaces of the adjacent wall insulation materials 2A and 2B can be made flush. The position, number, and frontal shape of the puncture fragments 69 can be changed as appropriate.

[0036] As described above, by using the joint member of the invention disclosed herein, a wall insulation structure with seamlessly continuous insulation lines can be efficiently constructed within the structural plane of the outer perimeter frame of a steel-framed building. It is efficient because tape or adhesive is not required when temporarily fixing adjacent wall insulation materials together (tape may be used to seal them after installation to ensure airtightness), and a certain level of construction accuracy can be ensured regardless of the worker's skill. Furthermore, even if the structural frame deforms due to earthquakes or vibrations, the wall insulation material can maintain its self-supporting state without being affected. This joint member can be used not only for plates made of foamed resin material, but also for areas where sound-absorbing materials, fire-resistant coatings, interior base materials, etc., formed in a similar board or panel shape are to be installed continuously.

[0037] The technical scope of the invention disclosed herein should not be interpreted restrictively by the exemplary embodiments, but rather conceptually based on the claims. The example of the insulation structure for a steel-framed building is merely an example, and when implementing the invention disclosed herein, the detailed shape, dimensions, structure, material, quantity, combination with other elements, relative positional relationships, etc., of components not specifically identified in the claims can be modified as appropriate, within a range that yields substantially equivalent or better effects than those of the exemplary form.
