Description

Application for application of Article 30, Paragraph 2 of the Patent Law is filed October 27, 2021, Catalog "Color the Appearance. Strengthen your building. Published in FIRDOLA FIRDOLA. November 1, 2021, https://www. kmew. co. jp/https://www. kmew. co. jp/shouhin/firdola/ https://www. kmew. co. jp/shouhin/firdola/images/firdola_tec. Published in pdf.

The present invention relates to wall construction. More particularly, it relates to a wall structure comprising panels, furring strips and facings.

Patent Literature 1 describes an exterior wall construction structure that can be easily constructed on an existing wall such as a concrete panel. This exterior wall construction structure is composed of a metal base set in which a metal furring strip is fixed to an existing wall having the ability to hold the exterior wall plate, and a plurality of exterior wall plates fastened to the metal base set. In addition, external corner pillars are fastened to the metal foundation sets at the corners of the existing walls. Corner fasteners are used to fasten the outside corner posts to the metal foundation assembly. The corner fastener has an upper abutting part with a screw hole drilled above the base part, and the screw is inserted into the screw hole and screwed into the metal furrings fixed to the existing wall. This secures the corner fasteners to the metal underlay.

In such an exterior wall construction structure, each metal furring strip is fixed to the existing wall in order to fasten the exterior wall panels and protruding corner posts.

In addition, ceramic and metal sidings are widely used as decorative surface materials, mainly for wooden houses, but in recent years they have also been adopted for general construction. There is also an example of construction on an existing outer wall as a renovation of a building. In this case, the decorative surface material is attached to the base steel material (longitudinal furring strip), but the base steel material is also required for the opening, the external corner, and the internal corner. However, in the existing technology, the deformation of the base steel material or the existing outer wall material that will be the base will occur during an earthquake. It cannot be said that the vibration mechanism and fixing method are sufficient.

When attaching a decorative surface material or the like to an ALC panel or an extruded plate, it is common to attach it via a furring strip or the like instead of attaching it directly by adhesion. ALC panels and extruded plates are often installed vertically, and the standard installation method is the rocking construction method. there is When a panel such as ceramic or metal siding is attached to the ALC panel or extruded plate, it is standard to attach it with a lateral wall. It was common for the edge to flow sideways.

In Patent Document 2, the furring strip is fixed to the center of the panel with a bolt, and the furring strip is moved in the lateral direction (horizontal furring strip) so that the rocking movement is not restricted. It is composed of a structure that inserts a sliding material so that it does not bind.

In addition, in construction methods for renovation (for example, Nichiha MARC system), the attachment is fixed to the ALC panel with an anchor, the furring strip is fixed to the attachment with screws in the vertical direction (longitudinal furring strip), and the ceramic siding is fixed to the furring strip. are doing. In this case, the furring strip is fixed to the ALC panel with anchors, screws and screws. Therefore, there is a possibility that the movement (rocking) of the ALC panel is likely to be restricted.

JP-A-2005-248533 Japanese Patent Application Laid-Open No. 2020-200752

In the construction of the outer wall as described above, it is desired to provide the metal furring strips at the ends of the existing walls such as corners and openings without chipping the existing walls.

Desired.

In addition, the structure in which the furring strips flow in the horizontal direction (horizontal furring strips) as in Patent Document 2 cannot be applied to construction methods such as siding, which are mostly installed horizontally due to the characteristics of the shape. In order to cope with this problem, it is desired that the furring strips can be attached in the vertical direction after making it difficult to restrict the movement of the panel such as rocking.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a wall structure in which furring strips can be easily provided at any desired position and the locking of a plurality of panels is not easily hindered by a plurality of decorative panels and furring strips.

The front of the exterior wall structure 1 is the outdoors of the building, and the rear of the exterior wall structure 1 is the interior. The direction of arrow Y shown in the drawing is the right direction, and the opposite direction of arrow Y is the left direction. The left-right direction is sometimes referred to as the horizontal direction. The direction of arrow Z shown in the drawing is the upward direction, and the opposite direction of arrow Z is the downward direction. The vertical direction is sometimes called the vertical direction.

Panel 2 consists of an ALC panel. An ALC panel is a board made of Autoclaved Lightweight aerated Concrete (lightweight aerated concrete cured with high-temperature, high-pressure steam).
In this embodiment, the panel 2 may not be an ALC panel, but may be a plate made of other material such as an extruded cement plate, a metal panel, or the like.

A plurality of panels 2 are arranged side by side in the vertical and horizontal directions, and the plurality of panels 2 form a base for mounting the finishing material. The short sides 22 of the plurality of panels 2 arranged adjacent to each other in the vertical direction are adjacent to each other. Long sides 21 of a plurality of panels 2 adjacent to each other in the horizontal direction are adjacent to each other. Therefore, a plurality of panels 2 are constructed vertically.

The outer wall structure 1 of this embodiment includes a plurality of decorative surface members 3 . The decorative surface material 3 is formed to have a substantially rectangular surface. In this embodiment, the decorative surface material 3 is formed in a rectangular (horizontally long) shape extending in the left-right direction when viewed from the front (when viewed from the front).

The decorative surface material 3 is made of ceramic siding. Ceramic siding is an exterior wall material that is decorated by forming irregularities on the surface of a base material or by painting. The main raw materials for the base material are cement, silicic raw materials, fibrous raw materials, admixtures, and the like. The decorative surface material 3 does not have to be a ceramic siding as long as it is a finishing material for walls, and may be a plate material formed of other materials such as metal siding.

The plurality of decorative surface materials 3 are arranged side by side in the vertical and horizontal directions, and the plurality of decorative surface materials 3 form the surface of the outer wall. Long sides 31 of a plurality of decorative surface materials 3 arranged adjacent to each other in the vertical direction are adjacent to each other. The short sides 32 of the plurality of decorative surface materials 3 arranged adjacent to each other in the left-right direction are adjacent to each other. Therefore, a plurality of decorative surface materials 3 are constructed horizontally.

The outer wall structure 1 of this embodiment includes a furring strip 4 . The furring strip 4 is provided for applying a plurality of decorative surface materials 3 to the surface side (front) of the plurality of panels 2 . Therefore, a plurality of decorative panels 3 are attached to a plurality of panels 2 via furring strips 4 . In this embodiment, furring strips 4 are provided with a plurality of vertical furring strips 41 . The vertical furring strip 41 has a shape extending in the vertical direction. Longitudinal furring strips 41 can use channel steel 44 . 4A and 4B show a channel steel 44. FIG. Channel steel 44 has a base piece 46 and a pair of side pieces 42 . The side pieces 42 protrude from both side ends of the base piece 46, and the side pieces 42 face each other. An opening 45 is also provided in the channel steel 44 at a position facing the base piece 46 . The channel steel 44 shown in FIG. 4A and the channel steel 44 shown in FIG. 4B have different width dimensions, and can be appropriately used according to the place of use and purpose of use.

The outer wall structure 1 of this embodiment includes a plurality of adapters 6 . The furring strip 4 (longitudinal furring strip 41 ) is attached to the panel 2 with an adapter 6 . 5A-C and 5D-F show the adapter 6. FIG. The adapter 6 is, for example, a metal piece made of metal such as a steel plate, and has a U-shape having a bottom surface functioning as a fixing piece 61 and a guide piece 62 consisting of a pair of side surfaces. The fixed piece 61 is formed in a substantially rectangular shape (for example, rectangular) when viewed from the front. A fixing hole 63 is provided through the fixed piece 61 substantially on the center line thereof in the front-rear direction (thickness direction of the fixed piece 61). The pair of guide pieces 62 extends from a pair of opposite sides (sides) of the fixed piece 61 toward the outside (forward). Each guide piece 62 is formed in a substantially rectangular shape. A connecting hole 64 is formed in each guide piece 62 . Connecting holes (holes) 64 formed in each guide piece 62 are provided to face each other. Each connecting hole 64 penetrates the guide piece 62 in the left-right direction (thickness direction). Each connecting hole 64 is formed as a long hole extending in the vertical direction. Further, the fixing hole 63 and the connecting hole 64 are displaced from each other in the vertical direction so that their positions do not overlap in the vertical direction. A sheet-like waterproof material 66 made of, for example, a waterproof tape 66 is provided on the rear surface (outer side of the bottom surface) of the fixed piece 61 . The adapter 6 shown in FIGS. 5A to C and the adapter 6 shown in FIGS. 5D to F have different width dimensions (interval between the pair of guide pieces 62), and are appropriately used according to the place of use and the purpose of use. be able to. For example, for the narrow channel 44 shown in FIG. 4A, the narrow adapter 6 shown in FIGS. 5A-C is used, and for the wide channel 44 shown in FIG. Use the wide adapter 6 shown in 5D-F. The dimensions and shapes of the furring strip and the adapter are not limited to these. good too. Further, the channel steel 44 in the present invention includes a shape with a lip (so-called C-shaped steel). One adapter 6 can be used for one furring strip 4 in the case of a long length, but by reducing the size and using two or more adapters, the weight can be reduced and construction is easy.

In this embodiment, the panels 2 are lockably attached to the structural frame 5 . The structural skeleton 5 is the skeleton of a building such as a steel-framed structure, a reinforced concrete structure, or a steel-reinforced concrete structure, and includes columns and beams. Being lockable means that when the structural frame 5 is deformed between layers, each panel 2 rotates slightly and follows the in-plane direction.

A known construction method can be used to construct the plurality of panels 2 so that they can be locked. For example, a vertical wall rocking construction method can be used.

Figures 2A-D show a schematic of vertical wall rocking construction. A plurality of panels 2 are attached to the structural frame 5 via ruler angles 51 , lightning plates 52 , flat plates 53 and uke plates 54 . The panel 2 can be locked by slightly rotating the flat plate 53 attached to the panel 2 with respect to the hook plate 54 fixed to the ruler angle 51 . Also, FIG. 3 shows another vertical wall rocking construction method. A plurality of panels 2 are attached to locking portions 59 of the structural frame 5 via set bolts 58 , speed bolts 56 , angle clips 57 and single plates 55 .

In addition, in this embodiment, metal fittings of the vertical wall locking construction method other than the above examples can also be used.

A plurality of vertical furring strips 41 are attached to the surface side of the plurality of panels 2 as described above. The vertical furring strips 41 are attached to one panel 2 one by one. Thus, the plurality of longitudinal furring strips 41 are separated from the other longitudinal furring strips 41 . Thus, the length of the vertical furring strip 41 is equal to or less than the length of the long side 21 of the panel 2, and the vertical furring strip 41 is arranged so as not to straddle the short sides 22 of a plurality of vertically adjacent panels 2. , are attached to each panel 2 . Vertical furring strips 41 adjacent to each other in the vertical direction are positioned substantially on a straight line in the vertical direction in a normal state in which the panel 2 is not locked.

Each longitudinal furring strip 41 is attached to the surface of the panel 2 via an adapter 6 between its upper and lower parts and, if necessary, between them. The adapter 6 is fixed to the surface of the panel 2 by contacting the fixing piece 61 via a sheet-like waterproof material 66 . In this case, as shown in FIG. 6A, a fixing tool (adapter fixing bolt) 65 such as a bolt, an anchor bolt, a speed bolt, a screw, or a nail is inserted through the fixing hole (hole) 63 of the fixing piece 61 to the panel 2. to fix the fixing piece 61 to the surface of the panel 2 . The adapter 6 is provided substantially in the center of the panel 2 in the left-right direction. By arranging the vertical furring strips 41 substantially at the center in the horizontal direction of the panel 2, the vertical movement of the vertical furring strips 41 when the panel 2 is rocked can be minimized. In addition, when bolts are used as the fixtures 65, it is preferable to provide embedded nuts at predetermined positions when the panel 2 is manufactured.

As shown in FIG. 7 , the vertical furring strip 41 is inserted between a pair of guide pieces 62 of the adapter 6 and fixed to the adapter 6 with connectors (furring strip fixing bolts) 7 . A pair of side pieces 42 of the vertical furring strip 41 are provided with mounting holes 43, respectively. The mounting holes 43 provided in each side piece 42 face each other. The mounting hole 43 may be processed and formed at the construction site, or may be formed in advance at a factory or the like. The connector 7 is composed of, for example, a bolt nut or the like. The vertical furring strip 41 is attached to the adapter 6 by inserting the bolt of the connecting member 7 into the connecting hole 64 and the mounting hole 43 and tightening the nut. Here, since the fixing hole 63 and the connecting hole 64 of the adapter 6 are vertically displaced from the central position, it is easy to arrange the connecting tool 7 so as not to interfere with the fixing tool 65 . Although the vertical position of the adapter 6 is not particularly limited, it is preferable that the fixing hole 63 is positioned above the center in the vertical direction so that the adapter 6 is less likely to be turned upside down due to its own weight when fixed. The vertical furring strip 41 attached in this manner has a connecting hole 64 formed in a long hole, so that the connecting tool 7 can be easily inserted, and when a strong force is applied due to the rocking operation of the panel 2, The connector 7 can move within the connecting hole 64 . Therefore, when the panel 2 is locked, the vertical furring strip 41 can be displaced from the adapter 6, and the locking operation of the panel 2 is less likely to be hindered by the decorative surface material 3 and the vertical furring strip 41.例文帳に追加In addition, the connecting hole 64 may be formed to have a hole diameter larger than the outer diameter of the barrel portion of the bolt of the connecting tool 7 instead of being an elongated hole. The vertical furring strip 41 is attached so that the opening 45 side of the channel steel 44 faces the panel 2 side (rear side). As a result, the head of the fixture 65 is accommodated in the opening 45, and even if the vertical furring strip 41 is firmly inserted between the pair of guide pieces 62 of the adapter 6, it becomes an obstacle to the installation of the vertical furring strip 41. Hateful.

8A-C schematically show the movements of the longitudinal furring strip 41 and the adapter 6 during the locking operation of the panel 2. FIG. The adapter 6 fixed to the panel 2 with the adapter fixing bolt 65 rotates clockwise and counterclockwise with respect to the panel 2 around the adapter fixing bolt 65 when the panel 2 is locked. Further, when the panel 2 is locked, the vertical furring strip 41 fixed to the adapter 6 by the furring strip fixing bolt 7 is vertically fixed to the adapter 6 by the furring strip fixing bolt 7 passing through the elongated hole of the connecting hole 64 . slide to. This makes it difficult for the vertical furring strip 41 to interfere with the locking operation of the panel 2 .

9, 10A and B schematically show the movement of the fastener (fastener) 9 and decorative panel 3 during the locking operation of the panel 2. FIG. A plurality of decorative surface materials 3 are attached in front of the vertical furring strip 41 . A fastener (fastener) 9 is used to attach the decorative panel 3 . The fastener 9 is attached to the surface (front surface) of the vertical furring strip 41 . The fastener 9 has an engaging portion (claw) 92 that engages with the real portion 33 of the decorative panel 3 , and is attached to the vertical furring strip 41 in a state where the fastener 9 is engaged with the real portion 33 . When attaching the fastener 9 to the vertical furring strip 41, it is preferable to make the fastener 9 rotatable with respect to the vertical furring strip 41 when the panel 2 is rocked and a strong force is applied. As a result, the fastener 9 can be easily rotated with respect to the vertical furring strip 41 during the locking operation of the panel 2, and the locking operation of the panel 2 is less likely to be hindered by the decorative panel 3 and the vertical furring strip 41.例文帳に追加In this case, it is preferable that the fastener 9 is rotatably attached to the vertical furring strip 41 with a fastener 93 such as a single screw, nail, or screw.

A plurality of decorative panel members 3 are attached to the front of the vertical furring strip 41 via a plurality of fasteners 9. At this time, the real portion 33 of the decorative panel member 3 is slidable to the engaging portion of the fastener 9. It is preferably locked. As a result, the decorative panel 3 can be slid with respect to the fastener 9 during the locking operation of the panel 2, and the locking operation of the panel 2 is less likely to be hindered by the decorative panel 3 and the vertical furring strip 41.例文帳に追加As shown in FIGS. 11A and 11B, the real portion 33 of the decorative surface material 3 is formed over the entire length of the decorative surface material 3 along the long sides 21 of the upper and lower ends of the decorative surface material 3 . Further, the fastener 9 may be a short one as shown in FIG. 6A, or may be a long one as shown in FIG. 6B. The fasteners 95 for long objects are preferably used on high floors where wind pressure resistance is required, and are rotatably attached to each vertical furring strip 41 with a single screw, nail, screw, or the like. preferable.

The decorative surface materials 3 adjacent to each other in the left-right direction are attached to separate fasteners 9 attached side by side in the left-right direction to the front surface of the same vertical furring strip 41 with the ends on the side of the short sides 32 locked. An elastic body 36 is provided between the short sides 32 . A sealing material or the like is exemplified as the elastic body 36 , thereby ensuring waterproofness between the decorative surface materials 3 . The elastic body 36 has such elasticity that it does not expand and contract and break even when the decorative surface material 3 moves due to the rocking motion. The elastic body 36 is supported by a backup member 35 such as a hat-shaped joiner or a one-sided hat-shaped joiner, and arranged in the joint between the short sides 32 of the decorative panel 3 . An elastic body 8 is provided between adjacent panels 2 . The elastic body 8 ensures waterproofness between the panels 2 .

The long side 31 may not be locked to the fastener 9 in some cases. Therefore, in the second embodiment, the upper portions of the vertical furring strips 41 are arranged so as to straddle the short sides 22 of the vertically adjacent panels 2 . In this case, the fastener 9 can be attached to the upper position of the vertical furring strip 41 across the short side 22 of the panel 2, and the joint between the short side 22 of the panel 2 adjacent in the vertical direction and the joint between the short sides 22 of the panel 2 adjacent in the vertical direction Even when the positions of the joints between the long sides 31 of the decorative surface material 3 and the positions of the joints between the long sides 31 of the decorative surface material 3 substantially match in a front view, the long sides 31 of the decorative surface material 3 can be locked by the fasteners 9, and the decorative surface material 3 can be locked. construction is not damaged. The vertical furring strip 41 bridging the short side 22 of the adjacent panel 2 has been described as being longer than the vertical dimension of the panel 2 . Even if it is less than the length, it may straddle the short side 22 of the adjacent panel 2 by shifting upward or downward.
