Description

  The present invention relates to an inner wall structure, and more particularly, is an inner wall structure that constitutes the interior of a building, and uses a composite plate in which metal sheets are laminated on both sides of a synthetic resin sheet, so that construction can be performed more quickly. The present invention relates to an inner wall structure that can be made.

  A composite plate obtained by laminating a synthetic resin sheet and a metal sheet is lightweight and excellent in durability, and is therefore widely used as a building material. For example, in the interior construction of a building, when building an inner wall, the above composite board is used to process it into a wall panel as a part in advance at the factory, and this is carried into the construction site and constructed in a relatively short period of time. can do. And it can construct by what is called dry construction method which inserts said wall panel in the frame material attached to the floor or the ceiling, and fixes it with a screw (refer patent document 1).

  In addition, the structure of the inner wall using the panel as described above is provided with a hook-shaped mounting bracket bent downward on the back surface of the panel as a base material of the wall, and with a hook-shaped receiver opened upward. A hooking type has been proposed in which a panel is arranged by attaching a member (rail) to a wall surface and hooking the mounting bracket on the receiving member. In such a structure, since the panel to which the mounting bracket is attached can be manufactured in advance at the factory, the inner wall can be constructed in an extremely short time (see Patent Document 2).

  By the way, in the construction of the inner wall using the composite plate as described above, there is an advantage that the construction period is relatively short, but if you include even fine accessory parts, you have to prepare many various types of standardized parts. As a result, there is a problem that the construction cost is higher than the conventional local construction, which is all done manually. Therefore, in the construction of the inner wall using the composite plate, it is desired to reduce the number of parts and further shorten the work period.

  On the other hand, since the composite plate is formed in a thin plate shape that is easily elastically deformed, there is a problem that it is difficult to obtain dimensional accuracy in the construction using the composite plate. In other words, positioning is difficult due to bending or warping at the time of mounting, and it is difficult to align the surfaces with adjacent panels, so considerable adjustment and labor are required for finishing adjustment. Although the method of hanging the panel on the wall can shorten the construction period, depending on the rigidity and dimensional accuracy of the panel itself and the mounting accuracy of the wall-side receiving member and panel-side mounting bracket, This is likely to cause shaking and vibration, and a squeak noise may occur along with the shaking.

  The present invention has been made in view of the above circumstances, and the object thereof is a structure of a hook-type inner wall using a composite plate, which can be constructed more easily with a small number of parts, and can be shaken. Another object of the present invention is to provide an inner wall structure that can be constructed with high dimensional accuracy without causing vibration or vibration.

  In order to solve the above-described problems, in the present invention, the composite plate is bent to form a side wall portion, and a wall surface material having increased rigidity is used. The wall material is suspended by fixing the studs to the wall base, horizontally laying metal bars on the upper and lower parts of the studs, and hooking the notches on the side of the wall material to these metal bars. did. And, while arranging the studs with the opening side facing toward the front, and suspending the wall material, the side parts of the wall materials adjacent to each other are overlapped and inserted from the opening side of the stud to the inside of the stud, The tip edge of each part was abutted against the inner surface of the back part of the stud, so that the wall material was prevented from shaking.

  That is, the gist of the present invention is the structure of the inner wall that constitutes the interior of a building, which is composed of a rectangular flat plate composite plate in which metal sheets are laminated on both sides of a synthetic resin sheet, and two parallel sides of the composite plate The wall was formed into a rectangular tube with one side opened and the side wall was fixed to the wall base vertically with the side of the opening facing the front. And a metal bar extending horizontally on the upper and lower sides of the opening side surface of the stud, and the upper and lower sides of the side surface of the wall material are respectively latched at positions corresponding to the metal bars. Notches are provided, and the wall surface material is arranged by hooking the notches of the side surface portions to the metal bars, and the side surface portions are inserted into the interior of the studs from the opening side surfaces of the studs. That it is abutted against the inner surface of the back of the stud. It resides in the inner wall structure to be butterflies.

  According to the inner wall structure of the present invention, it is mainly composed of a wall material made of a composite plate, a stud, and upper and lower metal bars, and a notch provided on a side surface of the wall material is hooked on each metal bar. Since the wall materials are arranged by the above, the number of parts is small, and the construction can be performed very easily in a short period of time. And since it has a structure in which the side surface portion of the wall surface material is inserted into the interior of the stud and is abutted against the inner surface of the back surface of the stud, the wall material can be easily and highly accurately built on the basis of the stud, In addition, it is possible to prevent the wall material from shaking and vibrating.

It is a horizontal sectional view which shows the support structure of the metal bar for wall surface material suspension, and the connection of each member. It is a side view which shows the support structure of the metal bar for wall surface material suspension. It is a side view which shows the adjustment plate which adjusts the notch position of the side part of a wall surface material.

  An embodiment of an inner wall structure according to the present invention will be described with reference to FIGS. The inner wall structure of the present invention is a structure of an inner wall that constitutes the interior of a building. As shown in FIG. 1, a wall surface material 1 made of a composite plate, a stud 2 that supports the wall surface material, and a wall surface material 1 are suspended. The metal bars 3 and 4 are mainly used. The present invention can be applied to a partition wall as well as a wall of a room or a passage as long as the studs 2 can be arranged on a wall base (not shown).

  The composite plate constituting the wall material 1 is formed by laminating metal sheets on both sides of a synthetic resin sheet and is formed in a rectangular flat plate shape. Examples of the composite plate include a composite plate in which metal sheets are laminated on both surfaces of a synthetic resin sheet, that is, a composite plate having a layer structure of metal sheet / resin sheet / metal sheet. As the above metal sheet, a sheet having a thickness of about 0.1 to 1.0 mm made of a metal such as aluminum (including an aluminum alloy), stainless steel, iron, copper, titanium, tin, nickel, etc. An aluminum sheet of about 2 to 0.5 mm is used. The core resin sheet has a thickness of about 0.6 to 5.0 mm made of a thermoplastic resin such as polyolefins such as polyethylene and polypropylene, polyvinyl chloride, polyamide, polycarbonate, polystyrene, polyhydroxyl ether, and vinyl acetate. Is used.

  The metal sheets (aluminum sheet) on both sides are sufficiently adhered to the synthetic resin sheet in advance using an adhesive such as an ethylene-acrylic acid copolymer, an ethylene-vinyl acetate copolymer, or an unsaturated carboxylic acid such as polyethylene. ing. The composite plate as described above is manufactured by superposing aluminum sheets on both surfaces of a melt-extruded synthetic resin sheet and passing the sheet between rotating rolls. As such a composite plate, for example, “Alpolic” (trade name) manufactured by Mitsubishi Plastics, in which aluminum sheets are laminated on both sides of a polyethylene core sheet, is preferable.

  The wall surface material 1 is formed by folding two parallel sides of a composite plate having a square planar shape to the back surface at a substantially right angle, so that the front surface shape is formed into a quadrangle, usually a rectangle, and on both sides in the installed state. A side surface portion 10 is formed as a depth portion. The standard dimensions of the wall surface material 1 in the installed state are as follows: the height of the front part serving as the design surface is 1820 to 2750 mm, the width is 650 to 865 mm, and the width of the bent side part 10 (outside dimension for bending allowance) Is designed to be 50-70 mm.

  In addition, the side part 10 of the wall surface material 1 is a site | part bent from the groove | channel previously provided along two parallel sides of said composite board. In the case of a composite plate in which aluminum sheets are laminated, the groove is formed by cutting a part of the back side aluminum sheet and the polyethylene sheet in factory processing, and in the thin part, the core polyethylene sheet is placed on the design side aluminum sheet. It is a flat U-shaped groove cut into a slightly remaining state.

  As shown in FIG. 1, the stud 2 is a support member for receiving the wall surface material 1 and is formed in a rectangular tube shape with one side surface opened. That is, it is made of a so-called lip groove steel having a substantially U-shaped cross section perpendicular to the longitudinal direction. The length of one side of the cross section perpendicular to the longitudinal direction of the stud 2 is about 30 to 50 mm, and the length of the stud 2 (height in the installed state) is about 1900 to 2850 mm. The above-mentioned stud 2 is fixed to the wall base vertically from the floor to the ceiling with the opening side surface (side surface opening along the length direction) facing the front (inside the room).

  Although not shown in the drawings, examples of the wall substrate include those obtained by attaching various boards made of non-combustible materials and flame retardant materials to the wall substrate bars 81 and 91 (see FIG. 3), such as gypsum boards used in ordinary interiors. . As shown in FIG. 3, the inter-column 2 is fixed to, for example, wall base bars 81 and 91 of a wall base in a state where a metal bar receiver 5 described later is fitted. A plurality of arrangements are arranged according to the wall length to be constructed, and the arrangement pitch is usually set to about 650 to 865 mm.

  As shown in FIG. 1, the metal bars 3 and 4 are installed horizontally on the front side of the stud 2, that is, on the upper side and the lower side of the opening side surface side. As the metal bars 3 and 4, round steel bars having a diameter of 6 to 12 mm are used. The upper metal bar 3 is attached to a position about 100 to 150 mm below the ceiling, and the lower metal bar 4 is attached to a position about 100 to 150 mm above the floor.

  The metal bars 3 and 4 can be welded to the studs 2 or inserted through holes provided in the side faces of the studs 2 to attach them. Is mounted using. That is, as shown in FIGS. 1 and 3, the upper and lower metal bars 3, 4 are supported by the metal bar metal object 5 attached to the stud 2. As shown in FIGS. 2 and 3, the metal bar receiver 5 has a U-shaped notch for supporting a metal bar, with a horizontal cross section formed in a U-shape and upper portions of two opposing sides. The plate-shaped hardware is attached to the stud with the U-shaped opening facing the front side from the back side of the stud 2.

  The metal bar receiving object 5 is configured to be temporarily fixed with an adjusting screw 51 in a long hole 21 (see FIG. 3) provided in advance on the side surface of the stud 2 when adjusting the height of the metal bars 3 and 4. Moreover, when determining the position of the metal bars 3 and 4, it is comprised so that it may fasten with the fixing screw 52 from the inner side to the back surface part of the stud 2. Therefore, when the metal bar metal receiving piece 5 is used, the metal bars 3 and 4 can be easily attached to the studs 2 and the height and level adjustment of the metal bars 3 and 4 can be performed very easily. be able to.

  In the present invention, as shown in FIG. 1, in order to suspend the wall material 1 on the upper and lower metal bars 3, 4, the upper and lower portions of the side surface portion 10 of the wall material 1 have upper and lower portions. Stopping notches 13 and 14 are provided at positions corresponding to the metal bars 3 and 4, respectively. A plurality of the wall materials 1 are arranged by hooking the upper and lower cutouts 13 and 14 of the side surface portion 10 on the upper and lower metal bars 3 and 4, respectively.

  The notch 13 at the top of the side surface portion 10 is provided in advance in a portion corresponding to the side surface portion 10 by punching when the composite plate is formed into a flat plate shape at the factory. As shown in FIG. 3, the cutout 13 is formed in a substantially L shape when viewed from the side in a built-up state, the back corner of its upper end is sealed in a semicircular arc shape, and One is released to the side edge of the side surface 10 (the right edge in FIG. 3). The opening width of the notch 13 is set to such a size that the metal bar 3 can pass relatively loosely.

  Further, the notch 14 in the lower part of the side surface portion 10 of the wall surface material 1 can be processed and provided in the side surface portion 10 in the same manner as the above-described notch 13, but is attached to the side surface portion 10 as shown in FIG. It may be provided on the adjustment plate 6 for adjusting the notch position. As shown in FIG. 4, the adjustment plate 6 is formed by providing a substantially triangular notch 14 in a plate-like body having a rectangular planar shape when the wall surface member 1 is viewed from the side in a state where it is attached to the side surface portion 10. The notch 14 has a shape in which the base of the triangle is released to the long side of the plate-like body and the apex of the triangle is bent upward and arc-shaped and sealed. The adjustment plate 6 is configured to be attached to the side surface portion 10 of the wall surface material 1 by screwing a fixing screw 61 into a long hole (not shown) provided on the back surface and provided in the side surface portion. ing. Therefore, when the adjustment plate 6 is used, as will be described later, the front and rear projecting states of the wall surface material 1 can be easily adjusted by shaking the lower end side of the wall surface material 1.

  By the way, in the structure in which the wall surface materials 1 are arranged, the cutouts 13 and 14 of the side surface portion 10 of the wall surface material 1 are relatively loosely engaged with the metal bars 3 and 4 in order to perform construction easily and quickly. Depending on the accuracy of position adjustment of the metal bars 3 and 4 and the accuracy of bending of the side surface portion 10 of the wall surface material 1, the four notches 13, 13, 14, and 14 of the side surface portion 10 are designed. May not contact the metal bars 3 and 4 evenly. Therefore, in the present invention, in order to prevent the suspended wall surface material 1 from shaking and vibrating, the wall surface material 1 is inserted into the inner surface of the intermediate column from the opening side surface of the intermediate column 2 to the inner surface of the rear surface of the intermediate column. It has been hit. In other words, the wall materials 1 adjacent to each other are inserted into the opening side surface of the intermediate pillar 2 in a state where the side surface portions 10 are overlapped, and are abutted against the inner surface of the inner end of the intermediate pillar.

  In the structure in which the side surface portion 10 is abutted against the inner surface of the back surface portion of the spacer 2, the dimensional relationship between the wall material 1 and the spacer 2, the positional relationship between the metal bars 3 and 4, and the corresponding notches in the side surface 10. The positional relationship between 13 and 14 needs to be designed to satisfy the following relationship. That is, in the present invention, the inner width of the side surface portion 10 of the wall material 1 is (a), the outer width of the side surface of the stud 2 is (b), and from the front side of the stud 2 to the center of the metal bars 3 and 4. When the distance is (c) and the distance from the back surface of the wall material 1 to the center of the metal bars 3 and 4 is (d), the inner normal width (a), the outer normal width (b), and the distance (c). And the distance (d) are set as follows.

  The above relationship is based on the following knowledge. That is, the inner width (a) of the side surface portion 10 of the wall material 1 is larger than the outer width (b) of the side surface of the stud 2 and the inner width (a) and the outer width (b) are the same. If the difference is equal to the distance (c) from the front side of the stud 2 to the center of the metal bars 3 and 4 plus the distance (d) from the back surface of the wall material 1 to the center of the metal bars 3 and 4, The leading edge of the side surface portion 10 of the wall surface material 1 abuts against the back end of the inter-column 2. However, due to the problem of the dimensional accuracy of the member at the time of manufacture, the distortion of the member due to handling, and the mounting accuracy of the spacer 2 and the metal bar bracket 5, it is actually a suspended wall material when designed accurately based on the above relationship Depending on the location, 1 tends to protrude slightly or recede, and there is a tendency that the design surfaces do not line up flatly between the wall surface materials 1.

  Therefore, in the present invention, from the viewpoint of facilitating the construction with a degree of freedom in construction, in other words, by giving a slight margin at the end, in other words, the internal width of the side surface portion 10 of the wall surface material 1 ( By designing a) to be shorter by 0.5 to 1.5 mm, the tip edge of each side surface portion 10 is substantially abutted against the inner surface of the stud 2. Thereby, in the construction which fixes the studs 2 to the wall base first, the wall materials 1 to be suspended can be arranged in a flat state only by aligning the studs 2 vertically and in a straight line.

  Further, in the present invention, in order to prevent minute shaking and vibration of the wall material 1, as shown in FIGS. 2 to 4, the upper and lower metal bars 3 and 4 are provided with the side surface portion 10 of the wall material 1. An anti-slip 7 that can be elastically deformed may be attached to a position corresponding to the notches 13 and 14. Such an anti-slip 7 is composed of a cylindrical molded body made of rubber such as acrylic rubber, nitrile rubber, isoprene rubber, urethane rubber, ethylene propylene rubber rubber, silicon rubber, styrene butadiene rubber, and the like along the center line. A cutting line is provided, which is wound when the metal bars 3 and 4 are installed.

  The construction method of the inner wall structure of the present invention is as follows. In constructing the inner wall, first, the wall material 1 is prepared. The wall surface material 1 is carried into the construction site as a flat plate (composite plate) that has been molded to a predetermined size and grooved. By carrying in with a flat plate, it can be efficiently and easily transported and handled. Then, on the site, two side portions of the flat plate are bent along the groove, and the side surface portion 10 is configured as the wall surface material 1.

  In the construction of the inner wall, first, as shown in FIG. 1, the studs 2 are arranged at a constant pitch on the wall base. At that time, the metal bar receiving object 5 is mounted in advance at the approximate positions where the metal bars 3 and 4 of the studs 2 are installed. As shown in FIG. 3, the metal bar receiver 5 is temporarily fixed with an adjusting screw 51 at first. Then, after adjusting the arrangement and verticality of the studs 2, as shown in FIG. 3, for example, by fixing the studs 2 to the wall base bars 81 and 91 with screws, the studs are extended from the floor 8 to the ceiling 9. 2 is erected.

  Next, as shown in FIGS. 1 to 3, and after adjusting the height and leveling of the metal bars 3 and 4, the fixing screw 52 shown in FIG. Fix it. Thereby, the metal bars 3 and 4 can be installed horizontally in the prescribed position on the front side of the stud 2. Further, an anti-slip 7 is wound in advance at a position where the wall material 1 of the metal bars 3 and 4 is hooked.

  Then, the wall surface material 1 is arrange | positioned at the front side (room inner side) of the stud 2. In the arrangement of the wall surface material 1, first, the adjustment plate 6 is temporarily fixed to the window 11 below the side surface portion 10 of the wall surface material 1. Next, the wall member 1 is suspended by hooking the notch 13 provided in the upper portion of the side surface portion 10 and the notch 14 provided in the adjustment plate 6 to the metal bars 3 and 4, respectively. Then, for the first wall material 1, the verticality is adjusted and the fixing screw 61 is tightened to fix the adjustment plate 6, and then the first wall surface material 1 for the second and subsequent wall materials 1. Using the design surface of the material 1 as a reference, the adjustment plate 6 is fixed by correcting the minute lifting and sinking, that is, performing minute back-and-forth adjustment so that the design surfaces are aligned. After the wall material 1 is suspended, as shown in FIG. 3, a base board 82 and a peripheral edge 92 are provided and finished. Thereby, the inner wall without inclination up and down, right and left, and front and rear can be constructed.
