Description

The present invention relates to a panel and a method for constructing the panel.

Conventionally, when fixing a board material that will become a wall surface to the side surface of a column, for example, after fixing a plurality of elongated base materials, the board material is fixed thereon (see Patent Document 1). In addition, runner materials (insert materials) with a U-shaped cross section are fixed to the floor and ceiling surfaces so that the openings face each other in the vertical direction, and the base material is inserted and fixed between the pair of runner materials. After that, the board material was fixed on top of the base material.

Japanese Patent Application Publication No. 2003-64804

However, in the conventional method, each base material is fixed to a column after being aligned in the vertical direction, which requires time for construction. That is, it is necessary to perform positioning multiple times depending on the number of base materials, which requires time and effort. In addition, it was necessary to position each runner material, which was time-consuming.

Therefore, an object of the present invention is to provide a panel and a method for constructing the panel that do not require base material or runner material and can be easily constructed.

As a means for solving the above problems, the present invention provides a panel that covers the surface of a pillar or a wall, comprising: a plate-shaped board material; a cushion layer formed on one side of the board material and having cushioning properties; This is a panel characterized by comprising:

According to such a configuration, by arranging the cushion layer on the surface side of the pillar or wall, even if the surface of the pillar or wall is uneven, the cushion layer can be deformed to correspond to the unevenness. In other words, by positioning the board material (panel) in the vertical direction while deforming the cushion layer to correspond to the unevenness of the surface of the pillar or wall, the surface of the pillar or wall can be adjusted while arranging the panel vertically. can be covered.

In other words, a pillar or wall can be covered with a panel by just one vertical positioning of the panel. In this way, the base material and runner material are not required, and the construction of the panel becomes easy and the construction time can be shortened.

Moreover, it is good also as a structure provided with the protrusion part which protrudes from the said board material in the perpendicular direction, and whose protrusion length is adjustable.

According to such a configuration, after the panel is fixed to the surface of a pillar or wall, the protrusion length of the protrusion is adjusted so that the panel comes into contact with the floor or ceiling in the vertical direction. Supported/abutted on the ceiling surface. This makes it difficult for the panel to shift later.

Further, the cushion layer may be made of a cushion board having cushioning properties, and may include hardware that fixes the cushion board to the board material and connects adjacent panels.

According to such a configuration, the cushion board can be fixed to the board material using the hardware, and adjacent panels can be connected to each other.

Moreover, as a means for solving the above-mentioned problem, the present invention is a method for constructing panels, which is characterized in that a pillar is surrounded by a plurality of the panels, and adjacent panels are connected to each other.

According to such a configuration, by surrounding the pillar with a plurality of panels and connecting adjacent panels, it becomes difficult for the plurality of panels to shift relative to the pillar.

According to the present invention, it is possible to provide a panel that does not require a base material and a runner material and can be easily constructed, and a method for constructing the panel.

It is a rear view of the 1st metal fittings and the 2nd metal fittings concerning this embodiment, and shows an unconnected state (state before insertion).

One embodiment of the present invention will be described with reference to FIGS. 1 to 5. In addition, in FIG. 2, the first hardware 30 and the second hardware 40 are omitted. Furthermore, in FIGS. 3 and 4, for clarity, gaps are formed between the board material 10, the cushion board 20, and the first hardware 30 and second hardware 40.

≪Panel configuration≫
As shown in FIG. 1, the panel 1 (1A to 1D) is a building material that covers the four side surfaces 101 (surfaces) of a square pillar 100 (see FIG. 2), and has a plate-like two-layer structure. It is. The panel 1 includes a board material 10 arranged on the indoor side (outside side), a layered cushion board 20 (cushion layer) fixed to the back surface 11 (one surface) which is a pillar side of the board material 10, and a first hardware 30. , a second hardware 40, two bolts 50 (projections), and two bolts 60 (projections). That is, the cushion board 20 is formed on the back surface 11 side (one surface side) of the board material 10. The front panel 1A and the rear panel 1C, and the left panel 1B and right panel 1D have the same structure. The thicknesses of the board material 10 and the cushion board 20 are, for example, 30 mm.

<Board material>
The board material 10 is a thin plate-like member disposed on the indoor side, and is made of, for example, a wooden board, a noncombustible board (a gypsum board, a calcium silicate board, etc.). Alternatively, a flame-retardant cloth material (fibrous material) may be attached to the surface of the board material 10 to provide fire resistance.

Two bolt holes 13, 13 are formed in the lower part of the board material 10, which are perforated vertically upward from the lower surface 12. The two bolt holes 13 are generally evenly arranged in the width direction of the board material 10. The bolt hole 13 is a female threaded hole into which the bolt 50 is screwed.

Two bolt holes 15, 15 are formed in the upper part of the board material 10, which are perforated vertically downward from the upper surface 14. The bolt hole 15 is a female threaded hole into which a bolt 60 is screwed.

<Cushion board>
The cushion board 20 is a thin plate-like member having cushioning properties, that is, an elastically deformable thin plate-like member. The cushion board 20 is formed of, for example, a synthetic resin layer and a synthetic rubber layer (urethane layer, etc.). In addition, the cushion board 20 is formed of a layer of artificial mineral fibers (rock wool, glass wool, etc.). That is, the cushion board 20 is formed from an appropriate material selected based on required performance (cushioning properties, heat insulation properties, fire resistance, etc.), construction location, and the like.

<First hardware, second hardware>
The first hardware 30 is a member for fixing the cushion board 20 to the board material 10 in the front panel 1A and the rear panel 1C (see FIGS. 2 to 5). The second hardware 40 is a member for fixing the cushion board 20 to the board material 10 in the left panel 1B and the right panel 1D (see FIGS. 2 to 5). Further, the first hardware 30 and the second hardware 40 are connected to each other by inserting the first hardware 30 into the second hardware 40, and as a result, the panels 1A, 1B, 1C, and 1D adjacent in the circumferential direction are connected to each other by inserting the first hardware 30 into the second hardware 40. This is a connecting member (see FIGS. 3 to 5).

A plurality of first metal fittings 30 are fixed to the inner surface of the front panel 1A (the surface facing the column 100, see FIGS. 2 to 5) at predetermined intervals in the height direction (vertical direction). Further, the first hardware 30 is fixed to the inner surface of the front panel 1A (the surface facing the pillar 100) at both ends in the left-right direction. Note that the first hardware 30 is similarly fixed to the inner surface of the rear panel 1C.

A plurality of second hardware 40 are fixed to the inner surface (the surface on the column 100 side, see FIGS. 2 to 5) of the left panel 1B at predetermined intervals in the height direction (vertical direction). Further, the second hardware 40 is fixed to the inner surface (the surface on the column 100 side) of the left panel 1B at both ends in the front-rear direction. Note that the second hardware 40 is similarly fixed to the inner surface of the right panel 1D.

Here, the first hardware 30 on the left side of the front panel 1A and the second hardware 40 on the front side of the left panel 1B will be specifically described.

<First hardware>
The first hardware 30 is a metal member, and is manufactured by bending an elongated metal (iron or the like) plate material. The first hardware 30 includes a base 31 fixed to the board material 10, a leg portion 32 extending from the outer end of the base 31 in the width direction toward the rear side (column 100 side), and a right side (from the rear end of the leg portion 32 to the right side). A stepped portion 33 extending toward the inner side in the width direction, and an inserted portion 34 extending toward the rear side from the right end of the stepped portion 33. That is, the leg portion 32 and the inserted portion 34 are arranged at different levels in the left-right direction.

The base 31 is formed with an insertion hole 31a into which a screw (not shown) is inserted. The base 31 is fixed to the back surface 11 (the surface on the column 100 side) of the board material 10 with screws (not shown). Thereby, when the panel 1A is disassembled, the board material 10 and the first hardware 30 can be easily disassembled (separated), and the first hardware 30 can be easily reused. Note that the base 31 may be fixed to the board material 10 with an adhesive.

Between the base 31 and the leg portion 32, an L-shaped rib 31b that bulges inward is formed by pressing the bent portion from the outside. Thereby, the leg portion 32 is held at a predetermined angle (for example, 90°) with respect to the base 31. Therefore, the front panel 1A and the left panel 1B are held at a predetermined angle.

As described above, the leg portion 32 is disposed one step to the left outside of the inserted portion 34. When the first hardware 30 and the second hardware 40 are assembled (see FIG. 3), the left surface (outer surface) of the leg 32 and the left surface (outer surface) of the base 41 of the second hardware 40 are flush with each other. is configured to be. That is, no gap is formed between the leg portion 32 and the board material 10 constituting the left panel 1B, and the front end portion of the board material 10 is supported by the leg portion 32 from the back side (back side). As a result, even if the front end of the board material 10 constituting the left panel 1B is pushed from the indoor side toward the pillar 100 side (back side), it is well supported by the leg portions 32, and the board material 10 is free from cracks. is becoming less likely to occur.

The inserted portion 34 is a portion of the second hardware 40 that is inserted into an insertion groove 44 to be described later. In this way, by inserting the inserted part 34 into the insertion groove 44, the first hardware 30 and the second hardware 40 are connected, and as a result, the front panel 1A and the left panel 1B are connected. It is now possible to do so.

The thickness of the inserted portion 34 is approximately the same as or slightly smaller than the groove width of the insertion groove 44, and the inserted portion 34 is press-fitted into the insertion groove 44. This increases the frictional force between the inserted part 34 and the base 41 and the holding part 43, making it difficult for the inserted part 34 to come out from the insertion groove 44.

A locking piece 34a formed by cutting and raising is formed slightly on the leading end side (rear side) of the inserted portion 34. The locking piece 34a is a portion formed by punching out the inserted portion 34 in a U-shape and then bending it to the right. The locking piece 34a locks into the locking hole 43c when the inserted portion 34 is inserted into the insertion groove 44, and the inserted portion 34 is difficult to fall out of the insertion groove 44.

The cushion board 20 is arranged on the rear side of the base 31, and the left end portion of the cushion board 20 is fixed to the base 31 with a pin 70. The pin 70 is an accessory (part) of the first hardware 30, and includes a pin body 71 that penetrates the cushion board 20, and a disc-shaped pressing plate 72 that is fixed to the pin body 71 and presses the cushion board 20. It is equipped with. The pin body 71 is made of a conductive material (copper alloy, etc.), and the front end of the pin body 71 is welded to the base 31 by applying electricity with a pin welding machine (not shown). . Alternatively, the first hardware 30 may include a U-shaped holding portion into which the left end of the cushion board 20 is inserted and which holds the left end.

<Second hardware>
The second hardware 40 is a metal member, and is manufactured by bending an elongated metal plate. The second hardware 40 includes a base 41 fixed to the board material 10, a leg portion 42 extending inward from the inner end of the base 41 in the width direction (toward the column 100), and a holding portion extending frontward from the inner end of the leg portion 42. It is equipped with 43 and.

The base 41 is formed with an insertion hole 41a into which a screw (not shown) is inserted. The base 41 is fixed to the back surface 11 (the surface on the pillar 100 side) of the board material 10 with screws (not shown). Thereby, when the panel 1B is disassembled, the board material 10 and the second hardware 40 are easily disassembled (separated), and the second hardware 40 can be easily reused. Note that the base 41 may be fixed to the board material 10 with an adhesive.

The base 41, the leg portions 42, and the holding portion 43 have a U-shape as a whole when viewed from above, and an insertion groove 44 is formed inside thereof. The insertion groove 44 is a groove into which the inserted portion 34 is inserted.

The holding part 43 is a part that holds the inserted part 34 by the base 41 and the leg part 42. The front end side of the holding portion 43 is slightly bent toward the column 100 (inward) to form a slope portion 43a. As a result, the groove width of the insertion groove 44 gradually increases toward the front opening side, so that the inserted portion 34 is smoothly guided and inserted into the insertion groove 44.

A through hole 43b for accessing the insertion hole 41a is formed on the rear side of the holding portion 43.

A locking hole 43c, into which the locking piece 34a locks, is formed at the middle and slightly front side of the holding portion 43. The locking hole 43c is a long hole whose longitudinal direction extends in the vertical direction, and is open at the upper side (see FIG. 5). That is, the locking hole 43c is open on one side (upper side) in the vertical direction perpendicular to the insertion direction (front-back direction).

As a result, by moving the first hardware 30 upward with respect to the second hardware 40, the locking piece 34a is detached from the locking hole 43c, and the first hardware 30 and the second hardware 40 are easily separated. It is now possible to do so. That is, after use, the front panel 1A and the left panel 1B can be easily separated by sliding the front panel 1A upward with respect to the left panel 1B.

The cushion board 20 is arranged on the right side of the holding part 43, and the front end of the cushion board 20 is fixed to the holding part 43 with a pin 70. Note that the pin 70 is an accessory (part) of the second hardware 40. Alternatively, the second hardware 40 may include a U-shaped holding part into which the front end of the cushion board 20 is inserted and which holds the front end.

<Bolt>
The bolt 50 is a member that protrudes vertically downward from the lower surface 12 of the board material 10 and whose protrusion length is adjustable. The bolt 50 includes a hexagonal head 51 and a male threaded portion 52 (shaft) that extends vertically upward from the head 51 and is threaded into the bolt hole 13 .

By rotating the bolt 50, the length of the bolt 50 that projects vertically downward from the lower surface 12 can be varied. Note that the protruding lengths of the two bolts 50, 50 can be adjusted independently.

As a result, after the panel 1 is fixed to the side surface 101 of the column 100, the protruding length of the bolt 50 is adjusted so that the head 51 of the bolt 50 comes into contact with the floor surface, so that the panel touches the floor surface in the vertical direction. Supported. This makes it difficult for the panel 1 to shift in the vertical direction thereafter.

The bolt 60 is a member that protrudes vertically upward from the upper surface 14 of the board material 10 and whose protrusion length is adjustable. The bolt 60 includes a head 61 and a male threaded portion 62 (shaft portion) that extends vertically upward from the head 61 and is threaded into the bolt hole 15 .

By rotating the bolt 60, the length of the bolt 60 that projects vertically upward from the top surface 14 can be varied. As a result, after the panel 1 is fixed to the side surface 101 of the column 100, the protruding length of the bolt 60 is adjusted so that the head 61 of the bolt 60 comes into contact with the ceiling surface, thereby preventing the panel 1 from shifting in the vertical direction. Become.

≪Panel effect≫
According to such a panel 1, adjacent panels 1 can be connected to each other while holding the cushion board 20 using the first hardware 30 and the second hardware 40. As a result, if the cushion board 20 is made of rock wool and has fire resistance, even if the board material 10 is lost due to a fire, the adjacent cushion boards 20 connected by the first hardware 30 and the second hardware 40 will be remain. That is, the cushion board 20 connected by the first hardware 30 and the second hardware 40 functions as a fireproof material (fireproof coating) and prevents the pillar 100 from burning.

≪Panel construction method≫
Next, with reference to FIG. 2, a method of constructing panel 1 (1A to 1D) will be described. The construction method for the panel 1 is characterized by surrounding a square pillar 100 with four panels 1A to 1D, and connecting adjacent panels 1A to 1D to each other. However, the shape of the pillar 100 and the number of panels 1 are not limited to this.

<Fixing the first panel>
First, the first panel 1A is fixed to the side surface 101 of the pillar 100. Specifically, with the cushion board 20 placed on the pillar 100 side, the cushion board 20 is attached with double-sided tape or adhesive while maintaining the posture of the board material 10 along the vertical direction using a plumb bob or a laser. It is fixed (temporarily fixed) to the side surface 101 of the pillar 100 using an agent or the like.

In this case, when the side surface 101 of the pillar 100 is uneven (uneven), the cushion board 20 is deformed to correspond to the unevenness. Here, the unevenness of the side surface 101 is formed by, for example, a welded portion (welding trace) when a plurality of column base materials are connected by welding or the like in the vertical direction. In addition, the unevenness of the side surface 101 is formed by a step of a connecting metal fitting (connecting plate) that connects the side surfaces of a plurality of column base materials.

In this way, since the cushion board 20 deforms in accordance with the unevenness of the side surface 101, the board material 10 can be positioned in the vertical direction without being affected by the unevenness.

Then, the two bolts 50, 50 are rotated to adjust the protrusion length from the lower surface 12, and each head 51 is brought into contact with the floor surface of the construction site. Further, the two bolts 60, 60 are rotated to adjust the protrusion length from the upper surface 14, and each head 61 is brought into contact with the ceiling surface of the construction location. As a result, the panel 1A (board material 10) is supported by the floor from vertically below and is also in contact with the ceiling, making it difficult for the panel 1A to shift thereafter. Alternatively, a wedge may be inserted between the lower surface 12 and the floor surface to prevent displacement.

<Fixing the 2nd to 4th panels>
Next, the side edge of the second panel 1B (board material 10) is brought into contact with the side edge of the first panel 1A (board material 10), and the cushion board 20 is moved in accordance with the unevenness of the side surface 101. While deforming and aligning, insert the inserted portion 34 of the first hardware 30 into the insertion groove 44 of the second hardware 40 (see FIGS. 3 and 4). Then, the first hardware 30 and the second hardware 40 are connected, and as a result, the panel 1A and the panel 1B are connected. Here, panel 1B may be fixed to panel 1A with screws 81 (connecting portions), and panels 1A and 1B may be reinforced and connected. Note that instead of the screws 81, for example, nails, tenons, etc. may be used for fixing.

Here, since the panel 1A has already been positioned in the vertical direction, the panel 1B can be positioned in the vertical direction by bringing the panel 1B into contact with the panel 1A for alignment. That is, for the second panel 1B, positioning work using plumb bob, laser, etc. is not necessary. Further, since the two panels 1B are not fixed (temporarily fixed) to the side surface 101 of the pillar 100 using double-sided tape or the like, construction time is shortened.

Next, the third panel 1C is connected to the second panel 1B in the same manner.

Next, the fourth panel 1D is connected to the first panel 1A and the third panel 1C in the same manner.

As a result, the pillar 100 is surrounded by the four panels 1A to 1D, and the adjacent panels 1A to 1D are connected with the screws 81, so the four panels 1A to 1D are shifted vertically downward from the pillar 100. It becomes difficult. That is, since the entire four cushion boards 20 arranged inside the four panels 1A to 1D are deformed in accordance with the unevenness of each side surface 101, the four panels 1A to 1D are vertically disposed from the pillar 100. It becomes difficult to shift downward.

In this way, according to the construction method for Panel 1 and Panel 1, there is no need for the conventional base material runner material, and only the first panel 1A is positioned in the vertical direction using plumb strokes, etc., so Panel 1 Fixing work is omitted, reducing construction time.

≪Modification example≫
Although one embodiment of the present invention has been described above, the present invention is not limited thereto, and may be modified as follows, for example.

In the embodiment described above, the panel 1 covers the side surface of the pillar 100, but the panel 1 may also cover the surface of the wall (wall surface). That is, a plurality of panels 1 may be arranged in a planar direction along the surface of a wall and connected together.

In the embodiment described above, the bolt 50 is screwed into the bolt hole 13 of the board material 10, but in addition, for example, a metal material having an L-shape in side view that holds and supports the lower end of the board material 10 may be used. It is also possible to have a structure in which a support member is provided, and the bolt 50 is screwed into this support member. The same applies to the bolt 60.

In the embodiment described above, a configuration in which bolts 50 and bolts 60 are provided on the lower surface 12 and upper surface 14 of the board material 10 is illustrated, but in addition to/instead of this, for example, bolts may be provided on the back surface 11 of the board material 10. (a protrusion). By adjusting the protruding length of the bolt so that the bolt comes into contact with the pillar 100, the panel 1 can also be supported from the back surface 11 side.

In the above-described embodiment, the cushion board 20 is fixed to the board material 10 with the first metal fittings 30 and the second metal fittings 40, but in addition, for example, the cushion board 20 is fixed to the board material 10 with a suitable adhesive. It may also be configured such that it is adhered (fixed) to the back surface 11 of. Further, for example, when the cushion layer is formed of a urethane layer or the like, the cushion layer may be formed by spraying urethane resin onto the back surface 11 of the board material 10.
