JP-A-2002-209774

In the above-described conventional technique, the mounting rigidity to the floor surface is insufficient. For this reason, fixing to the floor as described in the literature is not practically sufficient, and fixing to the wall is also necessary. When trying to fix it to an existing wall, there were cases where the construction was difficult because the strength of the wall was unknown.

An object of the technology disclosed herein is to provide a front panel box that can be constructed regardless of the reinforcing state of the wall, together with a method for constructing the front panel box.

A front panel box in one aspect of the disclosed technology has a left panel, a right panel, a back panel connecting the rear parts of the left panel and the right panel, and an inner curtain panel connecting the front upper parts of the left panel and the right panel. However, it is intended for floor fixing, in which pilot holes for attaching fixing brackets are formed in the lower portions of the left and right side plates.

FIG. 2 is a perspective view showing the front panel box of FIG. 1 in a cut state; It is a perspective view which shows the fixing metal fitting in embodiment. FIG. 4 is a perspective view showing a state in which the front panel box is cut before fixing metal fittings are attached; FIG. 4 is a side cross-sectional view showing a state in which the front panel box is temporarily placed at the installation position; It is a perspective view which shows the state which temporarily placed the fixing metal fitting in the attachment position in the state which cut|disconnected part. It is an enlarged perspective view showing a partially cut state around the fixing bracket after construction.

Embodiments embodying the technology of the present disclosure will be described in detail with reference to the accompanying drawings. A front panel box 1 of this embodiment shown in FIG. A back plate 4 connects rear portions of the left side plate 2 and the right side plate 3. - 特許庁The inner curtain plate 5 connects the front upper parts of the left side plate 2 and the right side plate 3 to each other. The front panel box 1 further has a riser 6. As shown in FIG. The riser board 6 connects the front lower parts of the left side board 2 and the right side board 3. - 特許庁In the front panel box 1, each member of the left side plate 2, the right side plate 3, the back plate 4, and the inner curtain plate 5 is connected by dowels. The front panel box 1 as a whole has a rectangular parallelepiped shape with front, upper and lower openings.

The front panel box 1 is installed indoors and used. The front panel box 1 is actually used by a user with a front panel such as a door attached to the front and an upper component such as a washbowl attached to the upper portion. The front panel box 1 is a washbasin when the upper component is a washbowl.

2, the left side of the drawing is the rear surface of the front panel box 1, and the right side of the drawing is the front surface. A back plate 4 is arranged on the rear surface of the front panel box 1 . At the front surface of the front panel box 1, an opening is provided between an upper inner curtain plate 5 and a lower riser plate 6. - 特許庁When the user actually uses the front panel box 1, the opening is closed by the front panel as described above. Also visible in FIG. 2 is the inner surface of the right side plate 3 . Two fixing metal fittings 7 are attached to the lower end of the inner surface of the right side plate 3 . As shown in FIG. 1, two fixing metal fittings 7 are also attached to the lower end of the inner surface of the left side plate 2 .

The back plate 4 covers almost the entire rear surface of the front panel box 1. - 特許庁It is desirable that the rear panel 4 occupies 80% or more of the total height and width of the rear surface of the front panel box 1 . However, when the upper component is a plumbing product such as the aforementioned washbowl, the builder may make a hole in the back plate 4 during construction. It is for the installation of water supply pipes and water pipes. The back plate 4 is preferably a single plate. For example, a particle board with a decorative surface called solid core can be used as the back plate 4 . Since the back plate 4 has a large area, the rigidity of the front panel box 1 as a whole is high. If the back plate 4 is a single plate, the rigidity will be higher.

The inner curtain plate 5 has an L-shaped cross section having a horizontal portion 51 and a wall portion 52, as shown in FIG. The inner curtain plate 5 may be formed by assembling two flat plates in an L shape, or may be an integral plate. This shape of the inner panel 5 also contributes to the rigidity of the front panel box 1 as a whole.

In the inner curtain plate 5 , the wall portion 52 is positioned on the front end side of the horizontal portion 51 . The position of this wall portion 52 is also on the front end side with respect to the right side plate 3 and the left side plate 2 . That is, the wall portion 52 is positioned at the front end of the front panel box 1 as a whole. The height direction position of the wall portion 52 in the front panel box 1 is a position where the upper end of the wall portion 52 coincides with the upper ends of the right side plate 3 and the left side plate 2 . The horizontal portion 51 is located at the lower end with respect to the width of the wall portion 52 in the height direction. The position of the horizontal portion 51 in the height direction is located below the upper end of the front panel box 1 by the width of the wall portion 52 in the height direction. This arrangement of the wall section 52 and the horizontal section 51 is less restrictive to the installation of the aforementioned upper components. This arrangement is also advantageous for improving the rigidity of the front panel box 1 as a whole.

The fixture 7 will be explained. The fixture 7 has a vertical piece 71 and a horizontal piece 72 as shown in FIG. The vertical piece portion 71 and the horizontal piece portion 72 are connected by an angle portion 73 . The fixing metal fitting 7 is an L-shaped metal fitting in which a vertical piece portion 71 and a horizontal piece portion 72 are connected in an L shape. The vertical piece portion 71 is a portion attached to the inner surface of the left side plate 2 or the inner surface of the right side plate 3 in the front panel box 1 . The horizontal piece portion 72 is a portion that is fixed to the floor surface during construction of the front panel box 1 .

The fixing bracket 7 has several holes for fixing. Holes 74 and 75 are examples of the holes formed in the vertical piece portion 71 . Holes 76 and 77 are examples of the holes formed in the horizontal piece portion 72 . Of these, holes 75 and 77 are normal round holes for passing fastening members such as wood screws. The holes 74 and 76 are oblong holes unlike the holes 75 and 77 .

The hole 74 is a vertically elongated hole formed in the vertical piece portion 71 . Hereinafter, the slot 74 is called. The longitudinal direction of the elongated hole 74 is perpendicular to the angle portion 73 . The role of the elongated holes 74 is to adjust the mounting height of the fixing bracket 7 to the left side plate 2 or the mounting height of the fixing bracket 7 to the right side plate 3 in order to install the front panel box 1 horizontally. A hole 76 is a laterally elongated hole formed in the lateral piece portion 72 . Hereinafter, it will be referred to as a slot 76 . The longitudinal direction of the long hole 76 is parallel to the angle portion 73 . The role of the long hole 76 is to adjust the mounting position of the fixing bracket 7 on the floor surface in order to adjust the installation position of the front panel box 1 .

Construction of the front panel box 1 will be described. First, the front panel box 1 before construction will be described. The fixing bracket 7 is not attached to the front panel box 1 before construction. As shown in FIG. 4, pilot holes 21 are formed at two positions where the fixing metal fittings 7 are to be attached in the front panel box 1 before construction. The pilot hole 21 is formed on the inner surface of the right side plate 3 at a position near the lower end. The pilot hole 21 is a bottomed hole that does not reach the outer surface of the right side plate 3 .

The pilot hole 21 is a hole for mounting the fixture 7 . More specifically, the pilot hole 21 is a hole for screwing the elongated hole 74 of the vertical piece 71 . The position of the pilot hole 21 is set to a standard position without considering the individual situation of the floor surface where the front panel box 1 is installed. The pilot holes 21 are already formed when the front panel box 1 is shipped from the factory. Although not shown in FIG. 4, two pilot holes 21 are similarly formed near the lower end of the inner surface of the left side plate 2 . Before construction, the front panel box 1 does not have a pilot hole for screwing the hole 75 of the vertical piece 71 .

The front panel box 1 before construction is shipped from the factory to the construction site in a state in which the fixing metal fittings 7 are not attached and the pilot holes 21 are formed as described above. The fixing bracket 7 may be delivered to the construction site as a set with the front panel box 1 before construction, or may be delivered to the construction site from the shipping source of the fixing bracket 7 separately from the front panel box 1 before construction. good.

A construction procedure for the front panel box 1 will be described. The construction of the front panel box 1 is to install the front panel box 1 at the place where it is planned to be used indoors. At that time, unevenness adjustment is also performed to cope with the unevenness of the floor surface of the planned use location. Installation of the upper component and processing of the front panel box 1 for that purpose are also performed.

The outline of the construction procedure is as follows. They will be explained in order below.
1. Temporary placement2. 2. Attachment of fixing metal fittings 7; Attachment of accessories

"1. Temporary placement" will be described. The builder first places the front panel box 1 at the installation location as shown in FIG. This is called temporary placement. The temporarily placed front panel box 1 is on the floor surface 8 with the back plate 4 facing the wall surface 9 of the building. When it is necessary to process the back plate 4 during construction, the construction worker processes it while it is temporarily placed. For example, when supplying water and draining water to the wall surface 9 when the upper component is a washbowl, the builder needs to make holes in the back plate 4 for passing the water supply pipe and the drain pipe. When the upper component includes electrical equipment and receives power supply for it from the wall surface 9, the builder needs to make a hole in the back plate 4 for passing the power supply cord. The same is true for holes for passing gas lines when the superstructure includes gas-using equipment.

In a state in which the front panel box 1 is temporarily placed at the installation location, the builder can grasp the positions for drilling the holes for the above purpose. The builder can carry out the drilling work with a known tool such as a hole saw. The builder may remove the front panel box 1 from the temporary placement position before drilling. In this case, after determining the hole opening position, the builder temporarily removes the front panel box 1 from the temporary placement position, performs the hole opening work, and then returns the front panel box 1 to the temporary placement position. If there is no need to drill holes, the builder does not process the back plate 4. - 特許庁

Next, "2. Mounting of the fixture 7" will be described. The temporarily placed front panel box 1 is fixed to the floor surface 8 by fixing metal fittings 7 . Unevenness adjustment is also performed in the mounting work of the fixing metal fittings 7 for that purpose. The unevenness adjustment is to horizontally install the front panel box 1 regardless of the undulations of the floor surface 8 . The mounting of the fixture 7 including unevenness adjustment is performed in the following procedure.
2-1. Temporary placement of fixture 7 2-2. Drilling a pilot hole for the elongated hole 76 2-3. Temporary fixation of slot 74 and slot 76 2-4. Unevenness adjustment 2-5. permanent fixation

In “2-1. Temporary placement of fixtures 7”, the builder places four fixtures 7 at respective mounting positions. The installer places the horizontal piece 72 on the floor surface 8 and brings the standing vertical piece 71 into contact with the inner surface of the left side plate 2 and the inner surface of the right side plate 3 . The horizontal piece portion 72 of the placed fixture 7 is positioned on the floor surface 8 . The builder further adjusts the position of the fixture 7 so that the pilot hole 21 can be seen through the long hole 74 . In this state, the elongated hole 74 is positioned above the pilot hole 21 . In other words, pilot hole 21 is exposed through slot 74 . FIG. 6 shows this state.

In “2-2. Drilling a pilot hole for the long hole 76 ”, the builder drills a pilot hole 81 on the floor surface 8 within the area visible in the slot 76 . The position where the pilot hole 81 is made is preferably around the center of the range in the longitudinal direction of the elongated hole 76 . The builder carries out the operation of drilling the pilot holes 81 at the positions of the elongated holes 76 of the four fixtures 7 .

If the floor surface 8 is a dry floor, the builder drills a corresponding portion of the floor surface 8 through the long hole 76 to make a pilot hole 81 . If the floor surface 8 is a wet floor, the builder writes a mark on the floor surface 8 through the long hole 76 . Then, the builder temporarily removes the fixture 7 and drills a pilot hole 81 by applying a drill to the mark on the floor surface 8 . The builder inserts a known PC plug into the prepared pilot hole 81 and then returns the fixture 7 to its original position.

In “2-3. Temporary fixation of elongated holes 74 and 76”, the builder inserts the screws 10 (see FIG. 4) into the elongated holes 74 and 76 to temporarily fix them. The screw 10 is inserted through the elongated hole 74 into the pilot hole 21 and through the elongated hole 76 into the pilot hole 81, respectively. At this stage, it is not permanently fixed. Therefore, the builder tightens the screw 10 with a first tightening torque weaker than a second tightening torque, which will be described later. As a result, the vertical piece 71 is loosely fixed to the left side plate 2 and the right side plate 3 to such an extent that it does not move by itself but can slide in the vertical direction if a force is applied. The horizontal piece 72 is loosely fixed to the floor surface 8 to such an extent that it does not move by itself but can slide in the horizontal direction if a force is applied.

In "2-4. Unevenness adjustment", the builder performs unevenness adjustment using a known tool such as an adjuster bolt. The unevenness adjustment brings the front panel box 1 into a horizontal state. Due to unevenness adjustment, the fixing metal fitting 7 may slide slightly in the vertical direction. After that, the builder checks the state of contact between the horizontal piece portion 72 and the floor surface 8 for each fixture 7 . If there is a fixing bracket 7 with a horizontal piece 72 floating on the floor surface 8, the builder pushes the fixing bracket 7 downward to bring the horizontal piece 72 and the floor surface 8 into contact with each other. . At this time, not only the vertical piece 71 slides on the left side plate 2 and the right side plate 3 but also the horizontal piece 72 may slide slightly on the floor surface 8 . By this unevenness adjustment work, the position of the fixing bracket 7 with respect to the front panel box 1 is adjusted to a height that is individually matched to the installation position. The heights of the four fixing fittings 7 in one front panel box 1 may be slightly different from each other.

In “2-5. Permanent fixation”, the builder permanently fixes all of the holes 75, 77, slotted holes 74, and slotted holes . The specific procedure differs slightly depending on whether the floor surface 8 is a dry floor or a wet floor.

In the case of dry floors, the installer drills pilot holes at the locations of holes 75 and 77 . The builder applies a drill to the inner surface of the left side plate 2, the inner surface of the right side plate 3, and the floor surface 8 through the holes 75 and 77 to make pilot holes. After that, the screws 10 are inserted into the holes 75 and 77 and fixed. At this time, the front panel box 1 is not fixed loosely, but firmly fixed so that the front panel box 1 does not easily move even if force is applied. The builder also retightens the temporarily fixed screws 10 in the elongated holes 74 and 76 with a second tightening torque stronger than the first tightening torque to permanently fix them.

The procedure for wet floors is slightly more complicated than the above. The builder first marks the position of the hole 77 on the floor surface 8 . The builder temporarily releases the temporary fixing between the long hole 76 and the floor surface 8, and removes the front panel box 1 from the installation position. The builder applies a drill to the mark on the floor surface 8 to open a pilot hole, and inserts a known PC plug into the drilled pilot hole. The builder then returns the front panel box 1 to its original position. At this time, both the elongated holes 76 and the holes 77 are positioned above the pilot holes of the floor surface 8.例文帳に追加Then, the builder temporarily fixes the long hole 76 again.

Here, the builder again performs unevenness adjustment. The unevenness adjustment at this time can be done by fine adjustment. After that, the builder applies a drill to each position of the hole 75 in the left side plate 2 and the right side plate 3 to open a pilot hole. The installer inserts the screws 10 into the respective holes 75 and permanently fixes them to the left side plate 2 and the right side plate 3 . The builder inserts the screw 10 into each hole 77 and permanently fixes it to the floor surface 8 . The builder inserts the screw 10 again into each pilot hole 81 through each elongated hole 76 to permanently fix it to the floor surface 8 . The builder also retightens the temporarily fixed screws 10 in the elongated holes 74 to permanently fix them. The above is the final fixation procedure for wet floors.

"3. Attachment of attachments" will be described. The builder attaches accessories to the front panel box 1 that has been permanently fixed. Attachments to be attached here include a front panel such as a door attached to the front surface, and a decorative board for the riser 6, in addition to the above-described upper components. At this time, the builder also connects the water supply and drainage pipes for the upper structure, the power supply cord, and the equipment for them.

The procedure for constructing the front panel box 1 has been described above. In the front panel box 1 after this construction procedure has been carried out, the lower part of the left side plate 2 and the lower part of the right side plate 3 are fixed to the floor surface 8 by L-shaped fixing metal fittings 7 in a state in which they are unevenly adjusted. . More specifically, the inner surface of the left side plate 2 and the inner surface of the right side plate 3 are in contact with the vertical piece portion 71 , and the horizontal piece portion 72 is fixed to the floor surface 8 . As shown in FIG. 7, screws 10 are inserted into the inner surface of left side plate 2 and right side plate 3 through long holes 74 and holes 75 of vertical piece 71 . A screw 10 is inserted into the floor surface 8 through an elongated hole 76 and a hole 77 of the lateral piece 72 .

The front panel box 1 after construction is basically fixed to the floor surface 8 . The front panel box 1 is fixed to the floor surface 8 only within the height range of fixing metal fittings 7 arranged in contact with the floor surface 8. - 特許庁The wall 9 of the building faces the back plate 4 of the front panel box 1, but no measures are taken to fix the wall 9 and the back plate 4 together. Therefore, the builder need not consider the strength of the wall surface 9 when constructing the front panel box 1 .

As described in detail above, according to the present embodiment, the back plate 4 and the inner curtain plate 5 allow the front panel box 1 itself to have high rigidity. As the fixture 7, one having an L-shape and having at least a vertical piece 71 formed with a longitudinally elongated hole 74 is used. As a result, the height direction positions of the fixing metal fittings 7 can be individually and appropriately adjusted with respect to the front panel box 1 after unevenness adjustment. As a result, the front panel box 1 can be appropriately fixed to the floor surface 8 in an unevenly adjusted state without relying on the strength of the wall surface 9. - 特許庁In this way, the front panel box 1, which can be constructed regardless of the reinforcement condition of the wall surface 9, is realized together with the construction method.

This embodiment is merely an example, and does not limit the disclosed technology in any way. Therefore, the technology disclosed herein can naturally be improved and modified in various ways without departing from the gist thereof. For example, it is not essential that the back plate 4 is a single plate. As described above, from the standpoint of rigidity of the front panel box 1, a single plate is more advantageous. However, the technique of the present disclosure can be established even if the back plate 4 is a combination of a plurality of plates. It is also not essential that the inner curtain plate 5 has an L-shaped cross section. From the viewpoint of rigidity, the L-shaped cross section is more advantageous. However, the disclosed technology can be established even if the inner curtain plate 5 is a simple plate-like one. A configuration without the riser 6 is also possible. However, the presence of the riser plate 6 is advantageous from the viewpoint of rigidity.

The minimum requirements for the fixing bracket 7 are that it is an L-shaped bracket, that the vertical piece 71 is provided with an elongated hole 74, and that the horizontal piece 72 is provided with at least one of an elongated hole 76 and a hole 77. There are three things. However, in terms of construction, it is more preferable that the hole provided in the horizontal piece portion 72 is the elongated hole 76, and it is even more preferable that both the elongated hole 76 and the hole 77 are provided. It is more preferable that the vertical piece portion 71 also has a hole 75 in addition to the elongated hole 74 . For the holes 75 and 77 that are not temporarily fixed during construction, other fastening members such as nails may be used instead of the screws 10 .

The fixing position of the front panel box 1 to the floor surface 8 , that is, the mounting position of the fixing bracket 7 is not limited to the inner surfaces of the left side plate 2 and the right side plate 3 . If you don't care about the appearance, you may fix it on the outer surface. Not only the left side plate 2 and the right side plate 3, but also the back plate 4 and the riser plate 6 may be used for fixing. The front panel box 1 of this embodiment can also be installed like an island at a position away from the wall surface 9 of the building.
