Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a method for installing decorative panels for buildings, which efficiently attaches decorative panels for covering and decorating ceilings or walls of buildings. .

[Prior art] In the case of building construction, decorative panels are often used to cover and decorate the concrete surfaces of ceilings or walls, especially the ceilings of underground passages in public buildings and the ceilings of subway station platforms. In addition to covering the concrete surface of many of the walls with press-formed decorative panels, it is common practice to cover the air supply and exhaust pipes and electrical conduits that run along this surface.

Normally, decorative panels are installed by arranging field fences on the surface of a base such as a concrete ceiling or wall, and using the field fences as scaffolding to fix the field fences at required intervals to form a so-called base. The decorative panel is attached through the .

In this case, there are several methods for fixing the decorative panel to the field edge using tufting screws, etc., but broadly speaking, the edges of the decorative panels are stacked on top of the field edge, and adjacent panels are fixed using screws. There are two methods: one method is to avoid overlapping the edges, and the other method is to screw each sheet individually.

Since the edges and screws are exposed in any case with this screw IF method of installation, a joint cover is generally installed along the edge of the panel to hide the screw heads. Not only is the installation with the fasteners complicated, but also the installation to the joints requires a considerable amount of effort, making the workability extremely poor.

That is, the conventional method generally used is the method shown in Fig. 6.7, in which both edges of the decorative panel 2 are attached to the field edges 1 fixed in parallel through field edge receivers (not shown). Pass 2a,
After attaching the IF individually with screws 3 and covering the entire surface of the base such as the ceiling, the edges 2a that meet on the edge 1
IF metal fittings 4 formed with a U-shaped cross section at appropriate intervals on -H of
are separately screwed and placed, and then the joint cover 5 is pressed and installed by fitting it onto the fastener 4.

Construction using this method requires first fixing the decorative panel and screwing in the fasteners 4, and moreover, two or more fasteners are required per side edge of the decorative panel. However, when attaching a large number of panels, it is extremely troublesome and inefficient.

[Problems to be Solved by the Invention] The present invention solves the various problems in the conventional decorative panels described above, particularly the attachment of the decorative panel to the edge of the decorative panel and the joint cover that is attached along the edge of the decorative panel. This was developed in view of the complexity of installation.

In view of the fact that conventionally the fixing of decorative panels and the fixing of joint covers were carried out separately, the present invention combines these two fixing operations into one and saves labor in screw fixing operations, thereby improving efficiency. Furthermore, the decorative panel for construction is characterized by reducing the number of mounting brackets required for fixing joint covers to improve efficiency, and further improving the ease of attaching joint covers by reducing the number of mounting brackets. The purpose is to provide an installation method.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention has greatly improved the mounting fittings for attaching joint covers. As a result, the mounting of the decorative panel to the field edge can be done at the same time by fastening the mounting bracket to the edge of the panel, simplifying the work that was previously done individually and improving work efficiency. It is in. To explain this in more detail, there are a field edge installed along the surface of a base such as a ceiling, a decorative panel that attaches both edges to the 9F edge, a mounting bracket that fixes the decorative panel, and an edge of the decorative panel. The above-mentioned mounting bracket has a cross-shaped plate piece that extends in all directions, with a pair of fitting pieces erected so as to oppose each other from both side edges of each plate piece, and the joint cover has a U-shaped cross section. First, a plurality of arbitrary edges are arranged and fixed in parallel to the base at intervals corresponding to the width of the decorative panel, and then a decorative panel is placed between the parallel edges. are pasted in the lengthwise and orthogonal directions of the wando edge so that each edge abuts against each other, and then the above-mentioned mounting bracket is placed in the center of the mounting bracket so as to be overlapped at the intersecting part where the corners of the decorative panel gather. Screw and fix the screws to the edge through the through hole, then attach the joint cover along the abutting edges of the decorative panels, and fit the fitting piece of the mounting bracket into the opening. An object of the present invention is to provide a method for installing architectural decorative panels, which is characterized in that they are fixedly attached.

[Function] The installation method of the present invention is based on the above-mentioned structure. After the decorative panels are laid out along the edge of the field, and the cross-shaped mounting brackets are screwed to the part where each corner gathers, four As the corner is fixed at once and the mounting bracket itself is also fixed to the edge of the field, the joint cover can be installed immediately.

Moreover, since this mounting bracket has a fitting piece on each of the four plate pieces that extend out in all directions, it is possible to fasten the joint covers along the four sides of the decorative panel, and the joint cover can be attached to these fitting pieces. It can be easily installed by simply pressing it.

Next, an embodiment illustrating the construction method of the present invention will be explained, and its characteristic points will be explained in detail.

[Example] Figure 1 is an enlarged perspective view of a mounting bracket according to the present invention, Figure 2 is an enlarged perspective view of a corner of a decorative panel, and Figure 3 is an enlarged perspective view of a corner of a decorative panel.
The figure is an enlarged view of the main parts before the joint cover is installed, and FIG. 4 is a front view taken in section along the line N-17 in FIG. 3 in a state where the installation is completed.

Reference numeral 1o in the drawing indicates a field edge that is fixed in parallel at a required interval to field edge supports 11 that are fixed and supported on a concrete base such as a ceiling (not shown) via anchor bolts, etc., and 12 is a field edge that is fixed in parallel at a required interval. A metal decorative panel 13 that is attached to a contact surface by passing both grade parts 12a between the edges.
fix this decorative panel to the edge of the field and install joint cover 1.
This is a mounting bracket that also serves as the mounting bracket for item 4.

The field edge 10 is arranged in parallel to the width interval that the edge 12a crosses in accordance with the width of the decorative panel 12 to be attached, and the decorative panel 12 is arranged so that both edges 12a are overlapped on the field edge and the edges of the adjacent panels are overlapped. The edge 12a and the field edge are made to abut each other at the center, and here a screw 15 is inserted into a hole provided at the center of the length of each edge 12a.
It is designed to be temporarily fixed to the field edge 1o through it.

The decorative panel 12 extends between the edges by temporarily fixing the screws 15, and is arranged so that the edges 12a abut against each other, thereby covering the surface of a base such as a ceiling (not shown).

FIG. 5 shows the above-mentioned decorative panel I2 temporarily fixed to the edge lO, and after the decorative panel is temporarily fixed, it is permanently fixed by screwing the mounting bracket 13.

As shown in FIGS. 1 and 3, the mounting bracket 13 has a plate piece 16 extending in all directions and a pair of fitting pieces 17 and 17 that stand upright from both side edges of each plate piece in an opposed manner. 4 pieces of board 1
A through hole 20 for passing the screw 19 is provided in the center portion (8) which is the center point of the extension of the screw 8.

The opposing fitting pieces 17 of this mounting bracket stand up at intervals that match the opening width of the joint cover 14, and their heights match the depth of the joint cover. An outwardly protruding bulge 21 is provided to enhance the engagement.

Note that ribs 22 are punched out on one surface of the mounting bracket including each plate piece to increase strength.

1] The ground cover 14 is made of a long H-shaped member made of aluminum alloy and has a U-shaped cross section, and here, locking claws 14a are integrally provided on the inner surfaces of the two opposing surfaces, and the bulging portion 21 of the mounting bracket is
It is intended to be engaged with.

In the illustrated embodiment, as shown in FIG. 2, a recess 23 recessed toward one side is provided at the corner of the edge 12a of the decorative panel, so that the rib 22 of the mounting bracket A13 can be received therein.

Now, after temporarily fixing each decorative panel 12 in the state shown in FIG. 5, the mounting bracket 13 according to the above-mentioned configuration is placed so as to overlap the intersection of the corners of the decorative panels, and the rib 22 is placed in the recess 23. When the upper surfaces of the four plate pieces 16 of the mounting bracket are substantially aligned with the upper surface of the edge 12a of the panel, screw the screw 19 through the through hole 2o into the edge lO to secure it. By tightening the screws 19, the mounting bracket 13 is integrally fixed to the edge 10, and the decorative panel 12 is also fixed at the same time.

The fixing material of this mounting bracket is then covered with the C joint cover 14 along the edge 12a that is aligned with the butt of the panel, and the fitting piece 17.17 is elastically inserted into the opening, and the bulge 21 and The attachment is completed by engaging the locking claw 14a.

Note that the joint covers 14 installed vertically and horizontally at the intersections of the mounting brackets 13 are in a heavy state, and one fitting piece cannot be engaged with the joint covers 14 in the vertical direction.
is a long material that covers the entire length, and the horizontal joint covers are short lengths that extend between the vertical joint covers to avoid weight and to cover the entire edge of the decorative panel to be pasted.

[Effect of the invention] The present invention is constructed as described above.

By fixing one mounting bracket with a screw at the intersection where the corners of the decorative panels meet, the corners of the four decorative panels can be fixed, and a foothold for installing the joint cover can be secured. On the other hand, since the above-mentioned mounting bracket has plate pieces extending in all directions, each of which is provided with a mounting piece serving as a mounting means, joint covers arranged vertically and horizontally can be omitted. It is possible to provide four attachment points in one item, so it is much easier and faster to attach multiple items than in the past, in which multiple items were each attached using multiple screws. This is extremely advantageous in terms of work.

Incidentally, the screws 15 for temporarily fixing the decorative panel are effective in the case of a large panel and improves workability, but in the case of a small panel, the screw fixing can be omitted.

That is, in the case of a small size, the mounting bracket 13 is installed at the part where the panels meet.
Temporarily tighten the screws 19 in advance, hold one side edge of the panel by pushing the corner of the panel under this mounting bracket, and then attach the mounting bracket to the corner of the other side edge. Attach it and temporarily fix it with screws, repeat this one after another, and tighten the screws 18 in order from the four corners that are fixed to fix the mounting bracket, thereby omitting the temporary fixing work. I can do it.

In addition, as explained above, the present invention allows the decorative panel fixed to the field edge to be fixed to the mounting bracket alone without overlapping the edges, and the joint cover uses its own springiness and the spring force of the fitting piece. Since it is engaged with the fitting, it can be easily removed by peeling off the joint cover, and next time you want to remove the decorative panel, loosen the four mounting brackets that hold the target panel in place with screws. If you remove it, you can remove it without removing other panels. Therefore, when performing water leak recovery work, electrical work, or new lighting installation work, only the necessary area of the decorative panel can be removed without removing the entire decorative panel. This is extremely effective as it allows these works to be carried out.

For mounting brackets to be used at the edges of ceilings or walls, it is sufficient to cut out one of the four plate pieces, and for mounting brackets to be used at corners, two should be cut out. It goes without saying that even in these cases, the invention can basically be carried out without detracting from the gist of the invention.
