Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for fixing a metal ceiling plate that can easily fix the metal ceiling plate that constitutes the ceiling of a building without using screws or the like. The present invention also relates to a metal ceiling plate suitable for implementing this method.

[Conventional technology]

Ceiling panels are fixed to the ceiling, which forms part of the interior of a building, in order to obtain a design effect and a sound absorption effect. There are various materials that can be used to make this ceiling board, but among them, metal ceiling boards made by bending painted metal plates have become widely used because of their excellent durability and fire resistance. It's here.

Conventional methods for fixing metal ceiling panels often involve attaching JISA6517 r architectural steel base material (
The method used was to fix multiple steel base materials in parallel at predetermined intervals and fasten metal ceiling panels to the steel base materials with tapping screws, as specified in the "Walls and Ceilings". .

That is, as shown in FIG. 6, the steel base material 7 has suspension bolts 7c suspended from the ceiling base material 6 (for example, a reinforced concrete slab in the case of a reinforced concrete structure), and is shaped upward in a U-shape (cross-sectional shape). The upper horizontal part of the hanger 7d, which has a portion formed at the lower end thereof, is fixed to the lower part of the hanging bolt 7c from both upper and lower sides with nuts 7f, and the field edge receiver 7b, which has a U-shaped cross section, is supported on the bottom horizontal part of the lower end of the hanger 7d. In this state, a plurality of fields 7a having a cross-sectional shape are perpendicular to the field edge receiver 7b and supported at a predetermined interval through clips 7e on the field edge receiver 7b. In addition, the conventional metal ceiling plate fixed to the bottom horizontal surface of the edge 7a of the base material 7 made of tR, as shown in FIG. The flange having screw holes 8 drilled at a distance is inserted into the hooking piece receiving hole 10 bored immediately below the flange of the ceiling plate to which the other edge is adjacently fixed. The structure was such that a locking piece 9 was formed to be locked. Then, with the screw holes 8 drilled in the flange of the metal ceiling board aligned with the horizontal plane of the bottom of the edge 7a, the tapping screws passed through the screw holes 8 are screwed into the field 17a. After inserting the hanging piece 9 of the next metal ceiling plate into the hanging piece receiving hole lO of the adjacent ceiling plate, which has already been screwed and fixed in the direction perpendicular to the edge 7a, The screw holes 8 formed in the flange formed on the opposite edge parallel to the edge where the hooking piece 9 is formed are aligned with the horizontal plane of the bottom of the edge 7a. The metal ceiling plates were sequentially fixed to the bottom horizontal surface of the edge 7a of the steel base material 7 in the longitudinal direction of the edge 7a by screwing with tapping screws.

However, in the method described above, when fixing metal ceiling plates to the steel base material 7, it is common practice to provide a small gap between adjacent metal ceiling plates in consideration of design. , it requires a great deal of effort to set the position of the tapping screw that penetrates the screw hole 8 drilled in the flange of the metal ceiling plate and screws into the bottom horizontal surface of the field 97a of the steel base material 7, In any case, as the ceiling panels 7a of the steel base material 7 are fixed one after another in the longitudinal direction, the deviation of the ceiling panels becomes large and the appearance is impaired, which requires the skill of the operator. Since it takes time and effort to screw in the tapping screws, there are problems in that work efficiency is low and the burden on the worker is heavy.

[Problem to be solved by the invention]

The present invention solves the above-mentioned problems of the prior art and allows not only skilled workers but also non-skilled workers to perform the work easily and in a short time, reducing the burden on the worker and improving work efficiency. An object of the present invention is to provide a method for fixing a metal ceiling plate and a metal ceiling plate suitable for carrying out the method.

[Means to solve the problem]

The present invention was developed as a result of various studies to solve such problems.In the conventional method, a metal ceiling plate is fixed to a base material made of #W with screws. Focusing on the fact that the work required to enter the ceiling increases the burden on workers and lowers work efficiency, we developed multiple elongated shapes with a lip-groove cross-section for the ceiling base material of buildings. The support members are fixed in parallel with each other at a predetermined interval with their bottoms open, and a hanging piece that is hung on the long support member is formed on one end edge of the supported side of the metal ceiling plate. Then, with the engagement side opposite to the side to be supported tilted away from the elongated support, insert the latch piece into the upper end of the lip of the elongated support, and then hook the elongated support. The metal ceiling plate is rotated about its latching position as a fulcrum, and the engagement side is inserted into the bottom opening of the elongated support member to attach it.

Next, the metal ceiling plate to be fixed next was held in an inclined state with its engagement side separated from the long support material by inserting a hanging piece into the upper end of the lip of the adjacent long support material. Later, the metal ceiling plate was rotated using its hanging position as a fulcrum, and the engagement piece provided on the edge of the engagement side opposite to the ceiling surface was attached to the elongated support member in front. A metal ceiling plate having a bent portion facing the ceiling surface at a predetermined location other than the portion on the edge opposite to the ceiling surface where the hanging piece is provided on the side of the metal ceiling plate to be supported; The present invention was completed by discovering that by sequentially repeating the operation of inserting and engaging a convex engagement receiving piece, metal ceiling panels could be successively fixed without screwing.

EMBODIMENT OF THE INVENTION Hereinafter, the method for fixing a metal ceiling plate according to the present invention will be described in detail with reference to the drawings, with reference to a metal ceiling plate suitable for carrying out the method.

Fig. 1 is a perspective view showing one embodiment of a metal ceiling plate suitable for carrying out the method of the present invention, and Fig. 2 shows a state in which the metal ceiling plate shown in Fig. 1 is fixed by the method of the present invention.

Figure 4 is B-BA in Figure 2! Expanded cross-sectional explanatory views, FIGS. 5A, 5B, and 5C are explanatory diagrams illustrating the implementation procedure of the method of the present invention.

The method of the present invention involves fixing a plurality of elongated supports each having a lip-groove cross-sectional shape to a ceiling base material of a building in parallel with each other at predetermined intervals with their bottoms open. The longitudinal direction of the support material is made parallel to the supported side edge that is bent on the back side with respect to the ceiling surface of the metal ceiling board, and the bottom opening of the long support material is made parallel to the supported side edge. With the engagement side of the metal ceiling plate located in a tilted state away from the elongated support, the upper end of the lip of the elongate support is placed on the side opposite to the ceiling surface of the supported side. After inserting and latching the latching piece provided at the end edge, rotate the metal ceiling plate using the latching position as a fulcrum, and insert the engaging side into the bottom opening of the long support member. Insert and install the next metal ceiling panel to be fixed, with the engaged side edge away from the elongated support member and the supported side edge attached to the upper end of the lip of the adjacent elongated support material. After inserting and latching the latching piece provided on the edge opposite to the ceiling surface, the metal ceiling plate is rotated using the latching position as a fulcrum, and the ceiling surface on the engagement side is rotated. The supported side of a metal ceiling plate with the engaging piece provided on the opposite edge attached to a long supporting member in front.

An engagement receiving piece that has a bent part facing the ceiling surface side at a predetermined location other than the part where the hooking piece of the edge opposite to the ceiling surface is provided, and has an upwardly convex shape. This is a method for fixing a metal ceiling board, which is characterized by sequentially repeating operations of inserting the metal ceiling board into the ceiling and engaging the ceiling board.

Here, the long supporting material to which the metal ceiling board is fixed is one with a lip groove shape in cross section. It is sufficient if the lip part of the bottom opening has a rising part on the inside like the specified single field edge, and the strength is at least as strong as that, especially as shown in Figs. 2 to 4. It is possible to easily obtain a long support material by using each member of the steel base material specified in JISA6517 r Steel base material for construction (walls/ceilings) as shown in .

A metal ceiling plate suitable for carrying out the method of the present invention will be described with reference to an embodiment shown in FIG.

The metal ceiling plate 2 according to the present invention, which is suitable for carrying out the method of the present invention, has a supported side edge 2b bent on the back side with respect to the ceiling surface 2a, and a supported side edge 2b on the opposite side. The engagement side 2C is located parallel to the side 2C, and the bottom opening of the elongated support 1 is provided at the edge of the supported side 2b on the side opposite to the ceiling surface 2a (on the back side of the ceiling). A hanging piece 3 is bent almost parallel to the ceiling surface 2a so as to be hung on and supported by the upper end of the lip part of the ceiling. An engagement receiving piece 4 having a bent portion 4a facing the ceiling surface 2a side and having a convex shape is formed on the engagement side edge 2c opposite to the supported side edge 2b. On the edge of the opposite side (behind the ceiling) of the ceiling surface 2a, there is an engagement piece 5 having an upwardly convex shape that is engaged with the engagement receiving piece 4.
It is formed at the corresponding position.

The hanging pieces 3 and the engagement receiving pieces 4 of the metal ceiling plate 2 may be formed at any location on the supported side 2b, but they may be divided into two or more locations with an appropriate interval between them. It is preferable that the engaging piece 5 is made of metal, and the engaging piece 5 is supported by the engaging piece 3 already being engaged with the upper end of the lip of the bottom opening of the elongated support member l, as shown in FIG. Since it engages with the engagement receiving piece 4 of the ceiling panel 2, the shape is approximately the same as that of the engaging receiving piece 4 in order to prevent rattling when the engaging piece 5 is engaged within the engaging receiving piece 4. It is preferable that they have matching shapes, and at least one of the engaging piece 5 and the engaging receiving piece 4 should have elasticity. In addition, in the case of the engagement receiving piece 4, the supported side side 2b
It is desirable that the tongue apart from the metal ceiling plate 2 is formed in a shape that can be displaced around the folded part that forms an upward convex shape. (not shown) may be perforated and a sound absorbing material (not shown) may be provided on the back side.

To carry out the method of the present invention, first, the ceiling base material 6 of the building is
A plurality of elongated supporting members 1 each having a lip groove cross-sectional shape are fixed in parallel with each other at predetermined intervals with their bottoms open. This fixing method is not particularly limited, but fixing in the same manner as the conventional method described above is preferred because fixing members and the like are easily available. As mentioned above, this elongated support material 1 has a part rising inward from the lip part of the lip groove shape like a single field edge stipulated in JISA6517r "Steel base materials for construction (walls/ceilings)". 1a is preferable because the position of the engagement receiving piece 4 of the metal ceiling plate 2 can be defined more accurately.

After the elongated supporting material 1 is fixed to the ceiling base material 6 of the building in this way, the longitudinal direction of the elongated supporting material 1 is made parallel to the supported side side 2b of the metal ceiling board 2, and the elongated supporting material 1 is At the bottom opening of the ceiling surface 2 of the supported side 2b, the engagement side 2c of the metal ceiling plate 2 is separated from the elongated support l, so to speak, in an inclined state.
After inserting the hooking piece 3 provided on the edge opposite to a and hooking the hooking piece 3 to the upper end of the lip of the elongated support member 1, attach the metal ceiling plate 2 to that hook. It is rotated about the stop position as a fulcrum, and the engagement side 2c is inserted into the bottom opening of the elongated support member 1 to attach it. This operation completes the installation of the metal ceiling plate 2, on which the hanging piece 3 is hung on the upper end of the lip of the bottom opening of the long support l. If the elongated support member 1 on the engagement side 2c side of the ceiling plate 2 is not sufficiently attached to the bottom opening, the engagement side 2c of the metal ceiling plate 2 to be attached first.
Only the sides may be firmly held by, for example, a surrounding edge fixed to the wall of a building. Next, the metal ceiling plate 2 to be fixed next is placed in an inclined state with its engagement side 2c separated from the long support 1, and the supported side 2b of the metal ceiling plate 2 is placed on the upper end of the lip of the adjacent long support 1. After inserting and latching the latching piece 3 provided on the edge opposite to the ceiling surface 2a, the metal ceiling plate 2 is rotated using the latching position as a fulcrum, and the engaging side 2c is rotated.
An engagement piece 5 provided on the edge opposite to the ceiling surface 2a of
The end of the metal ceiling plate 2 attached to the elongated support member 1 in front is attached at a predetermined location other than the part where the hanging piece 3 is provided on the edge opposite to the ceiling surface 2a of the side 2b of the supported side 2b. It is sufficient to sequentially repeat the operation of inserting and engaging the engagement receiving piece 4, which has a bent part 4a facing the ceiling surface 2a side and is convex upward.

[For production]

As described above, the method for fixing a metal ceiling board according to the present invention is as follows:
By using the metal ceiling plate 2 suitable for carrying out this method, the metal ceiling plate 2 can be used without using screws.
can be fixed. That is, the hooking piece 3 formed on the side 2b of the supported material of the metal ceiling plate 2 is separated from the long support 1 by the engaging side 2c located parallel to the supported side 2b. The elongated support member 1 is held in a tilted state.
After inserting and latching the metal ceiling plate 2 into the upper end of the lip part, the metal ceiling plate 2 is rotated using the latching position as a fulcrum, and the engaging side 2c is inserted into the bottom opening of the elongated support 1. The metal ceiling plate 2 to be installed and then fixed is attached to the long support member 1 by the engaging side 2c in the same way as the metal ceiling plate 2 previously installed.
After inserting it into the upper end of the lip part of the adjacent elongated support member 1 in a tilted state away from the support member 1 and latching it, rotate it using the latching position as a fulcrum to oppose the ceiling surface 28 of the engagement side 2c. Latching of the edge opposite to the ceiling surface 2a of the supported side 2b of the metal ceiling plate 2, which has the engagement piece 5 provided on the side edge attached to the elongated support member 1 in front of it. A bent portion 4 facing toward the ceiling surface 2a at the end at a predetermined location other than the portion where the piece 3 is provided.
The metal ceiling plate 2 can be fixed to the elongated support member l by sequentially repeating the operation of inserting and engaging the engagement receiving piece 4 which has a shape a and has a convex shape on top. .

Therefore, the structure is directly hung on a plurality of elongated support members 1 whose bottoms are open parallel to the ceiling base material 6 of the building and whose cross-sectional shape has a lip groove shape and which are fixed at predetermined intervals. Only the hanging piece 3 is attached to the metal ceiling plate 2, and each metal ceiling plate 2 has a hanging piece 3 of the metal ceiling plate 2 and the metal ceiling plate 2 to which the hanging piece 3 is attached first. It is supported by the bent portion 4a at the end of the joint receiving piece 4 facing toward the ceiling surface 2a.

In addition, when at least one of the engagement receiving piece 4 and the engagement piece 5 of the metal ceiling plate 2 is formed in an elastic shape, the engagement piece 5 is first latched to the latching piece 3. Since the metal ceiling plate 2 is engaged with the engagement receiving piece 4 of the metal ceiling plate 2 by a spring action, the fixing work becomes very easy.

Further, when a through hole is formed in the ceiling surface 2a of the metal ceiling plate 2 and a sound absorbing material is provided on the back side, reflection of sound waves on the metal ceiling plate can be prevented.

〔Effect of the invention〕

As described in detail above, according to the method of the present invention, the metal ceiling plate is fixed by sequentially performing the operations of hooking the metal ceiling plate to the elongated supporting member, so there is no need to use screws.

Therefore, unlike the conventional method, the work of screwing in a tapping screw is not required, which not only reduces the burden on the worker but also allows the work to be completed in a short time, resulting in good work efficiency. Furthermore, the metal ceiling plate is formed with a hanging piece, an engaging piece, and an engaging piece at predetermined locations, and they are engaged in sequence using the method described above, so even if there is a slight deviation, it can be corrected without the need of an expert. With this method, metal ceiling panels can be easily fixed without damaging the appearance. In addition, if at least one of the engagement piece and the engagement receiving piece of the metal ceiling plate is formed into an elastic shape, wobbling can be prevented and the engagement piece and the engagement receiving piece can be more securely engaged. It can be fixed together. If the metal ceiling plate is provided with a sound absorbing material, the metal ceiling plate prevents the reflection of sound waves, making it possible to create a comfortable space.
