Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a ceiling structure in which a ceiling plate is spanned between main roof edges installed in parallel, a ceiling connecting fitting used in the structure, and a method for constructing the same. .

(Prior art) Conventionally, as a ceiling structure, for example,
There is one shown in Fig. 7 (Japanese Utility Model Publication No. 55-36658).

That is, a plurality of elongated main edges 1 having a substantially inverted T-shape in cross section and suspended in parallel at predetermined intervals on a ceiling base 6 made of 02w4 via hanging fixtures 7; T
A sub-edge 2 which has a letter-shaped shape and spans between the main edges 1 and 1 in a lattice-like manner via connecting fittings 3 attached to both ends, and the main edge! It consists of a ceiling board 8 having a square or rectangular planar shape and placed in a space formed by a sub-edge 2 and a ceiling board 8.

The connecting fitting 3 is made of a metal plate bent into a planar cross-shaped shape, and has a curved portion 4a formed by press working on one bent portion 4, and a locking portion formed by punching on the other bent portion 5. It has a protrusion 5a, and the bent portions 4, 5 are the guides 11ηla of the main field edge l.

1b and the guide grooves 2a, 2b of the secondary field edge 2 and are positioned, the curved portion 4a is caulked with the caulking tool 9, while the locking protrusion 5a is plastically deformed with a screwdriver, etc. and fixed. By doing so, the secondary field edge 2 is connected and integrated with the main field edge 1.

On the other hand, in recent years, various types of equipment have been installed in the ceilings of buildings, hotels, etc., and there has been an increasing need to check and maintain these ceilings and equipment, as well as to carry out additional work. It is desirable to have a structure that allows the ceiling to be wide open to secure a work space.

(Problem to be Solved by the Invention) However, in the above ceiling structure, since the secondary roof edge 2 is assembled by caulking the connecting fitting 3, once the ceiling is constructed, the secondary roof edge 2 is assembled. It was difficult to remove, and it got in the way of maintenance work on the equipment in the ceiling and reassembled wiring and piping, making the work difficult.

On the other hand, if the connecting fittings 3 are made of a soft metal plate that is easy to bend so that they can be removed by bending deformation, the connecting fittings 3 will be plastically deformed when each field edge vibrates due to an earthquake or the like. There was a problem in that the ceiling board 8 easily became loose and fell from the lattice-like space formed by the main rim 1 and the auxiliary rim 2.

Furthermore, since the connecting fittings 3 are fixed in a lattice pattern by spanning the main edge 1 and the secondary edge 2 by performing operations such as caulking, the work requires a large number of man-hours and a special crimping tool 9 is required. is necessary.

Therefore, the positioning work and the caulking work must be performed at the same time, and the subfield edge 2 is likely to shift during positioning, so that variations in positioning accuracy are likely to occur. Furthermore, there is a problem in that fine adjustment cannot be made after the connecting fitting 3 is fixed by caulking.

In addition, the construction method of the ceiling structure is such that after assembling the main roof edge 1 and the secondary roof edge 2 in a grid pattern, the main roof edge 1 and the secondary roof edge 2 are
The construction is carried out by dropping the ceiling board 8 into the space formed by. For this reason, the ceiling may be low, or
As shown in FIG. 14, when the ceiling base 6 intersected with the main roof edge l, it took time and effort to lower the ceiling board 8, resulting in poor workability. Therefore, in order to install the ceiling board 8 by lowering it, high positioning accuracy is required for the main roof edge 1 and the secondary roof edge 2, so there is a problem that ripe persimmons are required for construction.

In view of the above-mentioned problems, the present invention is designed so that not only the ceiling panel but also the sub-edge of the necessary part can be removed to open up a sufficient work space when performing maintenance on the attic. To provide a ceiling structure that is difficult to install, a finely adjustable connecting fitting that can be constructed with a high positioning accuracy without using any special work tools, and with a small number of man-hours, and a construction method that facilitates the work of mounting a ceiling board. With the goal.

It has a substantially inverted T-shaped cross section, a plurality of long main edges that are suspended from the ceiling base etc. and arranged in parallel at predetermined intervals, and a substantially inverted T or 0-shaped cross section; In a ceiling structure consisting of a plurality of sub-edges spanning between the main edges, and a planar rectangular ceiling plate spanning between the main edges and supported between the sub-edges, Vertically opposed guide grooves are provided on both sides of the vertical part of the main field edge, and spring connecting metal fittings having finger hooks are provided at both ends of the secondary field edge, and the connecting metal fittings are connected to the guide grooves. The structure is such that they are fitted and fixed in a removable manner by the reaction force of a spring.

Furthermore, the connecting fittings used in the ceiling structure according to the present invention are

The middle part can be fitted and fixed into the opposing guide grooves provided in the vertical part of the secondary edge, and both ends can be fixed in the opposing guide grooves provided in the vertical part of the main edge. It has a bent structure so that it can be slidably inserted into -7.

In addition, in order to achieve the above object, the ceiling construction method according to the present invention provides guides that are vertically opposed to both sides of the vertical part.
After suspending a plurality of long main roof edges each having an approximately inverted T-shaped cross section and arranging them in parallel at a predetermined interval from a ceiling base etc., a rectangular planar ceiling board is placed between the main roof edges; A secondary field edge having a substantially inverted T or O-shape in cross section and provided with connecting fittings having spring properties at both ends, and fitting the connecting fittings of the secondary field edge into the guide grooves of the main field edge. The step is to alternately slide and span the ceiling board in this state, and to support the opposing side ends of the ceiling board at the secondary edge.

(Function) Therefore, according to the ceiling +13 construction according to the present invention, normally both ends of the sub-edge are caused by the reaction force of the spring of the connecting fitting.
Since the main roof edge is fitted and fixed to the guide) 1 and 7, the fit will not loosen due to the reaction force of the rubber spring when vibrations such as earthquakes are applied to the roof edge material, and the When maintaining the equipment, lift the ceiling board and compress the connecting fittings of the sub-edge by placing your fingers on the finger rests.
It is possible to remove the sub-edge by removing it from the guide groove, making it possible to open a wide opening on the ceiling surface necessary for maintenance work.

Further, according to the connecting metal fitting according to the present invention, since it is fitted to the main field edge by the reaction force of the spring, the sub-field edge can be connected to the main field edge without performing caulking work.

Furthermore, according to the method for constructing a ceiling structure according to the present invention, each sub-edge is fitted into the guide groove of the main edge and slid by the reaction force of the spring of the connecting fitting. The structure is constructed by sliding both the sub-field verge and the ceiling board alternately to a predetermined position between the field verges.

The plurality of main edges 10 are suspended in parallel at predetermined intervals on a ceiling base 50 made of steel having a C-shaped cross section via hanging fittings 5I.

The secondary field edge 20 is made of a shape having approximately the same cross-sectional shape as the main field edge 1O, and has claw portions 21a cut and raised near both ends of its vertical portion 21 to prevent the connecting fittings 30, which will be described later, from being removed. Furthermore, the secondary field edge 20 cuts off both ends of the flange portion 24, and connects both ends of the vertical portion 21 to the flange portion of the main field edge 10. It is possible to place them on each of the four bridges and build them over the bridge.

Further, as shown in FIG. 4, the connecting fitting 30 of the present invention is made by bending a bar having spring properties into a substantially U-shape from the front and then into an abbreviated shape from the top. 33 is wide at the end.

In the ceiling construction method of the present invention, first, the connecting fittings 3

Note that 32a is a finger rest for removing the one end 32 of the connecting fitting 30 from the guide groove 13, and the finger rest 32a
When you put your finger on it and compress it, the connecting fitting 30 will connect to the main
The auxiliary field edge 20 can be removed by coming off the guide groove 13. The shape of the finger rest portion 32a is not limited to that shown in the drawings, but may be any shape that does not fit into the guide groove 13 and is large enough for a finger to rest on.

The ceiling plate 40 is a plate-like body with a substantially square plane that can be spanned over the main edges 10, 10, and has an annular step 41 on the lower edge.

Therefore, when forming the ceiling surface, first
The main field edges 10, 10 are suspended parallel to the stepped portion 41 of 0.
Place it on the flange part 14.14 of the ceiling board 40, push it sideways and slide it to a predetermined position to position it, then attach another sub-edge 20 in the same manner as described above and slide it to the opposite side of the ceiling board 40. The side end portions are supported by the flange portions 24 of the sub-edges 20, 20.

Thereafter, the construction of the ceiling is completed by repeating similar operations and alternately assembling the ceiling panels 40 and the sub-edges 20 between the main edges 10 and 10 suspended in parallel.

According to this embodiment, the ceiling board 40 and the sub-sill 20 are assembled by sliding them alternately, so the ceiling board 40 and the sub-sill 20 are sequentially placed from the periphery of the ceiling until they reach a predetermined position in a horizontal state. It only needs to be moved by sliding, and even if the ceiling is low or the ceiling base 50 made of shaped steel intersects with the main roof edge 10, the ceiling base 50 can be easily installed without getting in the way.

Moreover, since the connecting fitting 30 has spring properties, the both ends 32 and 33 of the connecting fitting 30 do not have to be caulked at each predetermined position as in the conventional example, and the connecting fittings 30 can be inserted into the guides d1 and 13 and 16 of the main edge lO. The main field edge 10 and the secondary field edge 20 can be connected and integrated at any location without using tools such as pliers.

In addition, even if vibrations from construction work, earthquakes, etc.
0 is elastically deformed by the spring action of both ends 32 and 33 and absorbs the strain caused by vibration, so it is difficult to loosen, the ceiling board 40 is hard to fall, and even after the ceiling surface is formed, the sub-field By utilizing the spring properties of the connecting fittings 30 provided on the edge 20, the sub-edge 20 can be removed from the main edge 10 using the finger rest 32a, and can be used as an opening for work such as maintenance in the attic. It has the advantage of being able to open wide.

As shown in FIGS. 6 and 7, the second embodiment is different from the above-mentioned embodiment in that the height of the main field edge IO and the subfield edge 20 is set to - to form a ceiling border. On the other hand, this is the case where the height of the secondary field edge 20 is made lower than the main field edge 1O.

For this reason, in this embodiment, a vertically long extension 34 is provided at one end 32 of the connecting fitting 30, and the guide i? +T
13 can be fitted.

In addition, in either the first embodiment or the second embodiment, it is not always necessary to provide the positioning notches 15a of the main field edge lO.

The rest is almost the same as the previous embodiment, so the explanation will be omitted.

In the third embodiment, as shown in FIGS. 8 and 9, in the first embodiment described above, the main edge is made of an extruded material such as aluminum having a substantially inverted T-shaped cross section. In contrast to the case where the secondary field edge 20 is constructed, a steel plate or the like is bent to form a substantially inverted H-shaped cross section, and guides 1M23.
26 is provided, and the secondary field edge 20 is +1. This sub-edge 20 is of a type in which the lower surface of the sub-edge is exposed to the ceiling surface in the first and second embodiments, whereas the lower flange portion 24 of the sub-edge 20 is attached to the ceiling plate 40. It is connected and supported by fitting into the end face.

The rest is the same as the first embodiment described above, so the explanation will be omitted.

Note that a protrusion 21b is provided on the vertical portion 21 of the sub-edge 20 in order to increase the rigidity in the longitudinal direction.

As shown in FIGS. 1O to 12, the secondary roof rim 20 of this embodiment is constructed by placing the ceiling board 40 and the secondary roof 20 alternately between the main roof rims t o and t o. , an r/i part 4 in which the flange part 24 of the sub-edge 20 is provided on the side end surface of the ceiling board 40.
The ceiling panels 40 are successively connected by sliding the ceiling panels 40 until they fit into the ceiling panels 2.

Therefore, both ends of the vertical portion 21 of the secondary field edge 20 are locked to the guides RT 13 , 16 of the main field edge IQ by the connecting fittings 30, while the flange portion 24 at the lower end is connected to the rib portion 14 of the main field edge 10. Of the ceiling board 40 placed on! By fitting into the ilf portion 42, the ceiling plate 40 is connected and supported.

The pond is the same as in the previous embodiment, so its explanation will be omitted.

(Effects of the Invention) As is clear from the above description, according to the ceiling structure according to the present invention, the secondary rim is connected to the guide groove of the main rim via the connecting metal fitting having spring properties and provided with a finger rest. Since it is integrated, even after the ceiling surface is formed, by removing the secondary roof edge, it is possible to create a wide opening in the main roof edge flj7, making maintenance and additional work on the attic equipment easy. . In addition, since the connecting part between the main field edge and the secondary field edge is connected by fitting the connecting metal fittings with spring properties and the guide II+T, even if vibration is applied to each field edge due to other reasons, the connecting metal fittings will not move. elastically deforms to absorb vibrations and prevent the connection from becoming loose. For this reason, the ceiling board is unlikely to fall from the lattice-like space consisting of the main and sub-edges.

Further, according to the connecting fitting according to the present invention, the rod-shaped material having spring properties is used as the guide d1 of the main edge! Since it is fitted and fixed by spring force, there is no need to perform clinching work using pliers, etc., so the ceiling edge can be connected quickly. Moreover,
Since it is formed by bending a rod-shaped material, the amount is B, and the total weight of the ceiling member can be reduced, reducing the load applied to the main roof edge and hanging members.

Furthermore, according to the construction method of the present invention, the ceiling panels and the secondary roof edges are alternately spanned between the main roof edges installed in parallel, and the ceiling panels and the secondary roof edges are positioned without sliding force. Even if the ceiling base intersects with the main roof edge, you can insert and place each ceiling board from the part with sufficient attic space, and then slide it to the specified position. Workability is good because the parts do not get in the way.Also,
Since the secondary roof edge and the ceiling board are alternately slid between the main roof edge, positioned and placed, the connection of the secondary roof edge and the construction of the ceiling board can be completed at the same time, reducing construction time. There is an effect.
