Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ceiling plate holding structure, and more specifically, avoids the movement of the adjacent ceiling plate even when the ceiling plate for the inspection port is opened and closed so that the ceiling plate for the inspection port and the adjacent ceiling plate can be prevented from moving. The present invention relates to a technique for avoiding a gap between them.

[0002]

[Prior Art]

 When every other ceiling plate is lifted and opened to make it an inspection port for every other ceiling plate, the positions of other ceiling plates are displaced due to vibrations, etc., and there are gaps in the joints of the ceiling plates. It happens.

[0003]

[Problems to be solved by the device]

 In the past, the ceiling plate was hung and held by the hanging bar on the hanging bar, and the purpose was only to prevent the ceiling plate from falling off.Therefore, there was a gap in the joint of the ceiling plate. The problem could not be resolved. The present invention is intended to solve such a problem, and its purpose is to prevent the adjacent ceiling plate from moving even when the ceiling plate for the inspection port is opened and closed. Another object of the present invention is to provide a ceiling plate holding structure capable of reliably avoiding a gap from being generated between the ceiling plate and an adjacent ceiling plate.

[0004]

[Means for Solving the Problems]

 According to the present invention, both ends of a ceiling plate 3 are liftably mounted and held on a lower end horizontal piece 2 of a hanging bar 1 having a substantially inverted T-shaped cross section which is suspended and held in a substantially parallel manner in the back of the ceiling. A fixing bar 5 is engaged and connected to one ceiling plate 3a of the ceiling plates 3 arranged in a butted state in the longitudinal direction of the bar 1, and the fixing bar 5 is detachably fixed to the hanging bar 1. It is characterized by being fixed by the metal fitting means 4.

[0005]

As described above, both ends of the ceiling plate 3 are movably mounted and held on the lower end horizontal piece 2 of the suspension bar 1 having a substantially inverted T-shaped section which is suspended and held substantially parallel to the back of the ceiling. The fixing bar 5 is engaged and connected to one ceiling plate 3a of the ceiling plate 3 arranged in a butted state in the longitudinal direction of the hanging bar 1, and the fixing bar 5 is engaged with the hanging bar 1. By fixing with the detachable fixing metal fitting means 4, one ceiling plate 3a of the adjoining ceiling boards 3 is suspended by the fixing metal fitting means 4 via the fixing bar 5 which is engaged and connected thereto. The ceiling plate 3a on the fixed side does not shift its position even if the other ceiling plate 3b adjacent to the ceiling plate 3b is lifted to open the inspection port, and the joint between the ceiling plates 3a and 3b does not move. It is designed so that there is no gap in the.

【Example】

 A suspension bar 1 having a substantially inverted T-shaped cross section is suspended and held substantially parallel to the back of the ceiling. This suspension holding form may be any form. As shown in FIG. 1 (c), the hanging bar 1 has a locking piece 7 integrally formed on the upper portion of the vertical piece 6 in a diagonally downward direction. Both ends of the ceiling plate 3 are mounted and held on the lower horizontal piece 2 of the suspension bar 1. Engagement recesses 9 are formed at the ends of the ceiling plates 3 that are arranged in abutting relation in the length direction of the suspension bar 1 on the abutting side. A fixing bar 5 as shown in FIG. 4 (a) is engaged and held in an engaging recess 9 at an engaging piece 8 at the lower end of one ceiling plate 3a which is butted. On the upper portion of the fixing bar 5, an engagement holding portion 10 having a substantially inverted U shape is formed.

FIG. 3 shows a fixing metal fitting 11 as the fixing metal fitting means 4. The fixing metal fitting 11 is formed by bending an inserting piece 12 into the fixing bar 5 at a substantially right angle. The pressing piece 13 is formed by bending. A pressing piece 13 is also formed on the fixing metal fitting 11. A substantially U-shaped hooking piece 14 is formed on the upper end of the fixing metal fitting 11, and a locking claw 15 is cut and raised on the fixing metal fitting 11. In addition, a bent portion 16 is formed at the upper edge of the fixing metal fitting 11 at the end on the insertion piece 12 side.

Then, as shown in FIG. 1A, first, the locking piece 8 of the fixing bar 5 is inserted into the engaging recess 9 of the one ceiling plate 3a, and the fixing metal fitting 11 is inserted. Insert the piece 12 into the insertion holding portion 10 at an angle, and in this state, rotate the fixing metal fitting 11 as shown in FIG. 1B to insert the insertion piece 12 deeply into the insertion holding portion 10. Then, the hooking piece 14 of the fixing metal fitting 11 is hooked to the hanging bar 1 from above, the locking claw 15 is locked to the locking piece 7, and the fixing metal fitting 11 is pulled out upward from the hanging bar 1. It should be prevented. Then, the bent portion 16 is bent and locked to the upper surface of the suspension bar 1, and the insertion portion 12 is rotated to cause the bending portion 16 to oppose the force to pull out from the insertion holding portion 10. The rotation of the insertion piece 12 in the direction of pulling out the insertion piece 12 is prevented. As described above, the fixing metal fittings 11 for fixing the fixing bar 5 to the suspension bar 1 are collectively referred to as the fixing metal fitting means 4, but the configuration thereof can be modified in various ways. It is only necessary to have a metal fitting configuration that can be easily fixed to the suspension bar 1.

An engaging recess 9b is also formed on the other ceiling plate 3b arranged in abutting relationship with one ceiling plate 3a, and an engaging piece 8b formed on the movable bar 17 shown in FIG. 4B. To the engaging recess 9b, and the hanging portion 18 formed at the upper end of the movable bar 17 is loosely fitted onto the upper portion of the engaging holding portion 10 from above, and the other ceiling for the inspection port The plate 3b can be lifted up and opened with respect to the fixed ceiling plate 3a. The fixing bar 5 and the movable bar 17 are each formed with an abutting ridge 19, and the abutting ridge 19 abuts against each other so that no gap is formed in the joint portion.

In this way, both ends of the ceiling board 3 are movably mounted and held on the lower end horizontal piece 2 of the hanging bar 1 having a substantially inverted T-shaped cross section which is suspended and held substantially parallel to the back of the ceiling. The fixing bar 5 is engaged and connected to one ceiling plate 3a of the ceiling plate 3 arranged in a butted state in the longitudinal direction of the hanging bar 1, and the fixing bar 5 is engaged with the hanging bar 1. By fixing with the detachable fixing metal fitting means 4, one ceiling plate 3a of the adjacent ceiling boards 3 is suspended by the fixing metal fitting means 4 via the fixing bar 5 engaged and connected to the ceiling board 3a. The ceiling plate 3a on the fixed side does not shift its position even if the other ceiling plate 3b adjacent to this is lifted to open the inspection port, and the joint between the ceiling plates 3a and 3b does not shift. There is no gap between the parts.

[0011]

[Effect of the device]

 As described above, according to the present invention, both ends of the ceiling plate are liftably placed and held on the lower end horizontal piece of the hanging bar having a substantially inverted T-shaped cross section which is suspended and held substantially parallel to the ceiling. A fixing bar is engaged and connected to one ceiling plate of the ceiling plate that is arranged in abutting relation in the length direction of the bar, and this fixing bar is fixed to the suspension bar by a fixed metal fitting means. Since it is fixed, one ceiling plate of the adjacent ceiling plate is fixed to the hanging bar by the fixing metal fitting means through the fixing bar which is engaged and connected to the ceiling plate, and the other ceiling plate adjacent to this is lifted. Even if the inspection port is opened, the position of the ceiling plate on the fixed side does not shift, and there is an advantage that there is no gap in the joint between the ceiling plates.
