Description

  The present invention relates to a reinforcing structure for a suspended ceiling.

  The suspended ceiling is generally composed of a suspension bolt (suspending material), a T bar (panel mounting material), and a ceiling panel material.

  The suspension bolt is formed in an elongated shape using, for example, a metal material so that the suspension ceiling can be disposed below the ceiling casing. Such a suspension bolt has one end joined to a skeletal member arranged inside the ceiling frame, while the other end is attached to the T-bar via a DX hanger and extends in the vertical direction. It is arranged to exist.

  The T bar is for attaching a ceiling panel material and is formed using a metal material.

  The ceiling panel material is attached to the lower end of the T bar and constitutes the ceiling.

  By the way, recently, there has been a relatively large earthquake with seismic intensity ranging from 5 to 6. In areas where the seismic intensity is between 5 and 6 strength, there is a case where the suspended ceiling provided inside the building may be damaged even in a building that can avoid structural damage.

  Therefore, in order to reduce the possibility of breakage of the suspended ceiling, there is a conventional suspension ceiling provided with a reinforcing brace.

  The reinforcing brace is arranged so that one end is attached to the vicinity of the upper end of the suspension bolt and the other end is attached to the T bar, and the inclination is made between the suspension bolt and the T bar by arranging as described above. (For example, refer to Patent Document 1).

  According to such a reinforcing brace, the suspension ceiling can be reinforced by connecting the suspension bolt and the T-bar, so that the possibility that the suspension ceiling is damaged by the force generated in the horizontal direction due to the occurrence of an earthquake is reduced. be able to.

  However, when the reinforcing brace is disposed as described above, an earthquake compressive force and a tensile force are applied to the reinforcing brace. At this time, the suspension bolt with which the reinforcing brace is engaged is applied with a compressive force corresponding to the vertical direction of the brace axial force and a tensile force corresponding to the vertical direction of the brace axial force. As described above, a compression force and a tensile force are applied to the suspension bolt. However, a suspension bolt formed of a metal material is weaker when a compression force is applied than when a tensile force is applied. There is a risk of bending due to the force applied and buckling due to the deflection. If the suspension bolt buckles, it will break the suspension ceiling.

  Therefore, in order to prevent the suspension ceiling from being damaged due to the buckling of the suspension bolt, a hollow steel pipe is conventionally provided between the ceiling casing and the ceiling panel material and covering the periphery of the suspension bolt. Was established.

  According to the suspended ceiling provided with such a hollow steel pipe, even if a force is applied in the vertical direction due to an external force such as an earthquake, the hollow steel pipe restrains the deflection in the out-of-plane direction caused by the compressive force applied to the suspension bolt. The possibility that the suspension bolt will buckle can be reduced.

JP-A-6-346547

  By the way, in order to provide the hollow steel pipe on the existing suspended ceiling, after removing the ceiling panel material from the T bar, the hollow steel pipe is provided around the suspension bolt, and then the ceiling panel material is attached to the lower end of the T bar again. Need arises. Therefore, there is a problem that the construction takes time.

  Therefore, in view of the above situation, the present invention can reduce the possibility that the suspended ceiling is damaged even when a force is applied in the vertical direction by an external force such as an earthquake, and the suspension that improves the workability of construction. It aims at providing the reinforcement structure of a ceiling.

  In order to achieve the above object, according to a first aspect of the present invention, there is provided a reinforcing structure for a suspended ceiling suspended from a ceiling casing by a suspension material, wherein a reinforcing means having a storage space for housing the suspension material is provided with a plurality of reinforcements. It is characterized by combining the members.

  A suspended ceiling reinforcing structure according to a second aspect of the present invention is characterized in that, in the first aspect, the reinforcing means is configured so that the suspension member and the reinforcing member are in contact with each other.

  A suspended ceiling reinforcing structure according to a third aspect of the present invention is characterized in that, in the first or second aspect, a holding means for holding the plurality of reinforcing members in a form having the storage space is provided.

  According to a fourth aspect of the present invention, there is provided the suspended ceiling reinforcing structure according to the third aspect, wherein the holding means is provided at regular intervals in the vertical direction.

  A suspended ceiling reinforcing structure according to a fifth aspect of the present invention is characterized in that, in the third aspect, the holding means is formed of an adhesive tape.

  According to the suspended ceiling reinforcing structure according to the present invention, the reinforcing means having the storage space for storing the suspension material is configured by combining a plurality of reinforcement members, so that the reinforcement member can be attached from the side of the suspension material. The workability when providing the reinforcing means on the existing suspended ceiling can be improved. Moreover, since the suspension material is stored in the storage space of the reinforcing means, the possibility that the suspension material buckles can be reduced. Therefore, according to this invention, a possibility that a suspended ceiling may be damaged can be reduced.

  According to the suspended ceiling reinforcing structure of the second aspect, since the reinforcing means is configured so that the suspension member and the reinforcement member are in contact with each other, the possibility of the suspension member buckling can be further reduced.
