BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a reinforcing brace for a ceiling which forms a unitized system ceiling by being framed in a grid by a T-bar or the like.

[0002]

2. Description of the Related Art Generally, in this type of unitized system ceiling structure, a reinforcing brace is provided between the suspension bolts suspended on the ceiling body in order to integrate the entire ceiling unit and improve the seismic strength. It is necessary to mount the base end on the side of the ceiling skeleton on the side of the ceiling surface (T bar).

By the way, conventionally, when attaching the reinforcement brace, as shown in JP-A-7-324427, an upper steady rest (7) is attached near the upper end of the suspension bolt (2), and these lower steady rests are attached. A channel (10) functioning as a steady brace (reinforcing brace) in the lateral direction orthogonal to the longitudinal direction of the field bridge (3) is obliquely provided between the (20) and the upper steady rest (7). It was designed to be hung over and attached. However, this is an installation at a high position when the upper steady rest (7) is installed, so a scaffold different from the scaffold for the unit ceiling must be assembled and the scaffold will be removed. Of course, extra work is forced,
The channel (10) is forced to be attached to each of the upper end side and the lower end side, which is a factor of poor work efficiency and high cost. Therefore, a separate scaffold is not required and the worker does not have to move. The advent of a reinforced brace attachment structure capable of doing so has been desired. Note that the reference numerals attached with the parentheses () are the reference numerals used in the above publication.

[0004]

DISCLOSURE OF THE INVENTION The present invention was devised to eliminate the above-mentioned problems, and when a reinforcing brace is installed while being slanted between suspended hanging bolts, The mounting bracket can be mounted on the top of the hanging bolt simply by hooking the mounting bracket on the tip side and rotating it on the proximal side, and all the mounting work including adjusting the tension of the reinforcing brace is on the proximal side. Since it can be carried out with no need for a separate scaffold and the worker can easily attach it without moving, the work cost can be reduced and the workability can be improved. Moreover,
Since the locking pieces of the mounting bracket are bifurcated, they can be supported independently so that component force acts on the hanging bolt at right angles or diagonal directions. Even if an error adjustment is required due to this, the upper end of the bolt can be used as a fulcrum to support either the upper locking piece or the lower locking piece, and the ceiling can be used in response to mounting errors. The purpose of the present invention is to provide a mounting structure for a reinforcing brace.

Since the upper locking piece 62 is configured to be longer than the lower locking piece 63, the lower locking portion 63a is suspended even when the mounting metal fitting 6 is turned sideways when locking. When the bolt 2 is locked and laterally pressed, it naturally stands up and the upper locking portion 62a
Is followed and locked. Further, although the tip of the bolt portion 51 is directly brought into contact with the suspension bolt 2, the bolt portion is configured to be indirectly performed through the movable contact plate, and the suspension bolt 2 is locked at the tip side. The locking portions 62a and 63a may be locked at the lower end side and the contact plate may be abutted from the opposite side (outside).

Further, since the upper engaging piece 62 is formed so as to be substantially on the extension line of the reinforcing brace 5, an optimum truss moment can be obtained when the reinforcing brace 5 is attached in an inclined manner. In addition to the advantage, since the mounting member 6 is provided with the support piece 64 that supports the tip edge of the bolt portion 51, the bolt portion 51 that moves forward and backward from the nut portion 61 is prevented from swinging, and the hanging bolt 2 is provided. It is possible to accurately guide the contact with respect to, and when the contact is made, it is possible to support the tip portion so that a bending stress is not applied between the nut portions 61.

Further, since the engaging portions 62a and 63a are formed in hook shapes, they are easy to install and, in addition to being laterally shaken by an earthquake or the like, they are inadvertently disengaged from the longitudinal shake. There is nothing.

Since the mounting member 6 is formed by bending a plate-like member to form a nut portion and upper and lower engaging pieces 62 and 63, it is only necessary to adjust the bending at an angle setting other than 45 degrees. Since the engaging portions 62a and 63a are notched in a substantially C-shaped hook shape, the engaging action with the bolt groove of the hanging bolt 2 (in particular, the upper engaging portion 62a) is performed. Deviation is regulated. In the mounting bracket 6, the vertically elongated metal plate is placed in the up-down direction and the upper locking piece 62 and the lower locking piece 63 are bent in a trapezoidal shape, but the invention is not limited to this.
It may be formed by bending a horizontally long metal plate.

Further, the reinforcing brace 5 according to the first embodiment.
Since the main body is composed of the channel material 5a and the bolt portion 51 is assembled to the channel material 5a with a screw, if the screw fixing hole is made a long hole, the mounting angle of the bolt portion 51 can be increased. There is an advantage that adjustment can be performed easily.

On the other hand, the reinforcing brace 5 according to the second embodiment.
Since the main body itself is composed of the bolt material 5b, the bolt portion 51 is integrally formed, which makes it unnecessary to separately manufacture and assemble the bolt portion 51 as compared with the first embodiment.
There is an advantage that costs can be reduced.
