Description

  The present invention relates to a brace mounting bracket for firmly fixing a reinforcing brace used when a ceiling frame is suspended from a ceiling frame to a suspension bolt from the ceiling, and a method for handling the same.

When the ceiling frame is suspended from the ceiling frame, a reinforcing brace is generally used between the suspension bolt and the ceiling frame in order to ensure the seismic strength of the ceiling frame.
In the conventional ceiling structure, one end of the reinforcement brace is locked to the upper part of the suspension bolt suspended from the ceiling casing, and the other end of the reinforcement brace is fixed to the ceiling frame or another adjacent suspension bolt. As an example of the brace mounting bracket used for locking the reinforcement brace to the suspension bolt, a mounting bolt provided at the tip of the reinforcement brace is screwed into the substrate of the brace bracket and extends from the upper part of the substrate. A first locking portion capable of locking to a bolt, a second locking portion capable of locking to a suspension bolt extending from a lower portion of the substrate, and a first locking portion and a second locking portion; A brace fitting provided with a third locking portion disposed between and extending from the side of the second locking portion, wherein each mounting bolt screwed into the board is fastened to the suspension bolt. Between the three points of the locking part and the mounting bolt Proposed to fix the reinforcing brace to the hanger bolts it has also been made. (See Patent Document 1)
In addition to this, a nut portion provided on the base plate portion using a mounting bracket provided with a bolt portion at one end of the reinforcing brace and a locking piece formed in a bifurcated shape with different angles in the vertical direction from the base portion. The bolt part of the reinforcing brace is screwed in and placed so that it can be tightened, and each locking piece of the mounting bracket is locked to the hanging bolt, and the tip of the reinforcing brace is brought into contact with the hanging bolt while rotating the bolt part of the reinforcing brace. In addition, the ceiling reinforcing brace mounting structure in which the reinforcing brace is arranged on the suspension bolt by tightening the suspension bolt with the respective locking pieces and the bolt portion of the reinforcement brace can be seen. (See Patent Document 2)

  However, in any of the above proposals, the locking state of the suspension bolt and the mounting bracket is unstable at a plurality of locking points by the bolt portion of the reinforcing brace and the locking piece of the mounting bracket, and the reinforcing brace Since the mounting angle is limited, adjustment becomes impossible and a lot of work is required. In addition, since all the mounting brackets have an integral structure, eccentricity and torsion of the reinforcing brace and buckling phenomenon similar to the battledore occur when the ceiling frame or ceiling frame is impacted. When the ceiling frame moves up and down, there are many problems such as the possibility that the reinforcing brace may come off from the suspension bolt and fall off.

One end of the brace mounting bolt 11 is fixed to the brace mounting bolt holding frame 12 by welding or the like, and the brace mounting bolt holding frame 12 can be attached to the tip of the reinforcing brace by setting a bolt in the bolt hole 21. Yes.

[Example 2]
Another brace mounting bracket according to the present invention includes a support receiving plate for mounting a suspension bolt engaging piece half-threaded with a suspension bolt, a support side plate extending perpendicularly from both sides of the support receiving plate, and a movable stretched between the support side plates. The holding bracket formed from the mounting shaft of the holding bracket, and the guide plate and the brace mounting bolt for preventing inconsistency between the holding bracket supported by the mounting shaft mounted between the support side plates while holding the holding bracket. It consists of a movable holding bracket formed from a threaded screw part, and a brace mounting bolt that presses and fixes the suspension bolt while being screwed into the threaded thread part of the movable holding bracket and corresponding to the suspension bolt engaging piece. In addition, the movable holding metal fitting is securely and firmly formed while ensuring the locking to the suspension bolt while simplifying the movable holding metal fitting.

  In the other brace mounting bracket according to the present invention, since only a part of the movable holding bracket 7 attached to the holding bracket of the first embodiment described above is changed, it is simply configured. Only an Example is demonstrated based on the front view (a) of FIG. 5, a rear view (b), and the top view (c) seen from the downward direction.

The novel movable holding metal fitting 22 employed in this embodiment will be described based on a front view (a), a rear view (b), and a plan view (c) viewed from below in FIG.
The movable holding bracket 22 is composed of a base plate 23 and support side plates 25 and 26 that extend at right angles from both sides to form through holes 24, and braces inserted into the base plate 23 through the through holes 27. The point provided with the nut 28 for fastening and fixing the mounting bolt 11 is the same as that of the first embodiment.
Further, the substrate 23 cooperates with the support side plates 25, 26 at one of the positions orthogonal to the support side plates 25, 26 to prevent twisting with the holding bracket 6, and tighten the support side plates 25, 26 in the holding bracket 6. A guide plate 29 is formed to prevent over-passage, and the function of maintaining the function without hindrance in combination with the overall configuration of the brace mounting bracket 1 while having a simple configuration in which the mounting bolt guide plate is omitted. Yes.

  The movable holding metal fitting 22 configured as described above has a large mounting bolt guide plate 18 having a size corresponding to the size of the brace mounting bolt 11 when the size of the brace mounting bolt 11 is increased in relation to the reinforcing brace. Is provided on one side of the substrate 23, which increases the interval between the support side plates 25 and 26, and as a result, the holding metal fitting 6 is enlarged and the shape of the brace attachment metal 1 is increased. In order to avoid such a risk, the cost of the brace mounting bracket is reduced by eliminating the mounting bolt guide plate in which the mounting bolt guide hole is formed while taking into consideration the strength of the brace mounting bolt 11 and reducing the overall dimensions of the brace mounting bracket. That can provide a brace mounting bracket that can sufficiently cope with the eccentricity and twist of the reinforcing brace and the buckling phenomenon of the battledore even when the ceiling frame and ceiling frame are subjected to a huge impact It is.

Example 3
The method of handling the brace mounting bracket according to the present invention is such that the brace mounting bracket installed on the brace mounting bolt is arranged on the suspension bolt, and the brace mounting bracket is attached to the holding bracket of the brace mounting while adjusting the mounting position of the reinforcing brace to be set. Bracing attached to the support holding plate by half-threading the suspension bolt engaging piece with the suspension bolt, and then rotating the movable holding bracket with respect to the holding bracket along the mounting shaft. The brace mounting bracket provided on the reinforcement brace is firmly set on the suspension bolt by cooperating with the suspension bolt engaging piece while adjusting the bolt, and the brace mounting bracket provided on the reinforcement brace is used as the suspension bolt. This facilitates the work for fixing and firmly holds the reinforcing brace.
