Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a fixture for connecting and fixing a plurality of objects to be fixed to each other.

[0002]

2. Description of the Related Art Conventionally, for example, in a construction site, in order to connect and fix wall materials and floor materials to each other and install them on a floor surface or the like,

FIG.

A fixture as shown in FIG. 2 was used. This is a configuration in which a hole having the same diameter as the screw diameter of the fixing bolt is provided in a planar fixing plate, and a nut is attached to an end of the hole. The function is to align the holes formed in the object to be fixed such as the flooring material with the holes of the fixing plate, pass through the fixing bolts, and tighten the nuts to fix.

[0003]

[Problems to be solved by the invention]

(A) The conventional fixing device has a problem that workability is poor and efficiency is low. That is, if the position of the hole of the object to be fixed and the position of the hole of the fixing plate are slightly deviated, the fixing bolt cannot be passed through, so a careful alignment work is required. In particular, when the object to be fixed is a large and heavy object such as a flooring material for a building, it requires a great deal of labor to perform the alignment work and the correction work of the displacement. In addition, since it is difficult to confirm the positions of the holes when working in a dark place, it is difficult to perform accurate alignment work and work for correcting misalignment, resulting in extremely low work efficiency. Further, the fixing bolt needs to be screwed straight into the nut. If the fixing bolt is screwed in a slightly bent state, the thread of the bolt and the screw groove of the nut do not engage with each other and are caught. Each time the fixing bolt had to be removed and reinserted, the work efficiency was poor. Further, when the fixing bolt is screwed into the nut without being noticed in a bent state, the screw thread and the screw groove are crushed, and the fixing tool itself has to be replaced. (B) In the conventional fixing device, when a nut is mounted on the fixing plate, it is necessary to first form a frame for accommodating the nut on the fixing plate, and then weld the nut to the frame. Therefore, it takes time and effort to manufacture, resulting in high costs. The present invention has been made to solve such a problem, and an object of the present invention is to realize a fixture capable of efficiently and quickly connecting and fixing a plurality of objects to be fixed. At the same time, the cost is to be reduced.

[0004]

Means taken by the present invention are as follows. A T-shaped nut holding plate provided with holding holes at positions corresponding to the holes is superimposed on a fixing plate provided with a plurality of holes, and a T-shaped nut is inserted between the fixing plate and the T-shaped nut holding plate through the holding holes. Hold the nut. A bolt is screwed into the T-shaped nut through a hole in the fixing plate. In the fixing device having the above configuration, the hole provided in the fixing plate has a larger diameter than the screw diameter of the bolt, and the holding hole provided in the T-shaped nut holding plate has a larger diameter than the outer diameter of the T-shaped nut. The T-shaped nut holding plate is provided with a peripheral wall surrounding the top of the T-shaped nut at an interval, so that the T-shaped nut moves freely in the holding hole and the peripheral wall. The present invention is a fixture having the above configuration.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention operates as follows.
The fixture of the present invention is mounted on a base on which the object is to be installed and fixed, and the holes provided in the object are aligned with the positions of the holes in the fixing plate. Insert the bolt into the hole of the object. Since the bolt passes through the hole of the fixing plate and hits the T-shaped nut, it is tightened and fixed as it is. At this time, even when the positions of the holes of the object to be fixed and the holes of the fixing plate are not exactly aligned and slightly shifted, the bolt can be tightened and fixed. That is, since the T-shaped nut is held so as to be freely movable, even if the bolt and the T-shaped nut are misaligned, the T-shaped nut moves to the position of the bolt as the bolt is fed. And can be tightened straight. Even when the bolt is inserted obliquely, the tightening and fixing operation can be performed as it is. That is, when the bolts are to be screwed into the T-shaped nut obliquely, the T
The nut moves. This causes the bolt to rise straight up and screw straight into the T-shaped nut.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 3 is an exploded perspective view showing one embodiment of the present invention,

FIG. 4 is a front sectional view of an essential part of the same. A T-shaped nut holding plate (3) provided with a holding hole (4) at a position corresponding to the hole (2) is overlaid on a fixing plate (1) provided with a plurality of holes (2). The shape of the fixing plate (1) and the number and layout of the holes (2) and the holding holes (4) are not limited to the illustrated embodiment, but may depend on the number of the objects (B) to be fixed and the connection method. Is determined. A T-shaped nut holding plate (3) is provided between the fixing plate (1) and the T-shaped nut holding plate (3) through a holding hole (4).
Hold the nut (5). The T-shaped nut (5) is formed by protruding the edge of a cylindrical nut to form a tongue-shaped crown (51). Insert the cylindrical portion of the T-shaped nut (5) into the holding hole (4), and
1) is held between the fixing plate (1) and the T-shaped nut holding plate (3). T-shaped nut (5)
Then, a bolt (6) is screwed through the hole (2) of the fixing plate (1). In the fixing device constituted as described above, the hole (2) provided in the fixing plate (1) has a larger diameter than the screw diameter of the bolt (6), and the holding hole (4) provided in the T-shaped nut holding plate (3). Is larger than the outer diameter of the T-shaped nut (5).
The T-shaped nut holding plate (3) has a peripheral wall (3) surrounding the top (51) of the T-shaped nut (5) at an interval.
1) is provided. More specifically, a recess is formed in the holding hole (4) portion of the T-shaped nut holding plate (3) by press working, and a side wall forming the recess serves as a peripheral wall (31). As described above, the T-shaped nut (5) becomes freely movable in the holding hole (4) and the peripheral wall (31). The fixing plate (1) and the T-shaped nut holding plate (3) are fixed by welding or the like. The present invention is a fixture having the above configuration.

Next, the operation of the present invention will be described with reference to the drawings.

As shown in FIG. 5, the fixture (A) of the present invention is attached to a base (C) on which an object to be fixed (B) is to be installed and fixed using a support or a support. The fixed object (B) is, for example, a floor material or a wall material for a building, and the base (C) is a base of a floor surface or a wall surface. A hole (B1) having the same diameter as the screw diameter of the bolt (6) is provided in the object (B), and the hole (B1) is aligned with the position of the hole (2) of the fixing plate (1). And the hole (B
Insert the bolt (6) into 1). The bolt (6) passes through the hole (2) of the fixing plate (1) and hits the T-shaped nut (5), so that it is tightened and fixed as it is. At this time, even if the positions of the center of the hole (B1) of the fixed object (B) and the center of the hole (2) of the fixing plate (1) are not correctly aligned and slightly shifted, the bolt (6) is tightened. Fixing work can be performed. That is, since the hole (2) provided in the fixing plate (1) is larger in diameter than the screw diameter of the bolt (6) and the hole (B1) of the fixed object (B), the hole (2) and the hole (2) Even if (B1) is slightly displaced, the bolt (6) can be inserted. Since the T-shaped nut (5) to which the bolt (6) is to be tightened is movably held in the holding hole (4) and the peripheral wall (31), the bolt (6) and the T-shaped nut (5) are fixed. ) Is different from

FIG. 6 shows that the T-shaped nut (5) moves to the position of the bolt (6) as the bolt (6) is fed in, so that it can be tightened straight. Even when the bolt (6) is inserted obliquely, the tightening and fixing operation can be performed as it is. That is

As shown in FIG. 7, when the bolt (6) is to be screwed obliquely with respect to the T-shaped nut (5), the T-shaped nut (5) moves so as to be straight with each other.
As a result, the bolt (6) is raised straight, and T
It is screwed straight on the nut (5). Although the T-shaped nut (5) is held movably and is not fixed, the bolt (6) is used because the peripheral wall (31) surrounding the crown (51) serves as a stopper. And the T-shaped nut (5) do not rotate together. As above

As shown in FIG. 8, a plurality of objects to be fixed (B) are fixed to a fixture (A) and connected to each other.

According to the structure of the fixture of the present invention, a T-shaped nut holding plate having holding holes at positions corresponding to the holes is superimposed on a fixing plate having a plurality of holes, and the fixing plate and the fixing plate are overlapped. A T-shaped nut is held between the T-shaped nut holding plates through holding holes, and a bolt is screwed into the T-shaped nut through a hole in the fixing plate. The diameter of the T-shaped nut holding plate is larger than the outer diameter of the T-shaped nut.
The T-shaped nut holding plate is characterized in that a peripheral wall surrounding the top of the T-shaped nut at intervals is provided so that the T-shaped nut floats in the holding hole and the peripheral wall. Therefore, the following specific effects can be obtained. (A) The fixture of the present invention connects a plurality of objects to be fixed to each other.
Excellent workability and efficiency in fixing work.
That is, even when the holes of the fixed object and the holes of the fixing plate are not exactly aligned and slightly displaced, the bolts can be inserted as they are because the holes of the fixing plate have a large diameter. As for the displacement between the bolt and the T-shaped nut, the displacement is automatically corrected by moving the T-shaped nut held movably, and the bolt is tightened to the T-shaped nut as it is to perform the fixing work. It is possible. This eliminates the need for careful alignment work and misalignment correction work as in the case of conventional fixtures in which the nuts are fixed to the fixing plate, greatly speeding up connection and fixing work and saving labor. It will be realized. The effect is remarkable especially when the fixed object is a large and heavy object such as a floor material for construction which is hard to move. (B) Even when the bolt is obliquely inserted into the hole of the object to be fixed, the tightening and fixing operation can be performed as it is, so that the workability and efficiency are excellent. That is, when the bolt is to be screwed obliquely with respect to the T-shaped nut, the T-shaped nut moves and is automatically corrected to be straight to each other, so that the bolt can be screwed straight into the nut. Therefore, unlike the conventional fixing device in which the nut is fixed to the fixing plate, there is no need to take out and reinsert the bolt that has been inserted diagonally. There is no failure such as screwing the screw into the nut and crushing the screw thread and the screw groove to damage the fixture. (C) As described above, the fixture of the present invention can speed up the work of connecting and fixing a plurality of objects to be fixed and save labor, but is also excellent in cost. In other words, despite the special structure, the T-shaped nut used therein is a general-purpose product, and the T-shaped nut holding plate can be easily manufactured by press molding, so that cost reduction can be realized. .
