A plurality of fastening holes (11) are vertically and vertically formed in the flat plate (1).

The fastening hole (11) silver The fastening shaft 32, which will be described later, of The fastener 322 is passed through the girder 2 when the fastening of the louver 1 and the girder 2 is completed, of A fastening hole (11) for supporting the lower portion of the upper flange of Only a part of them is located above the upper flange of the girder 2. [

The present invention relates to a flat plate fastening apparatus which comprises a guide pipe 31, a fastening shaft 32 and a fastening nut 33 which are located inside the fastening hole 11 and join the flat plate 1 and the girder 2 .

The guide tube (31) is inserted and fixed in the fastening hole (11) of the lid plate (1).

The guide plate 31 can be inserted into the fastening hole 11 of the lid plate 1 and fixed to the upper portion of the girder 2 in a fixed state.

The guide tube 31 can be fixed to the fastening hole 11 by welding.

The guide pipe 31 is formed in a vertically opened pipe shape. In the embodiment shown in Figs. 4 and 5, a cylindrical guide pipe 31 is shown.

An upper portion of the guide tube 31 is formed with a locking protrusion 311 for receiving and fixing a fixing nut 33 to be described later.

The fastening shaft 32 is inserted into the guide tube 31 so as to be movable upward and downward and comprises a body portion 321 and a fastener 322.

The body portion 321 is a rod having a long length in the up and down direction, and a thread is formed on the upper outer peripheral surface.

The fastener 322 is coupled to the lower end of the body portion 321 and is formed long in one direction so that both ends of the fastener 322 protrude outward from the body portion 321.

The fixture 322 passes through the lower portion of the guide pipe 31 and then rotates so that the portion protruding outwardly of the body portion 321 supports the lower flange of the upper flange of the girder 2 located under the lower plate 1.

The fixing nut 33 has a thread having a shape corresponding to the thread formed on the upper part of the body part 321 and is bolted to the upper part of the body part 321 of the fastening shaft 32.

The fixing nut 33 is accommodated in the upper portion of the guide tube 31 and the lower surface thereof is supported by the engaging protrusion 311 of the guide tube 31.

The fastening sequence of the present invention is described below with reference to FIG.

First, as shown in FIG. 2, a hollow plate 1 having a guide tube 31 inserted therein is placed in the upper portion of the girder 2.

Then, the fastening shaft 32 is inserted into the guide tube 31 (Fig. 5 (a)). In this case, the fastening shaft 32 may be inserted while being inserted into the guide pipe 31 to mount the seat plate 1 on the girder 2.

The body 321 and the fastener 322 are formed to have diameters smaller than the inner diameter of the guide pipe 31 so that the fastening shaft 32 can pass through the inside of the guide pipe 31.

Next, the fastener 322 of the fastening shaft 32 is lowered to the lower flange lower position of the girder 2 (Fig. 5 (b)).

At this time, it is preferable to lower the fastening shaft 32 in a state in which the fastener 322 of the fastening shaft 32 is in parallel with the longitudinal direction of the girder 2.

Thereafter, the fastening shaft 32 is rotated 90 degrees so that the fastener 322 is caught by the lower flange of the girder 2, while a fastening nut 33 is fastened on the body 321 of the fastening shaft 32 (Fig. 5 (c)).

Rotation of the fastening shaft 32 may be performed manually by an operator or by fastening the fastening nut 33 to the upper portion of the body portion 321 of the fastening shaft 32 to rotate the fastening nut 33 So that the fastening shaft 32 rotates together.

Then, the fixing nut 33 is rotated (Fig. 5 (d)).

At this time, the fixing nut 33 can be rotated using a separate fastening tool 4.

When the fixing nut 33 is rotated as described above, the fixing nut 33 is caught by the latching jaw 311 of the guide tube 31 and is held in place without descending, so that the fastening shaft 32 is moved upward, The bottom plate 322 is fixedly caught by the lower flange of the girder 2 so that the flat plate 1 and the girder 2 are engaged with each other (Fig.

As described above, in the case of using the flat plate fastening apparatus according to the present invention, since the connection between the flat plate 1 and the girder 2 is performed at the upper portion of the flat plate 1, the operation is simple and safe.

In addition, since the fixing nut 33 closes the upper portion of the fastening hole 11 formed in the flat plate 1, it is possible to prevent the penetration of the foreign matter and the storm, and the fastening shaft 32 is located inside the guide pipe 31 There is no concern about corrosion.

In addition, since the hollow plate 1 is fastened to the girder 2 by the bolt connection of the fastening shaft 32 and the fastening nut 33 located inside the guide tube 31, the fastening force It is possible to prevent degradation.

4 and 5, a stopper 323 may protrude from one side of the body portion 321 of the fastening shaft 32. As shown in FIG.

The stopper 323 is a portion which is caught on the upper flange of the girder 2.

Therefore, when the fastening shaft 32 is inserted into the guide tube 31, the stopper 323 is caught by the upper flange of the girder 2, thereby preventing the fastening shaft 32 from falling down below the guide tube 31 can do.

Here, the stopper 323 may be a circular plate, and preferably has the same shape as the inner circumferential surface of the guide pipe 31. [

The inside diameter of the guide pipe 31 is formed to be larger than the body portion 321 of the fastening shaft 32 so that the fastener 322 of the fastening shaft 32 can freely move.

Therefore, the fastening shaft 32 can be inclined when the fastening shaft 32 is vertically moved vertically.

The stopper 323 serves to prevent the engagement shaft 32 from coming off due to the detachment of the engagement shaft 32 and to guide the engagement shaft 32 in a vertical direction without being tilted. That is, the stopper 323 can slide the fastening shaft 32 in the vertical direction along the inner circumferential surface of the guide tube 31.

Of course, a uniform clearance must be secured between the stopper 323 and the inner circumferential surface of the guide pipe 31 for smooth upward and downward movement of the fastening shaft 32.

6, guide grooves 312 may be formed on both sides of the inner circumferential surface of the guide tube 31, respectively, to which both ends of the fastener 322 are inserted to guide the vertical movement.

The guide groove 312 guides the fastening shaft 32 so that the fastening shaft 32 can be lowered while maintaining the state where the fastener 322 is parallel to the longitudinal direction of the girder 2. [

7 is a perspective view showing another embodiment of the guide pipe.

A stopper 323 is protruded from one side of the body portion 321 of the coupling shaft 32. A stopper 323 is engaged with a lower portion of the guide pipe 31, A through hole 314 having a shape corresponding to the fixing part 322 may be formed at the center of the fixing part 313.

When the fastening shaft 32 is provided in advance in the guide pipe 31 fixed to the inside of the base plate 1, the fastening shaft 32 may be detached when the base plate 1 is moved or impacted.

7, when the engaging plate 313 is coupled to the lower portion of the guide tube 31, the stopper 323 is caught on the engaging plate 313, so that the engaging shaft 32 is not detached.

Since the fastener 322 must pass through the fastening plate 313, the through hole 314 having the same shape as the fastener 322 is formed.

A predetermined gap is secured between the fastener 322 and the through hole 314 so that the fastener 322 can smoothly pass through the through hole 314.

As shown in FIG. 8, a plurality of fixing grooves 331 for fixing the fastening tool 4 may be formed on the upper surface of the fixing nut 33.

It is advantageous to minimize the clearance between the fixing nut 33 and the inner circumferential surface of the guide pipe 31 in order to prevent foreign matter or the like from entering the guide pipe 31. [

The protrusions 41 of the fastening tool 4 having the protrusions 41 formed at the lower portion thereof are inserted into the fixing grooves 331 formed on the upper surface of the fixing nut 33 And then the fastening tool 4 can be rotated to fasten the fixing nut 33.
