BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a tool for attaching a field edge to a field edge in the construction of a foundation of a built-up ceiling of a building.
[0002]
[Prior art]
As shown in FIG. 6, FIG. 7, or FIG. 8, the foundation of the building ceiling is a steel field edge 200 on a plurality of mounting brackets 300 provided at a predetermined interval on a steel field edge receiver 100. Are installed one by one so as to be substantially orthogonal to the field edge holder 100. The mounting bracket 300 has a pair of sandwiching pieces 301 that sandwich the field edge 200 by engaging the recess 202 on the side surface of the field edge 200 with each upper end inclined to the inside. The fitting fitting 300 is press-fitted and fitted from below.
[0003]
When the field edge 200 is fitted to the mounting bracket 300, it is difficult to apply a pressing force sufficient to fit the field edge 200 to the mounting bracket 300 simply by pushing up the field edge 200 from below. In order to facilitate fitting, a field edge fitting 50 has been proposed.
[0004]
As shown in FIG. 6, the conventional field edge fitting 50 includes a long handle 53 in which two limb pieces 52 </ b> L and 52 </ b> R made of a rectangular material are joined to one end of a rod-like main body 51, and a belt-like shape. Two locking pieces 54L, 54R extending forward from the upper ends of both limb pieces 52L, 52R by bending one end of a steel plate extending in a hook shape, and both limb pieces 52L, 52R And a pressing member 55 made of a rectangular material laid between the two.
[0005]
The attachment of the field edge 200 to the attachment fitting 300 using the field edge attachment 50 is performed in the following procedure.
First, both ends of the field edge 200 are attached to the mounting bracket 300 by any means, and the field edge 200 is temporarily fixed to the field edge receiver 100. The both ends can be easily attached. At this time, the middle portion of the field edge 200 is located just below the mounting bracket 300 to which the field edge receiver 100 in the middle portion is attached, but is not fitted and is slightly bent. Yes. It is the role of the field edge fitting 50 to fit the field edge receiver 100 and the field edge 200 in this state. For this purpose, as shown in FIGS. 6 and 7, the field edge fixture 50 is held so that the locking pieces 54L and 54R extend forward, and the field edge 200 is sandwiched between the both leg pieces 52L and 52R. Then, the locking pieces 54L and 54R are hooked on the field receiver 100. In this state, the lower end portion of the handle 53 is pulled up to the near side.
Accordingly, as shown in FIG. 7, the field edge fixture 50 acts in this manner with the tip portions of the locking pieces 54 </ b> L and 54 </ b> R as fulcrums P, and the pressing member 55 hits the lower surface 201 of the field edge 200. Since the field edge 200 is pressed upward, the field edge 200 is press-fitted and fitted into the mounting bracket 300.
[0006]
As described above, when the field edge fixture 50 is used, the lever principle works, so that the field edge 200 can be easily fitted to the mounting bracket 300 without requiring a large force. Further, since the field edge 200 can be attached through the long handle 53, the work can be performed without using an action table such as a stepladder.

[0008]
[Problems to be solved by the invention]
However, the field fitting 50 has the following problems.
First, as shown in FIG. 7, the pressing member 55 is a flat rectangular material and is fixed to the handle 53. Therefore, when the handle 53 is pulled up to the near side, the pressing member 55 is lined with the lower surface 201 of the field edge 200. There is a problem that the lower surface 201 of the field edge 200 may be deformed, for example, because the contact and the force concentrate on the contact surface. Since the deformed field edge 200 becomes unsightly, it has to be replaced, which is troublesome and expensive.
[0009]
Further, since the pressing member 55 and the field edge 200 are engaged, and the upward movement associated with the circular motion around the fulcrum P of the pressing member 55 is also generated, a lateral movement is slightly generated. There is a problem that it may be moved in the axial direction by being pulled by the pressing member 55. Therefore, it is necessary to return the moved field edge 200 to the original position, which is troublesome.
[0010]
Further, as shown in FIG. 8, in the field edge fitting 50, since both limb pieces 52L and 52R are also flat bars, when the installation interval between two adjacent field edges 200 is narrow or when the field edge 200 is on the wall side. When it is provided, there is a problem that it cannot be used.
[0011]
The present invention has been made in view of the above problems, and allows the field edge to be attached to the field edge holder without deforming the field edge, and suppresses the movement of the field edge in the axial direction at the time of attachment. It is an object to provide a field fitting that can be used.
[0012]
[Means for Solving the Problems]
The field edge fitting according to claim 1 of the present invention, which has been made to achieve the above object, is a hook member that is hooked to a field edge holder attached to a ceiling at a distal end portion of a long handle. A pressing member that presses a field edge arranged to be orthogonal to the field receiver below the field receiver in a state in which the hook member is hooked on the field receiver; In the field edge fixture, the hook member has a pair of thin plate-like hook plates facing each other with a gap slightly larger than the width of the field edge, and the handle on the upper end portion of the hook plate.

A pair of projecting portions 7L and 7R projecting in a substantially orthogonal direction is provided. The installation interval between the pair of hooking plates 6L and 6R is set to be slightly larger than the width of the field edge 200 in order to easily sandwich the field edge 200. Further, the bottom plate 8 is provided at the lower end portion between the pair of hook plates 6L and 6R, and the tip end portion of the handle 2 is fixed to the center portion of the bottom surface of the bottom plate 8, so that it is hooked right above the handle 2. The member 3 will be located, and the space-saving fixture 1 can be saved.
[0018]
As shown in FIG. 1, FIG. 3, or FIG. 4, the pressing member 4 includes a rotating shaft 9 that is rotatably provided at a lower end portion between the pair of hooking plates 6 </ b> L and 6 </ b> R, And a pressing plate 10 in contact with the lower surface 201 of the edge 200.
The pressing plate 10 is a quadrangular plate having a size substantially equal to the bottom plate 8 of the hooking member 3, and the rotation center 10 </ b> C is shifted in the opposite direction to the pair of protrusions 7 </ b> L and 7 </ b> R of the hooking member 3. Is fixed, and the end portion 11 on the protruding portion side is brought into contact with the bottom plate 8 of the hooking member 3 by its own weight, and the upper surface 12 is inclined toward the protruding portion side. The vertical distance between the pair of protrusions 7L, 7R of the hook member 3 and the rotation center 10C of the pressing plate 10 is larger than the distance from the upper surface 101 of the field edge receiver 100 to the lower surface 201 of the field edge 200 after mounting, The pair of projecting portions 7L and 7R of the hooking member 3 are easily hooked to the field receiver 100. The upper surface 12 is preferably smoothed to reduce friction with the field edge 200.
In the present embodiment, the rotating shaft 9 is composed of a fixed shaft 9A and a tubular body 9B that is rotatably mounted on the fixed shaft 9A, and the pressing plate 10 is fixed to the tubular body 9B. It is not limited to this.
[0019]
Attachment of the field edge 200 to the field edge receiver 100 using the field edge attachment 1 having the above-described configuration is performed according to the following procedure.
First, as shown in FIGS. 2 and 3, both ends of a long field edge 200 are attached to a mounting bracket 300 fixed at a predetermined interval to a field receiver 100 attached to the ceiling by any means. Attach, and temporarily fix the field edge 100 so that the field edge 200 is orthogonal to the field edge receiver 100 below the field edge receiver 100. At this time, the middle portion of the field edge 200 is located just below the mounting bracket 300 but is not yet fitted and is slightly bent.
Next, as shown in FIG. 3, the pair of protrusions 7L and 7R are gripped so as to face forward, the field edge fixture 1 is lifted, and the field edge 200 is sandwiched between the pair of hooking plates 6L and 6R. The pair of protrusions 7L and 7R are hooked on the upper surface 101 of the field edge 100 so that the tip end of the handle 2 is tilted slightly forward, and as shown in FIG. The pressing plate 10 is rotated until it contacts the lower surface 201 of the edge 200, and the upper surface 12 is brought into surface contact with the lower surface 201 of the field edge 200.
[0020]
In this state, as shown in FIGS. 4 and 5, when the handle 2 is pulled up to the near side, the field edge fixture 1 uses the contact point between the pair of hooking plates 6L and 6R and the field edge receiver 100 as a fulcrum P. The pressing plate 10 presses the field edge 200 upward. As a result, the field edge 200 is press-fitted into the mounting bracket 300, the clamping piece 301 of the mounting bracket 300 engages with the recess 202 of the field edge 200, and the field edge 200 is fitted into the mounting bracket 300.
At this time, as shown in FIG. 4, the handle 2 and the hooking member 3 rotate around the fulcrum P, but the pressing plate 10 is rotatable with respect to the hooking member 3 and is in a state where a force is applied. Thus, since the surface is smoothly in surface contact with the lower surface 201 of the field edge 200, it does not rotate with the handle 2 and the hooking member 3, and slides to the near side while being in surface contact with the lower surface 201 of the field edge 200.
[0021]
As described above, the field edge 200 can be attached to the field edge receiver 100 via the plurality of attachment members 300 by sequentially fitting the attachment member 300 and the field edge 200 in the intermediate portion.
[0022]
If the field edge fixture 1 is used, as shown in FIGS. 3 and 4, the field edge 200 is attached to the pressing plate 10 by simply hooking the hook member 3 on the field edge receiver 100 and pulling the handle 2 forward. It is pressed and fitted to the mounting bracket 300. When the handle 2 is pulled up, the pressing plate 10 slides while maintaining the state of surface contact with the lower surface 201 of the field edge 200, so that the load does not concentrate on the contact surface. Therefore, the lower surface 201 of the field edge 200 is not deformed such as a dent, and the field edge 200 is not engaged with the pressing plate 10 and pulled in the axial direction.
[0023]
Further, as shown in FIG. 5, the field edge fixture 1 includes a pair of hooking plates 6 </ b> L and 6 </ b> R of the hooking member 3 formed of thin plates, so that the installation interval between two adjacent field edges 200 is set. Can also be used when the width is narrow or when the field edge 200 is provided near the wall.
[0024]
Further, as shown in FIG. 3, the rotation center 10 </ b> C of the pressing plate 10 is displaced in the opposite direction to the pair of protrusions 7 </ b> L and 7 </ b> R of the hooking member 3 and is fixed to the rotation shaft 9. Since the end 11 on the protruding portion side of the pressing plate 10 contacts the bottom plate 8 due to its unbalanced weight, the upper surface 12 of the upper edge 12 The pair of protrusions 7L and 7R naturally return to the inclined state. As a result, the work can be performed while the field edge fixture 1 is lifted, and the work speed can be increased.
[0025]
【The invention's effect】
As described above, according to the field edge fixture of claim 1 of the present invention, since the pressing member is rotatable, the contact area with the lower surface of the field edge can be increased, and this contact surface There is an advantage that it is possible to prevent the force from being concentrated on the surface and to prevent the lower surface of the field edge from being deformed, for example, to be recessed.
[0026]
Further, since the pressing plate slides along the lower surface of the field edge, there is an advantage that the field edge is not pulled in the axial direction.
As a result, it is possible to save the trouble of replacing the field edge, and there is an advantage that the workability can be improved and the cost can be reduced.
[0027]
Furthermore, since the hooking plate of the hooking member has a thin plate shape, it can be used even when the installation interval between two adjacent field edges is narrow or when the field edges are provided at the wall. There is.
[0028]
According to the field fitting of the second aspect, the hook member is positioned directly above the handle, and there is an advantage that the space of the field fitting can be saved.
[0029]
According to the field edge fixture according to claim 3, only by removing the field edge mount from the field edge receiver and the field edge, the upper surface of the pressing plate is inclined to the protruding portion side due to its unbalanced weight. Since the state naturally returns to the state, the work can be performed while the field edge fixture is lifted, and workability can be improved.
