  By the way, in the temporary fence installation site, a temporary fence of about 2 to 3 m in height is usually set up by a small number of people using a support pipe (for example, a steel pipe of φ48.6 cm) as a framework. In this work, since an operator gets on the support pipe and fixes the temporary enclosure, in consideration of safety, it is desirable that the use of a tool or the like is minimized and the handled product is lightweight. However, as a matter of fact, when using a fixing bracket as shown in the background art described above, even with a work assistant, the fixing bracket is held with one hand and the work tool ( It is inappropriate work such as holding a power tool. In addition, since the fixing method is performed only by the operator's sense by screw tightening, it has also caused causes such as falling off due to loosening, deformation of the temporary enclosure steel plate and fixing bracket.

  The present invention pays attention to the above points, and can fix and release the fixing of the panel and the support pipe such as the temporary enclosure steel plate and the like with no work tool with good workability, and fixing with the optimum fixing force. , It is an object of the present invention to provide a panel fixing bracket capable of preventing loosening and falling off after fixing.

The present invention is for fixing a panel having a folded portion formed substantially parallel to the panel body at a side end of the panel body so that the extending direction of the folded portion is substantially orthogonal to the support pipe. It is a panel fixing bracket, and is formed of an elastic rod-like body as a whole, and has a substantially U-shaped portion that engages with the support pipe, and at both ends of the substantially U-shaped portion, the support pipe and a fitting body nipping portion is formed by bending sandwiching in fold-back portion of the panel between the a pair of side surfaces, it is formed in a substantially U-shaped cross-section consisting of other plane substantially orthogonal to the pair of side surfaces And a lever portion provided with a hole through which the metal fitting main body can pass through the pair of side surfaces, and a hole provided in the pair of side surfaces of the lever portion in a fixed state of the panel and the support pipe, Extension of the support pipe And long holes extending in the same direction, and, before and after rotation of the lever portion, the fulcrum distance changes position between said support pipe of the rotating, characterized in that the formation of the slot .

  Hereinafter, the form for implementing this invention is demonstrated in detail based on an Example.

  First, Embodiment 1 of the present invention will be described with reference to FIGS. In the present embodiment, the panel fixing bracket of the present invention is applied to a case where a temporary enclosure steel plate installed at a construction site or the like is fixed to a framework constituted by a support pipe such as a steel pipe. FIG. 1 is an external perspective view showing a fixed state of a temporary enclosing steel plate and a support pipe by the panel fixing bracket of this embodiment, and FIGS. 2A to 2C are views showing the operation of this embodiment. It is the top view which looked at the said FIG. 1 from the arrow F1 direction. FIG. 2D is a diagram showing a modification of this embodiment. As shown in FIG. 1, the temporary enclosure steel plate 40 has a bent portion 42 </ b> A that is substantially orthogonal to the panel body and a folded portion 42 </ b> B that is substantially parallel to the panel body continuously formed on both side ends. In the example, the bent portions 42 </ b> A at the side end portions of the two temporarily enclosed steel plates 40 are installed in a state of abutting each other. The panel fixing bracket 10 of this embodiment is for fixing the temporary enclosure steel plate 40 so that the extending direction of the folded portion 42B is substantially orthogonal to the support pipe 30.

  The panel fixing bracket 10 includes a bracket main body 12 and a lever portion 14. The metal fitting body 12 has a substantially U-shaped portion that can be engaged with the support pipe 30, and has sandwiched portions 12 </ b> A that are bent at both ends of the substantially U-shaped portion. The sandwiching portion 12A is capable of contacting the folded portion 42B, and sandwiches the folded portion 42B between the temporary enclosing steel plate 40 and the support pipe 30 in a fixed state. The metal fitting body 12 is formed of an elastic rod-like body (for example, a metal round bar).

  The lever portion 14 is formed in a substantially U-shaped cross section by an upper surface 16 and a pair of side surfaces 20 and 24 provided on both sides thereof. A slot 18 is formed in the upper surface 16, and a notch 21 (notch on the side surface 24 side is not shown) for facilitating the operation of the lever portion 14 on the side surfaces 20 and 24. , Has a long hole 22 (the long hole 22 on the side surface 24 side is not shown). The direction in which the long holes 18 and 22 are formed is set so as to substantially match the extending direction of the support pipe 30 in the fixed state of the support pipe 30 and the temporary enclosure steel plate 40 (see FIGS. 2B and 2C). Yes. The elongated hole 18 in the upper surface 16 is for inserting a jig 46 (see FIG. 2B) for locking the panel fixing bracket 10. Further, the metal fitting body 12 passes through the long holes of the side surfaces 20 and 24.

  Here, before the support pipe 30 and the temporary enclosure steel plate 40 are fixed, as shown in FIG. 2A, the lever portion 14 is substantially orthogonal to the support pipe 30, and the fulcrum during rotation is long. It becomes one end 22A side of the hole 22. The position of the elongated hole 22 is set so that the position of the end 22A viewed from the support pipe 30 changes before and after the rotation. That is, the holding portion 12A of the metal fitting body 12 is supported by setting the distance between the long hole end portion 22A, which is a pivot point, and the support pipe 30 to be longer at the completion of the rotation than before the rotation. The temporary enclosing steel plate 40 can be fixed by pulling it toward the pipe 30 and sandwiching the folded portion 42B with the support pipe 30.

  Next, the operation of this embodiment will be described with reference to FIGS. 2A and 2B, only one panel side of the butted portion of the temporary enclosure steel plate 40 is illustrated for easy understanding. First, as shown in FIG. 2 (A), the metal fitting body 12 is attached to the outside of the support pipe 30 in a state where the lever portion 14 is raised (a state substantially orthogonal to the support pipe 30), and the holding portion 12A is supported. The folded portion 42B is arranged between the pipes 30. Next, when the lever portion 14 is rotated as shown by an arrow F2a in FIG. 2A, the distance between the long hole end portion 22A serving as a fulcrum of rotation and the support pipe 30 changes, and FIG. Since it is longer than the state shown in A), the metal fitting body 12 is drawn toward the support pipe 30 and the temporary enclosure steel plate 40 is fixed to the support pipe 30 with an optimum fixing force as shown in FIG. .

In this embodiment, the fixed state can be maintained by the lock mechanism using the long hole 22 after the fixing as described above. After the rotation of the lever portion 14 shown in FIG. 2 (B) is completed, the metal fitting body 12 is located on the end 22A side of the elongated hole 22,
a, pushing the tail part (the right end of the figure) of the lever part 14 in the direction of the arrow F2c, or
b. A jig 46 such as a round bar is inserted into the elongated hole 18 on the upper surface 16 of the lever portion 14 and brought into contact with the end of the bracket body 12 and the elongated hole 18 and moved in the direction indicated by the arrow F2b in FIG. Thus, the lever portion 14 moves in the direction indicated by the arrow F2c and assumes the position shown in FIG. Even if the lever portion 14 is lifted again in the state shown in FIG. 2 (C), there is no room to rotate around the long hole end portion 22B, that is, there is no gap between the folded portion 42B and the support pipe 30. The locked state is maintained. The other temporary enclosing steel plate 40 on the abutting side is also fixed in the same manner, so that the bent portion 42A of the temporary enclosing steel plate 40 is fixed to the support pipe 30 in a state of abutting each other.

  When the fixing of the support pipe 30 and the temporary enclosure steel plate 40 is released, the jig 46 is inserted into the elongated hole 18 in the state shown in FIG. 2 (C) while contacting the elongated hole 18 and the metal fitting body 12. By moving the jig 46 in the direction opposite to the arrow F2b, the lever portion 14 returns to the state shown in FIG. 2B and the lock is released. Thereafter, by raising the lever portion 14, a gap is generated between the support pipe 30 and the temporary enclosure steel plate 40 and the fixation is released.

  As described above, according to the first embodiment, the folded portion 42B at the side end of the temporary enclosure steel plate 40 can be sandwiched between the support pipe 40 and the both ends of the substantially U-shaped portion with which the support pipe 30 can be engaged. A metal body 12 formed of a rod-like body, and a long hole 22 through which the metal body 12 penetrates in a pair of side surfaces 20 and 24. The panel fixing bracket 10 is constituted by the lever portion 14. And since the said long hole 22 was formed in the position where the distance between the rotation fulcrum before and behind rotation of the said lever part 14 and the said support pipe 30 changes, it has the following effects.

(1) Since the temporary enclosure steel plate 40 is fixed to the support pipe 30 only by operating the lever portion 14 without using a work tool, the operator can use both hands, and safety in work can be ensured. In addition, since a tool to be carried at the time of work is not necessary, the burden on the operator can be reduced. Further, since the fixing / releasing can be performed by one operation of the lever portion 14, work efficiency is improved.
(2) Since it is fixed by operating the lever part 14, the optimum fixing force can be obtained no matter who works, and it prevents the deformation and breakage of panels and metal fittings due to overtightening, which is a problem in the conventional technology using bolts. It is possible to prevent loosening and dropping off due to insufficient tightening.
(3) Since the rotation is locked by moving the lever portion 14 along the elongated hole 22 after the lever portion 14 is rotated, it is possible to prevent looseness and unexpected dropout.

(4) Since the bracket body 12 has a three-dimensional structure using an elastic material (such as a metal round bar), a spring effect is obtained against stress from all directions, and dropout or breakage due to loosening occurs. It is possible to cope with wind and vibration at construction sites.
(5) Since the fixed position can be arbitrarily set, it is possible to cope with a plurality of types of temporarily enclosed steel plates from different manufacturers.
(6) Since the panel fixing bracket 10 is composed of the bracket main body 12 using a round bar or the like and the lever portion 14 using a plate material or the like, the weight is reduced, so that work labor and transportation costs can be reduced. it can.

  Next, Embodiment 2 of the present invention will be described with reference to FIG. In addition, the same code | symbol shall be used for the component which is the same as that of Example 1 mentioned above, or respond | corresponds (it is the same also about a following example). FIG. 3A is an external perspective view showing the usage state of the present embodiment, and FIGS. 3B-1 and 2C-1 illustrate the operation of the present embodiment as viewed from the direction of arrow F3a. (B-2) and (C-2) are side views showing the operation of this embodiment when (A) is viewed from the direction of arrow F3b. As shown in FIG. 3A, the panel fixing metal fitting 100 of this embodiment is composed of a metal fitting body 12 and a lever portion 102 similar to those of the first embodiment. The lever portion 102 is formed in a substantially U-shaped cross section by an upper surface 16 having a long hole 18 and a pair of side surfaces 20 and 24 provided on both sides thereof. A notch 21 similar to that in Example 1 is formed.

  Also in this embodiment, a long hole 104 is formed on the side surface 20, and a long hole 106 is formed on the other side surface 24. The direction in which the long holes 104 and 106 are formed is substantially the same as the extending direction of the support pipe 30 in a fixed state of the support pipe 30 and the temporary enclosure steel plate 40. And the convex part 104C, 106C is formed in the side of the substantially intermediate part of the said extension direction of these elongate holes 104, 106, and the center part of the elongate holes 104, 106 is formed by these convex parts 104C, 106C. However, it is narrowed to such an extent that the metal fitting body 12 can pass therethrough.

  Next, the operation of this embodiment will be described. 3 (B-1), (B-2), (C-1), and (C-2), for ease of understanding, only one panel side of the butt portion of the temporary enclosure steel plate 40 is used. Is illustrated. First, as shown by a dotted line in FIG. 3 (B-2), the metal fitting body 12 is attached to the outside of the support pipe 30 with the lever portion 102 raised (in a state substantially orthogonal to the support pipe 30). The folded portion 42B is arranged between the portion 12A and the support pipe 30. Next, when the lever portion 102 is rotated as shown by an arrow F4 in FIG. 3B-2, the elongated hole end portions 104A and 106A serving as fulcrums as well as the support pipe are provided as in the first embodiment. Since the distance to 30 changes and becomes longer than the state before rotation, the metal fitting body 12 is drawn toward the support pipe 30 side, and as shown in FIGS. 3 (B-1) and (B-2), The enclosure steel plate 40 is fixed to the support pipe 30 with an optimal fixing force.

  In the second embodiment, after fixing as described above, as shown by an arrow F5 in FIG. 3 (C-1), the lever portion 102 is twisted to be fixed by the lock mechanism using the long holes 104 and 106. Can be maintained. In the illustrated example, by twisting the lever portion 102 in the direction indicated by the arrow F5, the bracket main body 12 gets over the convex portion 104C of one elongated hole 104, and is one end portion that has been a pivotal point of rotation. It moves from the 104A side to the other end 104B side. Further, on the other long hole 106 side, the metal fitting body 12 remains positioned on the end portion 106A side as a rotation fulcrum. By twisting the lever portion 102 in this way, the metal fitting main body 12 is moved to the right side of the convex portion 104C of one elongated hole 104 and to the left side of the convex portion 106C of the other elongated hole 106 (see FIGS. C-1) and (C-2))). Even if the lever portion 102 is lifted again in such a state, the locked state is maintained because there is no room for rotation with the elongated hole end portions 104B and 106A as fulcrums. The other temporary enclosing steel plate 40 on the abutting side is also fixed in the same manner, so that the bent portion 42A of the temporary enclosing steel plate 40 is fixed to the support pipe 30 in a state of abutting each other.

  When releasing the fixing of the support pipe 30 and the temporary enclosure steel plate 40, the lever portion 102 is twisted in the direction opposite to the arrow F5 in the state shown in FIGS. 102 returns to the state shown in FIGS. 3B-1 and 3B-2, and the lock is released. Thereafter, by raising the lever portion 102, a gap is generated between the support pipe 30 and the temporary enclosure steel plate 40, and the fixation is released. According to the present embodiment, the locked state can be maintained by a simple operation of twisting the lever portion 102. Other basic effects are the same as in the first embodiment.

In addition, this invention is not limited to the Example mentioned above, A various change can be added in the range which does not deviate from the summary of this invention. For example, the following are also included.
(1) The shapes and dimensions shown in the above embodiments are examples, and may be appropriately changed as necessary. For example, like the panel fixing metal fitting 50 shown in FIG. 2D, the spring effect may be further enhanced by making the metal fitting body 52 curved when viewed from the direction orthogonal to the support pipe 30. .
(2) In the above-described embodiment, the butt portion between the temporary enclosure steel plates 40 has been described as an example. However, this is also an example, and the side without the butt portion can be similarly fixed.
(3) The locking mechanism using the long holes 18 and 22 and the jig 46 shown in the first embodiment is also an example, and may be provided as necessary.

(4) In the second embodiment, the rotation is locked by twisting in the direction of arrow F5 in FIG. 3 (C-1), but the twisting direction may be reversed. Also in the second embodiment, similarly to the first embodiment, the lever portion 102 is moved in parallel along the support pipe 30 and the metal fitting body 12 is moved to the long hole end portions 104B and 106B. The locked state may be maintained.
(5) The first embodiment and the second embodiment may be used in combination. For example, one of the butting portions of the temporary enclosure steel plate 40 uses the panel fixture 10 of the first embodiment and the other uses the panel fixture 100 of the second embodiment.
(6) In the above embodiment, the case where the temporary enclosure steel plate 40 installed at a construction site or the like is fixed to the support pipe 30 is described as an example, but this is also an example, and a panel other than the steel plate (for example, made of resin) Panel) may be used. Moreover, the present invention is applicable not only to the installation of temporary enclosure steel plates but also to various uses of construction and civil engineering in addition to the use of fixing plate bodies to pipes.

According to the present invention, the both ends of the substantially U-shaped portion with which the support pipe engages have the sandwiching portions that sandwich the folded portion of the panel side end portion with the support pipe, and the whole is elastic. A panel fixing bracket is constituted by a bracket main body formed of a rod-shaped body having a lever portion having a substantially U-shaped cross section having a hole through which the bracket main body passes on a pair of side surfaces. The holes provided in the pair of side surfaces of the lever portion are elongated holes extending in the same direction as the extension direction of the support pipe in the fixed state of the panel and the support pipe, and before and after the rotation of the lever portion. The elongated hole is formed at a position where the distance between the pivot point and the support pipe changes . Since the panel and the support pipe are fixed with an optimum fixing force with good workability only by operating the lever portion, and the fixing is released, the panel fixing bracket can be used. In particular, it is suitable for the case where a temporary enclosure steel plate is fixed to a framed steel pipe at a construction site or the like.
