Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a panel connecting jig capable of easily connecting various panels such as a retaining panel and a concrete form panel.

[0002]

[Prior art]

 As a means of retaining soil in the excavation work for sewerage and the like, a simple retaining method is known in which panels are penetrated into the ground while excavating between the panels while supporting the opposing panels with cutting beams.

In this type of construction method, it is necessary to connect the upper and lower panels to form a single plate body. Conventionally, as shown in FIG. 3, a convex portion c is formed on the lower side of each of the panels a and b. At the same time, a concave portion d capable of fitting with the convex portion c is formed on the upper side thereof, and a plurality of insertion holes e and bolt holes f are respectively provided on the side surfaces of the convex portion c and the concave portion d to be fitted. It is connected by screwing.

[0004]

[Problems to be solved by the invention]

 In the method of connecting the panels a and b with the bolts g, at least three places between the adjacent panels a and b must be bolted, and the bolting operation and the removing operation are performed. This requires a lot of time and effort, and there is a need for proposals for improvements.

Further, since the bottle hole f is exposed, there is a problem that earth and sand are easily attached or damaged, and the bolt g is easily screwed.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a panel connecting jig which can be connected or disconnected by a simple operation. is there. Still another object of the present invention is to provide a panel connecting jig which is hardly damaged and has excellent durability.

[0007]

[Means for Solving the Problems]

 The invention according to claim 1 is a panel connecting jig for connecting between adjacent panel flanges, wherein the grip body has a U-shape and has a holding opening for holding between the panel flanges; A panel connecting jig comprising a connecting pin penetrating between panel flanges.

According to a second aspect of the present invention, there is provided the panel connecting jig according to the first aspect, wherein the grip body has a U-shape in which the upper jaw and the lower jaw are connected at the back, and an opening for holding between the two jaws. This is a panel connecting jig characterized by forming pin holes in both jaws.

According to a third aspect of the present invention, in the panel connecting jig according to the first or second aspect, the holding opening is set substantially equal to the thickness of the flange of the panel to be connected. A panel connecting jig characterized by the above-mentioned.

[0010]

[Embodiment of the invention]

 An embodiment of the present invention will be described below with reference to FIGS.

<A> Panel Structure The panel 10 includes a rectangular skin plate 11 and a flange 12 provided upright on the periphery of the skin plate 11.

A plurality of holes 13 are formed in a flange 12 of each panel 10 to be joined. When the panel 10 is built by engaging with a column or the like, a known engaging element is provided on the left and right side end surfaces of the panel 10.

<B> Structure of Panel Connecting Jig The panel connecting jig includes a U-shaped grip body 20 and a connecting pin 21 for connecting the grip body 20 to the panel 10.

The grip body 20 is configured by connecting an upper jaw 22 and a lower jaw 23 with a back 24. A holding opening 25 is formed between the upper jaw 22 and the lower jaw 23. The holding opening 25 is set substantially equal to the plate thickness of the flanges 12 of the panels 10 to be connected. This is to eliminate rattling between the panel 10 and the grip body 20. The jaws 22 and 23 are provided with pin holes 26 and 27 through which the connecting pin 21 can be inserted.

In the drawing, reference numeral 28 denotes a reinforcing rib, which is formed so as to protrude from the outer surfaces of the jaws 22 and 23 and the back 24.

[0016]

[Action]

 Next, a method of using the panel connecting jig will be described.

<A> Linking Operation As shown in FIG. 1, the upper panel 10 is placed above the lower panel 10 so as to overlap. As a result, the upper flange 12 of the lower panel 10 and the lower flange 12 of the upper panel 10 are in contact with each other.

Next, the holding opening 25 of the grip body 20 is provided on both flanges 12, 12. At this time, the pin holes 26 and 27 of the grip body 20 are aligned with the holes 13 of the flanges 12 and 12.

Then, the connecting pin 21 is inserted into the holes 26, 13, 13, and 27 located on the same line to complete the connecting operation. FIG. 2 shows a state after the connection is completed.

When a vertical separating force acts between the panels 10, 10, the separating force is supported by the rigidity of the grip body 20. When a horizontal moving force acts between the panels 10, 10, the moving force is restricted by the shear strength of the connecting pin 21.

In order to prevent the connection pin 21 from coming off, a through-hole 29 may be formed at the end of the connection pin 21 and a known removal prevention pin may be attached. In order to set the panel connecting jig in this way, it is sufficient to simply insert the connecting pin 21 after the grip body 20 is externally mounted on the flanges 12 and 12.

<B> Disconnection Operation To release the connection between the panels 10, 10, an operation reverse to the connection operation is performed.

That is, when the grip body 20 is removed from the flanges 12 after the connection pins 21 are removed, the connection between the panels 10 and 10 is released.

[0024]

[Effect of the invention]

 The present invention has the following effects.

<B> The grip body can be connected by simply inserting the grip body between the flanges of the adjacent panels and inserting the connecting pin. To release the connection, pull out the connecting pin and then remove the grip body from the flange. Just remove it. Therefore, the panel connecting jig according to the present invention can easily and easily perform the panel connecting and disconnecting operations.

<B> It is only necessary to form a pin hole in the panel or the grip body, and it is superior in terms of workability and durability as compared with the conventional connection technology for forming screws.

<C> By simply performing a simple process of forming a hole in the flange of the panel, it can be applied to various panels of different existing manufacturers, and is versatile.

<D> When the panel is an earth retaining panel, prompt workability of connection is required. However, the panel connecting jig according to the present invention can surely satisfy such a demand, and Ideal as a panel connector.

<E> Since the grip body has a simple structure, it is possible to provide a panel connecting jig which is excellent in manufacturability and low in cost.
