Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel retainer, and more particularly, to a panel or a civil engineering structure such as a dam, a pier, a bridge girder, a revetment, a retaining wall, or an exterior of a building structure. The present invention relates to a simple holding device suitable for holding a panel of about 50 kg.

[0002]

2. Description of the Related Art In recent years, civil engineering structures such as dams, piers, bridge girders, seawalls, retaining walls, etc. have been harmonized with natural landscapes, and have become new habitats for living things without destroying ecosystems. Attempts have been made to cover the surface of the concrete structure with a panel that has been removed. The panels are made of a material that absorbs moisture and is highly moisturizing and water-permeable. The panels are porous or hollow so that microorganisms can inhabit, and natural stones such as lava are stuck on the surface. There are also things.

[0003] Such a panel is, for example, 1 m long.
It is made to have an appropriate size of about ² and is attached side by side to the surface of the concrete structure with an adhesive or the like, or is fixed with an anchor bolt.

[0004]

However, the panel needs to be cleaned and replaced. In such a case, the panel must be peeled off from the concrete structure, which is not only complicated, but also may damage the panel.

Accordingly, an object of the present invention is to provide a sufficient holding force without directly attaching or fixing a panel to an object to be mounted, and also to have a guide function for facilitating mounting and replacement of the panel. It is to provide a panel holder.

[0006]

According to the present invention, there is provided a panel holder having an L-shaped insertion-side member and an L-shaped engaging portion for engaging one of the pieces with an attached body. And a fixed-side member having an engaging portion that engages with the other piece so that one of the insertion-side members can be freely inserted and removed.

In the panel holder of the present invention, one piece of the fixed side member is locked to the body to be mounted, and the other piece of the fixed side member mounts the panel, and With one piece inserted into the engaging portion of the fixed side member,
The other piece of the insertion-side member contacts the surface of the panel and holds the panel.

For example, with the insertion-side member positioned at the lower end of the panel, one piece of the insertion-side member is inserted into the engaging portion of the other piece of the fixed-side member that is locked to the attached body. Then, when the panel is pushed in, the panel is guided on the other piece of the fixed side member, and is received by one piece of the fixed member. When an external force is applied to the panel in the direction of dropping from the panel holder, the panel presses the other side of the insertion side member outward, and the moment generated on the other side of the insertion side member secures the insertion side member. It works hard to come off the installation member. Therefore, the panel is prevented from falling off. When replacing the panel, if the panel is lifted from the panel holder and separated from the attached body, the insertion-side member is released from engagement with the fixed member, so that the insertion-side member can be easily removed. It can be detached from the fixed member. Therefore, the panel can be pulled out and removed.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The panel holder of the present invention comprises a dam,
The weight per piece used as an exterior of civil engineering structures such as piers, bridge girders, seawalls, retaining walls, etc. or building structures, etc. is 50 kg.
Suitable for holding panels of a degree, but not limited to those panels.

The panel holder is preferably made of a material having high rigidity and low rust, such as stainless steel. However, depending on the material, weight, and installation location of the panel,
Other metals, synthetic resins and the like may be used. The thickness of each member in the holder is appropriately set according to the weight of the panel.
In order to hold it in place, it is 2 mm or more, preferably 3 to 4 mm in the case of stainless steel.

One or a plurality of holes as locking portions are formed in one piece of the fixed side member of the panel holder in accordance with the supporting strength. In addition to the holes through which fasteners such as nails and screws are inserted, the locking portion is formed by a hook-like portion which is formed by bending one end of the one end and hooking the same to the object. Various modes can be adopted. When one surface of the fixed member does not sufficiently contact the surface of the fixed member when the surface of the fixed member is rough, the gap between one of the fixed member and the surface of the fixed member may be reduced. A cushion material may be interposed.

An engaging portion for engaging one of the insertion-side members with the other of the fixed-side members of the panel holding tool so as to be able to be freely inserted and removed is provided with one of the insertion-side members in the vertical and lateral directions. Any shape may be used as long as it is constrained to the side. Therefore, the tongue piece extending laterally in the engaging portion does not necessarily completely surround one piece of the insertion-side member, and slidably holds both side edges of one piece of the insertion-side member. Any shape is acceptable.

The relationship between the engaging portion of the fixed member of the panel holder and one piece of the insertion member is such that the one piece of the inserting member is engaged with the engaging portion of the fixed member. It is preferable that the engagement is weak when the gravity of the panel is not applied to the panel holder, and the engagement is strong when the gravity of the panel is applied to the panel holder. For example, by bending the tip of one piece of the insertion-side member upward, or forming the angle between one piece and the other piece of the insertion-side member slightly smaller than 90 degrees, the gravity of the panel is reduced. Thereby, it is preferable that the insertion-side member is hardly removed from the fixed-side member.

[0014]

FIG. 1 shows an example in which the panel holder of the present invention is applied to an exterior panel of a concrete retaining wall laid on a seawall such as a river.

This panel 1 is formed by extruding a mixture of cement and silica sand into a hollow structure under a pressure lower than the atmospheric pressure, and steam-curing at a high temperature and a high pressure to obtain a dense tobermorite crystal having a size of about 1 m in length and width. This is a unit of extruded plate, and lava la cut on the surface is stuck with adhesive. In the hollow portion 1b, a bag made of Japanese paper is filled with a high-absorbent polymer resin 2 for hydrolysis of a cellulose-acrylonitrile grout polymer.

This panel is attached to the concrete retaining wall 3 by the panel holder A and the leaf spring B shown in FIG.

The panel holder A is composed of a fixed member 10 and an insertion member 20.

The fixed side member 10 is formed by bending a stainless steel plate into an L-shape and inserting a nail (hole-in anchor) 4 into one piece 11 for engaging the concrete retaining wall 3 with a hole 1.
