It was configured to be tightened and fixed to A.

<Problems to be solved by the invention> Conventional hardware as described above has a large number of parts, and requires manufacturing processes such as forming screw holes in each of these parts, resulting in high manufacturing costs. Furthermore, when installing the conductor, it is necessary to tighten it using small screws that are difficult to handle at the installation site, which has the disadvantage that workability and conductor installation efficiency are extremely poor.

In view of these circumstances, the present invention has been devised to provide a lightning protection conductor mounting hardware that reduces manufacturing costs, eliminates the use of screws, improves workability and construction efficiency, and allows for easy and reliable positioning of the conductor. Be purposeful in what you offer.

<Means for Solving the Problems> In order to achieve the above object, the lightning protection conductor mounting hardware according to the present invention is a hardware that has a substantially rectangular C-shape in side view and has a drop-in storage holding part for the strip conductor. A fitting insertion hole for the building fixing part is provided at the center or approximately the center in the width direction of the bottom wall of the main body, and a pair of guide grooves formed opposite to each other at both ends of the storage holding part in the width direction are provided. A lightning arrester conductor mounting hardware, wherein a lid for preventing a conductor from popping out has protrusions on both ends in the width direction to be fitted, and is configured to be able to be inserted into and removed from the side of the hardware main body, the bottom surface of the projections on the lid. and the upper surface of the bottom wall of the hardware main body opposing thereto, each of an engaging tool and an engaged part that elastically engage with each other when the lid is inserted into the correct position with respect to the hardware main body. It has the structure that it is provided.

<Function> Due to the above-described configuration, after the hardware main body, which is made into one component, is fixed to the building fixing part through the central fixture insertion hole, the operation of dropping the strip conductor and the side of the lid body are performed. The lightning strip conductor can be installed in a predetermined location with a simple and easy manual operation that does not require the use of small screws or tools for screwing them in. In particular, when the lid is inserted from the side by a specified amount, the engaging tool and the engaged portion automatically engage elastically and the insertion position of the lid is fixed and held. This makes it possible to ensure that the body prevents the strip conductor from flying out.

<Examples> Examples of the present invention will be described below in detail based on the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a metal body made of copper or brass, and the side surface forms a conductor storage and holding part 4 that can store and hold a band-shaped conductor 3 such as a copper band by dropping it. The entire structure is approximately H-shaped when viewed from the side, including the approximately C-shaped portion. Reference numeral 5 denotes a plug vault (an example of a fitting) insertion hole formed in the bottom wall portion 2 of the hardware main body 1 (which corresponds to the intermediate wall portion considering the overall shape) at approximately the center position in the width direction thereof. One end of it is plated. Reference numeral 6 denotes an elastic rubber member that is fitted and fixed in a recessed space formed on the back surface of the bottom wall portion 2. In addition to serving as a waterproof packing, this is used to attach the mounting hardware to copper plates, etc., metal plate roofing boards, ridge tiles, etc. It can be effectively used as an adhesion surface when securely and strongly attaching to a surface using an adhesive.
Reference numeral 10 denotes a lid body for pressing the band-shaped conductor 2 housed and held in the metal body 1 from above to prevent vibrations or the conductor 2 from flying out or moving when it is attached to an inclined wall surface. At both ends in the width direction,

Projections 1 that are approximately L-shaped and approximately oppositely L-shaped in side view and fit into the guide grooves 1A, 1A of
0A and 10A are integrally formed, and this protrusion 1
The lid body 10 is configured to be freely inserted into and removed from the side of the hardware main body 1 in a state where the guide grooves 0A and 10A are fitted into the guide grooves 1A and 1A. The lid body 1 is located at the center or approximately the center in the longitudinal direction of the strip conductor 3 at the upper surface of the bottom wall portion 2 of the hardware main body 1, and at the bottom surface of the left and right protrusions 10A, 10A of the lid body 10.
The center or approximately center position in the direction of insertion and removal of 0 is as follows:
As an example of an engaging tool and an engaged part that elastically engage with each other when the lid body 10 is inserted into the hardware main body 1 to the normal position, that is, to the position shown by the solid line in FIG. One of a spring ball 11 and a hemispherical recess 12 as clearly shown in the figure is provided.

For example, as shown in FIGS. 4 and 5, the above-mentioned lightning conductor mounting hardware is attached to a concrete parapet W, which is an example of a building fixed part, while being electrically connected to a lightning rod (not shown). It is used to fix the strip conductor 3 disposed on the parapet W in a fixed position at a plurality of locations appropriately spaced in the longitudinal direction, and the metal body 1 is attached to the plug 7 inserted into the parapet W. The band-shaped conductor 3 is fixed via the plug vault 8 screwed through the insertion hole 5, and in the fixed state, the band-shaped conductor 3 is dropped into the storage holding part 4 and stored, and the lid body 10 is inserted into the hardware body 1 to remove the band-shaped conductor 3. Although not shown in the drawings, if the fixed part of the building is a copper plate, metal plate roof, ridge tile, etc., adhesive may be applied to the exposed surface of the elastic rubber member 6 to fix the mounting hardware. Measures will be taken to
