Description

[Detailed description of the invention] This invention is one of the components of lightning rod equipment, and is a lightning conductor installed along the wall of a building, for example, to electrically connect the lightning rod prong and the ground electrode. The conductor is held in a fixed position by a fixed part such as a building wall at multiple locations in the longitudinal direction to prevent the conductor from sagging or shaking due to the influence of wind, or other locations that may occur as a result of these phenomena. It plays the role of preventing the lightning protection function from being dried out or damaged due to catching on objects, or from uncertainties or significant deterioration of the lightning protection function due to defective conductors. The present invention relates to a lightning conductor mounting hardware which has a conductor holding part that can be tightened and fixed in a state of insertion, and has a threaded part for screwing into the fixing part on the other end side of the hardware main body.

In this kind of hardware that has been generally known in the past, for example, the so-called so-called hardware is used to fix the hardware to the wall by screwing the male thread into a plug embedded in the concrete wall of a concrete building. In the case of an exposed type, in order to prevent rainwater, etc. from entering the concrete wall through the internal space of the buried plug and the gaps around the plug, the mounting seat of the hardware body and the external surface of the concrete wall. A method was adopted in which a washer with waterproof packing separate from the main body of the hardware was sandwiched between the parts, but as mentioned above, the washer only had the function of preventing rainwater from entering. It is used only for the purpose of achieving the The seat portion and the washer only make surface contact, and if the precision of the contact surface is poor due to distortion of the washer, rainwater, etc. may enter the internal space of the plug through the gap between the two. The drawback was that it did not provide a reliable and sufficient water intrusion prevention function.

In view of the above circumstances, the present invention has an object to provide a lightning conductor mounting hardware that not only ensures the function of preventing water intrusion from the mounting part, but also allows for strong mounting and expansion of the mounting area.

In order to achieve the above object, the lightning conductor mounting hardware according to the present invention has the above-mentioned configuration, and a waterproof elastic packing is fitted and held around the threaded portion at the mounting seat of the hardware body. It has a characteristic structure and has achieved the following effects.

In other words, instead of making the waterproof elastic packing separate from the hardware main body, by fitting and holding the waterproof elastic packing into the mounting seat of the main body to substantially integrate the hardware main body and the waterproof packing, it is possible to When screwing to a fixed part such as a wall, there is no need to put a washer with a packing on each piece, making it easier to work with.In addition, the packing and the mounting seat are in elastic contact and have a labyrinth effect. It is possible to reliably achieve the effect of preventing rainwater from entering between the outer surface of the fixed part such as a wall and the hardware body. Moreover, by interposing an adhesive between the elastic packing and the outer surface of the fixing part such as a wall, the fixing part and the hardware main body can be attached extremely firmly together with the tightening and fixing by the screw part. In addition, even if the fixed part cannot be tightened and fixed using a threaded part, it can be firmly mounted by using the above-mentioned adhesive mounting method, making it suitable for use with the hardware. This has led to practical effects such as expansion of space and improved versatility.

Embodiments of the present invention will be described in detail below based on the drawings.

Figures 1 and 2 are examples of construction of lightning rod equipment,
is a reinforced concrete building with a flat roof and a tower Y, and a lightning rod prong N is attached to the upper end of a support pipe P that is vertically installed along the inner wall surface of the tower Y.
are screwed together. A is a lightning conductor physically and electrically connected to the lightning conductor N, which is suspended along the outside of the support pipe P and is arranged along the parapet around the building X, Furthermore, it hangs down along the outer wall of building X and is connected to ground electrode B buried underground.

Then, hardware E for fixing the lightning conductor A, which is arranged and hung vertically along the parapet and outer wall of the building X, to the building X at multiple positions in the longitudinal direction is installed as follows. It is configured.

As clearly shown in FIGS. 3 to 5, the flat plate-like portion 1
In the hardware main body 1, which is made of brass and plated with chrome and has a disk-shaped mounting seat part 1A, a flat plate part 1B is provided with a flat plate part 1B on the side opposite to the side where the mounting seat part 1A is present. A member 2A is attached via bolts and nuts 5 to the folded portion of the metal band plate, which forms a substantially cylindrical conductor holding portion 2 through which the conductor A can be inserted and fastened. A male threaded portion 3 for screwing is fixedly protruded from the center of the bottom surface of the mounting seat portion 1A, and a recess 1a concentric therewith is provided on the bottom surface side of the mounting seat portion 1A.
A protrusion 4 is formed and elastically fits into the recess 1a.
A waterproof elastic packing 4 having an outer diameter approximately equal to that of the mounting seat portion 1A is attached to the protruding portion 4A.
is fitted into the recess 1a, and the mounting seat 1 is inserted into the recess 1a.
The mounting hardware E is fixedly held to the recess 1a of the projection 4A through an adhesive or without using an adhesive through elastic adhesion to the recess 1a of the protrusion 4A. As shown in the figure, the male threaded portion 3 is screwed into a split plug D buried in a concrete wall C, which is an example of a fixed portion, to be fixedly attached to the wall C, and the elastic packing 4 By adhering the plug to the outer surface of the concrete wall C and fixing it with an adhesive if necessary, it is possible to prevent rainwater, etc. from entering the split plug D and its surroundings, and increase the strength of the installation to the wall C. The mounting hardware E installed in this way
The conductive wire A is inserted into the holding portion 2 of the holder 2 and is tightened and fixed. Although not shown in the drawings, when the above-mentioned mounting bracket is used by being attached to a metal roof or the like that cannot be screwed in and fixed using the male threaded portion 3, the mounting surface of the elastic packing 4 is fixed with an adhesive. It should be installed and used.

Another embodiment will be described below.

[] The one shown in FIGS. 8 and 9 is a hardware E' in which a female threaded part 3 for screwing is formed on the mounting hardware main body 1, and the other parts have the same configuration as the above embodiment. The lightning conductor A hanging down along the support pipe P shown in Fig. 1 is connected to the support pipe P at multiple positions in the longitudinal direction (vertical direction).
It is used when supporting the
To explain its usage in detail, as shown in FIGS. 10 and 11, the elastic packing is attached to the outer surface of a substantially U-shaped saddle 7 fixedly attached to the support tube P via a tightening band C. 4, and by screwing the bolt 8 into the female threaded portion 3, the hardware is attached to the saddle 7, and in that state, the conductor A is inserted into the holding portion 2 and tightened and fixed. By adhering and fixing the packing 4 to the outer surface of the saddle 7 with an adhesive, a strong attachment can be expected.

[] The elastic packing 4 made of natural rubber is most suitable for improving the adhesive effect.
