Nail protection plate

Abstract

To provide a nail-driving protection plate that can prevent nails from falling into through holes in the vertical direction with a simple and highly durable structure. [Solution] The nail-driving protection plate 11 is formed by bending a metal plate into a semi-cylindrical shape. The nail-driving protection plate 11 has an outer diameter slightly smaller than the inner diameter of the through-hole 102a of the horizontal member 102. At one end of the nail-driving protection plate 11, an arm portion 11a is provided by extending each of the circumferential edges in a rectangular flat plate shape in the tangential direction of the cylinder. The nail-driving protection plate 11 is inserted into the through-hole 102a of the horizontal member 102 from the upper opening with the other end, and the arm portion 11a at one end abuts against the upper opening edge of the through-hole 102a, preventing it from falling into the through-hole 102a.

Description

Technical Field

[0001] The present invention relates to a nail-striking protection plate used to protect a water supply and hot water supply pipe disposed in a through-hole on the back side of a wall from nails, screws, etc. driven from the front side of the wall.

Background Art

[0002] The nail-striking protection plate (protective material for strips) disclosed in Patent Document 1 (see FIG. 4) is composed of a semi-cylindrical metal member, and at one end, folded-back pieces folded outward are provided at both circumferential edges. The nail-striking protection plate is inserted into a vertically formed through-hole on the back side of the wall, for example, to protect a water supply and hot water supply pipe also inserted into the through-hole from nails, screws, etc. driven from the front side of the wall. The nail-striking protection plate is prevented from falling into the through-hole by locking the folded-back pieces to the upper opening edge of the through-hole.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the nail-striking protection plate, the process of folding the folded-back pieces is troublesome, and there is a problem that the durability of the folded portion is reduced.

[0005] An object of the present invention is to provide a nail-striking protection plate that can prevent falling into a vertically formed through-hole with a simple and durable structure.

Means for Solving the Problems

[0006] To achieve the above objective, the invention of claim 1 is a nail-driving protection plate that is inserted into a vertical through hole to protect a long body inserted into the through hole from being driven in with nails, screws, etc., and is semi-cylindrical in shape, with flat arm portions extending from each of the circumferential edges at one end in the direction tangential to the circle of the cylinder, and the arm portions abut against the upper opening edge of the through hole, thereby preventing the nail-driving protection plate from falling into the through hole.

[Figure 8] This is a right-side view illustrating the usage of the nail-driving protection plate, showing the through-holes in a vertical cross-section. [Modes for carrying out the invention]

[0008] The following describes one embodiment of the present invention applied to a nail-proofing plate used in water supply and hot water supply piping (long sections).

[0009] As shown in Figures 7 and 8, a through-hole 102a is formed in the horizontal member 102 located on the back side of the building wall 101 (upper side in Figure 7 and right side in Figure 8). A pipe P, which constitutes a water supply and hot water supply piping (long section), passes through the through-hole 102a, which has a circular cross-section. On the front side of the wall 101 in the through-hole 102a (lower side in Figure 7 and left side in Figure 8), a nail-driving protection plate 11 is inserted to protect the pipe P from nails, screws, etc., driven from the front side of the wall 101 into the horizontal member 102.

[0010] As shown in Figures 1 to 6, the nail-driving protection plate 11 is formed, for example, by bending a metal plate into a semi-cylindrical shape. The nail-driving protection plate 11 has an outer diameter slightly smaller than the inner diameter of the through-hole 102a of the horizontal member 102, and can be elastically deformed to conform to the outer shape of the pipe P. An arm portion 11a is provided at one end of the nail-driving protection plate 11 by extending each of the circumferential edges in a rectangular flat plate shape in the tangential direction of the cylinder.

[0011] A through hole 11b is formed at the tip of one of the arm portions 11a. The through hole 11b is for attaching a hanging bracket (not shown) to the surface of the nail-driving protective plate 11 when plating it using a hooking method.

[0012] As shown in Figures 7 and 8, the nail-driving protective plate 11 is inserted into the through-hole 102a of the horizontal member 102 from the upper opening with its other end, and the arm portion 11a at one end abuts against the upper opening edge of the through-hole 102a, thereby preventing it from falling into the through-hole 102a.

[0013] In this configuration, where the arm portion 11a extends in a flat shape in the tangential direction of the cylinder to prevent the material from falling into the through hole 102a, there is no need for troublesome folding processing, such as in the technology of Reference Document 1 (folded piece), and there is no folded part which tends to reduce durability.

[0014] Furthermore, a pair of notches 11c are formed on each side edge of the nail-driving protection plate 11. Each pair of notches 11c is used as a guide for the cable ties B when fastening the nail-driving protection plate 11 and the pipe P together with the cable ties B.

[0015] (Another example) The above embodiment can be modified, for example, as follows: ○ The arm portion 11a is formed by extending it in a triangular or semicircular flat shape in the tangential direction of the cylinder's circle.

[0016] 〇Deleting the through hole 11b.

[0017] 〇Deleting the notch 11c.

[0018] 〇The "semicylindrical shape" related to the nail - driving protection plate 11 includes the range from 1 / 5 of a cylinder to 4 / 5 of a cylinder, preferably the range from 1 / 4 of a cylinder to 3 / 4 of a cylinder, and more preferably the range from 1 / 3 of a cylinder to 2 / 3 of a cylinder, which can achieve the compatibility of the protection against driving in nails, screws, etc. and the ease of insertion into the through - hole 102a in a high - dimensional manner.

[0019] (Supplementary Note) Regarding the technical idea that can be grasped from the above - mentioned embodiment, the nail - driving protection plate according to claim 1, wherein the semi - cylindrical shape is from 1 / 5 of a cylinder to 4 / 5 of a cylinder.

Claims

[Claim 1] A nail-driving protection plate, which is inserted into a vertical through-hole to protect a long body inserted into the through-hole from being driven in by nails, screws, etc., is semi-cylindrical in shape, and at one end, flat arm portions extend from each of the circumferential edges in the direction tangential to the circle of the cylinder, and the nail-driving protection plate is prevented from falling into the through-hole by the arm portions abutting against the upper opening edge of the through-hole.
