Description

TECHNICAL FIELD The present invention relates to a fixture for fixing wiring or the like to a scaffolding at a construction site. When arranging water hoses used for watering to prevent scattering of dust, etc., these flexible long objects can be easily installed on scaffolds made of single pipes, and the work can be done at low cost. The present invention relates to a fixture technology that facilitates installation and further enhances work safety.

BACKGROUND ART At construction sites and civil engineering sites, scaffolding is assembled around the building, and power cords are fixed by a simple method in order to use power tools and lighting. Also, in demolition work, etc., a water hose or the like may be arranged on the scaffold or the like for sprinkling water so as not to cause pride. At such sites, having long cords, hoses, etc. at your feet can lead to accidents and is dangerous. Therefore, in order to ensure the safety, they are often fixed with binding bands, wires, hooks, or the like so as not to interfere with the work. However, wires and binding bands are complicated to install and are uneconomical because they are disposable. Therefore, there is a demand for a fixture that can easily fix a power cord, a water hose, or the like to a single pipe or the like, can be easily removed, and can be used repeatedly. Also, scaffolding is generally covered with a sheet to prevent materials from falling and scattering, but when installing such a sheet, it is necessary to fix it to a single pipe at a predetermined interval and use a string or the like. Since it is fixed, the work is also extremely complicated.
There is also a fixture that hooks onto a single tube pipe with a hook or the like, but if the seat is simply hooked, the hook may come off easily when the seat is shaken by the wind or the like.
Therefore, it can be said that it is more preferable to have a fixture that can easily fix the sheet to the single tube pipe and that simultaneously satisfies the requirement that the sheet does not come off easily when the seat shakes. is none.

In view of the above problems, various techniques have been conventionally proposed. A curing sheet and a fastener used for stretching the curing sheet between the framework scaffolding (see Patent Document 1) have been proposed and become a well-known technique. More specifically, it is a structure that can deal with the unevenness of the distance between the curing sheet and the copper pipe of the framed scaffolding that occurs on site. A connector is provided. Since it is a circular fastener, it is structured so that the seat does not come off due to the shaking of the seat, etc. Since it is necessary to close the joint, the fastening work is complicated, and the above problem has not been solved.

In addition, there has been proposed a support metal fitting for a protective sheet (see Patent Literature 2), which is capable of always arranging hook portions on the same horizontal line even when attached to binding holders of different heights, and has become a well-known technology. More specifically, in the protective sheet support fitting attached to the fastening holder of the strut having fastening positions consisting of first and second fastening holders with different horizontal height positions, the first fastening holder has the same support fitting. When the metal fitting main body is inserted, the eyelet on the side of the protective sheet is inserted into the first hook portion on the lower side. On the other hand, when the metal fitting body is inserted into the second fastening holder, the rotating plate is turned upside down to move the upper second hook portion downward to insert the eyelet on the protective sheet side. be. Since the position of the hook for attaching the seat can always be kept at a constant height, the seat fixing work can be performed smoothly. However, the hooks are simply arc-shaped and cannot prevent the sheet from coming off when it is shaken by the wind or the like. Therefore, the above problem has not yet been solved.

In addition, a locking tool having a hook portion using a locking hole for wedge locking or a locking pocket portion does not require any tightening and holding work unlike a clamp, and is useful for constructing a scaffold. In the same way as wedges, there is an epoch-making locking device for temporary scaffolding (see Patent Literature 3) that allows a hook portion to be provided on a temporary scaffolding by inserting and locking it into an existing locking hole or pocket portion from above. proposed and known in the art. More specifically, "A protective sheet or protective net that hangs down on a temporary scaffold, or a base body provided with a hook for hooking and locking a fall prevention sheet or fall prevention net, to a temporary pipe that crosses the posts of the temporary scaffold. A locking tool for temporary scaffolding provided with a locking fixing portion that is inserted and locked into a locking hole or a locking pocket portion provided around the post into which a provided wedge is inserted and locked. However, although this technology has a structure in which the seat fixture can be easily fixed to the pipe, it cannot prevent the seat from coming off when the seat is shaken by wind or the like because it has a normal hook structure. It does not support holding of . Therefore, the above problem has not yet been solved.

To solve these problems, the present inventor has already invented an arcuate "scaffolding sheet fixture" and obtained a patent (see Patent Document 4). The related technology has the problem of "a scaffolding sheet fixture that can easily fix the sheet to the pipe and is structured so that the sheet does not come off easily when the sheet shakes." It consists of an annular portion which is a missing annular ring having a portion and a guide portion, the annular portion has a loose fitting portion for loosely fitting the pipe inside, and the pipe is fitted to both ends of the missing annular portion. It has a guide part for insertion into the loose fitting part, the guide part protrudes outward from the annular part, and the mutually facing surfaces of the guide part gradually widen from the inside to the outside of the annular part. It has a curved surface, and the ring portion has a seat holding portion that holds a part of the seat by inserting it into a small circle of the ring portion. However, such a scaffolding sheet fixture is not suitable for installation of power supply courts, watering hoses, etc., and it can be said that problems remain. The inventors of the present application have come up with the proposal of the "single tube pipe wiring fixture" in order to solve the remaining problem.

FIG.

A single pipe wiring fixture 1 is composed of an annular portion 2 and a guide portion 3 . The wire fixture 1 for a single tube pipe is generally annular, partly missing, and has a shape similar to the letter C of the alphabet. It is a fixture for fixing a power cord D and the like and a sheet 12 to a single tube pipe 10 in a scaffolding structure such as a construction site. The whole is integrally molded, and is made of resin, has elasticity, and can recover its shape against deformation to some extent. The material may be a uniform material such as plastic, or a structure in which a metal is embedded as a core material. By using the core material, the strength can be further increased. The size is such that the scaffolding single pipe 10 can be loosely fitted inside the single pipe wiring fixture 1 . Since the scaffolding single pipe 10 generally has a diameter of about 48.6 mm, the inner diameter of the annular portion 2 is slightly larger than that, and the thickness of the annular portion 2 is about 7 mm.

The annular portion 2 occupies most of the single-tube pipe wiring fixture 1, is annular, partly missing, and has a shape similar to the letter C of the alphabet. A single pipe 10 is loosely fitted by a loose fitting portion 4 inside the ring portion 2 . Also, the handle 6 is arranged on the outside. The handle 6 may be used when fitting the single pipe wiring fixture 1 to the single pipe 10 or when removing it from the single pipe 10 . In some cases, it also has a function of restricting movement of the seat 12 . Guide portions 3 are arranged at both open ends of the ring portion 2 .

The guide part 3 is a structure for smoothly completing the work when fitting the wiring fixture 1 for a single pipe to the single pipe 10 . The guide portion 3 is located at the open end of the annular portion 2 and protrudes outwardly from the annular portion 2. The surfaces of the guide portion 3 facing each other gradually taper from the inside to the outside of the annular portion 2. It forms a guide surface 301 that is a widening curved surface. By having this guide surface 301, by simply pressing the single pipe pipe wiring fixture 1 against the single pipe 10, the end of the annular portion 2 is opened, and the single pipe 10 can be easily moved inside the annular portion 2. , and can be loosely fitted by the loosely fitting portion 4 .

The loose fitting portion 4 is a hole portion inside the annular portion 2 and inserted through the single tube pipe 10 with a gap. Since a general single pipe has a diameter of 48.6 mm, the diameter of the loose fitting portion 4 is slightly larger than the diameter of the single pipe 10, and is preferably around 50 mm. Considering that the wiring such as the power cord D is sandwiched between the single tube pipes 10, the shape of the loose fitting portion 4 has a long axis in the direction from the guide portion 3 toward the center of the hole of the annular portion 2. An elliptical shape having a minor axis in a direction orthogonal to this is preferable.

Although not shown in the drawings, the sheet holding portion 5 is a portion that holds the work sheet 12 by inserting the sheet guide portion 14 from one end side of the guide portion 3 on one side of the arm from which the annular portion 2 is separated. is.

The handle 6 is provided with a protrusion on the outside of the annular portion 2 that can be easily grasped with a fingertip so that the work of loosely fitting the wire fixture 1 for a single pipe according to the present invention to the single pipe 10 can be done efficiently. By forming the outer diameter shape of the projection to be substantially C-shaped, the hose holding portion 7 can clamp the water hose H for watering or the like.

The hose holding portion 7 is provided on the handle 6 to hold a hose for watering or the like. It is 20 mm, and even in the case of a thick hose with an inner diameter of 18 mm, the outer diameter is approximately 25 mm. In addition, it is not limited to the dimension which concerns, It determines suitably according to the watering hose H to use.

The single pipe 10 is mainly a pipe-shaped steel pipe with a diameter of 48.6 mm, and although there are different types of thicknesses of 1.8 mm and 2.4 mm, the outer diameter is common. It is used for scaffolding at construction sites, etc., and is assembled with dedicated clamp fittings such as a straight type, a universal type, or a continuous type.

Although not shown in the drawings, the sheet 12 is a so-called blue sheet, such as a waterproof laminated sheet made of polyethylene, and is used for dust prevention. It has a structure in which polyethylene-based synthetic fibers are sandwiched between synthetic resin films, and is highly resistant to tearing. Although there are roll-shaped sheets 12, most general-purpose products are rectangular and each side is reinforced. The sheet guide portion 14 according to the present invention is passed through the seat ring 11 and tied.

The seat ring 11 is a so-called eyelet, which is not shown in the drawings, and holds the seat 12 on the single pipe 10 through the seat guide portion 14 to reinforce the opening hole so that it does not break. .

The sheet guide portion 14 is a tapered portion formed so that one end of the branched guide portion 3 can be easily inserted into the seat ring 11 and the opening hole.
