Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blind mounting bracket for scaffolding temporarily installed in bridge construction on other passages, buildings, private houses, etc.

[0002]

2. Description of the Related Art Conventionally, under a structure 1 such as a bridge, as shown in FIG. 3, a plurality of single steel pipes 2a for longitudinal scaffolding having a length of about 5 m (referred to as "Oyago") are provided. The single steel pipe 2a for scaffolding is hung by the chain 10 and is suspended in a horizontal state, and the single steel pipe 2b for scaffolding in the width direction ([rolling]
)) And connect the intersections with each other via a binding metal fitting (not shown). A safety net (not shown) is stretched in a plane including the steel single pipes 2a, 2b for scaffolding, and the steel pipes 2a, Two
Construction scaffolding 2 with scaffolding board 2d placed on top of it, and to the side of the scaffolding 2, a morning glory scaffolding 3 that is inclined or upright with an upward opening.
Are temporarily installed. The morning glory scaffold 3 is made up of many steel single pipes that are vertically inclined or upright (referred to as "location").
3a and several steel single pipes arranged horizontally (cloth [nuno]
3b) with the cloth 3b inside and combined in a grid pattern, and connected to each other via a binding metal fitting (not shown),
Furthermore, a rafter is tied to the cloth 3b with a number line, and a blindfold plate 7 called a control panel is nailed between the rafters. An enclosing net 8 is stretched on the outer surface of the blindfold.

However, in the temporary construction of the morning glory scaffolding 3, the work of binding the rafters to the cloth 3b with the number lines and nailing the blindfold plate 7 to the rafters requires a considerable amount of work and the nails are dropped during the work. When the scaffolding is removed after the construction is complete, removing the blindfold plate 7 with the nails attached is dangerous because the nails may be pierced or caught on the body / clothes. However, there is a problem that it requires a lot of trouble.

[0004]

The problem to be solved is that the conventional blindfold requires a lot of time and labor for the temporary installation / removal work.

[0005]

A first aspect of the present invention is to provide a sandwiching portion 5 having an H-shaped cross section by a pair of parallel main wing 5a, sub wing 5b, and an intermediate wall 5c connecting the middle of the main wing 5a and the sub wing 5b. A temporary blind mounting bracket 4 which is formed and has a pipe mounting clamp 6 mounted on the outer surface of the main wing 5a, and a plurality of screw holes H for screwing in bolts provided on the auxiliary wing 5b toward the inner surface of the main wing. Is.

A second aspect of the present invention is a temporary blind mounting fixture in which, in addition to the configuration of the first aspect, an eyebolt screwing screw hole J is provided in the center of the auxiliary wing 5b.

[0007]

EXAMPLES Examples will be described with reference to the drawings. 1 is a structure such as a bridge, 2 is a scaffold temporarily installed below the structure 1, and a plurality of single steel pipes for longitudinal scaffolding having a length of about 5 m are used. 2a (referred to as [Oyago]) is suspended by the chain 10 and the steel single pipe for scaffolding 2a is hung in a horizontal state, and the single steel pipe for scaffolding 2b in the width direction (referred to as [rolling]) ) Are mounted on the scaffolding steel pipes 2a and 2b, and the intersections thereof are connected to each other via a binding metal fitting (not shown). A safety net (not shown) is stretched in a plane including the steel single pipes 2a, 2b for scaffolding and the scaffolding steel pipe 2a. , 2b on which a scaffolding board 2d is placed. 3 is a morning glory scaffold inclined to the side of scaffolding 2,
Multiple steel single pipes that incline vertically (location [tateji]
3a) and several steel single pipes (referred to as cloth [Nuno]) 3b arranged in the horizontal direction are combined in a grid pattern with the cloth 3b inside and tightly connected to each other (not shown). ), And a blindfold plate 7 called a control panel is attached to the cloth 3b with the blindfold fitting 4 of the present invention interposed. An enclosing net 8 may be provided on the outer surface of the blindfold as needed.

The details of the blind fitting fitting 4 of the present invention will be described. In the first invention, a cross section is formed by a pair of parallel main wings 5a and sub wings 5b and an intermediate wall 5c connecting the middle of the main wings 5a and sub wings 5b. While forming the H-shaped holding part 5,
A pipe mounting clamp 6 may be attached to the outer surface of the main wing 4a (a bolt (not shown) may be screwed from the holding piece 6a side of the clamp 6 into a screw hole (not shown) provided in the main wing 4a. ), The auxiliary wing 5b is provided with a plurality of screw holes H for screwing bolts toward the inner surface of the main wing 5a. Further, in the second invention, in addition to the configuration of the first invention, an eyebolt screwing hole J is provided in the center of the auxiliary wing 5b. In addition, 9 and 10 are an eyebolt and a chain, respectively.

The pipe clamp 6 has two surrounding pieces 6a, 6b having a circular (FIG. 1) or square (FIG. 2) inner edge.
One end is rotatably coupled with a hinge 6c, a bolt 6d is pivotally attached to one of the other ends by a pin 6e, and a nut 6f is screwed to the bolt 6d. Notch 6 to hang bolt 6d on the end of one enclosure piece 6b
With the h opened, the single tube 11 is surrounded by the surrounding pieces 6a, 6b.
Pinch it with, bolt 6d to notch 6h, and nut 6f
The single tube 11 can be clamped by tightening.

The operation will be described with reference to the drawings. After horizontally sandwiching the cloth 3b by the sandwiching metal fitting 6 which is a part of the blindfold mounting metal fitting 4, the main wing 5a and the auxiliary wing of the sandwiching portion 5 of the blindfold mounting metal fitting 4 arranged above and below. The upper edge and the lower edge of the blindfold plate 7 are inserted between the blindfold plate 7 and 5b, and the bolts screwed from the side of the auxiliary wing 5b are tightened into the plurality of screw holes J for screwing bolts to fasten the blindfold plate 7 to the holding portion 5. In this way, as shown in FIG. 4, a plurality of blind fittings 4 can be horizontally sandwiched between a plurality of steps of cloth 3b, and a plurality of blind plates 7 can be connected to each other in a front-rear, left-right, and planar shape. If necessary, the eyebolt 9 may be screwed into the screw hole J and fixed, and the hook 11 of the hanging chain 10 may be hooked.

[0011]

Since the present invention is constructed as described above,
Unlike the conventional morning glory scaffold 3, it is not necessary to tie a rafter with a numbered line or to nail the blindfold plate 7, and the work is easy, and the scaffolding / blindfold temporary installation / removal can be performed quickly and safely. You can do it.
