Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a weight for stabilizing a simple fence (hereinafter simply referred to as a moving fence) used at a site such as road construction and construction work.

[0002]

[Prior Art]

 In road construction or construction work, a moving fence is placed at the boundary to avoid the entry of ordinary people into the site.Since this moving fence is made relatively lightweight, it is blown during strong winds such as typhoons. There is a risk of being skipped, and even a slight shake or contact easily causes it to fall. Therefore, if the skipped fence hits a passerby or a person involved in the construction, there is a risk of injury, and a fallen fence is dangerous. Therefore, in the past, hanging a bag filled with sand on the top rail of the moving fence to prevent it from flying due to its weight, or passing a concrete block to the bottom rail, placing a tank containing water. I am trying to stabilize it.

However, according to the above-mentioned conventional means, first, the sand bag is cheap and economical, but since the irregular bag body is hung, the appearance is bad and gives the impression of a very dirty construction site. In addition, there is a drawback that the weight is not satisfied even by the concrete and the tank body, there is a risk of being blown off by a strong wind, and the appearance is ugly.

[0004]

[Problems to be solved by the device]

 Therefore, the present invention secures the safety of the construction site by keeping the moving fence stable even when strong wind blows, and improves the appearance of the construction fence to wipe away the image of a dirty construction site. It was an attempt to develop such a device.

[0005]

[Means for Solving the Problems]

 In the proposed weight, a bifurcated body that straddles the lower rail of the moving fence is formed with a relatively heavy weight, and a weight body is formed by arranging connecting pieces with small holes on both sides of the body. It is composed of a U-shaped rod that can be inserted into the main body.A split groove is formed at the tip of the rod to provide a spindle on a part of the rod, and a wedge body that is attached to the spindle and has a slide groove is provided. It is characterized in that it is provided with a connecting tool provided, and the weights are connected to each other in a chain shape by the connecting tool.

[0006]

[Action]

 By covering the lower rail of the moving fence by straddling the fuselage, the fence formed of a relatively heavy object is restrained from rising and stabilizing the moving fence. At the same time, insert a U-shaped rod into the abutting part of the connecting pieces arranged on both sides of the body, and form a wedge body attached to the tip of the rod between the spindle and the wall of the small hole. When it is pushed into the closed space, the connector and the connecting piece are fixed by the wedge action, and they are connected to each other in a chain shape, and they are connected to each other against the force such as wind or shaking, and show a stronger stability. ..

[0007]

【Example】

 An embodiment of the present invention will be described below. In FIG. 1, reference numeral 1 is a moving fence placed at a construction site or the like, and an upper rail is passed to a triangular side arm rod 2 and a lower rail 3 is passed to a lower side. A horizontal rod is being passed to the lower rail 3.

In FIG. 2, reference numeral 4 denotes a weight body. First, a forked body 5 straddling the lower bar 3 is formed, and a connecting piece 7 having small holes 8 is formed at both left and right ends thereof. To do. The body 5 is formed, for example, in an inverted U shape in cross section, and has a structure in which the crotch portion 6 straddles the lower crosspiece 3 and supports it when the fence is lifted. The connecting piece 7 is for connecting the weights to each other in a chain shape. The outer side surface of the forked body 5 is extended and passes through the side of the armpit 2 to face the adjacent connecting piece 7. To do it. It is preferable that the body 5 and the connecting piece 7 are formed of a comparatively heavy material. For example, the thermoplastic resin is mixed with a filler having a large specific gravity, and the synthetic resin utilizes waste. Is desirable.

Next, reference numeral 10 is a connecting tool for connecting the connecting pieces 7 to each other. First, split grooves 12a and 12b are formed at the ends of the U-shaped rods 11a and 11b, and part of them is cut. The support shafts 13a and 13b are fixed. On the other hand, wedge bodies 14a and 14b forming an inverted triangle with slide grooves 15a and 15b arranged in the center are arranged with a spindle attached to the slide grooves. One side of the triangle along the slide groove 15 of the wedge body 14 is larger than the diameter of the small hole 8 of the connecting piece 7, and the remaining one side is short enough to allow the small hole 8 to pass.

Next, the operation of the weight of the present invention will be described. For the moving fence placed at a construction site or the like, the crotch portion 6 is passed through the opening of the body 5 of the weight 4 of the present invention opened in an inverted U shape. Cover 3 and cover. It is desirable to hang both the lower rails 3 on the front and rear, but it is also possible to use either one.

Next, the U-shaped rods 11 a and 11 b of the connecting tool 10 are inserted into the connecting piece 7 extending from the body 5 to the left and right toward the small hole 8. Then, the wedge bodies 14a, 14b at the tip that have passed through the small hole 8 are pinched, and the wedge bodies 14a, 14b are pushed down along the slide grooves 15a, 15b engaged with the support shafts 13a, 13b. Then, the wedge bodies 14a and 14b forming an inverted triangle are pushed into the space formed between the support shafts 13a and 13b and the wall surface of the small hole 8, and the connecting tool 10 and the connecting piece 7 are separated by the wedge action. Securely fixed.

Therefore, when a strong wind blows and the moving fence is about to be blown away, the lower bar 3 hits the body 5 of the bifurcated weight 4 against the floating moving fence and is suppressed by this and is stable. Turn into. Further, as described above, when the connecting pieces arranged on both sides of the body are connected by the connecting tool composed of the U-shaped rod having the wedge body attached to the tip thereof, strong wind or the like is caused on a part of the moving fence. Even if it is used, it is propagated to the weights linked to each other in a chain, and they cooperate to act as a drag, exhibiting a stronger stability.

Further, the weight 4 can be molded and colored easily if it is made of a synthetic resin such as a thermoplastic resin, so that the weight 4 can be designed in an excellent shape, and the coloring gives a rich color. And improve the image of a dirty construction site. Further, the synthetic resin is not limited to virgin resin, and waste synthetic resin can be reused, which is preferable from the viewpoints of economy and resource utilization.

[0014]

[Effect of the device]

 According to the weight of the present invention based on the above configuration, the lower crosspiece is straddled by the crotch portion of the body, and the U-shaped rod is inserted into the small hole of the connecting piece extending from the body and is attached to the spindle. If the wedge is pushed down along the slide groove, the wedge is pushed into the space formed between the support shaft and the wall surface of the small hole, and the connector and the connecting piece are fixed by the wedge action. The installation work is very easy. Even if a strong wind blows and the moving fence rises, the body that straddles the lower rail suppresses this, and the weights are connected to each other in a chain shape, so that they cooperate with each other for further stability. The danger that the moving fence will blow away will be eliminated. Furthermore, since a synthetic resin with a high moldability can be used, it has a good design and appearance, and if a discarded synthetic resin is used, it is a very useful idea to reuse resources.
