Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to work shoes for asphalt construction, which are worn during asphalt laying work such as road paving.

(Conventional technology) Asphalt work such as road paving is carried out by laminating a heated mixture of aggregate and asphalt on the road surface and leveling it with a finishing machine. Immediately after, the asphalt surface was at a high temperature of approximately 120℃.

When working on such high-temperature asphalt, the soles of your feet will be too hot to work with regular work shoes, so you should wear work shoes with rubber soles about 5 cm thick, or wear shoes with rubber soles that are about 5 cm thick. A thick rug is placed between the walls to reduce the effects of heat and improve work efficiency.

(Problem that the invention aims to solve) However, even if you wear work shoes with rubber soles that are about 5 cm thick, or even if you insert a rug, you will not only not be able to obtain a sufficient insulation effect. , the weight of the shoes is heavy, and they are also uncomfortable, making it difficult to work.
There are problems such as severe fatigue, and there is a pressing need for a solution to this problem.

The present invention has been developed in view of the current situation, and it is an object of the present invention to provide work shoes for asphalt construction that are lightweight and have a high heat insulating effect.

(Means for Solving the Problems) In order to achieve the above object, the asphalt construction work shoes of the present invention have the sole of the shoe body combined with a rubber sponge layer bonded to the midsole and a rubber sole serving as the ground contact surface. It has an integrated construction with a pressed cork layer impregnated with resin as a binder and having excellent heat insulation properties interposed between the two.

(Example) Next, an example of the work shoes for asphalt construction of the present invention will be described based on the drawings.

Figure 1 is a side view of a partially broken state when the present invention is applied to short boots for asphalt construction work, and Figure 2 is a partially broken side view when the present invention is applied to boots for asphalt construction work. This is a side view of the sole 2 of the shoe body 1, with a rubber sponge layer 4 of about 10 mm thick adhered to the midsole 3 and used to provide cushioning properties, and a rubber sponge layer 4 used as the ground contact surface to prevent wear. A compressed cork layer 6 impregnated with resin as a binder and having heat insulation properties is interposed and integrated between the rubber sole 5 and the rubber sole 5, which is about 10 mm thick. The structure is such that a decorative tape 7 is wrapped around it to prevent this and hide the exposed state of the layers.

(Operations and Effects of the Invention) The asphalt work shoes of the present invention have a pressed cork layer with excellent heat insulation properties impregnated with resin as a binder between the rubber sponge layer and the rubber sole. Since the rubber sole is used as the ground contact surface, the heat transmitted from the rubber sole to the inside of the shoe is blocked by the pressed cork layer, which has excellent insulation properties, without losing the cushioning properties of the entire sole. At the same time, by inserting a lightweight pressed cork layer,
The overall thickness of the sole can be made thin and lightweight, and since the pressed cork layer is protected by the rubber sole, the sole has excellent durability.

Therefore, according to the present invention, the disadvantages of conventional work shoes for asphalt construction, which try to improve the heat insulation effect by thickening the sole or inserting a rug, can improve the workability due to the increased weight and tightness of the shoes. It is possible to provide optimal asphalt construction work shoes that are lightweight and have a high heat insulation effect, eliminating the reduction in fatigue and the severity of fatigue.
