JPS59136337A - Material softenable by electric current - Google Patents

Abstract

PURPOSE:To provide a material softenable by electric current, and useful for the simple and sure working in the construction field, etc. according to the purpose of application, e.g. adhesion, filling, etc., by distributing conductive fibers in a material plasticizable or meltable with heat. CONSTITUTION:Proper amount of conductive fibers (e.g. carbon fiber, steel wool, etc.) are distributed in a material having thermoplastic or thermomelting property (e.g. asphalt). The obtained material is softened by passing electrical current, and formed in various forms.

Description

[Detailed Description of the Invention] The present invention enables easy and reliable construction work when bonding materials together, filling gaps, and applying waterproof layers and outer surface layers of structures. It is related to the materials used in the process.

Conventionally, when asphalt or other thermoplastic materials are used in construction work, the method is to heat them up with a heating device, then transport them to the construction site, and complete the work before the temperature cools down. Transporting heavy objects at high temperatures is dangerous, time is rushed, quality control is difficult, and maintaining heating equipment is troublesome, so special solvents are used to soften the materials and construction is carried out at room temperature. However, the strength decreased,
Depending on the type of volatile gas in the solvent, it is dangerous to work in a closed room, and curing takes a long time.

Therefore, the present invention aims to incorporate thermoplastic or thermofusible materials into
The above drawbacks are solved by distributing conductive fibers such as carbon fibers or steel wool as required for heating, and heating the fibers with electricity.

Further features and advantages of the invention will be explained below with reference to the drawings.

Figure 1 shows an example of using the present invention to affix tiles to the surface of concrete pavement to improve its durability and aesthetic appearance. Fiber (,2) 2% by volume
When the present invention, which has been mixed and formed into a cloth shape, is placed on a paved road, tiles (j) are placed on top of it, and iron wires (a) are placed on both ends of the heated part and electricity is applied, the temperature of the main body rises and becomes soft. It adapts to the undulations of the contact surfaces of the upper and lower materials and adheres closely, and some of the asphalt melts and oozes out, adhering well to the materials on the upper and lower surfaces.When the current is turned off, the body cools and hardens. Tiles are firmly bonded to concrete. Even if the main body hardens over time, if you push the iron wire into both ends of any section and apply electricity, that part will be reheated and the tile can be removed for repair. It is easy. Since division construction and modification are easy, the present invention can be easily applied to walls with complicated shapes.

As described above, the present invention has effects such as making the work of adhesion and filling safe, simple, and inexpensive, making the work of adhesion and filling reliable, and facilitating repair and replacement.

Note that if fibers or nets are inserted into the main body in addition to the conductive fibers, the main body will be further reinforced and will be easier to handle.
