Abstract

PURPOSE:To enable a linear element to be easily anchored in a desired position without the use of any tools by mounting a plurality of slidable clamps on the axial outer peripheral surface of the linear element, and fitting the clamps around reinforcing bars or steel frames. CONSTITUTION:A plurality of clamps 1 molded from a synthetic resin are removably and slidably provided on the axial outer peripheral surface of a linear element 2. Each of the clamps 1 has a clamp main body 1c formed of said synthetic resin and consisting of a first groove 1a of U-shaped cross section and a second U-shaped groove 1b perpendicular to the groove 1a, with the groove 1a fitted around the linear element 2 so that each clamp 1 is slidably mounted on the element. The grooves 1b are pressed to fit over subjects to be installed, e.g. reinforcing bars 3. A linear heating element A can therefore be mounted easily while crossing the regularly spaced reinforcing bars 3 at right angles with the grooves 1b fitted around the reinforcing bars 3, and mortar or concrete is poured thereafter to embed the linear heating element A in a floor face (p) and a wall face, or a roof, a road and the like.

Detailed Description of the Invention

[0001]

[Industrial application] In recent years, snow melting devices buried in roads and roofs in snowfall areas, heating and heat insulating devices buried in floors and wall surfaces of buildings, and wires coated with insulating carbon fiber shorts Heating elements have come to be used as effective heat transfer media. This heating element has excellent flexibility, strength and thermal efficiency,
Moreover, it is very effective in that a desired electric resistance value can be easily set.

[0002]

This linear heating element is often used by embedding it in a road, roof, floor, wall surface, etc., but it has been conventionally used to fix it in place. In this method, a fixture is attached to a fixed surface such as a reinforcing bar or a core material, and a means for holding the linear heating element by this fixture is adopted. However, with this conventional means, the work of attaching a large number of fixtures to the fixed surface with screws or the like before embedding the linear heating element is very complicated and presents a major obstacle. In particular, when the linear heating element is attached in the direction orthogonal to the reinforcing bar, the operation becomes more troublesome.

Therefore, the present invention provides a linear heating element which can be attached in a direction orthogonal to a reinforcing bar or a steel frame as a core material of a floor or wall of a building or a structure without requiring any tools. Then, the main purpose is to solve the above problems.

A second object of the present invention is to provide a mounting tool which can connect the linear heating elements to each other or the linear heating elements and the reinforcing bars to be mounted in a cross shape by a simple operation. It is to provide at a low price with a simple structure made of an integrally molded product.

A large number of fixtures (1) ... are slidably attached to the outer peripheral surface of the linear body (2) at appropriate intervals in the axial direction. In this structure, a fitting groove (1b) having a U-shaped cross section, which is oriented in a direction orthogonal to the axis of, is formed.

Further, according to the present invention, a first fitting groove (1a) having a substantially U-shaped cross section extending linearly, and the first fitting groove (1)
The second fitting groove (1b) having a substantially U-shaped cross section extending in the direction orthogonal to the axis of a) is formed in the fitting body (1c) made of synthetic resin, and the first fitting The groove (1a) is formed to have a size to fit and hold the linear body (2) in which the carbonaceous short fiber is used as the core wire (2a) and the core wire (2a) is covered with the insulating coating material (2b). The two fitting grooves provide a fitting for a linear heating element that is sized to fit the linear body (2) or the linear article.

[0007]

The above linear heating element (A) is fitted with the second fitting groove (1b) on the rebars (3) arranged at regular intervals as shown in FIG. 1, for example. By doing so, it is possible to easily attach the reinforcing bars (3) in a state of being crossed at right angles. After that, by pouring mortar or concrete, it is buried in the floor surface, wall surface, roof, road or the like.

Further, the above-mentioned fitting (1) has a first fitting groove.
