Abstract

PROBLEM TO BE SOLVED: To provide s construction spacer capable of being simply mounted to a floor bar built up in a floor, a wall a column and a beam form, a wall bar, a column bar and a beam bar and, at the same time, surely holding a coating of reinforcement. SOLUTION: A concrete heavy spacer is so constituted that a standard cone or pyramid mortar or concrete 3 surely holding the coating of the reinforcement is integrally provided to a proper place of an anchoring tool 2 formed of a washer 2b and a wing nut 2c to a bolt 2a in order to put on the reinforcement. After it is fixed with the bolt 2a, slippage and rotation can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction spacer for accurately retaining a reinforcing bar when a concrete structure is mainly constructed with floors, columns, beams and walls.

[0002]

2. Description of the Related Art In conventional construction spacers of this type, a cubic mortar or concrete spacer is fastened with a wire, or a doughnut-shaped spacer made of synthetic resin is used in place of the spacer. It is unstable and it is difficult to keep the rebar coating accurate. Also, cube mortar or concrete may fall off when used on the floor for long-term maintenance. The doughnut-shaped spacer made of a synthetic resin is unstable at the time of placing concrete, and foreign matter is mixed therein, leading to a decrease in the strength of the structure.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-mentioned problems, and has as its object to provide a rigid and easy attachment to floors and walls, and reinforcing bars arranged in columns and beam forms. Another object of the present invention is to provide a construction spacer capable of accurately retaining a reinforcing bar coating.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention integrates a conical or pyramid mortar or concrete mortar in a proper position of a fixture formed by a washer and a wing nut on a vault to be attached to a reinforcing bar. It is a configuration provided in

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The construction spacer of the present invention comprises:
First, it is fastened and fixed to the vault with a fixture formed of a washer and a wing nut. The covering can be made of conical or pyramid mortar or concrete and can be held accurately.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to FIG. 1 is a construction spacer. Numeral 2 denotes a fixture, which is formed by assembling a washer 2b and a wing nut 2c on a vault 2a so as to be fixed to a reinforcing bar. Reference numeral 3 denotes a construction spacer provided on the reinforcing bar fixing portion in the form of a cone or a pyramid made of mortar or concrete having a length similar to that of the coating in the linear direction.

As an example of use of this embodiment, as shown in FIG. 2, a fixing tool 2 formed of a washer and a wing nut is appropriately mounted on a reinforcing bar A or B prearranged as shown in FIG. And fix it with 2c. In this state, it is possible to accurately secure the coating of the reinforcing steel with 3 having the same length as the coating in the linear direction.

The above construction spacer is changed depending on the width of the coating.

[0009]

According to the present invention, there is provided a construction spacer characterized in that it can be easily mounted on a reinforcing bar by the above-mentioned structure, and the bottom or side surface can be covered accurately.
