Abstract

PURPOSE:To contrive the promotion of efficiency for execution by installing a flange in a base, while forming a semicircular receiving part for a sleeve so as to hold a cylindrical mating part rising from this flange, and making an opening of a presser tool so as to be fitted in a circular cylinder installed in the receiving part. CONSTITUTION:The above-captioned sleeve fixture is set down to a receiving tool (a) provided with a flange A and made up of forming a semicircular receiving part C so as to hold a cylindrical mating part B rising from this flange A, and it consists of a presser tool (b) formed in U-shaped form. In addition, a circular cylinder 6 is formed in the tool (a) and an opening 8 in the tool (b), respectively. The tool (a) is nailed to each falsework at both sides, a paper sleeve is placed on the receiving part C, the opening 8 of the tool (b) is applied to the circular cylinder 6 from the upper part, thrust in and fitted therein, and thus any falling of the tool (b) is prevented from occurring. Consequently, the shortening of a term of work and the promotion of operation efficiency are thus promotable.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention securely fixes a paper sleeve at a predetermined position to a penetrating part of a column, beam, floor, wall, culvert, etc. during concrete construction, and allows concrete, etc. to flow into the sleeve. The purpose is to prevent this and ensure prompt construction.

The conventional construction method is to cut the paper sleeve appropriately, nail it directly to the temporary frame, fill the gap between the temporary frame and the sleeve with tape, pour concrete, and apply vibration using a vibrator etc. This is a common construction method. With this method, the sleeve position may be unclear due to pressure during concrete pouring, vibrations from vibrators, etc., expansion of the temporary frame, moisture in the concrete, falling off the temporary frame, misalignment, concrete inflow, etc. This may lead to re-measurement, correction, chipping for correction, drilling, and in the worst case, changing or increasing piping materials, changing the design, etc. This increase in labor, machinery, and materials can, in rare cases, affect the construction period.

To describe the present invention with reference to drawings, the position of the receiving tool A is determined by measuring and marking the temporary frame on both sides in advance.
Align the stamp 2 and the notch 3 with the black ink, and nail it using the nail hole 1. When assembling the reinforcing bars, insert the appropriately cut paper sleeves into the reinforcing bars, drop them into the temporary frame, place the sleeves on the receiving part C, and push the opening E8 of the holding tool A firmly into the cylinder 6 of the fixed part from above. Then, the opening 9 of the opening E is pushed wide and fitted into the opening 10 of the opening E. 50 umbrellas are
The oblique portions 4 and 7 on both wings of the receiving part C and the holding tool A are for preventing the holding tool A from falling off and allowing the holding tool A to quickly engage the both tools. By fixing only one side of the sleeve using the nail holes of the holding tool A and leaving the other side open, it is possible to accommodate expansion of the temporary frame.

By using the present invention, accidents can be overcome and construction can be carried out smoothly. Therefore, the economic effects of shortening the process and streamlining the work are significant.

Claims (1)

[Claims] A material having appropriate softness and strength is used, and the thickness, width, and length are appropriately selected so as to have a flange A at the base and a cylindrical mating part B rising from the flange A. Wrap the material in a semicircle to form a receiving part C. The tsuba A is divided into eight equal parts, each having a nail hole 1 for fixing, a mark 2 for positioning, and a notch 3 at the end. Both wing ends of the receiving part C are shaved obliquely 4 from the outside to the inside, and a cylinder 6 having an umbrella 5 on the top at an appropriate position serves both as a guide and a hook, and is used as a fixed part D to form a receiving tool A. To hold it down from the top, cut a U-shaped strip to match the inner diameter of the receiving part C, drill a nail hole 1 in the bottom, make a diagonal 7 in both wing tips from the inside to the outside, and attach the fixing part. An opening E is made to match D, the entrance is widened into a hakama shape 8, and the part where the cylinder 6 of the fixing part D contacts is made extremely narrow 9, and then gradually enlarged 10 so that the cylinder 6 is fixed. A sleeve installation tool consisting of two tools, A and A.
