Abstract

PURPOSE:To make it sure and accurate to fix a sleeve to passing through-parts of a column, beam, floor, wall, culvert and the like and to enable execution by having an equipment for making the installation to a base easy by using a material provided with soft or hard characteristics properly, and providing a cylindrical and expansible equipment on the base to form. CONSTITUTION:A sleeve is alloted to a position to be inked over a temporary form by means of a: cut, b: nail holes, c: lines and others of a standard scale provided to a base 1 accurately with nails or tackers and others. After that, the sleeve is cut off in shorter than the width of a beam. Then, in case the frame width of reinforcing bars is wider than a diameter of the sleeve, and in cast is it shorter than the diameter of the sleeve, it is housed into a hoop temporarily after the completion of arrangement. When the arrangement of reinforcing bars completes, one side of the sleeve is inserted into an inlet 2 of the base 1, the other hand thereof is alloted to an inlet 2 of the opposite base 1, the inlet 2 is pulled up to expand a expansion section 3, and the sleeve is wrapped. The sleeve is placed to a specific position accurately by applying the same process to a previously inserted part.

Description

[Detailed description of the invention] The present invention is used when constructing RC construction.
The purpose is to accurately and reliably fix sleeves to penetration areas such as floors, walls, culverts, etc., making construction easier.

In the conventional RC construction method, a sleeve made of A1 paper or the like is cut as accurately as possible according to the thickness and width of the beam or wall, etc., and if it is smaller than the reinforcing steel, it is inserted between the reinforcing bars in the reinforcement assembly and temporarily cut. Nail directly into the frame f-th. If there is a gap between the temporary frame and the sleeve, wrap it with tape, etc. and fill it.

B: If the diameter of the reinforcement is larger than the diameter of the sleeve, temporarily fasten it to the assembled reinforcing bars, and after arranging the reinforcement, carry out construction in the same manner as in A. C
, AB in combination, nails are accurately driven into the inner diameter of the sleeve from outside the temporary frame to prevent it from falling off.

In this kind of construction, the work is extremely difficult, the fixing is uncertain, and the expansion of the temporary frame due to the inflow pressure (lateral, pressing, etc.) during concrete pouring and vibration caused by the vibration router. , due to which the sleeve starts to move from the position,
It may move away from the temporary frame, be displaced, or in the worst case, be completely buried, resulting in huge costs for subsequent treatment.

In other words, when the temporary frame is removed, the zero penetration part cannot be determined. ■
Cotocrete is stuck inside the sleeve. ■The sleeve is completely unknown. etc. are occurring. The way to deal with this is to re-measure and find the penetration part (sleeve), and if it is too out of place, remove the sleeve, fill the hole, and drill at the specified position, or drill the hole by hand. .

In the case of a drill, the reinforcing steel may be cut, which may damage the structure, and if the hole is drilled by hand, it will take a very long time and cost a lot of money.

To explain the embodiment of the present invention using two Cs, it is possible to accurately move to the marked positions on the temporary caulking frame by using the guide gauge A, cut/opening, nail hole/C, line, etc. provided on the base 1. Addressed to,
Tighten with a nail or tacker, then cut the sleeve to a length shorter than the beam width. If the width of the reinforcing bar is wider than the sleeve diameter, place it in B after placing it. If it is narrower than the sleeve diameter, temporarily put it in the hoop bar. After completing the placement of reinforcing bars, base 1
One side of the sleeve is inserted into the introduction port 2 of the base 1 on the opposite side, and when the introduction port 2 is pulled, the elastic part 3 will extend and wrap around the sleeve. By doing the same with the part that was inserted first, the sleeve will be accurately placed in the specified position. large
