Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a mortar filling tool for piping penetration sleeves, and more specifically, a mortar filling tool for penetrating pipes into floors, walls, etc. The present invention relates to a filling tool for filling mortar between a sleeve and the pipe.

[Conventional technology]

Conventionally, in order to install piping across a floor or wall, etc., a sleeve was installed through the floor or wall, the piping was passed through the sleeve, and the airtightness of the floor or wall was ensured. In order to do this, work is being done to fill mortar between the sleeve and the piping.

In the past, for example, in order to fill mortar, concrete panels or wood were cut together with a saw at the site and held together with wires, bolts, etc., but this conventional filling tool was only suitable for filling mortar once. I can not use it. In addition, in the case of relatively small sleeves, filling with mortar was done manually without using a plate, etc., but this had the disadvantage that it took a lot of man-hours and the filling finished poorly. .

[Problem that the invention attempts to solve]

The present invention aims to eliminate the above-mentioned conventional drawbacks, simplify and improve the efficiency of mortar filling work, reduce the number of man-hours on site, and provide a mortar filling tool with a good finish.

[Means for solving problems]

In the mortar filling tool for a pipe penetration sleeve according to the present invention, the pipe penetration hole is provided eccentrically from the center, and the weir plate is cut in half through the hole, and each half of the weir plate is attached to the mounting surface. a weir plate connecting member that connects and fixes the halved weir plates to each other by pressing against the piping and sandwiching the piping; a mortar injection hole drilled in the weir plate; and an air vent hole drilled in the weir plate; It has an air vent tube that is piped to the air vent hole and has an upwardly bent tip.

[Effect]

Pass the pipe through the pipe penetration sleeve, press the weir plate against the open end of the pipe penetration sleeve, fix the weir plate connection member to the pipe to hold down the weir plate, and inject mortar from the mortar injection hole. Ba,
Mortar can be filled easily and with a good finish.

When pouring mortar, the air between the sleeve and the pipe is pushed out through the air vent pipe when the top surface of the mortar is above the height of the air vent hole, and when the top surface of the mortar exceeds the height of the air vent hole, it is pushed out to the outside through the weir plate. It is pushed out through a small gap (a gap that does not allow mortar to leak) between the top and the mounting surface such as a wall.
