Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to temporary backfilling of pipe penetrating sleeves,
Specifically, in buildings made of concrete, after pipes such as water supply and drainage pipes are installed through a sleeve installed in a floor slab, the problem occurs between the inside of the sleeve and the outside of the pipe. When backfilling a void with mortar or the like, the present invention relates to something that serves as a shield on the lower surface of a slab to prevent the mortar from flowing down.

(Prior Art) Conventionally, this type of cover plate has been fixed using a plywood board, for example, by the following means. That is, the fifth
As shown in the figure, a circular hole with a diameter slightly larger than the outside diameter of the pipe 1 to be piped is provided in the center of a suitably large plywood board, and the hole is divided into approximately two equal parts. Cover plate piece 2, 2
Attach the tube 1 to the underside of the slab 3 so as to sandwich it from both sides, and fix it by nailing it to the underside of the slab 3 so as to close the opening at the bottom end of the sleeve 4, or attach it to the cover plate pieces 2, 2. The ↑1 gold 6 etc. passed through the small hole provided was passed through the sleeve 4 and pulled up to the top surface of the slab 3, and the upper end of this ♀-1 gold 6 was picked up at the construction site. The upper end of the pipe can be fixed by tightening it with appropriately shaped pieces of wood 7, reinforcing bars 8, etc., or, although not shown, fix several pieces of wood to the pipe under the slab with 4-metal gold. Using the section, a suitable piece of wood was then used as a support rod and fixed with a hammer lυ.

However, the conventional method of fixing the backing board using plywood A7 board or its fixing work was difficult to create a perfect circular hole with an appropriate diameter on the plywood A7 board at the construction site, so it was used for backfilling. The so-called slag of mortar material tends to drip, and is that? Not only was it irrational that it took an extremely long time considering the nature of the work and required multiple workers, but also that the fixing of the backing plate was insufficient from a technical point of view, and in the end the construction itself was inadequate. There was a drawback.

(Problems to be Solved by the Invention) It is an object of the present invention to be able to easily attach and fix the pipe that runs through the sleeve of the floor slab, and to prevent the flow of mortar from using the conventional patch plate. The object of the present invention is to provide a temporary backfill for a tube sleeve that can be effectively prevented from burning.

(Means for Solving the Problems) The temporary backfilling of the pipe penetrating sleeve according to the present invention is such that the outside diameter J of the vertical pipe is slightly larger than 10; nine neck holes are formed, and An insertion opening with a width approximately the same as the diameter of the fitting hole is formed to communicate the fitting hole with the outer circumference, and a groove for guiding is formed along the end surface of the insertion hole, and a vertical pipe is provided at the bottom. The 1Φ inlet can be covered by the insertion opening of the main body, which is formed with a tightening part having a screw that is screwed into the wall of the main body to tighten the vertical pipe.

The present invention is characterized in that the shielding MFA having a shape of 1 is assembled flush with the main body by being guided to the concave strip of the insertion opening via the protruding strips formed on the left and right end faces of the shielding MFA.

(Embodiment) Next, the structure of an embodiment of the present invention will be explained based on the drawings. The temporary support 9 for backfilling a pipe penetrating sleeve is composed of a main body 10 and a shielding plate 11 assembled to the main body 10. .

Although the main body 10 is shown as having a circular outer shape in the figure, it is not limited to this shape, and may have a rectangular outer shape or other shapes as other embodiments. Then, approximately in the center of the main body 10, a circular lf\i hole 1 fitting 13 with a diameter slightly larger than that of the vertical pipe 12 to be described later is formed, and the lf\i hole 13 is connected to the outer periphery of the wood (A10). The insertion opening 14 is cut out to have a width that is approximately the same as the diameter of the fitting hole 13. Reference numeral 15 denotes a guiding groove formed along the edge of the insertion opening 14. Although the figure shows a triangular cross-sectional shape, the present invention is not limited to this, and as another example, the cross-sectional semicircular shape may be formed in the shape of the front surface following the shape.

Next, the tightening part 16 has a notched cylindrical shape along the inner peripheral edge of the lower end of the fitting hole 13! r! 65 pieces are provided, and both ends thereof are not extended to the hanging surface J along the insertion opening 14. A pair of pedestals ff117.17 each having a female screw threaded therethrough are formed in the opposite direction of the appropriate part of the tightening part 16, and a screw 18.18 is screwed into each of them from the outside.

Next, the shielding plate 11 has a shape capable of shielding the insertion port 14, and the inner end that should come into contact with the vertical pipe 12 during use is formed into an arc shape with the same diameter as the first medical insertion hole 13. . On the left and right side end surfaces of the shielding plate 11, protrusions 19 are formed which fit into the grooves 15 on both end surfaces of the insertion port 14.

In addition, in other embodiments, protruding stripes having an appropriate cross-sectional shape are formed on both end surfaces of the insertion opening 14 of the main body 10 in place of the nU recessed strips 15, and on the left and right side end surfaces of the shielding plate 11. It is also possible to form a concave strip that fits in one line with this.

When the grooved line 15 and the grooved line 19 or the grooved line and the grooved line of the other embodiments provided in place of these are fitted together, the upper surfaces of the main body 10, mr & plate 11 become as follows. There is.

In addition, 20 is a grip part that is vertically disposed at the outer end J of the lower surface of the shielding plate 11.

(Function) Next, the function of this embodiment will be explained. As shown in FIGS. 3 and 4, after installing a vertical pipe 12 such as a water supply pipe or the like through the sleeve 22 provided in the floor slab 21, the main body 10 is inserted into the vertical pipe 12 from the direction of the insertion port 14. 1st
As shown in the figure, the vertical pipe 12 is accommodated in the 11χ shield hole 13,
EQ in which the top surface of the main body 10 is in close contact with the bottom surface of the floor slab 21
4, and then tighten the standpipe 12 from the opposite direction with the pair of screws 18 and 18 of the tightening part 16 (=l 4J) to fix the main body 10 in position with respect to the standpipe 12.

Then, hold the shielding plate 11 by its gripping part 20 and insert it into the insertion opening 1.
It is necessary to enter the shielding plate 1 from the opening direction of No. 4 through the convex line 19 toward the east into the concave line 15 of the insertion port 14 until the arc-shaped inner end of the shielding plate 1 comes into contact with the vertical pipe 12. Ru.

As a result, the main body 10 and the shielding plate 11 are used with their upper surfaces flush with each other, and the lower end opening of the sleeve 22 is located between the vertical tube 12 and the fitting hole 13 of the main body 10 and the arc-shaped shielding plate 11. Since the sleeve 22 is almost completely sealed except for a small gap between the sleeve 22 and the inner end, when the mortar material 23 is poured from the upper end opening of the sleeve 22, it hardly flows downward, and the mortar material 23 After solidification, the temporary support 9 can be easily removed by reversing the procedure described above, and the sleeve 22 is backfilled flush with the floor slab 21 (effects of the invention). Because it has the above structure and function, one person can easily and quickly install and remove the temporary holder, and the temporary holder can be firmly fixed in position on the vertical pipe.
It also has the effect of completely preventing the mortar from flowing down and allowing it to be finished flush with the floor slab.
