[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a filler material flow-preventing device for a block hole, which prevents the flow of a filler material such as mortar poured into a vertical hole of a block.

[0002]

[Prior art]

 Conventionally, many of the walls were constructed of masonry by using concrete blocks because they are lightweight and inexpensive. At the top of the constructed block wall, the vertical holes in the concrete block were exposed, which looked bad and rainwater was flowing in. Therefore, for example, a concrete roofing material was provided on the upper surface of the upper concrete block, and a lump of filling material such as mortar having a viscosity was filled in the upper part of the vertical hole for finishing. Further, when a horizontal reinforcing bar is provided on the upper part of the block in the middle of the block wall, the reinforcing bar is arranged between the upper and lower blocks and a filling material such as mortar is filled.

[0003]

[Problems to be solved by the device]

 However, in the method of filling the block wall with the filler such as mortar, since the filler itself has a weight and the vertical hole does not have the support of the filler, the filler flows down and a large amount of the filler is required. . Further, there is a problem that the filler cannot be pressed and clogged to prevent it from flowing down, and the adhesive force with the vertical hole is weak, and the filler drops even after the filling. The present invention has been made in view of such circumstances, and does not flow down even if a filler such as concrete is packed in the upper part of the vertical hole of the concrete block, and it is pressed to increase the adhesive effect with the vertical hole. It is an object of the present invention to provide a filler flow-down prevention tool for a block hole that can be used.

[0004]

[Means for Solving the Problems]

 The filler flow-down prevention tool for a block hole according to claim 1, wherein the flow-through prevention member is provided in the middle of the vertical hole of the block to prevent the flow-down of the filler such as mortar, and a plurality of flow-down prevention members. And a hanging member provided with a hooking portion that is hooked on the edge of the vertical hole.

[0005]

[Action]

 In the block hole filler downflow prevention device according to claim 1, the downflow prevention member is sunk to a predetermined depth in the vertical hole of the block, and the hooking portion of the hanging member is hooked at the edge of the vertical hole to form the hook. Fix the filler flow prevention device in the vertical hole. Then, a filling material such as mortar is packed in the vertical holes to close only the upper portion of the vertical holes. In the filling process of the filling material, a downflow prevention member is fixed to the vertical hole, so that the filling material does not flow down below the vertical hole unnecessarily and sink, thereby preventing waste of the filling material. You can Further, since the filling material can be pressed and packed, the effect of adhering the filling material and the vertical holes can be enhanced.

【Example】

 Next, an embodiment of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention. FIG. 1 is a perspective view showing a process of using the blocking material filler downflow preventer according to the first embodiment of the present invention. A block hole filler downflow preventing device 10 according to a first embodiment of the present invention is made of a viscous synthetic resin material such as polypropylene or vinyl chloride, and has an elliptical plate shape as shown in FIG. And a long plate-shaped suspension member 12. The downflow prevention member 11 and the suspension member 12 are integrally formed via a folding groove 13, and a hanging portion 14 is provided at the tip of the suspension member 12. The molding method is an injection molding method, and the filler flow-down preventive tool 10 is provided at low cost. In this embodiment, the size of the downflow prevention member 11 is formed to be about 90% of the size of the vertical hole 16. However, since the mortar is sticky, the space between the downflow prevention member 11 and the vertical hole 16 is small. There is no problem even if there is a gap, and the size of the vertical hole 16 may be about 95% to 75% and used. Reference numeral 17 is a reinforcing bar groove for reinforcing horizontal bars.

Next, a method of using the filler downflow prevention tool 10 when constructing the block wall will be described. First, the hanging member 12 is bent upward through the V-shaped or U-shaped bent grooves 13 of the flow-down prevention member 11. Then, the flow-down prevention member 11 is submerged in the vertical hole 16 of the block 15, the hook portion 14 is hooked on the upper edge of the vertical hole 16, and the filler flow-down prevention device 10 is fixed to the block 15. Next, a filler such as mortar is packed. The filler adheres to the peripheral wall of the vertical hole 16. Further, since the filler has a viscosity, it will not flow down even if there is some gap between the vertical hole 16 and the flow-down prevention member 11. Further, when it is necessary to arrange the horizontal reinforcing bars, the horizontal reinforcing bars may be arranged in the reinforcing groove 17 and the reinforcing groove 17 may be filled with a filler such as mortar. Since the mortar in the vertical hole 16 does not flow down by the flow-down prevention member 11, the strength of the block wall due to the reinforcement does not decrease. If the horizontal reinforcing bar is not necessary, a block without the reinforcing bar groove 17 is used, but the present invention is applicable even in this case.

Next, a description will be given of a filler flow-down prevention tool for a block hole according to a second embodiment of the present invention. FIG. 2 is a perspective view of a filler flow-down preventive device for a block hole according to a second embodiment of the present invention. As shown in FIG. 2, a filling material flow prevention member 18 for a block hole according to a second embodiment of the present invention is made of the same material as the filling material flow prevention device 10 shown in FIG. It is formed as a mesh to serve as the flow-down prevention member 19 (the mesh is shown only partially). The other configurations are the same as the configurations of the filler flow prevention tool 10, and therefore, the same reference numerals are given and the description thereof is omitted. The method of using the filler flow-down prevention tool 18 is the same as that of the filler flow-down prevention tool 10 shown in FIG. 1, but since the flow-down prevention member 19 is a mesh, it is possible to reduce the weight. Moreover, since the filler such as mortar has a viscosity, it does not flow down even if the flow-down prevention member 19 is a mesh.

Next, a description will be given of a filler flow-down prevention tool for block holes according to a third embodiment of the present invention. FIG. 3 is a perspective view of a blocking material filler downflow preventer according to a third embodiment of the present invention. As shown in FIG. 3, a filler flow-down prevention tool 20 for a block hole according to a third embodiment of the present invention uses the same material as the filler flow-down prevention tool 10 shown in FIG. It is formed into a rectangular shape to serve as the flow-down prevention member 21 in consideration of convenience during transportation. The other configurations are the same as the configurations of the filler flow prevention tool 10, and thus the same numbers are given and the description thereof is omitted. Since the filler downflow preventer 20 has the downflow prevention member 21 formed in a rectangular shape, a large gap is formed between the downflow prevention member 21 and the vertical hole 16 shown in FIG. 1. However, due to the viscosity of the filler of the mortar, the downflow occurs from this gap. There is nothing to do.

Next, a filler flow-down preventive for block holes according to a fourth embodiment of the present invention will be described. FIG. 4 is a perspective view of a filler flow-down preventive device for a block hole according to a fourth embodiment of the present invention. As shown in FIG. 4, a filling material downflow prevention device 22 for a block hole according to a fourth embodiment of the present invention is made of the same material as the filling material downflow prevention device 10 shown in FIG. The flow-down prevention member 21 of the filler flow-down prevention device 20 is formed into a mesh to form a flow-down prevention member 23 (the mesh is shown only partially). Other configurations are the same as the configurations of the filler flow prevention tool 10, and therefore, the same reference numerals are given and the description thereof is omitted. The method of using the filler flow prevention tool 22 is the same as the method of using the filler flow prevention tool 20 shown in FIG. The fact that the filler such as mortar does not flow down from the mesh is the same as that of the filler flow prevention tool 18 shown in FIG.

Next, a description will be given of a filler flow-down prevention tool for a block hole according to a fifth embodiment of the present invention. FIG. 5 is a perspective view showing a process of using the filler flow-down prevention tool for a block hole according to a fifth embodiment of the present invention. As shown in FIG. 5, the filler downflow preventing tool 24 for the block hole according to the fifth embodiment of the present invention uses the same material as the filler downflow preventing tool 10 shown in FIG. A wide hanging member 25 was used without using the four hanging members 12, and the hooking portion 26 had a size corresponding to the width of the hanging member 25. Two hanging members 25 are provided at the base of the flow prevention member 28. The fold groove 13 shown in FIG. 1 is a longer fold groove 27. The size and shape of the downflow prevention member 28 were formed to be substantially the same as the downflow prevention member 11 shown in FIG.

The method of using the filler downflow prevention device 24 is substantially the same as the method of using the filler downflow prevention device 10 shown in FIG. 1, except that the hook portions 26 of the two suspension members 25 are blocked. The filler downflow preventing device 24 is fixed to the vertical hole 16 by being hooked on the edge of the vertical hole 16. Although the number of the hanging members 25 is two, since the hooking portion 26 has a width, the hooking portion 26 does not move vertically even if a filling material such as mortar is packed in the vertical hole 16 provided with the filling material downflow stopper 24. It does not fall off the edge of the hole 16 and fall.

Although the filler run-down preventive tool 10, 18, 20, 22, 24 is made of a synthetic resin material such as polypropylene or vinyl chloride, a metal material may be used.
