Description

  The present invention relates to an instrument used to close the upper end of a vertical hole through which a concrete block for building (hereinafter referred to as a block) passes with mortar.

  In Japanese residential areas, blocks are often installed side by side on the boundary line of the site, causing rainwater to accumulate at the bottom of the vertical holes of the blocks, causing mosquitoes. It is said that mosquitoes are infected with diseases such as Japanese encephalitis, malaria, dengue fever and zika fever, resulting in the death of 1 million people worldwide.

  By filling mortar in the vertical holes of the block, it is possible to prevent rainwater from accumulating and generating mosquitoes.

  In order to save mortar, some methods have been used in which mortar is placed on a vertical hole in the block after stuffed with old newspapers.

  In Patent Document 1, a bowl-shaped mortar receiving frame with a hook is attached to a vertical hole of the block, and mortar heads are formed on the top end face of the block, thereby preventing rainwater from accumulating.

  In Patent Document 2, a hole closing plug using a foam material such as expanded polystyrene or expanded polyethylene is packed in the vertical hole of the block to prevent rainwater from accumulating.

  Patent Document 4 is an improvement of the hole closing plug of Patent Document 2, and a metal hole closing tool that can be used repeatedly is attached to the vertical hole of the block to prevent rainwater from accumulating.

  Patent Document 3 proposes a concrete block with a top-end functional structure that has a shape in which the upper end of the vertical hole of the block is closed, and if such a block with no opening at the top is used from the beginning, rainwater will be generated. There is no accumulation.

Japanese Patent Laid-Open No. 10-18655 (FIG. 3) JP 2006-2548 A (FIG. 1) JP2009-19382A (FIG. 2) Utility Model Registration No. 3191191 (FIG. 4)

  Packing mortar in the vertical holes of the block can prevent rainwater from accumulating, but if you pack the mortar to the bottom of the small hole in the mouth, it will not only take time and effort to push it with a stick, but originally There is a problem that wasteful mortar must be packed deep inside the holes that are not necessary. When many blocks are stacked, the vertical hole is extended and this problem becomes more serious.

  The method of putting mortar on top of the block's vertical holes packed with old newspapers can save waste mortar, but it still takes time to pack old newspapers into many vertical holes. At the same time, the problem remains that the construction results for each hole cannot be equalized.

  The method of forming a mortar headboard after mounting a bowl-shaped mortar receiving frame with a ridge described in Patent Document 1 in a vertical hole to prevent the mortar from falling is performed on an existing block. Has a problem that it is a great deal of time and effort.

  Both Patent Document 2 and Patent Document 4 propose to fit an object other than mortar into the vertical hole of the block, and there is a fundamental problem that it is not intended for semi-permanent construction.

  Regarding the concrete block of the top end functional structure described in Patent Document 3, although it can be used for new construction, replacing the already installed block with this is realistic in terms of cost and the like. There is a problem that is impossible. Moreover, when standing up a fence post or the like, there is a problem that construction cannot be performed without a vertical hole.

  In view of the above problems, the present invention provides a device for enabling a long-lasting and easy-to-repair mortar to be packed evenly into each hole of an existing block without waste.

  In order to solve the above-mentioned problem, by attaching a device according to the present invention to the upper end of the vertical hole of the block, it is possible to prevent the mortar from dropping to the bottom of the vertical hole and to use the same size of the device, It becomes possible to make the amount of the mortar constant in a small amount.

  Mortar processing using this tool can be performed not only on newly installed blocks but also on existing old blocks, and the shape can be maintained to the same extent as the durable years of the blocks.

  The instrument can be easily attached to the block, and by using the instrument, it is possible to reduce the labor of filling the hole in the block and filling the hole.

  As described above, by using the device of the present invention, the amount of mortar to be packed in the hole of the block can be minimized, and there is an effect that the cost and working time of the mortar can be reduced.

  By using this device, even for existing block structures, it becomes possible to easily close the vertical hole with DIY, suppress the occurrence of mosquitoes due to rainwater that accumulates in the hole, and the risk of infectious disease infection Not only does this have the effect of reducing the nature, but it also eliminates the danger of dropping small objects into the block holes.

It is a perspective view of the instrument of this invention. It is a perspective view of the block which attached the instrument of this invention. It is a horizontal sectional view of the block which attaches the instrument of this invention. It is a vertical sectional view of a block in the state where the instrument of the present invention was attached. It is a vertical sectional view which shows a mode that the upper surface of the block was covered with the mortar.

  The device of the present invention has an appearance as shown in FIG. 1 and is attached to the block 21 as shown in FIG. The bottom plate portion 11 of the instrument and the hole shape 22 of the block are substantially the same shape.

  Since the hole shape 22 of the block has a slight variation in size, the bottom plate portion 11 is made of a flexible material so that a gap is not generated as much as possible between the bottom plate portion 11 of the instrument and the hole shape 22 of the block. It is desirable.

  The present invention is similar to Patent Document 1 in that a part of the instrument is hooked and supported on the edge of the vertical hole of the block, but in Patent Document 1, a mortar headboard is formed to structurally close the hole. On the other hand, the present invention is different in that the hole is closed only by the mortar packed in the hole by the adhesive force between the mortar 23 and the block 21 inside the hole.

  FIG. 4 is a vertical cross-sectional view of the block with the device of the present invention attached. As shown in this figure, the mortar 23 is poured only on the bottom plate portion 11.

  The arm portion 12 of the instrument needs to be made thin, so that the area where the mortar 23 contacts the inside of the hole of the block 21 is widened, and the mortar 23 is easily adhered to the block 21.

  In the example shown in FIGS. 1 and 2, there are four arm portions 12 with claw portions 13, and the bottom plate portion 11 is suspended.

  After the mortar 23 has been cured, the appliance cannot be taken out and reused. Therefore, the appliance should be manufactured as inexpensively as possible. In addition, it is only necessary that the device keeps its shape only during the period until the mortar 23 is cured.

  As an example of the material of the instrument, in the prototype, the bottom plate portion 11 is corrugated paper, and the arm portion 12 and the claw portion 13 are galvanized wires. The pair of wire arms are connected through a gap in the corrugated paper. Even such a material that looks weak is strong enough to support a small amount of the mortar 23 that can be packed in the upper end of the hole of the block 21, and in the period until the mortar 23 is cured, the moisture of the mortar 23 is absorbed. The cardboard paper did not collapse when smoked. By keeping the bottom plate portion 11 made of corrugated paper slightly larger than the hole shape 22 of the block, the bottom plate portion 11 could be firmly fixed to the hole of the block 21 without a gap.

  When the mortar is filled only in the hole of the block, the nail portion 13 of the instrument is exposed on the surface, and thus the nail portion 13 may be cut off after the mortar has hardened.

  As shown in FIG. 5, if the mortar 23 is applied to the entire upper surface of the block 21 to such an extent that the nail portion 13 of the instrument is hidden, the boundary around the hole becomes inconspicuous and the workmanship is beautiful. However, since the mortar shrinks slightly after curing, it is preferable that the mortar is filled only in the hole and solidified, and then the mortar is applied to the upper surface by finishing.

  The device of the present invention was originally devised for the purpose of filling the hole of the block with mortar, but the structure of this device is also a suspension type for larger ones. As a frame, it can be used in the field of civil engineering and architecture.
