Description

  The aspect of this invention is related with the sealing method between the floor part and wall part in a bathroom washroom.

  In recent years, bathroom washing places where a caulking material for preventing the outflow of water to the outside is provided between the floor and the wall.

  Patent Document 1 describes a bathroom structure in which a caulking material for waterproofing is provided in a gap between a concave portion of a wall receiving groove portion of a floor surface material and a wall surface material.

  In the bathroom structure provided with such a caulking material, the caulking material is injected into the gap from above the gap between the recess of the wall receiving groove of the floor surface material and the wall surface material. In other words, the supply means for supplying the caulking material is designed to inject the caulking material in a state of being disposed above the gap between the recess and the wall surface material.

JP2013-209853A

  However, in such a bathroom structure, if the caulking material is injected in a state where the supply means is disposed above the gap between the recess and the wall surface material, the gap is difficult for the bathroom builder to see. . As a result, variations may occur in the amount of caulking material injected into the gap depending on the installer. When the injection amount varies, there may be a situation where the caulking material does not sufficiently reach the lower part of the gap. If the caulking material does not arrive sufficiently below the gap, the thickness of the caulking material in the vertical direction will be insufficient. When the thickness of the caulking material is insufficient, the contact area of the caulking material that comes into contact with the concave portion or the wall surface material forming the gap is reduced. When the contact area of the caulking material with respect to the concave portion or wall surface material becomes small, the adhesive force of the entire caulking material with respect to the concave portion or wall surface material decreases. As a result, when an external force is applied to the caulking material, the caulking material is peeled off from the recess or the wall surface material, which may cause a sealing failure.

  The present invention was made based on recognition of such a problem, and in the gap between the floor portion and the wall portion, it is possible to suppress the thickness shortage in the vertical direction of the caulking material and prevent the occurrence of a sealing failure. It aims at providing the sealing method between the floor part and wall part in a bathroom washroom.

The first invention is supplied from a caulking material supply nozzle to a gap between the groove and the wall in a state where a wall forming a standing wall of the bathroom is inserted into a groove provided on the floor of the bathroom washing area. A method for sealing between a floor portion and a wall portion in a bathroom washing place, wherein at least a part of a coking material supply port provided at a tip of the coking material supply nozzle is located in the gap. As described above, at least a part of the caulking material supply nozzle is inserted into the gap, and the caulking material is injected while moving the caulking material supply nozzle along the gap. It is a sealing method between a wall part.
According to the sealing method between the floor portion and the wall portion in this bathroom washing area, the caulking material supply nozzle is inserted into the gap so that at least a part of the caulking material supply port is located in the gap between the groove portion and the wall portion. The caulking material is injected while moving the caulking material supply nozzle along the gap. As a result, the caulking material can be injected into the gap, so that the caulking material can be more reliably injected down to the gap. Therefore, in the gap between the floor portion and the wall portion, the caulking material can be prevented from being insufficient in thickness in the vertical direction, and water can be prevented from flowing out of the room at the bathroom washing place.

In a second aspect based on the first aspect, the caulking material supply nozzle has a flat cross section, the caulking material supply port has a flat shape, and the longitudinal direction of the cross section indicates the longitudinal direction of the caulking material supply port. It is a sealing method between the floor part and the wall part in the bathroom washing place which is substantially parallel to the direction.
According to the sealing method between the floor portion and the wall portion in this bathroom washing area, the cross section of the coking material supply nozzle and the coking material supply port are flat, and the longitudinal direction of the cross section is the longitudinal direction of the coking material supply port. It is substantially parallel to the direction. Accordingly, the caulking material supply nozzle can be inserted into the gap between the floor portion and the wall portion while ensuring the area of the caulking material supply port. Therefore, even when the size of the gap between the floor portion and the wall portion is small, the caulking material supply unit can be inserted into the gap while suppressing the pressure loss due to the coking material supply port.

According to a third aspect of the present invention, in the first or second aspect, the caulking material supply port has a component in which the discharge direction of the caulking material has a component opposite to the moving direction of the caulking material supply nozzle. It is a sealing method between a floor part and a wall part in a bathroom washing place characterized by injecting the caulking material.
According to the sealing method between the floor portion and the wall portion in this bathroom washing area, the caulking material supply port is caulked to the gap between the floor portion and the wall portion in the direction opposite to the moving direction of the caulking material supply nozzle. Inject the material. Thus, the caulking material can be thickly injected into the gap in the vertical direction of the gap. Therefore, in the gap between the floor portion and the wall portion, the caulking material can be prevented from being insufficient in thickness in the vertical direction, and water can be prevented from flowing out of the room at the bathroom washing place. Moreover, it can suppress that the injected caulking material prevents the movement of the caulking material supply nozzle from this. Therefore, workability in the caulking material injection work of the bathroom contractor is improved.

In a fourth aspect based on any one of the first to third aspects, the caulking material supply nozzle has an insertion restricting portion for restricting an insertion amount of the caulking material supply nozzle into the gap, and the insertion restriction It is a sealing method between a floor part and a wall part in a bathroom washing place characterized by injecting the caulking material while moving the caulking material supply nozzle in a state where the insertion amount regulates the insertion amount.
According to the sealing method between the floor portion and the wall portion in the bathroom washing area, the caulking material supply nozzle has an insertion restriction portion that restricts the amount of insertion of the caulking material supply nozzle into the gap between the floor portion and the wall portion. . From this, the insertion control part can suppress that a caulking material supply nozzle is inserted deeply into the clearance gap between a floor part and a wall part. That is, the insertion restricting portion can prevent the caulking material supply port from being blocked by the bottom surface of the gap. Therefore, workability in the caulking material injection work of the bathroom contractor is improved.

  According to the aspect of the present invention, in the gap between the floor portion and the wall portion, the thickness of the caulking material in the vertical direction can be suppressed, and the occurrence of a seal failure can be prevented. A sealing method is provided.

FIG. 5 is a schematic partial cross-sectional view showing an operation of inserting the caulking material supply unit into the gap between the floor and the wall in the bathroom washing area of FIG.
FIG. 6 is a schematic partial cross-sectional view showing the operation of injecting the caulking material into the gap between the floor portion and the wall portion in the bathroom washing area of FIG.
FIG. 5 (a) is a schematic partial cross-sectional view showing the operation of inserting the caulking material supply unit into the gap between the floor and the wall in the bathroom washing area of FIG. FIG.5 (b) is XX sectional drawing in Fig.5 (a).
FIG. 6 (a) is a schematic partial cross-sectional view showing the operation of pouring the caulking material into the gap between the floor and the wall in the bathroom washing area of FIG. FIG. 6B is a YY cross-sectional view in FIG.
The sealing method between the floor 6 and the wall 8 will be described with reference to FIGS.

  As shown in FIG. 4, first, the wall portion 8 is inserted into the groove portion 42. When the wall portion 8 is inserted into the groove portion 42, a gap IS is provided between the wash field inner side surface 44 of the groove portion 42 and the wall portion 8.

  Next, as shown in FIG. 5A, at least a part of the caulking material supply unit 66 is inserted into the gap IS. The caulking material supply nozzle 60 has an insertion restricting portion 70. The insertion restricting portion 70 is provided, for example, at an inner portion where the caulking material supply nozzle 60 is bent, and an outer surface portion of the bent inner portion corresponds to the insertion restricting portion 70. The insertion restricting portion 70 abuts the upper surface of the floor main body 40 of the floor portion 6 to restrict the amount of insertion of the caulking material supply portion 66 into the gap IS. From this, the insertion control part 70 can suppress that the caulking material supply part 66 is inserted deeply into the gap IS. That is, the insertion restricting portion 70 can prevent the caulking material supply port 68 from being blocked by the bottom surface 48 of the gap IS. Therefore, workability in the caulking material CK injection work of the installer of the bathroom unit 100 is improved.

  As shown in FIG. 5B, when at least a part of the caulking material supply unit 66 is inserted into the gap IS, at least a part of the caulking material supply port 68 is located inside the gap IS. At this time, the caulking material supply unit 66 is inserted into the gap IS such that the direction of the caulking material supply port 68 faces the end 72 of the gap IS. In other words, the coking material supply unit 66 is not inserted into the gap IS so that the direction of the coking material supply port 68 is substantially perpendicular to the bottom surface 48 of the gap IS. In the present specification, “the direction of the caulking material supply port” refers to the direction in which the coking material is discharged from the coking material supply port 68.

  Next, as shown in FIG. 6A, by operating the coking material supply means 56, the coking material CK filled in the caulking material supply means main body 58 is injected into the gap IS. At this time, since at least a part of the caulking material supply port 68 is located inside the gap IS, the caulking material CK is injected below the gap IS. At this time, the line of sight of the installer is, for example, an arrow B1 shown in FIG. Thus, the installer can perform the operation of injecting the caulking material CK while visually confirming the state where the caulking material supply nozzle 60 is inserted into the gap IS. Therefore, workability | operativity in the injection | pouring operation | work of the caulking material CK to the clearance gap IS improved.

  As shown in FIG. 6B, the coking material supply means 56 is moved in the direction of the arrow A1 along the clearance IS while the caulking material CK is injected into the clearance IS. It is preferable to keep the moving speed for moving the caulking material supply means 56 as constant as possible. At this time, since the direction of the caulking material supply port 68 has a component opposite to the moving direction of the caulking material supply unit 66, the caulking material CK is directed in the direction opposite to the moving direction of the coking material supply unit 66. And injected into the gap IS. From this, it can suppress that the injected caulking material CK prevents the movement of the caulking material supply part 66. Therefore, workability in the caulking material CK injection work of the installer of the bathroom unit 100 is improved. Further, when the direction of the coking material supply port 68 is directed to the movement direction of the coking material supply unit 66, the coking material CK supplied from the coking material supply port 68 is moved by the coking material supply unit 66 in the gap IS. There is a risk of being pushed in the direction. As a result, the caulking material CK may be applied to a position unexpected by the installer. On the other hand, since the direction of the caulking material supply port 68 of the present embodiment has a component opposite to the moving direction of the caulking material supply unit 66, this can be suppressed. That is, the caulking material CK can be accurately injected into the gap IS, and the caulking material CK can be applied to the gap IS without waste.

  From the above, according to the sealing method of the gap IS between the floor 6 and the wall 8 in the bathroom washing area 2 of the present embodiment, the caulking is performed so that at least a part of the caulking material supply port 68 is located in the gap IS. At least a part of the material supply unit 66 is inserted into the gap IS, and the coking material CK is injected while moving the coking material supply unit 66 along the gap IS. As a result, the caulking material CK can be injected into the gap IS, so that the caulking material CK can be injected below the gap IS. Therefore, in the gap IS, it is possible to suppress a shortage of the thickness of the caulking material CK in the vertical direction, and to prevent water from flowing out of the bathroom unit 100 in the bathroom washing place 2.
