However, in the conventional water stop structure described above, since the weight of the wall panel is directly applied to the sealing material, there is a problem that the sealing material is easily damaged by the weight. Further, when the waterproof panel or the wall panel is warped, there is a problem that a gap is easily generated in the vicinity of the sealing material and the water stop function is deteriorated.
The present invention has been made to cope with the above-described problems, and an object of the present invention is to provide a water stop structure between a floor and a wall panel that can perform a reliable seal over a long period of time without damaging the sealing material. is there.

To achieve the above object, it features in configuration of the water shut-off structure between floor and wall panels according to the present invention, the engaging projections projecting upward Re et provided on the edge side upper surface of the floor, seal is engaged with the lower end surface provided et Re engagement protrusion and the engagement recess is engageable wall panels, between the lower end surface of the floor edge side top and wall panels with a sealant a water shut-off structure of the floor and wall panels, the central portion in the thickness direction at the lower end face of the wall panel, one of continuously sealing recess for installing the sheet Lumpur material between the engagement recess only set so as to form a recess, a sealing material, is pressed against the lower end face of the wall panel you located on the opening side of the sealing recess when installed in the sealing recess, between the floor and wall panels It is composed of an elastic material to be sealed.

In the water stop structure of the floor and wall panel according to the present invention configured as described above, a sealing recess is provided on the lower end surface of the wall panel, and a sealing material is installed in the sealing recess. Therefore, the entire weight of the wall panel is not applied to the sealing material, and the sealing material is pressed against the contact surface on the floor side and the contact surface on the wall panel side in the state where the sealing material is installed in the sealing recess. Seal the boundary. That is, the wall panel is supported by the floor, and the sealing material is used in the sealing recess, using the elasticity provided by the sealing material, and the edges of the floor located on the opening side of the sealing recess. It pressed against the part side upper surface.

  For this reason, the sealing material is not damaged by the load, and reliable sealing can be performed over a long period of time. For example, when the sealing material is made of a hollow tubular elastic material, its cross-sectional shape can be formed in various shapes such as a circle, an ellipse, and a rectangle. Further, the cross-sectional shape of the sealing material can be matched to the shape of the concave portion for sealing, and one can be formed into a flat shape and the other can be formed into a semicircular shape, or can be formed into a bowl shape. When the sealing material is made of a plate-like elastic material, the sealing material can be rolled up and installed in the sealing recess, or the sealing material can be folded in, for example, a half and installed in the sealing recess. .

Further, according to the water stop structure of the floor and wall panels according to the present invention, since the combined engagement projection into the engagement recess can be formed only by the water stopping structure mounting the wall panels on the floor, Work for assembly becomes easy.

This allows a more reliable seal. The position where the sealing concave portion is provided may be beside the engaging concave portion or may be the upper portion of the engaging concave portion. When the sealing recess is provided beside the engaging recess, when the engaging recess and the sealing recess are formed in a two-stage depth, and the sealing recess is provided above the engaging recess. Is formed with a recess in which the engagement recess and the seal recess are vertically long.

  Furthermore, still another structural feature of the water stop structure between the floor and the wall panel according to the present invention is that a sealing concave portion is provided in the indoor side portion of the engaging concave portion on the lower end surface of the wall panel. According to this, since the sealing material is installed in a portion near the indoor side surface of the floor or wall panel, water does not enter into the depth side of the water stop structure. For this reason, a more preferable waterproof function is exhibited.

  Still another structural feature of the water stop structure of the floor and the wall panel according to the present invention is that the sealing material is composed of a flat surface portion and a curved portion extending curvedly upward from an edge portion of the flat surface portion. The cross-sectional shape is made of a substantially C-shaped material. According to this, reliable sealing can be performed regardless of the size of the size of the sealing recess. For example, when the concave portion for sealing is large, the sealing material seals between the floor and the wall panel by its elasticity while maintaining a substantially C-shaped shape, and when the concave portion for sealing is small, the sealing material The material seals between the floor and the wall panel while being gradually crushed and changing into a shape close to a double fold. Therefore, the size of the recess for sealing can be set so as to correspond to the size between when the sealing material is substantially C-shaped and when the sealing material is folded in half. Increase.
