特開2005−36563号公報JP 2005-36563 A

しかしながら、先に提案された防水床パンは、施工時に生じる反り及び捻れなどの変形について考慮されていない。即ち、作業員は、防水床パンを施工現場の壁に立てかけて裏面に脚部材を取り付ける。このとき、防水床パンは、壁パネル、浴槽及び入浴者による厚み方向への荷重とは異なり、壁に立てかけられたときの自重によって、反り及び捻れなどの変形が生じるおそれがある。このような変形状態にあっては、脚部材が取り付け難く、また、脚部材が取り付けられたとしても変形状態が残ることとなる。   However, the previously proposed waterproof floor pan does not take into account deformations such as warping and twisting that occur during construction. That is, the worker puts the waterproof floor pan against the wall of the construction site and attaches the leg member to the back surface. At this time, unlike the load in the thickness direction by the wall panel, bathtub, and bather, the waterproof floor pan may be deformed such as warping and twisting due to its own weight when leaning against the wall. In such a deformed state, the leg member is difficult to attach, and even if the leg member is attached, the deformed state remains.

詳述すると、四角形は、辺の長さが決まっても角の大きさが決まらないため、形が保持され難い。そのため、補強用リブが四角格子状に突設されるのみでは、四角形の角の大きさが変わるような反り及び捻れなどの変形に対して弱く、図5に示すように、従来の防水床パン9は、裏面90の凹部91が、裏面視長方形から菱形に潰れるおそれがある。   More specifically, the shape of the quadrangular is difficult to maintain because the size of the corner is not determined even if the length of the side is determined. Therefore, if the reinforcing ribs are only projected in the form of a square lattice, they are vulnerable to deformation such as warping and twisting that change the size of the square corners, and as shown in FIG. 9, the concave portion 91 of the back surface 90 may be crushed from a rectangular shape in the back surface view to a rhombus.

このような問題を解消するには、工場管理の下、防水床パンが変形しないように脚部材を取り付けておき、これを施工現場に運ぶか、又は、補強用リブの厚み寸法を大きくするなどの工夫が必要となる。しかし、前者は、施工現場への運搬が困難であり、後者は、成形収縮によるヒケが生じて外観不良となるおそれがある。   To solve this problem, install the leg member so that the waterproof floor pan does not deform under factory management, and transport it to the construction site, or increase the thickness of the reinforcing rib. Need to be devised. However, the former is difficult to transport to the construction site, and the latter may cause a sink due to molding shrinkage, resulting in poor appearance.

本発明はかかる事情に鑑みてなされたものであり、本体の裏面にリブが四角格子状に突設され、このリブにより仕切られる複数の凹部のうち、所定の凹部に、脚部材を取り付けるためのボス部と、対角線上にあるボス部を繋ぐように突設させ、凹部を本体の裏面側から見て三角形状となるように分割するためのリブとを備えることにより、四角格子状に形成される補強用リブの厚み寸法を増やすことなく、四角形の角の大きさが変わるような反りや捻れなどの変形に対する強度が確保され、これらの変形を生じさせることなく現場での脚部材の取り付けができる防水床パンを提供することを目的とする。   The present invention has been made in view of such circumstances, and ribs are provided on the back surface of the main body so as to project in a square lattice shape, and a leg member is attached to a predetermined recess among a plurality of recesses partitioned by the rib. By forming a boss part and ribs for projecting so as to connect the boss part on the diagonal line and dividing the concave part into a triangular shape when viewed from the back side of the main body, it is formed in a square lattice shape. Without increasing the thickness of the reinforcing ribs, the strength against deformations such as warping and twisting that change the size of the square corners is secured, and the leg members can be attached on-site without causing these deformations. An object of the present invention is to provide a waterproof floor pan that can be used.

Moreover, a plurality of recesses are formed on the back surface by intersecting the ribs. In addition, among the plurality of recesses, some of the recesses are formed by forming a boss portion having a diameter larger than the thickness dimension of these ribs at the intersection of the first rib and the second rib forming the corner portion. The leg member can be attached via the boss.

た、脚部材取付用の凹部は、第3リブが、対角線上にあるボス部を繋ぐように突設され、本体の裏面側から見て三角形状に分割することによって、四角形の角の大きさが変わるような反り及び捻れに対する強度を備える。詳述すると、三角形は、辺の長さが決まると角の大きさも決まることとなるため、形が保持され易く、反り及び捻れなどの変形に対する強度を有している。本発明に係る防水床パンは、この三角形の性質を利用することによって、余分な力を用いることなく形を安定させている。
更にまた、本発明に係る防水床パンにあっては、第3リブの一部が、裏面側に開口する筒状としてあることによって、脚部材取付用の凹部に取り付けられる脚部材の脚ボルトが進退する場合の調整代を確保している。
