Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to the leg structure of waterproof pans, bathtubs with washing areas, bathtubs, etc. (hereinafter representatively referred to as "waterproof pans"), and is particularly applicable to wooden buildings. This article relates to a leg structure for waterproof pans that is effective when installed on foundations with relatively low strength, such as floor joists or foam concrete.

(Problems to be Solved by Prior Art and Ideas) Conventionally, as a leg structure of a waterproof pan, a nut c is embedded in a nut case b formed on the back side of a waterproof pan a, as shown in FIG. It is known that the height and level of the waterproof pan a can be adjusted by means of a bolt d screwed into the waterproof pan a.
However, the above-mentioned conventional leg structure of the waterproof pan a is such that the weight of the waterproof pan a, the wall panel that sits on the waterproof pan a, the bathtub, the water put in the bathtub, and the weight of the person are all transferred to the waterproof pan a. Bolt d, which is the leg of bread a
In order to transfer the compressive strength of the bolt head e to the floor surface f, which is the foundation, if the floor surface f is, for example, a wooden joist or a foamed concrete floor surface, the compressive strength of the floor surface f is the same as that of a concrete floor. It is small compared to the surface, etc., and the ground contact area of the bolt head e alone cannot support the above-mentioned waterproof pan a and all the weight on the waterproof pan a, so a wall panel is built on top of the waterproof pan a. When this occurs, the floor surface f may partially dent, resulting in failure to obtain the designed height, or the once leveled level being distorted.

As a means to solve this problem, there is a method (not shown) in which a steel plate or the like is attached to the bolt head e of the waterproof pan a by means such as welding to increase the ground contact area of the bolt d. According to the above, when adjusting the height etc. of the waterproof pan a by rotating the bolt d, the contact area between the iron plate attached to the bolt d and the floor surface f is large, and the frictional resistance becomes large. ,
This resulted in a disadvantage that the bolt d could not be easily turned.

(Means for solving the problem) The present invention was made to solve the above problem, and its gist is that a bolt is screwed into an appropriate number of nuts fixed to the back side by an appropriate means. ,
In a leg of a waterproof pan, etc., whose height and level can be adjusted by rotating the bolt when the head of the bolt is in contact with the floor, (a) the bolt of the bolt is inside. a rising portion formed in a size that ensures a space capable of accommodating the head; (b) a grounding portion that protrudes outward from the lower end of the rising portion and is brought into contact with the floor surface at its lower surface; A grounding plate consisting of a central plate portion extending inward from the upper end of the rising portion, and (d) a female threaded portion formed integrally with the central plate portion or a female threaded member provided separately, is attached to the bolt. , a position where the grounding part is separated from the floor surface to expose the bolt head, and a position where the grounding part is grounded to the floor surface;
The bolt head is movably screwed together with the position where the bolt head is housed inside the rising part.

(Operation and Effects of the Invention) According to the present invention, the ground plate can be kept away from the floor surface when rotating the bolt. At this time, the entire weight of the waterproof pan, etc. is placed only on the head of the bolt, so the frictional resistance when operating the bolt is small, and the bolt can be easily rotated. On the other hand, if you screw the ground plate toward the bolt head side and install it on the floor after completing the bolt adjustment operation, the weight of the waterproof pan etc. will be shared not only by the bolt head but also by the ground plate. Become. In other words, the waterproof pan is now supported on the floor with a wide contact area,
This eliminates the problems that conventionally occur, such as partial depressions in the floor surface or irregularities in the horizontality of the waterproof pan once taken out.

That is, the present invention supports the waterproof pan with two members, the bolt and the ground plate, and supports the waterproof pan etc. only by the bolt with low operating resistance while adjusting the height of the waterproof pan, etc. After the height adjustment is completed, the ground plate is grounded to share the load. By doing this, when the ground plate is grounded to share the load, the waterproof pan, etc. is already supported by the bolts, so the operating resistance at that time is small, and the ground plate Since the female threaded portion or the female threaded member only needs to be rotated relative to the bolt by an amount necessary for the load sharing by the ground plate, the amount of operation can be extremely small.

(Example) Next, an example of the present invention will be described in detail based on the drawings.

As shown in FIG. 2, the leg structure of the waterproof pan 1 of this embodiment includes a bolt 4 screwed into a nut 3 embedded in a nut case 2 provided on the back side of the waterproof pan 1, and It is characterized by consisting of a ground plate 5 screwed together, the ground plate 5 having a truncated conical rising portion 8 formed to a size capable of accommodating the bolt head 7 of the bolt 4 inside; A flange-shaped grounding portion 6 formed to protrude outward from the lower end of the rising portion 8, a center plate portion 9 continuing inward from the upper end of the rising portion 8, and a center plate portion 9 welded to the center plate portion 9. , a nut 10 with a female thread 11 screwed on the inner surface.
The planar shape is as shown in FIG.

When installing the waterproof pan 1 having the leg structure of this example, place the waterproof pan 1 in a predetermined position, turn the bolt 4 to adjust the height and level of the waterproof pan 1, When the adjustment is completed, the nut 12 screwed onto the bolt 4 is tightened toward the nut 3 buried in the nut case 2 to form a double nut, suppressing the rotation of the bolt 4, and adjusting the waterproof pan 1. Maintain the height and horizontal equality. Further, the ground plate 5 screwed into the bolt 4 is screwed downward, and the grounding portion 6 of the ground plate 5 is pressed against the floor surface 13.

According to the leg structure of the waterproof pan 1 in this example, the weight of the waterproof pan 1 and all the weight placed on the waterproof pan 1 is not limited to the bolt head 7 but also to the grounding portion 6 of the ground plate 5.
Since the unit load on the floor surface 13 becomes smaller, even if a wall panel or other object is placed on the waterproof pan 1 after the waterproof pan 1 is installed, the floor surface 13 will not be locally dented. There is no need to adjust the height or level of the waterproof pan 1 once it has been adjusted. Furthermore, the ground plate 5 is screwed onto the bolt 4, and is screwed forward and pressed against the floor 13 after adjusting the bolt 4, so that the bolt 4 and the floor 13 are The ground contact area of the bolt 4 increases, and the bolt 4 can be easily rotated without requiring a large force when rotating the bolt 4.
The height and level of the waterproof pan 1 can be easily adjusted.

In the above embodiment, the ground plate 5 has a grounding portion 6 projecting like a brim, and a bolt 4 disposed inside the grounding portion 6.
a rising part 8 rising up in the shape of a truncated cone with a size capable of accommodating the bolt head 7; a center plate part 9 continuing inwardly from the upper end of the rising part 8; and a nut welded to the center plate part 9. 10, however, the area of the grounding portion 6 is not limited to that of the embodiment, and may vary depending on the material of the floor surface 13, and the material of the waterproof pan 1 or the wall panel placed on it. It may be appropriately selected and designed depending on the weight, etc., and the planar shape may be any suitable shape such as a rectangle instead of a circle. Further, the shape of the rising portion 8 is not necessarily a truncated cone shape, but may be a hexagonal column shape, for example, and the point is that when the ground plate 5 is screwed downward, the bolt head 7 of the bolt 4 It is sufficient that the bolt head 7 has a shape and size that allows the bolt head 7 to be accommodated within the rising portion 8 of the ground plate 5 without being hit by the ground plate 5. Furthermore, it is not essential that the center plate part 9 of the ground plate 5 and the nut 10 be welded together, but may simply be in contact with each other, or may be bonded with an adhesive or the like, or may be caulked. Furthermore, the center plate portion 9 may be formed thickly, and the female thread portion 11 may be screwed directly into the center plate portion 9.
This may be screwed onto the bolt 4. In short, there is a female threaded portion 1 through which the grounding plate 5 can be screwed so that the grounding portion 6 of the grounding plate 5 can be pressed against the floor surface 13.
1 should be formed. In addition, in order to rotate the bolt head 7 of the bolt 4 with a spanner or the like when adjusting the height and level of the waterproof pan 1 by rotating the bolt 4, the ground plate 5 is placed on the floor surface 13. It is necessary that the ground plate 5 be positioned above the bolt head 7 until it is pressed, and that the structure can hold the bolt head 7 in an exposed state.

Furthermore, after installing the waterproof pan 1 at a predetermined position with a predetermined height and level, if you want to prevent the waterproof pan 1 from shifting laterally, cement or the like is applied to cover the bolts 4 as in the conventional method. You can make it exciting, but
The ground plate 5 is removed by screwing a screw (not shown) into the screw hole 14 provided in the grounding portion 6 of the ground plate 5.
The ground plate 5 and the bolt head 7 may be fixed to the floor surface 13, and the ground plate 5 and the bolt head 7 may be fixed to the floor surface 13 by a method such as pouring an adhesive or the like between the ground plate 5 and the bolt head 7. It is also possible to glue them together.
