Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for connecting floor pans to each other when the floor pans are divided and formed in a bathroom or the like.

[0002]

[Prior art]

 In unit baths, floor pans are used to form the bathtub installation area and washroom area using a single resin plate. By the way, the bathroom area tends to be large, and it is difficult to mold the floor pan of a large-sized bathroom resin with a single mold because the mold is upsized. It is performed by dividing it into two parts, such as the installation part and the washing part, and then connecting the divided floor pans on site.

As a conventional technique relating to the connection of divided floor pans, Japanese Patent Application Laid-Open No. 1-235737 is disclosed. In this technique, an engaging recess is provided at the connecting portion of one floor pan, an engaging piece is provided at the connecting portion of the other floor pan, the engaging piece is inserted into the engaging recess, and the waterproofing material is engaged. The fitting recess is filled, and the engagement recess and the engagement piece are waterproofed and connected.

[0004]

[Problems to be solved by the device]

 In the above-mentioned conventional technology, when connecting the split floor pans, the engaging recesses and engaging pieces are connected and sealed by hardening the waterproof material, but the hardening and joining action of the waterproof material is exclusively used. Therefore, the strength of the connecting portion is weak and there is a possibility that the waterproof material may be peeled off or cracked.

Therefore, it is also practiced to screw the split connection portion of the floor pan by providing one connection portion with a thick portion corresponding to the length of the screw, and screwing it by raising a screw from the other thin connection portion. In this case, the thickness of the floor pan will be uneven, which may cause problems during floor pan molding, and cracks may occur around the screw holes when tightening the screws. Although it is necessary to provide a standard guide hole for screwing in, it is difficult to align it with the other hole to be connected to this due to the accuracy of both sides, and the construction at the site is troublesome. On the other hand, if the wall thickness of the connecting portion is reduced, there is a high possibility that water leakage will occur from the gap between the screw surface and the screw penetrating portion.

The present invention has been made to solve the above problems. The purpose of the present invention is to connect split floor pans in terms of strength and sealing, and to simplify the connection work. The purpose is to provide a connection structure for split floor pans with excellent workability.

[0007]

[Means for Solving the Problems]

 The means for solving the above problems is to divide a floor pan divided into a bathtub installation part, a wash room part, etc., and superpose them on the upper and lower parts of the individual connection parts of the floor pans formed separately. A flange piece is provided, a screw insertion hole is provided in the upper flange piece, and a lower surface of a portion of the lower flange piece corresponding to the screw insertion hole of the upper flange piece is larger than the screw insertion hole. The protruding part of the mounting part consisting of the cylindrical convex part filled with is screwed through the screw insertion hole of the upper flange piece to the mounting part of the lower flange piece, and the tip of the screw is embedded in the seal material. It is a connection structure of divided floor pans configured as described above. The screw insertion hole is provided with a dish-shaped recess into which the screw head is loosely fitted, and the tubular convex portion of the mounting portion is cylindrical, and the split floor pan has a diameter sufficiently larger than the shaft portion of the screw. Is the connection structure of.

[0008]

[Action]

 According to the above-mentioned means, the flange pieces of the connecting portion can be formed thinly, and the screw connection allows the flange pieces to be connected to each other, and thus the divided floor pans to be connected to each other firmly and securely, while the screws are screwed together. A cylindrical projection is hung on the lower flange piece that passes through, and this part is provided with the sealing material pre-filled and hardened.The screw shaft is screwed into this, so the sealing of the screw part is ensured. Done.

In this case, the lower flange piece has a structure corresponding to the mounting portion 27 and the upper flange piece. A structure corresponding to the mounting hole 39 of the lunge piece is provided.

[0023]

[Effect of device]

 As apparent from the above, according to the present invention, when connecting the divided floor pans, a thin flange portion having the same thickness as that of the floor pan is provided at the connection portion of the floor pans, and the flange portions are screwed to each other. The floor pans are firmly and securely connected to each other, and even though the floor pans are divided, they are almost the same as the integrated floor pan.

In addition, since the lower floor pan is provided with a mounting portion consisting of a convex portion, and this is made into a tubular shape, the sealing material is filled and solidified, and the upper flange piece is screwed to join the sealing material. By screwing into the screw, a high water leakage effect of the screw shaft can be obtained, and a complete countermeasure against water leakage can be obtained.At the same time, the upper half of the mounting hole of the upper flange piece is used as a countersink and the sealing material is injected. Since it is filled, the effect of preventing water leakage from the screw head is also reliable, and a high and reliable sealing effect is obtained for the entire connection.

Furthermore, the convex mounting portion can be pre-filled and filled with a sealing material in a factory or the like and carried into the site for construction, and the mounting portion having the sealing material has a large diameter. Even if there is an error with the mounting hole of the flange piece, it is possible to absorb this, and it is easy to align and screw in the field. Since the bottom is a sealing material, it can be done easily with a small amount of force, field construction is easy and work is easy, and there are effects such as reduction of construction time, efficiency of construction, labor saving and cost reduction.
