DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention aims to improve the ease and accuracy of tile work by allowing tile craftsmen to adjust the core and height of drainage fittings themselves, and to cope with the era of lack of skilled workers. In addition, eliminating the need for redo work by allowing the construction error of piping work to be larger than before, and
The present invention relates to a floor drainage device that enables a concrete drainage method for floor drainage devices, saves labor and shortens the construction period, and contributes to a reduction in construction costs.

2. Description of the Related Art Conventionally, when floor tiles are to be applied to bathrooms and toilets, prior to the work, the layout of the tiles and the gradient of the floor are examined and written in a construction drawing, and drainage is performed in accordance with the tile layout and the floor gradient. Determine the core and height of the bracket. Prior to concrete work, a drainage sleeve is attached to that position of the formwork and a concrete slab is struck. After removing the formwork, the core and height are set on the concrete slab, and the floor drainage device is fixed with mortar. Next, perform waterproofing work and hit waterproofing press concrete, and finally the tile craftsman measures the inside dimensions of the wall and the core size and height of the drainage fittings, confirms it, the tile splitting of the construction drawing and the floor slope, and then floor tiles Is affixed. In general, there is a permissible construction error in the construction work. In this case, too, the legal dimensions in the wall and the core dimensions and height of the drainage metal measured prior to the tile application are not included in the construction written at the beginning. It is rare that the size of the drawing matches the dimension of mm, and an error of about 10 mm has been allowed. This error was adjusted by a skilled tiler by changing the width of the tile joint and by changing the thickness of the base mortar, so that the finishing was finished with high precision and accuracy. However, recently, the number of skilled tile craftsmen has decreased, and unit construction methods in which several tiles are pasted on paper at a factory to bring them to the site have become widespread in order to save labor and shorten the construction period. It is difficult to change on site, and large tiles, large tile-shaped stones and square drainage fittings are often used, so the number of joints is reduced, and construction errors at the time of tile application The drainage fittings are not aligned with the tile cores, the tiles are distorted, and there are many unsightly ones.Also, many of the drainage is poor because the floor gradient is not properly removed. Was. Therefore, if there is an unadjustable construction error at the time of applying the tiles, remove the waterproofing concrete, remove the waterproofing material, attach the fixed mortar, and remove the drainage device for accurate and clean finishing. Adjusting the position, re-installing the drainage equipment, redoing the waterproofing work, hitting the waterproof holding concrete, and then performing the so-called redoing work of attaching tiles. This would be a problem because it would be unnecessarily time-consuming and expensive because it would be a rework to re-introduce workers other than the tile craftsman, such as a climber, a waterproofer, and a plumber. For roof drains, which are similar drainage hardware, concrete pouring methods are generally used to shorten the construction period and save labor. In the case of concrete pouring methods, however, construction errors can be reduced to about 10 mm. Due to the difficulty, it was rarely adopted for indoor floor drainage.

[0003]

SUMMARY OF THE INVENTION The present invention aims to improve the ease and accuracy of tile work by allowing a tile craftsman to adjust the core and height of a drainage fitting by himself. In order to eliminate the need for redoing work by allowing the construction error of plumbing work to be larger than before, and
It aims to contribute to the reduction of construction costs by enabling the concrete drainage method for floor drainage equipment, saving labor and shortening the construction period.

Means for Solving the Problems Now, the structure will be described. A ring-shaped waterproof plate 11 and a plurality of driving anchors 10 provided on the back side thereof are provided on the upper part of the drainage device main body 1 for height adjustment. The resin core adjusting lid 2 which is appropriately larger in size than the outer diameter of the connection pipe 5 and can be easily drilled with a tool at a construction site can be screwed in. Further, the driving spacer 17 can be attached to the lower drain port. A height adjusting connection pipe 5 in which a drainage metal frame 6 into which a drainage plate 7 is fitted is screwed into an upper portion is prepared separately. Inside the height adjusting connection pipe 5, an inverted odor stopper 8 and an outer odor stopper 9 of an inverted bowl type are fitted. The outside of the connection pipe 5 for height adjustment is threaded, and a fixing frame 4 is prepared by screwing to fit the thread, and a plurality of fixing screws 3 are provided. The configuration is as described above.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In this embodiment, when used, (a) after attaching a driving spacer 17 to a lower part of the drainage device main body 1, a drainage pipe core 18 is shown in the construction drawing. Adjust the height of the waterproof pan 11 to the concrete slab 16
The drainage device body 1 is fixed according to the scheduled upper end height of the
Driving into concrete slab 16. (B) After the construction of the waterproof layer 15, the waterproof holding concrete 14 is struck so that the core adjusting cover 2 on the upper surface of the drainage device main body 1 can be seen. (C) The tile craftsman performs the tile splitting after measuring the inside dimensions of the wall, puts out the drainage metal core 19 based on the tile splitting on the upper surface of the core adjusting lid 2, and places the height adjusting connecting pipe 5 at that position. Then, a hole for adjusting the height is inserted into the hole, and the connection pipe for height adjustment 5 is inserted into the hole. At this time, even if the already fixed drain pipe core 18 and the drain metal core 19 are slightly displaced, the core adjusting lid 2 is appropriately large in size. Can be done. (D) Next, by adjusting a screw cut between the outer periphery of the height adjusting connection pipe 5 and the fixed frame 4, the height of the drainage metal frame 6 is adjusted to a predetermined height, and the water gradient of the floor is adjusted. Is adjusted with a mortar 13 and the floor finish tile 12 is stuck. (E) The same effect can be obtained even if the normal bowl 20 is mounted on the floor drainage device 1 without the inverted bowl type odor stopper set in the height adjusting connection pipe 5.

[0006]

As described above, according to the present invention, the tile craftsman can adjust the core and the height of the drainage metal fittings himself when performing the tile work, so that it is possible to improve the ease and accuracy of the tile work by the unskilled worker. In addition, since the construction error of the plumbing work is allowed to be larger than before, it is possible to eliminate unplanned time and costly redo work. And since the construction error of the plumbing work is tolerated more than before, the piping work can be done even by unskilled workers, and the concrete pouring method of the floor drainage equipment becomes possible, which can save labor and shorten the construction period of the work . From these facts, the present invention can greatly contribute to shortening the construction period and reducing the construction cost in response to the era of less skilled workers.
