Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a construction method for disposing a Japanese style toilet on the floor.

(Prior Art) Conventionally, a Japanese-style toilet has been installed on the floor by the following construction method, for example.

(A) First, after providing an opening in the deck plate and temporarily fixing a mold having a size corresponding to the toilet installation hole in the opening,
Pour concrete for the base slab onto the top of the deck plate.

(B) After that, when the concrete is solidified and the base slab is formed, the form is removed to form an opening for inserting a toilet (a toilet bowl mounting hole).

(C) After that, a support frame that doubles as a fireproof cover of the toilet is provided in this opening, and the support frame supports the lower surface of the water passage step of the toilet to be inserted later and seals the gap between this support frame and the toilet. Provide materials.

(D) Further, the drain port of the toilet is connected to the pipe connector provided at the lower end of the support frame, and the pipe is connected to the pipe connector.

(E) On the other hand, on the base slab on the outer periphery of the support frame, after filling with mortar for fixing the support frame, a water leakage prevention layer is provided, and cinder concrete or mortar is further provided on the waterproof layer. After filling, a finishing layer is applied and a series of construction work is completed.

(Problems to be Solved by the Invention) However, the conventional method of constructing a Japanese style toilet has the following problems.

(1) First, a series of steps such as attaching a supporting frame to the opening in step (c), attaching a Japanese-style toilet to this supporting frame, and applying a non-drying sealing material to the gap between the Japanese-style toilet and the supporting frame It is troublesome to carry out the work sequentially at the construction site, and if possible, if a series of these work can be performed collectively at the construction site, the efficiency of the construction work can be improved.

(2) Next, when mounting the Japanese-style toilet on the support frame in the same step (c), the mounting height is determined by the height position of the support portion of the support frame, so it is difficult to finely adjust the height of the toilet. Becomes

(3) When connecting the pipes in step (d),
Since the position of the pipe connector is determined by the mounting position of the support frame, that is, the opening position provided in the base slab, subsequent pipe connection becomes difficult unless the series of operations for the pipe position is performed accurately.

(4) In the step (e), the work is complicated in the step of providing the mortar and the preventive layer on the base slab, and then providing the mortar again and then applying the finishing layer.
In addition, the work area is wide, and simultaneous construction with the floor slab is required. Therefore, the work is troublesome, the work efficiency is poor, and the cost is increased.

Therefore, the present invention has been made to solve the conventional problems, and the purpose of the present invention is to quickly and easily install a Japanese-style toilet bowl, and to adjust its height and to easily connect pipes. It is to provide a method of constructing a Japanese style toilet that can be performed at low cost.

(Means and Actions for Solving the Problems) In order to solve the above problems, a method for constructing a Japanese-style toilet according to the present invention is such that a predetermined position on the outer peripheral portion of the Japanese-style toilet 5 is provided on a fireproof cover 6 having a substantially box shape. Is supported by the upper opening, and the Japanese-style toilet bowl 5 is placed at a predetermined position on the outer periphery of the fireproof cover 6.
The height adjusting mechanism 12 is provided, and a through hole 6i for connecting the drain outlet 13a of the Japanese-style toilet 5 to the pipe 15 is provided at the bottom of the height adjusting mechanism 12 by a predetermined dimension from the outer diameter dimension of the drain outlet 13a. While forming the toilet unit 3 formed to be large, the floor slab 4a is provided with an opening 4c penetrating up and down, and a step 4d is formed on the peripheral edge of the opening 4c, and the opening 4c is formed in the opening 4c. While adjusting the height of the toilet unit 3 by the height adjusting mechanism 12 and inserting the drain port portion 13a in conformity with the pipe 15, the predetermined position 6g of the fireproof cover 6 is supported, and the opening is formed. The gap between the stepped portion 4d of the portion 4c and the toilet unit 3 is filled with the fixing material 18.

According to such a construction method, if the toilet unit 3 is manufactured in advance in the factory, it is not necessary to sequentially perform the respective mounting work of the toilet, the fireproof cover, etc. at the construction site, and the toilet units are collectively mounted as a unit. Therefore, the construction can be speeded up and facilitated.

Further, when the toilet unit 3 is attached to the unit support frame 2, the height can be easily adjusted by the height adjusting mechanism 12.

Furthermore, since the through hole 6i provided in the fireproof cover 6 is larger than the outer diameter of the drainage port 13a of the toilet bowl 5, there is a margin in setting the position of the drainage port 13a and the connection position of the pipe 15. Therefore, the piping can be easily connected.

Furthermore, it is not necessary to provide a floor such as a waterproof layer on the substrate slab after inserting the toilet bowl, and therefore, if it is provided at the opening, then the unit toilet bowl can be installed at any time, and therefore the toilet bowl can be installed on the floor. It can be performed independently of the formation of the slab, and thus the working efficiency can be further improved.
