[Industrial applications]

 The present invention is a temporary floor for use when constructing a standard type apartment house such as an apartment, which is suitable for draining rainwater or water dripping when pouring concrete. It concerns drainage facilities.

[0002]

[Prior art]

 In recent years, for example, standard type apartments such as condominiums are directly priced to ordinary people who are demanders, so it is essential to reduce the cost of construction in order to suppress the price. Has become an issue. In order to reduce the cost of such condominium construction, various measures have been taken, such as standardization of materials used, unitization, and easy construction by devising the structure, but there is a limit to the cost reduction. is the current situation. Now, when building a condominium like this, if the floor slab is made of concrete, it is well known that concrete is placed in the assembled formwork. At this time, while curing the cast concrete, the water mixed with the concrete drips from the formwork to the floor directly below. Conventionally, if the water dripping from the concrete pouring floor and the drained water such as rainwater blown from the side are left as they are, the floor slab on the floor directly below will be soiled, and the workers will collect them. For example, it is processed by pouring it into the drainage hole of the balcony.

[0003]

[Problems to be solved by the device]

 However, in the conventional drainage work described above, when the collected drainage is poured into the drainage holes of the balcony, the balcony becomes dirty and the balcony has to be cleaned, which is troublesome. Also, for example, if the floor board construction work on each floor is cycled and the construction efficiency is improved by repeating this on each floor, the worker must regularly perform the drainage work. However, there is a problem in that the cost will be interrupted and the efficiency will be hindered and the personnel cost will be increased, and as a result, the low cost of condominium construction will be hindered. The present invention has been made in consideration of the above points, and it is a standard type housing that can streamline drainage work, treat wastewater at low cost, and reduce the cost of construction of standard type housing. The purpose is to provide a temporary floor drainage system used when constructing a house.

[0004]

[Means for Solving the Problems]

 Since the present invention has three or more floors and a plurality of dwelling units are arranged adjacent to each other in order on each floor, a large number of dwelling units are provided continuously in the left-right direction and vertically stacked. Among these many dwelling units, at least the upper and lower dwelling units are temporary floor drainage facilities to be used when constructing standard type apartment houses with the same plan and elevation plan. A temporary opening for material transportation such as formwork panels was formed on the floor slab directly below the floor where concrete was placed, and the lower surface of the opening covered the opening and was provided with a drainage hole. A water collecting gutter is attached, one end of a drain pipe is attached to the drain hole of the water collecting gutter, and the other end of the drain pipe is arranged so as to communicate with the outside of this standard type housing complex. , Further with the water collecting gutter and the lower surface of the opening It is characterized in that the packing material is interposed between.

[0005]

[Action]

 In the temporary floor drainage system used when constructing the standard type apartment house of the present invention, so-called loose drainage or rainwater drips from the floor where the concrete is placed onto the floor slab directly below the floor. When poured, this water flows into the drain pipe from the drainage hole of the water collection gutter, and is drained from the other end of this drain pipe to the outside of the standard apartment house.

[0006]

【Example】

 Hereinafter, the present invention will be described with reference to the embodiments shown in FIGS. Here, for example, description will be given using an example in which a temporary floor drainage facility used when constructing the standard type apartment house of the present invention is applied to a condominium under construction. Prior to that, an example of a condominium to be constructed will be described with reference to FIGS. 2 and 3.

The condominium (standard type apartment house) M shown in FIGS. 2 and 3 is designed to reduce cost. Each dwelling unit J placed in the condominium M is limited to three types, not only the plan but also the elevation plan, but the details are different, and the dwelling units J of exactly the same type from the first floor to the top floor It is configured to overlap. As a result of thorough standardization, simplification, and commonization, the design work of the condominium M is greatly simplified and reduced. In addition, since the number of repetitive works for each unit J and each floor also increases, it is possible to simplify process management and reduce labor costs and site management costs, and improve work efficiency. And improvement of construction accuracy can be expected. Furthermore, by making the equipment, instruments, etc. in each dwelling unit J common, it is possible to purchase these in bulk at one time, and the cost can be reduced. By accumulating these various cost-saving effects, construction cost reduction can be fully realized.

Next, a temporary floor drainage facility used when constructing the standard apartment house according to the present invention shown in FIGS. 1 and 4 will be described. As shown in these figures, a concrete floor slab 1 of a condominium M to be constructed is provided with a temporary opening 2 in advance. A step 2 a is formed at the upper edge of the opening 2. The opening 2 is, for example, a rectangle of about 600 mm × 200 mm in plan view, and is originally provided for transferring materials such as formwork panels from the lower floor to the upper floor. On the lower surface of the opening 2, a drainage facility including a water collecting trough 4 covering the opening 2 and having a drainage hole 3 and a drainage pipe 5 having one end attached to the drainage hole 3 (temporary installation Floor drainage equipment) A is installed.

As shown in FIG. 1, the water collecting trough 4 includes a bottom portion 4a having a substantially rectangular shape in plan view, a rising portion 4b extending upward from a peripheral edge portion of the bottom portion 4a, and an upper end portion of the rising portion 4b. It has a saucer-like shape formed from a flange portion 4c formed along the same. A cylindrical drain hole 3 extending downward is provided at the center of the bottom portion 4a, and the bottom portion 4a has a shape that is gently inclined toward the drain hole 3 with the drain hole 3 as the lowermost portion. There is. Such a water collecting trough 4 is detachably attached to the lower surface of the opening 2 through, for example, an annular packing material 6 arranged along the flange portion 4c with a bolt or the like. The packing material 6 can prevent drainage from leaking between the water collecting trough 4 and the floor slab 1.

As described above, one end of the drain pipe 5 is attached to the lower end of the drain hole 3 of the water collecting trough 4. The drain pipe 5 is made of, for example, a commercially available vinyl chloride pipe, and the drain hole 3 of the water collecting trough 4 is provided in the drain pipe 5 so that drainage does not leak from the connection portion of the water collecting trough 4 and the drain pipe 5. It is in the inserted form. The other end of the drainage pipe 5 is disposed so as to directly drain the drainage pipe 5 to a main drainage gutter of a balcony (not shown).

Next, a method of applying the drainage facility A configured as described above to a condominium under construction will be described. As shown in FIG. 4, when the concrete C is placed on the upper floor (floor where concrete is placed) 7 to form the floor slab 1 of the condominium M, directly below the floor slab 1 already formed. The drainage facility A is attached to the opening 2 of the floor slab 1 on the floor 8.

Then, concrete C is poured into the floor formwork 10 of the upper floor 7 supported by the supporting works 9, 9, .... At this time, a mold 11 is assembled on the floor mold 10 at the place where the opening 2 is to be formed. A crosspiece 11a for forming the stepped portion 2a of the opening 2 is fixed to the back surface side of the frame 11.

Now, when concrete C is placed on the floor formwork 10 on the upper floor 7, water mixed with the concrete C, so-called “soil drainage”, drips onto the floor slab 1 on the floor 8 directly below. Then, the operator collects the water dripping on the floor slab 1 and the rainwater that has entered from the side and pours it into the water collecting trough 4 of the drainage facility A through the opening 2. Then, this water flows into the drain pipe 5 from the drain hole 3 of the water collecting trough 4, and is discharged from the other end (not shown) of the drain pipe 5 to the drain pipe of the balcony.

After that, when the concrete C on the upper floor 7 is cured and a predetermined strength is developed, the floor formwork 10 and the formwork 11 are disassembled, and a predetermined number of support works 9 are left, and another support work is performed. Remove 9. Then, on the upper floor 7, a floor slab 1 similar to the floor 8 directly below is constructed, and a lid member 12 is formed inside the formwork 11. The lid member 12 is to be removed when the opening 2 is used.

Then, the drainage facility A is removed from the floor slab 1 on the floor 8 directly below and is diverted and attached to the floor slab 1 on the upper floor 7, and the floor slab 1 on the upper floor is formed in the same manner as above. To go.

Further, after removing the drainage equipment A from the floor slab 1, if the closing plate 14 for closing the opening 2 is placed on the step 2 a of the opening 2 as in the floor slab 1 on the lower floor 13. It can be prevented from falling. At this time, since the step portion 2a is provided in the opening portion 2, the closing plate 14 and the floor slab 1 can be flush with each other, and the risk of tripping the operator can be prevented. Then, as shown in FIG. 5, finally, by fitting the lid member 12 into the opening 2 and placing concrete C on the upper surface thereof to close the working opening 2. The floor slab 1 is formed.

By setting a working cycle such that the above-mentioned work is carried out by a predetermined number of workers in sequence for a predetermined number of days, and repeating this construction cycle from the lower floor to the upper floor in each construction floor in sequence. The construction of the floor slab 1 of the condominium M shown in FIGS. 2 and 3 is completed.

In the drainage facility A described above, the operator scrapes water dripping on the floor slab 1 from the upper floor 7 on which the concrete C has been cast to the floor slab 1 on the floor 8 directly below or rainwater that has entered from the side, and the opening When it is poured from 2 into the drainage gutter 4 of the drainage facility A, this water flows into the drainage pipe 5 from the drainage hole 3 of the drainage gutter 4, and from the other end (not shown) of the drainage pipe 5 through the drainage gutter of the balcony. Is discharged to the outside. This will improve the efficiency of the wastewater treatment work.Therefore, set a construction cycle so that a predetermined number of workers will carry out the work in a predetermined number of days in sequence, and carry out this construction cycle sequentially from the lower floors to the upper floors. When repeatedly constructing the floor slab 1 of the Mansion M on the construction floor, there is no need to take the trouble of treating the wastewater as in the conventional method, so that the construction cycle is not interrupted and the construction is efficiently performed. In addition to being able to perform work, the personnel cost can be reduced, which can reduce the construction cost of the condominium M. Moreover, since the drainage facility A can be sequentially diverted to the upper floors, the low cost can be achieved also from this point. Further, since the step portion 2a is provided at the upper edge portion of the opening portion 2, when the closing plate 14 for closing the opening portion 2 to prevent the fall is applied, the closing plate 14 and the floor slab 1 are It is possible to prevent the danger of workers tripping over.

[Effect of device]

 As explained above, according to the temporary floor drainage system used when constructing the standard type apartment house of the present invention, water dripping onto the floor slab on the floor directly below the floor where concrete is placed and from the side When the operator collects the invading rainwater and pours it into the water collecting trough through the opening, this water flows from the drain hole of the water collecting trough into the drain pipe, and is discharged to the outside from the other end of the drain pipe. By doing so, the wastewater treatment work will be more efficient.Therefore, the construction cycle is set so that the workers with a predetermined number of workers will carry out the work in a predetermined number of days in sequence, and this work cycle is carried out sequentially from the lower floors to the upper floors. When repeatedly constructing standard type housing on each construction floor, there is no need to take the trouble of treating wastewater as in the past, so the construction cycle is not interrupted and construction work is performed efficiently. In addition to being able to reduce the personnel cost, it is possible to reduce the construction cost of a standard type housing complex. In addition, by gradually converting this temporary floor drainage system to the upper floors, it becomes possible to further reduce costs.
