Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing an equipment concentration unit that also serves as a form for accommodating equipment piping, heat source equipment and meters for each house in a multi-story apartment such as a high-rise apartment.

[0002]

2. Description of the Related Art Conventionally, equipment centralized units for each house are
In order to facilitate maintenance and inspection of facility piping, gas water heaters, on-off valves and meters that are housed inside, there is a chamber on the corridor side wall of a high-rise apartment, etc. Was there. However, if such a chamber room is constructed with cast-in-place concrete or PC plate at the time of construction of the frame, the execution cost is high because of the labor of the mold for the wall recess and the PC plate production and installation. There was a drawback that Therefore, as an equipment centralized unit for each house which solves such a drawback, one shown in FIG. 7 has been proposed (Japanese Patent Publication No. 61-49582). This equipment concentrating unit is located adjacent to a pair of doors.
Each of them is covered with a pipe cover 54 that covers the corridor side of a wall 53 made of cast-in-place concrete or a PC plate that separates the room 51 from the common corridor 52. A vertical pipe 55, a pair of sewage vertical pipe 56, a ventilation vertical pipe 57, and a gas vertical pipe 58 are accommodated.
Then, after finishing the floors and ceiling slabs of the wall 53 and the corridor 52, 1 with the front surface of the pipe cover 54 exposed.
A pair of gas water heaters 59 is hung on a ceiling slab via a support metal fitting (not shown), and a pair of water meters 60 and gas meters 61 are installed in the pipe cover 54 to correspond to these devices. The vertical pipes are connected by branch pipes 62, 63, 64 for water supply, gas, and hot water supply, each of which has an opening / closing valve provided at an important point. In addition, the horizontal pipes 65, 66, 67 for water supply, gas, hot water branching from the respective branch pipes 62, 63, 64 and the pair of wastewater horizontal pipes 68 have a board 69 fitted in the opening of the wall 53. It penetrates and is guided to each room 51, and supplies tap water, gas, and hot water to each house.

[0003]

However, in the above-mentioned conventional equipment concentration unit, the pipe cover 5 protruding into the corridor 52 is used.
Since the water tank 59 of the gas water heater 59 in the unit is exposed to the outside air or wind, there is a problem that the water heating efficiency deteriorates in the cold season. In addition, the pipe cover 54
Since the width of the corridor 52 is narrowed by the amount of the protruding portion, if the waist wall outside the corridor is made to be a straight line in a plan view, the corridor width will naturally widen, and waste space will be created in places other than the pipe cover part. On the other hand, on the contrary, if the width of the corridor is to be made constant, the waist wall of the pipe cover portion must be made convex in a plan view, and there is a problem that construction of the convex waist wall is troublesome and costly.

Here, the vertical pipes 55 to 58 for water supply, sewage, ventilation, and gas that penetrate the floor and ceiling slabs of the corridor 52 are
Usually, when the slab is reinforced concrete cast in situ, after placing a sleeve for through holes in the formwork, place the slab concrete on the floor and ceiling, and place these vertical pipes in the through holes made after placing. The slab is installed by inserting it into a PC
In the case of a plate, these vertical tubes are inserted through through holes that have been opened in the PC plate in advance at a factory or the like. However, in the former case, the sleeve attached to the formwork is easily displaced and the through hole is often not opened at the specified position, so it is necessary to carry out scrubbing work on the concrete side and alignment on the vertical pipe side. In addition to decreasing efficiency, rainwater will leak to the lower floor from the through hole unless a vertical pipe is installed and the surrounding area is sealed.
Since the pouring of concrete concrete is usually done at once for 3 to 4 floors, vertical pipe and piping work will be postponed, and this piping work may delay the completion of the work when various miscellaneous works are concentrated. There is a problem. On the other hand, in the case of the latter, there is no problem of positional deviation of the through hole and the follow-up work like the former, but there are problems that it takes time and effort to drill holes in the factory, and there is a problem of rainwater leakage similar to the former.

Therefore, the object of the present invention is to construct a unit and a construction procedure based on the idea that a unit containing equipment piping for each house and a heat source device is also used as a mold for the recess of the outer wall of the corridor of the room. By improving the efficiency of the water heater while ensuring the required corridor width without the labor and cost of construction, eliminating the worry of rainwater leakage and slab scavenging work, It is an object of the present invention to provide a method of constructing a facility-concentrating unit that also serves as a formwork, which facilitates alignment and improves work efficiency, and in particular can simultaneously perform frame work and vertical pipe and pipe work and eliminate bottlenecks in construction.

[0006]

Then, the walls and the reinforcing bars of the slab or the beam are arranged in each of the molds. Then, the height of the box becomes the floor height inside dimension of the floor where the concrete should be placed, and the upper end of the vertical pipe penetrating the upper plate projects more than the floor slab thickness of the upper floor.

After the installation of the formwork including the box body is completed, concrete is placed between the side plate of the box body and the recess wall formwork, on the upper plate or between the upper plate and the beam formwork, and in the wall formwork. To set. Thus, the concrete placing, which is the skeleton construction, and the construction of the shared vertical pipes are performed at the same time, and the box that stores the equipment piping is

Therefore, the bottleneck in the construction can be eliminated by the simultaneous construction of the frame and the vertical pipe, and the work efficiency is improved by worrying about rainwater leakage due to the slab through hole for the vertical pipe, scavenging work and position correction of the vertical pipe. At the same time, since the box body is buried in the wall concave portion, a predetermined corridor width can be secured without the labor and cost of construction, and the efficiency can be improved if the water heater is housed in the box body. After that, if necessary, for example, a door is attached to the box body, and a gas water heater, an opening / closing valve, a branch pipe and meters for connecting the common pipe, the gas water heater, and the opening / closing valve to each other are attached to the inside of the box body. . It is also possible to preliminarily mount all of these members in the box body without retrofitting them.

As shown in FIG. 1 (B), the inside of the box body 1 is reinforced by a plurality of lateral reinforcing frames 10 in which angle steel is assembled in a U shape and vertical reinforcing frames 10 at four corners. The end holder 7 is arranged along the outer surface of the reinforcing frame 10, and the gas vertical pipe 5 and the water vertical pipe 4 are fixed by the fixing tools 11 provided horizontally on the left and right of the lateral reinforcing frame 10. At the same time, the front opening is covered with a single-sided door 12, and the exhaust 13 of the gas water heater 6 fixed to the upper part of the box body is opened through a hole 13 (see FIG. 2B) in the upper part of the closed door 12. The mouth 14 is adapted to project. In this embodiment, a gas meter 15 and a water meter 16 are arranged in the lower center of the box body 1, and an inlet side of the gas meter 15 and a gas vertical pipe 5 are a gas branch pipe 18 having a gas cock 17 as an opening / closing valve. The outlet of 15 and the gas water heater 6 are connected to each other by a gas branch pipe 20 having a gas cock 19, and a horizontal gas pipe 21 branching downward and rearward from the gas branch pipe 20 penetrates the rear side plate 3c. And protrudes beyond the wall thickness (see FIG. 2 (B)).

The equipment-concentrating unit of the above-mentioned construction, which also serves as a formwork, is constructed integrally with the body of the building by the following method. First, align the opening of the box 1 with the edge of the corridor.
(Refer to Fig. 4 and Fig. 5) Install the concrete at a predetermined position on the inside of the floor on the floor slab where the concrete should be placed, and connect the female connections 4a, 5a at the lower ends of the water supply and gas vertical pipes 4, 5 in the box body 1, It connects to the water connection on the lower floor protruding from the floor slab and the male connection portions 4b and 5b on the upper end of the gas vertical pipe. Next, the plurality of end holders 7, 7, ... Provided on the outer surfaces of the upper plate 2 and the side plate 3 of the box 1 are attached to
As shown in FIG. 6, one end of a separator 30 formed by cutting both ends of round steel is screwed. Subsequently, the upper plate 2 of the box body 1 is connected to the side frame 31 of the beam via the horizontal separator 30 as shown in FIG.
As shown in FIG. 6, is connected to the back form 32 and the side forms 33, 33 for the recess wall installed so as to surround the side plate 3 from the indoor side via a horizontal separator 30. ,
On both sides of the front opening of the box body 1, a pair of left and right wall formwork 34a,
Connect to 34b. The box 1 and each wall formwork are connected to each other by the well-known method shown in FIGS. 4 to 6, that is, the other end of the separator 30 that is inserted into the wall support form and the supporting structure 35 vertically and horizontally assembled on its outer surface. , The nut 37 through the washer 36. In addition, when the upper plate 2 is flat and has no step portion 8 and the side plate does not have the notch 9, the upper plate is connected via a horizontal separator to the form 39 of the floor slab on the upper floor (see FIG. 5). You can connect to.

Thus, as shown in FIGS. 4 and 5, the lower formwork 40 of the beam forms the same horizontal plane as the step portion 8 of the upper plate 2,
The formwork 39 of the upper floor slab forms the same horizontal plane as the top part of the upper plate 2, the side formwork 31 of the beam and the vertical part of the upper plate 2 face each other, and the beam 38 to be cast forms the box body 1. It is supported by a floor slab through it, and the height of the box body 1 becomes the size within the floor height of the floor where concrete should be placed, and the water pipes passing through the upper plate 2 and the upper ends 4b of the gas vertical pipes 4, 5 The installation of the formwork is completed in a state in which 5b protrudes more than the thickness of the floor slab on the upper floor shown by the broken lines in FIGS. Next, the walls, slabs,
After arranging the predetermined reinforcing bars of the beam, concrete is poured as shown by the cross-section symbols in FIGS. 4 to 6, and the mold is removed after the concrete is hardened. After that, the unconnected gas in the box 1
The water meters 15 and 16 are connected to the branch pipes 18, 20; 23, 26;
28 and the gas water heater 6 are connected, the door 12 is attached to the front surface of the box body 1, and the construction of the equipment concentration unit is completed. Thus, concrete construction and water supply, which is the frame work, gas vertical pipe 4,
The construction of the equipment concentrating unit including 5 is performed at the same time, and the steel box body 1 accommodating the equipment piping and the gas water heater 6 is integrated in a state of being embedded in the body, that is, the recess wall.

Therefore, by simultaneously constructing the skeleton and the equipment centralized unit, vertical pipe work does not follow the skeleton work as in the conventional case and delays in completion, eliminating bottlenecks in construction and deviation of through holes. It eliminates the need for scavenging of concrete and correction of the position of the vertical pipe, which greatly facilitates vertical pipe construction, improves work efficiency, and prevents rainwater from leaking from the through holes to the lower floors. Further, since the box body 1 is surrounded by the recessed wall, the water tank of the gas water heater 6 is not exposed to the outside air or wind in the cold season, the efficiency of the gas water heater 6 is improved, and the corridor 52 is provided. Since the wall and the waist wall become parallel straight lines in the plan view without the protruding portion (see FIG. 7), the corridor can have a predetermined width without labor and cost for constructing the skeleton.

In the above embodiment, the upper plate 2 of the box body 1 is provided with the step portion 8 and the side plates 3a and 3b are provided with the notches 9, respectively, and this portion is used as a part of the beam form. Since the cast beam concrete 38 is supported by the floor slab via the box body 1, the strength of the formwork is increased and the supporting work 35 can be reduced, and the interposition of the box body 1 allows the wall formwork and the upper floor to be suspended. There are advantages that the formwork of the floor slab is reinforced and easy to assemble, and that the space under the beam can be effectively used for the installation of the equipment concentration unit, thus saving space in the building. Also, the water supply,
Since the horizontal pipes 27, 21, 29 for gas and hot water penetrate the side plate 3c at the back of the box 1 and project more than the wall thickness as shown in FIGS. 5 and 6, these horizontal pipes However, there is an advantage that after the concrete is placed, it projects from the wall into the room, which facilitates the subsequent piping work in the room.

The upper plate and the pair of side plates facing each other of the box body of the present invention may be flat without any step or notch unlike the above-mentioned embodiment, and the water supply of the present invention may be used. The branch pipes for gas, hot water, etc. may not have the horizontal pipes penetrating the inner side plates. Even in these cases,
The skeleton work and the vertical pipe work can be performed at the same time, and the box body is embedded in the recessed wall, which simplifies the vertical pipe work and eliminates the bottleneck in the construction, and the rainwater leakage due to the through hole, the scraping work, and the vertical pipe work. It is possible to eliminate the position correction, improve the efficiency of the gas water heater, and ensure the predetermined corridor width without labor and cost for constructing the frame. Further, in the above embodiment, the gas meter and the water meter and each branch pipe are incorporated in the box body,
This can be retrofitted. Further, the vertical pipe of the present invention is not limited to the water supply pipe and the gas vertical pipe of the embodiment, and may be an electric main line pipe or the like. Further, instead of the end holding tool for the separator on the outer surface of the box body of the embodiment, it is possible to directly project the separator on the outer surface of the box body.

[0017]

As is apparent from the above description, the method of constructing the equipment concentrating unit that also serves as the formwork of the present invention is as follows. While vertically extending the common vertical pipe that the upper end penetrates through the upper plate and projects beyond the slab thickness of the building over substantially the entire height of the box, for the outer surface of the box multiple separators or for multiple separators An equipment holding unit is provided by providing an end holder, and the equipment collecting unit is installed on the indoor side on the floor slab so that the opening of the box is aligned with the corridor edge, and the common vertical pipe is installed from the floor slab. The step of connecting to the common vertical pipe of the lower floor projecting, the side plate of the box body, the recess wall formwork installed so as to surround the side plate from the indoor side, the upper plate of the box body ,
Connected to the floor slab or beam formwork on the upper floor via the separator respectively, connect both sides of the opening of the box body to the wall formwork installed along the corridor, and in each of the formwork Placing walls and reinforcing bars for slabs or beams; placing concrete between the side plates and the recessed wall form, on the top plate or between the top plate and the beam form, and in the wall form. And since it has a process to integrate the building frame and the installation centralized unit, the frame work and the vertical pipe work can be performed at the same time, so the vertical pipe work can be facilitated and the bottleneck in the construction can be eliminated, and the recess Hard pipe work is eliminated even in narrow places such as inside walls, and it is possible to improve work efficiency by eliminating rainwater leakage due to through holes, sealing work around through holes, picking work, and vertical pipe position correction. Since the box is embedded in the recess wall, it is suitable for building It is possible to secure a predetermined corridor width without the between and cost.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing an equipment concentration unit that also serves as a form for accommodating equipment piping, heat source equipment and meters for each house in a multi-story apartment such as a high-rise apartment.

[0002]

2. Description of the Related Art Conventionally, equipment centralized units for each house are
In order to facilitate maintenance and inspection of facility piping, gas water heaters, on-off valves, and meters that are stored inside, a recess is provided in the wall on the corridor side of high-rise apartments, etc. Was there. However, if such a chamber room is constructed with cast-in-place concrete or PC plate at the time of frame construction, the construction cost is high because of the labor of the mold for the wall recess and the PC plate production and installation. There was a drawback that Therefore, as an equipment centralized unit for each house which solves such a drawback, one shown in FIG. 7 has been proposed (Japanese Patent Publication No. 61-49582). This equipment concentrating unit is located adjacent to a pair of doors.
Each of them is covered with a pipe cover 54 that covers the corridor side of a wall 53 made of cast-in-place concrete or a PC plate that separates the room 51 from the common corridor 52. A vertical pipe 55, a pair of sewage vertical pipe 56, a ventilation vertical pipe 57, and a gas vertical pipe 58 are accommodated.
Then, after finishing the wall 53 and the floor and ceiling slabs of the corridor 52, a pair of gas water heaters 59 fitted into the openings provided in the pipe cover 54 by projecting the front surface thereof are supported by metal fittings (not shown). It is attached to the ceiling by a pipe, and a pair of water meter 60 and gas meter 61 are installed in the pipe cover 54, and each vertical pipe corresponding to these devices is connected to an important point with an open / close valve to supply water, gas, and hot water. It connects with each branch pipe 62,63,64. Further, the horizontal pipes 65, 66, 67 for water supply, gas, hot water branching from the respective branch pipes 62, 63, 64 and the pair of dirty water horizontal pipes 68 have a board 69 fitted in the opening of the wall 53. It penetrates and is guided to each room 51, and supplies tap water, gas, and hot water to each house.

[0003]

However, since the above-mentioned conventional equipment concentration unit is provided inside the pipe cover 54 which projects into the corridor 52 and is exposed to the outside air and wind, the water supply branch pipe 62 and the hot water supply branch are provided in the cold season. There is a problem that the tube 64 freezes. In addition, as much as the pipe cover 54 projects, the corridor 5
Since the width of 2 becomes narrower, if you try to make the waist wall outside the corridor linear in the plan view, the corridor width will naturally widen and waste space will be created in places other than the piping cover part, while conversely, the corridor width In order to make constant, the waist wall of the pipe cover portion must be made to be convex in a plan view, and there is a problem that construction of the convex waist wall takes time and cost.

Here, the vertical pipes 55 to 58 for water supply, sewage, ventilation, and gas that penetrate the floor and ceiling slabs of the corridor 52 are
Usually, when the slab is reinforced concrete cast in situ, after placing a sleeve for through holes in the formwork, place the slab concrete on the floor and ceiling, and place these vertical pipes in the through holes made after placing. The slab is installed by inserting it into a PC
In the case of a plate, these vertical tubes are inserted through through holes that have been opened in the PC plate in advance at a factory or the like. However, in the former case, the sleeve attached to the formwork is easily displaced and the through hole is often not opened at the specified position, so it is necessary to carry out scrubbing work on the concrete side and alignment on the vertical pipe side. There is a problem that the efficiency decreases and rainwater leaks to the lower floor through the through hole unless a vertical pipe is arranged and the periphery of the vertical pipe is sealed. Further, since the formwork dismantling after placing the concrete concrete is performed after the placing of the concrete on the 3rd to 4th floors is completed, the vertical pipe and piping work will be considerably delayed, and various miscellaneous problems will occur. This plumbing work may delay the completion of the work just before the work is completed. On the other hand, in the case of the latter, there is no problem of positional deviation of the through hole and the follow-up work like the former, but there are problems that it takes time and effort to drill holes in the factory, and there is a problem of rainwater leakage similar to the former.

Therefore, the object of the present invention is to construct a unit and a construction procedure based on the idea that a unit containing equipment piping for each house and a heat source device is also used as a mold for the recess of the outer wall of the corridor of the room. By securing the required corridor width without labor and cost for construction, the freezing of water supply branch pipes and hot water supply branch pipes can be prevented, and there is no worry of rainwater leakage and slab cleaning work. , It is easy to align the vertical pipes to improve work efficiency, especially for the frame work and vertical pipes,
An object of the present invention is to provide a method for constructing an equipment concentration unit that also serves as a formwork, which enables simultaneous piping work and eliminates bottlenecks in construction.

The equipment-concentrating unit of the above-mentioned construction, which is also used as a formwork, is constructed integrally with the body of the building by the following method. First, align the opening of the box 1 with the edge of the corridor.
(Refer to Fig. 4 and Fig. 5) Install the concrete at a predetermined position on the inside of the floor on the floor slab where the concrete should be placed, and connect the female connections 4a, 5a at the lower ends of the water supply and the gas vertical pipes 4, 5 in the box body 1, It is connected to the male connections 4b and 5b at the upper end of the water and gas pipes on the lower floor projecting from the floor slab, and the front both sides of the box 1 are connected to the left and right outer wall forms 34a and 34a. Subsequently, after arranging the reinforcing bars of the wall along the inner surfaces of the box body 1 and the wall formwork, as shown in FIGS. 5 and 6, inside these, a back mold for the recess wall on the back surface of the box body. The frame 32, the side molds 33, the left and right inner wall molds 34b, 34b are arranged, and a plurality of end holders 7, 7 ... Are provided on the outer surface of the side plate 3 of the box body 1, Figure 4
As shown in FIG. 6, a separator 30 formed by cutting screws at both ends of round steel is horizontally inserted from the inner surface side, and penetrates the back mold 32 and the side molds 33, 33 for facing the recessed wall. Then, the nuts 37 screwed on both ends of the separator are tightened to connect the inner and outer molds with a predetermined distance. next,
The upper ends of the wall forms 34a and 34b and the upper plate 2 of the box 1 are connected to the form 39 of the floor slab of the upper floor, and the step 8 of the upper plate of the box 1 and the form 39 of the floor slab are beamed. Lower formwork 40
And slabs and beam rebars are placed in these forms and connected to side forms. In addition, the connection between the box 1 and each wall form,
The well-known method shown in FIGS. 4 to 6, that is, the separator 30 inserted into the wall formwork and the supporting work 35 assembled vertically and horizontally on the outer surface thereof.
The other end is stopped by a nut 37 via a washer 36. Further, when the upper plate 2 is flat and has no step portion 8 and the side plate does not have the notch 9, the upper plate may be connected to the form 39 (see FIG. 5) of the floor slab on the upper floor.

Thus, as shown in FIGS. 4 and 5, the lower formwork 40 of the beam forms the same horizontal plane as the step portion 8 of the upper plate 2,
The formwork 39 of the upper floor slab forms the same horizontal plane as the top part of the upper plate 2, the side formwork 31 of the beam and the vertical part of the upper plate 2 face each other, and the beam 38 to be cast forms the box body 1. It is supported by a floor slab through it, and the height of the box body 1 becomes the size within the floor height of the floor where concrete should be placed, and the water pipes passing through the upper plate 2 and the upper ends 4b of the gas vertical pipes 4, 5 The installation of the formwork is completed in a state in which 5b protrudes more than the thickness of the floor slab on the upper floor shown by the broken lines in FIGS. Next, concrete is placed in the mold as shown by cross-section symbols in FIGS. 4 to 6, and the mold is removed after the concrete is hardened. After that, the unconnected gas and water meters 15 and 16 in the box 1 are connected to the branch pipes 18 and 20; 2 respectively.
3, 26; 28 and the gas water heater 6 are connected, and the door 12 is attached to the front surface of the box 1 to complete the construction of the equipment concentration unit. Thus, the construction of concrete, which is the skeleton work, and the construction of the equipment concentrating unit including the water supply and the gas vertical pipes 4 and 5 are carried out at the same time, and the steel box 1 housing the equipment pipes and the gas water heater 6 is the skeleton. That is, they are integrated in a state of being embedded in the recess wall.

Therefore, by simultaneously constructing the skeleton and the equipment centralized unit, vertical pipe work does not follow the skeleton work as in the conventional case and delays in completion, eliminating bottlenecks in construction and deviation of through holes. It eliminates the need for scavenging of concrete and correction of the position of the vertical pipe, which greatly facilitates vertical pipe construction, improves work efficiency, and prevents rainwater from leaking from the through holes to the lower floors. Further, since the box body 1 is surrounded by the recessed wall, the water supply branch pipe 23 and the hot water supply branch pipe 28 are not exposed to the outside air or wind in the cold season, so that these branch pipes can be prevented from freezing and protrude into the corridor 52. Since the walls (see FIG. 7) are eliminated and the wall and the waist wall become parallel straight lines on the plan view, the corridor can be set to a predetermined width without labor and cost for constructing the skeleton.

In the above embodiment, the upper plate 2 of the box body 1 is provided with the step portion 8 and the side plates 3a and 3b are provided with the notches 9, respectively, and this portion is used as a part of the beam form. Since the cast beam concrete 38 is supported by the floor slab via the box body 1, the strength of the formwork is increased and the supporting work 35 can be reduced, and the interposition of the box body 1 allows the wall formwork and the upper floor to be suspended. There are advantages that the formwork of the floor slab is reinforced and easy to assemble, and that the space under the beam can be effectively used for the installation of the equipment concentration unit, thus saving space in the building. Also, the water supply,
Since the horizontal pipes 27, 21, 29 for gas and hot water penetrate the side plate 3c at the back of the box 1 and project more than the wall thickness as shown in FIGS. 5 and 6, these horizontal pipes However, there is an advantage that after the concrete is placed, it projects from the wall into the room, which facilitates the subsequent piping work in the room.

The upper plate and the pair of side plates facing each other of the box body of the present invention may be flat without any step or notch unlike the above-mentioned embodiment, and the water supply of the present invention may be used. The branch pipes for gas, hot water, etc. may not have the horizontal pipes penetrating the inner side plates. Even in these cases,
The skeleton work and the vertical pipe work can be performed at the same time, and the box body is embedded in the recessed wall, which simplifies the vertical pipe work and eliminates the bottleneck in the construction, and the rainwater leakage due to the through hole, the scraping work, and the vertical pipe work. You can eliminate the position correction and prevent freezing of the water supply branch pipe and hot water supply branch pipe,
The above-described effect is achieved in that a predetermined corridor width can be secured without spending time and money for construction of the frame. Further, in the above-mentioned embodiment, the gas meter, the water meter and each branch pipe are incorporated in the box, but this may be attached later. Further, the vertical pipe of the present invention is not limited to the water supply pipe and the gas vertical pipe of the embodiment, and may be an electric main line pipe or the like. Further, instead of the end holding tool for the separator on the outer surface of the box body of the embodiment, it is possible to directly project the separator on the outer surface of the box body.

As is apparent from the above description, the method of constructing the equipment concentrating unit that also serves as the formwork of the present invention is as follows. While vertically extending the common vertical pipe that the upper end penetrates through the upper plate and projects beyond the slab thickness of the building over substantially the entire height of the box, for the outer surface of the box multiple separators or for multiple separators An equipment holding unit is provided by providing an end holder, and the equipment collecting unit is installed on the indoor side on the floor slab so that the opening of the box is aligned with the corridor edge, and the common vertical pipe is installed from the floor slab. The process of connecting to the common vertical pipe on the lower floor protruding, and connecting both sides of the opening of the box body to the wall formwork installed along the corridor, and the side plate of the box body from the indoor side The above separator is placed in the concave wall formwork installed so as to surround this side plate. And by connecting the upper plate of the box body,
Connecting to the floor slab or beam formwork on the upper floor, concrete between the side plate and the recess wall formwork, above the top plate or between the top plate and the beam formwork and in the wall formwork. Since it has a process of placing the building and integrating the building centralized unit with the installation centralized unit, it is possible to carry out the skeleton work and the vertical pipe work at the same time, so the vertical pipe work can be facilitated and the bottleneck in the construction can be eliminated. In addition, it eliminates the need for rigid pipe work even in narrow places such as the recess wall, and improves work efficiency by eliminating rainwater leaks associated with through holes, sealing work around through holes, scrubbing work, and vertical pipe position correction. At the same time, since the box body is embedded in the recess wall, it is possible to secure a predetermined corridor width without labor and cost for constructing the body.
