DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, a facility centralized unit for each house is:
In order to facilitate maintenance and inspection of the equipment piping, gas water heater, on-off valve and meters to be housed inside, a recess is provided in the wall on the corridor side of high-rise apartments etc. to form a chamber, which is installed in this chamber. I was However, if such a chamber is constructed from cast-in-place concrete or PC plate at the time of frame construction, the construction cost is high because the labor for forming the wall recessed formwork and the production and installation of the PC plate become large. There was a disadvantage of becoming. Therefore, as a facility centralized unit for each house that solves such a drawback, a unit as shown in FIG. 7 has been proposed (Japanese Patent Publication No. 61-49582). This equipment centralized unit is located in the area adjacent to a pair of doors.
The corridor side of the cast-in-place concrete or PC plate wall 53 that is provided one by one and separates the interior 51 and the common corridor 52 is covered with a pipe cover 54, and a common water supply penetrating the floor and ceiling slab of the corridor 52 therein. A vertical pipe 55, a pair of sewage vertical pipes 56, a ventilation vertical pipe 57, and a gas vertical pipe 58 are accommodated.
After finishing the floor and ceiling slabs of the wall 53 and the corridor 52, a pair of gas water heaters 59 fitted into the openings provided in the pipe cover 54 with their front faces protruding are supported by fittings (not shown). A pair of water meters 60 and gas meters 61 are installed in the pipe cover 54, and the vertical pipes corresponding to these devices are connected to water, gas, and hot water supply via open / close valves at important points. Each branch pipe 62, 63, 64 connects. The horizontal pipes 65, 66, 67 for water, gas, and hot water branched from the branch pipes 62, 63, 64, and a pair of sewage horizontal pipes 68 are mounted on a board 69 fitted into the opening of the wall 53.
Through each of the rooms 51, and tap water, gas,
Hot water is supplied.

[0003]

However, since the above-described conventional equipment centralized unit is provided in a pipe cover 54 which projects into a corridor 52 and is exposed to outside air and wind, the cold water supply branch pipe 62 and the hot water supply branch are provided. There is a problem that the tube 64 freezes. In addition, the corridor 5 corresponds to the amount that the pipe cover 54 protrudes.
When the waist wall outside the corridor is made linear in the plan view, the width of the corridor naturally widens, and wasteful space is created in places other than the pipe cover part, while conversely, the corridor width decreases. If it is desired to make the height constant, the waist wall of the pipe cover portion must be made convex in a plan view, and there is a problem that it takes time and cost to construct the convex waist wall.

The water supply, sewage, ventilation, and gas vertical pipes 55 to 58 penetrating the floor and ceiling slabs of the corridor 52 are:
Usually, when the above slab is cast-in-place reinforced concrete, place sleeves for through holes in the formwork, then cast slab concrete on the floor and ceiling, and insert these vertical pipes into the through holes created after casting. The slab is inserted through
In the case of a plate, these vertical pipes are arranged by penetrating through holes formed 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 a through hole is often not opened at the specified position, so it is necessary to cut the concrete side and align it on the vertical pipe side. The efficiency is reduced, and rainwater leaks from the through hole to the lower floor unless the vertical pipe is provided and the surrounding area is sealed. In addition, since formwork dismantling after casting concrete is performed after the concrete placement on the 3rd to 4th floors is completed, vertical pipe and plumbing work will be considerably delayed, and various miscellaneous operations will be performed. Immediately before the completion of construction, where the work is concentrated, this plumbing work may delay the completion. On the other hand, in the case of the latter, there is no problem of the positional deviation of the through-hole and the construction delay as in the former, but there is a problem that it takes time to drill at the factory,
There is the same problem of rainwater leakage as the former.

Accordingly, an object of the present invention is to devise the structure of this unit based on the idea that a unit accommodating equipment pipes for each house and a heat source device is also used as a mold for a concave portion of a corridor-side outer wall of a room. In this way, it is possible to secure the required corridor width without the need for labor and cost for construction, prevent freezing of water supply branch pipes and hot water supply branch pipes, eliminate the risk of rainwater leakage and eliminate slab shaving work, and To improve work efficiency, especially for building work and vertical pipe and plumbing work at the same time, eliminating bottlenecks in the work, and also making effective use of the space under the beam, making pipe work for each house possible. It is an object of the present invention to provide a facility centralized unit that can also be used for a formwork.

Therefore, the simultaneous construction of the skeleton and the vertical pipe can eliminate the bottleneck in the construction, eliminate the risk of rainwater leakage due to the slab through hole for the vertical pipe, eliminate the cutting work and correct the position of the vertical pipe, and reduce the box body wall. Since it is buried in the concave portion, a predetermined corridor width can be secured without the labor and cost of construction, and freezing of the water supply branch pipe and the hot water supply branch pipe connected to the gas water heater is also prevented. Thereafter, if necessary, for example, a door is attached to the box body, and, for example, a common pipe, a gas water heater, and branch pipes and meters for connecting the open / close valve to each other are attached to the box body. In addition, it is also possible to attach all the branch pipes and meters to be attached later in the box body in advance.

In the facility centralized unit of the present invention, a step corresponding to the cross-sectional shape of the beam is provided on the upper plate of the box, and a notch of the same shape is provided at the upper end of a pair of opposed side plates. ing. Therefore, in the same manner as described above, the lower end of the common vertical pipe in the box is connected to the upper end of the lower common vertical pipe protruding from the floor slab, and the outer wall form is connected to both sides of the front of the box. Subsequently, after arranging the reinforcing bars of the wall along the inner surfaces of the box and the wall form, a mold for the concave wall on the back of the box and an inner wall form are arranged inside these, and furthermore, The side plate of the body and the formwork for the recessed wall are connected by a separator inserted through the end holder.

A method of placing concrete using the above-structured unit having a combined use of a mold and a facility is as follows.
First, with the opening of the box 1 facing the corridor side (Fig. 4
See below) Install concrete at a predetermined position on the floor slab on which concrete is to be cast, and connect the water supply in the box 1 and the female connection portions 4a, 5a at the lower ends of the gas vertical pipes 4, 5 to the lower floor water supply projecting from the floor slab. , Connected to the male connection parts 4b, 5b at the upper end of the gas vertical pipe,
The left and right outer wall forms 34a, 34a
Connect to Subsequently, the reinforcing bar of the wall is arranged along the inner surfaces of the box 1 and the wall form.
As shown in FIG. 6 and FIG. 6, the back form 32 and the side form 33 for the concave wall on the back of the box body, and the left and right inner wall forms 34b, 34.
b is arranged, and a plurality of end holders 7, 7... provided on the outer surface of the side plate 3 of the box 1 are threaded at both ends of the round steel as shown in FIGS. The separator 30 is horizontally inserted from the inner surface side, the back mold 32 for the concave wall and the side molds 33, 33 facing each other are penetrated, and the nut 37 screwed to the end of the separator is tightened to the inside. And the outer mold are connected at a predetermined distance. Next, the wall forms 34a, 34b
And the upper plate 2 of the box 1 are connected to the formwork 39 of the floor slab on the upper floor, and the step 8 of the upper plate of the box 1 and the formwork 39 of the floor slab are connected to the lower formwork 40 of the beam. Connect to the side forms and place the slab and beam reinforcement in these forms. The connection between the box 1 and each of the wall forms is performed by a well-known method shown in FIGS. 4 to 6, that is, by connecting the other end of the separator 30 inserted through the wall form and the supporter 35 assembled vertically and horizontally on the outer surface thereof. , And is stopped by a nut 37 via a washer 36. If the upper plate 2 is flat and has no stepped portion 8 and the side plate has no notch 9, the upper plate may be connected to the formwork 39 of the upper floor slab (see FIG. 5).

Thus, as shown in FIGS. 4 and 5, the lower formwork 40 of the beam forms the same horizontal plane as the step 8 of the upper plate 2,
The formwork 39 of the upper floor slab forms the same horizontal plane as the top of the upper plate 2, the side formwork 31 of the beam and the vertical portion of the upper plate 2 face each other, and the beam 38 to be cast forms the box 1. And the upper end 4b of the water and gas vertical pipes 4 and 5 penetrating through the upper plate 2 while the height of the box 1 becomes the inside height of the floor where concrete is to be cast. , 5b project beyond the thickness of the floor slab on the upper floor indicated by the broken line in FIGS. 4 and 5, the installation of the formwork is completed. Next, concrete is poured into the form as shown by the cross-sectional symbols in FIGS. 4 to 6, and after the concrete is hardened, the form is removed. Thereafter, the unconnected gas and water meters 15 and 16 in the box 1 are removed from the respective branch pipes 18 and 20;
3, 26; 28 and the gas water heater 6, the door 12 is attached to the front of the box 1, and the construction of the equipment centralized unit is completed. Thus, the concrete construction as the skeleton construction and the construction of the equipment centralized unit including the water supply pipe and the gas vertical pipes 4 and 5 are simultaneously performed, and the steel box 1 containing the equipment pipes and the gas water heater 6 is composed of the skeleton. That is, they are integrated while being embedded in the recess wall.

Therefore, by simultaneous construction of the skeleton and the facility centralized unit, the vertical pipe work does not follow up the skeleton construction as in the prior art, and the completion is not delayed. This eliminates the necessity of shaving concrete and correcting the position of the vertical pipe, greatly facilitating the vertical pipe construction and preventing rainwater from leaking down through the through holes to the lower floors. Further, since the box 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 and the wind in the cold season, so that the branch pipes can be prevented from freezing and project into the corridor 52. Since the part (see FIG. 7) is eliminated and the wall and the lumbar wall become parallel straight lines in the plan view, the corridor can be set to a predetermined width without any labor and cost for construction of the skeleton.

In the above embodiment, the step 8 is provided in the upper plate 2 of the box 1 and the notch 9 is provided in the side plates 3a and 3b, and this portion is used as a part of the beam form. Since the cast concrete beam 38 is supported by the floor slab via the box 1, the strength of the form is increased and the number of supports 35 can be reduced. There is an advantage that the formwork of the floor slab is reinforced and easily assembled, and the space under the beam can be effectively used for installation of the facility centralized unit, thereby saving the building space. Also,
Since the horizontal pipes 27, 21, and 29 for gas and hot water supply penetrate through the side plate 3c at the back of the box 1 and protrude beyond the wall thickness as shown in FIGS. In addition, there is an advantage that after the concrete is cast, the pipes protrude into the room from the wall, thereby facilitating subsequent plumbing work in the room.

The upper plate of the box body of the present invention and the pair of opposing side plates may be flat without step portions or notches, unlike the above embodiment. The branch pipes for gas, hot water and the like may not have the horizontal pipes penetrating the back side plate. Even in these cases,
Structural work and vertical pipe work can be performed at the same time, and the box body is embedded in the recessed wall, facilitating vertical pipe work and eliminating bottlenecks in construction, rainwater leakage due to through holes, shaving work, vertical pipe work. Eliminates position correction, prevents freezing of water supply branch pipes and hot water supply branch pipes,
The above-described effect that a predetermined corridor width can be ensured without spending time and money on the construction of the frame is achieved. Further, in the above embodiment, the gas meter, the water meter, and the respective branch pipes are incorporated in the box, but these can be retrofitted. Further, the vertical pipe of the present invention is not limited to the water pipe and gas vertical pipe of the embodiment, but may be an electric main pipe. Further, instead of the end holder for the separator on the outer surface of the box of the embodiment, it is also possible to project the separator directly on the outer surface of the box.
