Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a building piping design method.
[0002]
[Background]
Conventionally, a unit type building constructed by combining a plurality of box-shaped building units manufactured in advance in a factory at a construction site has been used (see JP-A-7-286367). According to this unit type building, the work at the construction site is greatly reduced, so that the merit that the construction work can be completed in a short period of time can be obtained.
In such unit-type buildings, water pipes, hot water pipes composed of resin pipes using cross-linked polyethylene for draining water and hot water in bathrooms, toilets, kitchens, etc., Drainage pipes are installed.
[0003]
When installing these water supply pipes, hot water supply pipes, drain pipes, etc., for example, pipes are built into each building unit, and the building units are assembled adjacent to each other at the construction site, and then the pipes between the building units are connected to each other. It is joined to.
Here, the pipes and the like are directly connected by a plumber who is instructed by the dealer who has taken over the responsibility for supervision of the unit type building from the building maker who supervises the construction of the unit type building.
In other words, the plumbing company determines the dimensions of the pipes to be piped based on the design information related to the piping in the building, cuts the pipes appropriately according to the dimensions, performs installation work, and at the construction site, The pipe connection member necessary for connecting the pipes is selected, and the operation of connecting the pipes is performed.
[0004]
[Problems to be solved by the invention]
In such a building plumbing method, pipes are cut and connected while referring to design information related to piping in the building every time a plumbing company pipes a building unit or joins a pipe at a construction site. Since work is performed, there is a problem that work efficiency is poor.
[0005]
On the other hand, it is conceivable that the plumbing company cuts the pipes to the predetermined dimensions in advance based on the design information related to the piping in the building, and arranges the necessary parts and transports them to the construction site, but the cutting dimensions were incorrect. In some cases, another pipe must be cut in place on the spot.
Therefore, it has been proposed to improve the working efficiency by causing some errors in the cut dimensions to be expanded and contracted using a flexible pipe (see Japanese Patent No. 2606808).
[0006]
However, the creation of design information related to piping in a building, such as the piping length required for the piping route, remains an existing method, and it takes time and effort, so it is difficult to improve work efficiency. There is.
[0007]
The objective of this invention is providing the piping design method of the building which can improve work efficiency.
[0008]

The toilet bowls 31 and 36, the washing machine 32, the wash basin 33, the bathroom 34, and the kitchen 35 may be pipe members drawn into the building from the water heater 37 and / or the water heater 38 installed outdoors. A flexible pipe 41 is connected. That is, a piping path 40 in which a plurality of pipes 41 are piped is formed between the lower floor building unit 10, the upper floor building unit 20, and the lower floor building unit 10.
[0014]
The piping path 40 in the building 1 can be broadly divided into two parts: a pipe part that is straightly piped and a pipe part that is connected to the pipe that is piped in a straight line and is branched.
That is, the plurality of pipes 41 pass through the two lower-floor building units 10B and 10C and go to the bathroom 34, and the two long pipes 41A branch from the long pipe 41A to each kitchen 35 and the washing machine 32.

[0016]
The piping construction procedure of such a piping path 40 will be described below.
First, by using a piping design system 50 (FIG. 3) that realizes the piping design method of the present invention, the required piping length of the piping path 40, which is design information related to piping in the unit type building 1, is obtained.
The piping design system 50 includes a computer 51, a keyboard 52 and a mouse 53 that are input devices for inputting various information to the computer 51, and a display 54 that is a display device that displays information processed by the computer 51. Configured.
[0017]
As shown in FIG. 4, the computer 51 includes a control unit 51A and a data storage unit 51B.
The control unit 51A includes a standard value setting unit 61 that sets a necessary pipe length required for the configuration of the pipe path as a standard value, and the pipe path 40 of the unit type building 1 based on the design information of the unit type building 1. There are programmed piping route setting means 62 to be set and piping length calculation means 63 for calculating the required piping length of the piping route 40 by referring to the standard value and corresponding to the form of the piping route 40. Are controlled on an OS whose operation is controlled by a CPU (not shown) constituting the control means.
[0018]
In the data storage unit 51B, a standard value setting table set with reference to the natural length of the pipe 41 and set with standard values corresponding to the above-described form is stored for each building hierarchy and each building type. Yes.
Here, as a form, it is piping to the plane routing part, the rising part, the bending part, the branch part, and the wash basin 33, the kitchen 35, the toilet bowls 31, 36, the laundry 32, and the bathroom 34 that constitute the piping path inside the building. Route and the like.
[0019]
In this piping design system 50, as shown in FIG. 5, first, design information of the unit type building 1 created by the designer who has performed the basic design of the unit type building 1 is taken in (S1). Then, the control means 51A displays a plan view of the unit type building 1 on the display 54 as shown in FIG. 6 based on the fetched design information (S2). Here, the fetched design information includes CAD data, a plan view program, and the like.
[0020]
When the plan view is displayed, the standard value setting means 61, as shown in FIG. 7, shows the necessary piping required for the configuration of the piping path 40 of the unit type building 1 from the plan view of the unit type building 1. A standard value setting table 61A in which the length is set as a standard value is selected from those stored in the data storage unit 51B and displayed on the display 54 (S3). Next, when the designer presses an execution button (not shown), the piping route setting unit 62 automatically sets the piping route 40 of the unit type building 1 as shown in FIG. 6 (S4).
[0021]
When the pipe path 40 is set, the pipe length calculation unit 63 associates the form of the standard value setting table 61A with the pipe path 40 and calculates the necessary pipe length of the pipe path 40 with reference to the standard value ( S5).
[0022]
Specifically, first, the pipe length calculation means 63 calculates the length dimensions of the pipes 41A to 41E based on the dimensions of the building units 10 and 20, and calculates the sum of them.
Here, the plane vertical dimension A and plane horizontal dimension B of each building unit 10 and 20 are 4M (910 * 4 = 3640 mm) and 2.5M (910 * 2.5 = 2275 mm), respectively. Further, half of the plane lateral dimension B is the plane lateral dimension C, and similarly, ¼ of the plane lateral dimension B is the plane lateral dimension D.
Accordingly, the length of the long pipe 41A is calculated to be 8080 (7280 + 800) mm because the two lower-floor building units 10B and 10C penetrate in the vertical direction and the end portion is raised and connected to the bathroom 34. .
[0023]
Similarly, the length of the first branch pipe 41B is substantially the same as the horizontal plane dimension C, and the end portions of the first branch pipe 41B are raised to the kitchen 35, the washing machine 32, and the washstand 33, respectively. .5 (1137.5 + 700) mm, 3337.5 (1137.5 + 2100) mm, and 1837.5 (1137.5 + 700) mm.
The length of the second branch pipe 41 </ b> C is the sum of 3/4 of the horizontal plane dimension B and approximately half of the vertical plane dimension A, and the end portion of the second branch pipe 41 </ b> C rises to the toilet 31, so that 4226.25 ( 3526.25 + 700) mm.
The length dimension of the rising pipe 41D is calculated as 3600 mm from the standard value setting table 61A.
The length of the third branch pipe 41E is the sum of 3/4 of the horizontal plane dimension B and about the vertical plane dimension A, and the end portion of the third branch pipe 41E rises up to the toilet 36, so that the length is 6046.25 (5346. 25 + 700) mm.
[0024]
Then, the sum of the lengths of the long pipe 41A, the first to third branch pipes 41B, 41C, 41E, and the rising pipe 41D is calculated as 28965 mm and displayed on the display 54. Thus, the designer can obtain the necessary pipe length in the pipe path 40.
In this way, design information regarding piping in the unit type building 1 is obtained.
In addition, this piping design system 50 can be used not only for piping design at the time of new construction of the unit type building 1 but also for piping design at the time of renovation of an existing unit type building, for example.
[0025]
Next, in the factory, various parts such as pipes necessary for the pipe are manufactured based on the pipe design information obtained by the pipe design system 50 described above.
Specifically, red and blue pipes manufactured for the length of the calculated required pipe length are prepared, and the long pipes 41A, the first to third branch pipes 41B, 41C, and 41E that are used are started up. Cut to the length of the pipe 41D.
Each long pipe 41A, first to third branch pipes 41B, 41C, 41E, a pipe support member 43 that supports the rising pipe 41D in a predetermined position, and each long pipe 41A, first to third branches The pipe connection members 42 that connect the pipes 41B, 41C, 41E and the rising pipes 41D to each other are manufactured as much as necessary.
[0026]
And the piping package 70 which made the set required for piping of the unit type building 1 is made, and it ships from a factory.
Specifically, as shown in FIG. 8B, the pipe connection member 42, the pipe support member 43, and the like manufactured for the piping of the unit type building 1 are packed into the box 71 as shown in FIG. Similarly, the various pipes 41 </ b> A to 41 </ b> E necessary for the piping of the unit type building 1 are wound in a spiral shape and stored in the pipe package 72 as shown in FIG. 8A.
And the piping package 70 is formed by setting the box 71 and the pipe package 72 as a set. In the pipe package 72, two types of pipes 41A to 41E of red and blue corresponding to the piping system after assembling the unit building 1 are prepared as necessary.
The piping package 70 made in this way is shipped from the factory and transported to the construction site.
It should be noted that the process up to this point, in other words, the series of processes from the creation of design information regarding piping in the unit type building 1 to the shipment of the piping package 70 is performed by a building maker who directs the construction of the unit type building 1. It has become.
[0027]
Next, at the construction site, a plumbing company that performs piping construction opens the pipe package 70 that has been transported, installs various pipes 41A to 41E, and connects the pipes 41A to 41E with the pipe connecting member 42. Then, a component installation process to be supported by the pipe support member 43 is performed.
In this way, the piping construction of the piping path 40 is performed.
[0028]
According to this embodiment, the following effects can be obtained.
That is, the pipe length of the pipe path 40 is obtained by making the form correspond to the pipe path 40 set based on the design information of the unit type building 1 and making the standard value set according to the form correspond. As a result, the pipe length can be calculated more easily than in the prior art, thereby improving work efficiency.
[0029]
Further, since the flexible pipe 41 is used, it can be easily bent, bent and stretched, can flexibly cope with dimensional errors and the like, and can be easily piped. Also from this point, work efficiency can be improved.
[0030]
Furthermore, since the standard value is set based on the natural length of the pipe 41, it is possible to easily cope with dimensional errors and the like by expanding and contracting the pipe 41, and the applicable range of the pipe 41 can be expanded. it can.
In addition, since the standard value is set for each level of building and for each type of building, it is possible to flexibly deal with various buildings. From this point as well, the applicable range of the pipe 41 can be expanded.
[0031]
In addition, this invention is not limited to the said embodiment, Other structures etc. which can achieve the objective of this invention are included, The deformation | transformation etc. which are shown below are also contained in this invention.
For example, in the above-described embodiment, the standard value is set for each building hierarchy and for each building type. However, the present invention is not limited to this, and for example, only a unit type building may be set.
[0032]
Moreover, in the said embodiment, although the standard value was set on the basis of the natural length of the pipe 41, it is not restricted to this, For example, it may be based on the extended state, or it may be based on the contracted state. Well, what state should be used as a reference may be determined as appropriate during implementation.
[0033]
Furthermore, in the said embodiment, although the pipe was flexible, it is not restricted to this, For example, the thing which is hard to bend made of steel or iron may be used.
[0034]
Further, the form is not limited to the items of the above-described embodiment, and may be determined as appropriate upon implementation.
[0035]
In addition, the building is not limited to the unit building 1 in which a plurality of building units formed in a box shape are combined, but a panel-type prefab house in which a plurality of wall panels and floor panels formed in a plate shape are combined, a pillar, It may be a general building consisting of conventional construction methods where beams are joined at a construction site.
[0036]
Furthermore, in the above embodiment, the required piping length is automatically calculated by the piping design system, but not limited to this, for example, on a desk, a designer writes a piping path on a paper drawing and measures its length, The necessary pipe length may be calculated by hand while referring to a standard value set in advance.
