Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention, when forming a concrete structure for a building, lays a conduit before placing the concrete, and installs a flexible pipe inside the conduit after placing the concrete. Regarding the equipment piping method to be inserted and the conduit used in that method.

[Prior art]

Conventionally, as shown in Fig. 4 (a), a commercially available electrical wiring conduit (l?) was laid, and the same number of conduits (17) as the required number of piping and wiring were placed. B)
As shown in K, after concrete I is poured; conduit +
1? ) for each of 7 Lexi pull wires 0 x
The books were inserted one by one by pushing and pulling.

[Problem that the invention seeks to solve]

However, because it is not possible to insert 7 conduits (7 flexible pipes 04 in lη) or electric wires (lfi), the more piping and wiring required, the more conduits θη must be laid before concrete is poured. 07) Laying the concrete required a lot of time and labor, contributing to higher construction costs and longer construction periods.

Especially 1 gas piping, water piping, heating and cooling piping, power wiring,
When installing various types of piping and wiring such as control wiring, each equipment contractor has to lay each conduit17) separately, which has the disadvantage of significantly increasing construction costs and extending the construction period due to the construction of conduits θη. there were.

The first object of the present invention is to develop a construction method that enables conduit laying in a short period of time and with less labor compared to the number of pipes.

An object of the second invention is to provide a conduit for equipment piping that is convenient for piping for gas-fueled heating and cooling or hot water supply in an apartment complex.

[Means to solve the problem]

Characteristic means of the building equipment piping method according to the first invention are as follows:
At least a plurality of pipe insertion holes are formed in the conduit to be laid before concrete is poured, and a plurality of flexible pipes are inserted into each of these penetration holes after concrete is poured. The effects are as follows.

[For production]

In other words, by forming multiple pipe insertion holes and, if necessary, wiring insertion holes in a single conduit, you can install at most 7 pipes and wires, or a small number of conduits. Now you can get away with it.

〔Effect of the invention〕

As a result, conduit installation prior to concrete pouring can be done in a short period of time and with fewer workers, despite the large number and types of piping and wiring, reducing construction costs and construction periods. became.

[Means to solve the problem]

7 or more first insertion holes for inserting flexible pipes for fuel gas, 7 #8 holes for inserting flexible pipes for cold water supply, and 7 #8 holes for inserting flexible pipes for cold water supply. Seven or more fourth through-holes for inserting flexible pipes and seven or more fifth through-holes for inserting electric wires are defined, and the effects thereof are as follows.

[For production]

In other words, in an apartment complex, the fuel gas and water main pipes and switchboards are installed at the entrance, and the main unit for heating, cooling, and hot water is installed on the balcony, and the main pipes are used to supply fuel gas and cold water to the main unit. Supply piping, electric wires from the switchboard to this machine, two or more heat medium piping between this machine and the indoor air-conditioning unit, row K
.

Hot water piping from the machine to the hot water supply section is often installed across the entrance side and the balcony.

・Therefore, if the first to fifth insertion holes mentioned above are formed in the conduit, you can easily install seven conduits from the entrance side to the balcony before pouring concrete, and you can use gas-fueled air conditioning or hot water supply. Various flexible pipes and wiring required for this can be installed using conduits after concrete is poured.

〔Effect of the invention〕

As a result, when conduit is laid before concrete is poured for gas-fueled heating, cooling, and hot water in apartment buildings,
Whereas in the past it was necessary to install five or more conduits, it is now possible to install just one conduit per unit, and generally speaking, it is necessary to install conduits for an entire apartment complex with a considerable number of housing units. The construction period and number of workers can be greatly reduced, making it possible to effectively reduce construction costs and construction time.

〔Example〕

Next, an example will be shown with reference to FIGS. 1 and 2.

As shown in Figure 1, a conduit (1) made of flexible, electrically insulating, and water-impermeable synthetic resin has three first insertion holes (2) for heating and cooling pipes, and three first insertion holes (2) for fuel gas. Seven second insertion holes (3) for piping, seven eighth insertion holes (4) for cold water supply piping, seven fourth insertion holes (5) for hot water supply piping, and , one fifth insertion hole (6) for the power source and control wirings is defined in parallel to each other and has the required diameter.

As shown in Figures 2 (a) and (b), before slab concrete is poured for each apartment complex, one pipe convergence point on the entrance side near the meter box (7) for city gas, water, and electricity is installed. From the balcony (8) where the cooling/heating and hot water supply unit is installed (B)
) are glued and connected with tubes (9) and laid between reinforcing bars (tl).

In addition, as shown in Figure 2 (A) K, one machine is installed at the location (B).
) to the room (engineering) and the connection fitting installation point (C) for the indoor unit for air conditioning and heating, and from the piping collection point (4) to the hot water supply section (DI) of the kitchen, bath, and washroom.

(DI)l (Its) From the piping gathering point to the room (to) and the connection fitting installation point for the indoor air-conditioning unit (E) K, the necessary types and number of Conduit with partitioned insertion holes) (12

Next, after pouring slab concrete θ and solidifying concrete 01, as shown in Fig. 2 (c), the first to fourth insertion holes (21, (51
, 71)', other conduit)' (12 m) or tge), insert flexible pipes of appropriate diameters by pushing them in or pulling them through the wires. Connect both ends of the conduit (1
), (IgM) or Ige) by an appropriate length from both ends.

Similarly, insert the power supply and control wires +15 into the fifth insertion holes (6) of the conduit (fl) separately.

After that, necessary connection work and equipment installation work for the plumbing system and wiring system, interior finishing work for the house, etc. are carried out in an appropriate order.

Furthermore, it is convenient to arrange multiple pieces of fil in parallel.

In the first invention, the material, structure, dimensions, etc. of the flexible pipe (14) can be appropriately selected depending on its use.

In forming the conduit (1) according to the second invention, the following various modifications are possible.

(a) As shown in Figure 8 (b), the first to fifth inserts
The through holes (2) to 6) are formed in the same manner as shown in Fig. 1, and the parts other than the diurnal wall (11) through which they are inserted and the supporting parts (1b) therefor are hollow, thereby reducing weight and saving materials. We aim to

(B) As shown in Figure 8 (B), there are many insertion holes (,)
