Description

[Detailed Description of the Invention] [Field of Industrial Application] When forming a concrete structure for a building, the present invention lays a conduit before pouring the concrete, and inserts a flexible pipe into the conduit after pouring the concrete. Equipment piping method to insert,
Also, it relates to the conduit used in the construction method.

[Prior art]

Conventionally, as shown in FIG.
As shown in Figure B, after pouring concrete 13,
A flexible pipe 14 is attached to each of the conduits 17.
and electric wires 15 were inserted one by one by pushing or pulling.

[Problem that the invention seeks to solve]

However, since only one flexible pipe 14 or electric wire 15 can be inserted into one conduit 17, as the number of required piping and wiring increases, a large number of conduits 17 must be laid before concrete pouring. 17 It required a lot of time and labor to lay the ground, which was one of the causes of high construction costs and a long construction period. In particular, when installing various types of piping and wiring such as gas piping, water piping, heating and cooling piping, power supply wiring, control wiring, etc., each equipment contractor will be responsible for the construction of conduits17.
Each conduit was laid separately, and there were significant drawbacks such as a rise in construction costs and an extension of the construction period due to the construction of conduit 17.

An object of the first invention is to develop a construction method that can lay conduit in a short time and with less labor compared to the number of pipes.

It is an object of the second invention 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]

The characteristic means of the building equipment piping construction method according to the first invention is that the conduit to be laid before concrete pouring is configured to have flexibility, and at least a plurality of pipe insertion holes are formed in the conduit. The method is to lay the conduit at a desired position and in a desired posture, and insert a plurality of flexible pipes into the plurality of insertion holes separately after concrete is poured. The effects are as follows.

[Effect]

In other words, by configuring the conduit to be flexible and by forming multiple pipe insertion holes in one conduit and, if necessary, wiring insertion holes, the conduit can be made flexible. It is now possible to lay the conduit in a desired position and in a desired attitude, and even if there are many pipes and wiring, it is now possible to lay only one or a small number of conduits.

〔Effect of the invention〕

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

[Means to solve the problem]

The characteristic structure of the conduit for building equipment piping according to the second invention is that it is configured to have flexibility, and includes one or more first insertion holes for inserting flexible pipes for heating and cooling, and flexible pipes for fuel gas. One second insertion hole for inserting a pipe, one for inserting a flexible pipe for cold water supply
The third insertion hole of the book, one or more fourth insertion holes for inserting a flexible pipe for hot water supply, and one or more fifth insertion holes for inserting an electric wire are defined. , its effects are as follows.

[Effect]

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, one or more heat medium piping between this machine and the indoor air-conditioning unit, and hot water piping from this machine to the hot water supply section, from the entrance side to the balcony. Often set up.

Therefore, if the conduit is configured to have flexibility and the above-mentioned first to fifth insertion holes are formed in the conduit, the conduit can be positioned at a desired position and in a desired posture. The conduit can be laid along the desired route from the entrance side to the balcony, and by simply laying one conduit from the entrance side to the balcony as described above before concrete pouring. Various flexible pipes and wiring required for gas-fueled air conditioning and hot water supply can be installed using conduits after concrete is poured.

〔Effect of the invention〕

As a result, when conduit is laid before concrete pouring for gas-fueled heating and cooling or hot water supply in apartment complexes, it is now possible to simply lay one conduit, whereas in the past it was necessary to install five or more conduits. It is now only necessary to install the conduit, and the time required for laying conduit and the number of workers can be greatly reduced for the entire housing complex, which generally has a large number of housing units, and it is possible to effectively reduce construction costs and shorten the construction period. It became like that.

〔Example〕

Next, an example will be shown with reference to FIGS. 1 and 2.
As shown in FIG. 1, the conduit 1 is made of flexible, electrically insulating, and water-impermeable synthetic resin, and has flexibility.
, three first insertion holes 2 for heating and cooling piping;
One second insertion hole 3 for fuel gas piping, one third insertion hole 4 for cold water supply piping, one fourth insertion hole 5 for hot water supply piping, and a power source. Two fifth insertion holes 6 for use and control wiring
are formed into sections in parallel with each other and each having a required diameter.

As shown in Figure 2 A and B, before slab concrete is poured into each unit of an apartment complex, the pipes are connected to the veranda 8 from the pipe gathering point (A) on the entrance side near the meter box 7 for city gas, water, and electricity. Glue and connect the conduit 1 shown in Fig. 1 with the tube 9 across the installation location (B) of this unit for cooling/heating and hot water supply, and position it at the desired position and attitude along the desired route. At the same time, it is laid between the reinforcing bars 11.

In addition, as shown in Figure 2 A, the installation location of this machine is
From (B) to the room () and the connection installation point (C) for the indoor air-conditioning unit in (), from the pipe collection point (A) to the hot water supply section D ₁ of the kitchen, bath, and washroom,
Across each of D ₂ and D ₃ , and the piping gathering point (A)
From the room () to the connection fitting installation location (E) for the indoor air-conditioning unit in (), it is constructed to have flexibility, and the necessary types and numbers of insertion holes are defined for each. Formed conduit 12
a, 12b, 12c, 12d, and 12e are positioned at desired positions and in desired postures along the desired path, and the reinforcing bars 1 are placed before placing the slab concrete.
