A plug 17 which is fitted and connected to the connector 15 is attached to the end of the unit 15, and a unit cable 19 is provided so as to be connectable to the connector 15.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a unit type trunk line suitable for use in a building having a fireproof section.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 4, in the main line construction of a building having a fireproof compartment, a sleeve is provided in the slab 1 inside the electric shaft, a rack is laid in the slab 1 and the cable 3 is passed through the slab 1 Partition processing 5 is being performed. At that time, the size of the trunk line was determined in advance in the case of a tenant building.

[0003]

[Problems to be solved by the device]

 In recent years, as office automation has become more popular, many office automation equipments are being used even in general offices, and depending on the tenant, these equipments may be used at the rate of one person per person. In such a situation, it is inevitable that the capacity of the main line that is assumed in advance will be exceeded and that a new tenant will need to move in that requires more than the existing capacity. However, the conventional trunk line has a drawback that when a new trunk line is added, a lot of work such as new sleeve installation and reprocessing of the fire protection section is required, resulting in a large construction cost. The present invention has been made in view of the above situation, and it provides a unit type trunk line that does not require a fireproof section treatment during the construction of the trunk line and can easily connect the extension trunk line. The purpose is to improve the sex.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the unit type trunk line according to the present invention comprises a concrete panel in which a connector which is driven as a unit with a slab and exposes a connection port on the front and back sides of the slab is incorporated, and a connector. It is characterized in that the plug to be mated and connected is composed of a unit cable attached to the end.

[0005]

[Action]

 A concrete panel with a built-in connector is driven into the slab so that the front and back of the slab can be electrically conducted without leaving the sleeve, and the main line can be laid through the slab simply by connecting the unit cable to the connector. Becomes

[0006]

【Example】

 Hereinafter, a preferred embodiment of a unit type trunk line according to the present invention will be described in detail with reference to the drawings. 1 is a side view of the unit type main line of the present invention, and FIG. 2 is a plan view of the unit type main line of the present invention. A small piece-shaped concrete panel 11 formed with a thickness t equivalent to the slab thickness of a building is provided with a reinforcing bar 13 in a direction orthogonal to the thickness direction, so that the concrete panel 11 is driven into the EPS together with the slab. It has become. Therefore, the concrete panel 11 driven into the slab is integrated with the slab, and the front and back surfaces are the same as the slab. A plurality of connectors 15 are incorporated in the concrete panel 11 in the thickness direction, and the connector 15 has connection ports exposed on the front and back sides of the concrete panel 11. In other words, when the concrete panel 11 is driven into the slab, the front and back surfaces of the slab can be electrically connected to each other through the connector 15 without leaving a sleeve, and the fire-proof compartment treatment is unnecessary.

On the other hand, the connector 15 of the concrete panel 11 can be connected to a unit cable 19 having a plug 17 fitted to the connector 15 at an end thereof. The unit cable 19 includes a straight type (straight type unit cable 19a) and a T-branch type (T-branch type unit cable 19b), and each size of different length is prepared. All the plugs 17 of each unit cable 19 are common, and can be fitted with an arbitrary connector 15. Therefore, by using the unit cable 19, the connectors 15 on each floor can be freely connected to each other, or the connector 15 and the distribution board can be freely connected. A unit type trunk line 21 is constituted by the concrete panel 11 and the unit cable 19.

An example of construction of a trunk line using the unit type trunk line 21 configured as described above will be described with reference to FIG. FIG. 3 is an explanatory diagram of an example of main line construction using a unit type main line. The concrete panel 11 driven into the EPS of each floor slab is in a state where the connector 15 faces and the unit cable 19 can be connected. The unit cable 19 is connected and constructed when each tenant is determined and the required electric capacity is determined. In this case, for the tenant with a large required electric capacity, use the linear unit cable 19a as a single trunk line, and for the tenant with a small required electric capacity, combine the T-branch unit cable 19b and the linear unit cable 19a. Branch for 2-3 floors and connect. Also, for example, if an additional distribution board 23 is required on the second floor due to tenant change, etc., connect the connector 15 on the second floor and the connector 15 to the electric room with three unit cables 19. Only then, the main line connection for the extension distribution board 23 is completed.

[0009]

[Effect of device]

 As described in detail above, according to the unit type main line of the present invention, the main line work is completed only by connecting the connector with the unit cable, and the penetration processing of the fire prevention section is not required. It is possible to remarkably improve the serviceability, and it is possible to deal with it very easily even when adding a trunk line.
