Description

[Detailed Description of the Invention] This invention relates to a prefabricated package type outdoor power distribution board having an inspection passage inside, and particularly to its roof structure.

Generally, this type of outdoor switchboard is large in size, and conventionally, roof truss beams have been manufactured to fit the size of the outdoor switchboard and assembled using bolts, etc., just like regular steel housings.

For this reason, the configuration of the roof truss differs depending on the size of the outdoor switchboard, and sufficient standardization has not been possible.

Further, when assembling the roof truss, it was difficult to obtain a right angle with the side wall components and the roof component.

This idea was made in order to eliminate the drawbacks of the conventional ones as mentioned above, and by sequentially joining roof trusses welded to a rectangular frame body equal to the width of the roof shingles, the desired size can be achieved. The purpose is to provide an outdoor switchboard that can be configured.

An embodiment of this invention will be described below with reference to the drawings.

Figures 1 to 3 each show an embodiment of this invention. In the figures, 1 is an assembly type package type outdoor power distribution board, which consists of a base component 2, a side wall component 3, and a roof component 4. Become.

5 is a cross beam with a U-shaped cross section, 6 is a side beam with a C-shaped cross section, and these cross beams 5 and side beams L6
The roof truss 7 is constructed by welding each pair to form a rectangular frame.

At this time, the openings of the pair of cross beams 5 are arranged facing inward so as to face each other, and the openings of the pair of side beams 6 are arranged so as to face outward, facilitating assembly, welding, etc. I have to.

Further, the side beam 6 is made of a member whose vertical length is larger than the vertical length of the cross beam 5.

8 is a ceiling plate, and this ceiling plate 8 is inserted into the channel portion of the pair of cross beams 5 of the roof truss 7, placed on the flange portion 5A at the bottom of the cross beam 5, and held by the entire surface of the flange portion 5A. .

Therefore, the ceiling plate 8 can be made of a thin iron plate, and there is no need to provide reinforcing ribs for holding the ceiling plate 8.

Reference numeral 9 denotes a support member mounted on the upper part of adjacent cross beams 5, and the cross beams 5 are connected by bolt members or the like.

Reference numeral 10 denotes a pair of roof plates forming a double-sided roof that slopes outward, and this roof plate 10 is connected to other adjacent roof plates 10.
A rising portion 10A is provided over the entire length on each of the three sides facing the roof, and a hanging portion 10 that completely covers the side beam 6 is provided on the side facing the outside of the roof.
B is provided.

The rising portion 10A is bolted to the vertical leg portion of the support member 9 at the top, and the hanging portion 10B is bolted to the upper flange portion 6A and lower flange portion 6B of the side beam 6.

Reference numeral 11 indicates an adjacent joint cover that covers the joints of adjacent roof panels 10; 12 indicates a top joint cover that is divided into each roof panel 10 and covers the tops of a pair of roof panels 10; and 13 indicates each joint cover 11. A connecting cover covering the joint of .12 is bolted to the upper surface of the support member 9.

14 is an end cover that covers the roof end of the outdoor switchboard, and 15 is an end cover that covers the connecting cover 13 at the roof end.

By the way, to explain the relationship between the roof truss 7 and the roof component 4, the length of the roof truss 7 on the cross beam 5 side is equal to the width dimension of the outdoor switchboard 1, and the length on the side beam 6 side is equal to the width dimension of the outdoor switchboard 1. The width is equal to the width of the roof board 10,
Moreover, the joints of each roof truss 7 and the joints of the roof panels 10 are matched with each other.

For this reason, the longitudinal size of the outdoor switchboard 1 is determined by arranging a predetermined number of roof trusses 7 and roof panels 10, each including a ceiling panel 8 having the same structure, side by side, and tightening the adjacent side abutting portions with bolts. In addition to connecting, the joint cover 11 and the connection cover 1
3 at the joint of the roof plate 10, the length of the roof lath 7 on the side beam 5 side can be made into a desired size as a unit length.

The support member 9 is configured to connect the roof trusses 7 to each other, to connect the roof panels 10 to each other, to connect the roof panels 10 to the roof truss 7, and to serve as a fixing member for the connection cover 13. This makes it possible to reduce the number of parts and the number of fixing points for members, as well as the number of assembly steps.

In FIG. 3, reference numeral 16 denotes an outer wall panel constituting the side wall of the outdoor switchboard 1, and the upper end flange portion 16A and the lower flange portion 6B of the side beam 6 are connected by bolts.

17 is an inner wall panel arranged inside this outer wall panel 16, and 18 is an electric device with a narrow depth, such as a free-standing distribution board, and the supporting metal fittings 1 are used to prevent it from shaking or falling during transportation.
It is fixed to the vertical surface of the side beam 6 via 9.

A metal duct 20 houses electric wires 21 to be wired between lighting circuits and electrical equipment, and is attached to the vertical surface of the side beam 6.

The reason why the side beam 6 is provided with the support fittings 19 and the metal duct 20 in this way is because the side beam 6 is made of a thicker iron plate than the inner wall panel 17, and also because the side beams 1 and 6 are This can be done because the length is larger than the vertical length of the cross beam 6, and a portion thereof is used as a part of the inner wall.

Note that the space formed between the outer wall panel 16 and the inner wall panel 17, the side beam 6 and the roof plate hanging portion 10B
In the space formed between the roof panel 10 and the ceiling panel 8, and the space formed between the roof panel 10 and the ceiling panel 8, a heat insulating material such as glass wool can be stored as necessary to increase the heat insulation effect. .

As described above, in this invention, the roof truss is constructed as a frame with a unit length corresponding to the roof plate, so the desired number of identical roof trusses can be connected in response to changes in the length of the outdoor switchboard in the longitudinal direction. This makes it extremely easy to respond.

Furthermore, since the roof truss consisting of cross beams and side beams is constructed in advance into a highly accurate frame on the ground, if the side wall components and roof components are assembled based on this roof truss, the squareness of each can be adjusted. This has the effect of facilitating highly accurate assembly.
