Description

[Detailed explanation of the idea]

[Purpose of invention]

0001

[Industrial application field]

The present invention is a prefabricated box for storing electrical equipment, etc. that constitutes an uninterruptible power supply, for example. It is related to.

0002

[Conventional technology]

Figure 6 is a perspective view of a box that houses electrical equipment, and Figure 7 is an exploded perspective view of the box. 1 is the door, 2 is the side cover, 3 is the rear door, 4 is the side plate that makes up the box, 5 is a ceiling plate, 6 is a bottom plate, and the box body is constructed by joining side plates 4 to a ceiling plate 5 and a bottom plate 6. It will be done. Furthermore, Fig. 8 shows a structure in which the support column 7 for storing electrical equipment is connected after the box is constructed. FIG.

0003 FIG. 9 shows a conventional method of joining the bottom plate 6 and side plate 4 of FIG. Connect the side plate 4 and bottom plate 6 using rivets 10, and connect the ceiling plate 5 in the same way as the bottom plate 6. It is connected to the side plate 4 by. Note that FIG. 10 is a perspective view of the support column 7.

0004 The box body constructed in this way is a thin plate (1.6 mm to 3.2 mm thick), so it can be used as a transformer. , there is a problem in terms of strength when storing heavy items such as reactors, so the angle weld structure It was impossible to use it unless a box was used or appropriate reinforcement was provided with reinforcing materials. . In this way, in all cases with conventional methods, there is no concern about poor work system or reinforcement materials. This led to higher costs.

[0005]

[Problem that the idea aims to solve]

The present invention improves workability and allows storage of heavy objects, and is low cost. Frameless assembly made of thin steel plate with excellent strength and easy workability. The purpose is to provide a box body. [Structure of the idea]

[0006]

[Means to solve the problem]

In order to achieve the above object, the present invention is formed by combining a ceiling plate, a bottom plate and a side plate. In the frameless type prefabricated box made of thin steel plates, the ceiling plate and bottom plate are U-shaped, and the cross section of the side surface at the joint end with the side plate is formed into an upper and lower L-shape + a U-shape. Furthermore, a pair of support columns having a U-shape on the left and right and top and bottom are attached to the ceiling plate and the bottom plate. It is characterized by a structure that is tightened and fixed with a bed and bolts.

[0007]

[Effect]

In this invention, the cross sections of the ceiling plate, bottom plate, and side plate, which are the components of the box body to be assembled, are are formed into a U-shape and L-shape + U-shape, and the ceiling panels are made of U-shaped pillars on the left and right and up and down. and the bottom plate and each adjacent joint surface are fixed on two or one side with rivets and bolts. Due to the fixed structure, the strength of the box can be increased, and in order to further increase the strength, You can also increase the number of bolts.

[0008]

【Example】

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

[0009] FIG. 1 is a sectional view of the joint end of the bottom plate 16, side plate 14, and support column 17 of the box body of the present invention. The bottom plate 16 is connected to the side plate 14 by rivets 10, and the support column 17 is connected to the bottom plate 16 and It is connected to the side plate 14 by bolts 8 and nuts 9. Also, ceiling plate 1 on the top of the box 5 is also connected in a similar manner.

0010 Furthermore, in order to increase the strength, the bottom plate 16, ceiling plate 15, side plates 14, and pillars 17 are Each is formed in a U-shape. Also, the ceiling plate 15, the bottom plate 16, the side plates 14, and the pillars 17 It has a structure in which two or one surface of each adjacent joint surface is fixed. FIG. 3 shows a perspective view of the strut 17.

[0011] FIG. 2 is a configuration diagram showing another embodiment of the present invention, in which the bottom plate 26 is formed into an L-shape at the joint end. , the bottom plate 26 is connected to the side plate 24 by rivets 10, and the support column 27 is It is connected to the bottom plate 26 by bolts 8 and nuts 9. Ceiling board 25 at the top of the box connected in a similar way. 4 and 5 are perspective views of the struts 27 and 37. support Pillars 17, 27, and 37 are used depending on the shape and weight of the electrical equipment, and are also used for multiple It is possible to further increase the strength by using several.

0012

[Effect of the idea]

As explained above, according to the present invention, a thin steel plate (thickness 1.6 mm to 3.2 mm) is used. However, the ceiling plate, bottom plate, side plate, support column, and adjacent joint surfaces are fixed on two or one side. The strength can be increased by making each part into a U-shape or L-shape + U-shape. Therefore, it is possible to provide an assembly type box body that is easy to manufacture at low cost.
