The side plate 5 is brought into contact with the opening 3 of the device through the packing 4 and is watertightly fixed with the fixing bolt 7 through the seal washer 6, and as necessary for inspection of the internal equipment. The side plate 5 was removed.

In the case of fixing the side plate 5 as described above, the side plate 5
Since the packing 4 is pressed by, the mutual interval of the bolts 7 is narrowed so that sufficient waterproofness can be obtained.

(Problems to be Solved by the Invention) However, if a large number of bolts 7 are provided at narrow intervals, there is a problem that it takes a lot of time and labor to attach and detach the side plate 5.

The purpose of the present invention is to obtain the required waterproofness and to install and
An object is to provide a box body that can be easily removed.

(Means for Solving the Problems) The structure of the present invention for achieving the above object will be described with reference to FIGS. 1 to 6 corresponding to the embodiments. In a box body in which a side plate 5 is detachably and waterproofly attached to the side opening 3, a frame member 8A on the upper side, a frame member 8B on the lower side, and a left side member are provided on the periphery of the opening 3. A frame member 8C and a right frame member 8D are provided, and outward folding members 9A and 9B are provided on the inner walls of the left and right frame members 8C and 8D facing the opening 3.
Are watertightly projected along the up-down direction, and the side plate 5 is provided with inward turn-back portions 5C and 5D on the left and right edges thereof along the up-down direction. Is provided with a plate surface retreating portion 5A for insertion, and the side plate 5 inserts the plate surface retreating portion 5A for insertion into the inside of the upper frame member 8A, and the left and right inward folding portions 5 are formed.
C and 5D are inserted into the respective folded recesses 9A1 and 9B1 of the outward facing plate return members 9A and 9B, and the lower end edges thereof are exposed to the outer surface of the lower frame member 8B and are fixed so that they can be removed. Is characterized by.

(Operation) When the side plate 5 is attached in this manner, water does not enter the box body 1 from each part of the peripheral edge of the side plate 5. Further, the number of fixing bolts 7 used can be reduced, which facilitates mounting and removal.

(Embodiment) An embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 6. As shown, in the box body of this embodiment,
An upper frame member 8A, a lower frame member 8B, a left frame member 8C, and a right frame member 8D are provided on the periphery of the side opening 3.
Is provided. Outward folding members 9A and 9B made of angle steel are watertightly projected in the vertical direction on the inner wall surfaces of the left and right frame members 8C and 8D facing the openings 3, respectively. The folding end faces of the outward folding members 9A and 9B are provided so as to recede from the surfaces of the left and right frame members 8C and 8D, respectively.
The lower ends of A and 9B are watertight on the inclined surface 10 and the lower frame member 8B.
The drain portions 11 are provided at the lower ends of the outward folding members 9A and 9B. Notches 12 are provided at the upper ends of the outward folding members 9A and 9B to facilitate insertion of the upper edge of the side plate 5.

An insertion plate surface retreat portion 5A is formed by being bent at the upper edge portion of the side surface plate 5, a lower edge portion is formed as a straight portion 5B that is flush with the upper portion thereof, and the left and right edge portions face inward. Folded portions 5C and 5D are formed. Handles 13 are provided on both sides of the front surface of the side plate 5, and fixing bolt through holes 14 are provided in the straight portion 5B. The lower frame member 8B is provided with fixing screw holes 15 corresponding to the fixing bolt through holes 14 of the side plate 5. A stopper member 16 is fixed to the inner surface of the side plate 5 so as to ride on the upper surface of the lower frame member 8B and support the side plate 5 when the side plate 5 is fitted into the opening 3 at a predetermined position. ing.

A packing 17 having a U-shaped cross section is attached to each of the outward folding members 9A and 9B along the longitudinal direction.

In such a box body, the opening 3 on the side surface of the box body 1
The side plate 5 is inserted into the upper frame member 8A at the upper end thereof, and the inward folded portions 5C5D at the left and right edges of the side plate 5 are inserted into the upper frame member 8A, and the left and right outward folded members 9A and 9B are formed. Fit into the folded recesses 9A1 and 9B1 of
The straight portion 5B at the lower edge is exposed to the outer surface of the lower frame member 8B, and the stopper member 16 is mounted on the upper surface of the lower frame member 8B. In this state, the fixing bolt 7 is inserted through the seal washer 6 into the fixing bolt through hole 1 of the side plate 5.
The inner surface of the side plate 5 is pressed against the folded-back ends of the outwardly folded-back members 9A and 9B via the packing 17 by being threaded into the fixing screw holes 15 of the lower frame member 8B.

(Effects of the Invention) As described above, according to the present invention, outward folding members are watertightly provided on the left and right inner walls of the opening of the box body, and the side plate is provided with the insertion plate retreating portion at the upper end thereof. , Each of the left and right ends thereof is provided with an inward turning portion, and such a side plate is inserted into the inner surface of the upper frame member by the insertion plate surface retreating portion, and each inward turning portion of each outward turning portion is It is fitted into each folded recess, and the lower edge thereof is attached to the opening so as to be exposed on the outer surface of the lower frame member, so that it is structurally difficult for water to enter the opening from each part of the peripheral edge of the side plate, Water resistance can be obtained. Also, with such a structure, it is possible to reduce the number of fixing bolts to be used, and to attach the side plate.
It has the advantage that it does not take time and labor to remove it.
