A cable introduction part 6 for supplying a current to electric components arranged inside the protective chamber 1 is attached to the side wall 2.

3a to 3d, the side wall element S is shown.
Different wall elements in the form of a ceiling element D of equal width, a floor element B, and a corner element E, preferably with lateral portions corresponding to the width of the side wall element S, are shown. From FIG. 2, the structure of these wall elements can be seen in cross section, and from FIGS. 4A and 4B:
The connecting area of the wall element can be seen. On this basis, the side wall element S, the ceiling element D and, correspondingly, the corner element E are also made of steel sheet outer cover 2.1.
It consists of 3.1. As a result, a box-shaped structure is formed, and between the outer cover bodies 2.1; 3.1,
Since a plurality of fire protection layers I, II, III made of insulating material having a blocking action in the event of a fire are housed, the maximum permissible limit load of the information technology device, for example 90 minutes, is not exceeded.

The corner area between the side wall element S and the ceiling element D has an angular lining profile forming profile 2.2.
Are covered by. In this case, the vertically downwardly directed legs of this profiled profiled material 2.2 extend beyond the connection between the side wall element S and the ceiling element D. Since the edges of the side wall element S and the ceiling element D that abut against each other are completely L-shaped, the side wall element S and the ceiling element D maintain an easy and satisfactory seal. Can be joined together. Between the longitudinal side portion of the side wall element S and the longitudinal side portion of the ceiling element D, an expansion seal member 2.5 arranged at the center of the cross section, and a lateral side of the expansion seal member 2.5. Of the heat-resistant seal member 2.6, the seal band member 2.7 arranged outside, and the seal band member 2.7 and the heat-resistant seal member 2.6. A sealing means with a sealing compound 2.8 is arranged.
With this seal structure, the critical joint portion is formed to be fireproof. The sealing means is followed on the end side with respect to the wall element by a coupling tongue 2.4.

In order to hold the wall elements in the transition region in a simple and reliable manner so that they do not separate from each other, the outer jacket 2.1 is provided with an upward cone, as can be seen from FIGS. 4A and 4b. A connecting element 2.9 is formed with a groove that extends laterally outwards.
For the coupling element 2.9, a correspondingly adapted, upwardly tapering closing element 1 for engaging in the groove is provided.
