Abstract

A frame structure provided with a ring beam (9) that transmits the load on an element rotation type air preheater (8) that is a newly-installed implement to a load support point (P1) on an element fixed type air preheater that is an already-installed implement on a frame (6), wherein leaving the already-installed beam member as it is, the basic load transmitted to the leg of a column member is made to be substantially the same as in the period of construction before remodeling.

Example Embodiment

[0018] Hereinafter, embodiments of the present invention will be described with examples shown in the drawings.
[0019] Figure 2 to Figure 4 is an example of a mode for carrying out the present invention, and in the figure, the figure 1 The parts with the same symbols represent the same components, and the basic structure of the framework structure of the present invention is the same as the figure 1 The previous architecture shown is the same, but as Figure 2 to Figure 4 As shown, the example shown in this figure is characterized in that there is provided: a ring beam 9, which is relative to the load support point P1 of the fixed air preheater 7 on the frame 6 as a component of the existing machine, and transmits it as a newly installed machine. The mechanical component is the load of the rotary air preheater 8 .
[0020] In the case of the example shown in this figure, although the load of the rotary air preheater 8, which is a component of the newly installed machine, acts on the load support point P2 of the ring beam 9. But if image 3 and Figure 4 As shown, since it is the load support point P1 of the above-mentioned component-fixed air preheater 7 with respect to the installed beam member 4, the ring beam 9 is placed by the installed spacer 4a and the spacer 10 for level adjustment. Therefore, the load acting on the above-mentioned load supporting point P2 is transmitted to the existing beam member 4 of the frame 6 .
[0021] Moreover, as image 3 and Figure 4 As shown, the cross-sectional shape of the ring beam 9 is box-shaped, and a reinforcing rib 11 is attached to a portion corresponding to the load support point P1 inside the ring beam 9, and a lining plate 12 is attached to the inner surface as necessary.
[0022] Next, the operation of the above illustrated example will be described.
[0023] Although the load of the rotary air preheater 8, which is a component of the newly installed machine, acts on the load support point P2 of the ring beam 9, the load is transmitted to the frame 6 through the ring beam 9, which is an existing machine. Since the load supporting point P1 of the component-fixed air preheater 7 is located at the load support point P1, the load is transmitted to the foundation of the legs of the column members 1 and 2, unlike the case where the existing beam members 4 and 5 are removed and other beam members are added. The load is almost the same as the original state of the construction before the renovation.
[0024] Furthermore, in the example shown in this figure, the cross-sectional shape of the ring beam 9 is box-shaped, and therefore, it is not related to the long-term or short-term occurrence at the load support point P2 of the rotary air preheater 8, which is a component of the newly installed machine. It is sufficient to install a horizontal truss or the like without protruding to the outside against the horizontal force, and an already installed scaffold (not shown in the figure) for maintenance can be used.
[0025] In this way, the existing beam members 4 and 5 can be left, and the foundation load transmitted to the legs of the column members 1 and 2 can be almost the same as the state of the original construction before reconstruction, and can be used as it is. Installed scaffolding for maintenance.
[0026] The architectural structure of the present invention is not limited to the examples illustrated above, and various modifications can of course be made without departing from the scope of the subject matter of the present invention.
[0027] industrial applicability
[0028] As described above, in the frame structure of the present invention, since the existing beam members 4 and 5 can be left, the foundation load transmitted to the legs of the column members 1 and 2 can be almost the same as the state of the original construction before the reconstruction. Furthermore, since the existing maintenance scaffold can be used as it is, it can be applied to the replacement of the existing machine installed on the frame with the newly installed machine of a different form.
