Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a furnace wall loop surface, and particularly to a supporting device for an exterior material.

As shown in FIG. 1, the conventional furnace wall loop surface structure is such that an exterior material (deck plate) 1 is supported by a loop drain cover 2 and a loop end cover 3.

In recent years, as boilers have become larger, it has become increasingly difficult to walk along the loop surface of the furnace wall to inspect and monitor auxiliary equipment.
It is customary. When a patroller walks on the loop surface of the furnace wall, the load of the patroller is applied to the loop drainer cover 2a, and since the loop drainer cover 2a is made of a thin steel plate, the loop drainer cover 2a bends as shown in FIG. This has disadvantages in that it gives a sense of discomfort to patrollers, reduces the draining function, and allows rainwater to enter the heat insulating material 4. In addition, in recent years, it has become necessary to use an exterior material 1a made of a soft material (aluminum key stop plate) at the location of the exterior material indicated by reference numeral 1 in FIG. During the installation work of 1a, the soft exterior material (aluminum key stop plate) 1a is damaged at a pole, so an extra exterior material (aluminum key stop plate) 1a is required, and a lot of labor is required for the installation work. There was a drawback. Therefore,
As shown in FIG. 3, a sidewalk 14 is provided to eliminate the above-mentioned drawbacks, but the sidewalk has supporting posts 17.
However, since it penetrates the exterior material (deck plate) 1, installing the rain cover 9a prevents rainwater from entering. However, there are many sidewalk support posts 17, and the types of rain cover 9a are This resulted in a disadvantage of poor workability.

This invention eliminates the drawbacks of the prior art described above, and proposes a means for constructing a furnace wall exterior material with good workability without reducing the strength of the furnace wall exterior material, and a means for omitting the accompanying walkway. The purpose is to

In short, this invention achieves the above object by combining a small diameter steel pipe with a product processed into a T-shape so that it can be easily installed as a support for an exterior material. Features.

Next, one embodiment of the present invention will be described with reference to FIGS. 5 to 7. As shown in FIG. 5, a loop surface exterior material (deck plate) 1 is supported by a loop draining cover 2, a roof end cover 3, and a vibe support 11.

The loop drainer recoverer 2 is attached to an L-shaped support 6 that is welded and fixed to the inner casing 5. A nut 7 is welded in advance to the inner casing side of the L-shaped support 6, and a bolt 8 is screwed into the threaded portion of the nut 7 to be fixed. The roof end cover 3 is attached to an L-shaped support 6a that is welded and fixed to the inner casing 5. Said L
A nut 7 is welded to the support 6a in advance, and a bolt 8 is screwed into the threaded portion of the nut 7 to secure the support 6a.
By welding and fixing the stud bolts 10 to the roof end cover 3, attaching the exterior material (deck plate) 1, and tightening the rain cover 9 with the nuts 7a, the loop drain cover 2 and the vibe support 11 slide, so the inner The difference in elongation of the casing 5 can be absorbed. On the other hand, as shown in FIG. 7, the means for supporting the small diameter steel pipe is such that the vibe support 11 is welded and fixed to the inner casing 5 and the T-shaped joint 12 is welded to the vibe support 11a. Insert into the T-shaped joint 12. Vibrator base 11a. Welding of the 5T-shaped joint 12 is carried out by connecting the water system to the end A of the loop drain cover 2 shown in FIG. 5 and the end A of the roof end cover 3 shown in FIG. The base 11a and the -T-shaped joint 12 are fixed by welding. Therefore, the height of the tube outer surface of the vibe support 11 can be easily attached to any height of the loop slope of the exterior material (deck plate) 1 from the inner casing 5. On the other hand, the difference in elongation between the vibrator supports 11a is T
Since the j-shaped joint 12 and the vibe support 11 are not fixed by welding and slide, the difference in expansion can be absorbed.
FIG. 6 shows another embodiment of the present invention, and the same parts as in FIG. 5 are designated by the same reference numerals.

The two differences from FIG. 5 are that the distance between the water wall pipe 13 and the inner casing 5a is longer than that in FIG.
1a and T-shaped joints 12 in two rows, it is suitable for reducing the amount of deflection of the exterior material (deck plate) 1 on the loop surface of the furnace wall, and the exterior material on the loop surface of the furnace wall is made of soft exterior material ( Also suitable for aluminum keystone plate) 1a. By implementing this invention, (1) the support device can be easily installed at any location;

(2) Since the load applied to the loop draining recoverer is reduced, the draining slope of the loop surface of the furnace wall can be secured and rainwater will not enter. (3) Even if the exterior material of the loop surface of the furnace wall is a soft material, it can be used satisfactorily. In addition, since it can function sufficiently as a patrol inspection walkway, the walkway can be omitted and rain cover etc. are not required.

(4) Sufficient stretch absorption between support points ・(5) Good exterior appearance It has various effects such as.
