Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a steel frame structure suitable for a T-shaped waste treatment facility building having a vertical furnace such as a fluidized fluid furnace or a melting furnace.

[Prior art]

Conventionally, as shown in Fig. 1, the steel frame structure of a T-shaped vertical furnace type waste treatment facility building is as follows: Garbage pit rear wall ridge floor assembly 2H and lower house ridge roof assembly 3H are connected to the intermediate part in the height direction of the garbage pit, and garbage pit side girder row frame assembly 1F of crane ridge 1, crane ridge roof assembly 1H, and garbage pit rear wall ridge. Girder row frame 2F, garbage pit rear wall ridge floor group 2H, lower house ridge girder row frame 3B, and lower house ridge roof group 3
Each H is equipped with a brace V, and the input hopper side girder row frame 1B is arranged into a vertical furnace 4 and an air preheater, gas cooler, etc. 8 arranged in a direction perpendicular to the extension direction of the garbage pit 5.
A steel frame structure erected between the two is known.

[Problem that the invention attempts to solve]

However, in the conventional steel structure, the bracing in the lower half of the loading hopper side girder row frame 1B in the crane building 1 is extremely obstructive to the installation, operation, and maintenance work of the waste treatment equipment. be.

As a countermeasure against this, the input hopper side column row frame 1
It is conceivable to omit the brace of B and make the input hopper side girder row frame 1B a rigid frame structure.
In this case, since the column length is very long, the cross section of the constituent members becomes very large, which has the disadvantage that the cost of steel construction increases considerably.

[Purpose of the invention, structure]

The purpose of this invention is to provide a steel frame structure for a T-shaped vertical furnace waste treatment facility building that can advantageously solve the above-mentioned problems. Garbage pit rear wall ridge floor assembly 2H and lower house ridge roof assembly 3H are connected to the intermediate part in the height direction of the input hopper side girder row frame assembly 1B of the crane ridge 1 in the vertical furnace type waste processing facility building, and the crane ridge 1 Garbage pit side girder row frame 1F,
Crane ridge roof assembly 1H, garbage pit rear wall ridge girder row frame assembly 2F, garbage pit rear wall ridge floor assembly 2H, lower house ridge girder row frame assembly 3B, and lower house ridge roof assembly 3H are each T-shaped with braces V. Arrangement In the steel frame structure of the vertical furnace type waste processing facility building, the input hopper side girder row frame assembly 1B is provided with braces V only in its upper half, and the input hopper side girder row frame assembly 1B is not equipped with braces. The lower half of the column is located in the steel frame structure of the T-shaped vertical furnace type waste treatment facility building, which is characterized in that it is disposed between the vertical furnaces 4 lined up along the extension direction of the garbage pit.

〔Example〕

Next, this invention will be explained in detail using illustrated examples.

FIGS. 2 and 3 show an embodiment of this invention, in which charging hoppers 7 are arranged continuously in the direction perpendicular to the extending direction of the garbage pit 5 and the traveling direction of the garbage pit crane 6 above it. A large number of vertical furnaces 4 and air preheaters/gas coolers 8 are installed in parallel in the extending direction of the garbage pit 5 and in the running direction of the garbage pit crane 6, and each vertical furnace 4 is connected to the garbage pit 5, etc. The inter-beam direction frames in the steel structure of the garbage treatment facility building, which are installed at intervals in the garbage pit extension direction and cover each of the above-mentioned equipment, cover the garbage pit 5 and the input hopper 7, and the garbage pit crane 6 is mounted on top. A gate consisting of a gate-shaped Ramen in the crane building 1, a half-gate-shaped Ramen in the garbage pit rear wall building 2, and a half-gate-shaped Ramen in the lower house building 3, which are connected to the middle part of the side pillar of the input hopper in the gate-shaped Ramen. It is composed of a half-gate type joint frame, and the girder row axis is connected to the loading hopper side girder row axis of the crane building 1, which is located below the garbage pit rear wall ridge floor assembly 2H and the lower house ridge roof assembly 3H. No bracing is provided in the lower half of group 1B, and only the bracing V is provided in the upper half.
is provided, and the lower half column of the loading hopper side girder row frame 1B of the crane building 1 is arranged between the adjacent vertical furnaces 4, and the garbage pit side girder row frame 1F of the crane building 1, the garbage pit side girder row frame 1F, A brace V is provided on the rear wall ridge girder row frame 2F and the lower house ridge girder row frame 3B, and these frames 1F, 2F, 3B and the frame 1
Braces V are also provided in the upper half of the crane ridge roof assembly 1H, the garbage pit rear wall ridge floor assembly 2H, the lower house ridge roof assembly 3H, and the input hopper side girder row frame assembly 1B of the crane ridge 1, which connect the crane ridge B. There is.

In the above-mentioned embodiment, the case where the lower building 3 does not cover the dust collector 9 is shown, but this idea can also be implemented when the lower building 3 covers the dust collector 9. In the figure, 10 is a platform, 11 is a platform building, 12 is a chimney, and G
is a girder or beam, and S is a stud or bundle.

[Effect of idea]

According to this invention, a garbage pit rear wall ridge floor assembly 2H and a lower house ridge roof assembly 2H are placed at the intermediate part in the height direction of the loading hopper side girder row frame assembly 1B of the crane building 1 in a T-shaped vertical furnace type waste processing facility building. Group 3H is combined, garbage pit side girder row frame group 1F of crane building 1,
Crane ridge roof assembly 1H, garbage pit rear wall ridge girder row frame assembly 2F, garbage pit rear wall ridge floor assembly 2H, lower house ridge girder row frame assembly 3B, and lower house ridge roof assembly 3H are each T-shaped with braces V. Arrangement In the steel frame structure of the vertical furnace type waste processing facility building, the input hopper side girder row frame assembly 1B is provided with braces V only in its upper half, and the input hopper side girder row frame assembly 1B is not equipped with braces. Since the lower half of the column is placed between the vertical furnaces 4 that are lined up along the longitudinal direction of the garbage pit, functionality for installation, operation, and maintenance of the garbage treatment equipment can be greatly improved. The effect that can be obtained is obtained.
