The structures of the coke oven temporary shed 100 and side wall 101 and the members constituting them according to the present embodiment have been described above. Hereinafter, a method for constructing a temporary coke oven shed 100 according to the present embodiment will be described.

[Method of constructing a temporary shed]
A method for constructing a temporary coke oven shed 100 according to this embodiment will be described with reference to FIGS. 10A to 10D. FIGS. 10A and 10B are flowcharts showing a method for constructing a temporary coke oven shed 100 according to the present embodiment. Moreover, FIG. 10C is a diagram showing the construction work of the side wall 101 of the temporary coke oven shed 100 according to this embodiment. Moreover, FIG. 10D is a diagram showing the fixing work of the panel member 120 of the coke oven temporary shed 100 according to the present embodiment.

As shown in FIGS. 10A and 10B, in the method for constructing a temporary coke oven shed 100 according to the present embodiment, construction materials including panel members 120 are first transported to the construction site of the temporary shed 100. (S101). Subsequently, column members including the column members 110 and the intermediate column members 115 are erected at predetermined intervals at the planned installation locations on the side wall 101 of the temporary shed 100 (S103). After that, the side wall 101 is formed using the panel member 120 and the column member (S105).

Here, the process of forming the side wall 101 in step S105 will be described in detail with reference to FIGS. 10B and 10C. In the process of forming the side wall 101, as shown in FIG. 10C, the panel members 120 carried in are moved one by one above the column members 110 using a lifting device such as a crane C. Thereafter, the panel member 120 is inserted between the pair of pillar members 110, 110 such that both horizontal ends of the panel member 120 are inserted into the pair of opposing grooves 130, 130 provided in the pair of pillar members 110, 110 from above in the vertical direction. It is inserted between the members 110, 110 and gradually moved downward (in the direction of the arrow in FIG. 10C) (S113).

In this way, the plurality of panel members 120 are inserted one by one between the pair of column members 110, 110. When the panel member 120 is inserted, both horizontal ends of the panel member 120 are guided by the grooves 130. The inserted panel member 120 is moved downward until it contacts the stopper 113 provided at the lower end of the groove 130 or the panel member 120 that has already been inserted. As a result, a plurality of panel members 120 are stacked vertically between the pair of pillar members 110, 110 (S115).

The operations of step S113 and step S115 are repeated until the stacked panel members 120 reach a predetermined height (S117). After the panel members 120 are stacked to a predetermined height, the formation of the side walls is completed.

Next, returning to FIG. 10A, the post-process of the above side wall forming step (S105) will be described. Panel member 120 is fixed to column member 110 (S107). In this fixing step S107, the scaffolding S is first installed. Next, for example, as shown in FIG. 10D, the worker W performs a work of fixing the panel member 120 to the column member 110 while standing on a simple scaffold S. Specifically, the worker W uses the tool K to tighten the bolts 141 as the fixing member 140 with the nuts 142 from the indoor side of the side wall 101 toward both horizontal ends of the frame section 121 inserted into the groove section 130. screw it in and push it in. As a result, as shown in FIG. 8, the tip 141a of the bolt 141 comes into contact with the second frame 121b. Further, when the bolt 141 is pushed in, the second frame 121b is pushed in through the bolt 141 and comes into contact with the inner wall 131, so that the panel member 120 is fixed to the column member 110. This fixing work is performed on a plurality of stacked panel members 120.

The fixing work may be performed after all the panel members 120 are stacked, or may be performed each time one panel member 120 is installed. Further, at the same time as the fixing work, a work of fastening the fastening member 150 between the intermediate column member 115 and the horizontally intermediate portion of the panel member 120 may be performed simultaneously.

After the side wall 101 is formed by the side wall forming step (S105) and panel fixing step (S107) described above, the roof 103 of the temporary shed 100 is formed on the upper part of the side wall 101 (S109). Next, after the side wall forming step (S105), panel fixing step (S107), and roof forming step (S109) are completed, the working scaffold is removed (S111), and the construction of the temporary shed 100 is completed.

Note that both the first side wall 101a and the second side wall 101b (see FIGS. 1 and 2) of the temporary shed 100 can be constructed by the above method. Furthermore, not only the side wall 101 of the temporary shed 100 but also the lower shed 200 can be constructed in a similar manner.

(effect)
According to the construction method of the temporary shed 100 for a coke oven according to the present embodiment, the panel members 120 constituting the side wall 101 are unitized and stacked to form the side wall 101. Compared to the conventional method of attaching to the frame, construction time can be shortened and work costs can be significantly reduced.

That is, in the past, after installing external scaffolding around the shed skeleton, workers attached external wall materials directly to the skeleton, which required a large amount of man-hours and work costs to install and dismantle the scaffolding. Furthermore, the installation and removal of exterior wall materials itself was a cumbersome and labor-intensive task. On the other hand, according to the present embodiment, the side wall 101 can be easily and quickly formed by lifting the unitized panel members 120 with a crane or the like and stacking them, thereby eliminating the need for external scaffolding, shortening the construction period and reducing costs. The number of staff can also be reduced. Furthermore, there is no need for the complicated work of installing external wall materials. Further, in the dismantling work of the temporary shed 100, it is possible to similarly shorten the construction period and reduce costs.

Further, according to the present embodiment, the panel member 120 is formed into a unit by including the frame portion 121 and the wall plate portion 123, and is reduced in weight and size while maintaining rigidity. Therefore, even if a plurality of panel members 120 are stacked, it is possible to prevent the panel members 120 from being deformed or destroyed by the load, and the construction method according to the present embodiment can be realized. Further, according to this embodiment, since the panel member 120 has rigidity due to the frame portion 121, there is no need to separately provide a furring material for attaching the panel member 120 between the column members. That is, conventionally, a beam called a rim member was provided between the pillars of the frame to support the intermediate portion of the outer wall material and to which the outer wall material was attached. According to this embodiment, since the frame portion 121 of the panel member 120 supports the wall plate portion 123 as a rim material, there is no need to provide a rim material in the skeleton.

Furthermore, according to this embodiment, since the panel member 120 is unitized, the panel member 120 can be reused at another site.

Further, according to the present embodiment, since the groove portions 130 are provided in the vertical direction on both sides of the column member 110, when inserting the plurality of panel members 120 between the pair of column members 110, 110, the panel members 120 Easy to stack.
