Description

[Technical field]

[0001] The present disclosure relates to a curing structure and a curing method, and more particularly to a curing structure and a curing method for an opening formed in a target material. [Background technology]

[0002] When performing work such as replacing a target material with a new target material in an opening in a target material such as a roofing material, the opening needs to be protected to prevent workers from falling through the opening. Conventionally, when protecting an opening, a method of protecting the opening from above has been used, for example, a method of placing a scaffolding board on the opening, a method of laying a net on the opening, or a method of surrounding the opening with a temporary handrail. In addition, when the lower part of the opening can be accessed, a method of attaching a net to the lower part of the opening has also been used, for example, as shown in Patent Document 1.

[0003] [Patent Document 1] JP 2003-166350 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, when covering an opening from above, it is difficult to carry out work on the opening (such as replacing it with new materials) while covering it, because the opening is covered with scaffolding boards, laid nets, temporary handrails, etc. For this reason, it is necessary to remove the covering during work, which increases the risk of falling.

[0005] Furthermore, when covering an opening from below, there are problems such as restrictions on access to the space below the opening, which can restrict construction work or require restrictions on work in the space below, as well as the cost of setting up temporary scaffolding to attach the net.

[0006] The object of the present disclosure, made in consideration of the above circumstances, is to provide a curing structure and a curing method that enable work to be performed on an opening from above the opening while the opening remains cured. [Means for solving the problem]

[0007] The curing structure according to one embodiment of the present disclosure is A curing structure for an opening formed in a target material, A support material disposed around the opening; The opening is fixed to a support material with a gap in an out-of-plane direction of the opening, and a covering member that covers the opening.

[0008] A curing method according to an embodiment of the present disclosure includes: A method for curing an opening formed in a target material, comprising the steps of: a curing step of disposing a covering member so as to cover the opening with a gap in an out-of-plane direction relative to the opening; and a renewal process of inserting a new construction material through the gap and sealing the opening with the new construction material. Effect of the Invention

[0009] According to the present disclosure, it is possible to provide a curing structure and a curing method that enable work to be carried out on an opening from above the opening while the opening remains cured. [Brief description of the drawings]

[0011] Hereinafter, a curing structure and a curing method according to an embodiment of the present disclosure will be described with reference to the drawings. In each drawing, the same or corresponding parts are given the same reference numerals. In the description of this embodiment, the description of the same or corresponding parts will be omitted or simplified as appropriate.

[0012] The present disclosure particularly relates to a curing structure and a curing method for an opening formed in a target material. Here, the target material is, for example, a roof material, a wall material, a floor material, etc. of a building. The opening may be in a state where it has already been formed (for example, due to damage to the target material), or may be formed by removing an existing target material 16 (see FIG. 5). An example in which the target material is a roof material will be described below.

[0013] (Curing method) Fig. 1 to Fig. 6 are diagrams for explaining steps 1 to 6 of the curing method according to this embodiment. In each of Fig. 1 to Fig. 6, the left diagram is a side view of the work area, and the right diagram is a plan view from above. Each step will be described below with reference to each diagram.

[0014] First, as shown in FIG. 1, in step 1, the support material 11 is installed on the roof material (target material). In this embodiment, the support material 11 is a plurality of posts (stanchion poles) arranged at intervals from each other, but is not limited to this. In this embodiment, each of the plurality of support materials 11 is erected and fixed to the roof material (target material). In addition, a fixing member 12 for fixing a covering member 13 (see FIG. 2), which will be described later, is provided between the plurality of support materials 11. In this embodiment, the fixing member 12 is a wire stretched between the posts, but is not limited to this. In addition, in the example of FIG. 1, a fixing member 12 is provided on each of the two sets of support materials 11, and two fixing members 12 are provided in total. However, the number of support materials 11 and the number of fixing members 12 are not limited. In addition, as long as it is possible to loosen and tighten the fixing member 12 and adjust the height of the fixing member 12, the method of connecting the fixing member 12 to the support material 11 is not limited. For example, the fixing member 12 may be directly fastened to the support material 11, or may be connected via a clamp lever or the like.

[0015] In this embodiment, roof material replacement work is performed in a work target area 20, which is a part of the roof material (target material). The work target area 20 becomes an opening by removing the existing target material 16 (see FIG. 5). Therefore, it is necessary to cover the work target area 20 from above so that the worker 30 (see FIG. 3) can work on the work target area 20 while preventing the worker 30 from falling and ensuring safety. Here, in FIG. 1 to FIG. 4, for ease of viewing, the illustration of the existing target material 16 (see FIG. 5) is omitted and only the work target area 20 is shown. Also, the direction along the surface of the work target area 20 may be referred to as the in-plane direction. Also, the direction perpendicular to the surface of the work target area 20 may be referred to as the out-of-plane direction. In this embodiment, the out-of-plane direction corresponds to the height direction.

[0016] As shown in FIG. 2, in step 2, the covering member 13 is attached between the two fixing members 12 to cover the work area 20. It is preferable that the covering member 13 covers the entire work area 20. In this embodiment, the covering member 13 is a net, but is not limited to this. As another example, the covering member 13 may be a sheet or the like. However, it is preferable that the covering member 13 is a member having holes such as a net so that visibility and work can be performed through the covering member 13. In step 2, the fixing member 12 is loosened, and the covering member 13 is placed on the work area 20 without any gap. Here, the method of fixing the covering member 13 to the fixing member 12 is not limited. For example, the covering member 13 may be directly tied to the fixing member 12, or may be connected via a carabiner or the like.

[0017] As shown in Fig. 3, in step 3, a scaffolding board 14 is installed on the covering member 13. Also, in step 3, a worker 30 pulls out the bolts that secure the existing target material 16 (see Fig. 5) in the work target area 20 from above the covering member 13.

[0018] As shown in FIG. 4, in step 4, a curing step is performed in which the covering member 13 is arranged to cover the work target area 20 with a gap h in the out-of-plane direction (height direction) relative to the work target area 20. For example, the gap h may be created by increasing the tension of the fixing member 12 to lift the covering member 13 from the work target area 20. The range of the gap h will be described later. Also, as in step 4 of this embodiment, when there is still an existing target material 16 (see FIG. 5) (when no opening has been formed), the curing step also includes the work of removing the existing target material 16 (see FIG. 5) to form an opening. That is, the curing step includes steps 4 and 5 in this embodiment, and the covering member 13 is arranged to cover the opening with a gap h relative to the opening.

[0019] As shown in Fig. 5, in step 5, the existing target material 16 is removed from the gap h to form an opening. At this time, the corrosion state is inspected, and the existing target material 16 may be replaced with a new target material 17 (see Fig. 6) as necessary. As shown in Fig. 5, in the removal work of the existing target material 16, a support material 15 may be used to support the existing target material 16 during removal in order to prevent the existing target material 16 from falling. The support material 15 is, for example, a single pipe, but is not limited to this. Here, in the right diagrams of Figs. 5 and 6, the covering member 13 is shown in a see-through manner for ease of viewing.

[0020] The gap h between the covering member 13 and the opening can be adjusted by loosening or tightening the fixing member 12 and adjusting the height of the fixing member 12 relative to the support member 11 as described above, but it is preferable that the gap h is more than twice the thickness of the roof material (target material) so that the roof material (target material) can be replaced. As an example, the gap h may be 350 mm or more. Here, the gap h is the "gap between the covering member 13 and the opening at the periphery of the opening". It is not necessary for the gap h to be between the covering member 13 over the entire surface of the opening. If there is a gap h between the opening and the covering member 13 at least around the periphery of the opening, the roof material (target material) can be replaced. In this embodiment, the height of the lowest position of the fixing member 12 (the part where the distance between the roof material and the fixing member 12 is the narrowest) is set to be more than twice the thickness of the roof material (target material). In addition, from the viewpoint of preventing falls from the gap h, it is preferable that the upper limit of the gap h is around the waist of the worker 30. As an example, the gap h may be 1 m or less. Here, the upper limit of the gap h may be adjusted depending on the size (area) of the covering member 13 relative to the opening.

[0021] As shown in Fig. 6, in step 6, a renewal process is performed in which a new roof material, a new installation target material 17, is inserted through the gap h and the opening is blocked by the new installation target material 17. For example, in step 6, the worker 30 may attach the inserted new installation target material 17 to the opening to block the opening, then remove the covering member 13 and fix the new installation target material 17 with a bolt.

[0022] Here, the curing method according to this embodiment does not need to include all of steps 1 to 6, but only needs to include at least the curing step and the renewal step. In this embodiment, in the curing step, the covering member 13 is placed on the existing target material 16, and then the existing target material 16 is removed to form an opening in the target material. However, the curing method according to this embodiment can also be applied when an opening has already been formed, for example, due to damage to a roof material. At this time, in the curing step, the covering member 13 is placed so as to cover the opening, with a gap h in the out-of-plane direction from the already formed opening.

[0023] (Curing structure) The curing structure of this embodiment formed by the above curing method comprises a support material 11 installed around the opening, and a covering member 13 fixed to the support material 11 with a gap h in the out-of-plane direction relative to the opening, covering the opening.

[0024] Here, the multiple support materials 11 installed around the opening have different intervals in the vertical and horizontal directions in a plan view. In other words, the multiple support materials 11 are arranged at narrow intervals in one in-plane direction of the work area 20, and are arranged at wide intervals in the other in-plane direction of the work area 20. Here, the one in-plane direction of the work area 20 is the insertion direction of the new target material 17 when attaching the new target material 17 to the opening. The other in-plane direction is a direction intersecting the insertion direction and is parallel to the direction in which the fixing member 12 is stretched. In the one in-plane direction of the work area 20 (vertical direction in the right diagrams of Figures 1 to 6), the distance from the work area 20 (opening) to the support materials 11 is short, so that the existing target material 16 can be easily removed and the new target material 17 can be easily inserted along this direction. Furthermore, in other directions within the plane of the work area 20 (horizontal directions in the right drawings of Figs. 1 to 6), the distance from the work area 20 (opening) to the supporting material 11 is long, so space can be secured inside the curing structure for the worker 30 to work. In this way, the spacing between the multiple supporting materials 11 in one direction (the insertion direction of the newly installed material 17) in a plan view is narrower than the spacing between the multiple supporting materials 11 in the other direction (the direction intersecting with the one direction), making it easier for the worker 30 to work.

[0025] As described above, the curing structure and curing method according to this embodiment are configured and processed as described above, and the covering member 13 that covers the opening is attached to the opening with a gap h in the out-of-plane direction of the opening. Therefore, the covering member 13 prevents the worker 30 from falling from the opening, and the worker can work on the opening through the gap h between the opening and the covering member 13. In other words, the worker can work on the opening from above while the opening is kept cured.

[0026] Although the embodiments of the present disclosure have been described based on the drawings and examples, it should be noted that those skilled in the art can easily make various modifications or corrections based on the present disclosure. Therefore, it should be noted that these modifications or corrections are included in the scope of the present disclosure. For example, the functions included in each component or each step (process) can be rearranged so as not to be logically inconsistent, and multiple components or steps can be combined into one or divided. It should be understood that these are also included in the scope of the present disclosure. [Explanation of symbols]
