Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sheet for connecting projection sheets, and in particular, when a plastic sheet or a rubber sheet used for corrosion resistance of concrete structures or for repairing deteriorated parts is attached to a concrete structure, the sheets are arranged next to each other. The present invention relates to a connecting sheet suitable for connecting sheets together.
[0002]
[Prior art]
A plastic or rubber sheet having excellent corrosion resistance may be attached to the surface of the concrete structure to improve the durability of the concrete structure. In this case, simply attaching a flat sheet to the surface of the concrete structure may cause the sheet to peel off and prevent the original purpose from being achieved. Has been proposed (Japanese Patent Laid-Open No. 8-261357).
[0003]
[Problems to be solved by the invention]
Since the sheet has a certain width, in order to attach the sheet to the entire surface of the concrete structure having a planar spread, the sheets having a certain width must be adhered side by side in parallel. As a result, a butt surface is generated between the sheets arranged next to each other, so that the butt surface of the same quality as that of the sheet is applied and applied to cover the butt surface, or the butt surface is heat-welded as it is. In this way, peeling in the vicinity of the abutting surface is prevented. However, in the case of a sheet with protrusions, the rigidity is increased due to the protrusions on the entire back surface, so that for example, if there is a bend, it is difficult to correct this by the above-mentioned hand, and peeling is likely to occur in the vicinity of the abutting surface . In addition, a lot of work is required for the work for the hand.
[0004]
The present invention provides a connecting sheet for a sheet with protrusions, which can improve workability when improving corrosion resistance by the sheet and hardly cause peeling.
[0005]
[Means, actions and effects for solving the problems]
The present invention is a sheet for connecting a first sheet having protrusions over the entire back surface and a second sheet having protrusions over the entire back surface, wherein the first sheet and the second sheet are connected to their respective ends or sides. The first portion extends so as to cover a part of the first sheet from the abutting surface when being abutted at the portion, and the second portion extends so as to cover a part of the second sheet from the abutting surface. The first portion has a plurality of holes that respectively match the plurality of protrusions of the first sheet, and the second portion has a plurality of holes that respectively match the plurality of protrusions of the second sheet. The connecting sheet is disposed on the back surface of the first sheet and the second sheet by fitting the corresponding protrusions of the first sheet and the second sheet into the holes.
[0006]
When the first sheet and the second sheet are to be coupled, for example, an adhesive is applied to the surface of the coupling sheet, and the corresponding protrusions of the first sheet and the second sheet are fitted into the holes of the coupling sheet. The first sheet and the second sheet are connected to each other, the first sheet and the connecting sheet are pasted together, and the second sheet and the connecting sheet are pasted together.
[0007]
Since the first sheet and the second sheet are connected through the connection sheet using the protrusions of the protrusion-equipped sheet, the operation is simple. In addition, since the projections of the first sheet and the second sheet are fitted in the holes of the connecting sheet, the connecting sheet is the first sheet or the second sheet, even if the bends are attached to the first sheet or the second sheet. The first sheet and the second sheet are corrected and held, and peeling in the vicinity of the butted surface can be suppressed. In addition, since the connecting sheet has a plurality of holes aligned with the plurality of protrusions of the first sheet and the second sheet, the connecting sheet is not displaced in the state where the connecting sheet is connected by the connecting sheet. And the 2nd sheet | seat can be hold | maintained in a suitable connection state.
[0008]
The connection sheet preferably has at least one protrusion on the back surface.
[0009]
Depending on the distance from the abutting surface to the protrusion of the first sheet or the second sheet, the protrusion is not present between the protrusion of the first sheet and the protrusion of the second sheet fitted into the hole of the connecting sheet. An area may be generated and the connecting sheet may be lifted from the concrete structure. By providing protrusions on the back surface of the connecting sheet, the connecting sheet can be brought into close contact with the concrete structure.
[0010]
The present invention is also a sheet for connecting a first sheet having a protrusion over the entire back surface and a second sheet having a protrusion over the entire back surface, wherein the first sheet and the second sheet are connected to each end or A first portion extending so as to cover a part of the first sheet from an end portion or a side portion of the first sheet when arranged so as to be spaced at a side portion; and an end portion or a side portion of the second sheet To a second portion extending so as to cover a part of the second sheet, and a third portion covering the gap. The first portion has a plurality of holes that respectively match the plurality of protrusions of the first sheet, and the second portion has a plurality of holes that respectively match the plurality of protrusions of the second sheet. The connecting sheet is disposed on the back surface of the first sheet and the second sheet by fitting the corresponding protrusions of the first sheet and the second sheet into the holes.
[0011]
In some cases, such as when there are irregularities in the concrete structure, the end or side of the first sheet and the end or side of the second sheet may not be matched. In such a case, the end portion or side portion of the first sheet and the end portion or side portion of the second sheet are arranged at an interval, and the first sheet and the second sheet are formed using a band-shaped connecting sheet. The original purpose can be achieved by connecting.
