In the method of press-fitting the reinforcing bars between each slit and stripping and dismantling them into blocks, if there are reinforcing bars buried perpendicular to the part to be stripped and dismantled, 1. First, excavate around the reinforcing bars and cut the edges from the main body. This relates to a construction method characterized by performing stripping and demolition work after removing resistance from reinforcing bars and the like.

である。When peeling and dismantling the surface layer of a concrete structure,
Vertically, slits of a predetermined depth are made at appropriate intervals on the surface layer.
We previously developed a method in which the concrete in slit 1 is peeled off into blocks by creating a crack at the bottom of the slit by pressing a wedge into the slit and pushing the slit open, as shown in Figure 8. As shown in Figure 2, if reinforcing bars are buried perpendicular to the surface of the part of concrete structure a that is to be peeled off, even if wedges d are press-fitted into slits C, the reinforcing bars will prevent peeling and demolition. Therefore, the present invention
In order to make the work easier even in such cases,
After cutting the reinforcing bars etc. from the main body f! ! The structure is characterized by being peeled and dismantled by equipment, and its configuration will be explained with reference to the embodiment of the drawing. (1) is a reinforced concrete structure, and (21 is a structure perpendicular to the peeling surface buried inside the If there are reinforcing bars buried in the area to be peeled and dismantled, first confirm the location with a metal detector, etc., and then use a diamond cutting blade A at the tip, for example, as shown in Figure 2. As shown in Fig. 1, the core drill B equipped with An excavation groove (3) is provided around the reinforcing bar (2) as shown in the figure, and a cylindrical body (
After forming the slit (5), the slit (5) is pushed open by moving gt61 into and out of the slit (51) provided at a predetermined position as shown in FIG.
will occur. At this time, since an inward direction (31) is provided around the reinforcing bar (2), a cylindrical body (4) centered on the reinforcing bar (2) is formed.
As shown in Figure 6, the area around it can be peeled off in a block shape regardless of the cylindrical body (4
) along with the reinforcing bars (21), and as shown in FIG. 7, the surface layer of a predetermined structure I) is completely peeled off and dismantled.

できる。As described above, according to the construction method of the present invention, even if reinforcing bars are buried inside the part of the surface layer of a reinforced concrete structure that should be peeled off and demolished, grooves can be cut around the reinforcing bars by pre-caulking. By straining and separating it from the main body, it is possible to easily and reliably perform peeling and dismantling work at a predetermined location by simply press-fitting a wedge into the slit without encountering resistance from reinforcing bars or the like.

リート構造物等の表層部剥離解体工法。(1) When peeling and dismantling the surface layer of a reinforced concrete structure, etc., the area around the reinforcing bars, etc., which are buried in the peeled part and perpendicular to the peeled surface, is removed from the surface of the structure using an appropriate core pit etc. After excavating to a deep depth and separating the pillars from the main body, wedges are press-fitted into slits made at a predetermined depth from the surface to separate blocks between the slits, and finally, the pillars are removed as appropriate. A distinctive feature of this method is the peeling and demolition of the surface layer of reinforced concrete structures.
