Many parts of sewage facilities are constructed of concrete, and in order to prevent abrasion and corrosion of the concrete, they are usually designed to keep the flow velocity of sewage water within 3 m/sec. However, when constructing a pipe in an area where there is a topographical difference in height, it is necessary to provide a confluence manhole or a manhole in which the first flow velocity exceeds the above-mentioned velocity, and it is necessary to take some measures to prevent concrete abrasion and corrosion. Concrete protection measures will need to be provided.

In Fig. 3, a rubber plate 4 containing an iron plate 4a is stretched in the manhole 1, covering the surface of an invert part with a semicircular cross section that connects a pipe 2.3 with a head. The plate 4 is fixed to the concrete structure of the invert portion by a fixing member (not shown) such as a hole anchor. This iron-filled rubber plate 4 has a shape that corresponds to the shape of the invert part to which it is attached, but since it is difficult to cut the iron-filled rubber plate at the construction site, it is necessary to adjust the shape of each invert part. Based on this, the development diagram shown in Figure 3 (d) is created by design calculation for each manhole, and a rubber plate containing an iron plate is made in advance at the factory according to the shape of this development diagram and brought to the manhole and stretched.

In the conventional abrasion plate structure for concrete, as mentioned above, a development diagram is designed individually for each hole, and a rubber plate with steel plates is created in a factory according to the development plan and brought to the site. Design calculations are required for each hole, so it takes time to manufacture it, and even if it is formed into a predetermined shape through the time-consuming process of cutting and bending the steel-filled rubber plate according to the development drawing. However, due to errors in the installation of pipes at construction sites, they do not actually fit perfectly with the invert parts, and the installation often does not have a clean finish.

FIG. 1 is a partially enlarged side sectional view of one embodiment of the structure of a wear-resistant plate for concrete 1 according to the present invention, and FIG. 2 is a plan view of the main body of the wear-resistant plate. The wear-resistant plate main body 6 of the wear-resistant plate structure 5 for concrete includes a surface side rubber layer 7 with excellent wear resistance,
A hard rubber layer 8 containing reinforcing fibers is integrally provided on the inside thereof. The hardness of the surface side rubber layer 7 is H360~
70 is preferred; if the hardness is lower than this, the surface will be easily damaged, and if the hardness is higher than this, the abrasion resistance will decrease, which is not preferred. For example, 5BR (styrene butadiene rubber) can be used as the rubber grit having such hardness and sufficient wear resistance. Furthermore, the hard rubber layer 8 is not required to have wear resistance, but instead expands when force is applied in the direction in which the wear-resistant plate body 6 is peeled off from the concrete structure, and the mounting bolt 4 is pulled out. It is necessary to have sufficient hardness so that it does not occur. The hardness of the hard rubber layer 8 that satisfies such requirements is preferably in the range of H880 to H90, and as such hard rubber, rubber containing reinforcing fibers such as vinylon cloth-filled SBR can be used. In addition, in this embodiment, in order to prevent the completed wear-resistant plate body 6 from being bent due to the expansion and contraction of the front side rubber layer 7 during the manufacturing process of the wear-resistant plate body 6, the hard rubber layer 8 is further inside the hard rubber layer 8. The rubber layer 9 is also integrally formed. As this inner rubber layer 9, the same rubber as the front side rubber layer 7 can be used, for example, SBR. The total thickness of the wear-resistant plate main body 6 of this embodiment made of the three layers of rubber is 20 to 30 mm.

The surface of the front side rubber layer 7 is preferably embossed to prevent slipping so that workers can pass through it safely during construction and maintenance inspections.

In order to fix the wear-resistant plate main body 6 to the concrete 1/structure 10, a plurality of fixing member insertion holes 11 are formed in the wear-resistant plate main body 6. The wear-resistant plate main body 6 has a hole anchor 13 inserted into the fixing part 4A insertion hole]1,
It is fixed to the concrete structure]0 by a fixing member 12 consisting of a J bolt 14 and a washer 15. As is clear from FIG. 1, the fixing member insertion hole 11 has a stepped portion made of the hard rubber layer 8 such that the diameter of the upper part is larger than the diameter of the washer 15 and the diameter of the lower part is smaller than the diameter of the washer 5. 16 are formed.

First, at the construction site, the actual concrete structure]
A vinyl sheet or the like is applied to 0, a cut line is drawn along with the actual material, the vinyl sheet or the like is placed on the wear-resistant plate body 6, and the wear-resistant plate body 6 is cut along the cut line. After placing the plurality of wear-resistant plate bodies 6 cut in this manner at predetermined positions on the concrete 1/structure 10 and checking how well they fit, the concrete structure 0 corresponding to the fixing member insertion hole 11 is placed. A hole anchor driving hole is drilled at the position, and the hole anchor 1 is inserted through the fixing member insertion hole 11.
After driving in 3, remove (-4 bolt) 4 with washer] 5
The wear-resistant plate main body 6 is fixed to the concrete 1/structure 10 by screwing into the fitting hole anchor 13. At this time, the claw portion 15b of the washer 15 firmly bites into the stepped portion 6 made of a hard rubber layer, thereby increasing the anchoring strength of the wear-resistant plate body 6 to the concrete structure 10. Thereafter, a filler is filled in each fixing member insertion hole 11 and the gap between each wear-resistant plate main body 6 to form a flat surface, thereby completing the wear-resistant plate structure 5 for concrete.

Further, according to the present invention, the washer in the fixing member is formed with a claw portion extending in the circumferential direction, and when the fixing member fixes the wear-resistant plate body to a concrete structure, the claw portion of the washer is filled with reinforcing fibers. Because it bites into the stepped part made of a hard rubber layer, even if force is applied in the direction of the wear-resistant plate main body being torn off from the concrete structure, the rubber around the fixing member insertion hole will stretch and the mounting bolts will close to the fixing member insertion hole. This prevents the wear-resistant plate from being pulled out of the concrete structure, further increasing the anchoring strength of the wear-resistant plate body to the concrete structure.
