The first substrate 10 and the second substrate 20 can be temporarily assembled so that they can be separated and moved in the facing direction A by loosening the plurality of bolts 50, and can be relatively immovable by tightening the plurality of bolts 50. This assembly is possible.

As shown in FIG. 1, first, the second split substrate 40 is attached to the side surface S3 in a state where the two bolts 50 inserted into the second extension portion 22 and the second split extension portion 42 are loosened. Fully tighten according to the height to be used.

Next, with the adhesive mat 63 covered with a release sheet (not shown), the adhesive mat 63 with the release sheet is attached to the side surface S3 so as to be in close contact with the side surface S3. With the adhesive mat 63 with the release sheet in close contact with the side surface S3, the adhesive mat 63 is slid downward along the side surface S3 to attach the adhesive mat 62 to the floor surface S2, and the second substrate 20 is attached to the floor surface.

Next, the two bolts 50 inserted into the second extension portion 22 and the second split extension portion 42 are temporarily tightened by loosening them, and the adhesive mat 63 with the release sheet and the side surface S3 are in close contact with each other. Weaken. After that, the release sheet is peeled off from the adhesive mat 63, the second divided substrate 40 is pressed toward the side surface S3, and the adhesive mat 63 is attached to the side surface S3. By fully tightening the two bolts 50 inserted into the second extension portion 22 and the second split extension portion 42, the adhesive mat 63 is attached to the side surface S3 in a compressed state. At this time, the tightness of the two bolts 50 inserted into the second extension portion 22 and the second split extension portion 42 is such that the adhesive mat 63 has an appropriate amount of compression. The appropriate compression amount is, for example, a compression amount such that the adhesive mat 63 does not protrude from the outer edge of the second divided substrate 40.

As shown in FIGS. 1 and 7, the second substrate 20 and the floor surface S2 are fixed by the adhesive mat 62, the second divided substrate 40 is fixed to the side surface S3 by the adhesive mat 63, and the first divided plate portion 33 is fixed. Consider a state in which the first split base 30 and the second base 20 are temporarily tightened by loosening the two bolts 50 inserted through the second split extension portion 42.

Next, in this state, the boundary portion B is pushed up by the tool T, an insertion space Sp is formed between the first divided main body portion 31 and the second main body portion 21, and the tool T is inserted into the insertion space Sp. The tool T is, for example, a rod-shaped tool such as a screwdriver.

Even if the first split main body 31 is close to the second main body 21, the bulging portion 37 comes into contact with the first surface 21a of the second main body 21, so that the first base 10 and the second base 20 It is separated from each other and can function as a space for inserting the tool T. Further, the boundary portion B projects slightly outward from the first long edge of the second main body portion 21. Therefore, in a state where the second substrate 20 is fixed to the floor surface S2, a gap is formed between the boundary portion B and the floor surface S2. The gap can be a trigger for inserting the tool T between the first split main body 31 and the second main body 21. Further, since the boundary portion B has a smooth surface forming an arc, the tool T can be inserted into the gap without the tip of the tool T being caught by the boundary portion B.

Next, the tool T is rotated in a direction away from the second main body portion 21 with the projecting portion 26 as a fulcrum. At this time, the tool T comes into contact with the boundary portion B between the first split main body portion 31 and the first split extension portion 32, and pushes up the first split base 30 in a direction away from the second base 20. The projecting portion 26 is a fulcrum forming portion that the tool T comes into contact with and serves as a fulcrum. The boundary portion B is a pressed portion that is provided at a position facing the floor surface S2 and becomes an action point when the tool T comes into contact with the tool T in a state of being in contact with the projecting portion 26. In this case, the second substrate 20 is a fulcrum substrate, and the first substrate 10 is a pressed substrate.

When the first split base 30 is pushed up by the tool T, the adhesive mat 61 provided on the first split base 30 comes into contact with the bottom surface S1 of the installation body 100 and is joined. The adhesive mat 61 is joined to the bottom surface S1 in a state where the tool T in contact with the projecting portion 26 is tilted, the boundary portion B is pressed, and the adhesive mat 61 is compressed. Further, since the tip of the tool T is pressed against the second substrate 20, the adhesive mat 62 is joined to the floor surface S2 in a compressed state in the thickness direction.

Next, the first split extension portion 32 is pushed up by the tool T, the adhesive mat 61 is pressed against the bottom surface S1, and the adhesive mat 62 is pressed against the floor surface S2 to be compressed in the thickness direction. By finally tightening the two bolts 50 inserted through the second split extension portion 42, the first base 10 and the second base 20 are assembled so as to be relatively immovable. In the present embodiment, the main assembly of the first base 10 and the second base 20 is realized by fastening the bolt 50 whose screwing direction is the insertion direction of the tool T, and the first base 10 and the second base 20 Temporary assembly is realized by loosening the bolt 50 in the insertion direction of the tool T. As a result, the installation body 100 is fixed to the floor surface S2 by the fixed body 1.

The effect of this embodiment will be described.
(1) In the present embodiment, the second substrate 20 is a fulcrum substrate, and the first substrate 10 is a pressed substrate. When the tool T is rotated so that the projecting portion 26 is a fulcrum and the boundary portion B is an action point, the first substrate 10 is pressed by the tool T toward the bottom surface S1, and the adhesive mat 61 is pressed against the bottom surface S1. Is pressed against. Further, when the tool T is further rotated while the boundary portion B is pressed toward the bottom surface S1, the second substrate 20 is also pressed toward the floor surface S2, and the adhesive mat 62 is pressed against the floor surface S2. Be done. That is, the adhesive mat 61 can be firmly bonded to the bottom surface S1 and the adhesive mat 62 can be firmly bonded to the floor surface S2 by the principle of using the tool T. Therefore, the adhesive mats 61 and 62 can be firmly joined to the bottom surface S1 and the floor surface S2.

(2) Since the projecting portion 26 is composed of a convex step portion, the tip of the tool T can be easily pressed. Since the tip of the tool T is less likely to slip when the tool T is rotated, the tool T can be operated stably.

(3) Since the front side of the first surface 21a in the insertion direction of the tool T forms a flat surface, the tip of the tool T can be brought into contact with the projecting portion 26 without interfering with the insertion of the tool T.

(4) When the first base 10 and the second base 20 are relatively moved, they are located near the short edges of the pair of second protrusions 24, the pair of first split protrusions 34, and the second split main body 41. The second split protrusion 44 can guide the first base 10 and the second base 20 so that the direction in which the first base 10 and the second base 20 move relative to each other is the facing direction A. Therefore, it becomes easier to press the adhesive mat 61 toward the bottom surface S1 and the adhesive mat 62 toward the floor surface S2 by the tool T.

(5) Since the tip of the tool T is brought into contact with the projecting portion 26, it is not necessary to support the tool T only by the operator. That is, it is possible to easily maintain the first divided substrate 30 of the first substrate 10 in a pushed-up state. Therefore, it is possible to easily maintain the state in which the first substrate 10 is pulled up from the second substrate 20. As a result, the first base 10 and the second base 20 can be easily assembled with a plurality of bolts 50, so that the fixing workability between the first base 10 and the second base 20 is also improved.

(6) The second protruding portion 24, the first divided protruding portion 34, and the second divided protruding portion 44 serve as reinforcing portions for suppressing distortion of the first substrate 10 and the second substrate 20 having a metal plate shape. Can be made to work.

(7) Since the first base 10 and the second base 20 are reinforced by the second protruding portion 24, the first split protruding portion 34, and the second split protruding portion 44, for example, the first base 10 and the second base. 20 can be made thinner, and the weight of the fixed body 1 can be reduced. As a result, the transportability and workability of the fixed body 1 are improved.

(8) The second protrusion 24, the first split protrusion 34, and the second split protrusion 44 have a function of guiding the relative movement between the first base 10 and the second base 20, and the first base 10 and the first. 2 It also has a function of reinforcing the substrate 20. Therefore, it is not necessary to separately provide the structure having the function of guiding and the structure having the function of reinforcing the fixed body 1.

(9) The contact portion 46 facilitates relative movement between the first substrate 10 and the second substrate 20. Therefore, the position adjustment work of the first base 10 and the second base 20 becomes simple. Further, once the positional relationship between the first base 10 and the second base 20 is determined, the first base 10 and the second base 20 are fixed so as not to be relatively movable only by fully tightening the bolt 50. Therefore, the positioning work of the first base 10 and the second base 20 becomes simple.

(10) The second protrusion 24, the first split protrusion 34, and the second split protrusion 44 can be formed only by bending the same member. Therefore, the direction in which the first substrate 10 and the second substrate 20 move relative to each other can be determined by a simple configuration.

(11) In the fixed structure of the present embodiment, the fixed body 1 has a configuration in which the direction in which the first base 10 and the second base 20 move relative to each other is limited to one direction. Since one direction is the facing direction A, the first divided main body portion 31 is less likely to be displaced with respect to the bottom surface S1, and the second substrate 20 is less likely to be displaced with respect to the floor surface S2. Therefore, the first substrate 10 is difficult to detach from the bottom surface S1, and the second substrate 20 is difficult to detach from the floor surface S2, so that the installation body 100 can be stably fixed to the floor surface S2.

In addition, this embodiment can be implemented by changing as follows. The present embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.
