The adhesive fixture 11 includes a pair of fixing parts 12, a bolt-like member 21 protruding from each fixing part 12, and a connecting member 30 into which the bolt-like members 21 protruding from the pair of fixing parts 12 are screwed together. .

The adhesive mat 20 has a plate shape having adhesive surfaces on both sides in the thickness direction. The adhesive mat 20 can be compressed and deformed in the thickness direction. The adhesive mat 20 is made of gel-like ultra-soft urethane with adhesive properties. Further, the adhesive mat 20 exhibits optimum adhesive strength by being compressed to a thickness of 50% to 90% of the thickness before compression. The adhesive mat 20 has a first surface 20a in the thickness direction attached to the fixing part 12, and a second surface 20b in the thickness direction attached to the lower surface 10a of the object to be fixed 10 or the upper surface Fa of the floor F. Ru.

As shown in FIG. 4 or 6, the bolt-like member 21 is a bolt having a hexagonal columnar head 22 and a shaft portion 23 protruding from the head 22. In a plan view of the head 22 viewed along the axial direction of the bolt-like member 21, the head 22 has a hexagonal shape. The head 22 includes a head end surface 22a that is hexagonal in plan view and six side surfaces 22b that intersect the head end surface 22a. A male thread is formed on the outer peripheral surface of the shaft portion 23.

Next, the fixing portion 12 will be explained. Note that the adhesive fixture 11 includes a pair of fixing parts 12, but since the pair of fixing parts 12 have the same configuration, one fixing part 12 will be explained, and a description of the other fixing part 12 will be omitted.

As shown in FIGS. 3 to 6, the fixing part 12 includes a fixing part main body 13 made of a metal plate, a plurality of protrusions 17 protruding from the periphery of the fixing part main body 13, and a plurality of protrusions 17 that are attached to the fixing part main body 13. An adhesive mat 20 is provided.

The fixing part main body 13 has a square plate shape. The fixing part main body 13 includes a mat adhesion surface 13a on one surface in the thickness direction, and a back surface 13b on the other surface in the thickness direction. The mat sticking surface 13a has a larger area than the adhesive mat 20. Further, the shape of the mat adhering surface 13a matches the rectangular shape that is the shape of the first surface 20a of the adhesive mat 20. An adhesive mat 20 is attached to the mat attachment surface 13a of the fixing portion main body 13.

The fixing portion 12 has a bulging portion 14 that bulges out toward the connecting member 30 from the back surface 13b of the fixing portion main body 13. The bulging portion 14 has a circumferential wall 15 that protrudes into a cylindrical shape, and an annular bottom portion 16 located at the tip of the circumferential wall 15 in the protruding direction. The annular bottom 16 is located at the top of the bulge 14 .

In a plan view of the fixing portion main body 13 along a direction orthogonal to the mat adhesion surface 13a, the peripheral wall 15 has a track shape. The inner surface of the peripheral wall 15 has a pair of restricting surfaces 15a facing each other in the surface direction along the mat sticking surface 13a, and a pair of arcuate surfaces 15b connecting the ends of the pair of restricting surfaces 15a.

As shown in FIG. 5 or 6, the fixing part 12 has a through hole 16a that penetrates the annular bottom part 16. The through hole 16a passes through the annular bottom portion 16 in the thickness direction of the fixing portion main body 13. The through hole 16a is formed at the top of the bulging portion 14 that bulges toward the back surface 13b of the fixing portion main body 13. The depth D of the bulging portion 14 is defined as the dimension from the mat attachment surface 13a of the fixing portion main body 13 in the plate thickness direction to the annular bottom portion 16.

A bolt-like member 21 is inserted through the bulge 14 . The head 22 of the bolt-like member 21 is accommodated in the head accommodating portion 14c. Further, in the head 22, the protruding end surface of the shaft 23 is in contact with the annular bottom 16, which is the top of the bulge 14. The dimension of the head 22 of the bolt-like member 21 in the axial direction is defined as a head length L. In this embodiment, the depth D of the bulge 14 is the same as the head length L. Therefore, the head end surface 22a, which is the surface of the head 22 on the mat attachment surface 13a side, is located on the same plane as the mat attachment surface 13a. A head end surface 22a of the head 22 is covered with an adhesive mat 20. Further, a part of the first surface 20a of the adhesive mat 20 faces the head end surface 22a. The head end surface 22a is covered with the adhesive mat 20, and is accommodated in the head accommodating portion 14c while being adhered to the first surface 20a.

The shaft portion 23 of the bolt-like member 21 passes through the annular bottom portion 16 . Therefore, the shaft portion 23 protrudes toward the back surface 13b side of the fixing portion main body 13. That is, the bolt-like member 21 is inserted into the through hole 16a that penetrates the fixing part main body 13 in the thickness direction so that the tip of the shaft part 23 projects toward the back surface 13b. A nut 24 is screwed onto the shaft portion 23 . The annular bottom portion 16 is sandwiched between the nut 24 and the head portion 22, and a bolt-like member 21 is integrated into the fixing portion main body 13. As a result, the fixing portion 12 and the bolt-like member 21 are integrated.

Among the six side surfaces of the head 22, the distance between two mutually parallel side surfaces 22b is defined as the width across flats W of the head 22. The width across flats W is slightly shorter than the distance between the regulating surfaces 15a of the peripheral wall 15. The head 22 is housed inside the peripheral wall 15 that is inside the bulge 14 . Two parallel side surfaces 22b of the head 22 are arranged to face the restriction surface 15a, and rotation of the bolt-like member 21 is restricted by contact between the restriction surface 15a and the head 22.

As shown in FIG. 3, FIG. 5, or FIG. 6, the protruding portion 17 has a ridge shape that extends longitudinally along the edge of the fixing portion main body 13. As shown in FIG. Two protrusions 17 are provided on each of the four side edges 13d forming the peripheral edge of the fixing part main body 13. The protrusions 17 are arranged near both ends of each side edge 13d. The two protrusions 17 provided on each side edge 13d are arranged at intervals in the direction in which the side edge 13d extends. A recess 18 is formed between adjacent protrusions 17 on each side edge 13d.

Moreover, each protrusion 17 is located at a position slightly shifted toward the center from the end of each side edge 13d. At each corner of the fixing part main body 13, the protruding parts 17 of the intersecting side edges 13d are spaced apart from each other, and a gap S is formed between adjacent protruding parts 17 at each corner of the fixing part main body 13. There is.

In a plan view of the fixing part 12 viewed from the outside along a direction perpendicular to the mat sticking surface 13a, the plurality of protrusions 17 are arranged so as to surround the adhesive mat 20. Here, when an imaginary line M is assumed to pass through all the protrusions 17 in plan view, this imaginary line M is a quadrilateral. The proportion of all the protrusions 17 in the virtual line M is larger than the proportion of the recesses 18.

Each protrusion 17 includes an inner surface 17b facing the periphery of the adhesive mat 20. Note that the inner surface 17b is a surface that is continuous with the mat attachment surface 13a and is a surface that intersects with the mat attachment surface 13a. The protruding portion 17 is inclined outward from the fixing portion main body 13 such that the angle between the inner surface 17b and the mat sticking surface 13a is greater than 90 degrees.

The protruding portion 17 protrudes from the fixing portion main body 13 toward the second surface 20b of the adhesive mat 20. The dimension from the mat sticking surface 13a to the tip edge 19a of the protrusion 17 is defined as the height dimension of the protrusion 17. The height of the protrusion 17 is smaller than the thickness of the adhesive mat 20 in an uncompressed state. Therefore, the entire protrusion 17 is located at a position closer to the first surface 20a than the second surface 20b of the adhesive mat 20.

As shown by the two-dot chain line in FIG. 5, the protruding portion 17 has convex pieces 17a that protrude in a rectangular shape from each side edge 13d of the fixing portion main body 13 along the surface direction of the mat adhering surface 13a. It is formed by bending toward the surface 13a. In other words, it can be said that the protruding portion 17 is formed by bending the periphery of the fixing portion main body 13. Before the protruding portion 17 is bent and formed, the protruding piece 17a protrudes from the periphery of the fixing portion main body 13 along the surface direction of the fixing portion main body 13. In the convex piece 17a, an end face 17d located at the tip of the protruding direction from the peripheral edge of the fixing part main body 13 is a flat face perpendicular to the mat sticking surface 13a.

The protruding portion 17 is formed by bending the protruding piece 17a toward the mat attachment surface 13a using the side edge 13d of the fixing portion main body 13 as a bending starting point. The protrusion 17 is formed by bending the protrusion 17a, and as described above, the bending angle of the protrusion 17a is adjusted so that the angle between the inner surface 17b of the protrusion 17 and the mat attachment surface 13a is greater than 90 degrees. By adjusting , the end surface 17d of the convex piece 17a is inclined.

Each of the protruding parts 17 has an inclined surface 19 at the tip thereof protruding from the fixing part main body 13 toward the second surface 20b of the adhesive mat 20. The inclined surface 19 is inclined toward the first surface 20a from the second surface 20b of the adhesive mat 20 as it moves away from the adhesive mat 20 along the surface direction of the fixing part main body 13 and the adhesive mat 20. As described above, since the inner surface 17b of the protruding portion 17 formed by bending the protruding piece 17a is inclined with respect to the mat attachment surface 13a, the end face 17d located at the tip of the protruding piece 17a in the protruding direction is also inclined. , an inclined surface 19 is formed by this inclined end surface 17d. Note that the protrusion 17 includes a tip edge 19a at the intersection of the inner surface 17b and the inclined surface 19. The tip edge 19a extends linearly along the side edge 13d, and the intersection of the protrusions 17 has an edge shape.

Among the angles between the virtual plane C1 passing through the mat sticking surface 13a and the virtual plane C2 passing through the inclined surface 19, the smaller angle is defined as the inclination angle θ of the inclined surface 19. It is preferable that the inclination angle θ is set to be greater than 0 degrees and less than 45 degrees. This is because if the inclination angle θ is larger than 45 degrees, when the fixing portion 12 is inclined due to earthquake shaking, the inclined surface 19 becomes difficult to come into surface contact with the surface to be adhered.

Further, the above-mentioned recess 18 is provided closer to the mat attachment surface 13a than the inclined surface 19. Note that the recess 18 extends from the inclined surface 19 to the mat attachment surface 13a.
As shown in FIG. 3 or 4, the fixing part 12 includes a bead 12a that protrudes from the mat attachment surface 13a of the fixing part main body 13 toward the back surface 13b. The bead 12a reinforces the fixing part main body 13. The bead 12a is formed by recessing the fixing part main body 13 from the mat sticking surface 13a, and is formed by making the fixing part main body 13 protrude on the opposite side from the mat sticking surface 13a.

The bead 12a extends straight from the center of the fixing part main body 13 toward the four corners of the fixing part main body 13. Note that the shape of the bead 12a and the position in the fixing portion main body 13 may be changed as appropriate. A gap J is formed between the first surface 20a of the adhesive mat 20 and the mat sticking surface 13a by the bead 12a. The gap J extends straight from the center of the fixing part main body 13 toward the four corners of the fixing part main body 13. Further, the gap J is recessed from the mat attachment surface 13a of the fixing portion main body 13. In other words, the gap J is formed by a bead 12a that is a part of the mat attachment surface 13a bulging toward the back surface 13b.

Next, the connecting member 30 will be explained. The connecting member 30 connects the two fixing parts 12 with the end surfaces of the shaft parts 23 of the bolt-like members 21 integrated with the fixing parts 12 facing each other. Note that the male threads of the two bolt-like members 21 are in a reverse thread relationship with each other.

The connecting member 30 has a hexagonal cylindrical shape with a female threaded hole 30a on the inner peripheral surface. The female screw hole 30a passes through the connecting member 30 in the axial direction. A shaft portion 23 protruding from one fixing portion 12 is screwed into a first end of the female threaded hole 30a in the axial direction, and a shaft portion 23 protruding from the other fixing portion 12 is screwed into a second end of the female threaded hole 30a in the axial direction. A protruding shaft portion 23 is screwed together. That is, the two fixing parts 12 are connected by the bolt-like member 21 and the connecting member 30.

For example, the connecting member 30 is rotated so that the connecting member 30 is separated from one of the fixed portion main bodies 13. At this time, when the other shaft portion 23 is rotated together with the connecting member 30, the other fixed portion main body 13 can be moved by the same amount as the moving distance of the connecting member 30.

Further, when the connecting member 30 is rotated so that the connecting member 30 is separated from one of the fixing portion main bodies 13, only the connecting member 30 is rotated without rotating the other shaft portion 23. Then, both shaft portions 23 are separated from the connecting member 30, and the other fixed portion main body 13 can be moved by an amount greater than the moving distance of the connecting member 30.

As described above, by operating the connecting member 30, the distance between the two fixing portion main bodies 13 along the axial direction of the connecting member 30 can be adjusted. Since the adhesive mats 20 are attached to each fixing part main body 13, the distance between the two adhesive mats 20 along the axial direction of the connecting members 30 can be adjusted by operating the connecting members 30.

Next, the installation structure of the adhesive fixture 11 will be explained. Of the two fixing parts 12 of the adhesive fixture 11, the lower fixing part 12 is a first fixing part 121, and the upper fixing part 12 is a second fixing part 122.

As shown in FIG. 1 or 4, in the installation structure of the adhesive fixture 11, the second surface 20b of the adhesive mat 20 of the first fixing part 121 is stuck to the upper surface Fa of the floor F, and The second surface 20b of the adhesive mat 20 is adhered to the lower surface 10a of the object to be fixed 10. In addition, in the installation structure of the adhesive fixture 11, the adhesive mat 20 of the first fixing part 121 can exert a desired adhesive force between the mat sticking surface 13a of the first fixing part 121 and the upper surface Fa of the floor F. It is compressed and deformed in the thickness direction.

Similarly, the adhesive mat 20 of the second fixing part 122 is arranged in the thickness direction so that the desired adhesive force can be exerted between the mat sticking surface 13a of the second fixing part 122 and the lower surface 10a of the object to be fixed 10. It has been compressed and deformed. In this embodiment, the adhesive mat 20 is compressed to a thickness that is 50% to 90% of the thickness before compression.

Note that the head 22 of the bolt-like member 21 does not protrude from the mat attachment surface 13a of the fixing portion main body 13, and the mat attachment surface 13a and the head end surface 22a are located on the same plane. Therefore, the amount of compression of the adhesive mat 20 is the same at any position in the surface direction. The head end surface 22a of the head 22 is adhered to the first surface 20a of the adhesive mat 20.

In the installation structure of the adhesive fixture 11, the protruding portion 17 of the first fixing portion 121 has an inclined surface 19 including a tip edge 19a separated from the upper surface Fa of the floor F. At this time, the inclined surface 19 has a dimension smaller than the thickness of the compressively deformed adhesive mat 20 and is spaced apart from the upper surface Fa.

Further, in the protruding portion 17 of the second fixing portion 122, the inclined surface 19 including the tip edge 19a is separated from the lower surface 10a of the fixing object 10. At this time, the inclined surface 19 has a dimension smaller than the thickness of the compressively deformed adhesive mat 20 and is spaced apart from the lower surface 10a.

In other words, in the state before the installation structure of the adhesive fixture 11 is constructed, the inclined surface 19 is held back from the second surface 20b of the adhesive mat 20, so that even after the installation structure is constructed, the inclined surface 19 and each surface 10a, Fa is separated. By utilizing this separation, the adhesive mat 20 can be compressed and deformed between the mat sticking surface 13a and each surface 10a, Fa.

In the first fixing part 121, the periphery of the adhesive mat 20 is exposed between the tip edge 19a of the inclined surface 19 and the upper surface Fa of the floor F, and from the recess 18, and in the second fixing part 122, the periphery of the adhesive mat 20 The peripheral edges are exposed between the tip edge 19a of the inclined surface 19 and the lower surface 10a of the fixed object 10, and from the recess 18, respectively.

Next, a method for installing the adhesive fixture 11 will be explained.
First, in the adhesive fixture 11, the distance between the second surfaces 20b of the two adhesive mats 20 along the axial direction of the connecting member 30 is determined from the distance between the lower surface 10a of the object to be fixed 10 and the upper surface Fa of the floor F. shorten.

Next, on the upper surface Fa of the floor F, the adhesive fixture 11 is arranged below the lower surface 10a of the object to be fixed 10, and the adhesive mat 20 of the first fixing part 121 is placed on the upper surface Fa. Then, the connecting member 30 is rotated to bring the second fixing section 122 closer to the object to be fixed 10, and the second surface 20b of the adhesive mat 20 of the second fixing section 122 is stuck to the lower surface 10a of the object to be fixed 10. . Furthermore, the connecting member 30 is rotated to bring the second fixing part 122 closer to the fixing target 10. Then, the adhesive mat 20 of the first fixing part 121 and the adhesive mat 20 of the second fixing part 122 are compressed and deformed. At this time, the amount of rotation of the connecting member 30 is adjusted so that the adhesive mat 20 is compressed and deformed until the thickness becomes 50% to 90% of the thickness before compression.

Further, the amount of rotation of the connecting member 30 is adjusted so that the protruding part 17 of the first fixing part 121 is separated from the upper surface Fa of the floor F, and the protruding part 17 of the second fixing part 122 is separated from the lower surface 10a of the fixed object 10. Adjust.

Then, the second surface 20b of the adhesive mat 20 of the first fixing part 121 is attached to the upper surface Fa of the floor F, and the second surface 20b of the adhesive mat 20 of the second fixing part 122 is attached to the lower surface of the object to be fixed 10. 10a. As a result, the object to be fixed 10 is fixed to the floor F by the adhesive fixture 11.

In the installation structure of the adhesive fixture 11, there may be a case where the fixing part main body 13 is peeled off from the adhesive mat 20. At this time, it is preferable to inject a release agent into the gap J provided in the bead 12a of the fixing part main body 13. Then, the tip of the crowbar-shaped tool is inserted into the recess 18, and the tool is scooped out with the tip of the tool directed toward the mat attachment surface 13a. Then, the fixing portion main body 13 can be peeled off from the adhesive mat 20.

Next, the operation of the adhesive fixture 11 and its installation structure will be explained.
Now, when an earthquake occurs, the floor F shakes and the fixed object 10 shakes due to the shaking caused by the earthquake. Then, due to the shaking, a load is applied to some parts of the adhesive mat 20, and some parts are further compressed and deformed.

As shown in FIG. 7, when the adhesive mat 20 is further compressed, in the first fixed portion 121, almost the entire slope 19 of the protrusion 17 near the compressed portion comes into contact with the upper surface Fa of the floor F. Due to the partial compression of the adhesive mat 20, the first fixing portion 121 is inclined, so that the inclined surface 19 comes into surface contact with the upper surface Fa of the floor F. Also in the second fixing part 122, the inclined surface 19 of the protrusion part 17 near the compressed part contacts the lower surface 10a of the fixing object 10.

Further, when the adhesive mat 20 is compressed in the entire thickness direction, the tip edge 19a of the protrusion 17 comes into contact with the lower surface 10a of the object to be fixed 10 and the upper surface Fa of the floor F. In this embodiment, the tip edges 19a of the plurality of protrusions 17 contact each surface 10a, Fa.

According to the above embodiment, the following effects can be obtained.
(1) When an earthquake occurs and the fixed part 12 is tilted due to partial compression of the adhesive mat 20, almost the entire surface of the inclined surface 19 comes into surface contact with the lower surface 10a of the fixed object 10 and the upper surface Fa of the floor F. . Surface contact between the inclined surface 19 and each surface 10a, Fa suppresses displacement of the fixed portion 12 in the direction along each surface 10a, Fa, and prevents the adhesive mat 20 from peeling off due to shaking.

(2) The fixing part 12 is made of a metal plate, and the protruding part 17 is formed by bending the peripheral edge (projection piece 17a) of the fixing part main body 13. Before the protruding piece 17a is bent, the protruding piece 17a protrudes from each side edge 13d of the fixing portion main body 13 in the surface direction. When bending the protruding piece 17a, by adjusting the bending angle of the protruding piece 17a, the entire protruding portion 17 is inclined with respect to the mat adhesion surface 13a. Therefore, the inclined surface 19 can be formed by the end surface 17d located at the tip of the convex piece 17a, and the protrusion 17 having the inclined surface 19 can be easily formed.

(3) When the adhesive mat 20 is compressed over the entire surface direction, the tip edges 19a of the plurality of protrusions 17 come into contact with the lower surface 10a of the object to be fixed 10 and the upper surface Fa of the floor F. The frictional resistance caused by the contact of the tip edge 19a of the protrusion 17 with each surface 10a, Fa suppresses the displacement of the fixing portion 12 in the direction along each surface 10a, Fa, and prevents the adhesive mat 20 from sticking due to shaking. It can suppress the decrease in power.

(4) In this embodiment, the tip edges 19a of the plurality of protrusions 17 simultaneously contact each surface 10a, Fa. Therefore, the frictional resistance caused by the contact of the distal end edge 19a of the protruding portion 17 with each surface 10a, Fa can be increased, and the displacement of the fixing portion 12 in the direction along each surface 10a, Fa can be suppressed. In addition, since the protruding portion 17 has an edge shape, the distal end edge 19a bites into each surface 10a, Fa, thereby suppressing the displacement of the fixed portion 12 in the direction along each surface 10a, Fa. Decrease in the adhesive strength of the adhesive mat 20 can be suppressed.

(5) The protruding portion 17 has a ridge shape. For example, compared to the case where the protrusion 17 is pin-shaped, the contact area of the protrusion 17 with each surface 10a, Fa can be increased. Therefore, the shaking of the fixing portion 12 in the plane direction is restricted, and a decrease in adhesive strength due to the shaking can be suppressed.

(6) The plurality of protrusions 17 are arranged along the periphery of the adhesive mat 20, and recesses 18 are formed between adjacent protrusions 17 in the direction in which the periphery of the adhesive mat 20 extends. Although the protrusion 17 faces a part of the periphery of the adhesive mat 20, the part provided with the recess 18 is exposed to the outside. If it is necessary to peel off the fixing part main body 13 from the adhesive mat 20, a tool can be inserted through the recess 18. Therefore, it becomes easier to peel off the fixing part main body 13 from the adhesive mat 20 using a tool.

(7) In a plan view of the fixing part 12, the plurality of protrusions 17 are arranged so as to surround the adhesive mat 20. Then, assuming an imaginary line M passing through a plurality of protrusions 17 in a plan view, the proportion of all the protrusions 17 in the imaginary line M is larger than the proportion of the recesses 18. For this reason, when an earthquake occurs and the fixing part main body 13 is tilted, the contact area of the inclined surface 19 and the tip edge 19a with each surface 10a, Fa can be increased.

(8) A gap J is ensured between the mat sticking surface 13a of the fixing part main body 13 and the first surface 20a of the adhesive mat 20. By injecting a release agent into this gap J, it becomes easier to separate the fixing part main body 13 from the adhesive mat 20.

(9) A bead 12a is provided on the fixing part main body 13 to reinforce the fixing part main body 13, and the inside of this bead 12a can be used as a gap J for injecting a release agent. Therefore, manufacturing of the fixing part 12 becomes easier compared to the case where the bead 12a and the part for injecting the release agent are separately molded on the fixing part main body 13.

(10) The fixing portion main body 13 includes the bulge portion 14. The head 22 of the bolt-like member 21 can be accommodated inside the peripheral wall 15 while the head 22 of the bolt-like member 21 is brought into contact with the annular bottom 16 of the bulging portion 14 . Therefore, compared to the case where the head 22 is brought into direct contact with the mat sticking surface 13a, the amount of protrusion of the head 22 from the mat sticking surface 13a can be reduced. Therefore, in order to prevent the head end surface 22a from protruding from the second surface 20b of the adhesive mat 20, it is no longer necessary to form a hole in the adhesive mat 20 through which the head 22 passes, and the area of the adhesive surface of the adhesive mat 20 is reduced. No need to decrease. As a result, it is possible to eliminate a decrease in adhesive strength due to a decrease in the area of the adhesive surface of the adhesive mat 20.

(11) The depth D of the bulge 14 was made the same as the head length L of the head 22. Therefore, when the head 22 of the bolt-like member 21 is in contact with the annular bottom 16 of the bulging part 14, the head end surface 22a of the head 22 is in the same plane as the mat attachment surface 13a of the fixing part main body 13. can be placed above. As a result, even when the adhesive mat 20 is compressed and deformed, there is almost no bias in the amount of compression at any position in the surface direction, and a constant adhesive force can be exerted.

(12) The circumferential wall 15 of the bulging portion 14 includes a regulating surface 15a, and the width across flats W of the head 22 is slightly shorter than the distance between the regulating surfaces 15a of the circumferential wall 15. The side surface 22b of the head 22 is arranged to face the regulating surface 15a, and the rotation of the bolt-like member 21 can be regulated by contact between the regulating surface 15a and the side surface 22b.

(13) In the installation structure of the adhesive fixture 11, the amount of rotation of the connecting member 30 is adjusted so that the thickness of the adhesive mat 20 is 50 to 90% of the thickness before compression, and each surface 10a , Fa is adjusted. Therefore, material destruction due to excessive compression of the adhesive mat 20 can be avoided, and a decrease in adhesive strength can be suppressed. Furthermore, it is possible to avoid weakening of the tensioning force of the adhesive fixture 11 due to the adhesive mat 20 not being compressed, and to suppress the deterioration of the fixing function of the adhesive fixture 11. In addition, in the event of an earthquake, the adhesive mat 20 is compressed and the inclined surface 19 immediately comes into surface contact with the lower surface 10a of the fixed object 10 and the upper surface Fa of the floor F, thereby suppressing excessive compression of the adhesive mat 20 due to earthquake shaking. can.

(14) The inclination angle θ of the inclined surface 19 was set to 45 degrees or less. Therefore, when the fixed part 12 is tilted due to earthquake shaking, the inclined surface 19 is easily brought into surface contact with the lower surface 10a of the fixed object 10 and the upper surface Fa of the floor F.

(15) In the installation structure of the adhesive fixture 11, the adhesive mat 20 is compressed and deformed between the mat attachment surface 13a and each surface 10a, Fa, but the protruding portion 17 is separated from each surface 10a, Fa. are doing. Therefore, compressive deformation of the adhesive mat 20 due to earthquake shaking is allowed, and further compressive deformation of the adhesive mat 20 can be suppressed by the projections 17 coming into contact with the respective surfaces 10a and Fa. Therefore, the protruding portion 17 can suppress a decrease in adhesive force due to excessive compressive deformation of the adhesive mat 20, and the fixing portion 12 can maintain the state in which the object to be fixed 10 is fixed to the floor F.

This embodiment can be modified and implemented as follows. This embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.
○ As shown in FIG. 8, in an installation structure in which an adhesive fixture 11 is interposed between the object to be fixed 10 and the floor F, and the object to be fixed 10 is fixed to the floor F by the adhesive fixture 11, the adhesive mat 20 is It is attached to the upper surface Fa of the floor F and the lower surface 10a of the fixed object 10. Note that, as the fixing part body 13 moves away from each other due to the rotation of the connecting member 30, the adhesive mat 20 changes in the thickness direction between each surface 10a, Fa and the mat sticking surface 13a of the fixing part body 13. It has been compressed and deformed. In this installation structure, a waterproof member 42 is interposed between the inclined surface 19 of the plurality of protrusions 17 and each surface 10a, Fa. The waterproof member 42 also enters the recess 18 and closes the recess 18. Further, the waterproof member 42 is more easily compressed and deformed under load than the adhesive mat 20.

According to this, the waterproof member 42 can suppress liquid such as moisture from entering between the surfaces 10a, Fa and the inclined surface 19 or from the recess 18 into the inside of the fixing portion 12. Therefore, it is possible to suppress the liquid that acts to peel off the adhesive mat 20 from the mat attachment surface 13a and each surface 10a, Fa from entering into the fixing part 12, thereby suppressing a decrease in the adhesive force of the adhesive mat 20. can.

When an earthquake occurs, when the fixed part 12 is tilted due to partial compression of the adhesive mat 20, the waterproof member 42 is compressed between the slope 19 and each surface 10a, Fa, and the waterproof member 42 is The surface 19 is in surface contact with each of the surfaces 10a and Fa with the waterproof member 42 sandwiched between them. Due to the surface contact between the inclined surface 19 and each surface 10a, Fa with the waterproof member 42 in between, the displacement of the fixed part 12 in the direction along each surface 10a, Fa is suppressed, and the adhesive mat 20 is prevented from peeling off due to shaking. can be suppressed.

In addition, in the installation structure shown in FIG. 8, the waterproof member 42 may not be provided between the inclined surface 19 of the protruding part 17 of the second fixing part 122 and the lower surface 10a of the fixed object 10.
As shown in FIG. 9, the fixing part 12 may include, in addition to the protruding part 17, a protruding part 40 that protrudes from the periphery of the fixing part main body 13. The piercing portion 40 is located between the protruding portions 17 on the side edge 13d. The tip of the piercing portion 40 projects further toward the second surface 20b of the adhesive mat 20 than the inclined surface 19 of the protruding portion 17.

According to this, when an earthquake occurs and the adhesive mat 20 is compressed in the thickness direction, the piercing portions 40 pierce the lower surface 10a of the fixed object 10 as the surface to be adhered and the upper surface Fa of the floor F. . The piercing of the piercing portion 40 restricts the shaking of the fixing portion 12 in the surface direction, and it is possible to suppress a decrease in the adhesive force of the adhesive mat 20 due to the shaking.

○ In a plan view of the fixing part 12 viewed from the outside along a direction perpendicular to the mat attachment surface 13a, the proportion occupied by all the protrusions 17 in the virtual line M may be the same as the proportion occupied by the concave parts 18. , may be small. In short, the dimensions of the protrusions 17 in the direction along the periphery of the mat attachment surface 13a may be changed, and the size of the recesses 18 between adjacent protrusions 17 may be changed.

○ The protrusion 17 does not have to be in the shape of a protrusion. For example, the protrusions 17 may be formed into a pin shape, and a large number of protrusions 17 may be provided on each side edge 13d of the fixing portion main body 13.
As shown in FIG. 10, the recess 18 does not reach the mat attachment surface 13a, and may be shallower than in the embodiment.

As shown in FIG. 11, the tip edge 19a of the protrusion 17 may be in contact with the lower surface 10a of the object to be fixed 10 or the upper surface Fa of the floor F, which is the surface to be adhered. In this case, as the fixed part main body 13 moves apart due to the rotation of the connecting member 30, the thickness of the adhesive mat 20 increases between the lower surface 10a or upper surface Fa as the surface to be adhered and the mat adhered surface 13a. It is compressed and deformed in the direction.

According to this, the adhesive mat 20 is sandwiched between the mat adhering surface 13a and the adhering surface, and is compressively deformed in the thickness direction. When the adhesive mat 20 is compressed and deformed, the tip edge 19a of the protrusion 17 comes into contact with the surface to be adhered, so that the adhesive mat 20 is prevented from being excessively compressed, and the adhesive force caused by excessive compression is reduced. can suppress the decline in

○ As shown in FIG. 12, in the adhesive fixture 11, the depth D of the bulging portion 14 may be set such that the head end surface 22a of the head 22 protrudes from the mat attachment surface 13a. . In this case, the head length L is greater than the depth D.

When the head end surface 22a protrudes beyond the mat attachment surface 13a, the adhesive mat 20 has a thickness of 50% to 90% of the thickness before compression between the head end surface 22a and each surface 10a, Fa. It has been compressed to the point of being. In this case, in the adhesive mat 20, the region between the head end surface 22a and each surface 10a, Fa is compressed by a larger amount than the region between the mat sticking surface 13a and each surface 10a, Fa. There is.

Even with this configuration, the head 22 of the bolt-like member 21 is accommodated in the head accommodating portion 14c. Therefore, compared to the case where the head 22 is brought into direct contact with the mat sticking surface 13a, the amount of protrusion of the head 22 from the mat sticking surface 13a can be reduced. Therefore, in order to prevent the head end surface 22a of the head 22 from protruding from the second surface 20b of the adhesive mat 20, it is no longer necessary to form a hole in the adhesive mat 20 through which the head 22 passes, and the adhesive mat 20 is not pasted. No reduction in surface area. As a result, it is possible to eliminate a decrease in adhesive strength due to a decrease in the area of the adhesive surface of the adhesive mat 20.

○ As shown in FIG. 13, in the adhesive fixture 11, the depth D of the bulging portion 14 is set so that the head end surface 22a of the head 22 is closer to the back surface 13b than the mat attachment surface 13a. You can leave it there. In this case, the head length L is smaller than the depth D. The depth D and the head length L are such that when the adhesive mat 20 enters the head accommodating portion 14c due to compressive deformation of the adhesive mat 20, the adhesive mat 20 sticks to the head end surface 22a of the head 22. set to be possible.

When the head end surface 22a is located closer to the back surface 13b than the mat adhering surface 13a, the adhesive mat 20 is covered with the relative movement of the fixing part main body 13 due to the rotation of the connecting member 30. The adhesive mat 20, which is compressed and deformed in the thickness direction between the adhesion surface and the mat adhesion surface 13a and has entered the head accommodating portion 14c, is adhered to the head end surface 22a. At this time, between the head end surface 22a and each surface 10a, Fa, the adhesive mat 20 is compressed to a thickness of 50% to 90% of the thickness before compression.

Even with this configuration, the head 22 of the bolt-like member 21 is accommodated in the head accommodating portion 14c. Therefore, compared to the case where the head 22 is brought into direct contact with the mat sticking surface 13a, the amount of protrusion of the head 22 from the mat sticking surface 13a can be reduced. Therefore, in order to prevent the head end surface 22a of the head 22 from protruding from the second surface 20b of the adhesive mat 20, it is no longer necessary to form a hole in the adhesive mat 20 through which the head 22 passes, and the adhesive mat 20 is not pasted. No reduction in surface area. As a result, it is possible to eliminate a decrease in adhesive strength due to a decrease in the area of the adhesive surface of the adhesive mat 20. Further, when the adhesive mat 20 is compressed, the adhesive mat 20 is attached to the head end surface 22a of the bolt-like member 21, so that the area to which the adhesive mat 20 is attached can be increased.

○ As shown in FIG. 14 or 15, a gap forming recess 20c may be provided on the second surface 20b of the adhesive mat 20 in the fixing portion 12. When the second surface 20b of the adhesive mat 20 is attached to the lower surface 10a of the object to be fixed 10 or the upper surface Fa of the floor F, a gap J is formed between the gap forming recess 20c and each surface 10a, Fa. It's okay.

The gap forming recess 20c has a groove shape extending in the surface direction of the second surface 20b. Further, in a plan view seen from a direction perpendicular to the second surface 20b, the gap forming recess 20c extends linearly in the surface direction. Further, in a plan view, the gap forming recess 20c extends to the periphery of the adhesive mat 20, and is open at the periphery of the adhesive mat 20. Note that the shape of the gap-forming recess 20c and the position where the end of the gap-forming recess 20c opens may be changed as appropriate.

In this case, in the adhesive fixture 11, the adhesive mat 20 of the first fixing part 121 is stuck to the upper surface Fa, which is the installation surface of the object 10 to be fixed, and the adhesive mat 20 of the second fixing part 122 is fixed. It is attached to the object 10. Therefore, the adhesive mat 20 of the second fixing part 122 constitutes a fixing object side adhesive mat, and the second fixing part 122 constitutes a fixing subject side fixing part.

By sticking the adhesive fixture 11 to the lower surface 10a of the object to be fixed 10 and the upper surface Fa of the floor F using the adhesive mat 20, there is a first fixing part between the object to be fixed 10 and the floor F. 121 and the second fixing part 122 are constructed.

In the fixing structure of the first fixing part 121, the adhesive mat 20 between the upper surface Fa of the floor F and the mat sticking surface 13a of the first fixing part 121 is compressively deformed with a gap J secured by the gap forming recess 20c. has been done.

When configured in this way, it may be necessary to peel off the adhesive mat 20 from the upper surface Fa of the floor F. At this time, when the release agent is sprinkled on the upper surface Fa of the floor F, the release agent enters the gap J formed by the gap forming recess 20c.

Then, the tip of the crowbar-shaped tool is inserted into the recess 18, the tip of the tool is aimed at the mat sticking surface 13a of the first fixing part 121, and the tool is scooped out. Then, the adhesive mat 20 can be peeled off from the upper surface Fa of the floor F. In particular, if the gap J formed by the gap forming recess 20c is not secured, it is necessary to sprinkle a release agent around the adhesive mat 20 on the upper surface Fa of the floor F and peel it off from around the adhesive mat 20. However, by securing the gap J by the gap forming recess 20c, the release agent can penetrate into the in-plane center of the adhesive mat 20, making it easier to peel off the adhesive mat 20.

○ A plurality of protrusions are provided that protrude from the mat adhesion surface 13a of the fixing part main body 13 toward the adhesive mat 20, and the plurality of protrusions create a gap between the mat adhesion surface 13a and the first surface 20a of the adhesive mat 20. A gap J may also be formed. In this case, the bead 12a may be deleted.

○ A gap forming recess 20c may be formed in the first surface 20a of the adhesive mat 20 to ensure a gap J between the mat sticking surface 13a of the fixing part main body 13 and the first surface 20a of the adhesive mat 20. .

A release agent injection port may be formed in the bead 12a.
In the protrusion 17, the intersection between the inclined surface 19 and the inner surface 17b does not have to have an angular shape like the tip edge 19a, but may have a rounded shape.

The protruding portion 17 does not have to be formed by bending the protruding piece 17a of the fixing part main body 13, but may be formed by, for example, joining the protruding piece 17a to the mat attachment surface 13a by welding.
The fixing part 12 may be made of resin, and in this case, the fixing part main body 13 and the protruding part 17 of the fixing part 12 are integrally molded from resin.

The adhesive mat 20 may have a shape having a hole in which the head 22 of the bolt-like member 21 is accommodated. With this configuration, the holes of the adhesive mat 20 are arranged at positions corresponding to the bulges 14 in a state where the adhesive mat 20 is adhered to the mat attachment surface 13a. When the bolt-like member 21 is integrated with the fixing part 12, the shaft part 23 of the bolt-like member 21 is inserted into the bulging part 14 through the hole of the adhesive mat 20, and the shaft part 23 is passed through the through hole 16a. the head 22 is brought into contact with the annular bottom 16 while Then, a nut 24 is screwed onto the shaft portion 23 to integrate the fixing portion 12 and the bolt-like member 21.

○ The bead 12a of the fixing part main body 13 may be omitted. In this case, no gap J is formed between the adhesive mat 20 and the adhesive mat 20.
Of the pair of fixing parts 12 of the adhesive fixture 11, only one of the fixing parts 12 may be provided with the protruding part 17, and the other fixing part 12 may not be provided with the protruding part 17.

The peripheral wall 15 of the bulging portion 14 has a cylindrical shape and does not need to include the regulating surface 15a.
The circumferential wall 15 may have a hexagonal shape in plan view, and the entire inner surface of the circumferential wall 15 may face the side surface 22b of the head 22 to prevent the head 22 from rotating.

The head 22 may have a polygonal shape other than a hexagonal shape in plan view, and the inner surface of the peripheral wall 15 may have a polygonal shape depending on the shape of the head 22 to form a rotation regulating portion.
○ The bolt-like member 21 was a bolt in which the head 22 and the shaft portion 23 were integrally molded, but the head 22 was made of a nut, the shaft portion 23 was made of a male threaded rod, and the nut was attached to the male threaded rod. The bolt-like member 21 may be formed by screwing together.

The fixing part main body 13 of the fixing part 12 and the bolt-like member 21 may be integrated by welding.
The adhesive fixture 11 may include one fixing part 12, one bolt-shaped member 21 protruding from the fixing part 12, a connecting member 30, and an installation member. In this case, the installation member is installed on the one of the fixing target 10 and the installation part to which the fixing part 12 is not attached. Further, the installation member is not particularly limited to the structure having the fixing part 12 and the bolt-like member 21 as long as it has a male thread that is screwed into the female thread hole 30a of the connecting member 30.

○ The object to be fixed 10 does not need to be fixed to the installation part using the adhesive fixture 11. Specifically, the object to be fixed 10 fixed to the installation part using another fixing tool may be further fixed to the installation part using the adhesive fixing tool 11.

In the embodiment, the fixing part main body 13 does not have to have a square plate shape. For example, the fixing part main body 13 may have a disk shape, a pentagonal plate shape, or a hexagonal plate shape.
○ Instead of a single adhesive mat 20, a plurality of divided adhesive mats 20 may be adhered to the mat attachment surface 13a of the fixing portion main body 13.

The shape of the mat adhesion surface 13a and the shape of the adhesive mat 20 do not need to match; for example, the mat adhesion surface 13a may be square, while the adhesive mat 20 may be oval.

The protruding portion 17 may protrude from a portion other than the peripheral edge of the fixing portion main body 13, for example, may protrude from inside the circumferential edge of the fixing portion main body 13.
Although the inclined surface 19 is formed by inclining the entire protruding portion 17 with respect to the fixing portion main body 13, the present invention is not limited to this. For example, while forming the protrusion 17 by bending the protrusion 17a so that the inner surface 17b of the protrusion 17 is perpendicular to the mat attachment surface 13a, the tip of the protrusion 17a is cut so that the inclination angle is 45 degrees or less. The inclined surface 19 may be formed by, for example,

Alternatively, while forming the protrusion 17 by bending the protrusion 17a so that the angle between the inner surface 17b of the protrusion 17 and the mat attachment surface 13a becomes an acute angle, the tip of the protrusion 17a is tilted at an angle of 45 degrees or less. The inclined surface 19 may be formed by cutting it so that it becomes .
