Examples of the fixed object 10 include a printing device, a multifunction device, furniture, and a television. Examples of the installation part F include the floor, ceiling, desk, etc.

The fixing tool 11 is attached to the lower surface 10a of the object to be fixed 10 and the upper surface Fa of the installation part F using adhesive mats 20, respectively. Therefore, in this embodiment, the lower surface 10a of the object to be fixed 10 and the upper surface Fa of the installation part F constitute a surface to which the adhesive mat 20 is adhered. Further, the lower surface 10a of the fixed object 10 and the upper surface Fa of the installation part F are opposing surfaces facing each other in the vertical direction, one of the opposing surfaces is the upper surface Fa of the installation part F, and the other of the opposing surfaces is the upper surface Fa of the installation part F. The surface is defined as the lower surface 10a.

The fixture 11 includes two fixing members 25 with adhesive mats and a connecting member 30 into which the two fixing members 25 with adhesive mats are screwed together. The fixing member 25 with an adhesive mat includes a fixing portion 12 including an adhesive mat 20 and a bolt-shaped member 21.

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 on one adhesive surface in the thickness direction, and a second surface 20b on the other adhesive surface in the thickness direction. The first surface 20a of the adhesive mat 20 in the thickness direction is attached to the fixing part 12, and the second surface 20b in the thickness direction is attached to the lower surface 10a of the fixed object 10, which is the surface to be attached, or the installation part F. It is attached to the upper surface Fa of.

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.
As shown in FIGS. 1 to 4, 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. The mat sticking surface 13a of the fixing part main body 13 has a square shape that matches the first surface 20a of the adhesive mat 20. The first surface 20a of the adhesive mat 20 is attached to the mat attachment surface 13a.

In this embodiment, the fixing part 12 has a bulging part 14 that bulges out from the back surface 13b of the fixing part main body 13, and a through hole 16a located at the top of the bulging part 14. The bulging portion 14 has a circumferential wall 15 projecting in a cylindrical shape and an annular bottom portion 16 located at the tip in the direction in which the circumferential wall 15 protrudes from the fixing portion main body 13 . The annular bottom 16 is located at the top of the bulge 14 .

As shown in FIG. 6, the peripheral wall 15 has a track shape in a plan view when the fixing portion main body 13 is viewed along a direction orthogonal to the mat sticking surface 13a. 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, 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 sticking surface 13a to the annular bottom portion 16 along the thickness direction of the fixing portion main body 13.

A bolt-like member 21 is inserted into the inside of 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 greater than the head length L. Therefore, the head end surface 22a is located at a position further back than the mat attachment surface 13a.

An adhesive mat 20 is attached to the mat attachment surface 13a of the fixing portion main body 13. The head accommodating portion 14c is covered with an adhesive mat 20, and the head end surface 22a of the head 22 is covered with the adhesive mat 20. The head end surface 22a is located closer to the back surface 13b of the fixing portion main body 13 than the adhesive mat 20 and the mat sticking surface 13a. The position where the head end surface 22a is held back is a position where the adhesive mat 20 that has entered the head accommodating portion 14c can be attached to the head end surface 22a when the adhesive mat 20 is compressed and deformed.

A portion of the first surface 20a of the adhesive mat 20 faces the head end surface 22a of the head 22. The shaft portion 23 of the bolt-like member 21 is inserted into the through hole 16a and 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. The fixing part 12 and the bolt-like member 21 are integrated to form a fixing member 25 with an adhesive mat.

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. The width across flats W is slightly shorter than the distance between the regulating surfaces 15a of the peripheral wall 15. Two mutually parallel side surfaces 22b of the head 22 are arranged opposite to the regulating surface 15a, and the rotation of the bolt-like member 21 is regulated by contact between the opposing regulating surface 15a and the side surface 22b. Therefore, the restriction surface 15a constitutes a rotation restriction portion that prevents the head 22 from rotating by contacting the side surface 22b of the head 22.

As shown in FIG. 2 or 5, 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 of the fixing part main body 13. The protrusions 17 are arranged apart toward both ends of each side edge 13d. A recess 18 is formed between adjacent protrusions 17 on each side edge 13d.

Further, each protrusion 17 is located at a position shifted toward the center from the end of each side edge 13d. Therefore, at the four corners of the fixing part main body 13, the protrusions 17 of the intersecting side edges 13d are spaced apart from each other, and a gap S is formed between the adjacent protrusions 17 at each corner of the fixing part main body 13. has been done.

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 entire protrusion 17 is inclined outward from the fixing part body 13 so that the angle between the inner surface 17b and the mat attachment surface 13a is greater than 90 degrees. Therefore, although the tip surface of the protrusion 17 is a flat surface, the tip surface of the protrusion 17 is inclined due to the inclination of the entire protrusion 17.

Each protrusion 17 has an inclined surface 19 at its tip that protrudes 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 as it moves away from the adhesive mat 20 along the surface direction of the fixing part main body 13.

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. 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.

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. 2 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.
As shown in FIG. 3 or 4, the connecting member 30 connects the shaft portions 23 of the bolt-like members 21 of the two fixing members 25 with adhesive mats in such a manner that the ends of the shaft portions 23 are opposed to each other. That is, the connecting member 30 connects the two fixing members 25 with adhesive mats in a state where the tip surfaces of the shaft portions 23 of the bolt-like members 21 that the two fixing members 25 with adhesive mats have are 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. The bolt-shaped member 21 of one of the fixing members 25 with an adhesive mat is screwed into the first end in the axial direction of the female screw hole 30a, and the other adhesive mat is screwed into the second end in the axial direction of the female screw hole 30a. The bolt-like member 21 of the attached fixing member 25 is screwed together.

The connecting member 30 is rotated so that the connecting member 30 is separated from one of the fixing members 25 with the adhesive mat. At this time, if the other fixing member 25 with an adhesive mat is rotated together with the connecting member 30, the other fixing member 25 with an adhesive mat 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 members 25 with an adhesive mat, the shaft portion 23 of the other fixing member 25 with an adhesive mat is not rotated, and the connecting member 30 Rotate the chisel. Then, both shaft parts 23 are separated from the connecting member 30, and the other fixing member 25 with an adhesive mat 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 members 25 with adhesive mats along the axial direction of the connecting member 30 can be adjusted. Since the adhesive mat 20 is attached to the fixing part main body 13 of each fixing member 25 with an adhesive mat, by operating the connecting member 30, the distance between the two adhesive mats 20 along the axial direction of the connecting member 30 can be adjusted. can be adjusted.

Next, the installation structure of the fixing member 25 with adhesive mat will be explained. Of the two fixing members 25 with adhesive mats included in the fixture 11, the lower fixing member 25 with adhesive mats is the first fixing member 251, and the upper fixing member 25 with the adhesive mat is the second fixing member 252. The second fixing member 252 is attached so that the second surface 20b of the adhesive mat 20 is attached to the lower surface 10a of the object to be fixed 10 such that the tip of the shaft portion 23 of the bolt-like member 21 faces the upper surface Fa of the installation portion F. It is worn. Therefore, the second fixing member 252 is a fixing object side fixing part that is attached to the fixing object 10. Further, the first fixing member 251 is connected to the second fixing member 252 via the connecting member 30 and is installed in the installation part F by the adhesive mat 20.

In the installation structure of the fixing member 25 with adhesive mat, the second surface 20b of the adhesive mat 20 of the first fixing member 251 is stuck to the upper surface Fa of the installation part F, and the second surface 20b of the adhesive mat 20 of the second fixing member 252 is attached to the upper surface Fa of the installation part F. 20b is attached to the lower surface 10a of the fixed object 10. In addition, in the installation structure of the fixing member 25 with an adhesive mat, the adhesive mat 20 of the first fixing member 251 has a desired adhesive force between the mat sticking surface 13a of the first fixing member 251 and the upper surface Fa of the installation part F. It has been compressively deformed in the thickness direction so that it can exhibit this. Similarly, the adhesive mat 20 of the second fixing member 252 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 member 252 and the lower surface 10a of the object 10 to be fixed. It has been compressed and deformed. In this embodiment, the adhesive mat 20 is compressed to have a thickness of 50% to 90% of the thickness before being compressed and deformed.

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 head end surface 22a is located at a position further back from the mat attachment surface 13a. As the adhesive mat 20 is compressed and deformed, a portion of the adhesive mat 20 along the surface direction that faces the head end surface 22a of the head 22 enters the head accommodating portion 14c. Further, a part of the adhesive mat 20 that has entered the head accommodating portion 14c is stuck to the head end surface 22a. Therefore, in the fixing member 25 with adhesive mat, the head end surface 22a of the head 22 is accommodated in the head accommodating portion 14c at a position where the adhesive mat 20 can be attached.

Among the portions of the adhesive mat 20 along the surface direction, the amount of compression is different between the portion facing the head end surface 22a of the head 22 and the portion not facing the head end surface 22a. Of the adhesive mat 20, the portion facing the head end surface 22a is compressed less than the portion not facing the head end surface 22a. In the present embodiment, in the adhesive mat 20, the portions facing the head end surface 22a are provided between the head end surface 22a and the lower surface 10a and between the head end surface 22a and the upper surface Fa. Further, in the adhesive mat 20, the portions not facing the head end surface 22a are provided between the mat adhering surface 13a and the lower surface 10a, and between the mat adhering surface 13a and the upper surface Fa.

The portion of the adhesive mat 20 facing the head end surface 22a is compressed to a thickness of 50% to 90% of the thickness before compression. The amount of compression in the adhesive mat 20 at a portion facing the head end surface 22a is smaller than the amount of compression at a portion not facing the head end surface 22a.

In the adhesive mat 20, the difference in the amount of compression between a portion facing the head end surface 22a and a portion not facing the head end surface 22a is preferably 10% or less. That is, in the adhesive mat 20, the depth D of the bulging portion 14 is set such that the difference in compression amount between the portion facing the head end surface 22a and the portion not facing the head end surface 22a is 10% or less. regulated.

As shown in FIG. 1 or 5, in the installation structure of the fixing member 25 with an adhesive mat, the protruding part 17 of the first fixing member 251 has a slope 19 including a tip edge 19a separated from the upper surface Fa of the installation part F. ing. 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 member 252, 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.

That is, before the installation structure of the fixing member 25 with adhesive mat is constructed, the inclined surface 19 is held back from the second surface 20b of the adhesive mat 20, so that the installation structure is constructed and the adhesive mat 20 is compressed. Also, the inclined surface 19 and each surface 10a, Fa are separated from each other. 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 member 251, the four side edges of the adhesive mat 20 are exposed between the tip edge 19a of the inclined surface 19 and the upper surface Fa of the installation part F, and from the recess 18, and in the second fixing member 252, The four side edges of the adhesive mat 20 are exposed between the tip edge 19a of the inclined surface 19 and the lower surface 10a of the object to be fixed 10, and from the recess 18, respectively.

Next, a method for installing the fixture 11 having the adhesive mat-attached fixing member 25 will be explained.
First, in the 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 installation part F. shorten.

Next, on the upper surface Fa of the installation part F, the 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 member 251 is placed on the upper surface Fa. Then, the connecting member 30 is rotated to bring the second fixing member 252 closer to the object 10 to be fixed, and the second surface 20b of the adhesive mat 20 is stuck to the lower surface 10a of the object 10 to be fixed. Further, the connecting member 30 is rotated to bring the second fixing member 252 closer to the object to be fixed 10 . Then, the adhesive mat 20 of the first fixing member 251 and the adhesive mat 20 of the second fixing member 252 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 to a thickness of 50% to 90% of the thickness of the adhesive mat 20 before being compressed and deformed.

Further, the connecting member 30 is rotated such that the protruding part 17 of the first fixing member 251 is separated from the upper surface Fa of the installation part F, and the protruding part 17 of the second fixing member 252 is separated from the lower surface 10a of the fixed object 10. Adjust the amount.

Then, the second surface 20b of the adhesive mat 20 of the first fixing member 251 is attached to the upper surface Fa of the installation part F, and the second surface 20b of the adhesive mat 20 of the second fixing member 252 is attached to the fixing target 10. It is attached to the lower surface 10a. As a result, the fixing object 10 is fixed to the installation part F by the fixture 11. At the same time, the installation structure of the fixture 11 and the fixing member 25 with adhesive mat is constructed.

Note that there may be cases where it is necessary to peel off the fixing portion main body 13 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. The tip of a crowbar-shaped tool is inserted into the recess 18, and the tool is scooped out with the tip of the tool aimed at the mat attachment surface 13a. Then, the fixing portion main body 13 can be peeled off from the adhesive mat 20.

Next, the functions of the fixing tool 11, the fixing member 25 with adhesive mat, and the installation structure thereof will be explained.
Now, when an earthquake occurs, the installation part 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. At this time, the entire second surface 20b of the adhesive mat 20 is adhered to each surface 10a, Fa. Therefore, peeling of the adhesive mat 20 from each surface 10a, Fa is suppressed.

Further, as shown in FIG. 7, when the adhesive mat 20 is further compressed, the protruding portion 17 of the first fixing member 251 near the compressed portion comes into contact with the upper surface Fa of the installation portion F. Due to the partial compression of the adhesive mat 20, the first fixing member 251 is inclined, so that the inclined surface 19 comes into surface contact with the upper surface Fa of the installation portion F. Also in the second fixing member 252, the protrusion 17 near the compressed portion contacts the lower surface 10a of the fixing target 10.

According to the above embodiment, the following effects can be obtained.
(1) The fixing portion main body 13 of the fixing member 25 with adhesive mat includes a bulge 14 . Then, by inserting the shaft portion 23 of the bolt-like member 21 into the through-hole 16a of the bulging portion 14 and bringing the head 22 of the bolt-like member 21 into contact with the annular bottom portion 16, the bolt-like member 21 is inserted into the head accommodating portion 14c. The head 22 of the member 21 can be accommodated. Therefore, compared to the case where the head accommodating portion 14c is not provided and the head 22 is brought into direct contact with the mat adhesion surface 13a, the amount of protrusion of the head 22 from the mat adhesion 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 sticking surface of the adhesive mat 20 is reduced. Do not reduce. 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.

(2) The depth D of the bulge 14 is made larger than the head length L of the head 22. For this reason, 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 kept away from the mat attachment surface 13a of the fixing part main body 13. can be placed in position. As a result, it is possible to prevent the adhesive mat 20 from being excessively compressed between the head end surface 22a and each surface 10a, Fa, and to suppress a decrease in adhesive strength.

(3) 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 opposing side surface 22b of the head 22 is arranged to face the restriction surface 15a, and the rotation of the bolt-like member 21 can be restricted by contact between the restriction surface 15a and the side surface 22b of the head 22. Therefore, for example, when the bolt-like member 21 is rotated in order to screw the shaft portion 23 of the bolt-like member 21 into the connecting member 30, the bolt-like member 21 and the fixing portion main body 13 can be rotated together.

(4) In the installation structure of the fixing member 25 with adhesive mat, 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 The amount of approach of the fixing part main body 13 to the surfaces 10a and Fa is adjusted. Therefore, material destruction due to excessive compression of the adhesive mat 20 can be avoided, and a decrease in the adhesive strength of the adhesive mat 20 can be suppressed. Further, it is possible to avoid weakening of the tensioning force of the fixing tool 11 due to the fact that the adhesive mat 20 is not compressed, and it is possible to suppress the deterioration of the fixing function of the fixing tool 11.

(5) 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.

(6) A bead 12a is provided to reinforce the fixing part main body 13, and the inside of the 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.

(7) The adhesive mat 20 is compressed and deformed between the mat sticking surface 13a and each surface 10a, Fa, but the protruding portion 17 is separated from each surface 10a, Fa. When the adhesive mat 20 is compressed due to earthquake shaking, the protruding portions 17 come into contact with the respective surfaces 10a and Fa, thereby suppressing further compressive deformation of the adhesive mat 20. It is possible to suppress a decrease in the adhesive force due to excessive compressive deformation of the adhesive mat 20, and it is possible to maintain the state in which the object 10 to be fixed is fixed to the installation part F by the fixture 11.

(8) The portion of the adhesive mat 20 facing the head end surface 22a is compressed to a thickness of 50% to 90% of the thickness before compression. Therefore, even if there are parts of the adhesive mat 20 that face the head end surface 22a and parts that do not face the head end surface 22a, it is possible to suppress a decrease in adhesive force due to excessive compressive deformation of the adhesive mat 20.

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.
(9) In the installation structure of the fixing member 25 with adhesive mat, the adhesive mat 20 is compressed and deformed between the mat sticking surface 13a and each surface 10a, Fa, but the protrusion 17 is compressed between each surface 10a, Fa. separated from. 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 installation portion F.

○ As shown in FIG. 8, in the fixing member 25 with an adhesive mat, the depth D of the bulging portion 14 is set so that the head end surface 22a of the head 22 protrudes from the mat attachment surface 13a. Good too. In this case, the head length L is greater than the depth D.

In the installation structure of the fixing member 25 with adhesive mat, 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. is compressed into. In addition, the adhesive mat 20 is compressed with a larger amount of compression in a region between the head end surface 22a and each surface 10a, Fa than in a region between the mat sticking surface 13a and each surface 10a, Fa. .

With this configuration, the head 22 of the bolt-like member 21 can be 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. The area of the landing surface does not 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.

In addition, in the adhesive mat 20, by adjusting the amount of compression in the area facing the head end surface 22a and the area facing the mat attachment surface 13a, the material due to excessive compression of the adhesive mat 20 can be adjusted. Breakage can be avoided and decrease in adhesive strength can be suppressed.

○ As shown in FIG. 9, in the fixture 11 and the fixing member 25 with adhesive mat, the bulging portion 14 is arranged so that the head end surface 22a of the head 22 is located on the same plane as the mat attachment surface 13a. A depth D may be set. In this case, the head length L and depth D are the same. Further, the adhesive mat 20 is compressed to a thickness of 50% to 90% of the thickness before compression, and the area between the head end surface 22a and each surface 10a, Fa, and the mat sticking surface 13a. The area between each surface 10a and Fa is compressed by the same amount of compression.

With this configuration, 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, there is no need to form a hole in the adhesive mat 20 through which the head 22 passes. The area of the adhesive surface of the adhesive mat 20 does not need to be reduced. As a result, it is possible to eliminate a decrease in adhesive strength due to a decrease in the area of the adhesive mat 20 to which it is attached.

The fixture 11 may be configured to include one fixing member 25 with an adhesive mat, a connecting member 30, and an installation member. In this case, the installation member is installed on the one of the fixed object 10 and the installation part F to which the adhesive mat 20 of the adhesive mat-attached fixing member 25 is not attached. Furthermore, the installation member is not particularly limited to the structure of the fixing member 25 with adhesive mat, as long as it has a male thread that is screwed into the female threaded hole 30a of the connecting member 30.

○ In the fixing part 12, the fixing part main body 13 does not need to be provided with the protruding part 17. In this case, the fixing portion main body 13 does not include the recess 18 either.
○ 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.

○ As shown in FIG. 10 or 11, in the fixing member 25 with an adhesive mat, a gap forming recess 20c may be provided on the second surface 20b of the adhesive mat 20 of the fixing part 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 installation part F, the surface to which the second surface 20b is attached and the gap forming recess 20c are connected. A gap J may be formed between them.

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 fixture 11 having the fixing member 25 with an adhesive mat, the adhesive mat 20 of the first fixing member 251 is stuck to the upper surface Fa of the installation part F, which is the installation surface of the object 10 to be fixed, and The adhesive mat 20 of the second fixing member 252 is attached to the object 10 to be fixed. Therefore, the adhesive mat 20 of the second fixing member 252 constitutes a fixed object side adhesive mat, and the second fixing member 252 constitutes a fixed object side fixing part.

The fixture 11 is attached to the lower surface 10a of the object to be fixed 10 and the upper surface Fa of the installation part F with the adhesive mat 20, so that there is a first fixing member between the object to be fixed 10 and the installation part F. An installation structure for the member 251 and the second fixing member 252 has been constructed.

In the fixing structure of the first fixing member 251, the adhesive mat 20 between the upper surface Fa of the installation part F and the mat sticking surface 13a is compressed and deformed with a gap J secured by the gap forming recess 20c.

When configured in this way, it may be necessary to peel off the adhesive mat 20 from the upper surface Fa of the installation portion F. At this time, when the release agent is sprinkled on the upper surface Fa of the installation portion 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 attachment surface 13a of the first fixing member 251, and the tool is scooped out. Then, the adhesive mat 20 can be peeled off from the upper surface Fa of the installation part 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 installation part 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 release agent injection port may be formed in the bead 12a.
○ 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. .

○ The fixing part 12 may be made of resin.
○ 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 members 25 with adhesive mats of the fixture 11, only the fixing part 12 of one fixing member 25 with adhesive mat is provided with a protrusion 17, and the fixing part 12 of the other fixing member 25 with adhesive mat is provided with a protrusion 17. The protrusion 17 may not be provided.

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 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.
○ 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.

○ In the fixing member 25 with an adhesive mat, the shape of the mat sticking surface 13a of the fixing part main body 13 and the shape of the adhesive mat 20 do not have to match; for example, while the mat sticking surface 13a is square-shaped, , the adhesive mat 20 may have an oval shape.

○ The fixed object 10 does not need to be fixed to the installation part F by the fixture 11. Specifically, the object to be fixed 10 fixed to the installation part by another fixture may be further fixed to the installation part F by the fixture 11.

The fixing part main body 13 does not have to be in the shape of a square plate. For example, the fixing part main body 13 may be in the shape of a disk, a pentagonal plate, or a hexagonal plate.
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.
