In summary, the material of the operation and maintenance pedal 2 according to the embodiment of the present invention is not limited. It should be noted that the roof panel 3 is made of a material having a certain strength and not easy to bend, such as a stainless steel material, and the steel material should satisfy a certain yield strength, so that the yield strength of the roof panel 3 can be between 310MPa and 345MPa, for example, 310MPa, 320MPa, 330MPa, 340MPa, and the like, and a certain pressure of the roof panel 3 in the embodiment of the present invention is ensured.

In order to fix the operation and maintenance pedal 2 on the roof panel 3, in the embodiment of the utility model, the operation and maintenance pedal 2 is fixed on the roof panel 3 by the clamping device 1, and the specific structure of the clamping device 1 is as follows:

The holder 11 may be an integral long structure or a long structure formed by connecting a plurality of pieces, which is not limited in the embodiment of the present invention. In addition, the size of the clamping cavity 111 is determined according to the size of the corrugated rib 31, and the shape of the clamping cavity 111 is determined according to the shape of the corrugated rib 31, which is not limited in the embodiment of the present invention.

In the case that the clamping member 11 is fixed to the tile rib 31 through the clamping cavity 111, the maintenance pedal 2 can be firmly fixed to the roof panel 3 by the cooperation of the clamping member 11 and the fixing member 12.

Specifically, the fixing element 12 includes a fixing portion 121 and a limiting portion 122, both the fixing portion 121 and the limiting portion 122 may be square plate-shaped structures, and the fixing portion 121 and the limiting portion 122 may be formed by bending a single plate or by welding a plurality of plates to each other. In order to enable the limiting part 122 to be tightly attached to the surface of the operation and maintenance pedal 2, the fixing part 121 protrudes out of the surface of the limiting part 122, so that a sufficient connecting space is reserved for the fixing part 121 and the second end of the clamping piece 11, the fixing part 121 and the second end of the clamping piece 11 can be in a threaded connection mode or a clamping connection mode, and the fixing part 121 is fixed on the clamping piece 11. And because the clamping piece 11 is fixed on the tile rib 31 through the clamping cavity 111 to realize the fixation with the roof panel 3, the relative position of the fixing piece 12 and the roof panel 3 can be fixed. Like this, when fixing fortune dimension footboard 2 on roof boarding 3, only need make fortune dimension footboard 2 all by spacingly in two not equidirectional through spacing portion 122, can be so that fortune dimension footboard 2 firm fixed mutually with roof boarding 3.

Specifically, the limiting portion 122 may include at least two intersecting limiting surfaces, and the at least two intersecting limiting surfaces are respectively attached to the top wall and the side wall of two adjacent operation and maintenance pedals 2. Illustratively, the limiting portion 122 includes two side plates, the planes of the plate surfaces of the two side plates are perpendicular to each other, when the fixing member 12 is assembled on the operation and maintenance footboard 2, one side plate is tightly attached to the top wall of the operation and maintenance footboard 2 to prevent the operation and maintenance footboard 2 from moving in a direction away from the roof panel 3, and the other side plate is tightly attached to the side wall of the operation and maintenance footboard 2 to prevent the operation and maintenance footboard 2 from moving in an extending direction of the roof panel 3, so that the operation and maintenance footboard 2 is finally firmly fixed to the roof panel 3. It should be noted that, in the embodiment of the present invention, the top wall and the side walls are two surfaces of the operation pedal 2 that are perpendicular to each other, that is, in the case that the operation pedal 2 is a square plate, the top wall is a surface of the operation pedal 2 that is away from the roof plate 3, and the side walls are surfaces of the long sides of the operation pedal 2 that are perpendicular to the plane of the top wall.

As can be seen from the above embodiments, in the embodiment of the present application, since the first end of the clamping member 11 has the clamping cavity 111, and the tile rib 31 is limited in the clamping cavity 111, the clamping member 11 can be fixed on the tile rib 31 through the clamping cavity 111 to achieve the fixation with the roof panel 3, so that the relative position of the clamping device 1 and the roof panel 3 is also fixed. Because the fixing member 12 includes the fixing portion 121 and the limiting portion 122, the fixing portion 121 protrudes from the surface of the limiting portion 122, the fixing portion 121 is fixedly connected to the second end of the clamping member 11, and the limiting portion 122 is disposed to be close to the surfaces of two adjacent operation and maintenance pedals 2 and is used for limiting the movement of the operation and maintenance pedals 2 in at least two directions, so that on the premise that the relative positions of the clamping device 1 and the roof panel 3 are fixed, the operation and maintenance pedals 2 can be relatively fixed to the roof panel 3 under the limiting effect of two limiting surfaces of the limiting member, and further the operation and maintenance pedals 2 and the roof panel 3 cannot be displaced, so that the operation and maintenance pedals 2 can be firmly fixed to the roof panel 3. In summary, the clamping device 1 provided by the embodiment of the utility model can firmly fix the operation and maintenance pedal 2 with the roof panel 3 only by matching and connecting the clamping piece 11 and the fixing piece 12, so that fewer mounting parts are needed in the whole mounting process, the process is simpler, the operation and maintenance are convenient, the hidden danger in the mounting process is reduced, the difficulty in later maintenance and replacement is reduced, and the maintenance and replacement cost is reduced.

Alternatively, as shown in fig. 2, the holder 11 includes a first holding piece 112 and a second holding piece 113; the second clamping piece 113 comprises a first clamping portion 1131 and a second clamping portion 1132, the second clamping portion 1132 is located at the first end of the first clamping portion 1131, and the plane of the first clamping portion 1131 is perpendicular to the plane of the second clamping portion; the second end of the first clamping portion 1131 faces the surface of the first clamping piece 112, and is provided with a groove, the first clamping piece 112 is detachably connected to the first clamping portion 1131, and the first clamping piece 112 covers the notch of the groove to form the clamping cavity 111.

Specifically, the first clamping piece 112 and the second clamping piece 113 are both bar-shaped pieces, the length of the first clamping piece 112 is equal to the length of the second clamping piece 113, and the length of the first clamping piece 112 is determined by the length of the tile rib 31 and the thickness of the operation and maintenance pedal 2. The first clamping piece 112 includes a first clamping portion 1131 and a second clamping portion 1132, an extending direction of the first clamping portion 1131 is perpendicular to an extending direction of the second clamping portion 1132, the first clamping portion 1131 and the first clamping piece 112 are oppositely arranged, that is, a plane where the first clamping portion 1131 is located is perpendicular to a plane where the second clamping portion 1132 is located, and the first clamping portion 1131 and the second clamping portion 1132 form an inverted "L" shaped structure. Thus, the second clamping portion 1132 may be connected to the fixing portion 121 by the first clamping portion 1131 and the first clamping piece 112 being coupled together.

In addition, the surface of the second end of the first clamping portion 1131 facing the first clamping piece 112 is provided with a groove, that is, the notch of the groove faces the first clamping piece 112, and in the case that the first clamping piece 112 is detachably connected to the first clamping portion 1131, the first clamping piece 112 can cover the notch of the groove to form the clamping cavity 111. When the clamping member 11 is fixed on the tile rib 31, the first clamping piece 112 and the second clamping piece 113 can be disassembled firstly, and after the tile rib 31 is positioned in the groove, the first clamping piece 112 and the second clamping piece 113 are fixed, so that the first clamping piece 112 and the second clamping piece 113 can be clamped at two sides of the tile rib 31. In this way, the first clamping piece 112 and the second clamping piece 113 can be connected in a matching manner, so as to conveniently fix the clamping member 11 on the tile rib 31, and meanwhile, the second clamping portion 1132 of the second clamping piece 113 can provide sufficient installation space for the fixing portion 121, so that the structure of the whole clamping device 1 is more compact.

Optionally, the clamping device 1 further comprises a first bolt and a first nut; a first through hole is formed at the first end of the first clamping part 1131, a second through hole is formed on the first clamping piece 112, and the first through hole and the second through hole are aligned; the first bolt penetrates through the second through hole and the first through hole in sequence and is connected with the first nut in a matched mode.

It should be noted that, since the first end of the first clamping portion 1131 is provided with the first through hole, and the first clamping piece 112 is provided with the second through hole, when the first bolt sequentially passes through the second through hole and the first through hole and is connected with the first nut in a matching manner, when the first clamping piece 112 and the second clamping piece 113 are fixed, the fastening degree between the first clamping piece 112 and the second clamping piece 113 can be controlled by controlling the matching amount of the first bolt and the first nut, so that the first clamping piece 112 and the second clamping piece 113 are fixed more firmly. In addition, because the first clamping piece 112 and the second clamping piece 113 are fixed through the matching connection of the first bolt and the first nut, when the clamping piece 11 is detached from the tile rib 31, only the first bolt and the first nut need to be separated, and the later maintenance and replacement of the clamping device 1 are more convenient.

It should be noted that, because the size of the notch of the groove is greater than the size of the groove bottom of the groove, that is, the area of the notch of the groove is greater than the area of the groove bottom of the groove, when the first clamping portion 1131 is installed on the tile rib 31, the convex portion of the tile rib 31 is more conveniently and gradually inserted into the groove, so that the notch of the groove can more conveniently fix the tile rib 31.

Optionally, one end of the tile rib 31 away from the roof panel 3 has a bent structure, the bent structure protrudes from a surface of the tile rib 31, a gap is formed between a surface of the first clamping portion 1131 facing the first clamping piece 112 and the first clamping piece 112, and the tile rib 31 passes through the gap to limit the bent structure in the groove.

It should be noted that, since there is a gap between the surface of the second end of the first clamping portion 1131 facing the first clamping piece 112 and the first clamping piece 112, that is, there is a gap between the end of the second end of the first clamping portion 1131 and the first clamping piece 112, an installation space can be reserved for the main body portion of the tile rib 31 through the gap, so that the clamping area of the clamping member 11 and the tile rib 31 is increased, the clamping member 11 and the tile rib 31 are fixed more firmly, and the fastening degree between the clamping device 1 and the roof panel 3 is further enhanced. And because the end of the tile rib 31 far away from the roof panel 3 has a bending structure, the bending structure protrudes out of the surface of the tile rib 31, and the tile rib 31 passes through the gap to limit the bending structure in the groove, a certain limiting effect can be formed on the tile rib 31 at the end of the second end of the first clamping part 1131, so that the clamping device 1 is more firmly installed.

Alternatively, as shown in fig. 3 to 5, the fixing portion 121 includes a first fixing plate 1211 and a second fixing plate 1212; the plane of the first fixing plate 1211 is perpendicular to the plane of the second clamping portion 1132, the plane of the second fixing plate 1212 is parallel to the plane of the second clamping portion 1132, the edge of the first fixing plate 1211 is fixedly connected to the edge of the second fixing plate 1212, and the second fixing plate 1212 is fixedly connected to the second clamping portion 1132, wherein a projection of the plate surface of the second fixing plate 1212 along the direction perpendicular to the plane of the second clamping portion 1132 has no overlap with the plate surface of the limiting portion 122.

It should be noted that, because the plane of the first fixing plate 1211 is perpendicular to the plane of the second clamping portion 1132, the plane of the second fixing plate 1212 is parallel to the plane of the second clamping portion 1132, and the edge position of the first fixing plate 1211 is fixedly connected to the edge position of the second fixing plate 1212, the surface of the first fixing plate 1211 is perpendicular to the surface of the second fixing plate 1212, the plate surface of the second fixing plate 1212 faces the second clamping portion 1132, and the plate surface of the first fixing plate 1211 is perpendicular to the second clamping portion 1132, when the fixing member 12 is connected to the clamping member 11, the second fixing plate 1212 can be directly connected to the second clamping portion 1132 in a matching manner. And because the projection of the plate surface of the second fixing plate 1212 along the plane direction perpendicular to the second clamping portion 1132 is not overlapped with the plate surface of the limiting portion 122, the fixing portion 121 protrudes from one side of the limiting portion 122, so that the connection between the fixing portion 121 and the clamping member 11 does not affect the limiting function of the limiting portion 122, the structure of the whole clamping device 1 is further made more compact, and an installation space can be created for the limiting portion 122 to cling to the operation and maintenance pedal 2.

Optionally, the clamping device 1 further comprises a second bolt and a second nut; a third through hole is formed in the middle of the second fixing plate 1212, a fourth through hole is formed in the middle of the second clamping portion 1132, and the third through hole and the fourth through hole are aligned; and the second bolt sequentially penetrates through the third through hole and the fourth through hole and is connected with the second nut in a matching manner.

It should be noted that, because the middle of the second fixing plate 1212 is provided with a third through hole and the middle of the second clamping portion 1132 is provided with a fourth through hole, when the second bolt sequentially passes through the third through hole and the fourth through hole and is connected with the second nut in a matching manner, the amount of the second bolt and the second nut can be controlled when the clamping member 11 and the fixing member 12 are fixed; the degree of tightness between the second retaining plate 1212 and the second clamping portion 1132 is increased, so that the second retaining plate 1212 and the second clamping portion 1132 are more firmly fixed to each other. In addition, since the second fixing plate 1212 and the second clamping portion 1132 are fixed by the first bolt and the first nut in a matching manner, when the fixing member 12 and the clamping member 11 are disassembled, only the second bolt and the second nut need to be separated, which is more convenient for later maintenance and replacement of the clamping device 1.

Optionally, the limiting portion 122 includes a first limiting plate 1221 and two second limiting plates 1222; the first fixing plate 1211 is fixed in the middle of the edge position of the first limit plate 1221, and the plane of the first fixing plate 1211 is perpendicular to the plane of the first limit plate 1221; the two second limiting plates 1222 are respectively located at two sides of the first fixing plate 1211, the plane of the second limiting plate 1222 is perpendicular to the plane of the first limiting plate 1221, and the first fixing plate 1211 and the second limiting plate 1222 are respectively located at two sides of the plane of the first limiting plate 1221; under the condition that the fixing portion 121 is fixedly connected with the second end of the clamping member 11, the first limiting plate 1221 is tightly attached to the top walls of two adjacent operation and maintenance pedals 2, and the two second limiting plates 1222 are respectively tightly attached to the side walls of two adjacent operation and maintenance pedals 2.

It should be noted that, since the plane where the second limit plate 1222 is located is perpendicular to the plane where the first limit plate 1221 is located, the limit directions of the two limit surfaces formed by the limit portion 122 are perpendicular to each other, so that the operation and maintenance pedal 2 can be limited in different directions by the limit portion 122, and the position of the operation and maintenance pedal 2 is more stable.
