As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0026] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0027] Please refer to Figure 1-Figure 4 As shown, the present invention discloses a high-efficiency and high-strength channel steel fixing method, which includes steps S101-S103.

[0028] S101. Two channel steels which are vertically abutted or intersected by their extended lines in a plane are respectively the first channel steel and the second channel steel; one of the two adjacent side surfaces of the channel steel has a plurality of first through holes 201 arranged along its length direction with a spacing of a, and the other side surface has a plurality of second through holes 202 arranged along its length direction with a spacing of b, and a is not equal to b.

[0029] Specifically, Figure 1The first channel steel and the second channel steel are vertically connected, through holes are provided on the sides of the first channel steel and the second channel steel, and two adjacent sides of the channel steel are provided with a plurality of first through holes 201 and second through holes 202, the plurality of first through holes are evenly arranged along the length direction of the channel steel, and the spacing between two adjacent first through holes is a. The plurality of second through holes are evenly arranged along the length direction of the channel steel, and the spacing between two adjacent second through holes is b.

[0030] S102. Fix the first channel steel and the second channel steel by a fixing member, wherein the fixing member comprises a third through hole 11 matched with the first through hole and a fourth through hole 31 matched with the second through hole, the distance between two adjacent third through holes is b, and the distance between two adjacent fourth through holes is a.

[0031] Specifically, the fixing member is used to fix the first channel steel and the second channel steel, and the fixing member includes a third through hole and a fourth through hole. The first through hole cooperates with the third through hole, and the fourth through hole cooperates with the second through hole. The spacing between two adjacent third through holes is b, and the spacing between two adjacent fourth through holes is a.

[0032] S103, fix the fixing member and the first channel steel and / or the second channel steel by at least one bolt passing through the third through hole and the first through hole of the first channel steel and / or the second channel steel, and fix the fixing member and the first channel steel and / or the second channel steel by at least one bolt passing through the fourth through hole and the second through hole of the first channel steel and / or the second channel steel.

[0033] Specifically, the method fixes the fixing member 100 and the two channel steels 200 as a whole by bolts. The fixing member and the first channel steel and / or the second channel steel are connected by at least one bolt passing through the third through hole and the first through hole of the first channel steel and / or the second channel steel. The fixing member can be provided with a row of third through holes, or two rows of third through holes. When matched, at least one of the third through holes on the fixing member is aligned with the first through hole on the channel steel, and the fixing member and the channel steel are fixed together by bolts. The fixing member and the first channel steel and / or the second channel steel are connected by at least one bolt passing through the fourth through hole and the second through hole of the first channel steel and / or the second channel steel. The fixing member can be provided with a row of fourth through holes, or two rows of fourth through holes. At least one of the fourth through holes on the fixing member is aligned with the second through hole on the channel steel, and the fixing member and the two channel steels are fixed together by at least one bolt.

[0034] The commonly used fixing methods currently all adopt the same-spacing hole matching (that is, the spacing between the holes on the fixing part is e, and the spacing between the mating holes on the channel steel is also e). In this way, the precision of the adjustment holes between the fixing part and the channel steel is the spacing between two holes. However, in this application, it is set by matching through holes with different spacings. Specifically, the fourth through hole with a spacing of a on the fixing part is matched with the second through hole with a spacing of b on the channel steel, and the third through hole with a spacing of b on the fixing part is matched with the first through hole with a spacing of a on the channel steel. In this way, the precision of the adjustment holes between the fixing part and the channel steel is a - b (at this time, a > b; when a < b, the precision is b - a). This can reduce the number of holes opened on the channel steel, thereby increasing the mechanical strength of the channel steel.

[0035] In an alternative embodiment, the first through holes of two channel steels are in the same plane. The fixing part includes a first surface 10A and at least one second surface 30A. The first surface is parallel to the plane where the first through holes of the channel steel are located, and the second surface is perpendicular to the second surface. The third through hole is arranged on the first surface, and the fourth through hole is arranged on the second surface. Specifically, two channel steels are vertically connected in the same plane. The plane where the first through holes of the two channel steels are located is parallel to the plane where the two channel steels are located. The third through hole is arranged on the first surface, and the third through holes are arranged along the length direction of the two channel steels 200. One channel steel is connected to the fixing part by passing at least one bolt through one of the third through holes in one row and the first through hole, and the other channel steel is connected to the fixing part by passing at least one bolt through one of the third through holes in the other row and the first through hole. Finally, the fixing part and the two channel steels are connected together by passing at least one bolt through the fourth through hole and the second through hole. In an alternative embodiment, the first surface is L-shaped. The first surface includes a connected first sub-surface and second sub-surface. One row of third through holes is arranged on the first sub-surface, and the other row of third through holes is arranged on the second sub-surface. The first sub-surface and the second sub-surface are the same.

[0036] Such as Figure 1 And Figure 3As shown, in an optional embodiment, the number of fixing members is two, and the first surfaces of the two fixing members are opposite to each other; the second surface of one fixing member faces the other fixing member. Specifically, the present application fixes two channel steels into one body by two fixing members. The first surfaces of the two fixing members are arranged opposite to each other, and the second surface of one fixing member is arranged toward the other fixing member. In this embodiment, one channel steel is connected to the fixing member by at least one bolt passing through the third through hole on the first sub-surface on the first surface of the two fixing members and the first through hole on the channel steel, and the other channel steel is connected to the fixing member by at least one bolt passing through the third through hole on the second sub-surface on the first surface of the fixing member and the first through hole on the other channel steel. Then, the bolts are fixed to the two channel steels by passing through the fourth through hole on the second surface and the second through hole on the channel steel. The present application connects the channel steel and the fixing member on three perpendicular planes by at least four bolts, that is, the degrees of freedom in the three directions of X, Y, and Z are all restricted, and the stability is high and the installation is convenient.

[0037] In an optional embodiment, a=1.5b. That is, the fixing member and the channel steel are adjusted with an accuracy of 0.5b. In an optional embodiment, a=30mm, b=20mm. Specifically, the spacing between the first through holes on the channel steel is 30mm, the spacing between the second through holes is 20mm, the spacing between the third through holes on the fixing member is 20mm, and the spacing between the fourth through holes on the fixing member is 30mm. The third through hole cooperates with the first through hole, and the fourth through hole cooperates with the second through hole, so that the adjustment accuracy between the fixing member and the channel steel is 10mm. If holes with the same spacing are used in the market, in order to achieve an accuracy of 10mm, the spacing between the two holes must be set to 10mm, so that the channel steel may even be directly damaged, while the mechanical strength of the channel steel of the present application is greatly enhanced.

[0038] This application also protects the fixing parts used to implement the above-mentioned high-efficiency and high-strength channel steel fixing method, please refer to Figure 1-Figure 4 As shown, the present invention discloses a high-efficiency and high-strength channel steel fixing member 100, which is used to cooperate with another high-efficiency and high-strength channel steel fixing member to fix the channel steel. The fixing member includes a first vertical plate 10, a second vertical plate 20 and a vertical plate 30, the first vertical plate and the second vertical plate are arranged on the same plane, and the first vertical plate and the second vertical plate are connected at a right angle. The vertical plate is perpendicular to the plane where the first vertical plate and the second vertical plate are located. The vertical plate is connected to one side of the length direction of the first vertical plate or the second vertical plate, the vertical plate includes a plurality of fourth through holes 31 arranged along the length direction thereof, the first vertical plate includes a plurality of third through holes 11 arranged along the length direction thereof, and the second vertical plate includes a plurality of third through holes 11 arranged along the length direction thereof.

[0039] For details, please refer to Figure 2As shown, the fixing member of this embodiment is used in conjunction with another identical fixing member, the first vertical plate of the first fixing member is arranged opposite to the second vertical plate of the second fixing member, the second vertical plate of the first fixing member is arranged opposite to the first vertical plate of the first fixing member, and the vertical plate of the first fixing member is arranged in the direction of the second fixing member, and the vertical plate of the second fixing member is arranged in the direction of the first fixing member. That is, the first fixing member and the second fixing member form two accommodating cavities for accommodating the channel steel 200. The two channel steels are placed in the accommodating cavities respectively, and the channel steel and the fixing member are fixed together by bolts. In this embodiment, each channel steel is fixed with at least two bolts, and the bolts are fixed from two directions, ensuring the stability of the fixing between the fixing member and the channel steel. Therefore, each channel steel restricts the degree of freedom from two directions, and one direction is repeated in the two directions, that is, the bolts passing through the first vertical plate and the second vertical plate. Therefore, the present application fixes the channel steel by two sets of fixing members, and the present application restricts the degree of freedom of the channel steel by three mutually perpendicular directions, that is, the degree of freedom in the three directions of X, Y, and Z, and has high stability and is easy to install.

[0040] In an optional embodiment, the distance between every two fourth through holes is 1.5 times the distance between every two third through holes.

[0041] Specifically, the fixing member in this embodiment needs to be matched with the channel steel 200 with holes. The hole of the channel steel is adapted to the first through hole and the second through hole. When the channel steel is a C-shaped steel, the spacing between the openings on the bottom wall of the C-shaped steel is the same as the spacing between every two second through holes, and the spacing between the openings on the side wall of the C-shaped steel is the same as the spacing between every two first through holes. When the fixing member is matched with the C-shaped steel, the first through hole on the fixing member matches the opening on the side wall of the C-shaped steel, and the second through hole on the fixing member matches the opening on the bottom wall of the C-shaped steel, that is, when the fixing member is matched with the C-shaped steel, the spacing between the holes that match each other is not the same. This matching can be adjusted with an accuracy of 0.5 times the spacing between every two second through holes.

[0042] In some embodiments, the spacing between every two third through holes is 30 mm, and the spacing between every two first through holes is 20 mm. In this way, a bolt can be inserted every 10 mm to fix the upper and lower parts, and the left and right parts. In addition, a scale of 10 mm can be set on the channel steel to facilitate punching. In this embodiment, the diameter of the third through hole and the diameter of the first through hole are both set to 10 mm.

[0043] In some optional embodiments, the vertical plate is connected to the inner side of the first vertical plate or the second vertical plate.

[0044] The present application also protects a high-efficiency and high-strength channel steel fixing assembly, which includes two of the above-mentioned high-efficiency and high-strength channel steel fixing members. The first vertical plate of one of the fixing members is arranged opposite to the second vertical plate of the other fixing member. The vertical plate of one of the fixing members is arranged toward the other fixing member, that is, the two fixing members are arranged opposite to each other, and the two fixing members form two accommodating cavities for accommodating the channel steel. Finally, bolts are passed through the fixing members and the channel steel to fix the two channel steels.

[0045] The channel steel 200 used in conjunction with the above-mentioned fixing member in the present application can be a C-shaped steel or a square steel. When the channel steel is a C-shaped steel, a plurality of first through holes 201 are provided on two opposite sides of the channel steel, and a plurality of second through holes 202 are provided on the bottom surface of the channel steel. When installing the fixing member, the vertical plate on the fixing member covers the notch of the C-shaped steel, and finally the fixing member and the C-shaped steel are fixed by bolts. When the channel steel is a square steel, a plurality of sixth through hole portions are provided on two opposite sides of the square steel, and a plurality of seventh through hole portions are provided on the other two opposite sides of the square steel.

[0046] In an optional embodiment, the channel steel is a C-shaped steel, and a groove portion 203 is provided on the side of the channel steel, and the first through hole and the second through hole are provided on the bottom wall of the groove portion. Or the channel steel is a square steel, and groove portions are provided on the four sides of the channel steel, and the sixth through hole portion or the seventh through hole portion is provided on the bottom wall of the recessed portion. The mechanical strength of the channel steel with the groove portion is higher, and the vertical plate, the first vertical plate and the second vertical plate on the fixing member used in conjunction with the channel steel can be provided with a positioning platform portion. During installation, the positioning platform portion 40 is placed in the groove portion and then aligned with the opening, which facilitates installation.

[0047] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention.
