[0001] The present invention relates to the technical field of bridge construction, and more specifically, to an auxiliary tool for making a non-standard bridge elbow and a method for making and using the tool. Background Art

[0002] It is known that cable trays serve as the main cable channel and are composed of brackets, supports and installation accessories. Since the cable trays can be erected independently in buildings or attached to various buildings (structures) and pipe gallery brackets, they have the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance, and are widely used in industrial plants such as power plants and chemical plants. During the construction of cable trays in power plants, a large number of elbows need to be designed according to the on-site conditions, especially branch trays require a large number of non-standard elbows to adapt to the complex on-site environment. The common way to make elbows is that the construction personnel calculate the cutting width based on the Pythagorean theorem, then cut isosceles triangles, and then bend the cable tray to connect them.

[0003] However, in actual use, a large number of elbows need to be made for on-site branch cable trays, and the production process of the branch cable tray elbows needs to be based on the actual situation on site. The quality and ability of on-site workers are uneven; therefore, the calculation of the incision position when making non-standard cable tray elbows causes certain troubles for many inexperienced installers, and different installers have different ways of calculating the incision position when making non-standard cable tray elbows, resulting in non-uniform sizes of non-standard cable tray elbows made on site; therefore, an auxiliary tool for making non-standard cable tray elbows and a method for making and using the tool are proposed as a further improvement.

[0012] Furthermore, the scales on the scale sticker include: a regular scale and a cutting size scale; the color on the cutting size scale is the same as the corresponding color.

[0013] Furthermore, a strip hole for sliding of a connecting piece is opened at the center line position of the main ruler blank; and a round hole for installing the connecting piece is opened at the center position of the auxiliary ruler blank.

[0014] Furthermore, the corners of the main scale blank and the auxiliary scale blank are both rounded.

[0046] The main ruler blank 1 is connected to the auxiliary ruler blank 2 through a connecting piece 3.

[0047] The connecting member 3 may be a plum handle bolt, so as to fix the main ruler blank 1 and the auxiliary ruler blank 2; and both the main ruler blank 1 and the auxiliary ruler blank 2 may be rectangular ruler blanks;

[0048] A reference table 4 for calculating cutting dimensions is attached to one side of the main ruler blank 1 and the auxiliary ruler blank 2, and a scale sticker 5 for drawing cutting lines is attached to the other side of the main ruler blank 1 and the auxiliary ruler blank 2.

[0049] Embodiment 1: A 1000mm main scale blank 1 and a 400mm secondary scale blank 2 are produced by CAD; and 1000mm scale stickers 5 and 400mm scale stickers 5 are respectively pasted; and this embodiment is applicable to all bridge frames on site, but has the disadvantage of being large in size and inconvenient to carry.

[0050] Embodiment 2: A 400mm main ruler blank 1 and a 400mm secondary ruler blank 2 are produced by CAD; and 400mm scale stickers 5 and 400mm scale stickers 5 are pasted respectively;

[0051] Therefore, this embodiment is suitable for the upper and lower elbows of the on-site branch bridge with a width of less than 400 mm and the bridge with a width of more than 400 mm, and has the advantage of being small in size and more convenient to carry;

[0052] In summary, combined with the actual situation on site and the procurement situation of the bridge frame, since the design institute of the bridge frame above 400mm has issued more detailed drawings, finished elbows are purchased; thus, a small number of non-standard elbows need to be made on site; and the branch bridge frame is designed on site according to the needs of on-site users, and a large number of non-standard elbows need to be made on site, so embodiment 2 is more suitable for the actual needs of on-site construction.

[0053] In a preferred embodiment, as shown in the attached Figure 1 , attached drawings, Figure 3 and attached Figure 4 As shown, the reference table 4 for calculating the cutting size includes: bridge size 41, bridge elbow curvature 42, cutting size 43 and color 44;

[0054] The bridge size 41 is set to the bridge model used on site;

[0055] The curvature 42 of the bridge elbow is set to the curvature required for making the bridge elbow according to the on-site environment;

[0057] In a preferred embodiment, as shown in the attached Figure 1 , attached drawings, Figure 3 and attached Figure 4 As shown, the cutting size calculation reference table 4 is provided with eight bridge sizes 41 and four bridge elbow curvatures 42 , and one bridge size 41 and one bridge elbow curvature 42 correspond to one cutting size 43 and one color 44 .

[0058] Example: If the bridge size 41 is 150 mm, when the bridge elbow curvature 42 is required to be 45°, the cutting size 43 is 124 mm, and is displayed in yellow in the cutting size calculation reference table 4.

[0059] In a preferred embodiment, as shown in the attached Figure 1 , attached drawings, Figure 3 and attached Figure 4 As shown, the scales on the scale sticker 5 include: a regular scale 51 and a cutting size scale 52 ; the color on the cutting size scale 52 is the same as the corresponding color 44 .

[0060] Among them, the cutting size scale 52 information of the eight bridge sizes 41 in the cutting size calculation reference table 4 is accurately marked in the conventional scale 51; if the laser printing method is adopted, the scale is directly printed on the scale blank of the aluminum alloy material to enhance the wear resistance of the main scale blank 1 and the auxiliary scale blank 2; it has good practicality.

[0061] In a preferred embodiment, as shown in the attached Figure 1 , attached drawings, Figure 3 and attached Figure 4 As shown, a strip hole 11 for sliding of the connecting member 3 is opened at the center line position of the main ruler blank 1; a round hole 21 for installing the connecting member 3 is opened at the center position of the auxiliary ruler blank 2.

[0062] Among them, a strip hole 11 with a width of 6 mm and a length of 300 mm is cut out at the center line position of the main scale blank 1 by a cutting machine;

[0063] Among them, an M6 round hole 21 is opened at the center of the auxiliary ruler blank 2, and the connecting piece 3 adopts an M5 nut to fix the two.

[0064] In a preferred embodiment, as shown in the attached Figure 1 , attached drawings, Figure 3 and attached Figure 4 As shown, the corners of the main ruler blank 1 and the auxiliary ruler blank 2 are both rounded to prevent the main ruler blank 1 and the auxiliary ruler blank 2 from colliding with each other to cause personal injury or damage to objects.
