These terms are primarily for the purpose of better describing the present invention and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0022] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0023] See Figure 1 This is a three-dimensional structural diagram of a prefabrication fixture for T-shaped and L-shaped profiles provided by this utility model. The prefabrication fixture includes a horizontal angle steel 1 and a vertical angle steel 2. The angle steel is a long strip of steel with two sides perpendicular to each other, forming an angle.

[0024] The horizontal side 11 of the horizontal angle steel is perpendicular to the first side 21 of the vertical angle steel, and the right angle formed by the two is used to abut against the panel 31 of the workpiece, and the surface of the panel is close to the horizontal side.

[0025] Three through holes are sequentially arranged along the long side of the second side 22 of the vertical angle steel. Bolts pass through the through hole farthest from the horizontal side and the through hole at one end of the fixing plate 23, and are fixed to the second side of the vertical angle steel with nuts 231. A folding plate 232 perpendicular to the fixing plate is provided at the other end of the fixing plate. When the fixing plate is in a horizontal position, the folding plate extends towards the horizontal side. The fixing plate rotates around the through holes, and the folding plate is used to limit the web plate 32 of the workpiece.

[0026] Two through holes, one furthest from the horizontal edge and the other two between them, correspond to elongated holes 241 on two adjustable limiting plates 24. Bolts pass through these through holes and elongated holes, and, in conjunction with wing nuts 242, fix the two adjustable limiting plates to the second side 22 of the vertical angle steel. The end faces of the two adjustable limiting plates should extend out of the first side of the vertical angle steel by the same length to ensure stable vertical standing of the web. The length direction of the elongated hole is parallel to the horizontal edge. The fixed position of the wing nut and bolt within the elongated hole determines the length of the end face of the adjustable limiting plate extending out of the first side of the vertical angle steel. This end face of the adjustable limiting plate abuts against the web surface of the workpiece, limiting the projection position of the web on the workpiece panel.

[0027] In use, first, the panel of the workpiece is placed on the horizontal edge of the horizontal angle steel, then the web of the workpiece is installed, the web is close to the end face of the adjustable limiting plate, the web is limited by the folding plate of the movable fixed clamping plate, the folding plate and the adjustable limiting plate are located on the two side faces of the web, the web is stably vertically erected; the gap between the web and the folding plate is further fixed and locked by the inclined wedge 233; the abutting position between the web and the waist plate is spot-welded, when the bolt is fixed at the leftmost end of the long hole of the adjustable limiting plate, the end face of the adjustable limiting plate is the longest to extend out of the first edge of the vertical angle steel, the projection position of the web on the panel is in the middle of the panel, forming a T-shaped section bar, see Figure 1 ; when the bolt is fixed at the rightmost end of the long hole of the adjustable limiting plate, the end face of the adjustable limiting plate is the shortest to extend out of the first edge of the vertical angle steel, the projection position of the web on the panel is close to the first edge of the panel, forming an L-shaped section bar, see Figure 2 . The inclined wedge used in the T-shaped section bar and the L-shaped section bar is different in size, which is determined according to the distance between the web and the folding plate.

[0028] Optionally, according to the other position of the bolt fixed in the long hole of the adjustable limiting plate, other special-shaped section bars required on site can be made.

[0029] After the spot welding is completed, the inclined wedge is disassembled and the movable fixed clamping plate is opened, the assembly work is completed, the workpiece is lifted, and the next step work can be carried out.

[0030] In another embodiment, see Figure 4 , when the workpiece is relatively long, a plurality of T-shaped section bars and L-shaped section bars are used to pre-assemble the tooling, which are placed in sequence along the length direction of the workpiece, the plurality of horizontal edges abut the panel of the workpiece, and the end face of the adjustable limiting plate of each pre-assembled tooling abuts the panel face of the web of the workpiece, so that the workpiece will not deviate during the spot welding process due to the excessive length of the workpiece.

[0031] The tooling is usually assembled freely on site by several sets of pre-assembled tooling.

[0032] The above is the preferred embodiment of the present application, it should be pointed out that, for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, these improvements and refinements are also considered as the protection scope of the present application.
