[0017] In order to make the above features and advantages of the present invention more understandable, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0018] refer to Figure 1 and Figure 2

[0019] A cap beam frame piece welding operation platform comprises a rectangular frame formed by a pair of transverse square steels 11 and a pair of vertical square steels 12 fixedly connected, wherein an oblique square steel 14 is arranged at a corner between the transverse square steel and the vertical square steel in the rectangular frame, and the transverse square steel, the vertical square steel and the oblique square steel are all provided with a fixing device 2 for clamping the frame piece steel bar 3. The operation platform is manufactured according to the size of the cap beam frame piece, and the number of fixing devices is arranged on the operation platform according to the welding points of the frame piece steel bar.

[0020] In this embodiment, in order to improve the strength of the operating platform, the horizontal square steel and the vertical square steel, as well as the two ends of the oblique square steel and the corresponding horizontal square steel and vertical square steel are fixed by welding. Vertical channel steels 13 are arranged at equal intervals in the horizontal direction in the rectangular frame, and the two ends of the vertical channel steels are welded to the corresponding horizontal square steels to form an operating platform.

[0021] In this embodiment, the fixing device includes a base plate 21, one end of which is provided with an upper convex plate 22, and the other end of the base plate is provided with an inverted L-shaped plate 23, the inverted L-shaped plate and the base plate cooperate to form a groove 24 for embedding transverse square steel, vertical square steel or oblique square steel, and the inverted L-shaped plate is provided with a pushing component for pushing the transverse square steel, vertical square steel or oblique square steel to clamp the skeleton sheet steel bars.

[0022] In this embodiment, the push assembly includes a threaded hole arranged on the vertical plate of the inverted L-shaped plate, and an adjusting bolt 25 is threaded in the threaded hole, the inner end of which is used to abut against the horizontal square steel, the vertical square steel or the oblique square steel.

[0023] In this embodiment, the section of the adjusting bolt located on the outer side of the inverted L-shaped plate is threaded with a locking nut 26, so that the adjusting bolt is locked by the locking nut.

[0024] In this embodiment, the bottom plate, the upper convex plate, and the inverted L-shaped plate are made of metal materials and are integrally formed, such as steel or aluminum alloy plates.

[0025] Working principle and operation method: Place the horizontal square steel, vertical square steel or oblique square steel in the notch of the fixing device, place the skeleton sheet steel bars in the reserved groove 27 formed by the horizontal square steel, vertical square steel or oblique square steel and the upper plate, and fix the skeleton sheet steel bars by rotating the adjusting bolts. After the cap beam skeleton sheet steel bars are cut, they are placed in the rectangular frame of the operating platform according to the steel bar number, and the fixing device is installed according to the steel bar connection node. The fixing device can be adjusted according to the size and quantity of the welded steel bars. After the skeleton sheet steel bars are in place, turn the adjusting bolts to firmly fix the skeleton sheet steel bars on the operating platform, which provides a guarantee for the subsequent welding of the skeleton sheet steel bars. After they are firmly fixed, welding operation can be carried out. After all the skeleton sheet steel bars are firmly welded, loosen them by turning the adjusting bolts in the opposite direction.
