After the presetting operation is completed, the end wefts 12 of the bridge body 10 to be assembled are firstly aligned with the second pressing wave band 312 of the side wall quick-connecting piece 20A and the second pressing wave band 312 of the base quick-connecting piece 20B, the end wefts 12 on one side wall 14 are inwards pressed into the corresponding second pressing wave band 312 of the side wall quick-connecting piece 20A, the end wefts 12 of the base 15 are inwards abutted against the second pressing wave band 312 of the base quick-connecting piece 20B, the lower end of the guide surface 321 of the other side wall quick-connecting piece 20A is abutted against the corresponding top side wall warps 131, as shown in fig. 9, as the side wall quick-connecting piece 20A is pressed downwards, the guide surface 321 gradually abuts against the side wall warps 131, the corresponding end wefts 12 are gradually guided into the second pressing wave band 312 until the free end 32 is not abutted against the top side wall 131, the corresponding end wefts 12 are pressed into the second pressing wave band warps 312 by the resilience force of the locking part 30 and the side wall, at the same time, the end weft threads 12 of the base 15 are also pressed into the second pressing wave band 312 of the base quick connector 20B, and the assembly is complete, as shown in fig. 10. Therefore, through one-step buckling operation, the side walls 14 and the bases 15 of the two bridge frame bodies 10 are locked by the quick connectors, safety and efficiency are achieved, the preset installation of each quick connector 20 can be less than 2s, if the quick connectors are subjected to on-site buckling operation after presetting, the assembly can be completed within 1s as soon as possible, the assembly of the traditional connectors needs 5min, meanwhile, the cost of the quick connectors is low, the cost of the three quick connectors 20 is only 1 yuan approximately, the cost of the traditional connectors is 7-8 yuan/group in a large summary, and the cost is greatly reduced.

Meanwhile, the end part weft 12 can be respectively pressed on the first pressing wave band 311 and the second pressing wave band 312 due to the elastic pretightening force of the locking part 30 and the resilience force of the side wall 14, and is reversely pressed and tightened due to the deviating arrangement.

Wherein the base quick connector 20B helps to maintain the horizontal position of the two bridge bodies 10 so that the bridge bodies 10 do not shift, do not have a high or low condition, do not affect the placement of cables, and help the side wall quick connectors 20A on both sides to lock the end weft wires 12 in a fixed position.

When horizontal external force or vertical external force is applied to the bridge body 10, because the two end wefts 12 are arranged in a back-to-back manner, the side wall warps 131 are gripped by the claw bodies 211 of the side wall quick-connecting pieces 20A on the two sides vertically and outwards, the base warps 132 are gripped by the claw bodies 211 of the base quick-connecting pieces 20B horizontally, and no matter which direction of external force is, the base warps 132 are gripped by the external force more, for example, when the pressure level is outwards, the base warps 132 are gripped by the claw bodies 211 of the base quick-connecting pieces 20B horizontally, the side wall warps 131 are gripped by the claw bodies 211 of the side wall quick-connecting pieces 20A vertically, and the limiting parts 212 are deeply clamped between the two side wall warps 131, so that the side wall warps 131.

During disassembly, only one hand is needed to hold the side wall 14 of the bridge body 10, the thumb of the other hand correspondingly abuts against the free end 32 of the side wall quick connector 20A, the free end 32 is pushed inwards, the free end 32 is released from the side wall warps 131, the free end 32 moves upwards, the base 15 of the bridge body 10 and the end part wefts 12 of the other side wall 14 are also disconnected, one-step locking and one-step disassembly are achieved, the operation convenience is improved, time and labor are saved, the assembly cost is reduced, the safety of high-altitude operation is improved, and no external tool is needed.

Thereby, through the horizontal locking location of base quick-witted 20B to two crane span structure body 10 tip, through the vertical locking location of lateral wall quick-witted 20A to two crane span structure body 10 tips, realize the comprehensive locking to two crane span structure bodies 10, keep the reserve distance of crane span structure body 10 tip simultaneously, reduce the requirement of tip cutting planarization, improve work efficiency, simultaneously, base quick-witted 20B and lateral wall quick-connecting piece 20A only need lock two tip wefts 12, just can reach the locking effect of two crane span structure bodies 10, the volume is littleer, non-deformable, the cost is lower, be convenient for connect elbow district section 2, direct district section 1, tee bend district section 3 and cross district section 4.
