The utility model relates to a portable bearing beam for reducing the pressure of a truck-mounted crane supporting leg on a floor, which is characterized in that the distance between secondary beams of the floor is 3000mm, the thickness of a floor is 150mm, the bearing beam comprises a plurality of bearing beam bodies, and the bearing beam is characterized in that the bearing beam bodies are H-shaped steel with the length of more than or equal to 4m, and steel plates are fixedly welded on the edges of the two sides of the H-shaped steel to reinforce the middle parts of the H-shaped steel; when the bearing beam is used, the H-shaped steel of the reinforced steel plate is subjected to spot welding with the supporting leg of the truck crane. The portable bearing beam for reducing the pressure of the supporting legs and the supporting feet of the truck crane on the floor has the advantages that sleepers or bearing plates do not need to be moved many times, operation is easy, maneuverability of the truck crane is greatly improved, time and labor are saved, and the manual carrying cost is saved; and the stress of the supporting leg position of the crane is effectively transmitted to the secondary beam or the position, close to the secondary beam, of the floor, and the structure of the floor is benefited.

    一种减少汽车吊支腿支脚对楼面压力的便携式垫梁,楼面次梁间距3000mm,楼板厚150mm,包括若干根垫梁本体,其特征在于:所述垫梁本体为长度≥4m的H型钢,在H型钢两侧边缘各固焊钢板进行中间部位加固;其中:所述垫梁使用时,经加固钢板的H型钢与汽车吊支腿支脚进行点焊焊接。本发明的减少汽车吊支腿支脚对楼面压力的便携式垫梁具有不再需要多次移动枕木或垫板,操作简单,汽车吊的机动性大幅度得到提升,省时省工,节约人工搬运成本,确保吊车支脚支腿位置受力有效的传递到次梁或楼板靠近次梁位置和对楼板结构有利的优点。
