To achieve the goals above, technical solution used by the utility model is：A kind of aluminium section material bottom plate, including Floor body, one end of the floor body are provided with female connector, and the other end of the floor body corresponds to the female connector and sets It is equipped with pin end, the bottom of the female connector is provided with the long rib of L shape, and the bottom of the pin end corresponds to the long rib of L shape Inside is provided with the short rib of L shape, the pin end under connection status, on the inside of the long rib of L shape on the female connector with cooperation On the short rib of L shape on the outside of fitting completely, and the upper surface of two connected floor bodies is concordant.

Based on above-mentioned, the female connector top offers card slot, and the card slot is from the female connector outer end face along upwarping arc Shape curve extends internally, and the pin end top corresponds to the card slot and is provided with arc pothook.

Based on above-mentioned, the upper surface of the floor body is provided with multiple anti-skidding raised lines, two neighboring anti-skidding raised line away from From no more than 1cm.

The utility model additionally provides a kind of semi-trailer frame, is laid on the crossbeam including more crossbeams, longitudinal direction Several aluminium section material bottom plates as described above and multiple nylon for being used to connect the crossbeam and the aluminium section material bottom plate Sliding block connector, the cross rail top are provided with the positive T-type boss being laterally extended, and the aluminium section material bottom base plate is provided with The inverted T shaped boss longitudinally extended, the bottom of the nylon slide block connector correspond to the positive T-type boss and are provided with positive T-type groove, The top of the nylon slide block connector corresponds to the inverted T shaped boss and is provided with inverted T-shaped groove.

Based on above-mentioned, multiple lightening holes are offered on the every crossbeam.

The utility model has substantive features and progress compared with the prior art, and specifically, the utility model is described The both ends of floor body are provided with the pin end and the female connector, increase the tortuosity in gap, avoid passing through two and put down Face directly dock and caused by the bad problem of sealing performance, the long rib of L shape of bottom is coated on the short rib of L shape Outside improves leakproofness and humidity resistance；It has the advantages that design science, humidity resistance are good.

Further, the setting of the card slot and the arc pothook facilitates docking by the rotation of pin end, seam The tortuous of gap is also higher, further improves leakproofness and humidity resistance.

Further, the intensive setting of the anti-skidding raised line, improves the non-skid property of sweep.

Further, by the nylon slide block connector, the crossbeam and the aluminium section material bottom plate are facilitated Connection, either aluminum profile crossbeam or steel crossbeam, applicable, not only assembling speed is fast, but also high-quality.

Further, the lightening hole opens up, and alleviates the quality of the crossbeam.
