[0010] Further, the hooks at the end parts of the two side plate bodies of the L-shaped keel are respectively bent inward first and then outward.

[0011] Further, the inward bending part of the hooks at the end parts of the two side plate bodies of the L-shaped keel forms an included angle of 60°, and the outward bending part forms an included angle of 115°.

[0012] Alternatively, as another design, the hooks at the ends of the two side plates of the L-shaped keel are first bent inward to form an L shape, which is adapted to the shape of the L-shaped bayonet described above.

[0013] The utility model patent also provides a keel support structure, which includes a plurality of groups of horizontal keels and vertical keels arranged perpendicular to each other. The docking ends of each group of horizontal keels and vertical keels are respectively connected and fixed to the horizontal plate portion and the vertical plate portion of the corner connector described above, and a plurality of corner connectors are connected by clamping with the L-shaped keel described above. The selected L-shaped keel and corner connector are matched with each other.

[0014] Compared with the prior art, the improvements of a corner connector, an L-shaped keel and a keel support structure designed by the utility model patent are as follows: the corner connector and the L-shaped keel form a keel support structure. The corner connector is used for the docking and fixing of horizontal and vertical keels, and the corner connectors are quickly clamped and connected by the L-shaped keel. A card slot is formed on the bottom plate side of the corner connector, which is correspondingly clamped and connected with the hook of the L-shaped keel. The assembly is convenient and fast, and the assembly of the keel can be completed by a single person. The bayonet formed by the card slot of the corner connector is of an inner-wide and outer-narrow structure. The hook of the L-shaped keel is bent twice, and it will not easily come off after being clamped into the bayonet, and the connection is stable. There is no need to use rivets or the like for secondary connection and reinforcement. It is convenient to apply, simple to operate, and the installation of the keel support structure can be completed by a single person, reducing the construction cost. Description of the Drawings
