[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] For specific implementation: see Figure 1-4A keel structure of an external wall panel comprises at least one horizontally arranged first transverse keel 1, and a plurality of second transverse keels 2 which are located above or below the first transverse keel 1 and are horizontally arranged and distributed along a vertical interval, wherein the first transverse keel 1 and the second transverse keel 2 are located on the same facade, and both ends of the first transverse keel 1 and the second transverse keel 2 are respectively fixedly connected to the building facade structure through mounting supports. In this embodiment, the building facade structure is two columns with a large column spacing, wherein a plurality of adjustment rods 3 are distributed between adjacent second transverse keels 2 and between adjacent first transverse keels 1 and second transverse keels 2, and the vertical spacing between adjacent second transverse keels 2 and between adjacent first transverse keels 1 and second transverse keels 2 can be adjusted by the adjustment rods 3.

[0020] Specifically, in this embodiment, the first transverse keel 1 is a rectangular steel tube with relatively large bending rigidity. At the same time, in order to further improve the rigidity of the first transverse keel 1, the first transverse keel 1 includes two first transverse keels 1 arranged at intervals, and a reinforcement structure is provided between the two first transverse keels 1. The two first transverse keels 1 are connected into a whole through the reinforcement structure. The reinforcement structure includes a plurality of support rods 4 made of C-shaped channel steel, and the two ends of the support rods 4 are respectively connected to the two first transverse keels 1. The reinforcement structure also includes a diagonal brace 5 arranged between adjacent support rods 4, and the two ends of the diagonal brace 5 are respectively connected to the two first transverse keels 1. For the portion with a larger span between the two first transverse keels 1, an adjustment rod 3 can also be provided to adjust the horizontality of the two first transverse keels 1.

[0021] The second transverse keel 2 is a thin-walled steel plate with low bending rigidity and light weight, and its cross section is L-shaped, S-shaped or C-shaped.

[0022] Both ends of the adjusting rod 3 are provided with external threads. Correspondingly, a connecting seat 6 is provided on the lower side of the first transverse keel 1. One end of the adjusting rod 3 is connected to the connecting seat 6 through a nut 7. A through hole is provided on the second transverse keel 2. One end of the adjusting rod 3 passes through the through hole and is connected to the second transverse keel 2 through a nut 7.

[0023] During implementation, according to the load condition of the keel, a first transverse keel 1 can be arranged at a certain height to ensure that the first transverse keel 1 can withstand the bending stress of the second transverse keel 2 below or above, and at the same time, according to actual needs, whether to use a single or multiple first transverse keels 1 can be selected to form a frame structure with higher rigidity to ensure the bearing capacity and stability of the entire keel structure.

[0024] The present application sets a first transverse keel with greater bending rigidity and a second transverse keel with less bending rigidity and lighter weight below it, and the transverse keels are adjustably connected by adjusting the tie rod, so that the first transverse keel bears the bending stress of the second transverse keel below and the weight of the external wallboard installed on the transverse keel, and the horizontality of the second transverse keel can be conveniently adjusted by adjusting the tie rod, thereby improving the installation quality of the wallboard and reducing the installation requirements. At the same time, the present application only uses transverse keels, and only has an adjusting tie rod vertically, so the amount of steel used is small, the weight is light, and the economy is better.
