DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0023] A high-strength keel structure, such as Figure 1 as well as Figure 2 As shown, it includes a first keel 1 and a connecting seat 2. A mounting structure is arranged on one side of the first keel 1. The mounting structure includes a connecting block 21 protruding from the connecting seat 2. The connecting block 21 is integrally arranged with the connecting seat 2. A groove 11 is provided on one side of the first keel 1 for the connecting block 21 to be inserted into and installed. At the same time, a first clamping groove 12 is provided on the groove wall adjacent to the groove opening of the groove 11. In addition, a second clamping groove 22 matching the first clamping groove 12 is provided on the connecting block 21. After the connecting block 21 is installed in the groove 11, the first clamping groove 12 and the second clamping groove 22 are combined to form a clamping portion 3, and a clamping member 4 for limiting the connection block 21 from being separated from the groove 11 is provided in the clamping portion 3.

[0024] When the construction personnel need to assemble the keel, they only need to fix the parts to be assembled with the connecting seat 2 by screws or other fixing methods. In this embodiment, the parts to be assembled are the second keel 5. One end of the connecting seat 2 is inserted into the second keel 5 and fixedly connected with the second keel 5 by screws. During installation, the connecting block 21 is inserted into the groove 11. At this time, the first clamping groove 12 and the second clamping groove 22 are combined to form a clamping part 3. Then the clamping part 4 is inserted into the clamping part 3, so that the connecting block 21 and the first keel 1 form a clamping fit. At this time, the assembly operation is completed. With the keel structure of the present invention, the construction personnel can efficiently complete the connection and installation operation by flexibly using the connecting seat 2 when laying out and connecting the keel. In addition, two groups of mounting structures are provided, so two connecting blocks 21 are fixed on the connecting seat 2, and two grooves 11 matching the connecting blocks 21 are also provided on the same side of the first keel 1. In order to further improve the installation adaptability of the keel structure, in the embodiment of the present invention, the number of grooves 11 is provided with 4, and the grooves 11 on the same side are symmetrically arranged with the grooves 11 on the opposite side, so the connecting seat 2 can be installed on any side of the first keel 1 according to actual needs.

[0025] The groove 11 and the first clamping groove 12 are arranged to pass through both ends of the first keel 1. In this way, the connecting seat 2 can be installed at any position in the length direction of the first keel 1, further reflecting the installation adaptability of the keel structure of the present invention and bringing excellent installation efficiency to construction personnel.

[0026] The clamping member 4 includes an expansion portion 41 and a fixing portion 42, wherein the expansion portion 41 includes at least one expansion rod 43. In order to improve the stability of the clamping member 4, in the embodiment of the present invention, four expansion rods 43 are provided. One end of the expansion rod 43 is fixed to the fixing portion 42 and the other end is suspended. A top shaft 44 is connected to the fixing portion 42 through internal threads, and the four expansion rods 43 are evenly distributed around the axial direction of the top shaft 44. In addition, an inclined surface 45 is provided on the inner side of the expansion rod 43, and the inclined surface 45 is on the moving stroke of the top shaft 44. When the top shaft 44 is rotated to move the top shaft 44 toward the expansion rod 43, the top shaft 44 pushes the inclined surface 45 of the expansion rod 43 so that the expansion rod 43 expands outward. At this time, the expansion rod 43 that is continuously expanding outward will gradually abut against the clamping portion 3. The top shaft 44 is continued to be rotated until the expansion rod 43 is tightly pressed against the clamping portion 3. At this time, the installation operation of the clamping member 4 is completed, and the clamping member 4 is tightly pressed against the clamping portion 3, so that the clamping portion 3 and the clamping member 4 produce a large static friction force, thereby limiting the clamping member 4 from being separated from the clamping portion 3, and finally achieving the effect of clamping the connecting seat 2 and the first keel 1.

[0027] Furthermore, in the embodiment of the present invention, the cross section of the clamping part 3 is set in a rectangular shape, and the clamping part 4 is in a rectangular parallelepiped shape as a whole, and the four expansion rods 43 on the clamping part 4 form the four rhombus edges of the rectangular parallelepiped. With such a setting, after the keel structure is installed, during normal use, the clamping part 4 will not rotate in the clamping part 3 due to unexpected circumstances, which can effectively prevent the clamping part 4 from accidentally loosening, making the clamping part 4 more stable during use, and at the same time, it can also be more convenient to rotate the top shaft 44 in the fixing part 42. At the same time, a hexagonal blind hole 46 is provided at one end of the top shaft 44, and the construction personnel can rotate the top shaft 44 with a hexagonal wrench during the installation process, so the installation process of the clamping part 4 can be more convenient and more efficient.

[0028] Specific working process: when assembling the keel, the parts to be assembled are first fixed to the connecting seat 2 by screws or other fixing methods. During installation, the connecting block 21 is installed in the groove 11. At this time, the first clamping groove 12 and the second clamping groove 22 are combined to form the clamping part 3, and then the clamping piece 4 is inserted into the clamping part 3; when the top shaft 44 is located in the fixing part 42, the clamping piece 4 and the clamping part 3 are clearance-matched, and then a hexagonal wrench is used to insert it into the inner hexagonal blind hole 46, and the top shaft 44 is rotated to make the top shaft 44 move in the direction of the expansion rod 43. The top shaft 44 pushes the inclined surface 45 of the expansion rod 43 so that the expansion rod 43 expands outward. At this time, the expansion rod 43 that is continuously expanding outward will gradually abut against the clamping part 3, and the top shaft 44 is continued to be rotated until the expansion rod 43 is pressed tightly against the clamping part 3. At this time, the installation operation of the clamping piece 4 is completed, and the clamping piece 4 is pressed tightly against the clamping part 3, and the connecting seat 2 is clamped with the first keel 1.
