[0012] (3) Beneficial effects

[0013] Compared with the prior art, the present invention provides an assembled structural column head connector with the following beneficial effects:

[0014] The assembled structural column head connector pushes the positioning frame so that the two positioning seats on the positioning frame are inserted into the empty slots on the two steel beams in turn, and then the screw is rotated. Through the action of the threaded structure, the positioning seats can be tightened in the empty slots, so that the blocking blocks will not shake in the empty slots, thereby limiting the positioning frame at the joint of the two steel beams. This process does not require drilling of the vertical beams and the horizontal beams. It is not only simple to operate, but also can ensure the strength of the vertical beams and the horizontal beams. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 , an assembled structural column head connector of the present invention includes a steel beam 1 and a positioning frame 2, the steel beam 1 is provided with an empty slot 3, the positioning frame 2 is provided with a plurality of connecting components, the connecting components include a screw 8, a guide rod 9 and a positioning seat 4, the positioning seat 4 can be inserted into the interior of the empty slot 3, and two cavities 5 are symmetrically arranged on the positioning seat 4, a spring 7 is provided inside the cavity 5, one end of the spring 7 is provided with a block 6, the two blocks 6 are respectively located on both sides of the empty slot 3, and the block 6 can limit the positioning seat 4 in the empty slot 3, the guide rod 9 passes through the positioning frame 2 and connects the two ends of the positioning seat 4, the screw 8 passes through the positioning frame 2 and is inserted into the interior of the positioning seat 4, and the screw 8 is threadedly connected to the positioning seat 4;

[0022] In this embodiment, first, a pressure is applied to the positioning frame 2 so that the positioning seat 4 enters the empty slot 3. At this time, the spring 7 can provide an elastic force to the clamping block 6, so that the two clamping blocks 6 can limit the positioning seat 4 in the empty slot 3 (the cross section of the empty slot 3 is T-shaped, and the cross section of the clamping block 6 is a right-angled trapezoid). At this time, the clamping block 6 can swing up and down in the empty slot 3, further pushing the positioning frame 2 so that the positioning frame 2 slides on one of the steel beams 1, and then the other positioning seat 4 is inserted into the empty slot 3 on the other steel beam 1, as shown in FIG. Figure 1 As shown, at this time, the positioning frame 2 can position the joint end of the two steel beams 1, and then the screw 8 is rotated. Through the action of the threaded structure, the positioning seat 4 can be tightened in the empty slot 3, and the clamping block 6 can be prevented from shaking in the empty slot 3, thereby limiting the positioning frame 2 at the joint of the two steel beams 1. This process does not require drilling of the vertical beams and the horizontal beams, which is not only simple to operate, but also can ensure the strength of the vertical beams and the horizontal beams.

[0023] In this embodiment, the two connecting components have the same size.

[0024] In this embodiment, the block 6 adopts a right-angled trapezoidal structure. Figure 3 As shown, when the clamping block 6 enters the empty slot 3 , since its top is a plane, it can limit the positioning seat 4 and prevent the positioning seat 4 from leaving the empty slot 3 .

[0025] In this embodiment, the bottom end of the guide rod 9 is threadedly connected to the positioning seat 4. When the positioning frame 2 needs to be temporarily disassembled, the screw 8 and the guide rod 9 are rotated to remove the screw 8 and the guide rod 9 from the positioning frame 2. At this time, the positioning frame 2 will be detached from the positioning seat 4, making it easy to disassemble the positioning frame 2.

[0026] In this structure, the positioning frame 2 is an L-shaped structure. The positioning frame 2 and the connecting components are made of aluminum alloy. Aluminum alloy has the advantages of high strength and strong corrosion resistance, which can make the positioning frame 2 and the connecting components not easily damaged.
