[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0033] Example
[0034] like Figure 1 As shown, the utility model proposes a high-performance building composite keel, including a first bracket 1 and a second bracket 2 for support, a socket 11 for passing the second bracket 2 is provided in the first bracket 1, the second bracket 2 is plugged with the first bracket 1 through the socket 11, and a limiting hole 21 is provided on the second bracket 2. The figure only shows a part of the keel, and the overall keel should include a plurality of first brackets 1 and a plurality of second brackets 2 arranged in an alternating manner. Since it is necessary to highlight the features in this scheme, only a part is shown. The first bracket 1 and the second bracket 2 are made of a polymer compound polyurethane material. Polyurethane has the characteristics of low temperature resistance, aging resistance, and high hardness, so that the keel has a certain strength. At the same time, during the construction or decoration process, when the polyurethane keel is no longer needed, it can be recycled. After recycling, it can be reprocessed to make new polyurethane products or recycle energy to achieve the purpose of effective resource utilization.
[0035] Further, such as Figure 2-4As shown, the above-mentioned keel includes a limiting assembly 3 for positioning the second bracket 2, and the limiting assembly 3 is arranged in the first bracket 1. The limiting assembly 3 includes four groups of fixed rods 31 fixedly connected in the first bracket 1, and the ends of the four groups of fixed rods 31 away from the first bracket 1 are commonly fixedly connected with a fixing ring 32, and the fixing rods 31 fix the position of the fixing ring 32. A limiting rod 33 is slidably connected in the fixing ring 32, and the fixing ring 32 is used to limit the limiting rod 33. The limiting rod 33 is made of carbon fiber material, and the hardness of the limiting rod 33 is high and not easy to bend. The limiting rod 33 passes through the limiting hole 21, and a limiting ring 34 is fixedly connected to the limiting rod 33, and the limiting ring 34 is fitted with the fixing ring 32. The limiting ring 34 is used to limit the distance of movement of the limiting rod 33, so that the limiting rod 33 makes the limiting ring 34 and the fixing ring 32 close after the movement, and the limiting rod 33 is in a proper position. The outer ring of the limiting rod 33 is also fixedly connected to a plurality of limiting blocks 35, and the number of the limiting blocks 35 corresponds to the second bracket 2. The limiting blocks 35 are located in the limiting holes 21, and the limiting blocks 35 rotate synchronously with the limiting rod 33, and after the limiting rod 33 rotates, the limiting blocks 35 are driven to be stuck in the second bracket 2. Fixed blocks 36 are installed on both sides of the limiting blocks 35, and the outer diameter of the fixed blocks 36 is equal to the width of the limiting hole 21. The fixed blocks 36 are used to be stuck in the limiting hole 21 to limit the second bracket 2.
[0036] Furthermore, the keel further comprises a positioning assembly 4 for cooperating with the limiting assembly 3 to further fix the position of the second bracket 2, and the positioning assembly 4 is installed at one end of the limiting assembly 3. The positioning assembly 4 comprises a connecting column 41 fixedly connected to the end of the limiting rod 33 away from the fixing ring 32, the connecting column 41 is rectangular, the end of the connecting column 41 away from the limiting rod 33 is fixedly connected to the first limiting plate 42, and the connecting column 41 is also slidably connected to the rotating rod 43, the rotating rod 43 will not rotate when sliding, and at the same time, the connecting column 41 is driven to rotate synchronously when the rotating rod 43 rotates. A groove 44 corresponding to the rotating rod 43 is provided at one end of the first bracket 1 close to the rotating rod 43, and the setting of the groove 44 is convenient for accommodating the rotating rod 43. The outer ring of the limiting rod 33 is also fixedly connected to a limiting ring 45, and the limiting ring 45 is arranged at one end of the limiting rod 33 close to the connecting column 41, and the limiting ring 45 is used to limit the rotating rod 43 to prevent the rotating rod 43 from moving to the outer ring of the limiting rod 33. A fixed shaft 46 is installed at both ends of the rotating rod 43, and a second limiting plate 47 is fixedly connected to one end of the fixed shaft 46 away from the rotating rod 43. A positioning plate 48 is sleeved on the outer ring of the fixed shaft 46, and the positioning plate 48 rotates around the fixed shaft 46. A positioning hole 49 is provided on the positioning plate 48 and the first bracket 1. The position of the positioning plate 48 is fixed by installing a bolt in the positioning hole 49, thereby fixing the position of the rotating rod 43.
[0037] In this embodiment, the second bracket 2 is first inserted into the first bracket 1 through the insertion hole 11, and then the limiting rod 33 is passed through the limiting hole 21, so that one end of the limiting rod 33 slides into the fixing ring 32, and the limiting block 35 is located in the limiting hole 21, and the fixing block 36 is also located in the limiting hole 21, and the limiting ring 34 is in contact with the fixing ring 32. At this time, the rotating rod 43 is rotated 90 degrees, and the rotating rod 43 drives the limiting rod 33 to rotate synchronously through the connecting column 41, so that the limiting block 35 fixedly connected to the limiting rod 33 rotates 90 degrees synchronously, and the limiting block 35 is stuck in the second bracket 2. At this time, the rotating rod 43 changes from a horizontal state to a vertical state, and the rotating rod 43 is pushed so that the rotating rod 43 slides on the connecting column 41 and approaches the limiting ring 45, and the rotating rod 43 enters the groove 44. Then, the two sets of positioning plates 48 are rotated 180 degrees, so that the positioning plates 48 overlap with the positioning holes 49 opened on the first bracket 1. At this time, the positioning plates 48 can be fixed to the first bracket 1 by bolts, so that the position of the rotating rod 43 is fixed. At the same time, the limiting rod 33 is fixed between the rotating rod 43 and the fixing ring 32 and cannot move, so that the second bracket 2 cannot be withdrawn from the first bracket 1 and is firmly fixed.
[0038] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
