[0035] Example

[0036] This embodiment provides a curtain wall keel that is easy to disassemble and assemble. Figure 1 As shown, it includes a vertical beam 1 and a horizontal beam 2, one end of the vertical beam 1 is connected to the wall, a pair of the vertical beams 1 are arranged side by side and spaced apart, and a plurality of the horizontal beams 2 are arranged at intervals at the other end of the vertical beam 1; the two ends of the horizontal beam 2 are detachably connected to the vertical beam 1 through a connecting component 3.

[0037] like Figure 2 and Figure 3 As shown, the cross beam 2 includes a first connection portion 21 and a second connection portion 22, a pair of the second connection portions 22 are arranged on both sides of the first connection portion 21, a plug-in plate 23 is provided at the connection between the first connection portion 21 and the vertical beam 1, and the plug-in plate 23 is provided with a first positioning hole 24; a strip opening 11 extending along its axial direction is provided at the corresponding position between the vertical beam 1 and the plug-in plate 23, and the plug-in plate 23 can slide along its axial direction after being inserted into the strip opening 11, and a plurality of second positioning holes 12 are provided along the axial direction between the connection between the vertical beam 1 and the second connection portion 22; a connecting component 3 is arranged at the corresponding position between the second connection portion 22 and the first positioning hole 24, one end of the connecting component 3 passes through the second connection portion 22 and extends into the first positioning hole 24, and the other end thereof is connected to the second connection portion 22 through an elastic member 33; when the vertical beam 1 is connected to the cross beam 2, one end of the connecting component 3 passes through the second positioning hole 12 and the first positioning hole 24 in sequence.

[0038] In this embodiment, the connecting component 3 includes a positioning column 31, a pull plate 32 is provided at one end of the positioning column 31, a through hole is provided at a position corresponding to the second connecting portion 22 and the first positioning hole 24, one end of the positioning column 31 is slidably connected to the through hole, and the pull plate 32 at the other end is fixedly connected to the second connecting portion 22 through an elastic member 33.

[0039] By setting the connecting component 3, after the two vertical beams 1 are installed on the wall, when the horizontal beam 2 is installed, the two pull plates 32 can be pulled to both sides first, and then the plug-in plate 23 on the horizontal beam 2 is inserted into the strip opening 11, and the pull plate 32 is released. At this time, the positioning column 31 can pass through the second positioning hole 12 and the first positioning hole 24 on the plug-in plate 23 in sequence under the action of the elastic member 33, so that the horizontal beam 2 and the vertical beam 1 can be quickly connected. At the same time, when disassembling, it is only necessary to pull the pull plates 32 to both sides to quickly remove the horizontal beam 2, so as to realize quick installation and disassembly.

[0040] In this embodiment, a pair of the vertical beams 1 are provided with an adjustment assembly 4, such as Figure 4 As shown, it includes a square tube 41, which has a through cavity, and fixing plates 44 are provided on both sides of the cavity. The fixing plates 44 are provided with through holes. The square tube 41 is arranged between a pair of vertical beams 1, and a square rod 42 is provided between the square tube 41 and the vertical beam 1. One end of the square rod 42 is fixedly connected to the vertical beam 1, and the other end thereof extends into the square tube 41. The other ends of the pair of square rods 42 are connected to each other through a two-way threaded column 43 passing through the fixing plate 44. The other end of the square rod 42 is provided with a cylindrical thread groove matching the end of the two-way threaded column 43, and the two-way threaded column 43 is screwed together with the square rod 42.

[0041] In this embodiment, the square tube 41 is further provided with a rotating assembly 5 that can rotate the bidirectional threaded column 43, and the rotating assembly 5 includes a rotating rod 51, one end of which extends into the square tube 41 and between a pair of fixing plates 44, and a first bevel gear 52 is connected to the rotating rod 51 extending into the square tube 41, and a second bevel gear 54 meshing with the first bevel gear 52 is fixedly provided at a position corresponding to the bidirectional threaded column 43 and the first bevel gear 52, and a rotating disk 53 is provided at the other end of the square tube 41 to facilitate the rotation of the rotating rod 51. The pair of fixing plates 44 can prevent the first bevel gear 52 and the second bevel gear 54 from being disconnected.

[0042] In this embodiment, the square rods 42 are provided with scale marks to facilitate the control of the spacing when the vertical beams 1 are installed.

[0043] In this embodiment, two ends of one side of the square tube 41 are provided with limiting openings 45, and a limiting slider 46 is provided in the limiting opening 45. One end of the limiting slider 46 is connected to the square rod 42, and the other end thereof extends out of the limiting opening 45. This structure can prevent the square rod 42 from falling out of the square tube 41.

[0044] like Figure 5As shown, an anti-drop assembly 6 is further provided between a pair of vertical beams 1, which includes a position-limiting tube 61, which is provided at the upper and lower sides of the adjustment assembly 4, and a telescopic rod 62 is provided between the position-limiting tube 61 and the vertical beam 1, one end of the telescopic rod 62 is fixedly connected to the vertical beam 1, and the other end thereof extends into the position-limiting tube 61. The length of the telescopic rod 62 is not less than the length of the square rod 42.

[0045] By setting the adjustment component 4, before installing the two vertical beams 1, the rotating rod 51 can be driven to rotate by rotating the rotating disk 53 according to the actual situation of the wall. The rotation of the rotating rod 51 drives the two-way threaded column 43 to rotate under the action of the first bevel gear 52 and the second bevel gear 54. The rotation of the two-way threaded column 43 drives the two square rods 42 to move outward at the same time, so as to adjust the distance between the two vertical beams 1. At the same time, the spacing can be accurately adjusted by observing the scale marks on the square rods 42. Moreover, after adjustment, the stability of the curtain wall keel can be effectively improved under the action of the limit tube 61 and the telescopic rod 62, so that it has the performance of preventing falling off.

[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
