[0033] See also Figures 1 to 6 , the present invention provides a technical solution:

[0034] Embodiment 1

[0035] A curtain wall keel unit comprises: a keel pre-assembly unit 1 and a connecting piece 6.

[0036] Specifically, the keel pre-assembly unit 1 includes an assembly column 2, and the inner cavities at the upper and lower ends of the assembly column 2 are respectively provided with limit stops 3 and plug-in columns 4, and the plug-in columns 4 are plugged with the assembly columns 2. When two vertically adjacent keel pre-assembly units 1 are spliced, the plug-in columns 4 can be inserted into the inner cavities of the lower assembly columns 2, and rely on gravity to ensure the stable connection of the two keel pre-assembly units 1, and the two keel pre-assembly units 1 are placed in a horizontal direction. The side of the assembly column 2 is fixedly installed with an assembly beam 5;

[0037] Secondly, the connecting member 6 is located at the end of the assembled cross beam 5. The connecting member 6 includes a connecting frame 7 which is in a "C" shape with an opening facing downwards. Both side surfaces of the connecting frame 7 are inclined outwards, and the edge of the connecting frame 7 is folded outwards to form a buckling portion 8. The buckling portion 8 is in a "C" shape with an opening facing upwards and buckles on the side edge of the assembled cross beam 5. When two horizontally adjacent keel pre-assembly units 1 are spliced, the connecting member 6 can fixedly connect two adjacent assembled cross beams 5, thereby strengthening the entire curtain wall keel. The buckling portion 8 buckles on the edge of the assembled cross beam 5 from bottom to top, which can improve the connection stability between the two assembled cross beams 5.

[0038] Embodiment 2

[0039] On the basis of Embodiment 1, in order to reduce the installation process, the present application is provided with four assembled cross beams 5, and the four assembled cross beams 5 are respectively located at the upper and lower ends of both side surfaces of the assembled column 2. The assembled cross beam 5 is perpendicular to the assembled column 2. The assembled column 2 and the assembled cross beam 5 can be pre-assembled on the ground to reduce the operation steps of high-altitude connection and reduce the installation process.

[0040] Embodiment 3

[0041] On the basis of Embodiment 2, in order to improve the connection stability between the two assembled cross beams 5, the present application further has a U-shaped connecting frame 9 provided inside the connecting frame 7. An adjustment slot hole 10 is provided on the surface of the connecting frame 7. The end of the U-shaped connecting frame 9 penetrates through the adjustment slot hole 10 and tightens and fixes two adjacent assembled cross beams 5. An elastic cushion block 11 is padded between the surface of the connecting frame 7 and the inner wall of the assembled cross beam 5. The elastic cushion block 11 is fixedly bonded to the connecting frame 7. The U-shaped connecting frame 9 sequentially penetrates through the connecting frame 7 and the assembled cross beam 5 from bottom to top, ensuring that the connection between the two assembled cross beams 5 is more convenient and stable. Since both side surfaces of the connecting frame 7 are inclined, when the U-shaped connecting frame 9 presses the connecting frame 7 upwards, both side surfaces of the connecting frame 7 can contract inwards. At this time, the buckling portion 8 buckles on the edge of the assembled cross beam 5, which can prevent the side of the assembled cross beam 5 from deforming outwards and affecting the connection stability between the two assembled cross beams 5.

[0042] Embodiment 4

[0043] On the basis of Embodiment 3, in order to fix the U-shaped connecting frame 9, the present application further has a pressing plate 12 tightly attached to the surface of the assembled cross beam 5. The pressing plate 12 is sleeved on the outer side of the end of the U-shaped connecting frame 9 and is pressed and fixed by a fastening nut 13. The pressing plate 12 and the fastening nut 13 are used to fix the U-shaped connecting frame 9 to prevent the U-shaped connecting frame 9 from detaching.

[0044] Embodiment 5

[0045] On the basis of the fourth embodiment, in order to pre-fix the connection between the assembled crossbeam 5 and the assembled column 2, the present application also has a pre-connected angle steel 14 provided at one end of the assembled crossbeam 5 close to the assembled column 2, and the top and side surfaces of the pre-connected angle steel 14 are provided with positioning holes 15, and the end surface of the assembled crossbeam 5 is provided with a waist hole 16. The pre-connected angle steel 14 and the assembled crossbeam 5 are fixedly connected by bolts, so that the assembled crossbeam 5 and the assembled column 2 can be pre-connected and fixed on the ground.

[0046] Embodiment 6

[0047] On the basis of Example 5, in order to fix the pre-connected angle steel 14 to the side of the assembled column 2, the present application also has a reinforcing plate 17 fixedly arranged on the inner side of the pre-connected angle steel 14 to reinforce the strength of the pre-connected angle steel 14 itself, and a tensioning bolt 18 is provided through the interior of the assembled column 2, and the two ends of the tensioning bolt 18 respectively fix the two pre-connected angle steels 14, thereby fixing the pre-connected angle steel 14 to the side of the assembled column 2.

[0048] Embodiment 7

[0049] On the basis of Example 6, in order to install the limit stop 3, the limit stop 3 of the present application is set to a hollow structure, and a clamping slot 19 is opened through the side of the limit stop 3. The limit stop 3 is buckled on the outside of the tightening bolt 18 from top to bottom through the clamping slot 19. A limiting protrusion 20 is set in the middle of the clamping slot 19, and a guide chamfer 21 is set at the lower end opening of the clamping slot 19. Therefore, the limit stop 3 can be stably installed in the upper end inner cavity of the assembly column 2 under the action of gravity. The setting of the limiting protrusion 20 is used to prevent the limit stop 3 from being easily separated from the tightening bolt 18, and the setting of the guide chamfer 21 ensures that the limit stop 3 can be easily buckled on the outside of the tightening bolt 18 through the clamping slot 19.

[0050] Embodiment 8

[0051] On the basis of the seventh embodiment, in order to prevent the curtain wall glass from being damaged, the present application also has a mounting boss 22 fixedly arranged on the back of the assembled column 2, the mounting boss 22 is fixedly connected to the building wall, and wear-resistant rubber strips 23 that fit the curtain wall are arranged on both sides of the mounting boss 2, thereby preventing the curtain wall glass from being squeezed and collided by the assembled column 2 and causing damage.

[0052] Embodiment 9

[0053] On the basis of Example 8, in order to splice the entire curtain wall keel, the present application is provided with multiple keel pre-assembly units 1, and the two vertically adjacent keel pre-assembly units 1 are maintained in plug-in connection through the plug-in column 4, and the two horizontally adjacent keel pre-assembly units 1 are maintained in fixed connection through the connecting piece 6, so as to splice the entire curtain wall keel.

[0054] The present invention also discloses a pre-assembly construction method according to the above-mentioned curtain wall keel unit, which specifically comprises the following steps:

[0055] Step 1: Assemble the keel pre-assembly unit 1 on the ground, fix the pre-connected angle steel 14 to the side of the assembled column 2 by the tightening bolts 18, and fix the plug-in column 4 to the lower end of the assembled column 2 by the tightening bolts 18, and then fix the assembled crossbeam 5 to the pre-connected angle steel 14 to ensure that the assembled crossbeam 5 and the assembled column 2 are fixedly connected, and the limit block 3 is placed from top to bottom into the inner cavity of the upper end of the assembled column 2 under the action of gravity, and buckled on the outside of the tightening bolts 18;

[0056] Step 2: hoist the keel pre-assembly unit 1 to the required height, and fix the two adjacent assembly beams 5 through the connecting piece 6, wherein the buckle 8 at the edge of the connecting frame 7 can be buckled on the edge of the assembly beam 5 to improve the stability of the connection between the two assembly beams 5, so that the two horizontally adjacent keel pre-assembly units 1 can be spliced ​​together, and the two vertically adjacent keel pre-assembly units 1 can be plug-in connected through the plug-in column 4 and kept fixed under the action of gravity.
