[0028] Such as Figure 1 And Figure 4As shown in the figure, the present utility model provides a curtain wall connection system, which includes a connecting plate 2, a positioning mechanism, a curtain wall column 1 and a secondary keel 4. The connecting plate 2 has two side plates 21 perpendicular to each other, and the two side plates 21 can be respectively installed on two perpendicular surfaces of a concrete column 9. A positioning mechanism is provided on the side of the side plate 21 facing away from the concrete column 9; the positioning mechanism includes two positioning plates 3, and the positioning plate 3 includes a horizontal plate 31 and a vertical plate 32 perpendicular to each other. The horizontal plate 31 is attached to and fixedly connected to the side of the side plate 21 facing away from the concrete column 9, and the vertical plate 32 is connected to the side of the horizontal plate 31. The vertical plate 32 is perpendicular to the side plate 21; the vertical plates 32 of the two positioning plates 3 are horizontally spaced apart and a vertically extending column installation area 33 is formed therebetween. An outward-turning plate 321 is provided on the side of the vertical plate 32 facing away from the concrete column 9; in the direction from the horizontal plate 31 to the vertical plate 32, the distance between the two outward-turning plates 321 gradually increases, and the minimum distance between the two outward-turning plates 321 is equal to the width of the column installation area 33. And a curtain wall column 1, a part of the curtain wall column 1 is inserted into the column installation area 33, the curtain wall column 1 extends vertically and is in close contact with the vertical plate 32; another part of the curtain wall column 1 is located outside the column installation area 33 and is fixedly connected with a secondary keel 4 for installing the curtain wall. The curtain wall column 1 is connected to the two vertical plates 32 through a plurality of bolt and nut assemblies 5.

[0029] Specifically, the vertical lengths of the horizontal plate 31, the vertical plate 32 and the outward-turning plate 321 are all 0.9 - 1.1 times the vertical length of the curtain wall column 1.

[0030] In this embodiment, first, the connecting plate 2 and the positioning mechanism are installed. After they are installed, the two side plates 21 can respectively fit on two mutually perpendicular surfaces of the concrete column 9. The transverse plate 31 fits and is fixedly connected to the side of the side plate 21 facing away from the concrete column 9. The vertical plate 32 is connected to the side of the transverse plate 31. The vertical plate 32 is perpendicular to the side plate 21, and the vertical plates 32 of the two positioning plates 3 are horizontally spaced apart and a vertically extending column installation area 33 is formed therebetween. This column installation area 33 is used to install the curtain wall column 1. Outward-turning plates 321 are provided on both vertical plates 32, and in the direction from the transverse plate 31 to the vertical plate 32, the distance between the two outward-turning plates 321 gradually increases, and the minimum distance between the two outward-turning plates 321 is equal to the distance between the two vertical plates 32. Then the curtain wall column 1 is installed. Since the width between the two outward-turning plates 321 is large, when installing the curtain wall column 1, workers do not need to use a lot of force to make the curtain wall column 1 enter the space between the two outward-turning plates 321. Further, the two outward-turning plates 321 play a guiding role, facilitating the construction personnel to push the curtain wall column 1 into the column installation area 33. When the curtain wall column 1 completely enters the column installation area 33, a plurality of bolt-nut assemblies 5 are used to fixedly connect the curtain wall column 1 and the positioning mechanism. Therefore, setting the outward-turning plates on the vertical plates 32 can facilitate the workers to install the curtain wall column 1 in the column installation area 33 of the positioning mechanism, thereby overcoming the problem that it is difficult to install the curtain wall column 1 due to manufacturing errors and other reasons, reducing the installation difficulty, and improving the installation efficiency.

[0031] As Figure 5 shown, in some embodiments of the present utility model, a plurality of sleeves 51 are provided on the side of one of the vertical plates 32 facing away from the curtain wall column 1. The plurality of sleeves 51 correspond one-to-one to the plurality of bolt-nut assemblies 5, and the sleeves 51 are provided with limit holes. The bolt-nut assembly 5 includes a fastening bolt 54 and a nut 55. The rod portion of the fastening bolt 54 passes through the two vertical plates 32 and the curtain wall column 1. The head of the fastening bolt 54 is movably embedded in the limit hole. The limit hole is arranged to limit the rotation of the head of the fastening bolt 54. The nut 55 is threadedly connected to the rod portion of the fastening bolt 54, and the nut 55 presses against the side of the other vertical plate 32 facing away from the curtain wall column 1.

[0032] Specifically, after the curtain wall column 1 is installed in the column installation area 33, the curtain wall column 1 corresponds one-to-one to the threaded holes on the positioning mechanism. The fastening bolt 54 is inserted into the threaded hole of the curtain wall column 1 from the threaded hole of one vertical plate 32 and passes through the threaded hole of the other vertical plate 32. The nut 55 is tightened on the tail of the fastening bolt 54. When the nut 55 is tightened, since the head of the fastening bolt 54 is restricted by the sleeve 51, the fastening bolt 54 will not rotate due to the rotation of the nut 55, and the construction personnel do not need to hold the nut 55 with one hand and fix the head of the fastening bolt 54 with the other hand.

[0033] In some embodiments of the present utility model, the thickness of the sleeve 51 is 1.2 - 1.5 times the thickness of the head of the fastening bolt 54; and / or, an elastic cushion layer is provided on the inner wall of the limiting hole, the elastic cushion layer surrounds the head of the fastening bolt 54, and the elastic cushion layer is clamped between the head of the fastening bolt 54 and the inner wall of the limiting hole.

[0034] Specifically, in order to enable the sleeve 51 to fully restrict the rotation of the fastening bolt 54, the thickness of the sleeve 51 is made greater than the thickness of the head of the fastening bolt 54, and the optimal thickness of the sleeve 51 is between 1.2 - 1.5 times the thickness of the head of the fastening bolt 54. At the same time, when the nut 55 is turned, the fastening bolt 54 will inevitably have a slight rotation, but due to the limitation of the limiting hole, the fastening bolt 54 presses against the inner wall of the limiting hole and cannot rotate. In order to prevent the fastening bolt 54 from damaging the limiting hole and its own head, an elastic cushion layer is provided on the inner wall of the limiting hole.

[0035] As Figure 6 shown, in some embodiments of the present utility model, a plurality of cushion blocks 52 are fixedly connected to the side of one of the vertical plates 32 facing away from the curtain wall column 1. The plurality of cushion blocks 52 respectively correspond to a plurality of bolt - nut assemblies 5. The cushion block 52 is provided with a threaded hole; the bolt - nut assembly 5 includes a fastening bolt 54 and a nut 55. The rod portion of the fastening bolt 54 passes through the two vertical plates 32 and the curtain wall column 1, and the rod portion of the fastening bolt 54 is threadedly connected to the threaded hole; the nut 55 is threadedly connected to the rod portion of the fastening bolt 54, and the nut 55 contacts the side of the cushion block 52 facing away from the curtain wall column 1; the head of the fastening bolt 54 presses against the side of the other vertical plate 32 facing away from the curtain wall column 1.

[0036] Specifically, after the curtain wall column 1 is installed in the column installation area 33, the curtain wall column 1 corresponds to the threaded holes on the positioning mechanism one by one. The fastening bolt 54 is inserted into the threaded hole of the curtain wall column 1 from the threaded hole of one vertical plate 32 and passes through the threaded hole of the other vertical plate 32. Then, the construction worker rotates the fastening bolt 54 so that the fastening bolt 54 is threadedly connected to the cushion block 52. When the head of the fastening bolt 54 presses against the side of the other vertical plate 32 facing away from the curtain wall column 1, the nut 55 is installed at the tail of the fastening bolt 54, and the nut 55 is tightened so that the nut 55 contacts the cushion block 52. The threaded connection between the fastening bolt 54 and the cushion block 52 can fixedly connect the curtain wall column 1 and the positioning mechanism; the nut 55 is closely attached to the cushion block 52 and connected to the fastening bolt 54, playing a role in preventing loosening.

[0037] Preferably, the thickness of the cushion block 52 is less than the thickness of the nut 55.

[0038] In some embodiments of the present utility model, in order to improve the tightness and stability of the bolt connection, an elastic gasket 53 is provided between the head of the fastening bolt 54 and the vertical plate 32 in contact therewith.

[0039] In some embodiments of the utility model, the two side surfaces of the curtain wall column 1 clamped by the positioning mechanism are respectively provided with limit blocks 6, the side of the limit block 6 facing the positioning mechanism is pressed against the outer flap 321, and the side of the limit block 6 facing away from the positioning mechanism is pressed against the inner side surface of the secondary keel 4.

[0040] Specifically, when the curtain wall column 1 is pushed into the column installation area 33, after the threaded hole of the curtain wall column 1 is aligned with the threaded hole of the positioning mechanism, the limit blocks 6 on both sides of the curtain wall column 1 are pressed against the outer surface of the outer flap 321 of the positioning mechanism, thereby limiting the position of the curtain wall column 1 in the column installation area 33, making it easier for the fastening bolts 54 to pass through the threaded holes.

[0041] In some embodiments of the present invention, a limiting mechanism 7 is provided in the column installation area 33 , and the limiting mechanism 7 is pressed against the side of the curtain wall column 1 facing the connecting plate 2 .

[0042] Specifically, when the curtain wall column 1 is pushed into the column installation area 33, after the threaded hole of the curtain wall column 1 is aligned with the threaded hole of the positioning mechanism, the limiting mechanism 7 can press against the side of the curtain wall column 1 facing the connecting plate 2, thereby preventing the curtain wall column 1 from continuing to move toward the cross plate 31.

[0043] In some embodiments of the utility model, the limiting mechanism 7 includes two limiting plates; a connecting portion 71 is provided on one side of the limiting plate, and the connecting portions 71 of the two limiting plates are respectively connected in parallel with the two vertical plates 32, and the other sides of the two limiting plates are connected to each other so that the limiting mechanism 7 is formed into a V shape; and the connecting parts of the two limiting plates are pressed against the side of the curtain wall column 1 facing the connecting plate 2.

[0044] Specifically, the connection parts 71 at one end of the two limit plates are parallel to the two vertical plates 32, and the two limit plates are respectively connected to the inner side surfaces of the respective adjacent vertical plates 32. The other ends of the two limit plates close to the curtain wall column 1 are arched toward the curtain wall column 1 and connected to each other to form a V shape, pressing against the side of the curtain wall column 1 facing the connection plate 2, thereby limiting the installation position of the curtain wall column 1 in the column installation area 33.

[0045] like Figure 2 As shown, in some embodiments of the present invention, two hanging blocks 8 are provided on the top of the curtain wall column 1 , and the bottom surfaces of the two hanging blocks 8 are in contact with the top sides of the two vertical plates 32 respectively.

[0046] Specifically, when installing the curtain wall column 1 , during the preparation work, the construction workers can hang the curtain wall column 1 on the top of the vertical plate 32 through the hanging block 8 provided on the top of the curtain wall column 1 , so as to temporarily position the curtain wall column 1 .

[0047] It should be noted that when the hanging block 8 is hung on the top of the vertical plate 32, the threaded hole of the curtain wall column 1 and the threaded hole on the corresponding positioning mechanism have their axes on the same horizontal plane.

[0048] like Figure 3 As shown, in some embodiments of the utility model, the hanging block 8 is provided with a vertical through hole, and the latch 81 is inserted into the through hole from the top of the hanging block 8 and the rod of the latch 81 contacts the outer side of the vertical plate 32. Specifically, in some cases, the hands of the on-site workers may suddenly temporarily detach from the curtain wall column 1, for example, because of dust in the eyes that needs to be dealt with immediately, or for example, a sharp thorn is pierced into the palm. When the curtain wall column 1 enters the column installation area 33, the construction personnel can insert the latch 81 into the through hole of the hanging block 8, so that the rod of the latch 81 contacts the outer side of the vertical plate 32. When the worker's hands suddenly detach from the curtain wall column 1 and cause it to fall in the direction of the back of the horizontal plate 31, the outer flap 321 will limit the movement of the latch 81, thereby preventing the curtain wall column 1 from falling. Therefore, the latch 81 provided on the hanging block 8 can prevent the curtain wall column 1 from suddenly falling in the absence of the support of the worker, thereby preventing the danger from occurring.

[0049] The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0050] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0051] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
