[0031] The following further describes in detail a convex upper crossbar structure for the step difference of a building curtain wall unit proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. According to the following description and the claims, the advantages and features of the present invention will be clearer.

[0032] Refer to Figure 1 and Figure 2 , in an embodiment, a convex upper crossbar structure for the step difference of a building curtain wall unit includes a fixed upper crossbar 1, a moving upper crossbar 2, a plurality of first fasteners 3 and a plurality of second fasteners 4. It is set that the direction from the indoor to the outdoor of the curtain wall unit 7 is the first direction.

[0033] Among them, the fixed upper crossbar 1 is provided at the top of the main frame of the curtain wall unit 7. The moving upper crossbar 2 is movably arranged on the fixed upper crossbar 1 along the first direction, that is, it can slide on the fixed upper crossbar 1 along the first direction.

[0034] A number of first fasteners 3 are provided at both ends of the movable upper crossbar 2 and fasten the movable upper crossbar 2 and the fixed upper crossbar 1, which are used to fasten the relative positions of the movable upper crossbar 2 and the fixed upper crossbar 1 and bear forces. A number of second fasteners 4 are evenly distributed on the movable upper crossbar 2 and fasten the movable upper crossbar 2 and the fixed upper crossbar 1, which are used to maintain the stability between the movable upper crossbar 2 and the fixed upper crossbar 1.

[0035] In this embodiment, the upper crossbar above the main frame of the curtain wall unit body 7 is divided into a fixed upper crossbar 1 and a movable upper crossbar 2. The movable upper crossbar 2 can move on the fixed upper crossbar 1, and the relative positions between the movable upper crossbar 2 and the fixed upper crossbar 1 are fastened by the first fasteners 3 and the second fasteners 4. During installation, the curtain wall unit body 7 with the fixed upper crossbar 1 can be installed on the building keel first, and then the movable upper crossbar 2 can be installed on the fixed upper crossbar 1 according to the step difference requirements. By adopting the method of moving the movable upper crossbar 2 later, the step difference requirements of the upper layer curtain wall unit body 7 can be adapted, and the problem that the upper crossbar of the existing curtain wall unit body 7 cannot adapt to the building step difference is solved.

[0036] At the same time, by splitting into the fixed upper crossbar 1 and the movable upper crossbar 2 in the above way, the standardization of the two is realized, factory batch processing is achieved, production efficiency and processing quality are improved, the product matching is good, and the product performance is enhanced at the same time.

[0037] The following further describes the specific structure of the convex upper crossbar structure for the step difference of the building curtain wall unit body in this embodiment:

[0038] In this embodiment, a nail groove is provided on the fixed upper crossbar 1, which is used to position the relative positions of the movable upper crossbar 2 and the fixed upper crossbar 1 to adapt to different step difference requirements, so that the movable upper crossbar 2 and the fixed upper crossbar 1 are accurately positioned and combined. Of course, in other embodiments, it may not be a nail groove, and only a mark provided on the fixed upper crossbar 1 is required to realize the positioning between the movable upper crossbar 2 and the fixed upper crossbar 1, which is not specifically limited here.

[0039] Furthermore, the upper surface of the fixed upper crossbar 1 is a fixed frame with a thickened treatment. The thickness of the fixed frame can be 5 mm, which can be specifically set according to actual requirements. The increase in thickness can ensure stable force and avoid situations such as damage to the fixed frame due to insufficient structural strength.

[0040] Refer to Figure 2 , in this embodiment, when the fixed frame is 5 mm, the first fastener 3 can be a stainless steel bolt M8X25 mm, and the second fastener 4 is a stainless steel machine screw M5X15 mm. Specifically, two groups of stainless steel bolts M8X25 mm can be respectively set at both ends of the movable upper crossbar 2, with four in each group; and M5X15 mm can be evenly distributed in several groups along the length direction of the movable upper crossbar 2, with two in each group.

[0041] Since the force and force transmission of the upper horizontal mainly occur at both ends, the first fasteners 3 are provided to fasten both ends of the movable upper horizontal 2 to the fixed upper horizontal 1 respectively, so that the force from the upper curtain wall unit 8 above can be transmitted to the main frame of the curtain wall unit 7 through both ends of the movable upper horizontal 2, ensuring the stability and continuity of the force. The second fasteners 4 evenly distributed on the movable upper horizontal 2 make the connection between the movable upper horizontal 2 and the fixed upper horizontal 1 closer and more stable, while ensuring the stability of the force.

[0042] In this embodiment, the surface facing the outside is set as the front end, and the surface facing the inside is set as the rear end. A first waterproof line is provided on the fixed upper horizontal 1. A decorative frame 5 is provided at the front end of the movable upper horizontal 2. The decorative frame 5 is adhesively bonded to the fixed upper horizontal 1 and forms a second waterproof line. Further, the decorative frame 5 can be a fluorocarbon sprayed aluminum single plate.

[0043] To solve the drainage problem at the cross joint position of the stepped unit body, the exposed fluorocarbon sprayed aluminum single plate is fixed to the front end of the movable upper horizontal 2 through stainless steel screws, thus not damaging the first waterproof line of the fixed upper horizontal 1, and the second waterproof line of the curtain wall unit 7 can be realized by caulking, thereby improving the waterproof performance of the curtain wall unit 7. At the same time, the drainage line of the stepped unit body is realized by the combination of the exposed fluorocarbon sprayed aluminum single plate and the fixing on the movable upper horizontal 2. At the construction site, according to the conventional caulking method for the cross joint of the unit body and the sealing of the aluminum water deflector at the cross joint position, the drainage line problem of the curtain wall unit 7 is solved.

[0044] Regarding the setting of the last waterproof layer for the small amount of rainwater entering the inner cavity of the unit body in the stepped unit body, this is a difficult point in the design of this embodiment. To solve the drainage problem of the upper curtain wall unit 8 at the cross joint position, at the cross joint position, the waterproof member provided at the rear end of the movable upper horizontal 2 is inserted into the upper end of the adjacent curtain wall unit 7 that has been installed on this floor, thereby realizing the third waterproof line in the inner cavity of the unit body. Specifically, the waterproof member can be a 2mm closed aluminum single plate.

[0045] To ensure the thermal insulation and energy-saving performance of the curtain wall unit 7, in this embodiment, in the design of the stepped unit body, the combination of the exposed fluorocarbon sprayed aluminum single plate and the thermal insulation member 6 is used to enhance the thermal performance of the stepped unit body itself. Through thermal software analysis, it meets the design requirements. Among them, the thermal insulation member 6 can be a thermal insulation board.

[0046] According to the conventional unit body, at the cross joint position of the unit body, the airtightness of the upper end of the unit body is closed through the upper cross frame of the unit body. However, for the stepped curtain wall unit 7, it cannot be normally closed through the upper cross frame. To solve the airtightness problem of the curtain wall unit 7, in this embodiment, a sealing plate is provided at the front ends of the movable upper horizontal 2 and the fixed upper horizontal 1 to realize the airtightness closure of the upper end of the curtain wall unit 7. The sealing plate can be a 1.5mm sealing aluminum single plate.

[0047] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, provided that these changes fall within the scope of the claims of the present invention and equivalent technologies, they still fall within the protection scope of the present invention.
