Background Art

[0002] The large-span stacked glass curtain wall is a novel form of glass curtain wall, and the force requirement of the keel is the overall force mode of the steel frame. The connection of the upper and lower ends has a large span in the height and depth directions. This kind of connection that requires the curtain wall to cross the main body seismic joint needs to have good deformation ability so that the curtain wall will not be damaged and fall off during a medium earthquake.

This lamp device has the characteristics of bright light output, beauty and anti-glare.

[0005] The above mainly focuses on the influence of the curtain wall decoration structure on the decoration effect, but the main body seismic resistance of the large-span glass curtain wall is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0027] A connection structure for a large-span refined steel magic cube stacked curtain wall across the main body seismic joint, as shown in Figure 1 and Figure 2 shown, the connection structure is respectively connected to the side of the main body steel beam and the top of the steel frame, and includes an upper ear plate support 1, a lower ear plate support 2, and a vertical tie rod 3. The upper and lower ear plate supports are used as shaft seats and are axially connected to the vertical tie rod 3. Among them, the upper ear plate support 1 is composed of two special-shaped ear plates and is fixed on the side of the main body steel beam 4; the lower ear plate support 2 is composed of two ear plates and is fixed on the top of the upper cross beam 5 of the steel frame.

[0028] The steel frame 6 of the large-span refined steel magic cube stacked curtain wall is as shown in Figure 2 shown.

[0029] The preferred range of use of the present utility model is that the swing amplitude of the vertical tie rod 3 is: the horizontal distance between the upper and lower axes is not greater than ±80 mm, and the elevation of the lower ear plate support 2 from the horizontal plane is not greater than 8 mm. As shown in Figure 3 and 4 shown.

[0030] In this embodiment, stainless steel bolts with a diameter of φ30 passing through the shaft holes of the upper and lower ear plate supports 1 and 2 are used as pin shafts 7 to connect the vertical tie rods 3.

[0031] A connection method for a connection structure of a large-span refined steel magic cube stacked curtain wall across the main body seismic joint according to the above, is carried out according to the following steps:

[0032] The processing of the upper and lower ear plate supports and the vertical tie rods is completed in the processing factory respectively;

[0033] On the construction site, the upper and lower ear plate supports are welded to the main body steel beam and the top steel cross beam of the steel frame respectively;

[0034] The upper and lower ear plate supports and the vertical tie rods are connected and fixed by using stainless steel bolts with a diameter of φ30 as pin shafts;

[0035] When the main body steel beam at one end of the expansion joint is displaced, it rotates along the tie rod rotating shaft and will not drive the movement of the stacked glass curtain wall keel, without damaging the curtain wall itself and the connection structure of the present invention.

[0036] The present invention relates to a connection structure and method for a large-span refined steel magic cube stacked curtain wall across the main body seismic joint. The keel of the large-span refined steel magic cube stacked glass curtain wall is formed by welding a rectangular refined steel with equal-strength combination of steel plates, and the stacked form with orderly entry and exit and height is completed. The steel frame 6 is integrally located on the first-floor civil structure, and the upper end is fixedly connected by the rotatable joint rotating shaft tie rod of the present invention to form an overall stress mode. There is no structural connection at the second-floor level in the height direction, and it is directly connected by a tie rod at the third-floor position. The span between the bottom connection point and the upper connection point with orderly entry and exit is relatively large. The first-floor structure is the basic structure without a seismic expansion joint, and the upper end is connected below the connecting corridor civil structure with a seismic joint in the third-floor main structure, resulting in the connection and fixation of the overall steel frame across the expansion joint. To meet the requirement that the curtain wall is not damaged under the seismic deformation condition, the connection of the joint rotating shaft tie rod at the upper end is particularly important.

[0037] The above description of this embodiment is only for explaining the present invention, and is not limited to the technical solutions described in the present invention. Various components in the present invention can be modified or equivalently replaced to achieve the same process technical effect; as long as the use requirements are met, they are all within the protection scope of the present invention.
