Obviously, the following drawings are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0025] Figure 1 FIG. shows a front sectional structural schematic diagram of an earthquake-resistant structure of a sloped daylighting roof glass curtain wall according to an embodiment of the present invention.

[0026] Figure 2 FIG. shows Figure 1 a partial enlarged structural schematic diagram at A in DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following illustrates the embodiments of the present invention through specific specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0028] The following further describes the present invention in detail with reference to the drawings and specific embodiments. In the drawings, the horizontal direction is the horizontal transverse direction, the direction perpendicular to the drawing is the horizontal longitudinal direction, and the vertical direction in the drawings is the vertical direction.

[0029] As Figure 1-2As shown in the figure, the seismic structure of the slope daylighting roof glass curtain wall according to the embodiment of the present invention includes: a main beam 6, a vertical glass curtain wall 3, a steel structure beam 1, a slope daylighting roof glass curtain wall, and a seismic deformation structure 9.

[0030] The vertical glass curtain wall 3 is fixedly connected to the main beam 6 and extends downward in the direction of the main beam 6. In this embodiment, a vertically extending curtain wall support keel 51 is fixedly provided on the outer surface of the main beam 6, and the vertical glass curtain wall 3 is fixedly provided on the side of the vertically extending curtain wall support keel 51 away from the main beam 6. Among them, a plurality of embedded parts are fixedly provided on the outer surface of the main beam 6, and the vertically extending curtain wall support keel 51 is fixedly connected to the main beam 6 through the embedded parts, and the vertically extending curtain wall support keel 51 is connected to the embedded parts through structural members such as bolts. Among them, the vertical glass curtain wall 3 is installed at a position below the lower surface of the main beam 6 of the vertically extending curtain wall support keel 51.

[0031] The steel structure beam 1 is movably arranged above the main beam 6 and projects outside the main beam 6 and the vertical glass curtain wall 3. A sliding support 7 arranged above the main beam 6 is fixedly provided on the lower surface of the steel structure beam 1 through a pier, and the steel structure beam 1 is enabled to move horizontally on the main beam 6 through the sliding support 7. Further, the slope daylighting roof glass curtain wall includes a first top surface glass curtain wall 21 and a second top surface glass curtain wall 22 connected at a certain angle. One end of the first top surface glass curtain wall 21 connected to the second top surface glass curtain wall 22 is installed downwardly above the steel structure beam 1, and the second top surface glass curtain wall 22 is installed at the end position where the steel structure beam 1 extends outside the main beam 6 and the vertical glass curtain wall 3. In this embodiment, the second top surface glass curtain wall 22 is arranged parallel to the vertical glass curtain wall 3. Based on the above structure, the first top surface glass curtain wall 21 and the second top surface glass curtain wall 22 constituting the slope daylighting roof glass curtain wall are installed on the steel structure beam 1, and the vertical glass curtain wall 3 is installed on the main beam 6. And since the steel structure beam 1 is movably installed on the main beam 6 through the sliding support 7, the slope daylighting roof glass curtain wall and the vertical glass curtain wall 3 are installed as relatively independent structures, so that Figure 1 and Figure 2 in the horizontal longitudinal direction, there is a space for seismic deformation between the slope daylighting roof glass curtain wall and the vertical glass curtain wall 3.

[0032] Further, a first top surface support keel 41 fixedly connected to the steel structure beam 1 is provided on the lower surface of the first top surface glass curtain wall 21. A second top surface support keel 43 is provided inside the second top surface glass curtain wall 22, and a plurality of top surface curtain wall secondary keels 42 are connected between the second top surface support keel 43 and the steel structure beam 1 to increase the stability of the second top surface glass curtain wall 22 through the plurality of top surface curtain wall secondary keels 42.

[0033] To increase the drainage performance, a gutter 8 with an upward opening is formed at the connection between the first top glass curtain wall 21 and the second top glass curtain wall 22, and a drain pipe is connected to the bottom of the gutter 8.

[0034] The seismic deformation structure 9 is installed between the second top glass curtain wall 22 and the vertical glass curtain wall 3. The seismic deformation structure 9 includes a first bottom plate 91 connected to the second top glass curtain wall 22 and a second bottom plate 92 located above the first bottom plate 91 and connected to the vertical glass curtain wall 3. A flexible plate 11 connected to the second top glass curtain wall 22 is fixedly provided at one end of the second bottom plate 92 away from the vertical glass curtain wall 3. Since the first bottom plate 91 and the second bottom plate 92 are arranged in a staggered manner, the first bottom plate 91 and the second bottom plate 92 do not affect the horizontal and transverse structural deformation in the view such as Figure 1 or Figure 2 between the vertical glass curtain wall 3 and the second top glass curtain wall 22. And under the action of the flexible plate 11 with telescopic performance, while ensuring the tightness between the vertical glass curtain wall 3 and the second top glass curtain wall 22, the seismic deformation effect is not affected.

[0035] Based on the above, the sloping roof daylighting glass curtain wall and the vertical glass curtain wall are respectively independently attached and installed on the steel structure beam or the main beam, and the two independent curtain wall structures are connected by the seismic deformation structure composed of the bottom plate and the flexible plate, so that when the roof truss undergoes large deformation during an earthquake, the sloping roof daylighting glass curtain wall and the vertical glass curtain wall can adapt to the seismic deformation without damage.

[0036] Furthermore, as Figure 1 shown, the vertical glass curtain wall 3 is installed at a position below the lower surface of the main beam 6 of the vertical curtain wall support keel 51. The second bottom plate 92 is installed at the top end of the vertical glass curtain wall 3 and abuts against the vertical curtain wall support keel 51. As Figure 2 shown, a horizontally longitudinally arranged connecting keel 53 is fixedly provided on the upper surface of one end of the second bottom plate 92 away from the vertical glass curtain wall 3. A plurality of vertical curtain wall secondary keels 52 arranged obliquely or transversely are connected between the connecting keel 53 and the vertical curtain wall support keel 51 to increase the stability of the second bottom plate 92. As Figure 2 shown, the first bottom plate 91 is installed at the bottom of the second top glass curtain wall 22 and extends towards the vertical glass curtain wall 3, and the upper surface of the end of the first bottom plate 91 close to the second top glass curtain wall 22 is fixedly connected to the second top support keel 43 through fasteners such as bolts. Among them, as Figure 2As shown in the second bottom plate 92, the second bottom plate 92 has a two-layer stepped structure, and the upper sections of the first bottom plate 91 and the second bottom plate 92 are arranged in a staggered manner, so that the bottom surface of the first bottom plate 91 and the bottom surface of the lower section of the second bottom plate 92 are unified, making the bottom surface structure more beautiful and having better water-proof performance. Among them, the flexible plate 11 is a rubber plate in the shape of a bellows. The left end of the rubber plate is fixedly connected to the second top surface support keel 43 through structural parts such as bolts, and the other end is clamped and installed between the second bottom plate 92 and the connecting keel 53 through structural parts such as bolts.

[0037] More preferably, to increase the heat insulation performance, heat insulation layers 10 are provided on the bottom surface of the eaves gutter 8, the inner side of the second top surface glass curtain wall 22, the inner side of the first top surface glass curtain wall 21, the upper side of the flexible plate 11, the upper side of the second bottom plate 92, and the side of the main beam 6 close to the vertical glass curtain wall 3. In this embodiment, the heat insulation layer 10 is made of rock wool heat insulation board.
