Examples
Fig. 1 is a schematic structural view of a curtain wall building ceiling structure 010 in an embodiment of the invention; fig. 2 is an enlarged view of fig. 1 at a. Referring to fig. 1 and 2 (mainly, see fig. 2), the curtain wall building suspended ceiling structure 010 of the present embodiment includes an upper floor 200 and a lower ceiling 300. A ceiling space Q1 is defined between the upper floor 200 and the lower ceiling 300, and may be used to provide desired piping and equipment. The ceiling space Q1 may also be provided with a horizontal fire barrier 420 and a vertical fire barrier 410. Wherein the vertical fire barrier 410 is provided outside the upper floor 200 and the lower ceiling 300. The upper and lower edges of the vertical fire barrier 410 may be coupled to upper and lower cross frame members 600, respectively, which serve as a mount for the curtain wall glass panel 500. Generally, the cross frame beam 600 may be made of aluminum alloy.
In order to avoid that various devices or components (such as the vertical fire-proof partition 410 and the like) in the ceiling space Q1 can be seen outside the curtain wall to affect the appearance of the building curtain wall, the curtain wall back plate structure 100 is arranged between the two transverse frame beams 600 as a barrier in the present embodiment, specifically, the lower end face of the upper transverse frame beam 600 is used as the upper mounting face P1 of the curtain wall back plate structure 100, and the upper end face of the lower transverse frame beam 600 is used as the lower mounting face P2 of the curtain wall back plate structure 100. Thus, the control of the appearance effect of the curtain wall can be conveniently realized by designing the curtain wall back plate structure 100. In this embodiment, the curtain wall back plate structure 100 is attached to the outer side of the vertical fire barrier 410, so as to improve the horizontal rigidity of the curtain wall back plate structure 100.
Fig. 3 is a schematic view of an installation structure of a curtain wall backboard structure 100 in an embodiment of the invention. Referring to fig. 3, the curtain wall back plate structure 100 of the present embodiment includes a panel 10, an upper connecting structure 20, and a lower connecting structure 30. The upper side of the panel 10 is connected to the upper installation surface P1 by the upper connection structure 20. The lower connecting structure 30 is connected to the lower mounting surface P2 and has a fitting groove C1 with an upward opening. The lower edge of the panel 10 is fitted into the fitting groove C1, and the lower edge of the panel 10 and the groove bottom surface P5 of the fitting groove C1 are spaced from each other to form a vertical gap f0 that allows a vertical relative displacement of the whole of the panel 10 and the upper attachment structure 20 connected with each other with respect to the lower attachment structure 30.
As described above, the curtain wall back plate structure 100 according to the embodiment of the present invention is mainly used to block the spaces of the upper floor 200 and the lower ceiling 300, so that only the outer surface of the panel 10 can be seen from the outside of the curtain wall of the building, and the structure inside the suspended ceiling can not be seen, thereby facilitating the design of the appearance of the building.
In the curtain wall backboard structure 100 in this embodiment, the upper edge of the panel 10 is connected to the upper fixing member through the upper connecting structure 20, the lower edge of the panel 10 is fitted into the fitting groove C1 with the upward opening of the lower connecting structure 30, and a vertical gap f0 exists between the lower edge of the panel 10 and the groove bottom surface P5 of the fitting groove C1, instead of fixedly connecting the lower edge of the panel 10 to the lower connecting structure 30, so that the panel 10 is suspended in a fixed manner, and a person has a degree of freedom of vertical displacement. Under the structure, the panel 10 can be vertically displaced, so that the error of the structure size is within a larger allowable range; in addition, the vertical gap f0 also has the function of an expansion joint, that is, when the curtain wall is subjected to a load (thermal expansion and cold contraction deformation load or other loads) to cause vertical relative displacement between the upper mounting surface P1 and the lower mounting surface P2, the panel 10 can be adaptively displaced, and the panel 10, the upper connecting structure 20 or the lower connecting structure 30 cannot be damaged.
The upper connecting structure 20 in this embodiment may be designed in various forms. For example, referring to fig. 4, the upper connecting structure 20 in the present embodiment includes a first connecting member 21 and a first covering member 22. The upper edge of the panel 10 is connected to the upper mounting surface P1 by a first connector 21, and the first connector 21 is located on the rear surface side of the panel 10. The first connecting member 21 has a first engaging edge 21a. The upper edge and the first engaging edge 21a of the panel 10 are spaced from the upper mounting surface P1 by a first gap f1. The first cover 22 has a second engaging edge 22a configured to be able to be caught in the first gap f1 and to be located between the upper mounting surface P1 and the first engaging end D1 of the first engaging edge 21a. Optionally, the first engaging end D1 has a first wedge surface P3 obliquely intersecting with the snapping-in direction of the first cover 22. The second engagement edge 22a of the first cover 22 has a first wedge T1 corresponding to the first wedge surface P3. The first engaging edge 21a is of an elastic structure, so that when the first engaging edge 21a is engaged, the first wedge T1 can elastically push the first engaging edge 21a open and be engaged in the first gap f1. Alternatively, the first link 21 is riveted to the upper edge of the panel 10 by a rivet L1. The first covering member 22 has a first covering edge 22b perpendicular to the second engaging edge 22a, and the first covering edge 22b is located outside the panel 10 and covers the rivet L1 to prevent the rivet L1 from being exposed to the outside.
The lower coupling structure 30 in this embodiment may be designed in various forms. For example, referring to fig. 5, the lower connecting structure 30 in the present embodiment includes a second connecting member 31 and a second covering member 32. The second connector 31 is connected to the lower mounting surface P2 and is located on the rear surface side of the panel 10. The second cover 32 is engaged with the second connector 31 and defines a fitting groove C1 with an upward opening in cooperation with the second connector 31. Optionally, the second connector 31 has a third engagement edge 31a. The third engaging edge 31a and the lower edge of the panel 10 are spaced apart from the lower attachment surface P2 by a second gap f2. The second cover 32 has a fourth engaging edge 32a configured to be able to be engaged into the second gap f2 and to be engaged between the lower mounting surface P2 and the second engaging end D2 of the third engaging edge 31a. The upper surface of the fourth engaging side 32a constitutes a groove bottom surface P5 of the engaging groove C1. Optionally, the second covering element 32 has a second covering edge 32b perpendicular to the fourth engaging edge 32a thereof, the second covering edge 32b being located outside the panel 10. The second link member 31 has a side restriction edge 31b spaced opposite to the second covering edge 32b and defining the fitting groove C1. Optionally, the side of the third engaging edge 31a away from the fourth engaging edge 32a extends upward to form a side limiting edge 31b. Optionally, the width of the panel 10 is smaller than the width of the mating groove C1, so that the panel 10 has a certain lateral gap in addition to the vertical gap f0, and when the upper mounting surface P1 and the lower mounting surface P2 are relatively displaced, the panel 10 can also be laterally displaced in addition to the vertical adaptive displacement, thereby further avoiding the panel 10, the upper connecting structure 20, and the lower connecting structure 30 from being damaged by stress.
The mounting manner of the curtain wall backboard structure 100 in this embodiment will be described.
With reference to fig. 2, 3, 4 and 5, the curtain wall back plate structure 100 in the present embodiment may be installed according to the following steps:
