Detailed Description
The structure and features of the present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that various modifications can be made to the embodiments disclosed herein, and therefore, the embodiments disclosed in the specification should not be construed as limiting the present invention, but merely as exemplifications of embodiments thereof, which are intended to make the features of the present invention obvious.
The unit curtain wall system is formed by hanging, assembling, splicing and assembling curtain wall unit plates processed by a factory on site, each curtain wall unit plate is composed of an aluminum section frame and a panel material installed on the aluminum section frame, and the panel material is generally plane glass or plane stone. The aluminum profile frame is formed by fixedly connecting an upper cross beam, a lower cross beam, a male upright post and a female upright post through screws, and the upper layer curtain wall unit plate and the lower layer curtain wall unit plate are connected with each other through the splicing of the upper cross beam and the lower cross beam; the left and right curtain wall unit plates on the same layer are connected with each other through the male upright post and the female upright post in an inserting way.
Because the manufacturing process of the curtain wall unit plate panel (especially glass) for manufacturing the curved surface is complex and the manufacturing cost is high, for the curved surface unit curtain wall system with concave-convex staggered joints, the curved surface unit curtain wall system is actually formed by splicing and assembling flat curtain wall unit plates. The invention improves the curtain wall unit plate, so that the upper and lower curtain wall unit plates can be mutually spliced to form the concave-convex staggered curved unit curtain wall system.
The curtain wall unit plate block forming the concave-convex staggered joint curved surface unit curtain wall system comprises an aluminum profile frame and a panel material arranged on the aluminum profile frame, wherein the aluminum profile frame is formed by splicing a transition conversion cross beam, a lower cross beam, a male column and a female column through screws.
As shown in fig. 1-4, the transition conversion beam is composed of a beam 1, a pi-shaped water tank 2 and a U-shaped connecting groove 3. The crossbeam 1, the left and right male stand columns, the female stand columns and the lower crossbeam are spliced into an aluminum profile frame through screws, and the pi-shaped water tank 2 is fixed on the crossbeam 1.
In order to insert the lower cross beam of the upper curtain wall unit plate which is not in the same vertical plane and has concave-convex staggered joints into the transition conversion cross beam at the top of the lower curtain wall unit plate, as shown in the figure, the invention cuts off the pi-shaped water tank 2 at the connecting part 21 of the pi-shaped water tank 2 corresponding to the two adjacent curtain wall unit plates at the upper layer, cuts off the pi-shaped water tank 2 at the connecting part 22 of the pi-shaped water tank 2 corresponding to the two adjacent curtain wall unit plates at the lower layer, and fixes the cut-off multi-section pi-shaped water tanks on the cross beam 1 in the directions of inserting, screwing and the like sequentially, sequentially and tightly matching with the upper curtain wall unit plate; welding two sections of Pi-shaped water tanks at the turning joint together through aluminum alloy to ensure no gap; meanwhile, a U-shaped connecting groove 3 is arranged in a bent seam of the connected and fixed Pi-shaped water tank, and sealant is filled between the outer wall of the U-shaped connecting groove 3 and the inner wall of the Pi-shaped water tank 2, so that the spliced Pi-shaped water tank is guaranteed to have good sealing and water-proof performance.
The invention cuts the Pi-shaped water tank 2 into a plurality of sections, fits a curve with the trend matched with the upper layer curtain wall unit plate in sequence and then fixes the sections on the cross beam 1, and then inserts the lower cross beam of the upper layer curtain wall unit plate into the Pi-shaped water tank of the transition conversion cross beam at the top of the lower layer curtain wall unit plate, thereby mutually inserting and fixing the curtain wall units with the staggered joints of the upper and the lower concave convex to form the curved surface curtain wall system with the staggered joints of the concave and the convex. The pi-shaped water tank 2 plays a role in supporting up and down and connecting the upper layer curtain wall unit plate and the lower layer curtain wall unit plate on one hand, and the pi-shaped water tank 2 also plays a role in draining water on the other hand. As shown in the figure, the pi-shaped water tank is also provided with a plurality of drain holes 23 which are communicated with a drain cavity 56 (see figures 7 and 9) formed by the male stand column and the female stand column, so that a small amount of rainwater entering the pi-shaped water tank can be drained outdoors through the drain cavity in time, and the drainage problem is solved.
In order to form a curved curtain wall system with concave-convex staggered joints, the Pi-shaped water tank 2 is cut into a plurality of sections, and the connecting strength of the Pi-shaped water tank is reduced because the Pi-shaped water tank is cut into the plurality of sections, so that a U-shaped connecting groove 3 is arranged in a joint of the Pi-shaped water tank 2 through sealant, the U-shaped connecting groove 3 is arranged in a turning joint of the Pi-shaped water tank 2 as a lock pin, the U-shaped connecting groove 3 mainly plays roles in transition of the Pi-shaped water tank of a curtain wall unit plate and transmission of wind load of an upper layer plate, particularly in the turning joint of the Pi-shaped water tank (namely the joint of two upper layer plates), and meanwhile, the U-shaped connecting groove 3 also plays roles in strengthening the strength and the reinforcement of the joint of the Pi-shaped water tank.
The Pi-shaped water tank forming the transition conversion cross beam is designed and lofted by a three-dimensional entity, is cut into at least two sections according to the trend of an upper layer curtain wall unit plate, respectively penetrates into a cross beam clamping groove of the transition conversion cross beam, then the two sections of the Pi-shaped water tank are reliably welded together according to a splicing angle simulated by a computer by an aluminum alloy welding process so as to ensure the accurate positioning of the upper layer plate, the front end of the Pi-shaped water tank is clamped into the clamping groove of the cross beam of the transition conversion cross beam, the rear end of the Pi-shaped water tank is connected with the cross beam of the transition conversion cross beam through a stainless steel bolt, and then the two sides of the transition conversion cross beam are reliably connected with a vertical unit frame assembly.
In addition, the Pi-shaped water tank 2 and the cross beam 1 which form the transitional conversion cross beam are not in rigid connection, three waterproof lines are formed between the two through arranging adhesive tapes, and the front end and the rear end of the transitional conversion cross beam are subjected to adhesive applying treatment to form a plurality of waterproof lines. The joint of the turning of the pi-shaped water channel is welded by adopting aluminum alloy, the joint of the two sections of the pi-shaped water channels is ensured to have no gap, the waterproof performance of the transition conversion beam is ensured to be good, and layered drainage is adopted, namely rainwater sliding along the glass curtain wall panel is discharged outdoors in a hidden drainage mode through the No. 2 cavity and the No. 3 cavity of the male stand column and the female stand column on the two sides of the curtain wall unit plate.
Fig. 5 is a schematic longitudinal sectional structure view of the transition conversion beam of the curtain wall unit plate block. Because the radius of each layer of curved surface of the concave-convex stagger joint curved surface unit curtain wall system is different, the upper layer curtain wall unit plate and the lower layer curtain wall unit plate are possibly not in the same vertical plane, as shown in figure 5, the upper layer curtain wall unit plate A protrudes out of the lower layer curtain wall unit plate B, during installation, the lower cross beam 4 of the upper layer curtain wall unit plate A is inserted into the pi-shaped water channel 2 of the transition cross beam of the lower layer curtain wall unit plate B, and therefore the upper layer and the lower layer of concave-convex stagger joint curtain wall unit plates are spliced together.
When the concave-convex stagger joint of the upper curtain wall unit plate and the lower curtain wall unit plate along the height direction is not obvious, as shown in fig. 6, the upper curtain wall unit plate A and the lower curtain wall unit plate B are inserted and connected with each other along the inclined surface profile at a certain angle, and the arc effect of the curved surface profile is realized by fitting the curved surface. In order to ensure that the upper layer curtain wall unit plate A and the lower layer curtain wall unit plate B are better inserted and connected along the fitting of the curved surface, the fixed angle of the Pi-shaped water channel 2 of the lower layer unit plate transition conversion cross beam is adjusted, so that the lower cross beam of the upper layer unit plate and the lower cross beam of the upper layer unit plate are assembled and connected according to a certain insertion angle, and the smooth installation of the upper layer curtain wall unit plate and the lower layer curtain wall unit plate is ensured.
The unit curtain wall system with the concave-convex staggered joint curved surface model solves the problems of irregular staggered joint connection, sealing and drainage among unit plates of the upper curtain wall and the lower curtain wall in different layers, and also realizes a flat plate broken line fitting curved surface and an arc effect.
As shown in fig. 7, the unit panels a and B of the curtain wall of the same layer constituting the curved unit curtain wall system of the invention are connected with each other by the male vertical posts 5 and the female vertical posts 6. The male upright post 5 and the female upright post 6 are both aluminum profiles or plastic steel profiles which are formed in one step by injection molding. The male upright post 5 is divided into three cavities by reinforcing ribs, and the three cavities are divided into a cavity 1, a cavity 2, a cavity 52 and a cavity 3 from the outside to the inside in sequence; similarly, the female upright 6 is also divided into three chambers by the reinforcing ribs, and divided into a No. 1 chamber 61, a No. 2 chamber 62 and a No. 3 chamber 63 in the order from the outside to the inside.
When a mould of the male upright post 5 is arranged, the angle between the rib 54 of the male upright post 5 inserted into the female upright post 6 and the horizontal plane is 172-178 degrees, so that when curtain wall unit plates on the same layer are mutually spliced, curved surface unit curtain wall systems with the horizontal angle of 175 +/-3 degrees can be formed by selecting and matching the male upright post curtain wall unit plates with different horizontal angles and mutually splicing the curtain wall unit plates.
As shown in fig. 7, when the rib 54 of the male upright post inserted into the female upright post is inserted into the curtain wall unit plate block horizontally forming an included angle of 172 degrees to 178 degrees, a gap 7 with a width of 15mm ± 2mm is formed between the male upright post 5 and the female upright post 6 at the end part of one side of the adjacent curtain wall unit plate block close to the outdoor side, and in order to ensure the waterproofness and the sealing performance of the whole curtain wall unit system, an elastic compressible adhesive tape 8 needs to be filled in the gap 7, so that no gap exists between the two adjacent curtain wall unit plate blocks.
Because the male upright post 5 and the female upright post 6 of the curtain wall unit plate comprise three cavities, when a unit curtain wall system with a concave-convex shape is required to be formed, as shown in fig. 8 and 9, the cavity (namely, cavity No. 1) at the outdoor side of the male upright post or the female upright post of one adjacent curtain wall unit plate is cut off, so that the male upright post and the female upright post of the two adjacent curtain wall unit plates form section sizes with different thicknesses, and then a glass panel is installed, so that the unit curtain wall system with the concave-convex shape of the adjacent curtain wall unit plates on the same layer is formed. As shown in fig. 8 and 9, in the embodiment of the present invention, the female upright 6 of the curtain wall unit plate D is cut off near the outdoor cavity No. 1, and only the cavity No. 2 and the cavity No. 3 are reserved, so that the male upright 5 of the adjacent curtain wall unit plate C and the female upright 6 of the curtain wall unit plate D form a thickness difference, and then the whole frame of the curtain wall unit plate is provided with the fixed glass panel 9; and finally, the male stand column and the female stand column are inserted to form the concave-convex staggered shape of the unit plates of the adjacent curtain walls on the same layer.
For aesthetic reasons, decorative strips 10 and profiles 11 for fixing the decorative strips may also be added to the surface of the unitized curtain wall system.
When a concave-convex staggered curved surface unit curtain wall system is laid, concave-convex dislocation between adjacent curtain wall unit plate blocks on the same layer is realized, and concave-convex dislocation between an upper surface plate and a lower surface plate of the same curtain wall unit plate block is also realized sometimes.
Since the male upright post 5 and the female upright post 6 of the curtain wall unit plate block comprise three cavities, when the concave-convex dislocation modeling between the upper panel and the lower panel of the same curtain wall unit plate block is required to be formed, as shown in fig. 10-12, at the curtain wall unit plate block frame which is required to form the concave-convex effect, the cavities 51 and 61 of the male upright post 5 and the female upright post 6 at two sides close to the outdoor side are simultaneously milled and cut off (as shown in fig. 11), so that the thickness of the positions of the male upright post 5 and the female upright post 6 is thinned, the cavities 2 and 3 are reserved, and then, another glass panel 9 is installed and fixed on the side wall of the cavity 2 of the male upright post and the female upright post which are cut off the cavity 1, so that the concave-convex dislocation effect of the same curtain wall unit plate block is formed, wherein the convex-concave effect is that the convex-concave effect is E (see.

The curtain wall unit plates forming the invention adopt the design of a transition conversion beam and a Pi-shaped water tank, the Pi-shaped water tank is cut off at the joint of two adjacent curtain wall unit plates on the upper layer and the joint of two adjacent curtain wall unit plates on the lower layer, and then a plurality of sections of the Pi-shaped water tank which are cut off are fitted into a curve according to the sequence and the trend matched with the curtain wall unit plates on the upper layer and fixed on the beam, thereby the curtain wall units with the staggered joints of the upper and the lower concave and convex parts are mutually spliced and fixed to form a curved curtain wall system with the staggered joints of the concave and the convex parts, and the vertical surface effect of the fitting curved surface of the irregular staggered joint broken lines of the curtain wall unit.
In addition, the invention adopts aluminum alloy welding at the turning joint of the Pi-shaped water channel of the transition conversion beam of the curtain wall unit plate and solves the problem of sealing and water proofing of the broken line fitting curved surface fissure of displacement unit curtain wall by the design of embedding the U-shaped connecting groove in the sealant.
In addition, the pi-shaped water tank is provided with a drain hole, rainwater flowing down along the glass panel is drained through a drain cavity formed by the male and female stand columns, and the drainage problem of the concave-convex curved surface unit curtain wall system is solved.
2. Because the angle between the ribs for splicing the male upright post and the female upright post of the curtain wall unit plate block and the horizontal plane is 172-178 degrees, the invention can realize the vertical plane effect of the flat fitting circular arc between the curtain wall unit plate blocks on the same layer.
3. The male upright post and the female upright post which form the curtain wall unit plate block comprise three cavities, and concave-convex dislocation between adjacent curtain wall unit plate blocks on the same layer and between the upper surface plate and the lower surface plate of the same curtain wall unit plate block are implemented by cutting the cavity cavities of the male upright post and the female upright post which are close to the outside.
