Description

Technical Field

[0001] The present invention belongs to the technical field of aluminum single - panel curtain walls, and particularly relates to an aluminum single - panel curtain wall with a function of compensating for thermal expansion and contraction. Background Technique

[0002] An aluminum single - panel curtain wall is a new type of curtain wall material that uses high - quality aluminum alloy plates as the base material, and is formed through technologies such as numerical control bending, and a decorative coating is sprayed on the surface. The structure of the curtain wall aluminum single - panel mainly consists of components such as a panel, a reinforcing rib, and an angle code.

[0003] The common existing installation method of aluminum single - panels is to fix the aluminum single - panels on the keel through angle codes. This fixing method is not applicable in areas with large temperature differences between day and night. Since the keel steel frame is directly fixed to the building, the deformation amount during thermal expansion and contraction is small, but the aluminum single - panels installed on the keel frame have thermal expansion and contraction amplitudes both horizontally and vertically. Over time, the aluminum single - panels will deform, and the service life will be greatly reduced. Summary of the Invention

[0004] The purpose of the present invention is to provide an aluminum single - panel curtain wall with a function of compensating for thermal expansion and contraction in order to solve the above - mentioned problems.

[0005] The present invention achieves the above - mentioned purpose through the following technical solutions:

[0006] An aluminum single - panel curtain wall with a function of compensating for thermal expansion and contraction, including a keel steel frame, an aluminum plate main body with a back edge fixed on the keel steel frame through a fixing structure, and a decorative strip assembly arranged between the gaps of adjacent aluminum plate main bodies. The fixing structure includes an angle code fixedly connected to the keel steel frame and an inclined plate fixedly connected to the end of the angle code. An inclined sliding groove is formed on the surface of the inclined plate, and the aluminum plate main body is slidably connected to the inclined sliding groove through a fixing component;

[0007] Among them, the fixing component includes a sliding rod located inside the inclined sliding groove, a front trapezoidal block and a rear trapezoidal block respectively located on both sides of the sliding rod for clamping the inclined plate, and a threaded rod connected to the front trapezoidal block for fixing the aluminum plate main body.

[0008] As a further optimized solution of the present invention, the cross - section of the keel steel frame is in a square - shaped opening, and the angle code is fixedly connected to the keel steel frame through bolts, which is convenient for disassembly and assembly.

[0009] As a further optimized solution of the present invention, all the aluminum plate main bodies in each horizontal row are supported by two mutually parallel keel steel frames, and this setting can leave space for installing the decorative strip assembly.

[0010] As a further optimized solution of the present invention, the rear trapezoidal block and the end of the sliding rod are detachably installed. A slot corresponding to the sliding rod is provided on the inclined surface of the rear trapezoidal block, and a fixing bolt that is threadedly and fixedly connected to the end of the sliding rod is penetrated through the surface of the rear trapezoidal block, which facilitates the disassembly and assembly of the rear trapezoidal block.

[0011] As a further optimized solution of the present invention, reinforcing ribs are provided between the back edge and the main aluminum plate body. Thread grooves corresponding to the threaded rods are provided on the back surface of the back edge. The back edge is used for fixing, and the reinforcing ribs provided at the back edge are used to prevent the back edge from bending and deforming.

[0012] As a further optimized solution of the present invention, the inclination direction of the inclined plate is the thermal expansion direction of the main aluminum plate body at this point. Each main aluminum plate body has four fixing structures, and the inclined plates in each fixing structure are arranged according to the thermal expansion direction. Therefore, the inclination directions of the four inclined plates are radially outward, leaving both space for thermal expansion and contraction, and the reserved space will not cause the main aluminum plate body to shake.

[0013] As a further optimized solution of the present invention, the decorative strip assembly includes a decorative strip main body and two chute blocks provided on the back surface of the decorative strip main body. The opening directions of the two chute blocks are opposite. An L-shaped plate that is slidably connected is provided inside the chute block. A number of clamping rods are provided at the ends of the two L-shaped plates. Card slots corresponding to the clamping rods are provided on the surface of the back edge. A spring is also provided between the two L-shaped plates. In order to increase the aesthetics between the gaps of the main aluminum plate body, a decorative strip assembly with a compensation structure is provided, so that the decorative strip can adapt to the thermal expansion and contraction of the main aluminum plate body.

[0014] As a further optimized solution of the present invention, a slideway is formed at the gap between the two chute blocks. A magnetic slide bar is slidably arranged in the slideway. Hinge rods are hinged between the side surface of the magnetic slide bar and the surfaces of the two L-shaped plates, which facilitates the disassembly and assembly of the decorative strip assembly.

[0015] As a further optimized solution of the present invention, an elastic right-angle pad is provided at the docking part between the decorative strip main body and the adjacent decorative strip main body, which is beneficial to the aesthetics of the interface.

[0016] The beneficial effects of the present invention are as follows:

[0017] In the present invention, inclined plates are provided for fixing the main aluminum plate body. Reserved spaces for thermal expansion and contraction are provided on the surface of the inclined plates, which facilitates the thermal expansion and contraction of the main aluminum plate body, prevents the main aluminum plate body from deforming and being damaged, and front trapezoidal blocks and rear trapezoidal blocks are provided on the surface of the inclined plates, so that the four installation parts of the main aluminum plate body all have degrees of freedom in opposite directions, and the degrees of freedom cancel each other out, so that the main aluminum plate body will not shake while having degrees of freedom for expansion. The present application also provides a decorative strip with a compensation function, so that the gap is automatically compensated during thermal expansion and contraction, and the overall appearance of the curtain wall remains unchanged.

Detailed Description of the Invention

[0029] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following detailed implementation manners are only used to further explain the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non - essential improvements and adjustments to the present application according to the above application content.

[0030] Embodiment 1

[0031] AsFigures 1-10 As shown in the figure, an aluminum single-panel curtain wall with a function of compensating for thermal expansion and contraction includes a keel steel frame 1, an aluminum plate main body 2 fixed on the keel steel frame 1 through a fixing structure 3 and having a back edge 21, and a decorative strip assembly 4 arranged between the gaps of adjacent aluminum plate main bodies 2. The cross-section of the keel steel frame 1 is in a square shape, and the angle code 31 is fixedly connected to the keel steel frame 1 through a bolt 32.

[0032] The fixing structure 3 includes an angle code 31 fixedly connected to the keel steel frame 1 and an inclined plate 33 fixedly connected to the end of the angle code 31. An inclined chute 34 is provided on the surface of the inclined plate 33. The aluminum plate main body 2 is slidably connected to the inclined chute 34 through a fixing component.

[0033] Among them, the fixing component includes a sliding rod 35 located inside the inclined chute 34, a front trapezoidal block 36 and a rear trapezoidal block 38 respectively located on both sides of the sliding rod 35 for clamping the inclined plate 33, and a threaded rod 37 connected to the front trapezoidal block 36 for fixing the aluminum plate main body 2. A reinforcing rib is provided between the back edge 21 and the aluminum plate main body 2, and a threaded groove corresponding to the threaded rod 37 is provided on the back surface of the back edge 21.

[0034] All the aluminum plate main bodies 2 in each horizontal row are supported by two mutually parallel keel steel frames 1, and the aluminum plate main body 2 is fixed on the two keel steel frames 1 through four fixing structures 3. Among them, the directions of the inclined plates 33 in the four fixing structures 3 are set according to the direction of thermal expansion and contraction of the aluminum plate main body 2 at this place. The directions of the four inclined plates 33 of each aluminum plate main body 2 are different and are radially arranged from the center of the aluminum plate main body 2 to the outside. Please refer to Figure 10 As shown in the figure, when the aluminum plate main body 2 undergoes thermal expansion, the sliding rod 35 slides along the inclined chute 34 in the expansion direction. The widths of the front trapezoidal block 36 and the rear trapezoidal block 37 are greater than that of the inclined chute 34, so that the front trapezoidal block 36 and the rear trapezoidal block 37 clamp the inclined plate 33. The purpose of setting the front trapezoidal block 36 and the rear trapezoidal block 37 is to make the aluminum plate main body 2 still not shake after leaving an expansion space. Since the inclination directions of the four inclined plates 33 are different, that is, the sliding directions of the sliding rods 35 are different. When thermal expansion and contraction do not occur, even though all four sliding rods 35 have degrees of freedom, they are restricted from each other after becoming a whole, making the aluminum plate main body 2 have no degrees of freedom. Therefore, the front trapezoidal block 36 and the rear trapezoidal block 37 play a role in fixing the aluminum plate main body 2.

[0035] In order to facilitate the assembly of the fixing structure 3, the rear trapezoidal block 38 and the end of the sliding rod 35 are detachably installed. A slot 39 corresponding to the sliding rod 35 is provided on the inclined surface of the rear trapezoidal block 38, and a fixing bolt 310 threadedly fixed to the end of the sliding rod 35 is provided through the surface of the rear trapezoidal block 38.

[0036] The decorative strip assembly 4 includes a decorative strip main body 41 and two chute blocks 42 arranged on the back surface of the decorative strip main body 41. The opening directions of the two chute blocks 42 are opposite. An L-shaped plate 43 connected in a sliding manner is arranged inside the chute block 42. A number of clamping rods 44 are arranged at the ends of the two L-shaped plates 43. A clamping groove 22 corresponding to the clamping rod 44 is arranged on the surface of the back edge 21. A spring 45 is also arranged between the two L-shaped plates 43.

[0037] The purpose of setting the decorative assembly 4 is to cover the gap between the aluminum plate main bodies 2, and a gap compensation space is reserved in the decorative strip assembly 4, so that the aluminum plate main body 2 will not affect the decorative strip assembly 4 during thermal expansion and contraction.

[0038] A slideway is formed at the gap between the two chute blocks 42. A magnetic slide bar 46 is slidably arranged in the slideway. Hinge rods 47 are hinged between the side surface of the magnetic slide bar 46 and the surfaces of the two L-shaped plates 43. Setting the magnetic slide bar 46 can release the clamping structure of the decorative strip main body 41 from the outside.

[0039] In order to increase the aesthetic degree of the butt joint of the decorative strip main body 41, an elastic right-angle pad is arranged at the butt joint between the decorative strip main body 41 and the adjacent decorative strip main body 41.

[0040] The specific implementation method is as follows: During installation, first install and fix the whole composed of the threaded rod 37, the front trapezoidal block 38 and the slide rod 35 on the aluminum plate main body 2. Screw the threaded rod 37 into the threaded hole of the back edge 21. Then butt the inclined plate 33 at the end of the angle code 31 with the slide rod 35. Subsequently, use the fixing bolt 310 to fix the rear trapezoidal block 38 and the slide rod 35. After fixing the four fixing structures 3 at the corresponding positions of the aluminum plate main body 2 respectively, finally fix the aluminum plate main body 2 on the keel steel frame 1 through the bolt 32.

[0041] When installing the decorative strip assembly 4, first bring the two L-shaped plates 43 closer to compress the spring 45, so as to facilitate the clamping rod 44 and the clamping groove 22 to enter the gap between the aluminum plate main bodies 2. Then push the decorative strip main body 41 to align the clamping rod 44 with the clamping groove 22. Under the elastic force of the spring 45, the clamping rod 44 enters the clamping groove 22. When it needs to be removed, use a strong magnet to attract the magnetic slide bar 46, and then make the magnetic slide bar 46 slide along the middle seam of the chute block 42 to drive the hinge rod 47 to pull the L-shaped plate 43 to retract.

[0042] This setting enables the L-shaped plate 43 to be compensated under the push of the spring 45 and closely adhere to the back edge 21 of the aluminum plate main body 2 when the aluminum plate main body 2 undergoes thermal expansion and contraction. Thus, the clamping rod 44 can be set very short and can always be in an interlocking state with the clamping groove 22. The shorter clamping rod 44 is also convenient for removal. When thermal expansion and contraction occur, the appearance of the curtain wall will not change.

[0043] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
