Aluminum single plate for building outer wall

Abstract

This invention relates to an aluminum panel for building exterior walls, comprising an aluminum panel body with folded edges, a keel, and an installation assembly. The installation assembly includes an upper mounting frame and a lower mounting frame. Each mounting frame includes a pair of hinged arms rotatably connected to the surface of the keel. The rotating shaft ends of the two hinged arms are provided with a meshing gear pair. One end of one hinged arm of each mounting frame protrudes beyond the mounting surface of the aluminum panel body. The protruding positions of the hinged arms of the upper and lower mounting frames are opposite, eliminating the wobbling caused by the rotational clearance of the gear pair. This installation assembly, by setting up upper and lower mounting frames and having the middle portions of the hinged arms meshed by the gear pair, allows for lateral spacing adjustment of the mounting frames, accommodating thermal expansion and contraction of the aluminum panel body in the lateral direction. Furthermore, the wobbling problem caused by the rotational clearance of the gear pair is solved by the mutual cancellation of the rotational clearance between the upper and lower mounting frames.

Description

Technical Field

[0001] This invention belongs to the field of aluminum single-panel building materials technology, specifically relating to an aluminum single-panel for building exterior walls. Background Technology

[0002] Aluminum single-panel panels are commonly used as building materials for exterior wall decoration. Due to their high plasticity, aluminum single-panel panels can be used for exterior wall decoration with straight or curved surfaces. However, aluminum single-panel panels as exterior wall decoration curtain walls have the following shortcomings: Due to the significant thermal expansion and contraction of aluminum single-panel panels, their fixed ends are generally fixed with bolts or other fixed structures. This makes aluminum single-panel panels prone to frequent thermal expansion and contraction in outdoor environments with large temperature differences, resulting in high internal stress and causing phenomena such as bulging and cracking. If a movable port fixing method is used, although there is room for thermal expansion and contraction, the non-tight fixing method is prone to causing the aluminum single-panel panels to shake and make noise. Summary of the Invention

[0003] The purpose of this invention is to provide an aluminum single-panel for building exterior walls in order to solve the above-mentioned problems.

[0004] The present invention achieves the above objectives through the following technical solutions:

[0005] An aluminum panel for building exterior walls includes an aluminum panel body with folded edges, a keel, and an installation assembly. The installation assembly includes an upper mounting frame and a lower mounting frame. Each of the upper and lower mounting frames includes two hinged arms rotatably connected to the surface of the keel. The rotating shaft ends of the two hinged arms are provided with mutually meshing gear pairs. The end of one hinged arm of each of the upper and lower mounting frames protrudes forward from the mounting surface of the aluminum panel body, and the protrusion positions of the respective hinged arms are opposite. The aluminum panel body is fixed to the ends of the four hinged arms. When the aluminum panel body is fixed, the ends of the four hinged arms are aligned on the same plane, so that both sets of gear pairs are in a meshing force state, and the meshing force directions are opposite, which is used to eliminate the rotational backlash of the gear pairs.

[0006] As a further optimization of the present invention, a fixing structure for fixing the aluminum panel body is provided at the end of the hinge arm away from the gear pair. The fixing structure includes a sleeve provided at the end of the hinge arm of the upper mounting frame, and an internally threaded slide cylinder is slidably connected inside the sleeve. An abutment is provided at the end of the hinge arm of the lower mounting frame, and a fastening rod is rotatably connected to the abutment. The fastening rod is made of the same material as the aluminum panel body. The upper end of the fastening rod passes through the internally threaded slide cylinder, and the contact surface between the fastening rod and the internally threaded slide cylinder is provided with external threads. The abutment and the internally threaded slide cylinder are used to abut and fix the upper and lower folded edges of the aluminum panel body. This solution further proposes a specific method for fixing the aluminum panel body by rotating the fastening rod to abut the internally threaded slide cylinder from inside the folded edge against the aluminum panel body.

[0007] As a further optimization of the present invention, triangular reinforcing ribs are provided between the upper and lower folded edges and the aluminum single-panel body. In order to enhance the bearing capacity of the folded edges, reinforcing ribs are provided at the abutment points of the internal threaded slide and the abutment joint.

[0008] As a further optimization of the present invention, the upper folded edge of the aluminum single panel body is provided with a notch for the fastening rod to be inserted, and the upper end of the fastening rod is provided with a rotating head for rotating the fastening rod. By providing a rotating head, the fastening rod can be rotated from the outside during installation.

[0009] As a further optimization of the present invention, the upper folded edge of the aluminum single panel body is provided with a U-shaped upper bracket that connects with the internal threaded slide cylinder, and the lower folded edge is provided with a circular lower bracket that corresponds to the abutment. The lower bracket and the upper bracket are provided with chamfers inside. By setting the upper bracket and the lower bracket, the internal threaded slide cylinder and the abutment have a docking base, thereby improving the fixing effect.

[0010] As a further optimization of the present invention, the upper and lower ends of the internally threaded slide cylinder are provided with limiting edges for limiting the vertical sliding range of the internally threaded slide cylinder. The inner wall of the sleeve is provided with vertical grooves, the inner wall of the upper retaining seat is provided with limiting grooves, and the upper end surface of the internally threaded slide cylinder is provided with a limiting strip. When the internally threaded slide cylinder moves upward into the upper retaining seat, the limiting strip leaves the sleeve, thereby allowing the internally threaded slide cylinder and the sleeve to have rotational freedom. In this solution, to facilitate the upward movement of the internally threaded slide cylinder, a limiting strip is provided on the internally threaded slide cylinder... A limiting strip is provided on the outer surface of the end. The limiting strip initially aligns with the vertical grooves on the inner wall of the sleeve, thereby limiting the rotation of the internal threaded slide cylinder when the fastening rod rotates, preventing the internal threaded slide cylinder from rotating and allowing it to move upward. After the internal threaded slide cylinder moves upward, it enters the upper retainer, and the upper retainer restricts the rotation of the internal threaded slide cylinder. At this time, there is a rotational degree of freedom between the internal threaded slide cylinder and the sleeve. This rotational degree of freedom allows the connection between the aluminum panel body and the hinge arm to be equivalent to a hinge. Thus, when the aluminum panel body expands and contracts with heat, the hinge arm can retract to adapt.

[0011] As a further optimization of the present invention, a sealing strip is provided between the gaps of the aluminum single panel body to improve the aesthetics.

[0012] The beneficial effects of the present invention are as follows: By setting up an upper mounting bracket and a lower mounting bracket, and making the middle part of the hinge arm mesh with a gear pair, the mounting brackets can be adjusted in the lateral direction, so that the aluminum single panel body has space for thermal expansion and contraction in the lateral direction. Furthermore, the rotation gaps of the upper and lower mounting brackets cancel each other out, thus solving the shaking problem caused by the rotation gap of the gear pair.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1

[0023] like Figure 1-8As shown, an aluminum single-panel for building exterior walls includes an aluminum single-panel body 1 with folded edges 101, a keel 2, and an installation assembly 3. The installation assembly 3 includes an upper mounting frame 3a and a lower mounting frame 3b. Each of the upper mounting frame 3a and the lower mounting frame 3b includes two hinge arms 301 rotatably connected to the surface of the keel 2. The rotating shaft ends of the two hinge arms 301 are provided with mutually meshing gear pairs 302. The end of one hinge arm 301 of each of the upper mounting frame 3a and the lower mounting frame 3b protrudes forward from the mounting surface of the aluminum single-panel body 1, and the protrusion positions of the respective hinge arms 301 are opposite. The aluminum single-panel body 1 is fixed to the ends of the four hinge arms 301. When the aluminum single-panel body 1 is fixed, the ends of the four hinge arms 301 are located on the same plane, so that the two sets of gear pairs 302 are in a meshing force state, and the meshing force directions are opposite, which is used to eliminate the rotational backlash of the gear pairs 302.

[0024] In this design, by setting up an upper mounting bracket 3a and a lower mounting bracket 3b, and by having the middle part of the hinge arm 301 mesh with a gear pair 302, the mounting brackets can be adjusted laterally to allow for thermal expansion and contraction of the aluminum panel body 1. The gear pair 302 ensures that the two hinge arms 301 can only open or close simultaneously. After the ends of the hinge arms 301 are fixed to the aluminum panel body 1, they provide a fixing function. When lateral thermal expansion and contraction occurs, the adjustment of the hinge arms 301's opening and closing distance can accommodate the lateral thermal expansion and contraction. However, there is a rotational clearance between the gear pairs 302. This clearance means that although the two hinge arms 301 open and close synchronously, there is still a gap in the "synchronization." This gap can easily cause the aluminum panel body 1 to swing left and right in the horizontal direction. To compensate for the rotational clearance, each of the upper and lower mounting brackets has a hinge arm 301 protruding forward, such as... Figure 4 As shown, when the aluminum panel body 1 is installed, the gear pair 302 is in a tightly meshed state. The tightly meshing directions of the upper and lower mounting brackets are exactly opposite. Therefore, no matter which way the aluminum panel body 1 swings in the horizontal direction, there will be a tightly meshed gear pair 302 to block in that swinging direction, thereby eliminating the shaking.

[0025] The end of the hinge arm 301 away from the gear pair 302 is provided with a fixing structure for fixing the aluminum panel body 1. The fixing structure includes a sleeve 303 at the end of the hinge arm 301 of the upper mounting bracket 3a, and an internally threaded slide cylinder 304 is slidably connected inside the sleeve 303. The end of the hinge arm 301 of the lower mounting bracket 3b is provided with an abutment 403, and a fastening rod 4 is rotatably connected to the abutment 403. The fastening rod 4 is made of the same material as the aluminum panel body 1. The upper end of the fastening rod 4 passes through the internally threaded slide cylinder 304, and the contact surface between the fastening rod 4 and the internally threaded slide cylinder 304 is provided with an external thread 402. The abutment 403 and the internally threaded slide cylinder 304 are used for clamping. The upper and lower folded edges 101 of the fixed aluminum panel body 1 are further proposed in this solution. The specific method of fixing the aluminum panel body 1 is proposed by rotating the fastening rod 4 to press the internal threaded sliding cylinder 304 against the aluminum panel body 1 from the inside of the folded edge 101. This fixing structure allows the aluminum panel body 1 to have vertical freedom. When thermal expansion and contraction occur, since the fastening rod 4 and the aluminum panel body 1 are made of the same material, when the aluminum panel body 1 undergoes vertical thermal expansion and contraction, the fastening rod 4 also undergoes thermal expansion and contraction. The fastening rod 4 drives the internal threaded cylinder 304 to slide along the sleeve 303, which has vertical freedom, so that the aluminum panel body 1 has vertical thermal expansion and contraction space.

[0026] Triangular reinforcing ribs 102 are provided between the upper and lower folded edges 101 and the aluminum single panel body 1. In order to enhance the bearing capacity of the folded edges 101, reinforcing ribs 102 are provided at the abutment of the internal threaded slide cylinder 304 and the abutment joint 403.

[0027] The upper folded edge 101 of the aluminum single panel body 1 is provided with a notch 105 for the fastening rod 4 to be inserted, and the upper end of the fastening rod 4 is provided with a rotating head 401 for rotating the fastening rod 4. By providing the rotating head 401, the fastening rod 4 can be easily rotated from the outside during installation.

[0028] The upper folded edge 101 of the aluminum single panel body 1 is provided with a U-shaped upper bracket 103 that mates with the internal threaded slide cylinder 304, and the lower folded edge 101 is provided with a circular lower bracket 104 that corresponds to the abutment 403. The lower bracket 104 and the upper bracket 103 are chamfered inside. By setting the upper bracket 103 and the lower bracket 104, the internal threaded slide cylinder 304 and the abutment have a mating base, which improves the fixing effect.

[0029] The upper and lower ends of the internal threaded slide cylinder 304 are provided with limiting edges 305 for limiting the vertical sliding range of the internal threaded slide cylinder 304. The inner wall of the sleeve 303 is provided with vertical grooves, the inner wall of the upper retainer 103 is provided with limiting grooves 106, and the upper side surface of the internal threaded slide cylinder 304 is provided with a limiting strip 306. When the internal threaded slide cylinder 304 moves upward into the upper retainer 103, the limiting strip 306 leaves the sleeve 303, so that the internal threaded slide cylinder 304 and the sleeve 303 have rotational freedom.

[0030] In this design, to facilitate the upward movement of the internally threaded slide cylinder 304, a limiting strip 306 is provided on the outer surface of the upper end of the internally threaded slide cylinder 304. The limiting strip 306 initially aligns with the vertical grooves on the inner wall of the sleeve 303, thereby limiting the internally threaded slide cylinder 304 when the fastening rod 4 rotates, preventing the internally threaded slide cylinder 304 from rotating, so that the internally threaded slide cylinder 304 can move upward. After the internally threaded slide cylinder 304 moves upward and enters the upper retainer 103, the upper retainer 103 restricts the rotation of the internally threaded slide cylinder 304. At this time, there is a rotational degree of freedom between the internally threaded slide cylinder 304 and the sleeve 303. This rotational degree of freedom allows the connection between the aluminum panel body 1 and the hinge arm 301 to be equivalent to a hinge. Thus, when the aluminum panel body 1 expands and contracts thermally, the hinge arm 301 can be extended and retracted to adapt to the change in lateral spacing caused by thermal expansion and contraction.

[0031] Sealing strips 5 are provided between the gaps of the aluminum single-panel body 1 to improve aesthetics. The above embodiments only illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
