Description

Technical Field

[0001] This invention relates to a leveling device, specifically to a leveling device and method for aluminum single-panel curtain walls. Background Technology

[0002] The roof of a certain hospital project uses a large-area cantilevered aluminum single-panel curtain wall. The aluminum single-panel curtain wall not only serves as decoration for the building itself, but also provides protection for the building's exterior.

[0003] During the installation of aluminum panel curtain walls, it is essential to ensure the flatness of individual panels to guarantee the overall flatness of the installed curtain wall. However, during installation, unintentional stepping or placing heavy objects on the panels can cause dents and deformations. After rain, water can accumulate in these dents, severely impacting the structure. The traditional method to address this issue is to use suction cups to hold the panels in place before installation and then manually pull and adjust them. This traditional method has limited effectiveness and cannot level severely dented panels. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a curtain wall panel leveling device and method, which aims to level and correct recessed curtain wall panels during or after construction.

[0005] The technical solution adopted in this invention is: a curtain wall panel leveling device, comprising a fixing clamp, an adjusting mechanism and a tightening mechanism;

[0006] The fixing clamps are in two sets, respectively located at both ends of the clamping mechanism, and the fixing clamps are connected to the keel on the back of the curtain wall panel;

[0007] One end of the adjustment mechanism is connected to the fixed clamp, and the other end of the adjustment mechanism is connected to the tightening mechanism, and the length of the connection section between the adjustment mechanism and the tightening mechanism is adjustable;

[0008] The middle part of the clamping mechanism can arch outward to contact the curtain wall panel.

[0009] According to the above scheme, each side of the tightening mechanism is provided with an adjusting bolt, and the adjusting bolt is threadedly connected to the end of the adjusting mechanism.

[0010] According to the above scheme, the clamping mechanism is a spring steel plate or a spring steel bar.

[0011] According to the above scheme, the fixing fixture includes a base plate, two vertical clamping plates and a spring; the upper surface of the base plate is provided with a sliding groove, and a vertical clamping plate is provided at each end of the sliding groove. The bottom of the clamping plate is connected to a slider that is adapted to the sliding groove; the two sliders are connected by a spring, and the spring is located in the sliding groove; the keel on the back of the curtain wall panel is located between the two clamping plates.

[0012] According to the above scheme, the slide is a T-shaped groove and the slider is a T-shaped block.

[0013] According to the above scheme, a limiting plate is also provided on the bottom plate on the outer side of the clamping plate.

[0014] According to the above scheme, the fixing fixture includes a base plate, two clamping plates fixed to the base plate, and locking bolts; the keel on the back of the curtain wall is located between the two clamping plates; the clamping plates are provided with locking bolt holes that are compatible with the locking bolts, and the inner end of the locking bolt passes through the locking bolt holes of the clamping plates and is pressed against the side of the keel.

[0015] According to the above scheme, the clamping plate of the fixing fixture is provided with a vertical slot, which is adapted to the end of the adjustment mechanism.

[0016] According to the above scheme, the adjusting mechanism includes a clamping connector, a screw, a limiting nut, and a sleeve; the clamping connector is threaded to one end of the screw, the clamping connector is located in a clamping groove, the screw extends out from the clamping groove and is connected to the limiting nut; one end of the sleeve is threaded to the screw, and the other end of the sleeve is threaded to the adjusting bolt of the tightening mechanism.

[0017] The present invention also provides a method for leveling curtain wall panels, the method comprising the following steps:

[0018] Step 1: Provide the components of the curtain wall panel leveling device as described above;

[0019] Step 2: Initially install the fixing clamps of the curtain wall leveling device on the keel on both sides of the recessed area of ​​the curtain wall panel;

[0020] Step 3: Connect the adjustment mechanism to the adjustment bolts at both ends of the spring steel plate, then assemble the adjustment mechanism onto the fixing clamp, and adjust the installation height of the adjustment mechanism and the position of the fixing clamp so that the middle of the spring steel plate corresponds to the position of the recessed part of the curtain wall panel.

[0021] Step 4: Manually rotate the sleeve to reduce the length of the connection between the spring steel plate and the sleeve. The spring steel plate is squeezed and arches outward in the middle, squeezing the concave curtain wall panel until the curtain wall panel is straightened and flat.

[0022] The beneficial effects of this invention are as follows: 1. All components of the curtain wall panel leveling device described in this invention, such as the fixing clamps, adjusting mechanism, and tightening mechanism, are detachably connected, unaffected by construction. It can correct and level recessed curtain wall panels during and after construction. The structure is simple, the design is reasonable, and the operation is convenient, effectively solving the problem of recesses caused by trampling during construction. 2. In this invention, the tightening mechanism is located on the back of the curtain wall panel. Leveling is achieved by applying force to the curtain wall panel through deformation of the tightening mechanism, resulting in good leveling effect. Furthermore, the tightening mechanism applies force to the curtain wall panel slowly, and the applied force decreases as the aluminum panel is corrected, avoiding over-correction of the curtain wall panel, making it flexible and reliable. 3. In this invention, when the length of the connection section between the spring steel plate and the adjusting mechanism decreases and the spring steel plate is compressed, it also squeezes the fixing clamps on the keel, making the fixing clamps more firmly installed on the keel under lateral force.

[0030] To better understand the present invention, it will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Multiple keels 5 are installed at intervals on the back of the curtain wall panel 4, and the panel is fixed by the keels 5. In this embodiment, the curtain wall panel 4 is a single-layer aluminum curtain wall panel 4.

[0032] like Figures 1-3 The curtain wall panel leveling device shown is specifically an aluminum curtain wall panel leveling device, including a fixing clamp 1, an adjusting mechanism 2 and a tightening mechanism 3;

[0033] The fixing clamp 1 has two sets, which are respectively located at both ends of the clamping mechanism 3. The fixing clamp 1 is connected to the keel 5 on the back of the curtain wall panel 4.

[0034] One end of the adjusting mechanism 2 is connected to the fixed clamp 1, and the other end of the adjusting mechanism 2 is connected to the tightening mechanism 3. The length of the connection section between the adjusting mechanism 2 and the tightening mechanism 3 is adjustable.

[0035] The middle part of the clamping mechanism 3 can arch outward and contact the curtain wall panel 4.

[0036] In this invention, when the length of the connecting section between the adjusting mechanism 2 and the tightening mechanism 3 becomes shorter, the tightening mechanism 3 is deformed by force, and the middle part of the tightening mechanism 3 arches outward, squeezing the recessed part of the curtain wall panel 4 and correcting the curtain wall panel 4.

[0037] Preferably, each side of the tightening mechanism 3 is provided with an adjusting bolt 3.1; the adjusting bolt 3.1 is threadedly connected to the end of the adjusting mechanism 2. When installing the tightening mechanism 3, the degree of compression of the spring steel plate or spring steel strip during installation is determined. The exposed thread length of the adjusting bolt 3.1 is determined using a normal curtain wall panel 4. The exposed thread length of the adjusting bolt 3.1 and the height of both ends of the spring steel plate or spring steel strip at this time are recorded. Then, the spring steel plate or spring steel strip is installed under the deformed curtain wall panel 4 so that the height of both ends of the spring steel plate or spring steel strip is consistent with the recorded height, and the exposed thread length of the adjusting bolt is also consistent with the recorded length.

[0038] In this invention, the tightening mechanism 3 is a spring steel plate or a spring steel bar, and adjusting bolts 3.1 are provided on both sides of the spring steel plate or spring steel bar.

[0039] Preferably, such as Figure 4 and Figure 5 As shown, the fixing clamp 1 includes a base plate 1.1, two vertical clamping plates 1.2, and a spring 1.7; the upper surface of the base plate 1.1 is provided with a sliding groove 1.5, and a vertical clamping plate 1.2 is provided at each end of the sliding groove 1.5. The bottom of the clamping plate 1.2 is connected to a slider 1.6 that is adapted to the sliding groove 1.5; the two sliders 1.6 are connected by a spring 1.7, which is located inside the sliding groove 1.5; the keel 5 on the back of the curtain wall panel 4 is located between the two clamping plates 1.2. Under the action of the spring 1.7, the inner sides of the two clamping plates 1.2 are tightly attached to the keel 5, clamping the keel 5.

[0040] Preferably, the groove 1.5 is a T-shaped groove, and correspondingly, the slider 1.6 is a T-shaped block.

[0041] In this invention, there are at least two sets of sliding grooves 1.5, and the length direction of the sliding grooves 1.5 is consistent with the axial direction of the adjusting bolts 3.1 of the tightening mechanism 3.

[0042] Preferably, a limiting plate is also provided on the bottom plate 1.1 on the outer side of the clamping plate 1.2 to prevent the clamping plate 1.2 from sliding out of the bottom plate 1.1.

[0043] In this invention, the two clamping plates 1.2 are clamped together by the spring force to fix the keel 5. If the keel 5 is an angle steel, appropriately sized pads can be added to both sides of the keel 5.

[0044] In this invention, when the width of the keel 5 is too small and the fixing clamp 1 described above is not stable, the following method can be used: Figure 6 The fixing clamp 1 shown is preferably a base plate 1.1, two clamping plates 1.2 fixed opposite to each other on the base plate 1.1, and a locking bolt 1.8; the keel 5 on the back of the curtain wall is located between the two clamping plates 1.2; the clamping plates 1.2 are provided with locking bolt holes 1.9 that are adapted to the locking bolts 1.8, and the inner end of the locking bolt 1.8 passes through the locking bolt hole 1.9 of the clamping plate 1.2 and is pressed against the side of the keel 5.

[0045] In this invention, in order to adjust the distance between the clamping mechanism 3 and the curtain wall panel 4, a slot 1.3 structure can be designed to adjust the vertical connection position between the adjusting mechanism 2 and the fixing clamp 1. Preferably, the clamping plate 1.2 of the fixing clamp 1 is provided with a vertical slot 1.3, and the slot 1.3 is adapted to the end of the adjusting mechanism 2.

[0046] Preferably, such as Figure 2 and Figure 3 As shown, the adjusting mechanism 2 includes a clamping connector 2.1, a screw 2.2, a limiting nut 2.3, and a sleeve 2.4; the clamping connector 2.1 is threadedly connected to one end of the screw 2.2, the clamping connector 2.1 is located in the clamping groove 1.3, and the screw 2.2 extends out from the clamping groove 1.3 and is connected to the limiting nut 2.3; one end of the sleeve 2.4 is threadedly connected to the screw 2.2, and the other end of the sleeve 2.4 is threadedly connected to the adjusting bolt 3.1 of the tightening mechanism 3.

[0047] In this invention, the lower end of the slot 1.3 has a large diameter, forming a round hole adapted to fit the connector 2.1 for insertion. The outer opening of the slot 1.3 has a diameter larger than the outer diameter of the screw 2.2 but smaller than the outer diameter of the connector 2.1, facilitating the extension of the screw 2.2. The limiting nut 2.3 is located on the outside of the slot 1.3. Once the position of the connector 2.1 within the slot 1.3 is determined, tightening the limiting nut 2.3 presses it against the side of the clamping plate 1.2, thus limiting the adjustment mechanism 2 on the fixing fixture 1. In this invention, the position of the connector 2.1 within the slot 1.3 is adjustable, which can assist in controlling the distance between the curtain wall panel 4 and the spring steel plate or spring steel strip, thereby expanding the deformation range of the curtain wall panel 4.

[0048] In this invention, to prevent the snap-fit ​​connector 2.1 from getting stuck in the slot 1.3 and unable to move, a slot 1.4 communicating with the slot 1.3 can be provided on the top of the clamping plate 1.2. When the snap-fit ​​connector 2.1 is stuck, a push rod can be inserted into the slot 1.4 to tighten the snap-fit ​​connector 2.1, causing the snap-fit ​​head to move. The sleeve 2.4 is threadedly connected to the screw 2.2 and the tightening mechanism 3. When the sleeve 2.4 is rotated, the screw 2.2 and the tightening mechanism 3 move and rotate in opposite directions. If the screw 2.2 and the tightening mechanism 3 move in opposite directions, the connection section between the adjusting bolt 3.1 of the tightening mechanism 3 and the sleeve 2.4 becomes shorter, and the two ends of the tightening mechanism 3 are deformed by pressure, with the middle arching outward, squeezing the curtain wall panel 4. If the screw 2.2 and the tightening mechanism 3 move in opposite directions, the connection section between the adjusting bolt of the tightening mechanism 3 and the sleeve 2.4 becomes longer, and the deformation of the tightening mechanism 3 becomes smaller, at which point the force on the curtain wall panel 4 becomes smaller.

[0049] In this embodiment, the clamping mechanism 3 is a spring steel plate.

[0050] The present invention also provides a method for leveling curtain wall panels, the method being:

[0051] Step 1: Provide the components of the curtain wall panel leveling device as described above;

[0052] Step 2: Initially install the fixing clamp 1 of the curtain wall leveling device on the keel 5 on both sides of the recess of the curtain wall panel 4;

[0053] Step 3: Connect the adjustment mechanism 2 to the adjustment bolts 3.1 at both ends of the spring steel plate, and then assemble the adjustment mechanism 2 onto the fixing clamp 1. Adjust the installation height of the adjustment mechanism 2 and the position of the fixing clamp 1 so that the middle part of the spring steel plate corresponds to the position of the recessed part of the curtain wall panel 4.

[0054] Step 4: Manually rotate sleeve 2.4 to reduce the length of the connection between the spring steel plate and sleeve 2.4. The spring steel plate is squeezed and arches outward in the middle, squeezing the concave curtain wall panel 4 until the curtain wall panel 4 is straightened and flattened.

[0055] The leveling device for the curtain wall panel 4 described in this invention can be used during the installation of the curtain wall panel 4 to prevent the curtain wall panel 4 from sinking during the installation process. It can also be used to correct any sinking curtain wall panel 4 after the curtain wall panel 4 has been installed, so that the curtain wall panel 4 is flat.

[0056] In this invention, a spring steel plate or spring steel strip is designed so that the deformation of the spring steel plate or spring steel strip is reduced during the straightening process of the aluminum curtain wall panel 4; after the aluminum curtain wall panel 4 is straightened, the elasticity of the spring steel plate or spring steel strip approaches zero, and the aluminum curtain wall panel will not change from concave to convex.

[0058] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
