Description

Technical Field

[0001] This invention relates to the field of building curtain wall engineering technology, specifically to a self-locking cable-stayed curtain wall ball hinge clamp and its installation method. Background Technology

[0002] Cable-stayed facades are a type of modern building envelope composed of steel cable trusses and glass panels. They offer advantages such as excellent transparency, aesthetic appeal, and lightweight construction, and are widely used in large public buildings. In cable-stayed facade structures, the clamps, as key components connecting the glass panels to the flexible cables, directly impact the construction efficiency, load-bearing capacity, and subsequent maintenance costs of the facade system through their structural form and installation method.

[0003] Cable-stayed curtain wall fixtures consist of a base and a cover plate. In existing technologies, the cover plate is often an integral structure. During installation, the base is first fixed to the cable, then the corners of multiple curtain wall glass panels to be installed are inserted, and finally the cover plate is locked with screws.

[0004] The aforementioned traditional cable-stayed curtain wall clamps have the following problems during installation: 1. High risk: The glass curtain wall to be installed needs to be completely placed in before being fixed with cover plates, which poses certain safety hazards.

[0005] 2. Low installation efficiency: During the construction process, each clamp needs to tighten multiple screws, which is a long operation process and consumes a lot of manpower and time.

[0006] 3. High dependence on tools: Specialized tools such as screwdrivers or wrenches must be used, which not only increases the complexity of operation when working at heights, but also poses a risk of tools falling.

[0007] 4. Inconvenient maintenance: When replacing glass, it is necessary to loosen the screws one by one and remove the cover plate, which increases the risk of spontaneous breakage or loosening of adjacent glass due to changes in the stress state. Summary of the Invention

[0008] To address the aforementioned shortcomings of existing technologies, a self-locking cable-stayed curtain wall ball hinge clamp and its installation method are provided, which eliminates the need for tools and improves installation efficiency.

[0009] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: A self-locking cable-stayed curtain wall ball hinge clamp includes a clamp body for fixing to the cable and a clamping device for fixing the curtain wall glass. The clamping device includes a clamp bottom cover, which is fixed to the clamp body. The clamp bottom cover is provided with multiple partition units, which are arranged circumferentially around the center of the clamp bottom cover. Each partition unit is hinged with a cover plate at its top. Each partition unit is provided with a locking unit. When the cover plate is closed, it cooperates with the locking unit in the adjacent partition unit to clamp and fix the curtain wall glass. The clamp bottom cover and the cover plate are respectively equipped with corresponding ball joint assemblies, which are used to fix the glass curtain wall.

[0010] According to the above technical solution, the partition unit includes a lock lug plate, a lock sub-plate, and a cover plate connecting plate. The lock lug plate and the cover plate connecting plate are fixedly installed on the bottom cover of the clamp. The lock sub-plate is located between the lock lug plate and the cover plate connecting plate and is fixedly connected to the lock lug plate and the cover plate connecting plate. The top of the cover plate is hinged to the cover plate connecting plate, and the locking unit is located inside the lock lug plate and the lock sub-plate.

[0011] According to the above technical solution, the locking unit includes a vertically arranged locking pin hole and an unlocking pin hole, and a connecting pin hole that connects the locking pin hole and the unlocking pin hole laterally; a first elastic element is provided in the locking pin hole, an unlocking pin is movably installed in the unlocking pin hole, and a connecting pin and a second elastic element are movably installed in the connecting pin hole; the cover plate has a locking hole and an unlocking hole. When locking the cover plate, the locking pin is inserted into the locking hole and the locking pin hole, and the locking pin pushes the connecting pin to compress the second elastic element through the wedge surface that cooperates with the connecting pin. After the locking pin is in place, the connecting pin is inserted into the fixing hole on the locking pin under the action of the rebound force of the second elastic element. When unlocking the cover plate, the unlocking pin is pressed with a thin rod, and the unlocking pin pushes the connecting pin out of the fixing hole through the wedge surface that cooperates with the connecting pin. The locking pin pops out under the action of the first elastic element.

[0012] According to the above technical solution, the locking pin is provided with a vertical anti-rotation groove, which is slidably connected with the anti-rotation strip in the locking pin hole to prevent the locking pin from rotating in the locking pin hole.

[0013] According to the above technical solution, the ball joint assembly includes a ball joint support and a ball joint bracket. The concave surface of the ball joint support and the convex surface of the ball joint bracket cooperate with each other, and the ball joint support and the ball joint bracket are fixedly connected by fasteners.

[0014] According to the above technical solution, the ball joint support is made of elastic rubber material.

[0015] According to the above technical solution, the fixture body includes multiple installation units stacked sequentially from top to bottom, and each installation unit has a reserved hole for threading and fixing the cable.

[0016] According to the above technical solution, the multiple mounting units are provided with mutually cooperating bolt holes and are fixedly connected by screws.

[0017] According to the above technical solution, the surface of the uppermost mounting unit is provided with a mounting frame, and a central column is provided on the mounting frame. The bottom cover of the clamp is sleeved on the central column and fixedly connected to the mounting frame.

[0018] This invention also proposes an installation method for a self-locking cable-stayed curtain wall ball hinge clamp, comprising the following steps: S1. Install the clamp body on the cable, fix the clamp bottom cover on the clamp body, and then install the partition unit; S2. Place the curtain wall glass between the corresponding partition units, close the corresponding cover plate and lock it through the locking unit, and clamp and fix the curtain wall glass with the ball hinge assembly. S3. Repeat step S2 until all the glass curtain walls are installed.

[0019] The present invention has the following beneficial effects: 1. The present invention has multiple dividing units on the bottom cover of the clamp, and a cover plate is hinged to the top of each dividing unit, so that each cover plate can independently fix a corner of the curtain wall glass, thereby realizing the installation of curtain wall glass piece by piece, improving construction flexibility and installation efficiency.

[0020] 2. This invention uses a pin-locking method to fix the cover plate. During construction, only the locking pin needs to be inserted, and the cover plate can be fixed after automatic locking. When installing curtain wall glass at high altitudes, there is no need to carry screws, wrenches and other tools, which reduces tool dependence and also reduces the risk of tools falling from high altitudes.

[0021] 3. This invention features a built-in unlocking pin, which requires a thin rod to press to unlock the cover, thus avoiding the risk of accidental locking and improving security.

[0022] 4. When it is necessary to replace the curtain wall glass, the present invention only requires unlocking the corresponding cover plate, while the other adjacent glass remains fixed, which improves the convenience and safety of glass replacement. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Reference Figures 1-9As shown, the present invention provides a self-locking cable-stayed curtain wall ball hinge clamp and its installation method.

[0027] Example 1 The invention includes a clamp body 1 for fixing to a cable and a clamping device for fixing curtain wall glass. The clamping device includes a clamp bottom cover 2, which is fixed to the clamp body 1. The clamp bottom cover 2 has multiple partition units 3 arranged circumferentially around the center of the clamp bottom cover. Each partition unit 3 has a cover plate 4 hinged to its top. A locking unit 5 is provided within each partition unit 3. When the cover plate 4 is closed, it cooperates with the locking unit 5 in the adjacent partition unit 3 to clamp and fix the curtain wall glass. Corresponding ball joint assemblies 6 are installed on the clamp bottom cover 2 and the cover plate 4, respectively, for fixing the glass curtain wall. This invention provides multiple partition units 3 on the clamp bottom cover 2, with a cover plate 4 hinged to the top of each partition unit 3, allowing each cover plate 4 to independently fix a corner of the curtain wall glass, thus enabling the installation of each curtain wall glass piece by piece. Furthermore, the cover plate 4 is fixed by a pin-locking method, eliminating the need for tools and improving construction flexibility and installation efficiency.

[0028] In this embodiment, the partition unit 3 includes a lock lug plate 301, a lock sub-plate 302, and a cover plate connecting plate 303. The lock lug plate 301 and the cover plate connecting plate 303 have mounting plates at their bottoms, which are fixed to the fixture bottom cover 2 by screws or bolts. The lock sub-plate 302 is located between the lock lug plate 301 and the cover plate connecting plate 303. Each of the four corners of the lock sub-plate 302, lock lug plate 301, and cover plate connecting plate 303 has mating screw holes for fixing. The top of the cover plate connecting plate 303 has a pivot hole 510. The cover plate 4 is hinged to the pivot hole 510 via a steering interface 403, allowing the cover plate 4 to rotate relative to the cover plate connecting plate 303.

[0029] In this embodiment, the locking unit 5 is disposed within the lock lug plate 301 and the lock sub-plate 302, and includes a locking pin hole 501, an unlocking pin hole 502, and a connecting pin hole 503 formed in the contact surface of the lock lug plate 301 and the lock sub-plate 302. The locking pin hole 501 and the unlocking pin hole 502 are vertically arranged, and the connecting pin hole 503 is horizontally connected to the locking pin hole 501 and the unlocking pin hole 502. A first spring 504 is provided at the bottom of the locking pin hole 501, an unlocking pin 506 is movably installed in the unlocking pin hole 502, and a connecting pin 508 is movably installed in the connecting pin hole 503. A second spring 505 is provided at the right end of the connecting pin 508. The cover plate 4 has a locking hole 401 and an unlocking hole 402.

[0030] In this embodiment, after the cover plate 4 is flipped closed, the locking pin 507 is inserted into the locking pin hole 501 through the locking hole 401. A wedge-shaped surface is provided between the locking pin 507 and the connecting pin 508. When the locking pin 507 is inserted downwards, the wedge-shaped surface pushes the connecting pin 508 to the right, compressing the second spring 505. After the locking pin 507 is fully inserted, the connecting pin 508, under the action of the rebound force of the second spring 505, inserts into the fixing hole 511 on the side wall of the locking pin 507 and engages, thus locking the cover plate 4. When it is necessary to unlock the cover plate 4, a thin rod is used to press down on the unlocking pin 506. A wedge-shaped surface is also provided between the unlocking pin 506 and the connecting pin 508. When the unlocking pin 506 is inserted downwards, the wedge-shaped surface pushes the connecting pin 508 to the right, causing the front end of the connecting pin 508 to exit the fixing hole 511. The locking pin 507 pops out under the action of the first spring 504, thus unlocking the cover plate 4.

[0031] In this embodiment, a vertical anti-rotation groove 509 is provided on the locking pin 507, and an anti-rotation strip is provided on the inner wall of the locking pin hole 501 to cooperate with it, so that the locking pin 507 can only move up and down in the locking pin hole 501 and cannot rotate, thereby avoiding misalignment between the wedge surface at the bottom of the locking pin 507 and the wedge surface on the connecting pin 508.

[0032] In this embodiment, the wedge surface between the locking pin 507 and the connecting pin 508, and between the unlocking pin 506 and the connecting pin 508, is preferably 45°.

[0033] In this embodiment, the unlocking pin 506 is completely built into the lock ear plate 301 and the lock sub-plate 302, which prevents accidental contact from unlocking the cover plate 4 and improves security.

[0034] In this embodiment, a pad is provided between the locking pin 507 and the first spring 504, and between the connecting pin 508 and the second spring 505, so that the first spring 504 and the second spring 505 can push the locking pin 507 and the connecting pin 508.

[0035] In this embodiment, the cover plate 4 is provided with a locking hole 401 and an unlocking hole 402. The locking hole 401 is aligned with the locking pin hole 501, and the unlocking hole 402 is aligned with the unlocking pin hole 502. The upper diameter of the locking hole 401 is larger to accommodate the pin head of the locking pin 507, maintaining the overall aesthetic appearance.

[0036] In this embodiment, the ball joint assembly 6 includes a ball joint support 601 and a ball joint bracket 602. The bottom of the ball joint support 601 is fixed to the cover plate 4 and the clamp bottom cover 2 by threads. The concave surface of the ball joint support 601 and the convex surface of the ball joint bracket 602 cooperate with each other. The ball joint support 601 and the ball joint bracket 602 are fixed together by fastening bolts 603.

[0037] In this embodiment, the ball joint support 601 has a protruding post at the connection with the ball joint bracket 602, and the bottom of the ball joint bracket 602 has an opening with a diameter slightly larger than the protruding post. The ball joint bracket 602 is made of elastic rubber material, so that after the fastening bolt 603 is fixed, the ball joint bracket 602 can be finely adjusted within the ball joint support 601 to achieve adjustable angle clamping and fixing of the curtain wall glass.

[0038] In this embodiment, the ball hinge support 601 has a simple structure, is easy to process to different heights, and can flexibly adapt to curtain wall glass of different thicknesses.

[0039] Example 2 The principle and technical solution of Embodiment 2 are basically the same as those of Embodiment 1, except that a specific structural form of the fixture body 1 and the fixture bottom cover 2 is given.
