Description

Technical Field

[0001] The invention relates to the technical field of curtain walls, and in particular to a large-span double-column unit curtain wall system. Background Art

[0002] In the field of modern architecture, large-span double-column unit curtain wall systems are widely used in the exterior decoration of large commercial complexes, high-rise office buildings, high-end hotels and other buildings due to their unique aesthetic effects and excellent structural performance. This type of curtain wall system usually adopts a double-column design to enhance the stability and bearing capacity of the structure. At the same time, adjacent columns are reinforced with transverse keels to form a stable support system. The vertical keels are tightly fixed to the wall through precisely designed connectors and anchor bolts to ensure that the curtain wall system can withstand the influence of external factors such as wind pressure and temperature changes. China has authorized a utility model patent (Announcement No.: CN218149114U) to disclose a double-column glass curtain wall structure and a glass curtain wall, including a curtain wall, multiple groups of double columns and transverse keels. The fixed ends of the transverse keels and double columns are provided with silicone pads to effectively prevent certain effects on the stability of the frame. However, the device still has certain defects when in use and needs to be improved;

[0003] In the connection method of the prior art, when the connecting parts are fastened to the anchor bolts by bolts, there is often a lack of an effective limiting mechanism for the nut. This leads to the possibility that during long-term use, the nut may rotate slightly under the influence of various factors such as wind, temperature changes, and building vibrations, thereby causing the connection to loosen. Once the connection is loose, it will not only affect the overall stability of the curtain wall system, but may also cause safety hazards such as glass falling off and water leakage, posing a threat to the safe use of the building. Therefore, a large-span double-column unit curtain wall system is proposed to overcome the above-mentioned defects. Summary of the invention

[0004] The object of the present invention is to provide a large-span double-column unit curtain wall system, which limits the position of nuts by C-shaped blocks and limiting rods, thereby realizing the function of preventing the nuts from loosening.

[0005] The present invention is achieved through the following technical solutions:

[0006] The invention discloses a large-span double-column unit curtain wall system, comprising a curtain wall body, double columns and transverse keels.

[0007] The double columns have a vertical keel, a connecting piece is installed on the vertical keel, a spacer is installed on the connecting piece, a connecting groove is opened on the connecting piece, there are two connecting grooves, L-shaped blocks are installed in the two connecting grooves, C-shaped blocks are installed on the two L-shaped blocks, a first limiting groove is opened on the L-shaped block, a limiting rod is connected in the first limiting groove, a blocking piece is installed on the limiting rod, and a spring is connected between the blocking piece and the spacer.

[0008] There are two convex grooves on the vertical keel. Limiting pieces are slidably fitted in the two convex grooves. Limiting blocks are installed on the two limiting pieces. Reserved grooves that match the horizontal keel are opened in the two limiting blocks. Second limiting grooves are opened in the two limiting blocks. A limiting piece is installed between the two second limiting grooves.

[0009] Preferably, the connecting member is provided with two through slots, the through slots are connected to the connecting slot, and the limiting rod is slidably fitted in the through slots.

[0010] Preferably, two slide grooves are provided on the connecting member, the slide grooves are connected to the through grooves, and the blocking pieces are slidably fitted in the slide grooves.

[0011] Preferably, a light hole is opened on the connecting piece, a pre-buried anchor bolt is connected in the light hole, the pre-buried anchor bolt thread is matched with a nut, and the C-shaped block is matched on the nut.

[0012] Preferably, an adjusting piece is installed between the two C-shaped blocks. The adjusting piece has a vertical cylinder with an adjusting groove in it. A slide cylinder is slidably fitted in the adjusting groove. The slide cylinder has a row of slots in which plug blocks are inserted.

[0013] Preferably, a clearance groove is provided on the vertical cylinder, and the insert block is slidably fitted in the clearance groove.

[0014] Preferably, a movable groove is provided in each of the two limiting blocks, and the movable groove is connected to the second limiting groove and is located at the top of the second limiting groove.

[0015] Preferably, the second limiting groove has a convex shape in a top view projection.

[0016] Preferably, the limiting member is slidably fitted in the movable groove.

[0017] Preferably, the limiting member comprises a transverse plate and a rectangular block, and the rectangular blocks are installed at both ends of the transverse plate.

[0018] The present invention has the following beneficial effects:

[0019] 1. Under the cooperation of the C-shaped block and the L-shaped block, the spring pushes the baffle to drive the limit rod to connect to the first limit groove to fix the L-shaped block, and then the C-shaped block can be used to limit the nut, effectively preventing the nut from rotating slightly due to external environmental factors such as wind pressure, temperature changes, building vibrations, etc. during long-term use, thereby avoiding the problem of loose connection, greatly improving the overall connection stability and safety of the curtain wall system, reducing connection failures caused by loose nuts, reducing the maintenance frequency and cost of the curtain wall system, and extending the service life of the curtain wall body, bringing long-term economic benefits to builders and owners;

[0020] 2. Under the action of the adjustment piece, when the distance between the two embedded anchor bolts is different, the slide tube slides to the specified position in the adjustment groove, and then the insert block is inserted into the slot to fix the slide tube, thereby completing the adjustment of the distance between the two C-shaped blocks. This avoids the problem that the C-shaped blocks cannot be installed due to different curtain wall systems or connectors at different positions in the same system, which may be caused by differences in design, construction or environmental factors. The adjustable nut limit structure can flexibly cope with these differences, ensuring that each connection point can achieve the best fastening effect, thereby enhancing the adaptability of the entire curtain wall system;

[0021] 3. With the cooperation of the limit pieces and the limit blocks, when the transverse keel is welded between the two vertical keels, the two sides of the transverse keel are respectively located in the two reserved grooves, and then the two limit blocks are fixed by the limit pieces, thereby ensuring the stability of the transverse keel after installation, effectively preventing its displacement or deformation caused by external factors, thereby improving the structural stability of the entire curtain wall system and avoiding the loosening of the two ends of the transverse keel connected to the vertical keels during use.
