Description

Technical Field

[0001] This utility model relates to the field of curtain wall technology, and in particular to a connection mechanism for panel curtain wall construction. Background Technology

[0002] In the field of building curtain wall engineering, panel curtain walls are widely used due to their aesthetics, durability, and diverse decorative effects. To achieve reliable connections between different curtain wall panels, bolted connections have become a common method due to their convenient installation and clear force transmission. However, in actual engineering projects, due to factors such as dynamic loads on the building structure (e.g., wind, earthquakes, thermal expansion and contraction caused by temperature changes), environmental erosion (rainwater, humidity, corrosive gases), and long-term vibration, the connecting bolts between two sets of curtain walls are prone to loosening. Loose bolts can compromise the overall structural stability of the curtain wall, leading to panel displacement, detachment, and safety hazards. Summary of the Invention

[0003] The technical problem to be solved by this utility model is that the connecting bolts between the two sets of curtain walls in the existing technology are very easy to loosen. Loose bolts will destroy the overall structural stability of the curtain wall, causing the curtain wall panels to shift or fall off, resulting in safety hazards. To this end, we propose a panel curtain wall construction connection mechanism.

[0004] To achieve the above objectives, this application adopts the following technical solution: a panel curtain wall construction connection mechanism, including a pre-installed frame, and a first curtain wall body and a second curtain wall body installed on the outer wall of the pre-installed frame. A plug-in recess is fixedly connected to the outer wall of the first curtain wall body near the second curtain wall body, and a plug-in protrusion is fixedly connected to the outer wall of the second curtain wall body near the first curtain wall body.

[0005] The insertion recess has a groove inside, and the insertion protrusion matches the inner diameter of the groove. Both the insertion recess and the insertion protrusion have multiple sets of threaded holes on their outer walls. Each set of threaded holes in the insertion recess is provided with a bolt body, and each set of threaded holes in the insertion protrusion is provided with a reinforcing component.

[0006] Furthermore, when the insertion protrusion is fully inserted into the groove of the insertion recess, the threaded hole of the insertion recess completely coincides with the threaded hole of the insertion protrusion.

[0007] Furthermore, the reinforcing component includes a movable groove formed in the inner wall of the insertion protrusion, a movable block slidably connected to the inner wall of the movable groove, a movable rod fixedly connected to one end of the movable block, and a reinforcing block fixedly connected to the end of the movable rod away from the movable block.

[0008] Furthermore, the reinforcing block has an arc-shaped structure, matches the outer wall of the bolt body, and has a triangular side profile.

[0009] Furthermore, an elastic element is sleeved on the outer wall of the movable rod, and one end of the elastic element is fixedly connected to the reinforcing block.

[0010] Furthermore, when the reinforcing block is attached to the outer wall of the bolt body, the elastic element is in a compressed state.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this invention, the insertion protrusion is inserted into the groove of the insertion concave block, at which point the threaded holes are aligned, and the bolt body is screwed in to complete the initial tightening. During this process, the reinforcing component plays a key role. As the bolt body tightens, its outer wall gradually squeezes the reinforcing block, allowing the reinforcing block to overcome the resistance of the elastic element and drive the movable rod and movable block to slide in the movable groove. The elastic element is further compressed, generating a greater elastic reaction force. This reaction force pushes the reinforcing block to press tightly against the outer wall of the bolt body with greater pressure, forming a multi-directional clamping force, which effectively restricts the rotation and displacement of the bolt. This solves the problem that the connecting bolts between two sets of curtain walls are prone to loosening due to factors such as dynamic loads of the building structure, environmental erosion, and long-term vibration. Loose bolts will damage the overall structural stability of the curtain wall, leading to displacement and detachment of the curtain wall panels, causing safety hazards. Attached Figure Description

[0020] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0021] Please see Figures 1-5 To address the issue that the connecting bolts between two sets of curtain walls are prone to loosening due to factors such as dynamic loads on the building structure, environmental erosion, and long-term vibration, which can compromise the overall structural stability of the curtain wall, leading to panel displacement, detachment, and safety hazards, the following preferred technical solutions are provided:

[0022] The panel curtain wall construction connection mechanism includes a pre-installed frame 1, and a first curtain wall body 2 and a second curtain wall body 3 installed on the outer wall of the pre-installed frame 1. A plug-in recess 4 is fixedly connected to the outer wall of the first curtain wall body 2 near the second curtain wall body 3, and a plug-in protrusion 5 is fixedly connected to the outer wall of the second curtain wall body 3 near the first curtain wall body 2. The plug-in recess 4 has a groove 6 inside, and the inner diameter of the plug-in protrusion 5 matches that of the groove 6. Multiple sets of threaded holes 7 are opened on the outer walls of both the plug-in recess 4 and the plug-in protrusion 5. A bolt body 8 is provided at each set of threaded holes 7 of the plug-in recess 4, and a reinforcing component 9 is provided at each set of threaded holes 7 of the plug-in protrusion 5. When the plug-in protrusion 5 is fully inserted into the groove 6 of the plug-in recess 4, the threaded holes 7 of the plug-in recess 4 and the threaded holes 7 of the plug-in protrusion 5 are completely overlapped. When the plug-in protrusion 5 is inserted into the groove 6 of the plug-in recess 4, the threaded holes 7 are aligned, and the bolt body 8 is screwed in to complete the initial tightening.

[0023] The reinforcing component 9 includes a movable groove 91 formed in the inner wall of the insertion protrusion 5. A movable block 92 is slidably connected to the inner wall of the movable groove 91. A movable rod 93 is fixedly connected to one end of the movable block 92. A reinforcing block 94 is fixedly connected to the end of the movable rod 93 away from the movable block 92. The reinforcing block 94 has an arc-shaped structure and matches the outer wall of the bolt body 8. The side profile of the reinforcing block 94 has a triangular structure. An elastic element 95 is sleeved on the outer wall of the movable rod 93. One end of the elastic element 95 is connected to the reinforcing block 92. 4. When the reinforcing block 94 is attached to the outer wall of the bolt body 8, the elastic element 95 is in a compressed state. As the bolt body 8 is tightened, its outer wall gradually squeezes the reinforcing block 94, so that the reinforcing block 94 overcomes the resistance of the elastic element 95 and drives the movable rod 93 and the movable block 92 to slide in the movable groove 91. The elastic element 95 is further compressed, generating a greater elastic reaction force. This reaction force pushes the reinforcing block 94 to adhere tightly to the outer wall of the bolt body 8 with greater pressure, forming a multi-directional clamping force.

[0024] Specifically, when connecting the first curtain wall body 2 and the second curtain wall body 3, the insertion protrusion 5 is first inserted into the groove 6 of the insertion recess 4, at which point the threaded holes 7 are aligned, and the bolt body 8 is screwed in to complete the initial tightening. During this process, the reinforcing component 9 plays a key role. As the bolt body 8 is tightened, its outer wall gradually squeezes the reinforcing block 94, allowing the reinforcing block 94 to overcome the resistance of the elastic element 95, driving the movable rod 93 and the movable block 92 to slide in the movable groove 91. The elastic element 95 is further compressed, generating a greater elastic reaction force. This reaction force pushes the reinforcing block 94 to press tightly against the outer wall of the bolt body 8 with greater pressure, forming a multi-directional clamping force, effectively limiting the rotation and displacement of the bolt. This solves the problem that the connecting bolts between the two sets of curtain walls are prone to loosening due to the dynamic load of the building structure, environmental erosion, and long-term vibration. Loose bolts will damage the overall structural stability of the curtain wall, leading to displacement and detachment of the curtain wall panels, causing safety hazards.

[0025] When the building structure is subjected to dynamic loads (such as wind force, seismic force), environmental erosion, or long-term vibration, and the bolt body 8 tends to loosen, the reinforcing block 94, under the elastic restoring force of the elastic element 95, will continuously apply a reverse frictional force to the bolt, offsetting the external force that causes the bolt to loosen and firmly locking the bolt in its current position. At the same time, the cooperative structure of the insertion concave block 4 and the insertion protrusion block 5 forms a mechanical interlock between the two sets of curtain wall bodies, further dispersing the direct action of external forces on the bolt, reducing the risk of bolt loosening, thereby significantly improving the structural stability of the curtain wall connection and ensuring the long-term reliable operation of the building curtain wall.

[0026] Working principle: First, insert the protruding block 5 into the groove 6 of the inserting concave block 4. At this time, the threaded hole 7 is aligned. Screw in the bolt body 8 to complete the initial tightening. As the bolt body 8 is tightened, its outer wall gradually squeezes the reinforcing block 94, so that the reinforcing block 94 overcomes the resistance of the elastic element 95 and drives the movable rod 93 and the movable block 92 to slide in the movable groove 91. The elastic element 95 is further compressed, generating a greater elastic reaction force. This reaction force pushes the reinforcing block 94 to press tightly against the outer wall of the bolt body 8 with greater pressure, forming a multi-directional clamping force. When the building structure is affected by dynamic loads (such as wind force, earthquake force), environmental erosion, or long-term vibration, and the bolt body 8 has a tendency to loosen, the reinforcing block 94 will continuously apply a reverse friction force to the bolt under the action of the elastic restoring force of the elastic element 95, offsetting the external force that causes the bolt to loosen and firmly locking the bolt in the current position.

[0027] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
