Description

A stable connection device for building glass curtain walls

Technical field

The invention relates to the technical field of glass curtain wall connection devices, specifically a stable connection device for building glass curtain walls.

Background technique

With the development of technology and advancement of materials, glass curtain walls have gradually become a common outer envelope structure for high-rise buildings and large public buildings. The use of glass curtain walls breaks through the limitations of traditional masonry and concrete buildings and injects new elements and vitality into modern architecture. Architectural glass curtain walls refer to the form of curtain walls that are composed of glass panels and supporting structures and are suspended outside the main structure of the building. As an iconic element of modern high-rise buildings and urban landmarks, architectural glass curtain walls have significant advantages in improving building energy efficiency, reducing energy consumption, and enhancing artistic beauty;

The glass curtain wall connection device is a device used to connect glass curtain wall panels and supporting structures. It is an important part of modern high-rise buildings and large public buildings. There are generally three connection methods for glass curtain wall connection devices: load-bearing connection and semi-load-bearing connection. and non-load-bearing connections. Load-bearing connection means that the weight of the glass curtain wall is transferred to the main structure of the building through the connecting device. Semi-load-bearing connection means that part of the weight of the glass curtain wall is transferred to the main structure of the building through the connecting device. Non-load-bearing connection means that the glass curtain wall The weight is completely supported by itself and is not transferred to the main structure of the building.

For example, the Chinese authorized patent "A Connection Device for Building Glass Curtain Walls" with announcement number CN107246090B includes an adjustment box, a first glass curtain wall body and a second glass curtain wall body.

Compared with the prior art, the beneficial effects of the present invention are:

1. The present invention is provided with a connection claw position adjustment mechanism. When there is a position deviation between the connection claw and the installation hole of the glass curtain wall, the user can use a tool to turn the first adjustment knob, and the first adjustment knob can drive the worm to rotate. The contact surface between the worm and the worm gear forms a spiral friction transmission surface. The rotation of the worm drives the worm gear to rotate, and then drives the two first double-thread transmission rods to rotate through the worm gear. Under the friction with the first sliding block The rotational motion is converted into linear motion, so that the first sliding block drives the two adjustment seats to move synchronously toward the center or both sides, thereby realizing the adjustment of the lateral spacing of the connecting claws. By using a tool to turn the second adjustment knob, the second adjustment knob can The second double-threaded transmission rod is driven to rotate, and in cooperation with the second sliding block, the rotational motion is converted into linear motion, thereby driving the moving plate to move toward the center or both to achieve adjustment of the longitudinal spacing of the docking claws. With the cooperation of the base and the moving plate, the deviation distance between the connecting claw and the glass curtain wall installation hole can be adjusted reasonably and stably, thereby ensuring the flexibility of the installation of the connecting claw and the glass curtain wall, and avoiding forced fixation due to misalignment, resulting in stress Lack of concentration brings safety hazards to subsequent use, and at the same time solves the problem of rework, disassembly and assembly that affects the construction efficiency of the glass curtain wall.

2. The present invention provides a flexible fixing structure for the connecting claws. Before installing the glass curtain wall, it is necessary to first fix the connecting claws to the positioning holes of the glass curtain wall, drive the connecting claws from the rear end of the installation hole of the glass curtain wall, and then install the connecting claws on the glass curtain wall. The front end of the glass curtain wall installation hole is aligned with the annular threaded groove using a fastening cover, and the fastening cover and the connecting claw are fixed by rotation. Then the positioning screw is spirally passed through the fastening cover into the bottom of the annular threaded groove. into the screw hole to form a fixation between the connecting claw and the installation hole of the glass curtain wall. Then the glass curtain wall is erected so that the insertion rod at the rear end of the connecting claw corresponds to the insertion fixing barrel. During the process, the staff can adjust the position according to the deviation. Reasonable adjustment. During the insertion process, the inner hole of the plug-in fixed barrel will squeeze the limit rod, causing it to shrink into the internal storage groove. After the plug-in rod completely enters the plug-in fixed barrel, the staff needs to move the Insert the screwdriver into the slot on the upper end of the rotating rod. When it rotates, it will drive the insertion rod to rotate. When the position of the limit rod corresponds to the position of the limit slot, on the one hand, the insertion fixed barrel loses its squeeze on the limit rod. On the one hand, under the action of the support spring, the limit rod enters the inside of the limit slot to form a fixation of the plug-in fixing cylinder and the connecting claw. This structure uses a direct plug-in method to reduce the installation difficulty of the glass curtain wall and not only improves the It improves the installation efficiency and improves the installation firmness.

3. The present invention adopts a flexible disassembly structure of the plug-in fixed barrel and the plug-in rod. In order to avoid the glass curtain wall being damaged during use and needing to be replaced, the staff only need to use a tool to turn the third adjustment knob, and the third adjustment knob will drive the screw. Rotate, and under the friction between its external thread and the inner screw hole of the top block, in conjunction with the guide movement of the guide chute and the top block, the top block pushes the limit rod to move toward the inside of the storage slot until it is fully entered, and then the staff Turn the rotating rod to rotate the insertion rod to a set angle, so that the inner wall of the insertion fixed cylinder squeezes the limit rod again. Then the staff can directly pull the glass curtain wall outward to separate the glass curtain wall from the connecting device. This structure further Disassembly and assembly provide convenience, reduce construction difficulty, and also reduce the workload of staff.
