Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a climbing frame attachment connector used for a bay window. Background Art

[0002] The existing attached climbing frame refers to a scaffolding that is erected at a certain height and attached to the engineering structure. It relies on its own lifting equipment and devices to climb or descend layer by layer with the engineering structure. It is an external scaffolding with anti-overturning and anti-falling devices, which turns high-altitude operations into low-altitude operations and suspended operations into operations inside the frame.

[0003] At present, the attached lifting scaffolding needs to be moved upward again after each floor height increase to continue to keep the climbing frame outside the construction surface. When the climbing frame is lifted and lowered, the part connected to the building needs to bear the load when the climbing frame is climbing, and the stability requirement is high. However, the protruding air conditioning panels or bay window panels on the exterior walls of buildings are not convenient for the installation of climbing frame guide rails and anti-fall systems. When the wall-mounted support of the climbing frame needs to be installed at the bay window position, since the attachment surface at the bay window is far away from the frame body, the wall-mounted support cannot be directly placed at the corresponding position, and an extended bracket is required for connection.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0059] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0060] The inventors have discovered that existing attachment connectors for bay windows generally use inclined tie rods to strengthen the connection between the wall-mounted support and the building wall. During the construction process, a large amount of mechanical vibration will be generated when various machines are working and the climbing frame is climbing, which will cause the tie rods to wear. After long-term use, the tie rods will be at risk of breaking, thereby making it impossible to ensure the safety of the climbing frame, posing a major hidden danger to the construction.

[0061] Based on this, the utility model provides a climbing frame attachment connector for a bay window position, which is described in detail below through specific embodiments.

[0062] The utility model embodiment provides a climbing frame attachment connector for a bay window position, referring to Figure 1-3 As shown, it includes a wall-mounted support 1, a pull rod 2 and a wall-mounted hinged seat 3;

[0063] The wall-attached hinge seat 3 comprises a first wall-attached plate 31 and two first ear plates 32 fixed to the first wall-attached plate 31, and a first elastic member 33 is arranged on one side of the first ear plate 32 close to the center of the first wall-attached plate 31;

[0064] The wall-attached support 1 comprises a second wall-attached plate 11, a support body 12 and two second ear plates 13; the second wall-attached plate 11 is fixed to the end of the support body 12, the two second ear plates 13 are symmetrically fixed to the two sides of the support body 12, and a second elastic member 14 is provided on one side of the second ear plate 13 close to the center of the support body 12;

[0065] The first wall-attached panel 31 and the second wall-attached panel 11 can be fixedly connected to the building wall, the first wall-attached panel 31 is located directly above the second wall-attached panel 11, the upper end of the pull rod 2 is hinged between the two first ear plates 32, and respectively squeezes the two first elastic members 33, and the lower end of the pull rod is hinged between the two second ear plates 13, and respectively squeezes the two second elastic members 14.

[0066] In an embodiment of the present invention, a climbing frame attachment connector for a bay window position is provided. By arranging a first elastic member 33 on the inner side of the first ear plate 32 and a second elastic member 14 on the inner side of the second ear plate 13, when the pull rod 2 is hinged between the wall-mounted hinge seat 3 and the wall-mounted support 1, the upper end of the pull rod 2 is clamped between the two first elastic members 33, and the lower end of the pull rod 2 is clamped between the two second elastic members 14, so that the first elastic member 33 and the second elastic member 14 can absorb the vibration of the pull rod 2 in time. Under the elastic buffering effect of the first elastic member 33 and the second elastic member 14, the vibration of the pull rod 2 is effectively reduced, thereby reducing the wear of the pull rod 2 and greatly reducing the risk of disconnection of the pull rod 2, providing protection for construction safety. At the same time, it can also increase the service life of the pull rod 2 and the attachment connector, saving construction costs.

[0067] In an alternative embodiment, referring to Figure 1 and Figure 4 As shown, the pull rod 2 includes a telescopic rod 21 and an upper hinge 22 and a lower hinge 23 respectively fixed to both ends of the telescopic rod 21. The upper hinge 22 is hinged to two first ear plates 32 and is located between two first elastic members 33, and the lower hinge 23 is hinged to two second ear plates 13 and is located between two second elastic members 14. Figure 4 As shown, a retractable protective cover 24 is provided at one end of the upper hinge 22 close to the telescopic rod 21. The length of the protective cover 24 after extension is greater than or equal to the length of the telescopic rod 21. When the protective cover 24 is fully extended, the telescopic rod 21 can be wrapped therein, thereby preventing the telescopic rod 21 from being corroded by pollutants such as concrete chips, dust and moisture, further avoiding damage to the pull rod 2 and extending the service life of the pull rod 2.

[0068] In an alternative embodiment, referring to Figure 1 , Figure 4 and Figure 5 As shown, the protective cover 24 includes a flexible cover body 242 and a positioning ring 241 and an elastic ring 243 respectively arranged at both ends of the flexible cover body 242. The positioning ring 241 is fixed to one end of the upper hinge 22 close to the telescopic rod 21, and the positioning ring 241, the flexible cover body 242 and the elastic ring 243 are all sleeved on the telescopic rod 21, and the flexible cover body 242 can be freely extended and retracted along the telescopic rod 21. Figure 5As shown, when the length adjustment of the telescopic rod 21 is completed, the flexible cover body 242 can be extended, and the elastic ring 243 at the end of the flexible cover body 242 flexibly moves with the cover body to the end of the telescopic rod 21 close to the lower hinge 23, so that the telescopic rod 21 is completely wrapped, effectively protecting the telescopic rod 21 from corrosion. The inner diameter of the elastic ring 243 in the unstretched state is smaller than the outer diameter of the end of the telescopic rod 21 close to the lower hinge 23. When the flexible cover body 242 is extended to wrap the telescopic rod 21, the elastic ring 243 tightly surrounds the end of the telescopic rod 21, so that the wrapping is more sealed and not easy to shift. The material of the flexible cover body 242 includes but is not limited to relatively soft waterproof materials such as PVC plastic, nylon and polyester.

[0069] In an alternative embodiment, referring to Figure 1 and Figure 4 As shown, the telescopic rod 21 includes a threaded sleeve 211, a positive thread screw 212 and a negative thread screw 213. The internal thread directions at both ends of the threaded sleeve 211 correspond to the external thread directions of the positive thread screw 212 and the negative thread screw 213, respectively. The two ends of the threaded sleeve 211 are respectively sleeved and threadedly connected to the positive thread screw 212 and the negative thread screw 213. When the positive thread screw 212 and the negative thread screw 213 are not rotated, the length of the telescopic rod 21 can be adjusted by rotating the threaded sleeve 211 in the middle, thereby adjusting the length of the pull rod 2, thereby enhancing the applicability of the pull rod 2 in different bay window sizes.

[0070] In this embodiment, refer to Figure 1 and Figure 4 As shown, one end of the positive thread screw 212 away from the threaded sleeve 211 is fixedly connected to the upper hinge 22, and one end of the reverse thread screw 213 away from the threaded sleeve 211 is fixedly connected to the lower hinge 23. When the upper hinge 22 is hinged to the wall hinge seat 3 and the lower hinge 23 is hinged to the wall support 1, the thread resistance torque between the threaded sleeve 211 and the positive thread screw 212 and the reverse thread screw 213 is mainly relied on to ensure that the pull rod 2 is not disconnected. Since the first elastic member 33 and the second elastic member 14 can absorb the mechanical vibration of the two ends of the pull rod 2 in time, the thread wear of the threaded sleeve 211, the positive thread screw 212 and the reverse thread screw 213 can be effectively reduced, the risk of the pull rod 2 being disengaged can be reduced, and the stability of the pull rod 2 is improved, thereby ensuring the safe use of the pull rod 2 while achieving the adjustable length of the pull rod 2 and increasing the service life of the pull rod 2. Furthermore, since the protective cover 24 can completely wrap the telescopic rod 21, it can effectively prevent pollutants from corroding the threaded sleeve 211, the positive thread screw 212 and the negative thread screw 213, and further avoid damage to the threads of the threaded sleeve 211, the positive thread screw 212 and the negative thread screw 213, thereby further ensuring the stability and safety of the pull rod 2, thereby ensuring that the climbing frame attachment connector can stably support the climbing frame.

[0071] In an alternative embodiment, referring to Figure 1 and Figure 4 As shown, the pull rod 2 also includes a rotating handle 25 that is detachably inserted in the middle of the threaded sleeve. The threaded sleeve can be rotated more easily by rotating the handle 25, thereby improving the efficiency of adjusting the length of the telescopic rod 21. After the length of the telescopic rod 21 is adjusted, if the protective cover 24 is to be extended, the rotating handle 25 can be pulled out, and after the protective cover 24 is fully extended, the rotating handle 25 can be put into the protective cover 24.
