Description

Technical Field

[0001] The utility model relates to a telescopic wall-attached rod recovery device, belonging to the technical field of building construction. Background Art

[0002] The traditional way of connecting scaffolding with wall attachments is to use steel pipes for pre-embedding and connect them to the scaffolding through fasteners. When the scaffolding is removed, the pre-embedded steel pipes are hollow and need to be filled, which undoubtedly increases the amount of repair work. At the same time, the repaired parts are prone to water seepage, resulting in quality defects. In addition, in engineering construction, some dead corners where steel pipes cannot be pre-embedded need to be welded with steel plates and steel pipes and fixed to the concrete structure with expansion screws. This operation not only consumes engineering work but also has the risk of material waste.

When the fastener 5 is connected to the scaffolding 2, relative rotation between the short rod 31 and the long rod 32 can be prevented, thereby affecting the structural stability of the scaffolding 2.

[0026] Furthermore, an inner wall of the connecting hole 311 is provided with an internal thread, and an outer surface of the connecting head 321 is provided with an external thread that matches the internal thread. When the long rod 32 is rotated, the connecting head 321 moves forward or backward in the connecting hole 311 through the cooperation between the external thread and the internal thread, thereby adjusting the sum of the lengths of the short rod 31 and the long rod 32, and adapting it to different distances between the scaffolding 2 and the concrete structure 1 through convenient operation.

[0027] Furthermore, the fastener 5 includes a U-shaped fixed hoop plate 51 and a rotating hoop plate 52, and the arc surfaces of the fixed hoop plate 51 and the rotating hoop plate 52 are arranged relatively to form a clamping space for clamping the rod body 21 of the scaffolding 2; wherein, the middle part of the fixed hoop plate 51 is fixedly connected to the end of the long rod 32, and the fixed connection method can be welding, or the fixed hoop plate 51 and the long rod 32 are integrally formed; one end of the fixed hoop plate 51 is hinged to the adjacent end of the rotating hoop plate 52 through a rotating shaft, and the other end of the fixed hoop plate 51 is fixedly connected with a bolt 53. When the fixed hoop plate 51 and the rotating hoop plate 52 enclose the clamping rod body 21, the bolt 53 passes through the hole 54 at the end of the rotating hoop plate 52 adjacent to it and is locked with the nut 55, thereby fixing the fastener 5 to the rod body 21 and limiting the rotation of the long rod 32 to affect the stability of the scaffolding 2.

[0028] The working principle of this utility model:

[0029] See also Figure 1-6, the utility model corresponding to the position of the rod body 21 arranged vertically along the scaffold 2 is arranged at intervals in the height direction, and each utility model is arranged in the following manner: the connecting member 3 is placed horizontally between the concrete structure 1 and the scaffold 2, so that the fixing seat 4 fixedly connected to the short rod 31 fits with the concrete structure 1, and a plurality of expansion bolts 42 are respectively passed through the through holes 41 adjacent thereto and then screwed into the concrete structure 1, so that the fixing seat 4 is fixedly connected to the concrete structure 1, and the connecting head 321 of the long rod 32 is inserted into the connecting hole 311 of the short rod 31, and the long rod 32 is rotated at the same time to connect the short rod 31 and the long rod 32 and adjust the connection The head 321 is inserted into the depth of the connecting hole 311, thereby adjusting the sum of the lengths of the short rod 31 and the long rod 32 to adapt to the different distances between the concrete structure 1 and the scaffolding 2. When the fastener 5 is close to the rod body 21 of the scaffolding 2, the rotating hoop plate 52 is swung to enclose it with the fixed hoop plate 51 to form a clamping space for clamping the adjacent rod body 21. At the same time, the bolt 53 on the fixed hoop plate 51 passes through the hole 54 on the rotating hoop plate 52 and is locked with the nut 55 to complete the connection between the connecting piece 3 and the scaffolding 2, and can prevent the long rod 32 and the short rod 31 from rotating relative to each other, thereby increasing the load-bearing capacity of the scaffolding 2 and maintaining its stability.

[0030] When the construction work is completed, the nut 55 is rotated to separate the fixed hoop plate 51 and the rotating hoop plate 52 from the adjacent rod body 21; the long rod 32 is rotated to separate the long rod 32 from the short rod 31, the expansion bolts 42 are unscrewed, and the fixing seat 4 is removed, thereby realizing the disassembly of the utility model for secondary use.
