Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to an external scaffolding wall connecting piece. Background Art

[0002] Steel structures offer significant advantages in terms of light weight, high strength, seismic resistance, and cost-effectiveness. They can be applied to large-span structures and are gradually becoming the primary building configuration. During steel structure construction, because steel structural components can be prefabricated in factories and installed quickly on-site, the lower steel structure can be inserted into the facade construction process after completion. External scaffolding is required for safety protection during facade construction. The external scaffolding is secured to the steel structure via wall ties, which typically feature steel beams on the outside. Conventional wall ties, which are in the form of columns or beams, are unstable, require a large amount of materials, and are costly to construct. Utility Model Content

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] like Figures 1 to 4 As shown, an external scaffolding wall connecting member provided by the present invention is used to connect an external scaffolding 7 to a steel beam 6 fixedly connected to the outside of a steel structure. The external scaffolding wall connecting member includes a steel member 2, a clamp 1, and a locking member 3. The clamp 1 is U-shaped and includes a first steel plate 11, a second steel plate 12, and a curved steel plate 13. One end of the first steel plate 11 is connected to one end of the second steel plate 12 by the curved steel plate 13. An opening 14 is formed between the other end of the first steel plate 11 and the other end of the second steel plate 12. The first steel plate 11, the second steel plate 12, and the curved steel plate 13 form a groove 15 that is connected to the opening 14 and is used to socket the steel beam 6. The locking member 3 is threadedly connected to the first steel plate 11 and can extend into the groove 15 after passing through the first steel plate 11.

[0024] Specifically, the steel beam 6 has a flange 61. The locking piece 3 vertically passes through the first steel plate 11, and the depth of the locking piece 3 inserted into the groove 15 can be adjusted. After the flange 61 of the steel beam 6 is inserted into the groove 15 through the opening 14 of the clamp 1, the locking piece 3 is adjusted to extend into the groove 15 to maintain constant pressure on the flange 61 of the steel beam 6, thereby stably fixing the clamp 1 to the steel beam 6. One end of the steel member 2 is fixedly connected to the clamp 1, and the other end of the steel member 2 is fixedly connected to the external scaffolding 7 via the snap fastener 8, so that the external scaffolding 7 can be installed on the steel structure through the wall connection.

[0025] As an embodiment, the steel component 2 is welded and fixed to the first steel plate 11 on the clamp 1. Specifically, the steel component 2 is a steel pipe, and two parallel ribs 5 are welded to the lower end of the first steel plate 11. One end of the steel component 2 is arranged between the two ribs 5 and welded and fixed to the ribs 5 to stably connect the steel component 2 to the clamp 1.

[0026] As an embodiment, the locking piece 3 is threadedly connected to the first steel plate 11. Specifically, the locking piece 3 is a bolt. Two nuts 4 are welded on the side of the first steel plate 11 away from the second steel plate 12, and a through hole is opened on the first steel plate 11 at the position corresponding to the nut 4. The locking piece 3 passes through the nut 4 and the through hole in sequence. The steel component 2 is located in the middle of the lower end of the first steel plate 11, and the two nuts 4 are located on both sides of the steel component 2. The screw rod 813 ends of the two bolts located on both sides of the steel component 2 pass through the nut 4 and the first steel plate 11 and extend into the groove 15 to press on the flange 61 of the steel beam 6 placed in the groove 15, further improving the stability of the clamp fixed on the steel beam 6.

[0027] In the above embodiment, one end of the fastener 8 is sleeved on the steel member 2, and the other end of the fastener 8 is sleeved on the outer scaffold 7. Specifically, the fastener 8 includes two locking assemblies 81 that can be rotatably connected to each other, and the two locking assemblies 81 are sleeved on the steel member 2 and the outer scaffold 7 respectively.

[0028] As an embodiment, the locking assembly 81 includes a first clamping member 811, a second clamping member 812, a screw 813, and a nut 814. The two first clamping members 811 on the two locking assemblies 81 are rotatably connected to each other via a rivet, one end of the second clamping member 812 is rotatably connected to one end of the first clamping member 811 via a shaft, one end of the screw 813 is rotatably connected to the other end of the first clamping member 811, and the other end of the screw 813 rotatably passes through the other end of the second clamping member 812 and is threadedly connected to the nut 814. Thus, the first clamping member and the second clamping member on one of the locking assemblies 81 can be mutually clamped on the steel member 2, and the screw 813 is rotated through the second clamping member and tightened by the nut 814, so that the first clamping member and the second clamping member are mutually tightened and clamped to the steel member 2. Rotate the other locking assembly 81, use the first clamping piece and the second clamping piece to clamp each other on the outer scaffolding 7, and use the screw 813 to rotate through the second clamping piece, and tighten it through the nut 814, so that the first clamping piece and the second clamping piece are tightened and clamped to the outer scaffolding 7, thereby stably fixing the steel member 2 and the outer scaffolding 7 to each other.

[0029] In summary, the present invention is to set a "U"-shaped clamp 1 on the steel beam 6 so that the flange 61 of the steel beam 6 is placed in the groove 15, so that the clamp 1 can be hung on the flange 61 of the steel beam 6, and the locking piece 3 is threadedly connected to the first steel plate 11 on the clamp 1, and extends through the first steel plate 11 into the groove 15 to abut against the flange 61 of the steel beam 6, so that the clamp 1 can be stably hung on the steel beam 6, and one end of the steel member 2 is fixedly connected to the clamp 1, and the other end of the steel member 2 is fixedly connected to the external scaffolding 7 through the snap-fit ​​member 8, so that the external scaffolding 7 can be stably installed on the steel beam 6 outside the steel structure. It has a simple structure, good stability, and is easy to install and disassemble. The external scaffolding wall connecting member can be installed and dismantled by a single worker, which is conducive to reducing construction time and improving construction efficiency. In addition, the external scaffolding wall connecting member can be used in a cyclical manner after being dismantled, reducing material waste during construction and reducing construction costs. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
