Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a high-altitude working platform outside a shear wall. Background Art

[0002] Temporary aerial work platforms have become the most economical and convenient choice in construction, but the installation conditions are becoming more and more complex and the usage scenarios are becoming more and more extensive. Conventional access equipment can no longer meet the requirements of most construction sites. Therefore, based on standard products, various non-standard installation and combination methods of temporary suspended access equipment have emerged according to the different requirements and characteristics of each project.

[0003] At present, temporary aerial work platforms have been widely used in the process of building exterior wall construction. However, due to construction period and other reasons, the roof of some locations does not meet the conditions for placing a hanging mechanism for the aerial work platform to take root during exterior wall construction. Especially in the position of solid shear walls, the hanging mechanism cannot extend from windows and other structures, and all common installation methods cannot be used in such working conditions. Utility Model Content

[0010] Preferably, separate through holes equal in number to the pulling wire ropes are opened on the top of the shear wall, and the diameter of the through holes is not less than twice the diameter of the pulling wire ropes.

[0013] Preferably, a safety rope is provided for tying up construction workers in the aerial work platform, and the safety rope is fixed on the roof or tied to a building column.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model solves the problem of exterior wall construction when the roof at the shear wall position is not completed or does not meet the installation conditions of the aerial work platform suspension mechanism by directly setting the cantilever beam on the outside of the solid shear wall and installing the climbing wire rope in conjunction with the buried plate set on the inside of the solid shear wall;

[0016] 2. The utility model simplifies the materials and simplifies the complex components of the traditional suspension mechanism into a single cantilever beam, which saves materials and greatly shortens the installation time;

[0022] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0023] like Figure 1 As shown, as the utility model of the shear wall outer aerial work platform, the shear wall 6 inner lower part is fixed with an embedded plate 8 through a fixing member 9, the outer upper part of the shear wall 6 is fixed with a cantilever beam 1 through a fixing member 9, the upper part of the shear wall 6 is provided with three through holes 5 at the same level, the bottom of the through hole 5 is fixed with a protective sleeve 4, and the top of the embedded plate 8 is provided with three climbing wire ropes 2 through a basket bolt 7, as shown in FIG. Figure 2 As shown, three climbing wire ropes 2 pass through three through holes 5 and converge at the end of the cantilever beam 1 vertically downward. Wire rope clamps 3 are provided on both sides of the climbing wire ropes 2. An aerial work platform 10 is provided at the ends of the three climbing wire ropes 2 located below the cantilever beam 1. By directly setting the cantilever beam 1 on the outside of the solid shear wall 6 and installing the climbing wire ropes 2 in conjunction with the buried plate 8 set on the inside of the solid shear wall 6, the problem of exterior wall construction when the roof at the position of the shear wall 6 is not completed or does not meet the installation conditions of the aerial work platform 10 suspension mechanism is solved. The climbing wire rope 2 is pre-tightened by the basket bolt 7, and the friction between the climbing wire rope 2 and the shear wall 6 is reduced by the protective cover 4 to avoid unnecessary damage to the shear wall 6.

[0024] The angle between the two farthest climbing wire ropes 2 located at the end of the cantilever beam 1 is not less than 30 degrees. The angle between the two farthest climbing wire ropes 2 is not less than 30 degrees to ensure that the spacing between the climbing wire ropes 2 is sufficient, and the coverage range is large, thereby improving the stability of the device. The diameter of the through hole 5 is not less than twice the diameter of the climbing wire rope 2. The larger through hole 5 is convenient for the passage of the climbing wire rope 2 on the one hand, and provides space for the climbing wire rope 2 to move on the other hand. The horizontal height of the cantilever beam 1 is at least 10 cm lower than the horizontal height of the through hole 5. The height difference prevents the climbing wire rope 2 from sticking to the cantilever beam 1, thereby reducing friction and saving effort. The cantilever beam 1 is lower than the through hole 5, and the climbing wire rope 2 will squeeze the cantilever beam 1 towards the shear wall 6 when subjected to force, thereby improving the stability of the cantilever beam 1, and then improving the stability of the device.

[0025] Inclined stiffening plates are provided on both the upper and lower sides of the end portion where the cantilever beam 1 contacts the shear wall 6. One end of the stiffening plate is welded to the cantilever beam 1 and the other end is fixed to the outside of the shear wall 6 through a fixing member 9. The stiffening plate improves the stability of the cantilever beam 1. When the cantilever beam 1 is pressed downward, the two stiffening plates provide support force to the cantilever beam 1, thereby increasing the stability of the cantilever beam 1 when subjected to force. The cantilever beam 1 can be set as square steel. A suspension head 11 is provided at the end of the cantilever beam 1. Three climbing steel wire ropes 2 converge on the suspension head 11 and extend vertically downward. The three climbing steel wire ropes 2 are converged and guided through the suspension head 11, thereby improving the stability of the climbing steel wire ropes 2 and thereby improving the aerial work platform 10. Stability, the cantilever beam 1 can also be set as an I-beam, and three climbing wire ropes 2 converge on the inner side of the end of the cantilever beam 1. The climbing wire rope 2 is limited by the hollow inside the end of the I-beam, eliminating the suspension head 11, reducing the counterweight, thereby improving the bearing capacity of the device and reducing the cost. A safety rope 12 is also provided for binding the construction workers in the aerial work platform 10. The safety rope 12 is fixed on the roof or tied to the building column. By fixing the safety rope 12 on a separate stable structure and then connecting it to the construction workers, a protection is provided for the construction workers, avoiding danger to the construction workers when the aerial work platform 10 falls, thereby improving safety.

[0026] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
