Description

Technical Field

[0001] The utility model relates to the technical field of construction ladder structures, in particular to a wedge-type quick-install ladder structure. Background Art

[0002] In the prior art, when carrying out construction, it is a difficult problem to connect floors where stairs have not been built or have not been solidified, and to connect floors separated by stairwells. In order to enable construction workers and construction materials to be transported in these separated places, the construction passages adopted in the prior art are varied. Some adopt the method of building a full-floor scaffolding for construction, some adopt the method of building a high-altitude horseway for construction, and some adopt a hanging basket for construction. However, the existing construction schemes have two problems. One is that the construction passage needs to be rebuilt every time a floor of stairs is built, which takes a long time; the other is that the construction passage often conflicts with the position of the stairs to be built, thereby hindering the construction of the stairs. This is particularly serious for prefabricated stairs that need to be hoisted as a whole. In addition, when building the scaffolding, the ladder therein usually adopts an integral structure, which cannot be disassembled and assembled, occupies a large space, is not convenient for construction and transportation, and has poor flexibility in use.

[0003] The Chinese utility model patent with application number: 202120516422.X discloses a quick-install temporary ladder, which is used to connect floors where stairs have not yet been built during stair construction. The staircase is a two-fold staircase; the temporary ladder is a straight ladder, and the upper end of the straight ladder is flush with the floor slab of the upper floor and the lower end is flush with the floor slab of the next floor; of the two sections of stairs to be repaired between the two floors connected by the temporary ladder, the staircase located in the lower half is called the lower half of the stairs to be repaired, and the temporary ladder is arranged above the lower half of the stairs to be repaired, and is arranged in the same direction as the lower half of the stairs to be repaired, and the lower end is hooked on the rest platform at the bottom of the lower half of the stairs to be repaired, and the upper end is hooked on the edge of the floor slab of the upper floor; the downward projections of the edges on both sides of the temporary ladder fall within the edges on both sides of the lower half of the stairs to be repaired. However, this type of quick-install temporary ladder can only be used in the process of stair construction, and cannot be applied to building platforms or scaffolding, and has certain usage restrictions. In addition, it adopts an integral structure and cannot be disassembled, occupies a large space, is not convenient for construction and transportation, and has poor flexibility in use.
