All-steel attached type lifting scaffold free end ultrahigh rear embedded part device

Abstract

The utility model discloses an all-steel attached type lifting scaffold free end superelevation rear embedded part device which is characterized in that according to building characteristics, a prefabricated diagonal member is planned to be in rigid connection with a climbing frame guide rail, and it is guaranteed that the height of the free end of a climbing frame is lower than 6 m. When the floor height of an operation layer is 5.4 m (a non-standard layer), the height of the free end of the climbing frame is 5.4 m (floor height) + 1.5 m (protection height) = 6.9 m, and the free end of the climbing frame conflicts with the situation that the height of a cantilever of a frame body is not larger than 2 / 5 of the height of the frame body and is not larger than 6 m in 4.4.8 of Safety Technical Specification of Building Construction Tool Scaffold JGJ202-2010. Under the condition, along with the height change of different floors, the embedded parts can be installed under the safe distance required by specifications, and then the safety and stability of the frame body are guaranteed.

Description

Technical Field

[0001] The utility model relates to the field of shear wall scaffolding implementation, in particular to a free end super-high rear embedded component device of a full-steel attached lifting scaffolding. Background Art

[0002] At present, there are many shear walls in the core tube area, and most of the attachment positions are located at the shear wall position. Conventional treatment measures such as inclined steel wire ropes and pre-embedded additional wall ties on the plate are not easy to implement. When the height of the working layer is 5.4m (non-standard layer), the height of the free end of the climbing frame is 5.4m (layer height) + 1.5m (protection height) = 6.9m. The free end of the climbing frame conflicts with Article 4.4.8 of the "Technical Specifications for Safety of Tool-type Scaffolding in Construction" JGJ202-2010, which states that "the cantilever height of the frame shall not be greater than 2 / 5 of the frame height and shall not be greater than 6m". Conventional treatment measures such as inclined steel wire ropes and pre-embedded additional wall ties on the plate are difficult to meet its requirements. Utility Model Content

[0005] According to the utility model, a super-high rear embedded component device for the free end of a full-steel attached lifting scaffold is characterized in that the rear embedded component is a galvanized steel plate with a specification of 200*200*10.

[0006] According to the utility model, a super-high rear embedded device for the free end of a full-steel attached lifting scaffold is characterized in that the steel pipe is a Φ48.3*3.6 steel pipe.

[0007] The utility model has the following advantages: the utility model provides an ultra-high post-embedded device for the free end of an all-steel attached lifting scaffold. According to the characteristics of the building, it is planned to use prefabricated inclined rods to be rigidly connected to the guide rails of the climbing frame to ensure that the height of the free end of the climbing frame is less than 6m. When the height of the working layer is 5.4m (non-standard layer), the height of the free end of the climbing frame is 5.4m (layer height) + 1.5m (protection height) = 6.9m. The free end of the climbing frame conflicts with Article 4.4.8 of the "Technical Specifications for Safety of Tool Scaffolds in Construction" JGJ202-2010, "The cantilever height of the frame shall not be greater than 2 / 5 of the frame height, and shall not be greater than 6m".

[0012] The following will be combined with the attached Figure 1-Figure 3 The utility model is described in detail, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0013] The utility model provides an ultra-high post-embedded device for the free end of a full-steel attached lifting scaffold, as shown in the figure, comprising a post-embedded device 1 and a steel pipe 2, the post-embedded device 1 being fixed to the wall by bolts, an oblique pull rod being welded by the post-embedded device 1 and the steel pipe 2, and when the climbing frame encounters a 5.4m floor, four 10# post-cut bolts are used to connect it to the wall at the position of the poured shear wall, the front end of the steel pipe 2 is connected to the climbing frame guide rail by a fastener, the connection height is greater than 900mm, and the height of the free end of the climbing frame is ensured to be less than 6m.

[0014] In the present application, the post-embedded part 1 is a galvanized steel plate with a specification of 200*200*10.

[0015] In the present application, the steel pipe 2 is a Φ48.3*3.6 steel pipe.

[0016] The specific implementation of this application is described in detail below;

[0017] The height of the all-steel frame is 19.5 meters, covering 4.5 standard floors. When the height of the working floor is 5.4m (non-standard floor), the height of the free end of the climbing frame is 5.4m (floor height) + 1.5m (protection height) = 6.9m. The free end of the climbing frame conflicts with Article 4.4.8 of "Safety Technical Specifications for Tool-type Scaffolding in Construction" JGJ202-2010, which states that "the cantilever height of the frame shall not be greater than 2 / 5 of the frame height and shall not be greater than 6m."

[0018] When this patent is implemented;

[0019] 1. On-site technicians will measure and lay out the actual distance of the climbing frame guide rail (wall shrinkage due to floor changes) to ensure that the connection between the upper end of the wall connection and the climbing frame guide rail is 900mm higher than the floor elevation.

[0020] 2. Use 200×200×10 galvanized steel plate and Φ48.3*3.6 steel pipe to weld a tool-type diagonal pull rod. When the climbing frame encounters a 5.4m floor, use 4 10# post-cut bolts to connect it to the wall at the position of the poured shear wall. The front end of the steel pipe is connected to the climbing frame guide rail with fasteners. The connection height is greater than 900mm to ensure that the height of the free end of the climbing frame is less than 6m.

[0021] This patent has the following advantages and beneficial effects: When the height of the working layer is 5.4m (non-standard layer), the height of the free end of the climbing frame is 5.4m (layer height) + 1.5m (protection height) = 6.9m, and the free end of the climbing frame conflicts with Article 4.4.8 of the "Technical Specifications for Safety of Tool-type Scaffolding in Construction" JGJ202-2010, which states that "the cantilever height of the frame shall not be greater than 2 / 5 of the frame height and shall not be greater than 6m". In this case, as the height of different floors changes, embedded parts can be installed at the safe distance required by the specification, thereby ensuring the safety and stability of the frame.

[0022] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
