Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to the field of auxiliary construction equipment for eaves and parapet walls of cantilevered buildings, specifically to an auxiliary tool for cantilevered building structure operations. Background Technology

[0002] In the field of architecture, cantilever structures such as eaves and parapets (parapet walls built on the outermost edge of the building's roof) are important components of the building's facade. The construction of the outer side of these cantilever structures is required, and the quality of the construction directly affects the building's aesthetic effect and durability.

[0003] However, due to the cantilevered structure, the limited working area renders large machinery useless, forcing workers to operate with great difficulty in the confined space. Moving tools and materials becomes extremely cumbersome, and even the slightest mistake could result in collisions with surrounding structures, affecting construction quality. Furthermore, the risks of working at heights are ever-present; the arrangement and maintenance of safety measures are fraught with difficulties, and every bending or raising of a hand carries the potential danger of falling or objects dropping. Utility Model Content

[0004] This utility model provides an auxiliary tool for working on cantilevered building structures, solving the problems of difficult and unsafe work on the outside of eaves, parapet walls, and other cantilevered building structures. It allows the working part and the support part to span across both sides of the top surface of the cantilevered building structure, improving the working environment on the outside of eaves, parapet walls, etc., and providing workers with a safer, more efficient, and more convenient working platform.

[0005] This utility model is achieved through the following technical solution:

[0006] An auxiliary tool for constructing cantilevered building structures, comprising:

[0007] The work unit includes a vertical ladder with a bottom platform extending laterally outward at its base and a top platform distributed laterally at its top. The bottom surface of the top platform is equipped with supporting rollers that move on the cantilevered roof surface of the building structure.

[0008] The support includes a vertical bracket, the top of which is fixedly connected to the end of the top platform away from the vertical ladder.

[0009] Furthermore, the vertical ladder is provided with multiple auxiliary rollers I on the surface near one side wall of the cantilevered building structure.

[0010] Furthermore, the vertical support is provided with multiple auxiliary rollers II on the surface near the other side wall of the cantilevered building structure.

[0011] Furthermore, the bottom of the vertical support is provided with a connecting plate that extends laterally outward, and the connecting plate is provided with multiple counterweights.

[0012] Furthermore, the top of the vertical support is provided with an adjustable cross brace, and the transverse connecting plate is provided with multiple adjustment holes along the length direction. The adjustable cross brace is fixed to the top platform through the adjustment holes and bolt assembly.

[0013] Furthermore, the outer side of the vertical ladder is provided with multiple semi-circular guardrails along the height direction, and diagonal bracing is provided between the bottom platform and the vertical ladder.

[0014] The beneficial effects achieved by this utility model compared with the prior art are as follows:

[0015] 1. The auxiliary tool for working on cantilevered building structures described in this utility model includes a working part and a supporting part. When working on cantilevered building structures such as parapet walls or vertical eaves, the working part and the supporting part are fixed and operated on both sides of the top surface of the cantilevered building structure, respectively.

[0017] 3. When the overall auxiliary tools move, auxiliary rollers I and II cause the vertical ladder and vertical support to roll and rub against the inner and outer sides of the building structure, thus avoiding damage to the wall surface;

[0018] 4. Easy assembly: It adopts a combination of pre-assembled modules and on-site rapid splicing mode. Construction workers can complete the overall construction in a very short time by connecting with anchor bolts.

[0028] Example 1

[0029] like Figure 1-3As shown, this embodiment discloses an auxiliary tool for working on cantilevered building structures, mainly comprising a working section and a support section. The working section includes a vertical ladder 1, a bottom platform 2, and a top platform 3, all welded from steel frames. The bottom platform 2 is fixed to the bottom of the vertical ladder 1 by welding or bolting and extends laterally outward. The top platform 3 is laterally fixed to the top of the vertical ladder 1, and support rollers 4, which can move on the top surface of the cantilevered building structure, are installed on the bottom surface of the top platform 3. The working section is the operating platform of the auxiliary tool, located on the outer side of the cantilevered building. The working section is specially equipped with a set of support rollers 4. With the help of these support rollers 4, the working platform can move smoothly and efficiently laterally along the concrete eaves and parapet wall top surface within a limited space, accurately reaching various points required for the operation, greatly expanding the operational coverage and improving operational flexibility. Three sets of auxiliary rollers Ⅰ7 are installed on the surface of the vertical ladder 1 near one side wall of the cantilevered building structure to achieve positioning support and assist in the movement of the support rollers 4. To improve the safety of the work area, multiple semi-circular guardrails are welded along the height direction on the outside of the vertical ladder 1, and two diagonal bracing rods are fixed between the bottom platform 2 and the vertical ladder 1.

[0030] The support unit includes a vertical bracket 5, with two adjustable cross braces 6 welded to the top of the vertical bracket 5. Multiple adjustment holes 8 are machined along the length of the transverse connecting plate. The adjustable cross braces 6 are fixed to the top platform 3 via the adjustment holes and bolt assemblies. This design allows for longitudinal adjustment between the working unit and the support unit, enabling its application to cover various sizes of cantilever structures and meet the needs of construction operations in different areas. Three sets of auxiliary rollers II 9 are installed on the vertical bracket 5 near the opposite side wall of the cantilever building structure. The support unit serves as a support system for auxiliary working tools, connected to the working unit via the adjustable cross braces 6 at the front, and fixed and movable via the auxiliary rollers II 9 and I 7.

[0031] like Figure 4 As shown, taking construction work on a parapet wall or eaves at an outward-protruding section as an example, the work area and support structure are positioned across the top surface of the outward-protruding building structure, with the work area on the outside of the wall and the support on the inside. Workers first attach their safety belts to the support structure before entering the work area to begin work. After completing one section, with the assistance of workers above, the auxiliary tools are moved, and the workers then move to the next section to continue construction. Workers can use the tools for tasks such as concrete repair on the outward-protruding eaves, pipeline installation, putty application, and maintenance of nearby power lines. This improves the working environment at eaves and parapet walls, providing workers with a safer, more efficient, and convenient working platform.

[0032] For example, the platform canopy of the Rizhao Railway Station passenger facility renovation project adopted a concrete cantilever structure with an eave height of 700mm. The total length of the four platforms is 4400m. Concrete retaining walls with a height of 1200mm were installed on the east and west sides of the waiting level. This technology, after careful construction, has received unanimous praise from all parties. While shortening the construction period and ensuring quality and safety, it also saved costs and has promotional value.

[0033] Example 2

[0034] like Figure 1 As shown, this embodiment also discloses an auxiliary tool for working on cantilevered building structures. For situations where the height of the parapet wall or vertical eaves is relatively small, a counterweight is added to the bottom of the support. Specifically, a connecting plate 10 extending laterally outward is installed at the bottom of the vertical support 5, and multiple counterweights 11 are provided on the connecting plate 10. This enhances the stability of the entire auxiliary tool and prevents it from tipping over or shifting during operation due to an unstable center of gravity.

[0035] The above solution achieves unified application of construction and maintenance, significantly saving costs and shortening the construction period. By using auxiliary tools in the limited space of the cantilever structure, the difficulty of construction near operating lines is reduced, the efficiency of construction and maintenance is improved, the impact of eaves work on railway transport equipment is weakened, and the safe and stable operation of railway lines is ensured, providing a safer and higher-quality travel environment for passengers. It is worthy of continued promotion and application in the construction and renovation of concrete cantilever structures, especially concrete canopies.
