Description

Technical Field

[0001] The utility model relates to the technical field of construction of building facades, in particular to a safe operation conversion frame for repairing exterior walls. Background Art

[0002] At present, urban construction has gradually entered the era of inventory. The residential and commercial areas in the main urban area are close to and, after decades of use, there is a great need for renewal and renovation, especially the facade. On the one hand, it represents the image of the city. On the other hand, due to the backward waterproofing technology of old buildings, the hidden dangers of facade leakage have increased and urgently need to be repaired. Therefore, more and more cities or blocks are joining the ranks of facade renewal and renovation.

[0003] Facade work on new buildings often utilizes double-row floor-mounted scaffolding, cantilevered scaffolding, or hanging baskets. However, the renovation of facades on older urban buildings differs significantly from new construction. Rooftops are often cluttered with air conditioners and other equipment, occupying significant space and making it impossible to set up hanging baskets for overhead work. Therefore, external scaffolding is often used. However, many buildings, such as street-side shops, office buildings, and residential buildings, often have gatehouses and awnings. These established obstacles make it impossible to properly erect scaffolding along the facade from the ground. These gatehouses and awnings are often insufficiently rigid to serve as a stable foundation to support the weight of the scaffolding. Furthermore, removing these obstacles and then erecting scaffolding would be prohibitively expensive.

[0004] Summarizing the existing facade renovation safety construction technology, there are the following problems:

[0005] 1. The roof space of some buildings is limited and it is not possible to install operating facilities such as hanging baskets;

[0006] 2. In order to prevent damage to the interior decoration layer of existing buildings, it is not advisable to install through-wall screws or cantilever scaffolding;

[0007] 3. If there are no cantilevered components on the facade, the external frame can be erected normally; if the ground scaffolding encounters obstacles, it will be erected directly upwards, which will cause it to be too far away from the exterior wall, affecting operation and safety;

[0008] 4. If ordinary steel pipes are used for horizontal reinforcement, the rigidity is often insufficient, which may easily cause safety risks. Utility Model Content

[0009] In order to solve the above-mentioned defects, the utility model provides a safe operation conversion frame for exterior wall repair.

The reverse pull frame body is arranged on the ground and connected to the operating frame body after bypassing obstacles. A reverse pull structure is arranged on the reverse pull frame body to keep the operating frame body and the reverse pull frame body balanced.

[0011] The safety operation conversion frame for exterior wall repair and the anti-pull frame are assembled, which are spliced ​​with steel sections according to the volume of the obstacle and can bypass the obstacle.

[0012] The above-mentioned safe operation conversion frame for exterior wall repair and the reverse tension frame are fixed to the ground by expansion bolts.

When the external frame is erected later, the external frame uprights are placed on the short steel pipes to prevent the external frame from moving. The end steel plates are welded to both ends of the steel section, and circular high-strength bolt holes are drilled.

[0015] The adjusting beam (2) is a connecting member, and the length of its steel section is related to the width of the existing building cantilever member; when reinforcement is required, a lifting lug is welded on the upper part of one end of the steel section, and the lifting lug is made of thick steel plate; end steel plates are welded to both ends of the steel section, and bolt holes are drilled; stiffening plates are set corresponding to the column positions, and elliptical bolt holes are drilled on the upper and lower flange plates;

[0017] The safety operation conversion frame for exterior wall repair has an adjustment beam (2) that is a universal component with lengths of 1.0m, 1.5m, 2.0m, and 3.0m.

[0018] The utility model proposes a detachable and recyclable steel frame as a force conversion body, which provides a stable base for the upper frame, so that the facade renovation work can be carried out safely and reliably; the main components can be formed into customized components, which is convenient for engineering processing and manufacturing; the component materials can be recycled and reused; the conversion frame can be combined with the actual situation on site, and the size can be freely selected and adjusted.
