Description

Technical Field

[0001] The invention belongs to the technical field of construction engineering construction, and particularly relates to an adjustable stress anti-pull wall-riding type hanging basket redundancy protection system and a construction method thereof. Background Technique

[0002] The large-scale comprehensive buildings in the new business form take "tripod" as the inspiration source, interpret the standing intention with the tripod base, the tripod body and the tripod ears, and are topologically complementary, standing in the park. The design of the roof tripod ears fully considers green energy conservation and the pursuit of visual effects. The design introduces a double-layer roof trellis beam to achieve a "dou" shape. Through the inclined arrangement of the double-layer roof trellis beam and the rods at a certain angle in combination with the building roof sunshade, the iconic fifth facade of the "tripod" tower is created.

[0003] For the iconic vertical four facades of the "tripod" tower in the city, the peripheral decoration structures are mostly made of metal materials, stone materials and energy-saving glass, forming extremely complex glass curtain wall systems, shaped metal plate curtain wall systems and dry-hung stone curtain wall systems. The rhythmic combination presents a highly modern curtain wall system. The construction of the vertical high-rise curtain wall depends on various high-altitude manned working tools. The hanging basket is a commonly used construction tool for high-altitude operations in building engineering, and is used for curtain wall installation and exterior wall cleaning. The cantilever mechanism is erected on the building or structure, and the suspension platform is driven by the lifting mechanism, and the construction facility that runs up and down along the facade of the building or structure through the steel wire rope is also a working platform set for the operators. The hanging basket is a new type of high-altitude operation equipment that can replace the traditional scaffolding, can reduce the labor intensity, improve the work efficiency, and can be reused. The use of building hanging baskets has gradually become a trend and has been widely recognized in high-altitude operations such as the exterior wall construction, curtain wall installation, thermal insulation construction and maintenance and cleaning of exterior walls of high-rise and multi-storey buildings. At the same time, it can be used for the operations of large tanks, bridges and dams and other projects.

[0004] Due to various reasons, the falling accidents of high-altitude operation hanging baskets in building construction occur from time to time. According to the safety statistics, the percentage of the total number of safety accidents occurring in high-altitude operation equipment is increasing. The existing national standards have stipulated the indexes of each component of the working hanging basket, but in actual application, the installation methods, fixing schemes, load sizes and environmental disturbances will be different, and it is still necessary to carry out calculation and analysis in combination with the specific environmental conditions to ensure safety.

[0030] Compared with the prior art, the present invention has the following characteristics and beneficial effects.

[0031] 1. The mounting frame in the redundant protection system of the adjustable stress reverse tension wall-riding hanging basket of the present invention is welded with a long angle L70*90*8mm and a steel plate (100*70*8mm). The mounting frame is connected to the upper beam to form the main force-bearing structure and anti-overturning device of the hanging basket suspension beam. The vertical supports of the mounting frame are respectively arranged on both sides of the upper beam, and the vertical supports and the lower tension bolts and the upper tension bolts form a hoop together. The hoop is arranged on the upper beam, which increases the stability of the mounting frame. The setting of this mounting frame not only prevents the hanging basket from falling and overturning, but also increases the contact area with the upper beam to prevent damage to the beam.

[0032] 2. The arrangement of the two anti-pulling steel wires (main load-bearing steel wire and auxiliary load-bearing steel wire) of the present invention forms a double protection. The lower layer beam is anti-pulled and clamped by the two anti-pulling steel wires. The main load-bearing steel wire is the main rope and bears the main load, while the auxiliary load-bearing steel wire is the auxiliary rope and does not bear force under normal conditions. When the main load-bearing steel wire is overloaded and may be damaged, the length of the auxiliary load-bearing steel wire can be adjusted, thereby adjusting the stress state of the auxiliary rope, and further reducing the tensile stress borne by the main load-bearing steel wire, thus greatly increasing the safety factor. At the same time, in the present invention, both the main load-bearing steel wire and the auxiliary load-bearing steel wire use M12 stainless steel locking devices to control the load. The connection between the main load-bearing steel wire, the auxiliary load-bearing steel wire and the end pulling point of the suspension beam is carried out by the first inclined ear plate. The stress of the steel wire is monitored by a dynamometer. A thimble is installed at the connection part of the main load-bearing steel wire, the auxiliary load-bearing steel wire and the steel wire, increasing the stress area of the steel wire, preventing the steel wire of the clamping beam from undergoing plastic deformation due to point stress and reducing its own strength, increasing the service safety factor and prolonging the service life of the steel wire. In addition, the present application uses a locking device to connect the steel wire, which is not only convenient for operation and installation, but also easy to control the stress of the steel wire, so as to facilitate the response to the stress conditions of the main load-bearing steel wire and the auxiliary load-bearing steel wire.

[0033] 3. The present invention fixedly installs a mounting frame on the upper layer beam to support the suspension frame, providing a stable connection foundation for the suspension beam. At the same time, the inventor extends the inner end of the sling to the rear mounting frame, winds it around the vertical support, and uses a fourth stainless steel locking device to fix the sling. The inventor locates the fourth stainless steel locking device of the sling between the two vertical supports, making the rear vertical support bear force, increasing the safety of the force-bearing position, facilitating construction at the same time, and ensuring the safety of the installation construction personnel themselves. In addition, the inventor puts on a leather sleeve on the upper part of the sling for protection, avoiding direct friction between the sling and the vertical support and causing damage.

[0034] 4. The adjustable stress anti-pulling over-the-wall hanging basket redundancy protection system of the present invention is applicable to the anti-pulling over-the-wall hanging basket, especially applicable to installing the anti-pulling over-the-wall hanging basket on the double-layer flower rack beam on the roof. By using different detailed protection mechanisms, a safety redundancy defense line is established to form a multiple life protection safety system, and the realization of "safety redundancy" is not redundant.

[0035] 5. Aiming at the weak links of the conventional anti-pulling over-the-wall hanging basket, based on the principle of redundant safety governance, the present invention conducts targeted research on the redundant protection system of the anti-pulling over-the-wall hanging basket for high-altitude operations on the roof, establishes a safety redundancy defense line, controls potential accident hazards, and realizes safe production. It not only ensures "just enough" safety, but also provides sufficient insurance for safety to make it sufficiently safe. BRIEF DESCRIPTION OF THE DRAWINGS
