Description

A safety protection platform for steel platform inclined wall construction and its use method

Technical field

The invention relates to the field of building construction, and in particular to a safety protection platform for steel platform inclined wall construction and a method of using it.

Background technique

With the progress of human society, cities have also ushered in a stage of rapid development, and land has increasingly become a scarce resource. The contradiction between people's increasing requirements for activity space and limited land resources has become increasingly fierce. , while high-rise buildings (especially super-high-rise buildings) seek upward space, which alleviates this increasingly intensifying contradiction to a certain extent. In the core tube construction of high-rise and super-high-rise buildings, steel platforms are used due to their high construction efficiency and safety. The advantages of high coefficient, good construction quality, high degree of automation, small impact on the environment, and low comprehensive construction cost are increasingly valued by people and are used in more and more engineering projects. At present, most super high-rise buildings need to install core tubes to improve the lateral force resistance of the overall tower. As the number of structural floors continues to increase, the stress form of super high-rise buildings will gradually transform from bending-shear type to bending type. Compared with the bottom floor, the bending moment is relatively small, and the corresponding tension and pressure on the core wall will be reduced.

In order to adapt to the stress mode of super high-rise core tubes, people often use methods to reduce the number of core tubes and reduce the core wall thickness to reduce the plane area and component cross-section of the core tube. With the continuous accumulation of experience in the construction of super high-rise core tubes, people have found that the core tube adopts the inclined wall taper mode, which can not only adapt to the stress mode of the super high-rise core tube, but also reduce the plane area of the core tube and achieve structural and load optimization. Adaptable and save materials. However, due to the contraction of the inclined wall of the core tube, the inner cylinder frame of the steel platform will collide with the inclined wall during the lifting process of the steel platform, hindering the normal lifting of the core tube. Therefore, when the core tube encounters the inclined wall and points , people often use the method of dismantling the steel platform layer by layer to solve this problem. Although this solves the problem of the super-high-rise core tube inclined wall retracting the segmented steel platform for climbing, the steel platform is already tens of meters or even tens of meters above the ground. Cutting a steel platform at an altitude of hundreds of meters is extremely dangerous. If safety measures are not taken, it may threaten the life, health and safety of operators and other personnel. In serious cases, it may cause mass deaths. serious safety incidents.

In order to ensure safe construction of the steel platform under the condition of using inclined walls, the following two safety measures are currently commonly used: 1) Install a safety protection net under the steel platform. Although this method is simple to operate and low in cost, due to the protection The net cannot block smaller falling objects, and there is still the risk of falling objects from high altitude. In addition, due to the limitations of the material of the safety net itself and the impact of the construction environment, the safety net is often easily damaged and must be replaced regularly, but under the steel platform There is no suitable operating space, and it is a high-altitude operation. Safety accidents such as falling from high altitude may occur, threatening the life and health of operators; 2) Install a fixed platform under the steel platform, but in order to ensure that the steel platform can smoothly pass through the inclined wall, The fixed platform is often made too small. When the steel platform is about to pass through the lower end of the inclined wall, the distance between the edge of the fixed platform and the concrete wall is large, making it impossible to seal the bottom of the steel platform well. When cutting at high altitude When building a steel platform, there is still the risk of parts falling. Falling components may endanger the lives of construction workers below or cause damage to the substructure.

To sum up, when faced with the construction of inclined walls, the two current steel platform safety protection measures mentioned above are increasingly unable to meet people's requirements for low risk, high efficiency, high safety and simplicity in the construction of super high-rise buildings. requirements, in order to improve the work efficiency and installation quality of super high-rise building core tube construction using inclined walls, and reduce safety risks and labor intensity of workers, a safety protection platform for steel platform inclined wall construction and its use were developed The method has become an urgent technical problem that those skilled in the art need to solve.

Contents of the invention

The purpose of the present invention is to provide a safety protection platform for steel platform inclined wall construction to solve the problems of existing steel platform safety protection measures such as high safety risks, complicated operations, and low efficiency when facing inclined wall construction. . Install a safety protection platform below the steel platform. The safety protection platform can be adjusted according to the condition of the steel platform. On the one hand, when the steel platform is working stationary, due to a certain gap between the steel platform and the concrete wall, the construction workers above are tying steel bars, During the process of installing formwork, pouring concrete, etc., especially when the steel platform passes through the inclined wall and is sectioned, it is necessary to cut part of the structure of the steel platform. It is inevitable that some parts and cutting objects will fall from above, endangering the safety of the construction workers below. life safety or damage to the underlying structure. At this time, the safety protection platform and the core wall form a relatively closed space to prevent objects above from falling during construction, ensuring the life safety of the construction workers below or the quality safety of the substructure; on the other hand, due to measurement and construction Errors in the process, especially when the core tube encounters inclined walls and are segmented, are limited by the construction environment and measurement methods. It is even more difficult to ensure the accuracy of steel bar binding and concrete pouring, resulting in poor wall surface of the final poured concrete wall. A larger error will occur, and sometimes there may be some protrusions. When the steel platform climbs upward, the protective platform that is too tightly closed will inevitably get stuck, affecting the normal climbing of the steel platform.

Step 7: After operating the steel platform to climb to a predetermined height, lock the position of the steel platform, operate the lifting system, and slowly lower the movable flip mechanism until it leans against the concrete wall;

Step 8: Repeat steps 5-7 until the steel platform climbs to the next section of vertical wall construction;

Step 9: Repeat steps 2-3 until the core tube construction is completed.
