Description

TECHNICAL FIELD

[0001] The present application relates to a support base device and method of use, in particular to a support base device and method of use for a construction cage. BACKGROUND

[0002] In various types of construction engineering construction, from high-rise residential, commercial complex to bridge, water conservancy and other infrastructure projects, the safe and efficient passage between different height work surfaces of construction personnel is the key link to ensure the smooth progress of construction. The stability and safety of the cage, as an important facility for personnel vertical passage, are directly related to the life safety of construction personnel and the construction progress. The construction cage is an important equipment in building construction, which is used to ensure the safety of construction personnel during high-altitude operation. It has good bearing capacity and stability, and can ensure the safe movement of workers between different heights. In order to install the construction cage in the construction foundation, the support base device for the construction cage is an important building construction component. In the existing support base device for the construction cage, most of them adopt concrete structure. Although it can meet the basic bearing demand in a certain period of time, with the rapid development of the construction industry and the continuous improvement of construction requirements, its technical shortcomings are increasingly prominent: 1. Serious waste of resources: the concrete base is a one-time use product, which is difficult to recycle after the project is completed. A large amount of concrete material is abandoned, which not only causes great waste of resources, but also increases the disposal cost of construction waste, which does not meet the current green building and sustainable development concept, 2. Long construction period: the concrete base needs a long curing time to reach the design strength after pouring, which cannot be used for subsequent construction operation during this period, seriously affecting the overall construction progress. In the project with tight schedule, the curing time of the concrete base becomes an important factor restricting the construction efficiency, which increases the time cost of the project, 3. High cost: the cost of the concrete base not only includes the purchase of raw materials and transportation fees, but also involves the cost of formwork making, pouring construction, maintenance and later removal and cleaning of multiple links. Since it cannot be used repeatedly, the base needs to be re-made for each project, further increasing the construction cost, 4. Poor adaptability: once the traditional concrete base is poured, its position and shape are difficult to change. In the case of complex construction site, such as site planning adjustment or construction condition change, the concrete base is difficult to adapt to the change, which brings many inconveniences to the construction, The present application effectively explores and researches the technical problems of installing and fixing the construction cage by using the technical features of the detachable and re-installable base assembly spread on the foundation of the installation site of the construction cage, which solves the technical problems of installing and fixing the construction cage by using the concrete structure. The statements herein only provide the background of the present application and do not necessarily constitute the prior art, based on the technical disclosure provided by the applicant on February 15, 2025, the technical problems solved in the process of work, the existing technical problems, technical features and technical effects in the background technology obtained through retrieval, and the application technical scheme of the present application is made.
