Description

Technical Field

[0001] The invention belongs to the technical field of equipment in the construction industry, and in particular relates to a modular pneumatic escape device and an installation method thereof. Background Art

[0002] With the acceleration of urbanization, the number of high-rise buildings is increasing, and the safety issues in their construction phase are becoming increasingly prominent. However, most of the existing related escape devices are used in already built buildings, such as slide escape devices, etc. These devices are often designed for already built buildings, so they have the disadvantages of occupying large structural space, high cost and slow escape rate. In addition, these devices cannot be used in the construction phase for various reasons.

[0003] Specifically, the existing escape devices have the following deficiencies, which limit their application in the construction stage:

[0004] 1. Complex installation forms, technical specifications and applicability limitations: Existing escape devices often require fixed installation points or specific building structures to support them, while temporary structures or incomplete building environments during the construction phase are difficult to meet these technical specification requirements; in addition, these escape devices often lack design considerations for specific risks during the construction phase.

[0005] 2. It occupies a large structural space, is expensive, and has economic cost issues: Existing escape devices often require a large amount of structural space, and the space during the construction phase may need to be used for other temporary facilities or the storage of construction materials, which limits the installation of escape devices; in addition, the cost of escape devices is usually high, and construction units may not be able to bear these costs with limited budgets, especially during the construction phase, when resources and funds are more inclined to be invested in the construction of the main structure of the building.

[0006] 3. Complex operation, difficult maintenance, and safety and efficiency issues: Existing escape devices are complex to operate and require professional training, but construction workers may lack the corresponding training and experience, resulting in the inability to effectively use these devices in emergency situations; at the same time, complex escape devices require regular maintenance and servicing, but the construction phase may lack appropriate maintenance conditions and professionals, resulting in the device being unusable or reduced reliability; in addition, the dynamic environment of the construction phase increases the complexity and risk of using escape devices, especially during the construction phase of high-rise buildings, and the shortcomings of existing escape devices in terms of escape efficiency and safety are more prominent.

[0007] 4. Psychological and behavioral characteristics: In emergency situations of fire hazards, especially when the complexity of fire escape and evacuation in high-rise buildings increases, in temporary structures or incomplete building environments during the construction phase, the psychological and behavioral characteristics of construction workers may lead to the inability to effectively use fire rescue escape devices, such as fire rescue air cushions and aerial platform vehicles. In addition, the single rescue carrying capacity of these escape devices is also limited.

[0008] Therefore, in order to solve the problem of high-rise workers having difficulty escaping when a dangerous situation occurs during the construction phase, it is urgent to develop and design a modular pneumatic escape device and its installation method that are specifically suitable for the construction phase. The device can increase in height layer by layer as the building construction phase progresses, and can quickly and safely help high-rise workers escape from the scene, so as to meet the safety needs of the construction phase and improve the safety of construction workers.
