Embodiment Construction
[0014] The present invention will be described in detail below in conjunction with specific embodiments.
[0015] Such as figure 1 Shown building peripheral scaffolding of the present invention removes lifting method, comprises the following steps:
[0016] Step 1. Select a vertex at the bottom of the multi-storey building as the origin, take the two sides perpendicular to each other as the X-axis and the Y-axis respectively, and use the vertical direction as the Z-axis to establish a spatial Cartesian coordinate system.
[0017] Step 2. Place the steel pipes of each layer of scaffolding on the periphery of the building after the demolition into several groups of steel pipes, and then group and number each group of steel pipes, and count the coordinate positions of each group of steel pipes in the space Cartesian coordinate system. The number of steel pipes and the number of floors where the crane is located will be entered into the local access database.
[0018] Step 3. Ut...

The invention discloses a removal and lifting method for scaffolds on the periphery of a building. The removal and lifting method for the scaffolds on the periphery of the building comprises the following steps that one vertex at the bottom layer of a multi-storey building is chosen as the original point, two sides, perpendicular to each other, of the vertex are taken as X-axis and Y-axis separately, and a space rectangular coordinate system with the vertical direction as Z-axis is established; each layer of scaffold steel pipes after removal are separately and centrally placed into a plurality of groups on the periphery of the corresponding layer of the building, then each group of steel pipes is numbered by grouping, and the coordinate position of each group of steel pipes in the space rectangular coordinate system, the number of the steel pipes in each group and the number of the layer at which a crane is located are counted; the best placement point of each group of steel pipes after each layer of scaffold is removed is calculated and selected by Visual Basic; lifting datum lines are determined; and the crane is moved to the intersection point of the final lifting datum line and the layer at which the crane is located for lifting. According to the removal and lifting method, the efficiency is improved greatly, and construction personnel can quickly transport and lift removed scaffold equipment conveniently.
Description
technical field [0001] The invention relates to a dismantling and lifting method, in particular to a dismantling and lifting method for building peripheral scaffolding. Background technique [0002] Scaffolding is a support system erected at the construction site for workers' operation, safety protection, floor horizontal transportation and formwork support. Because of its advantages of flexible erection, strong versatility, and economic adaptability, it is widely used in the construction process of construction projects. At present, most domestic construction companies use manual unloading in the construction of scaffolding dismantling and unloading. The main problems are high safety risks, high labor costs, difficult construction and low efficiency. Some enterprises use cranes to unload, but due to scattered tasks, the cost is high. The removal and lifting method of scaffolding outside the building is a good solution to this engineering problem. This method is mainly to g...
