Problems solved by technology
[0003] The key technical problem to be solved by the present invention is to creatively provide a technologically advanced, economically scientific, safe and reliable method for checking the bearing capacity and construction of the elevator installed on the roof of the underground garage, omitting the need for the elevator to go through the hole and unloading on the roof of the underground garage. Install the elevator directly on the roof of the underground garage without the tedious construction process such as support

Embodiment Construction
[0099] Attached below Figure 1~4 The present invention is further described:
[0100] Such as figure 1 , 2 , 3, shown in 4, on the underground garage roof of the present invention, lift bearing capacity check and construction method are installed, it is characterized in that take the following steps:
[0101] 1. Determine the model and installation height of the lift 15
[0102] Determine the type and installation height of the elevator 15 according to the vertical transportation workload of the construction project and the height of the building;
[0103] 2. Lift foundation 3 drawing positioning
[0104] On the roof structure diagram of the underground garage, select the position of the window opening 2 where the inner edge of the elevator foundation 3 is 0.6m to 1.5m away from the outer edge of the main building exterior wall 1 to draw the floor plan of the elevator foundation 3;
[0105] 3. Calculation of Design Value of Uniformly Distributed Live Load of Lift Foundat...

The invention belongs to the field of building structure design and and construction cross technologies and particular relates to a bearing capacity checking calculation and construction method for mounting a lift on an underground garage roof cover. The method is characterized by comprising the following steps: one, determination of the lift type and the installation height; two, positioning of the lift base drawing; three, lift base uniform distribution live load calculation; four, underground garage roof cover bearing capacity checking calculation; five, lift base real object positioning; six, lift base construction; seven, lift installation. Under the working condition that the earth quack action is not considered, the underground garage roof cover bearing capacity checking calculationis performed with lift equivalent uniformly distributed load. Compared with the traditional construction method, the lift vertical conveying efficiency is improved by 1 / 3, the tedious construction processes of hole opening, hole filling and the like when the lift passes through the underground garage roof cover are omitted, construction material secondary transportation is avoided, the construction period is shortened greatly, a lot of the construction comprehensive cost is saved, and the method meets the green construction requirements of high efficiency, energy saving and environment protection.
Description
technical field [0001] The invention relates to a bearing capacity check calculation and construction method of an elevator installed on the roof of an underground garage, and belongs to the interdisciplinary technical field of architectural structure design and construction. It is suitable for the design and construction of elevators installed on underground garage roofs such as well-shaped beams, primary and secondary beam roofs, dense rib membrane shells, dense rib laminated boxes, dense rib mold boxes and other new hollow roofs. Background technique [0002] At present, underground garages are designed in the building complex area. During the main construction stage of the main building, elevators are usually used for vertical transportation of materials and construction workers. , design units, construction units, etc. expressly prohibit the installation of lifts on the roof of underground garages. Therefore, it is only possible to cut off the holes reserved for the el...
