Detailed Description
The embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the embodiments are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are given, but the scope of the present invention is not limited to the following embodiments.
A large-tonnage bearing work platform for elevator shaft department is built in room, constitute by supporting part and bearing part. The supporting part comprises supporting units which are longitudinally superposed, the number of the supporting units is related to the number of the structural plates, each supporting unit comprises an upright post positioned between adjacent structural layers, longitudinal beams which are flush with the corresponding structural layers are arranged on the top surfaces of the group of upright posts, and connecting beams are arranged between the longitudinal beams; the bearing part is located top layer supporting unit's top surface, and it includes a plurality of steel pipe bank that set up along longeron extending direction tiling, and each steel pipe bank all includes many and longeron looks vertically steel pipe, and the steel pipe in each steel pipe bank tiles in proper order and welds continuously.
Specifically, the present invention will be described with reference to an elevator shaft operation platform having a three-deck structure as described below. As shown in fig. 1-3, I25b I-beam is used as the upright 1, I30b I-beam is used as the longitudinal beam 2, and I12I-beam is used as the connecting beam 3. Firstly, constructing a first-layer supporting unit, namely installing upright posts 1 on the bottom surface of a foundation pit according to the longitudinal spacing of 2.8m and the transverse spacing of 2.9m, wherein the top surface of each upright post 1 is flush with a structural slab; then, welding two rows of longitudinal beams 2 at the top of the upright post 1, wherein the longitudinal beam 2 in one row is arranged close to the north side structural plate M; next, connecting beams 3 are welded between adjacent longitudinal beams 2 and between another row of longitudinal beams 2 and the south side structural panel N, and the end portions of the connecting beams 3 are arranged corresponding to the columns 1, so that the transverse distance between the connecting beams 3 is also 2.9 m; and finally, placing 4 rows of prefabricated steel pipe tubes on the top surface of the supporting unit by using a forklift as a bearing surface. Each steel pipe tube bank 4 is formed by arranging 6 steel pipes with the length of 9m, the diameter of 120mm and the wall thickness of 8mm side by side and welding the steel pipes in sequence, each steel pipe is perpendicular to the longitudinal beam 2 when the steel pipe tube banks 4 are paved on the top surface of the supporting unit, and the end parts of the steel pipes are covered on the structural slab. When the bearing load is large, one or more layers of steel pipe rows 4 can be paved for reinforcement. And after the reinforced concrete support above the first layer of support units is completely dismantled, removing the steel pipe rows 4 on the top surface of the first layer of support units, continuously welding the support units on the second layer of support units on the steel pipe rows, paving the steel pipe rows for dismantling the reinforced concrete support, and after the dismantling, lapping the support units on the third layer of support units and the steel pipe rows according to the steps. The above-mentioned layers of support units differ only in height.
