Problems solved by technology

The higher the erection height, the more unstable the bracket, and there is a greater potential safety hazard; at the same time, the workload of sealing the opening of the I-beam and the opening of the wall part is too high, and the quality of the sealing cannot meet the requirements, and there are uneven outer walls, Late water leakage, etc.; handover of elevator shafts, etc.

Embodiment 1

[0058] The calculation is based on the construction building number of Baoshan Yongchang Jingyuan Construction Project (2 buildings on the 31st floor and 2 buildings on the 32nd floor). On average, 40 meters of steel pipes per layer of each elevator shaft are taken), during the entire main construction process, the maximum amount of steel pipes required for each elevator shaft is 378*40=15120 meters, the daily rent of steel pipes is 1.9 yuan / ton, and the steel pipes per meter If the weight is 3.84Kg, the daily rent of steel pipes = 15120 meters * 3.84Kg / m ÷ 1000 * 1.9 yuan / ton. Day = 110.3 yuan, the rent of fasteners (including cleaning fees) is 0.01 yuan / piece * day, and each layer of fasteners is 15, a total of 378 floors * 15 = 5670; the daily rent of fasteners = 5670 * 0.01 yuan / piece = 56.7 yuan / day; the daily rent of steel pipes and fasteners = 110.3 yuan + 56.7 yuan = 167 yuan. The construction period of the main body is calculated as 330 days. During the construc...

Abstract

The invention discloses a construction method for a tool-type all-steel construction platform of an elevator shaft. The construction method comprises (A) preparation for construction, (B) selection ofmaterials, (C) material unloading, (D) punching of screw eyes, (E) welding and splicing, (F) antirust paint brushing, (G) lifting, (H) fabrication of a hard protection steel platform, (I) use and (J)dismounting. The construction method disclosed by the invention is characterized in that the tool-type all-steel construction platform of the elevator shaft is used as near-edge anti-falling protection of the elevator shaft; processing is convenient; the platform can be dismounted and lifted layer by layer together with a main body structure; a tower crane is matched during lifting; lifting is convenient; construction is quick; the occupied area is small; safe operations are guaranteed; installation operations are convenient; practicability is high, etc. The method disclosed by the inventionhas the beneficial effects that a reinforcement process is simple; shaping quality is good; repeated use is feasible after one-time input; establishment of steel tube frames is not needed; only floorsealing is needed; rental for steel tubes can be reduced; economic benefits are significant; installation is convenient; dismounting is easy; and carrying and transportation are convenient.

Description

technical field [0001] The invention designs the field of building construction, and is specifically a construction method for an elevator shaft tool-type all-steel construction platform. Background technique [0002] In the construction of high-rise building structures, the formwork (wooden formwork, aluminum formwork) of the elevator shaft traditionally uses a floor-standing steel pipe fastener scaffolding platform (or I-beam suspension beam operating platform), which takes a long time to set up and requires a lot of manpower and material resources. . The higher the erection height, the more unstable the bracket, and there is a greater potential safety hazard; at the same time, the workload of sealing the opening of the I-beam and the opening of the wall part is too high, and the quality of the sealing cannot meet the requirements, and there are uneven outer walls, Late water leakage, etc.; the handover of the elevator shaft is lagging behind. [0003] Therefore, in orde...
