Concrete column pouring construction method based on telescopic string device

Abstract

The invention discloses a concrete column pouring construction method based on a telescopic tumbling barrel device. The telescopic tumbling barrel device comprises tumbling barrels, a positioning mechanism arranged at the tops of the tumbling barrels and used for positioning the tumbling barrels, and a control module arranged on the positioning mechanism and used for controlling the tumbling barrels to extend and retract. The concrete column casting construction method comprises the following steps that first, the telescopic tumbling barrel device is mounted; second, the tumbling barrels are wetted; third, concrete is poured; fourth, the telescopic tumbling barrel device is demounted; and fifth, later repouring is conducted. The concrete column pouring construction method is simple in step, construction is convenient and rapid, the tumbling barrels can be automatically controlled to extend and retract according to the real-time pouring height of the concrete, thus the free falling height of the concrete is flexibly controlled in the concrete pouring process, the phenomenon of concrete segregation is avoided effectively, meanwhile, the problems that at present, single sections of tumbling barrels need to be manually demounted one by one, the time and labor are consumed during operation, a machine is needed to be continuously matched with construction, and the concrete pouring efficiency is low are solved, practicability is high, and using and popularization are convenient.

Description

technical field [0001] The invention belongs to the technical field of concrete column pouring, and in particular relates to a concrete column pouring construction method based on a telescopic string device. Background technique [0002] With the rapid development of my country's economy, various large-span, large-section, and super-high structures have also emerged. Therefore, in the process of construction on construction sites, it is often necessary to pour some tall concrete columns. According to the requirements of national regulations , When the concrete pouring height exceeds 2m, it is necessary to use a stringer, a conduit or a chute for pouring to prevent the segregation of the concrete. Once the segregation phenomenon occurs, the workability of the concrete will be destroyed, resulting in quality problems such as honeycombs and holes in the concrete; , the strength of the concrete will also be greatly reduced, affecting the bearing capacity of the concrete structure,...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a concrete column pouring construction method based on a telescopic stringer device, which has simple steps, convenient and quick construction, and can automatically control the stringer according to the real-time pouring height of the concrete. The shrinkage of the tubes can meet the flexible control of the free fall height of the concrete during the concrete pouring process, effectively avoiding the segregation of the concrete, and at the same time overcoming the current need to manually remove the single-section string tubes one by one. The operation is time-consuming and laborious, and continuous mechanical cooperation is required for construction. , the problem of low concrete pouring efficiency, and strong practicability, easy to popularize and use
