Large-size steel pipe column concrete construction device and construction method

Abstract

The invention discloses a large-size steel pipe column concrete construction device, comprising a scaffold, a steel pipe column and a concrete pump car, wherein the scaffold is arranged outside the steel pipe column; the concrete pump car is arranged on one side of the scaffold; a floating pressing plate is arranged in the steel pipe column; a floating pressing plate safe edge is fixed on the circumference edge of the floating pressing plate; a platform, near the top end, of the scaffold is provided with an inserted vibrating pump which is connected with a vibrating pump rod; the front end of the vibrating pump rod penetrates through the floating pressing plate and is fixed with a vibrating pump head; and a lifting lug is arranged in the central position of the floating pressing plate and is connected to the top end of the scaffold through a hauling cable. The construction device has the advantages that the manufacturing is simple, the mounting is convenient, the large-size steel pipe column concrete pouring, vibrating and lifting can be carried out and completed synchronously; potential safety hazards such as cavities, concrete vibrating lack and no slurry existing when concrete pouring is carried out can be avoided, the construction quality can be ensured, the investment cost is low, and the engineering efficiency is improved.

Description

technical field [0001] The present invention relates to a civil construction device and method, in particular to a large-scale steel pipe column pouring, vibration, and lifting concrete construction device and construction method. Background technique [0002] In the large-scale construction of the country, large steel pipe columns are indispensable as pillars. However, when the concrete core of the steel pipe column is poured, the concrete falls naturally through the concrete pump truck, so the mud splashes and the stones in the concrete sink. There is mud on the top and stones on the bottom, resulting in uneven proportions of the injected concrete components, and the quality cannot be guaranteed. In the existing construction method, when the concrete is poured to a certain height, the vibration effect of the plug-in vibrating pump used is not good, and the concrete cannot be vibrated comprehensively and evenly. , affecting the construction quality, the poured concrete str...
