Formwork removal-free reinforced concrete column construction device

Abstract

The invention relates to the field of construction engineering structural technologies and construction, in particular to a removal-free reinforced concrete column construction device. The formwork removal-free reinforced concrete column construction device comprises a column steel reinforcement cage. The formwork removal-free reinforced concrete column construction device is characterized in that the outer side of the steel reinforcement cage is provided with cement fiber plates which are connected with the sealing steel reinforcement cage surface, the inner surface of each cement fiber plate is provided with rectangular bulge blocks which are distributed in a quincuncial mode, outer side connecting angels of every two connected cement fiber plates are provided with angle part angle iron in the vertical direction at intervals, and connecting parts are arranged between the every two adjacent angle part angle iron in the same horizontal plane. The formwork removal-free reinforced concrete column construction device is simple in structure and flexible in application, the using amount of steel formworks or wooden formworks is reduced, steel materials and wooden materials are reduced, and the environment is protected.

Description

(1) Technical field [0001] The invention relates to the field of construction engineering structure technology and construction, in particular to a construction device for a reinforced concrete column without demolition. (2) Background technology [0002] At present, reinforced concrete columns mostly use detachable steel plates or planks as templates for concrete pouring. Limited by the number of formwork on site, especially for large-scale projects, when there are many columns, more formwork is required, which increases the amount of steel and wood used, thereby increasing the cost and destroying the ecological environment; when the formwork is removed, due to the cement It is difficult to remove the formwork, and sometimes even when the concrete has not fully hardened to remove the formwork, it is possible to pull out part of the concrete; in addition, such as the frame column of 500mm*500mm, the current detachable formwork is used for construction , it is necessary to m...

Problems solved by technology

Limited by the number of formwork on site, especially for large-scale projects, when there are many columns, more formwork is required, which increases the amount of steel and wood used, thereby increasing the cost and destroying the ecological environment; when the formwork is removed, due to the cement It is difficult to remove the formwork, and sometimes even when the concrete has not fully hardened to remove the formwork, it is possible to pull out part of the concrete; in addition, such as the frame column of 500mm*500mm, the current detachable formwork is used for construction , it is necessary to make a formwork of the corresponding size. When the other columns are larger or smaller, they need to be reassembled or customized, and the availability of the formwork is low.

[0003] At present, in the method of directly adding formwork outside the steel cage, when pouring concrete, due to the agitation of the vibrating rod, it is very likely that the steel cage will be inclined, so that the thickness of the concrete cover will be uneven, and even when the inclination angle is large, some steel bars may be exposed
