The utility model relates to the field of construction engineering structure technology and construction, in particular to a construction device for a reinforced concrete column without dismantling.

(2) Background technology

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 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.

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 It is possible to be exposed.

Groove: The setting of the through groove enables the connector on the outside of the cement fiber board to be automatically adjusted according to the width of the steel cage, so that the connector can better adapt to the size of the concrete column and achieve the purpose of recycling.

The top surface of the corner angle steel is provided with a piercing angle steel bolt hole, and the top surface of the connector is provided with a corresponding bolt hole. By fixing the bolt on the piercing angle steel bolt hole and the bolt hole, the corner angle steel and the connector The connection is fixed.

The inner corners of the two adjacent cement fiber boards are provided with corner connectors at intervals in the vertical direction, and the corner connectors are connected to the cement fiber boards by self-rivets, so that the cement fiber boards are fixed more firmly.

The utility model uses the cement fiber board which is light in weight, high in strength and can be manufactured on a large scale in the factory as a reinforced concrete column template, which saves the resources and time required for making the template, and prevents the size of the existing template from not conforming to a specific engineering framework. The use of cement fiberboard optimizes the cumbersome mode of fixing formwork in the past, and its appearance is beautiful. Sometimes the outer wall can be used directly without painting.

The utility model is simple in structure, flexible in application, reduces the amount of steel formwork or wooden formwork, saves steel and wood, and protects the environment. At the same time, the cement fiber board itself can replace part of the concrete thickness, reducing the amount of concrete, and the angle steel at the corner is removed. The utility model is convenient, can be flexibly adjusted according to the actual size, and can be recycled, which saves the construction cost and is suitable for wide popularization and application.
