Description

Prefabricated composite reinforcement cage components and structures

technical field

The utility model belongs to the field of construction engineering and relates to a prefabricated combined reinforcement cage component and a structure.

Background technique

Reinforced concrete structures are widely used due to their advantages of integrity, durability, fire resistance and seismic performance.

Both methods involve the configuration of steel reinforcement inside the structure or component, and the existing reinforcement technology is mainly divided into two types:

One is that after the formwork is erected on site, the workers use this as a working platform to use full manual reinforcement. The safety risk of workers working at heights is high, the efficiency of manual operation is low and the accuracy is not easy to control, and the deviation of the reinforcement size is large. The formed reinforced concrete structure often has reinforcement bars. Quality defects such as exposed or uneven thickness of the concrete cover, and even problems such as missing and wrong reinforcements during the artificial reinforcement process, lead to a reduction or loss of the bearing capacity of the final reinforced concrete structure formed by pouring.

The other is the construction site or factory prefabricated reinforced concrete beams, columns, slabs and other components, which are transported to the site and placed in place to manually reinforce the joints. In order to meet the connection strength requirements of precast concrete components, the reinforcement of the connection nodes is complex and dense, the manual work space is very cramped, the construction is difficult, and the quality and strength of the steel connection are difficult to guarantee, which in turn affects the overall strength and stability of the reinforced concrete structure.

Existing PC components (full prefabricated reinforced concrete components) are heavy, difficult to transfer, hoist, and locate, and temporary auxiliary support facilities need to be built on site; during the assembly process, the vertical nodes need to be connected by grouting anchors, which requires high technical requirements and requires grouting construction techniques. and quality control measures are complicated; horizontal joints need to be connected by formwork support cast-in-place, embedded steel plate welding, high-strength bolt connection, etc. The process is complicated, the cost is high, and the reliability is poor. It can only be used after expert demonstration or identification organized by relevant departments.

Certainly, in the case that such adjacent members are provided with lugs, another construction scheme is possible: the steel bar truss 7 is no longer provided with pre-assembled movable steel bars 12, but the horizontal bars that affect plate assembly It is preset on the side of the pick ear (that is, it is located in the adjacent member, but not in the pick ear). After the floor reinforcement cage is in place, move the horizontal reinforcement to the pick ear and place it in place with the steel truss 7 connections as one.

The foregoing embodiments are only preferred implementations of the present utility model. It should be pointed out that for those of ordinary skill in the art, several improvements and equivalent replacements can be made without departing from the principle of the present utility model. The technical solutions after the improvement and equivalent replacement of the claims of the utility model all fall into the protection scope of the utility model.
