Description

Reinforced structure of reinforced concrete structure by replacing part of steel bars with section steel

The invention relates to a stiffening structure for assembling reinforced concrete structures by replacing part of steel bars with section steel.

According to the reinforced concrete structure of traditional buildings (referred to as RC structure), the construction steps are as follows: lofting, steel reinforcement, water and electricity piping, formwork assembly, concrete grouting, formwork removal, painting and decoration and other steps can be completed, while the traditional RC structure Reinforcing bars are mainly used as structural components. Please refer to Figures 1 and 1A. Reinforcing bar members 1 in traditional RC structures are divided into column bar bar members 10, beam bar bar members 11, plate bar bar members 12, and wall bar bar members 13. etc., wherein the column reinforcement member 10 is made up of the main column reinforcement bars 100 and the column stirrups 101, which are bound one by one with iron wires, and the beam reinforcement member 11 is made up of the main beam reinforcement bars 110 and the beam stirrups 111, which are bound one by one with iron wires. In this way, the slab reinforcement member 12 is made of the upper reinforcement 120 and the lower reinforcement 121 bound with iron wire one by one, and the wall reinforcement member 13 is made of the straight reinforcement 130 and the transverse reinforcement 131 tied with iron wire one by one, so the building The assembly of the reinforced member 1 is very time-consuming and labor-intensive, and after the reinforced member 1 is assembled, a formwork 14 is set up on the outside of the reinforced member 1 as a casting mold for pouring concrete, and then concrete is poured into the casting mold formed by the formwork 14. , so that the concrete wraps the reinforced member 1 to form the RC structure. After the concrete is solidified to a certain strength, the formwork 14 is removed, and then the concrete surface is painted and decorated, so that all the construction procedures can be completed.

The deficiencies of the conventional RC structure are as follows: 1. It is known that more than 90% of the whole process of RC structure needs to be assembled and manufactured on the construction site, the overall operation efficiency is poor, and the accuracy and quality control are also poor. 2. With the global warming, it is known that the construction of RC structures is often carried out in scorching high temperature and dirty environment, or cannot be constructed due to rainy days, which affects work efficiency and also causes young people to be reluctant to invest in the construction industry. one. 3. With the growth of the global economy, it is gradually difficult to introduce foreign labor, and the local skilled labor is getting older and older, resulting in a serious shortage of labor in the construction industry. 4. Due to the large slenderness ratio of the steel bar, and only the steel wire is used to bind the steel bar, the assembled steel bar frame is not stable. 5. In order to facilitate the construction of the RC structure, the main reinforcement of the column on each floor must be lapped or connected by a coupler; relatively, the main reinforcement of the beam is relatively less connected; therefore, the conventional RC structure has the "strong beam". The potential problem of "weak columns", which can be exemplified by the collapse of buildings caused by earthquakes almost as a result of column damage. 6. When assembling the steel bar components of the foundation column, due to the lack of accurate and stable placement points, it can only be positioned by the simple tripod support type of steel bar erection. In addition to the inability to accurately locate, it is also difficult to ensure its uprightness. 7. It is known that during the construction of RC structure, the steel bar assembly, water and electricity elimination piping and formwork assembly usually need to be constructed interactively, often resulting in mutual waiting. In addition to wasting the construction period, it is also known that the water and electricity consumption pipe is broken when assembling the template. . 8. Formwork assembly and reinforcement assembly often do not have accurate and consistent reference lines for the two, often resulting in insufficient protective layer on one side and too thick protective layer on the other side. 9. Due to the large amount of steel bars at the beam-column junction, it is not conducive to concrete pouring. In addition to the phenomenon of concrete honeycomb, it is also common to derive the bad behavior of adding water to grouting. 10. Most of the traditional RC structures are operated on the construction site, and the construction accuracy is poor. After the demoulding, a lot of painting, leveling and decoration operations are required, which not only takes labor and time, but also increases the construction cost.
