Description

Technical Field

[0001] The utility model relates to a reinforced concrete structural column connection structure. Background Art

[0002] In construction projects, when the length of the infill wall exceeds the requirements of relevant specifications, it is usually necessary to set reinforced concrete structural columns at appropriate locations of the infill wall to enhance the stability and seismic resistance of the overall structure.

[0003] The current common practice is to cast the structural columns after the main structure is cast. Where the top of the structural column contacts the bottom of the beam or slab, a 10mm thick polystyrene rigid foam board is usually used to isolate it from participating in the overall load-bearing of the main structure. However, this method has some objective disadvantages:

[0004] Additional construction steps: Since the concrete needs to be poured after the main structure is poured before the structural columns can be poured, an additional step needs to be added during the construction process, which invisibly extends the construction period.

[0005] Surface sealing is complicated: after using polystyrene rigid foam plastic board to seal the contact position between the top of the structural column and the beam and the bottom of the slab, it is still necessary to manually use mortar to seal the surface, which also increases the construction process and construction difficulty.

[0006] These shortcomings not only complicate the construction process, but also increase labor costs and construction period. Therefore, how to simplify the construction process of structural columns, reduce the number of steps, and improve construction efficiency is an urgent problem to be solved in the current technical field. Utility Model Content

[0007] The purpose of the utility model is to provide a reinforced concrete structural column connection structure which reduces the number of working steps and improves the construction efficiency.

[0008] The purpose of this utility model is achieved in this way:

[0009] A reinforced concrete structural column connection structure, comprising column longitudinal bars, column bottom longitudinal bar dowels, column stirrups, column top structural formwork, structural column formwork, and column bottom structural formwork. After the column bottom longitudinal bar dowels and the steel bars of the column bottom structural formwork are tied together, concrete is poured into the column bottom structural formwork. After the concrete in the column bottom structural formwork reaches a certain strength, the column bottom structural formwork is removed to form the column bottom structure.

[0010] The column bottom structure is provided with a seam plate;

[0011] The column stirrups are used to overlap and tie the column longitudinal reinforcement and the column bottom longitudinal reinforcement.

[0012] After the longitudinal reinforcement dowels at the bottom of the column and the steel bars of the structural formwork at the top of the column are tied, concrete is poured into the structural column formwork and the structural formwork at the bottom of the column and vibrated to make it dense. After the concrete of the structural column formwork reaches the required strength, the structural column formwork is removed to form the main body of the structural column. After the concrete of the structural formwork at the top of the column reaches the required strength, the structural formwork at the top of the column is removed to form the column top structure.

[0013] Reduce construction processes: By setting a joint plate at the bottom of the structural column and the contact surface with the beam and slab, the structural column and the main structure can be cast as a whole at one time. There is no need to cast the structural column separately after the main structure is completed, which saves a construction process and improves construction efficiency.

[0014] Avoid structural columns from participating in the overall stress of the main structure: The use of seam plates effectively isolates the structural columns from the main structure, preventing the structural columns from bearing vertical loads, thereby achieving the separation of stress between the structural columns and the main structure and ensuring the safety and stability of the structure.

[0015] Simplify subsequent processing: Since the joint board naturally forms a concrete surface layer after concrete pouring, there is no need to manually use mortar to seal the surface, which further reduces the construction steps and manpower input and simplifies the construction process.

[0016] Save materials and costs: This patented structural column method only reserves column longitudinal reinforcement dowels at the bottom. Compared with the traditional method, it reduces the binding process of the top longitudinal reinforcement and dowels, saves the amount of steel bars, shortens the construction period, and thus reduces material costs and labor costs.

[0017] Improve construction quality: One-time integral casting avoids quality problems that may be caused by multiple constructions, and ensures a tighter and firmer connection between the structural columns and the main structure.

[0018] The purpose of the utility model can also be solved by the following technical measures:

[0019] Furthermore, the column bottom structure is a column bottom beam or plate.

[0020] Furthermore, the column top structure is a column top beam or plate.

[0021] The beneficial effects of the utility model are as follows:

[0022] The utility model realizes one-time integral casting of the structural column and the main structure by arranging a seam plate at the contact surface between the bottom of the structural column and the beam and the plate, and does not need to cast the structural column separately after the main structure is completed, thus saving a construction process and improving construction efficiency.

[0023] The utility model uses the seam plate to effectively isolate the structural column from the main structure, avoids the structural column from bearing vertical loads, thereby achieving the separation of the stresses of the structural column and the main structure, and ensuring the safety and stability of the structure.

[0024] The utility model has the advantages that the seam-pulling plate forms a concrete surface layer naturally after the concrete is poured, and there is no need to manually use mortar to seal the surface, which further reduces the construction steps and manpower input and simplifies the construction process.

[0025] The utility model discloses a patented construction column method that only reserves column longitudinal reinforcement dowels at the bottom. Compared with the traditional method, it reduces the binding process of the top longitudinal reinforcement and dowels, saves the amount of steel bars, shortens the construction period, and thus reduces material costs and labor costs.

[0026] The utility model is cast in one piece, thus avoiding quality problems that may be caused by multiple constructions and ensuring a tighter and firmer combination of the structural column and the main structure. BRIEF DESCRIPTION OF THE DRAWINGS
