Description

Construction method for cast-in-place area steel bars of integrally-assembled shear wall structure
Technical Field
The invention relates to the technical field of buildings, in particular to a steel bar construction method, and particularly relates to a construction method of a cast-in-place structural steel bar of a connecting member in an integrally assembled shear wall structure.
Background
The prefabricated concrete structure is one of the important directions of the development of the building structure in China, compared with the construction of a cast-in-place concrete structure, the prefabricated concrete structure is produced by prefabricating and processing in a factory, is transported to a construction site by a transportation tool, and is hoisted in place by a tower crane or a hoisting machine. This can improve the efficiency of construction, reduces the wet operation of job site, is favorable to green construction. At present, the assembled shear wall is widely popularized in an assembled building structure due to the advantages of good integrity, excellent bearing capacity, high rigidity and the like.
The prefabrication rate of the fabricated shear wall structure building at the present stage is up to more than 40%, but the cast-in-place structure has a volume of nearly 60%. In the connecting area of the prefabricated component and the cast-in-place structure, the construction method of the cast-in-place structural steel bars is different from the traditional cast-in-place structure, for example, how the steel bars are turned, how the steel bars are connected with the reserved steel bars of the component, and how the steel bars are installed in the sequence, which is a new problem in the construction process of the steel bars of the cast-in-place area of the existing fabricated structure.
Because the cast-in-place area steel bar construction of the fabricated structure is provided, the cast-in-place area steel bar construction of the fabricated structure is carried out after meeting the cast-in-place structure at the present stage, the steel bar construction of the cast-in-place area is difficult to standardize and unify, and the construction standards are inconsistent.
The construction sequence of the traditional wall column steel bars is as follows: reserved wall column steel bars → through stirrups → wall column steel bar connection → stirrup binding. The construction sequence of the traditional beam slab steel bars is as follows: and (3) beam reinforcement → reinforcement at the bottom of the floor slab → arrangement of a reinforcement split heads → reinforcement of the surface layer. When the cast-in-place structure reinforcing steel bars of the connecting components in the integrally assembled shear wall structure are constructed according to the traditional reinforcing steel bar construction sequence, the condition that the collision of the reserved reinforcing steel bars of the components and the cast-in-place structure reinforcing steel bars leads to construction inconvenience and the condition that the construction sequence of the cast-in-place structure reinforcing steel bars is disordered can occur, so that the construction period is delayed.
The Chinese application CN113738023A discloses a semi-prefabricated semi-cast-in-place constructional column and an assembly structure and a construction method thereof, which comprises an upper structural beam, a constructional column and a lower structural beam, wherein vertical downward positioning steel bars are pre-embedded on the upper structural beam, the constructional column is the semi-prefabricated semi-cast-in-place constructional column, constructional column planting bars are implanted on the lower structural beam, the positioning steel bars are placed in a reserved groove of the column body, the bottom of the supporting steel bars is supported on the lower structural beam, vertical steel bars of the column body are connected with the constructional column planting bars, the reserved groove is filled with grout, and concrete is poured in a cast-in-place section.
For another example, chinese invention CN106682266A discloses a method for processing reinforcing steel bars at cross steel reinforced column beam nodes based on BIM, which includes performing simulated lofting on the reinforcing steel bars of columns and beams at cross steel reinforced column beam positions in advance through the BIM technology, setting a supporting plate at an appropriate position of a flange in advance, setting a connecting plate at an appropriate position between webs, and setting arrangement of main reinforcing steel bars with different diameters of the beams according to the lengths of the supporting plate and the connecting plate, so as to reduce the amount of reinforcing steel bars, optimize the arrangement of the reinforcing steel bars of the beams and the columns, and ensure that the length of the welding seam of the main reinforcing steel bars of the beams above the supporting plate meets the requirements.
However, the above patent applications all have a problem that the conventional wall column steel bar construction and the fabricated steel bar construction are not completely distinguished, so that a construction period may be delayed and disordered due to lack of standardization during construction, which is not favorable for improving the construction efficiency.
This application aims at the construction model to above-mentioned problem, standardized prefabricated component and cast-in-place section between to when the construction, construct according to standardized model and then improve the efficiency of construction, reduction of erection time.
