Pouring device and method for beam-slab-column concrete engineering of different strength grades

Abstract

The invention relates to a pouring device for beam-slab-column concrete engineering of different strength grades, and belongs to the field of constructional engineering construction. A stirrup cage tobe poured comprises two beam stirrups arranged in a crossed manner, column stirrups are vertically inserted into the crossed positions of the beam stirrups, and the pouring device comprises an inclined baffle arranged on the beam stirrups in a sliding manner; and a core area is defined by the center of the baffle, the pouring device comprises a pouring tool extending into the core area and pouring concrete into the beam stirrups, and the pouring tool is connected to a discharging port of a distributing machine. The pouring tool extends into the core area, and the effect of facilitating pouring operation is achieved. The invention further discloses a pouring method of the beam-slab-column concrete engineering with the different strength grades, and the pouring method has the effects that construction joints of high-strength concrete in the core area and low-strength concrete connected with the core area are reduced, the high-strength concrete is prevented from flowing during construction, and the construction quality is enhanced.

Description

technical field [0001] The present application relates to the field of building engineering construction, in particular to a pouring device and method for beam-slab-column concrete works with different strength levels. Background technique [0002] In the reinforced concrete structure, the beam-column joints of the high-rise building frame structure are relatively complicated. Due to the results of load combination and internal force calculation, the concrete strength level of the vertical structure (column, wall) on the same floor is required to be higher than that of the horizontal structure (beam, slab). strength level of concrete. [0003] At present, when pouring the concrete core area, the following two construction methods are available: [0004] 1. Formwork barriers are used to support the boundary between high and low strength grade concrete, and high strength grade concrete is poured first, and then low strength grade concrete is poured after the formwork is remov...

AI Technical Summary

Problems solved by technology

[0004] 1. Formwork barriers are used to support the boundary between high and low strength grade concrete, and high strength grade concrete is poured first, and then low strength grade concrete is poured after the formwork is removed, so that many vertical components and horizontal components on the same floor are produced Construction joints will affect the quality of the project; for example, the basement exterior wall, the concrete strength level of the wall and the attached wall column is different, and this method of construction will easily cause leakage of the basement exterior wall;

[0005] 2. Use pumped commercial concrete to pour, first pour high-strength concrete to the top, and then pour low-strength concrete, but because the slump of pumped concrete is generally 160-180mm, it flows far after being vibrated, so The amount of high-strength grade concrete will increase a lot, the workload is heavy, and the time is not well grasped. After a long time, the edge concrete of high-strength grade concrete has finally set, and the low-strength grade concrete has not been covered and poured, which will make the junction of high-strength grade concrete and low-strength grade concrete. If the time is too short, the high-strength concrete has not yet initially set, and the low-strength concrete has already been poured, which will easily cause the low-strength concrete to mix into the high-strength concrete, and the Reduce the strength of high-strength concrete and affect the quality of the project

[0006] In view of the related technologies mentioned above, the inventor believes that the first construction method may generate construction joints, and the second method reduces the strength of high-strength concrete, both of which affect the quality of the project
