Recycled block concrete prefabricated assembly type ring beam structure and construction method thereof

Abstract

The invention discloses a recycled block concrete prefabricated assembly type ring beam structure and a construction method thereof. The ring beam structure comprises recycled block concrete sections and non-disassembling formwork sections, the recycled block concrete sections comprise waste concrete blocks, longitudinal bars, ring beam inner stirrups and common concrete, the ring beam inner stirrups and the longitudinal bars are bound to form reinforcement cages, the waste concrete blocks are placed in the reinforcement cages, the common concrete is wrapped round the waste concrete blocks and the reinforcement cages, the two ends of the longitudinal bars extend out of the end faces of the recycled block concrete sections, the non-disassembling formwork sections comprise bottom plates and side plates that are connected with each other, each non-disassembling formwork section is placed between every two adjacent recycled block concrete sections, a cavity with the top open is defined by the bottom plates, the side plates and the end faces of the at least two adjacent recycled block concrete sections, the longitudinal bars of the at least two adjacent recycled block concrete sections are bound in the cavity, and the cavity is filled with the common concrete to be wrapped round the longitudinal bars.

Description

technical field [0001] The invention relates to the technical field of assembled ring beams, in particular to a recycled block concrete prefabricated assembled ring beam structure and a construction method thereof. Background technique [0002] The ring beam is a closed concrete beam member that is reinforced according to the structure along the horizontal direction of the masonry wall at the elevation of the cornice, window top, floor, crane beam top or foundation top surface of the house. It can improve the spatial rigidity of the house, increase the integrity of the building, improve the shear and tensile strength of masonry, and prevent damage to the house due to uneven settlement of the foundation, earthquakes or other large vibration loads. [0003] At present, most of the ring beams used on site are cast-in-place, but there are many problems in the cast-in-place ring beams. One is that the cast-in-place concrete is not easy to vibrate, resulting in honeycomb and pock...

AI Technical Summary

Problems solved by technology

One is that the cast-in-place concrete is not easy to vibrate, which leads to honeycomb and pockmarks; the other is that the on-site construction is likely to have the phenomenon that the steel bar binding and lap length do not meet the specification requirements, which affects the quality of the project; the third is that there is dust emission in the wet operation of the cast-in-place concrete and noise pollution, which does not conform to the concept of green environmental protection; fourth, it is difficult to guarantee the safety of pouring concrete in the same vertical plane; in addition, the masonry of the upper layer needs to wait until the ring beam concrete has a certain strength, which affects the construction efficiency
