Reinforcement type prefabricated assembly type shear wall structure and construction method thereof

Abstract

The invention discloses a reinforcement type prefabricated assembly type shear wall structure. Pre-stressed steel strands penetrate into an upper layer prefabricated wall and a lower layer prefabricated wall connected with the upper layer prefabricated wall adjacently. The invention further discloses a construction method of the reinforcement type prefabricated assembly type shear wall structure. According to the special construction process of a tooth space type connection structure of the assembly type shear wall, in the construction process of the upper layer prefabricated wall, the pre-stressed steel strands are adopted for connecting the adjacent upper layer prefabricated wall and the lower layer prefabricated wall, so that the upper layer prefabricated wall is stabilized on the lower layer prefabricated wall in the period that a concrete structure is cast, temporary supports do not need to be arranged any more, construction is convenient, performance is reliable, and the problems that the assembly type shear wall is difficult in connection construction on site and expensive in manufacturing cost are solved. Meanwhile, an existing connection structure is strengthened.

Description

technical field [0001] The invention relates to a prefabricated shear wall structure system and a construction method thereof, in particular to a reinforced prefabricated shear wall structure and a construction method thereof. Background technique [0002] In the context of the era of green low-carbon, energy saving and emission reduction, the traditional cast-in-place structural system will gradually be replaced by the new prefabricated structural system and high-rise prefabricated houses are an important way to build land-saving, energy-saving, and environmentally-friendly houses, so it is particularly necessary to research and develop prefabricated shear wall structural systems. [0003] At present, the vertically distributed steel bars of the prefabricated wall of the existing prefabricated shear wall structure mostly use sleeve grouting connection, steel bar welding connection and indirect lap joint grout anchor connection and other connection methods. Most of the above...

AI Technical Summary

Problems solved by technology

Setting the cogged shear key can effectively improve the shear bearing capacity of the prefabricated shear wall structure, and can also enhance the occlusal strength of the prefabricated wall and the post-cast concrete, but the vertically distributed steel bars of the prefabricated wall at the cog can freely overlap , when the length of the lap does not meet the requirements of the code, this kind of lap is an unequal-strength connection, the strength of the vertically distributed steel bars in the wall is not fully exerted, and the seismic ductility of the components is weakened, so the connections at the ends of the prefabricated walls on both sides have necessary to strengthen

[0005] In terms of construction procedures, the existing prefabricated shear wall structure is connected by sleeve grouting, steel bar welding and indirect lap joint grout anchors. When hoisting and installing prefabricated shear wall panels, the construction of the same floor has been completed. The floor slab can be used as the lower stress point supported by the prefabricated shear wall panel; while the upper and lower wall panels of the prefabricated shear wall structure with cogged connection are connected by pouring concrete in the reserved cogged area of ​​the floor to connect the upper and lower panels Yes, for the convenience of operation, the concrete in the alveolar area is poured at the same time as the post-casting layer of the floor slab, so the prefabricated shear wall on the upper floor lacks effective support during installation
