Assembly type ecological inner wall and convex foundation beam self-tapping screw aggregate connecting structure and construction method

Abstract

The invention discloses a fabricated ecological inner wall and convex foundation beam self-tapping screw aggregate connecting structure and a construction method, and belongs to the technical field of fabricated concrete structures. The self-tapping screw block is a steel-concrete combined block which is formed after a foundation beam force transmission steel plate and an ecological wallboard force transmission steel plate and also serves as a connecting steel plate are connected through self-tapping screws, the steel-concrete combined block is 40 mm in steel structure outline, reinforcing bars of the convex foundation beam are convex double-limb hoop reinforcement cages, and tenons protruding in sections of the foundation beam are embedded into corresponding grooves in the bottom of the ecological wallboard. A tongue-and-groove meshed connecting structure is formed, earthquake shearing force in the wall plate direction can be effectively resisted, slippage of the bottom of the wall plate is restrained, and the wall plate can be conveniently placed in place. The technical problem that the upper surface of a traditional foundation beam is flat and is not beneficial to restriction of the foundation beam on sliding of the ecological wallboard is solved, and the ecological wallboard and convex foundation beam self-tapping screw set block concentrated force transfer connecting structure, the wallboard and convex foundation beam tongue-and-groove meshing structure and the high-performance mortar continuous force transfer connecting structure are combined. And the technical advantage of cooperative and efficient stress is achieved.

Description

Technical field [0001] The present invention relates to a prefabricated ecological interior wall and convex foundation beam self-tapping nail block connection structure and practice, belongs to the field of prefabricated concrete structure technology. Background [0002] At present, the construction technology of low-level ultra-low-energy houses in villages and towns, especially the construction technology of prefabricated ultra-low-energy-consumption low-rise houses, is very lacking. The technical bottlenecks existing in the existing technology are: [0003] (1) The connection between the traditional cast-in-place shear wall and the foundation beam is a cast-in-place concrete connection, with a large amount of wet work, a slow construction speed, and an environmental pollution problem with large construction waste emissions and loud noise in the construction process. (2) The traditional technology of connecting steel bars with the foundation sleeve of the traditional prefabrica...

AI Technical Summary

Problems solved by technology

[0003] (1) The connection between the traditional cast-in-place shear wall and the foundation beam is a cast-in-place concrete connection, which requires a large amount of wet work and slow construction speed. During the construction process, there are environmental pollution problems such as large discharge of construction waste and high noise

(2) The traditional prefabricated shear wall and foundation sleeve connection steel bar technology is expensive and not suitable for the connection of prefabricated ecological interior walls and foundation beams

(4) The price of self-tapping screws is relatively low, which is very suitable for the assembly of reinforced concrete frame ecological wall panels and foundation beams, but there is no matching connection structure before
