Assembled L-shaped composite wallboard self-tapping screw block and post-cast strip combined connection structure and construction method

Abstract

The invention discloses an assembly type L-shaped composite wallboard self-tapping screw set block and post-pouring strip combined connection structure and a construction method, and belongs to the technical field of assembly type concrete building structure engineering. Comprising a self-tapping screw set block which comprises force transmission steel plates welded on single-row reinforcing meshes of inner and outer concrete thin plates of an L-shaped upper L composite wallboard and an L-shaped lower L composite wallboard, and a built-in steel structure concrete thin wallboard block with the thickness of the outer contour concrete thin plate of a force transmission steel plate area connected by self-tapping screws is adopted as a connecting steel plate; the post-pouring strip is a reinforced concrete thin wallboard strip which is formed by overlapping and pouring fine aggregate concrete on the post-pouring strip, wherein the reinforced meshes are reserved on the concrete thin plates of the prefabricated L-shaped upper and lower composite wallboards; the L-shaped constructional column is a concrete embedded column located at the inner corner of the composite wallboard. The combined connection structure is an integration of a self-tapping screw block, a cast-in-place strip and an L-shaped embedded column connection structure, and has the remarkable advantages of earthquake resistance, high bidirectional shearing force, high bending moment and high torque capacity, and efficient cooperative stress.

Description

technical field [0001] The invention relates to a combined connection structure and method of a self-tapping nail block and a post-casting strip of an assembled L-shaped composite wallboard, and belongs to the technical field of assembled concrete building structure engineering. Background technique [0002] The technology research and development of ultra-low energy consumption houses has drawn great attention from the engineering community at home and abroad. However, at present, the construction technology of low-storey and ultra-low energy consumption houses in villages and towns, especially the prefabricated construction technology, is very lacking. [0003] Technical bottlenecks: (1) The assembly of the L-shaped wall at the corner of the building is complicated. The L-shaped wall at the corner is subjected to bending, shearing and torsional earthquakes, so it is necessary to set up corner structural columns and one-shaped composite wall. The body assembly method canno...
