Bolt connection assembly type L-shaped double-steel-plate concrete composite wall

Abstract

The invention discloses a bolt connection assembly type L-shaped double-steel-plate concrete composite wall, and belongs to the field of constructional engineering. The bolt connection assembly type L-shaped double-steel-plate concrete composite wall comprises a first dumbbell-shaped connection double-steel-plate concrete composite wall (hereinafter referred to as a first wall), a second dumbbell-shaped connection double-steel-plate concrete composite wall (hereinafter referred to as a second wall) and connection bolts. Each of the first wall and the second wall comprises perforated double steel plates, dumbbell-shaped connection pieces, toggle pins and filled concrete. Bolt holes are pre-formed in the first wall, built-in threaded sleeves are welded to corresponding positions, and bolt holes are pre-formed in the second wall; and the connection bolts sequentially penetrate through the bolt holes of the second wall and the first wall and are screwed into the built-in threaded sleeves of the first wall, the first wall and the second wall are perpendicularly connected to form an L shape, and finally, filling concrete is poured on the construction site. The invention has the remarkable advantages of being simple construction process, low construction environment dependence and safe and reliable in connection. Flexible application and connection of the building walls can be realized by adjusting the lengths and the widths of the wall limbs of the first wall and the second wall.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a bolt-connected assembled L-shaped double steel plate concrete composite wall. Background technique [0002] At the corner of the building, in order to avoid the indoor stare, an L-shaped composite wall with the same width as the two limbs is generally used for aesthetic considerations. The traditional L-shaped opening double-steel plate composite wall is generally connected by welding, which can easily cause stress concentration of the steel plate and increase the difficulty of on-site construction. Since the interaction force between the vertical and horizontal walls at the connection part of the L-shaped composite wall is very small, bolt connection can be considered. Contents of the invention [0003] Aiming at the deficiencies in the prior art presented in the background art above, the present invention provides a bolt-connected assembled L-shaped double...
