Concrete explosion-proof wall with embedded steel framework

Abstract

The invention relates to concrete explosion-proof wall with an embedded steel framework. The wall comprises a wall body (1) and a foundation (2), wherein the foundation (2) together with the wall body (1) are integrally cast with concrete, and a steel framework is embedded between the wall body (1) and the foundation (2). The wall is characterized in that the steel framework consists of two side vertical columns (4), a plurality of transverse beams and an embedded steel piece (3) of the foundation (2), wherein the two ends of each transverse beam are respectively, horizontally and fixedly connected with the two side vertical columns (4) according to different elevations, each vertical column (4) is made of H-shaped steel, the surface direction of an H-shaped steel wing flange (16) is consistent with the length direction of the wall body (1), each transverse beam is made of T-shaped steel, the embedded steel piece (3) of the foundation (2) is fixedly connected with the lower side of the bottom transverse beam (5), the upper side of each transverse beam is provided with a plurality of screw rod holes (15), a screw rod (8) penetrates through each screw rod hole (15), the top part of each screw rod (8) is fixedly connected with the top transverse beam (7), and the bottom of each screw rod (8) is fixedly connected with the embedded steel piece (3).

Description

technical field [0001] The invention belongs to the field of building protection, in particular to a novel assembled concrete explosion-proof wall embedded with a steel frame, which is suitable for use in front of important public civil buildings. Background technique [0002] Unstable factors such as religion, ethnic conflicts, economic frictions, and territorial disputes are the root causes of various terrorist incidents. According to relevant statistics, in recent years, terrorist attacks carried out by means of explosions are on the rise, with an average of about 300 cases per year, and the scale and impact are getting bigger and bigger. At the same time, explosive terrorist attacks mainly occur in crowded public places, and the main methods of attack are car bombs and suicide bombings. Therefore, the use of engineering anti-terrorism measures can greatly reduce the harm caused by terrorist attacks, and it is the consensus of the majority of engineering and technical pe...
