Deformable connection structure of concrete landing stage steps and building surface

Abstract

The invention discloses a deformable connection structure of concrete landing stage steps and a building surface. Landing stage steps adopt layered structures, and an embedded iron piece is arranged on a beam of a floor slab; deformation joints with certain distances are reserved between the landing stage steps and the floor slab; a full iron sheet is mounted on upper end surfaces of the concrete step structure and the floor slab; the iron sheet is in U-shaped structures in each deformation joint and extends in each deformation joint; the U-shaped iron sheet is filled with bituminous hemp fibers; a bituminous wood wool slab is laid on the bituminous hemp fibers; a cement mortar bedding cushion is laid on the iron sheet and covered with a section steel plate; an end part, close to the building surface, of the steel plate is welded and fixed with an embedding iron piece; a transverse space is reserved between the steel plate and the building surface; and the space is sealed with a polyurethane sealing material after welding. The deformable connection structure can meet requirements for deformation joints in a large-scale project, has the functions of sedimentation, shock-proofing and expansion at the same time, and improves the drainage performance.

Description

technical field [0001] The invention relates to a building wall connection structure, in particular to a deformable connection structure between concrete trestle steps and floors. Background technique [0002] Trestle is a station, port, mine or factory, used for loading and unloading goods or getting on and off passengers, or a temporary bridge structure specially used for construction site traffic, mechanical layout and overhead operations. In civil engineering, temporary bridge facilities built for transporting materials, equipment, and personnel are divided into wooden trestle bridges and steel trestle bridges according to the materials used. The trestle in a railway ferry is a bridge building for rolling stock to drive on and off the ferry. [0003] At present, the trestle structure composed of steel structure and concrete is widely used in railway engineering, tunnel construction, electric power engineering and other fields. Since the preforming can only be formed in...
