Deformable connection structure between concrete trestle steps and floors

Abstract

A deformable connection structure between the steps of the concrete trestle and the floor, wherein the steps of the trestle are structured in a layered structure, and pre-embedded iron pieces are placed on the beams of the floor; deformation joints at a certain distance are left between the steps of the trestle and the floor; It is installed on the upper surface of the concrete step structure and the floor slab; the iron sheet forms a U-shaped structure in the deformation joint, and the U-shaped iron sheet extends in the deformation joint; the U-shaped iron sheet is filled with asphalt hemp; the asphalt hemp is paved with asphalt Wood wool board; cement mortar cushion is laid on the iron sheet; shaped steel plate is covered on the cement mortar cushion, and the end of the steel plate near the floor is welded and fixed with the embedded iron parts; a transverse gap is reserved between the steel plate and the floor; The gap is sealed with polyurethane sealing material after welding. The invention can meet the demand for deformation joints in large-scale projects, and at the same time play the roles of settlement, shockproof, expansion and contraction, and improve waterproof 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...
