Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing.

[0026] When the steps of the concrete trestle bridge are connected with the floor, the connection at the joints can be carried out by the following steps.

[0027] (1) The trestle step structure is a layered structure, the bottom layer is a steel beam 8, on which a trestle floor 7 is arranged, and a layer of thermal insulation material 2 is laid on the trestle floor 7, and the concrete step structure 1 is laid on top of the thermal insulation material 2.

[0028] (2) Place embedded iron pieces 4 on the beams of the floor slab. The embedded iron pieces 4 are square iron sheets of 100mmx100mm, and are placed in grooves on the beams of the floor slab. The distance between the embedded iron pieces 4 is 500mm.

[0029] (3) After the construction of the trestle steps is completed, there is a certain distance between the deformation joints and the floor 6. First, the No. 26 galva...

Abstract

A deformable connection method and deformable connection structure between concrete trestle steps and floor, wherein the trestle steps are constructed in a layered structure, and embedded iron pieces are arranged on the beams of the floor; a certain distance is left between the trestle steps and the floor. Deformation joint; the iron sheet is installed on the upper end face 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; Asphalt wood fiber board is laid on the wire; cement mortar cushion is laid on the iron sheet; the profiled steel plate is covered on the cement mortar cushion; Leave a lateral gap; this gap is closed with a polyurethane sealing material after welding. The invention can meet the demand for deformation joints in large-scale projects, and at the same time plays the functions of settlement, shock resistance, expansion and contraction, and improves waterproof performance.

Description

technical field [0001] The invention relates to a building wall connecting method and a connecting structure, in particular to a deformable connecting method and a deformable connecting structure between steps and floors of a concrete trestle bridge. 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 en...
