Deformable connection method and connection structure of concrete trestle floor

Abstract

The invention discloses a deformable connection method and a connection structure of concrete landing stage building surfaces. Deformation joints with certain widths are arranged between two landing stage building surfaces; a full iron sheet is used for sealing the lower end surface of the connection position of the landing stage building surfaces; the length of the iron sheet connected to the lower end surface between the deformation joints is larger than the actual lengths of the deformation joints, that is, the iron sheet connected to the lower end surface has certain surpluses; a waterproof coiled material is added on the iron sheet, so that a secondary waterproof function is realized; a cement mortar bedding cushion is laid on the waterproof coiled material; and the deformation joints on the waterproof coiled material are sealed with an asphalt mastic material. The deformable connection method and the 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 connection method and a connection structure of building walls, in particular to a deformable connection method and a connection structure of concrete trestle 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. Trest...
