Embodiment

[0030] This example figure 1 As shown, in order to make it easier to see the structure of the post-pouring belt, the waterproof layer and the leveling layer are partially sectioned, and only a part of the backfill soil is drawn schematically. During specific implementation, the main structure 1 is constructed first, and a post-casting belt 2 with a width of 800 mm is reserved between the main structures 1 . After the construction of the main structure 1 is completed, the sealing steel plate 3 is pasted on the main structure 1 on both sides of the post-casting tape 2 with epoxy structural glue 8 . The thickness of the sealing steel plate 3 is 50mm, and it is advisable that each side of the sealing steel plate 3 exceeds the side line of the post-casting tape 2 by 200mm. There should be no gap between 1; after the sealing steel plate 3 is pasted, a layer of steel wire mesh 4 is laid on the outer surface of the sealing steel plate 3. Cracks are formed between the concrete mix...

Abstract

The invention discloses a method and structure for simultaneous conducting on waterproof construction of a post-cast strip and a main body structure. The method comprises the following steps of blocking steel plate pavement, steel wire mesh hanging, screed-coat construction, waterproof layer construction, back-filling construction, concrete pouring construction and the like, and through the steps, the post-cast strip and the main body structure are integrally constructed. According to the method and structure for simultaneous conducting of waterproof construction on the post-cast strip and the main body structure, waterproof construction is simultaneously conducted on the post-cast strip and the main body structure; the construction technique is simple, construction is convenient and quick, and cost is low; and the project needing earthing and back filling to be urgently conducted can be met, and the engineering construction period is ensured. The method and structure for simultaneous conducting of waterproof construction on the post-cast strip and the main body structure is suitable for the occasion that earthing and back filling are urgently met by a skirt building or a basement of engineering such as multilayer and frame-shear structures.

Description

technical field [0001] The invention relates to a method and a structure for simultaneous waterproof construction of a post-cast belt and a main structure, and belongs to the technical field of construction engineering. Background technique [0002] In order to prevent cracks caused by uneven settlement or uneven self-shrinkage of cast-in-place reinforced concrete structures, the construction specification for concrete structures stipulates that in order to adapt to environmental temperature changes, concrete shrinkage, uneven settlement of structures and other factors, beams, slabs ( The concrete belt with a certain width reserved in structures such as foundation slabs, walls, etc. and poured after a certain period of time is called a post-casting belt. According to the requirements of the regulations, the post-pouring belt must be refilled at least 60 days after the construction of each layer after pouring and tamping. The conventional post-casting construction technol...
