Problems solved by technology

The on-site construction period is long and is greatly affected by seasons and weather
[0004] If the building adopts the traditional prefabricated structure (partly prefabricated + partly cast-in-place), the amount of on-site formwork is small, but the quality of part of the on-site poured concrete is difficult to control, and common quality problems such as honeycomb, pockmarked s

Example Embodiment

[0031] Embodiment 1: (This embodiment takes a single-story computer room as an example for description)

[0032] See Figure 1-3 In the figure, the fully prefabricated assembly structure of the present invention is composed of twelve prefabricated components, including two top plates 1, eight wall panels 2, and two bottom plates 3. Each prefabricated component is reserved with bolts embedded in the design according to the drawings. , Steel gaskets, rings, drip tanks, etc. Among them, prefabricated wall panels, top and bottom panels are spliced ​​together by two pieces. A 10mm assembly gap is reserved between the components of the assembly structure. The assembly connection between the components includes the parallel connection of the prefabricated concrete components and the connection of the vertical joints between the prefabricated wall panels and the top and bottom panels. Among them, the parallel connection of prefabricated concrete components refers to the connection bet...

Example Embodiment

[0043] Embodiment two:

[0044] The present invention also provides a construction method for the fully prefabricated assembly structure as described in the first embodiment, wherein the prefabricated components are poured and cured in the factory, and after the hoisting strength requirements are met, the prefabricated components are transported to the site for assembly construction. The construction process is: first fix the water-swellable rubber water-stop strip at the L-shaped interface of the prefabricated component, and then hoist the bottom plate, the wall plate and the top plate in sequence according to the construction plan. A 10mm assembly gap is reserved between the components; After fixing with a pair of tension bolts, apply a special sealant for concrete at the joints of the inner and outer sides first, and then pour cement-based grouting material from the top to make the two adjacent prefabricated components form an integral structure; External sealant, then pour ce...

Abstract

The invention belongs to the technical field of building construction and in particular relates to a fully-prefabricated structure and a construction method thereof. The fully-prefabricated structure comprises a top plate, peripheral wall boards and base plate concrete precast members, wherein an assembly clearance joint is preserved between every two adjacent concrete prefabricated members; joints connected with the concrete prefabricated members in parallel adopt L-shaped stagger-jointed lapping; in addition, the prefabricated wall panels are connected by embedded split bolts or connected by grouting and casting of reserved steel bars and matched holes; vertical joints between the prefabricated wall panels and the top plate and the base plate adopt grouting and casting connection through the reserved steel bars and the matched holes; water-expandable rubber water-stop strips are arranged in the reserved assembly clearance joints and are grouted with cement-based grouting materials; sealants are arranged on openings in two sides of the reserved assembly clearance joints. The fully-prefabricated structure and the construction method thereof disclosed by the invention have the advantages that the construction speed is high, the quality is easy to control, and materials such as a template scaffold are saved; the members are good in appearance quality and durability; field wet operation is reduced, so that environment friendliness is facilitated; the fully-prefabricated structure and the construction method thereof are suitable for construction of single-storey assembled buildings and multi-storey assembled buildings having no seismic requirements.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a fully prefabricated assembly structure and a construction method thereof, which are suitable for the construction of single-story assembly buildings and multi-layer assembly buildings without earthquake resistance requirements. Background technique [0002] Most of the traditional single-story and multi-storey buildings adopt brick-concrete structure. After the construction of the brick-concrete structure is completed, it is necessary to carry out the construction of plastering and insulation layers. The on-site construction period is long, greatly affected by seasons and weather, and the construction quality is difficult to control. Common quality problems such as hollowing and cracks in the plastering layer and insulation layer often occur. Uneven settlement of the foundation may even cause cracks in the wall, affecting structural safety. [0003] If...
