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 surface, hollowing, and leaking reinforcement often occur. The waterproof effect of the joints of the external wall is poor, and it is difficult to ensure the flatness of the wall at the joints, so it needs to be plastered again
Because the concrete pouring and curing still needs to be done on site, the construction period is still long and is greatly affected by seasons and weather

Embodiment 1

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

[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 panels 1, eight wall panels 2, and two bottom panels 3, and each prefabricated component is reserved and pre-embedded with bolts according to the drawing design , Steel gaskets, rings, drip tanks, etc. Among them, the prefabricated wall panels, roof panels and bottom panels are respectively spliced ​​by two pieces. An assembly gap of 10 mm is reserved between components of the assembly structure. The assembly connection between the components includes the parallel connection of the concrete prefabricated components and the connection between the prefabricated wall panels and the vertical joints between the top and bottom panels. Among them, the parallel connection of concrete prefabricated componen...

Embodiment 2

[0044] The present invention also provides a construction method for a fully prefabricated assembly structure as described in Embodiment 1, wherein the prefabricated components are poured and cured in the factory, and after meeting the lifting strength requirements, the prefabricated components are transported to the site for assembly construction, specifically The construction process is as follows: first fix the water-expandable rubber water-stop strip at the L-shaped interface of the prefabricated component, and then hoist the bottom plate, wall plate and roof plate in sequence according to the construction plan, and reserve a 10mm assembly gap between the components; After being fixed with tension bolts between the two sides, apply concrete sealant at the joints of the inner and outer sides first, and then pour cement-based grouting material from the top, so that the two adjacent prefabricated components form an integral structure; the joint between the wall and the bottom p...

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...
