Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings.

[0034] Such as Figure 1~6 Shown is a platform-FRP sheet connection structure of a precast concrete beam-slab system, the precast concrete beam-slab system includes columns 1, inner beams 2, side beams 3, inner precast panels 4 and corner precast panels 5, inner beams 2 and side beam 3 are supported on the column 1 or other inner beams 2 or side beams 3 according to the existing mature technology, the inner prefabricated panel 4 and the corner prefabricated panel 5 are placed on the side of the inner beam 2 and / or side beam 3, and the inner The prefabricated slab 4 and the corner prefabricated slab 5 have the same thickness.

[0035] In order to facilitate the shelving of the inner prefabricated slab 4 or the corner prefabricated slab 5, the inner beam 2 protrudes a quadrangular column-shaped platform 9 from its two sides, and the height of the platform 9 from the top s...

Abstract

The invention provides a cantilever platform-FRP sheet connecting structure and method for a precast concrete beam-slab system. A full-thickness precast slab is placed on a cantilever platform on theside face of a floor beam, wherein an adjusting seam with the width of about 20mm is formed between the precast slab and the floor beam, and an adjusting seam with the width of about 20mm is formed between the precast slab and the floor beam; the adjusting seams are filled with high-strength micro-expansion mortar; FRP sheets for connection are pasted to the top faces of the seams between the precast slab and the floor beam and the top faces and the bottom faces of the seams between the precast slab and the floor beam; and the fiber direction of the FRP sheets is perpendicular to the longitudinal direction of the seams. The problems that due to the fact that ribs are formed on the periphery of an existing slab type precast component, the side formwork of the precast component is complex, the production efficiency is low, and transportation and hoisting operation is difficult are solved; the problems that due to the fact that existing precast slabs are stacked and poured, a large amountof wet operation is caused on site, and the thickness of a floor is too large are solved; and in addition, the precast slabs are easy to assemble in place on site, pasting connection construction isconvenient and fast, and the excellent waterproof and anti-seepage effects are achieved at the seams.

Description

technical field [0001] The invention relates to a platform-FRP sheet connection structure and method of a prefabricated concrete beam-slab system, which belongs to construction engineering technology. Background technique [0002] In recent years, with the continuous improvement of people's requirements for living conditions and living environment, the construction industry has developed rapidly. However, the development of the construction industry has caused serious resource consumption and environmental pollution, forcing people to seek a new way out of the construction industry. At present, the industrialization of buildings characterized by prefabricated buildings is one of the key ways to achieve low-carbon and sustainable development in the construction industry. [0003] In prefabricated buildings, the connection mode between structural components has a crucial influence on the efficiency of prefabricated and assembled construction and the mechanical properties of s...
