Embodiment Construction

[0037] The present invention will be further described below in conjunction with accompanying drawing.

[0038] A kind of PCF plate construction method for prefabricated building, comprises the following steps:

[0039] 1) In the production of PCF boards, φ80 through holes are reserved for PCF boards during production as hoisting holes during hoisting. For the reserved holes of the outer frame and wall parts, after the construction is completed, fill the insulation boards in the hoisting holes, seal them with waterproof mortar, and brush the outside with waterproof paint to ensure sealing;

[0040] 2) Base level cleaning, setting out, and adjusting the elevation. Clean up the PCF board and the root of the wall to be hoisted in advance.

[0041] Lay out the lines, release the edge lines at both ends of the PCF outer slab and the edge lines and control lines of the cast-in-place part of the wall, and use the black ink line to bounce on the structural floor. It is necessary to e...

Abstract

The invention discloses a construction method of a PCF board for a fabricated building. The construction method comprises the following steps that in the production of the PCF board, a penetrating hole is reserved as a hoisting hole for hoisting, base course cleaning, laying off and elevation adjusting are conducted, a vertical connecting plate is fixed, a bed mortar is laid at the bottom of an insulation board of the PCF board, the bed mortar extends out of the insulation board, and the height of the bed mortar is higher than the elevation; the PCF board is vertically hoisted by using the hoisting hole; and after the PCF board is fixed by an inclined support, the perpendicularity of a PCF board component is accurately corrected and adjusted, then the connection is conducted firmly, and unhooking is conducted after rechecking the sideline, perpendicularity, flatness and top elevation of the PCF board. According to the construction method, the PCF board can be vertically hoisted duringhoisting, the problem of collision with an external frame during the previous inclined hoisting is solved, the safety during hoisting is greatly improved, and the efficiency is greatly improved compared with the inclined hoisting; and the problems of rectification of defects in the later decoration of an external wall and an internal wall and the like caused by the insufficient installation accuracy of the PCF board component are solved, and the benefit is improved.

Description

technical field [0001] The invention discloses a PCF board construction method for an assembled building, belonging to the technical field of building construction methods. Background technique [0002] In recent years, prefabricated buildings have shown new vitality due to their advantages of diversified design, modernization of functions, factory-based manufacturing, assembly-based construction, and time optimization. Among them, prefabricated buildings are very popular. The original design of high-rise residential buildings is generally a shear wall structure, but now the prefabricated high-rise residential buildings are designed as an assembled integral shear wall structure. In part of the design, in order to form the outer wall and thermal insulation at one time, the vertical components are split and designed as "sandwich insulation board outer wall", that is: inner panel + insulation layer + outer panel. Since the main stress nodes need to be cast-in-place, so A PCF p...
