Embodiment 1

[0028] The construction method of the cast-in-place cantilevered bay window panel of the present invention comprises the following steps:

[0029] (1) Measuring and setting out

[0030] According to the requirements of the design drawings, the plane position line and elevation control line where the window sill is located will pop up.

[0031] (2) Concrete chisel

[0032] Since the formwork is installed on the poured floor of the lower window sill, it is the handover of old and new concrete, so the floor where the lower window sill is located should be chiseled first, and the surface layer of cement exposed stones should be chiseled, and rinsed with clean water.

[0033] (3) Set up formwork support system

[0034] see now figure 1 , figure 1 It is a schematic structural diagram of the formwork support system of the cantilevered bay window slab according to the embodiment of the present invention, the floor slab 2 to be poured, the bay window sill 7 lowered, and the floor s...

Abstract

The invention provides a construction method of a cast-in-place cantilever bay window plate. The construction method is characterized by comprising the following steps of a, surveying and setting out,b, concrete chiseling, c, formwork supporting system erecting, d, formwork reinforcing, and e, concrete pouring. The construction method of the cast-in-place cantilever bay window plate has the advantages that construction of the cantilever bay window plate and a main body structure are synchronous, the construction cost of a secondary structure is saved, the engineering quality is safe and reliable, the structural quality is better guaranteed, the construction efficiency is improved, and the engineering cost is reduced.

Description

technical field [0001] The invention relates to a method for pouring concrete slabs, in particular to a construction method for cast-in-situ cantilevered bay window panels. Background technique [0002] In order to achieve the beautiful effect of building facades in architectural design, certain shape changes are usually designed. Cantilevered components are commonly used components. Residential houses generally have bay window panels, and some designs use a bay window panel every few floors. , leading to difficulties in the construction of bay window panels. In the current construction process of the industry, secondary pouring is used for construction, and the construction quality is not enough. However, the bay window panel structure is a component that must be used for a long time in architectural design practices. It should be paid attention to according to the primary structure and the construction quality should be strictly controlled. [0003] Therefore there are ab...
