Step S15: every four adjacent construction point 102 are called a grid, often install the precast plate 16 of a grid, then carry out the construction of time beam 15, installs precast plate 16 and time beam 15 successively along construction direction.

Step S16: lay this layer of overlapping layers reinforced mesh (not shown) on grid, then casting beams, bean column node and this floor plate overlapping layers concrete, flush with this Rotating fields design elevation.

Above-mentioned step S16 can adopt in another way: first casting beams and bean column node concrete, and flushes with the absolute altitude of precast plate 16, carries out next layer of construction after concrete strength meets.

Meanwhile, after its later layer structural strength meets the demands striking 13, tear column template 11 and beam forms 12 open, re-lay this layer of overlapping layers reinforced mesh (not shown), cast-in-place whole flooring overlapping layers (not shown).

The second embodiment of the present invention is for install with layer: what the mode of installing with layer utilized is same layer small lifting equipment, it is not highly higher than floor height, run on this layer with layer small lifting equipment, the precast plate (during lifting, component inside edge is outer in base scope) of this layer is installed.

Refer to Fig. 7 and Fig. 9, second embodiment of the invention comprises the following steps:

Step S21: post reinforcing bar 20 is set, post reinforcing bar 20 surrounds by erection column template 21;

Step S22: set up support 23, then mounting rail template 22, at beam forms 22 inner mounting rail reinforcing bar (not shown), then build post, beam concrete;

Step S23: install precast plate 26; And

Step S24: repeat above-mentioned steps, carry out the construction of next floor.

The detailed step of above-mentioned construction method is as follows:

S21: refer to Fig. 8 and Figure 10, one construction plane 201 is provided, this construction plane 201 is a horizontal plane, this construction plane 201 is along X, Y-direction is arranged to the construction point 202 of matrix, each construction point 202 arranges multiple post reinforcing bar 20, then post reinforcing bar 20 surrounds by erection column template 21 in the vertical direction, form the cavity that the cuboid of an opening is arranged at a top, and close proximity between the corresponding side of each column template 21.

S22: refer to Fig. 9 and Figure 10, set up multiple support 23 between two adjacent in the x, y direction post reinforcing bars 20, the top of this support 23 is parallel to horizontal plane, and lower end is butted on construction plane 201.In the top mounting rail template 22 of support 23, during mounting rail template 22, first install the beam forms 22 of bottom, mounting rail reinforcing bar (not shown) on the beam forms 22 of bottom, finally just installs the beam forms 22 of two sides.Then at the inner colligation beam steel of beam forms 22, the two ends of this beam steel are inserted in corresponding post reinforcing bar 20, first build post, beam concrete, after concrete intensity enough supports, remove column template 21, beam forms 22, thus form the general frame of post and beam.

S23: refer to Figure 10, installs precast plate 16, installs precast plate 16, utilize same layer small lifting equipment 27 to install precast plate 16 between the support 23 of beam forms 22 correspondence.This with layer small lifting equipment 27 height lower than floor height, this layer is run on layer small lifting equipment 27, (the present embodiment adopts the precast plate 16 described in the first embodiment to install the precast plate 16 of this layer, the frame for movement mentioned refers to view and the numbering of the precast plate 16 that first embodiment of the invention provides), the suspension hook 163 of precast plate 16 can be connected with hook when lifting, by two of precast plate 16 vertical rib 162 two beams that frame is adjacent in the Y direction respectively.During lifting, precast plate 16 inside edge is outside base scope.

Precast plate is installed in step S23 carry out after beam column concrete strength meets the demands and only removes side form and not load-bearing striking; Step S23 installs precast plate and also can meet the demands at beam column concrete strength and carry out after stripping and support.

After concrete strength meets, carry out one deck construction thereafter, meanwhile, after superstructure intensity meets, tear support 23 open, lay this layer of overlapping layers reinforced mesh, cast-in-place whole flooring overlapping layers.

Relative to prior art, the invention has the advantages that:

1. a kind of assembled architecture of the present invention by the construction method of prefabricated superimposed sheet when reaching certain scale, due to without the need to setting up full hall scaffold, a large amount of circulation material, time and cost of labor can be saved, prefabricated superimposed sheet after shaping appearance effect is good, without the need to carrying out again plastering, the finishing work such as furred ceiling, save manpower, constructional materials cost in a large number.
