Description
Technical field
The present invention relates to the realm of building construction, specifically a kind of installation method of assembled architecture precast stair.
Background technology
Prefabricated assembling type reinforced concrete stair refer to that the stair being put together installed by the component with precast plant's production or field fabrication.Industrialized construction level can be improved using prefabricated assembled stair compared with cast-type reinforced concrete stairs, save template, simplify procedures, greatly the reduction of erection time.But globality, shock resistance due to prefabricated assembling type reinforced concrete stair, not as good as cast-in-situ steel reinforced concrete stair, therefore the mounting process of precast stair is even more important.
Content of the invention
It is an object of the invention to, improve the installation effectiveness and installation quality of precast stair.
In order to achieve the above object, the present invention is realized in：
A kind of installation method of assembled architecture precast stair；It is characterized in that：Comprise the steps：
Step 1, installation prepare；
Step 1.1, it is familiar with construction drawing, checks verification component numbering, determine installation site, and lifting sequence is numbered；
Step 1.2, according to construction drawing, eject stair and control line be installed, control line and absolute altitude are checked；Wherein, the reserved 20mm spaces of stair side identity distance structure wall, are the coat of plaster headspace of follow-up just dress；According to the reserved 100mm spaces of banister installation requirement between bench；
Step 1.3, staristep upper and lower opening ladder Liang Niutuichu with C30 pea gravel concretens seat starch；
Pre-buried to general hanger and staircase boards lifting inner nut is connected with bolt, checks shackle snap ring before lifting, can continue slow lifting after confirming firmly by the hoisting prefabricated staircase boards of step 1.4, level；
Step 2, stair bottom support system are installed；
When precast stair is lifted, the cast-in-place bracket concrete intensity of stair is also not up to design requirement, needs to make temporary support in stair bottom installation support system；Temporary support is set up using steel pipe scaffold, and rod end arranges top bracketing, and top bracketing is connected with jacking piece with 4 M12 bolts, and jacking piece is connected with stair bottom embedded sleeve barrel with the bolt of M16；
Step 3, the lifting of precast stair plate are in place；
Step 3.1, treat that staircase boards are lifted to 500mm in the scope of operation and slightly pause and slowly adjust staircase boards attitude, in place；
After step 3.2 staircase boards coarse positioning, it is finely adjusted according to control line, corrected, it is ensured that the stair sliding seam for having 30mm and cast-in-place structural between suitable for reading；
After step 3.3, staristep correction are finished, mouth horizontal reinforcement under bench and landing slab are reserved horizontal bar splicing colligation, qualified by inspection after, carry out last layer concrete placings.
The installation method of this precast stair is simply effective, and which can improve the installation effectiveness of precast stair in the case where the installation quality of precast stair is guaranteed.
Description of the drawings
Scheme of installations one of the Fig. 1 for precast stair.
Scheme of installations two of the Fig. 2 for precast stair.
Structural representations of the Fig. 3 for supporting construction.
Specific embodiment
The present invention is further illustrated below by way of specific embodiment.
As shown in Figure 1, Figure 2 and Figure 3, a kind of installation method of assembled architecture precast stair；It is characterized in that：Comprise the steps：
Step 1, installation prepare；
Step 1.1, it is familiar with construction drawing, checks verification component numbering, determine installation site, and lifting sequence is numbered；
Step 1.2, as shown in Figure 1 and Figure 2, ejects stair according to construction drawing and installs control line, control line and absolute altitude are checked；Wherein, the reserved 20mm spaces of stair side identity distance structure wall, are the coat of plaster headspace of follow-up just dress；According to the reserved 100mm spaces of banister installation requirement between bench；
Step 1.3, staristep upper and lower opening ladder Liang Niutuichu with C30 pea gravel concretens seat starch；
Pre-buried to general hanger and staircase boards lifting inner nut is connected with bolt, checks shackle snap ring before lifting, can continue slow lifting after confirming firmly by the hoisting prefabricated staircase boards of step 1.4, level；
Step 2, stair bottom support system are installed；
As shown in figure 3, when precast stair is lifted, the bracket concrete intensity of stair is also not up to design requirement, need to make temporary support in stair bottom installation support system；Temporary support is set up using steel pipe scaffold, and rod end arranges top bracketing, and top bracketing is connected with jacking piece with 4 M12 bolts, and jacking piece is connected with stair bottom embedded sleeve barrel with the bolt of M16；
Step 3, the lifting of precast stair plate are in place；
Step 3.1, treat that staircase boards are lifted to 500mm in the scope of operation and slightly pause and slowly adjust staircase boards attitude, in place；
After step 3.2 staircase boards coarse positioning, it is finely adjusted according to control line, corrected, it is ensured that the stair sliding seam for having 30mm and cast-in-place structural between suitable for reading；
After step 3.3, staristep correction are finished, mouth horizontal reinforcement under bench and landing slab are reserved horizontal bar splicing colligation, qualified by inspection after, carry out last layer concrete placings.
The installation method of this precast stair is simply effective, and which can improve the installation effectiveness of precast stair in the case where the installation quality of precast stair is guaranteed.
