Description
Technical field
The invention belongs to construction techniques, in particular to a kind of superimposed sheet installs Linear Positioning Accuracy Measurement Methods.
Background technique
With the continuous development of China's economy and the increasingly raising of living standards of the people, infrastructure construction especially building
The construction scale in house is increasing, for plane stiffness, anti-seismic performance and the leakage resistance energy for improving building, existing building
The structural system of object uses cast-in-situ steel reinforced concrete, but this cannot prevent armored concrete by the way of integral cast-in-situ
There is crack on plate, beam or column, it is right although these cracks not exclusively influence the integrally-built stability of building and safety
Consumer will cause the negative effect for worrying safety at cracking, while cast-in-situ reinforced concrete slab is needed since next floor
Build a large amount of brackets, be laid with pour mold, it is time-consuming and laborious, thus trend current in the industry be using superimposed sheet replace cast in place reinforced bar
Concrete slab overcomes aforementioned deficiency.
Superimposed sheet is the building slab that a kind of mode that prefabricated and cast-in-place concrete combines produces, prefabricated board with it is existing thereon
Pouring concrete layer is integrated into a whole superimposed sheet, and the main reinforcement of prefabricated board is the main reinforcement of superimposed sheet, top cast-in-place concrete layer
Negative reinforcement and distributing bar are only configured, prefabricated board is used as the bed die of cast-in-place concrete layer, it is not necessary to be cast-in-place concrete layer branch
Hold mode plate, prefabricated board bottom surface is smooth, and the ceiling (i.e. the bottom surface of superimposed sheet) of lower floor can no longer paint plastering；It is this folded
Plywood has the globality of cast-in-situ reinforced concrete slab, while it is big with rigidity, crack resistance is good, does not increase reinforcing bar consumption, section
About template, shorten the advantages that duration of entire engineering.But superimposed sheet in lifting since it is desired that primary lifting in place, is lifted into
It cannot be moved again behind position, therefore, and existing superimposed sheet is positioned by way of manually estimating.
The Chinese invention application of Publication No. CN106284787A discloses a kind of assembled overlapping board positioning method, including
Following steps:
I, installation positioning stirrup (2) on all frame column reinforcing bars (11) of each floor；
II, by every benchmark control axis (5) pilot measurement of bottom to each floor, and by the position of every axis (5)
It makes marks on the corresponding positioning stirrup (2)；
III, all axis (5) are released, and check the distance between upper every of all frame columns (1) axis (5),
Angle is to meet design requirement；
IV, its two center lines (7) are popped up on having numbered every piece of prefabricated board (3)；
It V, will be every according to the positional relationship of every in the design requirement center line (7) and the corresponding axis (5)
(7) bullet of center line described in item is on corresponding Vierendeel girder (4) side template；
VI, the prefabricated board (3) that reference numeral is installed according to design requirement, makes the center line (7) and frame thereon
The coincidence of the center line (7) snap the line is corresponded on beam (4) side template；
VII, fixed all prefabricated boards (3), the installation for completing prefabricated superimposed sheet are fixed.
Although the positioning of this method has used axis as benchmark, while being compareed using the center line of superimposed sheet, still,
This method is detected there is still a need for artificial using the mode of range estimation, and the error is very big, while artificial range estimation calibration is also deposited
In the disadvantage that calibration speed is slow.
Summary of the invention
It is an object of the invention to: existing error is larger when in place for the aobvious installation of superimposed sheet in the prior art, calibration
Slow-footed problem provides a kind of superimposed sheet installation check method in place.
The technical solution adopted by the invention is as follows:
