Abstract
A kind of construction steel tubing string locating mounting method belongs to subway station digging method construction steel pipe column technical field of construction.Whether steel pipe column positioning accurately determines whether lid excavation construction can be smoothed out.Present invention casting concrete first to locating cone and backing plate (1) below；Locating cone elevation and center are accurately positioned, is bored using Steel bar rack stationary positioned and backing plate (1)；Casting concrete stationary positioned is bored and backing plate (1)；Installation positioner, positioning hole (2) are inserted in locating cone and backing plate (1)；Locator is supported using harness cord bolt (3)；Locator flange respectively installs leveling nut (4) and is used for adjusting locator level up and down；Pour below locator to flange, fixed locator；Installation steel pipe column (6) simultaneously pours；The present invention reduces the construction procedure of conventional steel post construction, and positioning is more accurate, and precision is higher, and speed is faster.
Description
Technical field
The invention belongs to digging method construction steel pipe column technical field of construction, the installation how positioned more particularly to steel pipe column
Method.High construction method is required to steel pipe column positioning construction precision.
Background technology
Digging method construction is commonly used to busy section of town traffic main artery, when obstacles such as underground requirement of engineering highway crossing, buildings
Generally use cap excavation method during thing, to reduce the influence to traffic.It is after one kind is excavated to certain depth downwards by ground, by top
Closing, remaining bottom engineering are constructed under the top cover of closing.Horizontal displacement of its feature to structure is small, safety coefficient
Height, the influence to ground is small, only blocks traffic above-ground in a short time, constructing, it is small to be influenceed by outside climatic.
The support of digging method construction top cover is generally completed by steel pipe column, and steel pipe column often also needs to undertake beam, plate etc.
Structure, this requires that steel pipe column positions and elevation must be accurate, and otherwise beam, plate construction will be impacted.
The content of the invention
In order to solve the above problems, it is an object of the invention to provide a kind of steel pipe column positioning construction method.
In order to achieve the above object,
One kind lid digs station erection of steel pipe column positioning construction method, it is characterised in that comprises the following steps：
1) first casting concrete to locating cone and backing plate (1) below；
2) locating cone elevation and center are accurately positioned, is bored using Steel bar rack stationary positioned and backing plate (1)；
3) casting concrete stationary positioned cone and backing plate (1)；
4) installation positioner (5), positioning hole (2) are inserted in locating cone and backing plate (1)；
5) using harness cord bolt (3) support locator (5)；
6) locator (5) flange respectively installs leveling nut (4) and is used for adjusting locator (5) level up and down；
7) pour below locator (5) to flange, fixed locator (5)；
8) steel pipe column (6) is installed and poured.
Steel pipe column construction method provided by the invention can reduce concreting number, save the concrete curing time,
Faster more accurately positioning steel tube post, ensures the smooth installation in beam slab.
Brief description of the drawings
Fig. 1 is steel pipe column positioning construction method schematic diagram.
Embodiment
Below in conjunction with the accompanying drawings and instantiation the present invention is described in detail.
Now illustrated by taking metro station cover and cut engineering as an example：The station end portion superstructure is busy highway,
To reduce the influence to highway, using digging method construction.After the completion of lid excavation construction, recover road travel, while use contrary sequence method
Work car station agent structure.
Station cover plate supports covering plate structure, agent structure beam, plate etc. to be installed in side wall and steel pipe using 12 steel pipe columns
On post bracket.
The construction method of the present invention includes carrying out the following steps in order：
1) first casting concrete to locating cone and backing plate (1) below；
2) after concrete final set, locating cone and backing plate (1) elevation and center is accurately positioned, is consolidated using Steel bar rack
Determine locating cone and backing plate (1)；
3) casting concrete stationary positioned cone and backing plate (1)；
4) installation positioner (5), positioning hole (2) are inserted in locating cone and backing plate (1)；
5) locator (5) is supported using 3 harness cord bolts (3), bolt branch is stood on concrete surface；
6) locator (5) flange respectively installs leveling nut (4) and is used for adjusting locator (5) level up and down；
7) after measurement and positioning device (5) position, elevation are errorless, pour below locator (5) to flange, fixed locator (5)；
8) steel pipe column (6) is installed and poured；Fine sand, stable steel pipe column are backfilled after the completion of pouring.
Claims (1)
1. a kind of erection of steel pipe column positioning construction method, it is characterised in that comprise the following steps：
1) first casting concrete to locating cone and backing plate (1) below；
