Technical field
The present invention relates to pre-buried steel component in a kind of diaphragm wall or other similar operating mode and carry out the construction method of straightening, especially a kind of construction method of being assisted by mounting limit straightening frame.
Background technology
Along with the development in city, the situation of shortage of land resource is day by day remarkable.The space development utilization rate improving building then becomes the task of top priority.In order to improve the space development utilization rate of building, vertical load node moves in diaphragm wall by increasing structure design, and in continuous underground wall structure, the application of pre-buried steel column also becomes trend of the times.
Because general diaphragm wall reinforcing cage tonnage is large, enter the positioning control of groove depth to integrally wall reinforcing cage and often do not reach respective design permissible accuracy, add cast-in-situ concrete disturbance to the impact of built-in fitting, make such steel column component pre-buried difficulty of construction very large, construction precision is difficult to be guaranteed.Still lack a kind of rationally efficient construction method at present, cause pre-buried steel column constructional difficulties in continuous underground wall structure, waste time and energy, construction effect is not good, steel column off normal is general.
Summary of the invention
The present invention will solve the technical problem that existing underground preburied steel column Embedment Construction precision is low, efficiency of construction low, spillage of material is larger, and provides a kind of underground preburied steel beam column spacing straightening construction method.
For achieving the above object, the present invention is achieved by the following technical solutions:
The spacing straightening construction method of a kind of underground preburied steel beam column, the steps include:
1) vertically-guided cylinder and horizontal adjustment bracket is selected
According to needing the size of pre-buried steel column, form and construction requirement, selected vertically-guided cylinder and horizontal adjustment bracket;
2) steel column is installed guiding and hang muscle
According to construction area absolute altitude and construction requirement, guiding is set at pre-buried steel capital end position and hangs muscle;
3) horizontal adjustment bracket location
Construction area is surveyed, and according to horizontal adjustment bracket size, positioning screw is squeezed on hard place level ground;
4), after wall reinforcing cage is transferred, horizontal adjustment bracket is installed
Ground wall reinforcing cage regulates horizontal girder steel to desired spacing according to construction requirement, screws stop nut 2. after transferring, and after ground wall reinforcing cage is transferred, horizontal adjustment bracket is set on positioning screw;
5) horizontal adjustment bracket leveling
The absolute altitude increasing or reduce on four bases regulates pad, observes the spirit level on vertical, horizontal girder steel, makes horizontal adjustment bracket level, tighten base clamp nut after horizontal adjustment bracket level;
6) vertically-guided cylinder is installed
Vertically-guided cylinder is placed in modulated in the horizontal adjustment bracket of level, inserts limit bolt;
7) steel column is lifted
Steel column is put in vertically-guided cylinder silo, after placing design elevation, fixes steel column on guide cylinder by shoulder pole.
8) diaphragm wall concreting
9) pull down spacing adjusting bracket to recycle
After diaphragm wall concrete initial set, extract vertically-guided cylinder bracket limit bolt out, hang away vertically-guided cylinder, unload lower bottom base clamp nut subsequently, withdraw horizontal adjustment bracket and base.
The invention has the beneficial effects as follows: the sizing adjustable support auxiliary construction of construction method of the present invention owing to selecting, make that constructing operation is easy, efficiency of construction improves, control accuracy promotes, have a extensive future in similar diaphragm wall pre-buried steel column construction operating mode.After transferring ground wall reinforcing cage (or other similar operating modes), utilize the spacing straightening frame of erection to position guiding and straightening to corresponding pre-buried steel beam column, on the one hand, by spacing straightening frame restriction steel column locations, improve construction precision; On the other hand, the features such as regularization straightening frame installation rate is fast, adjustment operation simple, can reuse.Both improve efficiency of construction, again save construction cost.
