Description
Technical field
The invention belongs to end temporary steel support support replacement technical field of standing, and in particular to a kind of station end temporary steel support support replacement
Construction method.
Background technology
When closing on the in-situ beam casting at station, station structure has to construction to station hall layer, and station end is used to support cast-in-place
The bracket of beam is located above station hall layer, is missed the stop needs according to beam car, in the case where bracket is not constructed, Cast-in-situ Beam is temporarily used
Arrangement form holds up beam body for the bracing members of single nine, after the completion for the treatment of that prefabricated box beam is all transported and set up, station end
Portion position is constructed bracket component again, on the bracket that then end of continuous beam is fallen within to station stretching.
The stabilization of beam body stress when passing through temporary steel support in order to ensure beam car, and beam body end during construction in later period bracket
There can be reliable and stable temporary support, the arrangement form of single nine bracing members is changed to double 10, but lack at present
The construction method of few bracing members support replacement, it is impossible to complete more reliable and more stable bracing members.
The content of the invention
In view of this, it is a primary object of the present invention to provide a kind of construction method of station end temporary steel support support replacement.
To reach above-mentioned purpose, the technical proposal of the invention is realized in this way：
The embodiment of the present invention provides a kind of construction method of station end temporary steel support support replacement, and this method is real by following steps
It is existing：
Step one：In the side for bearing the first support system of cast-in-situ continuous beam weight, the second support system is set；
Step 2：Cast-in-situ continuous beam is propped up by the jack on the first support system, then in the described second support
Temporary support is set in system, and places the space that steel plate is used to fill up between temporary support and cast-in-situ continuous beam, now, slowly
It is slow to fall beam body after rise so that the load-bearing of the cast-in-situ continuous beam is located on second support system, complete first time bearing system
Conversion；
Step 3：Remove first support system and be excavated to positioned at the cushion cap face of platform drilled pile, afterwards, in institute
State the construction that the 3rd support system is carried out on cushion cap face；
Step 4：After 3rd support system construction is finished, shored by very heavy on the 3rd support system
Play cast-in-situ continuous beam, then bearing be set on the 3rd support system, and place steel plate be used to filling up bearing with it is cast-in-place
Space between continuous beam, now, slowly falls beam body after rise so that the load-bearing of the cast-in-situ continuous beam is located at the 3rd supporter
Fasten, complete second of bearing system conversion；
Step 5：Remove second support system.
In such scheme, first support system is nine steel support structures of single setting.
In such scheme, second support system is 2 steel support structures of single setting and reinforces diagonal brace.
In such scheme, the 3rd support system is ten steel support structures of double setting.
In such scheme, 2 steel support structures of second support system are arranged on original ground and extended to
40 meters of underground.
In such scheme, the jack is four groups of 200t jack, is laid in apart from the beam bottom both sides of cast-in-situ continuous beam
In edge 20cm.
In such scheme, the cast-in-situ continuous beam is less than or equal to 1cm by jack stand, while static observation beam body is heavy
Drop data, is determined after situation without exception, then place steel plate be used to filling up temporary support or bearing and cast-in-situ continuous beam it
Between space and slowly fall beam body after rise.
Compared with prior art, beneficial effects of the present invention：
The present invention is able to ensure that the two times transfer of stress during bracing members support replacement, it is ensured that the security of support replacement process, enters
And ensure the reliable and stable of the station end after changing into.
