The present invention also proposes a kind of construction method of transfer station across original coal transporting trestle, includes the following steps:
It is poured at frame column 100 to 500 top surface elevation location of supporting element；
It lifts fixed precast concrete Vierendeel girder: being fixedly connected with prefabricated frame between 2 opposite frame columns 100 and set a roof beam in place 200,
And make prefabricated frame 200 both ends of setting a roof beam in place fixed with supporting element 500 respectively；
It sets a roof beam in place 200 installation steel secondary beams 300 in prefabricated frame, profiled sheet counterdie 600 is laid on steel secondary beam 300；
It transfers 400 reinforcing bar of floor and arrives steel plate die mould counterdie, so that 400 reinforcing bar of floor extends to prefabricated frame and sets a roof beam in place 200, extension
Length guarantees enough anchorage lengths by construction code requirement；
Pouring molding floor 400 and frame column 100 positioned at 500 above section of supporting element.Specifically, 100 He of frame column
Supporting element 500 is preferably integrally formed part, and supporting element 500 selects bracket in the present embodiment, bracket be located at 100 side of frame column and
At 100 bottom certain altitude position of frame column, when being constructed, first the part of frame column 100 is poured, i.e.,
Concrete casting is only constructed to bracket top side location, wherein in bracket side pre-buried first connector 510 such as steel plate.?
Construct frame column 100 while or in the early time, first make prefabricated frame and set a roof beam in place 200 and steel secondary beam 300, wherein set a roof beam in place in prefabricated frame
200 side also arranges the second connector 210 such as steel plate embedded part or steel corbel in advance, prefabricated frame set a roof beam in place 200 both ends bottom
The pre-buried third connector 220 in face such as steel plate embedded part, and shearing resistance slot 230 is set in end.
After 100 concrete strength of frame column of part to be cast reaches intensity requirement, arrange lifting equipment lifting prefabricated
Vierendeel girder 200 rides upon 500 top surface of supporting element, is then connected again using the 4th connector 700 with the first of 500 side of supporting element
The set a roof beam in place third connector 220 of 200 end sides of fitting 510 and prefabricated frame welds, and sets a roof beam in place 200 to fix prefabricated frame.Then
It recycles the second connector 210 arranged in advance such as steel plate embedded part or steel corbel that fixed steel secondary beam 300 is installed, is laid with later
Profiled sheet counterdie 600, decentralization binding floor bar 800；Finally again to it is more than bracket 100 part of frame column and floor 400,
Prefabricated frame set a roof beam in place 200 and steel secondary beam 300 carry out second of concrete casting so that all component disposal pourings form, complete
Transfer station across original coal transporting trestle is constructed.
Transhipment station structure in the present embodiment is located at 500 or less supporting element by being first poured frame column 100 in construction
Part, based on support, the support to entire transfer station is then realized by frame column 100 in this way, without setting up full hall
Then scaffold is mounted directly prefabricated profiled prefabricated frame on frame column 100 and sets a roof beam in place 200 and steel secondary beam 300, then in steel
It is laid with profiled sheet counterdie 600 on beam 300, carries out molding and frame column that second pouring realizes floor 400 and frame column 100
100 and floor 400, prefabricated frame set a roof beam in place the connection of 200 and steel secondary beam 300, phase is assembled using pouring technology twice and existing beam column
In conjunction with without setting up scaffold, construction is more convenient.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than is limited；Although referring to aforementioned reality
Applying example, invention is explained in detail, for those of ordinary skill in the art, still can be to aforementioned implementation
Technical solution documented by example is modified or equivalent replacement of some of the technical features；And these are modified or replace
It changes, the spirit and scope for claimed technical solution of the invention that it does not separate the essence of the corresponding technical solution.
