At present, with the continuous development of China's economy, the construction of road is the premise guarantee of economic development, in road construction
During, tunnel construction is inevitable construction link, and in tunnel construction, the construction of Central drain is particularly important, in
Edema with the heart involved ditch is completed generally by formwork for placing, and Central drain formwork for placing is all split-type structural, and splicing completion pours, and
Traditional Central drain formwork for placing is fixed structure, it is impossible to pours various sizes of Central drain, uses cumbersome.
Utility model content
It in order to solve to exist in the prior art Central drain formwork for placing is fixed structure that the purpose of this utility model, which is, is poured
Build the shortcomings that Central drain size is single, and a kind of tunnel Central drain formwork for placing proposed.
To achieve these goals, the utility model employs following technical scheme：
Design a kind of tunnel Central drain formwork for placing, including bed die, the first side form and the second side form, first side form
It is rotatably connected on respectively on the bed die both sides with the second side form, uniform welding has some three along its length on the bed die
Angle support, some A-frame tops are welded with contiguous block, and the both sides of the contiguous block are equipped with the first journal stirrup, described
The first screw mandrel is rotatably connected on first journal stirrup, the one end of first screw mandrel away from first journal stirrup is threaded with
Regulation pipe, the regulation pipe are female thread structure；The inner side of first side form and the second side form corresponds to the A-frame
Position is equipped with some second journal stirrups, and the second screw mandrel is rotatably connected on some second journal stirrups, and second screw mandrel is remote
Threaded one end from second journal stirrup is connected in the regulation pipe.
Preferably, the contiguous block is welded with hanger.
Preferably, the both ends of the bed die, the first side form and the second side form are equipped with pad, and the pad is rubber blanket,
And it is hollow-core construction.
Preferably, it is welded with connection sheet on the inside of the both ends of first side form and the second side form, in the connection sheet
Offer connecting hole.
The utility model proposes a kind of tunnel Central drain formwork for placing, beneficial effect is：In the utility model
Two rotatable sides are touched adjusts subtended angle size by adjusting pipe, effectively adjusts out the Central drain that section is different structure, makes it
Central drain formwork for placing can adjust out the Central drain stay in place form of needs according to tunnel construction field requirement, simple in construction,
Adjust efficient and convenient, strong applicability.
Brief description of the drawings
Fig. 1 be the utility model proposes a kind of tunnel Central drain formwork for placing structural representation；
Fig. 2 be the utility model proposes a kind of tunnel Central drain formwork for placing overlooking the structure diagram.
In figure：Bed die 1, the first side form 2, the second side form 3, A-frame 4, contiguous block 5, hanger 6, the first screw mandrel 7, regulation
Pipe 8, the second screw mandrel 9, the first journal stirrup 10, pad 11, the second journal stirrup 12, connection sheet 13.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.
Reference picture 1-2, a kind of tunnel Central drain formwork for placing, including bed die 1, the first side form 2 and the second side form 3, the
One side form 2 and the second side form 3 are rotatably connected on the both sides of bed die 1 respectively, the rotation connection of the first side form 2 and the second side form 3, tunnel
Road edema with the heart involved ditch formwork for placing can be by adjusting the first side form 2 and the subtended angle size of the second side form 3 and bed die 1, to obtain in difference
The sectional dimension of edema with the heart involved ditch, make its applicability stronger, uniform welding has some A-frames 4 along its length on bed die 1, if
The dry top of A-frame 4 is welded with contiguous block 5, and contiguous block 5 is welded with hanger 6, and the structure of A-frame 4 is more stable,
The active force that it bears is stronger, hanging when hanger 6 is easy for installation and removal.
The both sides of contiguous block 5 are equipped with the first journal stirrup 10, are rotatably connected to the first screw mandrel 7 on the first journal stirrup 10, and first
The one end of screw mandrel 7 away from the first journal stirrup 10 is threaded with regulation pipe 8, and regulation pipe 8 is female thread structure, the He of the first side form 2
The position that the inner side of second side form 3 corresponds to A-frame 4 is equipped with some second journal stirrups 12, is rotated on some second journal stirrups 12
The second screw mandrel 9 is connected with, threaded one end of second screw mandrel 9 away from the second journal stirrup 12 is connected in regulation pipe 8, and regulation pipe 8 is realized
The adjustment of first side form 2 and the subtended angle size of the second side form 3, different directions rotation regulating pipe 8 are located at the inside of regulation pipe 8 the
