Greatly, the assistant conveyance amount of mine is increased.
For above situation, those skilled in the relevant art develop various quick vertical mold devices.Such as the closed engineering in part
It is middle to cooperate steel mesh formwork erection, this device quick construction using hydraulic prop, but closed rear inboard monomer cannot recycle, and mention
High closed cost.
Utility model content
The technical problems to be solved in the utility model is to overcome the above technological deficiency, quick formwork erection when providing a kind of closed,
Closed cost is reduced, a kind of quick vertical mold device of fire dam of the closed efficiency in tunnel is improved.
In order to solve the above technical problems, technical solution provided by the utility model are as follows: a kind of quick vertical mold device of fire dam,
Including fire dam wall, the quick vertical mold device is made of vertical bar, horizon bar, oblique rod, the vertical bar, horizon bar,
It is mutually connected by the way of hinged between oblique rod, the vertical bar is disposed vertically on the bottom plate of fire dam wall, horizontal
Bar is fixed on the bottom plate of fire dam wall, and oblique rod passes through flexible encapsulated bag and connect composition tripod with horizon bar and vertical bar
Structure is placed with steel mesh between the vertical bar and flexible encapsulated bag.
Preferably, the quick vertical mold device is tripod structure.
Preferably, which is made of the vertical bar that is hinged, horizon bar, oblique rod.
Preferably, the vertical bar, horizon bar, oblique rod length be 1.5m-2.0m.
The utility model compared with prior art the advantages of be:
1, quick formwork erection guarantees that surface of wall flatness meets the requirements；
2, it solves the problems, such as that fire dam inboard formwork erection monomer is unrenewable, reduces closed cost；
3, the closed efficiency in tunnel is improved, it is easy to spread.

In figure: 1 fire dam wall, 2 flexible encapsulated bags, 3 steel meshes, 4 vertical bars, 5 horizon bars, 6 oblique rods.
Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings.
Embodiment
Referring to Fig.1-4, the quick vertical mold device of a kind of fire dam, including fire dam wall 1, the quick vertical mold device is by erecting
It is formed to bar 4, horizon bar 5, oblique rod 6, the vertical bar 4, horizon bar 5 are mutually connected by the way of hinged between oblique rod 6
It connecing, the vertical bar 4 is disposed vertically on the bottom plate of fire dam wall 1, and horizon bar 5 is fixed on the bottom plate of fire dam wall 1,
Oblique rod 6 passes through flexible encapsulated bag 2 and connect composition tripod structure, the vertical bar 4 and flexibility with horizon bar 5 and vertical bar 6
Steel mesh 3 is placed between closed bag 2.
In the present embodiment, the specification of fire dam wall 1 is set as width 4000mm × high 3000mm × thickness 1500mm.
1. processing the vertical bar 4 of long 3000mm, long 1500mm using the steel pipe of 50 × 5mm of φ according to drift section size
Oblique rod 6 each 6 of horizon bar 5, long 3350mm, and bolt will be used hinged between vertical bar 4, horizon bar 5 and oblique rod 6.
5000mm × 3600mm × 1800mm flexible encapsulated bag 2 is processed using air duct coated cloth, closed bag 2 closed abundant to guarantee
In wall height and width direction, there are surplus capacities；
2. the side topmast shield in 1 thickness range of tunnel fire dam wall is wiped out and each slotting 200-300mm；
3. as shown in Figure 1, Figure 2, Fig. 3, arranges 3 supporting points, using 6 frame tripods, each 2 frame tripod of supporting point, and 3 branch
