It was found that cover board body stability of strutting system is poor, cause its use reliability poor, and after cover board body placement, in inspection shaft
Portion's observation maintenance is more inconvenient, poor so as to cause the practicality.
Utility model content
In order to solve the above technical problems, the utility model, which provides one kind, can be improved its cover board body stability of strutting system, mention
Its high use reliability, and after cover board body placement, observation maintenance is more convenient inside inspection shaft, to improve the practicality
Double triangle cover plate of manhole.
A kind of double triangle cover plate of manhole of the utility model, including cover board body；Cover board body includes two groups of right-angle sides
The right angled triangle scoreboard all the same with bevel edge, two groups of shorter sides of scoreboard right-angle side are provided with installation sheet group, two components
The side of plate bevel edge is provided with threaded mounting hole.
A kind of double triangle cover plate of manhole of the utility model, a side bottom of two groups of scoreboard bevel edges are provided with reinforcing rib
Plate.
A kind of double triangle cover plate of manhole of the utility model is provided with and communicated with communication port in two groups of scoreboards.
A kind of double triangle cover plate of manhole of the utility model, two groups of a length of 750mm in the shorter side of scoreboard right-angle side, two
The group a length of 780mm in the longer side of scoreboard right-angle side.
Compared with prior art the utility model has the following beneficial effects: one piece of integral panels of existing Cover Plate Body Is, and
The mode of the two groups of scoreboards geometrical principle most firm according to triangle supported at three point, two groups of scoreboards are at the limiting slot on inspection shaft top
Reach steady placement, and two groups of scoreboards are mounted at limiting slot using shaft connection, two groups of scoreboards pass through screw and two groups of spiral shells
The cooperation of line mounting hole is attached, and has a certain range of changing of the relative positions gap, so that two groups of scoreboards be made to keep independence, can both be mentioned
After its high cover board body stability of strutting system improves its use reliability, and cover board body is placed, screw is back-outed, right angle is prolonged
Two groups of scoreboards of short side side to overturn, inspection shaft inside is that observable maintenance is more convenient, to improve the practicality.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram that two groups of scoreboards are connect with installation sheet group；
It is attached marked in the figure: 1, scoreboard；2, installation sheet group；3, threaded mounting hole；4, stiffener plate；5, communication port.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
As depicted in figs. 1 and 2, a kind of double triangle cover plate of manhole of the utility model, including cover board body；Cover board body
Including two groups of right-angle sides and bevel edge right angled triangle scoreboard 1 all the same, two groups of shorter sides of scoreboard right-angle side are provided with
Installation sheet group 2, the side of two groups of scoreboard bevel edges are provided with threaded mounting hole 3；One piece of integral panels of existing Cover Plate Body Is,
And the geometrical principle that the mode of two groups of scoreboards is most firm according to triangle supported at three point, limiting slot of two groups of scoreboards on inspection shaft top
Place reaches steady placement, and two groups of scoreboards are mounted at limiting slot using shaft connection, and two groups of scoreboards pass through screw and two groups
The cooperation of threaded mounting hole is attached, and has a certain range of changing of the relative positions gap, both can be with so that two groups of scoreboards be made to keep independence
Its cover board body stability of strutting system is improved, its use reliability is improved, and after cover board body placement, screw is back-outed, is prolonged straight
Two groups of scoreboards of angle short side side to overturn, inspection shaft inside is that observable maintenance is more convenient, to improve the practicality.
A kind of double triangle cover plate of manhole of the utility model, a side bottom of two groups of scoreboard bevel edges are provided with stiffener plate
