Bar penetrates the connecting hole of a protective plate and passes through the nut check of the bolt, and the screw rod of another bolt of the connection lock is worn
Enter the connecting hole of another protective plate and several piece protective cover plate is combined by the nut check of the bolt.
In a preferred embodiment, handle is fixed in the middle part of protective plate.
In a preferred embodiment, handle is bridge shape.
In a preferred embodiment, the bottom plate for connecting lock is rectangle.
Compared with prior art, the utility model has the following beneficial effects:
1, it is fixed on horizontal hole using stationary fixture, it is easy to operate, it is not easy to be inadvertently move and protection is caused to fail.
2, fixing clamp is not influenced by slab thickness when fixed, and the horizontal hole of various thickness floors is suitble to protect.
3, fixing clamp can move in a certain range, and monolithic protective cover plate is allowed to be suitble to various sizes of hole anti-
Shield.Several piece protective cover plate can be combined to meet the protection needs at bigger hole.
4, need a kind of specification that can meet the protection needs at the various horizontal holes in general construction site, only convenient for production and pipe
Reason.
5, the protection at the horizontal hole of some specific positions such as two sides Lin Qiang can be suitble to.
6, connecting hole plays the role of peep hole simultaneously, can lead to cover board side to determine whether cover board has occurred movement
Along excessively close apart from hole edge.
7, it can repeat to be used in turn.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the Combined water adit opening protective cover plate of the utility model.
Fig. 2 is the combining structure schematic diagram of the Combined water adit opening protective cover plate of the utility model.
Fig. 3 is the schematic cross-sectional view in the direction A-A of Fig. 2.
Specific embodiment
With reference to the accompanying drawing, specific embodiment of the present utility model is described in detail, it is to be understood that this is practical
Novel protection scope is not limited by the specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " includes " or its change
Changing such as "comprising" or " including " etc. will be understood to comprise stated element or component, and not exclude other members
Part or other component parts.
As shown in Figure 1, according to the Combined water adit opening protective cover plate of specific embodiment of the present invention using protection
Plate, fixing clamp (containing fixture nut), connection lock, main body of the handle as this protection tool, can work independently, can also be with several piece
It is combined to meet the requirement of shelter at bigger hole.The specific structure of the Combined water adit opening protective cover plate includes: protection
Plate 1, fixing clamp 2, connection lock 3 and handle 4.Wherein, protective plate 1 is fixed on horizontal hole using fixing clamp 2, easy to operate,
It is not easy to be inadvertently move and protection is caused to fail.Fixing clamp is not influenced by slab thickness when fixed, is suitble to various thickness floors
