Description
Technical field
This utility model belongs to construction safety field, is specifically related to one and faces hole, limit action shield.
Background technology
At the scene in work progress, in order to ensure construction safety, face hole, limit everywhere and be required for protecting with steel pipe or barrier.Commonly used mode of going along with sb. to guard him is installation iron plate on the floor faced at hole, limit or body of wall, fixes with setscrew.Welded still pipe sleeve pipe on steel plate, with fixed protection railing.Work progress needs hole on concrete wall, floor, also need after having constructed to excise setscrew, metope is repaired, time-consuming takes a lot of work.And when facing wall plastering or the construction of other working procedure at hole, limit, need to remove preventer, need after having constructed again to recover hole protection, increase construction cost.During facing hole, limit wall construction, the preventer of dismounting recovered as do not removed the same day same day, and security incident easily occurs in unprotected hole, limit of facing.Accordingly, it would be desirable to a kind of ease of assembly dismounting and reusable edible face limit opening protective device.
Utility model content
The problem existed for prior art, this utility model is that the technical scheme that solution problems of the prior art use is as follows:
nullOne faces hole, limit action shield，Including the pre-pre-buried vertical rod 4 being embedded in hole marginal center and two horizontal cross bars 3 up and down being perpendicular to pre-buried vertical rod 4 installation，Described horizontal cross bar 3 is respectively arranged at the two ends with an activity vertical rod 8，Described pre-buried vertical rod 4 is pre-buried is positioned parallel to the most pre-buried one section of embedded steel tube 7 in entrance orientations both sides，Described embedded steel tube 7 arrives the horizontal range between pre-buried vertical rod 4 and activity vertical rod 8 is identical to the horizontal range between pre-buried vertical rod 4，In the general frame that each cross bar and vertical rod are formed, Dense mesh screen 6 is installed，Described activity vertical rod 8 is inserted 90 ° of hooked bars 1，After in 90 ° of hooked bar 1 fully-inserted activity vertical rods 8，Activity vertical rod 8 partial-length is protruded from identical with the length of embedded steel tube 7 bottom 90 ° of described hooked bars 1，90 ° of described hooked bar 1 top hook portion fit in the upper surface of activity vertical rod 8，90 ° of described hooked bars 1 can be mentioned in activity vertical rod 8 and put down.
All it is connected by cross steel tube clamps 5 between described pre-buried vertical rod 4 with horizontal cross bar 3 and horizontal cross bar 3 with activity vertical rod 8, easy disassembly, it is achieved the flexible connection of preventer framework.
Described Dense mesh screen 6 is bound with horizontal cross bar 3, pre-buried vertical rod 4 and activity vertical rod 8 by iron wire 2 so that assembling and disassembling is convenient and swift.
Described horizontal cross bar 3, pre-buried vertical rod 4 and activity vertical rod 8 are thickness 3mm, and the steel pipe of external diameter 48mm is made, and make overall structure stable and light.
The pre-buried a length of 50mm of described embedded steel tube 7, inserts fixing for 90 ° of hooked bars 1.
This utility model has the advantage that
This utility model uses steel pipe to form preventer general frame with fastener, and with intermediate uprights for supporting, two ends bolt-type reinforcing bar is fixed, and passes through said structure so that overall structure is firm, it is simple to realize；Can be with construction working task, with intermediate uprights as fulcrum, rotate preventer, meet construction requirement；Easy accessibility during this utility model application, the most repeatable utilization of each assembly, reduces construction cost, accelerating construction progress.

Detailed description of the invention
nullBelow by embodiment，And combine accompanying drawing，The technical solution of the utility model is described in further detail，As shown in Figure 1-2，One faces hole, limit protection head，Including the pre-pre-buried vertical rod 4 being embedded in hole marginal center and two horizontal cross bars 3 up and down being perpendicular to pre-buried vertical rod 4 installation，Described horizontal cross bar 3 is respectively arranged at the two ends with an activity vertical rod 8，The pre-buried entrance orientations both sides that are positioned parallel to of described pre-buried vertical rod 4 are each perpendicular to the embedded steel tube 7 that the pre-buried segment length in ground is 50mm，Described embedded steel tube 7 arrives the horizontal range between pre-buried vertical rod 4 and activity vertical rod 8 is identical to the horizontal range between pre-buried vertical rod 4，Dense mesh screen 6 is installed in general frame，Described activity vertical rod 8 is inserted 90 ° of hooked bars 1，After in 90 ° of hooked bar 1 fully-inserted activity vertical rods 8，Activity vertical rod 8 partial-length is protruded from identical with the length of embedded steel tube 7 bottom 90 ° of described hooked bars 1，90 ° of described hooked bar 1 top hook portion fit in the upper surface of activity vertical rod 8，90 ° of described hooked bars 1 can be mentioned in activity vertical rod 8 and put down.
All it is connected by cross steel tube clamps 5 between described pre-buried vertical rod 4 with horizontal cross bar 3 and horizontal cross bar 3 with activity vertical rod 8.
Described Dense mesh screen 6 is bound with horizontal cross bar 3, pre-buried vertical rod 4 and activity vertical rod 8 by iron wire 2.
Described horizontal cross bar 3, pre-buried vertical rod 4 and activity vertical rod 8 are thickness 3mm, and the steel pipe of external diameter 48mm is made.
This utility model in use, is supported by middle pre-buried vertical rod 4, and two ends 90 ° of hooked bars of bolt-type 1 are fixed so that it is firm that this faces hole, limit action shield general safety.When facing hole, limit both sides body of wall or the construction of hole outside need, overall preventer need not be removed, only 90 ° of preventer two ends hooked bar 1 need to be extracted out, in the middle of connecting, the cross steel tube clamps 5 of pre-buried vertical rod 4 and horizontal cross bar 3 unclamps, centered by middle pre-buried vertical rod 4, unitary rotation preventer, then cross steel tube clamps 5 is tightened；As preventer need to be recovered, only middle cross steel tube clamps 5 need to be unclamped, preventer be gone back to initial position, fixes and can recover former state.
Protection domain of the present utility model is not limited to the above embodiments, it is clear that those skilled in the art can carry out various change and deformation without deviating from scope and spirit of the present utility model to this utility model.If these are changed and deformation belongs in the range of this utility model claim and equivalent technologies thereof, intention the most of the present utility model also comprises these and changes and deformation.
