Description

Elevator shaft protective guard on building site
Technical field
The utility model belongs to building site protective equipment technical field, especially relates to the elevator shaft protective guard on a kind of building site.
Background technology
At present, in the construction of building site, the protection of elevator shaft reserved opening is the pith of site safety facility.Existing elevator shaft guardrail is normally gathered materials on the spot, easy guardrail is built in order to shelter from the doorway of elevator shaft with sheet material or scaffolding steel pipe and fastener, but, because it is not combined securely with elevator shaft hole, in use bear incessantly larger impact, easily like this cause potential safety hazard; Although also have some protective guards be fixed with bolt now, the protective guard of this structure is installed and dismounting is comparatively wasted time and energy, and also needs after removal to repair ground threaded bore portion, uses comparatively inconvenience; Therefore be necessary to be improved.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, provides the protective guard of the elevator shaft on a kind of building site, and it has simple, the easy to use and safety preferably feature of structure.
To achieve these goals, the technical scheme that the utility model adopts is: the elevator shaft protective guard on a kind of building site, comprises base, column and cross bar, and described column is fixedly installed on base, and the two ends of described cross bar are separately positioned on column; The both ends of described cross bar are provided with threaded portion, and described threaded portion is bolted with nut, and the end of described nut abuts with the outer face of column; Described base is provided with card base, and the top of described column is provided with clamping block.
Described cross bar is provided with locknut, and described locknut abuts with the medial surface of column and arranges.
Described cross bar is coated with fluorescent belt.
Described column is coated with fluorescent belt.
Spacing between described cross bar is upper and lower is 30 ~ 40cm.
Adopt after said structure, the utility model compared to the prior art advantageously: structure of the present utility model is simple, and fixed by nut on column by cross bar sleeve, this structure makes installation connect dismounting all more for convenience; And the card base on base and the clamping block on column in use can carry out clamping with body of wall, make fixing better, prevent the generation of contingency.

Fig. 2 is understructure schematic diagram of the present utility model.
Fig. 3 is bar structure schematic diagram of the present utility model.
Fig. 4 is clamping block structural representation of the present utility model.
Detailed description of the invention
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model, further illustrates below in conjunction with drawings and Examples to the utility model.
Embodiment, is shown in shown in Fig. 1 to Fig. 4: the elevator shaft protective guard on a kind of building site, comprises base 10, column 20 and cross bar 30; Base 10 offers spliced eye 12, the lower end of column 20 is fixedly plugged in spliced eye 12.Column 20 offers through hole, and sleeve is on the through hole of correspondence respectively at the both ends of cross bar 30, and the spacing between upper and lower two cross bars 30 is 30 ~ 40cm, selects 35cm to be good in the ordinary course of things.The both ends of cross bar 30 are provided with threaded portion 31, threaded portion 31 are bolted with nut 32, and the inner face of nut 32 abuts with the outer face of column 20; Threaded portion 31 is also bolted with locknut 33, and locknut 33 is positioned on the cross bar 30 of top and bottom, and locknut 33 abuts with the medial surface of column 20; This vibrational power flow can allow to be installed and dismantles all very convenient, and can prevent cross bar 30 and column 20 from occurring to loosen phenomenon by nut 32 and the locking of locknut 33.Base 10 also has card base 11, at the top of column 20, there is clamping block 21, be formed with step 13 between card base 11 and base 10, and clamping block 21 have card column 211 and draw-in groove 212; Card column 211 can with the blocked hole snap-fit engagement at column 20 top, and step 13 and draw-in groove 212 in use all can carry out clamping setting with body of wall, effectively can improve fixing like this, prevent the generation of contingency.Cross bar 30 and column 20 all on be coated with fluorescent belt 40, fluorescent belt 40 can emit beam under dim environment, can play good warning function.
