Detailed description of the invention
Fig. 1 is a kind of elevator shaft horizontal safety protector.Form primarily of 2 diagonal braces 4.Diagonal brace is strip, and its length is greater than the spacing of shear wall before and after elevator hoistways, and is inclined in before and after elevator hoistways between shear wall with rear end higher than the mode of front end, and the angle of the horizontal plane of diagonal brace and elevator hoistways is 15 degree.Diagonal brace rear and front end is connected with front temple 6 and rear temple 5 respectively by bolt, and the front end of diagonal brace is also fixed with the bayonet socket 8 that stretches out hoistway shear wall, and bayonet socket 8 is just in time stuck in floor 2 edge (Fig. 2) at elevator door 3 place.
Front temple 6 and rear temple 5 for suitably increasing the contact area at diagonal brace two ends and shear wall, prevent diagonal brace two ends stressed larger time insert in shear wall.
Bayonet socket 8 for blocking the floor 2 at elevator doorway place, thus makes diagonal brace can be stuck in not landing downwards in elevator hoistways.
The front-end and back-end of diagonal brace are provided with connecting hole 10.The front-end and back-end of 2 diagonal braces respectively adopt a U-shaped pull bar 9 through connection through hole to carry out hinged.The connecting hole (Fig. 3) be positioned on two diagonal braces 4 is caught at the two ends of every root pull bar 9.
Diagonal brace 4 is provided with block 7 along length by the spacing of setting above, glides for the overburden blocked above diagonal brace.
As shown in Figure 4, for elevator hoistways inner chamber is all covered, on diagonal brace, also press block spacing laterally lay flitch 11, waste and old plank or the template 12 by mistake is laid above flitch, plank or template just in time can hide the inner chamber plane of elevator hoistways, if like this top have the article that drop even constructor will be blocked or hold.
