High-rise building elevator well safety device
Technical Field
The utility model relates to a building device, in particular to a high-rise building elevator shaft safety protection device.
Background
Safety construction is the top of the heavy load of building construction all the time, in current protection, the protection of building outside has been accomplished comparatively perfectly, but to inside the building, especially the horizontal high altitude protection of elevator shaft hole, usually carelessness leads to the fact the accident height to send out, current elevator shaft hole protection is mostly direct to the split bolt on the shaft hole lateral wall, single point ligature safety net on the bolt, when the heavy object in high altitude falls to the safety net, the safety net easily pulls off or the damage, protective properties is relatively poor.
Disclosure of Invention
The utility model provides a high-rise building elevator shaft safety protection device which is simple in structure and good in protection performance.
The technical scheme adopted by the utility model is as follows: the utility model provides a high-rise building elevator well safety device which characterized in that: the device comprises a left protective mesh plate and a right protective mesh plate, wherein the left protective mesh plate and the right protective mesh plate are symmetrically and horizontally arranged in a hoistway according to the center of a door opening of a floor of the elevator hoistway, the lower parts of the left protective mesh plate and the right protective mesh plate are hinged through a plurality of one-way hinges, the top angles of one sides of the left protective mesh plate and the right protective mesh plate far away from the door opening are correspondingly connected to a steel pipe column of a door opening pouring support mold through steel wire ropes respectively, and the sides of the left protective mesh plate and the right protective mesh plate close to the door opening are correspondingly connected to the steel pipe column of the door opening pouring support mold through steel wire ropes respectively; the non-hinged outer side edges of the left and right protective mesh plates are directly connected with side limiting steel plates towards the lower direction.
Furthermore, the left and right protective mesh plates are formed by interweaving phi 10@300X300 bidirectional steel bars.
Further, steel wire rope nets are covered under the left and right protective mesh plates.
Furthermore, the upper part of the steel pipe column is locked with an upper pulling connection seat through a bolt, and the upper pulling connection seat is connected with the left or right protective mesh plate through a steel wire rope in a pulling way.
Further, the hinge plate of the one-way hinge is arranged on the upper portion, and the hinge shaft of the one-way hinge is arranged on the lower portion.
According to the utility model, the left and right protective mesh plates are arranged in the hoistway, are hinged by the limited one-way hinge and can only be folded upwards in a rotating manner, so that the protective mesh plates can be prevented from being folded due to the impact of falling objects from high altitude while convenient folding and unfolding are realized, the falling objects can be prevented from continuously falling, and the left and right protective mesh plates are pulled and connected by the steel wire ropes for reinforcement.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a view a-a of fig. 1.
In the figure: the elevator shaft comprises a shaft 1, an elevator shaft floor opening door 2, a steel pipe column 3, an upper pulling connection seat 4, a lower pulling connection seat 5, a left protective mesh plate 6, a right protective mesh plate 7, a one-way hinge 8, a steel wire rope 9, a steel wire rope net 10 and a side limiting steel plate 11.
Detailed Description
The following further description is made in conjunction with the accompanying drawings and examples.
Shown in FIGS. 1 and 2: a high-rise building elevator well safety protection device comprises an upper pull connecting seat 4, a lower pull connecting seat 5, a left protective mesh plate 6, a right protective mesh plate 7, a one-way hinge 8, a steel wire rope 9, a steel wire rope net 10 and a side limit steel plate 11. The left and right protective mesh plates 6 and 7 are arranged in the hoistway in a centrosymmetric manner and horizontally at the elevator hoistway floor opening 2, the lower parts of the left and right protective mesh plates are hinged through a plurality of one-way hinges 8, and steel wire rope nets 10 are covered below the left and right protective mesh plates; the top angles of one sides of the left and right protective mesh plates far away from the doorway are correspondingly connected with an upper pull connection seat 4 on a steel pipe column 3 of the doorway pouring support formwork through steel wire ropes 9 respectively, and one sides of the left and right protective mesh plates close to the doorway are correspondingly connected with a lower pull connection seat 5 on the steel pipe column 3 of the doorway pouring support formwork through steel wire ropes respectively; the non-hinged outer side edges of the left and right protective mesh plates are directly connected with the side limiting steel plates 11 downwards.
In this embodiment, the left and right guard net plates are made of phi 10@300X300 bidirectional steel bars by interweaving.
In this embodiment, it is preferred that the hinge plate of the one-way hinge is on top and the hinge axis is on bottom.
