Abstract
The utility model discloses an edge protection device for an elevator shaft door on an operation floor in a construction project. The edge protection device comprises a small reinforcing steel bar framework and a large reinforcing steel bar framework, wherein the bottom of the large reinforcing steel bar framework is not sealed, the upper end of the large reinforcing steel bar framework is connected with the lower end of the small reinforcing steel bar framework through a hinge, a limiting triangular steel is arranged at the upper end of the large reinforcing steel bar framework so that the outward rotation angle range of the small reinforcing steel bar framework is from 0 to 270 DEG, a warning placard is fixed at the upper end of the small reinforcing steel bar framework through an iron wire, a plurality of horizontal cross bars are welded inside the large reinforcing steel bar framework, the bottom end of the large reinforcing steel bar framework is vertically inserted into an upright post of an elevator derrick, and a triangular fixing chuck is arranged between the large reinforcing steel bar framework and the upright post of the elevator derrick. The edge protection device disclosed by the utility model is simple to operate, safe, and reliable; according to the edge protection device, the local material can be used, for example, the edge protection device can be obtained by welding the waste and old reinforcing steel bars in the engineering field; and the edge protection is high in availability factor, simple to manufacture, good in integrality, convenient to disassemble, and beautiful in appearance, and can be repeatedly used and used by matching a steel platform of a horizontal protection device for an elevator shaft.
Description
Technical field
The utility model relates to construction site safety protection technique field, relates in particular to a kind of construction work operation layer elevator shaft door place and faces the frontier defense protection unit.
Background technology
Development along with building trade, a lot of buildings need the design elevators, and we are when the operation of constructing operation aspect, and eminence is faced the limit potential safety hazard of falling and existed everywhere, and operation layer elevator shaft door place is the position that security incident is easily sent out, it is one of potential safety hazard relatively more concentrated " four-hole ".At present, operation layer elevator shaft door Lin Bianchu, basically do not do protection or on-the-spot simple enclosing, and, when construction elevator well reinforcing bar, template, have to remove or destroy.Can't reach the purpose of security protection, have a lot of potential safety hazards.
The utility model content
The utility model purpose is exactly in order to make up the defect of prior art, provides a kind of construction work operation layer elevator shaft door place to face the frontier defense protection unit.
The utility model is achieved through the following technical solutions:
A kind of construction work operation layer elevator shaft door place faces the frontier defense protection unit, include little steel bar framework and large steel bar framework, the bottom open-ended of described large steel bar framework, the upper end of large steel bar framework and the lower end of little steel bar framework are connected through the hinge, be provided with spacing triangular steel to make the outside rotational angle range of little steel bar framework be 0 to 270 degree in the upper end of large steel bar framework, upper end at little steel bar framework is fixed with the caution slogan board by iron wire, internal welding at large steel bar framework is connected to a plurality of horizontal cross bars, vertically insert in the elevator well frame vertical rod bottom of large steel bar framework, be provided with the triangle canting quoin between large steel bar framework and elevator well frame vertical rod.
Described hinge utilizes nut and nut to be made.
Described hinge utilizes sleeve pipe and hollow round steel to add triangular steel and fixedly forms.
The surface spraying antirusting paint of described large steel bar framework and little steel bar framework.
This installs while installing in two overhanging elevator well frame pole steel tubes of large steel bar framework, use again timber wedge fastening devices and steel pipe junction, then the little steel bar framework in top being rotated to outside horizontal direction gets final product, extract timber wedge during dismounting and get final product, also upper frame can be turned to vertical direction with bottom steel stage apparatus Integral lifting.Without fixing with electric arc welding, without destroying elevator shaft support body steel pipe, save material, mounting or dismounting simply, be beneficial to turnover; This device utilizes filature nut or angle steel as spacing shelves, guarantees that the little reinforcing steel bar frame in top can only outwards turn to horizontal level, has avoided upper level protection distance building phenomenon far away.
The utility model has the advantages that: the utility model is simple to operate, safe and reliable, can gather materials on the spot, utilize the welding of engineering site waste steel bar, availability is high, makes simple, reusable, itself and elevator shaft horizontal protective device steel platform support the use, good integrity, for convenience detach, turnover recycling rate is high, light practicality, moulding are brief, good looking appearance.
The accompanying drawing explanation
Fig. 1 is the utility model elevation.
Fig. 2 is that little steel bar framework rotates 90 right views while spending.
The specific embodiment
As Fig. 1, shown in 2, a kind of construction work operation layer elevator shaft door place faces the frontier defense protection unit, include little steel bar framework 3 and large steel bar framework 6, the bottom open-ended of described large steel bar framework 6, the upper end of large steel bar framework 6 and the lower end of little steel bar framework 3 are connected by hinge 4, be provided with spacing triangular steel 5 to make the outside rotational angle range of little steel bar framework 3 be 0 to 270 degree in the upper end of large steel bar framework 6, upper end at little steel bar framework 3 is fixed with caution slogan board 2 by iron wire 1, internal welding at large steel bar framework 6 is connected to a plurality of horizontal cross bars 7, vertically insert in elevator well frame vertical rod 9 bottom of large steel bar framework 6, be provided with triangle canting quoin 8 between large steel bar framework 6 and elevator well frame vertical rod 9.
Described hinge 4 utilizes nut and nut to be made.
Described hinge 4 utilizes sleeve pipe and hollow round steel to add triangular steel and fixedly forms.
The surface spraying antirusting paint of described large steel bar framework 6 and little steel bar framework 3.
Claims (4)
