Description
Technical field
The utility model relates to a kind of safety protective door for elevator hoistways, belongs to the realm of building construction.
Background technology
Along with the raising of expanding economy and people's living standard, people have higher requirement to house, and little high level, high-rise building get more and more, and wherein just must use vertical lift.In house building course, be usually all reserved with drainpipe well, strong and weak electricity pipe well road and elevator hoistways, the elevator hoistways potential safety hazard of wherein opening wide is maximum, and security protection workload is also maximum.
For the problems referred to above, prior art is all adopt safety protective door to block elevator hoistways, thus stops potential safety hazard.As Chinese invention patent application CN101503910A discloses safety protecting method and the device of elevator hoistways in a kind of house building course, the protective cover plate that its protector used is the reinforced mesh that coincide with elevator hoistways size and it is added a cover; Described reinforced mesh is welded across a certain distance mutually by longitudinal and transverse some reinforcing bars and forms, and described longitudinal and transverse some reinforcing bars extend certain size in the rectangle mesh sheet outer rim formed, and described protective cover plate is connected with reinforced mesh colligation in its corner.Its concrete mounting method is: when the assembling reinforcement of agent structure floor, anchors in the surrounding of agent structure floor or the reinforcing bar of floor by the reinforcing bar that described reinforced mesh surrounding outer rim extends certain size; After elevator rail installation, special messenger during lift-mounting, is sent successively to cut off dismounting from top to bottom from elevator hoistways, for elevator installation personnel lift-mounting.As can be seen here, this protective door is fixed on elevator hoistways doorway.But this mode causes cannot adjusting elevator hoistways or carrying out other operations in building construction process, limit its application.
For the problems referred to above, there is the protective door of retractable structure, as Chinese utility model patent CN203112313U discloses a kind of elevator hoistways safety protective door, comprised protective door, also comprise door-hinge ear seat, fixed hook ear seat, door-hinge peg and door-hinge hook; Described door-hinge ear seat is fixed in the middle part of elevator hoistways door opening, and fixed hook ear seat is fixed on elevator hoistways door opening top, and the distance between door-hinge ear seat and fixed hook ear seat is the height of protective door; The top margin of the angle steel doorframe of described protective door fixes door-hinge peg, and door-hinge hook is fixed on its base; Door-hinge peg is connected with door-hinge ear seat, and door-hinge hook is connected with fixed hook ear seat.Thus achieve the unlatching up and down of protective door, achieve protective door under unlatching, closing two states, all the safety of energy effective guarantee operating personnel.
But, the complicated structure of above-mentioned safety protective door, preparation difficulty and cost all higher; In addition, this safety protective door needs to construct (namely installing door-hinge ear seat, fixed hook ear seat) to the metope of elevator hoistways when mounted, and thus construction sequence is more, operates cumbersome.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of safety protective door for elevator hoistways.
To achieve the above object of the invention, the technical solution adopted in the utility model is: a kind of safety protective door for elevator hoistways, comprise protective door, the back side of described protective door is provided with the connecting rod of at least 1 level, the two ends of connecting rod are arranged with a pair sleeve pipe be slidably connected, each sleeve pipe is all installed with L shape holding firmware, the block end of L shape holding firmware stretches out and coordinates with elevator hoistways body of wall.
Above, described protective door is existing structure, and generally welded across a certain distance mutually by longitudinal and transverse some reinforcing bars and form, surrounding is provided with doorframe.
The connecting rod at the back side of described protective door can be fixedly installed on doorframe, thus and forms certain distance between mesh sheet.
The connecting rod at the back side of described protective door can adopt round steel, and sleeve pipe can adopt short steel pipes.These are all the standing material in job site or additional waste material of constructing.
Preferably, the back side of described protective door is provided with the connecting rod of 2 levels, lays respectively at the upper and lower of protective door.
In technique scheme, described L shape holding firmware is L shape reinforcing bar.Reinforcing bar is seen everywhere at the construction field (site), thus achieves slug detect.
Use procedure of the present utility model is as follows:
(1) when needing protective door is installed, first a pair sleeve pipe at the protective door back side is moved inward some distances, the distance between the L shape holding firmware on it is made to be less than the width of elevator hoistways, then protective door is attached on elevator hoistways body of wall, finally lift L shape holding firmware (being generally make L shape holding firmware be in horizontal position) and outwards move above-mentioned sleeve pipe, finally make the L shape holding firmware on it while offset with elevator hoistways body of wall, now, decontrol sleeve pipe, L shape holding firmware on it can be sagging under self gravitation effect, elevator hoistways body of wall is fastened with the deadweight of L shape holding firmware, protective door is made to be fastened on elevator hoistways body of wall,
(2), when needing opening protection function door, as long as first lift L shape holding firmware (being generally make L shape holding firmware be in horizontal position), then move inward sleeve pipe, make the distance between L shape holding firmware be less than the width of elevator hoistways, can protective door be taken out.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1. the utility model design obtains a kind of security protection door being specifically designed to elevator hoistways newly, not only can realize opening, closing two states, the safety of effective guarantee operating personnel, and structure is simple, preparation is easy, do not need additionally to construct to the metope of elevator hoistways, thus there is splendid realistic meaning;
2. the utility model have employed the fit structure of sleeve pipe and L shape holding firmware, fastens elevator hoistways body of wall by the deadweight of L shape holding firmware, protective door is fastened on elevator hoistways body of wall, achieves the closedown of protective door, and operation is very simple, is easy to realize;
3. structure of the present utility model is simple, and easy to prepare, cost is lower, is suitable for applying.
