Description
Technical field
The invention belongs to the scaffold field of mainly being supported by building structure, be specifically related to a kind of telescopic steel platform for elevator shaft.
Background technology
Along with the development of builing industry, highrise building is also more and more, because the elevator shaft of highrise building has narrow space, highly large and without working platform, so want erection construction platform when constructing operation.
The form of construction work of existing elevator shaft mainly contains two kinds, and one is in elevator shaft, to prick to establish full hall support scaffolding, and another kind is to use elevated platform.First kind of way connects continuously cross shear support is set to top from elevator shaft bottom, and on scaffold the steel platform of erection construction, taken a large amount of constructional materialss such as frame pipe, buckle and construction is inconvenient; Support body is set up higher, easily caves in, falling accident.The main shortcoming of the second way has: 1. require the size of steel platform and the elevator hoistways size of construction to match, a kind of steel platform of size can only use in corresponding hoistway; 2. 4 reserved openings (respectively establishing 2 on relative well enclosure) of setting up for steel pipe at least will be set on the well enclosure of elevator hoistways, and the position of 4 reserved openings to very accurately could coordinate steel pipe to insert; 3. while removing the steel pipe being inserted in reserved opening, 4 holes place all will remove, operation more complicated.
Summary of the invention
The defect existing for above-mentioned prior art, the object of the present invention is to provide one in sizes elevator hoistways, to use, available tower crane promotes, and installation, dismounting and lifting platform are convenient, can reduce the telescopic steel platform for elevator shaft of the probability of security incident generation.
For achieving the above object, technical scheme of the present invention is: for the telescopic steel platform of elevator shaft, comprise steel pipe girder, inferior girder steel and operating platform, wherein, also be provided with main girder steel, set up base and turnover platform, at least be provided with two steel pipe girders that are parallel to each other, spacing is less than the width of elevator shaft door opening outside two steel pipe girders in outside, and described girder steel and steel pipe girder are connected to form the framework of rectangle; Described steel pipe girder two ends are equipped with locating hole, in being equipped with, described steel pipe girder two ends are placed on main girder steel wherein, described main girder steel insertion end is provided with the fixing hole that coordinates locating hole and regulate main girder steel extension elongation, and steel pipe girder is connected by bolt and latch with main girder steel; Described operating platform is located on framework; The steel pipe girder two ends in outside are equipped with the base of setting up upward, on two steel pipe girders in outside, are equipped with turnover platform, and described turnover platform and steel pipe girder are hinged.
Adopt when technique scheme, steel pipe girder two ends are all arranged with main girder steel, and main girder steel can stretch in steel pipe girder one end, main girder steel stretch out or retraction after, insert by bolt and latch the locating hole and the fixing hole that cooperatively interact and fix.When use, main girder steel stretches out and fixes, because two steel pipe girder spacing in outside are less than the width of elevator shaft door opening, the main girder steel of steel pipe girder one end inserts in the reserved opening of elevator shaft, the main girder steel of the other end is set up on the floor of elevator shaft door opening, then the turnover platform arranging on outermost steel pipe girder is opened towards steel pipe girder outside, constructor set up on base can erection construction support body, constructor can construct on support body or on operating platform; While carrying lift steel platform, first with tower crane, steel pipe girder is sling, by the main girder steel retraction at steel pipe girder two ends, and fixed by bolt and latch, then tower crane upwards promotes whole steel platform, is erected on next construction location.The present invention is for the telescopic steel platform of elevator shaft, two steel pipe girder spacing in outside are less than the width of elevator shaft door opening, can be positioned in the narrowest elevator shaft, on two steel pipe girders in outside, be equipped with turnover platform, elevator hoistways hour, the angle of turnover platform upset is little, turnover platform outside rides in hoistway wall, when elevator hoistways is larger, the angle of turnover platform upset is large, can open completely, the no matter size of hoistway, all can ensure the sealing of steel position of platform hoistway by turnover platform, so the present invention goes for the elevator hoistways of different size, further, while carrying lift steel platform, only need, by also fixing in all main girder steel retraction steel pipe girders, just can use tower crane that whole steel platform is upwards promoted, without the operation of other complexity, and the steel platform that can promote has been avoided setting up the high potential safety hazard existing because of support body, in addition, because the main girder steel of steel pipe girder one end is set up on the floor of elevator shaft door opening, only need establish 2 reserved openings in the relative side of elevator shaft door opening, only need to ensure that the spacing of 2 reserved openings and the spacing of main girder steel equate, and 2 reserved openings and floor are contour, do not depart from the just right region of door opening, the positional accuracy of reserved opening reduces.In addition, owing to being inserted in main girder steel operation in reserved opening more complicated, the present invention has reduced the quantity of reserved opening, the operation that just can simplify main girder steel insertion reserved opening or split out from reserved opening, so installation, dismounting and lifting platform are convenient.
Further, described turnover platform comprises turnover housing, protective screening and the reinforcing rib of rectangle, be provided with two reinforcing ribs that weld with turnover housing, protective screening is welded on turnover housing, one side and the steel pipe girder of turnover housing are hinged by three hinges, can turn down by the hinged turnover platform of hinge with steel pipe girder, so can use in the elevator shaft of sizes.
Further, described steel pipe girder two ends are respectively equipped with two locating holes, and arrange along steel pipe girder length direction, described main girder steel insertion end is provided with three fixing holes, the spacing of adjacent two fixing holes equates with the spacing of two locating holes, three two adjacent fixing holes of fixing hole coordinate with two locating holes, and corresponding main girder steel stretches out and the position of retraction respectively.
Further, described steel pipe girder two ends are respectively equipped with three locating holes, and arrange along steel pipe girder length direction, described main girder steel insertion end is provided with two fixing holes, the spacing of adjacent two locating holes equates with the spacing of two fixing holes, two locating holes adjacent in three locating holes coordinate with two locating holes, and corresponding main girder steel stretches out and the position of retraction respectively.
Further, described steel pipe girder two ends are equipped with caging bolt, by after main girder steel retraction steel pipe girder, directly by caging bolt, main girder steel are locked, and can prevent that main girder steel skids off in the time carrying lift steel platform.
Further, described steel pipe girder two ends are equipped with suspension ring, and when suspension ring are set conveniently carry lift steel platform, tower crane finds fast the position of the application of force on steel pipe girder.
Further, described main girder steel exposed junction is provided with draw ring, and it is all constructor's manual operation that main girder steel stretches out with retraction in girder steel supervisor, and draw ring can make more convenient operation.
