Background technology
Along with science and technology and socioeconomic fast development, the use in soil is also more and more nervous, and highrise building has become the main method of alleviating land supply anxiety.But the rise of highrise building will be accompanied by the generation of a large amount of construction safety problems; Wherein, around construction building, setting up protection canopy is to provide one of subject matter of safety guarantee for ground or upper strata constructor.The primary structure of more common protection canopy is with steel pipe and fastener, to set up platform on the shaped steel of encorbelmenting on the market, re-lay bamboo raft or plank on platform, this kind of method only can play elementary protection object, but in practice of construction with in using, still there is many drawbacks: 1, for aspect the height of building, building just need to be built a set of protection canopy every 24 meters, for the higher building of those floors, will waste a large amount of material costs and human cost; 2, the speed that protection canopy is set up is very slow, complex operation, and also danger coefficient is higher; 3, the bulk strength of protection canopy is inadequate, and the steel pipe falling from eminence is probably inserted and worn protection canopy structure; 4, the scope of protection is narrower, cannot accomplish the protection of maximum magnitude; 5, timber and some connectors are apt to rot, damage and be difficult for change; Meanwhile, do not form the general volume of modular protection canopy assembly larger or too scattered, be extremely unfavorable for collecting, transport and install.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, aim to provide a kind of protection canopy base plate simple in structure, easy for installation and only need once to build, can Reusability, can need according to construction the automatic lifting protection canopy of automatic lifting simultaneously.
The technical scheme that protection canopy base plate in the present invention adopts is: it comprises a metal sheet, be welded on the hog frame of described metal sheet below and fixed packet is wrapped in the angle steel frame of described metal sheet surrounding, the square tubes soldering that described hog frame is arranged by some transverse and longitudinals forms, and described angle steel frame is provided with the screwed hole for being connected with other base plates.
Further, on described angle steel frame, be also provided with reinforced sheet.
The technical scheme that automatic lifting protection canopy in the present invention adopts is: it comprises described protection canopy base plate, guide rail, adjustable drawbar and lifting appliance, described guide rail and out-building are slidably connected, one end of described protection canopy base plate is connected with fence board, its other end is flexibly connected with the bracnig frame being arranged on described guide rail, one end of described adjustable drawbar connects described protection canopy base plate, its other end is fixedly connected with described guide rail, on described guide rail, be also provided with hanging piece, one end of described lifting appliance connects out-building, and its other end connects the described hanging piece that rises.
Further, described guide rail is slidably connected by the anti-dumping anti-fall guiding off-load bearing and the out-building that are fixed on out-building.
Further, one end of described adjustable drawbar is connected with described protection canopy base plate by steel pipe connecting connected components; Described steel pipe connecting connected components comprises at least two steel-tube seats being fixed on described protection canopy base plate, through steel-tube seat the steel pipe being fixedly connected with steel-tube seat described in two and the latch hook of clasp joint on described steel pipe described in two, described latch hook is fixedly connected with one end of described adjustable drawbar.
Further, described protection canopy base plate is flexibly connected with described bracnig frame by protection canopy coupling assembling, described protection canopy coupling assembling comprises and is fixedly connected on the connector I on described protection canopy base plate and is fixedly connected on the connector II on described bracnig frame, and described connector I and described connector II are spacing hinged.
Further, described automatic lifting protection canopy also comprises fence board diagonal member, and one end of described fence board diagonal member is fixedly connected with described fence board, and its other end is fixedly connected with described protection canopy base plate.
Further, described automatic lifting protection canopy also comprise turnover panel and be fixed on described bracnig frame in choose angle steel, one end of described turnover panel by hinge and described in choose angle steel and be rotationally connected, the other end of described turnover panel is overlapped on out-building.
Further, described lifting appliance is electric block or air hoist or hydraulic screw extractor.
The invention has the beneficial effects as follows: because the protection canopy base plate in the present invention comprises a metal sheet, be welded on the angle steel frame that the hog frame of described metal sheet below and fixed packet are wrapped in described metal sheet surrounding, the square tubes soldering that described hog frame is arranged by some transverse and longitudinals forms, described angle steel frame is provided with the screwed hole for being connected with other base plates, so described protection canopy base plate is not only simple in structure, durable, and the plank compared to existing technology or bamboo raft, the intensity and the application life that adopt metal material as base plate, more to improve base plate, reduced its frequency of maintenance, simultaneously, because the automatic lifting protection canopy that comprises described protection canopy base plate also comprises guide rail, adjustable drawbar and lifting appliance, described guide rail and out-building are slidably connected, one end of described protection canopy base plate is connected with fence board, its other end is flexibly connected with the bracnig frame being arranged on described guide rail, one end of described adjustable drawbar connects described protection canopy base plate, its other end is fixedly connected with described guide rail, on described guide rail, be also provided with hanging piece, one end of described lifting appliance connects out-building, its other end connects the described hanging piece that rises, so the automatic lifting protection canopy in the present invention is not only by adopting modular splicing greatly to improve the speed of building of protection canopy, simplify the step of building of protection canopy, potential safety hazard when reduction protection canopy is built, and under the cooperation of lifting appliance and guide rail, make protection canopy can automatic lifting to each floor, and then without wasting a large amount of materials and manually carrying out layering and build, really realized once and having built, the theory of Reusability.
