Description
Technical field
The utility model belongs to the realm of building construction, is specifically related to a kind of for top mould system support box beam falling proof device.
Background technology
Increasing required top mould system in current construction of super highrise building, top mould system is to be supported on concrete wall by support box beam.Case beam is divided into nowel beam, when backform climbs, first nowel beam is supported on body of wall, by hydraulic jack, top box back is risen to after a structure floor height, then top box beam is supported on body of wall, then oil cylinder is regained, nowel beam is promoted to former top box beam position, realizes climbing of a floor height.But, in case beam lifting process, between upper and lower case beam, only rely on hydraulic jack to link, if there is chance failure in hydraulic jack, while easily causing top box beam to promote nowel beam fall, the nowel beam risk that top box beam falls while regaining, cause security incident.
Utility model content
It is a kind of for top mould system support box beam falling proof device that the technical problems to be solved in the utility model is to provide, it can limit when top box back rises, and top box beam moves downward, nowel beam limits nowel beam while regaining and moves downward, guard box beam can not occur because of the chance failure of oil cylinder falling in motion process, increases the safety that backform system is used.
The utility model solves the technical scheme that its technical problem adopts:
Provide a kind of for top mould system support box beam falling proof device, comprise inner sleeve steel pipe, outer steel pipe, keep plate and spring, the bottom of described inner sleeve steel pipe is fixedly installed on nowel beam, it is outside that top box beam is stretched out at top, the periphery of described inner sleeve steel pipe is evenly offered ring rib in its length range, described inner sleeve steel pipe socket is contained in outer steel pipe, the top of described outer steel pipe is fixedly installed on top box beam, the bilateral symmetry of described outer steel pipe offers two square shaped holes, one end and the outer steel pipe of described keep plate are hinged, articulated position is positioned at the centre in two square shaped holes, the other end of described keep plate is set square, the base angle of described set square is arranged between adjacent two ring ribs through square opening, described spring housing is contained in keep plate outside.
By technique scheme, the length of described inner sleeve steel pipe is greater than the twice of nowel beam single lift height.
By technique scheme, the thickness of described keep plate is less than the width of square opening, and the height of described set square is less than the height of square opening.
By technique scheme, the steel plate that described keep plate is more than or equal to 20mm by thickness is made.
The utility model, there is following beneficial effect: this device is by arranging keep plate and spring, can be so that outer steel pipe or inner sleeve steel pipe can only one-way movements, once outer steel pipe or inner sleeve steel pipe, there is heterodromous trend, the triangle board of keep plate will be stuck between ring rib, restriction outer steel pipe or the counter motion of inner sleeve steel pipe, thus guard box beam can not occur because of the chance failure of hydraulic jack falling in motion process, increases the safety that backform system is used.
Concrete, when nowel beam is supported on body of wall stressed, when top box back rises, the set square of keep plate is rotated down to the square opening of outer steel pipe below, and now set square is equilateral triangle, and keep plate is under the effect of spring, can be along with outer steel pipe moves upward, once outer steel pipe, have the trend moving downward, the set square of keep plate will be stuck between the ring rib of inner sleeve steel pipe, and restriction outer steel pipe moves downward; In like manner, when top box beam is supported on body of wall stressed, when nowel beam is regained, the set square of keep plate rotates up to the square opening of outer steel pipe top, and now set square is del, and keep plate is under the effect of spring, can move upward along with inner sleeve steel pipe, once inner sleeve steel pipe, have the trend moving downward, the set square of keep plate will be stuck between the ring rib of inner sleeve steel pipe, and restriction inner sleeve steel pipe moves downward.

The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
In preferred embodiment of the present utility model, as shown in Fig. 1～Figure 11, a kind of for top mould system support box beam falling proof device, comprise inner sleeve steel pipe 1, outer steel pipe 2, keep plate 3 and spring 4.The bottom of inner sleeve steel pipe 1 is bolted and is arranged on nowel beam 6, and top box beam 5 outsides are stretched out at top, and the length of inner sleeve steel pipe 1 is greater than the twice of nowel beam 6 (or top box beam) single lift height.The periphery of inner sleeve steel pipe 1 is evenly offered ring rib 100 in its length range, and ring rib 100 can mill out by machine tool.Inner sleeve steel pipe 1 is sleeved in outer steel pipe 2, and both can be movable relatively.The top of outer steel pipe 2 is bolted and is arranged on top box beam 5, and the bilateral symmetry of outer steel pipe 2 offers two square shaped holes 200.One end of keep plate 3 and outer steel pipe 2 are hinged, articulated position is positioned at the centre in two square shaped holes 200, the other end of keep plate 3 is set square 300, the base angle of set square 300 is arranged between adjacent two ring ribs 100 through square opening 200, and the set square 300 of keep plate 3 can be around its hinged one end rotation to the square opening of top or the square opening of below.The steel plate that keep plate 3 is more than or equal to 20mm by thickness is made, and the thickness of keep plate 3 is less than the width of square opening 200, and the height of set square 300 is less than the height of square opening 200.Spring 4 is sleeved on keep plate 3 outsides, and one end hinged near keep plate arranges, and spring can be pressed in keep plate elasticity on inner sleeve steel pipe.
Operating principle of the present utility model is: when nowel beam is supported on body of wall stressed, when top box back rises, the set square of keep plate is rotated down to the square opening of outer steel pipe below, now set square is equilateral triangle, keep plate, under the effect of spring, can move upward along with outer steel pipe, has the trend moving downward once outer steel pipe, the set square of keep plate will be stuck between the ring rib of inner sleeve steel pipe, and restriction outer steel pipe moves downward; In like manner, when top box beam is supported on body of wall stressed, when nowel beam is regained, the set square of keep plate rotates up to the square opening of outer steel pipe top, and now set square is del, and keep plate is under the effect of spring, can move upward along with inner sleeve steel pipe, once inner sleeve steel pipe, have the trend moving downward, the set square of keep plate will be stuck between the ring rib of inner sleeve steel pipe, and restriction inner sleeve steel pipe moves downward.The utility model can not occur because of the chance failure of hydraulic jack falling by guard box beam in motion process, increases the safety that backform system is used.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
