Description
Technical field
The utility model belongs to design of building structures, is specifically related to a kind of for folding anti-inner water logging doorsill device in nuclear island factory building.
Background technology
After Fukushima accident, there have been renewal requirements at the higher level in newly-built autonomous Design nuclear power plant to anti-inner water logging, the fixed Concrete Anti water logging threshold of nuclear island factory building need to be constructed with agent structure simultaneously in the past, there will be that progress is nervous in advance due to civil Engineering Design, row and probabilistic contradiction after water logging zoning design, as the later stage adds concrete threshold, because Men Gaoyi is fixed, may affect current and equipment conveying height.For addressing the above problem, need a kind of main structure body design and construction that neither affect, the engineering later stage can increase at any time, collapsible, dismountable, and not impact personnel are current, the doorsill device of equipment conveying and space instructions for use.
Utility model content
The purpose of this utility model is the defect for prior art, provides a kind of and both can arrange flexibly for folding anti-inner water logging doorsill device in nuclear island factory building, can not affect again equipment conveying current.
The technical solution of the utility model is as follows: a kind of for folding anti-inner water logging doorsill device in nuclear island factory building, by some block plates, connected to form, steel plate near door one side is fixed on ground, between all the other steel plates, by hinge, connect in turn and be laid in ground, after folding, forming doorsill structure.
Further, as above for folding anti-inner water logging doorsill device in nuclear island factory building, wherein, at a block plate and the adjacent end of another block plate, be provided with chamfering structure, on described chamfering structure, be provided with compression toe joint, after threshold is folding, the compression toe joint of adjacent two block plates is laminated together.
Further, as above for folding anti-inner water logging doorsill device in nuclear island factory building, wherein, described compression toe joint is provided with rubber weather strip.
Further, as above for folding anti-inner water logging doorsill device in nuclear island factory building, wherein, the thickness of described steel plate is 20-40mm.
Further, as above for folding anti-inner water logging doorsill device in nuclear island factory building, wherein, described steel plate has six, the bar steel plate that wherein four block lengths are equal is arranged in parallel and adopts successively chain connection, other two blocks of little steel plates are arranged on the outside, longitudinal two ends near the bar steel plate of door one side, the folding rear rectangular structure that forms.
The beneficial effects of the utility model are as follows: on one side doorsill device provided by the utility model is fixed on a side of the door that needs anti-flooding, during deployed condition, be laid on ground, not impact personnel are current, equipment conveying and space instructions for use, after turning up, be a rectangular box thing, its height is determined according to anti-flooding design height.The space when connection of the section of steel plate has been considered to keep flat and folding after sealing, can increase at any time in the engineering later stage, arrange flexibly, easy to use.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
It is a kind of for folding anti-inner water logging doorsill device in nuclear island factory building that the utility model provides, by some block plates, connected to form, steel plate near door one side is fixed on ground, connects in turn and be laid in ground between all the other steel plates by hinge, after folding, forms doorsill structure.
Structure after threshold is folding is as shown in Fig. 1-1, Fig. 1-2, and the middle part of concrete wall 2 be the position of door, and the width of threshold 1 is slightly wider than the width of door, the forward lower part being positioned at after threshold 1 is folding, 3 certain height above ground level.
Structure after threshold launches is as shown in Fig. 2-1, Fig. 2-2, and the threshold 1 after expansion is laid in ground 3, and basic concordant with the height on ground after tiling, not impact equipment is current.
Embodiment
What the present embodiment provided is put together by six blocks of steel plates for folding anti-inner water logging doorsill device in nuclear island factory building, and steel plate thickness can be 20-40mm, and gross thickness can, within the surface layer 50mm scope of ground, not affect main structure body.As shown in Fig. 2-1, the bar steel plate that wherein four block lengths are equal of six block plates is arranged in parallel and adopts successively chain connection, other two blocks of little steel plates are arranged on the outside, longitudinal two ends near the bar steel plate of door one side, between little steel plate and bar steel plate, be also connected through the hinge, the folding rear rectangular structure that forms.Four bar steel plates form upper and lower, forward and backward four faces of cuboid, and two blocks of little steel plates form left and right two faces of cuboid.
The size of steel plate is definite according to the calculated height of threshold, and the steel plate of close door one side is fixed on ground, and all the other steel plates are mobilizable form, and connected mode as shown in Figure 3, Figure 4, connects by hinge 5 between steel plate 4.At a block plate and the adjacent end of another block plate, be provided with chamfering structure, be provided with and compress toe joint 6 on described chamfering structure, after threshold is folding, the compression toe joint 6 of adjacent two block plates is laminated together.In one of them of two compression toe joints 6 that are laminated, be provided with rubber weather strip 7, when being provided with the steel plate of rubber weather strip 7, turn up after 90 °, compression toe joint 6 pressings on two block plates, rubber weather strip 7 is by contact surface sealing in neat formation.
The utility model does not affect main structure body design and construction, and the engineering later stage can increase at any time, collapsible, dismountable, and not impact personnel are current, equipment conveying and space instructions for use.
Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model the utility model.Like this, if of the present utility model these are revised and within modification belongs to the scope of the utility model claim and equivalent technology thereof, the utility model is also intended to comprise these changes and modification interior.
