Abstract
The invention provides a high-pressure-bearing economical inspection well lid. A two-layer hollow steel tube lagging jack is embedded into a body of an inspection well lid plate. When any portion of the inspection well lid plate bears pressure, the pressure can be transmitted to the whole inspection well lid plate fast through the two-layer hollow steel tube lagging jack. Due to the fact that the pressure is transmitted and shared evenly, the inspection well lid plate can not be damaged by pressing. The stress points of the inspection well lid plate and the stress points of an inspection well lid seat are equal in bearing pressure, and therefore the inspection well lid plate can bear larger pressure. The high-pressure-bearing economical inspection well lid has the advantages of being high in bearing force, low in cost, light in weight, strong in shock resistance and fatigue resistance, convenient to open, attractive and durable, and meeting requirements of an urban modernization image.
Description
Technical field: the present invention relates to inspection shaft lid, steel work etc.
Background technology: the inspection shaft lid that uses at present presents unreasonable structure more, and improper with material, pressure-bearing is lower, be worth to deviate from rule, and stolen phenomenon is general, and disappearance is serious, brings many worries to daily life.
Summary of the invention: in order to overcome above deficiency, the invention provides the economical inspection shaft lid of a kind of high pressure-bearing, thoroughly change utilizes the using method of cover plate of manhole bearing pressure separately, is the brand-new application theory that a bearing integral uses with cover plate of manhole, inspection shaft lid well seat and the triplicity of inspection shaft pedestal.
The present invention solves the technical scheme that its technical problem takes: the main body at cover plate of manhole is implanted into double-layer hollow steel pipe bow member; In the main body of inspection shaft lid well seat, near inner corner trim and external corner place, each implants outer pressure-bearing carriage and the interior pressure-bearing carriage of annular hollow steel pipe.The two ends extended line of every group of arch tube of cover plate of manhole upper strata bow member is aimed at the inner corner trim of inspection shaft lid well seat; The two ends extended line of every group of arch tube of cover plate of manhole lower floor bow member is aimed at the external corner of inspection shaft lid well seat.Double-layer hollow steel pipe bow member in inspection shaft lid main body above the center, the below of Sign Board crosses, and is connected with the Sign Board structure.Mansion angle between each adjacent hollow steel pipe bow member equates.The back of the body of cover plate of manhole main body (descending) face is arranged to the spheroid groove, in order under the prerequisite that does not reduce pressure-bearing, alleviates the weight of cover plate of manhole.Cover plate of manhole and inspection shaft cover between the well seat, inspection shaft covers between well seat and pedestal and must accomplish seamless combination, and the three forms the organic combination of a pressure-bearing.When the pressure-bearing Anywhere of cover plate of manhole, by double-layer hollow steel pipe bow member pressure promptly is delivered to cover plate of manhole on the whole, and is passed on the annular hollow steel pipe pressure-bearing carriage, again to the pedestal of inspection shaft to inspection shaft lid well seat.Because the transmission of pressure and evenly sharing is unlikely that just cover plate of manhole is squished; The present invention is provided with double-layer hollow steel pipe bow member and annular hollow steel pipe pressure-bearing carriage, and the pressure-bearing of the stress point everywhere of cover plate of manhole and inspection shaft lid well seat is equal substantially, so cover plate of manhole just can be born bigger pressure.
The invention has the beneficial effects as follows, the bearing capacity height, cost is low, and is in light weight, and the shock resistance fatigue resistance is strong, and it is convenient, attractive and durable to open, and meets the requirement of urban modernization image.
Description of drawings: the present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is double-deck bow member structural representation of the present invention.
Fig. 2 is overall structure schematic diagram of the present invention.
1. upper strata bow members among Fig. 1 Fig. 2,2. lower floor's bow member, 3. Sign Board, 4. the cover plate of manhole main body, 5. lifting eye, 6. the well seat, 7. outer pressure-bearing carriage, 8. the spheroid groove, 9. in pressure-bearing carriage, 10. pedestal.
The specific embodiment: be implanted into double-layer hollow steel pipe bow member in cover plate of manhole main body (4); In the main body of inspection shaft lid well seat (6), near inner corner trim and external corner place, each implants outer pressure-bearing carriage (7) and the interior pressure-bearing carriage (9) of annular hollow steel pipe.The two ends extended line of every group of arch tube of cover plate of manhole upper strata bow member (1) is aimed at the inner corner trim of inspection shaft lid well seat (6); The two ends extended line of every group of arch tube of cover plate of manhole lower floor bow member (2) is aimed at the external corner of inspection shaft lid well seat (6).The top center of double-layer hollow steel pipe bow member in cover plate of manhole main body (4), the below of Sign Board (3) crosses, and is connected with Sign Board (3) structure.Mansion angle between each adjacent hollow steel pipe bow member equates.The back of the body of cover plate of manhole main body (4) (descending) face is arranged to spheroid groove (8).Cover plate of manhole and inspection shaft cover between well seat (6), inspection shaft covers between well seat (6) and pedestal (10) and must accomplish seamless combination, and the three forms the organic combination of a pressure-bearing.
