Abstract
The utility model discloses a comprehensive well cover by concrete pouring, which is provided with an arch rib or a reinforced frustum at the bottom part; a reinforced rib passes through the reinforced structures; both ends of the reinforced rib is welded with a peripheral steel plate hoop; the reinforced structures provide good carrying capacity, save concrete by about 30% and reduce weight by about 25%; the bottom part of the steel plate hoop 4 is inclined inwards, which protects the edge of the well cover from breakage and defect and ensures that the well cover and the well base can perfectly match with each other; and the matching between inclined surfaces causes the opening of the comprehensive well cover by concrete pouring to be very convenient.
Description
Technical field
The utility model relates to a kind of precast concrete goods, and particularly a kind of steel fibrous concrete is built the concrete-pouring synthetic manhole that forms.
Background technology
The multiple steel fibrous concrete that has that uses on market is at present built the concrete-pouring synthetic manhole that forms, wherein Chinese patent 02138259.X disclosed " preparation method of wire net reinforced concrete manhole cover " is the most representative, this processing method has strengthened the intensity of concrete-pouring synthetic manhole, but in actual use, its structure is not the best, exist difficulty of processing bigger, weight is heavier, the shortcoming that waste of material is bigger.Its cross section, edge of Chinese patent 200720035632 disclosed " a kind of steel fiber reinforced concrete manhole top " is step-like, has the shortcoming of sternly not opening inconvenience with well seat closure with maintenance in the use.Chinese patent 200720151772 disclosed " gauze wire cloth enhancement mode concrete inspection well lid and water drain grid cover " has been filled the high density steel silk screen in concrete, but lacks the reinforcing rib of load-bearing in it, and flexural strength is lower.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of concrete-pouring synthetic manhole, can save 30% concrete under situation about having than high bearing capacity, alleviates 25% weight, and closed tight with the well seat, opens also very convenient during maintenance.
For solving the problems of the technologies described above, technical scheme that the utility model adopts is: a kind of concrete-pouring synthetic manhole, build by steel fibrous concrete and to form, the concrete-pouring synthetic manhole outer rim is provided with steel plate hoop, the concrete cross section of steel plate hoop and Qi Nei is for trapezoidal, and the concrete-pouring synthetic manhole bottom is provided with arched rib, and reinforcing rib comprises bending shape and linear, all reinforcing rib two ends and steel plate hoop are welded to connect, and bending shape reinforcing rib passes arched rib.Linear pattern reinforcing rib and bending shape reinforcing rib project into lattice-shaped on horizontal plane.Described reinforcing rib material is the HRB335 hot-rolled reinforced bar.
A kind of concrete-pouring synthetic manhole, build by steel fibrous concrete and to form, the concrete-pouring synthetic manhole outer rim is provided with steel plate hoop, the concrete cross section of steel plate hoop and Qi Nei is for trapezoidal, the concrete-pouring synthetic manhole top is provided with the reinforcement grid, and the bottom is provided with the reinforcement round platform, and reinforcing rib comprises bending shape and linear, all reinforcing rib two ends and steel plate hoop are welded to connect, and bending shape reinforcing rib passes the reinforcement round platform.Linear pattern reinforcing rib and bending shape reinforcing rib project into lattice-shaped on horizontal plane.Described reinforcing rib material is the HRB335 hot-rolled reinforced bar.
First kind of scheme is used in the square or rectangular synthetic manhole more, the reinforcing rib that the HRB335 hot-rolled reinforced bar is made passes the arched rib of well lid bottom, and all reinforcing rib two ends also weld together with the steel plate hoop of concrete-pouring synthetic manhole outer rim, this structure provides good supporting capacity, its failure load can reach 810KN, while has also been saved about 30% concrete use amount, weight reduction about 25%.The steel plate hoop bottom of outer rim slopes inwardly, and makes better closure of itself and well seat, and the cooperation between the inclined plane also makes the unlatching synthetic manhole very convenient.
Second kind of scheme is used for circular synthetic manhole more, the reinforcing rib that the HRB335 hot-rolled reinforced bar is made passes the reinforcement round platform, and all reinforcing rib two ends also weld together with the steel plate hoop of concrete-pouring synthetic manhole outer rim, the synthetic manhole top is provided with the reinforcement grid, this structure provides good supporting capacity, its failure load can reach 945KN, has also saved about 30% concrete use amount simultaneously, weight reduction about 25%.The steel plate hoop bottom of outer rim slopes inwardly, and makes better closure of itself and well seat, and the cooperation between the inclined plane also makes the unlatching synthetic manhole very convenient.
