Abstract
A special integral framework without welding spots for a manhole cover is characterized by comprising an outer frame, an inner frame and a plurality of support boards, wherein two ends of each of the support boards are respectively fixedly connected with the outer frame and the inner frame, the support boars are provided with through holes, and the outer frame, the inner frame and the support boards are in cast-iron-poured integral structures. The special integral framework without welding spots has the advantages of 1, capability of reaching standards of steel fiber reinforced concrete above C50cm and adapting to all road manhole covers, 2, formation by one-step pouring without the welding spots, and breakage resistance, 3, high strength, long service life, 4, convenience in use, adaptability to mass production, and 5, certain antitheft function.
Description
Technical field
The utility model relates to urban construction facility technology field, specifically is that the special-purpose solderless of a kind of well lid is put whole skeleton.
Background technology
In the prior art, the well lid in the urban construction facility adopts mostly that cast iron is integrated poured to form, and except that stolen easily, its compressive strength is also often nonconforming and by the heavy-duty car pressure break, cause the accident; On the other hand, though the bulk strength of less its structure of stolen situation of cement well lid is not high yet mostly, also be prone to damage, application life is short.
Summary of the invention
The purpose of this utility model provides the special-purpose solderless of well lid of a kind of intensity height, long service life and puts whole skeleton.
The special-purpose solderless of described well lid is put whole skeleton, and it is characterized in that: it comprises housing, inside casing, a plurality of gripper shoe, fixedlys connected with housing, inside casing respectively in a plurality of gripper shoes two ends, and gripper shoe is provided with through hole; Described housing, inside casing and a plurality of gripper shoe are the cast iron casting overall structure.
The beneficial effects of the utility model are: 1, can reach the above specification of steel fiber concrete C50cm, be applicable to all manholes; 2, once casting forms no pad, not easy fracture; 3, intensity height, long service life; 4, easy to use, be suitable for producing in enormous quantities; 5, has certain antitheft effect.
