Abstract
The utility model discloses an embedded connecting device. The embedded connecting device comprises a reinforcement connecting piece, wherein a thread connector is coated at the top of the reinforcement connecting piece; folded edges are fixed at the top of the thread connector; two folded edges are provided; the tops of the folded edges are outwards inclined, and the bottoms of the folded edges are positioned at the top end, near to the two side surfaces, of the thread connector; a steel plate is mounted between the two folded edges; the two ends of the steel plate are positioned in the folded edges; a thread pipe is mounted at the lower part of the reinforcement connecting piece; an inner drum is coated at the outer side of the thread pipe; the top of the thread pipe is connected with the inner top of the inner drum, and the bottom of the thread pipe is connected with the inner bottom of the inner drum; an embedded drum is coated at the outer side of the inner drum; the embedded drum and the inner drum both adopt telescopic structures; the bottom of the embedded drum is connected with an expanding part; and the bottom of the expanding part is fixedly connected with the reinforcement connecting piece. The embedded connecting device can tightly combine an embedded device with a floor, so that the structural strength of the floor is guaranteed, the recycling can be realized, the cost is saved, the adjustment is flexible, and the installation is convenient.
Description
Technical field
The utility model relates to a kind of linkage, particularly a kind of pre-embedded connecting device.
Background technology
While carrying out pre-buried tube construction in building operations, be all directly pre-buried cylinder to be embedded in building concrete substantially, after being used to complete, need to cut off the pre-buried cylinder of exposure part outside the building by Methods of OFC-A, and pre-buried cylinder can not be reused.And after pre-buried cylinder is cut off, pipe laying after cement knock angle matsurface on hole limit, under these circumstances, easily because cement mortar is combined bad with floor, cause leaking, the phenomenon such as cracking, and if directly pre-buried, pre-buried cylinder just cannot take out, must cut, cause waste unnecessary in construction.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, providing a kind of can be closely linked pre-embedded device and floor, has guaranteed the structural strength of floor, can realize the pre-embedded connecting device of recycling simultaneously.
To achieve these goals, the technical solution adopted in the utility model is such: pre-embedded connecting device of the present utility model, comprise rebar connector, rebar connector top is arranged with screw thread coupling, screw thread coupling top is installed with flanging, flanging is two, and flanging top is tilted to outer setting, and flanging bottom is positioned at screw thread coupling top and locates near two sides, between two flangings, steel plate is installed, steel plate two ends are positioned at flanging, rebar connector bottom is provided with screwed pipe, its outside is coated with inner core, screwed pipe top is connected with inner core inner top, screwed pipe bottom is connected with inner core inner bottom part, and inner core outside is coated with pre-buried cylinder, pre-buried cylinder and inner core all adopt Collapsible structure, pre-buried cylinder bottom is connected with wide diameter portion, wide diameter portion bottom is fixedly connected with rebar connector.
Further, as a kind of concrete form of structure, wide diameter portion described in the utility model is provided with many finedraws that extend along rebar connector axis direction.
Further, as a kind of concrete form of structure, between inner core described in the utility model and pre-buried cylinder, waterproof ring muscle is installed.
Compared with prior art, the utility model has the advantage of: this pre-embedded connecting device can be closely linked pre-embedded device and floor, has guaranteed the structural strength of floor, can realize recycling simultaneously, provide cost savings, flexible adjustment, installs also very convenient in addition.
