Description
Technical field
The utility model relates to pvc pipe technical field, specifically a kind of pre-buried PVC drain pipe hoop.
Background technique
In urban construction, pvc pipe is widely used in fuel gas transmission and water network construction, though have lightweight compared with steel pipe, cast iron tube, and the advantages such as corrosion-resistant, easy construction, life-span are long.Along with the development of society, multilayer or tall building increasing, pre-buried hoop, without effective position structure, is directly placed on timber formwork during construction by the pre-buried PVC drain pipe hoop of current passing through floors.
The pre-buried pvc pipe hoop of said structure, due to the defect of position structure, easily movement in work progress, causes very large puzzlement to construction, greatly reduces working efficiency.
Model utility content
Technical assignment of the present utility model provides a kind of pre-buried PVC drain pipe hoop for above-mentioned deficiency of the prior art, and this kind of pre-buried pipe collar can realize the location of itself and timber formwork, efficiently solves the problem of constructional difficulties.
The utility model solves the technological scheme that its technical problem adopts: this kind of pre-buried PVC drain pipe hoop, is characterized in that, its structure comprises a columniform housing, and turning edge outside the lower end mouth of described housing is provided with several strip through-holes; Described housing is fixed by the fastening screw in strip through-hole and timber formwork;
Described inner walls is provided with several annular boss, the diameter of described annular boss and the external diameter interference fit of PVC drain pipe;
The outer surface of the upper end-hole of described housing is provided with positioning boss, the fit depressions on described positioning boss and cover plate.
Preferably, the place of two-port up and down of described housing is equipped with guiding surface.
Preferably, the positioning boss on described housing is ladder structure of right angle.
Preferably, the quantity of the strip through-hole on described housing is no less than 4.
The utility model has following outstanding beneficial effect:
1, because its structure comprises a columniform housing, turning edge outside the lower end mouth of described housing is provided with several strip through-holes; Described housing is fixed by the fastening screw in strip through-hole and timber formwork, and therefore, during use, this kind of pre-buried pipe collar can be fixed on timber formwork, improves the working efficiency of construction.
2, because described inner walls is provided with several annular boss, the diameter of described annular boss and the external diameter interference fit of PVC drain pipe, therefore, during use, ring position boss can prevent the phenomenon occurring between the inwall of housing and PVC drain pipe seeping water.
3, because the outer surface of the upper end-hole of described housing is provided with positioning boss, the fit depressions on described positioning boss and cover plate, therefore, during use, this kind of cooperating structure prevents cover plate from departing from from housing upper end-hole in work progress.
Accompanying drawing explanation
Fig. 1 of the present utility modelly partly cuts open structural representation;
Fig. 2 is the structural representation of Fig. 1 middle shell.
Description of reference numerals: 1 cover plate, 2 grooves, 3 housings, 4 fastening screws, 5 strip through-holes, 6 guiding surfaces, 7 annular boss, 8 positioning boss.
Embodiment
Be described embodiment of the present utility model below in conjunction with accompanying drawing, embodiment does not form restriction of the present utility model:
As shown in Figure 1 and Figure 2, this kind of pre-buried PVC drain pipe hoop, its structure comprises a columniform housing 3, and turning edge outside the lower end mouth of described housing 3 is provided with several strip through-holes 5; Described housing 3 is fixed with timber formwork by the fastening screw 4 in strip through-hole 5.During use, this kind of pre-buried pipe collar is fixed on timber formwork, easy to operate during Embedment Construction, improves the working efficiency of construction.
In above-described embodiment, concrete, described housing 3 inwall is provided with several annular boss 7, the diameter of described annular boss 7 and the external diameter interference fit of PVC drain pipe.During use, ring position boss 7 can prevent the phenomenon occurring between the inwall of housing 3 and PVC drain pipe seeping water.
In above-described embodiment, concrete, the outer surface of the upper end-hole of described housing 3 is provided with positioning boss 8, and described positioning boss 8 matches with the groove 2 on cover plate 1.During use, this kind of cooperating structure prevents cover plate 1 from departing from from housing 3 upper end-hole, avoids at work progress middle shell 3 lumen blockage.
In above-described embodiment, more specifically, the place of two-port up and down of described housing 3 is equipped with guiding surface 6.During use, by the effect of guiding surface 6, be convenient to PVC drain pipe and insert in housing.
In above-described embodiment, more specifically, the positioning boss 8 on described housing 3 is ladder structure of right angle.During use, this kind of structure can effectively prevent cover plate 1 from departing from from housing 3.
In above-described embodiment, more specifically, the quantity of the strip through-hole 5 on described housing 3 is no less than 4.During use, can be fastened on timber formwork according to the strip through-hole 5 of selection correct position that needs of PVC drain pipe.
The pre-buried PVC drain pipe hoop of one of the present utility model, by cooperatively interacting of housing and cover plate, achieve the function that this kind of pre-buried pipe collar and timber formwork are located, it is simple to operate, efficiently solves the problem of constructional difficulties.
The above, be only preferred embodiment of the present utility model, not does any pro forma restriction to the utility model.Any those of ordinary skill in the art; do not departing under technical solutions of the utility model ambit; technology contents described above all can be utilized to make many possible variations and modification to technical solutions of the utility model; or the Equivalent embodiments being revised as equivalent variations therefore; every content not departing from technical solutions of the utility model; according to technology of the present utility model to any change amendment made for any of the above embodiments, equivalent variations and modification, all belong to the protection domain of the technical program.
