A kind of shuttering supporting pipe
Technical field
The utility model relates to the stay pipe that building-supporting template is used, and especially relates to the stay pipe between two relative construction formworks in steel bar concrete casting process.
Background technology
Steel bar concrete refer to by concrete, add reinforcing bar with it co-operation improve a kind of combined material of Concrete Mechanical Properties, in concrete manufacturing process, before concreting, first tie up muscle formwork, namely with iron wire, reinforcing bar is fixed into the planform of wanting, then by template, covers cage of reinforcement outside.Finally concreting is entered, form removal after maintenance reaches strength criterion.There is in the market a kind of quick-clamping concrete-pouring template, by polylith construction formwork, adopt screw rod, stay pipe with spiral shell dish, relative two dull and stereotyped construction formworks to be locked, have advantage is rapidly installed.
Stay pipe has use bamboo trunk at present, after cement pouring, bamboo trunk need to be beaten out, then fills cement; Because the hole of beaing is irregular, be difficult to ensure the adhesive power of the rear moisturizing mud of card, easily there is percolating water.Have the old metal hollow pipe of employing, after cement pouring, do not pound out, port stops up with bolt, and after certain time limit, getting rusty appears in old metal tube, there will be equally seepage.
Utility model content
The problem existing in order to solve above-mentioned prior art, the utility model provides a kind of shuttering supporting pipe.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of shuttering supporting pipe, at least comprises the body with axially extending bore; The two ends of described body respectively have the ring stiffener of at least one evagination; The external surface of described body at least has a shaft orientation reinforcing rib and at least one circumferential reinforcing rib.
As further improvement technical scheme, the shuttering supporting pipe that the utility model provides, the aperture at the through hole both ends of described body is greater than the aperture of body middle part, Kong Yu middle part, both ends has the changeover portion that is tapering between hole, described end hole and described transition sector hole form plug hole, and described shuttering supporting pipe also comprises the plug being connected with described plug hole interference fit.
As further improvement technical scheme, the shuttering supporting pipe that the utility model provides, described plug has the ring-shaped step of at least one evagination.
As further improvement technical scheme, the shuttering supporting pipe that the utility model provides, described plug has groove away from end end.
The beneficial effects of the utility model are: the shuttering supporting pipe that the utility model provides, and reasonable in design, can utilize waste or used plastics to produce, and cost is lower; In use, can stay in concrete, without pounding out, save labour cost, in use modification not, does not produce seepage.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, forms the application's a part, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the main TV structure schematic diagram of embodiment shuttering supporting pipe;
Fig. 2 is the sectional structure schematic diagram of embodiment shuttering supporting pipe;
Fig. 3 is the structural representation of the plug of embodiment shuttering supporting pipe.
The specific embodiment
Shuttering supporting pipe as shown in Figure 1 to Figure 3, body has axially extending bore, the two ends of body 1 respectively have the ring stiffener 5 of four evaginations, and the external surface of body 1 has four shaft orientation reinforcing ribs 3 and three circumferential reinforcing ribs 2, disposed at equal distance between shaft orientation reinforcing rib 3, between circumferential reinforcing rib 2.The aperture at the axially extending bore both ends of described body 1 is greater than the aperture of body middle part, Kong Yu middle part, both ends has the changeover portion that is tapering between hole, described end hole and described transition sector hole form plug hole 4, and shuttering supporting pipe also comprises the plug 6 being connected with described plug hole 4 interference fit.Described plug 6 has the ring-shaped step 7 of two evaginations, and plug 6 has groove 8 away from end end.
Obviously, the utility model is not limited to above preferred embodiment, also can be in the spirit of the utility model claims and manual restriction, carry out conversion and the improvement of various ways, can solve same technical problem, and obtain the technique effect of expection, therefore do not repeat.Those of ordinary skill in the art can be from the disclosed content of the utility model directly or all schemes of associating, as long as within the spirit limiting in claim, also belong to protection domain of the present utility model.
