Abstract
The utility model discloses a kind of tubular connection for building, comprise connector, be enclosed within cutting ferrule outside connector and the shop bolt through cutting ferrule and connector, described connector is made up of two panels inner core, the inwall of inner core is provided with the expanding dowel groove parallel relative to inner core, be provided with the arrow type that symmetry puts in expanding dowel groove and open pin, arrow type opens the position that pin contacts and is provided with arrow type breach, the inwall of inner core is provided with the horizontal groove vertical relative to expanding dowel groove, described shop bolt passes arrow type breach by horizontal groove, avoid and adopt screw and nut, thus reach the object of building pipe docking, structure is simply easy to use, substantially increase operating efficiency.
Description
Technical field
The utility model relates to a kind of engineering construction construction usage material accessory, particularly one tubular connection for building.
Background technology
The tubular connection for building a few days ago used, it is made up of a cross inner core and two semicircle enclosing covers and shop bolt, screw and nut, and its operating principle is through screw nut and closes tight; Two semicircle enclosing covers, enclosing cover clamp one of two building pipes thus reach the object of docking, have employed outer tight operating principle.
For using similar some problem and shortage part existed clasp a few days ago: 1, easy to slip teeth between screw nut.2, extraneous destruction is vulnerable to, because screw thread exposes entirely, easily sticky glutinous by earth, easily get rusty after rainwater drenches, thread of easily damaging in handling process.3, speed is slow, and owing to adopting outer closing lid, need to open closing lid during constructing operation, by closing lid of closing, then one encloses tightened by nut, and speed is very slow, and speed of application is affected.
Utility model content
Technical problem to be solved in the utility model is to provide the tubular connection for building that a kind of structure is simple, increase work efficiency, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the utility model provides following technical scheme: a kind of tubular connection for building, comprise connector, be enclosed within cutting ferrule outside connector and the shop bolt through cutting ferrule and connector, described connector is made up of two panels inner core, the inwall of inner core is provided with the expanding dowel groove parallel relative to inner core, be provided with the arrow type that symmetry puts in expanding dowel groove and open pin, arrow type opens the position that pin contacts and is provided with arrow type breach, the inwall of inner core is provided with the horizontal groove vertical relative to expanding dowel groove, described shop bolt passes arrow type breach by horizontal groove.
Preferably, described inner core is side, two ends is inverted T-shape, and middle part is semicircular cylinder.
Preferably, described cutting ferrule is two ends is trumpet-shaped circular cutting ferrule.
Preferably, described shop bolt is trapezoidal tabular pin.
The beneficial effect of above technical scheme is adopted to be: the tubular connection for building of the utility model structure, the bell-mouthed effect of cutting ferrule, easily pack into building pipe, building pipe box enters horn mouth assigned address, horn mouth cutting ferrule can play the architecture protection pipe when interior pressure is excessive and prevent outer splitting, and cutting ferrule can do the support of inner core simultaneously; The effect of inner core, flechette-type open pin strut two pieces of semicircle inner cores time, it is enough that two pieces of semicircle inner cores can be close to the inner strength uniform strength of building pipe on four sides; Flechette-type open pin and shop bolt with the use of, two panels flechette-type opens pin and squeezes two pieces of semicircle inner cores, two pieces of semicircle inner cores are opened and is close to building pipe inside, fast simple to operate, avoid screw and the nut of background technology employing, thus reaching the object of building pipe docking, structure is simply easy to use, substantially increases operating efficiency.

Detailed description of the invention
A kind of preferred embodiment of a kind of tubular connection for building of the utility model is described in detail below in conjunction with accompanying drawing.
Fig. 1 to Fig. 4 illustrates a kind of tubular connection for building; comprise connector, be enclosed within cutting ferrule 1, shop bolt 3 outside connector; described two panels inner core 2 for side, two ends be inverted T-shape; middle part is semicircular cylinder; the inwall of inner core 2 is provided with the expanding dowel groove 6 parallel relative to inner core; cutting ferrule 1 outside described inner core 2, two is tubaeform being conducive to packing into building pipe and the effect of grinning outside the excessive architecture protection pipe of pressure when two panels inner core 2 opens and do the effect of inner core 2 support.Described shop bolt 3 is trapezoidal tabular pin 3, innercore sidewall is provided with horizontal groove 5, and shop bolt 3 is thrown into and the arrow type of two panels inner core 2 li can be opened pin and squeeze, and two panels inner core 2 is opened simultaneously, two panels inner core 2 is close to building inside pipe wall, thus realizes two building pipe docking.
The tubular connection for building of the utility model structure, the bell-mouthed effect of cutting ferrule 1, easily packs into building pipe, and building pipe box enters horn mouth assigned address, horn mouth cutting ferrule 1 can play the architecture protection pipe when interior pressure is excessive and prevent outer grinning, and cutting ferrule 1 can do the support of inner core 2 simultaneously; The effect of inner core 2, flechette-type open pin 4 strut two pieces of semicircle inner cores 2 time, it is enough that two pieces of semicircle inner cores 2 can be close to the inner strength uniform strength of building pipe on four sides; Flechette-type open pin 4 and shop bolt 3 with the use of, two panels flechette-type opens pin 4 and squeezes two pieces of semicircle inner cores 2, two pieces of semicircle inner cores 2 are opened and is close to building pipe inside, fast simple to operate, avoid screw and the nut of background technology employing, thus reaching the object of building pipe docking, structure is simply easy to use, substantially increases operating efficiency.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
