Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
As shown in Figure 1, a kind of plug-in syndeton connected for prefabricated units, comprise a connection-peg 1 and an attaching nut 2, described attaching nut 2 one end has the Access Division 21 outstanding to the direction of axis line of attaching nut 2, attaching nut 2 other end is uncovered structure and has internal thread in attaching nut 2, in inverted round stage taper bottom described Access Division 21, described connection-peg 1 one end has external screw thread, the other end comprises several circumferentially evenly distributed card columns 11, the end of described card column 11 have in expand shape clamping joint 12 and the upper surface of clamping joint 12 near Access Division 21 has the wedge 13 matched with surface, Access Division 21, described wedge 13 and the surface of Access Division 21 match thus make card column 11 and attaching nut 2 form snap-fit engagement.
Shown in composition graphs 3 and Fig. 4, top, Access Division 21 has the interface 22 in inverted round stage taper, described attaching nut 2 has in polygonal joint pin 23, and have gap 14 between every two adjacent card columns 11, the center of clamping joint 12 has interface channel 15.
Attaching nut 2 is bolted with connecting bolt 3 away from one end of Access Division 21, and described connecting bolt 3 is provided with alignment pin 31 and alignment pin 31 to be inserted in interface channel 15 and to make card column 11 and alignment pin 31 close contact.The hand of spiral of connecting bolt 3 two ends is contrary.Connecting bolt 3 has in polygonal fastener 32, the instruments such as spanner fastener 41 cooperation can be used for the bolt 3 that is rotatably connected, and the hand of spiral being positioned at fastener 32 both sides is contrary.Alignment pin 31 end winding support has location to expand pin 33, and location is expanded the size of pin 33 and is greater than the aperture of interface channel 15, thus can strut card column 11 pairs of card columns 11 and play positioning action.
Connection-peg 1 and connecting bolt 3 are bolted with a bar assembly 5 respectively, in the pre-buried prefabricated units 100 to needing to connect of bar assembly 5.
The collar nut 52 that bar assembly 5 comprises barred body 51 and is connected with the end of barred body 51, described collar nut 52 has internal thread, and described collar nut 52 is spirally connected fixing with connecting bolt 3 or connection-peg 1.
Barred body 51 is inner and along the air flow channel 53 being axially arranged with hollow of barred body 51, described barred body 51 outer wall is provided with the solarization air cap 54 be communicated with air flow channel 53, described air flow channel 53 is communicated with collar nut 52, and the sidewall of described collar nut 52 is provided with at least one grout hole 55.Barred body 51 is one-body molded with collar nut 52, or described barred body 51 and collar nut 52 snap-fit engagement.
As shown in Figure 5, barred body 51 is one-body molded with collar nut 52, as shown in Figure 6 and Figure 7, and barred body 51 and collar nut 52 snap-fit engagement, specifically, the end of barred body 51 to expand in the portion of expanding 56, and this expands portion 56 and can realize snap-fit engagement with collar nut 52, thus the on-fixed realized between collar nut 52 with barred body 51 is connected, barred body 51 can the affixed collar nut 52 in one end, other end clamping collar nut 52, or barred body 51 two ends can clamping collar nut 52.
Operating principle of the present invention is: as shown in Figure 1, bar assembly 5 is embedded in the prefabricated units 100 of two opposite needs connections respectively in advance, prefabricated units 100 can be bodies of wall, cement block, pipeline, pile tube etc., the card column 11 of connection-peg 1 is inserted into interface 22, Access Division 21 expands after entering into Access Division 21 after drawing in
Shown in composition graphs 2, now, be rotationally connected nut 2 or connecting bolt 3, connecting bolt 3 can be adjusted and enter into length in attaching nut 2, thus adjust the length of whole connector, also the length between two prefabricated units 100 needing to connect can just be adjusted, or, be rotationally connected bolt 3 and adjust the length that connecting bolt 3 enters into collar nut 52, equally also can adjust the length of whole connector, but the distance of this adjustment is subject to the impact of collar nut 52 and connecting bolt 3 fitness, and the distance of adjustment is limited.When attaching nut 2 arrives correct position, wedge 13 and Access Division 21 snap-fit engagement, now location is expanded pin 33 pairs of card columns 11 and is also played the effect of strutting, and plays location, connection-peg 1 and attaching nut 2 snap-fit engagement to card column 11.
When in the prefabricated units 100 that bar assembly 5 is embedded to cement paste, as prefabricated units 100 ot-yet-hardened, from collar nut 52, air can be passed into air flow channel 53, and blow out from solarization air cap 54, sclerosis is accelerated to not solidified prefabricated units 100.Collar nut 52 outer wall is provided with the grout hole 55 being communicated with collar nut 52 inside, it is inner that cement paste can enter into collar nut 52 from grout hole 55, when cement slurry sets, connection-peg 1 and/or the connecting bolt 3 of butt joint nut 52 inside play fixation, thus improve the structural strength of whole connector.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
Although more employ connection-peg 1 herein, card column 11, clamping joint 12, wedge 13, gap 14, interface channel 15, attaching nut 2, Access Division 21, interface 22, connecting bolt 3, alignment pin 31, fastener 32, location expand pin 33, bar assembly 5, barred body 51, collar nut 52, air flow channel 53, solarization air cap 54, grout hole 55, the term such as portion 56, prefabricated units 100 that expands, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present invention more easily; The restriction that they are construed to any one additional is all contrary with spirit of the present invention.
