Detailed description of the invention
The utility model provides a kind of two-part split bolt, for making the purpose of this utility model, technical scheme and effect clearly, clearly, further describes the utility model referring to accompanying drawing examples.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to shown in Fig. 1, the two-part split bolt that the utility model provides, comprise the bolt sleeve 1 be embedded on prefabricated units 8, the first screw rod 2 be connected with described bolt sleeve 1, the second screw rod 6 of removably connecting with described first screw rod 2, wherein the first screw rod 2 for drawknot prefabricated units 8 and site concrete 9, second screw rod 6 for drawknot site concrete 9 and template 10; Described second screw rod 6 length direction is also arranged with a sleeve pipe 5, for what described second screw rod 6 and described site concrete 9 are isolated.
Concrete, described first screw rod 2 realizes dismountable connected mode with described second screw rod 6, and by arranging a branch sleeve 4 in one end of described second screw rod 6, this branch sleeve 4 is arranged on one end that described second screw rod 6 is connected with the first screw rod 2.Described branch sleeve 4 is connected by welding manner with described second screw rod 6; Be provided with internal thread in one end that described branch sleeve 4 is connected with described first screw rod 2, the link of described first screw rod 2 is provided with external screw thread, and described branch sleeve 4 can realize being threaded with described first screw rod 2.When dismantling the connection between the first screw rod 2 and the second screw rod 6, only need rotate the second screw rod 6 can disassemble coupling nut 7 and the first screw rod 2.Certain, also the contrary internal thread of rotation direction can be set respectively at branch sleeve 4 two ends, the link of the first screw rod 2 and the second screw rod 6 is set to external screw thread suitable with the reverse thread in described branch sleeve 4 respectively, and the external screw thread namely on described first screw rod 2 and the external thread rotary on the second screw rod 6 are on the contrary.Specifically when dismounting first screw rod 2 and the second screw rod 6, rotate the second screw rod 6, now turning to of the second screw rod 6 is locking state with coupling nut 7, and coupling nut 7 and the first screw rod 2 are then disassembly status.
Further, as specific embodiment of the utility model, also described first screw rod 2 directly can be threaded with described second screw rod 6.Concrete, the external diameter that can arrange described first screw rod 2 and the second screw rod 6 link is greater than the external diameter of described second screw rod 6 link, and internal thread hole is set in the link external diameter of the first screw rod 2, second screw rod 6 link arranges external screw thread, to reach the first screw rod 2 and the interconnective object of the second screw rod 6.The other end of described second screw rod 6 adopts nut 7 to be fixed in template 10, can complete the drawknot between the template of wall form medial and lateral, bear concrete lateral pressure and other loads.
When the utility model specifically uses, can consult shown in Fig. 2 and Fig. 3, Fig. 2 upper end is prefabricated units 8, two bolt sleeves 1 are embedded with in prefabricated units 8, bolt sleeve 1 is connected with the first screw rod 2 bolt, the other end of the first screw rod 2 is connected with the second screw rod 6 with coupling nut 7, and then described second screw rod 6 arranges a sleeve pipe 5, this sleeve pipe 5 is preferably pvc pipe, and at this pvc pipe, the blocking bar 3 for preventing concrete from entering described PVC sleeve pipe 5 is set near first screw rod 2 one end, described blocking bar 3 should be positioned at the screw tip of the first screw rod 2, accomplish to prevent concrete coagulation from living splicing sleeve 5.The other end of described second screw rod 6 adopts nut 7 to be fixed in template 10.As shown in Figure 2 vertical, the both sides of prefabricated units 8 are provided with two-part split bolt equally.Same, transversely also two-part split bolt should be set what connect prefabricated units 8 and site concrete 9.When fluid concrete, after connection completes two-part split bolt, carry out cast-in-place note, make site concrete 9 shaping.After site concrete 9 is shaping, pull down template 10, rotate the second screw rod 6 and coupling nut 7 is separated with the first screw rod 2, take out the second screw rod 6 and coupling nut 7 to recycle, the first screw rod 2 is stayed in cast component, connect prefabricated units 8 and site concrete 9.
In sum, two-part split bolt provided by the utility model, owing to have employed pulling structure, bolt part is divided into two sections, reserved one section of bolt connects prefabricated units 8 and site concrete 9, can ensure that prefabricated units 8 are connected with the reliable of site concrete 9, when can build as site concrete 9 again, template 10 lacing wire is used.And the second screw rod 6 and coupling nut 7 can be recycled, need not whole split bolt all be stayed in site concrete 9, then split bolt redundance be cut away, simplify the production of prefabricated units 8 and the construction at scene.
