Abstract
The utility model discloses a split type split bolt which comprises an adjustment rod, conical sleeves and screws. The two ends of the adjustment rod are provided with outer threads respectively, the two ends of the conical sleeves are provided with inner threads respectively, the two ends of the adjustment rod are connected with the small-head ends of the conical sleeves respectively, and the large-head ends of the conical sleeves are connected with the screws. The split type split bolt has the advantages that after a shear wall is completely poured through concrete, the screws and the conical sleeves of the split type split bolt are disassembled, the adjustment rod is left in the wall, through holes can not be generated in the wall, water leakage hidden dangers, caused by uncompacted plugging of screw holes, of the wall are avoided, and the construction working procedures such as screw hole plugging in the later period are reduced; the aim of controlling the thickness of the wall can be achieved by adjusting the lengths of the outer threads at the two ends of the adjustment rod; the conical sleeves and the screws can be repeatedly used, and cost is further saved.
Description
Technical field
The utility model relates to a kind of Split-type opposite-drawing screw rod.
Background technology
At present, in concrete shear force wall body formwork construction, after concreting completes, in body of wall, produce a large amount of screw holes, the later stage need cram screw hole before building by laying bricks or stones and plastering, particularly the screw hole shutoff leakiness at exterior wall position easily causes water leakage of external wall, has large hidden danger of quality.
Utility model content
Technical problem to be solved in the utility model is that provide a kind of for the technical problem existing in above-mentioned prior art can not produce perforation in concrete construction, stops the Split-type opposite-drawing screw rod of the hidden danger of leaking that body of wall causes because of screw hole shutoff leakiness.
The technical scheme that the utility model adopts is: a kind of Split-type opposite-drawing screw rod, it is characterized in that: it comprises that two ends are equipped with externally threaded adjusting rod, conical sleeve, screw rod, the two ends of described conical sleeve are provided with internal thread, the two ends of described adjusting rod are held and are connected with the microcephaly of conical sleeve respectively, and the stub end of each conical sleeve is connected with screw rod.
By technique scheme, described screw rod is T-shaped screw rod.
By technique scheme, described conical sleeve outer wall is set with rubber sheet gasket.
By technique scheme, in the termination of the stub end of conical sleeve, be provided with stepped hole, offer symmetrical radial slot at the end face of the stub end of conical sleeve, this radial slot is communicated with stepped hole.
By technique scheme, corresponding and the stub end of conical sleeve are provided with it arranges mutually and open cone device, and this opens to bore on device and is provided with the trip out parts corresponding with stepped hole and radial slot.
By technique scheme, the described upper end of opening cone device is six-sided nut shape, and lower end is cylinder, is symmetrically arranged with radial projection piece in cylindrical outside, and this cylinder and radial projection piece formation trip out parts.
The obtained beneficial effect of the utility model is: after 1, shear wall concreting completes, by removing screw rod, the conical sleeve of this device, adjusting rod is stayed in body of wall, in body of wall, can not produce like this perforation, stop the hidden danger of leaking that body of wall causes because of screw hole shutoff leakiness, reduce the working procedures such as later stage shutoff screw hole; 2, by regulating the externally threaded length in adjusting rod two ends can reach the object of the thickness of controlling body of wall; 3, conical sleeve, screw rod all can repeat turnover use, have further saved cost; 4, its utility model matching used open cone device simple in structure, easy to operate.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, 2, 3, the structural representation of the detailed description of the invention of its a kind of Split-type opposite-drawing screw rod providing for the utility model, as seen from the figure, it comprises adjusting rod 4, conical sleeve 1, T-shaped screw rod 3, the two ends of described adjusting rod 4 all arrange external screw thread, by the externally threaded length control in its two ends thickness of wall body; Described conical sleeve 1 smooth in appearance, its two ends are provided with internal thread, and described conical sleeve 1 outer wall is set with rubber sheet gasket, in the termination of the stub end of conical sleeve 1, are provided with stepped hole, offer symmetrical radial slot at the end face of its stub end, this radial slot is communicated with stepped hole.Wherein, the two ends of adjusting rod 4 are held and are connected with the microcephaly of conical sleeve 1 respectively, and the stub end of each conical sleeve 1 is connected with screw rod 3.
As shown in Figure 4, before shear wall formwork, first shear wall formwork is configured, and punch in template according to screw rod spacing in template scheme, the little 10mm of this aperture ratio conical sleeve outside diameter, prevents screw hole position spillage; After vertical wall steel bar colligation completes, place Split-type opposite-drawing screw rod according to position of opening, utilize tied silk or rubber band to be temporarily fixed on vertical body of wall horizontal bar, carry out again wall form reinforcing, treat that wall form has closed up and utilize T-shaped screw rod 3 to make template back arris and Split-type opposite-drawing screw rod be connected to form entirety, ensure formwork integral rigidity.
As shown in Figure 5, corresponding to the stub end of conical sleeve be provided with its arrange mutually open cone device 2, shown in Fig. 6,7, the described upper end of opening cone device is six-sided nut shape, lower end is cylinder, be symmetrically arranged with radial projection piece in cylindrical outside, this cylinder and radial projection piece formation trip out parts.As shown in Figure 8, in the time of form removable, first remove T-shaped screw rod 3, the stepped hole that trips out parts insertion conical sleeve and radial slot that cone device 2 is opened in utilization take out body of wall inner conical sleeve 1, after reclaiming cleaning, turnover is used, wherein adjusting rod 4 is stayed in body of wall, stops because of the body of wall that later stage screw hole shutoff leakiness the causes hidden danger of leaking.
