[0021] The utility model provides a kind of lock catch formula reinforcing end mould for prefabricated column as Figs. 1-3 As shown in figure 1, it comprises:

[0022] End mould main body 100, the periphery of end mould main body 100 is equipped with reinforcing outlet 101, reinforcing outlet 101 is equipped with reinforcing 102 in penetration, the both sides of reinforcing outlet 101 are equipped with threaded hole 103, end mould main body 100 includes the upper end mould 104 of being arranged at the top end of prefabricated column and the lower end mould 105 of being arranged at the bottom end of prefabricated column;

[0023] Lock catch ring 200, lock catch ring 200 is arranged at the outer side of end mould main body 100, lock catch ring 200 includes lower half ring 201, upper half ring 202 hinged with lower half ring 201 and ear plate 203 fixed at the both sides of lower half ring 201, two ear plates 203 are set up with two threaded holes 103 one by one and are fixedly connected by screw.

[0024] Exemplarily, referring to Figs. 1-2 As shown in figure 1, upper end mould 104 and lower end mould 105 are rectangular structure, the center of the inner side of lower end mould 105 is equipped with shear-resistant boss 106, shear-resistant boss 106 uses integral molding design with lower end mould 105.

[0025] In the technical scheme, by setting shear-resistant boss 106, shear key groove can be formed at the bottom of prefabricated column after concrete pouring and solidification, which resists column bottom shear force and prevents slip between column bottom plate and foundation concrete top surface.

[0026] Exemplarily, referring to Fig. 1 As shown in figure 1, shear-resistant boss 106 is isosceles ladder structure, and the height of shear-resistant boss 106 is 30-50mm.

[0027] In the technical scheme, by setting the height of shear-resistant boss 106 as 30-50mm, the depth of shear key groove is also 30-50mm, which can effectively enhance the bearing capacity and stability of prefabricated column structure.

[0028] Exemplarily, referring to Figs. 2-3As shown, the center axis of the out-joint opening 101, the out-joint 102 and the locking circular ring 200 coincide, and the inner wall of the locking circular ring 200 is in close contact with the outer wall of the out-joint 102.

[0029] In the technical solution, when the locking circular ring 200 is closed, the out-joint 102 can be wrapped, and the gap between the out-joint 102 and the out-joint opening 101 can be closed, effectively solving the problem of slurry leakage, and being conducive to improving the appearance quality and structural strength of the prefabricated column.

[0030] For example, referring to Figs. 2-3 As shown, the center axis of the out-joint opening 101, the out-joint 102, the threaded hole 103 and the locking circular ring 200 coincide.

[0031] In the technical solution, when the inner wall of the lower half circular ring 201 is in close contact with the bottom of the out-joint 102, the upper half circular ring 202 can be buckled with the lower half circular ring 201, and the inner wall of the upper half circular ring 202 is in close contact with the bottom of the out-joint 102.

[0032] For example, referring to Fig. 1 As shown, the top of the upper end mold 104 movably sleeved with a lifting ring 107.

[0033] In the technical solution, when the concrete pouring is completed and solidified, the upper end mold 104 is removed, and at this time, the lifting ring 107 is left on the top of the prefabricated column, which is convenient for the transportation of the prefabricated column.

[0034] For example, referring to Fig. 1 As shown, the top of the lower end mold 105 is fixedly connected with a grouting exhaust pipe 108.

[0035] In the technical solution, the gas generated during the concrete pouring process can be easily discharged.

[0036] Working principle: when the locking type out-joint end mold for prefabricated column is used, first, the end mold body 100 is fixed at both ends of the prefabricated column side mold, and then the ear plate 203 on the locking circular ring 200 is fixed on the end mold body 100 through a screw, at this time, the lower half circular ring 201 is in close contact with the bottom of the out-joint 102, and then the upper half circular ring 202 is buckled with the lower half circular ring 201, so that the upper half circular ring 202 is in close contact with the top of the out-joint 102, that is, the installation of the end mold body 100 is completed. The locking type out-joint end mold for prefabricated column is advanced in design, compact in structure and convenient to use. By fixing the locking circular ring 200 on the outside of the out-joint opening 101, the inner wall of the locking circular ring 200 is in close contact with the outer wall of the out-joint 102, which can not only seal the gap between the out-joint 102 and the out-joint opening 101 to avoid the problem of slurry leakage during pouring of concrete, but also support and limit the out-joint 102 to avoid the position of the out-joint 102 from being deviated, and thus avoid the friction between the out-joint 102 and the end mold body 100, facilitating the removal of the mold.

[0037] It should be pointed out finally that: the above only for the preferred embodiments of the utility model have, and do not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. that is made within the spirit and principles of the utility model, should be included in the protection scope of the utility model.
