Further, it is provided with non-slip texture on the outer wall of the hand block.
Through the above technical solutions, further increase the friction between hand block and the user's palm using non-slip texture
Power, convenient for the gripping of user.
Further, the profiled section is in round table-like setting, and outer diameter is gradually reduced along the direction far from the boss section.
Through the above technical solutions, since the profiled section of embedded concrete component is up big and down small, so as to the outlet of preformed hole
Aperture is in magnifying state, convenient for after the concrete has set extracting sleeve out from concrete.
Further, the two opposite sides on the boss section top are respectively arranged with convenient for hand-held lifting lug.
Through the above technical solutions, in pulling off sleeves, lifting lug facilitates staff to hold, and obtains the power of staff
It plays to greatest extent.
Compared with prior art, the beneficial effects of the utility model are：
(1) pore-forming templates are set by the mold restocking in concrete component, and pass through magnet to be threaded with screw rod
Sleeve is mounted on pore-forming templates, so as to which easily sleeve can be inserted into concrete component by pore-forming templates, also, due to
Sleeve is flexibly connected with pore-forming templates, will to adapt to the molding of the preformed hole of different location so as to facilitate the position of regulating sleeve
It asks；
(2) by the way that sleeve is divided into boss section and profiled section, boss section protrusion concrete component, pore-forming templates and coagulation
Native component separation is conducive to improve the solidification rate of concrete component；Profiled section in round table-like, convenient for by sleeve from concrete structure
It is extracted out in part；
(3) by setting lifting lug on sleeve, convenient for users to sleeve is extracted out from concrete component, sleeve is improved
Removal efficiency.
