The invention discloses an ultra-high-turnover-rate and casing-pipe-penetration-free opposite-pull fixing structure. The fixing structure comprises a first rod body, a first fixing part and a second fixing part, wherein the first rod body is located between two templates after being mounted; the outer diameter of the cross section of the first rod body is gradually reduced in the insertion direction; the first fixing part is positioned outside one of the templates and is connected with the small-diameter end of the first rod body; and the second fixing part is positioned outside the other template and is connected with the large-diameter end of the first rod body. The first fixing part connected with the small-diameter end of the first rod body is knocked, and under the effect of the gradient of the first rod body, the first rod body and the first fixing part can be pulled out easily by dragging the second fixing part from one side of the template where the second fixing part is located, so that the ultrahigh turnover rate is achieved, and the casing pipe consumption of traditional split bolts can be greatly reduced. Therefore, the structure is simple and convenient to use, a large number of casing pipes can be saved, the construction cost is effectively controlled, and the structure has extremely high practicability.
Description
technical field [0001] The invention relates to the technical field of fixing the formwork of cast-in-situ beams, walls or columns, in particular to a double-tension fixing structure with an ultra-high turnover rate without piercing sleeves. Background technique [0002] Before concrete structures such as beams, walls or columns are poured, a formwork needs to be set up to form the area to be poured, and the formwork is usually fixed by pull bolts. In order to facilitate taking out the screw rod after the pouring is completed, the usual operation is to put a sleeve (generally a PVC pipe) on the outside of the screw rod. After the pouring is completed, the screw rod is pulled out, and the sleeve pipe is left in the concrete structure. Such an operation wastes a lot of casing resources. Contents of the invention [0003] The main purpose of the present invention is to provide a double pull fixing structure with convenient installation, good template fixing effect, easy remo...
