Description

Detachable rectangular pier stud slurry leakage preventing device Technical Field The utility model relates to the field of bridge pier column construction, in particular to a detachable rectangular pier column leakage-proof device. Background The rectangular pier column is frequently used in a bridge high pier by virtue of good bending resistance, the template is subjected to repeated collision in the construction process, the phenomenon of uneven surface exists, the flatness of the upper edge and the lower edge of the template is inconsistent, the vibrating rod interferes with the template to deform during concrete vibrating, and the concrete slurry is a liquid material without holes. Under the condition that the template is not tightly attached to the pier stud, bottom slurry leakage is easy to occur during concrete pouring, and root rot and honeycomb pitting phenomena can be caused if severe, so that adverse effects are caused on structural appearance and durability. In the field use, the double faced adhesive tape and the foam rubber plug are adopted between the template and the pier stud, the double faced adhesive tape cannot be filled with the rugged template due to single thickness, the foam rubber cannot be controlled due to the depth of the gap between the template and the pier stud, the phenomenon of poor appearance quality after the foam rubber is intruded into a main body or removed from the mould is easily caused, and sometimes the foam rubber drops due to construction interference after hardening, so that the slurry leakage phenomenon is caused. Therefore, a detachable rectangular pier stud leakage prevention device is needed to solve the above problems. Disclosure of utility model In order to solve the technical problems, the utility model adopts the following technical scheme: The detachable rectangular pier column slurry leakage preventing device is arranged at the lower end of the template and is a slurry leakage preventing structure; The slurry leakage preventing structure comprises a fixing part and an elastic unit, wherein the fixing part is provided with a groove, the elastic unit is partially accommodated in the groove, and the fixing part is connected with the lower end of the template. Preferably, the fixed part and the corresponding position of the template are provided with drilling holes, the first bolt is matched with the nut to fix the fixed part and the template, and the elastic unit is detachably accommodated in the groove. Preferably, the top of the fixing part is provided with a through groove with a convex section, the screw heads of the first bolts are movably arranged in the through groove, the template is provided with a plurality of first fixing holes, the screw rods of the first bolts penetrate through the corresponding first fixing holes and are in threaded connection with the corresponding fixing nuts, and the fixing part is fixedly connected with the lower end of the corresponding template by screwing the fixing nuts. Preferably, the slurry leakage preventing structure further comprises a plurality of second fixing portions with groove-shaped sections, second connecting holes are formed in two ends of each second fixing portion, a plurality of third connecting holes penetrate through the fixing portions and the elastic units, a screw rod of each second bolt penetrates through the second connecting holes in the lower ends of the second fixing portions, the third connecting holes and the second connecting holes in the upper ends of the second fixing portions sequentially from the bottom, two second fixing nuts are connected to the second bolts in a threaded mode, one second fixing nut is located on the top face of each second fixing portion, and the other second fixing nut is located on the face, opposite to the top face of each second fixing portion.
