Water absorbent polymer layer 14 is equipped between end plate 13 and bottom surface sections 103.Water absorbent polymer layer 14 and water absorbent polymer The technical effect of ring 121 is identical.Water absorbent polymer in this example refers to the combination comprising polyacrylic absorbent resin powder Object, such as polyacrylamide-Al gel particles, remaining is water-permeable binder.Commonly used in the prior art is to use release agent, But release agent can not prevent access to the solidification in end holes molded part 1, also have part of cement slurry to penetrate into expansion pin 12 Difficulty is caused a departure between locating piece, and the scheme of water absorbent polymer is used perfectly to solve the problems, such as this.
In preferred scheme, fixed on the two sides of the second locating piece 8, the second side form 7 there are two bolt otic placodes 11, compress Bolt 10 passes through bolt otic placode 11 and connect with nut, is equipped between hold-down bolt 10 and the second locating piece 8 for fixing second The clapboard 9 of locating piece 8.Thus structure, convenient for fixing the second locating piece 8.
Embodiment 2:
A kind of construction method using above-mentioned arc service sleeve auxiliary locator, comprising the following steps:
S1, end holes molded part 1 is fixed on the first side form 6 by template connection bolt 2;
Preferably, end plate 13, the bottom surface of end plate 13 and end holes molded part 1 are socketed in the extended tip of the first locating piece 4 It is bonded by water absorbent polymer layer 14.
S2, one end of arc service sleeve 5 is inserted into the first locating piece 4 connecting with end holes molded part 1;
Preferably, expansion pin 12 is inserted into the through-hole of the first locating piece 4, opens extended tip.By arc service sleeve 5 It stoppers.
S3, the end of the extension of the second locating piece 8 is inserted into the second side form 7 and is fixed, by the another of arc service sleeve 5 One end is inserted into the end of the extension of the second locating piece 8;, expansion pin 12 is inserted into the through-hole of the second locating piece 8, makes to extend It opens end.Arc service sleeve 5 is stoppered.
Hold-down bolt 10 passes through bolt otic placode 11 and connect with nut, is inserted between hold-down bolt 10 and the second locating piece 8 Clapboard 9 makes clapboard 9 compress the second locating piece 8.
The positioning and fixation of arc service sleeve 5 before being poured by above step realization prefabricated components.
After S4, molding, casting concrete vibrates, steam curing, after reaching the solidifying phase, first removes clapboard 9, removes pressure Tight bolt 10, takes out expansion pin 12, removes the second locating piece 8.Then the fixture nut on the first side form 6 is removed.Remove first Side form 6 and the second side form 7 catch on the expansion pin at 12 top of expansion pin in end holes molded part 1 by the hook of strip cord Pull ring 122 pulls out expansion pin 12, and due to the effect of water absorbent polymer ring 121, neighbouring cement slurry aquation is insufficient, is easy Separation.And the expansive force of water absorbent polymer ring 121 can also assist separating.Then end holes molded part 1 is removed, it is poly- due to absorbing water Water suction and the expansion effect of nitride layer 14 are closed, the bottom surface sections 103 of end holes molded part 1 are easy to separate with end plate 13, thus complete At the molding of entire curved bolt.Apparatus and method of the present invention, hole forming quality is high, convenient for subsequent curved bolted smoothly complete At.
The above embodiments are only the preferred technical solution of the present invention, and are not construed as limitation of the invention, this Shen Please in embodiment and embodiment in technical characteristic in the absence of conflict, can mutual any combination.Guarantor of the invention The technical solution that range should be recorded with claim is protected, being equal for technical characteristic replaces in the technical solution recorded including claim Changing scheme is protection scope.Equivalent replacement i.e. within this range is improved, also within protection scope of the present invention.
