The outer side surfaces of the longitudinal I-shaped steel columns corresponding to the two end surfaces of the transverse I-shaped steel columns are provided with fixing lifting lugs, the upper parts of the fixing lifting lugs are higher than the upper end surfaces of the longitudinal I-shaped steel columns, and the centers of the upper parts of the fixing lifting lugs are provided with fixing through holes.
The inner periphery of the self-anchored steel frame shaped like a Chinese character 'jing' is square. The fixing pins are made of ribbed steel bars with the diameter of 32mm, the length of each fixing pin is 15cm, the lower end of each fixing pin extends out of the lower end face of the triangular steel plate by 5cm, and the upper end of each fixing pin extends out of the upper end face of the triangular steel plate by 8 cm. The triangular steel plate is an isosceles right-angle triangular steel plate with a right-angle side length of 0.3m and a thickness of 2 cm. The side length of the inner peripheral wall of the self-anchored steel frame is larger than the diameter of the steel reinforcement cage.
Above-mentioned structural design has reached the utility model discloses a purpose.
The utility model discloses can interim location pile foundation steel reinforcement cage to improve pile foundation steel reinforcement cage's installation rate and efficiency of construction, reduce construction safety risk, have simple structure, cost of manufacture low and excellent in use effect's advantage.

Detailed Description
As shown in fig. 1 to 3, a temporary fixing device for a bridge pile foundation reinforcement cage is composed of fixing lugs 4. Two ends of two transverse H-shaped steel columns 2 which are arranged side by side at intervals are fixed into a whole through a longitudinal H-shaped steel column 5 by welding to form a self-anchored cross steel frame. The inner periphery of the self-anchored steel frame shaped like a Chinese character 'jing' is square.
And a triangular steel plate 3 is welded at the included angle between the upper end surfaces of the transverse I-shaped steel column and the longitudinal I-shaped steel column. The triangular steel plate is an isosceles right-angle triangular steel plate with a right-angle side length of 0.3m and a thickness of 2 cm. The central point of the upper end surface of each triangular steel plate is provided with a through hole respectively. The lower part of the fixing pin 1 passes through the through hole, and the corresponding fixing pin peripheral wall and the through hole are fixed into a whole through welding. The fixing pins are made of ribbed steel bars with the diameter of 32mm, the length of each fixing pin is 15cm, the lower end of each fixing pin extends out of the lower end face of the triangular steel plate by 5cm, and the upper end of each fixing pin extends out of the upper end face of the triangular steel plate by 8 cm.
The outer side surfaces of the longitudinal I-shaped steel columns corresponding to the two end surfaces of the transverse I-shaped steel columns are provided with fixing lifting lugs, the upper parts of the fixing lifting lugs are higher than the upper end surfaces of the longitudinal I-shaped steel columns, and the centers of the upper parts of the fixing lifting lugs are provided with fixing through holes 6. The fixed lifting lugs are composed of steel plates with the length of 0.3m, the width of 0.2m and the thickness of 2cm, and each fixed lifting lug is provided with a fixed through hole with the diameter of 3 cm.
The side length of the inner peripheral wall of the self-anchored steel frame is larger than the diameter of the steel reinforcement cage.
During the use, will the utility model discloses pass through the fixed lug installation with the crane and fix on highway pier pile foundation hole's upper end subaerial, from the axis coincidence of anchor formula groined type steelframe and highway pier pile foundation hole. Pass single pile foundation steel reinforcement cage's one end the utility model discloses a well week portion gets into in the highway pier pile foundation hole, evenly arranges four wire rope's one end through buckle (having had the product) and fixes on this single pile foundation steel reinforcement cage's reinforcement ring, and each wire rope's the other end passes through the buckle to be fixed the utility model discloses on the fixation pin of corresponding portion, borrow the lower extreme of wearing the reinforcement ring that thick stick (the bar steel that can support steel reinforcement cage) passed this single pile foundation steel reinforcement cage at the scene again, the up end at horizontal or vertical I-steel column is held in both ends top of wearing the thick stick, carries out interim fixed to the steel reinforcement cage that has installed in the hole. After the upper section of the steel reinforcement cage is installed, the single pile foundation steel reinforcement cage is integrally lifted, the penetrating rod is pulled out, four steel wire ropes are dismounted, and then the single steel reinforcement cage is integrally lowered.
Obviously, the upper portion of single pile foundation steel reinforcement cage can receive four wire rope's pulling force, and the center of the directional highway pier pile foundation hole of four pulling force direction slopes, can decompose into four horizontal direction's component force of these four pulling forces with four vertical decurrent component forces, and construction platform is directly given to vertical decurrent component force, because that four fixed pins constitute is the square, consequently four horizontal direction's component force can two liang offset, consequently with the help of the utility model discloses only need during the interim fixed steel reinforcement cage to put on construction platform from anchor type # -shaped steel frame can, the horizontal direction need not consider any fixed measure.
In a word, the utility model discloses can interim location pile foundation steel reinforcement cage to improve pile foundation steel reinforcement cage's installation rate and efficiency of construction, reduce construction safety risk, have simple structure, cost of manufacture low and excellent in use effect's advantage. Can be popularized and used.
