Description
Technical Field
The utility model belongs to the technical field of bridge construction, and particularly relates to a pile foundation steel reinforcement framework manhole accurate positioning device.
Background
When the highway bridge pile foundation steel bar framework is erected in the manhole, the eccentricity phenomenon can occur under the influence of factors such as operating level or local deformation of steel pile casing embedding, and the like, and then the steel bar framework protective layer after the manhole is too large or too small; the bridge pile columns are generally connected through the tie beams, the deviation between the center of the column and the center of the pile is required to be within 5cm, and therefore the accuracy of the hole entering of the steel reinforcement framework needs to be strictly controlled, and the thickness of the protective layer can be ensured to meet the requirements.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problems, the utility model aims to provide an accurate positioning device for a pile foundation steel reinforcement framework access hole.
The utility model adopts the following technical scheme for achieving the purpose:
a pile foundation steel reinforcement framework manhole accurate positioning device is provided with two rectangular steel plates which are arranged in parallel; the two rectangular steel plates are connected through equal-edge angle steel perpendicular to the rectangular steel plates; the two equal-edge angle steels are symmetrically arranged; two ends of each equilateral angle steel are respectively connected with the two rectangular steel plates; the rectangular steel plate and the equilateral angle steel are both provided with strip-shaped connecting holes, and the strip-shaped connecting holes form adjusting holes; the two rectangular steel plates and the two equal-side angle steels are connected into a whole to form a rectangular frame structure with adjustable size; the two equal-edge angle steels are respectively and fixedly connected with a semicircular clamp; the two semicircular clamps act along with the corresponding equal-edge angle steel to form an adjustable positioning device; a cavity for placing a reinforcement cage is formed between the two semicircular clamps.
The rectangular steel plate is provided with scale marks.
The equilateral angle steel is provided with scale marks.
According to the accurate positioning device for the pile foundation steel reinforcement framework access hole, the technical scheme is adopted, and accurate positioning adjustment is achieved through movement between the equilateral angle steel and the rectangular steel plate, so that the requirement of the thickness of the protective layer is met.

Detailed Description
The utility model is described in detail with reference to the accompanying drawings and specific embodiments:
as shown in fig. 1 and 2, the device for accurately positioning the hole into the steel reinforcement cage of the pile foundation is provided with two rectangular steel plates 1 which are arranged in parallel; the two rectangular steel plates 1 are connected through equal-edge angle steel 2 perpendicular to the rectangular steel plates; the two equal-edge angle steels 2 are symmetrically arranged; two ends of each equilateral angle steel 2 are respectively connected with the two rectangular steel plates 1; the rectangular steel plate and the equilateral angle steel are both provided with strip-shaped connecting holes 6, and the strip-shaped connecting holes 6 form adjusting holes; the two rectangular steel plates 1 and the two equilateral angle steels 2 are connected into a whole to form a rectangular frame structure with adjustable size, and the adjusted equilateral angle steels and the rectangular steel plates are fixedly connected and positioned through fixing bolts and gaskets 3; the two equal-edge angle steels are respectively and fixedly connected with a semicircular clamp 4; the two semicircular clamps 4 act along with the corresponding equal-edge angle steel 2 to form an adjustable positioning device; a cavity for placing a reinforcement cage is formed between the two semicircular clamps.
The rectangular steel plate is provided with scale marks.
The equilateral angle steel is provided with scale marks.
When the positioning device works, the cross line is pulled to find out the center point of a pile foundation, and steel brazes 5 are arranged around the center point for fixing the whole positioning device; the steel reinforcement cage is properly pulled open in 4 directions, namely, the front direction, the rear direction, the left direction and the right direction, the steel reinforcement cage is installed into the hole by a crane, and the top of the steel reinforcement cage is temporarily fixed at the top of the steel casing through the carrying pole beam 7 to wait for being connected with a lower section of the steel reinforcement cage. According to the radius scales of the surfaces of the rectangular steel plate and the equal-edge angle steel, the accurate positioning is realized by moving the adjusting hole by using the 3 fixing bolt and the gasket according to the radius scales.
