Description
Technical Field
The utility model relates to a steel reinforcement cage processing technology field of bridge pile foundation and pier stud, concretely relates to support device in adjustable steel reinforcement cage for preventing steel reinforcement cage warp.
Background
Pier stud and pile foundation steel reinforcement cage include fore-and-aft main muscle and hoop muscle that encircles. After the reinforcement cage is processed, an inner support is usually arranged in the reinforcement cage in order to prevent the reinforcement cage from being extruded and deformed in the transportation process. The general inner support is that a steel bar is used as a support bar, two ends of the support bar are welded with stirrups in a steel reinforcement cage, and the support bar is cut off before the steel reinforcement cage is installed. A large amount of working hours are consumed in the construction process of the traditional internal support mode, and the situation that the effective support cannot be achieved due to the fact that errors exist in the length of the support rod is frequent.
Disclosure of Invention
The utility model aims at supporting the not enough of existence in the current welded type steel reinforcement cage, provide an adjustable steel reinforcement cage internal support device, support the installation efficiency of construction in improving to guarantee the supporting effect.
The technical scheme of the utility model as follows:
the utility model provides an adjustable support arrangement in steel reinforcement cage which characterized in that: the telescopic type steel bar fixing device comprises 3 telescopic type supporting bars, wherein each supporting bar comprises an adjusting bar and two fixing bars, threads with certain lengths are arranged at two ends of the adjusting bar respectively, a rotating handle is arranged in the middle of the adjusting bar, each fixing bar comprises two parallel fixing steel bars, a threaded sleeve is welded between one ends of the two fixing steel bars, a hinge nut is welded between the other ends of the two fixing steel bars, the axial direction of the threaded sleeve is parallel to the axial direction of the fixing steel bars, the axial direction of the hinge nut is perpendicular to the axial direction of the fixing steel bars, and two ends of the adjusting bar are in threaded; the 3 support rods are arranged according to 3 sides of a triangle, the axes of the hinged nuts at the end parts of the two adjacent fixing rods are on the same straight line, and a bolt is screwed in the two hinged nuts or a pin shaft is inserted in the two hinged nuts.
The utility model adopts a telescopic structure, the whole body is triangular, so that the size of the inner support is adjustable, the structure is stable, and the supporting effect on the reinforcement cage can be ensured; the installation process has no welding link, the installation and disassembly speed is high, and the construction efficiency is high; the detachable steel plate can be repeatedly used, and the construction cost can be saved.
The utility model discloses also can be used to the support of pile foundation dado template.

Detailed Description
As shown in fig. 1, 2 and 3, the utility model discloses a 3 telescopic supporting rods, each supporting rod includes an adjusting rod 1 and two dead levers, the both ends of adjusting rod 1 are equipped with the screw thread of certain length respectively, the centre is equipped with turning handle 2, each dead lever includes two parallel fixed steel bars 3, weld a thread bush 4 between two fixed steel bar 3 one ends, weld a hinged nut 5 between the other end, the axial of thread bush 4 is parallel with the axial of fixed steel bar 3, the axial of hinged nut 5 is perpendicular with the axial of fixed steel bar 3, the both ends of adjusting rod 1 respectively with the thread bush 4 spiro union on two dead levers; the 3 support rods are arranged according to 3 sides of a triangle, the axes of the hinged nuts 5 at the end parts of two adjacent fixing rods are on the same straight line, and a bolt 6 is screwed in the two hinged nuts or a pin shaft is inserted in the two hinged nuts to hinge the end parts of the two fixing rods.
As shown in fig. 4, will in the steel reinforcement cage the utility model discloses a 3 angles support respectively on steel reinforcement cage ring is to stirrup 7, adjust pole 1 through rotating 3, adjust the length of each bracing piece, make 3 angles of interior support arrangement top tight annular stirrup, realize the firm support to steel reinforcement cage. When the support rod is disassembled, the adjusting rod is rotated reversely, so that the length of the support rod is shortened, and the inner support device can be disassembled.
