In order to solve the technical problems, the utility model adopts the following technical scheme:
the utility model provides a pile foundation steel reinforcement cage post footpath strutting arrangement, includes the screw rod, and screw rod one end is fixed with the jacking, and the jacking is jacked on the steel reinforcement cage, and the screw rod other end and adjusting nut threaded connection, connecting pipe both ends cup joint with a screw rod respectively and through adjusting nut spacing.
The end of the adjusting nut is provided with a limit groove, and two ends of the connecting pipe are propped in the limit groove of the adjusting nut.
The side wall of the adjusting nut is provided with a handle or is a hexagonal prism surface.
The connecting pipes are two groups, and the two groups of connecting pipes are fixedly connected into a whole through bolts.
The jacking is an arc-shaped rod matched with the inner wall of the reinforcement cage.
The utility model relates to a pile foundation reinforcement cage column diameter supporting device, which has the following technical effects:
1) By installing the supporting device between the reinforcement rings of the reinforcement cage, the problem of small diameter in the processing process of the reinforcement cage can be avoided, the processing precision can be improved, and the processing quality can be ensured.
2) The adjustable jacking is adopted, the adjusting nut is installed and removed, the rotation is completed, the operation is simple, the turnover and the recycling of the supporting device are realized, and the labor and the material cost are saved.
3) The adjusting nut is used for adjusting, the screw rod is sleeved with the connecting pipe, the threaded sleeve is arranged in the connecting pipe, the adjusting nut belongs to a manufacturer shaping product, the connecting pipe is a common welded steel pipe, and the processing and the manufacturing are simple. Because the two groups of connecting pipes are connected together, the overall shape of the reinforcement cage can be finely adjusted by rotating the handle on the side wall of the adjusting nut.
Drawings
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
fig. 1 is a schematic view of the installation of the present utility model.
Fig. 2 is a schematic view of a partial structure of the present utility model.
In the figure: jacking 1, screw rod 2, adjusting nut 3, spacing groove 3.1, connecting pipe 4, bolt 5, steel reinforcement cage 6, stirrup 6.1, indulge muscle 6.2.
Detailed Description
As shown in fig. 1-2, a pile foundation reinforcement cage column diameter supporting device comprises a screw rod 2, wherein a jacking 1 is welded at one end of the screw rod 2, the jacking 1 is jacked on the inner wall of a reinforcement cage 6, the other end of the screw rod 2 is in threaded connection with an adjusting nut 3, and two ends of a connecting pipe 4 are respectively sleeved with the screw rod 2 and limited through the adjusting nut 3. During assembly, the jacking 1 and the screw rod 2 are welded together, the screw rod 2 is screwed with the adjusting nut 3, the screw rod 2 is sleeved at two ends of the connecting pipe 4, part of the screw rod 2 extends into the connecting pipe 4, and the extending length of the screw rod 2 is limited by the adjusting nut 3. After the two screws 2 are sleeved into the connecting pipe 4, the length formed by the two screws 2 and the connecting pipe 4 is slightly smaller than the inner diameter of the reinforcement cage 6. The screw rod 2 is held by hand, the adjusting nut 3 is rotated, the screw rod 2 extends out, and the jacking 1 is contacted with the longitudinal ribs 6.2.
The end of the adjusting nut 3 is provided with a limit groove 3.1, and two ends of the connecting pipe 4 are propped in the limit groove 3.1 of the adjusting nut 3. The end of the adjusting nut 3 can be a plane as shown in fig. 1 or a limit groove 3.1 as shown in fig. 2. The limiting groove 3.1 is arranged to position the center of the connecting pipe 4.
The side wall of the adjusting nut 3 is provided with a handle 3.2 or the side wall of the adjusting nut 3 is a hexagonal prism surface. The hexagonal prism surface is convenient to rotate by a wrench, and the handle is convenient to directly rotate.
The two groups of connecting pipes 4 are fixedly connected into a whole through bolts 5. The two groups of connecting pipes 4 can be arranged at 90 degrees, so that four jacking supports the reinforcement cage circumferentially together, and stability is improved. The bolts 5 can be replaced by pins, so that the two groups of connecting pipes 4 can be adjusted to any angle, and can be folded after being disassembled.
The jacking 1 is an arc-shaped rod matched with the inner wall of the reinforcement cage 6.
The jacking 1 is an HRB400 steel bar, the length is 200mm, and the diameter is 25mm.
The connecting pipe 4 is a common welded steel pipe, and the specification is phi 48.3 multiplied by 3.6mm.
The specification of the bolt 5 is M10mm.
The inner ring of the longitudinal rib 6.2 is welded with a reinforcing ring, the reinforcing ring is a supporting reinforcing steel bar in the steel reinforcement cage design, and 1 group is arranged at each interval of 2 m.
The exposed length of the screw 2 should not exceed 300mm, and the depth of the screw 2 into the connecting pipe 4 should not be less than 150mm.
Working principle and process: a sufficient number of support means are made in the field before the reinforcement cage 6 begins to be worked. After the installation of the main reinforcement (longitudinal reinforcement 6.2) of the reinforcement cage and the spot welding of the main reinforcement (longitudinal reinforcement 6.2) of the reinforcement cage and the reinforcing rings are completed, a pile foundation reinforcement cage column diameter supporting device is installed between the two reinforcing rings to form an integral support. Before the finished steel reinforcement cage leaves the factory, the pile foundation steel reinforcement cage column diameter supporting device is completely removed and is used for the next construction cycle.
