Problems solved by technology

However, due to the limitations of on-site construction and construction deviations, the perfect butt welding can only be performed when the bending angles of the steel bars are exactly the same, and the site usually cannot be accurately aligned; It is impossible to correct the steel bar when pointing, and the steel bar is too rigid. Therefore, it is difficult to realize the lap welding of the steel cage to meet the requirements of the code.
Therefore, in order to save trouble on site, pre-bending is usually not performed, which obviously violates the requirements of the specification

Embodiment 1

[0029] Such as Figure 1 to Figure 5 As shown, the present embodiment is used for the construction method of steel cage overlap correction connection, and this construction method comprises the following steps:

[0030] Step 1: Roughly align the No. 1 lap joint 11 on the No. 1 steel bar 1 and the No. 2 lap 21 on the No. 2 steel bar 2, and keep the partial joints of the two steel cages The direction of the steel bar is straight;

[0031] Second step: open the crimping joint 32 of the manual hydraulic clamp 3, and clamp the No. 1 lap joint 11 on the No. 1 reinforcement cage reinforcement bar 1 and the No. 2 lap joint 21 on the No. 2 reinforcement cage reinforcement bar 2 two reinforcements, Close the crimping head 32, insert the pin 33, manually press the hydraulic handle 35, and squeeze the two separated No. Alignment of a joint bar between cage bar 1 and No. 2 cage bar 2;

[0032] Step 3: Then the No. 1 lap 11 and the No. 2 lap 21 steel bars are welded and fixed with weldin...

Embodiment 2

[0040] The structure of the construction method used in this embodiment for the rectification and connection of the steel cage overlap is basically the same as the structure of the construction method for the construction method of the reinforcement cage lap correction connection in Embodiment 1, the difference is that the hanging mechanism 5 includes a fixed Plate 51, support plate 52, fixing bolt 53, support screw rod 54 and support bracket 55 (see Figure 6 and Figure 7 ). The top of the fixed plate 51 is provided with a support plate 52, the fixed plate 51 on the outside of the support plate 52 is provided with a fixed bolt 53, the support screw 54 is threadedly installed on the support plate 52, and one side of the support screw 54 runs through the support plate 52 for fixed installation. Bracket 55, the fixed plate 51 is fixedly installed on the top of the pile hole 6 by the fixing bolt 53, which is convenient for the fixing of the reinforcement cage unit section in th...

Abstract

The invention discloses a construction method for lap-joint correction connection of reinforcement cages. The construction method comprises the following steps: 1, roughly aligning reinforcement cage reinforcements on a first lap-joint part on a reinforcement cage reinforcement and a second lap-joint part on a reinforcement cage reinforcement, and keeping the directions of partial joint reinforcements of the two reinforcement cages to be straight; and 2, opening a pressing head of a manual hydraulic clamp to clamp the first lap joint part on the first reinforcement cage reinforcement and the second lap joint part on the second reinforcement cage reinforcement, closing the pressing head, inserting a plug pin, and manually pressing a hydraulic handle. A series of structures are arranged, and the manual hydraulic clamp is used for forcibly correcting the lap joint parts of the reinforcements, so that joints of the two reinforcements which cannot be in lap joint are temporarily fixed together, and the purpose of normal welding is achieved; and large hydraulic machinery is not needed on site, two operators can complete joint connection work, the construction difficulty is reduced, the construction efficiency is high, and the connection precision meets the standard requirement.

Description

technical field [0001] The invention relates to the technical field of steel cage lap joints, in particular to a construction method for correcting and connecting steel cage lap joints. Background technique [0002] For the construction of bored piles, first use drilling machines to form holes, and then hoist the steel cages into the holes in sections. Because the steel cages are long, they are usually processed in sections, and the sections are connected by welding, and then reach the design length of the steel cages. According to the requirements of the specification, when the two-section reinforcement cage is connected by lap welding, the centerlines of the two overlapping reinforcement bars must be coaxial. Therefore, when processing the reinforcement cage, it is necessary to pre-bend the reinforcement within the overlapping range in advance to ensure that the welding meets the specification. Require. However, due to the limitations of on-site construction and construct...
