Description
Technical Field
The utility model relates to an engineering construction technical field, concretely relates to circulated use's triangular supports subassembly for consolidate cylindrical steel reinforcement cage, improve steel reinforcement cage's resistance to deformation ability.
Background
The cylindrical reinforcement cage 6 for engineering comprises a reinforcement cage main reinforcement 6a, a reinforcement ring 6b in the reinforcement cage and a reinforcement ring 6c outside the reinforcement cage. In the work progress such as bridge foundation and substructure, in order to guarantee that the steel reinforcement cage does not warp, does not distort in handling and installation, traditional way mainly has two kinds:
firstly, the overall rigidity is increased by welding a plurality of regular-triangular steel bar supports 7 at intervals along the longitudinal direction of the cage body in the steel bar cage, as shown in fig. 4, but the following problems exist:
(1) the waste of the reinforcing steel bar material is large. The triangular steel bar support adopts steel bars with the same diameter as the main steel bars of the steel bar cage, is only reinforcing steel bars in the steel bar hoisting process, and is not designed structural steel bars. If the supporting steel bars are not removed in the process of installing the steel bar cage, the loss amount of the steel bars is large.
(2) The security risk is large. Even if the supporting steel bars are removed in the process of installing the steel bar cage, in order to protect the performance of the steel bars, a cold cutting process is adopted, and due to the limit of the space between the main steel bars of the steel bar cage, the operation space is narrow, and the safety risk is high; and after each time of dismantling, each supporting steel bar is about 20cm in loss, the length is shortened, and the supporting steel bars cannot be recycled and become waste materials.
(3) The work efficiency is low. According to actual measurement on a construction site, the average time for dismantling a triangular steel bar support exceeds 30 minutes.
And secondly, the circular ring end of the M30 turn-buckle 8a into two parts, and the hook end of the turn-buckle is welded with the phi 28 supporting steel bar 8b in an overlapping manner to be used as a supporting rod 8, as shown in figure 5. The two semicircular rings as the two ends of the supporting rod are propped against the inner reinforcing ring of the reinforcement cage. Two bracing pieces are "ten" font shore in the steel reinforcement cage, but have following problem:
(1) the turnbuckle is connected with the supporting steel bar in a welding mode, and the performance of the supporting steel bar is reduced after being heated, so that the performance of the supporting rod is reduced; limited by the construction of the turn buckle, the lap joint length between the turn buckle and the supporting steel bar is limited, and the safety is low.
(2) The diameter of the ring end of the turn buckle is smaller, and the turn buckle cannot be in complete contact with the reinforcing steel bar of the reinforcing ring of the reinforcement cage after being cut off.
(3) The support points at the two ends of the support rod are not on the same axis and are easy to deform and destabilize due to the structure of the turn buckle.
(4) The two support rods are in a cross shape, the support steel bars and the reinforcing ring steel bars of the steel reinforcement cage cannot be located on the same cross section, the stress performance is poor, and the support body system is easy to destabilize. And because this support system is not in same cross-section, easily make the reinforcing bar warp after repetitious usage, in order to ensure to support firm, need to make again, take a lot of work and waste material.
(5) The diameter of the steel reinforcement cage is numerous, the adjustable length of the turn buckle is limited, the applicability is poor, the steel reinforcement cage with each diameter cannot be adapted to use, supporting rods with various lengths need to be equipped, and the material waste is large.
