Description

Reinforcing steel bar installation auxiliary support and method Technical Field The invention relates to the technical field of building construction, in particular to an auxiliary support and a method for installing reinforcing steel bars. Background In the construction of large industrial and civil buildings, in particular circular or annular cylinder structures such as silos, granaries, storage bins and the like, binding and mounting of a reinforcement cage are a very critical procedure. With the increasing optimization of engineering design, the scale and the structural complexity of the silo are continuously increased, so that the space of a construction site, particularly a steel bar working surface is often very limited. In the traditional steel bar construction method, steel bars processed and formed in the background are usually lifted to the ground near a working surface through a tower crane or an automobile, and then are carried, positioned and bound one by constructors. However, the above conventional method has the following obvious drawbacks in specific construction scenarios such as silo: The construction efficiency is low, the labor intensity is high, the steel bars need to be transferred for many times, the transportation from the ground to the installation position completely depends on manual work, and the operation of workers is inconvenient in a silo with narrow space, the physical consumption is high, and the installation speed is slow; The installation precision is difficult to ensure, because the length and the weight of the steel bars (especially the screw thread steel) are large, the problems of position deviation, uneven spacing and the like easily occur in the manual transportation and the positioning process, the construction personnel need to repeatedly adjust the positions of the steel bars, the time is consumed, the key parameters such as the spacing of the steel bars, the thickness of a protective layer and the like are difficult to ensure to meet the design requirements, and the engineering quality is influenced; The adaptability is poor, and aiming at silos with different diameters or reinforcing steel bars with different lengths, a special auxiliary tool capable of being flexibly adjusted to adapt to the field size and the reinforcing steel bar specification is lacked, and the traditional method is a 'one-work-one-method' method, so that the recycling rate is low. Therefore, a special auxiliary device and method capable of improving the installation efficiency and accuracy of the reinforcing steel bars, reducing the labor intensity and adapting to complex construction conditions are needed. Disclosure of Invention Aiming at the defects of the prior art, the invention aims to provide an auxiliary support and a method for installing reinforcing steel bars, which can effectively improve the construction speed, flexibly adjust the length of the reinforcing steel bars and save the installation time. The technical scheme adopted for solving the technical problems is as follows: The auxiliary support for installing the reinforcing steel bars comprises a plurality of main supports, a telescopic adjusting mechanism and a reinforcing steel bar positioning clamping groove, wherein the telescopic adjusting mechanism is arranged between adjacent main supports and used for changing the distance between the adjacent main supports and adjusting the overall length of the auxiliary support, the telescopic adjusting mechanism is arranged on the main support and used for adjusting the supporting height of the main support, and the reinforcing steel bar positioning clamping groove is arranged at the top of the main support at intervals and used for supporting and restraining the transverse displacement of the reinforcing steel bars. Compared with the prior art, the invention has the beneficial effects that: The height and the length of the auxiliary support are adjustable, so that the auxiliary support can be quickly adapted to the requirements of different engineering structures, different construction stages and reinforcing steel bars with different sizes, the turnover use of the auxiliary support can be realized, the universality is high, the steel bar positioning clamping groove at the top plays a role in rolling prevention, the possibility is provided for accurate fine adjustment of deformed steel bars, the distance between the reinforcing steel bars, the lap joint length and the thickness of a protective layer are effectively ensured, and the quality of a reinforcing steel bar engineering is fundamentally improved.
