Description

Technical Field

[0001] The utility model relates to the technical field of concrete component transportation, in particular to a transportation rack for precast concrete components. Background Art

[0002] A prefabricated building refers to a building in which some or all components are prefabricated in a factory and then transported to a construction site, where the components are assembled by reliable connection methods. Prefabricated components generally include precast stairs, wall panels, beam columns and other structures. Prefabricated components need to be pre-produced in a factory and then transported to a construction site for installation.

[0003] In the prior art, the patent number is: CN211996569U discloses a transportation rack for precast concrete components, including a cross beam. A firm rod is fixedly connected to the outer surface of one side of the cross beam near the middle position. An anti-collision rod is arranged at the upper end of the firm rod. A vertical rod is fixedly connected to the outer surface of the front end of the cross beam. A support rod is threadedly connected to the outer surface of one side of the vertical rod near the middle position. A connecting rod is fixedly connected between two adjacent groups of vertical rods. A ladder is fixedly welded to the outer surface of the other side of the cross beam near the middle position. The utility model can fix the transportation materials on the transportation rack, effectively protect the transportation materials, reduce the risk of transportation damage, avoid the cracking and breakage caused by the collision between materials, and is also convenient for users to move. It can be easily disassembled when not in use and is convenient for storage. This device is simple, easy to operate, and can more effectively solve the transportation damage during the transportation process.

[0004] Although the above transportation rack for precast concrete components can achieve the effect of transporting precast concrete components through the cooperation of components such as the cross beam and the firm rod, there are still the following deficiencies in actual application: when fixing and clamping concrete components, it is relatively troublesome to fix, and it is easy to collide with the cross beam and the fixed shaft during transportation, resulting in damage. Summary of the Utility Model

[0005] The purpose of the utility model is to propose a transportation rack for precast concrete components aiming at the problems existing in the background art.
