Description

Technical Field

[0002] With the continuous development of building industrialization technology, prefabricated building construction technology has become increasingly mature and widely used in the field of rail transit engineering. The use of prefabricated construction technology for subway construction and the realization of on-site assembly prefabrication can comprehensively improve the quality of the project, speed up the construction speed, reduce the impact on urban ground traffic, and meet the requirements of high efficiency and environmental protection of urban underground projects. However, in the construction process of internal structures such as subway station air ducts, prefabricated technology is rarely used and is currently in the development stage. A set of prefabricated track top air ducts consists of two hanging walls and a duct board. All components are prefabricated in the factory and transported to the site. At present, during the storage and transportation of the prefabricated track top air duct hanging wall, due to the large volume and mass of a single component, it is easy to overturn and become unstable, resulting in the collision and cracking of the prefabricated track top air duct hanging wall, which cannot meet the on-site acceptance standards. Summary of the invention

[0003] The utility model aims to solve the deficiencies of the prior art and provides a storage and transportation device for a prefabricated rail-top air duct hanging wall in a subway station.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0005] A storage and transportation device for a prefabricated rail-top duct hanging wall of a subway station comprises transverse steel beams, longitudinal steel beams, oblique steel beams, vertical steel columns and steel plates. Four of the fourteen vertical steel columns are corner columns and are distributed in a rectangular shape. Six transverse steel beams and ten longitudinal steel beams cooperate with the vertical steel columns to form an upper and lower rectangular frame. The six transverse steel beams are respectively arranged on both sides, the middle of the bottom and both sides of the top of the rectangular frame. The ten longitudinal steel beams are divided into upper and lower layers and are correspondingly connected to the transverse steel beams. Four oblique steel beams form two groups of scissor braces and are fixed on the rectangular frame. The steel plates are arranged on the upper and lower transverse steel beams of the rectangular frame. Two "L"-shaped notches are cut on each steel plate, and a round tube is placed in each notch.

[0006] "L"-shaped notches are symmetrically cut on both sides of the steel plates, a rubber ring or a winding tape is sleeved on the round tube, and the round tube is inserted into the notches of the two corresponding steel plates.

[0007] The two groups of scissor braces composed of the oblique steel beams are placed under the second and fourth longitudinal steel beams of the upper layer and connected to the second and fourth longitudinal steel beams of the lower layer.

[0008] The transverse steel beams, longitudinal steel beams, oblique steel beams and vertical steel columns are all made of channel steel.

[0009] A triangular steel plate is welded at the connection between the vertical steel column, the transverse steel beam and the longitudinal steel beam.

[0010] The second and fourth vertical steel columns on the transverse outer side of the rectangular frame are welded with hanging rings on their tops.

[0011] A layer of soft rubber or soft plastic skin is adhered to the contact surfaces of the transverse steel beam and the longitudinal steel beam with the prefabricated track top air duct hanging wall.

[0012] The beneficial effects of the utility model are as follows: the utility model has a simple structure and is practical. The device can be used to efficiently and safely store and transport prefabricated track-top air duct hanging walls, thereby solving the problem that the single components of the prefabricated track-top air duct hanging walls are large in volume and mass, and the use of conventional platforms may cause damage to the stored and transported components.
