Description

TECHNICAL FIELD

[0001] The utility model belongs to underground subway station green intelligent construction technical field, specifically relates to a subway underground station room fabricated structure. BACKGROUND

[0002] The traditional method of subway underground station room (equipment room or management room) adopts masonry structure, that is, concrete blocks are used as wall body, cast-in-situ structural column and ring beam are set according to certain structure requirements.

[0003] The internal room of underground station adopts masonry structure, which is usually constructed after the completion of platform plate and station middle plate, and the concrete blocks are laid, the cement mortar is jointed and the surface is coated, and cast-in-situ reinforced concrete structural column is set at the wall corner and the middle position of wall according to the relevant technical requirements such as "masonry structure design specification", and cast-in-situ reinforced concrete ring beam is set at the top of wall.

[0004] The vertical steel bars of structural column are anchored in the platform plate or structure middle plate by punching and planting, and the masonry wall connected with the structural column is generally made into a zigzag shape so that the structural column and the wall body can be reliably connected. When the masonry wall is high, the cast-in-situ ring beam is additionally set at the middle position of wall height, and the steel bars of ring beam and the steel bars of structural column are reliably connected.

[0005] The reinforced concrete cast-in-situ beam is additionally set at the opening of door, window and the like, and the masonry wall, structural column and ring beam are connected to form a masonry structure room.

[0006] The defects of the existing subway underground station room are as follows:

[0007] (1) The vertical steel bars of structural column are anchored by punching in the structure plate, which causes irreversible damage to the structure plate, and even the punching may cut off the load-bearing bars of the structure plate.

[0008] (2) When the masonry wall is connected with the station frame column, in order to ensure the reliability of the connection, the steel bars are planted in the horizontal frame column, which causes damage to the frame column.

[0009] (3) The construction process is complex, including cement mortar mixing, masonry transportation, masonry, structural column steel bar planting, structural column and ring beam concrete pouring and the like. When the ring beam is set at the middle position of wall height, the wall above the ring beam cannot be continued to be built until the strength of the ring beam concrete reaches the requirement, and the construction efficiency is low.

[0010] (4) The degree of on-site civilized construction is low, and the working environment is poor. There are many materials such as cement, sand, blocks, steel bars and water in the small space of station, and the on-site construction organization is messy. The dust generated by cement, blocks and punching is large and difficult to discharge in time, which causes harm to human body.

[0011] (5) When the station construction period is tight, in order to meet the construction period requirement, the site is often synchronous for masonry, mechanical and electrical installation, decoration, each professional influences each other, the construction risk is high, and the construction organization and coordination difficulty is big.
