Problems solved by technology
At the same time, there are still the following problems: 1) The side wall must consider the joint force of the enclosure structure, but the construction quality of the enclosure structure is not easy to guarantee, and it is difficult to meet the requirements of the century-old project; 2) The construction quality of the ground connection wall in the side wall composite wall structure It is not easy to guarantee, and it is easy to leak water after connecting the inner wall with steel bars; 3) The uplift piles on the bottom plate are not conducive to ensuring the waterproof quality of the station. The number of connection joints increases, which increases the hidden danger of water leakage; 4) At present, the thickness of the middle plate of the column-free station with a platform width of 9m has reached 650mm. It is not advisable to adopt the method of infinitely thickening the section
At the same time, the length of the opening at the escalator of the mid-slab building is greater than 9m, and the mid-slabs on both sides of the opening form an independent cantilever structure of about 6.5m. The structural layout is slightly unreasonable and the safety risk is high
5) The densely ribbed beam structure can achieve a larger span, but the construction is too cumbersome, and it is not suitable for application in the middle slab

Embodiment
[0036] Such as Figure 10 As shown, this embodiment takes a double-deck column-free station with a platform width of 11 m as an example, and the structural system parameters of the new double-deck pillar-less station are as follows:
[0037] Roof: An arch structure with an inner radius of 20 m and an outer radius of 30 m is adopted, the thickness of the vault roof is 700 mm, and the inner arch and the side wall adopt a circular arc transition with a radius of 2 m.
[0038] Middle plate: slab thickness 400 mm, slanting bracing 300 mm, slanting bracing angle about 9°, two ends of the middle plate are added with haunches, the space between the brace (rail top air channel plate) and the middle plate is also used as the rail top air channel, with an area of about 2 m2, a longitudinal beam (500 mm×1100 mm) is set at the intersection of the diagonal brace and the middle plate, and the opening between the two longitudinal beams can be used for the stair escalator, and the two ends o...

The invention relates to a double-layer column-free metro station structure system. An external main body of the station structure comprises a station top plate, side walls on the two sides and a station base plate, the station top plate and the station base plate adopt an arch structure, the station base plate and the side walls adopt circular arc transition, the inner wall is called as a top plate and side wall transition circular arc, the station base plate and the side walls adopt circular arc transition, and the inner wall is called as a base plate and side wall transition circular arc; amiddle plate is arranged between the side walls on the two sides, the two sides of the lower end of the middle plate are provided with obliquely supported rail top duct plates, and the other ends ofthe rail top duct plates abut against the side walls of the two sides. A cavity formed among the middle plate, each side wall and each rail top duct plate is a rail top duct. Accordingly, an uplift pile is not arranged, a retaining structure combined stress is not considered, full-wrap waterproof treatment is facilitated, the durability is easy to guarantee, and the system can be suitable for multiple geological conditions; top plate and bottom plate large span is achieved; the space effect and the decoration effect are good.
Description
technical field [0001] The invention relates to the field of subway station structure design, in particular to a structure system of a double-layer and column-free subway station. Background technique [0002] The current double-deck column-free station structure is a box-type frame structure, the roof is a folded plate, a variable cross-section plate, a ribbed beam and other structures, the middle plate is a thick plate structure, and the side walls are a composite wall or a laminated wall structure. It is mostly used in pillarless stations with platform width less than 10m. At the same time, there are still the following problems: 1) The side wall must consider the joint force of the enclosure structure, but the construction quality of the enclosure structure is not easy to guarantee, and it is difficult to meet the requirements of the century-old project; 2) The construction quality of the ground connection wall in the side wall composite wall structure It is not easy to...
