Lattice column penetrating structure floor slab node structure for underground station construction

Technical Field

The utility model relates to a subway station, in particular to a structure floor node structure is worn to lattice column for subway station construction.

Background

With the acceleration of subway construction in China, the construction of underground stations faces the construction problem of increasingly large deep foundation pits. In the construction of a foundation pit, an inner support and a fender post or an inner support and an underground continuous wall are mostly adopted as a foundation pit supporting structure, when the depth of the foundation pit is deep or the width of the foundation pit is large, the axial force of the inner support is large, in order to ensure the stability and the safety of the inner support, a lattice column is usually arranged in the middle position in the length direction of the support, and the lattice column is used as a supporting point of the inner support.

During the station construction, vertical lattice column intersects with the horizontal structure floor is perpendicular, and the traditional construction methods of node that the lattice column wore the structure floor are for reserving the hole in floor relevant position, and after the lattice column was demolishd to the later stage, chiseled the floor reinforcing bar and carry out welded connection, and the concrete of building slab trompil position is poured again.

Traditional structure post wears node construction mode of structure floor, causes the floor reinforcing bar discontinuous, need the manual work to chisel out and weld after the floor reinforcing bar, and the construction process is complicated, and engineering time and capital cost are great.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a structure floor node structure is worn to lattice column for underground station construction is provided to effectively avoid in the underground station construction because the floor reinforcing bar discontinuous problem that lattice column caused, reduce the loaded down with trivial details process that the floor reinforcing bar was dug out in later stage

The utility model provides a technical scheme that its technical problem adopted as follows:

the utility model discloses a node construction that is used for structure floor is worn to lattice column of underground station construction, including its lattice column, characterized by: the lattice column is formed by welding equal-corner steel members and steel batten plates, the equal-corner steel members are positioned at four corners of the rectangular section and serve as limbs, and the steel batten plates are welded and connected with two adjacent equal-corner steel members; the crossing node position department of lattice column and station structure floor, pass the reinforcing bar hole on the steel batten board face with the perpendicular crossing structural slab reinforcing bar of steel batten board, the adjacent structural slab reinforcing bar of lattice column both sides is buckled and is walked around the lattice column.

The utility model has the advantages that the problem of discontinuous floor slab steel bars caused by lattice columns in the construction of underground stations is effectively avoided, and the complex procedure of chiseling the floor slab steel bars in the later period is reduced; the node is simple in structure, low in construction cost, high in construction operability and easy to popularize and use in underground station construction.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

Referring to fig. 1 to 3, the utility model discloses a node structure of a lattice column penetrating structure floor slab for underground station construction includes its lattice column A, lattice column A is formed by equilateral angle steel component 1 and steel lacing plate 2 welding, and equilateral angle steel component 1 is located the rectangle section four corners as the limb, and steel lacing plate 2 welded connection is adjacent two equilateral angle steel components 1. The 4 equal-edge angle steel members 1 serve as main axial force bearing members, and the 4 steel gusset plates 2 mainly resist lateral force. The crossing node position department of lattice column A and station structure floor 3, the steel bar hole 4 on the 2 faces of steel batten plate is passed with the perpendicular crossing structural slab reinforcing bar 5 of steel batten plate 2, and the adjacent structural slab reinforcing bar 5 in lattice column A both sides is buckled and is walked around lattice column A. The problem of 5 discontinuous floor reinforcing steel bars caused by lattice column A in the underground station construction is effectively avoided, and the complicated process of chiseling out the floor reinforcing steel bars in the later period is reduced

The concrete implementation steps of the node structure of the lattice column penetrating structure floor slab for underground station construction are as follows:

1. constructing a pile foundation of the lattice column A;

2. excavating a foundation pit of the station;

3. welding and manufacturing a lattice column A, arranging a steel bar hole 4 on a steel batten plate 2 of the lattice column A at the intersection position of a station structural floor slab 3 and the lattice column A, wherein the size of the steel bar hole 4 is determined according to the diameter of a steel bar 5 of a structural plate;

4. laying structural plate steel bars 5, wherein the structural plate steel bars 5 which are vertically intersected with the batten plates 2 penetrate through steel bar holes 4 on the plate surfaces of the batten plates 2, and the structural plate steel bars 5 adjacent to two sides of the latticed column A are bent to wind around the latticed column A;

5. a station structure floor 3 and side walls;
