Abstract
The utility model discloses a steel landing stage is used on underground construction scene. The steel trestle consists of a steel column and a beam rigidly connected with the steel column; the steel column is a four-corner steel lattice column; the four-corner steel lattice column consists of two parts, namely a limb and a batten plate connected with the limb; the beam is an H-shaped steel beam; and stiffening ribs are arranged at the positions corresponding to the webs of the H-shaped steel beams in the four-corner steel lattice columns. The utility model discloses a steel is practiced thrift to the bending resistance ability of reinforcing component under the same axial resistance condition can be guaranteed to four corners steel lattice column.
Description
Technical Field
The utility model relates to a steel landing stage for underground construction scene.
Background
In some construction sites with relatively large ground height difference, the operation plane is deep underground, and a construction steel trestle is installed on site for facilitating transportation of construction vehicles.
Because the steel trestle is located the below ground, highly higher (about 19 m), and the steel trestle plane position and the building position coincidence in the follow-up construction in, if the steel trestle adopts the solid web column, can cut off former structure floor, influence the arrangement of reinforcement of structure floor.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects, the utility model provides a novel steel landing stage for underground construction field
In order to achieve the purpose, the steel trestle for the underground construction site of the utility model comprises a steel column and a beam rigidly connected with the steel column; the steel column is a quadrangular steel lattice column; the four-corner steel lattice column consists of two parts, namely a limb and a batten plate connected with the limb; the beam is an H-shaped steel beam;
and stiffening ribs are arranged at the positions corresponding to the webs of the H-shaped steel beams in the four-corner steel lattice columns.
Furthermore, the limb is an angle steel.
Furthermore, the stiffening ribs are composed of four steel plates, and two ends of each steel plate are welded to the middle points of two adjacent batten plates at the upper ends of the four-corner steel lattice columns to form a square shape.
Furthermore, an upper inner partition plate and a lower inner partition plate are arranged in the four-corner steel lattice column at positions corresponding to the flange of the H-shaped steel beam, and the inner partition plates and the steel column are welded with each other through cross stiffening ribs of the four-corner steel lattice column.
Furthermore, a sealing plate is arranged at the top of the four-corner steel lattice column.
The utility model discloses a steel is practiced thrift to the bending resistance ability of reinforcing component under the same axial resistance condition can be guaranteed to four corners steel lattice column. The lattice column with the structure can be conveniently constructed by a grouting pipe or other large-diameter pipes.
Drawings
Fig. 1 is a schematic top view of the present invention.
Fig. 2 is a side view of fig. 1.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 and fig. 2, the steel trestle of the utility model for underground construction site comprises a steel column and a beam rigidly connected with the steel column; the steel column is a quadrangular steel lattice column 1; the four-corner steel lattice column consists of two parts, namely a limb and a batten plate connected with the limb, wherein the limb is an angle steel; the beam is an H-shaped steel beam 4;
and stiffening ribs 5 are arranged at the positions corresponding to the webs of the H-shaped steel beams in the four-corner steel lattice columns. The stiffening ribs are composed of four steel plates, and two ends of each steel plate are welded to the middle points of two adjacent batten plates at the upper ends of the four-corner steel lattice columns to form a square shape. The inside stiffening rib of square shape can be through slip casting pipe or other big diameter pipe, the construction of being convenient for. Therefore, the structure safety is ensured, and the construction is not influenced.
An upper inner partition plate 2 and a lower inner partition plate 2 are arranged in the four-corner steel lattice column at positions corresponding to flanges of the H-shaped steel beam, and the inner partition plates and the cross stiffening ribs of the four-corner steel lattice column of the steel column are welded with each other.
The above description is for illustrative purposes only, and it is obvious that the present invention is not limited by the above embodiments, and the present invention is not limited by the above description, and the present invention is applicable to other situations without any improvement or any substantial improvement.
