Description

technical field

The present invention relates to the technical field of architectural engineering, more particularly to a pillar head servo system elevating device of a temporary tubular steel pillar.

State of the art

With the rapid increase in urban population, congestion is currently a growing problem, especially in inner cities. An effective solution to this problem is the construction of underground railroad junctions in urban centers. Because urban cores are often characterized by small lots, a large number of above-ground surrounding buildings in the area, and a complex composition of surface traffic, a covered, top-down excavation method is often employed. For large underground transportation hubs, especially for main structures with a large number of inclined columns as the main structure of the main supporting columns, reservation of inclined columns and excavation method are carried out from the bottom up to ensure the safety of the main structure during construction, because the inclined columns add an additional load to the slab, so that the forces on the temporary support system increase. This poses a problem that the temporary support system rises after installing the inclined columns and the structural forces are converted. In the prior art, there has not yet been known a lifting device of a servo system for a pillar head of a preliminary tubular steel pillar. In summary, we propose a lifting device of a servo system for the column head of a temporary tubular steel column.

A reinforcing bar 10 is firmly connected through the side walls of the steel blocks 9, and the height of the steel columns 7 is greater than the initial height of the lifting jacks 8. It is arranged as follows: In the initial state, the steel columns 7 are initially located below the supported object lying on top. When the force state needs to be changed, the hoisting winch 8 can be directly synchronously driven so that the hoisting winch 8 rises and at the same time the supported object is lifted. And while the steel columns 7 support the overhead supported object, the load of the overhead supported object is transmitted to the preliminary tubular steel column 11 via the steel columns 7 . After the winch 8 lifts up, the overhead, supported object gradually supported by the winch 8. At this time, the load of the overhead supported object is transmitted to the temporary steel pipe column 11 via the winch 8 . In the lifting operation of the present embodiment, the preliminary tubular steel column 11 is used to support the overhead load, thereby ensuring the overall structural stability of the invention.

A pillar cap 16 is connected to the bottom of the lower plate 1 by screws. The pillar cap 16 and the bottom plate 1 are provided with a plurality of screw holes 12 corresponding to the screws. On the side of the column cap 16 facing away from the lower plate 1, a preliminary tubular steel column 11 is connected. The lower plate 1 is provided with a plurality of screw holes 12, each two screw holes 12 are divided into a group, and sixteen groups of screw holes are evenly distributed on the circular periphery of the lower plate 1 with a diameter of 1000mm.

The lower plate 1 is designed in particular as a hollow steel plate. Disposed within the lower plate 1 are three equally spaced transverse inner rib plates 14 and two longitudinal inner rib plates 15 perpendicularly fixed to the transverse inner rib plates 14, the longitudinal inner rib plates 15 and the lower plate 1 having four oblique Inner rib plates 3 are firmly connected. Since the load of the overhead supported object carried in the present embodiment is not too large, the lower plate 1 is made of a hollow steel plate for cost reasons. The carrying capacity of the invention can be further increased by cooperation of the transverse inner rib plates 14, the longitudinal inner rib plates 15 and the oblique inner rib plate 3. The oblique inner fin plates 3 are at an angle of 45 degrees to the transverse inner fin plates 14 and the longitudinal inner fin plates 15, thereby forming a triangular stable structure. The lower plate 1 is connected to the pillar cap 16 and also to the preliminary steel tube pillar 11 . Deformation may occur during power transmission.

The steel columns 7 are firmly connected to the upper plate 2 by means of a flange plate 5, and on the flange plate 5 a plurality of reinforcing ribs 6 distributed in a ring are fixed. The reinforcing ribs 6 are fixed to the outer periphery of the steel pillars 7 . The reinforcement ribs 6 and the flange plate 5 serve to reinforce the connection and increase the resistance to deformation.

At the same time, in embodiment 1, the dimensions of the components are as follows: the thickness of the transverse inner fin plates 14, the longitudinal inner fin plates 15 and the oblique inner fin plates 3 is 25 mm, the intermediate round steel pipe 13 is a seamless steel pipe with a diameter of 800 mm and a thickness of 16 mm, the upper plate 2 and the lower plate 1 are steel plates with a thickness of 25 mm. The flange plate 5 is a steel plate with a thickness of 20 mm, the reinforcing rib 6 is a steel plate with a thickness of 10 mm. The steel column 7 has a mass of 250t, a diameter of 135mm and a height of 570mm. The diameter of the steel blocks 9 is 220 mm and the diameter of the reinforcing bar 10 is 20 mm.
