Abstract

The utility model discloses a beam-column rigid connection joint for a tubular concrete column, which comprises tubular steel tubes and inner partition boards welded in the tubular steel tubes; and two sides of the inner partition boards are connected with the tubular steel tubes respectively through fillet welds. After the finite element analysis and the simulation experiment, the welding between the tubular steel tubes and the inner partition boards is changed into double fillet weld from primary penetration weld under the premise of meeting the stress requirement, so that the welding speed is greatly increased, the tube wall is prevented from damage caused by concentration of welding lines, meanwhile, the influence of residual stress can be reduced to the utmost extent.

Description

A kind of pipe concrete column beam column rigid joint

Technical field

The utility model belongs to technical field of structural engineering, is specifically related to a kind of pipe concrete column beam column rigid joint.

Background technology

Use the steel core concrete column history of existing eight more than ten years in civil construction project, steel core concrete column has characteristics such as intensity height, mechanical property are superior, easy construction, is widely used in high level, strides greatly, in heavy duty and the earthquake proof construction.The validity of the node that steel core concrete column is connected with members such as beam, plates is the integrally-built rigidity of influence, stable and supporting capacity directly, also has influence on site operation difficulty and construction speed.At present, common pipe concrete column bean column node internal partition and the welding between round steel pipe are generally penetration weld, and the weld seam grade is one-level or secondary.Member speed of welding in welding process is slow, and weld seam is more concentrated, and residual stress is big, is easy to generate moderate finite deformation.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides that a kind of speed of welding is fast, welding deformation and the little pipe concrete column beam column rigid joint of residual stress.

The technical scheme that its technical problem that solves the utility model adopts is:

Pipe concrete column beam column rigid joint comprises round steel pipe and is welded on the interior internal partition of round steel pipe that it is characterized in that: the internal partition both sides are connected with round steel pipe by fillet weld respectively.

Described internal partition is provided with air-vent.

The beneficial effects of the utility model are: by carrying out finite element analysis and simulated experiment, satisfying under the prerequisite of force request, change the welding between round steel pipe and internal partition into twin fillet wolt by the one-level penetration weld, improved speed of welding greatly, avoided the concentrated damage of weld seam, can at utmost reduce the influence of residual stress simultaneously tube wall.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model front section view;

Fig. 2 is the utility model vertical view.

The specific embodiment

With reference to Fig. 1, Fig. 2, the utility model discloses a kind of pipe concrete column beam column rigid joint, comprise round steel pipe 1 and be welded on internal partition 2 in the round steel pipe 1.

As shown in the figure, in the present embodiment,, be welded with I-steel bracket 3 on round steel pipe 1 wall, be fixed with peg 4 on the steel corbel 3 in order to be connected with members such as beam, plates; For the lateral stiffness that increases the cross section and restriction distorting stress, be welded with the internal partition 2 suitable respectively in the concordant position of two legs up and down with I-steel in the round steel pipe 1 with i iron leg thickness, internal partition 2 both sides are passed through fillet weld 21 respectively and are connected with round steel pipe 1.Adopt fillet weld 21 not only to improve speed of welding, avoided the concentrated damage of weld seam, can at utmost reduce the influence of residual stress simultaneously tube wall.

Further, in order to make the concrete compaction that is poured onto in the round steel pipe 1, internal partition 2 is provided with air-vent 5.

Above-mentionedly just preferred embodiments more of the present utility model are illustrated and describe; but embodiment of the present utility model is not restricted to the described embodiments; as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.

Claims

1. a pipe concrete column beam column rigid joint comprises round steel pipe and is welded on the interior internal partition of round steel pipe, and it is characterized in that: the internal partition both sides are connected with round steel pipe by fillet weld respectively.

2. a kind of pipe concrete column beam column rigid joint according to claim 1, it is characterized in that: described internal partition is provided with air-vent.
