Abstract

The utility model discloses an inner separating board and an outer ring board combined type concrete filled square steel tube column and a girder cross-shaped node. Inner separating boards are arranged inside square steel tubes on an upper flange and a lower flange of a girder in a welding mode. The outer walls of the square steel tubes on the upper flange and the lower flange of the girder are respectively provided with the outer ring board in a welding mode. The lateral sides of a square steel tube on a web of the girder are respectively provided with a vertical connecting board. The upper and the lower flanges of the girder are connected with the outer ring boards in a welding mode. The web of the girder is connected with the vertical connecting boards through high-strength bolts. The inner separating board and outer ring board combined type is adopted by the node, and therefore force is more easy to convey. The inner separating boards are welded, and tension force and pressure on the upper and lower flanges of the girder are conveyed more effectively. The outer ring boards are welded, and character of simple connection between the node and the girder is inherited.

Description

Internal partition and outer ring plate convolution concrete-filled steel square tubular column and girder steel cross node

Technical field

The utility model relates to building engineering structure, especially relates to frame construction.

Background technology

Along with the development of building structure, steel-concrete combined structure becomes a kind of generally acknowledged new structural system, and itself and steel work, wooden construction, masonry structure and reinforced concrete structure are arranged side by side, to be expanded into the fifth-largest structure.Steel-concrete combined structure has been given full play to concrete and has been born pressure and the mechanical properties of materials of steel bearing tension, is conducive to reduce the heavy in section of crossing of concrete structure, and the improvement of satisfying fire prevention and anti-seismic performance.

Using more in the steel-concrete combined structure is encased structures, so-called encased structures be exactly pour into concrete in the steel pipe and tamping to add the strength and stiffness of big steel pipe.This structure has been given full play to the strong point of steel pipe and concrete bi-material, has that bearing capacity is high, plasticity and advantages such as good toughness, easy construction, is widely used in the structures such as individual layer and multi storied industrial factory building post, highrise building and bridge.This year particularly, along with the promotion and application of steel structure of housing, the frame structure that forms with steel core concrete column and girder steel ties up to and is applied gradually in the engineering practice and develops, and has obtained good economic benefit and social benefit.

In the frame construction that concrete-filled steel square tubular column and girder steel form, the cross connected node form of beam, post mainly contains that outer shroud is board-like, internal partition formula and dividing plate are through.Because board-like independent use of internal partition formula and outer shroud can not be transmitted the beam-ends pulling force well; The through concrete-filled steel square tubular column bottom flange correspondence position on girder steel that requires of dividing plate blocks, diaphragm is welded in the relevant position after, again weld former square steel pipe, node construction is complicated, weld seam is more concentrated.

The utility model content

The purpose of this utility model is to solve the technological deficiency that concrete-filled steel square tubular column and girder steel cross node exist in the prior art, and a kind of internal partition and outer ring plate convolution concrete-filled steel square tubular column and girder steel cross node are provided.

For achieving the above object, the technical solution that the utility model is taked is:

A kind of internal partition and outer ring plate convolution concrete-filled steel square tubular column and girder steel cross node, it comprises concrete-filled steel square tubular column and the firm beam of I-shaped, it is characterized in that, in the square steel pipe at place, the upper and lower edge of a wing of girder steel, be welded with respectively upper and lower internal partition, weldering is connected with a circle outer ring plate respectively on the square steel pipe outer wall at place, the upper and lower edge of a wing of girder steel, four sides at the square steel pipe of steel beam web plate position is welded with respectively vertical junction plate, the upper and lower edge of a wing of girder steel is welded respectively and is connected on the upper and lower outer ring plate, and steel beam web plate is connected on the vertical junction plate by high-strength bolt.

The utlity model has following useful technique effect:

The utility model joint structure is simple, processes easy for installationly, and power transmission is clearly reliable, has adapted to the suitability for industrialized production demand.The utility model node combines the form of internal partition and outer ring plate, is more conducive to power transmission; The welding internal partition effectively transmits pulling force and the pressure of bottom flange on the girder steel; The welding outer ring plate has been inherited self and simple characteristics of being connected of beam.

Description of drawings

With reference to the accompanying drawings, the utility model is described in further detail.

Fig. 1 is concrete-filled steel square tubular column and steel beam joint front view;

Fig. 2 is the top view of concrete-filled steel square tubular column and steel beam joint.

Among the figure: 1-square steel pipe, the upper internal partition of 2a-, internal partition under the 2b-, 3-steel I-beam, 4-high-strength bolt, 5-concrete, the vertical junction plate of 6-, the upper outer ring plate of 7a-, outer ring plate under the 7b-.

The specific embodiment

As shown in Figure 1 and Figure 2, internal partition of the present utility model and outer ring plate convolution concrete-filled steel square tubular column and girder steel cross node, be in the square steel pipe 1 that the top flange of steel I-beam 3 is located, to be welded with internal partition 2a, in the square steel pipe 1 that the bottom flange of girder steel 3 is located, be welded with lower internal partition 2b; Square steel pipe 1 outer wall weldering at place, girder steel 3 top flanges is connected with a circle outer ring plate 7a, and square steel pipe 1 outer wall at place, girder steel 3 bottom flanges is welded with outer ring plate 7b under the circle; Side at the square steel pipe 1 of girder steel 3 web position is welded with respectively vertical junction plate 6, and the weldering of girder steel 3 top flanges is connected on the outer ring plate 7a, and the weldering of girder steel 3 bottom flanges is connected on the outer ring plate 7b; Girder steel 3 webs are connected on the vertical junction plate 6 by high-strength bolt 4.Be concrete 5 in the square steel pipe 1.
