Abstract

The invention discloses a novel assembled type beam column joint connecting structure which comprises beams, a sleeve (9) arranged between the beams and a lower column (16) matched with the sleeve (9) and an upper column (15) in an inserted mode. Each beam is composed of two parallel steel angle beams (1) and the adjacent steel angle beams (1) are welded into a whole through steel angle beam connecting boards (2). The whole sleeve (9) is of a cuboid structure with openings formed in the two ends and an upper sleeve flange (4) and a lower sleeve flange (6) are welded to the edges of the opening ends of the sleeve respectively. The whole novel assembled type beam column joint connecting structure is low in mass, capable of saving energy, environmentally friendly, high in construction speed, high in industrialization degree, suitable for the development of the building industry of China and capable of effectively solving multiple problems that the building industrialization level of China is low, the house building labor productivity is low, and traditional house products are low in quality.

Description

A kind of novel fabricated connecting structure of beam column nodes

Technical field

What the present invention relates to is field of steel structure, and what be specifically related to is a kind of novel fabricated connecting structure of beam column nodes.

Background technology

In the full welding node of tradition beam column, bottom flange, Liangshan and web and the on-the-spot welding of post, although this type of attachment is for being rigidly connected, ductility of joint is poor, easily brittle fracture occurs in earthquake, and need on-the-spot welding, greatly have impact on speed of application and quality, be unsuitable in assembling type steel structure, simultaneously because bonding area is large, the residual stress that easy generation is larger, affects the stress performance of node.

In tradition high-strength bolt tie-beam Column border node, beam-ends shrouding and box column are fastenedly connected by high-strength bolt, time fastening, workman needs handle to reach in box column, this form of construction work makes troubles to the fastening work of bolt when constructing, bolt hole can weaken node short column simultaneously, affects its stress performance.

In tradition bolted and welded connection node, bottom flange and post Site Welding on beam column, web plate is by shear plate and post bolt, this connected mode needs on-the-spot welding, greatly have impact on speed of application and quality, and construction sequence is complicated, is not easy realization and is rigidly connected.

Summary of the invention

The present invention proposes a kind of novel fabricated connecting structure of beam column nodes, its objective is the defect being to overcome prior art, meet the every mechanical property of node, realize bean column node to be rigidly connected, and realize the assembling of structure, improve the assembled speed of component, fully adapt to requirement and the feature of assembling type steel structure system.

In order to solve problem existing in background technology, it comprises crossbeam, the lower prop 16 being arranged on the sleeve 9 between crossbeam and coordinating with sleeve 9 and upper prop 15 grafting respectively; Described crossbeam is made up of two parallel angle steel crossbeams 1, an entirety is welded into by angle steel cross-beam connecting plate 2 between two adjacent angle steel crossbeams 1, described sleeve 9 is overall is provided with the rectangular structure of opening for two ends, the edge of its openend is welded with sleeve upper flange 4 and sleeve lower flange 6 respectively, the upper weld of described lower prop 16 has the two pieces of lower prop end plates 10 coordinated with sleeve 9 grafting, the other end of this lower prop end plate 10 extends in upper prop 15 through sleeve 9, and is spun by bolt and be integrally fixed.

The bottom welding of described upper prop 15 has the upper prop flange 3 docked with sleeve upper flange 4, and the periphery of described upper prop flange 3 offers the screw of through setting.

Be welded with the lower prop flange 7 docked with sleeve lower flange 6 near the root of described lower prop end plate 10, the periphery of described lower prop flange 7 offers the screw of through setting.

Owing to have employed above technical scheme, the present invention has following beneficial effect: total quality is light, energy-conserving and environment-protective, speed of application is fast, industrialization degree is high, the problems such as effectively can solve that China's industrialization of construction industry level is low, house building labor productivity is low and conventional house product quality is low, adapt to the development of China's building trade.

Detailed description of the invention

The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention being clearly and completely described.

Embodiment 1

Referring to Fig. 1-3, it comprises chord member frame, and described chord member frame comprises crossbeam, the lower prop 16 being arranged on the sleeve 9 between crossbeam and coordinating with sleeve 9 and upper prop 15 grafting respectively; Described crossbeam is made up of two parallel angle steel crossbeams 1, an entirety is welded into by angle steel cross-beam connecting plate 2 between two adjacent angle steel crossbeams 1, described sleeve 9 is overall is provided with the rectangular structure of opening for two ends, the edge of its openend is welded with sleeve upper flange 4 and sleeve lower flange 6 respectively, the upper weld of described lower prop 16 has the two pieces of lower prop end plates 10 coordinated with sleeve 9 grafting, the other end of this lower prop end plate 10 extends in upper prop 15 through sleeve 9, and is spun by bolt and be integrally fixed.

Owing to have employed above technical scheme, the present embodiment has following beneficial effect: total quality is light, energy-conserving and environment-protective, speed of application is fast, industrialization degree is high, the problems such as effectively can solve that China's industrialization of construction industry level is low, house building labor productivity is low and conventional house product quality is low, adapt to the development of China's building trade.

Embodiment 2

Chord member frame is processed in advance in factory according to structure disclosed in embodiment 1, upper prop 6 and lower prop 8, only need carry out docking consolidation service when the later stage is transported to job site, on-the-spot without welding job requirements, and the layout of bolt is also easy in manual operation, substantially increase assembling speed and quality.

Last it is noted that above embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art should be appreciated that it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
