Abstract
The utility model discloses a kind of antiskid cylindrical steel pipe concrete column and steel beam connecting joint, it comprises cylindrical steel pipe concrete column, steel I-beam, high-strength bolt; Outside regular polygon sleeve inner is circular hole, outside is the cylindrical hollow structure of regular polygon and outside regular polygon sleeve inner is provided with screw thread; Outside regular polygon sleeve set, on described cylindrical steel pipe concrete column, is provided with screw thread outside cylindrical steel pipe concrete column, and is fixedly connected with by high-strength bolt; Vertical junction plate quantity is four, is welded on four faces all around of described outside regular polygon sleeve respectively; Vertical junction plate is fixedly connected with by high strength friction-type bolt with belly with the upper and lower alar part of steel I-beam respectively, frictional force when especially screw thread can increase connection in the utility model, increase safety when node connects, structure is simple, construction welding job amount is little and easy and simple to handle, the overall steadiness of node is good, this device can reach Against Sliding Stability requirement, solves node when rod member connects and connects the problem of slippage.
Description
Technical field
The utility model relates to a kind of node connection device, and particularly skid resistance cylindrical steel pipe concrete column and steel beam connecting joint, be specifically applied to building engineering field.
Background technology
Along with expanding economy, connected node is more and more extensive, simultaneously also increasing to the influence power of building trade in the application of building trade.Also many research is had at the current utilizing status to connected node, a kind of cylindric through ribbed steel core concrete column and steel beam connecting joint is disclosed in Chinese Patent Application No. 201420294518, although its design have employed polygon outer sleeve, meet the steel core concrete column of different cross section form and the connection of girder steel by enclosing section form in change regular polygon sleeve.But still there is weak point, first, there is no need the node taking full through ribbed completely, waste material; Secondly, sleeve and outside sleeve are all smooth, can not ensure the stability of whole connected node.
Summary of the invention
The utility model patent provides a kind of antiskid cylindrical steel pipe concrete column and steel beam connecting joint, and this device can reach the firm requirement of antiskid, solves the appearance that rod member connects time dot crawl problem.
The utility model is a kind of skid resistance cylindrical steel tubes concrete column and steel beam connecting joint, comprises cylindrical steel pipe concrete column, steel I-beam, high-strength bolt, it is characterized in that, described coupling assembling comprises outside regular polygon sleeve and vertical junction plate; Outside regular polygon sleeve is connected by the two-way bolt of high strength, and vertical junction plate quantity is some, is welded on four faces all around of described outside regular polygon sleeve respectively; Vertical junction plate is fixedly connected with by friction-type bolt with belly with the upper and lower alar part of described steel I-beam respectively; Steel core concrete column is cylindrical, and its outside is provided with screw thread, be circular outside inside outside regular polygon sleeve be orthohexagonal hollow structure, also be threaded inside it, stem member is connected with tie point, node produces larger frictional force due to the effect of screw thread and rod member, thus reaches AsA-GSH cycle, makes the connection of rod member and node closely reliable.
As improvement, at the arranged outside screw thread of cylindrical steel pipe concrete column.
As improvement, screw thread is set inside outside regular polygon sleeve.
As improvement, high-strength bolt is adopted to be connected at outside regular polygon sleeve and steel core concrete column.
The invention has the beneficial effects as follows: it is simple that this design has structure, easy for installation, save material, high construction efficiency rate is improved; A kind of effect of antiskid can be played when structural element node is connected, ensure the stability and safety of connected node.

Detailed description of the invention
In figure, a kind of antiskid cylindrical steel pipe concrete column and steel beam connecting joint, by steel core concrete column 1, I-steel 2, high-strength bolt 4, vertical junction plate 5, friction-type bolt 6, screw thread 7 forms.Described steel core concrete column 1 interior shape is cylindrical, outer shape is that threaded cylinder matches with 7, outside arranges screw thread 7 at a certain distance, outside regular polygon sleeve pipe 3 is connected by high-strength bolt 4 reliably with steel core concrete column 1, I-steel 2 is connected with outside regular polygon sleeve 3 by vertical junction plate 5 simultaneously, and its connection is mainly connected by friction-type bolt 6.Mainly load onto screw thread in the inner side of the outside of concrete filled steel tube 1 and outside regular polygon sleeve 3, prevent the connection landing of node, even if there is a dot crawl a little, because there is screw thread 7 in the outside of whole steel core concrete column 1, so there is no fear of instantaneous landing occurs, so the safety of structure can not be affected because quick landing occurs the connection instability of node when carrying out rod member and being connected with node.
As improvement, screw thread 7 is added in the outside of steel core concrete column 1.
As improvement, also add screw thread 7 in the inner side of outside regular polygon sleeve 3.
As improvement, when outside regular polygon sleeve 3 is connected with steel core concrete column 1 with high-strength bolt 4.
