Abstract
The utility model provides a kind of retractor device shaped steel, is related to bridge extension joint shaped steel field, including main body, groove, the main body is divided into flash and side long, and flash and side long are in " 7 " font, the top surface of the side side long is inclined-plane B, and the groove is arranged on inclined-plane B lower sections；The utility model solves the shortcoming that vehicle causes greatly very much the concrete below shaped steel and shaped steel to be easily damaged the pressure at right angle of shaped steel.
Description
Technical field
The utility model belongs to building field, more particularly to a kind of bridge extension joint shaped steel.
Background technology
At present, domestic highway and Urban Bridge are fast-developing, have used substantial amounts of retractor device, retractor device to stretch
The reliability of device directly affects traffic safety, and the reliability of retractor device depends on the performance quality of shaped steel used.It is real at present
It is multiplex combined in railway bridge retractor device, it is made up of elastomeric material and metal material connector.Use is combined with beam-ends
Shaped steel, centre uses neoprene or EPT rubber packing.The top surface on the side long of conventional shaped steel and bottom surface are level
Face, effect when automobile passes through to whole shaped steel and new steel pipe bottom concrete is exerted oneself greatly, because the traffic density on road surface is high,
Shaped steel and concrete are easy to damage greatly due to the impulsive force being subject to.
Utility model content
The purpose of this utility model is to cause very much shaped steel and shaped steel greatly to the pressure at right angle of shaped steel to solve vehicle
The shortcoming that the concrete of lower section is easily damaged, so as to provide a kind of retractor device shaped steel.
The utility model is achieved through the following technical solutions above-mentioned purpose：
A kind of retractor device shaped steel, including main body, groove, the main body are divided into flash and side long, and flash and side long are in
" 7 " font, the top surface of the side side long is inclined-plane B, and the groove is arranged on inclined-plane B lower sections.
Further, the bottom surface of the side opposite side long is inclined-plane A.
Preferably, the groove is for outside is narrow, internal symmetric form groove wide.
Further, the length of the shaped steel is 60-61cm, and the Width x Height of the shaped steel is 50-51cm, the flash
Width be 28-29cm.
Further, the outwardly and inwardly connection of the groove includes the first circular arc for being sequentially connected, second line segment and the
Three-arc, first circular arc and three-arc are interior concave arc.
Further, the second line segment length is 18-19cm, and the radius of first circular arc and three-arc is
4.5cm。
Preferably, the shaped steel is Q345b shaped steel.
After such scheme, the beneficial effects of the utility model are：
The retractor device shaped steel that the utility model makes, shaped steel is changed into " 7 " font from original " 1 " font, and shaped steel is long
The top work surface on side is widened so that vertical bearing capacity increases, and ramp structure is increased in the top surface side on side long, has shared vehicle
To the vertical stress of shaped steel, when vehicle passes through, the applied stress of shaped steel and shaped steel bottom concrete diminishes, and protects whole
Retractor device and concrete；Meanwhile, when concrete is poured into a mould, the inclined-plane on the downside of shaped steel side long has automatic ventilating function.In addition,
Because groove up-down structure is symmetrical, and the outwardly and inwardly junction of groove is the combination of circular arc and straight line, the radius of circular arc and master
The specific proportions of body phase pair so that frictional force can be reduced when waterproof adhesive tape slides laterally, install, are very convenient to.
