Description
Technical field
The present invention relates to the light steel structure stiff frame of a kind of metal rigid frame connector and connection thereof.
Background technology
Lightgage steel joist system house has characteristics such as wall thickness is little, light weight, anti-seismic performance is good, speed of application is fast, need not a template, pipe line arrangement is convenient, has obtained in recent years using widely in the building trade of China.In the tradition lightgage steel joist system house, body of wall load-bearing skeleton and flooring roof girder generally all adopt C type light gauge cold-formed steel shape, and thickness of section is generally 0.6-2.0 mm.Because the flakiness ratio on the C type cross section web and the edge of a wing is bigger, when being subjected to the vertical axis press loading effect, cripling takes place and reduces element bearing capacity in the web and the edge of a wing easily too early, if as the stress frame in the body of wall, generally is used for the low-rise building of 1-3 layer.If floor joist adopts real abdomen formula C type or other opening light gauge cold-formed steel shape cross section, then cross section partial pressing ability and stability bearing capacity are lower, and it is less to be suitable for span.
At present, lightgage steel joist system house also has directly does body of wall stress frame, floor and roofing spandrel girder with the pipe truss, and its way is:
Side's (square) shape steel tube directly is used as chord member, and the V-type connector by the stamping forming C of having tee section is connected with self-tapping screw.This way is simple to operate, and bearing capacity is big.But the expense material that causes during production V-type connector is too big, and it is more to connect used self-tapping screw.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of stamping connector and light steel structure stiff frame thereof, solve too big, the more technical problem of self-tapping screw of conventional metals V-arrangement spare expense material.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of stamping connector, it is the tabular whole connector that is stamped to form by steel plate, it is characterized in that: the upper edge interposition of described tabular whole connector is equipped with circular arc cutaway, the lower edge interposition of described tabular whole connector is equipped with down circular arc cutaway, the centre on the left and right both sides of steel plate is spill, and the edge of spill has perpendicular to the plate face and to the edge of a wing of steel plate back side bending flange.
The front of steel plate, be distributed with at least one streak from top to bottom, have the hole of tightening up a screw, have screw hole down in the both sides of streak bottom in the both sides on streak top to the protruding drum of the positive circular arc of steel plate.
The front of above-mentioned steel plate, be distributed with three streaks from top to bottom to the protruding drum of the positive circular arc of steel plate, wherein, middle streak is a vertical bar, about two streak symmetries, the upper end of left side streak is to the bending of the upper left corner of steel plate, the lower end is to the bending of the lower left corner of steel plate, the upper end of the right streak is to the bending of the upper right corner of steel plate, the lower end is to the bending of the lower right corner of steel plate, on the on the left side streak on the both sides of crooked position and the right streak both sides of crooked position have the hole of tightening up a screw, under the on the left side streak under the both sides of crooked position and the right streak both sides of crooked position have down screw hole.
The upper and lower side of above-mentioned left side streak and the right streak has circular arc to seamlessly transit in the knee.
Above-mentioned steel plate can be the cold rolling or hot rolled steel plate of thickness 0.6-6.0 mm.
Rectangular or the arc chord angle in four bights of above-mentioned steel plate.
A kind of light steel structure stiff frame of using described stamping connector connection, it is characterized in that: fixedly connected with light steel rigid frame upper chord through the hole of tightening up a screw in the top of above-mentioned tabular whole connector, the bottom warp of above-mentioned tabular whole connector screw hole is down fixedlyed connected with light steel rigid frame lower chord, and above-mentioned edge of a wing flange just in time is stuck between light steel rigid frame upper chord and the light steel rigid frame lower chord.
The cross section of the cross section of above-mentioned light steel rigid frame upper chord and light steel rigid frame lower chord is rectangle, C shape or the hat of clod wash or hot-roll forming.
Beneficial effect of the present invention is as follows:
The present invention is a kind of rigid frame connector of writing board shape, that section flat board at its rigid frame connector middle part carries out flange and circular arc, dull and stereotyped front is provided with some streaks, the screw hole that connects self-tapping screw is set, and is a kind of economical with materials, supporting capacity is big, outward appearance is beautiful, easy to operate, stressed rational rigid frame connector.This connector and rigid frame are used for lightgage steel joist system house, as body of wall load-bearing skeleton and flooring, roofing spandrel girder, will improve house component and whole supporting capacity greatly, make and use house of the present invention safety and reliability, the scope of application is wider, more economical with materials and economy.
Be connected for screw between the lower edge on connector of the present invention and the rigid frame.Rigid frame connector of the present invention is a writing board shape, and there are three roads or some streaks in the centre, can increase the resistance to compression supporting capacity of web member itself like this.The upper and lower of rigid frame connector is attached to the part on lower edge surface also for dull and stereotyped, have screw hole on the flat board, conveniently to be threaded and contraposition, the requirement of national Technical code for design of coldformed thin wall steel structures (GB50018-2002) is all satisfied to the distance of plate edge in pitch of holes and hole, and the quantity in hole is decided according to the supporting capacity of rigid frame connector.
Three roads or some streaks in the middle of the rigid frame connector are directly reached the screw hole junction, and streak outwards protrudes, one side does not hinder being close to of rigid frame connector upper and lower and chord member surface like this, the more important thing is the resistance to compression bearing capacity that has strengthened plate part.
By implementing punching press rigid frame connector of the present invention, increased the bearing capacity of junction, improved the integrated carrying ability of truss.
In addition, the end of punching press rigid frame connector of the present invention has increased little circular arc, makes integral body seem more beautiful and level and smooth.
The present invention is the whole shape punching press rigid frame connector that a kind of usefulness is cold rolling or hot rolled steel sheet, aluminium alloys or glass epoxy are one time punching molded, and it is big to have supporting capacity, and appearance looks elegant is stressed reasonable, applied widely, produces and characteristics easy to operate and that save material.Three roads or some streaks of outside protrusion are set on the punching press rigid frame connector, so not only do not hinder being close to of punching press rigid frame connector and last lower chord surface, and strengthened the present invention's resistance to compression supporting capacity itself.
Use punching press rigid frame connector of the present invention, by self-tapping screw or bolt punching press rigid frame connector is connected with last lower chord and can easily forms various rigid frames and lightweight steel construction thereof, made things convenient for the connection of self-tapping screw, the installation rate of light steel structure stiff frame and the bearing capacity of lightweight steel construction have been significantly improved, and then can improve house component and whole supporting capacity greatly, can be widely used in the stress frame, flooring, roofing spandrel girder of light steel building structure body of wall.
