Abstract
A portable detachable girder comprises multiple girder rod elements and multiple interconnecting pieces. The girder rod element is not provided with a ribbed slab and screw nails are welded at the external circle of the girder rod element. Connecting holes are arranged at two ends of the interconnecting piece. The interconnecting piece is coated on the screw nails on the girder rod element and is screwed on the screw nail to realize connection through a nut. A girder structure is formed among multiple girder rod elements through this connection of the interconnecting piece. The technique scheme is improved in that joints are mounted at two ends of the girder rod element. Because the girder rod element is not provided with the ribbed slab and screw nails are welded at the external circle of the girder rod element, thus the girder rod element can be made conveniently, the structure is simple and the cost is lower. When joints are mounted at two ends of the girder rod element, the axial extending connection of the girder rod element can be realized and a multifunctional girder system can be formed. The portable detachable girder can be used to build agricultural sunshine sheds, buildings and scaffold system for decoration industry and be used for exhibition frame system in the advertising exhibition industry.
Description
Technical field
The utility model relates to a kind of truss, especially portable dismantled and assembled truss.
Background technology
The truss of Xiao Shouing mainly comprises truss member and connector in the market, be fixed by welding in together between truss member and the connector, make this integrally-built truss heaviness because truss is a metal material, connector can not separate with truss member, is inconvenient to transport and install.In order to solve the problem that integrally-built truss exists, dismantled and assembled truss has appearred, the patent No. is that the utility model patent of ZL 200320123120.8 discloses a kind of portable dismantled and assembled truss, comprise truss member and connector, have floor on the truss member, the floor that is connected on each truss member by connector between a plurality of truss members forms trussed construction.Because the connector of this truss and truss member can dismounting, conveniently transportation and installations.But this truss need be provided with floor on truss member, and truss member is made complexity, cost is higher.
Summary of the invention
Make complicated, cost problem of higher for the truss member that solves existing portable dismantled and assembled truss, the utility model proposes a kind of portable dismantled and assembled truss that improves structure.
For this reason, the technical solution of the utility model is: a kind of portable dismantled and assembled truss, comprise a plurality of truss members and a plurality of connector, and it is characterized in that: do not have floor on the truss member, but on the cylindrical of truss member, being welded with screw, the two ends of connector are provided with connecting hole; Connector is enclosed within on the screw on the truss member by connecting hole, is spun on by nut and realizes on the screw connecting, this trussed construction that is connected to form by connector between a plurality of truss members.
For the improvement of above-mentioned technical scheme, be to be provided with joint at the two ends of truss member.
Beneficial effect:
The portable dismantled and assembled truss of the utility model, convenient transportation and installation.Owing on truss member, there is not a floor, only on the cylindrical of rod member, be welded with screw, thereby make the easy to make of truss member, make truss simple in structure, cost is lower.
When the two ends at truss member are provided with joint, can realize the connection that extends axially of truss, form multi-functional trussing.
Described portable dismantled and assembled truss can be used for building agriculture sunlight booth, builds building, adnornment industry connection system for guide rail and is used for advertisement exhibition industry Display Rack system.
Description of drawings
Fig. 1 is a STRUCTURE DECOMPOSITION schematic diagram of the present utility model.
The specific embodiment
In conjunction with Fig. 1 the utility model is described.Portable dismantled and assembled truss comprises a plurality of truss members 2 and a plurality of connector 1, does not have floor on the truss member 2, but be welded with screw 3 on the cylindrical of truss member, and the two ends of connector 1 are provided with connecting hole 4; Connector 1 is enclosed within on the screw 3 by connecting hole 4, is spun on the screw 3 by nut 5 and realizes connecting, this trussed construction that is connected to form by connector between a plurality of truss members 2.Connector 1 is a butterfly, all is extended with two links at two ends, connects the end and has done the bending of 90-135 degree, and connecting hole 4 is arranged on 3 bending sides.
As shown in Figure 1, be provided with joint at the two ends of truss member 2, when truss did not need to extend axially connection, joint can be cancelled.
As shown in Figure 1, the joint design of the end of truss member 2 is: described joint is made up of nut 7, band cap bearing pin 8, retainer plate 9, stud 6, band cap bearing pin 8 passes nut 7, retainer plate 9, stretch out from nut 7, retainer plate 9 lower ends, band cap bearing pin 8 upper ends are supported on the interior step of nut and locate, band cap bearing pin 8 fixes with retainer plate 9 and is connected, thereby band cap bearing pin 8 axially is connected with nut 7, can rotate mutually between band cap bearing pin 8 and the nut 7; The following end-journal of band cap bearing pin 8 is provided with radial hole, the corresponding radial hole that is provided with on the wall of truss member 2, and the following end-journal of band cap bearing pin 8 is inserted in the endoporus of truss member 2, and band cap bearing pin 8 is connected with truss member 2 by Assembly of pin 9; Stud 6 is intermediate connectors supporting with nut 7, and stud 6 all stretches out the external screw thread axle journal from the middle to both ends.Need to realize extending axially when connecting, stud 6 one ends cooperate with the nut of truss member, and stud 6 one ends cooperate with the nut of another truss member, thereby realize extending axially connection.
Claims (3)
1, a kind of portable dismantled and assembled truss comprises a plurality of truss members and a plurality of connector, it is characterized in that: do not have floor on the truss member, but be welded with screw on the cylindrical of truss member, the two ends of connector are provided with connecting hole; Connector is enclosed within on the screw on the truss member by connecting hole, is spun on by nut and realizes on the screw connecting, this trussed construction that is connected to form by connector between a plurality of truss members.
2, a kind of portable dismantled and assembled truss according to claim 1, it is characterized in that: the two ends of described truss member are provided with joint.
3, a kind of portable dismantled and assembled truss according to claim 2, it is characterized in that: the structure of described joint is: be made up of nut, band cap bearing pin, retainer plate, stud, band cap bearing pin passes nut, retainer plate, stretch out from nut, retainer plate lower end, band cap bearing pin upper end is supported on the interior step of nut and locatees, band cap bearing pin is fixedlyed connected with retainer plate, thereby makes band cap bearing pin and nut shaft to being connected, and is with between cap bearing pin and the nut and can rotates mutually; The following end-journal of band cap bearing pin is provided with radial hole, the corresponding radial hole that is provided with on the wall of truss member, and the following end-journal of band cap bearing pin is inserted in the endoporus of truss member, and band cap bearing pin is connected with truss member by Assembly of pin; Stud is the intermediate connector supporting with nut, and stud all stretches out the external screw thread axle journal from the middle to both ends.
