The utility model discloses a steel roof truss ridge joint construction, two first steel sheets that are less than 180 are connected with the chord member, and roof truss ridge department has reduced welding seam length through the condition that this structure greatly reduced the upper chord member and connect the construction difficulty, has increased the construction space, has reduced stress concentration, has certain improvement to roof truss structure's arrangement intensity with stable.
Description
Technical Field
The utility model belongs to the technical field of housing construction, in particular to steel roof truss ridge connection structure.
Background
The roof truss structure is a plane or space structure system generally composed of straight bars, and is characterized in that the whole structure is mainly subjected to bending, and the components are mainly subjected to axial force. Under the action of load, the rod member mainly bears axial tension or pressure, so that the strength of the material can be fully utilized, the material can be saved compared with a solid web beam when the span is large, the self weight is reduced, and the rigidity is increased. The roof truss structure has a triangle shape, a trapezoid shape, an arch shape and the like according to different shapes, and has a wood roof truss, a steel roof truss, a reinforced concrete roof truss and the like according to different materials. At present, the light steel structure roof truss is a structural form which is mainly recommended in China, and has the characteristics of light weight, light and attractive structure, high construction speed, good economy and the like. The slope of its triangle-shaped roof truss generally is 1/2.5 to 1/2.0, the upper chord intersection forms the ridge in triangle-shaped roof truss, the upper chord generally adopts H shaped steel or two T shaped steel, but the upper chord generally adopts the steel sheet to connect at ridge department at present and forms the ridge node, traditional ridge node generally is field weld, the welding not only needs more welding workman, the welding is higher to welding workman's technical requirement, it is smaller to weld the space in ridge department simultaneously, cause the welding seam to be less full easily, also cause the crossing stress concentration of upper chord member easily, thereby influence the overall structure intensity of ridge and the life of structure.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a steel roof truss ridge joint construction convenient to construction.
The specific scheme is as follows:
the utility model provides a steel roof truss ridge connection structure, includes two chords, connects through the connecting piece between two chords, the connecting piece includes the steel pipe, and the equipartition has first steel sheet on the lateral wall of steel pipe.
The number of the first steel plates is 4.
The two non-adjacent first steel plates are in a group, wherein the angle between the two first steel plates of one group is less than 180 degrees.
And second steel plates are welded at two ends of the steel pipe through fillet welds respectively.
And the steel pipe and the first steel plate are welded through groove welding.
The utility model discloses a steel roof truss ridge joint construction is connected with the chord member through being less than two first steel sheets 180, and roof truss ridge department has reduced welding seam length through the condition that this structure greatly reduced the construction difficulty is connected to the upper chord member, has increased the construction space, has reduced stress concentration, has certain improvement to roof truss structure's arrangement intensity with stable.

FIG. 2 is a side view of a ridge connection;
fig. 3 is a roof ridge thumbnail.
In the figure: the steel pipe comprises a steel pipe 1, a first steel plate 2, a second steel plate 3 and a chord 4.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are only a part of the implementations of the present invention, and not all implementations, and all other embodiments obtained by those skilled in the art without any inventive work are included in the scope of the present invention.
As shown in fig. 1-3, a steel roof truss ridge connection structure comprises two chords 4, the two chords 4 are connected through a connecting piece, the connecting piece comprises a steel pipe 1, first steel plates 2 are uniformly distributed on the side wall of the steel pipe 1, and the number of the first steel plates 2 is 4. Two non-adjacent first steel plates 2 in a group, wherein the angle between the two first steel plates 2 of a group is less than 180 °. The steel pipe 1 and the first steel plate 2 are welded.
Two first steel sheets 2 with the included angle less than 180 degrees adjust the size of the included angle as required, are welded with the chord members 4 respectively, and are welded through groove welding between the steel pipe 1 and the first steel sheets 2. Roof truss ridge department has reduced the condition of chord member 4 connection construction difficulty through this structure greatly reduced, has reduced welding seam length, has increased the construction space, has reduced stress concentration, has certain improvement to roof truss structure's arrangement intensity and stability.
In order to avoid rainwater from entering the steel pipe 1, the two ends of the steel pipe 1 are respectively welded with the second steel plates 3, and the two ends of the steel pipe 1 are respectively welded with the second steel plates 3 through fillet welds.
The truss can be generally assembled on site before being manufactured and installed in a segmented mode according to the span size in the manufacturing process, the assembling mode is that ridge nodes are assembled, the assembling is completed and the hoisting and installation work is carried out after the assembly is qualified through inspection, the construction manufacturing process is as follows, the truss is manufactured in two sections, the ridge is separately manufactured, upper chords and lower chords are welded to the node plates, oblique web members and straight web members are welded to the node plates, after the chords on the two sides of the ridge and the web members are welded, the ridge is manufactured, first steel plates 2 are evenly welded to the peripheral sides of the steel pipes 1, the angles among a group of first steel plates 2 can be adjusted as required, and then the chords 4 are welded to the first steel plates 2 respectively. And after the whole roof truss is assembled, hoisting the whole roof truss to a corresponding position by adopting equipment, and carrying out installation work.
The utility model discloses a steel roof truss ridge joint construction is connected with chord member 4 through being less than two first steel sheet 2 of 180, and roof truss ridge department has reduced the condition of construction difficulty through this structure greatly reduced last chord member 4 connection, has reduced weld length, has increased the construction space, relative and directly weld between two chord member 4 before, stress ratio is concentrated, the utility model discloses a connecting piece that uses in the steel roof truss ridge joint construction, both sides get chord member 4 and weld with first steel sheet 2 of steel pipe 1 both sides respectively, with stress dispersion to steel pipe 1's both sides, have certain improvement to roof truss structure's arrangement intensity with stable.
The technical means disclosed by the scheme of the present invention is not limited to the technical means disclosed by the above embodiments, but also includes the technical scheme formed by the arbitrary combination of the above technical features. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications are also considered as the protection scope of the present invention.
