Specific embodiment
Below, the utility model is specifically described by exemplary implementation method.It should be appreciated, however, that not having
In the case of being further discussed below, element, structure and features in an implementation method can also be advantageously incorporated into other implementations
In mode.
, it is necessary to explanation, the length direction of the steel roof truss shown in Fig. 1 is as laterally in description of the present utility model；
Term " interior ", " outward ", " on ", D score, the orientation of the instruction such as "front", "rear" or position relationship be based on the position shown in accompanying drawing 1
Relation, is for only for ease of description the utility model and simplifies description, must rather than the device or element for indicating or imply meaning
Must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.This
Outward, term " first ", " second ", " the 3rd " are only used for describing purpose, and it is not intended that indicating or implying relative importance.
As shown in Figure 1 and Figure 2, a kind of steel roof truss, including transversely (length direction of the steel roof truss shown in Fig. 1 is as horizontal
To) the first steel roof truss unit 1 for setting, and with the first steel roof truss unit 1 along the second steel roof truss unit for being arranged side by side of longitudinal direction
5, (bottom is with the bottom of the steel roof truss structure shown in Fig. 1 for the two ends bottom of the first steel roof truss unit 1 and the second steel roof truss unit 5
Portion) the first pillar 2 is fixedly installed, the first pillar 2 is transversely arranged side by side with longitudinal direction；First steel roof truss unit 1 and the second steel
Multiple the 3rd steel roof truss units 6 being reciprocally coplanar are provided between roof truss unit 5, it is fixed between adjacent 3rd steel roof truss unit 6
Truss 3 is provided with, top of the two ends of truss 3 respectively with the first steel roof truss unit 1 and the second steel roof truss unit 5 is fixedly connected, edge
Laterally and it is fixedly installed the second pillar 4, the second pillar 4 and the first pillar 2 positioned at the bottom of the 3rd steel roof truss unit 6 at edge
Surround rectangular area.
It should be noted that traditional steel roof truss structure is：3rd steel roof truss unit 6 is integrated, and truss 3 one
End is fixedly installed on the 3rd steel roof truss unit, and the other end of truss 3 is fixed with the first steel roof truss unit 1 or the second steel roof truss unit 5
Connection.Traditional steel roof truss structure can cause that the load on roof and the weight of truss 3 mainly act on the 3rd steel roof truss unit 6
On, and then in the case of steel roof truss long span so that steel roof truss needs to increase because the stability of the 3rd steel roof truss unit 6 weakens
Plus more second pillars 4.
Understood referring to above-mentioned, the utility model is set by between the first steel roof truss unit 1 and the second steel roof truss unit 5
Multiple 3rd steel roof truss units 6, meanwhile, between adjacent 3rd steel roof truss unit 6 two ends are fixedly installed is individually fixed in first
The truss 3 at the top of 1 and second steel roof truss unit of steel roof truss unit 5, is set with this integration by tradition to the 3rd steel roof truss unit 6
Put and change into multiple and interval setting, and by tradition is to the multiple of truss 3 and interval setting changes into integrated setting, so that
So that truss bears to act on most active forces of the steel roof truss unit 6 of long span the 3rd as main force structure, enter
And improved with this without the stability by increasing the quantity of the second pillar 4 to improve steel roof truss when causing steel roof truss long span
The space availability ratio of steel roof truss, and reduce cost.
Further, since the span of the 3rd steel roof truss unit 6 is inversely proportional with its stability, i.e. the 3rd steel roof truss unit 6 across
Degree is smaller, and its stability is better, therefore, the utility model is total in steel roof truss also by increasing the quantity of the 3rd steel roof truss unit 6
In the case that span is constant, the span of each the 3rd steel roof truss unit 6 is reduced, so as to improve the 3rd steel roof truss unit 6
Stability, and then stability when improve steel roof truss long span.
Further as shown in Fig. 2 the one end of truss 3 corresponds to the top of the first steel roof truss unit 1 and the junction of the first pillar 2
It is fixedly installed, the other end of truss 3 corresponds to and is fixedly installed above the second steel roof truss unit 5 and the junction of the first pillar 2,
Utility model steel roof truss sets to the above-mentioned position of truss 3, and its effect is, in order to realize being transferred directly to the stress of truss 3
First pillar 2, the mechanical stability of steel roof truss is further increased with this.
Preferably, the number of the first steel roof truss unit 1 and the second steel roof truss unit 5 can be one, the 3rd steel roof truss list
Unit 6 can be two for being reciprocally coplanar.
In addition, as shown in Fig. 2 above-mentioned implementation method can also be improved to：First steel roof truss unit 1 and the second steel roof truss list
Unit 5 is and is mutually permanently connected and coplanar two, and the 3rd steel roof truss unit 6 is three for being reciprocally coplanar.It should be noted that
Above-mentioned implementation method is most preferred implementation method of the present utility model, and its reason is to be set to the 3rd steel roof truss unit 6
Three, the i.e. two ends positioned at middle are fixed on truss 3, and be located at two of two ends for two ends respectively with truss 3 and
First steel roof truss unit 1 is fixedly connected, or two ends are fixedly connected with the steel roof truss unit 5 of truss 3 and second respectively, with this side
Face causes that the 3rd steel roof truss unit 6 disclosure satisfy that the requirement of steel roof truss long span, while, it is ensured that steel roof truss possesses optimal receiving
Power stability；On the other hand, the application of the 3rd steel roof truss unit 6 and truss 3 is saved, and then saves cost.
For the connected mode between above-mentioned first steel roof truss unit 1, Ke Yiwei：As shown in Fig. 2 the first steel roof truss unit
It is bolted to connection between 1.Additionally, can also be bolted to connection between the second steel roof truss unit 5.
In addition, connected mode between the first steel roof truss unit 1 can also be welding, meanwhile, the second steel roof truss unit 5 it
Between connected mode also can also for welding.
In addition, the first steel roof truss unit 1 and the second steel roof truss unit 5 company of being bolted between the first pillar 2
Connect, be bolted to connection between the 3rd steel roof truss unit 6 and the second pillar 4, between the 3rd steel roof truss unit 6 and truss 3
It is bolted to connection, the utility model is by the first steel roof truss unit 1, the second steel roof truss unit 5 and the 3rd steel roof truss
Unit 6 is conducive to the dismounting and assembling of steel roof truss by the way of bolt fixation.
