In order to solve the problems of the technologies described above, embodiment of the present utility model provides a kind of truss, comprise: upper chord, the lower chord be arrangeding in parallel with upper chord and many respectively with upper chord and the perpendicular montant of lower chord, between upper chord and lower chord, install the oblique abdomen member that diameter dimension is less than upper chord or lower chord diameter dimension.
Wherein, tiltedly abdomen member is steel strand or high tensile reinforcement.
Wherein, steel strand or high tensile reinforcement are along the relative upper chord of same tension direction or lower chord is unidirectional is in tilted layout.
Wherein, the relative upper chord of steel strand or high tensile reinforcement or lower chord inclined in two-way arranged crosswise.
Wherein, montant and the junction of upper chord and lower chord are respectively equipped with to be connected the engaging lug of oblique abdomen member.
Wherein, tiltedly the two ends of abdomen member are respectively equipped with pawl tool.
Wherein, upper chord and lower chord are round steel pipe.
Wherein, many montants are equidistantly arranged each other.
The invention also discloses a kind of rack with above-mentioned truss.
Truss provided by the utility model and rack are installed the oblique abdomen member of diameter dimension much smaller than described upper chord or described lower chord diameter dimension between upper chord and lower chord, can present as the state that there is no oblique abdomen member, form hidden brace trussed construction; Novel structure, can give full play to the mechanical property of steel strand or high tensile reinforcement, is widely used.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the utility model truss embodiment mono-.
Fig. 2 is the structural representation of the utility model truss embodiment bis-.
Fig. 3 is the structural representation of the utility model embodiment rack.
The specific embodiment
Below with reference to accompanying drawing, preferred embodiment of the present utility model is described.
Referring to Fig. 1, be the embodiment mono-of the utility model truss.
Truss in the present embodiment, comprise: upper chord 1, the lower chord 2 be arrangeding in parallel with upper chord 1 and many respectively with upper chord 1 and the perpendicular montant 3 of lower chord 2, between upper chord 1 and lower chord 2, install the oblique abdomen member 4 of diameter dimension much smaller than upper chord 1 or lower chord 2 diameter dimensions.
It is parallel that upper chord 1 and lower chord 2 are set to, and is normal formed steel construction.Upper chord 1 and lower chord 2 in the present embodiment are made as two round steel pipes.Many montants 3 are fastened between upper chord 1 and lower chord 2, and it adopts the round steel pipe with upper chord 1 and lower chord 2 same diameter, in the present embodiment, between many montants 3, equidistantly arrange each other.
In the present embodiment, tiltedly abdomen member 4 is along the relative upper chord 1 of same tension direction or lower chord 2 is unidirectional is in tilted layout, and the oblique abdomen member 4 of truss left-half as shown in the figure tilts for dextrad, and the oblique abdomen member 4 of truss right half part is as shown in the figure left-hand inclination.Wherein: tiltedly abdomen member 4 is used steel strand or the high tensile reinforcement of diameter dimension much smaller than upper chord 1 or lower chord 2 diameter dimensions, and its effect is as follows:
Because the general steel of the strength ratio of steel strand or high tensile reinforcement are high a lot of and be solid construction, because its diameter dimension is much smaller than the diameter dimension of upper chord 1 or lower chord 2, therefore as a whole, truss in the present embodiment, just as there is no oblique abdomen member 4, forms " hidden brace " trussed construction.
Steel strand or high tensile reinforcement that tiltedly abdomen member 4 is used can assemble by following mode, montant 3 and the junction of upper chord 1 and lower chord 2 are respectively equipped with to be connected the engaging lug 5 of oblique abdomen member 4, engaging lug 5 in the form of a ring, two ends at oblique abdomen member 4 are respectively equipped with pawl tool (not shown), the effect of pawl tool is to make oblique abdomen member 4 can be assembled to fast the junction of montant 3 and upper chord 1 and lower chord 2, during assembling, engaging lug 5 places that pawl tool need to be socketed in to diverse location place just can realize the assembling between steel strand or high tensile reinforcement and upper chord 1 or lower chord 2.
It should be noted that, when assembling steel strand or high tensile reinforcement, need to keep the suitable stretch-draw prestressing force of steel strand or high tensile reinforcement, to control pull bar, do not have significantly sagging.
Referring to Fig. 2, be the embodiment bis-of the utility model truss.
Truss in the present embodiment, comprise: upper chord 1, the lower chord 2 be arrangeding in parallel with upper chord 1 and many respectively with upper chord 1 and the perpendicular montant 3 of lower chord 2, between upper chord 1 and lower chord 2, install the oblique abdomen member 4 of diameter dimension much smaller than upper chord 1 or lower chord 2 diameter dimensions.
It is parallel that upper chord 1 and lower chord 2 are set to, and is normal formed steel construction.Upper chord 1 and lower chord 2 in the present embodiment are made as two round steel pipes.Many montants 3 are fastened between upper chord 1 and lower chord 2, and it adopts the round steel pipe with upper chord 1 and lower chord 2 same diameter, in the present embodiment, between many montants 3, equidistantly arrange each other.
In the present embodiment, tiltedly abdomen member 4 is used steel strand or the high tensile reinforcement of diameter dimension much smaller than upper chord 1 or lower chord 2 diameter dimensions, it is along upper chord 1 or lower chord 2 inclined in two-way arranged crosswise, as a whole, truss in the present embodiment is due to steel strand or high tensile reinforcement inclined in two-way arranged crosswise, not only can present as the state that there is no oblique abdomen member 4, form " hidden brace " trussed construction, and make formalness more attractive in appearance.
The invention also discloses a kind of rack, referring to Fig. 3, is the structural representation of the utility model rack, and the rack in the present embodiment is to be intersected and form through forward by above-mentioned truss, and its specific embodiment is identical with the embodiment of above-mentioned truss, repeats no more.
Implement truss of the present utility model and rack, between upper chord and lower chord, install the oblique abdomen member of diameter dimension much smaller than described upper chord or described lower chord diameter dimension, can present as the state that there is no oblique abdomen member, form hidden brace trussed construction; Novel structure, can give full play to the mechanical property of steel strand or high tensile reinforcement, is widely used.
Above disclosed is only the utility model preferred embodiment, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
