Description

A kind of new steel truss

Technical field

The utility model belongs to civil engineering plant technical field, and in particular to a kind of new steel truss.

Background technology

Truss is a kind of structure being hinged each other at two ends by rod member.The general tool that truss is made up of straight-bar There are the plane or space structure of triangular element, truss member is primarily subjected to axial tension or pressure, so as to make full use of material The intensity of material, material is saved when span is larger than solid web girder, mitigates deadweight and increase rigidity.Sent out with the high speed of construction industry Exhibition, the application of steel construction is more and more extensive, the use of truss is increasingly standardized in steel construction, earliest truss is adopted Set with fixed structure, right truss use can not carry out dismounting consumptive material it is huge, in order to solve this technical problem, in the prior art Fixed truss is substituted using detachable truss, still, often due to loosening, which easily occurs, in connecting portion also make it that truss is specific With there is larger potential safety hazard.

Utility model content

For above-mentioned weak point of the prior art, the purpose of this utility model is intended to provide a kind of detachable and steady Qualitative stronger new steel truss.

In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：

Some montants are vertically installed between a kind of new steel truss, including cross bar, cross bar, cross bar and montant junction are oblique To brace is provided with, it is fixedly connected between cross bar, montant and brace by positioning lock piece.

Further preferably, the positioning lock piece includes reverse-locating part and angle adjustment part, and inverted orientation part includes anti- To adjustment lock piece, hole and inverted orientation connector are reverse-located, angle adjustment part includes angle adjustment lock piece, angle adjustment Locking hole and angle adjustment lock piece connection end, reverse-locate connector and are plugged in inside angle adjustment lock piece connection end, instead Connected to positioning link with angle adjustment locking hole by being connected limit shaft, the inverted orientation hole and angle adjustment locking hole Match, how plane angle adjustment lock piece connection end outer layer be.

Further preferably, the angle adjustment lock piece bottom is set and spring is set inside inner groovy, inner groovy, and angle is adjusted Anti- stops is set at whole lock piece bottom axis.

Further preferably, the connection limit shaft bottom sets locating part, and locating part matches with anti-stops.

Specifically, angle adjustment lock piece is pulled down first, when certain position is moved to, angle adjustment locking Part adjusts cross bar, montant and brace to angle the most suitable, then decontrols angle adjustment lock piece, angle adjustment locking Part will set spring so as to resilience due to inside so that three angle adjustment lock pieces reverse-locate connector with top and are in card And locking state, so as to realize that cross bar, montant and brace are fixed.

The utility model has advantages below relative to prior art：

The utility model can realize comprehensive rotation of multi-angle, while can be made at work relative to staff Power is opposition, according to the relation of physics principle active force and reaction force cause the utility model stability with Adaptability is extremely strong, is easy to be widely popularized popularization and uses.

Brief description of the drawings

In order to illustrate more clearly of the utility model embodiment, letter will be done to the required accompanying drawing used in embodiment below Single introduction, it should be apparent that, drawings in the following description are only some embodiments of the present utility model, general for this area For logical technical staff, on the premise of not paying creative work, other accompanying drawings can also be obtained according to these accompanying drawings.

Fig. 1 is the utility model structural representation；

Fig. 2 is the connector explosive view of the utility model.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than it is all real Apply example.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made, institute The every other embodiment obtained, belongs to the utility model protection domain.

Some montants 2 are vertically installed between a kind of new steel truss as shown in Figure 1 and 2, including cross bar 1, cross bar 1, it is horizontal Bar 1 with the junction of montant 2 is angularly disposed brace 3, fix company by positioning lock piece 4 between cross bar 1, montant 2 and brace 3 Connect.

Further preferably, the positioning lock piece 4 includes reverse-locating part 4a and angle adjustment part 4b, reverse-locates part 4a Adjusted including reversely adjustment lock piece 4a1, inverted orientation hole 4a2 with reverse-locating connector 4a3, angle adjustment part 4b including angle Whole lock piece 4b1, angle adjustment locking hole 4b3 and angle adjustment lock piece connection end 4b2, reverse-locate connector 4a3 grafting Inside angle adjustment lock piece connection end 4b2, connector 4a3 is reverse-located with angle adjustment locking hole 4b3 by being connected limit Position axle connection, the inverted orientation hole 4a2 matches with angle adjustment locking hole 4b3, outside angle adjustment lock piece connection end 4b2 How plane layer be.

Further preferably, the angle adjustment lock piece 4b1 bottoms, which are set, sets spring, angle inside inner groovy, inner groovy Anti- stops is set at degree adjustment lock piece 4b1 bottom axis.

Further preferably, the connection limit shaft bottom sets locating part, and locating part matches with anti-stops.

Specifically, angle adjustment lock piece 4b1 is pulled down first, when certain position is moved to, angle adjustment Lock piece 4b1 adjusts cross bar 1, montant 2 and brace 3 to angle the most suitable, then decontrols angle adjustment lock piece 4b1, Angle adjustment lock piece 4b1 will set spring so as to resilience due to inside so that three angle adjustment lock piece 4b1 and top are anti- Card and locking state are in positioning link 4a3, so as to realize that cross bar 1, montant 2 are fixed with brace 3.

The utility model is described in detail above.Help is only intended in the application to the explanation of operation principle to manage Solve core concept of the present utility model.It should be pointed out that for those skilled in the art, not departing from this reality On the premise of with new principle, the utility model can also be made improvements and modifications, these are improved and modification also falls into this reality With the protection model of new claim with interior.
