The first side wall 121 is fixed with upright bar 10.Upper cant beam 12 has by the first side wall 121, second sidewall 122 and the institute of connection wall 120
Two holding tanks 123 positioned at 120 both sides of connection wall crossed, the effect of holding tank 123 are to accommodate to have the work(such as heat-insulated, insulation
The material of energy, makes these materials not expose outside truss.Gone back respectively at the both ends of the first side wall 121 and second sidewall 122
Equipped with two card slots 124, the effect of card slot 124 is the exterior tarpaulin installation fixation for paulin room.Have in the first side wall 121 and stretch to
Two the first fins 125 of second sidewall 122, two first fins 125 are located at the both sides of connection wall 120, second sidewall 122 respectively
Inside accordingly it is equipped with two second fins 126.The cross section concrete structure of upper cant beam 12 is not limited with said structure, as long as be in
The section bar of existing I-shaped is among the design concept of this programme.The structure of lower inclined beam 11 is identical with upper cant beam 12, no
Introduce again.It is preferred that upright bar 10 is also H-shaped material as upper cant beam 12, therefore can be in upright bar and upper cant beam 12, lower inclined beam
Packing material is set between 11.
In foldable assembly 1, pivot joint is fixed at the bottom both ends of the first side wall 121 in upper cant beam 12 positioned at lower end respectively
Seat, and the top both ends of the second sidewall in lower inclined beam 11 positioned at upper end are also respectively fixed with pin joint seat, interior side lever 13, outboard beam
14 both ends are articulated in pin joint seat.
Review Fig. 1, the lower link 16 that foldable assembly 1 further includes knighthead 15 and some length differ, knighthead
15 lower end is fixed with upright bar 10, and upper end and the lower inclined beam 11 of knighthead 15 are fixed.By between lower inclined beam 11 and upright bar 10
Set knighthead 15 that the outboard end of upright bar 10, knighthead 15 and lower inclined beam 11 can be made to form firm triangle knot
Structure, so as to improve the structural strength of foldable assembly 1 or even whole truss.Lower link 16 is located within the above-mentioned triangle referred to,
The both ends of lower link 16 in the present embodiment are connected to upright bar 10 and knighthead 15, well imagine, lower link 16 can also
It is connected between lower inclined beam 11 and upright bar 10 or knighthead 15.Knighthead 15 and necessity that lower link 16 is not in gable
Component, can remove in some cases.
Upper cant beam 12, lower inclined beam 11 can be single overall rod piece or the knot being formed by connecting by multiple points of beams
Structure.Latter approach is used in the present embodiment.By increasing part or reducing upper cant beam 12, the number for dividing beam that lower inclined beam 11 includes
Amount, can also change size, the specification of truss to a certain extent.
It is second embodiment of the utility model shown in Fig. 4, foldable assembly 1, which further includes, in the present embodiment is connected to tiltedly
Multiple folding connecting rods 17 between beam 12 and lower inclined beam 11 and between interior side lever 13, outboard beam 14.The work of folding connecting rod 17
With being to improve stability of the foldable assembly 1 in deformation process.Preferably, 17 liang of two places of folding connecting rod intersect and are pivotally connected.
Understand using each two folding connecting rod 17 as a unit, it is cross that two folding connecting rods 17, which intersect, intermediate position phase
Mutually pivot joint, the upper end of two folding connecting rods 17 are connected to cant beam 12, and the lower end of two folding connecting rods 17 is connected to lower inclined beam 11.With reference to
Fig. 5, upper cant beam 12 have pin joint seat 18, and upper pin joint seat 18 has two groove positions 180 being inserted into for folding connecting rod 17, oblique
Beam 11 is equipped with lower pin joint seat 19, and lower pin joint seat 19 also has two groove positions 190, cross one another two folding connecting rods 17 it is upper
In two groove positions 180 of end insertion top and pin joint seat 18 is articulated in, two groove positions 190 of lower section are inserted into the lower end of two folding connecting rods 17
In and be articulated in lower pin joint seat 19.In above-mentioned first embodiment be arranged on upper cant beam 12,11 both ends of lower inclined beam pin joint seat knot
Structure can be identical with the upper pin joint seat 18 in the present embodiment, lower pin joint seat 19, the difference is that pin joint seat is solid in first embodiment
Cant beam 12 is scheduled on, on lower inclined beam 11, and in the present embodiment, to ensure that foldable assembly 1 can be folded, is unfolded, upper pin joint seat

Folding connecting rod 17 intersects two-by-two in above second embodiment, therefore the folding between upper cant beam 12, lower inclined beam 11
Connecting rod 17 is in structure, in another embodiment, multiple folding connecting rods 17 can also be set to single layer structure, i.e., upper pin joint seat
18th, only a groove position 180,190 need to be set in lower pin joint seat 19.
After being arranged in order using the foldable truss of multiple the utility model and being attached using rod piece, you can as paulin
The bearing frame in room.
Compared with prior art, the upper cant beam 12 in the utility model foldable truss, lower inclined beam 11, interior side lever 13 and
Outboard beam 14 forms the structure of foldable and deformable, two foldable assemblies 1 two on cant beam 12 one end it is frames rotatably mounted relative to one another so that two
Foldable assembly 1 can be connected and is integral.After the completion of erection truss, two upright bars 10 being fixed under two lower inclined beams 11 can
It is relatively close or remote, make foldable and deformable malformation above-mentioned in two foldable assemblies 1, so as to change whole truss
Horizontal span and height, truss is can be used in different field conditions, improve adaptability.Further, since upper cant beam
12nd, lower inclined beam 11 is H-shaped material, therefore can be easy to embedded various sound insulations, heat-insulated, thermal insulation material between section bar and section bar,
Material is hidden in inside truss at the same time, the performance in paulin room is improved while good appearance is kept.
Above disclosed is only the preferred embodiments of the utility model, its effect is to facilitate those skilled in the art
Understand and implement according to this, the interest field of the utility model cannot be limited with this certainly, thus it is special according to the present utility model application
The equivalent variations that sharp scope is made, still fall within the scope that the utility model is covered.
