Embodiment one
Reference picture 1, the light-wall pipe 1 that the embodiment of the present invention one is provided, including cylindrical body 11, cylindrical body 11 is by four flat boards
12 are enclosed and form, and three right angles of cylindrical body 11 are equipped with to be formed at chamfering 13, each chamfering 13 to be connected with adjacent two flat board 12
The connecting plate 14 connect, the cross section that such flat board 12 of three connecting plates 14 and four is enclosed is heptagon.Carried out in three right angles
Chamfered, for every piece of flat board 12, its width reduces, and in phase homonymy external force, width is smaller, and its anti-side impact capacity is got over
By force, thus the setting of chamfering 13 enhances the anti-side impact strength of four flat boards 12；Moreover, for cylindrical body 11, its cross section
The length of side is more, and its bonding strength is better, and vertical compressive resistance is also better, therefore the setting of chamfering 13 also enhances the vertical of light-wall pipe 1
Compressive resistance.
Reference picture 2, Fig. 3, light-wall pipe 1 are arranged at the inner corner trim 2 in room, and the floor at inner corner trim 2 presets hole 21, light-wall pipe
1 forms common gas exhaust passage through hole 21.Light-wall pipe 1 is when laying, wherein being close to inner corner trim 2 at a chamfering 13, at this chamfering 13
Connecting plate 14 and inner corner trim 2 two vertical walls between form triangular space 22, this triangular space 22 is easy to pour into slurry 3 to consolidate
Light-wall pipe 1 is determined, the problem of solving the external corner of former rectangle thin wall pipe and can not pour into slurry 3 to the inner corner trim 2 in room.Meanwhile, thin-walled
The another two chamfering 13 of pipe 1 is close to form angle between the connecting plate 14 at two metopes of inner corner trim 2, each chamfering 13 and metope respectively
A, and angle a is at an acute angle, you can facilitate slurry 3 to block vertical seam in angle a, more former rectangle thin wall pipe is parallel with the metope of inner corner trim 2
Seam, is enhanced sealedly convenient, firm and reliable.
In the present embodiment, the width of connecting plate 14 is less than the width of flat board 12, the width range of connecting plate 14 be less than
10cm.The width of general connecting plate 14 is optimal between 2cm~5cm, can so take into account cost, also can guarantee that its sealedly side
Just it is, firmly and reliable.
In the present embodiment, connecting plate 14 is preferably flat board, so, convenient production and processing.Certainly it can also be other knots
Structure, such as outer arcuate plate, arc plate or polygon.
In the present embodiment, offered in cylindrical body 11 and duty valve (not shown) be installed on air inlet 15, air inlet 15,
Duty valve is generally check-valves or fire resisting damper or non-return, fire prevention, is oriented to Multifunctional combined valve, and duty valve is mainly used in preventing from sharing
Waste gas pours in down a chimney or prevents the functions such as fire spread in exhaust duct.
In the present embodiment, cylindrical body 11 by the integral solidified forming of slurry, its can also be bound, be bonded by flat plate splicing and
Into.
In the present embodiment, metalwork (not shown) is embedded with cylindrical body 11.Metalwork was installed in light-wall pipe 1
Play a part of self-supporting or positioning in journey.
In the present embodiment, reinforcer or lightweight thing are provided with cylindrical body 11, reinforcer is reinforcing bar, steel wire, bar-mat reinforcement, fibre
Dimension, fibre bundle, fibrous mesh cloth, non-woven fabrics, web band, have in hole thin strip, strap, braid over braid, stalk extremely
Few one kind；Lightweight thing is at least one of wood chip, stalk, foam, polyphenyl alkene, and lightweight thing can suitably reduce weight, be easy to
Carry and install.
Embodiment two
Reference picture 4, Fig. 5, the present embodiment and the difference of embodiment one are：Four right angles of cylindrical body 11 are equal
Provided with chamfering 13, the cross section of light-wall pipe 1 is in octagon, and so, its anti-side impulsive force, resistance to vertical compressive resistance are also better, gas stream
The general character can be also more preferable.And other three chamferings 13 set be the same as Example one, therefore the light-wall pipe 1 in the present embodiment still solves wall
The problem of slurry is difficult to pour at inner corner trim 2, tube wall and metope parallel slit are difficult sealing.
Embodiment three
Reference picture 6, Fig. 7, the present embodiment and the difference of embodiment one are：Only one of which right angle in cylindrical body 11
Place is provided with chamfering 13, and the cross section of light-wall pipe 1 at inner corner trim 2, so, is connected in the connecting plate 14 at pentagon, and chamfering 13
Triangular space 22 is formed between plate 14 and two vertical walls of inner corner trim 2, this triangular space 22 is easy to pour into slurry 3 to fix thin-walled
Pipe 1, the problem of slurry curing fixes light-wall pipe 1 can not be poured into the inner corner trim 2 in room by solving the external corner of former rectangle thin wall pipe.
Example IV
Reference picture 8, Fig. 9, the present embodiment and the difference of embodiment one are：Only one of which right angle in cylindrical body 11
Place is provided between the connecting plate 14 at chamfering 13, be the same as Example three, chamfering 13 and two vertical walls of inner corner trim 2 and forms triangular space
22, this triangular space 22 is easy to pour into the solidification of slurry 3 to fix light-wall pipe 1, solves the external corner of former rectangle thin wall pipe 1 to room
Inner corner trim 2 the problem of can not pour into slurry 3.Meanwhile, in the present embodiment, the top and bottom of cylindrical body 11 and along its barrel to
Outer to be extended with toss 16, toss 16 is in closed form, it is of course also possible to be in non-closed shape.As can be seen from Figure, toss 16 is formed
Strengthening wing strengthens the intensity of cylindrical body 11, effectively improves the mechanical property of light-wall pipe 1, enhances its stability, prevents
Light-wall pipe 1 produces longitudinal jackknifing in carrying and installation.Certainly, also toss 16 only can be set in one end of cylindrical body 11, this
Place and install when sample is readily transported.
Reference picture 10, when many light-wall pipes 1 are stacked, the docking open area of adjacent two light-wall pipe 1 not only includes original wall
Thick contact area, includes the area of toss 16, so also solves the docking port of light-wall pipe 1 docking area in the prior art small not
The problem of easily sealing；Meanwhile, when the light-wall pipe 1 of two floor gaps is stacked, the two gap between floor 23 is sealed by slurry 3
When, the toss 16 protruded in outside can play supporting and retaining system effect to slurry 3, so be not required to set bed die again；Moreover, the vertical gap of closure
Slurry 3 withstands the support for producing interlayer after solidifying, the stacked pressure at right angle of multiple light-wall pipes 1 is reduced, so in installation process
In be also not required to carry out support unloading with reinforcing bar or angle bar.
In the present embodiment, the outerplanar of toss 16 is concordant with the end face of cylindrical body 11.Certainly, the outerplanar of toss 16
The end face of cylindrical body 11 can be less than, or, the outerplanar of toss 16 is higher than the end face of cylindrical body 11.
Preferably, the width of toss 16 is 1cm~2cm.Because the wall thickness of cylindrical body 11 is general between 1cm~2cm,
The width of toss 16 is set to 1cm~2cm, the need for cost and intensity can be taken into account simultaneously.
In the present embodiment, barrel of the toss 16 along cylindrical body 11 is in have to lack between non-closed shape, the two ends of toss 16
Mouthful, i.e., it is L-shaped setting.Certainly, toss 16 can also be enclosed outside light-wall pipe 1 for closed form.
In the present embodiment, the rectangular cross-section of toss 16, naturally it is also possible to be triangle, trapezoidal or irregular figure.
These are only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Any modifications, equivalent substitutions and improvements made within principle etc., should be included in the scope of the protection.
