100 can be also used for the construction of the tower building of chemical field application, here with no restriction.Wind is only hereafter used for purlin 100
It is illustrated for the construction of power tower.
As depicted in figs. 1 and 2, the purlin 100 according to an embodiment of the present invention for tower pouring construction, purlin 100 have
Have it is multiple enclose section 10, multiple sections 10 of enclosing circumferentially join end to end, and purlin 100 is formed as ring structure, in this way, carrying out to tower
Before pouring, purlin 100 can be set in the outside or inside of formwork for placing (not shown).
For ease of understanding the structure of purlin 100 and use principle, tower work progress will be briefly described below.
Tower includes at least tower barrel base and tower ontology in structure, and tower barrel base is equivalent to the ground of entire tower building
Base, tower ontology are located on tower barrel base.Tower ontology includes multiple tower segments sequentially connected from bottom to top, at least partly tower
Cylinder section concrete tower segments made of concrete casting.
In casting concrete tower segments, needs first to install inside and outside two layers of template, reserve annular between inside and outside two layers of template
Die cavity, to the die cavity casting concrete between inside and outside two layers of template when construction.The concrete poured can sufficiently discharge the heat of hydration
And internal stress, concrete tower segments are formed in maintenance concrete hardening after a certain period of time.
It is understood that since the concrete poured can discharge internal stress in hardening process there is expansion in concrete
And squeeze the process of inner and outer template.To resist this part stress, the inner and outer template that the prior art uses is relatively bulky.And it is each
Template is assemblied to form by multiple modules circumferentially arranged, there is provision of complex mechanical structure guarantee between adjacent block
Module not decylization.
And the purlin 100 of the embodiment of the present invention, it is applied to the construction of this concrete tower segments, exactly to pour in concrete
It is set on formwork for placing before building.Purlin 100 can housing in the outside of the exterior sheathing installed, purlin 100 can also be located at branch
If the inside of good inner template.
When outside of 100 housing of purlin in exterior sheathing, since purlin 100 is ring structure, it is equivalent on exterior sheathing
One layer of lasso of outer hoop.Each point constrains exterior sheathing to the purlin 100 of this annular in the circumferential, so that 100 inside of purlin
Each piece of module can be constrained very well.And due to the structure of purlin 100 itself annular, it has the function of self-balancing,
Therefore it is identical to the effect of contraction of each module.
When purlin 100 is located at the inside of inner template, since purlin 100 is ring structure, it is equivalent to and is set in inner template
One layer of support ring is set.The purlin 100 of this annular equal support internal mould plate of each point in the circumferential, so that 100 outside of purlin is every
One piece of module can be constrained very well.And due to the structure of purlin 100 itself annular, it has the function of self-balancing, because

100 housing of purlin at the outside of exterior sheathing, purlin 100 by gravity more slide downward, can bind round tighter instead, therefore even if
Without using outer support structure, purlin 100 can also constrain exterior sheathing well.
Using the purlin 100 of the embodiment of the present invention, since the template of 100 pairs of insides of purlin or outside can be on circumferential direction
Effect of contraction is played to weighing apparatus, therefore relatively thin plate can be used in inner template and exterior sheathing.Specifically, working as one of them of template
When module deforms, the module at deformation props up certain deformation of purlin 100, and deformation force of the purlin 100 at this is scattered to
Purlin 100 is circumferential everywhere, and the entire purlin 100 under itself rigidly effect of purlin 100 resists the deformation force, so that the module can be fast
Quick-recovery is to original position.Exactly purlin 100 can play effect of contraction to template everywhere circumferential, therefore template itself can not have to setting
It obtains excessively heavy.After template mitigates, integral construction burden can be mitigated.
The purlin 100 of the embodiment of the present invention is rigid member it can be seen from the use process of above-mentioned purlin 100, thus
It can provide inner and outer template enough support restraining forces.
When outside of 100 housing of purlin in exterior sheathing, the internal diameter of purlin 100 and the outer diameter of exterior sheathing are generally equalized；When
When purlin 100 is located at the inside of inner template, the outer diameter of purlin 100 and the internal diameter of inner template are generally equalized.That is, purlin
100 needs are corresponding consistent with corresponding template size, could preferably play constraint supporting role.
