As depicted in figs. 1 and 2, according to the purlin 100 for tower pouring construction of the utility model embodiment, purlin 100 enclose section 10 with multiple, and multiple sections 10 of enclosing circumferentially join end to end, and purlin 100 is formed as ring structure, in this way, to tower Before cylinder is poured, 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 utility model embodiment, exactly it is applied to the construction of this concrete tower segments, in coagulation Soil is set on formwork for placing before pouring.Purlin 100 can housing in the outside of the exterior sheathing installed, purlin 100 can also be set In the inside of the inner template installed.

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 This it be identical to the supporting role of each module.

Here, when outside when 100 housing of purlin in exterior sheathing, outer support structure can also be set in the outside of purlin 100. When purlin 100 is located at the inside of inner template, inner support structure can also be set in the inside of purlin 100.These inner support structures and The setting of outer support structure can further strengthen the constraint supporting role to template.

In the embodiment having, the diameter dimension of tower ontology is sequentially reduced on direction from bottom to top, therefore is worked as and enclosed 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 utility model embodiment, since the template in 100 pairs of insides of purlin or outside is on circumferential direction Effect of contraction can be balancedly played, therefore relatively thin plate can be used in inner template and exterior sheathing.Specifically, working as template wherein When one module deforms, the module at deformation props up certain deformation of purlin 100, and deformation force of the purlin 100 at this is equal It is circumferential everywhere to be scattered to purlin 100, the entire purlin 100 under itself rigidly effect of purlin 100 resists the deformation force, so that the module Can fast quick-recovery to original position.Exactly purlin 100 can play effect of contraction to template everywhere in circumferential direction, therefore template itself can not have to It is arranged excessively heavy.After template mitigates, integral construction burden can be mitigated.

The purlin 100 of the utility model embodiment is rigid member it can be seen from the use process of above-mentioned purlin 100, So as to provide inner and outer template enough support restraining forces.
